OBJECTIVE To investigate the clinical effectiveness of triptorelin combined with Biejiajian pill in the treatment of adenomyosis （AM）. METHODS Totally 186 patients with AM admitted to Nanyang First People’s Hospital from January 2022 to October 2024 were selected as subjects and randomized into control group （n＝93） and observation group （n＝93） using the random number table method. Patients in the control group received subcutaneous injections of triptorelin acetate around the umbilicus. In addition to the treatment of control group， patients in the observation group orally administered Biejiajian pill. Both groups underwent treatment for 12 weeks and were followed up for 6 months post-treatment. The clinical efficacy， recurrence and the occurrence of adverse drug reactions were compared between the two groups. Traditional Chinese medicine （TCM） symptoms， endometrial receptivity indicators （endometrial thickness， uterine volume， endometrial resistance index and vascular index）， laboratory indexes （serum luteinizing hormone， follicle stimulating hormone， estradiol， carbohydrate antigen 125， insulin-like growth factor-1， and matrix metalloproteinase 9） were compared between the two groups before and after treatment. RESULTS A total of 164 patients completed the treatment and follow-up， among whom 80 cases were in control group and 84 cases in the observation group. The overall effective rate in the observation group was significantly higher than that in the control group， while the incidence of low estrogen levels and recurrence rate were significantly lower in the observation group compared to the control group （P＜0.05）. There were no statistically significant differences in the incidence of nausea or abnormal liver and kidney function between the two groups （P＞0.05）. After treatment， the pain Visual Analogue Scale scores， Pictorial Blood Loss Assessment Chart， TCM symptoms scores， endometrial thickness， uterine volume， endometrial resistance index， and laboratory indicators in both groups were significantly lower than those before treatment within the same group （P＜0.05）. Moreover， these values were significantly lower in the observation group compared to the control group （except for follicle stimulating hormone） （P＜0.05）. The endometrial vascular index of the two groups was significantly higher than that in the same group before treatment， and the observation group was significantly higher than the control group （P＜0.05）. CONCLUSIONS Triptorelin combined with Biejiajian pill has a definite therapeutic effect on AM， which can effectively improve the degree of dysmenorrhea and menstrual flow， improve endometrial receptivity， lower the recurrence rate in patients， and demonstrate good safety.

Objective: To explore the relationship between socio ecological risk factors (SERF), physical activity (PA) developmental trajectories, and depressive symptoms among junior and senior high school students in Tianjin, in order to provide theoretical support for comprehensive interventions for adolescent depression. Methods: A longitudinal follow up design was adopted. In September 2022, a baseline survey was conducted using a stratified cluster random sampling method in two junior high schools and two senior high schools in Tianjin, collecting data on students basic information, SERF, PA, and depressive symptoms. Two follow up surveys were conducted in September 2023 and 2024, yielding 588 valid participants. Latent class growth analysis (LCGA) was used to identify PA developmental trajectory categories among junior and senior high school students. Logistic regression was applied to examine the associations between depressive symptoms and SERF as well as PA trajectories. Results: The detection rates of depressive symptoms among Tianjin junior and senior high school students over the three years were 26.53%, 20.24%, and 21.26 %, respectively. Depressive symptoms were positively correlated with SERF ( OR=1.04, 95%CI=1.03-1.05, P <0.05). The highest risks were observed in the individual dimension and family dimension ( OR =1.28, 1.21, both P <0.05). LCGA identified three PA trajectory groups:persistently low level (80.65%), persistently high level (4.58%), and slowly increasing group ( 14.77 %). Multivariate regression analysis showed that compared with the persistently low level PA, the slowly increasing PA significantly reduced the risk of depressive symptoms ( OR=0.44, 95%CI =0.20-0.88), while SERF still increased the risk of depressive symptoms ( OR=1.04, 95%CI =1.03-1.05) (both P <0.05). Conclusion SERF are risk factors for depression symptoms among junior and senior high school students, whereas slowly increasing PA development trajectory demonstrates a protective effect.

