Objective To investigate the effect of surgical intervention on IVF/ICSI assisted conception outcomes in patients with ovarian endometriosis(OEM).Methods OEM patients who underwent IVF/ICSI treat-ment at the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University between January 1,2019 and February 1,2024 were selected,including 228 cases in the non-operated group before assisted conception(Group A)and 426 cases in the operated group before assisted conception(Group B),and the assisted concep-tion outcomes of the two groups were analysed.Results There were no statistically significant differences in female age,BMI,infertility years,infertility type,and basal FSH level between the two groups(P＞0.05).AMH level and basal AFC were higher in group A than in group B(P=0.003).There was no statistical difference in the application of ovulation induction programme,total number of Gn days and total amount of Gn between the two groups(P＞0.05),but the amount of Gn initiation in Group A was lower than that in Group B(P=0.011).Applying multiple linear regression to adjust for confounding factors,there was a statistical difference in the 2PN fertilization rate between Groups A and B(P=0.007),whereas there was no statistical difference in the number of eggs obtained,the rate of available embryos,the rate of high-quality embryos and the rate of blastocyst formation between the two groups(P＞0.05).After applying binary logistic regression to adjust for the influencing factors related to clinical pregnancy rate and live birth rate,the clinical pregnancy rate(aOR=-0.896,95％CI:0.540～1.488),live birth rate in the two groups(aOR=0.976,95％CI:0.589～1.620)remained statistically indistin-guishable.Conclusions Surgical intervention may further impair ovarian reserve function in patients with OEM,but does not appear to affect embryo quality or pregnancy outcome.Surgical treatment prior to assisted conception may improve fertilization rates in patients with OEM.

Objective To exploring the effect of inflammatory indicators on the outcome of assisted conception of in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)in patients with ovarian endometriosis(OEM).Methods The study subjects were selected as the patients with OEM who received IVF/ICSI treatment at the Third Affiliated Hospital of Zhengzhou University from January 2019 to February 2024.Based on whether previous surgery for uterine endometriosis cyst removal had been performed,they were divided into non-surgery group(n=73)and surgery group(n=112).To explore the differences in inflammatory markers between two groups and to determine whether they have an impact on the outcome of assisted reproduction.Results The lymphocytes(L)and blastocyst formation rates of patients in surgery group were significantly higher than those in non-surgery group,platelet to lymphocyte ratio(PLR)and carbohydrate antigen 125(CA125)were significantly lower than those in non-surgery group(P＜0.05).There were no statistically significant differences in the clinical pregnancy rate and live birth rate between two groups of patients(P＞0.05).After adjusting for confounding factors,the results of multivariate Logistic regression analysis showed that L,PLR,and CA125 had no statistically significant impact on the clinical pregnancy rate and live birth rate(P＞0.05).Both maternal age and the number of embryos transferred exerted a certain influence on clinical pregnancy rates and live birth rates(P＜0.05),furthermore,the type of embryo transferred had a significant effect on clinical pregnancy rates(P＜0.05).Conclusion Compared with non-surgery group,surgery group had higher L level and lower PRL and CA125 levels,but these changes did not significantly affect clinical pregnancy or live birth outcomes in OEM patients undergoing IVF/ICSI assisted reproduction.

Objective:To establish a framework of entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology, standardize the training process, and provide an effective evaluation method.Methods:Based on literature review and discussions, a preliminary expert consultation questionnaire was developed. From July to November 2024, a modified Delphi method was adopted and relevant experts were invited to assess the importance, validity, and feasibility of each indicator using a 5-point Likert scale. The results were used to screen and refine the entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology.Results:In the two rounds of expert consultation, the valid questionnaire return rate reached 100.00%, with an expert judgment basis coefficient of 0.73 and a familiarity coefficient of 0.90. Based on expert feedback, the final framework retained 3 first-level indicators and 12 second-level indicators. Modifications included renaming "Anesthesia Management" to "Anesthetic Drug Management", swapping the order of "Intraoperative Emergency Management" and "Airway Management", and removing the indicator "Resuscitation Assessment".Conclusions:This study preliminarily developed a framework of entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology. The framework provides a simple and practical competency evaluation method for standardized training, which can enhance training quality and effectiveness.

