Introduction: A new recombinant swine influenza virus was discovered in my country; Monkeypox is accelerating its evolution and the transmission rate is increasing; counter-seasonal influenza is related to the new coronavirus epidemic... BioExploration will pay attention to the "drug" news with you and explore the value of biotechnology!

01 A new recombinant swine influenza virus was discovered in my country

Recently, the School of Public Health of the University of Hong Kong published a research article, which found that H9N2 avian influenza virus is infecting pigs in China and is recombining with swine influenza virus , suggesting the need for China and other regions to continue Surveillance for swine influenza viruses. In addition, studies have found that the avian influenza A virus associated with human infection contains internal genes derived from avian H9N2 viruses, indicating that internal genes of H9N2 viruses may contribute to zoonosis transmission.

02 The evolution of monkeypox is accelerating, and the transmission rate is increasing.

On June 24, a study published on Nature Medicine pointed out that the virus strain related to the monkeypox epidemic discovered in May has recently continued to mutate and evolve during human-to-human transmission. This may be Explain why the transmission rate of the virus is increasing. Researchers reconstructed the genome sequence of the monkeypox virus related to this epidemic and found that the monkeypox virus that appeared this year differed from the closely related viruses in 2018-2019 by about 50 single nucleotide polymorphisms , which is far more than The general level of virus mutation. Researchers believe that this change indicates that virus mutation is still accelerating.

In addition, according to recent reports, monkeypox has entered Asia. Singapore, , and South Korea have recently discovered cases one after another. The first confirmed case of monkeypox has also been discovered in Taiwan.

03 Off-season influenza is related to the new crown epidemic

Recently, according to the "Influenza Surveillance Weekly Report" released by the "China National Influenza Center", from late April to mid-June, the number of influenza-like cases reported by hospitals in southern provinces continued to rise, rapidly exceeding previous years. levels and still maintains an upward momentum. Fujian, Guangdong, Guangxi, Henan, Jiangxi and other provinces have successively issued summer influenza warnings.

Virology expert Dr. Chang Rongshan believes that new crown prevention and control has reduced the public’s contact with respiratory pathogens, herd immunity is weaker than before, and my country’s sluggish influenza vaccine vaccination rate is even worse, which is leading to important cause of this influenza outbreak. He believes that in addition to strengthening the vaccination of influenza vaccines, after the new coronavirus epidemic is over in the future, a series of physical epidemic prevention measures such as wearing masks and social isolation should be canceled as soon as possible during the non-epidemic season. He said that excessive protection will continue to damage herd immunity. It may lead to more unexpected diseases in the future.

04 Nurses will have the right to prescribe

On the afternoon of June 23, the 10th meeting of the Standing Committee of the 7th Shenzhen Municipal People's Congress voted and approved the revised version of the "Shenzhen Special Economic Zone Medical Regulations" (hereinafter referred to as the "Medical Regulations"). The country’s first local medical regulations were completed. Article 64 of the revised "Medical Regulations" stipulates that nurses who have obtained a specialist nurse certificate can carry out the following practice activities in nursing specialist outpatient clinics or community health service institutions: (1) Issuing examination application forms, treatment application forms, etc.; 2) Prescribe topical drugs. This provision means that "specialist nurses will enjoy certain prescribing rights." This is not only one of the highlights of the newly revised "Medical Regulations", but it is also regarded as a national pioneering measure and has attracted the attention of the national medical community.

American scientists discovered 2 centimeter-long bacteria

On June 24, a research team composed of Lawrence Berkeley National Laboratory and other institutions in the United States published an article in the magazine " Science " saying that they had discovered giant bacteria with a maximum length of 2 centimeters. Usually bacteria are only about 1/500 millimeter in length, and the team said this discovery "subverts the traditional concept of bacteria." The scientific research team discovered a filamentous organism attached to fallen leaves in a mangrove forest in the French Overseas Department of Guadeloupe in the Caribbean. After analyzing it with an electron microscope, it was discovered that the DNA exists in the cells of organisms and has bacterial characteristics.Researchers say that the longer the bacteria, the easier it is for the cells that make up the bacteria to obtain oxygen and sulfur compounds.
