Objective:To explore the surgical technique and results of three-dimensional aortic valve anatomic repair for bicuspid aortic valve (BAV) with aortic regurgitation (AR).Methods:This is a retrospective case series study. From August 2021 to December 2023, 130 consecutive patients with BAV-AR underwent aortic valve anatomic repair at the Department of Cardiothoracic Surgery, Zhongshan Hospital, Fudan University,and the data were retrospectively analyzed. There were 115 males and 15 females, aged (38.6±11.7) years (range: 15 to 67 years). All patients received modified aortic root reconstruction, to do three-dimensional root remodeling, including the basal ring, sinus of Valsalva and sino-tubular junction simultaneously. Perioperative and follow-up data were collected and analyzed. Comparisons between groups were performed using independent samples t-test, Wilcoxon paired signed-rank test, or χ2 test. Results:No patient transferred to valve replacement during the operation. The cardiopulmonary bypass time ( M(IQR)) was 109(34) minutes (range:67 to 247 minutes), and the aortic cross-clamp time was 76(26) minutes (range: 32 to 158 minutes). Preoperative transesophageal echocardiography showed 123 patients (94.6%) presented with moderate or severe regurgitation. Immediately postoperative transesophageal echocardiography showed no regurgitation in 22 patients (16.9%), trace regurgitation in 81 patients (62.3%) and mild regurgitation in 27 patients (20.8%). Follow up was completed in all patients, with a follow-up of 5.5(9.4) months (range: 0.1 to 27.6 months). No mortality was observed during follow-up. Echocardiography was obtained in 112 patients at the latest follow-up, including no regurgitation in 4 patients (3.6%), trace regurgitation in 58 patients (51.8%), mild regurgitation in 45 patients (40.2%), moderate regurgitation in 4 patients (3.6%), and severe regurgitation in 1 patient (0.9%). Conclusion:For patients with BAV-AR who have good valve quality and no severe aortic sinus dilation, the recent outcomes of three-dimensional anatomical repair technique, focusing on overall remodeling of the aortic root, are satisfactory.

Objective : To investigate the trends in incidence of malignant tumors in Yongkang City, Zhejiang Province from 2013 to 2019, so as to provide insights into formulation of the malignant tumor control strategy. Methods: Data pertaining to the incidence of malignant tumors from 2013 to 2019 were captured from the Zhejiang Chronic Disease Monitoring Information System. Based on the International Classification of Diseases 10th Revision (ICD-10) and data from the national population census, the constituent ratio, crude incidence and Chinese population-standardized incidence of malignant tumors were estimated, and the trends in incidence of malignant tumors were investigated using annual percent change (APC). Results: The annual mean crude incidence and Chinese population-standardized incidence of malignant tumors were 356.75/105 and 226.97/105, which both appeared an overall tendency towards a rise (APC=5.887% and 4.815%, both P<0.05). The crude incidence of malignant tumors appeared a tendency towards a rise among both men (APC=3.860%, P<0.05) and women (APC=8.534%, P<0.05) from 2013 to 2019, and the Chinese population-standardized incidence of malignant tumors appeared a tendency towards a rise among women (APC=8.392%, P<0.05). The largest increase in the crude incidence of malignant tumors was seen among women at ages of 15 to 44 years (APC=11.599%, P<0.05). In addition, the Chinese population-standardized incidence of lung cancer, colorectal cancer and thyroid cancer all showed a tendency towards a rise among men (all P<0.05), and the Chinese population-standardized incidence of lung cancer and thyroid cancer both appeared a tendency towards a rise among women (both P<0.05). Conclusions The incidence of malignant tumors showed a tendency towards a rise in Yongkang City from 2013 to 2019, and the elderly and young females are high-risk populations for malignant tumors. Lung cancer, thyroid cancer and colorectal cancer are cancers that should be given a high priority.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Cryptorchidism is one of the common diseases in children’s genitourinary system. Surgery is the first choice for clinical treatment. Testicular atrophy is a serious complication after operation. The related risk factors of testicular atrophy include the age of operation, the position of testis before operation and the mode of operation. At present, the possible treatments for testicular atrophy are hormone therapy, stem cell therapy and so on. This article reviews the related risk factors, fertility, diagnosis and treatment of testicular atrophy after orchiopexy in children.

