An experimental study was designed on the treatment of 8 superficial burn wounds and 5 wounds after removing the split-thickness skin grafts with 200GS permanent magnetic flat dressings, and some of the wounds were chosen at random which did not received any treatment and would be served as control. It was noted that the volume of exudate in the treatment group was 11.9 50.7％ less than that of the control group, and the total protein, the albumin and globulin contents in the treatment cases were far less in exudate than those of the control cases. It was concluded that the magnetic therapy not only decresed the exudate, but also diminished the amount of total protein, albumin and globulin in the exudating fluid and it was of benefit to wound recovery.

Abstract： Objective To assess the effects of three different palliative procedures including modified BlalockTaussig (B-T) shunt, Waterston shunt, and reconstruction of right ventricularpulmonary artery (RV-PA) continuity for pulmonary atresia with ventricular septal defect (PAVSD). Methods We retrospectively analyzed the clinical data of 93 patients with PAVSD who had undergone palliative surgical procedures including modifie BT shunt, Waterston shunt, and RVPA econstruction in Fu Wai Hospital from September 1998 to September 2008. There were 53 males and 40 females, aged from 14.0 days to 14.4 years, with the body weight ranged from 3.6 to 33.0 kg (9.9±6.3 kg). According to International Congenital Heart Surgery Nomenclature and Database Project, these patients were categorized into 2 groups: 64 of type Ⅰ and 29 of type Ⅱ. The most common associated anomaly is rightsided aortic arch (except for ventricular septal defect). The application of the three kinds of palliative surgical procedures in staged management of PAVSD and the followup results were statistically analyzed. Results The corrective rate of the three palliative procedures were 28.12% (18/64) for modified BT shunt, 7.14%(1/14) for Waterston shunt, and 66.67% (10/15) for RV-PA reconstruction, respectively. RV-PA reconstruction had a significantly higher corrective 〖CM(1585mm〗rate than the other two surgical procedures (P=0.016). The percutaneous oxygen saturation (SpO2) increased by 4%59% and Nakata index by 31-104 mm2/m2. No tortuous pulmonary artery was found under echocardiogram or angiocardiography after palliative operation. The perioperative mortality of both surgical stages was 10 patients. Twostage radical surgery was successfully performed for 25 patients, among whom 20 were followed up till May 2009. During the followup, one died suddenly, 15 were classified as New York Heart Association (NYHA) Ⅰ, and 4 as NYHA Ⅱ. Conclusion The surgical management of PAVSD needs to be improved continuously. Compared with shunting procedures, the RVPA reconstruction is a better palliative operation method, and the modified B-T shunt is preferred in younger patients.
ObjectiveIn order to provide a data base for fund project applicants and funding priorities, we would summarize the basic situation and key points of basic research in liver transplantation by analyzing the projects funded by the Natural Science Foundation of China (NSFC) in the field of liver transplantation.MethodsThrough the big data knowledge management and service platform of NSFC, internet-based science information system, and shared service network of NSFC, we searched the funding project information in the liver transplantation relevant field from 2010 to 2019, then analyzed the effectiveness of the Young Scientists Fund of NSFC in promoting young researchers and the research focus and development direction of funding projects.ResultsIn the latest 10 years, NSFC persistently and stably funded the basic research in the field of liver transplantation, with the total number of funding projects was 387, and the funding budget was 198.215 million yuan. The main types of funding projects were the General Program and the Youth Science Fund. There were 210 General Program project (54.3%) with an amount of 113.14 million yuan (57.1%), 127 Young Scientists Fund (32.8%) with an amount of 27.9 million yuan (14.1%), and 22 Fund for Less Developed Regions (5.7%) with an amount of 9.03 million yuan (4.6%). Sun Yat-sen University and Zhejiang University were far ahead of other supporting institutions in both the total number of projects undertaken and the amount of funds granted. The youth/surface ratio reached as high as 72.2% (13/18). The conversion rate of Young Scientists Fund to higher-level projects reached about 50%, which was significantly higher than the overall level of 24.7% (21/85) in the field of liver transplantation. The funding projects were mainly distributed in application code H0318 (liver regeneration, liver protection, liver failure, and artificial liver, 58, 15.0%), H0321 (organ transplantation of digestive system, 169, 43.7%), and H1006 (organ transplantation and transplantation immunity, 50, 12.9%). The main research fields were transplantation immunity and liver injury and liver protection. At the same time, projects such as graft function and complications of liver transplantation were also funded. There were few studies on the immune status of long-term survival in patients after liver transplantation and the mechanism on prevention of immunosuppressant-related diseases.ConclusionsThe NSFC has a great leading effect on the discipline development and talent cultivation of liver transplantation. However, there are still some problems in the discipline layout, such as the lack of attention to the mechanism of long-term graft function and chronic immune rejection.
