A Research Of Point Speciality Using Electroacupuncture At Zhongliao Points For Benign Prostatic Hyperplasia

[Object] To observe and discuss the specificities of acupoint of electroacupuncture at Zhongliao Points for Benign Prostatic Hyperplasia.[Medthods] 52 patients of BPH were randomly divided into two groups, experimental group(acupuncture group) is 27 in electronic acupuncture on zhongliao(BL33), control group(non-acupoints group) is 25 in electronic acupuncture on acupuncture point at 2 inches side opening. Observing the change of International Prostatic Symptom Score(I-PSS),QOL,Postvoid residual urine and Qmax after 4 weeks' trerapy. We also observe the tolerance,security and compliance during the needling process.[Result] Main outcome index:I-PSS. Acupuncture group:Before therapy: 20.8000±7.16473, after therapy:13.0400±6.35400, compared with the changes before and after treatments, I-PSS of acupuncture group is statistically significant difference (P<0.01); Non-acupoints group:Before therapy:18.7500±5.41536, after therapy:19.0000±5.37304, the data is statistically not changed remarkably (P>0.05). Differential analysis is statistically significant difference (P<0.01); Comparison among groups, There is no significant difference between two groups before treatments, it shows better comparability, and after 4 weeks'therapy, there is statistically significant difference (P<0.01).Secondary outcome index:①QOL:Acupuncture group:Before therapy: 4.9600±1.27410, after therapy:2.1600±1.21381; Non-acupoints group:Before therapy:4.9583±0.75060, after therapy:4.2917±0.80645, Compared with the changes before and after treatments, QOL of acupuncture group and non-acupoints group is statistically significant difference (P<0.01); Differential analysis is statistically significant difference (P<0.01); Comparison among groups, There is no significant difference between two groups before treatments, it shows better comparability, and after 4 weeks' therapy, there is statistically significant difference (P<0.01).②Postvoid residual urine,③Qmax:Postvoid residual urine: Acupuncture group:Before therapy:18.7200±7.92948, after therapy: 18.3600±3.74032; Non-acupoints group:Before therapy:18.3375±5.25637, after therapy:20.2917±4.77748; Qmax:Acupuncture group:Before therapy: 14.4227±8.65585, after therapy:13.6923±7.26467; Non-acupoints group:Before therapy:13.9955±5.91628, after therapy:13.1409±5.60329. Compared with the changes before and after treatments, postvoid residual urine and Qmax of acupuncture group and non-acupoints group is statistically significant difference (P>0.05); Differential analysis is no statistically significant difference (P>0.05); Comparison among groups, There is no significant difference between two groups before and after treatments (P>0.05), comparability worse. The results of data needed to be further collection and research.According to the course of treatment, there are 49 cases came into results among the 52 patients, and 5 cases do not have the data of Qmax because of machine fault (3 cases in the acupuncture group and 2 cases in the non-acupoints group), the compliance is good. No complications occurred except subcutaneous hematoma in 2 patients and both of whose hematomas disappeared after 2-3 days, so the treatment has well security to patients.[Conclusion] Electronic acupuncture on zhongliao(BL33) can improve the patients'I-PSS and QOL significantly, the curative effect is obviously better than non-acupoints group; The index of postvoid residual urine and Qmax needed to be further observed. The trial preliminarily demonstrated the acupuncture at Zhongliao Points have the specific effect of for Benign Prostatic Hyperplasia.
