The immune system can also get sick and even be life-threatening.

　　"Wang Lin, a qigong master, died of multiple organ failure due to ANCA-related vasculitis and autoimmune peripheral neuritis." This news brought "immune system diseases" into public view.

　　In the course of millions of years of evolution, human beings have formed a complex defense mechanism against foreign microorganisms and harmful substances. This defense mechanism has a clear division of labor and powerful functions, and can cope with the changes and challenges of the living environment. We call it "immune system".

　　But like other organs of the human body, the immune system will get sick and even be life-threatening. What’s wrong with this?

　　The innate immune system is derived from invertebrates.

　　The normal immune system consists of immune organs, immune cells and immune molecules.

　　Immune organs mainly refer to lymph nodes, spleen and thymus. Among immune cells, there are cells involved in immune response and immune regulation, mainly T lymphocytes and B lymphocytes. Among them, T lymphocytes come from thymus and play an important role in the regulation of immune response, while B lymphocytes are mainly involved in the formation of antibodies, including autoantibodies. Immune molecules are mostly synthesized and secreted by immune cells, which play an important role in the initiation and regulation of immune response and the attack on tissues and organs.

　　Humans have inherited the innate immune system of invertebrates in the process of evolution. This ancient defense system identifies invading external pathogenic microorganisms through germinal cells widely distributed in human immune organs; Through the macrophages of innate immune system, we can identify the virulence factors of main microorganisms, directly kill pathogens and protect human body. This kind of protection is an immune response that is quickly started and mobilized, and it is non-specific. That is to say, innate immunity is reacted and cleared in the same way for any foreign microbial invasion, so it is not the most effective.

　　However, while the innate immune system slows down infection, it will activate the acquired immune system-the acquired immune system. Acquired immunity will react specifically to foreign antigens or pathogens. After the first contact with antigens, the second contact with the same antigen can trigger a faster and stronger immune response, attack foreign antigens and remove them from the body.

　　In short, the normal immune system has three important characteristics: one is a variety of antigen receptor libraries, which can identify almost endless pathogens; The second is immune memory, which can initiate a rapid memory immune response, which is why we can be immune for life after injecting some vaccines; The third is immune tolerance to avoid immune damage to normal self-tissues.

　　Distinguish the Immune Tolerance of "Friend or Foe"

　　The most important function of so-called "immunity" is to identify "self" and "non-self", and it will not produce immune response to its own tissue components, which is called immune tolerance.

　　The human body can achieve immune tolerance through autoantigen isolation, so that its own tissues can not contact with the immune system, and the specific immunity of related T or B cells is "unresponsive". For the "non-ego" of foreign microorganisms or foreign tissues and organs introduced into the body, the immune system will protect the body from the damage of intruders by starting an immune "response" reaction.

　　Therefore, if the function of the immune system is disordered and the normal components of the body are regarded as foreign substances, autoimmune diseases will occur. From the pathogenesis, autoimmune diseases are diseases caused by the breaking of immune tolerance. The immune system cannot correctly identify "self" and "non-self", thus attacking its own tissues and organs.

　　In addition, the dysfunction of T cells with the function of regulating immunity can not stop or inhibit the immune response in time, which will also lead to the occurrence of autoimmune reaction.

　　Autoimmune diseases are related to genes.

　　It is necessary for us to understand the role of genes in autoimmune diseases.

　　In the process of immune response, many auxiliary molecules are needed to produce specific immune response against foreign microbial antigens. Among them, the most important helper molecule is MHC (major histocompatibility complex). T cells can be activated and the subsequent immune response can be initiated only after the foreign microbial antigen and MHC molecules combine to form a complex.

　　MHC is usually called human leukocyte antigen (HLA), and its related gene is located on chromosome 6. HLA antigen complex is regarded as the genetic determinant of immune activation. In other words, HLA mainly determines the characteristics of immune response and the occurrence and development direction of immune response. At present, more and more genetic studies show that HLA determines a person’s susceptibility to many diseases, especially autoimmune diseases. People who carry these susceptibility genes have a much higher risk of autoimmune diseases than the general population.

　　In reality, scientists have found some susceptible genes related to autoimmune diseases. It is certain that human immune response is influenced by genetic factors, and some autoimmune diseases have genetic tendencies.

　　People with genetic susceptibility should beware of "molecular simulation"

　　Generally speaking, autoimmune diseases often occur in genetically susceptible people. Their immune cells have abnormal functions, and they will get sick when they encounter suitable external triggers.

　　These external triggers include microorganisms, such as some bacterial or viral infections, and some harmful substances in the environment, such as smoking. For example, some microbial antigens, such as staphylococcal protein A and staphylococcal enterotoxin, can stimulate T or B cells, making these cells transform into autoreactive T or B cells, leading to autoimmune reactions.

