Objective To compare the different operation routes of laparoscopic right hemicolectomy (up‐to‐down vs.medial‐to‐lateral dissection sequences ).Methods In total ,56 cases enrolled in the Central Hospital of Wuhan between Janu‐ary 2013 and January 2014 were randomly divided into the up‐to‐down group and medial‐to‐lateral group.Statistical data in terms of general information ,operation time ,blood loss ,rate of conversion to open surgery ,number of lymph nodes harvested , postoperative complications ,time to first bowel movement and hospital stay time were compared and analyzed.Results The up‐to‐down group has the advantages of shorter operation time [(128.24 ± 21.14) min vs.(166.45 ± 30.23) min ,P<0.01] ,lower conversion rate(0% vs.7.14% ,P=0.035)and less blood loss= [(45.67 ± 10.66) mL vs.(78.45 ± 40.28) mL ,P<0.01] than the medial‐to‐lateral group.However ,there were no significant differences in terms of general information ,number of lymph nodes harvested ,rate of postoperative complications ,time to first bowel movement and hospital stay time (all P>0.05) .Conclu‐sion Taking the superiority of broad perspective ,clear image ,safety and less blood loss into consideration ,the up‐to‐down op‐eration route of laparoscopic right hemicolectomy deserves clinical recommendation.

Objective:To evaluate the utilization of antifungal drugs in Nanjing area, and provide clinical reference for the rational use of antifungal drugs. Methods:According to the sales data of antifungal drugs in 34 hospitals in Nanjing area from 2013 to 2015, the utilization of antifungal drugs was analyzed in respects of consumption sum, DDDs and DDC. Results:The consumption sum and use of antifungal drugs increased year by year. The maximum amount of consumption sum growth rate was 41. 13%. Triazole drugs oc-cupied the top of consumption sum during the past three years, and the sales amount accounted for more than 60% of all. In term of consumption sum, voriconazole, fluconazole, itraconazole and caspofungin ranked top 4 of antifungal drugs. Clotrimazole topical prepa-rations and oral itraconazole ranked top 2 of DDDs, and caspofungin, micafungin and voriconazole ranked top 3 of DDC. Conclusion:The clinical application of antifungal drugs continues to increase during 2013 and 2015. Invasive fungal infection is a lethal factor at high risk. Choosing reasonable, effective, safe and economic of antifungal drugs is the first principle in clinical treatment.

Objective To explore the the effect of Omeprazole combined with operation on treatment of rupture of small intestine in closed abdominal injury.Methods From June 2014 to December 2014,64 cases in Xinchang county people's hospitalwith rupture of small intestine in closed abdominal were divided into the treatment group and the control group,32 cases in each group.The control group were treat with surgery,the treatment group were given surgery combined with Omeprazole.The total effective rate,quality of life,the recovery time of bowel sound and the echaust time in the two groups were compared.Results The total effective rate(90.6％,29/32)in the treatment group was significantly higher than that in thecontrol group(75.0％,24/32),the difference is significant(P< 0.05).The life index in the treatment group is significantly better than that in the control group(P<0.05).The recovery time of bowel sound in the treatment group(15.3±2.6)h,is shorter than that in the control group(23.8±6.8)h; the exhaust time(23.6±2.2)h in the treatment group is lower than that in the control group(32.3±4.6)h,the differencesis statistically significant(P< 0.05).Conclusion It can significantly improve the effect and postoperative indexes which omeprazole combined with surgical treatment on the treatment of rupture of small intestine in closed abdominal injury,Itshould be widely promoted.

Objective To emphasize the importance of establishing the efficient scientific archives management of measuring appliance for the hospitals' modern construction in the present situation.Methods Integrated archives of measuring appliances were established and the organization of hospital-metrology-management archives was completed.Results The effect of measuring appliance archives management was exerted adequately.A reliable safeguard was offered to promote the quality of medical treatment and decrease the medical litigation.Conclusion The establishment of effective scientific archives management of measuring appliance has an important influence in promoting the quality of medical treatment and enhancing the safety.

Objective To investigate the prevalence rate of thyroid nodules as well as related influencing factors. Methods In this clinical study, 8,912 healthy people were included, involving medical staff, teachers, electric enterprise staff and civil authorities from January to December in 2014 . The prevalence rate of thyroid nodules and related influencing factors were investigated . Results (1) The prevalence rate of thyroid nodules was 40.4%, 34.9%for male and 46.7%for female. The prevalence of female was higher than that of male (P<0.001);(2) The prevalence rate of thyroid nodules showed a trend of increase with age (P<0.01);(3) The prevalence rate of thyroid nodules in medical staff and teachers was significantly higher than others (P<0.001);(4) The difference was statistically significant in BMI, blood pressure, blood lipid, blood glucose in thyroid nodule group and non thyroid nodules group (P<0.001). All indexes mentioned above of thyroid nodule group was much higher than those of non thyroid nodules group. (5) The prevalence rate of breast hyperplasia of females under the age of fifty years was significantly higher than those of non thyroid nodule group (P<0.001). Conclusion The prevalence rate of thyroid nodules is high. It is related to gender, age, occupation and estrogen. Effective measures should be taken to change people's bad habits, blood sugar control and blood pressure, reduce BMI and work tension in order to reduce the incidence of thyroid nodules.

Objective To evaluate the value of MRI in the diagnosis of complex congenital heart disease.Methods Twenty-one patients with complex congenital heart disease,who had undergone MRI examination were enrolled in this research.The MRI data of every patient was analyzed and abnormalities of anatomy was counted by two experienced cardiovascular radiologist.Surgical diagnosis (17 cases) or consistent diagnosis (4 cases) of ultrasonic,cardiac catheter and cardiac CT was regarded as reference standards.Accuracy and misdiagnosis rate were obtained.Results Twenty-one patients had 63 main abnormalities,61 malformations was found by MRI examination,the diagnostic accuracy was 96.8％,and the misdiagnosis rate was 4.8％ (1 atrial septal defect (ASD) and 1 major aorta pulmonary collateral arteries (MAPCAS) were missed,1 arterialduct stump was misdiagnosed as patent ductus arteriosus (PDA).Conclusion MRI has excellent diagnosticaccuracy on complex congenital heart disease,it is another good noninvasive cardiac examination method beside ultrasonic.
