Objective To discuss the effica of central venous catheter drainage in interventional treatment of abdominal surgical complications.Methods The clinical data of 72 cases of abdominal surgical diseases were retrospectively analyzed,the complications included 23 cases of ascites,19 cases of bile leakage,8 cases of pancreatic fistula,7 cases of pancreatic necrosis and 15 cases of abdominal abscess,they all underwent percutaneous central venous catheter drainage under the guidance of ultrasound or CT.Results Central venous catheter was placed in 72 cases successfully in one time,the cathetem were kept for 2 to 37 days,5 discharged cases with catheter underwent regular reexamination in the clinic.3 cases of ascites were replaced for catheter shedding; 17 cases for occlusion recieved catheter irrigation and guidewire dredging;2 cases of pancreatic necrosis and 1 case of peripancreatic abscess were cured by repeated puncture and replacement of large-bore catheter.2 cases of pancreatic necrosis,1 case of pancreatic fistula and 1 case of appendicitis underwent laparotomy finally; 1 case of postcholecystectomy bile leakage underwent endoscopic stent therapy; 1 cases of severe pancreatitis complicated with ARDS was treated in ICU.Conclusion Central venous catheter drainage guided by ultrasound or CT for treatment of abdominal surgical complications was not only safe but also effective,and is worthy of popularization and application.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.

Background Many studies and clinical trials of pharmacologic vitreolysis are already under way to try to improve vitreo-retinal surgery and to liquefy and detach the vitreous from the retina ultimately, including chondroitinase,hyaluronidase,dispase and plasmin. However, there has not been any report on purification of human plasminogen from cord blood plasma and inducing posterior vitreous detachment of the animal eye at present.Objective This study was designed to isolate and purify the production of human plasminogen (Plg) from cord blood plasma with ethanol precipitation and evaluate the efficacy of Plg in inducing posterior vitreous detachment (PVD).Methods Human Plg was Separated and purified from cord blood plasma by ethanol precipitation method. The protein band corresponding to Plg with molecular mass of 92 000 was revealed in SDS-PAGE and confirmed by MALDI-TOF and Mascot database. Anion-exchange chromatography and plasminogen activity assay kit were used to obtain purified Plg with biological activity. Twenty-five fresh pig eyes were enucleated and assigned to 5 groups and 5 eyes for each group. The normal eyes were used as control group. Balanced salt solution(BSS)of 0.1 ml was intravitreally group and standard substance group. All of the eyes were then incubatedfor 60 minutes under the 37 ℃. Retinal histopathology and ultrastructure were examined under the light microscopy, scanning electron microscopy ( SEM ) and transmission electron microscopy (TEM). Results The Plg with potential fibrinolytic activity was successfully extracted and purified from cord blood plasma by ethanol precipitation method. No posterior vitreous detachment (PVD) was seen in normal control group, BSS group and r-SK group following the intravitreal injection under the sem. However,PVD was demonstrated in r-SK+ Plg group and standard substance group under the SEM. The inner limiting membrane ( ILM ) and the retina were well preserved in all of the experimental eyes. No retinal morphology and ultrastructural abnormality were found under the light and SEM and TEM. Conclusion Ethanol precipitation is a feasible way to isolate and purify Plg from human cord blood plasma. Extracted Plg shows potential fibrinolytic intravitreal injection of Plg.
