Objective To investigate the status of occupational burnout among general practitioners (GPs) and explore the relationship between coping style and burnout. Methods 243 GPs were assessed by Chinese Maslach burnout inventory(CMBI) and simple coping style questionnaire. Results 36.6% of GPs experienced mild burnout, 26.8% moderate burnout, and 3.3% severe burnout; 11.5% of GPs got high scores on emotional exhaustion(EE), 44.9% subjects got high scores on depersonalization(Dp) and 43.6% subjects got high scores on reduced personal accomplishment (RPA). Male GPs experienced greater personal accomplishment than female. Among technical post, subjects with senior technical post scored higher on Dp. The condition of occupational burnout among subjects in north Jiangsu was more serious. GPs with seniority of 5 to 9 years seemed to be more prone to occupational burnout. The coping style of GPs had obvious correlation with occupational burnout. Conclusion The status of occupational burnout among GPs is serious. To prevent and cure occupational burnout, more attention should be paid to female, senior technical post GPs and'persons with seniority of 5 to 9 years. And taking positive coping style can reduce GPs' occupational burnout.

The effect of Fusarin C, a new mutagen extracted from Fusarium moniliforme,on murine peritoneal M? activation by measuring M?-mediated MTC ADCC and CS,Fusarin C could inhibit M? activation by both MAF and FDP. The inhibitory effect was dose-and time-dependent and the curves of dose-and time-response were similar in all three assays. There is, however, apparent difference in Fusarin C dose and time needed to induce significant in hibition among these assays. Significant inhibition occured at 0.4?g/ml and 0.5?g/ml for MTC and CS respectively, but 1.6?g/ml for ADCC. Similarly, the minimal period of time necessary to bring about significant inhibition was 2 hr for MTC, but 3 hr for ADCC. Finally, significance of the inhibitory effect of Fusarin C on M? anti-tumor activity in relation to carcinogenesis was discussed.

The inhibitory effect of Fusarin C,a new mutagen isolated from Fusarium moniliforme,on M? activation was investigated.The inhibitory effect of Fusarin C disappeared partially after 24 hr culture in the absence of the mycotoxin and completely after 72 hr.In addition,it could be overcome by high concentrations of M? activating factor or anti-serum to the target cells.

Objective:To explore the effects of omeprazole combined with somatostatin on intra-abdominal pressure and intestinal mucosal barrier function of elderly patients with severe acute pancreatitis.Methods:Selected 82 cases of elderly patients with severe acute pancreatitis from our hospital.They were divided into research group (48 cases) and control group (34 cases).The control group was treated with basic therapy,and the research group was treated with omeprazole combined with somatostatin on the basis of the control group.Analyzed and compared the clinical effects,intestinal mucosal barrier function and symptom indexes of patients in the two groups.Results:①The total effective rate of the research group was significantly better than that of the control group,and the difference was statistically significant (P=0.005).②After treatment,the D-lactose and diamine oxidase (DAO) levels of both groups were significantly lower than before treatment,and the difference was statistically significant (both P<0.001).In addition,after treatment,the D-lactose and DAO levels were significantly lower in the research group than in the control group,and the differences were statistically significant (mean P < 0.001).③After treatment,patients of the research group showed better results in abdominal pain and abdominal distension relief time,bowel recovery time,hospital stay and blood amylase index than those in the control group,and the difference was statistically significant (mean P < 0.001).④After treatment,the intra-abdominal hypertension of two groups was significantly lower than before treatment,with statistical difference (P < 0.001).Yet it was significantly lower in the research group than in the control group,with statistical difference (P < 0.001).Conclusion:The combined treatment of omeprazole and somatostatin can effectively improve the clinical efficacy of severe acute pancreatitis in elderly patients,correct intra-abdominal hypertension and improve the intestinal mucosal barrier function of patients,so it is worthy of reference and promotion.

AlM: To study the effects of different concentrations of Coix seed oil on human retinal capillary endothelial cells ( HRCECs ) proliferation and vascular endothelial growth factor ( VEGF) expression in high glucose environment.
METHODS: HRCECs extracted from human fresher eyeball and cultured in vitro, and ultimately used in the experiment were the growth of 3rd ~ 4th cells, the experimental were divided into blank control group, low glucose control group, high glucose control group, high glucose + ( 50ü L/mL, 100ü L/mL, 200ü L/mL ) different concentrations Coix seed oil group. Detecting the multiplication of HRCECs by MTT, the immunocytochemical method was employed to detect the each group HRCECs of VEGF expression.
RESULTS:MTT assay results showed that: different concentrations of coix seed oil acted at HRCECs for 48h, inhibition of cell proliferation was significant difference compared with high glucose control group (P<0. 05). Within 48h showed concentration dependence. There was no statistical difference between the low glucose group and high glucose control group (P>0. 05). lmmunocytochemical assay showed that:50ü L/mL, 100ü L/mL, 200ü L/mL Coix seed oil acted at HRCECs 48h, the expression of VEGF decreased significantly compared with the high glucose control group ( P< 0. 05 ), and in a dose- dependent manner. However, in high glucose control group, the expression of VEGF was obvious higher than that of low glucose control group (P<0. 05).
CONCLUSlON:Coix seed oil can inhibit the HRCECs proliferation and suppress the VEGF expression in high glucose environment.

Objective To compare the spatial learning and memory function of heat stroke rats in different periods, to explore the long-term impairment. Methods 42 Sprague-Dawley rats were randomly divided into heat stroke 7 days group (HS7, n=21), heat stroke 21 days group (HS21, n=21), and another 18 rats were performed femoral artery intubation as surgery control group (sham, n=18). They were tested with Morris water maze 7 days and 21 days after modeling respectively for 5 days. The escaping latency, the frequency of crossing the platform area and the duration in the target quadrant were recorded. Results Compared with the sham group, the escaping latency prolonged in HS7 group in all the time (P<0.05), and 4th and 5th days in HS21 group (P<0.05). Compared with HS7 group, the escaping latency short-ened in HS21 group on the 3rd, 4th and 5th days (P<0.05). The duration in the target quadrant shortened in HS7 group compared with the sham group (P<0.05), and prolonged in HS21 group compared with HS7 group (P<0.05). The frequency of crossing the platform decreased both in HS7 group and HS21 group compared with the sham group (P<0.05), and no difference was found between the later 2 groups (P>0.05). Conclusion The impairment of spatial learning and memory is the most seriously 7 days after heat stroke in rats, and it may remain for long time.
