Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Hepatic fibrosis refers to excessive accumulation and abnormal proliferation of fibrous connective tissue in the liver triggered by multiple pathogenic factors， and it may progress to liver cirrhosis， portal hypertension， and liver cancer. The pathological mechanisms of hepatic fibrosis involve hepatocyte injury， inflammatory cell infiltration with the release of inflammatory mediators， hepatic stellate cell activation， and extracellular matrix deposition. Recent studies have focused on mitochondrial dysfunction in disease progression， including the molecular pathways for hepatic fibrosis driven by metabolic disorders， energy deficiency， oxidative stress， mitochondrial dynamic imbalance， and autophagic dysfunction， all of which can induce liver injury. This article reviews the latest advances in hepatic fibrosis， in order to provide new therapeutic strategies for clinical management.

ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI， VIP， and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized， with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted， screening items using support degree， mean score， rank sum， and coefficient of variation. Item weights were determined using analytic hierarchy process （AHP）， gactor analysis （FA）， and combined weighting method （CWM）. The optimal weighting method was selected by comparing the area under the receiver operating characteristic （ROC） curve （AUC）. The Youden index was calculated to establish the diagnostic cutoff value， which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82， 0.85， and 0.86， with coordination coefficients of 0.648， 0.538， and 0.506， respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814， corresponding to a diagnostic cutoff of 8.361 （scaled to 40 points）. The final scale adopted a structured diagnostic framework： the symptom dimension requires at least 2 items， and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method， with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold （40 points） and structured diagnostic framework provide a quantitatively clear， clinically practical tool.

arcopenia is a systemic skeletal muscle disorder characterized by a decrease in skeletal muscle mass and progressive decline in function， with multiple signaling pathways involved in its occurrence and development. Among them， the AMP-activated protein kinase （AMPK） signaling pathway， as a key pathway regulating cellular energy homeostasis， plays an important role in the regulation of skeletal muscle metabolism and functional maintenance by improving abnormalities in glucose and lipid metabolism， balancing skeletal muscle protein synthesis and degradation， improving mitochondrial function， promoting autophagy， and inhibiting inflammatory responses and oxidative stress. This article reviews the research progress on how various traditional Chinese medicine （TCM） monomers， including polyphenols， flavonoids， and terpenoids； various traditional Chinese medicine extracts， such as those from Lycium barbarum ， Asini Corii Colla， and Panax quinquefolium ， and TCM compounds， such as Guiqi zhuangjin decoction， Jianpi qiangji granules， and Qigu capsules， intervene in sarcopenia by regulating the AMPK signaling pathway to promote muscle protein synthesis， inhibit protein degradation， improve mitochondrial function， and alleviate inflammation and oxidative stress. Additionally， their molecular mechanisms are explored. The aim is to deeply elucidate the basis of TCM in the prevention and treatment of sarcopenia and to provide theoretical support for the development of related innovative drugs.

Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas， as well as the relationship between pancreatic functions and traditional Chinese medicine （TCM） spleen system， this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ， but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation， ascent of the clear and dispersion of essence， which encompasses the endocrine and exocrine functions， and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess， so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities， with focus on restoring the pancreas （spleen）'s dispersing essence function. Therapeutic strategies include supplementing spleen qi， nourishing spleen yin to strengthen spleen earth， unblocking spleen collaterals， raising spleen yang， and removing spleen turbidity to support the spleen's dispersing essence function， so as to replenish the essential qi of zang-fu organs， ensure their distribution throughout the body， and improve the endocrine and exocrine functions of the pancreas.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

