With the end of the college entrance examination, many hospitals in Shanghai are experiencing a peak of students taking off their mirrors after the exam. Recent data from the Shanghai Eye Disease Prevention and Control Center shows that the number of myopia surgeries has increased significantly compared to last year's college entrance examination, with a 50% increase in recent surgeries compared to before. Experts remind that although myopia surgery is good, not everyone can do it, and sufficient preparation and scientific selection should be made.

High school student Xiao Zhang is preparing to undergo full femtosecond laser myopia correction surgery. He has 400 degree myopia in both eyes, accompanied by 75 degree astigmatism in the left eye and 25 degree astigmatism in the right eye. He has been suffering from myopia for many years while wearing glasses. "I have long made up my mind that the first thing after the college entrance examination is to undergo myopia surgery, in preparation for smoothly applying to police academies in the future!" The reporter learned that many candidates choose myopia surgery in the hope of breaking the visual threshold and choosing their desired major. Some students also expressed that in order to make life more convenient, they no longer need to wear glasses when playing ball or swimming in the future.

According to data from the National Health Commission, the overall myopia rate among children and adolescents in China in 2022 was 53.6%, including 14.5% for 6-year-old children, 36% for elementary school students, 71.6% for middle school students, and 81% for high school students. Myopia has become a common eye health problem among students today. "Every year after the end of the exam, hospitals experience a peak in removing glasses, but this year there are more people than in previous years. These students hope to meet the professional requirements for applying through myopia surgery." Deputy Chief Physician Zhao Liquan of the Municipal Eye Disease Prevention and Treatment Center told reporters, "Many students have completed preoperative examinations before the college entrance examination and go straight to the hospital after the exam."

At present, myopia correction surgery is mainly divided into two types: corneal refractive surgery and crystalline refractive surgery. Among them, corneal refractive surgery includes full femtosecond laser surgery, half femtosecond laser surgery, and surface ablation surgery. If the patient has moderate to low myopia and enjoys exercise, it is recommended to choose full femtosecond laser surgery. If the patient is highly myopic or has a thin cornea or other special conditions, consider intraocular lens implantation surgery. Simply put, it means making a tiny incision in the cornea of the eye and implanting a customized artificial lens into the eye to correct myopia and astigmatism. Normally, the patient's vision can be restored the day after surgery. For the vast majority of students, they can fully return to normal life and study within 1 to 2 months.

Although myopia surgery is good, not everyone can do it, let alone at any time. Zhao Liquan suggests that preparations should be made in advance. On the one hand, sufficient recovery time should be reserved for myopia surgery. On the other hand, detailed and complete preoperative examinations must be conducted for myopia surgery. It is necessary to eliminate surgical contraindications and observe whether it is suitable for myopia surgery and what type of surgery is suitable. Preoperative examination requires a series of preparations such as stopping the mirror in advance. If the soft corneal contact lens needs to be stopped for more than a week, the hard corneal contact lens needs to be stopped for more than three weeks, and the corneal reshaping lens needs to be stopped for more than three months.

The expert concluded that students should also take preventive measures in their daily lives. In addition to genetic factors, long-term close range eye use and prolonged inability to relax the eyes are the main factors causing myopia. In addition, insufficient lighting, small font size for reading, and poor posture can all lead to myopia. Excessive use of electronic products and reduced outdoor activity time are also contributing factors. Summer vacation is approaching, and children also need to prevent myopia. In addition to reducing close range fatigue and using electronic products, it is best to engage in outdoor activities and sunbathing.

Why is "Cancer King" immunotherapy ineffective? Fudan Cancer Hospital Reveals New Mechanisms of Immunosuppressive Environment for pancreatic cancer CRIP1 | Tumor | pancreatic cancer

Immunotherapy has been proven to achieve significant therapeutic effects in various solid tumors. However, for pancreatic cancer, known as the "king of cancer", immunotherapy has been ineffective. On August 4, Professor Yu Xianjun, Dean of the Cancer Hospital Affiliated to Fudan University, and Shi Si, Associate Professor of Pancreatic Surgery released a research achievement, which first found the key role of cysteine rich protein 1 in shaping the immunosuppressive microenvironment of pancreatic cancer, filled the gap in the research field of immunosuppressive microenvironment of pancreatic cancer, and provided a theoretical basis for precise immunotherapy of pancreatic cancer patients. Ductal adenocarcinoma of the pancreas is the main type of pancreatic cancer, accounting for about 90% of all pancreatic cancer. Due to its high malignancy and poor treatment effectiveness, pancreatic ductal adenocarcinoma has always been one of the most malignant tumors. In recent years, the level of surgical techniques and comprehensive treatment has been achieved

A 14-year-old girl has been experiencing symptoms such as protruding pupils, incomplete eye closure, corneal injury, restricted eye movement, and overall fatigue for several years. The physical discomfort and facial abnormalities caused by eye diseases have made her increasingly reticent, and her temperament is vastly different from before. At the Ophthalmology Department of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, the pupil has been diagnosed with a rare thyroid ophthalmopathy combined with myasthenia gravis, which requires prompt treatment. However, considering the young age of the pupil, conventional hormone and radiation therapy cannot be used. Therefore, Zhou Huifang, Deputy Director of Ophthalmology and thyroid ophthalmology expert, has developed a targeted drug combined with surgical treatment plan for it, and targeted drug treatment will be performed first. Three months ago, I was hospitalized for one week with mydriasis and received intravenous targeted drug treatment. Afterwards, I went home for observation and followed up on time

Recently, Catherine, a British girl born in the 1990s, received autologous peripheral blood hematopoietic stem cell transfusion at the Cancer Center of Shanghai Jiahui International Hospital, and was successfully discharged from the warehouse. She is now on her way back to China after being discharged from the hospital. She is also the first patient at Shanghai Jiahui International Hospital to complete relevant treatments. In 2019, Catherine was diagnosed with Hodgkin's lymphoma in the UK, and after treatment, the disease completely improved. During her work and life in China in 2021, she went to seek medical attention due to multiple enlarged lymph nodes. Pathological biopsy confirmed a recurrence of Hodgkin's lymphoma, and through combined targeted drug treatment, her condition was temporarily under control. Last year in the second half of the year, when the disease recurred, the girl began to use immunotherapy combined with targeted drugs for treatment. Expert evaluation suggests that for young patients with hematological tumors, the risk of recurrence is high and treatment difficulty is increasing in the future. Autologous hematopoietic stem cell therapy is recommended