　　In addition, because the components of some microorganisms are similar to the fragments in normal human tissues, the normal immune response to foreign microorganisms will activate autoimmune lymphocytes in the form of "molecular simulation" or cross-reaction, causing autoimmune reactions. The most typical autoimmune disease caused by molecular simulation is rheumatic fever. The anti-Streptococcus M protein antibodies in rheumatic fever cross-react with actin, laminin and antigens of nervous system, and start inflammatory reaction in the heart, causing rheumatic heart disease. If these antibodies enter the brain tissue, they can cause chorea. Studies have shown that in type I diabetes, rheumatoid arthritis and multiple sclerosis, there is a "molecular simulation" effect between this microbial protein and human tissues.

　　In a word, the immune system is a delicate and complex barrier to protect the body from external harm. However, the pathogenesis of autoimmune diseases is very complicated, so far, the exact pathogenesis of a considerable number of diseases has not been fully studied. It should be noted that after the occurrence of autoimmune diseases, patients should seek medical advice in time, diagnose and treat early, so as to avoid irreversible damage to important organs.

　　Since 1941, the Japanese invaders have stepped up their "mopping up" and "nibbling away" against the anti-Japanese base areas, especially the anti-Japanese base areas in North China, and launched a "campaign to strengthen public security", targeting the anti-Japanese base areas led by the Communist Party of China (CPC) and their armed forces as the main targets. The anti-Japanese war behind enemy lines in the base areas entered an unprecedented difficult period, and the puppet troops launched a heroic and tenacious struggle on the same day. The "Five Heroes of Langya Mountain" is an anti-Japanese hero group in the arduous struggle between the army and the people behind enemy lines.

　　First, the battle of Langya Mountain

　　In August 1941, Okamura Ningji, commander of the Japanese North China Army, commanded more than 70,000 puppet troops (including more than 60,000 Japanese troops and more than 10,000 puppet troops) and launched an unprecedented autumn "mopping up" on the Shanxi-Chahar-Hebei border region. This large-scale "sweeping" and anti-"sweeping" struggle lasted for two months.

　　The Japanese army, with a large number of troops and fierce momentum, adopted long-range circuitous, converging attack and iron wall encirclement tactics in an attempt to destroy the Shanxi-Chahar-Hebei base area in a short time. The Shanxi-Chahar-Hebei Military Region made some preparations in advance for the "sweeping" of the enemy’s encirclement. On August 19th, the First Military Division of the Shanxi-Chahar-Hebei Military Region received operational guidelines and tactical instructions against "mopping up". Previously, the first division transformed the terrain fortifications of the Langyashan station where the main force of the army was located, and streamlined the organization. On August 23, the Japanese army began to attack. Over the past month, the battles around Yixian County have been going on.

　　Langya Mountain belongs to Taihang Mountain Range, which is southwest and northeast. It is located in the southwest of Yixian County, Hebei Province, including 5 Tuo 36 peaks including Qipaituo and Lianhuafeng. At that time, thousands of officers and men of our army and tens of thousands of people were hiding here to avoid the crazy "sweeping" of the Japanese army. In the early morning of September 23, the Japanese army began to attack Langya Mountain. The Japanese vanguard troops entrenched in Tanghu occupied Nanqi Village and Beiqi Village at the foot of the mountain, creating a massacre of many villagers. Then, the Japanese main force rushed out. At dawn, more than 3,500 Japanese puppet troops marched west from Dingxing and Fangshunqiao, and besieged a district station near Beiloushan in Yixian County. At that time, there were about 5,000 people in a district. The attack on Langya Mountain was launched by the Second Corps of the Japanese North China Army, which was composed of the 133rd Brigade of Infantry and its subordinate units. The head of the Corps was Major General Tsuda Meiwu, the head of the 133rd Brigade of Infantry.

　　With the puppet troops of the traitor Zhao Yukun leading the way, the Japanese army moved in quickly. The Japanese army deployed heavy troops at the entrance and exit, advancing from Beiguantou along Dongxishui Village to Langya Mountain. At noon on the 23rd, the Japanese puppet troops had gathered at the foot of the mountain. At that time, the number of troops staying in Langya Mountain was not large, and there were 30,000 to 40,000 party and government organs, guerrillas and the masses in Yixian, Dingxing, Xu Shui and Mancheng counties. We must find a way to organize a breakthrough as soon as possible. Yang Chengwu, commander of the first division, ordered four guerrilla detachments to be commanded by Qiu Wei, the head of a regiment who was recovering from illness on the mountain, and asked them to take advantage of the natural barrier terrain to hold their positions and wait for an opportunity to break through. Through the "flying line", the sub-regional intelligence station learned about the main rivers, Maoerya, Guantou, Dongxishui, Songshan, Loushan, Qishui, Caiyuan, Xueyiling, Nianzitai and Jiulian Mountain where the enemy was distributed around. At dusk on the 23rd, three regiments and twenty regiments from one division attacked at the same time from Lingxi, Aisha, Liujiatai and Wujiazhuangzi in the east and west. The Japanese troops in Guanshan and Songshan suffered heavy casualties and the puppet troops suffered heavy losses. The Japanese army thought that it had encountered the main force of our army, and immediately rushed to Beilou Mountain for rescue from Jiulianshan, Nianzitai and Xuediling, and a large part of the Japanese army was attracted to it. There is a big hole more than ten miles long in this area, which greatly reduces the pressure on our army. Colonel Qiu Wei seized the favorable opportunity and quickly organized a breakthrough.

