Résumé
Objective To investigate the clinical significance of serum omentin-1 levels in obesity and essential hypertension patients and its related influencing factors. Methods One hundred and thirty patients with obesity admitted to the Cadre Health Care Department of Navy General Hospital from Jun. 2011 to Dec. 2013 were enrolled in this study. According to the blood pressure,130 obesity patients were divided into simple obesity group( n=64 )and obesity hypertension group( n=66 ). Sixty non obesity patients with normal blood pressure were enrolled as control group. Serum omentin-1 levels were assessed by enzyme linked immunosorbent assay ( ELISA). Association between omentin-1 and biochemical parameters( including systolic blood pressure( SBP), diastolic blood pressure(DBP),body mass index(BMI),waist hip ratio(WHR),fasting blood glucose(FBG), triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol( HDL-C),fasting insulin( FINS),insulin resistance index( HOMA-IR)and high sensitive C reactive protein(hs-CRP))were analyzed. Results Serum omentin-1 levels in control group was(26. 7 ± 5. 1)μg/L, significantly higher than that in simple obesity group and obesity hypertension group((22. 1 ± 3. 2)μg/L,(18. 3 ± 3. 4)μg/L;F=33. 7,P﹤0. 01),and serum omentin-1 levels in obesity hypertension group was significantly lower than that in simple obesity group( t =21. 5,P ﹤0. 05). Pearson correlation analysis showed that serum omentin-1 negatively correlated with BMI,WHR,SBP and HOMA-IR( r = - 0. 447,- 0. 340,- 0. 350,-0. 397;P﹤0. 01). There were no significant relations between omentin-1 and age,DBP,FBG,FBG,TG,TC, LDL-C,HDL-C,FINS and hs-CRP( P ﹥0. 05 ). Multiple stepwise regression analysis showed that HOMA-IR, BMI and SBP were independent influencing factors of serum Omentin-1. Conclusion The serum omentin-1 level decreases in the obesity hypertension patients. Omentin-1 is negatively correlated with BMI,SBP,and HOMA-IR, which may contribute to the underlying pathophysiology of obesity and essential hypertension.
Résumé
<p><b>BACKGROUND</b>Based on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.</p><p><b>METHODS</b>The Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.</p><p><b>RESULTS</b>A total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).</p><p><b>CONCLUSION</b>We first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.</p>
