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.

Background In recent years, the detection rate of thyroid nodules in China's occupational population has shown an upward trend. The prevalence of this disease needs to be taken seriously and targeted measures should be taken to address its influencing factors. Objective To analyze the detection and influencing factors of thyroid nodules among adult male workers in coal mining enterprises in Shanxi Province, and provide a theoretical basis for the prevention of thyroid nodules. Methods A total of 5195 adult male workers from coal mining enterprises who ordered physical examination provided by the Xishan Coal Electricity (Group) Corporation Occupational Disease Prevention and Control Institute in Taiyuan City, Shanxi Province from May 2023 to December 2023 were selected as research subjects. A questionnaire survey, physical examination, ultrasound examination, and biological sample collection and testing were conducted. Thyroid nodules were diagnosed based on ultrasound results, classified and evaluated according to the Chinese-Thyroid Imaging Reporting and Data System (C-TIRADS), and the crude detection rate and standardized detection rate of thyroid nodules in adult male coal mine workers in Shanxi Province wereestimated. Occupational history and occupational exposure information were retrieved from their annual occupational health examination reports provided by the employer. Logistic regression modeling was used to analyze the influencing factors of thyroid nodule. Results A total of 1688 cases of thyroid nodules were detected, with a crude detection rate of 32.49% and an age-standardized detection rate of 31.17%. The cases (constitution ratio) of thyroid nodules by category in the detected cases was as follows: 358 cases (21.21%) were classified as category 2, 1261 cases (74.70%) as category 3, 67 cases (3.97%) as category 4a, and 2 cases (0.12%) as category 4b. The results of logistic regression showed that the duration of exposure to occupational hazards for 11-20 years, 21-30 years, ≥31 years, average monthly working>26 days, and shift work were positively correlated with the detection of thyroid nodules (P<0.05), and the associated ORs (95%CIs) were 1.29 (1.01, 1.65), 1.55 (1.20, 1.99), 1.68 (1.26, 2.55), 1.19 (1.00, 1.40), and 1.15 (1.02, 1.29), respectively. Conclusion The duration of exposure to occupational hazards, average monthly working days, and shift work are influencing factors of thyroid nodules. Intervention measures should be developed based on these influencing factors to prevent the occurrence of thyroid nodules.

Zebrafish larvae are useful for identifying chemicals against lateral line (LL) hair cell (HC) damage and this type of chemical screen mainly focuses on searching for protectors against cell death. To expand the candidate pool of HC protectors, a self-built acoustic escape response (AER)-detecting system was developed to apply both low-frequency near-field sound transmission and AER image acquisition/processing modules. The device quickly confirmed the changed LL HC functions caused by most known ototoxins, protectors, and neural transmission modifiers, or knockdown of LL HC-expressing genes. With ten devices wired in tandem, five 'hit' chemicals were identified from 124 cyclin-dependent kinase inhibitors to partially restore cisplatin-damaged AER in less than a day. AS2863619, ribociclib, and SU9516 among the hits, protected the HCs in the mouse cochlea. Therefore, using free-swimming larval zebrafish, the self-made AER-detecting device can efficiently identify compounds that are protective against HC damage, including cell death and loss-of-function.

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.

