Objective:To explore the mechanism of islet cell apoptosis caused by glucose at different concentrations.Methods:The islet cells of SD adult rats were prepared by collagenase digestion,purified by Fcoll400 and cultured in RPMI1640.Different concentrations of glucose or mannitol were added into the monolayer of islet cells.The medium insulin concentration was measured by RIA.The apoptosis rate was measured by the flow cytometry and the bax and bcl-2 expressions were detected by immunoblot.Results:①With glucose concentration raised from 11.1 mmol/L to 22.2 mmol/L,the insulin concentration began to raise and reached the peak,then it began to decline.②With glucose at 11.1 mmol/L and 22.2 mmol/L,the apoptosis rate was the highest,while at 5.5 mmol/L,there was no significant difference compared with the controls. For the groups of mannitol-infused,there was no differences of bax or bcl-2 expressions and no difference of the apoptosis rate comparing with the controls.③With glucose infused,the bcl-2 expressions in 11.1 mmol/L and 22.2 mmol/L groups were negative,bax expression was positive;the bax and bcl-2 expressions were negative in the group of 33.3 mmol/L;the bax and bcl-2 expressions in the 5.5 mmol/L group showed no difference compared with the controls.Conclusion:Higher levels of glucose at 11.1mmol/L and 22.2 mmol/L lead to the release of more insulin and the raise of apoptosis rate.But with glucose concentration at 33.3 mmol/L,the release of insulin decreased and the apoptosis rate declined.Hyperosmolality could not cause the apoptosis of the islet cell.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.
METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).
CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.
