Caricatured rumors of medical experts circulating on the Internet
Sanya Daily reporter Cai Bingxian’s attention The blue toilet block can cause cancer; corn oil and sunflower seed oil can cause cancer; chopsticks can be changed for 3 months without causing liver cancer... A shocking “health reminder†is frequently repeated on WeChat and Weibo. Is this true? Recently, experts summarized some of the more widespread cancer-related rumours circulating in the circle of friends and banned them one by one. Blue toilet block carcinogen [Proverbs]: The blue toilet block is only suitable for foreign buildings with dual water supply systems. There is almost no such water supply system in China. Since the main valve and the sub-valve do not have one-way check valves, under the influence of negative pressure, polluted water with strong carcinogenicity will flow back into the tap water system, causing dozens of cancer-related deaths. [Professor] Professor Chen Shilin, chief physician of Jiangsu Provincial Cancer Hospital, said that at present, there are no clinical cases that can prove that blue toilet blocks cause cancer. The harm of these chemical elements to the human body may still be reflected in the irritation, so it is not recommended that such substances be exposed to frequent or prolonged exposure. Gum cancer Rumor: Although the natural rubber in chewing gum is non-toxic, the white glue used in the production process is added with additives such as vulcanization accelerants and antioxidants to stimulate the stomach and cause discomfort. The sugar substitute aspartame in chewing gum is also a carcinogen. The chewing gum will contain certain additives and sugar substitute aspartame, but Zhou Junbo, director of the Department of Stomatology in the Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, explained that from the theoretical data analysis, if a person does not consume every pound, he will not There is a security risk. Corn oil, sunflower oil cooking cancer [Proverbs]: WeChat article quoted a professor Martin's point of view. He discovered that vegetable oils produce a large amount of aldehydes during cooking. The aldehydes are potentially toxic and may cause heart disease, cancer, and dementia. The professor discovered that when heated to 180 °C for a period of time, compared to sunflower oil and corn oil, butter, olive oil, and lard produced much less aldehydes, and coconut oil was the best, so he suggested not to use it. Corn oil and sunflower oil. Fry can use butter. [Prov.] Wang Dongxu, the deputy director of the Hospital of Integrated Traditional Chinese and Western Medicine in Nanjing, said that scientific and rational consumption of vegetable oil does not generally affect human health. The dietary habits of the Chinese are somewhat different from those of the West. The latter is mainly fried and fried. Chinese cooking methods include frying, steaming, stewing, braising, braising, boiling and other methods, such as frying and steaming. Generally, there will not be long-time high temperature frying. It should be pointed out that various oils are not recommended for long-term, single-use foods. It is more beneficial to replace cooking oils. Chopsticks can induce liver cancer without changing for 3 months ã€Proverbs】: After 3-6 months of use of common chopsticks, the color will change due to the attachment of food, detergent and air, and the residue in the cupboard. At this time, chopsticks will breed a variety of molds, severely moldy chopsticks will breed aflatoxin, the substance has been widely recognized to induce liver cancer. [Provoke] Liu Xin, deputy chief physician of the Department of Treatment and Treatment of Traditional Chinese and Western Medicine Hospital of Nanjing, said that wooden and bamboo chopsticks must be kept dry. If they are not moldy and clean, they do not have to be changed for 3 months. . However, if the chopsticks show signs of mildew, they must be replaced immediately. Because of moldy chopsticks, it may be contaminated with aflatoxin. Aflatoxin is a carcinogen. It is a highly toxic substance and has a destructive effect on human and animal liver tissues. When severe, it can cause liver cancer and even cause death. Wooden and bamboo chopsticks should be boiled regularly for half an hour, placed in the air to dry and then used. Try not to put the chopsticks in a confined space. Do not use a dishwashing mammoth when you wash the chopsticks. This will make the chopsticks rough, resulting in tiny grooves and cracks, leading to microbial residue. Monosodium glutamate [Proverbs]: When MSG is heated to 120°C, glutamate turns into carcinogenic pyroglutamate. Wang Dongxu said that the temperature of 100 °C heating for half an hour, only 0.3% of monosodium glutamate produced pyroglutamic acid sodium, heated for 1 hour before 0.6% of monosodium glutamate produced pyroglutamic acid sodium. Its impact on the human body is minimal. Therefore, the argument that MSG causes cancer is not reliable. For healthy people, there is no big problem with MSG, but pregnant women and infants and young children should not eat foods containing MSG. In addition, the doctor will recommend some patients with low-salt, low-sodium diet, MSG is best not to eat, sodium in monosodium glutamate, although the amount is not much, but also pay attention. No. 6 Cup