As the year approaches, friends of Chinese students from all over the world have already bought a variety of souvenirs and are preparing to go home for the New Year.The Chinese student at Harvard University, named Zaosong Zheng, picked something special to take home.On December 9, 2019, Zheng Zaosong, a Chinese student at Harvard University, returned to China for carrying a cancer research sample from a laboratory in private, was arrested at the airport, and faces multiple charges.Upon inspection, Zheng Zaosong’s checked luggage contained a lot of brown liquid containing cancer cells.What is it to take home with cancer cells?In the face of police inquiries, Zheng Zaosong initially lied to him as a friend. Later, he admitted that 8 of these bottles had been secretly taken from Harvard Medical School’s Beth Israel Deacon Medical Center without permission.After that, he “replicated” 11 based on the research of his colleagues.The reason for taking them back to China is that Zheng Zaosong wanted to send these cancer research samples to a domestic hospital and then publish the research results in China in his own name to develop his research career.Isn’t this stealing?It is understood that Zheng Zaosong’s research direction is bladder cancer and kidney cancer. He has excellent academic performance and has won several outstanding student scholarships in schools.But through this incident, he will face up to 10 years in prison.Take a look, the great future is ruined by “evil thoughts”. Be true to being a person and even more sincere in medical research!Let’s take a look at the research that experts and scholars who are really engaged in scientific research have done hope to change the diagnosis and treatment!01 Helping others helps “heal” yourself Recently, a new study published by the Peking University research team in the journal of the National Academy of Sciences states that altruistic behavior can reduce physical pain.What is altruistic behavior?It’s just being kind to others without expecting any reward!Researchers say that when doing altruistic behavior, the brain produces chemicals such as dopamine, which increases excitement and reduces pain in the body.To learn more about the impact of altruistic behavior on pain perception, researchers conducted four studies.In the first study, people who volunteered to donate blood after the earthquake had less pain at the needle.In another study, researchers recruited cancer patients who had been suffering from physical pain for a long time and conducted a seven-day trial.The patients were randomly divided into altruism group and control group.During personal activities, patients were asked to clean the common area for their roommates (altruistic group) or for themselves (control group).During group activities, patients in the altruistic group prepared nutritional diet plans for their roommates and shared these plans during group meetings.In the control group, a healthy nutrition diet workshop was conducted by nurses.After each activity, their pain was assessed using the Wong-Baker Facial Pain Rating Scale.The results of the study showed that pain in the altruistic group decreased over time.The decrease in pain was more pronounced when patients increased their altruistic activity.And when they were acting for personal benefit, the effect of reducing pain was reduced by at least 62%.Brother Jie: Love others is love yourself!Did you help someone today?02 Bariatric surgery can reduce the risk of skin cancer. Fat little friends have another reason to do bariatric surgery!One study showed that obese people undergoing bariatric surgery have a reduced risk of skin cancer, including melanoma.Recently, a research team investigated the relationship between bariatric surgery and skin cancer.The study was published in JAMA Dermatology.The study included data from 2007 on obese patients undergoing bariatric surgery and 2,040 patients who had obesity but received routine treatment only at medical centers, such as lifestyle recommendations.After 15 years of follow-up, patients undergoing bariatric surgery lost an average of 47.6 pounds (21.6 kg).The weight of patients who have not undergone weight loss surgery remains relatively constant, but the average weight loss or gain does not exceed 6.6 pounds (3 kg).It is worth noting that 23 people in the bariatric surgery group had malignant skin cancer or malignant melanoma.In the group without bariatric surgery, 45 people developed malignant skin cancer or malignant melanoma.In other words, the patients in the bariatric surgery group not only became thinner, they also reduced the risk of skin cancer!Researchers also found that the biggest difference between the two groups was in malignant melanoma.Among patients who had not undergone bariatric surgery, there were 29 patients with malignant melanoma, compared with only 12 in the bariatric surgery group.This means that after bariatric surgery, the risk of malignant melanoma is reduced by 57%!Is obesity also a risk factor for skin cancer?Researchers say that obesity causes chronic systemic inflammation, which provides a better environment for tumor growth.Obesity itself is also related to cancer morbidity and mortality.Brother Jie: Hold your mouth and open your legs!03 The gospel of male patients: AI can be used for prostate cancer detection and classification. Artificial intelligence (AI) has become more and more widely used in cancer diagnosis and treatment. A few days ago, a study published by Google Health in Nature published readings through AI.To achieve an accuracy rate that exceeds humans!