Objective To realize the application of mini-PACS based on Web.Methods According to the actuality of our hospital,the reasonable structure of Database,Network Topol and application program are designed.Conclusion The cheap cost and reasonable design is the key of mini-PACS' application to hospitals.

Objective Discuss clinical type and treatment of postoperative digestive tract fistula and associate complications of esophageal or cardiac cancer.Methods Analized clinical manifestations and treatment retrospectively of 53 cases of digestive tract fistula after operation of esophageal or cardiac cancer from January,2010 to December,2012.Results All the 10 undergoing surgery are cured by reoperation.2 died of mediastinal infection and sepsis.4 died of respiratory failier,malnutrition,left and right bronchal fistula,respectively.Conclusion There are 4 types of fistula:Ⅰ type of sepsis,Ⅱ type of respiratory failure,Ⅲ type of thoracic infection,Ⅳ type of neck inection.Reoperation within 24 hours is the key of suscessful repairment of intrathoracic anastmotic leakage.Bronchal fistula or respiratory failure caused by multiple thoracic encapsulated effusion is also the indication of surgery.Complete lung reexpansion and complete drainage is the key.Mini-invasive VATS is the method of exact drainage.

Objective To assess the effect of ultrasound-guided multiple-spot sector stereotaxis in unipolar cooling cycle radiofrequency ablation of hepatic carcinomas. Methods Ninety-six patients with 112 liver malignancies were treated with ultrasound-guided percutaneous radiofrequency ablation using multiple-spot sector stereotaxis method. Conventional multi-section ultrasound scanning was performed to determine the exact location of tumors. Contrast enhanced ultrasound (CEUS) was performed 15 minutes after treatment to determine whether the tumors were completely inactivated. Contrast enhanced CT (CECT) and CEUS were performed 1 month after treatment to evaluate the therapeutic effect. Results A total of 293 punctures were performed for 112 tumors, technical successful rate with a successful rate of puncture was 91.81% (269/293). CEUS showed no blood flow signals in the tumors 15 minutes after therapy. One month after therapy, CT showed the volume of tumors shrunk, no enhancement was found in 100 tumors (100/112, 89.29%), while partial reinforcement was noticed in 12 tumors (10.71%). Meanwhile, CEUS showed no enhancement in 90 tumors (90/103, 87.38%), when partial reinforcement was noticed in 13 tumors (13/103, 12.62%). Conclusion Ultrasound-guided multiple-spot sector stereotaxis unipolar cooling cycle radiofrequency ablation is an effective and reliable method to treat hepatic carcinomas.

To establish a RP-HPLC method for the determination of content of sisomicin sulfate and sodium chloride injection. Thermo Aminoglycoside RP 18(4. 6 mm ×150 mm, 3 μm)column was used. The mobile phase consisted of Sodium heptane sulfonate solution(take 6 g of sodium heptane sulfonate, add 0. 1 mol/L potassium dihydrogen phosphate solution and dilute to 1 000 mL, adjust the pH to 1. 5 with phosphoric acid)- acetonitrile(77∶23). The detection wavelength was 205 nm, the flow rate was 1. 0 mL/min. and the column temperature was 35 °C. The separation of sisomicin peaks with related substances and the degradation products was good. The linear range of the peak area with sisomicin was 0. 010 024-1. 002 4 mg/mL(Y=4. 210 2×106 X+9. 107 0×103, r=0. 999 9, n=7), the detection limit was 0. 6 ng, the limit of quantification was 2 ng, and the recovery rate was at 99. 1%-100. 9%(RSD< 1. 0%, n=9). The method is sensitive, exclusive, accurate and suitable for the determination of sisomicin. Compared with the antibiotic microbiological test method, the specificity is better, the confidence interval of the result is narrowed, and the test time is saved.
