Cardioprotective effects of sinomenine in myocardial ischemia/reperfusion injury in a rat model

BackgroundIschemia reperfusion (I/R) play an imperative role in the expansion of cardiovascular disease. Sinomenine (SM) has been exhibited to possess antioxidant, anticancer, anti-inflammatory, antiviral and anticarcinogenic properties. The aim of the study was scrutinized the cardioprotective effect of SM against I/R injury in rat.MethodsRat were randomly divided into normal control (NC), I/R control and I/R + SM (5, 10 and 20 mg/kg), respectively. Ventricular arrhythmias, body weight and heart weight were estimated. Antioxidant, inflammatory cytokines, inflammatory mediators and plasmin system indicator were accessed.ResultsPre-treated SM group rats exhibited the reduction in the duration and incidence of ventricular fibrillation, ventricular ectopic beat (VEB) and ventricular tachycardia along with suppression of arrhythmia score during the ischemia (30 and 120 min). SM treated rats significantly (P < 0.001) altered the level of antioxidant parameters. SM treatment significantly (P < 0.001) repressed the level of creatine kinase MB (CK-MB), creatine kinase (CK) and troponin I (Tnl). SM treated rats significantly (P < 0.001) repressed the tissue factor (TF), thromboxane B2 (TXB2), plasminogen activator inhibitor 1 (PAI-1) and plasma fibrinogen (Fbg) and inflammatory cytokines and inflammatory mediators.ConclusionOur result clearly indicated that SM plays anti-arrhythmia effect in I/R injury in the rats via alteration of oxidative stress and inflammatory reaction.     

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.

     

MCI的情志病机及疏肝法干预的可行性探讨＊

轻度认知障碍（Mild cognition impairment， MCI）是尚未达到阿尔兹海默病（Alzheimer’s disease， AD）的诊断标准且可逆转为正常脑老化状态的最佳窗口期。情志异常、肝失疏泄（肝失疏泄日久致肝郁）已被证实为MCI的重要情志病机，且“长期负性情绪积累肝失疏泄致衰加速脑老化”的科学假说已在本课题组前期研究中得到初步证实，疏肝法干预肝郁型MCI患者疗效显著，但以上作用机制尚未得到完全阐述。因此本研究系统总结了中医学对MCI的认识，长期情绪不调肝失疏泄对MCI的影响及可能机制，疏肝解郁方药及其成分改善肝郁型MCI的可行性，并提出使用无束缚性设计的眼动技术以探索疏肝法改善肝郁型MCI的可行性，为MCI的中医药干预及其神经机制探讨提供新思路，为中医情志衰老学说增添新内涵。     

情绪释放技术对乳腺癌术后化疗患者预期性悲伤的影响

目的 探讨情绪释放技术对改善乳腺癌术后化疗患者预期性悲伤的效果。方法 采用便利抽样法选取乳腺癌术后化疗患者60例为研究对象,采用随机数字表法将其分为对照组和干预组,各30例。对照组给予常规护理,干预组在对照组的基础上实施情绪释放干预疗法。比较干预前后2组心理痛苦程度和预期性悲伤得分水平。结果 干预后,干预组心理痛苦程度低于对照组(t=-17.930,P＜0.001);预期性悲伤总分及各维度得分均低于对照组(P＜0.001)。结论 对乳腺癌术后化疗患者应用情绪释放技术进行护理干预,可以减轻患者心理痛苦程度,降低患者预期性悲伤,值得临床推广应用。     

改良眶隔法和传统睑板法切开重睑术的术后重睑形态、瘢痕发生率、角膜暴露率比较研究

目的 比较改良眶隔法和传统睑板法切开重睑术中的应用效果及对术后重睑形态、瘢痕发生率、角膜暴露率的影响。方法 选取2020年3月-2021年3月首都医疗爱育华医院收治的80例单睑患者，采用随机数字表法将其分对照组和观察组，各40例。对照组接受传统睑板法切开重睑术，观察组接受改良眶隔法切开重睑术，比较两组术后重睑形态、瘢痕发生率、角膜暴露率、并发症发生率。结果 观察组总有效率高于对照组，差异有统计学意义（P＜0.05）；观察组GAIS评分高于对照组，VAS评分低于对照组，差异有统计学意义（P＜0.05）；观察组右侧角膜暴露率增加值、左侧角膜暴露率增加值高于对照组，差异有统计学意义（P＜0.05）；观察组并发症发生率为5.00%，低于对照组的22.50%，差异有统计学意义（P＜0.05）。结论 相比于传统睑板法切开重睑术，改良眶隔法切开重睑术不会过度增加术后角膜暴露率，术后瘢痕发生率更低，重睑形态更理想，患者接受度更高。
