Objective To observe the clinical efficacy of Ningmitai capsule combined with Tolterodine in the treatment of overactiver bladder after transurethral resection of the prostate(TURP).Methods 63 TURP patients with bladder disease (OAB) in our hospital from October 2012 to October 2012 were selected and randomly divided into a treatment group (n=32) and a control group (n=31). From the date of operation, the control group was treated with tolterodine 2 mg, 2 times a day, while the treatment group was additional treated with Ningmitai capsule 4mg, 3 times a day based on the control group. All patients stopped to take medicine 5 days after catheter removal. The pain frequency and duration of bladder spasm after TURP in catheterization period and the urine volume per time, the number of urgent incontinence, and the number of urgent micturition average day in automatic micturition period were scored by OABSS.Results The number of bladder spasm in the first postoperative day(3.5 ± 0.5vs.4.4 ± 0.8,t=2.650), the second day(1.5 ± 0.9vs.1.8 ± 0.2,t=2.350) and the third day (0.4 ± 1.6vs. 1.1 ± 1.8,t=2.210) of the treatment group were all less than the control group (P>0.05). The 24 h average frequency of urination after catheter removal (6.2 ± 1.3vs. 9.4 ± 1.8,t=2.710), the average number of nocturia (1.5 ± 0.4vs. 3.9 ± 1.0,t=2.580), the average number of 24h urinary urgency (1.1 ± 0.3vs. 3.2 ± 0.8,t=2.660), the average number of incontinence in 24 h (0.5 ± 0.2vs. 2.4 ± 0.6,t=2.700) and OABSS total score  (4.6 ± 1.2vs. 6.9 ± 2.1,t=2.470) of the treatment group were all better than the control group (P<0.05). Conclusion Ningmitai capsule combined with tolterodine in the treatment of overactiver bladder after TURP has significant clinical effect, helping patients recovery and improving quality of life.

Objective To optimize the process of extracting total saponins from Platycodon grandiflorum by orthogonal experimental design and central composite design-response surface method. Methods Independent variables were concentration of ethanol, reflux extraction time, reflux time and solvent fold. Dependent variables were extraction rate of total saponins in Platycodon grandiflorum and the yield of dry extract.Linear or nonlinear mathematic models were used to estimate the relationship between independent and dependent variables. Results The result of the orthogonal experimental design was 70%ethanol, 180 min for reflux, 6 fold of solvent and 2 times for extraction. The result of central composite design-response surface method was 70% ethanol, 140 min for reflux, 10 fold of solvent and 2 times for extraction. Conclusion The central composite design-response surface method is better than orthogonal experimental design in studying extraction process of Platycodon grandiflorum, which provides basis for feasibility of application of central composite design-response surface method in optimization of extraction process of Chinese traditional medicine.

Objective To investigate the role of variation trend of pre-treatment blood beta human chorionic gonadotropin(β-HCG)in predicting the efficacy of tubal pregnancy(TP)treated by drug therapy.Methods Clinical data of 380 TP patients treated by drug therapy at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2017 to June 2022 were collected.The patients were divided into 271 cases in the pure Chinese medicine(CM)treatment group(shortened as pure CM group)and 109 cases in the combination of Chinese medicine and western medicine group(shortened as combination group)according to the therapy.The relevant factors that may affect the outcomes of the therapy were analyzed,and logistic regression analysis was used for the control of confounding factors.The influences of pre-treatment β-HCG on the outcomes of TP treated by various therapies were investigated,and the value of variation trend of pre-treatment β-HCG in predicting the efficacy of TP treated by drug therapy was assessed using the receiver operating characteristic curve(ROC curve).Results(1)The results of univariate analysis showed that the initial value of blood β-HCG,the variation trend of β-HCG and the difference value of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes in the pure CM group and the combination group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(2)The results of multivariate regression analysis showed that in the pure CM group,the blood β-HCG values and the variation trend of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05 or P＜0.01);in the combination group,the menopausal time and blood β-HCG value detected at the second time before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05).(3)After controlling for the confounding factors,the variation trend of pre-treatment β-HCG in the pure CM group was correlated with the treatment outcomes,and the difference was statistically significant(OR=3.35,95%CI being 1.69-6.65,P = 0.001).However,the variation trend of pre-treatment β-HCG in the combination group did not affect the treatment outcomes,and the difference was not statistically significant(P＞0.05).(4)The ROC curve analysis showed that the area under the curve(AUC)in the pure CM group was 0.74,the cutoff value was-0.14,the sensitivity was 71.3%and the specificity was 67.8%.The AUC in the combination group was 0.67,the cutoff value was 0.10,the sensitivity was 73.6%and the specificity was 60.7%.Conclusion The variation trend of pre-treatment blood β-HCG can effectively predict the efficacy of Chinese medicine for the treatment of TP,but has no value for predicting the efficacy of the combination of Chinese medicine and western medicine in treating TP.The variation value of pre-treatment blood β-HCG can be used as a valuable reference indicator for the early prediction of the outcomes of TP treated by drug therapy.

