Aim To observe the changes of endothelin receptors and their subtypes of left ventricules in normal SD rats and dilated cardiomyopathy rats. Methods To establish the best conditions of the binding experiment, different protein concentrations, incubation temperature ?and?incubating?time?were?tested? with 125 I-ET-1 ligand respectively. With the selected conditions, saturation binding experiments were performed to determine the amount of endothelin receptor and its subtypes in normal SD rats and in dilated cardiomyopathy ones. Results (1) The optimal incubating temperature was 37 ℃. Under this condition, the binding amount of 125 I-ET-1 increased rapidly in 0~30 minutes, and reached to saturation point at 60 minutes, and there was a linear correlation between 125 I-ET-1 binding amount and cell membrane protein concentration. (2) Endothelin-1, bosentan,BQ123,BQ788 etc. could competitively suppress the bound of 125 I-ET-1 to endothelin receptors. (3) The amount of endothelin receptor in left ventricle of dilated cardiomyopathy rats was ( 92.21? 34.34) nmol?kg -1 protein, which was significantly low than that in normal SD ones. There was no change on the ratio of endothelin receptor subtypes A and B. Conclusion 125I-ET-1 can be used to determine the amount of endothelin receptor and its subtypes in varied tissues specifically. The amount of endothelin receptor in left ventricle of dilated cardiomyopathy rats is down regulated, but the ratio of endothelin receptor subtype A vs B remains to be 21.

OBJECTIVETo verify the clinical effect of the penetration acupuncture at the acupoints of governor vessel(GV) and bladder meridian on head for mild cognitive disorder after stroke.
METHODSOne hundred and ten patients were randomly divided into an observation group and a control group, 55 cases in each one. Penetration acupuncture was used at the acupoints of GV and bladder meridian on head in the observation group,namely Wuchu (BL 5) to Chengguang (BL 6) and Tongtian (BL 7) to Luoque (BL 8) bilaterally, and Shenting (GV 24) to Xinhui (GV 22), Qianding (GV 21) to Baihui (GV 20), Houding (GV 19) to Qiangjian (GV 18). Body acupuncture and conventional western medication were applied in the both two groups. Acupuncture was adopted once a day, five times a week and eight weeks totally. The changes of Montreal Cognitive Assessment (MoCA), Mini mental state examination scale(MMSE), self-rating depressive scale (SDS) and activities of daily living scale (Barthel index) were compared between the two groups before treatment, in the middle of treatment(at the forth week) after treatment(at the eighth week) and in three weeks after treatment(follow-up).
RESULTSAfter treatment of four and eight weeks and at the time of follow-up, the results of MoCA, MMSE, SDS and Barthel index were apparently im proved compared with those before treatment in the two groups (all P < 0.01). After treatment of eight weeks and at the time of follow-up, the scores of MoCA and SDS were obviously improved in the observation group compared with those in the control group (P < 0.01, P < 0.05). The improvements of MMSE in the observation group were more marked than those in the control group at all times (P < 0.01, P < 0.05). But there was no statistical significance about the change of Barthel index between the two groups (all P > 0.05).
CONCLUSIONPenetration acupuncture at the acupoints of GV and bladder meridian on head can remarkablely improve the cognitive function of the patients with mild cognitive disorder after stroke,and have some efficacy of relieving the bad mood such as depression.
