血脂代谢紊乱与腹膜透析置管大网膜包裹的关系

目的探讨血脂代谢紊乱和腹膜透析置管术后发生大网膜包裹的关系。方法选择中南大学湘雅医院肾内科收集腹膜透析置管术后发生大网膜包裹病例15例,以同期未发生大网膜包裹病例30例为对照,对比二组发生血脂代谢紊乱的差异。同时,以是否存在血脂代谢紊乱分组,对比腹膜透析置管术后大网膜包裹的发生率。结果大网膜包裹组的三酰甘油（TG）、胆固醇（CHO）和低密度脂蛋白（LDL）明显高于非大网膜包裹组;大网膜包裹组载脂蛋白A1（APOA1）水平则低于非大网膜包裹组。结论血脂代谢紊乱与腹膜透析置管术后发生大网膜包裹相关,可能是易于发生大网膜包裹的一个危险因素。     

肥胖患者椎管内麻醉后低血压的危险因素及预测的有效性

目的探讨肥胖患者椎管内麻醉后发生低血压的危险因素,评估肥胖相关指标预测椎管内麻醉后低血压的效果。方法选取2018年6月至2019年6月在本院择期行椎管内麻醉手术肥胖患者228例,男115例,女113例,年龄18～70岁,BMI≥24 kg/m~2,ASAⅠ或Ⅱ级。根据患者椎管内麻醉后仰卧位10 min内是否发生低血压分为两组:低血压组和非低血压组,低血压定义为MAP下降幅度超过基线值的20%。采用二元logistic回归分析肥胖患者椎管内麻醉后发生低血压的危险因素,并用受试者工作特征曲线(ROC)计算肥胖相关测量指标对椎管内麻醉后低血压的预测效果及阈值。结果共有97例(42.5%)患者椎管内麻醉后发生低血压。其中血脂异常(OR=3.593,95%CI 1.974～6.541)和腹型肥胖(OR=1.980,95%CI 1.068～3.668)是肥胖患者椎管内麻醉后发生低血压的独立危险因素。在肥胖相关测量指标中,腰围对肥胖患者椎管内麻醉后低血压的预测效果最优,男性患者阈值为87.5 cm,敏感性92.9%,特异性81.4%。女性患者阈值为83.5 cm,敏感性89.6%,特异性93.8%。结论术前重视肥胖患者的血脂及腰围可以有助于预测椎管内麻醉后低血压。     

新疆维吾尔族成人血脂流行特点分析

目的调查新疆维吾尔族成人血脂流行特点。方法采用多级整群抽样调查,于2007年10月至2008年1月,测定1283名维吾尔族居民的TG、TC、HDL—C、LDL—C。结果血脂异常总患病率为49．4％,其中男性患病率为54．7％、女性患病率为44．5％,低HDL—C患病率最高,为37．6％。60岁以上的老年患者是血脂异常的高发人群。超重、向心性肥胖、高血压及糖尿病均与血脂异常相关。结论新疆维吾尔族成人血脂异常患病率高,防治工作应侧重于老年人,建议合理膳食、增加体育运动、降低体重以及控制烟酒,并注意高血压、糖尿病等多种危险因素的防治。     

Comparison of serum lipid profile in type 2 diabetes with and without adequate diabetes control in Sudanese population in north of Sudan

Background

Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. Dyslipidemia is a major complication of diabetes and an important risk factor for cardiovascular disease (CVD). The objective of this study was to determine the prevalence of dyslipidemia and its co-relation with the glycemic control in individuals with diabetes in River Nile State, Sudan.

Intravascular evaluation of coronary atherosclerotic lesions among Egyptian diabetic patients with acute coronary syndromes

Background

Coronary artery disease is one of the main causes of death in diabetes mellitus (DM). Egypt was listed among the world top 10 countries regarding the number of diabetic patients by the International Diabetes Federation (IDF).

健康体检者胰岛素抵抗与血脂异常的相关性及血脂最佳分界值的探讨

目的 分析健康体检者胰岛素抵抗（IR）与脂代谢异常之间的相关性,并探讨应用甘油三酯/高密度脂蛋白胆固醇（TG/HDL-C）预测IR的最佳分界值。方法 选取2014年5月~7月于河北省人民医院体检中心体检者785名纳入本研究,按照不同性别将研究对象分别以胰岛素抵抗指数（HOMA-IR）中位数2.02为界限,分为胰岛素抵抗（IR）组和胰岛素敏感（IS）组,比较两组体格检查指标及生化指标,并分析IR与血脂异常的相关性。应用ROC曲线探讨TG/HDL-C预测IR的最佳分界值。 结果 两组男性和女性空腹血糖（FBG）、总胆固醇（TC）、TG、HDL-C、低密度脂蛋白胆固醇（LDL-C）水平及TG/HDL-C比较,差异有统计学意义（P＜0.05）。Spearman相关分析显示,HOMA-IR与FBG、TC、TG、LDL-C、TG/HDL-C呈正相关（P＜0.05）,与HDL-C呈负相关（P＜0.05）。Logistic回归分析结果显示年龄、体重指数（BMI）、腰围（WC）、FBG、TG及HDL-C是IR的危险因素。ROC曲线结果提示预测男性健康体检者IR发生风险的TG/HDL-C为1.24（AUC:0.748,95%CI:0.704~0.792）,敏感性为64.80%,特异性为75.90%;预测女性健康体检者IR发生风险的TG/HDL-C为1.36（AUC:0.728,95%CI:0.670~0.785）,敏感性为58.00%,特异性为79.70%。结论 IR与血脂异常具有相关性,尤其和TG、HDL-C密切相关。TG/HDL-C可以作为预测健康体检者IR的一个指标。     

Risk factors associated with the development of ischemic colitis

AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence
