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 investigate the expressions of extracellular matrix metalloproteinase inducer(EMMPRIN),matrix metalloproteinase-9(MMP-9),lysine demethylase 6B(KDM6B)proteins and their correlation with clinicopathologic features in invasive breast cancer,and analyze the correlation among the three proteins and their value in pathological diagnosis of invasive breast cancer.Methods The surgical biopsy specimens of 124 patients with invasive breast cancer who were admitted to the Department of Pathology,the Fifth Clinical Medical College of Henan University of Chinese Medicine/People's Hospital of Zhengzhou from January 2014 to December 2017 were selected as research subjects,and 20 low-grade intraductal carcinoma tissue specimens,27 high-grade intraductal carcinoma tissue specimens,and 22 adjacent tissue specimens＞1 cm away from the invasive breast cancer were selected as controls.The expressions of EMMPRIN,MMP-9 and KDM6B proteins in cancer-adjacent tissues,low-grade intraductal carcinoma tissues,high-grade intraductal carcinoma tissues and invasive breast cancer tissues were detected by immunohistochemistry.The relationship between the relative expressions of EMMPRIN,MMP-9 and KDM6B proteins and clinicopathologic features of invasive breast cancer was analyzed,Spearman correlation analysis was used to evaluate the correlation of EMMPRIN,MMP-9 and KDM6B proteins in breast cancer tissues,and receiver operating characteristic(ROC)curve was adopted to evaluate the diagnostic value of EMMPRIN,MMP-9 and KDM6B for invasive breast cancer.Results The relative expressions of EMMPRIN and MMP-9 proteins in high-grade intraductal carcinoma and invasive breast cancer tissues were significantly higher those in cancer-adjacent tissues and low-grade intraductal carcinoma tissues,and the relative expression of KDM6B protein was significantly lower than those in cancer-adjacent tissues and low-grade intraductal carcinoma tissues(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in invasive breast cancer tissues were significantly higher those in high-grade intraductal carcinoma tissues,and the relative expression of KDM6B protein was significantly lower than that in high-grade intraductal carcinoma tissues(P＜0.05);there was no statistically significant difference in the relative expressions of EMMPRIN,MMP-9 and KDM6B proteins between cancer-adjacent tissues and low-grade intraductal carcinoma tissues(P＞0.05).The relative expressions of EMMPRIN and KDM6B proteins were not related to the age,tumor location and tumor diameter of patients with invasive breast cancer(P＞0.05),and the relative expression of MMP-9 protein was not related to the age and tumor location of patients with invasive breast cancer(P＞0.05).Relative expressions of EMMPRIN,MMP-9 and KDM6B proteins were correlated with WHO grading,lymph node metastasis,and tumor,node and metastasis(TNM)staging of invasive breast cancer(P＜0.05),and the relative expression of MMP-9 protein was correlated with the tumor diameter(P＜0.05).In the WHO grades Ⅰ,Ⅱ,and Ⅲ of invasive breast cancer,the relative expressions of EMMPRIN and MMP-9 proteins increased sequentially,while the relative expression of KDM6B protein decreased sequentially(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in the lymph node metastasis group were significantly higher than those in the non-lymph node metastasis group,and the relative expression of KDM6B protein was significantly lower than that in the non-lymph node metastasis group(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in TNM stages Ⅲ-Ⅳ were significantly higher than those in stages Ⅰ-Ⅱ(P＜0.05),while the relative expression of KDM6B protein was