Electro-oculogram of Retinal Vein Occlusion

Twenty five cases, including 26 eyes with retinal vein occlusion (RVO) were examined by means of the electro-oculogram. The results showed that 23 of the 26 eyes suffering from RVO exhibited abnormalities of the electro-oculogram (EOG). The potential difference and Arden ratio in the RVO eyes were lower than those in the normal eyes (P<0.01). The more the visual acuity of ill eyes was decreased, the higher the abnormal rate of EOG in ill eyes was. 14 eyes had the visual acuity less than 0.1, whose EOGs were abnortmal. Six eyes had the visual acuity from 0. 2 to 0. 4, in which the EOGs of 5 eyes were abnormal. Six eyes had the visual acuity more than 0. 5, a-mong which the EOGs of 4 eyes were abnormal. Based on the above observations, it may be considered that the circulatory disturbance resulting from RVO damages not only the internal layer but also the external layer of the retina. We suggest that EOG is a useful method for distingquishing lesions caused by RVO and may reflect the functional condition     

脐带缠绕与新生儿窒息及分娩方式

目的 探讨脐带缠绕与新生儿窒息及分娩方式的关系。方法 回顾性分析2001年5月于2002年4月脐带缠绕246例，与同期分娩的无脐带缠绕者800例进行对照性研究。结果 脐带缠绕组新生儿窒息和剖宫产率高于对照组，差异有显著性（P＜0．05，P＜0．01）；脐带越长，脐带缠绕率越高；脐带长度正常，新生儿窒息率低，脐带过长及过短，新生儿窒息率高；脐带缠绕周数越多，新生儿窒息率越高，差异有显著性（P＜0．01）。结论 脐带缠绕与脐带长度有关，脐带缠绕可导致新生儿窒息，故对脐带缠绕者应加强产前诊断及产时监护。

REGULATING FUNCTION OF COENZYMIZATION AND DECOENZYMIZATION OF THE LACTATE DEHYDROGENASE ISOZYMES IN THE MOUSE TISSUES DURING HYPOXIA

Objective. To study the characteristics of changes of LDH enzyme patterns of mice under slight hypoxia.Methods. Mice treated with artificial hypoxia, various tissues were made for the test of LDH enzymatic activity by the specific staining technique. LDH (1 -5) relative percentage enzymatic activity (RPEA) were measured with CS-910 dual-wavelength thin layer chromatography scanner.Results. The RPEA of LDH isozymes of various tissues after slight hypoxia shifted to the isozymes LDH1 and LDH2, whose principal subunits are H subunits, and the RPEA of LDH,(H4), LDH2(H3M) increased, while RPEA of LDH5(M4) in various tissues decreased prominently except the cardiac muscle, and that of LDH4(HM3) decreased as well. After polyacrylamide gel electrophoresis (PAGE) of the hypoxia treated cardiac muscle specimen was made, activity subbands originated regularly in the isozyme patterns of LDH, with the regularity of LDH1 (0 subband), LDH2 (0-1 subbands), LDH3 (0-2 subbands), LDH4 (1-3 subbands), LDH5 (2-4 subbands).     

丙型肝炎病毒感染对肾移植术后影响的临床研究

OBJECTIVE: To study the influence of hepatitis C virus (HCV) infection on the clinical outcome of kidney transplantation. METHODS: The recipient/graft survival, the incidence of acute/chronic rejection and cause of death in 86 HCV-infected recipients of renal transplantation were compared with those in another 86 recipients without HCV infection. RESULTS: HCV-infected recipients had significantly shorter 5-year survival (74.4%) than those without HCV infection (87.2%, P<0.01). The 1-year (94.2%/90.7% vs 96.8%/96.0%) and 3-year recipient/graft survival rates (88.4%/79.1% vs 90.7%/87.2%), the incidence of acute/chronic rejection (31.3% vs 21.2%, and 12.5% vs 6.5%) and the 5-year graft survival (73.3%/81.4%) were comparable between the two groups (P>0.05). Hepatic disease was identified as the primary cause of mortality. CONCLUSIONS: HCV infection may affect the long-term survival of the recipients with kidney transplantation, and therefore should be considered as a relative contraindication of kidney transplantation.

针刺对偏头痛大鼠脑内一氧化痰、5-羟色胺的影响

目的 :观察针刺对偏头痛大鼠脑内一氧化氮 (NitricOxide,NO)和 5 -羟色胺 (Sereotonin ,5 -HT)的影响 ,并探讨其防治偏头痛的作用机制。方法 :将 4 0只大鼠随机分为正常对照组、模型组、针刺预防组和针刺治疗组 ;采用硝酸还原法和反相高效液相色谱法分别测定颈静脉 (ExternalJugularVein ,EJV)中NO和 5 -HT含量。结果 :与正常对照组比较 ,模型组NO显著升高 ,5 -HT显著降低 (P <0 .0 1) ;与模型组比较 ,针刺预防组和针刺治疗组NO显著降低 (P <0 .0 1) ,5 -HT明显升高 (P <0 .0 1)。结论 :针刺不仅能治疗偏头痛 ,而且能减慢 5 -HT的降解 ,抑制NO的释放。推测针刺偏头痛可能是通过调节 5 -HT和NO的含量而实现的。     

住院产妇健康教育需求调查

目的了解住院产妇健康教育需求及希望的健康教育方式。方法采用问卷调查法,对140例住院产妇进行调查。结果产妇住院其间健康教育内容上最关心的是如何判断新生儿是否正常、出院后遇到问题时得到帮助的途径以及一些日常护理问题,最希望的健康教育方式是护士个别指导、护士集体教育。结论产科护士应根据产妇的教育需求提供有针对性的健康教育,以满足社会发展的需要。
