目的 通过研究统计痰TB-DNA、痰分枝杆菌核酸、痰涂片找抗酸杆菌、血清T-SPOT.TB试验对肺结核的诊断敏感度、特异度、诊断预测值、诊断准确率,进一步探讨不同临床检测方法对肺结核的诊断价值,指导肺结核患者的临床诊治。方法 通过回顾性分析我院2017年1月—2019年12月呼吸内科、感染性疾病科诊断为活动性肺结核的患者,以痰结核菌培养结果为对照标准,分别统计出痰TB-DNA、痰分枝杆菌核酸、痰涂片找抗酸杆菌、血T-SPOT.TB试验对肺结核的诊断敏感度、特异度、阳性预测值、阴性预测值、诊断准确率,探讨我院临床上四种实验室方法对诊断肺结核的临床价值。结果 通过上述方法统计出痰TB-DNA、痰分枝杆菌核酸、痰涂片找抗酸杆菌、血T-SPOT.TB试验对肺结核的诊断敏感度分别是84.7%、88.1%、74.7%、96.0%,特异度分别是65.3%、69.2%、86.5%、17.8%,阳性预测值分别是83.0%、85.%、92.0%、70.7%,阴性预测值分别是68.1%、73.5%、62.1%、68.4%,诊断准确率分别是78.2%、82.0%、78.5%、70.5%。结论 跟传统方法痰结核菌培养、痰涂片找抗酸杆菌比较,TB-DNA、分枝杆菌核酸、TB-SPOT.TB试验在时效、灵敏度方面更具优势,能敏感检测出人体是否感染肺结核,对患者的早期诊断及指导治疗具有重要意义。

Objective To investigate the diagnostic sensitivity, specificity, predictive value and diagnostic accuracy of TB-DNA, mycobacterium sputum nucleic acid, acid-fast bacilli on sputum smear and serum T-SPOT.TB test for tuberculosis, so as to further explore the significance of different clinical detection methods for tuberculosis and guide the clinical diagnosis and treatment of tuberculosis patients. Methods By retrospective analysis of January 2017-December 2019, patients from respiratory medicine, infectious diseases departments diagnosed with active tuberculosis, sputum culture results of tuberculosis bacterium as control standard, we figured out sputum TB-DNA, sputum mycobacterium nucleic acid blood, sputum smear for acid fast bacilli, T-SPOT. TB test to the diagnosis sensitivity, specific degree, positive predictive value, negative predictive value, diagnostic accuracy, to explore the clinical value of four clinical laboratory methods in our hospital. Results According to the above methods, the diagnostic sensitivity of sputum TB-DNA, sputum mycobacterial nucleic acid, sputum acid-fast bacilli on smear and blood T-SPOT.TB test for tuberculosis was 84.7%、88.1%、74.7%、96.0%, and the specificity was 65.3%、69.2%、86.5%、17.8%, respectively. The positive predictive value was 83.0%、86.6%、92.0%、70.7%, and the negative predictive value was 68.1%、73.5%、62.1%、68.4%, respectively. The diagnostic accuracy was 78.2%、82.0%、78.5%、70.5%, respectively. Conclusion Compared with the traditional methods of culture and sputum smear for acid-fast bacilli, TB-DNA, mycobacterial nucleic acid and T-SPOT.TB test had more advantages in terms of timeliness and sensitivity. It is great significance for the early diagnosis and treatment of patients to detect whether they are infected with tuberculosis sensitively.

目的 研究限制会阴切开及会阴不同切口对产妇产后出血、疼痛及性功能的影响。方法 选取我院2012年4月—2013年4月头位自然分娩产妇480例,抽签随机分为三组,每组160例,实施限制会阴切开的为限制组,实施会阴侧切的为侧切组,实施会阴正中切开的为正切组,比较三组产妇产后2 h出血量、产后住院时间、产妇会阴阴道裂伤率、产后疼痛程度和性功能满意程度。结果 产后2 h产妇出血量限制组(203.65±76.68)mL较侧切组(241.41±80.63)mL和正切组(239.15±85.19)mL少(P＜0.05);侧切组(1.64±0.87)d产后住院时间较限制组(1.37±0.64)d较长(P＜0.05);限制组会阴Ⅰ/Ⅱ°裂伤率为86.25%较侧切组1.25%和正切组6.88%较高(P＜0.05);侧切组2.50%和正切组3.13%会阴Ⅲ/Ⅳ°裂伤较限制组0%较高(P＜0.05);女性性功能指数限制组(22.69±2.65)分较侧切组(19.12±2.05)分与正切组(18.96±2.16)分较高(P＜0.05)。结论 实施限制会阴切开的产妇术后出血量少,会阴重度裂伤率低,保证了会阴完整性,产后性功能满意度高,值得临床上应用推广。
