基于苗药五藤膏外敷对CIA大鼠炎性骨破坏的影响探讨苗医外治就近驱邪的作用＊

目的 通过研究明确苗药五藤膏外敷缓解胶原诱导性关节炎（CIA）大鼠关节局部炎症和骨破坏的机制，证实苗医外治就近驱邪的作用。方法 将70只Wistar大鼠随机分为空白组、模型组、苗药五藤膏高、中、低剂量组、扶他林组及IL-17阻断组，每组10只。除空白组外，其余6组均构建CIA模型，并给予相应的外敷治疗。观察大鼠一般情况，HE染色进行病理学分析，TRAP染色检测OC生成，ELISA检测各炎症因子的含量，RT-PCR和WB分别检测RANKL的基因及蛋白表达。结果 苗药五藤膏能改善CIA大鼠破骨细胞浸润及关节病理性结构，并降低RANKL蛋白、基因表达以及TNF-α、IL-1、IL-6、IL-17含量。结论 苗药五藤膏外敷剂对CIA大鼠的治疗机制可能与降低致炎因子的分泌，抑制RANKL及OC的表达相关。     

Pure laparoscopic living donor liver transplantation: Dreams come true

Minimally invasive approaches are increasingly being applied in surgeries and have recently been used in living donor hepatectomy. We have developed a safe and reproducible method for minimally invasive living donor liver transplantation, which consists of pure laparoscopic explant hepatectomy and pure laparoscopic implantation of the graft, which was inserted through a suprapubic incision. Pure laparoscopic explant hepatectomy without liver fragmentation was performed in a 60-year-old man with alcoholic liver cirrhosis and hepatocellular carcinoma. The explanted liver was retrieved through a suprapubic incision. A modified right liver graft, procured from his 24-year-old son using the pure laparoscopic method, was inserted through a suprapubic incision, and implantation was performed intracorporeally throughout the procedure. The time required to remove the liver was 369 min, and the total operative time was 960 min. No complications occurred during or after the surgery. The patient recovered well, and his hospital stay was of 11 days. Pure laparoscopic living donor liver transplantation from explant hepatectomy to implantation was performed successfully. It is a feasible procedure when performed by a highly experienced surgeon and transplantation team. Further studies with larger sample sizes are needed to confirm its safety and feasibility.

     

非结核分枝杆菌肺病患者流行病学临床特点及耐药情况分析

目的分析95例非结核分枝杆菌肺病患者流行病学、临床特点及耐药情况。 方法从安徽省胸科医院2019年11月至2021年10月收治的非结核分枝杆菌肺病患者的临床病历资料中随机抽取95例进行回顾性分析，收集痰检样本完成菌种培养、鉴定及药敏试验。 结果检出非结核分枝杆菌阳性致病菌95株，其中胞内分枝杆菌(73.68%)；马萨分枝杆菌(1.05%)、马尔摩分枝杆菌(1.05%)。流行病学调查结果年龄30~65岁致病菌检出46例(48.42%)；>65~85岁致病菌检出49例(51.58%)。女性致病菌检出42例(44.21%)；男性致病菌检出53例(55.79%)。肺部影像学表现斑点或结节影(92.63%)、肺部双侧病变(80.00%)及临床症状中咳嗽(87.37%)。耐药性结果显示，非结核分枝杆菌整体对阿米卡星耐药性低，对盐酸乙胺丁醇耐药性高(P<0.05)。 结论非结核分枝杆菌肺病患者并未表现出显著的流行病学及临床特点，对于利福平、乙胺丁醇等一线抗结核药物存在不同程度的耐药。     

CT引导下经皮穿刺二次活检诊断肺部病变的可行性及安全性

目的 评价CT引导下经皮二次穿刺活检用于明确诊断肺部病变的可行性及安全性。方法 回顾性分析40例接受2次肺穿刺活检患者的临床、影像学及随访资料,根据最终诊断结果,比较2次活检的诊断准确率,分析并发症及初次活检误诊的危险因素。结果 40例中,17例初次活检诊断结果与最终诊断一致(确诊组)、23例诊断不一致(误诊组),诊断准确率为42.50%(17/40),并发症发生率为27.50%(11/40);39例二次活检诊断结果与最终诊断一致,诊断准确率为97.50%(39/40),并发症发生率为25.00%(10/40)。二次活检诊断准确率明显提高,并发症发生率与初次活检差异无统计学意义(P＞0.05)。组间病灶性质和气胸发生率差异均有统计学意义(P均＜0.05)。结论 CT引导下经皮二次穿刺活检用于明确诊断肺部病变安全、可行。
