Objective To analyze the prevalence characteristics and influencing factors of metabolic syndrome (MS) in people aged 35-75 years in Hubei Province. Methods The follow-up data from 2016 to 2022 in the early screening and comprehensive intervention project for high-risk cardiovascular population in Hubei Province were collected. SAS 9.4 software was used to conduct 2-test and multivariate logistic regression to analyze the prevalence of MS and its influencing factors. Results Among the 89 199 subjects, 24 757 were affected by MS, with a prevalence rate of 27.75% and a standardized rate of 23.55%. Among the various components of MS, the prevalence of abnormal blood pressure was the highest, at 70.88%, and the standardized rate was 59.32%. Secondly, abnormal blood glucose was 36.26%, and the standardized rate was 30.04%. Central obesity was 33.12%, and the standardized rate was 30.28%. Hypertriglyceridemia was 32.90%, and the standardized prevalence rate was 32.70%. The rate of low HDL-C syndrome was 10.25%, and the standardized rate was 11.67%. The results of multivariate logistic regression analysis showed that the risk of MS increased with age, and the risk of MS in urban residents was lower than that in rural residents (OR=0.835, 95%CI: 0.77-0.886). Administrative and professional workers had a higher risk of MS than farmers (OR=1.313, 95%CI:1.194-1.445). Overweight, obesity, central obesity, history of self-reported hypertension, history of self-reported diabetes, and history of self-reported dyslipidemia were associated with a higher risk of MS, and the differences were statistically significant (P < 0.001). Conclusion The prevalence of MS is high in people aged 35-75 years in Hubei Province. On the basis of comprehensive intervention, focus monitoring should be strengthened to control the risk factors of MS and reduce the risk of cardiovascular and cerebrovascular diseases.

Objective To explore the effect of sequential therapy with butylphthalide on the risk of post-stroke epilepsy(PSE)in patients with cerebral infarction.Methods The clinical data of patients with cerebral infarction hospitalized in Langfang People's Hospital from October,2016 to October,2022 were selected and analyzed.Patients receiving butylphthalide sequential treatment were included in the butylphthalide group,patients who were hospitalized at the same time with matching gender,age(±5 years),basic disease,clinical drug treatment scheme and follow-up period but did not receive butylphthalide treatment were included in the control group.The general clinical data,laboratory examination results on admission,and incidence of PSE in the two groups were compared,and multivariate Logistic regression was used to analyze the correlation between sequential therapy with butylphthalide and PSE occurrence in patients with cerebral infarction.Results A total of 1,200 patients were included,with 600 patients in each group.There was no significant difference in general clinical data such as sex,age,complications and living habits between the two groups(P＞0.05).There were no significant differences between the two groups in the patients distribution of TOAST classification,NIHSS score(P＞0.05).The incidence of PSE in butylphthalide group was significantly lower than that in control group(4.17％vs.7.83％,P＜0.05).The application of sequential treatment with butylphthalide was a protective factor for PSE occurrence in patients with cerebral infarction[OR=0.352,95％CI(0.151,0.821),P=0.016].Conclusion Sequential treatment with butylphthalide can reduce the risk of post-stroke epilepsy in patients with cerebral infarction.

BACKGROUND:The pathogenesis of osteoporosis is closely related to the immune system.A comprehensive and in-depth study of the relationship between immunity and osteoporosis is crucial for understanding and treating the disease.OBJECTIVE:To investigate the role of immune cells in osteoporosis using single-cell sequencing technology.METHODS:Femoral head tissue samples from osteoporosis and non-osteoporosis patients were downloaded from GEO database and analyzed using single-cell sequencing.Data analysis,including cell clustering,functional enrichment,pseudotime trajectory,and cell interaction analyses,was performed using R4.3.0 and software packages such as Seurat v.4.3,monocle(2.28.0),and CellChat.The femoral head tissues of patients with femoral neck fracture who underwent artificial hip replacement surgery were obtained,including two cases of osteoporosis patients and two cases of non-osteoporosis patients.Immunohistochemical staining was used to detect the protein expression of CCL13 and CCL18.qPCR was used to detect the immunoglobulin heavy constant γ-4,immunoglobulin λ constant 3,human class Ⅱ major histocompatibility complex DRβ1,and CD83 mRNA expression.Western blot was used to detect the protein expression of receptor-type tyrosine protein phosphatase C,CD22,and CD99.RESULTS AND CONCLUSION:Transcriptomic analysis identified 10 cell clusters,including osteoclasts,myeloid cells,T cells,osteoblasts,macrophages,monocytes,erythrocytes,B cells,bone marrow mesenchymal stem cells,and mast cells.There was an increase in the ratio of osteoclasts to T cells and a decrease in the ratio of osteoblasts to B cells in the femoral head tissue of the osteoporosis group.Among the B-cell subpopulations,the proportion of B-cells of taxa 1,3(BC1,BC3)in the femoral head tissue of the osteoporosis group was higher than that of the non-osteoporosis group,and the proportion of B-cells of taxa 2(BC2)was less than that of the non-osteoporosis group.BC1 was enriched significantly for labels such as regulation of adaptive immune response,somatic recombination of immune receptors,and modulation of lymphocyte-mediated immunity,while BC3 was enriched significantly for labels such as regulation of immunoglobulin production,response to type Ⅱ interferon,apoptotic processes involving cysteine endopeptidases,and cytotoxicity.The communication intensity between B-cell subtype BC1 and osteoblasts in the femoral head tissue of the osteoporosis group was higher than that of the non-osteoporosis group,while the communication intensity between BC3 and BC1 was also increased.The communication between BC3 and BC1 was significantly enriched in the CD22-receptor-type tyrosine protein phosphatase C pathway;the communication between BC1 and osteoblasts was mainly enriched in the CD99-CD99 pathway;and the communication between BC3 and osteoblasts was also highly enriched in the CD99-CD99 pathway.Protein expression of CCL13,CCL18,receptor-type tyrosine protein phosphatase C,CD22,CD99,immunoglobulin heavy constant γ-4,immunoglobulin λ constant 3,human class Ⅱ major histocompatibility complex DRβ1,and CD83 mRNA were higher in femoral tissues of the osteoporosis group than those of the non-osteoporosis group(P＜0.05).To conclude,specific B cell subpopulations can influence the differentiation and apoptosis of osteoblasts in the femoral tissue of osteoporosis patients.

