Objective To explore the epidemiological characteristics of gouty arthritis in Northwest China from 2023 to 2025, and to formulate preventive intervention measures. Methods By retrospectively analyzing the case data of medical institutions in Northwest China from January 2023 to June 2025 (a total of 8 139 cases), the incidence trend and population distribution characteristics of gouty arthritis in this area were analyzed. Multivariate logistic regression analysis was performed to identify risk factors. Results From 2023 to 2025, the prevalence rate of gouty arthritis in adult residents in Northwest China was 3.74% (304/8 139). Among the sites affected by gouty arthritis, the metatarsophalangeal joint accounted for the highest proportion (P<0.05). From the perspective of age distribution, the prevalence rate was the highest in 40-59 years old group (5.90%), followed by 66-80 years old group (4.21%) and >80 years old group (2.75%). The incidence rate in 40-65 years old group was higher than that in the other age groups (P<0.05). High blood uric acid and creatinine, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome were risk factors affecting gouty arthritis in Northwest China (P<0.05). Conclusion High blood uric acid level, high creatinine level, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome are risk factors influencing gouty arthritis in Northwest China. Based on the above factors, this study proposes comprehensive prevention strategies from the individual, community and public health levels to provide a scientific basis for reducing the incidence rate of gouty arthritis.

Objective:To analyze and explore the selection of secondary intervention strategies for residual issues following congenital aortic valve disease surgery in children, as well as to evaluate their prognostic efficacy.Methods:A retrospective analysis was conducted on the clinical data of 41 children with residual issues after congenital aortic valve disease surgery, who were treated at the Department of Cardiovascular and Thoracic Surgery, Shanghai Children's Medical Center, between January 2013 and August 2024. Among them, 25 were male and 16 were female, with a mean age of(116.8±45.1)months and a mean weight of(40.0±20.2)kg. The mean interval for secondary intervention was(60.0±36.4)months. The residual issues included aortic valve insufficiency(20 cases), aortic valve stenosis(11 cases), and combined aortic valve insufficiency and stenosis(10 cases).Results:Secondary interventions included aortic valve repair(7 cases), mechanical valve replacement(20 cases), Ross procedure(13 cases), and Ozaki procedure(1 case). Additionally, 5 cases with left ventricular outflow tract stenosis underwent concomitant Konno surgery.One case of early postoperative in-hospital death occurred, with a mortality rate of 2.4%, primarily due to acute left heart failure and multiple organ dysfunction. The average follow-up period for surviving children was( 64.6±34.5) months(5-147 months), with no mid- to long-term mortality. Follow-up results showed that In surviving children, the left heart showed significant reduction in size postoperatively, with the LVEDD Z-score decreasing from 1.24±2.23 before surgery to -0.97±1.48( P=0.001). Postoperative LVEF 0.66±0.06 showed no significant difference compared to pre-reintervention 0.68±0.10( P=0.140). In aortic stenosis(AS) patients, the peak transvalvular pressure gradient decreased from(69.5±19.8) mmHg(1 mmHg=0.133 kPa) preoperatively to(25.1±10.9) mmHg postoperatively( P=0.003). In aortic insufficiency(AI) patients, the width of the aortic regurgitation jet decreased from(5.8±1.1) mm preoperatively to(2.7±1.1) mm postoperatively( P=0.012). 97.5% of children maintained mild-to-moderate aortic regurgitation(jet width <4 mm), with only 1 case of moderate regurgitation(jet width 4.4 mm)remaining under close observation.Two children underwent reoperation on the aortic valve, with a tertiary intervention rate of 5.0%. One case underwent redo commissurotomy 21 months after aortic valve repair due to recurrent stenosis, and the other underwent mechanical valve replacement 34 months after the Ozaki procedure due to leaflet calcification and infective endocarditis. Mid-term follow-up revealed good cardiac function recovery in surviving children, with 87.5% achieving NYHA functional class Ⅰ/Ⅱ. Conclusion:Due to the demands of growth and development and the degenerative nature of valve tissue, residual issues are inevitable in the mid- to long-term following congenital aortic valve disease surgery in children, often necessitating secondary intervention. Given the lack of suitable autologous valve tissue, the use of aortic valve replacement has significantly increased in secondary interventions. The Ross procedure, as an ideal secondary intervention, demonstrates satisfactory mid-term follow-up outcomes. For children with high-risk factors for the Ross procedure, mechanical valve replacement also yields favorable prognoses.

