1.Longitudinal cohort study on pubertal development trajectories of testicular and breast development among children
Chinese Journal of School Health 2026;47(3):408-412
Objective:
To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation.
Methods:
Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method.
Results:
Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years.
Conclusion
Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

OBJECTIVE To investigate the effect and mechanism of Tangzhi formula(TZF) on improving glucose and lipid metabolism disorders in type 2 diabetes mellitus (T2DM) rats.METHODS Thirty SPF-grade SD rats were used to establish a T2DM rat model through high-fat diet feeding combined with intraperitoneal injection of streptozotocin. After successful modeling, the rats were divided into the model group, metformin group (positive control, 0.18 g/kg), and TZF low-, medium-, and high-dose groups (5, 10, and 20 g/kg), with 6 rats in each group. An additional 6 rats were selected as the blank group. The rats in each group were orally administered the corresponding volume of drug solution or saline, and continuous dosing was performed for 6 weeks, once daily. Fasting blood glucose (FBG), area under the curve of oral glucose tolerance test (OGTT-AUC), area under the curve of intraperitoneal insulin tolerance test (IPITT-AUC), serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were measured. Hematoxylin-eosin (HE) staining and oil red O staining were used to observe hepatic pathological morphology and lipid deposition. Differentially expressed proteins in liver tissues were screened by proteomics analysis, and key proteins in signaling pathways were verified by Western blot and immunofluorescence staining.RESULTS Compared with the blank group, the levels of FBG, OGTT-AUC, IPITT-AUC, LDL-C, TG, and TC in the model group were significantly increased ( P <0.05), while HDL-C level was significantly decreased ( P <0.05); the liver tissues showed disordered hepatic cords, punctate necrosis of hepatocytes, and significant lipid deposition, the NAFLD activity score and positive area of lipid droplets were significantly increased( P <0.05). Compared with the model group, the above indicators in TZF low-, medium-, and high-dose groups and metformin group were significantly reversed ( P <0.05); hepatic pathological injury and lipid deposition were alleviated. Proteomics results showed that a total of 442 differentially expressed proteins were screened between the model group and the blank group, and 358 differentially expressed proteins were screened between the TZF high-dose group and the model group. Among these differentially expressed proteins, multiple proteins closely related to glucose and lipid metabolism showed a reversal trend after TZF intervention. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that the peroxisome proliferator-activated receptor (PPAR) signaling pathway was significantly enriched. The validation experiment results showed that TZF could significantly up-regulate the expression of PPARα, PPARγ, and apolipoprotein A1 (ApoA1) in rat liver tissues ( P <0.05), and down-regulate the expression of stearoyl-CoA desaturase 1 (SCD1) and perilipin 2 (PLIN2) ( P <0.05).CONCLUSIONS TZF can improve glucose and lipid metabolism disorders in T2DM rats; its mechanism may be related to the activation of the PPAR signaling pathway and the regulation of downstream lipid metabolism-related proteins SCD1, PLIN2, and ApoA1.
3.Mendelian randomization study of sleep duration and sleep disorders in relation to age at menarche in females
Chinese Journal of School Health 2026;47(7):1021-1025
Objective:
To determine the potential genetic causal relationship between sleep related phenotypes and female pubertal onset using the two sample Mendelian randomization approach.
Methods:
Genetic instrumental variables for sleep and age at menarche were sourced from FinnGen, IEU Open GWAS and GWAS Catalog three publicly available Genome Wide Association Study databases. Causal effects were estimated using the inverse variance weighted method, supplemented by sensitivity analyses and tests for heterogeneity, pleiotropy, and direction.
Results:
Genetically predicted sleep duration was positively associated with age at menarche ( β =0.61, 95% CI =0.30-0.91, P <0.01). Conversely, overall sleep problems ( β =-0.13, 95% CI =-0.20 to -0.07 ), two specific types of sleep disorders (sleep apnea: β =-0.10, 95% CI =-0.16 to -0.03; insomnia: β =-0.40, 95% CI = -0.69 to -0.11) were causally associated with earlier age at menarche (all P <0.01). Sensitivity analyses confirmed the robustness of these findings with consistent effect directions and no evidence of significant directional pleiotropy.