Objective: To analyze the monitoring results of key occupational hazard factors in workplaces across different industries in Aba Tibetan and Qiang Autonomous Prefecture (Aba Prefecture), Sichuan Province, so as to provide the basis for optimizing occupational disease prevention and control measures. Methods: Data of key occupational hazard factors in workplaces in Aba Prefecture from 2022 to 2024 were collected through the Workplace Occupational Hazard Monitoring System. Descriptive analyses were conducted on the over-standard rates of occupational hazard factors, completion rates of occupational health examinations, and participation rates in occupational health training. Results: From 2022 to 2024, 165 enterprise-times in Aba Prefecture were monitored, with 112 enterprise-times exceeding the standards, the over-standard rate of enterprises was 67.88%. A total of 1 005 worksite positions were monitored, with 302 exceeding the standards, the over-standard rate of worksite positions was 30.05%. The over-standard rates of enterprises and worksite positions showed upward trends from 2022 to 2024 (both P<0.05). The over-standard rates of enterprises in the ferrous metal mining and dressing industry and non-ferrous metal mining and dressing industry were both 100%. The top three over-standard rates of worksite positions were in the non-metallic mining and dressing industry, ferrous metal mining and dressing industry, and non-ferrous metal mining and dressing industry, at 62.50%, 56.00%, and 53.13%, respectively. Worksite positions exposed to silica dust, noise, and coal dust had relatively high over-standard rates, at 17.00%, 10.04%, and 7.27%, respectively. The actual numbers of physical examinations for personnel at worksite positions with dust, chemical factors, and physical factors were 9 398, 2 469, and 10 928 person-times, respectively, with completion rates of 95.78%, 81.03%, and 100.00%, respectively. The actual number of re-examinations were 428, 129, and 1 121 person-times, respectively, with re-examination rates of 64.26%, 27.27%, and 81.53%, respectively. Among the monitored enterprises, 102 enterprise-times participated in training for persons in charge, with a participation rate of 61.82%; 108 enterprise-times participated in training for occupational health management personnel, with a participation rate of 65.45%; and 10 489 person-times of workers exposed to hazards participated in occupational health training for workers, with a participation rate of 86.24%. Conclusions The over-standard rate of key occupational hazards factors in workplaces in Aba Prefecture was relatively high.

It is recommended to focus on strengthening the prevention and control of occupational hazard factors in the mining and dressing industry and promoting the effective implementation of occupational health examinations and occupational health training.

Background Pneumoconiosis is the most serious occupational disease in China, among which silicosis accounts for more than 50%. microRNA (miRNA) plays an important role in the occurrence process of silicosis fibrosis, but the mechanism of it has not been fully clarified yet. Objective To explore the molecular mechanism by which miR-411-3p modulates the ubiquitination degradation of SMAD specific E3 ubiquitin protein ligase (SMURF) 2/Smad7, thereby suppressing epithelial-mesenchymal transition (EMT) in mouse alveolar type II epithelial cells and counteracting silica-induced pulmonary fibrosis. Methods Twenty-four 8-week-old SPF male C57BL/6J mice were randomly divided into four groups: Control group, silica group, silica +miR-411-3p agomir-NC group, and silica +miR-411-3p agomir group, with 6 mice in each group. Silicosis model was prepared by a one-time bronchial infusion of silicon dioxide (SiO₂) (200 mg·mL^-1, 50 μL). In vitro MLE-12 cells were divided into (1) control group and SiO₂ group, (2) SiO₂+negative control siRNA (siRNA-NC) group and SiO₂+Smurf2 gene silencing (si-Smurf2) group, (3) SiO₂+solvent (DMSO) group and SiO₂+protease inhibitor (MG132) group, (4) mutant sequence plasmid (Mut)+miR-411-3p mimic control (miR-NC) group, Mut+miR-411-3p mimic group, wild sequence plasmid (Wt)+miR-NC group, and Wt+miR-411-3p mimic group, (5) SiO₂+miR-NC group and SiO₂+miR-411-3p mimic group. The pathological morphology and collagen deposition of lung tissue were observed after staining. Detection of miR-411-3p and proteins was conducted by real-time fluorescent quantitative PCR and Western blot. The binding of SMURF2 to Smad7 protein and Smad7 to ubiquitin (Ub) were detected by co-immunoprecipitation (Co-IP) method. Dual-luciferase reporter gene assay was adopted to verify the regulatory effect of miR-411-3p on Smurf2. Results In the SiO₂-induced MLE-12 cells, compared to the control group, the SiO₂-treated group showed significantly upregulated expressions of N-cadherin (N-Cad), collagen I (CoL I), SMURF2, transforming growth factor-β1 (TGF-β1), and phosphorylated Smad2/3 (p-Smad2/3). In contrast, the expressions of E-cadherin (E-Cad), Smad7, and miR-411-3p were significantly downregulated (P<0.05). The dual-luciferase reporter gene assay revealed a regulatory effect of miR-411-3p on Smurf2 (P<0.05). Meanwhile, in the MLE-12 cells induced by SiO₂, the miR-411-3p mimic down-regulated the protein expressions of SMURF2, N-Cad, CoL I, TGF-β1, and p-Smad2/3, while up-regulated the protein expressions of E-Cad and Smad7 (P<0.05). The silenced Smurf2 gene inhibited the expressions of N-Cad, CoL I, and p-Smad2/3 proteins, while promoted the expressions of E-Cad and Smad7 proteins in the MLE-12 cells (P<0.05). The Co-IP results showed that the binding of SMURF2 to Smad7 was enhanced, and the ubiquitin binding ability of Smad7 was enhanced in the SiO₂ group. In the lung tissue of mice, the results of pathological observation with hematoxylin-eosin (HE) and sirius red (VG) staining showed that compared with the agomir-NC, the lesion was relieved in the lung tissue of the miR-411-3p agomir group. Meanwhile, the expressions of SMURF2, N-Cad, CoL I, TGF-β1, and p-Smad2/3 were significantly down-regulated, while the expressions of E-Cad and Smad7 were significantly up-regulated (P<0.05). Conclusion MiR-411-3p alleviates the EMT of alveolar type II epithelial cells and antagonizes silicosis fibrosis progression in mice by inhibiting SMURF2-mediated ubiquitination and degradation of Smad7.

