主动免疫疗法在原因不明习惯性流产患者中的应用

Objective To explore the relationship between the changes in cellular immunity and the causes of unexplained habitual abortion(UHA)as well as the mechanism of active immunotherapy on UHA patients.Methods T-lymphocyte and natural killer(NK)cell subsets(CD3+%,CD4+%,CD8+%,CD16+CD56+% and CD4+/CD8+ ratio)of peripheral blood were detected by applying flow cytometry and compared in 66 cases of UHA(UHA group,including 30 cases receiving active immunotherapy and 36 untreated UHA cases)and 30 cases of healthy fertile women(healthy control group).The re-pregnancy achievement ratio was compared between 30 treated UHA cases and 36 untreated UHA cases.Results The percentages of CD31+ and CD16+ CD56+ cells as well as CD4+/CD8+ ratio were significantly higher in UHA group than those of healthy control group(P＜0.050).As compared with those of untreated UHA subgroup,the percentages of CD3+ and CD16+ CD56+ cells as well as CD4+/CD8+ ratio were significantly lower(P＜0.050),while the re-pregnancy achievement ratio was higher(92.86% vs 05 29.03%,P＜0.001).Conclusion The changes in T-lymphocyte and NK cell subsets have something to do with occurrence of UHA.Active immunotherapy can regulate the cellular immune function and improve the re-pregnancy achievement ratio effectively.     

血浆同型半胱氨酸等水平变化与急性脑梗死的关系

目的 探讨血浆同型半胱氨酸（Hcy）、内皮素（ET）、一氧化氮（NO）、叶酸（FA）、维生素B12（VitB12）水平变化与急性脑梗死（ACl）的关系。方法测定110例ACl患者及51例健康对照者的血浆Hcy,ET、NO、FA、VitB12含量。结果ACl组血浆Hcy[（17±5）μmol／L]、ET[（33±19）μmol／L]显著高于对照组[（10±3）μmol／L、（20±13）μmoL／L]，P〈0．01；NO[（40±7）μmol/L]、FA[（8±4）ng／ml]、VitB12[（247±119）pg／ml]的水平低于对照组[（60±6）μmol／L、（10±4）ng／ml，（412±194）pg/ml]，P〈0.01,结论本研究对于患者病情观察、预后判断具有重要意义，尤其是在患者中推行加服FA和VitB12等制剂，为ACl的预防和治疗开辟了新的途径。     

实时荧光探针定量PCR在小儿沙眼衣原体肺诊断中的临床应用研究

目的 观察荧光定量PCR在小儿沙眼衣原体肺炎诊断中的应用价值及探讨不同年龄阶段小儿沙眼衣原体(CT)肺炎的临床特点.方法 将我院2004年1～12月份收治60例小儿CT肺炎做研究对象,根据年龄分组,对各组患儿均通过咽拭子或吸痰法获取标本,进行CT-DNA定量分析;回顾性总结分析60例CT肺炎.结果 60例标本中,106 拷贝数5例,105拷贝数6例,104拷贝数10例,103拷贝数39例;小婴儿CT肺炎往往无发热性肺炎,易合并细菌感染;3岁以上儿童则易出现发热、肺部体征大多阴性,而X线多表现为节段性肺炎,其临床经过类似支原体肺炎.结论 1.实时荧光定量PCR检测CT-DNA是诊断小儿沙眼衣原体肺炎最直接、最客观的指标.2.CT肺炎在不同年龄阶段的临床表现存在显著差异.     

主动免疫疗法在原因不明习惯性流产患者中的应用

目的探讨细胞免疫功能的变化与原因不明习惯性流产（UHA）的发生及主动免疫治疗机制的关系。方法用流式细胞仪测定并比较66例UHA患者和30例健康已生育妇女（NF组）及30例主动免疫治疗后的UHA患者外周血CD3^＋、CD4^＋、CD8^＋、CD16^＋CD56^＋细胞亚群百分率及CD4^＋／CD8^＋的比值;同时,比较采用主动免疫治疗30例和未采用主动免疫治疗的36例UHA患者再次妊娠成功率。结果UHA患者与NF组比较,血中CD3^＋、CD16^＋CD56^＋细胞的百分率及CD4^＋／CD8^＋比值增高,差异有统计学意义（P〈0．050）。主动免疫后CD3^＋、CD16^＋CD56^＋细胞的百分率及CD4^＋／CD8^＋比值下降（P〈0．050）。主动免疫治疗组的再次妊娠成功率为92．86％,未主动免疫治疗组29．03％,P〈0．001。结论淋巴细胞亚群比例的改变与UHA的发生有关,主动免疫治疗可调节异常的细胞免疫功能,有利于再次妊娠成功率的提高。     

荧光定量PCR在检测角膜炎泪液中单疱病毒DNA的应用价值

单纯疱疹性角膜炎主要是由单纯疱疹病毒1型引起的一种致盲率很高的传染性眼病。目前尚缺少实验室的病原学早期诊断技术。为此,作者采用荧光定量PCR技术检测45例各种类型角膜炎泪液中HSVDNA,以期达到早期快速定量检测HSVDNA来诊断HSK的目的。现报告如下。 1 临床资料 1.1 对象本组45例各型角膜炎患者,男25例,女20例,

FQ-PCR检测丙肝病毒核酸的临床价值

丙肝病毒（HCV）是单股正链RNA病毒，主要是经血液和血制品传播。丙肝易演变为慢性或发展为肝硬化或肝癌。我国发病率约为1．4％～17．2％，因此建立一种针对HCV的具有较高灵敏度、特异性和稳定性的检测方法，对HCV感染的早期诊断和治疗具有重要意义。HCV感染的标志物有HCV-RNA、抗-HCV抗体和HCV抗原。抗-HCV抗体可维持10年左右，丙氨酸氨基转移酶（ALT）由肝细胞制造，
