ABSTRACT
Since the outbreak of COVID-19 in Wuhan, China, at the end of 2019, it has demonstrated China′s ability to identify unknown pathogens. At present, reports showed that the main transmission routes are respiratory droplets and indirect contact, other vertical transmission routes have yet to be confirmed. This review discusses the possible transmission routes of 2019-novel coronavirus (2019-nCoV), based on currently research, the main transmission routes are respiratory droplets and indirect contact, fecal-oral might bepossible, while aerosol, tear (conjunctival) and mother-to-fetus still have yet to be confirmed, providing a reference basis for 2019-nCoV prevention and control and public protection.
ABSTRACT
The views from teachers and residents were analyzed to discusses the problems existing in the standardized training of TCM residents,and try to find the solution.A total of 98 standardized training residents and 111 teachers from Dongfang Hospital affiliated to Beijing University of Chinese Medicine (BUCM) were enrolled.The questionnaire sceened by star APP on the phone was used to investigate them with six practical questions,each of which had three options.Both groups agreed that undergraduates' rotate period for 3 years,masters' period for 2 years,and doctors' period for 1 year.As to the item of TCM hospital selection,both groups chose traditional Chinese medicine hospital for resident standardization training.As to the item of majors,59 teachers (53.2％) and 67 (68.4％) residents chose to learn their majors.The teachers suggested that student independent management can improve sense of presence in the department.But 36.7％ of residents considered increasing income can improve sense of presence.There are some problems in TCM residents training system,and we suggest that it should be proceeding from reality in residents and constantly improved in the future.
ABSTRACT
OBJECTIVE: To explore the mechanism of the inhibiting effects of recipe for dispersing stagnated liver qi to promote bile flow (Danshijing Tablets) on cholesterol gallstone formation and provide experimental evidence for its clinical application. METHODS: Eighty guinea pigs were randomly divided into 4 groups, which were normal control group, untreated group, ursodeoxycholic acid (UDCA)-treated group and Danshijing Tablets-treated group. The gallstones in guinea pigs were induced by high-cholesterol diet. UDCA and Danshijing Tablets were given orally to guinea pigs in the corresponding group respectively for seven weeks. Then the physical signs of the guinea pigs, the rates of gallstone formation and the histomorphological changes of the gallbladder were examined. RESULTS: The behavior of guinea pigs in the Danshijing Tablets-treated group was obviously improved and the rate of gallstone formation was significantly decreased as compared with those in both untreated and UDCA-treated groups (P<0.05). The inflammation reaction of mucous membrane in gallbladder was evidently reduced in the Danshijing Tablets-treated group and its morphological appearance turned to be approximately normal. CONCLUSION: Recipe for dispersing stagnated liver qi to promote bile flow may decrease gallstone formation. Its mechanism may be related to reducing pathologic changes in gallbladder tissues, which will reduce the damages of cholesterol to the smooth muscle in gallbladder and enhance the contractility of gallbladder.