BACKGROUNDAlthough clinical treatment for heart failure and sudden death has been improved over the last few decades, the morbidity and mortality of dilated cardiomyopathy (DCM) have increased. So a better understanding of the underlying molecular events leading to DCM is urgent. Persistent viral infection (especially coxsackievirus group B3) of the myocardium in viral myocarditis and DCM has never been neglected by experts. Recent data indicate that the up-regulation of coxsackievirus and adenovirus receptor (CAR) in viral cardiomyopathy contributes to viral infection as a key factor in the pathogenesis of this disease. This study aimed to investigate the role and regulatory mechanism of CAR in DCM by the bioinformatic method.

METHODSWe identified the clusters of genes co-expressed with CAR by clustering algorithm based on the public available microarray dataset of DCM (Kittleson, et al. 2005), and mapped these genes into the protein-protein interaction networks to investigate the interaction relationship to each other at the protein level after confirming that the samples are characterized by the cluster of genes in correctly partitioning.

RESULTSThe gene cluster GENESET 11 containing 33 genes including CAR with similar expression pattern was identified by cluster algorithm, of which 19 genes were found to have interaction information of the protein encoded by them in the current human protein interaction database. Especially, 12 genes present as critical nodes (called HUB node) at the protein level are involved in energy metabolism, signal transduction, viral infection, immuno-response, cell apoptosis, cell proliferation, tissue repair, etc.

CONCLUSIONSThe genes in GENESET 11 together with CAR may play a pathogenic role in the development of DCM, mainly involved in the mechanism of energy metabolism, signal transduction, viral infection, immuno-response, cell apoptosis and tissue repair.

Methods The weight of the standard water flow in each flow rate was measured by B2000S digital scales,and the scatter plot between the theory displacement and actual displacement was drawn to find the best fitted curve;then the MATLAB Curve Fitting Tool was used to obtain the best quasi relational equation. Results The error between the fitted displacement and the actual displacement of the gear bump was 1.494% in maximum and-0.010% in minimum, far less than 5% of the requirements for urinary flow meter measurement. Conclusion Based on regression analysis, the relationship between the theoretical displacement and actual displacement of the flow rate meter calibration device is established,the fitting error is small,and the method is simple and easy to achieve.

OBJECTIVETo study the effect and the mechanism of Xuesaitong drop pills (total saponins in Radix Notoginseng; XDP) on experimental thrombosis, thrombolysis and blood theology.

METHODFirst, the rats were randomly divided into five groups: control, XDP (90, 30, 10 mg x kg(-1)), Xuesaitong tablet (XP) 30 mg x kg(-1). Then the effect of the drugs on thrombus and thrombosis was studied after the ratsthrombosis was induced by the arteriovenous shunt. Second, the rats were randomly divided into seven groups: model, XDP (90, 30, 10 mg x kg(-1)), XT (90, 30 mg x kg(-1)), lumbrukinase capsule. Then the effect of the drugs on thrombus and thrombosis was studied after the rats'thrombosis was induced by the electrical stimulation of common carotid artery. Third, the rats were randomly divided into six groups: control, model, XDP (80, 40 mg x kg(-1)), XT (40, 20 mg x kg(-1)). Then the effect of the drugs on blood circulation promoting was observed after the rats'acute blood stasis induced by adrenalin and icy water.

RESULTXDP 90, 30 mg x kg(-1) could notably lighten the wet-weight and dry-weight of thrombus in the arteriovenous shunt model in rats in a dose-dependent manner (P < 0.01). XDP 90 mg x kg(-1) with intragastric administration for 3 days had the satisfactory effect on thrombolysis after the rat's thrombosis was induced by the electrical stimulation of common carotid artery (P < 0.01). XDP 80, 40 , 20 mg x kg(-1) reduced significantly erythrocyte aggregation (P < 0.01) and decreased the whole blood viscosity at low shear rate (P < 0.05). XDP 80, 40 mg x kg(-1) reduced the whole blood viscosity at high shear rate and plasma viscosity (P < 0.05). XDP 80 mg x kg(-1) decreased the whole blood viscosity at high shear rate (P < 0.05).

CONCLUSIONXDP can significantly inhibit the thrombosis and has the satisfactory effect on thrombolysis. One kind of the mechanism is related to the effect on blood rheology.
