Objective:To investigate the risk factors affecting live birth outcomes in patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) and to establish a predictive model. Methods:A retrospective case-control study was conducted by collecting data from 563 patients with PCOS who were treated at the Reproductive Medicine Department of the General Hospital of Northern Theater Command between June 2018 and January 2023. Patients were divided into live birth ( n=341) and non-live birth ( n=222) groups based on pregnancy outcomes. Univariate and multivariate logistic regression analyses were performed to identify risk factors, followed by construction of a nomogram prediction model based on values with P<0.05 in multiple regression analysis. The model's predictive performance was evaluated using receiver operating characteristic curve analysis, calibration curves, Hosmer-Lemeshow (H-L) goodness-of-fit test, and decision curve analysis. Results:1) Univariate analysis revealed that there were statistically significant differences in age, body mass index (BMI), insulin level, the number of high-quality embryos, and the rate of high-quality embryos between the two groups (all P<0.05). 2) After adjusting for confounding factors, the results of multivariate logistic regression analysis on variables associated with live birth outcomes in the live birth group showed that: age ( OR=1.151, 95% CI: 1.061-1.249, P=0.001), body mass index ( OR=1.141, 95% CI: 1.074-1.214, P<0.001), and insulin level ( OR=1.206, 95% CI: 1.149-1.266, P<0.001) were independent risk factors for live birth outcome; top-quality embryo rate ( OR=0.101, 95% CI: 0.033-0.310, P<0.001) was a protective factor; and the number of top-quality embryos ( OR=0.949, 95% CI: 0.887-1.014, P=0.104) showed no statistically significant association with live birth outcome. 3) A predictive model for the live-birth outcome after IVF/ICSI-ET in PCOS patients was established. The area under the curve (AUC) values for predicting the live-birth outcome based on female age, BMI, the rate of high-quality embryos, and insulin level were 0.581, 0.747, 0.725, and 0.813, respectively. The combined model of these four factors had an AUC value of 0.846 for predicting the live-birth outcome. 4) A nomogram predictive model for the live-birth outcome after IVF/ICSI-ET in PCOS patients was established. The slope of the model's calibration curve was close to 1, and the H-L test yielded a P>0.05, indicating a high consistency between predicted and actual events. The decision analysis curve confirmed the clinical practicality of the predictive model. Conclusion:Age, BMI and insulin level are independent risk factors for live birth outcomes in PCOS patients undergoing IVF/ICSI-ET, while the high-quality embryo rate serves as a protective factor. The established predictive model demonstrates excellent performance and may facilitate clinical decision-making.

Nutrition dietary prescription (NDP) refers to quantified recipes or dietary plans that are developed and implemented by trained physicians, clinical dietitians, or registered dietitians to target the main issues faced by individual chronic disease patients based on nutritional screening, nutritional assessment, diagnosis of malnutrition, and comprehensive evaluation. As an important part of nutritional management of chronic diseases, NDP is recommended to be implemented with exercise prescriptions and traditional Chinese medicine (TCM) food therapies to improve the nutritional status and clinical outcomes of patients with chronic diseases, thereby enhancing their quality of life and reducing medical costs.

Objective:To evaluate the efficacy and safety of spesolimab in the treatment of generalized pustular psoriasis (GPP) .Methods:Six patients with GPP were retrospectively collected from Nanjing Drum Tower Hospital from February 2024 to April 2024, including 2 males and 4 females, aged 16 - 50 years. Four patients had a history of plaque psoriasis. Before treatment, the GPP Area and Severity Index (GPPASI) scores of the patients ranged from 24.6 to 60.8 points, and their GPP Physician Global Assessment (GPPGA) scores ranged from 2 to 4 points. All the 6 patients were intravenously injected with a single dose of 900 mg of spesolimab. Their GPPASI and GPPGA scores were recorded at weeks 1, 4, and 12, and adverse reactions were monitored during the treatment and follow-up.Results:Twenty-four hours after treatment, pustules were markedly reduced in the 6 patients with GPP; at week 1, pustules completely subsided, but erythema persisted; at week 4, both GPPASI and GPPGA scores decreased to 0 points; at week 12, no recurrence was observed. The patients with comorbid hypertension (4 cases), diabetes (1 case), or kidney disease (2 cases) maintained stable pressure or blood glucose levels, or showed improved renal function during the treatment and follow-up. Two patients experienced a transient fever after the treatment with spesolimab, resolving spontaneously after 2 days; two other patients exhibited exacerbation of plaque psoriasis. During the 12-week follow-up, none of the 6 patients experienced serious adverse reactions such as infections.Conclusion:In this study, spesolimab demonstrated rapid-onset efficacy and favorable safety in the treatment of GPP; conventional-dose spesolimab seemed safe for GPP patients with kidney disease.

The production of high-quality oocytes requires precisely orchestrated intercellular communication. Extracellular vesicles (EVs) are cell-derived nanoparticles that play a vital role in the transfer of bioactive molecules, which has gained much attention in the field of diagnosis and treatment. Over the past ten years, the participation of EVs in the reproductive processes of oocytes has been broadly studied and has shown great potential for elucidating the intricacies of female reproductive health. This review provides an extensive discussion of the influence of EVs on oocytes, emphasizing their involvement in normal physiology and altered cargo under pathological conditions. In addition, the positive impact of therapeutic EVs on oocyte quality and their role in alleviating ovarian pathological conditions are summarized.