OBJECTIVE To observe the clinical efficacy， safety and recurrence of Kuntai capsules combined with Estradiol tablets/Estradiol dydrogesterone tablets in the treatment of diminished ovarian reserve （DOR） as well as their effects on ovarian reserve function， sex hormones， and lymphocyte subsets. METHODS A retrospective analysis was conducted on the clinical data of 165 DOR patients in Nanyang First People’s Hospital. Among them， 80 patients who received Estradiol tablets/Estradiol dydrogesterone tablets （take one tablet per day according to the medication sequence on the instruction） were included in the control group， while 85 patients who additionally took Kuntai capsules （2.0 g per dose， three times daily） were included in the observation group. The treatment duration for both groups was three months. Clinical efficacy， the incidence of adverse drug reaction （ADR）， recurrence rate， and changes in Traditional Chinese Medicine （TCM） syndrome scores， ovarian reserve function indicators [anti-Müllerian hormone （AMH）， inhibin B （INHB）， antral follicle count （AFC）， endometrial thickness， and ovarian volume]， sex hormones [follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E2）]， and T lymphocyte subsets （CD3 +， CD4 +， CD8 +， and CD4 +/CD8 +） were compared before and after treatment. RESULTS The cure and significant improvement rate in the observation group was significantly higher than in the control group （82.35% vs. 65.00%， P＜0.05）. Compared to baseline levels， both groups showed significant reductions in TCM syndrome scores， FSH， LH， CD3+ and CD8+ levels after treatment， while AMH， INHB， E2， CD4 +， CD4 +/CD8 +， AFC， endometrial thickness， and ovarian volume significantly increased （P＜0.05）. The degree of improvement in these indicators was significantly greater in the observation group than in the control group （P＜0.05）. There was no significant difference in the total incidence of ADR between the two groups（P＞ 0.05）. However， the recurrence rate within six months post-treatment was significantly lower in the observation group compared to the control group （5.88% vs. 21.25%， P＜0.05）. CONCLUSIONS Kuntai capsules combined with Estradiol tablets/ Estradiol dydrogesterone tablets have a significant therapeutic effect on DOR， which can improve ovarian reserve function of the patient， regulate sex hormone levels and T lymphocyte subsets， and reduce recurrence rates， with a high safety profile.

Objective: To investigate the distribution of pupil diameter and its association with myopia in school age children, providing ideas into the mechanisms of the role of pupil diameter in the onset and development of myopia. Methods: Adopting a combination of stratified cluster random sampling and convenience sampling method, 3 839 children from six schools in Shandong Province were included in September 2021. Pupil diameters distribution was analyzed by age, sex, and myopic status. Pearson correlation analysis was used to assess the relationship between pupil diameter and cycloplegic spherical equivalent (SE), as well as axial length (AL) and other variables. Propensity score matching (PSM) was applied to match myopic and non myopic children at a 1∶1 ratio based on age and sex. A generalized linear model (GLM) was constructed with pupil diameter as the dependent variable to identify independent factors influencing pupil size and its association with myopia. Results: The mean pupil diameter of school age children was (5.77±0.80)mm. Pupil diameter exhibited a significant increasing trend with age ( F =49.34， P trend ＜ 0.01). Myopic children had a significantly larger mean pupil diameter [(6.10±0.73)mm] compared to non myopic children [(5.62±0.79)mm] with a statistically significant difference( t=18.10, P <0.01). Multivariable GLM analysis, adjusted for age, amplitude of accommodation, and uncorrected visual acuity, revealed a negative correlation between pupil diameter and cycloplegic SE (before PSM: β =-0.089, after PSM: β =-0.063, both P ＜0.01). Conclusions Myopic school age children exhibite larger pupil diameters than their non myopic counterparts. Pupil diameter may serve as a potential indicator for monitoring myopia development in school age children.

