Effectiveness of a nurse-led multidisciplinary self-management program for patients with coronary heart disease in communities: A randomized controlled trial

ObjectiveTo examine the effectiveness of a nurse-led multidisciplinary self-management program (NMSP) on self-management behaviors, self-efficacy, health-related quality of life (HRQoL) and unplanned health service utilization (HSU) among Chinese patients with coronary heart disease (CHD) in communities.MethodsA randomized controlled trial with repeated measurements was used. A convenience sample of 144 participants was recruited from a community health center in China. All participants were randomly assigned to an intervention group (n = 72) in the newly developed NMSP or a control group (n = 72) in routine care. Outcome measurement was performed at baseline, 3 months and 6 months using Coronary Artery Disease Self-Management Scale (CADSs), Self-efficacy for Chronic Disease 6-item Scale (SECD6), and Short Form-12 health survey questionnaire (SF-12).ResultsOver the six months, the two groups reported significant differences in disease medical and emotional management of CADSs, confidence in symptom and disease management of SECD6, physical and mental component summary of SF-12, as well as emergency and outpatient visits of unplanned HSU.ConclusionsThe NMSP improves self-management behaviors, self-efficacy, HRQoL and reduces unplanned HSU among CHD patients in communities.Practice implicationsThis study provides an effective approach to empower CHD patients with emphasizing on collaboration support of health professionals in communities.     

基于血清代谢组学技术考察通阳化浊方与四妙勇安汤治疗冠心病模型家兔的作用机制＊

目的 通过血清代谢组学技术，考察通阳化浊方与四妙勇安汤在治疗冠心病家兔中的作用机制。方法 40只雄性白兔，随机分为空白组、模型组、通阳化浊方组与四妙勇安汤组4组，每组10只。空白组正常饮食，模型组给予高脂饲料喂养至第8周，于第4周结束后，用球囊法手术损伤实验兔的右侧颈总动脉；在模型组基础上，两个实验组分别在术后，灌胃给予通阳化浊方和四妙勇安汤，连续4周，每日1次。给药结束后，模型组与实验组每组抽取3只家兔，采集全血后，用LC-MS技术进行血清代谢组学检测，运用PCA与OPLS-DA分析法来寻找差异性表达的代谢物和代谢途径。结果 相较于模型组，通阳化浊方与四妙勇安汤组分别存在45和27个差异化合物，通阳化浊方组涉及18条代谢通路，根据Impact值 > 0.05筛选出5条主要代谢通路，包括精氨酸和脯氨酸代谢、组氨酸代谢、牛磺酸和牛磺酸代谢、精氨酸生物合成和α-亚麻酸代谢；四妙勇安汤组涉及11条代谢通路，筛选出2条主要代谢通路分别为牛磺酸和牛磺酸代谢、组氨酸代谢。结论 通阳化浊方与四妙勇安汤在治疗冠心病模型家兔的过程中存在差异性代谢产物，干预相应的代谢通路可能会对药物在模型中的作用产生影响。     

Association between de novo lipogenesis susceptibility genes and coronary artery disease

Background and aimsCoronary artery disease (CAD) is the principal cause of death in individuals with non-alcoholic fatty liver disease (NAFLD). The aim of this study was to use genetic epidemiology to study the association between de novo lipogenesis (DNL), one of the major pathways leading to NAFLD, and CAD risk.Methods and resultsDNL susceptibility genes were used as instruments and selected using three approaches: 1) genes that are associated with both high serum triglycerides and low sex hormone-binding globulin, both downstream consequences of DNL (unbiased approach), 2) genes that have a known role in DNL (biased approach), and 3) genes that have been associated with serum fatty acids, used as a proxy of DNL. Gene-CAD effect estimates were retrieved from the meta-analysis of CARDIoGRAM and the UK Biobank (～76014 cases and ～264785 controls). Effect estimates were clustered using a fixed-effects meta-analysis. Twenty-two DNL susceptibility genes were identified by the unbiased approach, nine genes by the biased approach and seven genes were associated with plasma fatty acids. Clustering of genes selected in the unbiased and biased approach showed a statistically significant association with CAD (OR:1.016, 95%CI:1.012; 1.020 and OR:1.013, 95%CI:1.007; 1.020, respectively), while clustering of fatty acid genes did not (OR:1.004, 95%CI:0.996–1.011). Subsequent exclusion of potential influential outliers did reveal a statistically significant association (OR:1.009, 95%CI:1.000; 1.018).ConclusionsDNL susceptibility genes are associated with an increased risk of CAD. These findings suggest that DNL may be involved in the pathogenesis of CAD and favor further development of strategies that target NAFLD through DNL.

Prospect of Endoscopic Mucosal Resection for Early Gastric Cancer: Our Devices in Insulated‐Tip Electrosurgical Knife Method

In Kobe University Hospital, a new method for endoscopic mucosal resection (EMR) using insulated‐tip electrosurgical knife (IT‐EMR) for early gastric cancer (EGC) was introduced from November 2001. To achieve an effective and safe IT‐EMR procedure, we use a high‐frequency surgical unit for cutting and coagulation (ERBOTOM ICC 200) with automatically controlled cutting mode (ENDOCUT). In this study, we show not only our results of IT‐EMR for EGC in comparison with those of the conventional strip biopsy method, but also the optimal conditions for the apparatus of a high‐frequency surgical unit to prevent complications such as bleeding and perforation.     

冠状动脉瘘的诊治及新进展

冠状动脉瘘是一种罕见的冠状动脉畸形,绝大多数属于先天性畸形,极少数可由后天因素引起。由于冠状动脉血流向有关心腔、血管异常分流,导致引流部位负荷加重、瘘远端心肌缺血而引起相应临床症状。目前,绝大多数冠状动脉瘘已能由超声心动图明确诊断并可经内科介入技术或外科手术治愈。
