Background The prevalence of hyperuricemia (HUA) among Chinese residents has been increasing annually, with occupational populations facing a higher risk of HUA due to shift work or obesity. Objective To investigate the impact of shift work and obesity on HUA among coal miners, and to provide scientific data for the prevention of HUA in this occupational group. Methods A cross-sectional study was conducted with 25619 workers from a coal mining group in 2023 as the study population, using a questionnaire survey and occupational health check-ups. Workers who were retired or on medical leave, as well as those who provided incomplete responses to the questionnaire or did not complete anthropometric measurements or blood tests, were excluded. A total of 23173 participants were included in the study. An unconditional logistic regression model was used to analyze the association between HUA and selected factors such as shift work status, years of shift work, daily shift work hours, body mass index (BMI), waist-to-height ratio (WHtR), and visceral adiposity index (VAI), as well as the interaction between obesity and shift work on HUA. Restricted cubic spline functions were used to analyze the dose-response relationship between years of shift work, daily shift work hours, and HUA. Results The average age of the included workers was (42.38 ± 9.82) years. A total of 6735 workers reported positive HUA, with a positive rate of 29.1%, and the prevalence was higher in men compared to women (31.8% vs. 13.9%). After adjusting for confounding factors, the restricted cubic spline model revealed a nonlinear dose-response relationship between years of shift work, daily shift work duration, and HUA: ① When the years of shift work exceeded 3.25 years, the risk of HUA in workers gradually increased with longer work duration. At 20 years of shift work, the risk increase showed a "saturation effect," meaning that the risk of HUA no longer increased with additional years of shift work. ② When daily shift work duration was below 10 h, the risk of HUA increased with the length of shift work, but after exceeding 10 h, the risk stabilized. After adjusting for confounding factors, the logistic regression model showed that, compared to non-shift workers, shift workers, those with 10-20 years and over 20 years of shift work experience, as well as those working less than 8 h and more than 8 h per day, had a higher risk of HUA, with odds ratios (OR) of 1.14 (95%CI: 1.06, 1.22), 2.42 (95%CI: 2.20, 2.67), 2.23 (95%CI: 2.00, 2.48), 1.41 (95%CI: 1.29, 1.54), and 1.90 (95%CI: 1.75, 2.06), respectively. Additionally, compared to individuals with normal obesity indices, those with overweight and obesity based on BMI, high and very high VAI and excessive WHtR had a higher risk of HUA, with ORs of 2.01 (95%CI: 1.85, 2.17), 3.51 (95%CI: 3.20, 3.84), 1.42 (95%CI: 1.32, 1.54), 2.10 (95%CI: 1.91, 2.30), and 1.82 (95%CI: 1.69, 1.97), respectively. The interaction analysis showed no interaction between shift work and obesity index (both P_s < 0.001). Conclusion Shift work, longer shift work years, and longer daily shift work hours increase the risk of HUA among coal miners. Additionally, the role of obesity in the development of HUA cannot be ignored.

Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals"， it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure， qi and liquid imbalance， and kidney collaterals impairment， and it is proposed that the treatment principle is to nourish the sweat pore， regulate qi and fluid， and supplement the kidney and unblock the collaterals. In clinic， guided by sequential therapy and according to the different disease mechanism characteristics of the four stages， including early stage of the disease， hormone induction stage， hormone reduction stage， hormone maintenance stage， the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency， modified Zhenwu Decoction （真武汤） was applied to warm yang and drain water； for hormone induction stage with yin deficiency resulting in effulgent fire， modified Zhibai Dihuang Pill （知柏地黄丸） plus Erzhi Pill （二至丸） was used to enrich yin and reduce fire； for hormone reduction stage with qi and yin deficiency， modified Shenqi Dihuang Decoction （参芪地黄汤） was used to boost qi and nourish yin； for hormone maintenance stage， modified Shenqi Pill （肾气丸） was used to supplement yin and yang. Meanwhile， the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals， so as to providing ideas for clinical treatment.

Anterior cruciate ligament (ACL) injury is a common disease of the knee joint, which affects the stability of the knee joint. As an emerging field, artificial intelligence (AI) has developed rapidly in the diagnosis and treatment of ACL injury in recent years, improving the accuracy and timeliness of the whole diagnosis and treatment process to improve the prognosis of ACL injury. This article reviews the research progress of AI in diagnosis of ACL injury, ACL reconstruction, prediction of postoperative outcomes, and postoperative rehabilitation. We hope this information may help surgeons to improve the success rate of AI in diagnosis and treatment of ACL injury and provide cutting-edge technical support to improve patient outcomes.

