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.

Objective To investigate the value of qualitative and quantitative characteristics of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI in preoperative prediction of vessels encapsulating tumor clusters(VETC)pattern in hepatocellular carcinoma(HCC).Methods A total of 234 patients diagnosed with HCC by pathology were analyzed retrospectively.A total of 101 VETC-positive HCC patients and 133 VETC-negative HCC patients were included.All patients were divided into training group and validation group according to 7︰3.The training group data were used to construct a prediction model for VETC-positive HCC.Receiver operating characteristic(ROC)curve was drawn and the area under the curve(AUC)was calculated to verify the diagnostic efficiency of the model.Calibration curve was drawn to verify the calibration of the model.Results Multivariate logistic regression analysis predicted the independent risk factors for VETC-positive HCC:portal phase peripheral washout[odds ratio(OR)6.493],necrosis or severe ischemia(OR 4.756),targetoid transitional phase or hepatobiliary phase(OR 0.307),and lesion to liver signal intensity ratio(LLR)on arterial phase(OR 0.074).The AUC of the training group in predicting VETC-positive HCC was 0.790[95%confidence interval(CI)0.720-0.859].The AUC of the validation group in predicting VETC-positive HCC was 0.779(95%CI 0.668-0.889).The calibration curve diagram showed that the calibration curve(the slope was 0.91)almost coincides with the ideal curve,indicating that the prediction model had better calibration.Conclusion The qualitative and quantitative characteristics of Gd-EOB-DTPA enhanced MRI can be used to predict VETC-positive HCC preoperatively,the independent risk factors of VETC include portal phase peripheral washout,necrosis or severe ischemia,targetoid transitional phase or hepatobiliary phase,and LLR on arterial phase.

Objective:To investigate the predictive value of albumin-to-fibrinogen ratio (AFR) for postoperative acute kidney injury (AKI) in infants with ventricular septal defect repair under cardiopulmonary bypass (CPB).Methods:A retrospective analysis was conducted on infants diagnosed with ventricular septal defect in Anhui Children's Hospital from January 2019 to July 2023. The infants were divided into AKI group and non-AKI group according to whether AKI occurred in hospital after operation. Demographic data, preoperative data, intraoperative data, postoperative data and laboratory results during CPB were collected. Multivariate Logistic regression analysis was used to find the factors of AKI after ventricular septal defect repair with CPB. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of AFR for postoperative AKI after ventricular septal defect repair with CPB.Results:A total of 215 children were collected, including 28 in AKI group and 187 in non-AKI group. There were no significant differences in age, gender, body weight, height, history of pneumonia and history of chronic heart failure between the two groups, but the left ventricular ejection fraction (LVEF) in the AKI group was significantly lower than that in the non-AKI group (0.526±0.028 vs. 0.538±0.030, P = 0.048). The duration of CPB (minutes: 74.1±12.1 vs. 65.8±11.3, P < 0.001), aortic cross-clamping (minutes: 41.7±9.7 vs. 37.2±9.4, P = 0.021) and hypothermic circulation arrest (21.4% vs. 8.6%, P = 0.047) in AKI group were significantly higher than those in non-AKI group, but there were no significant differences in the proportion of ultrafiltration and urine volume between the two groups. The length of intensive care unit (ICU) stay in AKI group was significantly longer than that in non-AKI group (days: 5.3±2.0 vs. 4.0±1.7, P < 0.001), but there were no significant differences in duration of mechanical ventilation and the proportion of postoperative hypotension between the two groups. During CPB, the levels of blood glucose (mmol/L: 9.4±1.3 vs. 8.8±0.8, P < 0.001), blood lactic acid (mmol/L: 2.2±0.3 vs. 2.0±0.3, P = 0.015) and serum creatinine (μmol/L: 79.7±11.5 vs. 74.4±10.9, P = 0.018) in AKI group were significantly higher than those in non-AKI group, while the AFR was significantly lower than that in non-AKI group (8.5±1.3 vs. 10.2±1.6, P < 0.001), but there were no significant differences in the levels of hemoglobin, blood urea nitrogen, alanine aminotransferase and aspartate aminotransferase between the two groups during CPB. Multivariate Logistic regression showed that AFR was a protective factor for AKI after ventricular septal defect repair with CPB [odds ratio ( OR) = 0.439, 95% confidence interval (95% CI) was 0.288-0.669, P < 0.001]. Blood glucose ( OR = 2.133, 95% CI was 1.239-3.672, P = 0.006) and blood lactic acid ( OR = 5.568, 95% CI was 1.102-28.149, P = 0.038) were risk factors for AKI after ventricular septal defect repair with CPB. ROC curve analysis showed that the area under the curve (AUC) of AFR in predicting AKI after ventricular septal defect repair with CPB was 0.804 (95% CI was 0.712-0.897, P < 0.001). When the optimal cut-off value was less than 9.05, the corresponding sensitivity was 75.0% and the specificity was 72.7%. Conclusions:Low AFR (≤9.05) during CPB is an independent risk factor for AKI after ventricular septal defect repair with CPB. AFR during CPB has a high predictive value for postoperative AKI after ventricular septal defect repair with CPB.

