Objective:To evaluate the association between triglyceride-glucose(TyG) index level, their variability, and the risk of incident hyperuricemia(HUA).Methods:A total of 1 583 cases with good compliance who underwent follow-up at the health examination center of a tertiary hospital physical in Zhengzhou were enrolled. The TyG index mean(TyG-mean) and variability indexes, including standard deviation(TyG-SD), coefficient of variation(TyG-CV), and adjusted standard deviation(adj-TyG-SD), were calculated based on TyG index values from three consecutive annual health check-ups. Cox proportional risk regression model was used to assess the relationship between the variability of TyG index and the risk of new-onset HUA; the dose-response relationship between different TyG indexes and HUA was examined using restricted cubic spline(RCS). Results:After a 3-year follow-up, 146 participants developed incident HUA. Both TyG-mean and TyG index variability indicators were significantly higher in the HUA group compared to the non-HUA group( P<0.05). After adjusting for multiple confounders, each standard deviation σincrease in TyG-SD, TyG-CV, and adj-TyG-SD was associated with a 1.23-fold(95% CI 1.06-1.43), 1.22-fold(95% CI 1.05-1.42), and 1.26-fold(95% CI 1.08-1.45) higher risk of incident HUA, respectively. RCS analysis revealed a nonlinear association between adj-TyG-SD and HUA risk( P<0.05), with a critical threshold of 0.55 at a hazard ratio( HR) of 1. Conclusions:Increased TyG index variability is associated with a higher risk of incident HUA, with adj-TyG-SD showing the strongest correlation with HUA risk.

Objective    To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods    A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results    A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion    For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.

Objective:To explore the potential correlation between cumulative pulse pressure (cumPP) level and metabolic syndrome (MetS), and to provide insights for MetS management.Methods:A total of 3 968 subjects who underwent health checkup were selected to form a research cohort, and the data were categorized into three groups based on the tertiles of cumPP levels. Cox proportional hazards regression model was employed to analyze the association between different cumPP levels and the incidence of new-onset MetS. Results:The risk of MetS increased with the increased tiers of the cumPP levels (2.5%, 4.3%, and 4.6%, Ptrend<0.001) during the median follow-up period of 2.16 years. Spearman rank correlation analysis showed that cumPP was positively correlated with waist circumference, systolic blood pressure, diastolic blood pressure and fasting plasma glucose (all P<0.05). The Cox proportional hazards regression adjusted model showed that the risk of MetS in Q2 and Q3 was higher than that in Q1 in the total population, and the same results were observed in males (all P<0.05), while there was no statistical significance in females. Model 3 of the total population adjusted for a variety of confounding factors displayed a higher risk of MetS in Q3 compared with that in Q1[1.654 (95% CI 1.272-2.151) ]. When stratified by sex, and the risk of MetS in Q3 was 1.665 times higher than that in Q1 (95% CI 1.245-2.227), while there was no statistically significant risk in female. According to the visual nomogram of independent risk factors screened by multivariate analysis based on Cox proportional hazards regression model, the incidence of MetS at 1 year, 2 years, and 3 years was 0.18%, 3.97% and 7.39%, respectively. In addition, the dose-response curve was plotted according to cumPP, suggesting that the risk of MetS gradually increased with the increase of cumPP in the total population. Subgroup analyses based on baseline systolic blood pressure levels showed that higher cumPP levels were associated with a higher risk of developing MetS, regardless of whether systolic blood pressure was abnormal. Conclusions:Elevated cumPP levels is significantly related to the incidence of new-onset MetS. Maintaining pulse pressure within an appropriate range over long term is crucial for the management of MetS.

Objective:To explore the association between glutamyl transpeptidase (GGT) trajectories and new-onset metabolic syndrome to provide insights for the prevention and treatment of metabolic syndrome.Methods:A total of 3 209 subjects who met the inclusion criteria were enrolled in the study cohort of physical examination population. The GGT levels before follow-up were classified by R LCTMtools program into 3 GGT trajectory groups: low-stable group, medium-stable group and high-stable group. Cox proportional hazards regression model was used to analyze the correlation between different GGT trajectories and new-onset metabolic syndrome.Results:At the end of follow-up in 2020, the cumulative incidence of metabolic syndrome was 7.0%, and the incidence of metabolic syndrome in the low-stable group, medium-stable group and high-stable group were 3.9%, 11.4%, and 15.0%, respectively, showing a growth trend ( P<0.001). After adjusting for multiple confounding factors by Cox proportional hazards regression model, the risk of metabolic syndrome in medium-stable group and high-stable group increased in the total population. The hazard ratios (95% CI)for the high stable group in males and the medium-stable group in females were 1.67(1.07-2.60) and 3.29(1.14-9.53), respectively, compared with their respective low-stable group. Conclusion:Elevated longitudinal trajectory of GGT is a risk factor for new-onset metabolic syndrome, the risk of metabolic syndrome in the total population increased with the increase of long-term GGT level. It is recommended to maintain the long-term level of GGT at about 28 U/L in males and 14 U/L in females, respectively, to achieve the goal of early prevention of metabolic syndrome.

In recent years, the artificial intelligence machine learning and deep learning technology have made leap progress. Using clinical decision support system for auxiliary diagnosis and treatment is the inevitable developing trend of wisdom medical. Clinicians tend to ignore the interpretability of models while pursuing its high accuracy, which leads to the lack of trust of users and hamper the application of clinical decision support system. From the perspective of explainable artificial intelligence, the authors make some preliminary exploration on the construction of clinical decision support system in the field of liver disease. While pursuing high accuracy of the model, the data governance techniques, intrinsic interpretability models, post-hoc visualization of complex models, design of human-computer interactions, providing knowledge map based on clinical guidelines and data sources are used to endow the system with interpretability.
