目的Meta分析血液灌流治疗对过敏性紫癜患儿的疗效。方法文献检索PubMed、Cochrane Library、Web of Science、中国知网、万方和CBM数据库,检索时限截至2020年2月1日。纳入行血液灌流治疗过敏性紫癜的相关原始研究。由两名研究者独立进行文献筛选、资料提取并评价纳入研究的偏倚风险后,采用RevMan5.3软件进行分析。结果13篇研究符合纳入标准,共包含803例患儿,其中试验组(血液灌流治疗组)397例,对照组406例。经分析,试验组的血尿/蛋白尿缓解时间(MD=-2.77,95%CI-3.18^-2.36,P<0.001)、腹痛缓解时间(MD=-1.70,95%CI-2.17^-1.23,P<0.001)、便血缓解时间(MD=-1.54,95%CI-1.68^-1.40,P<0.001)、住院时间(MD=-3.23,95%CI-3.60^-2.87,P<0.001)均小于对照组。结论血液灌流联合常规药物治疗可以缩短过敏性紫癜患儿的血尿/蛋白尿缓解时间、腹痛缓解时间、便血缓解时间和住院时间。
Group A rotavirus are the most frequently detected viral agent associated with the acute diarrhea in calves.In order to investigate the situation of rotavirus strains circulating in diary farms,a total of 117 fecal specimens were collected from diarrhea calves under 4 weeks-age on Yinluo diary farm in Daqing region in China from 2008 to 2009.Ten specimens were detected to be positive by a Rotavirus Group A Diagnostic Kit,which confirmed that the rotavirus was important viral agent associated with diarrhea in this diary farm.Based on the new classification system,G10P[11] genotype was determined in rotavirus positive samples.Sequence and Phylogenetic analysis indicated DQ-75 strain was introduced into our country with imported bovine.
