前臂逆行骨间背侧皮瓣的临床应用

目的总结前臂逆行骨间背侧皮瓣的临床疗效。方法回顾性分析42例前臂逆行骨间背侧皮瓣，并结合文献阐明其变异程度及变异的处理。结果骨间背侧血管在前臂中1／3缺如1例．皮瓣边缘坏死；皮瓣向近端延伸超过4cm者4例，远端坏死，延迟愈合；其余均一期愈合：结论虽然前臂骨间背侧血管有变异，但前臂逆行骨间背侧皮瓣仍是修复手背中等大小创面较为理想的方法，以近点皮肤穿支向近端延伸皮瓣不要超过4cm。     

Comparison of fMRI statistical software packages and strategies for analysis of images containing random and stimulus-correlated motion.

The objectives of this study were to use computer-generated phantoms containing real subject motion to: (1) compare the sensitivity of four commonly used fMRI software packages and (2) compare the sensitivity of three statistical analysis strategies with respect to motion correction. The results suggest that all four packages perform similarly in fMRI statistical analysis with SPM2 having slightly higher sensitivity. The most sensitive analysis technique was to perform motion correction and include the realignment parameters as regressors in the general linear model. This approach applies to all four packages examined and can be most beneficial when stimulus-correlated motion is present.     

Alpha-tocopherol and beta-carotene do not protect marmosets against the dopaminergic neurotoxicity of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine

Idiopathic Parkinson's disease (PD) may possibly be caused by one or more unidentified neurotoxins present in the environment, or formed endogenously, which progressively damage dopaminergic nigrostriatal neurons. N-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is an experimental neurotoxin which produces biochemical and neuropathological changes in humans, lower primates and mice that closely resemble those found in PD. Because the mechanisms of neuronal damage in both idiopathic PD and in the MPTP model of PD may involve free radical formation in the substantia nigra, antioxidants might protect dopaminergic neurons. Previously, we found that both alpha-tocopherol and beta-carotene partially protected mice against MPTP. However, in the experiments described in this paper, neither alpha-tocopherol nor beta-carotene, each administered in massive doses, had any demonstrable protective effect for dopaminergic nigrostriatal neurons in marmosets injected with low doses of MPTP. Without more knowledge about the identity of the neurotoxin(s) causing idiopathic PD, and their mechanism of action, it is not possible at this time to predict whether these 2 antioxidants might be clinically useful in preventing or ameliorating PD.

益肾化浊注射液对慢性肾功能衰竭大鼠残余肾中细胞因子含量的影响

通过观察益肾化浊注射液对5／6肾切除大鼠残余肾中细胞因子含量的影响，益肾化浊注射液延缓慢性肾功能衰竭（CRF）模型大鼠肾功能减退的作用机理。结果显示：益肾化浊注射液可以降低5／6肾切在鼠血清肌,尿素氮（P＜0．01），下调肾组织中白细胞介素－1（IL－1）（P＜0．05），白细胞介素－8（IL－8）（P＜0．05）及肿瘤坏死因子（TNF）（P＜0．05）的总体水平，说明益肾化浊注射液可以通过下调5／6肾切除大鼠残余肾中相关细胞因子含量，抑制促炎细胞因子对肾脏的损害，从而延缓CRF的进展。