Objective To propose and validate a decomposition method based on half-projection reconstruction for dual-energy cone beam CT(DE CBCT),thereby providing a potentially feasible low-dose imaging solution for anatomical monitoring and dose reconstruction optimization in adaptive radiotherapy.Methods Dual-energy scans were performed on a Gammex phantom using the on-board kilovoltage CBCT system of a VitalBeam accelerator at acquisition frame rates of 15 and 7 frames per second(f/s).Images were reconstructed from the projection data,and dual-energy decomposition was applied to the 7 f/s dual-energy images to derive relative electron density(RED)and stopping power ratio(SPR)using weighted formulas and empirical functions,followed by accuracy evaluation.Additionally,the weighted CT dose index was calculated for different scanning parameters.Results Dual-energy decomposition effectively suppressed image artifacts,with RED and SPR errors remaining below 2.82%and 2.56%,respectively.Compared with the traditional dual-scan method which required high-and low-energy acquisitions,the weighted CT dose index of the half-projection DE CBCT was reduced by 11.60 mGy(a 52.90%reduction).Furthermore,it was 2.58 mGy lower than the dose of the full-projection high-energy CBCT alone(a 19.98%reduction)and only 1.31 mGy higher than that of the low-energy CBCT(a 14.52%increase).Conclusion The proposed method effectively suppresses image artifacts while maintaining high accuracy in RED and SPR under low radiation dose conditions,demonstrating its potential value for scenarios requiring frequent image guidance,such as adaptive radiotherapy.

Objective To evaluate the feasibility and effectiveness of 3D digital holographic imaging combined with intraoperative navigation technology in the context of partial nephrectomy.Methods A total of 46 patients who underwent laparoscopic partial nephrectomy in the Department of Urology at the Second People's Hospital of Hefei City between June 2023 and January 2025 were randomly assigned to either the experimental group or the control group.The experimental group(n=23)utilized preoperative planning and intraoperative real-time navigation based on 3D digital holographic imaging,whereas the control group(n=23)relied on preoperative planning using optimized two-dimensional images obtained via contrast-enhanced CT and MRI scans.Preoperative data—including gender,age,body mass index(BMI),tumor diameter,and RENAL score—were collected.Intra-operative parameters such as total operative time,warm ischemia time,intraoperative blood loss,hemoglobin levels,postoperative hospitalization duration,and time to drain removal were recorded.Renal function changes were assessed by comparing serum creatinine levels and estimated glomerular filtration rates(eGFR)before surgery and one month post-surgery.Additionally,the incidence of intraoperative complications—particularly injury to the renal collecting system—and postoperative complications—including positive surgical margins,bleeding,subcutaneous emphysema,and urinary fistula—was analyzed.Results In this study,holographic images were successfully reconstructed for 23 patients with renal tumors in the experimental group.Each anatomical structure—including the kidney and tumor lesions,collecting system,renal arteries and veins,adrenal glands,and inferior vena cava—was color-coded to enable intuitive visualization.These images were used for preoperative planning and provided real-time spatial orientation to accurately locate and guide resection of the tumor during surgery.In the control group,23 patients underwent preoperative planning based on contrast-enhanced CT and MRI scans acquired using optimized parameters.All 46 patients underwent laparoscopic partial nephrectomy performed by the same qualified surgeon,and postoperative pathological analysis confirmed renal tumors,including 27 cases of clear cell carcinoma,7 cases of chromophobe cell carcinoma,5 cases of papillary cell carcinoma,2 cases of sarcomatoid carcinoma,and 5 cases of angiomyolipoma.No significant differences were observed in baseline clinical characteristics(including age,body mass index,tumor diameter,and RENAL score)between the two groups(P＞0.05).The experimental group showed significantly lower values in total operative time,warm ischemia time,intraoperative blood loss,pre-to postoperative hemoglobin changes,and pre-surgical to one-month post-surgical creatinine changes compared to the control group(P＜0.01).Additionally,the experimental group exhibited smaller changes in hospitalization duration,time to drain removal,and glomerular filtration rate from preoperative to one month post-surgery;however,these differences were not statistically significant(P=0.175,P=0.331,and P=0.273).There were no intraop-erative complications or damage to the collecting system in either the experimental or control groups.Postopera-tively,the control group experienced one case of positive surgical margin,one case of hemorrhage,and one case of subcutaneous emphysema.No statistically significant differences were observed between the groups(P＞0.05).Conclusions 3D digital holographic imaging combined with intraoperative navigation technology,based on the fusion of MRI and CT data,facilitates preoperative planning and precise intraoperative guidance.This approach helps reduce operative time,preserve renal function,and lower perioperative risks while ensuring therapeutic efficacy.