This study analyzed the clinical and laboratory data of 3 children diagnosed with mitochondrial disease-associated primary adrenal insufficiency (PAI) at the Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from October 2018 to November 2023.All patients were normal at birth but gradually developed symptoms and were diagnosed with PAI between the ages of 1 year and 1 month and 7 years and 3 months.The children presented typical clinical symptoms of PAI, including skin and mucosal hyperpigmentation (3 cases), electrolyte disturbances (3 cases), and hypoglycemia (2 cases), as well as multisystem abnormalities related to mitochondrial disease, including recurrent infections, growth retardation, cachexia, and hyperlactatemia.Genetic testing revealed significant single deletions in mitochondrial DNA in all patients: Patient 1: m.11219_15954del, Patient 2: m.8483_13459del, and Patient 3: m.8649_16084del.Treatment with Hydrocortisone acetate replacement therapy improved the electrolyte disturbances and hypoglycemia, but issues with recurrent infections, growth retardation, and cachexia persisted.This study suggests that in clinical practice, the possibility of mitochondrial disease should be highly suspected when PAI patients present with multisystem abnormalities, especially in conjunction with hyperlactatemia.

BACKGROUND:Studies have shown that cardiomyocyte apoptosis is closely related to cardiac decompensation and the cardiac aging process.Appropriate exercise can alter heart pump function in patients with heart failure as well as attenuate aging-induced cardiomyocyte apoptosis,hypertrophy,and fibrotic damage. OBJECTIVE:To investigate the effects of long-term aerobic exercise on cardiomyocyte apoptosis and the thioredoxin system in aging rats. METHODS:Thirty-six male Sprague-Dawley rats were selected and divided into three age groups:3-month-old young group,9-month-old middle-aged group,and 18-month-old elderly group,with 12 rats in each group.Within each age group,rats were randomly assigned to sedentary and exercise subgroups(n=6 per group).The sedentary groups did not undergo any exercise intervention.The exercise groups were acclimated to a treadmill environment and subsequently subjected to treadmill exercise for 45 minutes per day,at a speed of 15 m/min,5 days per week for 10 weeks in total.At 24 hours after the final intervention,ELISA was employed to measure serum levels of cardiac troponin I and creatine kinase-MB in rats.TUNEL assay was utilized to detect cardiomyocyte apoptosis,while western blot assay was employed to assess the protein expression of Bax,Bcl-2,Caspase 3,thioredoxin-1,thioredoxin-2,thioredoxin reductase-1,thioredoxin reductase-2,thioredoxin-interacting protein,apoptosis signal-regulating kinase 1,and P38 mitogen-activated protein kinase in rat myocardial tissue. RESULTS AND CONCLUSION:Serum levels of cardiac troponin I and creatine kinase-MB in the elderly sedentary group were significantly higher than those in the young and middle-aged sedentary groups and elderly exercise group(P<0.01).Serum levels of cardiac troponin I and creatine kinase-MB in the elderly sedentary group were significantly higher than those in the young and middle-aged exercise groups and elderly exercise group(P<0.01).Positive apoptotic cells in rat myocardial tissue,along with increased protein expression of Bax and Caspase 3,exhibited an age-related upward trend,while Bcl-2 protein expression showed a declining trend.In comparison with the sedentary groups within each age category,the number of apoptotic cardiomyocytes and the expression of Bax and Caspase 3 proteins were reduced to different degrees,and the expression of Bcl-2 protein was increased to different degrees in the corresponding exercise groups.Compared with the young sedentary group,middle-aged sedentary group and elderly exercise group,elderly sedentary rats showed a significant decrease in the expression of myocardial thioredoxin 1,thioredoxin 2,thioredoxin reductase 1,and thioredoxin reductase 2 proteins(P<0.05,P<0.01).The expression of myocardial thioredoxin 1,thioredoxin 2,and thioredoxin reductase 2 proteins was lower in the elderly exercise group than in the young exercise group(P<0.05,P<0.01),while the expression of thioredoxin reductase 1 and thioredoxin reductase 2 proteins was lower in the elderly exercise group than in the middle-aged exercise group(P<0.01).The protein expression of thioredoxin-interacting protein,apoptosis signal-regulating kinase 1,and P38 mitogen-activated protein kinase in rat myocardium was significantly higher in the elderly sedentary group than the young sedentary group,middle-aged sedentary group and elderly exercise group(P<0.01).The protein expression of thioredoxin-interacting protein,apoptosis signal-regulating kinase 1,and P38 mitogen-activated protein kinase in rat myocardium was significantly higher in the elderly exercise group than the young exercise group and middle-aged exercise group(P<0.01).To conclude,aerobic exercise may enhance the anti-apoptotic effects of thioredoxin by down-regulating the expression of thioredoxin-interacting protein in aging rat hearts,leading to the downregulation of apoptosis signal-regulated kinase 1 and P38 mitogen-activated kinase protein,thereby alleviating myocardial cell apoptosis in aging rat hearts.

