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.

Objective To explore the changes of serum nitric oxide(NO) and trace element Zinc in children with pneumonia and their clinical significance.Methods The observing group contained 48 patients with pneumonia in our hospital from Oct.2005 to May 2006,who were collected 3 mL of blood sample on empty stomach on the second day.Twenty-six of them had been collected serum during their convalescence stage.The control group contained 20 children,who were healthy in the same stage.The levels of NO of 48 pneumonia,26 convalescence stage(recovery group) and 20 healthy patients were determined by UV-2100 spectrophotometer.The Zinc in serum was determined by P-E503-mode atomic absorption spectrophotometric analysis antigenic in those patients.Blood viscosity was measured and analyzed with the statistic analysis SPSS 10.0 software.Results The levels of NO in pneumonia children[(57.76?19.41) ?mol/L] were significantly higher than that in control group [(25.09?5.51) ?mol/L] and recovery group[(30.08?8.05) ?mol/L](P_a

Objective To observe the expression of c-fos mRNA and protein in fluoride treated mouse fibroblast (FB) and osteoblast (OB) and to further explore the effects of c-fos in the osteogenic action of FB. Methods Mouse FB and OB were divided into control group and six fluoride groups (0, 0.0001, 0.0010, 0.1000, 1.0000, 10.0000,20.0000 mg/L F-), and the levels of c-fos protein at 2,4,24,48,72 h and c-fos mRNA at 48 h were measured by using ELISA and RT-PCR methods. Results Compared with the control group, fluoride increased the content of c-fos protein obviously in all FB group(P<0.01); and it is increased in 0.0001,0.0010 mg/L groups at 48 h (0.73±0.04, 0.64±0.14) and 0.0001 mg/L group at 72 h(0.70±0.17) in OB compared with the control group (0.32±0.04,0.27±0.05, P<0.01). Compared with the control group (0.95±0.11), RT-PCR revealed an increasing tendency of the expression of c-fos mRNA at 48 h in FB (1.06±0.16, 1.06±0.12,1.12±0.16,1.04±0.15,1.04±0.10,1.15±0.29), but the difference was not statistically significant(P>0.05); however, a statistically significant difference(P<0.01) of c-fos mRNA in 20.0000 mg/L group(1.40±0.17) in O B was found compared with the control group (1.06±0.06). Conclusion The higher expression of c-fos mRNA and protein in FB induced by fluoride may play an important role in the transformation of osteoblastic phenotype as well as increase the osteogenesis ability in FB.