Objective:To investigate the therapeutic effect of high-flow nasal cannula oxygen therapy (HFNC) and non-invasive positive pressure ventilation (NPPV) on patients with pulmonary edema caused by seawater drowning.Methods:A retrospective analysis method was used. Based on the Utstein database of emergency drowning in the First Hospital of Qinhuangdao, the clinical data of patients with seawater drowning pulmonary edema admitted to the emergency medicine department of the First Hospital of Qinhuangdao from January 1, 2019 to December 31, 2022 were collected. The patients were divided into NPPV group and HFNC group according to different ventilation methods. The general data, endotracheal intubation rate in 7 days, arterial blood gas analysis indexes [arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), arterial oxygen saturation (SaO 2)] and hemodynamic indexes (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, blood lactic acid) before and after treatment, length of stay in intensive care unit (ICU), oxygen therapy comfort of the two groups were compared. Results:A total of 54 patients were enrolled, including 21 patients in the NPPV group and 33 patients in the HFNC group. There were no significant differences in gender, age, state of consciousness and other general information between the two groups. Compared with NPPV group, the rate of endotracheal intubation in HFNC group within 7 days was significantly lower [24.2% (8/33) vs. 33.3% (7/21), P < 0.05]. Before treatment, there were no significant differences in arterial blood gas analysis and hemodynamics between the two groups. After treatment, the above indexes in both groups were significantly improved compared with those before treatment, and PaO 2, SaO 2, systolic blood pressure, diastolic blood pressure and mean arterial pressure in HFNC group were significantly higher than those in NPPV group [PaO 2 (mmHg, 1 mmHg≈0.133kPa): 93.56±6.37 vs. 82.14±6.25, SaO 2: 1.02±0.09 vs. 0.95±0.11, systolic blood pressure (mmHg): 117.37±8.43 vs. 110.42±8.38, diastolic blood pressure (mmHg): 79.43±7.61 vs. 72.21±4.32, mean arterial pressure (mmHg): 92.34±6.32 vs. 85.12±5.38], PaCO 2, heart rate and blood lactic acid were significantly lower than those in NPPV group [PaCO 2 (mmHg) : 34.26±5.63 vs. 37.24±6.22, heart rate (times/min): 73.38±7.56 vs. 86.25±5.41, blood lactic acid (mmol/L): 1.38±0.36 vs. 2.25±1.14], and the differences were statistically significant (all P < 0.05). In addition, the length of ICU stay in HFNC group was significantly shorter than that in NPPV group (days: 13.30±2.38 vs. 16.27±4.26), and the comfort rate of oxygen therapy was significantly higher than that in NPPV group [66.7% (22/33) vs. 42.8% (9/21)], with statistical significance (all P < 0.05). Conclusion:HFNC can improve the oxygenation of patients with pulmonary edema caused by seawater drowning, improve hemodynamics, reduce the rate of tracheal intubation, shorten the length of ICU stay, and improve the comfort of oxygen therapy, which has certain clinical application value.

Diabetic nephropathy （DN） is a chronic microvascular complication in diabetic patients and the main cause of end-stage renal disease （ESRD）. Studies have shown that nuclear factor kappa-B （NF-κB） signaling pathway is involved in the pathological process of DN by activating pathological mechanisms such as inflammation， oxidative stress， fibrosis， apoptosis， autophagy， and pyroptosis. Therefore， blocking the transduction of NF-κB signaling pathway can help prevent and treat DN. Currently， western medical treatment involves strategies such as lowering blood sugar， blood pressure， and lipids， as well as using endothelin receptor antagonists， mineralocorticoid receptor antagonists， aldosterone synthase inhibitors， and other drugs， but they still cannot block the pathological process of DN. Traditional Chinese medicine （TCM） offers a simpler and more cost-effective approach that addresses both the symptoms and underlying causes of DN. Recent research has shown promising results in managing DN with TCM， and NF-κB， as a key factor， plays an important role in the prevention and treatment of DN. This article summarized the research results of TCM based on the NF-κB signaling pathway for the treatment of DN in the past five years. It described a variety of TCM extracts， such as polysaccharides， terpenes， phenols， flavonoids， saponins， and alkaloids， as well as TCM compound prescriptions such as Huaiqihuang granules， Astragalus mongholicus Bunge and Panax notoginseng formula， and Danzhi Jiangtang capsules， which regulated the NF-κB signaling pathway and its upstream and downstream factors to block the pathological process of DN. This inhibition aims to prevent renal pathological damage caused by DN and slow down the deterioration of renal function. The article aims to provide new ideas and references for the research and development of drugs for the prevention and treatment of DN.

