目的探讨脑创伤后迟发脑梗死的发生机制,临床诊断及救治措施。方法对32例经影像学证实为颅脑创伤后迟发脑梗死患者的临床资料进行回顾分析。结果出院时按GOS标准评价:恢复良好12例、中残5例、重残4例、植物生存3例,死亡8例,其中非手术治疗20例,存活14例,死亡6例,死亡率30%;手术治疗12例,存活10例,死亡2例,死亡率17%。结论及时诊断与合理有效的治疗是提高脑创伤后迟发性脑梗死的治愈率及提高患者生存质量的关键。     

重睑术后继发上睑下垂的成因及防治

重睑术为最常见的、操作简单的门诊手术,但若想术后取得满意的效果却并非易事[1],术后并发症相对较多,其中继发上睑下垂是较严重的并发症之一,我们复习相关文献发现,关于如何在重睑术中、术后早期发现、早治疗,避免医疗纠纷及并发症发生的报道不多见。本文就重睑术后继发上睑下     

兔局灶脑缺血后脑片[Ca~(2 )]i的变化

目的：研究脑缺血后脑片[Ca2＋]i变化。方法：采用新型Ca2＋荧光指示剂Fura－2双波长法测定兔大脑中动脉阻塞（MCAo）局灶脑缺血后脑片细胞内游离钙（[Ca2＋]i）。结果：脑缺血后脑组织[Ca2＋]i显著升高。结论：[Ca2＋]i在脑缺血损害中起重要作用。

用同位32~P标记乳酸脱氢酶-C(LDH-C)cDNA作为探针,与小鼠胸腺、脑、胰、心肌、骨骼肌、睾丸、肾、肺、肝的RNA以及人胰、皋丸、肝、骨骼肌、心肌及脑的RNA分别作点溃杂交(dot blot hybridization)及Northern印迹杂交,证实LDH-C基因只在睾丸中特异性表达。     

合理使用高张葡萄糖

临床护理工作中发现，高张葡萄糖的使用，在某些情况下存在一定的危险性，使用不当则加重病情的发展，甚至危及病人的生命。因此要掌握好高张葡萄糖对某些疾病所产生的不良影响，做到预防在先，合理使用。     

胎儿主要肢骨发育时间表──超声骨龄

用Ｂ超检测正常妊娠中的胎儿。选择受精龄为１２至３８整周（ｃｏｍｐｌｅｔｅｄｗｅｅｋ）的胎儿２９７例。测量其主要肢骨（干）长度。并将所测数据进行统计学处理。结果表明胎儿肢骨的生长发育与胎龄有显著的正相关关系。

Polymorphism in the promoter region of the apolipoprotein AI gene associated with differences in apolipoprotein AI levels: The European Atherosclerosis Research Study

The effect associated with the substitution of adenine (A) for guanidine (G) in the promoter region of the apolipoprotein AI gene (?75 bp) with plasma apo AI and high-density lipoprotein (HDL) levels was investigated in the European Atherosclerosis Research Study (EARS). This is a study of healthy offspring (cases) of fathers who had suffered premature myocardial infarction (MI) before age 55 years (n = 565) and age- and sex-matched controls (n = 1,078) from 12 European countries, divided into 5 regions based on geography and language. The frequency of the polymorphism was not significantly different among the regions and the relative frequency of the rare A allele was similar in cases and controls (0.159 vs. 0.142) combining data from all regions. Individuals with one or more A allele had significantly higher plasma apo AI levels (P < 0.05) than individuals homozygous for the G allele. This effect was consistent in all regions. The data were analyzed separately in males and females. In females, those with one or more A allele had significantly higher apo AI levels (P = 0.05) than individuals homozygous for the G allele, and this raising effect of the A allele was greater in cases than controls for both apo AI (5.23% vs. 1.56%) and HDL (4.48% vs. 1.89%). In males, the A allele was associated with higher levels of apo AI and HDL, but the effect was much smaller and the differences did not reach statistical significance. In the females, where the effect of the A allele was strongest, the effect on apo AI associated with genotype was evident in non-smokers, and individuals with one or two A alleles had 3.6% higher apo AI and 3.14% higher HDL levels than individuals homozygous for the G allele. However, in the female smokers the raising effect of the A allele was greatly reduced (0.56%). Thus genetic variation in the promoter region of the apo AI gene is associated with differences in apo AI and HDL levels in healthy individuals throughout Europe, but the effect is modulated by gender, environmental factors such as smoking, and a family history of MI.
