目的 探讨利拉鲁肽与二甲双胍对新诊断2型糖尿病患者骨代谢的影响。方法 选取2016年1月—2017年6月在我院就诊并确诊为新诊断2型糖尿病患者50例,按照随机数字表法将研究对象随机分为利拉鲁肽组及二甲双胍组,每组各25人。两组患者均单药治疗24周后比较两组患者骨密度、骨代谢指标变化情况。结果 两组患者骨密度、血清ALP以及BGP、PINP水平治疗前后相比,无改变(P>0.05);而利拉鲁肽组患者的β-CTx水平较治疗前降低(P<0.05);两组患者治疗后FPG、2hFPG、HOMA-IR、HbA1c均较治疗前下降(P<0.05),而空腹胰岛素较治疗前上升(P<0.05);利拉鲁肽组患者治疗24周后BMI值低于治疗前(P<0.05)。结论 利拉鲁肽与二甲双胍对新诊断2型糖尿病患者骨密度的影响均不明显,两种药物可有效降低血糖,改善胰岛素抵抗,利拉鲁肽在使用过程中可明显降低患者血清β-CTx水平,但其是否存在骨质保护作用仍需进一步研究。

Objective To explore the effect of liraglutide and metformin on bone metabolism in newly diagnosed type 2 diabetic patients. Methods From January 2016 to June 2017, 50 patients with type 2 diabetes mellitus admitted to our hospital were selected. According to the random number table method, the subjects were randomly divided into liraglutide group and metformin group, 25 in each group. Changes in bone mineral density and bone metabolism were compared between the two groups after 24 weeks of monotherapy. Results That there was no significant change in bone mineral density, serum ALP, TPINP,and BGP levels before and after treatment (P>0.05). The β-CTx levels in patients in the liraglutide group were lower than that before treatment (P<0.05); FPG, 2hFPG, HOMA-IR, and HbA1c levels in the two groups were lower than that before treatment (P<0.05). Fasting insulin was higher than that before treatment (P<0.05); BMI was lower in the liraglutide group after 24 weeks of treatment than that before treatment (P<0.05). Conclusion The effects of liraglutide and metformin on the bone mineral density of patients with newly diagnosed type 2 diabetes are not obvious. Liraglutide may reduce serum β-CTx levels during use. We need to have further study whether it has a bone protection.

宫内发育迟缓(IUGR)又称小于胎龄儿(SGA),不仅影响近期健康,且对远期健康和生长发育具有重要影响,成年后2型糖尿病、肥胖、高血压、冠心病等代谢综合征的发病率明显增高。可能的机制是在生命早期个体对不利的刺激高度敏感,产生基因表达的异常,影响内分泌系统,从而对某些器官的结构或功能产生长期或永久性的影响。我们需从做好产前母体的营养与健康管理、小于胎龄儿出生后的系统管理、喂养选择纯母乳喂养等措施减少疾病的发生。

Intrauterine growth retardation (IUGR), also known as the small for gestational age (SGA), not only affects the recent health and has an important influence on long-term health and growth development. They are more easy to get the metabolic syndrome such as adult metabolism of type 2 diabetes, obesity, hypertension, coronary heart disease. Possible mechanism is produced in the early life of individual, is highly sensitive to adverse stimuli gene expression abnormalities which affecting the endocrine system, thus it have a long-term or permanent impact on the structure and function of some organs. We need to do more in prenatal maternal nutrition and health management, system management of SGA infants, pure breast feeding. Thus these could reduce the occurrence of metabolic syndrome.

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.

Objective To study the prevalence and correlation between the metabolic syndrome MS (including hypertension, diabetes, hyperlipidemia and obesity) with cardiovascular and dementia in the elderly people of south China. Methods This cross-sectional research studied metabolic syndrome of the elderly in south China. We collected the demographics and chemotic data and compared them in MS and non-MS group. And Logistic regression was used to analyze the independent factor of MS and the relationship between MS and the cardiovascular disease and dementia. Results This study included 206 patients and 92 (44.66%) of them were diagnosed as MS. 35 patients (38.04%) in MS group were female and 28 female cases (24.56%) in non-MS group. The mean age of the sample was (86.74±6.10) and the comparison between the MS group (86.37±5.74) and non-MS group (87.04±6.38) was not significantly different. White blood cell (WBC) (7.46±2.38 vs 6.46±2.35,P=0.003) and serum creatinine (Scr) was significantly [94.50(68.50,129.33) vs 78.00(64.50, 99.75),P=0.004]in MS group versus in non-MS group. Single factor and Multinomial logistic regression found WBC, serum creatinine and female gender were the independent risk factors of MS. Myocardial infarction (35, 38.04%) and angina (28, 24.56%) were significantly higher in MS group than that in non-MS group (10, 8.77%) and (39, 34.21%), respectively, with P<0.05. Logistic regression found MS was an independent risk factor of myocardial infarction and angina but not in heart failure and stroke. Dementia (including Alzheimer disease and vascular dementia) was found lower in MS group (26, 28.26%) than that in non-MS group (50, 43.86%), the difference was significant and this means MS could be protective for dementia. Conclusion MS is prevalent in the elderly of south China. Female gender, WBC and Scr were independent factors of MS; MS was the independent risk factor of myocardial infarction and angina; dementia was significantly lower in MS group, implying MS could be protective to dementia.
