Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Liver fibrosis is the healing reaction of chronic liver injury caused by various factors such as viral infection， alcohol， and chemical substances and is a key link in the progression of chronic liver diseases to liver cirrhosis and liver cancer. Liver macrophages are considered important mediators of liver injury and repair， and the polarization trend of macrophages has a bidirectional regulatory effect on liver fibrosis. This article reviews the role of different phenotypes of liver macrophages in the development and progression of liver fibrosis， in order to provide new ideas for the prevention and treatment of fibrosis.

Elemene, derived from Curcuma wenyujin, one of the "8 famous genuine medicinal materials of Zhejiang province," exhibits remarkable antitumor activity. It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE Tian, introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".

Objective: To understand characteristics of men who have sex with men (MSM) who applied for HIV antibody self-testing reagents through "AIDS self-testing" column of a WeChat official account named "Dark Blue Public Health Center" in Tianjin City, so as to provide insights into exploring online modes of HIV antibody self-testing for MSM. Methods: Data of MSM who were 18 years old or above, currently lived in Tianjin City, had sex with men in the past six months and applied for HIV antibody self-testing reagents through "AIDS self-testing" column from May 2018 to December 2022 were collected. Demographic characteristics, results return and positive findings were descriptively analyzed. Results: Data of 2 064 MSM were collected, including 1 052 MSM aged 20 to 29 years (50.97%), 1 522 unmarried MSM (73.74%), 545 workers (26.41%), 1 385 MSM with college education or above (67.10%), and 315 MSM without testing for HIV antibody in the past (15.26%). A total of 6 470 self-testing reagents were applied, and 5 942 testing results were returned, with a return rate of 91.84%. There were 33.28% (687/2 064) of the applicants applying for 66.32% (4 291/6 470) reagents multiple times. There were 73 MSM with positive results, accounting for 1.23%. Conclusions The MSM applying for HIV antibody self-testing reagents through "AIDS self-testing" are mainly young and highly educated, including some who have never tested for HIV. However, attention should be paid to duplicate applications and the return rate should be increased.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective The aim of this study was to investigate the prospective association between physical activity (PA),independently or in conjunction with other contributing factors,and osteoporosis (OP) outcomes. Methods The Physical Activity in Osteoporosis Outcomes (PAOPO) study was a community-based cohort investigation. A structured questionnaire was used to gather the participants' sociodemographic characteristics. Bone mineral density (BMD) measurements were performed to assess OP outcomes,and the relationship between BMD and OP was evaluated within this cohort. Results From 2013 to 2014,8,471 participants aged 18 years and older were recruited from Tangshan,China's Jidong community. Based on their PA level,participants were categorized as inactive,moderately active,or very active. Men showed higher physical exercise levels than women across the activity groups. BMD was significantly higher in the very active group than in the moderately active and inactive groups. Individuals aged>50 years are at a higher risk of developing OP and osteopenia. Conclusion The PAOPO study offers promising insights into the relationship between PA and OP outcomes,encouraging the implementation of PA in preventing and managing OP.

Objective:To understand the prevalence of psychoactive substance use and its related factors in young men who have sex with men (YMSM) in Tianjin.Methods:From September 2017 to December 2022, a face-to-face anonymous questionnaire survey was conducted in MSM aged 16-24 years selected by snowball sampling in Tianjin, the main demographic and behavioral information of the YMSM were collected, and blood samples were collected from them for HIV test. Multivariate logistic regression analysis was used to identify related factors of psychoactive substances use.Results:A total of 2 919 YMSM were included in the study, in whom 47.1% (1 374/2 919) had ever used psychoactive substances. The rate of psychoactive substance use in YMSM who were not students was 51.6% (853/1 653), which was higher than that (41.2%, 521/1 266) in YMSM who were students ( χ2=31.42, P<0.001). In the YMSM who were not students, multivariate analysis showed that the OR of psychoactive substance use was 1.49 times higher in smokers than in non-smokers (95% CI: 1.17-1.84), 4.14 times higher in those who had anal sex in the past six months than in those who had no anal sex (95% CI: 1.71-9.98), 1.65 times higher in those who had ≥3 anal intercourses in the last week than in those who had <3 anal intercourses (95% CI: 1.27-2.14), 1.99 times higher in those who had commercial sex in the past six months than in those who had no homosexual commercial sex (95% CI: 1.14-3.45), 2.37 times higher in those who had HIV test in the last year than in those who had no HIV test (95% CI: 1.90-2.94), 1.89 times higher in those who had STD diagnosis in the last year than in those who had no STD diagnosis (95% CI: 1.11-3.21), 0.66 times higher in those who had the first homosexual sex at age ≥20 years than in those who had the first homosexual sex at age <20 years (95% CI: 0.52-0.83), 0.48 times higher in those who were heterosexual or bisexual than in those who were homosexual (95% CI: 0.30-0.74) and 0.70 times higher in those who mainly searched sexual partners offline than in those who mainly searched sexual partners online (95% CI: 0.53-0.94). Meanwhile, in the YMSM who were students, multivariate analysis showed that the OR of psychoactive substance use was 1.31 times higher in local residents than in non-local residents (95% CI: 1.02-1.69), 1.61 times higher in smokers than in non-smokers (95% CI: 1.14-2.27), 1.52 times higher in those who had ≥3 anal intercourses in the last week than in those who had <3 anal intercourses (95% CI: 1.05-2.19), 3.31 times higher in those who had STD diagnosis in the last year than in those who had no STD diagnosis (95% CI: 1.68-6.50) and 0.53 times higher in those in Han ethnic group than in those in minor ethnic groups (95% CI: 0.30-0.94). Conclusions:The prevalence of psychoactive substance use was high in YMSM in Tianjin, and the influencing factors varied in different groups (students or not). It is necessary to conduct targeted interventions for different groups.