(Click to view).Recently, researchers from Sweden have developed a method for the histopathological diagnosis and classification of prostate cancer based on AI, and found that AI has the potential to solve the bottlenecks faced by histopathology of prostate cancer today.The study was published in The Lancet Oncology.Researchers used a digital pathology scanner to digitize 8,000 biopsies taken from 1,200 50-69-year-old Swedish men and obtain high-resolution images.Approximately 6,600 samples were used to train the AI system.The remaining samples were used to test the accuracy of the AI system.The researchers also “problematically” compared the diagnosis of AI with the results of assessments by 23 world-renowned urologists.The results show that the AI system is almost perfect in determining whether a sample contains cancer cells and estimating the length of a tumor in a biopsy.When determining the severity of prostate cancer, the accuracy of the AI system is comparable to that of international experts.WHAT?Is AI going to replace humans?Researchers said that the widespread promotion of AI systems in clinical practice requires more research verification.But AI-based assessments of prostate cancer biopsies may change future medical practices and improve diagnostic quality.The idea is not to replace humans with AI, but rather to serve as a safety net to prevent pathologists from missed diagnosis and to help standardize grading.It can also be used as a “substitute” in some areas where there is a complete lack of pathologists today.Brother Jie: The future has come!04 Daily steps: New prognostic factors for locally advanced lung cancer?Monitoring physical activity can improve people’s health, such as observing the development of hypertension from a reduced body mass index.But you know what?A pedometer can also predict the development of a disease, but it is also cancer!A new study shows that a pedometer can predict the prognosis of lung cancer patients undergoing chemoradiation.”I think the number of steps is a new vital sign of cancer treatment! We have found that tracking the patient’s activity level before treatment can provide powerful insights for clinicians.” The researchers said.The researchers measured the activity levels of 50 patients with locally advanced non-small cell lung cancer who wore a pedometer before undergoing chemoradiation.The researchers found that the performance of patients in each group varied greatly.According to the level of patient activity, half of the inactive patients must be hospitalized during treatment, while only 9% of the more active population needs to be hospitalized.45% of inactive patients are still alive after 18 months, while more than 75% of those who are more active are still alive.”If a patient’s number of steps decreases dramatically during treatment, for example, from 5,000 steps to 2,000 steps per day, this change needs attention. Patients with a sharp reduction in steps need additional care during treatment,” the researchers said.Brother Jie: Today is the weekend. After dinner, go out and walk around ~ 05. Over 70% of oropharyngeal cancer is caused by HPV. January 3, 2020, “New England”, the first of the four major medical journalsThe Journal of the Medical Journal published a review paper on head and neck cancer.Head and neck cancer is the seventh most common cancer in the world. Head and neck cancer includes oropharyngeal cancer, laryngeal cancer, hypopharyngeal cancer, nasopharyngeal cancer, cervical esophageal cancer, and thyroid cancer.The article mentions a very important set of data: cases of oropharyngeal cancer caused by or related to HPV16 are increasing year by year, especially among young people in North America and Northern Europe, and in the United States, those diagnosed with HPV-positive oropharyngeal cancerThe proportion of head and neck cancer increased from 16.3% in the 1980s to more than 72.7% in the 2000s. These HPV-positive oropharyngeal cancers are caused by oral-sex. This also indicates that after oral contact with HPV virus, there is usually10-30 years incubation period.HPV infection can cause a variety of cancers, the most important of which is cervical cancer. 99.7% of cervical cancer is caused by HPV infection. HPV vaccine can effectively prevent cervical cancer and anal genital cancer.Fortunately, the domestic HPV vaccine developed by Xiamen University has also been approved for marketing. It is suitable for 9-45-year-old women, and the price is only 329 yuan / piece, which is much lower than the imported HPV vaccine price, which will benefit more China.crowd.Brother Jie: Plan for HPV vaccine in 2020 can be on the agenda!This week’s message: There is no shortcut or path to research or medical practice. If you choose to become a doctor or researcher, you will have to bear the weight of your life. I hope you will keep your heart.This week’s “Things about Cancer” is here.
