Rat estradiol (E2) instruction manual.doc What is "super bacteria"? He Xiong, deputy director of the Beijing Center for Disease Control and Prevention, recently wrote that "super bacteria" are actually multi-drug resistant bacteria. This is not a new topic. The NDM-1 that appeared this time is a gene that will change bacteria and make They are resistant to most antibiotics. It is actually a genetic change of an enzyme, which is easily mixed with bacteria and becomes a carrier of bacteria, which can be copied and spread. Super bacteria can "copy" Cai Haodong, an infectious disease expert at Beijing Ditan Hospital, also mentioned in the article that there is a genetic unit like "removable hard disk" among the genetic genes of bacteria called "integrons", which can "copy" some other things from other bacteria. "Trojan virus" resistance genes "integrate" into their own genes, so that they can obtain the "code" to "break" the activity of antimicrobial drugs, resulting in drug resistance; it can not only treat this drug-resistant "Trojan virus" "The genes are passed on to the next generation, and can even be passed to the same or different kinds of bacteria around them, so that they all gain the ability to resist drugs. "Superbugs" mainly occur in hospitals Due to frequent international air travel, globalization, and the rise of medical tourism in South Asian countries, NDM-1 now has the opportunity to quickly spread to any corner of the world. However, this bacterial infection will not cause the epidemic in the general population like avian influenza and SARS. They mainly occur in hospitals, especially in surgical patients. Their resistance is reduced due to injuries, diseases and drugs. More importantly, they often use many antibacterial drugs. This makes the “super germs†that are not afraid of antimicrobial drugs invade, causing patients to become infected. "Super germs" is a warning for humans to abuse antibiotics The emergence of "super bacteria" is the result of human antibiotic abuse. Since the invention of antibiotics by humans, there has been a constant game between microorganisms such as bacteria and antibiotics. Especially as the production cost of high-end antibiotics decreases and the population of users rapidly increases, the emergence of drug resistance in bacteria is becoming a global problem. A few decades ago, penicillin was the best antibiotic for human beings. Patients with colds, fever, etc. had an immediate effect with a shot. But for the same disease now, the use of penicillin in the past dozens of times is not necessarily effective. Even for the new generation antibiotics of cephalosporins and levofloxacin developed in the past 10 years, the resistance of bacteria is as high as 30% -50%. How to deal with "superbugs"? The way to deal with this "superbug" is mainly to control nosocomial infections. Wu Qi, the dean of Haihe Hospital, pointed out: Medical staff should pay attention not to abuse antibacterial drugs, pay attention to disinfection and isolation in various operations in the hospital, wash hands frequently, and perform aseptic operation; in particular, pay attention to identifying cases of NDM-1 bacterial infection. Patients who have undergone surgical treatment abroad should pay special attention to screening for NDM-1 bacteria after infection, isolate patients in time, and prevent cross-infection and spread of NDM-1 bacteria in hospitals. Expert recommendation: establish a continuous monitoring system for bacteria and strictly manage the use of antibiotics Liu Qiyong, a researcher at the Institute for Infectious Disease Control and Prevention of the Chinese Center for Disease Control and Prevention, suggested that the government should take guiding measures, such as requiring doctors to prescribe prescriptions without using antibiotics. If they must be used, they must propose clinical indicators. During the process, try to leave room as much as possible. In addition, drug sales must be strictly controlled, and pharmacies must look at prescriptions when selling antibiotics. At the same time, it is reminded to pay attention to the use of veterinary drugs. For example, antibiotics should be used according to regulations. Many bacteria are zoonotic, such as tuberculosis. Many animals can also be infected with tuberculosis and bacteria. Strengthening monitoring and unifying planning guidance are very important measures. Establishing a monitoring network for antibiotic and bacterial resistance will help to scientifically and consciously track its resistance. If some bacteria have become resistant, can we consciously suspend certain antibiotics first? After a period of time, the sensitivity of the bacteria to this antibiotic will be restored. Hotel furniture refers to various types of furniture used in hotels, including hotel room furniture, public area furniture, restaurant furniture, etc. According to different functions and usage locations, hotel furniture can be divided into the following categories: Business Chair,Leisure Chairs,Dining Chairs,Banquet Chair Foshan Shengshi Zhihui Technology Co., Ltd. , https://www.szhfurniture.com
On August 11, a paper from the authoritative medical journal "The Lancet" caused a lot of waves around the world. On the 18th, a seminar on "super bacteria" was held in the Ministry of Health. Experts at the meeting said that "super bacteria" is an infection, not an infectious disease, so everyone does not have to panic. At present, no trace of "super bacteria" has been found in our mainland.
1. Hotel room furniture: Hotel room furniture refers to various furniture used in hotel rooms, including beds, bedside tables, wardrobes, desks, dressing tables, chairs, etc. The design of guest room furniture should focus on comfort and practicality, while also considering aesthetics and environmental friendliness. The material of guest room furniture is usually high-quality wood or board, and finely processed and decorated to enhance the comfort and luxury of the guest room.
2. Public area furniture: Public area furniture refers to various furniture used in hotel public areas, including lobby furniture, conference room furniture, rest area furniture, etc. The design of furniture in public areas should focus on practicality and aesthetics, while also considering pedestrian flow and functional requirements. Durable materials such as metal, glass, and leather are usually chosen for furniture in public areas to improve its lifespan and wear resistance.
3. Restaurant furniture: Restaurant furniture refers to various furniture used in hotel restaurants, including dining tables, chairs, bars, wine cabinets, etc. The design of restaurant furniture should focus on comfort and aesthetics, while also considering the style and atmosphere of the restaurant. Restaurant furniture is usually made of durable materials such as solid wood, stainless steel, and plastic for easy cleaning and maintenance.
Overall, the classification of hotel furniture is based on its function and place of use. Different types of hotel furniture vary in design, material selection, and manufacturing techniques, but they all emphasize comfort, practicality, and aesthetics. The selection of hotel furniture should be based on the hotel's style and needs to enhance customer satisfaction and the hotel's image.
