目的 系统评价心脉通治疗冠心病的临床疗效及其安全性。方法 2名研究者独立系统地检索心脉通治疗冠心病的文献,其中包括维普中文科技期刊全文数据库(VIP)、PubMed 电子期刊全文数据库、中国学术期刊全文数据库(CNKI)、The Cochrane Library 数据库、万方数据库等6个数据库。同时运用Review Manager 5.4 软件进行本研究的数据处理。结果 最终共纳入8篇文献,共计985名心脉通治疗冠心病患者。治疗前后的临床疗效、发作频率、血脂水平的Meta分析结果显示心脉通组优于常规治疗组。有3项纳入试验报告不良反应。结论 心脉通治疗冠心病的临床疗效优于常规治疗。心脉通不仅可以降低冠心病发作频率,缩短其发作持续时间,还能调节血脂水平,在治疗冠心病方面疗效确切,值得临床参考应用。

Objective To systematically evaluate the clinical efficacy and safety of Xinmaitong in the treatment of coronary heart disease (CHD). Methods Two researchers searched the literatures of Xinmaitong in the treatment of coronary heart disease independently and systematically, including VIP Chinese Sci-tech Journal full-text Database (VIP), PubMed Electronic Journal full-text Database, Chinese Academic Journal full-text Database (CNKI), The Cochrane Library Database and Wanfang Database. At the same time, Review Manager 5.4 software was used to process the data of this study. Results A total of 8 articles were included, and a total of 985 patients with coronary heart disease were treated with Xinmaitong. The results of Meta analysis of clinical efficacy, attack frequency and blood lipids level before and after treatment showed that Xinmaitong group was better than routine treatment group. Three items were included in the report of adverse reactions. Conclusions The clinical effect of Xinmaitong in the treatment of coronary heart disease was better than that of routine treatment. Xinmaitong can not only reduce the frequency and duration of coronary heart disease attack, but also regulate blood lipids level. Xinmaitong was effective in the treatment of coronary heart disease and is worthy of clinical reference.

目的 探讨河源地区机采血小板固定献血者血小板抗原系统的基因多态性特征,为建立本地区机采血小板供血者库奠定基础。方法 采用PCR-SSP方法对100例机采血小板固定献血者进行血小板抗原HPA1～17系统基因分型。结果 HPA1～17基因中成多态性分布的等位基因是HPA2a、HPA3a、HPA5a、HPA15a,其频率分别为0.96、0.49、0.99、0.515。HPA-2、HPA-3、HPA-5、HPA-15系统存在aa、ab、bb 三种表型。HPA1a、HPA4a、HPA6a-14a、HPA16a-17a基因频率为1,呈单线性分布,未发现b基因。结论 河源地区血小板HPA-3系统不配合率最高(0.420),HPA-15系统次之。建立本地区机采血小板供血者库,为患者提供HPA相合的血小板,对减少临床血小板输注无效的发生具有重要意义。

Objective To study the polymorphism of human platelet antigens in fixed apheresis platelet donors in Heyuan area and to lay a foundation for the establishment of platelets donor bank. Methods PCR-SSP method was used to analyze HPA 1～17 genotype in 100 fixed platelet donors. Results The highest numbers of heterozygotes were HPA2a,HPA3a,HPA5a and HPA15a,with frequencies of 0.96,0.49,0.99 and 0.515,respectively. The frequencies of HPA1a,HPA4a,HPA6a-14a and HPA16a-17a genes were 1,which showed a single linear distribution. Conclusion HPA-3 system were the highest mismatch rate (0.420),followed by HPA-15 system. It is great significance to establish a local platelet donor bank and provide HPA compatible platelets for patients.

目的 探讨利用微信群保留机采血小板无偿献血者的应用效果。方法 从本血站穿越安全输血标准化管理系统中调取2015年1月1日—2018年12月31日捐献机采血小板无偿献血者信息,根据初次捐献机采血小板后是否自愿加入机采微信群的机采血小板无偿献血者分为实验组和对照组,统计分析各组机采血小板无偿献血者重复献血 2～3 次和≥4 次以上机采血小板无偿献血者人数及平均献血次数。结果 2015—2018年间机采血小板采集量、献血人数及平均献血次数逐年上升;重复献血 2～3 次和≥4 次以上人数,实验组均高于对照组,机采血小板平均献血次数实验组均高于对照组,其中2016年和2018年实验组机采血小板平均献血次数高于对照组(P<0.05)。结论 通过机采微信群预约与管理机采血小板无偿献血者可提高机采血小板招募的工作效率,有效扩大和稳定机采血小板无偿献血者固定队伍。
