Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

MethodsThe competence requirements of rehabilitation professionals of higher traditional TCM colleges and universities were analyzed using the theory and method of RCF. ResultsThe competency structure of TCM rehabilitation talents based on RCF was built, and the curriculum setting of TCM rehabilitation based on RCF was proposed. According to the characteristics of the educational environment of colleges and universities, a competency model suitable for undergraduate-level TCM rehabilitation major was established. ConclusionThe theory and methods of RCF are of great significance for the construction of competency-based education system of TCM rehabilitation major. Based on RCF, this study constructs the basic and practical curriculum system of TCM rehabilitation at the undergraduate level to promote the training of applied talents in TCM rehabilitation.

Objective: A longitudinal mediating model was designed to explore the relationship between sleep chronotype and depressive mood with stressful life events as the mediating variable, so as to provide reference basis for preventing depression in adolescents. Methods: From March (T1) to October (T2) 2022, the Munich Chronotype Questionnaire, and Adolescent Self-rating Life Events Checklist and Center for Epidemiologic Studies Depression Scale were administered in 1 251 middle school students in the first and second grades of a middle school in Meishan, Sichuan Province for a follow up study. Two wave of date on sleep time type, stressful life events, and depressive moods were collected. Results: At T1, the detection rate of depressive mood was 22.5% in adolescents but 27.0% at T2.At the same time point, there were significant positive correlations between chronotype, stressful life events and depressive mood ( r=0.06-0.69, P <0.05). Cross lagged model results showed that early sleep chronotype could significantly predict later depressive mood ( β=0.53, P <0.05), and early depressive mood could significantly predict later sleep chronotype ( β=0.01, P <0.01). Longitudinal mediation model analysis showed that T1 sleep chronotype not only directly affected T2 depressive mood (direct effect value=1.421, 95% CI =0.985- 1.858 , P <0.01), but also affect T2 depressive mood through the partial mediating effects of T2 stressful life events (indirect effect value=1.268, 95% CI =0.810-1.726, P <0.05). Although T1 depressive mood was a direct predictor of T2 sleep chronotype (direct effect value=0.025, 95% CI =0.017-0.032), it was not a direct predictor of T2 sleep chronotype by partial intermediate action of T2 stressful life events (indirect effect value=-0.001, 95% CI = -0.006- 0.004, P >0.05). Conclusions Sleep chronotype can not only directly predict depressive mood of adolescents, but also indirectly affect depressive mood of adolescents through the longitudinal mediating effect of stressful life events. To prevent depression and improve mental health in this population, adolescents should develop the habit of early sleep schedule, and improve their ability to cope with stressful life events.

Objective:To investigate the application value of pepsinogen, Helicobacter pylori combined with endoscopic Kimura-Takemoto classification in the diagnosis of early gastric cancer. Methods:Sixty patients with gastric cancer who received treatment in the Department of Gastroenterology, the First People's Hospital of Huzhou from January to June 2022 were included in the gastric cancer group. An additional 60 patients with benign gastric lesions (benign gastric lesion group) and 60 patients with precancerous lesions of the stomach (precancerous lesion group) were also included in this study. Serologic testing for pepsinogen and Helicobacter pylori antibody combined with endoscopic Kimura-Takemoto classification was performed to evaluate their application value in the diagnosis of early gastric cancer. Results:Compared with the benign gastric lesion and precancerous lesion groups, the pepsinogen I/pepsinogen II ratio was significantly lower, and the pepsinogen II level and Helicobacter pylori infection rate [71.67% (43/60)] were significantly higher in the gastric cancer group ( F = 108.14, 71.75, 38.43, χ2 = 6.89, all P < 0.05). Compared with the benign gastric lesion and precancerous lesion groups, the Kimura-Takenmoto classification in the gastric cancer group was significantly higher ( H = 38.91, P < 0.05). In the gastric cancer group, pepsinogen I level and pepsinogen I/pepsinogen II ratio decreased and pepsinogen II level increased with the increase of pathological stage ( F = 65.79, 5.66, 53.32, all P < 0.01). There was no significant difference in Helicobacter pylori infection rate between different stages of gastric cancer ( P < 0.05) in the gastric cancer group. There was no significant difference in Kimura-Takenmoto classification between different stages of gastric cancer (all P > 0.05) in the gastric cancer group. The area under the receiver operating characteristic curve plotted for evaluating pepsinogen I, pepsinogen II, and pepsinogen I/pepsinogen II ratio for diagnosis of gastric cancer was 0.865, 0.664, and 0.881, respectively. Conclusion:Serum pepsinogen, Helicobacter pylori combined with endoscopic Kimura-Takemoto classification can increase the diagnostic rate of early gastric cancer. The Kimura Takemoto classification is helpful for risk stratification in the endoscopic screening of gastric cancer, and its results are consistent with pepsinogen levels. The combined application is of a high application value.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.
