ABSTRACT
Objective@#To investigate the association of Internet gaming disorder (IGD) and sleep quality in adolescents of Xi an, thereby providing theoretical evidence for prevention of IGD and improvement of sleep quality of adolescents.@*Methods@#A total of 1 181 adolescents from 3 middle schools of Xi an were randomly selected between August, 2019 and February, 2020. These adolescents were assessed by a series of questionnaires, including basic information questionnaire, IGD and Insomnia Severity Index (ISI). Univariate analysis and multivariate Logistic regression model were used to evaluate the association between IGD and insomnia.@*Results@#Among 929 junior middle school students who participated in online games and the IGD Diagnostic Questionnaire was filled out in the past 12 months, the prevalence of IGD was 20.0%(186). Univariate analyses indicated that gender,whether single family, whether they living with their parents, whether they were addicted to online games, whether they could control the time of online games, and the severity of insomnia influenced IGD ( χ 2=17.11, 8.33, 202.92, 91.23, 29.06, P <0.05). The multivariate Logistic regression of the total population showed that participating in online games was not associated with the severity of insomnia ( OR = 1.62 , 95% CI =0.92-0.85, P >0.05). The people who participated in online games in the past 12 monthsthe severity of insomnia was positively correlated with the risk of IGD ( OR =3.56，95% CI =1.92-6.61, P <0.01).@*Conclusion@#Internet gaming disorder become a severe situation in the middle school students. The severity of insomnia might become the risk factor of IGD, so social should pay more attention to the prevention of internet addiction.

ABSTRACT
OBJECTIVE: To evaluate the spontaneous brain activity alterations in liver transplantation (LT) recipients using resting-state functional MRI. MATERIALS AND METHODS: Twenty cirrhotic patients as transplant candidates and 25 healthy controls (HCs) were included in this study. All patients repeated the MRI study one month after LT. Amplitude of low-frequency fluctuation (ALFF) values were compared between cirrhotic patients (both pre- and post-LT) and HCs as well as between the pre- and post-LT groups. The relationship between ALFF changes and venous blood ammonia levels and neuropsychological tests were investigated using Pearson's correlation analysis. RESULTS: In the cirrhotic patients, decreased ALFF in the vision-related regions (left lingual gyrus and calcarine), sensorimotor-related regions (left postcentral gyrus and middle cingulate cortex), and the default-mode network (bilateral precuneus and left inferior parietal lobule) were restored, and the increased ALFF in the temporal and frontal lobe improved in the early period after LT. The ALFF decreases persisted in the right supplementary motor area, inferior parietal lobule, and calcarine. The ALFF changes in the right precuneus were negatively correlated with changes in number connection test-A scores (r = 0.507, p < 0.05). CONCLUSION: LT improved spontaneous brain activity and the results for associated cognition tests. However, decreased ALFF in some areas persisted, and new-onset abnormal ALFF were possible, indicating that complete cognitive function recovery may need more time.

<p><b>OBJECTIVE</b>To investigate the relationship between polymorphism of Ghrelin gene and serum levels of lipoprotein in Han Chinese with or without coronary heart disease (CHD) risk factors.</p><p><b>METHODS</b>PCR restriction fragment length polymorphism assay was used to detect the distribution of genotypes of Ghrelin gene in 225 Han Chinese (40 to 69 years-old) with CHD risk factors, 78 subjects without CHD risk factors served as normal controls. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein (VLDL) were measured to analyze the relationship with the polymorphism of Ghrelin gene.</p><p><b>RESULTS</b>Ghrelin genotype frequencies of AA, AG, GG (0.975, 0.025, 0.00 in control group and 0.956, 0.040, 0.004 in the high-risk group, all P > 0.05) as well as the allele frequencies of A, G (0.987, 0.013 in control group and 0.976, 0.024 in the high-risk group, all P > 0.05) were similar between the groups. HDL-C levels of the Arg/Gln carriers were significantly lower than those of Arg/Arg carriers in control group and in the high-risk group (all P < 0.05).</p><p><b>CONCLUSION</b>Arg/Gln carriers were associated lower HDL-C levels in Han Chinese.</p>
