The structural composition of components contributes to the superiority of the geoherb Alisma orientale for “diuresis and diffusing dampness”

The purpose of this study is to explore the intrinsic reasons for the superiority of the salt-made geoherb Alisma orientale via comparing the content of various components of the salt-made geoherb Alisma orientale. The effects of “diuresis and diffusing dampness” using salt-made Alisma orientale from seven different origins were investigated through pharmacodynamic experiments in vivo and in vitro. The results indicated that salt-made Alisma orientale from different origins had diuretic efficacy; this was demonstrated by the significant increase in the volume of rat urine, the concentration of Na⁺, K⁺, and Cl⁻ in the urine, and the significant decrease in the levels of AQP-2 in rat renal medulla and HK-2 cells. It was also revealed that the diuretic effect of salt-made Alisma orientale from Fujian Province is stronger than those from other provinces. Moreover, the main components and their proportions in the salt-made Alisma orientale samples were further analyzed via principal component analysis. The results showed that alisol A 24-acetate, alisol B, and 23-acetyl alisol B are the main components of salt-made Alisma orientale, and the optimal structural ratio of alisol A 24-acetate, alisol B, and 23-acetyl alisol B was found to be 5.38 : 14.34 : 11.31 via optimizing the ratios of the three main components. It is worth noting that the optimal ratio of the three main components after optimization is the closest to the ratio of the three main components in salt-made Alisma orientale from Fujian Province. This paper reveals the “mystery” of the content ratio of the main active components and its effect on the efficacy, and showed that the proportional relationship between the content of multiple components is the key to their interactions. Therefore, this method of evaluating the quality of salt-made Alisma orientale is obviously reliable, and this study lays the foundations for quality evaluation of salt-made Alisma orientale and other herb slices.

肾缺血再灌注模型两性肾损伤差异的荟萃分析

目的 应用荟萃分析探求并评估啮齿类动物肾脏缺血再灌注模型中两性肾损伤差异.方法 检索PubMed与EMBASE数据库从2002年1月至2014年1月的相关文献,并阅读引入文献的参考文献以弥补缺漏.制定文献纳入及排除标准,并通过查阅文献制定效应指标的评价标准.采用Stata 12.0软件进行数据处理.结果 纳入14篇文献,共采用了289只动物.啮齿类动物在遭受肾脏缺血再灌注损伤后,雌性肾脏损伤程度在血肌酐[SMD=-5.95（-7.39,-4.51）,P＜0.01]、尿素氮[SMD=-3.76（-5.60,-1.93）,P＜0.01]均低于雄性.亚组分析显示,啮齿动物种类、肾脏缺血时间都会显著影响两性间肾脏损伤差异的大小;其中,缺血时间达45 min时,两性间差异达到最大.结论 啮齿动物在肾缺血再灌注后两性肾损伤程度存有差异,且缺血时间、动物种类会影响这种差异的程度.通过调整缺血时间可能会使两性损伤差异最大化.纳入的试验异质性较大且存在发表偏倚,尚需设计严谨实验.
