RESUMEN

Based on the concept of quality by design(QbD), this study optimized the processing technology of Ilicis Rotundae Cortex. According to the processing method and ingredient requirements of Ilicis Rotundae Cortex in the Chinese Pharmacopoeia, the content of syringin and pedunculoside, alcohol extract, fragmentation rate, and moisture content were taken as the critical quality attributes(CQAs). The soaking time, moistening time, and drying time were taken as critical process parameters(CPPs) by single factor tests. The weight coefficients of CQAs were determined by the analytic hierarchy process(AHP)-entropy weighting method, and the comprehensive score was calculated. With the comprehensive score as the response value, Box-Behnken design was employed to establish a mathematical model between CPPs and CQAs, and the design space for the processing of Ilicis Rotundae Cortex was built and verified. The results of ANOVA showed that the mathematical model had the P value below 0.05, the lack of fit greater than 0.05, adjusted R~2=0.910 5, and predicted R~2=0.831 0, which indicated that the proposed model had statistical significance and good prediction performance. Considering the factors in production, the best processing conditions of Ilicis Rotundae Cortex were decoction pieces of about 1 cm soaking for 1 h, moistening for 4 h, and drying at 60-70 ℃ in a blast drier for 2 h. The optimized processing technology of Ilicis Rotundae Cortex was stable and feasible, which can provide a reference for the standardized preparation and stable quality of Ilicis Rotundae Cortex.

RESUMEN

This paper was aim to optimize the purification technology of Rehmanniae Radix Praeparata extract with macroporous adsorption resin. With the content of manninotriose as index, the absorptive flow and time were investigated, as well as kinds, amount, flow of eluent. D-101 type macroporous adsorption resin was the best choice for the purification of manninotriose. The optimized parameters were as follows: the content of manninotriose at 161.16-53.72 mg x g(-1), absorption time 240 min, eluting solvent of purified water, volume flow at 1.5 BV x h(-1), and eluant volume at 6 BV. D-101 type macroporous adsorption resin could significantly increase the purity of Rehmanniae Radix Praeparata extract with the advantage of high absorption, remove most part of impurity, and the effect of semi-works production was better.

RESUMEN

PURPOSE: The goal of this study was to clarify the reporting patterns of self-reported adverse drug reactions (ADRs) in China. METHODS: A variety of sources were searched, including the official website of China FDA, the national center for ADR monitoring center, publications from PubMed, and so on. We retrieved the relevant information and made descriptive and comparative analysis from the year 2009 to 2013. RESULTS: The ADR reporting numbers were 638,996, 692,904, 852,799, 1,200,000 and 1,317,000 from 2009 to 2013, respectively. Healthcare professionals contributed significantly, and their proportion always exceeded 80% before 2012. The average report per million inhabitants has increased from 479 to 983 from 2009 to 2013. However, the proportion of new or serious report was always below 25%. The reports mainly concern anti-infective agents and traditional Chinese medicine (TCM), especially TCM injection. The proportion of ADR reports in geriatric patients has increased for 4 consecutive years. CONCLUSIONS: ADR report numbers and reporting rates in China are on the rise. However, the proportion of new or serious reports as well as the proportion of reports contributed by consumers and pharmaceutical companies are still quite low. More attention should be paid to the elderly, anti-infective agents and TCM, especially TCM injections.

RESUMEN

From the beginning of the fourth national survey of the Chinese materia medica resources, there were 22 provinces have conducted pilots. The survey teams have reported immense data, it put forward the very high request to the database system construction. In order to ensure the quality, it is necessary to check and validate the data in database system. Data validation is important methods to ensure the validity, integrity and accuracy of census data. This paper comprehensively introduce the data validation system of the fourth national survey of the Chinese materia medica resources database system, and further improve the design idea and programs of data validation. The purpose of this study is to promote the survey work smoothly.