Objective To investigate the correlation between seminal plasma oxidation-reduction potential(ORP)and normalized ORP(nORP)with sperm DNA fragmentation index(DFI),high DNA staining(HDS),and motility parameters,and to explore whether these parameters can be used as biomarkers for evaluating male fertility potential.Methods A total of 309 men who attended the andrology clinic at the Department of Reproductive Medicine,General Hospital of Northern Theater Command,between October 2023 and December 2023,were selected in this study.We analyzed the correlation between seminal plasma ORP and nORP and parameters such as DFI using the electrode method,HDS,age,days of abstinence,semen volume,total sperm count,sperm concentration,sperm motility(forward motile sperm count,forward motile sperm percentage,non-forward sperm count,non-forward sperm percentage,immotile sperm count,immotile sperm percentage,and sperm motility rate),and motility indices(curvilinear velocity[VCL],straight-line velocity[VSL],average velocity[VAP],linear index[LIN],straightness index[STR],and wobble coefficient[WOB]).The nORP results were divided into three groups and analyzed in relation to each of the parameters mentioned above.A generalized linear regression model was used to assess the relationship between nORP and HDS,with smooth curve fitting performed to visualize this relationship.Results Pearson and Spearman correlation analyses revealed that both ORP and nORP were positively correlated with semen volume,percentage of immotile sperm,and DFI,but negatively correlated with forward motile sperm count,percentage of forward motile sperm,sperm motility rate,VSL,and VAP(P＜0.05).Additionally,ORP was positively correlated with abstinence days and immotile sperm count(P＜0.05)and negatively correlated with LIN,STR,and WOB(P＜0.05).However,nORP was positively correlated with HDS(P＜0.05),and negatively correlated with total sperm count,sperm concentration,non-forward sperm count,non-forward sperm percentage,immotile sperm count,and VCL(P＜0.05).The nORP group showed significant differences in semen volume,total sperm count,sperm concentration,forward motile sperm count,forward motile sperm percentage,non-forward sperm count,non-forward sperm percentage,immotile sperm count,immotile sperm percentage,sperm motility rate,VCL,VSL,VAP,DFI,and HDS(P＜0.05).A smooth curve fitting of nORP and HDS,adjusted for age and abstinence days,demonstrated a linear upward trend in nORP as HDS increased.Conclusion Both ORP and nORP are associated with sperm DFI and key motility parameters.Moreover,nORP is closely related to HDS,which reflects sperm maturity,offering a more comprehensive indicator of semen quality.Thus,nORP can be utilized as a biomarker for assessing male fertility potential.

Objective To investigate the effect and mechanism of melatonin in alleviating hypoxia-induced apoptosis in ovarian gra-nulosa cells.Methods Rat ovarian granulosa cells were isolated and divided into normoxic,hypoxic,and melatonin groups.Hypoxia-induced injury models were established in the hypoxic and melatonin groups,and granulosa cells in the melatonin group were treated with melatonin.A total of 24 rats were randomized into the control,model,and intervention groups(n=8 per group).Rat models of declining ovarian function induced by long-term hypoxia were established in the model and intervention groups.The rats in the intervention group were intraperitoneally injected with melatonin.Cell proliferation was measured using a CCK-8 assay,and lactate secretion and HIF-1αprotein with a specific kit,respectively.The levels of estradiol and progesterone in the cell supernatant and rat serum were detected using ELISA.Granulosa cell apoptosis was detected by flow cytometry,ovarian morphology by HE staining,and Bax and caspase-3 expression by Western blotting.Results Compared with the normoxic group,the hypoxic group exhibited decreased granulosa cell proliferation,increased apoptosis,elevated lactate and HIF-1α levels,and reduced estradiol and progesterone levels(P＜0.05).Compared with hypoxic group,these changes were significantly reversed in the molatonin group(P＜0.05).Compared with the control group,the model group showed increased lactate,HIF-1α,Bax,and caspase-3 levels,decreased estradiol and progesterone levels,and reduced follicles.Compared with the model group,all the indicators were ameliorated in the intervention group(P＜0.05).Conclusion Melatonin alleviated hypoxia-induced granulosa cell apoptosis and promoted the recovery of ovarian function.

Objective To investigate the relationship between high DNA stainability(HDS)and routine semen parameters.Methods Semen samples were collected from 396 men of childbearing age who were admitted to our department.Correlations of HDS with routine semen parameters and age were analyzed.Multiple linear regression analysis was performed to identify the routine semen parameters that had the greatest influence on HDS.The correlation of HDS and DNA fragmentation index(DFI)with routine semen parameters and age in 244 patients with teratozoospermia was analyzed.The 244 patients were divided into extremely severe,severe,moderate,and mild teratozoospermia groups,and differences in HDS,DFI,and routine semen parameters were compared among the four groups.Results HDS was negatively correlated with total sperm count,sperm concentration,sperm progressive motility,and normal sperm morphology rate(NSMR)(P<0.01).After adjusting for potential confounders,including total sperm count,sperm concentration,sperm progressive motility,NSMR,and DFI,NSMR had the most significant negative effect on HDS(P<0.05).In the 244 patients with teratozoospermia,HDS was negatively correlated with NSMR(P<0.01)and positively correlated with the percentage of sperm head and tail abnormalities(P<0.05),while DFI was positively correlated with the percentage of sperm tail abnormalities(P<0.01).There was a significant difference in the percentage of sperm head abnormalities among the four teratozoospermia groups.The more severe the malfor-mation,the higher the percentage of sperm head abnormalities was(P<0.001).HDS in the extremely severe teratozoospermia group was significantly higher than that in the mild and moderate teratozoospermia groups(P<0.05).No significant differences in DFI were found among the four groups(P>0.05).Conclusion HDS was closely correlated with routine semen parameters and was a crucial biomarker for assessing sperm quality,particularly the extent of sperm head abnormalities.
