ABSTRACT
Objective: To explore the correlation between alanine aminotransferase (ALT) trajectories and new-onset metabolic fatty liver disease (MAFLD) to provide a scientific basis for the prevention and treatment of MAFLD. Methods: The study cohort was composed of 3 553 subjects who met the inclusion criteria in the cohort study of the Henan physical examination population. According to the ALT levels of the subjects' physical examination from 2017-2019, three different ALT trajectory groups were determined by R LCTMtools, namely low-stable group, medium-stable group, and high-stable group. The incidence of MAFLD during physical examination in 2020 was followed up, the cumulative incidence rate in each group was calculated by product-limit method, and Cox proportional hazards regression model analyzed the correlation between different ALT trajectories and new-onset MAFLD. Results: The incidence rate of MAFLD parallelly increased with the increase of ALT locus, which was 6.93%, 15.42%, and 19.05%, respectively, and the difference was statistically significant (P<0.001). After adjusting for multiple confounding factors, such as gender, waist circumference, blood pressure, BMI, fasting blood sugar, and blood lipid by Cox proportional hazards regression model, the risks of MAFLD in ALT medium-stable and the high-stable group were still 1.422 times (95%CI:1.115-1.813) and 1.483 times (95%CI:1.040-2.114) of low-stable ALT group (P<0.05). Conclusions: The risk of MAFLD parallelly increases with the increase of ALT level in the normal long-term range. it is necessary to carry out the intervention for MAFLD with long-term average high value to avoid the progress of MAFLD disease to achieve the early prevention on MAFLD.

Objective To investigate the clinical value of multi-slice spiral CT(MSCT) in the diagnosis of mild digestive tract hemorrhage. Methods Thirty-five patients with mild gastrointestinal hemorrhage were examined by enhanced MSCT.CT signs were observed and compared with pathologic examination findings.Results Diseases in these 35 patients included gastric and duodenal ulcer and inflammation(n=4,11.4%),esophagogastric variceal rupture(n=7,20.0%),gastric carcinoma(n=3,8.6%),gastric stromal tumor(n=3,8.6%),gastric polyp(n=1,2.9%),colonic malignancy(n=5,14.2%),small intestinal stromal tumor(n=6,17.1%),rectal cancer(n=2,5.7%),intestinal Crohn disease(n=3,8.6%),and jejunum diverticulum combined with hemorrhage(n=1,2.9%).All of them were diagnosed by endoscopy of the digestive tract and confirmed by operation and pathology.The accuracy rate of CT was 100%.The coincidence rate of CT diagnosis was 97.1%.Conclusion MSCT is a promising technique in the localization,qualitative diagnosis,and clinical treatment of mild gastrointestinal hemorrhage.
ABSTRACT
Objective To understand the epidemiological characteristics and influential factors on internet addiction disorder (IAD) among first-grade junior students in Wuhan city. Methods An anonymous questionnaire survey was carried out on 1219 first-grade junior students through stratified cluster sampling in 4 middle schools in Wuhan city. Results The internet use rate (IUR) of first-grade junior students was 96.43% , with the average of primary surfer age as 8.93 + 1.95. The internet addiction tendency (IAT) rate and the IAD rate were 10.87% and 7.71% respectively. The IAT and the IAD detection rates among male students were significantly higher than in female students (χ~2=13.04,P<0.01). By ordinal logistic regression analysis, the relative factors mainly involved 6 aspects in IAD, including sex, poor academic performance, the surfer number of times, the surfer time, the surfer place and the surfer expense. Conclusion The prevalence rates of IAT and IAD were quite high in the first-grade junior students in Wuhan. School authorities, teachers and guardians should collaboratively working together to guide the students in using the network correctly, and to carry out effective interventions to reduce the incidence of internet addiction.
