Background With rising obesity rates and earlier hypertension onset among occupational populations, there is an urgent need to elucidate the long-term cardiovascular impacts of dynamic body weight patterns. Current evidence lacks trajectory modeling studies examining occupation-specific prevention strategies. Objective To investigate the association between long-term body mass index (BMI) trajectories and incident hypertension risk in Chinese working adults, and to examine occupation-specific heterogeneity in this relationship. Methods A dynamic sub-cohort of 4 413 occupational participants was constructed from ten survey waves (1991–2018) of the China Health and Nutrition Survey (CHNS). Eligible individuals had valid key BMI records at three or more independent follow-ups before the outcome event; the individual baseline was set as the year of their first participation in the survey. Group-based trajectory modeling (GBTM) was used to identify BMI change patterns. Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence interval (CI) for hypertension incidence across trajectory groups, with stratified analysis by occupational categories. Results Among 4413 occupational participants, 1441 incident hypertension cases were reported during the follow-up window. Three long-term BMI trajectories were identified: low-stable, moderate-slowly rising, and high-rising. In Model 3 with all selected confounders adjusted, compared with the low-stable group, the moderate-slowly rising group showed a significantly higher risk of incident hypertension (HR=1.28, 95%CI: 1.12, 1.45; P < 0.001), as did the high-increasing group (HR=1.80, 95%CI: 1.45, 2.23; P < 0.001). The stratified analyses revealed occupational differences in the association. Among agricultural workers, the moderate-slowly rising group (HR=1.35, 95%CI: 1.15, 1.57) and the high-rising group (HR=2.00, 95%CI: 1.50, 2.66) both exhibited significantly increased risks of hypertension (P<0.001). Conversely, among white-collar workers, an increased risk of hypertension was observed only in the high-rising group (HR=1.97, 95%CI: 1.23, 3.17; P<0.05). Conclusion Rapid BMI escalation constitutes a significant risk factor for incident hypertension in occupational populations. Targeted long-term weight monitoring and tailored interventions are recommended for high-risk occupations.

Objective To assay the salivary ANG-2 level of oral lichen planus(OLP)patients,and analyze its correlation with in-flammatory activity of OLP.Methods Eighty-nine OLP patients were included,and divided into four subgroups as non-erosive asymp-tomatic(NEA),non-erosive symptomatic(NES),minor-erosive(MIE)and major-erosive(MAE)groups.Fifteen healthy adults were recruited as controls.Whole unstimulated saliva was collected from each participant,and the salivary ANG-2 level was measured by chemiluminescence immunoassays(CLIA)for analysis.Normal oral mucosal tissue,non-erosive and erosive OLP tissues were collected to detect and analyze the expression of ANG-2 positive blood vessels by immunohistochemistry(IHC).Results The base-lines of age and gender between OLP and control groups showed no significant difference.Compared to controls,the salivary ANG-2 levels of OLP group,non-erosive and erosive OLP subgroups were significantly higher(P＜0.05),in which erosive OLP group was higher than non-erosive OLP group(P=0.022);NES subgroup was slightly higher than NEA(P=0.048),and there was no statistical significance between MIA and MEA subgroups(P=0.067).Spearman correlation analysis showed a positive correlation between sali-vary ANG-2 level and inflammation activity in OLP patients(r=0.314,P=0.003).The expression of ANG-2 in non-erosive OLP mu-cosal tissues slightly increased than normal oral mucosal tissue(P＞0.05),but there was no significant difference.The expression of ANG-2 in erosive OLP mucosal tissues significantly increased than normal oral mucosal tissue(P＜0.001)and non-erosive OLP group(P＜0.001).Conclusion There is a certain correlation between sali-vary ANG-2 level and inflammatory activity of OLP,indicating that salivary ANG-2 level is probable to be one of the inflammatory activity indicators to monitor the state-variation of OLP as a clinical non-inva-sive method.

Objective:To investigate the diagnostic value of non-high-density lipoprotein cholesterol (non-HDL-C),ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C), and triglyceride glucose index (TyG) on metabolic syndrome (MS) in adult women.Methods:This was a cross-sectional study. A total of 24 410 adult women who received health examination in health management center of the Affiliated Hospital of Southwest Medical University were selected from January 2019 to December 2021 as subjects. The subjects′ basic information, physical examination results, and laboratory examination data were collected retrospectively. The relationship between non-HDL-C, TG/HDL-C, TyG, and MS in adult women were examined using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) were calculated to evaluate the diagnostic value of each indicator for MS in adult women.Results:Among 24 410 adult females, 800 (3.3%) were found to have MS. After adjusting for age, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, blood uric acid, history of hypertension, history of diabetes, fatty liver, non HDL-C ( OR=1.608), TG/HDL-C ( OR=1.311), TyG ( OR=13.288) were all risk factors for MS in adult women. non-HDL-C, TG/HDL-C, and TyG, as well as their combined AUC of ROC, were 0.795 (95% CI: 0.742-0.776), 0.909 (95% CI: 0.902-0.917), 0.942 (95% CI: 0.937-0.948), and 0.944 (95% CI: 0.937-0.950), respectively. TyG had the highest diagnostic value for MS in adult women among the three indicators, the optimal cutoff value for TyG was 8.237, with a sensitivity of 93.5% and a specificity of 85.5%. Conclusion:non-HDL-C, TG/HDL-C, TyG, as well as their combination, all demonstrate good diagnostic value for MS in adult women.