　　According to the instructions of the head of a division, a company of a regiment stayed as a cover. The task of covering the evacuation of the main force was given to a group of seven companies. The Seventh Company moved from the east to the west of Langya Mountain, and got enough bullets and grenades in a cave, with the cooperation of local militia guerrillas. On the other hand, the main force of the division moved westward from Zhouzhuang via the upper and lower passes on the evening of 23rd. Until noon on 24th, the division headquarters was safely transferred to zhang jia zhuang.

　　According to the original deployment, the Seventh Company pretended to be a main force to attract the enemy’s main force, and then took advantage of night cover and familiarity with the terrain to wait for an opportunity to attack and destroy the enemy. Liu Fushan, the company commander of the Seventh Company, and Cai Zhanpeng, the instructor, led the soldiers of the whole company to take advantage of the natural hazards and the reformed terrain of Langya Mountain, and with the cooperation of the militia, divided their forces and laid mines on the enemy’s way up the mountain. After nightfall on the 24th, guerrilla detachments, government officials and the masses in four counties moved quietly along Pantuo Road to the vacant hole. At about 12 o’clock in the middle of the night, Class Six crossed Langya Mountain and came to the small village behind the mountain. The seventh company sent the first and third platoon to alert, and the second platoon was on standby. At about three or four o’clock in the morning, I received an order to cover the retreat of the seventh company and buy time for the withdrawal of the authorities. After completing the task of covering the masses to break through, the first and third rows were evacuated one after another, and the second row continued to cover. The company commander ordered the second platoon and the second squad to guard the north foot of the mountain and the sixth squad to guard the east entrance. After the second class left, the company commander took seven commanders and soldiers to evacuate along Pantuo Road, leaving the machine gun group to the sixth class to occupy the Xishan Pass, attracting enemy fire and continuing to cover the battle. The two men in the machine gun group were equipped with two machine guns. Ma Baoyu, the squad leader of Class Six, Ge Zhenlin, the vice squad leader, and five soldiers, including Hu Delin, Hu Fucai and Song Xueyi, bundled several boxes of grenades left by the regimental headquarters by moonlight, and then hid them in the most dangerous strongholds of "Yan Nose" and "Little Face" on the chessboard tuo.

　　On the morning of 25th, more than 500 Japanese puppet troops launched an attack on Langya Mountain. On the way up the mountain, the Japanese army from Dongxishui Village to Qipaituo fell down with the explosion of mines. The two-way firepower of the machine gun group attracted the enemy, who mistakenly thought that there was still the main force of our army on the mountain. Five soldiers, including Ma Baoyu, were divided into two groups to stop the enemy who tried to meet at Qipaituo. However, the machine gun even had limited bullets, and the machine gunner retreated after finishing the bullets. In order to stall the Japanese army, Class Six soldiers have been leading the enemy up the mountain. The Japanese army suffered losses in the previous attack and dared not act rashly. They took the form of strafing and shelling, probing in small groups and taking turns to attack. Six classes of soldiers guarded the main road of the chessboard tuo, fought bravely and held their positions, repelled four fierce Japanese charges and killed more than 50 enemies. Until noon, the Japanese did not climb the chessboard tuo. Chessboard Tuo has one road leading to the direction of the main force transfer, and the other is the road leading to the peak of Chessboard Tuo, which is also a dead end. In order not to expose the transfer route of the troops and ensure the safety of the main force, five soldiers chose to retreat to the top of Qipaituo. Ma Baoyu, the squad leader, led the soldiers to climb the top while shooting at the enemy relying on rocks and Woods. The enemy is in hot pursuit. Because the enemy is not familiar with the terrain, some of them were shot and rolled down the mountain, while others stepped on stones and fell into deep valleys. Class six soldiers led the enemy to the top of the road, but also got themselves into trouble.

　　There are three cliffs on the top of the chessboard, and there are no obstacles to rely on, no way back. Five strong men, led by monitor Ma Baoyu, fought fiercely with the enemy for five hours. When the ammunition is used up, throw stones at the enemy. They played out the last bullet and threw the last Grenade, but it was difficult to support them because of the disparity between them. At the last critical juncture, the five warriors would rather die than surrender. After destroying their guns, they jumped off the cliff. Ma Baoyu, Hu Delin and Hu Fucai died heroically, while Ge Zhenlin and Song Xueyi jumped off the cliff and hung on the branches of the cliff, but they survived. Ge Zhenlin was slightly injured, and Song Xueyi broke his waist. With their instinct for survival and tenacious perseverance, the two men climbed the cliff with difficulty, encouraged and helped each other to walk to Xiaoshilin and met Taoist Li, a local Taoist temple. After their rescue, they were taken to the hospital by the militia. The battle in Langya Mountain is over. The feats of five soldiers, including Ma Baoyu, who swore to the death to resist Japan, showed the noble quality of the people’s army led by communist party and the unconquerable heroism of the Chinese nation.