Objective:To study the cardiac morphology and function of fetuses with different types of complete transposition of the great arteries(cTGA)by using fetal heart quantification(fetal HQ).Methods:A retrospective study was conducted on 50 fetuses diagnosed with cTGA through fetal echocardiography at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from July 2020 to December 2024. These cases were categorized into simple cTGA group( n=31)and complex cTGA group( n=19)based on the presence of concomitant cardiac anomalies. A control group of 160 normal fetuses with matched gestational ages was selected for comparison. Utilizing fetal HQ technology,the cardiac longitudinal diameter,transverse diameter,area,global sphericity index(GSI),left and right ventricular end-diastolic area(LVEDA,RVEDA),left and right ventricular fractional area change(LVFAC,RVFAC),left and right ventricular global longitudinal strain(LVGLS,RVGLS),and segmental sphericity index of 24 segments for both left and right ventricles(LVSI,RVSI)were measured. The analysis focused on comparing the differences among the simple cTGA group,complex cTGA group,and the control group. Results:Compared to the control group,the simple cTGA group exhibited significantly lower fetal GSI,LVEDA,RVFAC,and RVGLS(all P<0.05). Statistically significant differences were observed in LVSI segments 1-4 and 10-17,as well as RVSI segments 1-7,9,and 15-23 compared to the control group(all P<0.05). In comparison with the control group,the complex cTGA group demonstrated significantly reduced fetal GSI,LVFAC,LVGLS,RVFAC,and RVGLS(all P<0.05). Significant differences were noted in LVSI segments 5-8 and 10-14,along with RVSI segments 1-14 and 24 compared to the control group(all P<0.05). When compared to the simple cTGA group,the complex cTGA group showed significantly lower LVFAC,LVGLS,RVFAC,and RVGLS(all P<0.05),while GSI and LVEDA were significantly higher(all P<0.05). Statistically significant differences were observed in LVSI segments 3-4,6-8,and 17,as well as RVSI segments 10-19 between the complex cTGA group and the simple cTGA group(all P<0.05). Conclusions:The comprehensive parameters provided by Fetal HQ facilitate the assessment of cardiac morphology and function in cTGA fetuses,enabling a deeper understanding of the alterations in cardiac structure and function across different types of cTGA. This advanced analysis offers valuable reference information for clinical guidance during pregnancy.

Objective To investigate the association between lifestyle and risk of heart disease and diabetes in the elderly population in Xi'an City. Methods From January 2021 to January 2024, a staged cluster sampling method was used to investigate the lifestyle and the occurrence of heart disease and diabetes in elderly population aged 60 years and above in the communities of Xi'an. Multivariate logistic regression was used to analyze the relationship between lifestyle and the risk of heart disease and diabetes. Results A total of 413 elderly people were investigated, of which 31.96% had heart disease, 27.12% had diabetes, and 10.90% had diabetes with heart disease. Multivariate logistic regression analysis revealed that age, BMI, family history, sweet food preference, smoking, and sitting and lying for a long time were risk factors for diabetes in the elderly population (P<0.05). Age, BMI, family history, history of diabetes, preference for salted products, smoking, drinking, and sitting and lying for a long time were risk factors for heart disease in the elderly population (P<0.05). Conclusion The incidence rates of heart disease and diabetes are high in the elderly population in Xi'an City. The risk of diabetes is related to unhealthy lifestyles such as sweet food preference, smoking, and sitting and lying for a long time, while heart disease is related to unhealthy lifestyles such as preference for salted products, smoking, drinking, and sitting and lying for a long time.

