Objective:To investigate the status of allostatic load (AL) in patients with polycystic ovary syndrome (PCOS) and its influence on the clinical outcomes of in vitro fertilization-embryo transfer.Methods:This was a prospective study. By using convenient sampling method, 421 patients with PCOS (PCOS group) and 372 control infertility patients (control group) in the Reproductive Center of the First Affiliated Hospital of Anhui Medical University from April 2022 to January 2024 were investigated for basic information, physical examination, laboratory examination and follow-up of clinical outcomes. The total score of AL was calculated using 16 related indicators of cardiovascular system, metabolic system and immune system, and AL>3 was used as the judgment criteria for the high level AL group and the low level AL group. The differences in general data, embryo development and clinical outcomes between the groups were compared.Results:There were 222 cases (52.7%, 222/421) in PCOS low level AL group and 199 cases (47.3%, 199/421) in PCOS high level AL group. There were 214 patients (57.5%, 214/372) in the control low level AL group and 158 patients (42.5%, 158/372) in the control high level AL group. Embryo development outcomes: number of oocytes retrieved (median: 12, 12, 19, 14, respectively; P<0.001), number of two pronuclei (median: 8, 7, 11, 8, respectively; P<0.001), number of fertilization (median: 9, 9, 13, 10, respectively; P<0.001), number of metaphase of meiosis Ⅱ oocytes (median: 9, 8, 13, 10, respectively; P<0.001), number of transferable embryos (median: 5, 5, 7, 6, respectively; P<0.001), number of high-quality embryos (median: 4, 3, 6, 5, respectively; P<0.001), gonadotropin(Gn) starting dosage (median: 150, 200, 150, 200 U, respectively; P<0.001), total dosage of Gn (median: 1 800, 2 075, 1 575, 2 025 U, respectively; P<0.001), duration of Gn used (median: 10, 10, 10, 10 days, respectively; P=0.027) in the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group were significantly different. Pairings between groups showed that number of oocytes retrieved, number of two pronuclei, number of fertilization, number of metaphase of meiosis Ⅱ oocytes and number of transferable embryos in PCOS high level AL group were lower than those in PCOS low level AL group (all P<0.05); Gn starting dosage and total dosage of Gn in PCOS low level AL group were lower than those in the other three groups (all P<0.05); duration of Gn used in PCOS high level AL group was higher than that PCOS low level AL group ( P<0.05). Clinical outcomes: the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group underwent fresh transplantation [27.4% (57/208), 24.4% (38/156), 15.1% (32/212), 17.1% (33/193), respectively; P=0.006] and the proportion of transplanted day 5 embryos [82.7% (172/208), 77.6% (121/156), 91.0% (193/212), 86.5% (167/193), respectively; P=0.018] were statistically significant. There were no significant differences in fertilization rate, biochemical pregnancy rate, clinical pregnancy rate, multiple pregnancy rate and early abortion rate among the four groups (all P>0.05). Conclusion:The high level of AL in PCOS patients may affect the outcomes of embryo development, and more attention should be paid to AL in PCOS patients to reduce stress.

Objective To develop and evaluate dietary and exercise intervention program for over-weight/obese patients with polycystic ovary syndrome(PCOS).Methods Seventy patients with over-weight/obese PCOS were prospectively selected as research subjects and divided into intervention group(n=35)and control group(n=35)according to random number table method.According to the completion of the intervention plan,29 cases were finally included in the intervention group and 28 cases in the control group.The control group was given conventional nursing intervention,while the intervention group was applied with the diet and exercise intervention program for overweight/obese patients with PCOS.Both groups were intervened for 3 months.The physical indicators,PCOS sign scores,natural pregnancy rate,degree of self-body image distress(Multidimensional Self-body Im-age Relationship Questionnaire-Appearance Subscale)and self-efficacy level(Self-efficacy Scale)before and after the intervention were compared between the two groups.The occurrence of adverse reactions during the intervention period between the two groups were compared.Results After 1 month and 3 months of intervention,the body mass index(BMI)and PC OS sign score of the pa-tients in the intervention group were significantly lower than those in the control group(P＜0.05).The natural conception rate of the intervention group was 34.48％(10/29),which was significantly higher than 10.71％(3/28)of the control group(P＜0.05).After 1 month and 3 months of inter-vention,the scores of the self-body image relationship-appearance subscale of the patients in the inter-vention group were significantly higher than those in the control group(P＜0.001).After 3 months of intervention,the score of the Self-efficacy Scale of patients in the intervention group was significantly higher than that in the control group(P＜0.001).During the intervention period,no adverse reac-tions caused by diet and exercise intervention occurred in either group.Conclusion Implementing a diet and exercise intervention program for overweight/obese patients with PCOS is beneficial for re-ducing patients' BMI,increasing the natural pregnancy rate,improving self-body image disorders,and enhancing self-efficacy.