Objective:To observe the efficacy of gentle moxibustion combined with Western medicine in treating rheumatoid arthritis(RA)due to damp heat affecting bones/joints to further certificate the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy". Methods:A total of 78 patients with RA due to damp heat affecting bones/joints were divided into an observation group and a control group using the random number table method,with 39 cases in each group.The control group was treated with regular Western medicine,on the basic of which the observation group was treated with additional gentle moxibustion.Patients in the observation group received gentle moxibustion therapy once a day for 8 weeks with a one-day rest every 2 weeks.The wrist circumference,wrist pain degree,skin color and temperature of the wrist,and range of dorsiflexion motion of the wrist in the two groups of patients were compared before and after treatment under the condition of safety observed. Results:The total effective rate in the observation group was 94.9%,which was higher than the result of 79.5%in the control group(P<0.05).Among the quantitative indicators of syndrome differentiation,the wrist circumference,pain degree,skin temperature,and range of dorsiflexion motion in both groups were significantly improved(P<0.01),and the improvements were more significant in the observation group than in the control group(P<0.05).The skin color of the wrist joint was improved in both groups after treatment(P<0.05),and there was no statistical significance in comparing the improvement of skin color and the occurrence of adverse reactions between the two groups(P>0.05). Conclusion:Compared with Western medicine treatment alone,the combination of gentle moxibustion and Western medicine treatment has significantly better treatment efficacy and shares high safety,which helps to prove the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy".

Objective:To investigate the value of Doppler ultrasonography in the determination of uterine artery data in early pregnancy for predicting gestational hypertension.Methods:Seventy patients with gestational hypertension treated in Jiashan First People′s Hospital from March 2018 to January 2020 were selected as the case group, and 70 healthy pregnant women who received routine prenatal examinations during the same period were selected as the control group. The differences of uterine artery data and pregnancy outcomes between the two groups at 11-13 +6 weeks of pregnancy were compared, and the value of each indicator in predicting gestational hypertension were analyzedby receiver operating characteristic (ROC) curve. Results:The uterine artery resistance index (RI), pulsatility index (PI), number of bilateral notches in the case group were higher than those in the control group: 0.54 ± 0.12 vs. 0.43 ± 0.08, 0.97 ± 0.36 vs. 0.69 ± 0.31, 12.86%(9/70) vs. 1.43%(1/70), and the differences were statistically significant ( P<0.05). The neonatal weight in the case group was lower than that in the control group: (2 912.38 ± 528.07) g vs. (3 487.39 ± 416.73) g; the intrauterine growth retardation rate, asphyxia rate and preterm birth rate in the case group were higher than those in the control group: 11.43%(8/70) vs. 1.43%(1/70), 8.57%(6/70) vs. 0, 15.71%(11/70) vs. 4.29%(3/70), the differences were statistically significant ( P<0.05). The analysis of ROC curve showed that the area under the curve(AUC) of PI in predicting gestational hypertension was the highest, and when AUC was 0.798, the sensitivity and specificity of PI in predicting gestational hypertension were 81.00% and 86.00% respectively. Conclusions:The uterine artery blood flow in pregnant women with gestational hypertension has been abnormal in early pregnancy (11-13 +6 weeks). The parameters of Doppler ultrasonography is used to predict gestational hypertension, and PI showes better predictive efficacy.

Epigenetics refers to the changes in gene expression level and function caused by non-genetic sequence changes.It can provide the time,location and mode of the genetic information for the execution of DNA sequences,including DNA methylation,histone modification,non-coding RNA and chromatin remodeling.Studies had shown that epigenetics plays an important role in the development of diabetic retinopathy (DR),and it had been found that epigenetic-related treatment regimens had a certain effect on the treatment of DR through animal experiments and in vitro experiments.It was benefit to regulate the development of diabetes and its complications by depth study of DNA methylation,histone modification,miRNA and metabolic memory.An understanding of changes in gene transcriptional mechanisms at the epigenetic level could help us to further study the prevention and control of diabetes and its complications,and to provide new ideas for treatment.
