Objective To summarize the clinical effects of one stop hybrid approach for treating the tetralogy of fallot complicated with aorta pulmonary collateral arteries. Methods From Janu 2008 to June 2013, 79 cases of tetralogy of fallot were complicated with aorta pulmonary collateral arteries with mean age (5.4±3.9) years and weight (18.2±5.7) kg. All patients were diagnosed by echocardiography examination and accepted 64-row CT for demonstration of no dysplasia in pulmonary ressels, McGoon index was (1.7±0.6) and Nakata index was (176.7±7.3). 76 cases had aorta pulmonary collateral arteries for preliminary screening, and accepted cardiovascular angiography before operation. 3 cases were misdiagnosed before surgery and were confirmed by cardiovascular angiography after operation. Results There were 4 deceased cases with an operative mortality of 5.1%. 1 case died of lung infection and 3 cases died of refractory heart failure. In all aorta pulmonary collateral arteries, the smallest diameter was 2.5 mm, the largest was 9.4 mm, average (5.3±2.1) mm. 2 to 21 coils were implanted in respective case with an average of 10.2 coils per case. The maximum number of coils implanted in 1 single ressel was 9. The average number of ressels occluded was 3.7 (range from 1 to 11 ressels) in each case. One case received second closure due to re-open of collateral arteries on neo-vasculanigation. 14 cases had lung infection and 3 cases had pulmonary edema post operation. 75 cases were followed up for 3-72 months. 4 cases with post operative heart function of NYHA gradeⅢtoⅣand all other cases with gradeⅡon higher. Conclusions Peri-operative hybrid management for aorta-pulmonary collateral arteries can increase the operative success rates and reduce complications.

Objective:To discuss whether balloon atrial septostomy(BAS) can provide safe and effective left ventricular venting for venoarterial extracorporeal membrane oxygenation(V-A ECMO).Methods:From March 2017 to January 2019, 9 patients received BAS for left ventricular venting during V-A ECMO treatment in our hospital, including 5 males and 4 females, aged 12-72 years. There were 3 cases of severe myocarditis, 4 cases of low cardiac output after cardiac surgery, and 2 cases of acute myocardial infarction. Basic data, procedure data, outcome and follow-up were recorded.Results:BAS were successfully performed in 9 patients. Procedure time on average was 42.2 min. Anterior mediastinal hematoma occurred in 1 case. There were no other procedure-related complications in the rest cases. No pulmonary edema or thrombosis occurred in all 9 cases during ECMO. No closure procedure was performed.Conclusion:BAS is a safe and effective method for left ventricular venting. The procedure is conductive to the recovery of patients with severe left heart failure.

Objective : To examines the correlation between lifestyle factors and semen quality among sperm donors at Anhui human sperm bank. Methods : Demographic and lifestyle data were collected from 1 ,222 volunteers who donated sperm between January 2021 and December 2023 , and their association with semen quality was analyzed. Results : Univariate chi⁃square analysis revealed significant associations between several lifestyle factors and abnor mal semen parameters ( P < 0. 05 ) , including non⁃student status , frequent masturbation , short⁃term abstinence , low exercise frequency , frequent staying up late , smoking , drinking , and short sleep duration. Moreover, multivariate logistic regression analysis demonstrated that non⁃student status , longer abstinence time , and insufficient sleep were linked to abnormal semen volume. Additionally , abstinence time , exercise frequency , staying up late , smoking , and sleep duration were significantly correlated with abnormal semen concentration and sperm motility ( P < 0. 05) . Conclusion Analysis reveals a close relationship between semen quality and volunteers' lifestyles , including factors such as abstinence time , staying up late , sleep duration , smoking , drinking , and exercise frequency.

Objective : To analyze the characteristics of males with autologous sperm preservation(ASP) in Anhui human sperm bank , and to explore the future direction of ASP in human sperm bank. Methods : The basic information of males applied for ASP in Anhui human sperm bank from January 2019 to December 2023 was retrospectively analyzed. Results : During this period , there were 424 males applied for ASP. 93. 40% (396/424) came from Anhui Province , of which 46. 46% (197/424) came from Hefei. The age range of them was 15 to 59 years old. 66. 04% (280/424) had a college degree or above. 23. 11% (98/424) were employees of public institutions or enterprises. 26. 89% (114/424) were unmarried and 89. 39% (379/424) were childless. 67. 45% (286/424) patients applied for ASP because of assisted reproductive technology treatment. 15. 33% (65/424) patients did it due to tumors , among which testicular cancer, lymphoma , leukemia and seminoma were the main reasons. A total of 1 163 semen samples were saved , and 53 males had used their sperm. Conclusion Only a few people applied for ASP , and the characteristics of males with ASP can be used to further strengthen publicity for key groups , especially cancer patients , so as to benefit more people with autologous sperm preservation.
