Objective: To observe the curative efficacy of conservative treatment of Qianlie Longbitong tablets on benign prostatic hyperplasia (BPH) and to discuss its influence on blood rheology. Method: Ninety patients were randomly divided into control group (45 cases) and observation group (45 cases) by random number table. Patients in control group received orally 0.2 mg tamsulosin hydrochloride sustained release capsules once every night and 5 mg finasteride tablets once daily. Patients in observation group received orally 4 Qianlie Longbitong tablets thrice daily. Patients in two groups received 12 weeks of treatment. International prostate symptom score (I-PSS)

kidney (gas) deficiency and blood stasis score were evaluated before and after treatment. Size of the prostate

residual urine volume (PVR)

maximum urinary flow rate (Qmax)

average urinary flow rate (Qave) were detected via type-B ultrasonic. The influence of urination on quality of life was evaluated. The blood rheology was tested before and after treatment. Result: Through Ridit analysis

the total efficacy of disease

kidney (gas) deficiency and blood stasis curative effect in observation group were superior to those in control group (P<0.05). After treatment

scores of I-PSS

QOL

kidney (gas) deficiency and blood stasis in observation group were less than those in control group (P<0.01). After treatment

prostate volume in two group was smaller as compared with that before (P<0.01 or P<0.05). PVR of observation group was lower than that of control group (P<0.01). Qmax and Qave of observation group were higher than those of control group (P<0.01). Besides

the improvement of blood rheology indexes as whole blood viscosity (low cut and high cut)

plasma viscosity and whole blood reductive viscosity (low cut and high cut) in observation group were superior to those in control group (P<0.01). Conclusion: Qianlie Longbitong tablets could shrink prostate volume with BPH (kidney deficiency and blood stasis) patients

relieve the symptoms of urinary tract and improve patient quality of life. It has certain effects on the total efficacy of disease and improvement in traditional Chinese medical syndrome.
