目的 探讨肠道菌群多样性及丰度在抗结核治疗强化期的变化。方法 收集广州市胸科医院20例初治菌阳肺结核患者使用强化方案治疗1周及强化期结束的粪便标本,所有标本进行16S rDNA测序,进行生物信息学分析。结果 强化期结束治疗组的Alpha多样性指标Chao1和observed_otus指数分别为(97.8±28.3)和(97.6±28.2),高于治疗1周组的(81±34.7)和(81±34.7),差异有统计学意义(P=0.04;P=0.038)。基于加权和未加权Unifrac距离的PCoA分析显示两组整体菌群结构无明显差异。在相对丰度较高的菌科中,强化期结束治疗组的拟杆菌科、肠球菌科、肠杆菌科、丹毒菌科、卟啉单胞菌科、双歧杆菌科等相对丰度下降,毛螺菌科、梭杆菌科、普氏菌科、瘤胃球菌科、韦氏菌科等相对丰度增加。通过线性判别分析效应量LEfse分析两组数据,发现在属水平上,厚壁菌门的瘤胃球菌、乳杆菌及放线菌门的柯林氏菌为组间显著差异菌种。结论 强化期治疗结束与治疗1周相比,肠道菌群多样性增加,但肠道菌群结构无明显差异。肠道拟杆菌科丰度减少,毛螺菌科丰度增加。

Objective To investigate the changes in the diversity and abundance of intestinal flora during the intensive period of anti-tuberculosis treatment. Methods Stool specimens from 20 patients with newly treated bacteria-positive pulmonary tuberculosis in Guangzhou Chest Hospital, which were treated with the intensive treatment for 1 week and whole intensive treatment, were collected. All the specimens were subjected to 16S rDNA sequencing and bioinformatics analysis. Results The Alpha diversity index Chao1 and observed_otus index of the treatment group with whole process were (97.8±28.3) and (97.6±28.2) respectively, which were higher than (81±34.7) and (81±34.7) of the 1-week treatment group, which had statistical differences (P=0.04;P=0.038). PCoA analysis based on weighted and unweighted Unifrac distance showed that there was no significant difference in the overall flora community structure between the two groups. Among the bacteria families with higher relative abundance, the relative abundance of Bacteroidaceae,Enterococcaceae,Enterobacteriaceae,Erysipelotrichaceae,Porphyromonadaceae and Bifidobacteriaceae in the treatment group with whole process decreased, the relative abundance content of Lachnodoiraceae,Fusobacteriaceae,Prevotellaceae, Rumincoccaceae, and Veillonellaceae increased. By using linear discriminant analysis effect size (LEfse) to analyze the two sets of data, it was found that at the genus level,Rumincoccaceae of Firmicutes and Lactobacillus;Collinsella of Actinobacteria were significantly different species between the groups. Conclusion Compared with 1 week of treatment, the diversity of intestinal flora increased at the end of intensive treatment, but there was no significant difference in the community structure of intestinal flora. The abundance of intestinal Bacteroidaceae decreased, and the abundance of Lachnodoiraceae increased.

目的 探索两种常用免疫学指标—结核菌素试验(purified protein derivative skin test, PPD皮试)与结核分枝杆菌γ-干扰素释放试验(tuberculosis-interferon gamma release assay,TB-IGRA)对结核病的辅助诊断价值。方法 收集2017年1月—2021年1月于我中心门诊部就诊的疑似结核病患者资料,共171例,所有病例均行PPD皮试和外周血TB-IGRA。将病例分为结核病组(TB组)和非结核病组(非TB组)。TB组共98例,非TB组共73例。比较两组病例PPD皮试、TB-IGRA对结核病诊断的准确度、敏感度、特异度。结果 TB-IGRA对结核病诊断的准确度、敏感度和特异度分别为94.2%、93.9%和90.4%,PPD皮试对结核病诊断的准确度、敏感度和特异度分别为77.2%、84.7%和76.7%。TB-IGRA的准确度和特异度与PPD皮试比较差异有统计学意义(分别为χ²=20.034,P<0.05和χ²=5.176,P<0.05);TB-IGRA的敏感度高于PPD皮试,但两者比较差异无统计学意义(χ²=0.948,P>0.05)。2组间TB-IGRA结果、PPD皮试结果比较差异均具有统计学意义(分别为χ²=132.77,P<0.01和χ²=47.963 5,P<0.01)。结论 TB-IGRA和PPD皮试均具有良好的结核病辅助诊断价值;TB-IGRA的引进大大提高了诊断试验的准确度和特异度,但仍需要进一步探索其诊断标准以更好地为临床使用。

