Sky-high winter worm summer grass is not anti-cancer? Experts: Whether cancer is not related to herb.

Whether the winter worm summer grass can fight cancer has become "Roshengmen" (above
Wang Chengshu, a researcher at the Shanghai Institute of Plant Physiology and Ecology of the Chinese Academy of Sciences, recently cried and laughed.
not long ago, his team published a study in the international academic journal Cell Chemical Biology that found that weeds and squirts were synthesized at the same time in aphid grasses, which do not have the genes to synthesize pyrethrins and sedentines.
was supposed to be a happy news for scientific progress, but unexpectedly, the results of this research was misread by many media as the winter worm summer grass does not fight cancer.
winter worm summer grass must contain insect grass
The winter worm summer grass, which appeared in Wang Chengshu's research, is a highly sought after Chinese herbal medicine.
, in an ordinary tea shop in Beijing, the better quality of winter worm summer grass, the unit price of 370 yuan per g, per kg of 370,000 yuan. The price of a queer of gold is only a few hundred yuan.
"It moisturizes the lungs, is good for the kidneys, and also enhances immunity and fights tumors." The salesman in this shop introduced the winter worm summer grass in this way. The salesman's words are not without basis. Medical ancient books have long been recorded for winter worm summer grass. "The Pharmacopoeia of the People's Republic of China" records the winter worm summer grass: "to replenish the kidneys and lungs, hemostic sputum." Used for renal failure, impotence sperm, back and knee soreness, long cough wheezing, hard coughing healing. "
but there is no "anti-tumor" in Chinese medicine, people believe that the winter worm summer grass has anti-cancer effect, to some extent, it is believed that it contains worm grass.
oxytocin, or 3'-deoxygenate, was first discovered by German scientists in aphid grass in 1950, and subsequent studies have shown that it has antibacterial, insect and anti-cancer biological activity. The U.S. Food and Drug Administration (FDA) approved a clinical trial of pyrethrin for leukemia in 2007, although it is not yet a drug.
, the content and content of insect grasses are often regarded by ordinary people as an important indicator to measure the quality of insect grasses.
the most valuable of the hundreds of species of insect grass, winter worm summer grass containing insect grass seems to be a matter of course. Merchants also often to insect grass to promote the efficacy of winter worm summer grass, Taobao online a winter worm summer grass capsule products will be labeled as one of the main parts.
this natural "hypothesis" has been repeatedly questioned. In 2014, wang Hai, a well-known counterfeiter, reported that he had purchased the famous winter worm summer grass containing tablets of the product "extreme grass", the detection found no insect grass.
academic research, nor does it provide a basis for this "hypothesis".
't it anti-cancer if it doesn't contain
?"Winter worm summer grass is not containing insect grass, or the content of worm grass is very low, is already recognized in academia." Li Yuling, director of the Winter Worm Summer Grass Research Office of Qinghai Academy of Livestock and Veterinary Sciences, told Science and Technology Daily.
Li Shaoping, deputy director of the National Key Laboratory for Chinese Medicine Quality Research at the University of Macau, told reporters that as early as 2006, his team had written in the international journal Journal of Analytical Chemistry that winter worm summer grasses did not contain conventional high-efficiency liquid chromatography methods to detect insect herb, which has been reported in the past from natural and artificial winter worm summer grass detected by improper detection methods.
" nest-forming penicillin can also be synthesized with herb, and the mold is widely found in nature. So if we can detect the worm grass from the winter worm summer grass collected in the wild, it means that there is a problem of mold contamination. Wang Chengshu explained to reporters.
Li Shaoping, wang Chengshu research team's focus of this discovery is to clarify the biosynthetic pathway and related genes of insect grass.
reporters learned that since 2011, Wang Chengshu research team has completed the study of the genome of 18 species of insect grass, such as aphid grass, winter worm summer grass and grass flower. On this basis, they uncovered the synthesis mechanism of the worm grass: the worm grass and the spray serotonin are synthesized by the same gene cluster, which acts as the "protector" of the structural stability of the worm grass. More strikingly, the study also found that the cluster of genes was not included in the winter worm's summer grass.
, 2017, the results of the study were published in an international journal under the title "Aphids in Fungi and Their Protective Molecular Sprays."
" previously from the point of view of chemical testing that winter worm summer grass does not contain insect grass, some people do not believe. Now genome sequencing has found that there are no genes to synthesize it. Wang Chengshu said in an interview with Science and Technology Daily.
soon, the result was interpreted as "winter worm summer grass is confirmed not to be cancer-resistant at all".
" Mr. Wang's research results from a scientific point of view, no problem. But the active ingredient of winter worm summer grass is not only insect grass. According to Liu Aizhong, a researcher at the Institute of Microbiology of the Chinese Academy of Sciences, winter worm summer grass does not contain insect grass, and does not mean that winter worm summer grass is not anti-cancer.
Li Yuling holds a similar view. Both scholars agree that winter worm summer grass may also contain other anti-cancer ingredients, but this is not clear.
"the exact saying is that 'winter worm summer grasses do not contain known anti-cancer ingredients'." Wang Chengshu said that the study only from a biological point of view to confirm that the winter worm summer grass does not contain insect grass and spray stodging only, did not draw a conclusion on whether the winter worm summer grass is cancer-resistant.
whether the fight against cancer has nothing to do with insect grass
Li Yuling, who studies the biology of winter worm summer grass, prefers to look at the efficacy of winter worm summer grass from the perspective of Traditional Chinese medicine.
"Winter worm summer grass is a kind of Chinese medicine, we can not err on the basis of the principle of the role of Western medicine, must be parsed to one of its genes or corresponding target, in order to think it has an effect." Li Yuling said.
Li Yuling believes that from the ancient records and modern scientific research, winter worm summer grass does have a very good effect, but there is no way to explain from a pharmacological point of view, its specific target of each component is exactly what.
ancient books only recorded the other effects of winter worm summer grass, as to whether it has anti-tumor effect, can only be judged by modern scientific experiments.
Li Shao equal published in 2001 paper "Winter worm summer grass anti-tumor effect research progress", winter worm summer grass anti-tumor effect reported in the 1960s, a series of subsequent studies show that "winter worm summer grass does have anti-tumor effect."
paper cites a variety of studies on the anti-tumor activity of winter worm summer grass. For example, it was found that the winter worm summer grass alcohol was significantly inhibited for ai's astrophalt cancer in mice, and the effect was significantly positively correlating with the dose.
addition, the winter worm summer grass contains insect grass polysaccharides, etc. have significantly improved the body's immunity. " Li Shaoping said that modern research shows that immunity is closely related to cancer, and immunotherapy has become an important method and research focus for cancer treatment.
there is still controversy in academia about whether winter worm summer grass is cancer-resistant. An industry expert, who did not want to be named, said that at most this stage of the study can only prove that the winter worm summer grass in the anti-tumor cell activity, can not directly draw a conclusion "winter worm summer grass anti-cancer."
left more unknowns for researchers. Wang Chengshu told reporters that the team found more than 20 possible clusters of genes that could synthesize active substances in the genome of the winter worm summer grass, but its genetic function is unknown.
"but it can be confirmed that whether or not the winter worm summer grass is cancer-resistant, it has nothing to do with the worm grass." Li Shaoping said.
