目的 了解惠州地区无偿献血者中抗-Mur及Mur抗原的频率,为指导临床输血及建立稀有血型红细胞库提供依据。方法 用微板盐水法和凝聚胺法筛查8686名自愿无偿献血者血浆中的抗-Mur,再用微柱凝胶卡方法进一步确认;采用人源抗-Mur血清检测1119名献血者Mur抗原的红细胞表型。结果 无偿献血者血清中抗-Mur频率为0.35%(31/8686),男女间的差异有统计意义(P<0.05),女性高于男性;Mur抗原阳性频率为5.61%(63/1119)。结论 惠州地区无偿献血者中抗-Mur频率较高,而Mur抗原阳性则相对较常见,在输血前检查项目中增加Mur血型抗原抗体检测是非常必要的。
Objective To investigate the frequency of anti-Mur and Mur antigen among blood donors in Huizhou city and provide data for guiding clinical transfusion and establishing red blood cells library of rare blood type. Method Micro-plate brine method and polybrene method are used to screen anti-Mur from 8686 blood donors. DG Gel Coombs cards are used to confirm the result. Human anti-Mur serum is used to screen the phenotypes from other 1119 blood donors. Results The frequency of anti-Mur was 0.35%(31/8686). The differences between men and women had statistical significance (P<0.05), of which women were higher than men. The frequency of Mur antigen positive was 5.61%(63/1119). Conclusion The blood donors in Huizhou showed a high frequency of anti-Mur and a relatively high frequency of Mur antigen, so it is very necessary to add test method of Mur blood group antigen and antibody before the donors carry out the blood transfusion process.

目的 了解佛山市南海区性传播疾病(STD)门诊病人单纯疱疹病毒感染的流行情况。方法 对2013年1月—2014年6月间前往佛山市南海区3个规范化性病门诊就诊的患者进行问卷调查、生殖器疱疹临床诊断和单纯疱疹病毒分类抗体检测、分泌物实时荧光定量聚合酶链反应(FQ-PCR)检测。结果 350例疑似生殖器疱疹患者中,HSV-I的IgM 和IgG的检出率分别是5.4%(19/350)和87.7% (307/350),HSV-II的IgM 和IgG检出率分别是2.9%(10/350)和42%(147/350),两种血清型中以HSV-I感染为主,且IgG 阳性率高于IgM(HSV-I的χ2=238.1,P<0.005;HSV-II的χ2=259.08,P<0.005);HSV-ⅡIgG感染者147例(男115例,女32例),感染率分别为41.2% 和42.7%。男性HSV-ⅡDNA感染率高于女性,二者差异有统计学意义(χ2=3.94,P<0.05)。结论 本地区性病门诊中HSV抗体检出率高,以HSV-I感染为主;对于疑似生殖器疱疹患者,同时进行HSV抗原及血清HSV-I、HSV-II的 IgM和 IgG抗体联合检测更有助于临床GH诊断;男性患者易于临床诊断。
Objective To investigate the epidemiological characteristics of herpes simplex virus infection in patients attending a sexually transmitted diseases(STD)clinic in Nanhai District of Foshan. Methods The 350 patients attending the three standardized STD clinic in Nanhai District of Foshan from January,2013 to June,2014 were interviewed with an anonymous questionnaire,blood-tested for HSV(IgM、IgG) antibody.And secretion was detected by FQ-PCR for HSV antigen. Results In 350 patients with suspected GH,the positive rate of HSV-I IgM and IgG were 5.4%(19/350)and 87.7%(307/350).The positive rate of HSV-II IgM and IgG were 2.9%(10/350)and 42%(147/350),respectively.HSV-I infection was principal in two serologic types,and the positive rate of IgG was higher than that of IgM (P<0.05).There were 147 patients infected HSV-II IgG(male 115,female 32).The infection rate is 41.2% and 42.7%.The infection rate of HSV-ⅡDNA in men was higher than that in women.There was a significant difference between them(P<0.05). Conclusion There was a high positive detection rate of HSV from sexually transmitted disease clinic in this region.And HSV-1 was principal.For patients with suspected genital herpes,detection of HSV antigen tests combined with HSV-I、HSV-II IgM and IgG serum antibody tests is more helpful in the clinical diagnosis of genital herpe.HSV infected men patients were likely to clinically diagnose.