Objective To explore the auxiliary diagnosis value of two commonly used immunological indicators for tuberculosis, purified protein derivative skin test (PPD test) and tuberculosis-interferon gamma release assay (TB-IGRA). Methods A total of 171 cases of suspected tuberculosis patients who were treated in the outpatient department of our center from January 2017 to January 2021 were collected. All cases underwent PPD test and peripheral blood TB-IGRA. The cases were divided into tuberculosis groups (TB group) and non-tuberculosis group (non-TB group). There were 98 cases in the TB group and 73 cases in the non-TB group. The accuracy, sensitivity, and specificity of PPD test and TB-IGRA for tuberculosis diagnosis were compared between the two groups. Results The accuracy, sensitivity, and specificity of TB-IGRA for tuberculosis diagnosis were 94.2%, 93.9% and 90.4% respectively, which of PPD test for tuberculosis diagnosis were 77.2%, 84.7% and 76.7% respectively. The accuracy and specificity of TB-IGRA were statistically different from those of PPD test (χ²=20.034,P<0.05 and χ²=5.176,P<0.05, respectively). The sensitivity of TB-IGRA was higher than that of PPD test, but the difference was not statistically significant (χ²=0.948,P>0.05). The differences of TB-IGRA and PPD test results between the two groups were statistically significant (χ²=132.77,P<0.01 and χ²=47.9635,P<0.01). Conclusion Both TB-IGRA and PPD test had good auxiliary diagnostic value for tuberculosis; the introduction of TB-IGRA had greatly improved the accuracy and specificity of the diagnostic test, but it is still necessary to further explore its diagnostic criteria to better serve the clinical use.

Objective To investigate the optimal dose of butorphanol in the treatment of shivering in patients underwent cesarean section. Methods A total of 150 women with cesarean section in our hospital from October 2019 to November 2020 were selected as the research objects, and were divided into group A, group B and group C according to random number table method, with 50 cases in each group. Group A was given 0.01 mg/kg butorphanol intravenously, group B was given 0.02 mg/kg, and group C was given 0.03 mg/kg. Clinical efficacy, hemodynamics, sedation (Ramesay) scores, adverse drug reactions (ADR) and neonatal Apgar scores were compared among the three groups. Results There were no significant differences in effective rate, hemodynamics, Ramesay scores at T₁ and T₂ time periods and Apgar scores of neonates at 1 min, 5 min and 10 min among the three groups (P>0.05). The incidence of ADR in group C was higher than that in group B and A (P<0.05). Ramesay score at time of T₃ of group C was lower than group B and group A (P<0.05). Conclusion The 0.02 mg/kg dose of butorphanol in the treatment of perioperative shivering in cesarean section was the most ideal dose, perioperative hemodynamics of puerpera was stable, adverse reactions were mild, and there was no obvious influence on neonates.

Objective We analyzed the molecular epidemiology of A.baumannii isolated from 5 teaching hospitals in Guangzhou to identify the epidemic clone in this area. Methods A total of 138 strains of A.baumannii were collected from 5 teaching hospitals, and the genetic relationship was evaluated by multilocus sequence typing (MLST) and eBURST algorithm. Results MLST divided 138 strains of A.baumannii into 8 existing sequence types (STs), namely ST195, ST208, ST457, ST136, ST254, ST548, ST445 and ST53, and 17 new STs. Among them, ST195 had the largest number, accounting for 35.5% (49/138) of all isolates, followed by ST208, accounting for 21.0% (29/138) of all isolates. eBURST algorithm showed that the clonal complex (CC) 195, the predicted founder ST195, was widely spread in the hospital environment. Conclusion A.baumannii CC195 was an epidemic clone in Guangzhou area. Medical institution should develop infection prevention and control strategies according to its own actual conditions.