Objective To analyze the risk factors and re-intervention strategies for mid- and long-term residual after arterial switch operation (ASO). Methods The clinical data of children with complex congenital heart disease who underwent ASO surgery in Shanghai Children’s Medical Center from January 2006 to June 2022 were retrospectively collected, and the risk factors for mid- and long-term residual after ASO were analyzed. Results A total of 952 children undergoing ASO were enrolled in this study, including 654 males and 298 females with an average age of (102.9±90.1) d and weight of (4.6±1.6) kg. There were 421 patients with D-transposition of the great arteries with intact ventricular septum (D-TGA/IVS), 357 patients with D-transposition of the great arteries with ventricular septal defect (D-TGA/VSD), and 174 patients with right ventricle double outlet combined with subpulmonary ventricular septal defect (Taussig-Bing malformation). Eighty-nine patients died early after the surgery, the mortality rate was 9.3%. The 746 surviving children were regularly followed up after the surgery (follow-up rate 86.4%), with a median follow-up time of 79.4 (12.0-188.0) months. During the follow-up, 53 children underwent surgical re-intervention due to residual, including 33 males and 20 females, with a median age of 62.5 (17.0-214.0) months. The median surgical weight was 19.0 (8.2-86.0) kg, and the mean time of re-intervention was 28.0-170.0 (77.5±45.4) months after the ASO. Residual problems included common trunk and branch stenosis of the pulmonary artery in 23 patients, right ventricular outflow tract (RVOT) obstruction in 11 patients, left ventricular outflow tract obstruction in 6 patients, aortic arch restenosis in 5 patients, aortic insufficiency in 5 patients, residual shunt of ventricular septal defect in 2 patients, and tricuspid valve insufficiency in 1 patient. The early postoperative mortality rate was 3.8% (2/53), with the causes of death being acute myocardial infarction due to coronary artery injury and acute left heart failure, respectively. The mean follow-up time of the surviving children was (52.4±28.6) months, and no mid- and long-term death occurred. Two patients underwent the third operations due to pulmonary restenosis. The multivariate analysis result showed that combined aortic arch surgery and early postoperative RVOT velocity>3 m/s were independent risk factors for mid- and long-term residual after ASO. Conclusion ASO is an ideal procedure for the treatment of D-TGA/IVS, D-TGA/VSD and Taussig-Bing malformations. Combined aortic arch surgery and early postoperative RVOT velocity>3 m/s are independent risk factors for mid- and long-term residual after ASO.

Objective To analyze the clinical efficacy of right midaxillary straight incision surgery in the treatment of doubly committed subarterial ventricular septal defect. Methods The clinical data of children with doubly committed subarterial ventricular septal defect who received surgeries in our hospital from August 2020 to July 2023 were analyzed retrospectively. All the children underwent surgical repair and were divided into two groups according to the incision position, including a right midaxillary straight incision group and a median incision group. The outcomes were compared between the two groups. Results A total of 187 patients were enrolled. There were 102 patients in the right midaxillary straight incision group, including 55 males and 47 females with a median age of 26.0 (5.0, 127.0) months and a median weight of 12.5 (5.1, 32.8) kg at surgery. There were 85 patients in the median incision group, including 37 males and 48 females with a median age of 4.0 (2.0, 168.0) months and a median weight of 6.7 (4.8, 53.9) kg at surgery. No mortality occurred in the study. There was no statistical difference between the two groups in the cardiopulmonary bypass time [(50.0±18.4) min vs. (46.1±15.7) min] or aortic cross-clamping time [(31.3±18.6) min vs. (26.3±17.5) min] (P>0.05). Compared to the median incision group, the time from the end of cardiopulmonary bypass to the closure of chest [(22.3±15.6) min vs. (37.1±13.4) min, P<0.001], postoperative hospital stay [(6.9±3.9) d vs. (8.6±3.6) d, P=0.002], the length of incision [(4.3±2.7) cm vs. (8.5±3.2) cm, P<0.001], drainage volume [(79.0±32.2) mL vs. (100.2±43.1) mL, P<0.001], and the pain score on the 2nd and the 3rd day after the operation were statistically better in the right midaxillary straight incision group (P<0.05). The medical experience and incision satisfaction scores at discharge of the right midaxillary straight incision group were higher (P<0.05). During the follow-up of 21.0 (1.0, 35.0) months, no residual shunt was detected and all patients in both groups had a normal cardiac function and mild or less valve regurgitation. Conclusion Compared to the median incision, minimally invasive right midaxillary straight incision for the repair of doubly committed subarterial ventricular septal defect offers comparable efficacy and reliability, with the added advantages of being minimally invasive, cosmetically superior, and promoting faster postoperative recovery.

Objective To summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). Methods The clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. Results A total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. Conclusion AAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.
