Objective To explore the mammographic characteristics and technique in mammary tumor.Methods The mammographic materials of 200 cases with breast tumors which were confirmed by surgery, ultrasonography, biopsy or clinic follow-up were collected and analyzed retrospectively.Results Benign mammary tumors were found in 138 cases. They were the masses with round or ellipse in shape mammographically and soft clinically. In 62 cases of breast cancer, the mammogram showed irregular masses in 37 cases (59.7%), oval in 25 (40.3%), clustered tiny calcification in 32 (51.6%) and local infiltration in 4 (6.5%). The masses were hard on palpation, and their sizes were smaller on mammogram than that on palpation. Conclusion mammography is the initial modality for breast tumor, which can demonstrate main direct and indirect signs of the breast cancer, and shares high value in early diagnosis and differential diagnosis of the disease.

Objective To investigate operation time on biliary duct stone with acute gallstone pancreatitis.Methods The clinical data of 44 patients with acute gallstone pancreatitis who were admitted to Department of General Surgery,Taicang First People's Hospital for surgical management from January 2011 to December 2013 were retrospectively analyzed.Patients were divided into early surgery group and delayed surgery group according to the timing.Early surgery group was defined as the patients whose symptoms of pancreatitis were basically disappeared after conservative treatment and surgery was performed within two weeks,while delayed surgery group was defined as the patients who underwent surgery after two weeks.Results Of the 44 acute gallstone pancreatitis cases,18 patients were males,and 26 were females,with median age of 54 years old (range 26-83 years old).Forty-two cases were mild acute pancreatitis and the other two cases were severe acute pancreatitis.Preoperative imaging indicated both cholecystolithiasis and choledocholithiasis in 5 patients,cholecystolithiasis alone in 39 patients.The 5 patients underwent cholecystectomy and choledocholithotomy with T-tube drainage.Among these 5 cases,one patient with concomitant acute suppurative cholangitis had an emergency surgery,two patients with Ranson score ≤3 had early surgery,and two patients with Ranson score ≥4 had delayed surgery,and all the patients were cured and discharged.Thirty-nine cases with cholecystolithiasis alone were treated with laparoscopic cholecystectomy.Among the 39 patients,25 patients underwent early laparoscopic cholecystectomy,and the other 14 patients underwent delayed surgery,and all the patients were cured and discharged.When compared with delayed group,the average age and Ranson score of early group were lower [(46 ± 12) yrs vs (64 ± 11) yrs and (1.0 ± 0.5) vs (1.5 ± 0.8)],and the median hospital length of stay and the cost were significantly less in the early group than those in the delayed group [(14.0 ± 2.8) d vs (18.1 ± 3.3) d and (17 899 ± 3461) Yuan vs (23 710 ± 3230) Yuan],and the difference between the two groups was statistically significant (P＜0.05).Nevertheless,there was no difference between the operation time and recovery time.There was no conversion to open surgery or post-operative complication in the two groups.Conclusions For severe acute pancreatitis,the delayed operation is recommended when the symptom of pancreatitis is completely improved after conservative management,while for mild acute pancreatitis,early surgery does not increase operation difficulty and complication,and it can decrease the length of hospital stays and costs.

OBJECTIVE: This research focuses on the psychologic status of children patients with congenital malformation of external and middle ear by Achenbach's Child Behavior Checklist (CBCL) in order to explore the degree of the influence. METHOD: The 66 patients of 4-16 years old were assessed psychologic status with CBCL filled in by their parents according to their performance in half a year. Then calculated the detection rate of behav ioral disorders of these patients. Collected all patients' general information and Marx's grade of malformed ears. Then analyzed the relationship between the detection rate and these factors. RESULT: The detection rate of behavioral disorders of 4-16 years old patients, 21.21%, which is higher than that of Chinese norm. The Marx's grade and parents' mental stress relate with the behavioral disorders. In Logistic regression analysis, the value of Cox & Snell coefficient of the regression model is 0. 153. The detection rate of behavioral disorders in grade III patients (36.4%) is greater than that of grade II (4.3%), P = 0.004. CONCLUSION Congenital malformation of external and middle ear has an absolute influence on the patients' psychologic status, but its effect is only about 15% parts of the multitudinous influential factors. And grade III patients carry a high-risk for behavioral disorders.