significantly lower than that in stages Ⅰ-Ⅱ(P＜0.05).In the group of invasive breast cancer with diameter≤2 cm,2 to 5 cm,and＞5 cm,the relative expression of MMP-9 protein increased sequentially(P＜0.05).Spearman correlation analysis showed that the expression of EMMPRIN was positively correlated with MMP-9 protein in invasive breast cancer tissues(r=0.990,P=0.000),the expression of EMMPRIN was negatively correlated with KDM6B protein(r=-0.606,P=0.000),and the expression of MMP-9 was negatively correlated with KDM6B protein(r=-0.612,P=0.000).ROC curve analysis showed that the area under the curve(AUC)of EMMPRIN protein for diagnosing invasive breast cancer was 0.875[95％confidence interval(CI):0.823-0.926,P＜0.05],with an optimal threshold of 10.043,sensitivity of 79.0％,and specificity of 76.8％;the AUC of MMP-9 protein in diagnosing invasive breast cancer was 0.863(95％CI:0.808-0.917,P＜0.05),with an optimal threshold of 10.070,sensitivity of 74.2％,and specificity of 76.8％;the AUC of KDM6B protein in diagnosing invasive breast cancer was 0.267(95％CI:0.196-0.338,P＜0.05),with an optimal threshold of 11.003,sensitivity of 71.0％,and specificity of 98.6％.Conclusion EMMPRIN,MMP-9 and KDM6B are related to the occurrence and development of invasive breast cancer.Detection of the expressions of EMMPRIN,MMP-9 and KDM6B is helpful to the pathological diagnosis of invasive breast cancer and clinical judgment of invasion and metastasis of breast cancer.

Objective: To investigate the comorbidity of myopia and scoliosis among primary and secondary school students in Tianjin, and to analyze the school environment risk factors contributing to these health issues, so as to provide a scientific basis for development effective prevention measures. Methods: A total of 41 654 primary and secondary school students from 16 districts of Tianjin were selected by stratified random cluster sampling from September to October 2023 to screen for myopia and scoliosis. Univariate analysis was performed to examine the data, followed by a bivariate multivariate Logistic regression model and cumulative effect analysis to explore the influencing factors of their comorbidity. Results: In 2023, the prevalence of comorbidity of screening positive myopia and scoliosis among primary and secondary school students in Tianjin was 2.65%. The prevalence was higher in suburban areas (3.26%) compared to urban areas (2.02%), higher among females (3.81%) compared to males (1.59%), and highest in high school students (6.17%) compared to middle school (4.19%) and primary school students (0.44%) (χ2=62.23, 198.69, 953.19, P<0.01). Logistic regression analysis showed that the number of physical education classes ≥3 per week, the number of eye health exercises at school ≥2 per day, outdoor activities between classes, teachers reminding to pay attention to reading and writing posture and strict eye standing posture were negatively correlated with the comorbidity of screening positive myopia and scoliosis (OR=0.66, 0.77, 0.71, 0.78, 0.74, P<0.05). Reading or electronic screen while lying or lying on the stomach was positively associated with the comorbidity of screening positive myopia and scoliosis (OR=1.77, P<0.05). Cumulative effect analysis showed that the cumulative score (4-7, 7-9, ≥10) was negatively correlated with the comorbidity of screening positive of myopia and scoliosis (OR=0.65, 0.55, 0.52, P<0.05). Conclusions The school environment support and students personal behavior habits in school are related to the comorbidity of comorbidity of screening positive myopia and scoliosis. Prevention and control of myopia and scoliosis should improve the environmental factors related to students health in school.

