目的 了解疫情期间医护人员代谢综合征(MS)、高同型半胱氨酸血症(HHcy)的患病率、二者关系及靶器官损害。方法 选取2020年1月—2021年11月在天津市某三级综合医院的1 544名医护人员作为研究对象。测量人体指标,测定血液生化、免疫等指标。分析MS及其组分的患病率、HHcy的患病率及靶器官损害。采用χ²检验,比较MS组、HHcy组与对照组靶器官损害的差异。采用Logistic回归模型分析MS与HHcy的关系。结果 三级综合医院医护人员疫情期间MS患病率为23.7%,MS组分:中心性肥胖、高血压/高血压病、高甘油三酯、低高密度脂蛋白和高空腹葡萄糖/糖尿病的患病率分别为49.4%、19.3%、24.3%、0.5%和37%。HHcy的患病率为29.7%。MS组、HHcy组与对照组靶器官损害程度差异有统计学意义(P<0.001)。HHcy与MS无直接相关性。结论 疫情期间医护人员MS和HHcy患病率较高,与对照组相比有明显的靶器官损害,HHcy不是MS的独立危险因素。

Objective To explore the prevalence of metabolic syndrome (MS) and hyperhomocysteinemia (HHcy), their relationship and target organ damage among medical staff during the pandemic. Methods A total of 1 544 medical staff in a third-class general hospital in Tianjin from January 2020 to November 2021 were selected as the object of study. The indexes of human body were measured, and the indexes of blood biochemistry and immunity were detected. The prevalence of MS and its components, the prevalence of HHcy and target organ damage were analyzed. χ² test was used to analyze the difference of target organ damage among MS group, HHcy group and control group. The relationship between HHcy and MS was analyzed by Logistic regression model. Results The prevalence of MS among medical staff in the third-class general hospital during the pandemic was 23.7%. The prevalence of central obesity, hypertension / hypertension disease, high triglyceride, low high density lipoprotein cholesterol and high fasting plasma glucose/diabetes were 49.4%, 19.3%, 24.3%, 0.5% and 37%, respectively. The prevalence of HHcy was 29.7%. There was significant difference in target organ damage among MS group, HHcy group and control group (P<0.001). There was no direct correlation between HHcy and MS. Conclusions During the pandemic period, the prevalence of MS and HHcy in medical staff were high, and there was obvious target organ damage in those staff compared with the control staff. HHcy is not an independent risk factor of MS.

瘦素是维持人体能量代谢平衡的蛋白质,在人体中主要由白色脂肪组织分泌,通过与瘦素受体结合发挥作用。近年来有许多与瘦素相关的研究证明高血压患者及代谢综合征患者的血清瘦素水平较健康人群明显升高。两种疾病均可出现心室肥厚,蛋白尿,动脉粥样硬化等表现,说明二者存在共同的靶器官。瘦素代谢异常可出现瘦素抵抗并通过影响肾素-血管紧张素-醛固酮系统(renin angiotensin aldosterone system, RAAS)及炎症细胞因子来损伤靶器官。本文旨在总结瘦素在高血压及代谢综合征中的作用机制,并探讨瘦素对高血压合并代谢综合征靶器官损伤作用的研究进展。

Leptin is a protein that maintains the balance of energy metabolism in human body. It is mainly secreted by white adipose tissue in human body. In recent years, many studies have shown that the serum leptin level in patients with hypertension complicated with metabolic syndrome is significantly higher than that of healthy people. Both of the diseases can lead to left ventricular hypertrophy, proteinuria, atherosclerosis and other manifestations. The abnormal metabolism of leptin may contribute to leptin resistance which damages target organs by affecting the angiotensin aldosterone system and inflammatory cytokines. The aim of this article is to summarize the mechanism of leptin in hypertension and metabolic syndrome, and to explore its effect on the target organ damage in patients with hypertension complicated with metabolic syndrome.
