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 study the effect of orthodontic traction on the roots and periodontal soft and hard tissues of buried obstructed upper incisors. Methods: This study was reviewed and approved by the ethics committee, and informed consent was obtained from the patients. From January 2018 to December 2022, 40 patients who underwent orthodontic traction on impacted upper incisors were selected; those whose contralateral homonymous apical foramen was not developed were placed in group A (23 cases), and those whose contralateral homonymous apical foramen was developed were placed in group B (17 cases). Software was used to measure the root length of the impacted upper incisors in groups A and B on cone beam CT (CBCT) images before and after traction and compare the changes in alveolar bone (alveolar bone width, labral bone plate thickness, and horizontal height of alveolar bone) and keratinized gingival width between each impacted upper incisor and the corresponding contralateral tooth immediately and one year after traction Results: The root length of the impacted upper incisors increased after traction compared to before traction (P<0.05). The width of the alveolar bone at the completion of traction in group A was similar to that of the contralateral homonymous tooth (P>0.05), whereas the width of the alveolar bone at the completion of traction in group B did not reach that of the contralateral homonymous tooth, with a significant difference in width (P<0.05). Neither the labial bone plate height or width in group A or B reached that of the contralateral homonymous tooth after traction (P<0.05). The keratinized gingival width on the affected side was also significantly smaller than that on the contralateral side (P<0.05), but it was increased significantly in group A at the one-year follow-up visit (P<0.05). Conclusion Tooth traction is conducive to impacted upper incisor root growth, alveolar bone reconstruction and keratinized gingival growth but cannot produce complete symmetry with respect to the contralateral side.

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.

Objective:To investigate the correlation between the trajectory of triglyceride-glucose index multiplied by body mass index (TyG×BMI) and the incidence of new-onset non-alcoholic fatty liver disease (NAFLD).Methods:It was a retrospective cohort study. A total of 2 304 subjects who underwent health examinations at the Health Management Center of the First Affiliated Hospital of Zhengzhou University from 2017 to 2019 were included as the study population. Based on the TyG×BMI values from the health examinations, a latent class modeling approach was used to determine four distinct TyG×BMI trajectory groups: low-stable, moderate-stable, high-stable, and extremely high-stable group. The incidence of NAFLD was followed-up during the 2020 and 2021 health examinations for each group. The differences in NAFLD incidence among different TyG×BMI trajectory groups were compared using the log-rank test, and the correlation between different TyG×BMI trajectories and the incidence of new-onset NAFLD was analyzed using Cox proportional hazards regression models.Results:The incidence of NAFLD increased with the elevation of TyG×BMI trajectories. The cumulative incidence rates of NAFLD for the low-stable, moderate-stable, high-stable, and extremely high-stable groups was 13.00%, 16.70%, 20.10% and 26.60%, respectively, with statistically significant differences ( χ2=35.155, P<0.01). Compared with the low-stable group, the high-stable and extremely high-stable groups had higher risks of NAFLD (HRs for high-stable group was 1.564, 1.428, 1.426, 1.289, respectively; HRs for extremely high-stable group was 2.121, 1.670, 1.659, 1.607, respectively; all P<0.05). After adjusting for various confounding factors such as gender, waist circumference, BMI, blood glucose, blood lipids and liver function in model 4, the risks of NAFLD for the high-stable and extremely high-stable groups were still 1.389 and 1.607 times higher than that in the low-stable group (95% CIs: 1.035-1.864, 1.207-2.140). Conclusion:The risk of NAFLD increases with the elevation of TyG×BMI trajectories, suggesting that TyG×BMI can serve as a predictive index for NAFLD.

