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.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

The mutual transformation and intertweaving of qi stagnation and blood stasis exist through the development and progression of pediatric pneumonia.Based on the pathogenic mechanism of qi stagnation and blood stasis obstructing the lungs and by analyzing the progression of pneumonia,this paper proposed that the traditional Chinese medicine(TCM)pathogenesis of pediatric pneumonia can be divided into three stages:early,middle,and late.In the early stage,external pathogens invade and then lead to lung qi stagnation and blockage.In the middle stage,qi stagnation and blood stasis block the lungs and then cause blood vessel stagnation.In the late stage,qi stagnation and blood stasis linger,and then result into the residual pathogens lurking in the lungs.Accordingly,the principles of treating pediatric pneumonia are proposed,i.e.,ventilating the lungs and dispelling pathogens,activating blood circulation and resolving stasis,relieving qi stagnation and unblocking blockage.The strategies for treating pediatric pneumonia in three stages are also introduced:for the early stage of pneumonia characterized by lung qi stagnation and blockage,the formula Yinqiao San combined with Wuhu Erchen Decoction are used for clearing lung-heat,resolving phlegm,and relieving wheezing;for the middle stage of pneumonia characterized by the intertweaving of qi stagnation and blood stasis,the formula Xuefu Zhuyu Decoction combined with Xuanfei Baidu Prescription are used for activating blood circulation and resolving stasis,ventilating the lungs and removing toxins,relieving qi stagnation and unblocking blockage;for the late stage of pneumonia characterized by qi stagnation and blood stasis lingering in the lungs,Qinghao Biejia Decoction and Qingfei Touxie Prescription are used by modification for clearing heat and nourishing yin,resolving blood stasis and relieving qi stagnation,nourishing yin and subduing yang.The approach to treating pediatric pneumonia from the pathogenic mechanism of qi stagnation and blood stasis obstructing the lung show significant efficacy on improving clinical symptoms in children with pediatric pneumonia and preventing the progression of pneumonia,and will provide reference to the clinical prevention and treatment of pediatric pneumonia.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective To explore whether liver cirrhosis markers aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4 index(FIB-4)based on blood biochemical indicators can predict disease free survival(DFS)and overall survival(OS)in patients with hepatocellular carcinoma(HCC)after resection.Methods 300 patients with HCC who underwent radical resection in Zhongshan Hospital,Fudan University from February 2005 to July 2017 were enrolled and the clinicopathological characteristics,recurrence and survival of these patients were retrospectively collected.The relationships between APRI,FIB-4 and postoperative recurrence and survival were evaluated.The ROC curve was used to evaluate the predictive values of APRI,FIB-4.Results The median follow-up of 300 patients was 61 months.Univariate Cox regression analysis showed that APRI,FIB-4,vascular invasion were risk factors affecting postoperative DFS and OS.The multivariate Cox regression analysis showed that vascular invasion was the independent risk factor for postoperative DFS(HR=1.518,95%CI 1.024-2.252,P=0.038)and OS(HR=2.301,95%CI 1.270-4.167,P=0.006).The time dependent ROC(time-ROC)curve showed that AUCs of APRI and FIB-4 predicting 1-year,3-year,and 5-year DFS were 0.555-0.596,which were 0.600-0.679 when predicting 1-year,3-year,and 5-year OS.Conclusions The predictive value of APRI and FIB-4 based on blood biochemical indicators alone for postoperative DFS and OS in HCC patients is limited.

