Objective To explore the prevalence of metabolic syndrome( MetS) and its components in patients with bipolar disorder and their lifestyle. Methods Collected 148 cases of bipolar disorder in patients with body mass index (BMI),blood glucose,blood pressure,triglyceride(TG),high-density lipoprotein( HDL-C) etc, and self-compiled scale was used to assess their lifestyle. All patients were followed 6 months. The patients werecompared with 65 normal controls. Results The patients group in the baseline period,treatment after 1 months,3 months and 6 months,the incidence of MetS was as followed:11.5% ,15.5% ,18.2% ,20.9%. The patients at all stages,the incidence of MetS,BMI≥25kg/m2 ,high TG levels,low HDL-C levels and hypertension were significantly higher than the control (P<0.01). After 6 months of treatment the incidence of MetS,hypertriglyceridemia were higher than baseline (P < 0.05). The patients group' s work intensity, frequency of exercise, eat more than 3 times per day compared with the control group were significantly different (P<0.01, P<0.05). Conclusion The incidence of MetS and hyperuricemia in patients with bipolar disorder after treatment is higher than the control group; as a continuation of the treatment,the incidence of metabolic abnormalities increased gradually. Unhealthy lifestyle, lack of exercise,unreasonable diet maybe increase the risk of metabolic disorders.

Aim To investigate the effects of midazolam on porcine isolated coronary artery rings pre-contracted by potassium chloride(KCl)and the possible mechanism.Methods The vessel tension recorder system was used.Isotonic tension of porcine isolated coronary artery rings precontracted by KCl(30 mmol·L-1)was recorded.The vasorelaxing action of midazolam and effects of various drugs were observed in the rings.Results Midazolam(3×10-6～1×10-4 mol·L-1)respectively concentration-dependently reduced the contraction induced by KCl,and there was significant difference between the rings with intact and denude endothelium(P<0.05).On KCl-induced precontraction,midazolam′s relaxation was depressed by L-NAME and the blend of L-NAME and L-Arg(P<0.05),but was not affected by Indo,L-Arg and 1400W.The contraction was not prevented by pretreatment with the inhibitor of Na+/Ca2+ exchanger(KB-R7943).The inhibitor of KATP(Gli)restrained the diastolic function of midazolam(P<0.05),while the inhibitor of BKCa(TEA),Kir(BaCl2),KV(4-AP)had no obvious effect.Conclusions Midazolam produces remarkable vasodilatation on KCl pre-contracted porcine isolated coronary artery rings.Its relaxtion effect is via concentration-dependent and endothelium-dependent mechanisms and relevant to the production of NO.Na+/Ca2+ exchanger is not involved midazolam′s vasodilatation on KCl pre-contracted porcine coronary artery rings.The relaxant mechanism of midazolam may be concerned with KATP.The Kir,BKCa and KV may be not involved.
