肥胖相关脂肪性肝病的影响因素

随着饮食结构和生活方式的改变,肥胖症、嗜肝病毒感染和酒精滥用共同成为当代肝病的三大病因,肥胖症及其伴随的胰岛素抵抗直接参与非酒精性脂肪性肝病（NAFLD）及其重要类型脂肪性肝炎（NASH）的发病。全球尤其是亚太地区肥胖流行已成为近十年NAFLD患病率显著增加的主要原因,因此当前在很多国家,NAFLD已成为慢性肝病最常见原因。然而亚洲一些NAFLD患者通常并无肥胖,这可能与各种族间超重和肥胖的定义不同有关。另外,并非所有肥胖患者都并发脂肪肝。提示体内增多的脂肪对肝脏并非都有害,仅某些部位的脂质沉积易引起代谢紊乱和肝脏受损。     

Analysis of postoperative radiotherapy for non-metastatic head and neck adenoid cystic carcinoma based on SEER data

ObjectiveThe postoperative role of adjuvant radiotherapy in non-metastatic head and neck adenoid cystic carcinoma (ACC) remains controversial. We analyzed adjuvant radiotherapy’s effect on surgical patient survival.MethodsPatients diagnosed with ACC from 2004 to 2015 in the Surveillance, Epidemiology, and End Results database were analyzed. The overall survival (OS) and disease-specific survival (DSS) of patients after adjuvant radiotherapy were assessed using the Kaplan–Meier and multivariate Cox methods. Propensity score matching (PSM) was performed to adjust confounders between patients with or without adjuvant radiotherapy; a forest plot was generated by subgroup analysis.ResultsThe study included 742 patients. In the PSM cohort, adjuvant radiotherapy did not improve OS or DSS. Radiotherapy was not a protective factor for OS or DSS in the univariate and multivariate Cox proportional hazard models. In the subgroup analysis, postoperative radiotherapy improved the OS of female and N1-stage patients and those with oropharyngeal tumors or over 79 years and the DSS of N1-stage patients.ConclusionsPostoperative radiotherapy showed different benefits in ACC patients, and postoperative radiotherapy recommendations should be individualized. Female and N1-stage ACC patients and those with oropharyngeal tumors or patients over 79 years without distant metastases postoperatively could benefit from adjuvant radiotherapy.     

高血压和2型糖尿病对心脏搭桥术后早期心率变异性影响程度的探讨

目的：探究行非体外循环下冠状动脉搭桥术（off-pump coronary artery bypass grafting,OPCABG）患者围术期心率变异性（heart rate variability,HRV）的变化趋势,以及高血压和（或）2型糖尿病（type 2 diabetes mellitus,T2DM）因素对这种趋势的影响程度。方法：回顾性研究2020年12月至2022年3月因冠状动脉粥样硬化性心脏病需要行OPCABG的521名患者住院期间的基线资料与围手术期7 d动态心电图记录的相关指标来反映HRV的早期改变。根据患者既往是否患有高血压和（或）T2DM将患者分为A、B、C、D 4组：A组（患有高血压合并T2DM,n=118）、B组（单纯患有高血压,n=183）、C组（单纯患有T2DM,n=81）、D组（既往无高血压且无T2DM,n=139）。对521名患者行独立样本t检验,观察患者行OPCABG围术期全部窦性心搏RR间期的标准差（standard deviation of NN intervals,SDNN）与相邻正常心动周期差值的均方的平方根（root-mean-squa...

早发冠心病血运重建后临床危险因素及其与预后的相关性分析

目的：探讨早发冠心病（Premature coronary heart disease,PCHD）患者血运重建后临床危险因素及其与预后的关系,为PCHD血运重建后的健康干预及预后提供科学参考依据。方法：入选2000年2月1日至2010年1月31日我院接受冠脉介入治疗（Percutaneous coronary intervention,PCI）或冠状动脉旁路移植术（Coronary artery bypass graft,CABG）的2 134例患者,根据性别及年龄分为早发组和对照组（晚发组）,分析2组间一般情况、血液生化检验结果的差异,探讨PCHD患者血运重建后的临床危险因素。对PCHD血运重建术后患者组进行随访,用COX回归模型分析影响PCI或CABG术后预后的危险因素。结果：吸烟史、冠心病（Coronary heart disease,CHD）家族史和总胆固醇（Total cholesterol,TC）、甘油三酯（Triglyceride,TG）、纤维蛋白原及血红蛋白水平是PCHD血运重建后的临床危险因素,吸烟史及CHD家族史、血浆中TC偏高及血红蛋白偏低为PCHD术后预后的危险因素。结论：对于PCHD血运重建后患者,应针对性地对一些高危因素进行干预,加强控烟宣传及合理饮食指导,重视有阳性CHD家族史人群,对改善PCHD患者血运重建后发病及预后有一定参考意义。     

Altereporenes A–E,five epoxy octa-hydronaphthalene polyketides produced by an endophytic fungus Alternaria sp. YUD20002

Five previously undescribed epoxy octa-hydronaphthalene polyketides, altereporenes A–E (1–5) were isolated from rice culture of the endophytic fungus Alternaria sp. YUD20002 derived from the tubers of Solanum tuberosum. Their structures were determined on the basis of comprehensive spectroscopic analyses, while the absolute configurations were elucidated by the comparison of experimental and calculated specific rotations. Meanwhile, the antimicrobial, cytotoxic, anti-inflammatory and acetylcholinesterase inhibitory activities of compounds 1–5 were also investigated.