Objective: To review the experience of using endoscopic retrograde cholangio-pancreatography (ERCP) in the clinical diagnosis and treatment of biliary complications during perioperative period of primary liver cancer at our hospital. Methods: A retrospective analysis was conducted on the clinical data of patients undergoing ERCP treatment for biliary complications during perioperative period of primary liver cancer at our hospital from October 2016 to June 2023. According to the indications of ERCP for biliary complications, the cases were divided into bile duct tumor thrombus group, bile duct stricture group, and bile leakage group. The baseline data, laboratory test results before and after ERCP treatment, treatment outcomes, and other datas of the patients with different types of biliary complication were statistically analyzed. Results: A total of 25 patients underwent 25 cases of ERCP, among which 23 patients were successfully cannulated, with a success rate of 92.0%. There were 14 cases of bile duct stenosis, mainly treated with biliary balloon dilation, probe dilation, stent implantation, and nasobiliary drainage; 6 cases of bile leakage, mainly treated with stent implantation and nasobiliary drainage; 5 cases of bile duct tumor thrombus, mainly treated with net basket and balloon thrombectomy, stent implantation, and nasobiliary drainage. After ERCP treatment, the patient's serum total bilirubin, serum direct bilirubin, and γ-glutamyl transferase significantly decreased compared to those before the treatment (P<0.05). The postoperative average amylase was (85.0±69.4)(21-306) U/L. No bleeding, gastrointestinal perforation, pancreatitis, or other ERCP-related complications occurred in all cases. Conclusions: Bile duct stricture is the most common biliary complication during the perioperative period of primary liver cancer. For these patients with biliary complications during perioperative period of primary liver cancer ERCP treatment is safe and effective.

Objective:To explore the uptake characteristics and temporal changes of 68Ga-fibroblast activation protein inhibitors (FAPIs) and 18F-FDG in the anastomotic site of reconstructed digestive tracts after radical surgery for gastrointestinal adenocarcinoma. Methods:A cohort of 43 patients (28 males, 15 females; age range 28-79 years) who underwent radical surgery for gastrointestinal adenocarcinoma and underwent 18F-FDG PET/CT follow-up between November 2020 and June 2022 in the First Affiliated Hospital of the Air Force Medical University was prospectively included. One week after the 18F-FDG PET/CT examination, 68Ga-FAPI-04 PET/CT imaging was performed. ROIs were drawn on the PET images at the highest uptake level of anastomotic sites of reconstructed digestive tract and abdominal wall incisions, and SUV max and target-to-background ratio (TBR) were determined. χ2 test, one-way analysis of variance, Kruskal-Wallis rank sum test (Bonferroni correction) and Wilcoxon signed-rank test were supplied. Results:There were 86 surgical wounds (13 gastric-intestinal anastomotic sites, 14 esophagus-intestinal anastomotic sites, 16 intestinal-intestinal anastomotic sites, and 43 abdominal wall incisions) included. In 68Ga-FAPI-04 PET imaging, SUV max of gastric-intestinal anastomotic sites was higher than that of abdominal wall incisions, with a statistically significant difference (adjusted P=0.014). The TBR did not show statistically significant differences among different types of surgical wounds ( H=3.88, P=0.275). In 18F-FDG PET imaging, SUV max of gastric-intestinal, esophagus-intestinal, and intestinal-intestinal anastomotic sites were all higher than that of abdominal wall incisions, with statistically significant differences (adjusted all P<0.001). There were no statistically significant differences in TBR among different types of surgical wounds ( H=3.02, P=0.388). In 68Ga-FAPI-04 PET imaging, the TBR of all types of anastomotic sites exhibited a decreasing trend with increasing postoperative time. Except for intestinal-intestinal anastomotic sites, the differences in TBR between < 0.5-year and ≥ 1.5-year groups were statistically significant for other types of surgical wounds (adjusted P<0.05). In 18F-FDG PET imaging, the TBR of abdominal wall incisions showed a decreasing trend with increasing postoperative time. However, the TBR of other types of surgical wounds did not show a decreasing trend, and the differences in TBR among different time groups were not statistically significant ( H values: 0.53-2.75, P values: 0.252-0.768). In comparing the two PET imaging agents, for all surgical wounds within the <0.5-year and 0.5-1.5-year groups, the 68Ga-FAPI-04 TBR was consistently higher than the 18F-FDG TBR ( z values: -3.17 and -2.55, P values: 0.002 and 0.011). However, in the ≥1.5-year group, the TBR values tended to be consistent, and the differences were not statistically significant ( z=-0.70, P=0.485). Conclusions:The 18F-FDG uptake in the anastomotic sites of reconstructed digestive tracts reaches a low level under half a year after surgery and does not significantly change over time, while the 68Ga-FAPIs uptake remains relatively high within the first 1.5 years after surgery but decreases over time. These patterns suggest that clinical attention should be paid to the differential diagnosis of anastomotic inflammation or fibrosis, which resulting in agent uptake and local tumor recurrence.
