Objective To analyze recent 30 years’ regularities in point selection for acupuncture treatment of Parkinson disease and provide reference for its treatment. Methods Parkinson disease, parkinsonism and acupuncture were used as key words. Recent 30 years’ Chinese literature was searched using Wanfang, CNKI, VIP and Chinese biomedical literature database. Selection of main acupoints and scalp acupuncture points, syndrome differentiation-based point selection and meridian tropism of main acupoints were metrologically studied. Results The Du meridian, the large intestine meridian and the gallbladder meridian were mainly selected for acupuncture treatment of Parkinson disease. Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) were used as main points. Chorea-tremor control area, motor area and parietotemporal anterior oblique line were often selected as main scalp acupuncture points. Fenglong (ST40), Qihai(CV6), Sanyinjiao(SP6), Yinlingquan(SP9) and Zusanli(ST36) were often used according to syndrome differentiation-based point selection. Conclusion Modern acupuncture doctors select Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) as main points, often use scalp acupuncture points and combine points mainly from the Du meridian according to syndrome differentiation in the treatment of Parkinson disease.

BACKGROUND: There are many methods for posterior cruciate ligament (PCL) reconstruction, which is involved in many graft materials, but few studies aim to compare the differences in outcomes of different grafts for PCL reconstruction. OBJECTIVE: To compare the clinical results of arthroscopic PLC reconstruction with bone-patellar tendon-bone (B-PT-B) autograft, B-TP-B allograft and semitendinosus tendon autograft. DESIGN, TIME AND SETTING: A retrospective case analysis was completed in the Department of Orthopedics, Guangzhou General Hospital of Guangzhou Area Military Command of Chinese PLA from January 2000 to September 2005. MATERIALS: Totally 76 patients underwent arthroscopic PLC reconstruction from January 2000 to September 2005, with the use of B-TP-B autograft in 21 patients, B-TP-B allograft in 27 patients, semitendinosus tendon autograft in 28 patients. METHODS: A retrospective analysis was performed in 76 patients underwent arthroscopic PCL reconstruction, with the use of B-TP-B autograft in 21 patients, B-TP-B allograft in 27 patients, semitendinosus tendon autograft in 28 patients. Postoperative body temperature was examined duration hospitalization. The follow-up parameters included International Knee Documentation Committee (IKDC) scores, Lysholm knee joint scores, and KT-1000 evaluation.MAIN OUTCOME MEASURES: ①Range of motion. ②joint stability: posterior draw test and KT-1000 test. ③overall function of knee: IKDC scores and Lysholm scores; ④complications and side effect. RESULTS: The time of follow-up visit was 26-79 months. Differences were no statistically significant among the IKDC scores, Lysholm scores, KT-1000 side-side difference, the positive rate of posterior draw test in three groups of patients with PCL reconstruction using B-TP-B autograft, B-TP-B allograft and semitendinosus tendon graft (P > 0.05); 10° flexion limitation was found in 3 cases of B-TP-B autograft, 5° flexion limitation in 1 case of B-TP-B allograft and flexion limitation in 2 case of semitendinosus tendon graft. There was no significant difference in the ratio of knee joint flexion limitation among three groups. No synarthrophysis, wound infection, implant disrupture, screw loose, patellar fracture or vascular nerve injury was observed in three groups of patients; There were 12 cases presenting anterior knee pain in the B-TP-B autograft group and 5 cases presenting posterior knee pain in the semitendinosus tendon graft group. The difference of peal-knee pain incidence was statistically significant among three groups (P=0), the highest in B-TP-B autograft group, then semitendinosus tendon graft group and the lowest in B-TP-B allograft group. The time of post-operative fever in B-TP-B autograft group was earlier than that in the B-TP-B allograft and semitendinosus tendon graft groups (P=0). There was no significant difference between allogreft group and semitendinosus tendon autograft group (P=0.844). The rejections appeared in 4 cases of B-TP-B allograft with the manifestations of the sustained jam-like liquid outflow from tibial tunnel. After dressing, hormones or indomethacln, the rejection was healed. CONCLUSION: The arthroscopic B-TP-B autograft, B-TP-B autograft and semitendinosus tendon autograft have the same clinical curative effect in PCL reconstruction.
