Traditional Chinese medicine(TCM)has played an important role in the prevention and control of coronavirus disease 2019(COvID-19)and has received considerable attention from all sectors of society.In the current situation of the global outbreak,it is crucial to promote the global application of TCM.However,the pandemic has also exposed various problems affecting the widespread acceptance of TCM.In this review,we summarize efforts to prevent and control cOoVID-19 by TCM and provide strategic guidance on how to promote its practice in the context of public health emergencies by(1)completing the system for evaluating the clinical efficacy of TCM;(2)transforming decoctions into Chinese patent medicines;(3)encouraging low-threshold traditional rehabilitation therapy;(4)strengthening communication and cooperation with the media.The aim of these approaches is to improve the rigor of TCM research and its dissemination,sharing the antiepidemic experience of TCM to the world,as well as increase the engagement of and acceptance by the masses.In this manner,TCM will not only aid in preventing and controlling CoVID-19 but can also provide tools for coping withfuture public health emergencies. 展开更多

One of the major trends in the respective research activities is the development of biotesting methods. Such methods, in addition to ecotoxicology, are highly demanded for environmental monitoring and ecological standardization. The development of biotesting in toxicology, however, is limited to the "battery of tests" paradigm, while environmental monitoring and ecological standardization are based on the "uniformity of measurements" paradigm. A "reference bioindicator" is proposed to harmonize these approaches. A reference bioindicator serves for comparison of data obtained by different bioindicators. This method was approved for the state environmental control. Application of reference bioindicators makes analytical procedure substantially cheaper. It requires, however, thorough calibration in relation to specific environmental factors (such as temperature, photoperiod etc.) as well as to specific active agents and their combinations. This problem can be solved with the start-up of calibrating analytical centers and long-term study of the effects of spatiotemporal environmental factors in specific areas and for specific reference objects. This paper demonstrates long-term study results for the surface waters of Pavlovsk reservoir (Bashkortostan, Russia). 展开更多
