治疗膝骨关节炎近十年文献中特殊内服中药分析

目的:总结和分析近10年国内医学期刊公开发表的中药内服治疗膝骨关节炎的文献中特殊中药应用现状。方法:通过统一检索式,委托专业文献查新人员检索万方、维普、CNKI三大数据库,再通过纳入标准、排除标准、资料提取与文献质量评价3个环节对检索结果进行分析。并对药物分类、特殊用药前20位药物出现频次及出现百分率进行排序。结果:最终有效文献为491篇,其中出现特殊用药的文献有209篇。中药内服治疗膝骨关节炎特殊用药前20位的药物排序依次为川乌、细辛、蜈蚣、附子、土鳖虫、草乌、全蝎、半夏、胆南星、马钱子、桃仁、红花、乌梢蛇、水蛭、血竭、三七、延胡索、路路通、穿山甲、白花蛇;药物功效分类依次为祛风寒湿药、活血止痛药、活血调经药、活血疗伤药、破血消癥药、息风止痉药、发散风寒药、温里药、温化寒痰药、化瘀止血药。结论:风、寒、湿三邪可能为膝骨关节炎的主要致病外因;膝骨关节炎风寒湿痹证出现的频率可能要比热痹证出现的频率高。     

Ultrastructural Changes in Cultured Cells under the Effect of Vibrio Cholerae Hemagglutinin/Protease

Electron microscopic study of changes in cultured cells caused by Vibrio cholerae recombinant hemagglutinin/protease (HA/P) showed significant structural changes, most pronounced in HeLa and L-929 cells not forming a compact monolayer with tight junctions between the cells: formation of numerous vesicles on the cell surface and clasmatosis, vacuolation of the cytoplasm, swelling of mitochondria, clarification of their matrix and crist distortions, and increase in the number of lysosomes. Cytoplasm vacuolation predominated in MDCK culture, while clasmatosis was less intense. Addition of HA/P to CaCo2 cells forming a differentiated polarized monolayer, led to extension of cell-cell spaces not impairing tight junctions, swelling of mitochondria, cytoplasm vacuolation, and clasmatosis on the apical surface. These changes virtually completely coincided with those caused by the so-called NMDCY factor (non-membrane-damaging cytotoxin), described as new Vibrio cholerae toxin. These findings confirm our previous hypothesis about the identity of these factors.     

Morphometric characteristics of placental villi in pregnant women with diabetes

We conducted a comparative morphological study of placentas from women with gestational diabetes and diabetes mellitus. Morphometry of histological preparations revealed similar type of changes in the studied parameters of placental villi in diabetes mellitus and gestational diabetes. The maximum deviation of the studied parameters from the control was noted in type 1 diabetes mellitus.
