Objective To explore the sex difference in clinical manifestations, echocardiographic features and prognosis of patients with bicuspid aortic valve (BAV) combined with moderate to severe aortic stenosis (AS). Methods The clinical data and echocardiographic follow-up parameters of patients diagnosed with BAV combined with moderate to severe AS at Zhongshan Hospital, Fudan University, from July 30, 2010 to August 1, 2015 were retrospectively collected. The composite endpoint was defined as all-cause mortality or surgical intervention. Kaplan-Meier survival curve and log-rank test were used to compare the risk of composite endpoint events between male and female patients, and Cox regression models were used to analyze independent risk factors for composite endpoint events. Results A total of 144 patients were included, with 69 males and 75 females, and a median age of 60 years. Compared to males, female patients were younger (58[46, 65] years vs 61[54, 67] years, P＝0.046), had a lower proportion of aortic valve calcification (61.1% vs 81.1%, P＝0.009), and a higher peak transvalvular pressure gradient (72[59, 88] mmHg vs 63[55, 72] mmHg, P＝0.002). In terms of left ventricular remodeling types, the proportion of concentric remodeling was higher in females than in males (36.0% vs 15.9%, P＝0.006), while the proportion of eccentric hypertrophy was lower in females than in males (10.7% vs 29.0%, P＝0.006). The proportion of female patients classified as New York Heart Association (NYHA) functional class Ⅲ-Ⅳ was higher than that of males (45.3% vs 17.4%, P＜0.001), and left ventricular ejection fraction was higher in females (68%[65%, 72%] vs 65%[60%, 70%], P＝0.003). With a median follow-up of 49 months, Kaplan-Meier survival analysis showed that the risk of composite endpoint events was higher in females than in males (P＜0.001). Independent risk factors for composite endpoint events included female (HR＝1.74, 95%CI 1.02-2.96, P＝0.042), severe AS (HR＝1.99, 95%CI 1.18-3.36, P＝0.010), and NYHA functional class Ⅲ-Ⅳ (HR＝2.08, 95% CI 1.24-3.47, P＝0.005). Conclusions Sex significantly affects the clinical manifestations, echocardiographic characteristics, and prognosis of patients with BAV combined with moderate to severe AS, suggesting that sex-specific echocardiographic assessment and follow-up monitoring should be conducted for these patients.

Objective To build a comprehensive evaluation system for the operating benefit of clinical departments in cancer hospitals,so as to provide data support for the fine operation management of hospitals.Methods Literature review and semi-structured interview were used to form the index pool.Two rounds of Delphi expert consultation were used to determine the index of the evaluation system,and the analytic hierarchy process was used to determine the index weight.Finally,the weighted TOPSIS was used for empirical case analysis.Results The positive coefficient in the two rounds of Delphi expert consultation were 82.6％and 100％,the authority coefficient was 0.808,and the coordination coefficient was between 0 and 1.All indexes at all levels passed the consistency test.Finally,a comprehensive evaluation system consisting of 4 dimensions,19 indexes in surgery,16 indicators in radiotherapy and 16 indicators in internal medicine was constructed.Indicators at all levels were tested for consistency,resulting in the construction of a comprehensive evaluation system consisting of 4 dimensions,19 indicators for surgery and 16 indicators each for radiotherapy and internal medicine departments.Conclusion The comprehensive evaluation system of operating benefit of clinical departments in cancer hospitals can help hospitals and departments to find out the shortcomings of operation,build the path of operating benefit improvement,and realize the connotation improvement and high-quality development of hospitals.

Objective To evaluate the effects of combining immune checkpoint inhibitors,trastuzumab,and chemotherapy on the left and right ventricular function in patients with advanced gastric adenocarcinoma expressing human epidermal growth factor receptor 2(HER2).Methods 25 patients with advanced HER2-positive gastric adenocarcinoma who received HER2-ASTRUM therapy(sruili monoclonal antibody combined with trastuzumab and DOS regimen)underwent echocardiographic examinations at baseline(T1),after completion of 4 cycles(T2),and 6 cycles(T3)of chemotherapy.Left ventricular strain,left ventricular myocardial work,right ventricular strain,and ejection fraction were further analyzed.Results Compared with T1,both T2 and T3 showed a decrease in left ventricular ejection fraction(LVEF),(T1,T2,and T3 were[67.3±2.7]％,[63.0±2.9]％and[61.3±3.2]％,P＜0.05).T3 showed a decrease in right ventricular ejection fraction(RVEF),([59.3±7.8]％vs[43.7±6.6]％,P＜0.05),while T2 showed no significant change in RVEF.Both right ventricular global longitudinal strain(RVGLS),(T1,T2,and T3 were[-25.7±5.7]％,[-22.4±5.3]％and[-19.1±3.6]％,respectively;P＜0.05)and right ventricular free-wall longitudinal strain(RVFWLS),(T1,T2,and T3 were[-20.9±4.7]％,[-18.9±4.1]％and[-16.1±3.9]％,P＜0.05)decreased in all three time points.The global work index(GWI)was lower in T2 and T3 than in T1(P＜0.05),while the global constructive work(GCW),global wasted work(GWW),and global work efficiency(GWE)did not show significant changes.Conclusions Combination of trastuzumab,immune checkpoint inhibitors,and chemotherapy has an impact on left ventricular strain,LVEF,and right ventricular strain,as well as GWI,in HER2-positive patients with gastric adenocarcinoma.Left ventricular global longitudinal strain(LVGLS),RVFWLS,and RVGLS can more sensitively monitor cardiac function and detect cardiac dysfunction related to cancer treatment in a timely manner.

Objective To analyze the changes in left ventricular deformation function in patients with diffuse large B-cell lymphoma(DLBCL)treated with different doses of anthracycline chemotherapy using 3D speckle-tracking imaging(3D-STI).Methods 66 DLBCL patients receiving anthracycline chemotherapy were enrolled.Based on the cumulative dose of anthracycline received,the patients were divided into a high-dose group(＞360 mg/m2,n=39)and a low-dose group(≤360 mg/m2,n=27).Patients underwent transthoracic echocardiography before chemotherapy and within one week after completion of the entire chemotherapy cycle.Left ventricular global longitudinal strain(LVGLS),left ventricular global circumferential strain(LVGCS),and other indices were analyzed using 3D-STI to assess changes in left ventricular deformation indices after chemotherapy and between two groups.Results Compared to baseline,DLBCL patients showed significant reductions in LVGLS,LVGCS and left atrial global longitudinal strain(LAGLS)after treatment completion(P＜0.001).When comparing the high-dose group with the low-dose group,there was a significant increase in relative LVGCS change rate at the end of chemotherapy(21.12[6.52,35.37]vs 5.49[-14.73,27.01];P=0.03).However,there were no statistically significant differences in relative left ventricular ejection fraction(LVEF),LVGLS,LVGCS,LVEF change rate,or LVGLS change rate between the two groups.Conclusions 3D-STI can be a potential method to identify the sub-clinical deterioration of left ventricular systolic function in patients received anthracycline chemotherapy,the difference of change rate of LVGCS may predict the variation of sub-clinical deterioration of left ventricular function between patients received high and low doses of anthracycline chemotherapy.