Objective To investigate the clinical manifestations,molecular genetics and gonadal pathol-ogy characteristics of patients with disorders of sex development(DSD),and to summarize the clinical experi-ence of identifying rare diseases from common symptoms.Methods The clinical data of 416 patients with DSD diagnosed and treated in the multidisciplinary center of DSD of Guangzhou Women and Children's Medical Cen-ter from May 2018 to August 2023 were retrospectively analyzed,summarized and discussed.Results Accord-ing to chromosome karyotype,416 cases of DSD were classified into three types:92 cases(22.1％)of abnormal sex chromosome karyotype,285 cases(68.5％)of 46,XY karyotype and 39 cases(9.4％)of 46,XX karyotype.Among the 92 patients with abnormal sex chromosome karyotype,59 cases were raised as males,18 cases(30.5％)complained of short penis with hypospadias and cryptorchidism.The most common karyotype was 45,X/46,XY(58 cases,63.0％).Among the 285 patients with 46,XY karyotype,238 cases were raised as males,and 63 cases(26.5％)complained of short penis and hypospadias;47 cases were raised as females,and 13 ca-ses(27.7％)complained of inguinal mass.A total of 216 patients with 46,XY karyotype were subjected to whole exome gene detection,and 155 cases(71.8％)were found to have molecular pathogenesis with the clinical phe-notype.Among the 39 patients with 46,XX karyotype,19 cases were raised as males,and 8 cases(42.1％)com-plained of short penis and hypospadias.In the 18 cases of gonad biopsy,17 cases showed testicular tissue in go-nads.Whole exome sequencing was performed in 14 cases.NR5A1 gene heterozygous mutation,SRY gene muta-tion and SOX3 gene mutation were found in 2 cases,respectively(14.3％).Twenty cases were raised as females,and 14 cases(70.0％)complained of clitoral hypertrophy.Gonad biopsy was performed in 8 cases,with 7 cases of ovotestis(87.5％)and 1 case of NR5A1 gene heterozygous mutation(14.3％).Conclusions The etiologies of DSD are complex and diverse,and the clinical manifestations are various,which can be manifested as hypospa-dias,micropenis,cryptorchidism and other common symptoms of the urinary system.Different etiologies have dif-ferent treatment options.Therefore,chromosome karyotype,molecular genetic testing and gonadal pathology can be used to clarify the cause of disease,especially for rare diseases,improve the detection rate,reduce the rate of missed diagnosis,and ensure reasonable treatment,especially sex selection.
