UF-1000i全自动尿有形成分分析仪对尿路感染的诊断价值

Objective To evaluate the application value of UF-1000i automated urine formed elements analyzer in the diagnosis of urinary tract infection. Methods 150 urine specimens were analyzed using the UF-1000i in parallel with detection of leukocyte, yeast-like fungus, and bacteria. These detection results were collected for evaluation of urinary tract infection and scatter grams were recorded. At the same time, these samples were cultured for bacterial identification, which results were compared with that of the UF-1000i. The clinical diagnose criteria of the UTI was performed as golden standard. As compare with results obtained with UF-1000i, the sensitivity and specificity of UF-1000i for diagnosis of urinary tract infection were evaluated, and the consistency were analyzed among scatter grams, bacterial culture and final diagnosis. Results The statistical results from 146 specimens showed that the positive rate of UF-1000i was 32. 9% (48/146), the positive rate of urine culture is 28. 8% (42/146). There was no significant statistical difference found (χ2 = 1.79 ,P = 0. 18 )and Kappa test showed a considerable consistency (K = 0. 775 6). The UF-1000i detection results showed the sensitivity 76. 0% ( 38/50 ), specificity 89. 6% ( 86/96 ), positive predictive value 79. 2% ( 38/48 ) and negative predictive value 87. 8% ( 86/98 ), respectively. The distribution of coccus and bacilli obtained from the UF-1000i testing was basically in accordance with the results of bacterial culture. Conclusion The "UTI-information" of UF-1000i is very important for the diagnosis of urinary tract infections.

反应性关节炎患者血清及关节液中单核因子表达及临床意义

目的 探讨单核因子在反应性关节炎(ReA)发病中的作用及其与疾病活动性的相互关系.方法 用酶联免疫测定(ELISA)方法同时测定反应性关节炎患者血液、关节液及健康志愿者血清中白细胞介素(IL-1α,IL-1β,IL-6),肿瘤坏死因子(TNF-α)等单核因子水平.结果 ReA患者血清IL-6水平明显高于健康对照组(P<0.01),而IL-1β却低于健康对照组(P>0.05);关节液中各单核因子水平(IL-1α,IL-1β,IL-6)明显高于血清水平(P<0.01),肿瘤坏死因子(TNF-α)也是如此(P<0.05).结论 在ReA的发病机制中,单核因子作为致炎因素参与了ReA的病理过程,对这些因子测定有助于临床对该疾病的诊断、治疗.     

造血干细胞移植受者免疫抑制治疗 与巨细胞病毒感染的关系

目的：探讨异基因造血干细胞移植(HSCT)术后免疫抑制治疗个体外周血中巨细胞病毒(CMV)脱氧核糖核酸( DNA)与免疫抑制剂环孢素A(CsA)血药浓度变化的关系,并评价其潜在的临床应用价值。方法：选择行异基因HSCT的32例患者进行回顾性分析。移植前采用更昔洛韦预防CMV感染。移植后应用核酸扩增(PCR)荧光检测法定期进行CMV DNA监测。根据CMV DNA检测结果将患者分为CMV DNA阴性组和CMV DNA阳性组。用酶放大免疫技术（EMIT）定期监测CsA血药浓度,分析CMV DNA与CsA血药浓度的关系。结果：异基因造血干细胞患者CMV感染率为53.13%(17/32);DNA阳性组的CsA血药浓度明显高于CMV DNA阴性组（P＜0.05）;通过ROC曲线得出异基因干细胞移植患者使用CsA药物第7,14,21天时曲线下面积与0.5比较,差异具有统计学意义（P＜0.05）,分别对应的血药浓度为203.15, 215.55和302.65 ng/mL。结论：免疫抑制药物浓度可影响CMV DNA的动态变化,CsA血药浓度偏高可能是导致造血干细胞移植受者移植后对CMV易感的原因之一,适时监测CsA血药浓度对指导临床用药有一定的辅助价值。
