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.

OBJECTIVETo develop a tumor imaging agent for vasoactive intestinal peptide (VPAC) receptor and evaluate its biological activity and pharmacokinetics of radiolabeled peptide.

METHODSVIP(28) was modified at the carboxyl terminal by the addition of His-tag which was the chelating site of (99m)Tc(I) and the general purification tag for immobilized metal ion affinity chromatography. Biological activity of the modified VIP(28) analogue MY34 was examined in vitro by radiological cell-binding assay, rabbit internal anal sphincter (IAS) smooth muscle relaxing assay and immunocytochemical stain. The pharmacokinetics of this labeled peptide was examined in C57 mice.

RESULTSMY34 could relax the IAS smooth muscle and bind VPAC receptors on tumor cell membranes. (99m)Tc- MY34, with a yield of about 90%, was stable enough for practical use. Both MY34 and VIP(28) could inhibit the binding between the labeled peptide and VPAC receptor. The pharmacokinetics of [(99m)Tc(H(2)O)(3)(CO)(3)]-MY34 was studied in mice conformed well with the two-compartment model (Wi = 1/C(2)), with a t(1)/(2alpha) of 16.35 min and a t(1)/(2beta) of 1013.56 min.

CONCLUSIONMY34 possesses physiological activities and specific receptor binding characteristics similar to those of natural VIP(28).
