Effects and Interactions of Prostaglandins and Interferon-γ on Steroidogenesis of Human Luteal Cells

Previous work from our laboratory has demonstrated that T lymphocyte-derived cytokine, interferon-gamma (IFN-γ) may play a role in human luteal regression by inhibiting luteal progesterone production. Prostaglandin F2a has been known as an important luteolytic factor in a wide range of mammalian species. It was of interest to investigate the effects of IFN-γ on prostaglandin synthesis and their possible interaction with the inhibition on human luteal steroidogenesis. Human luteal cells were cultured for four days in the presence or absence of IFN-γ. Simultaneously, the productions of progesterone, prostaglandin F2a ( PGF2a ), prostaglandin E2 ( PGE2 ), and 6-ketoprostaglandin F1a(PGF1a) were evaluated. Concomitant with the inhibition of progesterone production induced by IFN-γ, a biphasic pattern of response of. prostaglandin synthesis was observed, i.e. a slight decrease of PGF2a and PGF1a after a 48 h exposure to IFN-γ while an increase of PGE2 after 96 h. In a separate experiment, a luteotropic action of PGE2 and PGF2a on human luteal cells from different stages was observed during 48 and 96 h periods of culture. In addition, while indomethacin (INDO) treatment markedly blocked the prostaglandin synthesis, the basal as well as hCG stimulated progesterone production was still inhibited by IFN-γ as usual. These results suggested that prostaglandins appeared to be not responsible for the observed inhibition of progesterone production since the inhibitory effect was not influenced by concurrent treatment with INDO which suppressed prostaglandin synthesis,     

肝火证、肝胆湿热证的病理生理学基础研究

对７０例肝火证，８７例肝胆湿热证患者进行不同层次多项指标的实验研究。结果发现：此两证患者机体均处于应激状态；炎症介质释放增加；调节血管平滑肌以舒血管活性物质增多占优势。肝火证以内源性内分泌失调机能代谢偏亢为主；而肝胆湿热证以外源性炎症反应，脂质过氧化自由基损伤为明显。

美托洛尔对高血压病人左室肥厚和心功能的影响

对３０例原发性高血压病合并左室肥厚患者用美托洛尔降压治疗２月，应用超声心动图观察左心结构和心功能的变化．结果：１）服药２月后血压明显降低（Ｐ＜０００１），显效率８０％，６９％的病人血压完全降至正常；２）服药后ＩＶＳＴ和ＰＷＴ均显著降低，各平均降低１２４％（Ｐ＜０００１）和４１％（Ｐ＜００５）．ＬＶＭＩ降低１０６％（Ｐ＜０００１）．ＡＯＤ，ＬＡＤ，ＬＶＥＳＤ及ＬＶＥＤＤ无显著改变．多因素相关分析显示ＬＶＭＩ下降值与血压下降无关．３）服药后左室舒张功能指标Ｅｐ，Ｅｐ／Ａｐ及Ｅａｆ显著增加，而Ａａｆ和Ａａ／Ｅａ显著降低（Ｐ＜００１）．多元逐步回归分析显示左室舒张功能指标改善主要受血压下降，室壁减薄及ＬＶＭＩ降低影响，ＨＲ下降也起一定作用．左室收缩功能指标ＥＦ，ＦＳ及ＰＥＰ／ＥＴ无显著改变，ＣＯ下降１０８％（Ｐ＜００２）．表明：美托洛尔是一种安全有效的抗高血压药，降压时对ＬＶＨ有消退作用，同时对异常的舒张功能有改善作用，对收缩功能没有明显的损害作用

Recurrence of chronic subdural hematoma after trepanation and drainage

Objective: To sum up the causes of recurrence of chronic subdural hematoma (CSDH) from failure of trepanation and drainage and explore its prevention and treatment. Methods- From October 1988 to June 2002 a total of 358 patients with CSDH were treated with trepanation and drainage in our hospital. Among them 15 patients had recurrence of CSDH after operation. The data of the 15 patients were reviewed retrospectively. Results: Of the 15 patients, 13 were cured by retrepanation and redrainage, one cured by removal of hematoma by craniotomy with bone flap, and one, a 1-year old child, gave up reoperation due to severe encephalatrophy. Conclusions: Most CSDHs which recur after trepanation and drainage can be cured by retrepanation and redrainage. For the patients with repeated recurrence of CSDH removal of hematoma capsule can be considered.The causes of recurrence of CSDH are related to disease course, the thickness of hematoma capsule, the severity of encephalatraphy and whether the hematoma cavity is drained or irrigated completely, and operation methods.