Objective:To investigate the mediation effect of triglyceride glucose index(TyG) on the relation between thyroid nodules and visceral fat area.Methods:A total of 9 324 individuals at the Health Management Center of the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2021 were selected, and the basic information, biochemical indicators, color ultrasound of thyroid were also collected. According to the cut-off value of visceral fat area(VFA) of 100 cm 2 and body mass index(BMI) of 24 kg/m 2, they were divided into four groups: VFA(-)BMI(-), VFA(-)BMI(+ ), VFA(+ )BMI(-), and VFA(+ )BMI(+ ). Chi-square test was used to compare the incidence rate among the four groups, and multivariate logistic regression analysis to indentify influencing factors. TyG and VFA were quartiled, and multivariate logistic regression analysis was used to explore the effects of TyG and VFA on thyroid nodules. The regression coefficient test was used to analyze whether TyG mediated the association between VFA and thyroid nodules. Results:Multivariate logistic regression analysis revealed that compared with VFA(-)BMI(-) group, the VFA(+ )BMI(-) group had the highest risk of thyroid nodules( OR=1.283, 95% CI 1.064-1.546, P=0.009), followed by VFA(+ )BMI(+ ) group( OR=1.245, 95% CI 1.028-1.508, P=0.025). When using TyG and VFA Q1 group as reference, the Q4 group showed an increased risk of thyroid nodule by 1.584 times(95% CI 1.208-2.077, P=0.001) and 1.573 times(95% CI 1.249-1.982, P<0.001), respectively. Mediation analysis indicated that VFA had a direct impact on the incidence rate of thyroid nodules( β=0.162, 95% CI 0.140-0.186, P<0.001). TyG partially mediated the effect of VFA on the incidence rate of thyroid nodules( β=0.103, 95% CI 0.087-0.121, P<0.001), accounting for 38.87% of the total effect. Conclusions:VFA is an independent risk factor for thyroid nodules regardless of BMI. Among individuals with visceral obesity but normal BMI, the incidence rate of thyroid nodules was the highest. In addition, TyG partially mediates the risk of thyroid nodules in patients with visceral obesity. The evaluation of visceral obesity might be of great significance in the early screening and prevention of thyroid nodules.

Objective:To explore the relationship between the long-term dynamic change in alanine aminotransferase(ALT) level and metabolic associated fatty liver disease(MAFLD).Methods:A retrospective study was conducted on 6 864 subjects who underwent four consecutive physical examinations from 2017 to 2020 in a cohort study of physical examination population in Henan Province. The relation between ALT level and the shift of MAFLD risk was analyzed using a multi-state Markov model, and the bidirectional relationship between ALT level and MAFLD was explored using a random intercept cross-lagged model.Results:Multi-state Markov model after adjusting for confounding factors showed that the risk of MAFLD in ALT Q2, Q3, Q4 group was gradually higher than that in Q1 group; Compared with health status, non-alcoholic fatty liver disease and MAFLD status gradually increased the risk of ALT shifting from normal to abnormal. The random intercept cross-lagged model after adjusting for confounding factors showed that there was a significant positive bidirectional relationship between MAFLD and ALT level. The cross-lag effect of MAFLD→ALT level was 0.083(95% CI 0.078-0.087), and the cross-lag effect of ALT→MAFLD was 0.044(95% CI 0.039-0.050). And with the extension of time, the cross-lag effect gradually decreased. Conclusions:There is a significant bidirectional relationship between the long-term dynamic change of ALT level and MAFLD. The occurrence of MAFLD is more likely to increase the risk of elevated ALT level, emphasizing the need for enhanced early prevention and treatment of MAFLD.

