血糖波动幅度与自主神经功能损害的关系

植物神经病变是糖尿病常见的并发症之一。心率变异(HRV)是判定糖尿病是否伴有自主神经病变损害的准确的敏感性指标,也是预测其高危患者预后的一项无创性独立指标。血糖波动对糖尿病慢性并发症的危险性可能超过血糖绝对水平[1]。近年来的研究表明,糖尿病慢性并发症的发生、发展不仅与整体血糖水平密切相关,而且与血糖变异有密切关     

严重眼外伤的治疗

目的观察一期清创缝合术后联合玻璃体切除治疗严重眼外伤的效果。方法20例（20只眼）严重眼外伤眼球一期缝合后采用玻璃体切除联合手术：去除浑浊的屈光间质、直视下摘出异物,处理脱离的视网膜、脉络膜使其复位。眼内炎者玻璃体切除同时行气液交换、眼内注药。结果手术后有一定视力改善者19例（95．0％）,仅1例无光感。有效率95．0％。结论严重眼外伤一期正确、适当的清创缝合,适时行玻璃体切除联合视网膜复位术,将更有效的挽救眼球和视功能,是行之有效的手术方法。     

醒脑静注射液对正常人脑电图的影响

醒脑静注射液已广泛应用于临床,可治疗多种疾病.对其作用机制的研究已有很多.为了进一步了解醒脑静注射液对人脑电生理的影响,了解醒脑静注射液的醒神作用与人体脑电信号变化的关系,我们对30例正常人静脉注射醒脑静注射液前后脑电图变化及有无不良反应等进行了观察.     

晶状体过敏性眼内炎的氧自由基机制

目的 探讨晶状体过敏性眼内炎（ＰｈＥ）的发病机制。方法 采用顺磁共振技术，检测实验性ＰｈＥ大鼠眼局部组织氧自由基与超氧化物歧化酶（Ｃｕ．Ｚｎ－ＳＯＤ）水平。结果 ＰｈＥ发病时氧自由基显著自升高，此后逐渐降低；而Ｃｕ．Ｚｎ－ＳＯＤ的变化与之相反。这些变化与眼组织炎症反应及病理变化基本一致。结论氧基可能是导致ＰｈＥ早期炎症和病理损害的重要介质。     

RELATIONSHIP BETWEEN HUMAN PAPILLOMAVIRUS INFECTION AND UTERINE CERVICAL CARCINOMA DEVELOPMENT A PATHOMORPHOLOGICAL OBSERVATION OF 357 CASES

357 cervical tissue sections with different diagnoses were reviewed with Meisels' criteria. The results showed that 257 0f 357 (71.99%) presented uterine cervical condyloma, in which 141 were simple condyloma, 50 dysplasia with condyloma and 66 car cinoma with condyloma. Most of the cervical con dylomas occurred in native squamous epithelia and were flat type (92.22%). Endophytic type was only in 7.78%, and no exophytic type was found. In the same section, cervical condyloma lesions were closely adjacent to dysplasia or carcinoma foci. In the pro- cess of the development of cervical carcinoma, the extent of the associated condyloma became severer as its proportion decreased gradually; quite seeming- ly, there is a spectrum of continuous pathomor. phologic changes from cewical condyloma to carcinoma.
