Introduction: Pfizer CEO tested positive for the new coronavirus for the second time! herpes virus "transformed" the cancer nemesis! my country's first domestic proton therapy system was approved for market... Biological Exploration will pay attention to the "medicine" news and explore the value of biotechnology!
01 Pfizer CEO tested positive for the second time
new coronavirus
Pfizer CEO Albert Bourla said on Twitter on Saturday (September 24) that his coronavirus test was positive but showed no symptoms: "My new coronavirus test was positive. I feel good and there are no symptoms. I haven't taken the new bivalent enhancer yet because I have been waiting for 3 months as per the CDC's guidelines since my last new coronavirus in mid-August. Although we have made a lot of progress, the virus still exists." He tweeted on Saturday.
Bourla has currently received four rounds of Pfizer vaccine. According to Reuters , he tested positive for the new coronavirus for the first time on August 15. At the time, Bourla, 60, said he was in quarantine and began treatment for the company's oral COVID-19 antiviral treatment drug Paxlovid.
CDC says people infected with the new coronavirus should postpone the vaccination of boosters because the infection provides some immunity: "Think about postponing your vaccine for 3 months from the beginning of your symptoms, or, if you have no symptoms, postpone the vaccination when you are tested positive."
02 Use poison to fight poison!
Herpes virus "transformed" cancer nemesis
Science and Technology Daily reported on September 26 that British scientists submitted a paper at the recently held European Society of Oncology Medicine (ESMO) in 2022, saying that their results show that a genetically modified herpes virus may bring hope to cancer patients who have exhausted all other therapies: it showed significant efficacy in a trial with 39 patients participating.
Researchers pointed out that this virus, called RP2, is a genetically modified herpes simplex virus that deals with advanced cancer through "serial attacks": first destroying their cells, and then letting the immune system work. The results showed that the tumors in the three patients who received RP2 were reduced in size, among which the tumors in the salivary cancer and patients disappeared completely, and the cancer did not recur after 15 months. The cancer in the other two patients with esophageal and uveal melanoma has shrunk. Of the seven beneficiaries who received combination therapy, six of the cancer did not worsen over 14 months. In addition, most of the side effects reported by patients are fever, chills and fatigue, without medical intervention.
The research director Kevin Harrington said: "Our preliminary trial results show that for some patients with advanced cancer, , including those who do not respond to other forms of immunotherapy, this transgenic herpes virus may become a new treatment option."
03 The first domestic proton therapy
system was approved for the market
0 September 26, 2022, National Medical Products Administration approved the registration application for the innovative product of "proton therapy system" produced by Shanghai Aipqiang Particle Equipment Co., Ltd. This product is a key support project for the "Digital Diagnosis and Treatment Equipment Special Project" key R&D plan of the Ministry of Science and Technology during the 13th Five-Year Plan period, and is also the first domestically produced proton therapy system approved for market launch in my country. The approval of this product marks another step in the localization of high-end medical equipment in my country, and is of great significance to improving the diagnosis and treatment methods and levels of medical tumors in my country.
This product consists of two parts: accelerator system and treatment system. The accelerator system includes an injector system, a low-energy transmission system, a main accelerator system, a high-energy beam current transmission system and an auxiliary electrical system. The treatment system includes a fixed beam therapy system, a 180° rotating beam therapy system and a treatment planning system. The product provides proton beam for radiation therapy. While achieving high doses in the tumor site, it can reduce the dose of surrounding normal tissue, especially the dose of tissue behind the target area. It is suitable for the treatment of systemic solid malignant tumors and certain benign diseases. The specific indications should be determined by the clinician based on actual conditions.
04 Uganda Ebola epidemic has killed 23 people
Intern doctors strike
According to the BBC report on September 27, after the Ebola outbreak in Uganda , intern doctors who fought against Ebola in Mubend Regional Hospital decided to strike, and they accused the government of putting their lives at risk.
An intern at the hospital who asked not to be named said: "For the most part, you are touching the patient with bare hands." All interns at the Mubend Regional Hospital said they are on strike and demanding a move to a safer place.
A spokesman for the Uganda Ministry of Health said, "The hospital did not strike." However, all 34 interns at the hospital - including doctors, pharmacists and nurses - have announced the strike decision in a joint statement. They say they are at inappropriate risk because they lack safety equipment, risk allowances and health insurance. Six interns at the hospital have been exposed to Ebola virus and are waiting for test results in quarantine.
On September 20 this year, after Ebola cases appeared in a village in Madudu County, Mubend District, central Uganda, Uganda's health authorities announced an outbreak of Ebola virus caused by the Sudan Ebola strain. The first case was a 24-year-old man who and six of his family members had died. Official Uganda government data shows that 36 people have been suspected of being infected with Ebola, and 23 of them have died.
05 Chengdu girls of appropriate age can receive domestic HPV vaccine for free
According to the official website of Chengdu Health Commission on the 26th, in September 2022, Chengdu Municipal Health Commission , Municipal Education Bureau, and Municipal Finance Bureau revised the "Implementation Plan for Comprehensive Prevention and Control of Cervical Cancer in Chengdu". In addition to still following the principle of "informed consent, independent selection, voluntary vaccination" and adhering to the subsidy standard of 600 yuan per person, Chengdu will also include the newly launched domestic bivalent HPV vaccine "Wozehui" in the project vaccine. Choosing this vaccine will achieve free vaccines and benefit more girls of appropriate age at school.
