Objective To investigate the relationships of serum levels of Xenin-25 and activin A with pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods A total of 269 pregnant women with GDM admitted to our hospital between December 2020 and February 2023 were enrolled.Serum levels of Xenin-25 and activin A were measured,and pregnancy outcomes were recorded.Based on pregnancy outcomes,patients were divided into poor pregnancy outcome group(91 cases)and good pregnancy outcome group(178 cases).The influencing factors of adverse preg-nancy outcomes of GDM patients and the predictive value of Xenin-25 and activin A for GDM preg-nancy outcomes were analyzed.Results The poor pregnancy outcome group had higher age,pre-pregnancy body mass index(BMI),proportion of adverse obstetric history,as well as levels of fasting plasma glucose(FPG),glycated hemoglobin(HbA1c),and activin A compared to the good preg-nancy outcome group,and serum level of Xenin-25 was lower in the poor pregnancy outcome group(P＜0.05).High HbA1c and high activin A levels were identified as risk factors for pregnancy out-comes in GDM patients,while high Xenin-25 was a protective factor for pregnancy outcomes(P＜0.05).The areas under the curve(AUCs)for predicting adverse pregnancy outcomes in GDM pa-tients using Xenin-25 and activin A were 0.895 and 0.865,respectively,while the AUC for com-bined prediction was 0.981,which was higher than that of Xenin-25 or activin A alone(P＜0.05).Conclusion Xenin-25 and activin A in GDM patients are associated with adverse pregnancy outcomes and can serve as biomarkers for predicting pregnancy outcomes.

Objective To investigate the interpersonal disturbances and its related factors among college students.Methods The field questionnaire survey was conducted among 730 college students with stratified-cluster sampling method in Zhengzhou University.The self-administered anonymous survey instruments included the Interpersonal Relationships Integrated Diagnosis Questionnaire,Parental Bonding Instrument questionnaire,Self-Rating Anxiety Scale and Pittsburgh Sleep Quality Index.Results ①Detection rate of interpersonal relationship disturbance was 47.8％ in 730 college students.Severe interpersonal disturbances accounted for 16.3％.The most serious problem was communication and making friends disturbance which accounted for 58.5％ of the total.②)There were statistical differences of conversation scores ((2.15± 1.66),(2.53± 1.83),(2.22± 1.79)) among different major college students (medical,engineering,liberal arts) (P＜0.05).A statistical difference was found in making friends((2.76±1.89),(3.18± 1.92)) and getting along with opposite gender ((2.23 ± 1.82),(1.81 ± 1.66)) between male and female (P＜ 0.05).There were significant differences of conversation ((2.58 ± 1.84),(2.02 ± 1.65)),making friends ((3.28 ± 1.93),(2.78 ±1.88)) and getting along with opposite gender ((2.16± 1.75),(1.77± 1.69)) between grade one and three students(P＜0.05).③The interpersonal disturbances were significantly related to parental bonding styles,anxiety and sleep quality.④The results of logistic regression showed that anxiety was the main risk factor (B =1.42,OR=4.4,95％ CI =1.74-9.86,P＜0.01) and maternal parenting style and sleep quality were protective factors(P＜0.01)of interpersonal disturbances.Conclusion The interpersonal disturbance,which are severe and affected by multiple factors in college students,should be paid attention by school,society and family to improve their learning and growing environment in order to promote their physical and mental health.