Polycystic ovary syndrome (PCOS) is a common chronic disease in women of childbearing age, which mainly threatens women's reproductive health and metabolism. Globally, 5%-20% of women of childbearing age are affected, depending on the diagnostic criteria. There is currently no effective treatment, so early and long-term management is crucial. International evidence-based guidelines for the assessment and management of PCOS recommend lifestyle interventions, such as exercise alone or a variety of diets combined with exercise and behavioral strategies, as first-line management options for women with PCOS to improve metabolic health. This review summarizes the new progress in the application of lifestyle interventions in PCOS patients from different dietary patterns, exercise interventions and action management in order to improve the attention of medical staff in China to the female population of PCOS and provide technical reference for the future application in the health management practice of PCOS patients.

Objective:To explore the association of gait speed and cognitive function of the community-dwelling elderly.Methods:From March to December 2021, a total of 1 172 Xinxiang community-dwelling elderly people were investigated by general information questionnaire, mini-mental state examination(MMSE), patient health questionnaire depression scale and 4.6 m gait test. The elderly were divided into five groups based on the quintile grouping of gait speed values, with Q1 group (≤0.76 m/s), Q2 group (0.77-0.88 m/s), Q3 group (0.89-0.98 m/s), Q4 group (0.99-1.11 m/s) and Q5 group (≥1.12 m/s). SPSS 25.0 statistical software was used for descriptive statistics, and binary Logistic regression was used to analyze the influence of gait speed and depression on cognitive impairment of the elderly.Results:The gait speed of community-dwelling elderly people was (0.92±0.22) m/s. The scores of MMSE in Q1-Q5 groups were (24.72±3.67), (26.63±2.90), (26.58±2.66), (27.01±2.45) and (27.18±2.35), respectively, and the cognitive function was significantly different among the five gait speed groups( F=27.92, P<0.05). The results of binary Logistics regression showed that compared with Q1 group, the OR value (95% CI) of cognitive impairment in Q2-Q5 group were 0.475 (0.253-0.893), 0.426 (0.219-0.828), 0.421(0.212-0.826) and 0.371(0.179-0.766), respectively, which indicated that fast walking speed was a protective factor for cognitive function. Old age ( OR=1.096, 95% CI=1.053-1.140) and depression ( OR=14.441, 95% CI=12.670-19.829) were risk factors of cognitive impairment. Conclusion:The gait speed is associated with cognitive function among community-dwelling elderly people, and faster gait speed is a protective factor for cognitive function.

