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.     

老年性腰椎间盘突出症的手术治疗

老年性腰椎间盘突出症是指60岁以上发病者．其发病率相对较低，在病理、临床表现、手术方式、围手术期处理等方面都有别于中、青年患者。我院1995年1月～2000年8月共手术治疗腰椎间盘突出症417例．其中老年性腰椎间盘突出症46例，占11．03％。现将资料完整并获得随访的41例报告如下。     

经氯硝柳胺浸泡后湖北钉螺脑神经节的超微结构变化

用透射电镜进一步观察了湖北钉离神经节的纤维鞘，神经节胞体区和神经纤维网的超微结构，并且在神经纤维网部位首先发现了两个典型突触，经氯硝柳胺浸泡后，钉螺脑神经节的超微结构发生改变，神经纤维，神经胶质细胞和神经细胞内的线粒体由变性至坏死，神经细胞内的的糖原有含量显著减少，神经纤维网也发生变化坏死，这为阐明氯硝柳胺的灭螺机制提供了有用的资料。     

Kartagener综合征

Kartagener综合征是因粘液纤毛先天性缺陷所引起的一种较少见疾病,它由内脏反位、支气管扩张、副鼻窦炎三联征组成.1904年Siewert最早报告1例,但未解释此三联征之间的任何关系,1933年Kartagener报告4例,并指出此三联征不是偶然的巧合,而是一个综合征.此后屡见此等病例报告,1956年Kartagener查阅世界文献共计216例,国内孟宪慎于1959年首报1例后,至今仅见10     

氢呼吸试验与钡餐透视测定胃小肠传递时间的比较

以乳果糖为试验用糖进行氢呼吸试验(BHT)对23例受试者的胃小肠传递时间(SSITT)进行了测定,并与钡餐透视所测结果进行了对比研究。 1.材料与方法 经内镜检查明确诊断的受试者23例,其中消化性溃疡8例,非溃疡性消化不良9例,正常健康者6名。23例中男16例,女7例,年龄18     

老年全身麻醉患者血清ADP、S-100β蛋白及HIF-1α水平与术后认知功能障碍的相关性分析

目的探讨老年全身麻醉患者血清脂联素(ADP)、S-100β蛋白及缺氧诱导因子-1α(HIF-1α)水平与术后认知功能障碍(POCD)的相关性。方法选取南阳市中心医院2017年1月至2019年1月收治的159例接受手术治疗的老年患者,根据术后简易精神状态检查表(MMSE)评分分为POCD组(MMSE<27分,n=53)和非POCD组(MMSE≥27分,n=106),比较两组患者手术前后ADP、S-100β蛋白、HIF-1α水平变化,Pearson相关性分析MMSE评分与血清ADP、S-100β蛋白、HIF-1α水平的相关性,受试者操作特征(ROC)曲线分析血清ADP、S-100β蛋白、HIF-1α水平对老年全身麻醉POCD的预测价值。结果术后两组血清ADP水平和MMSE评分均明显降低,S-100β蛋白、HIF-1α水平明显提升,POCD组较非POCD组改变更明显(P<0.05);Pearson相关性分析显示,POCD组术后MMSE评分与血清ADP水平呈正相关,与S-100β蛋白、HIF-1α水平呈负相关(P<0.05);ROC曲线显示,ADP+S-100β蛋白+HIF-1α预测老年全身麻醉患者POCD的曲线下面积(AUC)、敏感度、特异度高于各指标单独预测。结论老年全身麻醉POCD患者血清ADP水平明显降低,S-100β蛋白和HIF-1α水平明显提升,与POCD发生密切相关,联合检测能提升POCD预测价值。     

IMMUNOLOGICAL STUDIES ON THROMBOANGIITIS OBLITERANS

Using humoral immunity (gamma-globulin 18 cases, IgG, IgA, IgM each 30 cases, CH50, C3, C4 each 29 cases and CIC 31 cases), cellular immunity (E-RFC 68 cases, As 30 cases, SmIg, SmIgG each 18 cases, IMIT 30 cases) and immunopathological manifestations (light microscope, fluorescence microscope, transmitted electron microscope each 7 cases) as indices, we studied the immunological changes of "progressing", "remittent" and "stabilized" groups of patients with thromboangiitis obliterans (TAO) in different stages. Humoral immunity indicated that gamma-globulin, immune complex and IgG were all increased; cellular immunity indicated that the rate of T cells and suppressor cells was declined, while that of B cells was elevated. Immunopathologically, under light microscope all the layers of involved vessels were infiltrated with neutrophils, lymphocytes and monocytes; under fluorescence and electron microscope, immune complexes were found in the involved vessel walls. Our preliminary results suggest that TAO is an autoimmune disease relevant to antigen-antibody complex.     

TREATMENT OF HYALINEMEMBRANE DISEASE BYHUMAN AMNIOTIC FLUIDSURFACTANT

A case of hyaline membrane disease was treated successfully with pulmonary surfactant (PS) isolated from human amniotic fluid. Dosage was 150 mg phospholipid/kg. The exogenous surfactant was instilled into the airway via a tracheal cannula. Clinical symptoms, PO2 and FiO2 improved evidently 24 hours after administration. L/S ratio and phosphatidylglycerol recovered gradually in aspirates. Lung X-ray film manifested "white lung" before instillation of surfactant and showed a striking improvement 3 days after treatment. The duration of mechanical ventilation was 6 days. During the period of recovery complications of patent ductus arteriosus and bacterial pneumonia developed. However, the patient recovered completely and was discharged 32 days after admission.
