埃塞俄比亚德布拉巴汗市医院眼科门诊病人１４３６人中查出盲目患者１６８人，占门诊病人的１１．７％。其中双眼盲６７人，占门诊病人的４．６７％，占盲人的３９．８８％；单眼盲１０１人，占门诊病人的７．０３％，占盲人的６０．１２％。通过分析，初步找出了在埃塞的三大致盲病因，即白内障、青光眼和眼外伤。其中白内障具有重要的开盲意义。     

5km重复低压缺氧对小鼠肝脏及脾脏中微量元素的影响

目的 探讨5km重复低压缺氧对小鼠肝脏及脾脏中微量元素的影响。方法 将小白鼠分为5km重复低压缺氧实验组及地面对照组。实验组每天进行5km重复低压缺氧30min,连续7d后，处死小鼠，取肝脏、脾脏烘干至恒重，采用火焰原子吸收法测定锌、铜、铁。结果 5km重复低压缺氧小鼠肝脏中Cu、Fe含量与对照组比较有显差异(P＜0．05)；脾脏中微量元素Fe的含量与对照组比较有显性差异(P＜0．05)。结论 5km重复低压缺氧，使肝脏中Fe、Cu含量降低，脾脏中Fe含量升高。     

对500名广州妇女关于激素替代疗法态度的调查

【目的】了解广州妇女对激素替代疗法 (HRT)的态度。【方法】对 5 0 0名妇女进行面对面的问卷调查 ,记录她们对绝经症状以及激素替代疗法的认识和态度。【结果】 5 9%的妇女认为对绝经症状应该求医 ,41%妇女采取消极忍耐的态度 ,76 2 %的人选择妇科就诊 ,19 8%的妇女选择内外科或精神科 ;仅有 2 2 1%的妇女听说过HRT。绝经后妇女应用HRT的有5 9% ,2 4 4%的人不知道HRT的益处 ,知道可以预防骨质疏松和心血管疾病的分别有 17 8%和 10 8% ,5 9 8%的人不知道HRT的副作用 ,13 6 %的人不知道在哪科医生的指导下应用HRT ,40 4%的人不知道何时开始应用HRT。【结论】我们认为广州妇女的围绝经期保健意识不强 ,对HRT的了解很少 ,对HRT的利弊认识不足 ,有必要开展这方面的科普教育工作。     

Analysis thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis in the lower extremities

Objective:To explore the effect of thrombolysis with anticoagulation treatment forearly stage of deep vein thrombosis of lower extremity.Methods:The clinical data of 10 patients at the early stage of deep vein thrombosis(DVT)in the lower extremuites treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively.Results:The thrombolytic effect was significant.After treatment,the deep veins were recanalized without regurgitation in 75.3% of the patients.The total effective rate was 100%.Only three patients had hemorrhagic complication,but none of the patients died.Conclusion:Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.     

流感相关性脑病

流感相关性脑病（influenza—associated encephalopathy，IAE）是指在急性流感过程中伴随中枢神经系统功能障碍的一种临床综合征，不包括脑膜炎、脊髓炎和高热惊厥。典型的IAE临床表现为急性高热后突然惊厥发作，起病1～2d内快速进展至昏迷状态或死亡，病情凶险，病死率约30％。早在1918年西班牙流感时期就发现一些嗜睡性脑炎与流感有关，当时还不能分离流感病毒故无法证实病原。     

血小板活化状态在先天性心脏病中的作用

目的：研究血小板的活化状态在先天性心脏病中的作用。方法：采用流式细胞术测定P选择素的表达作为血小板活化的特异性指标，患者分为非紫绀组32例、紫绀组9例、健康对照组12例．研究先天性心脏病患者血小板活化功能的变化。结果：与健康对照组相比，非紫绀组和紫绀组先天性心脏病患者P选择素的表达均明显升高，紫绀组尤为显著。结论：先天性心脏病患者存在血小板的活化状态，紫绀型先天性心脏病更明显，这可能是引起这些患者止血功能异常的原因之一。     

Rosiglitazone down-regulates lipopolysaccharide-induced expression of CD40 and intercellular adhesion molecule 1 in rat peritoneal mesothelial cells through a NF-κB dependent mechanism

Objective To investigate the effect and mechanism by which PPARγ ligand, rosiglitasone, regulates the expression of CD40 and intercellular adhesion molecule 1 (ICAM-1) in the rat peritoneal mesothelial cells (RPMCs) induced by lipopolysaccharide (LPS). Methods RPMCs were harvested from Sprague-Dawley rat peritoneal cavity and maintained under defined in vitro conditions. The cells were randomly divided into groups as follows: medium, LPS (5 mg/L), LPS (5 mg/L)+BAY11-7085(5 μmol/L, NF-κB inhibitor), rosiglitazone (10 μmol/L or 20 μmol/L, peroxisome proliferator-activated receptor γ activator), LPS (5 mg/L)+rosiglitazone (10 μmol/L)+GW9662 (3 μmol/L, peroxisome proliferator-aetivatcd receptor γ antagonist), and LPS (5 mg/L)+vehicle (DMSO 0.2 ml/L). The expressions of CD40 and ICAM-1 RNA in RPMCs were examined by RT-PCR after 3 hour treatment, and the protein expressions of CD40, ICAM-1, p-NF-κB p65 and p-IκBα were examined by Western blot or immunofluorescence after 24 hour treatment. Results Following treatment with LPS, both the expressions of CD40 and ICAM-1 protein in RPMCs were up-regulated significantly (P<0.05), and the phosphoralation of p65 was increased greatly (1.10±0.17 vs 0.55±0.06, P<0.05). BAY11-7085 (5 μmol/L) significantly decreased the protein expression of p-p65 (0.22±0.11 vs 1.10±0.17, P<0.01), CD40 (0.34±0.02 vs 0.50±0.06, P<0.05) and ICAM-1 (0.35±0.16 vs 0.74±0.03, P<0.05). Pretreated with rosiglitazone for 3 h then added with LPS for 1 h, the levels of p-p65, CD40 and ICAM-1 in RPMCs were significantly decreased compared with those of LPS group (0.77±0.08 vs 0.90±0.10, P相似文献