Conclusions
The study reveales a genetic causal relationship between sleep and pubertal onset. Adequate sleep duration appears to have a protective effect. These findings suggest that sleep may have a critical regulatory role in the initiation of pubertal development.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Methods:
Uterine exfoliative cells and vaginal secretions were collected from women aged 25-64 years in the resident population ( ≥6 months of residence) who participated in cervical cancer screening and human papillomavirus typing and vaginal microecology tests were performed to compare the status of HPV infections in different age groups.The study subjects were divided into HR-HPV-positive and HR-HPV-nega- tive groups according to whether HR-HPV infection was detected or not,and multifactorial Logistic regression anal- ysis was used to explore the relationship between HR-HPV and vaginal infectious diseases.
Results :
The HR-HPV infection rate of women in this study was 10. 43% ,and the HR-HPV infection rate of each age group was 14. 34% from 25 to 34 years old,10. 16% from 35 to 44 years old,8. 70% from 45 to 54 years old,and 11. 89% from 55 to 64 years old,and there were differences in the infection rate of HR-HPV among different age groups ( P < 0. 05) .Among HR-HPV,HPV52,HPV16,HPV58,HPV51,HPV68 were the most common,with 76. 69% of sin- gle infections,18. 02% of dual infections,4. 46% of triple infections,and 0. 83% of quadruple infections.HR- HPV single infections and multiple infections were prevalent in the age group of 25-34 years old and 55-64 years old.HR-HPV mono-infection and multi-infection rates were statistically different between age groups ( P<0. 05) . The infection rates of bacterial vaginosis ( BV) and trichomoniasis vaginitis ( TV) were higher in HR-HPV-positive patients ( P <0. 05) . Logistic regression analysis showed that the infection rates of BV ( OR = 1. 560,95% CI: 1. 195-2. 035 ) ,TV ( OR = 2. 208,95% CI: 1. 221 -3. 993 ) were risk factors for HR-HPV infection ( P < 0. 05) .
Conclusion
In the screened population of the Fourth Division of Xinjiang Production and Construction Corps,HR-HPV mono-infection is the most prevalent type.Women aged 25-34 and 55-64 years old show higher rates of HR-HPV infection.The most common HR-HPV genotypes,in descending order,are 52,16,58,51,and 68.BV and TV are the two major risk factors closely associated with HR-HPV infection.

Objective To investigate the levels of radionuclides in food in Beijing, China, and assess the committed effective dose to local residents from food intake. Methods From 2021 to 2022, a total of 65 food samples across 7 categories were collected in Beijing. The activity concentrations of radionuclides, including 137Cs, 210Pb, 238U, 228Ra, 226Ra, 40K, 90Sr, 210Po, 3H and 14C, were measured using gamma spectrometry and radiochemical methods. By combining the monitoring results with dietary consumption data of Beijing residents and the internal dose coefficients for Chinese reference adult phantom, the committed effective dose was estimated. Results The levels of radionuclides in food in Beijing were within the normal background range, consistent with related surveys in China and abroad, with activity concentrations below national standard limits. No significant differences were found in the activity concentrations of 137Cs, 238U, 228Ra, 226Ra and 40K between food samples collected from key areas and those from control areas (P > 0.05). The committed effective doses calculated according to internal dose coefficients for Chinese reference adult male phantom and GB 18871-2002 were 0.26 mSv and 0.19 mSv, respectively. Based on the Chinese reference adult male phantom, the majority of the committed effective dose was attributed to 210Pb (45.1%), 228Ra (37.1%), 210Po (12.3%), and 226Ra (4.7%). Conclusion The levels of radionuclides in food in Beijing fluctuated within the background range, resulting in a low radiation dose burden to the population.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.
