ABSTRACT
Objective To observe the clinical therapeutic effect of Capsule Long-Bi-Xiao(LBX) in treating benign prostatic hyperplasia(BPH).Methods 64 patients of deficiency of Qi and blood stasis type suffered with BPH were randomly divided into two groups.30 patients in the control group were treated with Capsule Long-Bi-Shu,while other 34 patients in the treated group were treated with LBX.Each group was observed for there months respectively.Results LBX decreased the international index of prostatic symptom(I-Pss) and the bother score(BS),improved the prostatic symptoms,raised the peak flow rate(Qmax) and the average flow rate(Qave),shrinked a portion of patients′ volume of prostate gland,reduced the volume of residual urine.After treatment,in the treated group,I-PSS and BS were reduced distinctly,and Qmax and Qave were heightened obviously,which was more effective than those in the control group.Conclusion LBX can achieve good action in the therapy of BPH by improving clinical symptoms,diminishing the volume of prostate and ameliorating the difficulty of urination.
ABSTRACT
Objective: To better understand the antagonistic effect of Xiao Long Tong Bi (XLTB), a Chinese herb medicine, on α1-adrenoceptor (α1-AR). Methods: (1) Radio ligand binding assay . Specific 125I-BE2254(2-β(4-hdroxyphenyl)-ethyl amino-methyl-tetralone) binding was measured by incubating membrane of canine cerebral cortex with a single concentration of 125I-BE2254 in the presence of 15 concentrations of XLTB. Half-effectual concentration of inhibition (IC50) and Hill coefficients (nH) were determined by Hill plots. (2) Contractile responses of rat prostate strip in vitro were determined. pKB values for XLTB in competitively inhibiting NE-stimulated contraction of tissues were measured by the method of Ainlakshana. Results: XLTB competitively inhibited binding of 125I-BE2254 to α1-AR in a concentration -dependent manner. IC50 values for XLTB in canine cerebral cortex were (34.0±6.0) g*L－1, the Hill efficiency value (0.7±0.1) was significantly decreased from unity. Contractile studies showed that XLTB competitively antagonized the NE concentration-response curve with pKB values of (37.0±11.0) g*L－1 or (30.0±8.0) g*L－1 when XLTB concentration was 70 g*L－1 or 170 g*L－1, respectively. The pKB values for XLTB in antagonizing NE-induced contraction of tissues were showed to fit in well with the IC50 values on rat prostate. Conclusion: These results suggest that XLTB appears to be a competitive antagonist for α1-AR.
ABSTRACT
Objective: To make further evaluation on the efficacy and safety of Chuan Shen Tong Injection (CSTI) on benign prostatic hyperplasia with blood-stasis syndrome. Methods: A self-contrast between pre-and post-treatment and multicenter trial was carried out in 2090 subjects treated with CSTI over 4 weeks. Results: The markedly effective rate of CSTI in controlling symptoms is 60.77 %and the total effective rate is up to 91.67 %. Conclusion: Chuan Shen Tong Injection is effective and safe in treating benign prostatic hyperplasia with blood-stasis syndrome.
ABSTRACT
Objective To evaluate the curative effect and safety of Niaoshit on g pill in the treatment of urinary calculus.Method Multi- center randomized co ntrolled clinical trial was adopted. Three hundred and twenty cases were accepte d to the study, in which 200 cases were treated by Niaoshitong pill and 120 case s by Shilintong tablet as control. The effect of both groups was observed. Resul t 107 cases (53.5 % ) were cured, 53 cases(26.5 % ) effective, the total effe ctive rate being 80.0 % in the treatment group, and 27 cases(24.5 % ), 42 cas es (38.2 % ), and 62.7 % respectively in the control group. In a open group of 120 cases ,54 cases (45.0 % ) were cured, 44 cases (36.6 % ) were effective , the total effective rate being 81,6 % .Conclusion Niaoshitong pill can mark edly improve the clinical symptoms and exerts a strong lithagogue effect. It can promote the elimination of calculi after external blast lithotrity or ureterosc opic lithotrity, prevent the formation of 'stone street', and reduce the strictu re formed by the damage of ureter.
