Results The positive rates of detecting Mycobacterium tuberculosis were13%,19%,22%,15% and 76% respectively by pathologic examination, brushing smear, sputum smear, culture after bronchoscopy and NPCR methods. Significant differences were found between NPCR and the other 4 methods (all Ps＜0.01). No positive result for Mycobacterium tuberculosis was found in 43 controls by NPCR.

结果 67例支气管内膜结核活检组织病理活动检查、刷检涂片、支气管镜检&激惹&后痰涂片、镜检术后痰培养及NPCR 检测流产阳性率分别为13%、19%、22%、15%和76%，后者与前四者相比差异有非常显著性(P均＜0.01)。43例支气管肺癌患者结核分支杆菌DNA的NPCR无一例阳性。

The motion of manganese nodules in the hoist pipe for the deep sea mining was forecasted by the model. By the simulated results, the smaller nodules, the proper hoist flow velocity and the suitable transportation concentration will ensure the safety and efficiency of the hoist system.

Ethambutol is a first-line drug used for antituberculosis therapy. It is often used in combination with isoniazid, rifampin, pyrazinamide, and streptomycin. The action of EMB in antituberculosis mechanism is the destruction of cell wall of tubercle bacilli via binding the target molecule -- arabinosyl transferases. These enzymes are involved in the polymerization of the cell wall arabinan. Inhibition of arabinan synthesis by EMB results in the accumulation of mycolic acids, leading to cell death.The EMB-resistance of MTB is involved with the mutation of emb operon or the over expression of emb operon.

乙胺丁醇是和异烟肼、利福平、链霉素、吡嗪酰胺联合治疗结核病的一线抗结核药物，EMB对结核分枝杆菌的作用机制与分枝杆菌胞壁结构破坏有关，主要作用于靶分子阿拉伯糖基转移酶，抑制了阿拉伯糖基聚合入阿拉伯半乳聚糖，从而影响细胞壁分枝菌酸-阿拉伯半乳聚糖-肽聚糖复合物的形成，导致菌细胞的死亡。

To compare the capacities of the tuberculin skin test, the interferon--based T-SPOT.TB assay, and an expert physician panel to diagnose latent tuberculosis in patients on hemodialysis.

对比结核菌素皮肤试验及基于干扰素的结核感染T细胞斑点试验以及一个内科专家小组对血透患者中潜在结核诊断的效果。

The tuberculin skin test should not be used alone to detect latent tuberculosis in hemodialysis patients; combined use of T-SPOT.TB testing and medical ealuation might offer greater accuracy.

结核菌素皮试不能单一地用于血透患者潜在结核的检测；联合应用结核感染T细胞斑点试验和医学鉴定可以提高较大的准确率。

Results Female patient, 31 years old, pregnant for 2 months after in vitro fertilization and embryo transfer, manifested with fever, shortness of breath for 1 month and the symptoms exacerbated for 1 week, was admitted to hospital with respiratory distress and severe hypoxemia. After 1 week of non-invasive ventilation, anti-bacterial and anti-virus treatments, she still had a sense of breath shortness, dry cough and was in intermittent fever, but tuberculosis-related examinations were negative. CT scan of the lungs mainly represented by ground-glass-like combined with atypical diffuse miliary change. White blood cell counts were normal. After experimental anti-tuberculosis treatments, the patient had significant improvement in symptoms, and the lesions were apparently absorpted under review of chest CT .

结果 女性患者，31岁，采取体外受精胚胎移后植妊娠2月余，发热1月加重伴气促1周入院，入院时呼吸窘迫，伴严重低氧血症，予无创通气、抗细菌和抗病毒治疗1周，仍感气促、干咳、高热，结核相关检查阴性，胸部 X 线表现以双肺毛玻璃样伴有不典型弥漫性粟粒状改变为主，白细胞计数正常，试验性抗结核治疗后，患者症状明显改善，复查胸部 CT ，病变吸收明显。
