Objective To study the protective effect of FGP on liver damage in mice caused by carbon tetrachloride(CCl4).Methods Carbon tetrachloride was used to make the model of chemical liver damage.The mice were randomly divided into 5 groups,10 in each:FGP(10.0 ml/kg)+CCl4,FGP(5.0 ml/kg)+CCl4,FGP(2.5 ml/kg)+CCl4,CCl4(0.12%,10 ml/kg)and the control group.The mice were treated with FGP and CCl4 by gavage and intraperitoneal injection.The biochemical and pathological examinations were conducted to observe the liver damage.Results Compared with CCl4 group,treated with FGP at 5.0 ml/kg could reduce the serum ALT activity significantly,the histopathological findings showed an obvious improvement.Conclusion FGP may have some protective effects on acute live damage caused by CCl4 in the mice.

Objective To study the relationship between long-term high-salt water and the morbidity mechanism of chronic atrophic gastritis (CAG), The expression of HSP60 and ras protein were detected in the gastric mucosa of CAG rates induced by high-salt water.Methods The atrophic gastritis rat model was made by high-salt-hot water perfusion and the ultrastructure of gastric mucosa was observed by Laser Scanning ConfocaI Microscopy. Results There was no expression in gastric mucosa in normal group. The expression of HSP60 and ras was observed in the cell plasm of rats at 12 weeks. The higher expression was observed in the rats at 24, 32 and 65 weeks. Using laser scanning confocaI microscopy and immunofluorescence technique had observed coexistence of HSP60 and ras.Conclusion Long time high-salt-hot water can induce CAG and increasing the expression of HSP60 and ras. HSP60 and ras play an important role in the formation of atrophic gastritis.

Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0% (21/21) and 95.2% (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0%(23/23),0 and 45.1%(23/51).The corresponding values for MR were 91.3%(21/23),82.1% (23/28) and 86.3% (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P<0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0%(42/42),42.9%(21/49) and 69.2%(63/91),respectively.The corresponding values for MRI were 95.2 %(40/42),87.8%(43/49) and 91.2%(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P<0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P<0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

Objective To explore the preventive effect of early bowel intervention on the gastrointestinal dysfunction in patients with invasive mechanical ventilation.Methods Sixty patients with invasive mechanical ventilation were equally randomly divided into the observation group and the control group.patlents in the control group were treated by conventional nursing care,while Patients in the observation group were given the early bowel intervention including abdominal massage and stimulation of rectum.The two groups were compared in terms of gastrointestinal dysfunction.Result The rate of gastrointestinal dysfunction in the observation group was significantly lower than that of the control group(P<0.05).Conclusion The early bowel intervention may effectively promote intestinal peristalsis,protect the intestinal digestion, absorption of nutrients and mucosal barrier function and prevent gastrointestinal dysfunction in patients with invasive mechanical ventilation during enteral nutrition.

Objective To explore related factors of amputation in patients with diabetes foot ulcer(DFU) and provide the evidence of reducing amputation rate.Methods A total of 307 inpatients with DFU in this hospital from October 2013 to December 2015 were collected and divided into amputation group(n=28) and non-amputation group(n=279).The clinical data and laboratory data were treated with single variable analysis and multivariate Logistic regression analysis.Results Single variable analysis showed that hospitalization time,hyper-sensitive C-reactive(hs-CRP) and fibrinogen(FIB) level were significantly increased in amputation group(P<0.05) when compared with non-amputation group,and the hemoglobin (Hb) level,high-density lipoprotein cholesterol(HDL) and serum albumin (ALB) level in amputation group were markedly lower than in non-amputation group(P<0.05).Amputation rate was significantly different among different Wagner grades (P=0.000).Multivariate Logistic regression analysis showed that hospitalization time,Wagner grade were independent risk factors of amputation in patients with DFU,OR values were 1.024(95%CI:1.009-1.039) and 2.779 (95%CI:1.753-4.404),respectively.While HDL was a protective factor of amputation in patient with DFU (OR=0.161;95%CI:0.036-0.729).Conclusion The higher the rank of Wanger in DFU patients are,the longer hospital stay and the higher amputation risk become.HDL is the protective factor of DFU amputation.

Objective: To investigate the effects of tea polysaccharide (TP) on blood glucose and diabetic symptoms in mice. Methods: Alloxan-induced diabetic mice were divided into 4 groups, and administered orally with saline, TP at doses of 1.0, 2.0, 4.0 g/kg body weight, respectively for 4 weeks. Water intake and body weight were recorded daily and weekly respectively.Fasting blood samples were collected for measurement of glucose at the end of 2nd and 4th week.Results: Symptoms of diabetic mice fed TP were improved obviously. Their blood glucose concentration and water intake decreased significantly. On the other hand, their body weight increased obviously. There was positive correlation between blood glucose and water intake, but negative correlation between water intake and body weight. Conclusion: TP can decrease blood glucose concentration and improve diabetic symptoms in mice.