On March 26th, the first domestic proton therapy system was used to treat more than 100 patients.

Proton therapy is an anti-cancer weapon, one of the most advanced tumor radiotherapy methods in the world, a "tumor directional blasting artifact" and a "jewel in the crown of tumor radiotherapy". Protons can fully protect the normal tissues around the tumor and achieve a "precise attack" on the tumor.

On the same day, reporter The Paper (www.thepaper.cn) learned from the Tumor Proton Center of Shanghai Ruijin Hospital that the first domestic proton therapy system was put into trial operation in the hospital on July 19th, 2023. After the treatment fee standard was approved by the state, the Tumor Proton Center of Shanghai Ruijin Hospital officially started operation on November 24th, 2023. In just over four months, the number of clinical patients has reached 100. The tumor diseases covered include head and neck tumors, breast cancer, chest tumors, abdominal and pelvic tumors, spine and trunk and limbs tumors, etc. There are adults and 3 children and adolescents in the treatment patients.

In view of the treatment cost, the hospital revealed that the charging standard is that each course of treatment for the same indication does not exceed 170,000 yuan. In addition, the hospital also said that in order to better serve tumor patients, Ruijin Hospital opened outpatient clinics in Ruijin Hospital General Hospital in Huangpu District and Tumor Proton Center in Jiading District every Monday to Friday, and the radiotherapy department of the hospital took the lead in setting up a clinical pioneering and innovative team of domestic proton therapy system, including medical staff, physicists and technicians, to escort proton therapy in an all-round and full-cycle manner.

On March 26th, the first domestic proton therapy system was used to treat more than 100 patients, and the 100th patient, Aunt Chen, took a group photo with medical staff and therapists. Photo courtesy of Ruijin Hospital

Among the 100 cases treated, more than 20 tumor species were covered.

Aunt Chen, who is 70 years old, is the 100th patient treated by this proton system. Her symptoms of sacral pain have lasted for more than 10 years.

In July, 2022, Aunt Chen found a huge mass in the sacrococcygeal bone after magnetic resonance examination in a hospital, and then went to Ruijin Hospital for PET-CT examination, which was suspected to be a malignant lesion. Subsequently, the surgical and pathological examination showed that the common chordoma involved the soft tissue beside the bone. In February 2024, Aunt Chen relapsed more than one year after surgery.

After the recurrence, Aunt Chen received the first domestic proton therapy system, and the whole radiotherapy process lasted about 40 minutes. "For this patient, proton therapy can effectively protect the rectum and sigmoid colon while giving enough dose to the tumor." Chen Jiayi, director of the radiotherapy department of Ruijin Hospital, said that proton therapy can not only greatly reduce the side effects, but also effectively improve the curative effect of curing tumors. Patients with solid malignant tumors may benefit from proton therapy, especially in the treatment of central nervous system tumors, head and neck tumors, chordomas in various parts, left breast cancer, prostate cancer, mediastinal malignant lymphoma and childhood tumors.

Among the 100 patients treated by the first proton therapy system made in China, there were also 3 children and adolescents. The treatment process was smooth and safe without obvious discomfort.

The 14-year-old girl Xinxin (a pseudonym) is one of them. She was diagnosed as central diabetes insipidus, growth hormone deficiency, pituitary hypofunction and gonadal hypofunction in a hospital more than four years ago due to symptoms such as dry mouth, polyuria and stunted growth. In July 2023, this child went to Ruijin Hospital for diagnosis because of his short stature and decreased bone mass, and was finally diagnosed as pituitary germinoma.

From August 28th to September 27th, 2023, this girl began to receive the first proton therapy system made in China. During radiotherapy, diabetes insipidus gradually improved and her height also increased. "Protons better protect the normal tissues such as brain stem and hippocampus of the child. After three months of radiotherapy, her intracranial lesions shrank obviously and her height increased by 6 cm." Chen Jiayi said.

Chen Jiayi said that among the 100 cases currently admitted, including 29 cases of head and neck, 35 cases of breast cancer, 22 cases of chest tumors, 9 cases of abdominal and pelvic tumors, and 5 cases of spinal and trunk tumors, more than 20 kinds of tumors can be treated now, not only radical treatment, but also postoperative assistance, postoperative recurrence, postoperative residue, and few metastatic radiotherapy.

Zhao Ren, vice president of Ruijin Hospital, said that since the clinical treatment, the proton therapy professional team in radiotherapy department, including clinicians, physicists, technicians and nursing staff, has ensured the safe and effective proton therapy in all directions, ensuring the maximum benefit of proton therapy for every patient. Up to now, all patients have been successfully treated, and there is no treatment toxicity of degree 3 or above, and some patients have shown good short-term efficacy.

The maximum duration of treatment for the same indication is not more than 170,000 yuan.

