OBJECTIVETo observe the effect of Bushen Huoxue Granule (BHG) on dopamine (DA) neurotransmitter and dopamine transporter (DAT) in the brain of patients with Parkinson's disease (PD) as an adjunctive therapy.
METHODSNinety-four PD patients were randomly assigned to two groups, 47 in each group. Madopar was given to all as the basic treatment group. The placebo was given to those in the control group while BHG was given to those in the treatment. The therapeutic course for all was three months. Before and after treatment DA levels in the brain of patients were detected by encephalofluctuograph (EFG) technique. Changes of DAT in the striatum of patients in the treatment group were detected by positron emission tomography (PET) and region of interest (ROI) analysis.
RESULTS(1) Before treatment the DA level was lower in the two groups than the normal value, showing significant difference (P < 0.01), but with no significant difference between the two groups (P > 0.05). After treatment the DA level obviously increased in the two groups, showing significant difference from that before treatment (P < 0.01). No significant difference existed in the DA level in the two groups when compared with the normal value (P > 0.05), but with significant difference between the two groups (P < 0.05). Better results were obtained in the treatment group than in the control group. (2) The DAT radioactive accumulation inside the striatum increased obviously in the treatment group after treatment. ROI analysis showed the total ratio of striatum/cerebellum before and after treatment was 1.86 +/- 0.32 and 2.61 +/- 0.53 respectively, showing statistical difference (P < 0.05).
CONCLUSIONBHG could improve the DA level of PD patients, and increasing DAT contents in the striatum, thus playing a role in effectively treating PD.

OBJECTIVETo study whether acupressure could relieve urinary retention after radical hysterectomy in cervical cancer patients.
METHODSA randomized controlled prospective double-blinded trial was carried out in 107 urinary retention patients undergoing grade III radical hysterectomy. They were assigned to Group A (positive acupoints, 40 cases), Group B (negative acupoints, 32 cases) , and Group C (with no acupoints, 35 cases). All patients received protective 115 000 potassium permanganate sitz bath, 15 - 20 min each time, 3 times per day. Patients in Group A received acupressure at positive points [liniao point and Qihai (RN6)] combined points by syndrome typing [Guanyuan (RN4) , Zhongji (RN3) , Shenshu (BL23) , Zusanli (ST36), Sanyinjiao (SP6), and Taixi (K13)]. Patients in Group B received negative acupressure at sham-acupoints (for adjusting gastrointestinal functions). Patients in Group C only received conventional sitz bath. All medication was performed 3 times per day, 7 days as one therapeutic course, 21 days in total. The residual urine volume was detected. The recovery time for bladder function was recorded. The average residual urine volume was also recorded at day 7, 14, and 21.
RESULTSCompared with Group B and C, the time for ureter retention was shortened for mild and severe CKD patients in Group A (P <0. 01). The residual urine volume was also lessened for mild and severe CKD patients in Group A at day 7, 14, and 21 (P <0.01).
CONCLUSIONCervical cancer patients could relieve urinary retention by self-acupressure after radical hysterectomy.
