0.05).The levels of serum TC in groups A,B,and C were (23.51?10.58),(14.27?3.51)and(1.36?0.33)mmol?L-1, respectively; the levels of serum LDL in groups A,B,and C were (21.39?10.00),(14.23?4.01)and(0.72?0.35)mmol?L-1;there were significant differences between three groups (P0.05).Conclusion High-fat diet has no significant effect on the expressions of NO and PAI-1 in atherosclerosis rabbits .Atorvastatin can increase the expression of NO and decrease the expression of PAI-1,and can inhibit the progression of atherosclerosis.

Objective To set up an objective criterion for BI-RADS assessment.Methods The breast sonograms of 1 938 female cases were retrospectively studied which had been confirmed by pathology from January to September 2011 and 2012 January.1 660 cases during 2011 were model cases,and the importance of each single feature in distinguishing between benign and malignant was obtained with Chi square and OR value.A detailed criterion of BI-RADS assessment category was set up based on US-BI-RADS.Results Eighteen of 24 lexicons were statistically significant distinguished between benign and malignant breast masses(P ＜ 0.05).The lexicons were divided into major suspicious signs,middle ones and minor ones assigned 3 points,2 points and 1 point,and a scoring model was established as follows:Score =3 * (X1 + X2 + … + X6) + 2 * (X7 + X8 + … + X12) + (X9 + X10 + … + X18).Based on BI-RADS,the positive predictive value of model cases was 1.5％,6.9％,22.1％,62.5％,96.1％ followed by category 3,4A,4B,4C and 5,and it was 1.4％,3.4％,21.1％,69.4％,92.7％ in test cases.Conclusions The scoring model could be useful for BI-RADS final assessment more objectively,and could make it more convenient to predict the risk of breast cancer.

Objective To evaluate the effect of early non-liquid diet for patients with mild acute pancreatitis by using Meta-analysis. Methods The randomized controlled trials(RCT) on early non-liquid diet intake for patients with mild acute pancreatitis were collected by computer searching the database of China National Knowledge Infrastructure(CNKI),Wanfang Periodical Database,CBM,Elsevier Scien Direct, cochrane library and PubMed from inception to February 2017, and analyzed by RevMan 5.2 software. Results Five RCTs were included in the study.The Results of Meta-analysis revealed that both the length of hospitalization after eating [MD=-1.48,95%CI-2.50~-0.47, P=0.004] and the total length of hospitalization[MD=-1.99,95%CI-(0.99-2.99),P=0.0001]in liquid diet group were less than that of non-liquid diet group,and the differences were statistically significant.There was no significant difference in the rate of the pain recurrence[RR=1.21,95%CI 0.77-1.91,P=0.40]and the rate of the elimination of oral feeding[RR=1.02,95%CI 0.45-2.30,P=0.96]because of pain,nausea or vomiting after refeeding,although all that rate in non-liquid diet was not lower than that of liquid diet group. Conclusions compared with liquid diet,early non-liquid diet intake for mild acute pancreatitis can shorten their hospitalization time, and it cannot be concluded that the non-liquid diet will increase the pain recurrence rate, and most patients have a better tolerance to non-liquid diet,and non-liquid diet can promote rehabilitation.