Zhao Zhentang, an academician of China Academy of Engineering and director of Shanghai Light Source Science Center, also said that the first proton therapy system made in China adopts the internationally advanced IMPT-PBS (full name: pencil beam scanning intensity-modulated proton therapy) technology, which can "scan layer by layer" bit by bit, realize three-dimensional carved dose coverage, and achieve "lower toxicity and more accuracy" to the greatest extent. Proton fixed beam and 180-degree rotating beam are carried out in parallel. The fixed beam is accurate and efficient, and the 180-degree rotating beam is free and flexible, which can realize the individualized radiotherapy scheme for each patient more comprehensively.

Chen Jiayi said that since the beginning of clinical treatment, the patients admitted have both the "traditional strengths" of proton therapy and the "China characteristics", which fully reflects the "rooting" of proton therapy in the medical field in China.

"Head and neck tumors are the traditional strengths of proton therapy. The head and neck are often adjacent to multiple key normal organs, and functional protection is particularly important. Head and neck tumors often need higher therapeutic doses. Proton therapy can achieve a good balance on the seesaw of curative effect and toxic reaction." Chen Jiayi further indicated that the treated patients with head and neck tumors included not only skull base tumors of various pathological types, but also meningiomas, pituitary tumors, gliomas, adenoid cystic carcinoma and so on, which remained or recurred after operation.

However, the "China characteristics" of domestic proton therapy are obvious in domestic high-incidence species such as breast cancer, lung cancer, esophageal cancer and other chest tumors.

"For breast cancer patients, from breast-conserving postoperative radiotherapy, mastectomy postoperative radiotherapy, combined regional lymph node irradiation, reconstruction postoperative radiotherapy, to locally advanced radical radiotherapy, and then to radiotherapy for patients with recurrence and oligometastasis, the first proton therapy system in China covers almost all clinical scenarios of breast cancer radiotherapy. There are no adverse reactions such as radiation dermatitis of degree 2 or above, breast edema, radiation pneumonia and sore throat in the treated patients." Chen Jiayi said.

In view of the treatment cost, the hospital revealed that the charging standard is that each course of treatment for the same indication does not exceed 170,000 yuan. Specifically, the first proton treatment cost is 40,000 yuan, and then each additional treatment will be charged 15,000 yuan. The maximum treatment for the same indication does not exceed 170,000 yuan. It is worth mentioning that this treatment has also been included in "Huhuibao".

Zhao Zhentang also introduced that for proton therapy, the multi-angle and control technology of rotating beam is the most critical technology. At present, the 360-degree rotating beam treatment system is being debugged. Compared with the 180-degree rotating beam treatment system that has been put into use at present, the new generation system will be more accurate in treatment positioning and more conducive to improving treatment efficiency.

"According to the current plan, the 360-degree rotating beam treatment system is expected to be debugged in October this year and gradually opened to patients." Zhao Zhentang said.

1905 movie network news On July 15th, the film released the theme song "Stubborn" MV, and cooperated with the famous rock band for a dream-chasing trip in this summer. The film was directed by, written by Dapeng, served as the chief producer, and starred in,,,, featuring Casper, Wang Feifei and Zhang Haiyu, starring Liao Bo, Wang Hai, George, Yang Xiaojian, Zhou Senlin, Mo Shaoqing, Zhang Yunchen and Han Mo, and starring Zhang Youwei and Yang Di in friendship. The film tells the story of hip-hop mr. six Ding. — Exclamation mark The masters in the dance troupe are like clouds, with different personalities, and they collide with Chen Shuo with different sparks and jokes. Chen Shuo cherished this stage very much and looked forward to the opportunity to play, only to find that everything was not as smooth as expected.

　

Love, fear of mountains and roads, and play the youth movement enthusiastically.

The MV "Stubborn", the theme song of the movie "Passionate" released this time, shows the obstacles, difficulties and setbacks that Chen Shuo, a dancer with a dance dream, has encountered on the road to dream, and his persistent persistence, persistence and struggle. In the song full of warmth and strength in May, Chen Shuo’s determination to get up after falling down again and again is more deeply presented: to repair a car as a waiter to supplement his family, to train repeatedly in the subway alone, and to be persuaded by the dance troupe not to give up any chance to play … …

"My last stubbornness and I will never let go of our hands." This is Mayday’s high and inspiring lyrics, but also Chen Shuo’s desire to realize his ideal. When the burden of life is unbearable, when the lights on the stage are as far away as Tian Yue, and when you can only pull yourself between reality and dreams, courage and firmness have become the most distinctive pronouns for dream catchers. As long as you go all out, as long as you are far away, you will be able to find your own value. Firm love, always "warm"!

　　BEIJING, Beijing, May 28 (Reporter Yuan Xiuyue) There are still 10 days before the 2023 college entrance examination. In another 10 days, students from all over the world will set foot on the examination room and usher in an important exam in their lives.