Cover Cancer Rumor: Each plastic container has a triangular symbol at the bottom, similar to the "ID card," representing the plastic recycling mark. The numbers in the triangle box range from 1 to 7, corresponding to different materials. The material of the No. 6 cup lid is polystyrene, which is also identified as PS. The important point is that this plastic material will melt toxic substances at high temperatures, and it may cause cancer if it is consumed for a long time. It is recommended not to drink with a lid. The number on the plastic cup cover corresponds to the material. According to the data released by the International Cancer Research Center, the migration of styrene monomer in a hot beverage cup lid is 3.75 micrograms, while that of a cigarette is 20-48 micrograms, and cigarettes are far more dangerous than cup lids. The tentative daily maximum allowable intake of styrene formulated by International Health and FAO is 0.04 mg/kg. For people weighing 120 pounds, the maximum allowable daily intake is 2,400 micrograms. To achieve this amount of harm, it is equivalent to drinking about 107 cups of hot drinks each day. Medicine Peptides and protein drugs are emerging. There are now 35 important therapeutics on the market, and the development of biotechnology and biopharmaceutical companies is becoming increasingly global. Biotechnology drug research focuses on the application of DNA recombinant technology to develop peptides, proteins, enzymes, hormones, vaccines, cell growth factors and monoclonal antibodies that can be used in clinical applications. According to Parexl's Pharmaceutical R&D Statistical Source Book, there are currently 723 biotech drugs under FDA review (including phase â…° to iii clinical and FDA evaluation), 700 drugs are in early stage (research and preclinical). More than 200 additional drugs are in the final stage of approval (Phase iii clinical and FDA evaluation). The basic dosage form of biotech drugs is lyophilized. Although the efficacy of conventional preparations has long been clinically proven, they need to be injected frequently for a long time due to their short half-life, which is difficult to accept from the perspective of psychological and economic burden on patients. To this end, scholars around the world mainly from two aspects to study and develop convenient and reasonable drug delivery approaches and new preparations: (1) embedment agent and sustained-release injection. â‘¡ Non-injectable dosage forms, such as respiratory inhalation, rectal administration, nasal administration, oral administration and transdermal administration, etc. Injectable preparations of sustained-release biotechnological drugs are new dosage forms with promising applications. Some of them, such as microsphere injections of luteinizing hormone releasing hormone (LHRH) analogues which can be sustained-release for 1 to 3 months, have been on the market. This paper focuses on this kind of preparations.Main types of peptides and protein drug sustained-release preparations The research and development of peptides and protein drug sustained-release preparations can be divided into two types, namely, embedment agent and microsphere injection, from the perspective of development process and dosage form. The shape of the implant is a hollow micro-fine rod, one end is closed, the other end is open, and the rod material is non-biodegradable polymer such as ptfe. The lumen was filled with a mixture of drugs and silica gel (silastic, polydimethylsiloxane). The implant is embedded under the skin, and the drug is released slowly through the opening of silica gel matrix. The American Physicians' Handbook (PDR) contains a product called Norplant? Levo-18 ethyl norethinnes, used in family planning. The preparation, each with a diameter of 2.4 mm and a length of 34 mm, is surgically implanted in the inner side of the patient's upper arm with 6 thin rods. The drug can be released in the body in zero-grade mode for up to 5 years, and then removed by surgery after release,1.1.2 Micro-osmotic pump embedding agent The United States Alza company in the 1970s developed an embedding agent shaped like a capsule, which is embedded in the skin or other parts. The body fluid can penetrate through the shell, dissolve the interlayer electrolytic layer, make the volume expansion of the interlayer pressure to the plastic inner cavity, and promote the drug solution from the opening of the fixed speed release. Many biomolecular drugs, such as insulin, heparin and nerve growth factor, have been reported as model drugs in vivo and in vitro. Implants have positive significance for the treatment of chronic patients who need long-term medication, but it has the following defects: â‘ must be surgically implanted. â‘¡ The skeleton material of the preparation is non-biodegradable polymer, which needs to be removed by surgery after release. â‘¢ The preparation has irritation and discomfort in local tissues. Evaluation methods for polypeptide protein drugs: 1. Liquid chromatography 2. Spectroscopic 3. Solvent-based versions are easy to use, but need to be kept at low temperatures (2-8 degrees Celsius). medicine peptides high,Peptide injections,buy medicine peptides high,medicine peptides for bodybuilding,medicine peptides for hgh Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropic.com