Objective:To exlplore the association between the baseline luteinizing hormone/follicle stimulating hormone (LH/FSH) ratio of polycystic ovary syndrome (PCOS) and in vitro fertilisation-embryo transfer outcomes.Methods:This was a retrospective cohort study. A total of 2 868 PCOS patients were enrolled, all of the participants were patients in The First Affiliated Hospital of Anhui Medical University Hospital from October 2015 to October 2021. Propensity score matching (1∶2.5) was conducted to regulate the non-random allocation of patients. Data were extracted from the hospital′s medical records. Patients with baseline LH/FSH ratio>2 were deemed as study group, patients with baseline LH/FSH ratio≤2 were deemed as control group. Single factor analysis was applied to compare the differences of pregnancy outcomes between two groups.Results:After propensity score matching (1∶2.5), there were no statistically significant differences in baseline data between the two groups (all P>0.05), indicating that the data were comparable. In the study group, the total dose of gonadotropin (Gn) and duration of Gn were lower than those of the control group ( t=4.989, P<0.001; t=3.267, P=0.001), the rate of in vitro maturation was higher than that of the control group ( χ2=4.938, P=0.026), the number of retrieved oocytes and cleavage were higher than those of the control group ( t=-2.305, P=0.021; t=-2.816, P=0.005), but there were no differences in the number and rate of high-quality embryos between the two groups ( t=-1.636, P=0.102; t=-0.123, P=0.902). The incidence of moderate to severe ovarian hyperstimulation syndrome in the study group was significantly higher than that in the control group ( χ2=17.277, P<0.001). Regardless of fresh embryo transfer or frozen-thawed embryo transfer cycles, the incidences of gestational diabetes mellitus in the study group were higher than those in the control group ( χ2=9.174, P=0.002; χ2=4.204, P=0.040) of singleton pregnancy. In the fresh embryo transfer cycle, the clinical pregnancy rate [30.30% (20/66) vs 47.75% (53/111)] and delivery rate [30.30% (20/66) vs 46.85% (52/111)] in the study group were lower than those in the control group ( χ2=5.198, P=0.023; χ2=4.695, P=0.030). In the frozen-thawed embryo transfer cycle, the delivery rate in the study group was higer than that in the control group [59.41% (423/712) vs 55.04% (1 053/1 913); χ2=7.526, P=0.023]. The clinical pregnancy rate and delivery rate of fresh embryo transfer cycle in the study group were significantly lower than those of frozen-thawed embryo transfer cycle ( χ2=21.308, P<0.001; χ2=20.871, P<0.001), but there were no significant differences in the control group (all P>0.05). Conclusions:PCOS patients with a higher basal LH/FSH ratio are more likely to develop moderate to severe ovarian hyperstimulation syndrome after controlled ovarian stimulation and have a higher incidence of gestational diabetes mellitus. Better pregnancy outcome could be obtained by frozen-thawed embryo transfer.

In recent years, with the in-depth study of pemphigus, new pathogenesis has been identified based on the desmoglein antibody-mediated immune response mechanism, and new progress has been made in targeted therapy. This review summarizes recent advances in the pathogenesis and targeted therapy of pemphigus.

Globally, the prevalence of physical inactivity in the adult population is as high as 27.5%. Physical activity is closely associated with menstrual disorders, ovulation disorders, organic diseases of the reproductive system, and outcomes of reproductive treatment in infertile women, and reasonable and appropriate physical activity is important for preventing and treating female infertility. This paper summarized the studies on the effects of physical activity on the reproductive health of infertile women in recent years by reviewing and analyzing the relevant literature and exploring the possible biological mechanisms to provide a scientific basis for improving the reproductive health of infertile women.

Objective:To explore the relationship among depression, social belonging and fertility quality of life of infertile women, and to provide a theoretical basis for the development of effective measures to improve the quality of life of infertile women.Methods:From July 2022 to October 2022, a random sample of 400 patients treated for infertility in the Reproductive Assisting Centre of the First Hospital of Anhui Medical University were selected using a general basic questionnaire, the Depression Screening Self-Rating Scale (PHQ-9), the Social Attribution Measurement Questionnaire and the Fertility Quality of Life Scale quality of life questionnaire (FertiQoL) were administered. Spearman correlation was used to analyze the association between the variables, and mediating effects were examined by Bootstrap procedure and PROCESS software.Results:The 400 infertile women had a median depression score of 5, reaching a subclinical mild level of depression, a median score of 12 on the social belonging measure, and a median score of 62.87 on the FertiQoL. Social belonging was negatively correlated with depression ( r=-0.206, P<0.001); social belonging was positively correlated with FertiQoL ( r=0.267, P<0.001); and depression was negatively correlated with FertiQoL ( r=-0.428, P<0.001). Mediation analysis showed that after controlling for relevant variables, the indirect effect of depression on FertiQoL in infertile women was -0.069 0 (95% CI: -0.173 3--0.008 3), and the direct effect was -1.019 1 (95% CI: -1.436 3- -0.601 8), the mediating effect of FertiQoL through social belonging on depression in infertile women accounted for 6.34% of the total effect. Conclusion:Social belonging plays a partial mediating role in depression and FertiQoL among infertile women. Infertile women should be given timely attention to their psychological situation and given more social recognition and support to improve their FertiQoL.