　　As the first college entrance examination under the new situation of "Class B and B Management" in COVID-19, what are the new changes in the college entrance examination in 2023? How to deploy the college entrance examination in various places?

　　The number of applicants in many places has risen to record highs in Hunan and Sichuan.

　　The national unified examination for the 2023 college entrance examination began on June 7, and the specific subject examination schedule is: Chinese from 9:00 to 11:30 on June 7; Math from 15:00 to 17:00. On June 8, 9:00 to 11:30, liberal arts comprehensive/science comprehensive; From 15:00 to 17:00, if there is a foreign language listening test, it should be arranged before the written foreign language test begins.

　　The names of examination subjects in all provinces (autonomous regions and municipalities) are the same as those in the national unified examination subjects, which must be consistent with the national unified examination schedule. The time of provincial unified examination and college entrance examination shall be determined and published by the provincial recruitment committees and colleges and universities in accordance with the relevant requirements of the Ministry of Education.

　　Recently, many places have announced the printing of admission tickets and the exact test time.

　　Recently, some areas have also announced the situation of this year’s college entrance examination. It can be noted that the number of applicants in many places has increased, and some places have reached record highs. For example, in 2023, there were 684,000 applicants for the college entrance examination in Hunan Province, an increase of 29,000 over the previous year, and the number of applicants reached a record high. According to media reports, this year, the number of applicants for the college entrance examination in Sichuan Province exceeded 800,000, a record high.

　　In addition, the number of applicants for the college entrance examination in Yunnan Province reached 399,300 this year, an increase from 388,300 last year. Among them, there are 355,700 ordinary high school students and 43,600 "three school students"; There were 32,500 people who took the examinations for arts majors and 18,800 people who took the examinations for sports majors.

　　This year, the number of applicants for the college entrance examination in Gansu Province totaled 247,848, an increase of 4,600 over last year. Among them, 196,678 candidates participated in the general college entrance examination.

　　To prevent mobile phone cheating, many places are equipped with intelligent security doors for the first time.

　　This year, the prevention of mobile phone cheating is the top priority in all localities, and many examination rooms are equipped with intelligent security gates for the first time.

　　For example, according to Yunnan Province, all examination rooms are standardized this year, and all test sites are equipped with intelligent security gates for the first time. All candidates can enter the test sites only after being tested by the intelligent security gates. At the same time, candidates have to carry out manual security check before entering the examination room, and resolutely block the mobile phone outside the test center. All test centers have achieved full coverage of 5G mobile phone signal shielding.

　　Jiangxi Education Examinations Institute’s "Open Letter to Candidates of the General College Entrance Examination in 2023" also stated that this year’s college entrance examination has added a security gate, and candidates need to undergo double security checks at the test center and examination room. Candidates are strictly forbidden to bring mobile phones, smart watches, headphones and other electronic devices into the examination center.

　　Henan Education Examinations Institute also introduced in "A Letter to Candidates of the 2023 College Entrance Examination" that the province has carried out special treatment for cheating on mobile phones, equipped with intelligent security doors, and implemented "intelligent security inspection" and "silent admission", uniformly equipped with stationery, screened and verified doubtful candidates with big data, randomly arranged examination rooms, invigilation across counties, video invigilation, cross-city online patrol, and so on.

　　At the video teleconference on the safety work of college entrance examination in Hunan Province in 2023, it was also required to complete the full coverage of the construction of intelligent security gates at test sites by the end of May, and resolutely block high-tech cheating equipment such as mobile phones from the test sites.

　　Clarify candidates’ epidemic prevention policies in many places.

　　In terms of epidemic prevention and control policies, many places have been adjusted to varying degrees. For example, according to the requirements of Fujian Province, it is necessary to adhere to scientific and accurate epidemic prevention and control requirements in accordance with the "Class B and Class B Management" and strengthen the epidemic prevention guidance for candidates and parents.

　　A Letter to Candidates of the Summer College Entrance Examination in Shandong Province in 2023 requires that candidates should do a good job in health monitoring. 3 days before the test, we will carry out health monitoring independently. If there are suspicious symptoms such as fever, we should immediately carry out nucleic acid or antigen detection. If the result is positive, we should take the initiative to contact the education entrance examination institution where the test center is located for filing and take the test in the standby examination room of the test center according to the relevant requirements.

　　If there are suspicious symptoms on the day of the exam or during the exam, antigen testing will be conducted on the spot, and candidates who are positive will be arranged to take the exam in the standby examination room. Candidates in the alternate examination room must wear masks in a standardized manner throughout the whole process.

　　The letter also said that candidates should not go out or gather before the exam, do personal protection, keep a regular diet and work and rest, and ensure that they meet the exam in the best condition.

　　The "Open Letter to Candidates of General College Entrance Examination in 2023 in Jiangxi Province" also requires that self-health monitoring and personal protection should be done well before the exam to minimize unnecessary gathering activities and reduce the risk of epidemic infection.