Background With the widespread application of ionizing radiation technology in non-medical fields, the number of non-medical radiation workers has steadily increased over the years. Individual dose monitoring serves as a crucial measure to safeguard the occupational health of non-medical radiation workers, as it can accurately identify occupational health risks and optimize radiation protection strategies. Objective To analyze the individual monitoring data of radiation workers from partial non-medical sectors in Shanghai from 2016 to 2023, to obtain the status of occupational radiation exposure and to provide a reference basis for non-medical radiation hygiene supervision and protection management. Methods The study subjects consisted of radiation workers from non-medical institutions in Shanghai who recieved individual dose monitoring at a Class-A radiation health technical service institution between 2016 and 2023. Under the Specifications for individual monitoring of occupational external exposure (GBZ 128-2019), thermoluminescence dosimetry was used for measuring personal dose equivalent, H_p(10), of various occupations encompassing industrial irradiation, industrial radiography, radioisotope production, accelerator operation, other industrial applications, education, and veterinary medicine. Kruskal-Wallis H test was used for comparison among multiple groups, Bonferroni method was adopted for pairwise comparison, and Mann-Kendall test was conducted for trend analysis to analyze the per-capita annual effective dose and its variation over time across different occupational categories of radiation workers. Results A total of 13728 person-times of non-medical radiation workers were monitored from 2016 to 2023, accumulating a collective effective dose of 3025.69 person-mSv. The per-capita annual effective dose M(P₂₅, P₇₅) was 0.14(0.08, 0.25) mSv. There were statistically significant differences in the per-capita annual effective dose of radiation workers in different years (H=874.826, P< 0.05). Similarly, significant variations were identified among various occupational categories (H=115.569, P< 0.05). Among them, the per-capita annual effective dose of radiological workers engaged in the production of radioactive isotopes was the highest, at 0.21(0.14, 0.32) mSv, followed by those in veterinary medicine, at 0.17 (0.11, 0.61) mSv; the difference between these two groups was not statistically significant (Z=1.231, P > 0.05), but both were significantly higher than those in other occupational categories (Z=3.913, 9.761, P<0.05). The veterinary medicine category had the highest proportion of monitored individuals with annual effective dose exceeding 1 mSv to the total number of monitored individuals(NR₁), reaching 17.12%, and the industrial radiography category showed the highest proportion of workers exposed to more than the annual investigation level 5 mSv to the total number of monitored individuals (NR₅), at 0.16%. Conclusion From 2016 to 2023, the overall individual doses of some non-medical radiation workers in Shanghai remain low, indicating well-controlled radiation levels in workplaces and low exposure risks. It is necessary to focus on radiation workers engaged in radioisotope production, veterinary medicine and industrial radiography.
