骨碎补化学成分和生物活性研究进展＊

骨碎补是历代临床常用中药，具有疗伤止痛、补肾强骨、消风祛斑等功效。其主要含黄酮、苯丙素、三萜、酚酸及其苷等类化学成分，现代研究表明骨碎补具有抗骨质疏松、促进骨折愈合、促软骨再生、护牙健齿、保护肾功能、抗炎、防治中毒性耳聋、降血脂等多种生物活性，开发前景广阔。本文对近年来骨碎补的化学成分、药理作用及临床应用研究进行综述，以期为骨碎补的进一步深入系统的研究和开发利用提供依据。     

The quality of spontaneous adverse drug reaction reports from the pharmacovigilance centre in western China

Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.

Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.

Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).

Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed.

刺五加水提物对人精子体外运动活力的影响

目的研究刺五加水提物对正常男性精子体外运动活力的影响，探讨其可能的作用机制。方法将20例正常男性的精子通过上游优化法处理后，一组精子加入10 mg·mL^-1的刺五加水提物，另一组加入等量的Ham’s F10培养液作对照。应用计算机辅助的精子分析系统，分别测定孵育0.5，1，2，3，4，5 h后人精子各运动参数。结果随着时间的延长，加入Ham’s F10培养液的精子活动能力有不同程度的下降；加入10 mg·mL^-1的刺五加水提物后，不同时段精子的运动能力均较对照组明显提高，精子存活率、前向运动精子百分率、曲线运动速度、直线运动速度和平均路径速度与对照组比较，均明显改善(均P＜0.05)。 结论刺五加水提物能明显提高正常男性精子的体外存活率和运动能力。
