利培酮治疗与细胞色素P4502D6/C188T酶基因多态性的关联分析

目的　研究利培酮临床效应的个体差异与其代谢酶细胞色素P4 5 0 2D6 (cytochromeP4 5 02D6 ,CYP2D6 )酶基因多态性的相关性。方法　对 88例符合CCMD 3精神分裂症诊断标准的患者和 96例健康对照者作病例 -对照分析。精神分裂症患者给予利培酮治疗 8周 ,用阳性和阴性症状量表 (posi tiveandnegativesymptomscale ,PANSS)评分评价利培酮疗效。采用聚合酶链反应扩增及限制性片段长度多态性 (PCR RFLP)技术对CYP2D6exonⅠ的C188T位点突变进行检测 ,分析利培酮临床效应与其主要代谢酶CYP2D6 /C188T酶基因多态性的相关性。结果　中国上海地区人群的CYP2D6 /C188T突变率(弱代谢型 )为 36 .3% ,病例组和正常对照组间基因型频率总体分布比较无显著差异 (χ2 =1.15 ,df=2 ,P >0 .0 5 ) ,两组间的等位基因频率之间比较也无显著性差异 (χ2 =0 .78,df=1,P >0 .0 5 )。进行性别及有否家族史分组后分析 ,亦无差异存在 ,且CYP2D6 /C188T突变与利培酮临床效应之间并无相关性 (χ2 =1.12 ,df=2 ;χ2 =0 .0 3,df=1,P >0 .0 5 )。结论　未发现中国人CYP2D6 /C188T多态性与利培酮临床效应的个体差异有相关性。

益母煎辅助早期妊娠药物流产50例

米非司酮配伍米索前列醇终止早孕药物流产已被广泛应用于临床，其完全流产率达90％以上，有效、安全、对身体损伤轻，许多妇女愿意选择药物流产。但药物流产存在阴道流血量多，持续时间长，易发生不全流产及致贫血、休克等弊端。笔者2003年8月～2006年10月，在口服米非司酮的第1天使用自拟中药益母煎治疗早期妊娠药物流产50例，起效快，排出孕囊完整，出血时间短，加速了流产时间，提高了疗效，现报道如下。     

Treatment of hemophilia A by living mother-to-son splenic transplantation. First case report in the world.

A case of severe hemophilia A was treated by living mother-to-son splenic transplantation. The recipient was a 9-year-old boy. After splenic transplantation, the level of blood factor VIII:C was increased, and no spontaneous hemorrhage occurred. The boy was followed up for over two years. This is a case of spleen allotransplantation with the longest function in the world.

Determination of the conjunctival goblet cell density in 43 normal subjects

The goblet cell density in the nasai inferior fornical conjunctiva was determined in 43 normal subjects (57 eyes). The mean number of goblets per 100 epithelial cells was found to be 10.17 +/- 2.81 in the young averaging 25 years and 5.25 +/- 3.38 in the aged averaging 62 years (P less than 0.01). The relation between the morphological features of the epithelial cells and the number of goblet cells was discussed.     

Protection of chickens against highly lethal H5N1 and H7N1 avian influenza viruses with a recombinant fowlpox virus co-expressing H5 haemagglutinin and N1 neuraminidase genes

Inactivated whole avian influenza virus (AIV) vaccine provides protection against homologous haemagglutinin (HA) subtype virus, but poor protection against a heterologous HA virus. Moreover, it induces chickens to produce antibodies to cross-reactive antigens, especially nucleoprotein, which is limits AIV serological surveillance. In this study, a recombinant fowlpox virus co-expressing HA (H5 subtype) and NA (N1 subtype) genes of AIV was evaluated for its ability to protect chickens against intramuscular challenge with a lethal dose of highly pathogenic (HP) AIV. Susceptible chickens were also vaccinated by wing-web puncture with the parent fowlpox vaccine virus. Following challenge 4 weeks later with HPAIV, all chickens vaccinated with recombinant virus were protected, while the chickens vaccinated with either the unaltered parent fowlpox vaccine virus or unvaccinated controls experienced 100% mortality following challenge. This protection was accompanied by the high levels of specific antibody to the respective components of the recombinant vaccine. The above results showed that rFPV-HA-NA could be a potential vaccine to replace current inactivated vaccines for preventing AI.     

益气活血汤对老年肺心病心衰患者血液流变学的影响

目的探讨益气活血汤对老年肺心病心衰患者血液流变性的影响。方法将48例肺心病心衰患者随机分为两组,均采用常规西医治疗,治疗组加用益气活血汤;观察两组治疗前后血液流变学指标变化情况。结果治疗组治疗前后比较,各项血液流变学指标改变差异有显著性,对照组治疗前后比较无统计学意义;治疗组各项指标与对照组比较差异有显著性。结论益气活血汤对肺心病心衰有改善血液流变性的作用。
