Improvement of Suoquan Capsules on bladder function of diabetic mice / 中成药

AIM To investigate the improving effect of Suoquan Capsules (Linderae Radix,Alpiniae oxyphyllae Fructus and Dioscoreae Rhizoma) on mice with diabetic cystopathy and its mechanism of action.METHODS Sixty mice were randomly assigned into normal group (n =8) and model group (n =52);the diabetic models of the latter were induced by high-fat feeding combined with streptozotocin (STZ) injection,then modeled mice (n =32) were randomly divided into model,Mecobalamin Tablets,low-and high-dose Suoquan Capsules groups.The influences of Suoquan Capsules on fasting blood glucose (FBG),glycated serum protein (GSP) level and general conditions were observed.The bladder leak point pressure (BLPP) was determined.Histopathological staining was performed on urinary bladder.And the expressions of substance P and NK1 receptor were detected by double immunofluorescent staining.RESULTS There were no significant differences in FBG,GSP,body weight,food intake and water consumption among various groups.The high-dose Suoquan Capsules significantly decreased urine volume of mice.Compared with the model group,the treatment with Suoquan Capsules markedly increased BLPP,the expressions of substance P and NK1 receptor were significantly increased,and the histopathology of bladder in mice was obviously improved.CONCLUSION Suoquan Capsules improves the diabetic cystopathy in mice,and its mechanism maybe related to the up-regulation of substance P and NK1 receptor expressions in bladder tissue.

Clinical study of rociverine tablets combined with Suoquan capsules in the treatment of female patients with overactive bladder syndrome / 中国基层医药

Objective To assess the efficacy and safety of combining rociverine tablets with Suoquan cap-sules in the treatment of female patients with overactive bladder(OAB).Methods 152 female patients with OAB were randomly divided into three groups.Patients in rociverine group were administered rociverine tablets 10mg three times a day for 4 weeks.Patients in Suoquan capsule group were administered Suoquan capsules 1.8g three times a day for 4 weeks.Patients in combination group were administered rociverine tablets 10mg and Suoquan capsule 1.8g three times a day for 4 weeks.Each group of patients had to complete 3d voiding diary before and after treatment to record daily frequency of micturition,urgency,urgency incontinence,nocturia and avoiding volumes,OABSS score and drug side effects were also observed.All the data were analyzed to assess the efficacy and safety of treatment.Results There were significant differences in daily frequency of micturition,urgency,urgency incontinence,nocturia,avoiding volumes and OABSS score of patients in each group before and after treatment(all P 0.05).The incidence rates of adverse events of rociverine and combination group were 7.8% and 22.6%,respectively,there was significant difference between the two groups(χ2 =4.372,P =0.032). Conclusion Combining rociverine tablets with Suoquan capsules in the treatment of female patients with OAB was effective and safe.

Determination of Norisoboldine in Suoquan Capsules by HPLC / 中国药师

Objective:To establish an HPLC method for the determination of norisoboldine in Suoquan capsules. Methods: The chromatographic procedure with acetonitrile-water containing 0. 5% folic acid and 0. 1% triethylamine (10∶90) as the mobile phase was carried out on an Ecosil C18 HPLC(150 mm ×4.6 mm,5 μm). The flow rate was at 1.0 ml·min-1, the detection wavelength was 280nm and the column temperature was 30 ℃. Results: The linear range of norisoboldine was within 38. 56-578. 40 ng ( r =0. 999 2), the average recovery of norisoboldine was 99. 9%(RSD=1. 7%, n=6). Conclusion:The method is highly sensitive, re-liable and accurate, and can be applied in the determination of Suoquan capsules.