Objective:To evaluate the outcomes of aortic root repair in acute type A aortic dissection (ATAAD) with aortic sinus involvement.Methods:The clinical data of patients with ATAAD involving the aortic sinus and an aortic root diameter of ≤45 mm who were treated from January 1, 2015, to December 31, 2016, were collected. Patients were divided into group A (involvement of one aortic sinus or part of one aortic sinus) and group B (involvement of more than one aortic sinus). The effectiveness of aortic root repair in ATAAD with sinus involvement was analyzed by comparing the preoperative imaging characteristics and postoperative results between the two groups.Results:The study cohort comprised 155 patients, including 100 patients in group A and 55 in group B. There were no differences between the two groups in baseline characteristics, aortic root diameter, 30-day mortality, and complication rates. During an average follow-up of(49.1±14.6) months, there was no difference between the two groups in the survival rate (92.0% vs. 89.5%, P=0.61). The aortic root diameter at follow-up showed no progressive expansion compared with preoperatively in either of the two groups[(38.1±3.6) mm vs. (37.9±3.5)mm, P=0.92, A; (38.4±4.1) mm vs. (38.3±3.6) mm, P=0.74, B]; furthermore, there was no difference between the two groups in aggravation of aortic regurgitation. Conclusion:Aortic root repair achieves satisfactory medium-term outcomes in ATAAD with more than one aortic sinus involved, but the long-term outcomes need to be evaluated.

Objective:To summarize the clinical characteristics and surgical treatment experience of pregnant women with acute Stanford type A aortic dissection.Methods:From January 2005 to December 2018, a total of 12 patients with acute Stanford type A aortic dissection were treated in Zhongshan Hospital affiliated to Fudan University. Two patients died of sudden aortic dissection rupture during emergency CTA examination. The other 10 patients underwent surgical treatment, the age was 22-40 years[mean(30.7±5.8) years], the pregnancy was 15-39 weeks[mean(28.8±6.5) weeks], two cases in the second trimester of pregnancy, seven cases in the third trimester of pregnancy and one case in puerperium. Among them, seven cases were Marfan syndrome, one case was bicuspid aortic valve malformation, two cases were complicated with pregnancy hypertension.Results:One case died during perioperative period and died of rupture of abdominal aortic dissection in twelfth day after operation. One fetus was diagnosed as stillborn before operation. Before December 2013, six patients underwent surgeries, the mean cardiopulmonary bypass time was(96.8±16.5)min, aortic occlusion time was(70.8±19.3)min, intensive care unit time was(3.4±2.3) days, ventilator-assisted mechanical ventilation time was(21.6±15.6)h. After January 2014, four patients underwent surgeries, the mean cardiopulmonary bypass time was(202.3±6.4)min, the aortic cross-blocking time was(137.5±10.3)min, circulatory arrest time was(27.3±8.8)min, intensive care unit time was(12.0±5.7) days, and the ventilator-assisted mechanical ventilation time was(40.3±24.4)h. The postoperative complications included tracheotomy in two cases, hemodialysis in one case, poor wound healing in one case. One patient who had been treated with Bentall was followed up to sixth year and died of progressive rupture of descending arch dissection. One patient was followed up to seventh year after Bentall surgery, redo Bentall and Sun’s procedure were performed because of artificial valve infection, and was discharged uneventful. No adverse cardiovascular events occurred in other patients.Conclusion:Surgical treatment should be actively considered in pregnancy complicated with acute Stanford type A aortic dissection. Multi-disciplinary team cooperation can effectively improve the safety and effect of operation.

Objective    To evaluate the feasibility, safety, and short-term effect of minimally invasive ascending aorta surgery through a right anterior thoracotomy via the second intercostal incision. Methods    The clinical data of 13 patients who underwent minimally invasive ascending aorta surgery (including minimally invasive Bentall operation in 7 patients, minimally invasive Wheat operation in 2 patients, and minimally invasive ascending aorta replacement in 4 patients) through a right anterior thoracotomy via the second intercostal incision in our center from October, 2019 to September, 2020 were retrospectively analyzed. There were 12 males and 1 female at age of 19-69 (52.4±13.7) years. Results    The aortic cross-clamping time was 84.3±18.3 min. Three patients received blood transfusion, with the rate of 23.1%. The drainage volume in the first 24 hours after operation was 214.5±146.3 mL, with no redo for bleeding. The duration of mechanical ventilation was 19.0±11.3 hours and the length of intensive care unit stay was 1.8±1.3 days. The drainage tube was removed 2.5±1.0 days after operation. All the 13 patients recovered and discharged 6.4±2.0 days after operation, with no dead patients found. All patients survived with New York Heart Association (NYHA) functional classⅠandⅡduring a median follow-up of 8 months. Conclusion    Minimally invasive ascending aorta surgery through a right anterior thoracotomy via the second intercostal incision may be a safe and effective method with less injury and quick recovery.

Cryptorchidism is the most common developmental abnormality of male genitourinary system and the most common cause of non-obstructive azoospermia in adults. This article reviews the research progress on the correlation between the age, unilateral and bilateral, position, hormone adjuvant therapy of childhood cryptorchidism and adult infertility and the mechanism of infertility, in order to improve the protection of the prepubertal testis by clinicians. Orchiopexy is recommended as early as possible at the age of 6 to 12 months, in order to maintain spermatogenesis and improve the fertility of adults.