Objective:To understand the occurrence of different patterns of multimorbidity among children and adolescents aged 9-18 in Tianjin City and analyze the cumulative effects of lifestyle on these patterns of multimorbidity.Methods:From September to November 2022, a stratified cluster random sampling method was used to select students from primary schools, junior high schools, general high schools, and vocational schools in 16 districts of Tianjin to screen for height, weight, blood pressure, distant vision, and diopter. One year later, a follow-up measurement and questionnaire survey were conducted. The log-binomial model was used to analyze the strength of the association between lifestyle factors and different patterns of multimorbidity.Results:The age of 9 488 students was (12.37±2.49) years old, including 4 999 boys and 4 489 girls. The detection rates of three patterns of multimorbidity of overweight obesity and high blood pressure, overweight obesity and myopia, and overweight obesity with high blood pressure and myopia were 6.63%, 9.32%, and 4.21%, respectively. The detection rates of the three types of multimorbidity in boys were higher than those in girls (all P<0.001). The detection rate of overweight obesity and high blood pressure in suburban areas was higher than that in urban areas ( P=0.002). The detection rate of overweight obesity and myopia in suburban areas was lower than that in urban areas ( P=0.034). The detection rate of overweight obesity and myopia among those aged 9-12 years old was higher than other age groups (all P<0.001). The ARR (95% CI) for the association between favorable physical activity and the occurrence of overweight obesity and high blood pressure was 0.79 (0.68-0.92). The ARR (95% CI) for the association between favorable physical activity and the occurrence of overweight obesity with high blood pressure and myopia was 0.82 (0.67-0.99). Compared with children and adolescents with 0-2 favorable lifestyle factors, those with 4-5 favorable lifestyle factors had a lower risk of overweight obesity and high blood pressure ( ARR=0.84, 95% CI: 0.59-0.92). Conclusion:Boys aged 9-18 in Tianjin City are more prone to multimorbidity of overweight obesity and high blood pressure, overweight obesity and myopia, and overweight obesity with high blood pressure and myopia. Children and adolescents with 4-5 favorable lifestyle factors have a reduced risk of occurrence of overweight obesity and high blood pressure. Lifestyle has cumulative effects on multimorbidity of overweight obesity and high blood pressure.

Objective:To analyze the correlation between near work, screen time, outdoor time and myopia in children based on objective monitoring technology and to explore the influencing factors related to myopia in children.Methods:A cross-sectional study was conducted.From October 2022 to March 2023, the purposive sampling method was used to select 596 children in Grade 2 and Grade 3 from two primary schools in Shandong Province as study subjects.Eye-Monitor technology of eye-use behavior based on artificial intelligence was used to quantify parameters of near work, screen time and outdoor time.The eye-use behavior parameters were compared within each subject and between non-myopic and myopic children on weekdays and weekends.A multivariate binary logistic regression model was constructed to analyze the influencing factors related to myopia.The study protocol was approved by the Medical Ethics Committee of the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine (No.HEC-HY-2022023KY).Written informed consent was obtained from the legal guardian of each subject.Results:For each subject, the proportion of near work time on weekdays was greater than on weekends, the proportion of time spent looking at cell phones, computer screens, and outdoor activities was smaller, the duration of single continuous near eye use was longer, the tilt angle of the head in sitting position was greater, and the light intensity was stronger, showing statistically significant differences ( t=19.427, -9.964, -5.916, -10.470, 2.211, 2.898, 15.061; all P<0.05).During weekdays, compared with the non-myopia group, the myopia group had longer total near work duration, longer single continuous near eye use duration, shorter outdoor activity duration, closer eye use distance, larger proportion of near work time, and smaller proportion of outdoor activity time, showing statistically significant differences (all P<0.05).During weekends, compared with the non-myopia group, the myopia group had longer time spent looking at cell phones and computer screens, shorter outdoor activity time, greater proportion of time spent looking at cell phones and computer screens, and smaller proportion of outdoor activity time, with statistically significant differences (all P<0.05).During weekdays, after adjusting for confounding factors, longer single continuous near eye use duration ( OR=1.138, 95% CI: 1.086-1.192, P<0.001) was the risk factor for myopia, and longer working distance ( OR=0.906, 95% CI: 0.847-0.970, P=0.004) and longer outdoor activity time ( OR=0.127, 95% CI: 0.023-0.703, P=0.018) were protective factors for myopia.During weekends, after adjusting for confounding factors, longer time spent on looking at cell phone screens ( OR=2.437, 95% CI: 1.460-4.068, P<0.001) and longer time spent on looking at computer screens ( OR=2.260, 95% CI: 1.283-3.979, P=0.005) were risk factors for myopia, and longer outdoor activity time ( OR=0.624, 95% CI: 0.416-0.934, P=0.022) was the protective factor for myopia. Conclusions:The eyes with continuous near work, prolonged use of smartphone and computer screens, closer eye use distance, and less time spent outdoors have been confirmed to be significantly correlated with myopia based on objective monitoring data.When formulating intervention measures for myopia prevention and control in children, it is advocated to further pay attention to control the distance and duration of near work on weekdays and strengthen screen time management on weekends.