Objective To observe the value of the scoring model of MRI features for predicting proliferative hepatocellular carcinoma(HCC).Methods Data of 241 patients with pathologically confirmed HCC,including 90 cases of proliferative HCC and 151 cases of non-proliferative HCC were analyzed retrospectively.Univariate and multivariate logistic regression were used to compare the clinical and MRI findings evaluated according to liver imaging reporting and data system version 2018 between groups.The independent predictive factors of proliferative HCC were screened,and scores were assigned according to the weight,then a scoring model was constructed.Receiver operating characteristic(ROC)curve was drawn,and the area under the curves(AUC)were calculated to assess the predictive efficacy of this model.The patients were divided into high and low proliferation risk subgroups based on the optimal score thresholds.The recurrence free survival(RFS)rates and early RFS rates were compared between groups and subgroups.Results MRI showed tumor corona enhancement,arterial phase annular hyper-enhancement,intratumoral vessels,much focus parenchymal low enhancement and irregular tumor margins were all independent predictive factors for proliferative HCC(OR=3.287,2.362,4.542,2.997,2.379,all P＜0.05),which were then were scored with 7,5,9,7 and 5,respectively,with a total score of 0-33.AUC of the obtained scoring model for predicting proliferative HCC was 0.818.Taken 9 points as the optimal score thresholds,97 cases were assigned into high proliferation subgroup and 144 into low proliferation risk subgroups).Significant differences of RFS rates and early RFS rates were found between groups and subgroups(all P＜0.05).Conclusion MRI features scoring model could effectively predict proliferative HCC.

Objective:To explore the status quo and influencing factors of postnatal sense of security in patients with hypertensive disorder complicating pregnancy.Methods:This study was a cross-sectional study. Using the convenience sampling method, a total of 215 patients with hypertensive disorder complicating pregnancy and their spouses who gave birth in Women's Hospital of Nanjing Medical University from December 2022 to May 2023 were selected as the research objects. The general data questionnaire, Parents' Postnatal Sense of Security (PPSS), Ego-Resiliency Scale (ERS) and Perceived Social Support Scale (PSSS) were used to investigate them. Multiple linear regression analyses were used to explore the factors influencing postpartum security in patients with hypertensive disorders complicating pregnancy.Results:A total of 215 questionnaires were sent out in this study, and 202 were effectively collected, with an effective recovery rate of 94.0%. The total score of PPSS maternal version for 202 patients with hypertensive disorder complicating pregnancy was (59.32±6.81), while the total score of PPSS paternal version for spouses was (41.28±5.24). The results of multiple linear regression analysis showed that the number of antenatal examinations accompanied by family members, the effect of postpartum blood pressure control, the current state of mother and child, postnatal sense of security of spouse, ego-resiliency and perceived social support were the influencing factors of postnatal sense of security in patients with hypertensive disorder complicating pregnancy ( P<0.05) . Conclusions:The postnatal sense of security in patients with hypertensive disorder complicating pregnancy is at a medium high level. Medical personnel should focus on patients with hypertensive disorder complicating pregnancy who are accompanied by their family members less times, poor postpartum blood pressure control and postpartum separation from mother and child, providing them with targeted clinical care to improve their postnatal sense of security.