Objective: To understand the potential categories of health risk behaviors among adolescents in the Wuling Mountain Area and their association with school connectedness, so as to provide reference for formulating classified and effective intervention measures. Methods: From March to June 2023, 3 386 middle and high school students from eight schools in the Wuling Mountain Area were selected using the multistage stratified cluster random sampling method. A basic information questionnaire, health risk behaviors questionnaire, and school connectedness scale were utilized for the survey. The latent classes of adolescent health risk behaviors in the Wuling Mountain Area were investigated by using latent class analysis, while an multinomial Logistic regression model was employed to analyze the association between latent classes and school connectedness. Results: Adolescent health risk behaviors in the Wuling Mountains Area were classified into three latent classes: high risk class of episodic behaviors ( 5.64 %), high risk class of implicit behaviors (26.90%), and low risk class of implicit behaviors (67.45%). Gender, ethnicity, and family type revealed significant differences in the distribution of the three latent classes ( χ 2=117.91, 22.55, 21.51, P <0.05). The results of the regression model analysis showed that, with the low risk class as the reference category, high school connectedness scores were associated with the high risk class of episodic behaviors ( OR=0.89, 95%CI = 0.88- 0.91) and the high risk class of implicit behaviors ( OR=0.90, 95%CI =0.89-0.91)( P <0.05). Conclusions The characteristics of adolescent health risk behavior classes in the Wuling Mountain Area are obvious. The high risk class of episodic behaviors and the high risk class of implicit behaviors are negatively correlated with school connectedness. Corresponding measures should be taken to enhance adolescents sense of belonging in school and reduce the aggregation and co occurrence of health risk behaviors.

Objective: To understand trends and related factors influencing overweight and obesity among primary and secondary school students in Tianjin, so as to provide a basis for formulating overweight and obesity prevention and control strategies. Methods: In September of each year from 2019 to 2023, a survey was conducted among 197 707 primary and secondary school students in 16 districts of Tianjin through a stratified random cluster sampling method. Physical examination was carried out in accordance with the Technical Standard for Physical examination for Student, and overweight and obesity survey was carried out. Basic information, smoking, drinking, diet, physical exercise, and sleep status were collected through questionnaire surveys. Results: The detection rates of overweight and obesity among primary and secondary school students in Tianjin from 2019 to 2023 were 39.07%, 43.33%, 41.54%, 43.92%, and 40.24%, respectively，showing an increasing trend(χ2trend=7.96,P<0.01). The detection rates of overweight increased in both vocational high schools and suburban counties (χ2trends=9.08, 47.18, P<0.01). The detection rates of obesity increased among both male and female students, in primary and vocational high schools and suburban counties (χ2trends=108.34, 15.99, 7.32, 10.95, 14.75, P<0.01). Multivariate Logistic regression analysis showed that smoking, drinking, unhealthful diet, and lack of proper physical exercise had a higher risk of obesity among primary and secondary school students (OR=1.26, 1.13, 1.08, 1.21, P<0.05). Stratified analysis showed that the risk of obesity was higher among boys with unhealthful and moderate lifestyle habits, as well as primary school students with unhealthful lifestyle habits (OR=1.15, 1.11, 1.27, P<0.05). Boys, girls and primary school students with unhealthful lifestyle habits, girls and ordinary high school students with moderate lifestyle habits had higher risk of being overweight (OR=1.14, 1.32, 1.21, 1.18, 1.40, P<0.05). Conclusions The detection rates of overweight and obesity among primary and secondary school students in Tianjin shows an increasing trend. Comprehensive lifestyle should be implemented to better prevent and control the risk of overweight and obesity.

Objective: To investigate the tendency of obesity and depressive symptoms in middle school students in Tianjin, so as to provide a reference for exploring the clustering patterns of health risk behaviors and their effects on obesity and depressive symptoms. Methods: A stratified cluster sampling method was used to investigate the obesity, depressive symptoms and health risk behaviors of middle school students from 16 counties of Tianjin from 2019 to 2023. The latent classes analysis was used to classify health risk behaviors. The χ 2 test and Logistic regression were used to analyze the effects of different categories on obesity and depression symptoms. Results: The obesity detection rate of middle school students in Tianjin from 2019 to 2023 first increased ( 20.90% in 2019, 23.35% in 2020) and then decreased and gradually stabilized (2021-2023:22.20%-22.69%), and the detection rate of depressive symptoms showed a decreasing trend (from 21.65% to 14.92%). The detection rate of comorbidity of obesity and depressive symptoms first increased (4.62% in 2019, 4.66% in 2020) and then gradually decreased to 3.43% in 2023, and the rate was higher in boys than in girls and higher in urban areas than in suburban areas. Latent category analysis classified health risk behaviors into four categories: lack of exercise group, poor behaviors such as sleep group, poor diet group and healthy group. After adjusting for demographic characteristics,the results of Logistic regression analysis showed that the co-occurrence risk of obesity and depression symptoms among the top three groups of middle school students were 1.35( OR=1.35, 95%CI =1.15-1.58), 4.20( OR=4.20, 95%CI =3.50-5.04), and 1.84( OR=1.84, 95%CI =1.40-2.38)times, compared to the healthy group ( P <0.05). Conclusions From 2019 to 2023, the comorbidity rate of obesity and depression among middle school students in Tianjin increased first and then decreased gradually. Interventions should be made in the aspects of exercise, diet, sleep and other behaviors.

