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 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.

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 investigate the effects of apoptosis and related gene p21WAF1 and Bcl-2 in the tumorigenesis of primary gallbladder neoplasms. Methods p21WAF1 and Bcl-2 were detected by immunohistochemistry and apoptotic cells were stained in situ by terminal deoxynucleotidyl transferase mediated-dUTP nick end labeling(TUNAL) in 46 cases of primary gallbladder neoplasms with different histological grades. Results Apoptotic index and p21WAF1 were decreased,but the expression of Bcl-2 was increased with the increasing of the histological grades in primary gallbladder neoplasms (P

Objective To investigate the effect of chronic intermittent hypoxia (CIH) on myocardial tissue pathology,oxidative stress and apoptosis in rat fed a high-fat diet,and to explore the possible mechanism of CIH induced cardiomyocyte injury.Methods A total of 24 male Wistar rats were randomly divided into 3 groups (n=8 each).The control group was fed common rat forage,the high-fat group was fed high-fat forage,and the high-fat plus intermittent hypoxia group was fed high-fat forage combined with a 7h/d intermittent hypoxia treatment.The changes of myocardial tissue pathology and ultrastructure of cardiomyocyte,and the activities of apoptosis regulating factor cysteine-containing aspartate-specific proteases-3 (caspase-3) and oxidative stress marker myeloperoxidase (MPO) were observed in the 3 groups after 4 weeks of treatment.Results There were significant differences in the activities of caspase-3 and MPO among the three group (F=89.94,71.24,both P＝0.001).The activities of caspase-3 and MPO were lower in the control group than in the high-fat group and in high fat plus intermittent hypoxia group [(0.21±0.06) vs.(0.80±0.11),(1.15±0.21),(3.20±0.58) vs.(10.87±1.96),(13.17±2.22),P＜0.01].The activities of caspase-3 and MPO were higher in the high-fat plus intermittent hypoxia group than in the high fat group[(1.15±0.21) vs.(0.80±0.11),(13.17±2.22) vs.(10.87±1.96),P＜0.01].No abnormal findings in the structure of cardiomyocyte were observed in the control group,while multiple pathologic damages in cardiomyocyte were detected in the high-fat group,and more obvious injuries in the high-fat plus intermittent hypoxia group.Conclusions The pathologic damages to cardiomyocyte are more serious in high fat and intermittent hypoxia group than in the high-fat group.Apoptosis induced by oxidative stress may play an important role in the pathogenesis of these injuries.
