绞股蓝总甙复合国产1号避孕片对健康妇女脂类代谢及血压的影响

本研究将180名已婚、一孩、年龄33±5岁,需要使用避孕措施的健康妇女随机分成6组,即IUD组、绞股蓝总甙加IUD组、1号OC片组、40mg、60mg、80mg绞股蓝总甙分别与1号OC片复合的3个试验组.用双盲法给药,连续服用6个月观察脂类代谢和血压的变化.结果显示:以IUD组和1号OC片组的数据为参比值.服用不同剂量绞股蓝总甙复合口服避孕药后无升高TG和TC的趋势,有显著升高HDL-C作用和使APOA_1水平上升的趋势;亦存在降低收缩压的趋势,对舒张压无明显影响,但在服药后3个月时HDL-C水平曾发生暂时性下降.

“抑肝纤”对大鼠实验免疫损伤性肝纤维化阻断作用的研究

目的本研究利用人血白蛋白免疫损伤Ｗｉｓｔｅｒ大鼠造成肝纤维化模型，以观察“抑肝纤”对大鼠肝纤维化的阻断作用。方法将不同浓度中药“抑肝纤”用于治疗组并与模型组和对照组进行对比，综合分析血清肝纤维化指标、肝组织病理改变、肝组织胶原纤维和网状纤维病理图像定量分析等结果。结果治疗组血清肝纤维化指标（ＰＣⅢ、ＨＡ、ＬＮ）均低于模型组，接近正常组，差异有显著性（Ｐ＜０．００１或Ｐ＜０．０５）。光镜下肝组织病理变化，肝组织中胶原纤维和网状纤维病理图像定量分析结果治疗组优与模型组，尤以低浓度组更为明显（Ｐ＜０．００５或Ｐ＜０．０５）。结论研究结果表明，中药“抑肝纤”如能早期应用，可有效地阻断或延缓实验鼠肝纤维化的发生     

药用植物濒危与保护等级划分中的问题及其标准探讨

保护珍稀濒危药用植物是中医药学持续发展的前提。从物种濒危与保护等级划分的现状出发,对药用植物濒危与保护等级划分中存在的问题进行了分析。指出药用植物濒危等级划分应参照IUCN国际标准进行,保护等级划分应针对药用植物特点采用定性定量相结合的方法,并对相关的定性、定量指标进行探讨,为珍稀濒危药用植物保护等级划分提供参考依据。     

No genotoxic effect of propofol in chinese hamster ovary cells: analysis by sister chromatid exchanges

BACKGROUND: In spite of its high placental transfer, propofol is frequently used in general anesthesia and sedation during obstetric and gynecological surgery such as in vitro fertilization. This study investigated whether or not propofol has a genotoxic potential by the sister chromatid exchange assay in vitro. METHODS: Sister chromatid exchanges induced after exposure to propofol were measured in Chinese hamster ovary cells with and without metabolic activation. After propofol (0.2-20 microg ml(-1)) diluted dimethyl sulfoxide was applied for 2 h with or without S9 mix, the cells having been incubated for two metaphases (34 h) in the presence of 5'-bromo-2-deoxyuridine. N-nitrosodimethylamine and mitomycin C were used as positive controls with and without metabolic activation. The chromosomes were stained with the fluorescence plus Giemsa method, and then sister chromatid exchanges in 50 cells were counted for each concentration. RESULTS: Although increasing concentrations of propofol inhibited cell proliferation, no concentrations of propofol used in this study increased the sister chromatid exchange values, with and without metabolic activation. CONCLUSION: It was concluded that there was no indication, from the sister chromatid exchange assay in mammalian cells, of a genotoxic effect of propofol and its metabolites.

Video-fluoroscopic study of swallowing in children with neurodevelopmental disorders

BACKGROUND: Children with neurodevelopmental disorders can have feeding problems. Malnutrition and recurrent aspiration pneumonia can increase the risk of morbidity and mortality. Video-fluoroscopic study of swallowing (VFSS) is essential in understanding the pathological mechanisms involved during swallowing. METHODS: The aim of the present study was to assess the role of VFSS in assessment and management of four children with various neurodevelopmental disorders in a multidisciplinary feeding team. We describe the team approach, with the participation of child neurologist, radiologist with the rehabilitation team including the speech therapist, occupational therapist and dietician, in the assessment and plan of management. RESULTS: Video-fluoroscopic study of swallowing had been useful in assessing the type of swallowing problems with treatment goals targeted to the basic underlying pathophysiological mechanism. CONCLUSION: A child neurologist should be involved in the multidisciplinary oromotor rehabilitation program for neurologically impaired children with feeding problems.