目的 对冠心病治疗过程中出现迷走神经反射的原因进行分析探讨,并进行高效防治措施的总结。方法 本研究采用现况研究进行调查。本研究以在本院2021年1月—2021年3月就诊并临床诊断为冠心病的患者作为研究对象,经过纳入、排除标准筛选,共挑选出240名患者作为研究对象。根据文献分析得知拔鞘管可能是影响冠心病介入治疗过程中出现迷走神经反射的重要原因,因此将研究对象分为2组,实验组130人,对照组110人。对2组患者进行冠状动脉腔内血管成形术+支架置入术。实验组在患者进行鞘管拔出时进行局部麻醉;对照组则按照常规方法对鞘管进行拔出,分析2组患者迷走神经发生反射的几率,运用统计学软件进行数据分析对比。结果 根据数据分析结果可知,2组患者出现迷走神经反射的几率并不相同,通过差异性分析可知2组数据的差异具有统计学意义,且观察组发生率低于对照组(P<0.05)。结论 建议在临床上对冠心病进行介入治疗时,拔除鞘管的过程应该加入合理的干预,以减少患者出现迷走神经反射的几率,增强患者预后。

目的 本文主要对接受两种不同的甲氨蝶呤治疗方式与腹腔镜保守治疗输卵管妊娠患者治疗效果进行比较,了解不同治疗方案所具有的优势。方法 选择参与者为收治的输卵管妊娠患者200例(时间选择:2018年1月—2020年12月),以治疗方案进行分组(共2组,各100例)。对照组进行腹腔镜下输卵管线性切开术治疗,术中应用甲氨蝶呤治疗;研究组在术前进行甲氨蝶呤肌注,48小时后进行腹腔镜输卵管线性切开术治疗;比较治疗结果。结果 2组输卵管通畅率、术后持续异位妊娠率比较有差异,2组比对有统计学意义(P<0.05)。 2组手术指标(手术时长、术中出血量、β-hCG恢复至正常时间)比较有差异,2组比对有统计学意义(P<0.05)。结论 输卵管妊娠患者选择腹腔镜下输卵管线性切开术治疗时联合术前肌注甲氨蝶呤或术中应用甲氨蝶呤治疗,均可有助于输卵管妊娠症状的进一步缓解。但在此次治疗中患者术前接受甲氨蝶呤肌注+腹腔镜输卵管线性切开术联合治疗取得的疗效比常规的术中应用甲氨蝶呤更具有治疗优势,患者手术时长明显缩短,术中出血量明显降低,有效的避免反复电凝止血造成对输卵管造成的伤害,对输卵管功能进行有效保护,可推广。

目的 探讨急性胆囊炎患者术后胆管损伤发生的诊治及影响因素分析。方法 随机选取2019年3月—2020年6月经腹腔镜胆囊切除术后发生胆管损伤的86例急性胆囊炎患者作为观察组,另选同期腹腔镜胆囊切除术治疗未发生胆管损伤的56例患者作为对照组,观察2组患者的影响因素将其进行对比分析。结果 2组患者病历资料中的胆囊壁厚度≥ 4 mm、Calot三角充血、Calot三角水肿经统计学分析有差异(P＜0.01);手术情况中比较发现,胆囊三角区的解剖变异、术中操作不当、术中经验不足情况,经统计学分析有差异(P＜0.05);胆囊壁厚度≥ 4 mm、Calot三角充血、Calot三角水肿、胆囊三角区的解剖变异、术中操作不当、术中经验不足均为急性胆囊炎术后胆管损伤的独立影响因素(P＜0.05)。结论 急性胆囊炎患者术后发生胆管损伤的影响因素较多,应制定精准化的手术方案,在最大程度上减少胆管损伤的发病率,从而确保手术的安全性。
