OBJECTIVE To investigate the effects of Compound troxerutin and poreine cerebroside injection on the activity of cytochrome P450 （CYP450） enzyme in vivo and in vitro. METHODS Human liver microsomes were incubated with Compound troxerutin and poreine cerebroside injection （volume fraction 0.05%-10%） and the specific probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6 and CYP3A4 for 30 min. The production of corresponding metabolites was detected by ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）， and the half inhibitory concentration （IC50） was calculated. The relative mRNA expression （i.e. induction multiple） of CYP450 enzyme was determined by real-time fluorescence quantitative PCR after human primary hepatocytes were incubated with Compound troxerutin and poreine cerebroside injection （volume fraction 0.05%-10%） or 3 positive inducers of CYP1A2， CYP2B6， CYP3A4 for 48 hours. Male SD rats were randomly divided into control group （normal saline+probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6， CYP3A4 8， 2， 1， 1， 10， 10， 8 mg/kg） and experimental group （Compound troxerutin and poreine cerebroside injection 0.9 mL/kg+probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6， CYP3A4 8， 2， 1， 1， 10，10， 8 mg/kg）， with 6 rats in each group. The pharmacokinetic parameters of probe substrates were detected by UPLC-MS/MS and Cocktail probe drug method. RESULTS After the lzqpharm@126.com treatment of 0.05%-10% Compound troxerutin and poreine cerebroside injection， the activities of CYP2B6， CYP2C8 and CYP2C19 in human liver microsomes had no significant change， and IC50 could not be fitted； IC50 of CYP1A2， CYP2C9， CYP2D6 and CYP3A4 were 419.90%， 97.78%， 176.00%， 19.42%， respectively. After the treatment of 0.05%-10% Compound troxerutin and poreine cerebroside injection， the average induction multiple of CYP3A4 mRNA in human primary hepatocytes （No. MHK） was 4.88 （and the average induction multiples of 2 concentration points were higher than 2）. After the treatment of Compound troxerutin and poreine cerebroside injection， AUC0－t and AUC0－∞ of CYP2C8， CYP2C9 and CYP2C19 substrates were increased significantly， CL of CYP2C8 and CYP2C19 substrates were decreased significantly， while t1/2 of CYP2C9 substrate was prolonged significantly （P＜0.05）. CONCLUSIONS Compound troxerutin and poreine cerebroside injection has no obvious inhibitory effect on CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6 and CYP3A4 in human liver microsomes in vitro， but can induce the mRNA expression of CYP3A4 in human primary hepatocytes in vitro， and can inhibit the activities of CYP2C8， CYP2C9 and CYP2C19 in rats in vivo.

The body weight, body mass index (BMI), chest circumference, waist circumference, hip circumference, insulin and blood lipids were observed before and after intervention.Result After intervention, body weight, BMI, waist circumference, waist-hip ratio, fasting insulin level, blood lipids, and insulin resistance dropped significantly in both groups (P<0.05); there were no significant differences between the two groups (P>0.05).Conclusion Acupoint thread embedding can reduce body weight and three circumferences, and modulate glucose and lipid metabolisms, through which approaching weight loss in a healthy way.

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.

BACKGROUNDBased 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.

METHODSThe 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.

RESULTSA 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%).

CONCLUSIONWe 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.