Objective: To explore the causal relationship between adolescent school connectedness and the co-occurrence with health risk behaviors among junior high school students, so as to provide the reference for reducing the occurrence of adolescents health risk behaviors among junior high school students. Methods: A total of 924 students from two junior high schools in Jishou City were selected by the convenience sampling and cluster sampling methods, and two follow up surveys were conducted at 6 month intervals in April (T1) and October (T2) of 2023 using the Adolescent Health Risk Behavior Questionnaire and the School Connection Scale. The scores of the co-occurrence of school connectedness and health risk behaviors among junior high school students were compared by different survey periods and genders using the t-test, and cross lagged analyses were performed using Mplus 8.3 software. Results: School connectedness scores among junior high school students in T1 and T2 surveys were (38.86±7.46) (37.87± 7.71 ) and co-occurrence of health risk behaviors scores were (1.64±0.68) (1.83±0.53), respectively, and the differences between the scores of the 2 surveys were statistically significant ( t=4.24, -4.14, P <0.05). The correlation between school connectedness and co-occurrence of health risk behaviors were statistically significant in both surveys ( r =-0.46 to -0.33, P <0.05). Cross lagged analyses showed that school connectedness in T1 negatively predicted the co-occurrence of health risk behaviors in T2 ( β =-0.08), and the co-occurrence of health risk behaviors in T1 negatively predicted the school connectedness in T2 ( β =-0.15) ( P <0.05). Conclusions There is a longitudinal causal relationship between school connectedness and co-occurrence of health risk behaviors among junior high school students. School connectedness should be improved through various ways to reduce the co-occurrence of health risk behaviors.

Objective: To investigate the relationship between physical activity, sleep duration, overweight, obesity and depressive symptoms among middle school students in Tianjin, and to provide the evidence for targeted prevention of depression. Methods: In September 2019 to 2021, the stratified cluster sampling method was used to select 52 747 middle school students from 16 districts in Tianjin for questionnaire survey, including demographics, depressive symptom, sleep status and physical activity. The χ 2 test and multivariate Logistic regression were used to analyze the data. Results: The prevalence of depressive symptoms among middle school students in Tianjin was 19.07%, with higher prevalence in female, urban areas, resident students and left behind students ( χ 2=128.44, 155.77, 35.29, 19.15, P <0.05). The prevalence of overweight and obesity were 20.64% and 22.13%, the proportion of students who met physical activity, outdoor activity, sleep duration guideline were 49.54%, 33.64%, 25.77%, respectively. Logistic regression results showed that meeting the guidelines on physical activity, outdoor activity, sleep duration and BMI were negatively correlated with depression symptoms, with sleep duration showed the highest protective effects on depressive symptoms( OR=0.60, 95%CI =0.57-0.63, P <0.05). Compared with students who did not meet any guidelines, students who met 4 guidelines had a lower risk of depression symptoms( OR=0.39, 95%CI =0.34-0.46, P <0.05). Conclusion The prevalence of depressive symptoms of middle school students in Tianjin is in moderate level, and the intervention should be comprehensively administered in terms of sleep duration, physical activity, outdoor activities, as well as overweight and obesity to reduce the occurrence of depression symptoms among middle school students.
