Objective To explore the correlation between metabolic syndrome (MS)and benign prostatic hyperplasia (BPH) and the drug treatment of BPH.Methods 300 cases of BPH patients treated between May 2011 to June 2012 in our hospital and Tong-Hai County hospitals of traditional Chinese medicine were included.The patients were divided into observing group (n=100) and control group (n=200).The observing group was treated with 5-alpha reductase inhibitors (finasteride).100 patients in control group-1 were treated with alpha-1 receptor blockers (terazosin).100 patients in control group-2 were treated with finasteride and terazosin.The changes of symptom scores,maximum urinary flow rate and prostate volume at month 3,month 6 and at end of a year after the treatment were compared among all groups.Results In 300 cases of BPH patients,there are 256 cases (85.3％) of MS+BPH,and 44 cases (14.7％) of simple BPH,with no statistically significant difference between the two groups in age and total cholesterol level (both P＞0.05).Among 256 cases of MS+ BPH,127 cases (49.6％) had diabetes,174cases (68.0％) had hypertension,85 cases (33.2 ％) had hypercholesterolemia or high triglyceride.The body mass index,blood pressure,fasting plasma glucose,IPSS gland volume were significantly higher (P＜0.05),and the maximum urinary flow rate was significantly lower in MS+BPH group than in the pure BPH group (P＜0.05).Prostate volume was positively correlated with age,body mass index,systolic blood pressure,fasting plasma glucose.IPSS score were positively correlated with age,body mass index,fasting blood glucose,total cholesterol.Maximum urinary flow rate were negatively correlated with age,fasting glucose,total cholesterol.At month 3 after treatment,the symptom score,maximum urinary flow rate were better in both of control group 1 and 2 than in the observation group (both P＜0.05).At 6 months after treatment,there was no statistically significant difference between the two groups in the symptom score,maximum urinary flow rate (both P＞0.05),while prostate volume was smaller in the observation group than in controls group 1 (P＜0.05).After a year of treatment,there were statistically significant differences in above indicators between the observe group and control group-1 (all P＜0.05),and had no statistically significant difference between the observe group and control group 2(all P＞0.05).Conclusions Most patients with BPH are suffering from MS at the same time.Body mass index,blood pressure,blood sugar,prostate volume,IPSS are higher in MS+BPH patients than in patients only with BPH.MS may affect the incidence and prognosis of BPH.Finasteride combined with terazosin can be used within 6 months,and finasteride can be used alone after 6 months of the drug therapy.

The effects of Na_2MoO_4 on experimental ventricular arrhythmias and isolated guinea pig atria are reported. Iv Na_2MoO_4, 8 mg/kg was found to increase the tolerant dose of ouabain to produce ventricular permature beats, ventricular tachycardia and ventricular fibrillation in guinea pigs. Na_2MoO_4 significantly counteracted the ventricular arrhythmias induced by BaCl_2 and aconitine in rats. Na_2MoO_4 10 ?g/10 g ip decreased the incidence of ventricular fibrillation by chloroform in mice, Na_2MoO_4 10 mg/kg did not produce antagonistic effect on the arrhythmias induced by chloroform-adrenaline in rabbits. Na_2MoO_4 0.1 mmol/L inhibited contractility of isolated guinea pig atria, prolonged the functional refractory period and makedly inhibited the frequency-dependent positive staircase phenomenon and the post-rest potentiation.

The antiarrhythmic actions of ZnSO4 (Zinc) were studied in ex-perimental arrhythmias models. ZnSO4 10mg/kg(iv) significantly coun-teracted the arrhythmias, induced by aconitine or BaCl2 rats.It was shown to shorten the duration of arrhythmias induced by chloroform-epinephrine in rabbits. In mice, ZnSO4 20 ?g/10g(ip) decreased the incidence of ventricular fibrillationbychloroform. However, ZnSO4 did not decrease the incidence of CaCl2-induced , venticular fibrillation, the threshold and lethal doseofouabain in producing ventricular permature beats, ventricular fibrillation in guinea pigs.