　　In the Letter to Candidates of the General College Entrance Examination in 2023 issued by Heilongjiang Province, it is mentioned that although the epidemic prevention and control in COVID-19 is implemented with "Class B and Class B management", we should do a good job in personal protection, reduce the gathering and flow before the exam, do not go to crowded places, and be the first person responsible for our own health.

　　As an American muscle model, the 23 Dodge models need to be a little sloppy and rough to be more American. There is such a car, when you first see it, your heart is a little throbbing, and at the same time, you are more appreciative.

　　In terms of space, the challenger is also doing the best. Both the ride space and the trunk space are the largest. I have experienced the back row of Mustang and Challenger before. It is not a big problem to sit in the back row of the co-pilot, but the head space in the back row of Mustang is much worse than that of Challenger. But it’s better not to sit in the back row of this kind of car. It’s really not as comfortable as any family car.

　　CCTV News:Environmental control and life support system plays a very important role in manned mission, which is directly related to the health and life safety of astronauts. Astronauts’ daily living in space station and extravehicular activities are inseparable from the escort of open-loop life support system.

　　Reclaimed water, reclaimed oxygen, environmental control, life guarantee and reuse of resources

　　In order to realize long-term economic operation, China’s space station can collect the water vapor exhaled by astronauts through condensation and drying components, and then convert it into drinkable reclaimed water through purification devices, and urine can also be collected and treated as drinkable pure water. At the same time, the electrolytic oxygen production system can use circulating water to electrolyze oxygen production. In addition, carbon dioxide can be purified in the space station cabin, and the enriched carbon dioxide can react with hydrogen generated by electrolytic water, so that considerable water can be obtained, the closed-loop degree of material utilization can be improved, and the materials of the space station can be recycled as much as possible. Environmental control life support system provides basic guarantee for astronauts to survive, live and work in space environment, and is a key component of manned spacecraft.

　　The extravehicular service itself has a portable environmental control life support system.

　　Environmental control life insurance also plays a very important role in astronaut extravehicular activities. The extravehicular clothing worn by astronauts in extravehicular activities also has a portable environmental control life support system, so that astronauts can get the necessary oxygen after wearing extravehicular spacesuit. In this suit, there are also many complicated systems such as temperature and humidity control system and condensed water collection system.

　　In the process of leaving the cabin, the gas in the airlock cabin is pumped to the living cabin.

　　Compared with short-term in-orbit flight, every gram of gas is very precious in medium-and long-term in-orbit mission. During the astronauts’ extravehicular activities, the scientific and technical personnel pumped the gas from the airlock cabin to the living cabin through the gas reuse system, and then replenished the living gas to other cabins when the astronauts returned from the extravehicular activities, thus realizing the gas reuse.

　　The environmental control and life support system of China Space Station is operating normally.

　　At present, astronauts have been flying in orbit for two months, which is also the longest space mission in China so far. According to experts, all the functions of environmental control life insurance are working normally.

[car home Performance Test] For many home users, although buying new energy vehicles can avoid the troubles of purchase restriction, due to the lack of charging conditions, it will be more or less inconvenient to use them later, especially in the case of long-distance running, and it is necessary to plan the route in detail in advance. For plug-in hybrid vehicles, this series of troubles may be alleviated a lot. The car I brought to you today is the Buick (|) plug-in hybrid model that Buick listed at this year’s Chengdu Auto Show.

● Review of exterior interior:

Previously, my colleagues had a field test drive on this new car model, and the exterior and interior of this car are basically the same as the pure electric version of the micro blue 6, so in this article, we only make a simple review of the exterior and interior of the vehicle and the space of the vehicle. First of all, let’s talk about the appearance design. The overall appearance design of the vehicle is no different from that of the pure electric version. The difference is that the middle net of the plug-in hybrid version has been changed to an open design, rather than a fully enclosed shape like a pure electric vehicle.

● Space experience

The experiencer is 173cm tall and enters the front row of the vehicle in a standard sitting position. At this time, the head space has one punch and two fingers, and the knee space in the second row has more than two punches, but the head space in the back row is not enough.

● Storage space

The storage space before and after is quite satisfactory, and there is no surprising configuration, but in general it is very sufficient. Although there is no popular design of hollowing out the bottom of the handlebar seat to make storage space, there is a storage compartment next to the passenger seat, which can hold some small things.

The performance of the trunk space of the vehicle is satisfactory. Under normal conditions, we can put down our three experience boxes, and there is no problem for daily use. The second row of seats can be laid down at a ratio of 4/6, and a flat space can be formed, which is not a problem to deal with some big items occasionally. At the same time, the equipped electric tailgate also provides enough convenience for daily use.

● Power system

The plug-in hybrid vehicle is equipped with a 1.5L four-cylinder naturally aspirated engine and two motors. The total power of the system is 135 kW and the comprehensive torque is 380 Nm. In terms of battery, the vehicle uses a ternary lithium-ion battery with a capacity of 9.5kWh. The Ministry of Industry and Information Technology announced that the cruising range of pure electricity reaches 60km, and it takes 2.6 hours to charge slowly.