Objective Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.Methods Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg·body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.Results In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group (P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h (P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h (P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.Conclusion Nanoplastics translocated rapidly to observed organs/tissues through blood circulation;however, only small amounts of MPs could penetrate the organs.

Objective To investigate the clinical effect of unilateral percutaneous vertebroplasty(PVP)combined with 3D printing technology for the treatment of thoracolumbar osteoporotic compression fracture.Methods A total of 77 patients with thoracolumbar osteoporotic compression fractures from October 2020 to April 2022 were included in the study,all of which were vertebral body compression fractures caused by trauma.According to different treatment methods,they were di-vided into experimental group and control group.Thirty-two patients used 3D printing technology to improve unilateral transpedicle puncture vertebroplasty in the experimental group,there were 5 males and 27 females,aged from 63 to 91 years old with an average of(77.59±8.75)years old.Forty-five patients were treated with traditional bilateral pedicle puncture vertebroplasty,including 7 males and 38 females,aged from 60 to 88 years old with an average of(74.89±7.37)years old.Operation time,intraoperative C-arm X-ray times,anesthetic dosage,bone cement injection amount,bone cement diffusion good and good rate,complications,vertebral height,kyphotic angle(Cobb angle),visual analogue scale(VAS),Oswestry disability index(ODI)and other indicators were recorded before and after surgery,and statistically analyzed.Results All patients were followed up for 6 to 23 months,with preoperative imaging studies,confirmed for thoracolumbar osteoporosis com-pression fractures,two groups of patients with postoperative complications,no special two groups of patients'age,gender,body mass index(BMI),time were injured,the injured vertebral distribution had no statistical difference(P＞0.05),comparable data.Two groups of patients with bone cement injection,bone cement dispersion rate,preoperative and postoperative vertebral body height,protruding after spine angle(Cobb angle),VAS,ODI had no statistical difference(P＞0.05).The operative time,intra-operative fluoroscopy times and anesthetic dosage were statistically different between the two groups(P＜0.05).Compared with the traditional bilateral puncture group,the modified unilateral puncture group combined with 3D printing technology had shorter operation time,fewer intraoperative fluoroscopy times and less anesthetic dosage.The height of anterior vertebral edge,kyphosis angle(Cobb angle),VAS score and ODI of the affected vertebrae were statistically different between two groups at each time point after surgery(P＜0.05).Conclusion In the treatment of thoracolumbar osteoporotic compression fractures,3D printing technology is used to improve unilateral puncture PVP,which is convenient and simple,less trauma,short operation time,fewer fluoroscopy times,satisfactory distribution of bone cement,vertebral height recovery and kyphotic Angle correction,and good functional improvement.

Objective:To retrospectively analyze the clinical characteristics and prognosis of 85 newly diagnosed patients with follicular lymphoma (FL), as well as the prognostic value of comprehensive geriatric assessment (CGA) in patients with FL aged ≥ 60 years old.Methods:The clinical data and prognosis of 85 newly diagnosed FL patients admitted from August 2011 to June 2022 were collected. The clinical features, laboratory indicators, therapeutic efficacy, survival and prognostic factors of patients were statistically analyzed, and the prognosis of patients was stratified using various geriatric assessment tools.Results:① The patients with FL were mostly middle-aged and older, with a median age of 59 (20-87) years, including 41 patients (48.2%) aged ≥60 years. The ratio of male to female was 1∶1.36. Overall, 77.6% of the patients were diagnosed with Ann Arbor stage Ⅲ-Ⅳ, and 17 cases (20.0%) were accompanied by B symptoms. Bone marrow involvement was the most common (34.1%). ②Overall, 71 patients received immunochemotherapy. The overall response rate was 86.6%, and the complete recovery rate was 47.1% of 68 evaluated patients. Disease progression or relapse in the first 2 years was observed in 23.9% of the patient. Overall, 14.1% of the patients died during follow-up. ③Of the 56 patients receiving R-CHOP-like therapies, the 3-year and 5-year progression-free survival (PFS) rates were 85.2% and 72.8%, respectively, and the 3-year and 5-year overall survival (OS) rates were 95.9% and 88.8%, respectively. The univariate analysis showed that age ≥60 years old ( HR=3.430, 95% CI 1.256-9.371, P=0.016), B symptoms ( HR=5.030, 95% CI 1.903-13.294, P=0.016), Prognostic Nutritional Index (PNI) <45.25 ( HR=3.478, 95% CI 1.299-9.310, P=0.013), Follicular Lymphoma International Prognostic Index (FLIPI) high-risk ( HR=2.918, 95% CI 1.074-7.928, P=0.036), and PRIMA-prognostic index (PRIMA-PI) high-risk ( HR=2.745, 95% CI 1.057-7.129, P=0.038) significantly predicted PFS. Moreover, age ≥60 years old and B symptoms were independent risk factors for PFS. Progression of disease within 24 months (POD24) significantly predicted OS in the univariate analysis. Conclusions:FL is more common among middle-aged and older women. Age, B symptoms, PNI score, FLIPI high-risk, PRIMA-PI high-risk, and POD24 influenced PFS and OS. The CGA can be used for treatment selection and risk prognostication in older patients with FL.