As space stations steadily progress into the application and development stage,astronauts will be regularly rotated for space missions,and the impact of the space environment on human health will become an important research topic.Under microgravity,astronauts lose 1%～2%bone mass per month.Astronauts'health phenotype,as well as animal experiments conducted in space,have shown that microgravity leads to significant loss of weight-bearing bone and reduction of ultimate loading in bones.Due to the limited conditions,it is not easy to conduct experiments in space,so various animal models have been used for simulated microgravity experiments to study the mechanisms of bone loss.This review summarizes many studies on osteoporosis under space microgravity and simulated microgravity on the ground,describing different types of bone loss and underlying molecular mechanisms caused by microgravity,as well as the similarities and differences of current conclusions.In addition,this review summarizes the effects of non-bone tissues such as muscles on bone loss under microgravity,and the current measures adopted in the space station to prevent osteoporosis.

Objective: To investigate the regulatory role of Porphyromonas gingivalis(Pg) infection on the EGFR/GSK3β signaling axis, and its impact on epithelial-mesenchymal transition(EMT) and cetuximab(Ctx) resistance in esophageal squamous cell carcinoma(ESCC). Methods: Single cell RNA sequencing was employed to perform differential analysis of cellular subpopulations, identifying differentially expressed genes in ESCC tissues infected and non-infected with Pg. IHC was conducted to assess the expression of Pg and epidermal growth factor receptor(EGFR) in ESCC tissues. Western blot, RT-PCR, and IF staining were performed to evaluate EGFR expression in Pg infected ESCC cell lines KYSE70 and TE1. ESCC cells were treated with Pg and EGFR inhibitor Ctx, and divided into four groups: control(NC) group, Pg group, Ctx group, Pg+Ctx group. Cell proliferation, migration and invasion abilities were evaluated using CCK-8, plate cloning, wound healing and Transwell assay. Western blot analysis was performed to detect the expression of EMT and EGFR/GSK3β signaling pathway-associated proteins and their phosphorylation levels. Transforming growth factor-β1(TGF-β1) was used to induce EMT in ESCC cells, promoting a transition from the epithelial phenotype to mesenchymal-like phenotype. The differential effects of Ctx on these two phenotypic states were subsequently compared. Results: Epithelial cells were predominantly enriched in Pg-positive tissues, and Pg infection promoted the upregulation of EGFR expression in ESCC cells. Compared to the NC group, Pg treatment significantly enhanced the proliferation, invasion and migration capabili-ties of ESCC cells, and also increased chemoresistance to Ctx and reduced its antitumor efficacy. Pg induced EMT in ESCC cellsviathe EGFR/GSK3β signaling pathway. Notably, Ctx exhibited markedly weaker inhibitory effects on mesenchymal-like cells compared to epithelial ESCC cells. Conclusion Pg promotes ESCC cells proliferation, invasion and migration by regulating EMT through the EGFR/GSK3β signaling pathway, and enhances chemoresistance to Ctx.

IgA vasculitis is a common childhood vasculitis disorder.Its primary clinical manifestation is cutaneous purpura,which is often accompanied by gastrointestinal and joint symptoms.Renal involvement can present as hematuria or proteinuria.This condition is recurrent and protracted,significantly affecting the health of children.The pathogenic factors in pediatric IgA vasculitis are diverse."Wind-toxin damaging collaterals"is presented as the core pathogenesis based on clinical practice and theoretical exploration.This concept essentially entails the latent attack of wind-toxin,collateral damage leading to blood extravasation,and healthy qi deficiency and lingering toxins,with the disease primarily located in the collateral vessels.The disease course is divided into three stages:acute,lingering,and recovery.Clinical practice should adhere to the pathogenesis principles and apply stage-based pattern differentiation and treatment.The acute stage involves wind-toxin attacking collaterals with dampness-heat accumulation.Treatment focuses on dispersing wind,clearing heat,and eliminating dampness to expel wind-toxin from the muscular exterior.The self-prescribed Qufeng Xiaodian Formula is a frequently selected modified formula.The lingering stage features latent wind-toxin in the collaterals and congealed accumulations in the kidney collaterals.Treatment aims to resolve wind-toxin,disperse stasis,and eliminate accumulation to remove densely accumulated wind-toxin.A modified Taohong Siwu Decoction is selected.The recovery stage involves deficient healthy qi with persistent wind assault and lingering toxins.Emphasis should be placed on cultivating the fundamental,strengthening the root,and nourishing yin,as well as supporting the healthy qi to dispel wind and expel toxins,while conditioning the body to prevent recurrence.A modified Guomin Decoction is selected.Clinical application emphasizes the combination of characteristic medicines,such as wind medicines to expel pathogens,insect medicines to identify collaterals,and vine medicines to unblock the meridians,to enhance the effects of identifying wind,resolving toxins,unblocking collaterals,and dispersing congealed accumulations.This study aims to systematically elaborate on the stage-based treatment strategy from the perspective of"wind-toxin damaging collaterals,"providing a theoretical basis and clinical practice reference for the traditional Chinese medicine diagnosis and treatment of pediatric IgA vasculitis.
