OBJECTIVE:To compare the dissolubility of ambroxol hydrochloride tablets from four different manufacturers METHODS:To determine the dissolubility of ambroxol hydrochloride tablets according to Chinese WS-430(X-370)-2000 RESULTS:The accumulative dissolving quantity of all preparations exceeded 80% in 45 minutes The comparison of Weibull parameters,m,T50 and Td,showed significant differences(P

Objective To evaluate the performance of fast Treponema pallidum(TP) detection in voluntary blood donors and optimize the strategy for pre-donation screening.Methods Before blood donation,the gold standard TP test strip was used to make a fast detection.After blood donation,the TP-ELISA was used to test the blood.Then,analyze the donors′ anti-TP positive rate,times and intervals of donating,false positive and negative of TP fast detection.Results From 2014 to 2015,among 73 990 donors who were tested by using fast TP detection,0.71% of them(529 donors) were positive.Among the positive donors,89.2% of them(472 donors) were first-time blood donors.35 donors′ donating intervals were more than 3 years,who accounted for 61.4% of the donors who had donated for more than once.The numbers of the false positive obtained from fast TP detection were 5 and the false negative was 15.By applying the fast TP detection before blood donation,the rate of anti-TP positive had been declined from 0.71% to 0.17%.Conclusion The rejection rate of TP positive can be significantly reduced by using fast TP detection before blood donation.The fast TP detection can be used to optimize the pre-donation screening and promote blood donation service efficiency and level,while donating times and intervals of the blood donors were also considered.
