So overall the sequential add on strategy is a very good but rather complicated and expensive strategy that is working very well for centers and particularly in low viremic patients particularly in e antigen negative patients.

所以总的来说，序贯加用联合治疗方案是很好，但相当复杂、昂贵的方案。在各个中心对低病毒载量尤其是对HBeAg阴性的患者应用起来效果好。

结果：MPV and PDW在诊断ITP中的敏感度，特异度，阳性预测值，阴性预测值，效率以及Youden指数均为100%，而P-LCR的这些指标则低的多，其差异有统计学意义。

And the ROC was described for further analysis. Results The sensitivity, specificity, positive predictive value, negative predictive value, Youden' index and the area under the curve of ROC of IL-6 were better than those of CRP and PCT.

结果 IL-6的敏感性、特异性、阳性预测值、阴性预测值和约登指数及ROC曲线下的面积值均优于CRP和PCT。

Methods 224 patients with liver biopsy and a positive HBsAg were included in this study. The AUROC of AST、ALT、AST/ALT and APRI were identified by using receiver operating characteristic curves. Sensitivity, specificity, positive and negative predictive values, and Youden Index of APRI at optima cut-off were calculated.

调查224名乙肝表面抗原阳性的乙肝患者，利用ROC曲线分析AST、ALT、AST/ALT和APRI的面积，判断APRI的最优截断点并计算不同标准的灵敏度、特异度、阳性预测值、阴性预测值、Youden指数。

Results In 30 sera with anti-Toxoplasma IgM antibodies and 28 with IgG antibodies, the sensitivity for IgM and IgG antibody detection was 90.0%（27/30） and 85.7%（24/28） respectively, the specificity was all 100% in examining 40 healthy control sera, and the Youden index was 0.9 and 0.86 respectively.

结果 用免疫印迹试剂盒检测30份弓形虫IgM和28份IgG阳性血清，敏感性分别为90.0%（27/30）和85.7%（24/28），40份健康对照者血清的弓形虫IgM和IgG抗体均为阴性，特异性均为100%，Youden指数分别为0.9和0.86。

Results: The positive detection ratio of IHC and nested PCR were 64.2% and 81.1%, respectively. It was showed that the positive detection ratio of nested PCR was significantly higher than that of IHC (P.01). The nested PCR assay had advantages over IHC on sensitivity, specificity, Youden's index, positive predictive value and negative predictive value.

结果：免疫组化检测和巢式PCR检测的阳性检出率分别为64.2%和81.1%，巢式PCR技术检测肾癌组织支原体在灵敏度、特异度、约登指数、阳性预测值和阴性预测值方面均优于免疫组化技术。

MethodsACCP antibody and RF were detected in serum samples of 90 RA patients, 30 other diseases patients and 35 healthy blood donors.The sensitivity,specificity,positive predictive value, negative predictive value, agreement rate and Youden's index of these parsmeters for the diangnosis of RA were analyzed.

方法对90例RA患者、30例其他疾病患者和35例健康对照组血清用ELISA法检测抗CCP抗体、免疫散射比浊法检测RF，比较2种抗体单独或联合检测对诊断RA的敏感性、特异性、阳性预测值、阴性预测值、总符合率及Youden指数；探讨抗CCP抗体和RF的相关性，通过绘制ROC曲线，计算ROC曲线下面积。

EMB-resistance in 18 isolates was caused by the mutation at coden 306 in embB gene with positive rate of 62.1%. The PCR result was negative in 20 specimen from pulmonary diseases without active TB and 5 negative control strains of no MTB. The data in this study showed high specificity of 100%. Only one specimen in 7 specimen with negative result in acid-fast stain and cultivation was shown alteration in coden 306 in embB gene.

结果：130例活动性肺结核患者痰标本抗酸染色阳性38例，阳性率为29.2%(38/130)；罗氏培养阳性为79例，阳性率为60.8%(79/130)。79例培养阳性痰标本中耐乙胺丁醇29例，其中有18例在embB基因met306ATG突变，基因突变率为62.1%。20例非结核肺部疾病患者痰标本和5株非结核分枝杆菌菌株经套式PCR扩增全部为阴性，特异性为100%。7例涂阴培阴PCR扩增阳性的序列中有1例在embB基因306位密码了发生突变。

Results The incidence of VAP was 51 .5%.79 bacteria and 34 mycete were isolated.

结果VAP的发生率为51.5%，共培养出细菌79株，真菌34株；其中革兰阴性杆菌70株，革兰阳性球菌9株，VAP居首位的细菌是铜绿假单胞菌。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
