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.     

早产儿早期神经运动干预研究进展

增进积极体验为目标的健康干预对抑郁症病人抑郁情绪及生活质量的影响

目的:探讨增进积极体验为目标的健康干预对抑郁症病人抑郁情绪及生活质量的影响。方法:选择2019年9月—2021年3月在医院就诊的68例抑郁症病人为研究对象,按照随机数字表法分为观察组与对照组,每组34例。对照组予以常规护理,观察组在常规护理基础上予以增进积极体验为目标的健康干预。干预前后分别采用汉密尔顿抑郁量表(HAMD)、世界卫生组织生存质量测定量表简表(WHOQOL-BREF)评估病人的抑郁情绪和生活质量,同时对两组病人的护理满意度进行比较。结果:干预后观察组病人抑郁评分低于对照组(P<0.05);两组病人的生理功能、心理功能、社会功能及环境功能指标均较干预前有明显改善,且观察组评分均高于对照组(P<0.05);观察组病人对护理干预的总满意度为97.06%,高于对照组的61.76%(P<0.05)。结论:增进积极体验为目标的健康干预可明显缓解抑郁症病人的抑郁情绪,提高病人的生活质量。     

基于中国传统运动疗法的慢性筋骨病康复模式构建思路探析＊

中国传统运动疗法作为极具特色的康养健身运动疗法，在防病治病中的宝贵价值备受国际康复医学界关注。而慢性筋骨病是骨伤科临床中的常见病、多发病与疑难杂病，临床呈现出“一大五多五高”的特征，成为当前重大的健康问题与临床防治研究课题。本文通过深入探究中国传统运动疗法特点以及其在慢性筋骨病康复中的应用原理、原则及优势作用，提出以传统运动疗法为依托，构建慢性筋骨病防病治病应用方法模式；以三因制宜为指导，构建医院-社区-团体-患者为一体的康复管理模式；以“治未病”工程为支撑，构建慢性筋骨病管理信息资源共享平台模式；为切实提高防、控、治的能力与水平找准抓手与路径，为构建慢性筋骨病康复模式提供新的思路与方向。     

Perivascular fat attenuation for predicting adverse cardiac events in stable patients undergoing invasive coronary angiography

BackgroundInflammation surrounding the coronary arteries can be non-invasively assessed using pericoronary adipose tissue attenuation (PCAT). While PCAT holds promise for further risk stratification of patients with low coronary artery disease (CAD) prevalence, its value in higher risk populations remains unknown.MethodsCORE320 enrolled patients referred for invasive coronary angiography with known or suspected CAD. Coronary computed tomography angiography (CCTA) images were collected for 381 patients for whom clinical outcomes were assessed 5 years after enrollment. Using semi-automated image analysis software, PCAT was obtained and normalized for the right coronary (RCA), left anterior descending (LAD), and left circumflex arteries (LCx). The association between PCAT and major adverse cardiovascular events (MACE) during follow up was assessed using Cox regression models.ResultsThirty-seven patients were excluded due to technical failure. For the remaining 344 patients, median age was 62 (interquartile range, 55–68) with 59% having ≥1 coronary artery stenosis of ≥50% by quantitative coronary angiography. Mean attenuation values for PCAT in RCA, LAD, and LCx were ?74.9, ?74.2, and ?71.2, respectively. Hazard ratios and 95% confidence intervals (CI) for normalized PCAT in the RCA, LAD, and LCx for MACE were 0.96 (CI: 0.75–1.22, p ?= ?0.71), 1.31 (95% CI: 0.96–1.78, p ?= ?0.09), and 0.98 (95% CI: 0.78–1.22, p ?= ?0.84), respectively. For death, stroke, or myocardial infarction only, hazard ratios were 0.68 (0.44–1.07), 0.85 (0.56–1.29), and 0.57 (0.41–0.80), respectively.ConclusionsIn patients referred for invasive coronary angiography with suspected CAD, PCAT did not predict MACE during long term follow up. Further studies are needed to understand the relationship of PCAT with CAD risk.

Effectiveness of anabolic steroids in improving outcomes for post-operative hip fracture patients: A randomized controlled trial

BackgroundPost-operative elderly hip fracture patients require significant rehabilitation. Nandrolone is an anabolic steroid used to promote muscle growth. This study aims to examine the effect of nandrolone in improving rehabilitation and quality of life in elderly female patients with hip fractures undergoing hemiarthroplasty.MethodsThis is a double-blinded prospective randomized-controlled-trial consisting of female patients above the age of 65 with an isolated neck of femur fracture planned for a hip hemiarthroplasty. Participants were randomized into two arms of the study – 50 mg intramuscular nandrolone vs normal saline placebo administered on post-operative day 0, and weeks 2, 6 and 12. The participants were followed up across a 1-year period following the surgery. Clinical outcomes such as time taken to achieve rehabilitation milestones, distance of ambulation and thigh muscle girth, and functional scoring with SF-36 questionnaire were recorded at intervals of 2, 6 and 12 weeks, 6 months and 1 year following the surgery.ResultsThere were a total of 23 subjects with 11 in the steroid group and 12 in the placebo group. There was no significant difference in demographics and injury patterns between both groups. There was no significant difference for time taken to achieve various rehabilitation milestones and distance of ambulation. SF-36 scores on discharge and at 1-year follow-up mark were comparable. There was no difference in the complication rate between both groups.ConclusionIntra-muscular Nandrolone after hip surgery in elderly female patients does not result in short to mid-term improved rehabilitation or functional outcomes. Nandrolone did not result in increased short-term complications after hip surgery.Level of evidenceI.
