格林—巴利综合症血清唾液酸、磷脂、胆固醇的测定及其临床意义

本文应用硫代巴比妥酸(TBA)法对34例格林—巴利综合征(GBS)患者51次血清唾液酸(SA)测定。结果显示:患者血清SA含量显著高于50例对照组,血清SA阳性率亦显著高于对照组;GBS患者四肢肌力与血清SA呈负相关;以重型GBS血清SA含量显著高于轻型,病程初期高于患病后期;血清磷脂含量GBS明显高于对照组,而血清胆固醇两组变化无显著性意义。本文提示GBS血清SA含量变化能够反映周围神经损伤的程度。     

医疗纠纷的非诉讼解决方式-医疗纠纷ADR

由于在纠纷解决方面所表现出来的简便，经济，快捷，专业性及保密性强等优点，非诉讼纠纷解决方式（又可译为代替性纠纷解决方式）ADR（Alternative Dispute Resolution）逐渐成为许多国家和地区解决民事纠纷的一大趋势，我国现行医疗纠纷解决机制存在着较多的问题，有待于进一步的改善与完善，根据我国所面临的现实情况，将ADR引入医疗纠纷领域是一条快速，有效地解决医疗纠纷的途径，医疗纠纷的非诉讼纠纷解决方式主要包括仲裁，调解与和解，这3种纠纷解决方式各具特点，适用于不同情况下医疗纠纷的解决。     

眼科手术表面与球后麻醉比较的临床研究

目的：评价表面麻醉(表麻)下行内眼手术的安全性及可行性。方法：随机抽取表麻下内眼手术300眼与球后麻醉下内眼手术288眼，对两组术中、术后并发症进行对比。结果：表麻下与球后麻醉下内眼手术效果，术中、术后并发症的发生率无显著性差异，但表麻可以最大限度减少因麻醉带来的术中、术后并发症，使内眼手术更加安全快捷。结论：表麻下行内眼手术是可行的、安全的。

目的 探讨临床Ⅰ、Ⅱ期乳腺癌术前短程化疗的意义。方法 122例临床Ⅰ、Ⅱ期乳腺癌术前用CEF方案化疗1疗程，化疗后3-5d手术。结果 部分缓解21例(占17．2％)，轻度缓解76例(占62．3％)，无变化25例(占20．5％)，无临床进展病例。术前可扪及腋窝肿大淋巴结42例，化疗后30例见淋巴结明显缩小或消失。病理组织学观察75例镜下见肿瘤细胞有小点片状坏死。106例按计划手术；16例因白细胞降低等化疗反应推迟手术。全组随访1～6年，无局部复发病例；6例在随访期间1～3年内发现骨转移，经放疗和化疗控制；仅1例同时有骨转移和肺转移者于术后4年死亡；余均健在。结论 可手术乳腺癌的术前短程化疗可观察到肿瘤缩小等治疗效果，为术后化疗提供指导。并可能减少术中血行转移和提高疗效。     

A study on effects of parents age, birth order and mental retardation of unknown etiology]

On this report 461 matched cases of mental retardation of unknown aetiology were analysed on the relationship between the diseases and the parents age, birth orders with conditional Logistic regression. These cases were accurately diagnosed and selected from the Epidemiologic Survey of genetic diseases of Sichuan, China. The results found that mental retardation of unknown aetiology is related to the age of parents and birth order. The paternal age is the main factor while the maternal age in not a significant effect and birth order also in not a significant effect after readjusting the other factors. Compared to paternal age group of under 25. There are significant increase of relative risks of age group 30-34 and 45 above, about 1.8 and 2.7 fold increase in univariate analysis and 1.9 and 3.3 fold increase in controlling the maternal age and birth order, a chi-square test for trend of distribution of paternal age also indicates a significant dose response relationship between increasing risk with age. The significance of result and methods of analysis were discussed.     

Stimulation of the fastigial nucleus enhances EEG recovery and reduces tissue damage after focal cerebral ischemia.

Stimulation of the cerebellar fastigial nucleus (FN) increases CBF but not metabolism and reduces the tissue damage resulting from focal cerebral ischemia. This effect may result from enhancing CBF in the ischemic tissue without increasing local metabolic demands. To test this hypothesis, we studied whether the reduction in tissue damage is restricted to the neocortex, a region in which the CBF increase is independent of metabolism, and whether stimulation of the dorsal medullary reticular formation (DMRF), a treatment that increases both cerebral metabolism and CBF, also protects the brain from ischemia. In halothane-anesthetized Sprague-Dawley rats, the middle cerebral artery (MCA) was occluded either proximally or distally to the lenticulostriate branches. The FN or DMRF were then stimulated for 1 h (50-100 microA; 50 Hz; 1 s on/l s off). Twenty-four hours later, the infarct volume was determined. FN stimulation substantially reduced the size of the infarct, an effect that was greater with distal (-69 +/- 8%; n = 6; p < 0.001; mean +/- SD) than with proximal (-38 +/- 8%; n = 8; p < 0.001) MCA occlusion. The reduction occurred only in neocortex (-43 +/- 9%; p < 0.001) and not in striatum (-16 +/- 21%; p > 0.05). Stimulation of the FN also enhanced recovery of EEG amplitude in the ischemic cortex (+48%; p < 0.003). DMRF stimulation (n = 7) did not affect the stroke size or EEG recovery (p > 0.05). Thus, stimulation of the FN, but not the DMRF, attenuates the damage resulting from focal ischemia.(ABSTRACT TRUNCATED AT 250 WORDS)
