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 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 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 summarize the clinical features,diagnostic and treatment experience of severe hand,foot and mouth disease(HFMD) cases receiving mechanical ventilation from Jan 1 to Sep 6,2009 in our hospital and provide reference for reducing the occurrence of neurogenic pulmonary edema(NPE) and mortality. Methods 147 severe HFMD who received mechanical ventilation were analyzed by a retrospective investigation. Results 85.0% children were less than 3 years old and 100% patients had a fever. The mechanical ventilation occurred within 1 to 4 days after fever (3.06 ± 1. 02) d. Neurological complications presented as bad spirit,easy surprised, involuntary movement of the extremities and lethargy. Respiratory system complication presented as polypnea, hypepnea and irregular rhythm. Circulatory system complication presented as heart rate increase or decrease, hypertension or hypotension, piebald skin and low limb temperature.Some of the children had high white blood cell counting,glucose and lactic acid of the blood. The EV71-PCR positive rate was 34. 7% for throat swabs,and 42. 2% for anal swabs. Chest X-ray presented as increased broncho vascular shadows, exudation or nonapparent abnormality. Only three children were dead, fatality rate was 2. 0%. Conclusion The HFMD cases in this outbreak are relatively more serious,and change rapidly. It's difficult to treat as soon as NPE appeared,and it has high fatality rate. Early recognition of critical patients,timely giving mechanical ventilation,and the comprehensive treatment can reduce NPE incidence and the mortality.

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.

BACKGROUND:As an oral anticoagulant drug, many experiments have proved that rivaroxaban can prevent the deep venous thromboembolism after the hip arthroplasty. The foreign literatures indicate that it can significantly reduce the incidence of deep venous thromboembolism after extending the treatment course to 35 days. But there is no significant conclusion at home, and the safety of drugs after extentding the course has not been confirmed. OBJECTIVE:To analyze the efficacy and safety of rivaroxaban versus low-molecular-weight heparin for the prevention of deep venous thrombosis after the hip arthroplasty. METHODS:106 patients with primary unilateral hip arthroplasty in the Second Clinical Medical College of Shanxi Medical University between March 2011 and September 2012 were selected. The patients were randomly divided into rivaroxaban group and low-molecular-weight heparin group. The patients in two groups were given drugs at 6 hours after replacement, the patients in the rivaroxaban group were given rivaroxaban 10 mg/d with the course of 5 weeks;the patients in the low-molecular-weight heparin group were given low-molecular-weight heparin 4 100 U/d with the course of 2 weeks. RESULTS AND CONCLUSION:The review and fol ow-up results showed there was no deep vein thrombosis or symptoms of deep vein thrombosis in patients of the rivaroxaban group after replacement, while seven cases (13%) of deep vein thrombosis were observed in the low-molecular-weight heparin group, and there was significant difference in the incidence rate of deep vein thrombosis between two groups (P<0.05). There were no significant differences in venous blood hemoglobin level, platelet level and coagulation function before and after replacement, as wel as the drainage volume and subcutaneous ecchymosis area after replacement of the patients received unilateral hip arthroplasty between two groups (P>0.05). The results indicate that ful course of rivaroxaban has clear effect and reliable security in the prevention of deep venous thrombosis after hip arthroplasty.
