ABSTRACT
@#Objective To analyze the correlation between the gray value of epicardial fat and the prognosis of patients with atrial fibrillation (AF) treated by thoracoscopic radiofrequency ablation. Methods The clinical data of 97 patients, including 75 males and 22 females with an average age of 57.8±9.4 years, who underwent thoracoscopic radiofrequency ablation in Fuwai Hospital from 2017 to 2018 were analyzed retrospectively. The left atrial fat volume and average gray scale were calculated by left atrial enhanced CT. According to the average gray scale of left atrial fat tissue, the patients were divided into three groups: a high gray scale group, a medium gray scale group and a low gray scale group. The patients were followed up at 3, 6 and 12 months after operation. The end point of follow-up was the recovery rate of sinus rhythm. Survival analysis was used to analyze the correlation between CT features of epicardial fat enhancement and prognosis. Results After adjustment of body mass index, body surface area, gender and left atrial end diastolic diameter, regression analysis showed that the fat gray of left atrial enhanced CT was correlated with the type of AF (OR=0.30, 95%CI 0.12-0.79, P=0.014). Cox regression analysis showed that the fat gray value of left atrial CT predicted the recurrence of AF after thoracoscopic radiofrequency ablation (OR=0.92, 95%CI 0.85-0.99). The Kaplan-Meier curve showed significant difference in the long-term recurrence rate of AF among the three groups (P=0.011). The lower left atrial fat enhanced CT gray scale was, the higher long-term recurrence rate of AF was. Conclusion The gray value of left atrial fat enhanced CT can effectively predict the recurrence of AF after radiofrequency ablation in thoracoscopic surgery.
ABSTRACT
By promoting the socialization of hospital logistics professional skill services, the logistics support ability and safety production supervision level can be improved. By using the theory and method of system dynamics, the income decision model of public-private-partnership projects in the energy station of Nankai hospital is established. Then, the qualitative factors in the decision-making model are transformed into calculable quantitative factors by using the mathematical method of fuzzy logic, and the reasonable charging interval negotiated between Nankai Hospital and the project company is given. According to the income range and in consideration of the balance of interests of all stakeholders, the concession period and the concession price are adjusted to provide decision-making and analysis reference for energy station construction projects.

ABSTRACT
ObjectiveTo evaluate the clinical effect and reliability of basiliximab as immune inducer combined with classic triad resisting immune rejection scheme in preventing immune rejection after heart transplant.MethodsWe continuously collected the clinical information of 214 patients undergoing heart transplantation from June 2004 to January 2011.Basiliximab was used at 1st h before heart transplant and 4 days after the operation by 20 mg each time.Triad resisting immune rejection scheme included methylprednisone,cyclosporine A and mycophenolate mofetil.The endocardial biopsy was done to diagnose rejection postoperatively,and the severity of acute rejection was graded according to the standardized criteria of the International Society for Heart and Lung Transplantation (ISHLT).The recipients were followed up for 1year after the surgery,the data of the endocardial biopsy and rejection were collected,and the postoperative complications and deaths were observed.Results The first time of recipients to accept the endocardial biopsy was 20.1±7.3 days postoperatively,including 63 (29.4％) cases of Grade Ⅰ A,8 (3.7％) cases of grade Ⅰ B,and 12 (5.6％) cases of grade Ⅱ.One year after operation,143 recipients accepted the endocardial biopsy,including 29 (20.3％) cases of grade Ⅰ A,1(0.7％) case of grade Ⅰ B,12 (7.7％) cases of grade Ⅱ.During hospitalization,5 recipients died,including 3 cases due to transplant heart failure,1case due to multiple organ failure and 1due to sudden death.One year after discharge,there were 2 deaths,including one case of serious rejection and 1case of multiple organ failure One month after operation,infection occurred in 7 cases (3.3％),and acute renal insufficiency in 11cases (5.1％).ConclusionCombined use of Basiliximab with triad resisting immune rejection scheme was a kind of safe and effective therapy to prevent early acute rejection after heart transplantation.