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery.Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients,and is widely recommended as a first-line clinical treatment.But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices.To address this issue,this consensus,based on a comprehensive literature review and clinical experiences of experts,systematically summarizes the indications,target patients,and contraindications of minimally invasive tooth extraction,the overall workflow of this procedure(preoperative preparation,surgical steps,postoperative management,postoperative instructions,medications,and follow-up),and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Objective:To investigate the efficacy of robot-assisted femoral tunnel localization in reconstruction of the medial patellofemoral ligament (MPFL).Methods:A retrospective study was conducted to analyze the 36 patients who had been admitted to Department of Sports Medicine, The Fourth Hospital of Wuhan between January 2019 and January 2022 due to recurrent patellar dislocation. There were 15 males and 21 females; age: 23.5 (18.3, 29.0) years; number of dislocations: 2.5 (2.0, 3.0). They were stratified into 2 cohorts based on utilization of robot-assistance. In the observation group (17 cases), the femoral tunnel localization was robot-assisted in MPFL reconstruction; in the control group (19 cases), the femoral tunnel localization was guided by C-arm fluoroscopy in MPFL reconstruction. The 2 groups were compared in terms of operation time, frequency of guide wire placement, visual analogue scale (VAS) at postoperative 1 d, patellar tilt angle (PTA) and the disparity between actual femoral tunnel insertion and ideal tunnel insertion point (Sch?ttle point) at postoperative 1 to 3 d, and Lysholm knee score and International Knee Documentation Committee (IKDC) score at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for 12.0 (10.3, 13.0) months. In the observation group, the operation time [(64.1±16.7) min], frequency of guide wire placement [1.0 (1.0, 2.0) times], VAS [2.5 (2.0, 3.0) points], and disparity between actual femoral tunnel insertion and ideal tunnel insertion point [(4.7±1.2) mm] were significantly better than those in the control group [(84.2±19.7) min, 3.0 (2.0, 4.0) times, 3.5 (3.0, 4.0) points, and (6.1±1.2) mm] ( P<0.05). There was no statistical difference between the 2 groups in PTA, Lysholm knee score or IKDC score ( P>0.05). Conclusions:The short-term clinical efficacy of robot-assisted femoral tunnel localization is satisfactory in MPFL reconstruction. Compared with the intraoperative C-arm fluoroscopy, robot-assisted localization can decrease the frequency of guide wire placement, enhance femoral tunnel accuracy and efficiency, and alleviate more postoperative pain for the patients.

Objective To analyze the independent factors impacting the in-hospital prognosis of patients with septic shock,and to construct a simplified scoring system and evaluate its predictive value.Methods A retrospective analysis was carried out on 247 patients with septic shock admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from January 2021 to July 2022,among whom 122 patients survived and 125 died.Univariate analysis and multivariate Cox proportional hazard regression model were used to screen the independent factors affecting in-hospital mortality of septic shock patients.The best cut-off value was ob-tained by using the receiver operating characteristics(ROC)curve,and the continuous variables were conver-ted into binary variables and assigned.Finally,a simplified scoring system was established,and its predictive efficacy for hospital death in septic shock patients was verified.Results The results of multivariate Cox pro-portional hazard regression model showed that the Glasgow coma scale(GCS)score(HR=0.929,95%CI:0.875-0.985,P=0.014),quick sequential organ failure assessment(qSOFA)score(HR=1.475,95%CI:1.094-1.989,P=0.011),lactate level(HR=1.096,95%CI:1.049-1.145,P<0.001),procalcitonin level(HR=1.009,95%CI:1.000-1.018,P=0.048),and albumin level(HR=0.958,95%CI:0.922-0.996,P=0.029)were identified as independent influencing factors for in-hospital mortality in patients with septic shock.The ROC curve showed that the simplified scoring system,based on GCS score,qSOFA score,lactate,procalcitonin,and albumin levels,exhibited an area under the curve and 95%CI of 0.866(0.822-0.910),with an optimal cutoff value of 2.5.The sensitivity and specificity were 80.0%and 78.7%,respectively.Con-clusion The simplified scoring system,based on early assessments of GCS score,qSOFA score,lactate,pro-calcitonin,and albumin levels,demonstrates substantial predictive value for in-hospital mortality in patients with septic shock.
