Clinical Study on Kangquan Recipe (康泉方) for Benign Prostatic Hyperplasia Patients:A Randomized Controlled Trial

Objective：To observe the effectiveness and safety of Kangquan Recipe（康泉方,KQR） for benign prostatic hyperplasia（BPH） patients.Methods：One hundred and six BPH patients were randomly assigned to the treatment group（53 cases） and the control group（53 cases） according to a random number table.The treatment group was given KQR orally;the control group was given cemilton orally.After 24-week treatment,the clinical effect and safety were evaluated using the International Prostatic Symptom Score（l-PSS）,quality of life（QOL）,maximum flow rate（Qmax）,average flow rate（Qave）,residual urine volume（RUV）,total prostatic volume（TPV）,etc.Results：After treatment,the score of l-PSS was decreased from 16.9 ±5.6 to 12.5 ±4.6in the treatment group,significantly lower compared with the control group;the levels of Qmax and Qave were from 10.9 ±3.5 to 15.6 ±4.5 and 5.4 ±2.1 to 7.3 ±2.5（mL/s） in the treatment group,significantly higher compared with the control group;the levels of RUV and TPV were from 70.8 ±28.2 to 35.2 ±21.8 and37.2 ± 16.9 to 30.1 ± 10.8（mL） in the treatment group,significantly lower compared with the control group（all P〈0.05）.The incidence rate of adverse reaction was similar between the two groups（P〉0.05）.Conclusion：KQR is effective and safe for the treatment of BPH.

Inhibition of Yuyihe Powder on Tumor Growth in Mice Models of Sarcoma 180

Objective To explore the antitumor effect of Yuyihe Powder（Yu Yi He San,YYHS） and its antitumor mechanism.Methods After treatment,tumor weight,immune apparatus weight,the life span of transplanted animals,spleen lymphocyte proliferation assays,and IL-2 concentration in mouse serum were recorded or detected.Results YYHS showed strong antitumor ability.Compared with control group,mid-dose YYHS（1.0g/kg） could inhibit the tumor growth,prolong the life span of S180-bearing mice to some extent,significantly increase the thymic and splenic indices of S180 mice,and strongly promote the secretion of IL-2 in blood;The inhibitory rate on tumor growth and life prolongation rate were 37.1%and 38.37%,respectively.Conclusion YYHS could not only significantly inhibit the growth of S180 cells,but also markedly prolong the survival time of S180 bearing mice.The mechanism of antitumor effect could obviously enhance immunologic function of the S180 bearing mice to inhibit the growth of S180 cells.
