山东省基本消灭丝虫病后10年纵向监测结果分析

山东省于１９８３年基本消灭丝虫病后，１９８４～１９９３年连续１０年对原高，中度流行区的１８个村进行纵向监测，人群微丝蚴主经和密度逐年下降，分别由１９８４年的０．１７％的１４．２ｍｆ／１２０μｌ，下降至１９９１年的０．０３４％和１．２ｍｆ／１２０μｌ，１９９２～１９９３连续２年未发现微丝蚴血症者，观察３２例微丝蚴阳性者均于３～６年内全部自然转阴，１０年中蚊虫平均自然感染率０．０４％（１５７／３８２５     

一起由高原鼠兔引起的人间腺鼠疫

青海省玉树县下拉秀乡曾先后多次发生过人间鼠疫,但该乡的钻多村地区从未发生过人间鼠疫。该村在喜马拉雅旱獭(简称旱獭)分布区内同时栖息着大量的高原鼠兔,旱獭体表的媒介动物在高原鼠兔体上也可以检到,该村牧民尤其是青少年及儿童经常捕捉活的高原鼠兔玩耍。1996年8月26日该村1名少年及1名儿童因此感染腺鼠疫。

蛛网膜下腔出血并发脑血管痉挛的研究进展

蛛网膜下腔出血(subarachnoid hemorrhage简写SAH)后可出现两个时相的脑血管痉挛(cerebral vascular spasm简写CVS),即急性CVS和迟发性CVS,一般认为急性CVS是血管的功能性变化,而迟发性CVS则是血管发生结构性病理改变,致血管内腔狭窄,产生脑缺血性神经症状,甚至发展为脑梗塞或死亡,并发率为20～36％。 1 发病机制 对严重CVS病理检查发现受累血管的中层增生和内膜坏死,脑血管动物模型也证实受累血管病变与此相同。所以CVS实质上是脑血管发生了结构性病理改变而不仅是痉挛,早期持续性平滑肌痉挛对血管壁病变起到促进     

The Experimental Study on Treatment of Glucocorticoid-Induced Ischemic Necrosis of Femoral Head by Gu Fu Sheng Capsule

Objective: To observe the effects of Gu Fu Sheng Capsule (骨复生胶囊 GFSC) on nitric oxide (NO) level and fibrinolytic activity in rabbits with glucocorticoid-induced ischemic necrosis of femoral head (GINFH)so as to explain the therapeutic mechanism of GFSC Methods: 48 rabbits were randomly divided into 4 The models of GINFH were produced by injection of glucocorticoid hormone for 8 weeks. From the 9th week, GFSC decoction was given to the rabbits of the group A (45g. kg-1 d-1) and MSGP extract was given to the group B (0.17 g kg-1 d-1) and the same volume of normal saline to group C and D by intragastric infusion. The content of plasma nitric oxide (NO), and activities of tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor (PAI) were detected after the hormone was injected for 4 and 8 weeks and after the drugs were given for 4 weeks. Results: Compared with the group D, the contents of NO and t-PA activity in the group C decreased significantly (P＜0.01), but the activity of PAI increased significantly (P＜0.01). Compared with the group C, the contents of NO and t-PA activity in the group A and B increased significantly (P＜0.05), but the activity of PAI decreased significantly (P＜0.05), with no significant difference between the two treatment groups (P＞0.05). Conclusion: GFSC could increase the level of NO, protect endotheolial cells and improve fibrinolytic activity, which might be the mechanism of GFSC in curing GINFH.