Zinc sulfate 0.1mmol/L inhibited the frequency dependent positive staircase phenomenon on isolated guinea pig atria. Ten min after adding zinc sulfate 0.1 mmol/L, the contractility of the left atrium decreased. The needed concentration of epinephrine inducing automaticity was increased and the functional refractory period(FRP) was prolonged from 192?5 ms to 247?4 ms ( P

OBJECTIVE: A series of studies has been reported concerning deep venous thrombosis following artificial hip replacement. This paper is aimed to summarize the occurrence factor and preventive measures for deep venous thrombosis following artificial hip replacement.METHODS: A computer-based online search of VIP database was undertaken by the first author to identify the articles about the deep venous thrombosis following artificial hip replacement published in between January 1994 and October 2009 with the key words of"artificial hip replacement and deep venous thrombosis". Inclusive criteria: ①Occurrence factor of deep venous thrombosis following artificial hip replacement. ②Diagnostic criteria and diagnostic methods of deep venous thrombosis following artificial hip replacement. ③Preventive strategy for deep venous thrombosis following artificial hip replacement. Inclusive criteria: repetitive research or obsolete documents. Totally 25 literatures were included in this paper.RESULTS: The agreement has been basically achieved for pathogenesis and risk factor of deep venous thrombosis following artificial hip replacement. The pathogenesis included blood hypercoagulable state, slow blood flow (or stasis), and vessel wall damage. Meanwhile, elderly, cerebrovascular disease, varicose vein or intravenous surgery, were the risk factors of deep venous thrombosis. Mechanical therapy or medication could be selected for preventing patients against deep venous thrombosis following artificial hip replacement with different features. It was an acceptable method for most patients using mechanical therapy, which could not induce drug adverse reaction, but the clinical efficacy remained uncertain for high-risk patient population, thus, medication should be combined. Low molecular heparin was considered first-choice drugs for preventing deep venous thrombosis following artificial hip replacement, which was characterized by common uses and reliable effects. CONCLUSION: Studies on influencing factor and preventive treatment of deep venous thrombosis following artificial hip replacement has arisen more attention in medical circles. The understanding of pathogenesis, correlation factors and preventive measures plays an important role in decreasing incidence deep venous thrombosis.

The effects of FeSO_4 upon the physiologicproperties were studied with isolated guinea pig a-trium. The FeSO_4 0. 2mmol/L, makes the contrac-tility of the atrium muscle decrease from 100% ofcontrol to 67 ? 9%. The concentration ofepinephrine inducing automaticity increased andthe duration-intensity curve was shifted to theright. The functional refractory period (FRP) wasprolonged from 298 ? 26 ms to 402 ? 43 ms. Thenegative inotropism and the inhibition of the auto-maticity suggest that FeSO_4 may influence Ca~(2+)movement, while the excitability of suppressionand prolongation of FRP indicate that it may bedue to its inhibition of Na~+ influx.

Objective To investigate the relaxant effect of salanic acid A isopropyl ester(isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate)and its mechanism.Methods Isolated rat pulmonary artery was perfused and the tension of the vessel was measured.To observe the relaxant effect of salianic acid A isopropyl ester on the pulmonary artery precontracted by noradrenaline(NE)and the role of endothelial cell and vascular smooth muscle cell on vasodilation.Results Salianic acid A isopropyl ester relaxed the endothelium-intact artery precontracted by NE in a concentration-dependent manner,and the effect was depressed with denuded endothelium.Salianic acid A isopropyl ester right-shifted the concentration-response curve of KCl and suppressed the contractions induced by NE and CaCl2 in the Ca2+-free-K-H solution.The relaxant effect of salianic acid A isopropyl ester was inhibited by N?-nitro-L-arginine methyl ester hydrochloride(L-NAME),Indometacin,CsCl,Tetraethylammonium(TEA),Glibenclamide,and BaCl2,but not that by Propranolol,Metoprolol,and Salbutamol.Conclusion Salranic acid A isopropyl ester could significantly relax the pulmonary artery of rats,which may derive in part from endothelium.The relaxant effect of salianic acid A ispropyl ester may relate to NO pathway,prostacyclin(PGI2)pathway,calcium channel,and potassium channel.