Objective To investigate the value of the liver imaging reporting and data system v2018(LI-RADS v2018)and other imaging features in predicting preoperative risk and postoperative prognosis of isolated macrotrabecular-massive hepatocellular carcinoma(MTM-HCC).Methods Patients with isolated hepatocellular carcinoma(HCC)confirmed by pathology after preoperative MRI examination were selected,and all patients were randomly assigned to a training group(n=146)and a validation group(n=62)in a 7∶3 ratio.Least absolute shrinkage and selection operator(LASSO)regression and multivariate logistic regression were used to screen independent prognostic factors of MTM-HCC and construct a nomogram.Patients were stratified into high-risk and low-risk subgroups based on the nomogram scores.Kaplan-Meier survival curves and Log-rank tests were used to compare the recurrence-free survival(RFS)among different subgroups of patients.Results Multivariate logistic regression analysis revealed that intratumoral vessels[odds ratio(OR)=3.480,95％confidence interval(CI)1.110-10.912,P=0.032],arterial phase hypovascular component ≥20％(OR=4.615,95％CI 1.728-12.321,P=0.002),and corona enhancement(OR=4.814,95％CI 1.816-12.766,P=0.002)were independent predictors of MTM-HCC.The nomogram constructed based on these indicators demonstrated area under the curve(AUC)of the receiver operating characteristic(ROC)curve was 0.834 and 0.764 for predicting MTM-HCC in the training and validation groups,respectively.The RFS predicted by the nomogram was significantly different between the high-risk and low-risk subgroups and both the pathologically confirmed MTM-HCC positive and negative groups(P＜0.05).Conclusion Intratumoral vessels,arterial phase hypovascular component ≥20％,and corona enhancement are independent predictors of MTM-HCC.The constructed nomogram based on these predictors demonstrates good diagnostic efficacy for MTM-HCC and has significant prognostic value for patients'RFS.

Objective:To summarize the clinical and genetic features of 7 patients with a mild form of Geleophysic dysplasia type 2(GD2)/Acromicric dysplasia(AD) induced by fibrillin 1(FBN1) gene mutation from one Chinese family.Methods:A Chinese pedigree of mild GD2/AD treated at the Pediatric Endocrinology Department at the First Affiliated Hospital of Sun Yat-sen University between August 2017 and May 2022 was collected. Whole-exome genetic sequencing of the FBN1 gene were performed to establish the diagnosis. Additionally, a literature review was further conducted.Results:In this family, among 13 individuals spanning three generations, there were 7 affected cases, including 1 adult female, 1 adult male, and 5 children. All individuals exhibited postnatal growth failure, severe disproportionate short stature, and lacked typical facial features. Exome sequencing and Sanger sequencing confirmed the presence of a heterozygous missense mutation c. 5099A>G(p.Tyr1700Cys) in exon 42 of the FBNI gene in 6 affected individuals(Ⅱ-1, Ⅲ-1 to Ⅲ-5), which was identified as a pathogenic mutation. This mutation was previously reported in a Chinese classical achondroplasia(AD) family. Based on comprehensive genetic analysis, clinical features, and multisystem evaluation, 3 cases were diagnosed with mild type 2 growth hormone deficiency(GD2), and 4 cases were diagnosed with mild AD. Recombinant human growth hormone(rhGH; 1.1-1.4 IU·kg -1·week -1) was applied to all the 5 children, and additional gonadotropin releasing hormone analogue(GnRHa) was administered to the 2 girls in late puberty, resulting in certain growth-promoting effect. Conclusions:The c. 5099A>G(p.Tyr1700Cys) mutation not only leads to the classical type of achondroplasia(AD) as reported in the literature but also causes the non-classical GD2 or AD(mild GD2/AD). Further research is warranted to investigate the long-term therapeutic effects of rhGH treatment.

Objective:To explore the prognostic predictive value of neutrophil/lymphocyte ratio (NLR) combined with prognostic nutritional index (PNI) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:Clinical data from 149 HBV-ACLF patients admitted to the infectious diseases Department of the General Hospital of Ningxia Medical University were retrospectively analyzed. Demographic data of the enrolled patients and the initial clinical-related data after admission were collected. Patients were divided into survival (93 cases) and death groups (56 cases) according to their prognostic condition 90 days after discharge. Demographic and clinical differences were compared between the two groups data. Receiver operating characteristic (ROC) curves were plotted to determine the optimal cutoff values for NLR and PNI in predicting the 90-day mortality rate of HBV-ACLF patients. The COX regression model was used to conduct univariate and multivariate analyses to investigate the correlation between NLR and PNI and the prognosis of HBV-ACLF patients. Kaplan-Meier survival analysis was used to explore the effects of NLR and PNI on the survival of HBV-ACLF patients.Results:The death group NLR was higher than that of the survival group, while the PNI was lower than that of the survival group, with a statistically significant difference. The area under the receiver operating characteristic curve (0.842, 95% CI: 0.779-0.906) showed patients with adverse prognosis assessed by NLR combined with PNI had a superior prognosis than that of the Model for End-Stage Liver Disease (MELD) and its combined serum sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores. COX regression analysis showed that NLR≥3.03 and MELD score were independent risk factors affecting the prognosis of HBV-ACLF patients. PNI > 36.13 was a protective factor for evaluating the prognosis of HBV-ACLF patients. Conclusion:NLR combined with PNI can enhance the prognostic predictive value of HBV-ACLF.