Background The association between occupational physical activity (OPA) and cardiometabolic risk factors remains controversial, potentially due to differences in the associations between OPA and various cardiometabolic indicators, as well as the lack of a clearly defined optimal OPA range for multiple-indicator synergistic benefits. Objective To investigate the relationship between OPA and cardiometabolic risk factors in individuals at high risk of cardiovascular disease (CVD) in Hubei Province, and to explore an optimal OPA range for multi-indicator improvements. Methods Data were derived from the Hubei Province dataset of the China Health Evaluation And Risk Reduction Through Nationwide Teamwork from 2015 to 2023, including 19028 high-risk CVD individuals. OPA (metabolic equivalent·h·d⁻¹, MET·h·d⁻¹) was assessed using the China Kadoorie Biobank physical activity questionnaire, anthropometric measurements (height, weight, waist circumference) and cardiometabolic indicators (blood pressure, fasting blood glucose, lipid profiles) were measured. Multivariate logistic regression was used to analyze the association between logOPA quartiles (Q1-Q4) and abnormal cardiometabolic indicators, while restricted cubic spline (RCS) models were employed to explore their dose-response relationships. Subgroup and interaction analyses were also conducted by gender. Results The median OPA of all participants was 12.86 MET·h·d⁻¹ (male: 14.40 MET·h·d⁻¹, female: 11.14 MET·h·d⁻¹). After adjusting for confounders, compared with the Q1 group, logOPA in the Q4 group was associated with 20% (OR=0.80, 95%CI: 0.72, 0.89), 14% (OR=0.86, 95%CI: 0.78, 0.96), and 13% (OR=0.87, 95%CI: 0.79, 0.95) reduction in the risk of abdominal obesity, low high-density lipoprotein cholesterol (HDL-C), and metabolic syndrome (MS), respectively, and 33% (OR=1.33, 95%CI: 1.18, 1.49), 33% (OR=1.33, 95%CI: 1.18, 1.50), and 38% (OR=1.38, 95%CI: 1.21, 1.57) increase in the risk of high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), and high non-HDL-C, respectively. Similar trends were observed in males and females, with significant positive associations of logOPA with high TC and high non-HDL-C in males (P_interaction<0.05). The risk of low HDL-C decreased rapidly when logOPA was more than 2.213 (OPA>9.14 MET·h·d⁻¹), showing an inverted L-shaped trend. The risk of high TC, high LDL-C, and high non-HDL-C increased beyond logOPA thresholds of 3.244, 2.476, and 3.377 (OPA >25.64, 11.89, and 29.28 MET·h·d⁻¹), respectively, showing a J-shaped trend. However, logOPA exhibited a U-shaped nonlinear dose-response relationship with blood pressure and fasting blood glucose abnormalities (P_non-linear<0.05) , with minimal risks at logOPA 2.969 and 2.372 (OPA of 19.47 and 10.72 MET·h·d⁻¹). Conclusion OPA exhibits heterogeneous dose-response patterns across cardiometabolic indicators. Integrating the inverted L-, J-, and U-shaped association patterns, we suggest an optimal OPA range of 9.14−25.64 MET·h·d⁻¹ for multiple cardiometabolic indicators in total individuals at high-risk of CVD, with ranges of 9.61−31.34 MET·h·d⁻¹ for males and 8.97−22.87 MET·h·d⁻¹ for females. These findings provide critical evidence for developing OPA interventions strategies targeting high-risk population for CVD.
