A balanced nutrition intake is essential for health as well as a speedy recovery of such wounds. The study objective was to compare chronic wound inpatients supplemented with food nutrient content with outpatients with their usual intake in a cross-sectional study. Patients’ food samples were taken for chemical analyses. The protein, beta-carotene, sodium, magnesium, manganese, and potassium content prove statistically significant differences. Outpatients’ diets are more diversified than inpatients’ diets, and supplementation diet richest in beta-carotene and in protein. Outpatients have better dietary diversity than those who were hospitalized. The result provides insights of supplementary food as critical issues pertaining to chronic wounds management. However, analyzing bioavailability of nutrient on patients’ blood may provide more knowledge in the appropriate integrated wound management.展开更多

糖基化血红蛋白（glycosylated hemoglobin）是伊朗科学家Ranbar等应用琼脂糖凝胶电泳分析率先从糖尿病患者血液中发现的一种血红蛋白组分，且研究表明，是血液葡萄糖对HbA的非遗传修饰产生了糖化血红蛋白A1c（haemoglobinA1c,HbA1c）[1...糖基化血红蛋白（glycosylated hemoglobin）是伊朗科学家Ranbar等应用琼脂糖凝胶电泳分析率先从糖尿病患者血液中发现的一种血红蛋白组分，且研究表明，是血液葡萄糖对HbA的非遗传修饰产生了糖化血红蛋白A1c（haemoglobinA1c,HbA1c）[1,2]。从此，他们与糖尿病的相关性得到确认，这一发现奠定了HbA1c检测用于糖尿病的初筛和诊断的基础。美国糖尿病控制及并发症试验（Diabetes Control and Complications Trial,DCCT）和英国前瞻性糖尿病研究（UK Prospeetive Diabetes Study,UKPDS）历时多年的糖尿病流行病学研究表明糖尿病患者通过治疗，控制平均血糖水平和HbA1c，能够有效地得到治疗，显著降低视网膜病变、肾脏疾病以及神经病变等并发症的发生及其严重程度。展开更多
文摘目的:观察7.5％氯化钠(NaCl)快速注入对出血性休克犬生化的影响。方法:取5条杂种犬,失血至平均动脉压5．33- 6.70kPa且维持此血压1h后,2min内静脉注入7．5％NaCl(4ml／kg),观察4h。分别于失血前、给药前．给药后30min、 给药后3h检查血钾(K+)、钠(Na+)、氯(Cl-)及肌酐(Cr)。结果:失血后Cr高于失血前(P<0．05)。给药后30 min K+较给药前低(P<0.05);Na+及Cl-均较给药前升高(P<0．01)．Na+最高者达到了219mmol／L;Cr无明显变化。给 药后3 h K+比给药后30 min明显升高(P<0．05);Na+、Cl-及Cr均无明显变化,其中Cr呈上升趋势。结论:7．5％ NaCl快速注入对出血性休克犬的生化有明显影响。
