野生动物学报, 2020 的：为了解黑龙江省和吉林省健康貉中大肠杆菌四环素耐药基因的分布情况，以貉源大肠杆菌为模板，检测四环素耐药基因，为控制耐药性奠定基础，有利于临床合理用药。方法：共选取56株貉大肠杆菌，通过PCR扩增靶基因以检测耐药基因的携带状态。 结果：四环素抗性基因tetM的检出率为82.14%，还检测到tetA、tetB、tetC、tetD，未检测出tetE。结论：大肠杆菌四环素耐药性可能由几种耐药基因共同介导。试验结果可为貉临床实践中合理使用四环素和预防四环素抗性出现提供理论依据。

基于术前炎症预后指数、预后营养指数构建IIIA-N2期非小细胞肺癌切除术预后风险模型的研究
Zhongguo shiyan zhenduanxue目的构建IIIA-N2期肺非小细胞癌切除术预后风险模型，并进行模型预测效能的验证与评估。方法进行回顾性队列设计，连续选取2022年1月至2025年1月海安市人民医院收治的接受切除术的IIIA-N2期非小细胞肺癌（NSCLC）患者130例。根据随访结果分为死亡组和生存组，比较两组患者的临床资料。采用Cox比例风险回归分析法明确独立危险因素，将独立危险因素引入R软件构建风险方程式，绘制Calibration曲线和受试者工作特征（ROC）曲线进行拟合度及预测效能评估，并绘制决策曲线（DCA）验证临床实用性 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2016 【目的】 探讨生长调节致癌基因－１（ＧＲＯ－１）在肝癌预后中的意义，同时初步研究其作用机制。【方法】 收集１７９例首次行根治性切除的肝癌患者的血清，根据收集病例的顺序，前１０３个病例进入检测组，后７６个病例进入验证组。应用人类细胞因子磁珠面板测定了血清中ＧＲＯ－１的表达水平。同时检测５株肝癌细胞系ＭＨＣＣ－９７Ｈ、ＱＧＹ－７７０３、ＳＭＭＣ７７２１、Ｈｅｐ３Ｂ及 ＣＲＩ２２３４中ＧＲＯ－１的分泌水平，并用ＭＴＳ及Ｔｒａｎｓｗｅｌｌ检测ＧＲＯ－１中和抗体对肝癌细胞增殖、迁移和侵袭的抑制作用。【结果 ...