As for the E-CVT gearbox, it contains two permanent magnet synchronous motors, which can be used to drive or generate electricity independently. Among them, power split technology can provide two power split modes of high speed and low speed and more than 10 working modes. For the highlights of this brand-new eMotion electric drive technology, please refer to this article: "SAIC-GM announces the highlights of new eMotion electric drive technology"..

The vehicle adopts three driving modes (normal/sport/power conservation). Press the Hold key to keep the power as much as possible, and then start to use the power when it is needed (for example, in traffic jams). However, compared with many models, the engine can be used to charge the vehicle, and the power conservation mode of Micro Blue 6 can only maintain the current power.

● Power experience

When the vehicle is fully charged and in normal mode, it will give priority to electric drive. At this time, the driving experience of the vehicle is very similar to that of ordinary pure electric vehicles, and even if the throttle is relatively large, the engine will not easily intervene. When stepping on the accelerator pedal, the feeling of vehicle acceleration is very smooth and natural, and the whole is comfortable, and there will be no dizziness caused by the instantaneous force of many electric vehicles.

The dynamic response of the vehicle is also satisfactory, and the middle and rear sections can also have certain acceleration ability. After switching to sports mode, the response speed of the accelerator pedal becomes faster and the power output is more positive. In terms of braking, the vehicle doesn’t use the single pedal logic of pure electric vehicle, so it won’t have a very strong drag feeling when receiving oil or stepping on the brake. Generally speaking, its power performance is still very mature, but it is not without any faults to pick. Perhaps it left a good impression on people in the pure electric mode at first. Once the vehicle entered the low-electric mode, the engine began to intervene. At this time, although the whole driving experience is not much different, the noise of the engine will still be obviously transmitted into the vehicle, which will affect it.

● Accelerated testing

The official acceleration of 0-100km/h is 8.6 seconds, and the actual test results are satisfactory. Finally, the acceleration of 0-100km/h is 8.25 seconds, which is quite good compared with pure electric vehicles or competing vehicles.

● Pure battery life test:

In the energy consumption test, we tested its pure electric cruising range at an average speed of 30km/h, and turned on the air conditioner all the way, with automatic air volume and temperature of 24. In the end, we measured that the pure electric cruising range of the vehicle was 70km, which was longer than the official mark. After entering the low-power mode, we continued to test the fuel consumption.

● Low power consumption: 4.7L/100km

Next, let’s take a look at the fuel consumption performance of the car under the condition of low battery. After the vehicle automatically enters the hybrid mode, we keep the original settings and continue driving. Compared with the pure electric mode, although the low electric mode can also recover some electric energy and use it at the start, it mainly relies on the power of the engine to drive the vehicle, and will bring some vibration and sound, which is not as quiet and comfortable as the pure electric mode. In the end, we drove another 102 kilometers and consumed 4.84L of fuel, which translates into a low-power fuel consumption of 4.7L. If the pure battery life is counted, the comprehensive fuel consumption of Micro Blue 6 is 3.6L.

● Chassis structure+driving experience

The suspension structure is no different from the pure electric vehicle, and it is the configuration of front McPherson+rear multi-link. From the picture, we can see that the battery under the chassis of the original pure electric vehicle is no longer there, but moved below the trunk.

The chassis adjustment of the vehicle is not very soft, but some European cars are solid and tough. When passing through uneven roads, the comfort performance is remarkable. When passing through some potholes at high speed, although there will be bouncing, the vehicle can restrain the body and ensure the stability of high-speed driving. In terms of handling, the steering feel is neutral, which is suitable for most drivers. The performance of road feeling is not sufficient, but the performance of directivity is good, and it is flexible enough when driving in urban areas.

● Brake test

In the braking test, the posture of the vehicle leaning forward is still obvious, but fortunately, the rear wheel can pull the body in time. The braking distance of 42.03 meters at 100-0km/h can only be said to be quite satisfactory. Judging from the results of several groups of brake tests, after many times of full braking, the whole braking distance has not increased very much. The brake foot feels very feedback and the strength is easy to control.

● Noise test

Finally, the noise test shows that the quiet performance of the vehicle at medium speed cruising is still acceptable, and subjectively, there is not much noise introduced into the vehicle. With the increase of vehicle speed, the noise will become more obvious after the engine is involved, which reflects the sense of advanced vehicle.

Summary:

As a new energy vehicle, the launch of Buick Micro Blue 6 plug-in hybrid version enriches the original product line, giving consumers who are worried about battery life another practical choice. The vehicle design is not much different from the pure electric version, and it still maintains the unique shape of new energy vehicles. The performance in configuration is quite satisfactory, and the power performance is still worthy of recognition. The driving experience under the condition of electricity is very good, and overtaking at medium and high speeds can also give drivers enough confidence. The overall performance of the chassis and steering feel is in line with home use, which is comfortable enough, but the noise performance in low-power situations is relatively general. Compared with some competitors of the same level, it has a quite good pure electric cruising range, and it is a good choice for consumers in many cities with limited purchases or restrictions.
