通过物理模型试验和数值模拟计算,对比研究了不同有压出口高度时多级洞塞泄洪洞各项水力特性参数,分析了出口高度对泄洪洞泄流能力、洞身压强及消能率的影响。结果表明,随着出口高度的降低,泄洪洞泄流量减小,流量系数增大;洞身压强整体... 通过物理模型试验和数值模拟计算,对比研究了不同有压出口高度时多级洞塞泄洪洞各项水力特性参数,分析了出口高度对泄洪洞泄流能力、洞身压强及消能率的影响。结果表明,随着出口高度的降低,泄洪洞泄流量减小,流量系数增大;洞身压强整体呈增大趋势,出口压坡高度的变化主要对洞塞及其以后洞段的壁面压强影响较大,而对上平段影响相对较弱;泄洪洞整体消能率逐渐减小,出口高度对竖井洞塞和压坡洞塞消能率影响较大,而对水平洞塞组的消能率影响甚微。 展开更多

Objective:To observe the short-and long-term clinical efficacy differences of body acupuncture and scalp acupuncture combined with extracorporeal shock wave and simple extracorporeal shock wave.Methods:Sixty patients with scapulohumeral periarthritis were randomly divided into two groups:the treatment group and control group,30 cases in each one.Both groups underwent basic rehabilitation training.Patients in the treatment group were treated with body acupuncture and scalp acupuncture combined with extracorporeal shock wave.Yújì(鱼际 LU10),Hégǔ(合谷L14),Zhōngzhǔ(中渚TE3),Hòuxī(后溪SI3).There were three needles for the scalp acupuncture with the first between Shéntíng(神庭 GV24)and Yìntáng(印堂 EX-HN3),and the other two straightly through the inner canthus and parallel to the first needle.Shock wave treatment was intensively applied in some pressure points around shoulder joint.The control group used the same shock wave therapy as the treatment group.Both groups were all treated once a day,6 times a week.Patients were treated for one course which lasted for 4 weeks.VAS score,the Constant-Murley score and the HAMA(the Hamilton Anxiety Scale)are as therapeutic effect index.30 days telephone investigation followed-up after the treatment course was evaluated.Results:Totally 28 cases completed the clinical observation in the treatment group,and 29 cases in the control group.The total effective rate of the treatment group was 85.7%(24/28),which was higher than 69.0%(20/29)of the control group(P<0.05).VAS score:There were significant statistical differences before and after the treatment in the two groups(the treatment group:6.67 ± 1.43 vs 3.47 ± 1.35,the control group:7.57 ± 1.31 vs 5.36 ± 1.45,both P<0.05).There were significant statistical differences before the treatment and at the follow-up in the two groups(the treatment group:6.67 ± 1.43 vs2.68±0.81,the control group:7.57±1.31 vs 4.56±1.35,both P<0.05).The VAS scores of the treatment group after treatment and at the follow-up were respectively lower than those of the control group(both P<0.05).Shoulder joints activity score:There were significant statistical differences before and after the treatment in the two groups(the treatment group:54.65±1.65 vs 65.54±2.19,the control group:54.32 ± 2.31 vs 61.01 ± 0.95,both P<0.05).There were significant statistical differences before treatment and at follow-up in the two groups(the treatment group:54.65 ± 1.65 vs 66.18± 1.35,the control group:54.32 ± 2.31 vs 62.11 ± 1.49,both P<0.05).The shoulder activity scores of the treatment group after treatment and at follow-up were respectively higher than those of the control group(both P<0.05).HAMA scores:There were singificant statistical differences before and after treatment in the two groups(the treatment group:16.83 ± 1.56 vs 13.26 ± 2.36,the control group:17.04 ± 1.84 vs 15.23 ±3.17,both P<0.05).There were significant statistical differences before treatment and at follow-up in the two groups(the treatment group:16.83 ± 1.56 vs 11.01 ± 3.20,the control group:17.04 ± 1.84 vs 13.68 ± 2.49,both P<0.05).The HAMA scores of the treatment group after treatment and at follow-up were lower than those of the control group(both P<0.05).Conclusion:Body acupuncture and scalp acupuncture combined with extracorporeal shock wave can relieve the clinical symptoms of patients with scapulohumeral periarthritis,ease anxiety and improve daily life activities. 展开更多

Objective:To observe clinical efficacy differences of regular acupuncture at empirical acupoints combined with join valley needling at ashi point compared with simple join valley needling at ashi point for scapulohumeral periarthritis.Methods:Sixty-four patients of scapulohumeral periarthritis were randomly divided into an observation group and a control group,32 cases in each one.Both groups underwent basic rehabilitation training.Patients in the observation group were treated with acupuncture at empirical acupoints combined with join valley needling at ashi point,while the patients of the control group were treated with simple join valley needling at ashi point.Both groups were all treated once a day,6 times a week.Patients were treated for one course which lasted for 4 weeks.The visual analog scale(VAS)score,the Constant-Murley score and the Hamilton Anxiety Scale(HAMA)are compared between the two groups before and after the treatment,and the efficacy was evaluated after the treatment.Telephone investigation was applied as the followed-up after one month of the treatment.Results:The total effective rate in the observation group was 87.5%(28/32),and that in the control group was 71.9%(23/32),and there was statistically significant difference between the two groups(P<0.05).The VAS scores,Constant-Murley scores,and HAMA scores in the patients of the observation group were lower than those of the corresponding indicators in the patients of the control group respectively,and there were statistically significant differences(all P<0.05).Conclusions:Compared with simple join valley needling at ashi point,regular acupuncture at empirical acupoints combined with join valley needling at ashi point can relieve the clinical symptoms of patients with scapulohumeral periarthritis,attenuate pains,ease anxiety and improve daily life activities better. 展开更多