Objective:To investigate the correlation between fasting plasma glucose (FPG) and new-onset carotid plaque through latent class trajectory models.Methods:A total of 953 observation objects came from the first affiliated hospital of Zhengzhou University in accordance with the inclusion criteria. According to the FPG values of the observed subjects during the annual physical examination from January 2017 to December 2019, the following four different FPG trajectories groups were determined by latent class trajectory modelling tools: the low-stable group, the medium stable group, the medium-high stable group, and the high stable group. Carotid plaque incidence in each group was followed up in 2020 to compare the differences of the cumulative incidences of the four groups. The Cox proportional risk regression model was used to analyze the correlation between different FPG trajectories and new-onset carotid plaque.Results:The incidence of carotid plaque increased with the increase of FPG trajectories by 11.13%, 19.70%, 23.44%, 23.81%, respectively, with significance ( P<0.001). After adjusting gender, age, BMI and other confounding factors with the cox proportional risk regression model, the risk of carotid plaque in the FPG medium stable group, medium and high stable group, high-stable group was still 1.895 (95% CI: 1.296-2.769), 2.273 (95% CI: 1.241-4.161), 2.527 (95% CI: 1.219-5.241) times of the low stable group (all P<0.05). Conclusion:The long-term high FPG levels are independent risk factors for the incidence of carotid plaque, and controlling FPG at a low level steadily can reduce the risk of carotid plaque.

Methods A total of 130 patients with CSA who met the inclusion criteria were andomly divided into 2 groups, 65 patients in each group. The observation group was treated with heat-sensitive oxibustion combined with blood-letting, and the control group was treated with conventional acupuncture. oth groups were treated for 14 days. The Transcranial Doppler was used to monitor the peak velocity of ystolic (Vs) of the intracranial vertebral artery and basilar artery, the peak velocity of diastolic (Vd) and the esistante index (RI). The whole blood viscosity (RBV), plasma specific viscosity (RPV), the hematocrit HCT) and the erythrocyte sedimentation rate (ESR) were detected and the clinical efficacy was evaluated.Results The total effective rate was 93.9% (61/65) in the observation group and 80.0% (52/65) in the control roup. The difference between the two groups was statistically significant (χ2=5.482, P=0.019). After treatment,the RBV, the RPV, HCT and ESR in the observation group were significantly lower than the control group. The Vs on the left side of the vertebral artery in the observation group was significantly higher than that in the control group (t=2.087, P=0.039), and the Vs and Vd in the right vertebral artery were significantly higher than the control group (t values were 3.505, 3.161, respectively, all Ps<0.01). The RI of the observation group was significantly lower than the control group (t=2.425, P=0.017). The Vs and Vd of the basilar artery in the observation group were significantly higher than the control group (t values were 2.716, 4.748, all Ps<0.01), and the RI was significantly lower than the control group (t=3.299, P=0.001). Conclusions Moxibustion combined with bloodletting can relieve the symptoms of CSA patients, improve the vertebrobasilar blood supply and improve clinical efficacy.

Objective To investigate the incidence and risk factors of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture. Methods Live born infants, including those diagnosed with neonatal asphyxia, were recruited from 16 different hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture from January to December of 2016. The 16 hospitals included four grade A tertiary hospitals (three general hospitals and one traditional Chinese medicine hospital) and 12 grade A secondary hospitals (eight general hospitals, one maternal and child health hospital and three traditional Chinese medicine hospitals). A retrospective investigation was conducted using questionnaire to analyze the basic information, perinatal risk factors and prognosis of those infants. Chi-square test was used for statistical analysis. Results Among 22 294 recruited live born infants, 733 (3.29%) were diagnosed with neonatal asphyxia on discharge, including 627 (85.54%) mild cases and 106 (14.46%) severe cases. And neonatal asphyxia resulted in deaths of 27 cases (3.68%). The risk factors for neonatal asphyxia included multiple pregnancy, pregnancy conceived with assisted reproductive technology, premature infant, low birth weight infant, fetal malposition, congenital malformation, male infant, born during transfer, mother of Tujia nationality, low educational level (primary school or lower), living in rural area, the number of antenatal visits ≤3, history of early threatened abortion, anemia in pregnancy, hypertensive disorders of pregnancy, chorioamnionitis, abnormal pregnancy history and abnormality of umbilical cord, amniotic fluid or placenta. Conclusions The incidence of neonatal asphyxia in Enshi area is obviously higher than the national average. The main risk factors for neonatal asphyxia in this area are related to maternal background and the living condition of the mother during pregnancy, delivery as well as the newborn at birth.
