Objective: To examine the correlation of symptomatic feature and exploratory eye movements in schizophrenia. Methods: The eye movements of 60 patients with schizophrenia and 30 healthy control subjects were measured by the eye-mark recorder (model IV, Japan) and symptom profiles of patients were assessed using the Positive and Negative Syndrome Scale (PANSS) . Pearson correlation analysis was performed to examine the relationship between five-factor scores of PANSS, positive symptoms, negative symptoms and exploratory eye movements respectively. Results: The differences of all indices of eye movements between schizophrenic groups and normal control group had statistical significance ( P

Objective To investigate the serum levels of uric acid (UA) in bipolar disorder patients and their clini?cal significance. Methods Serum levels of UA was measured in 126 bipolar disorder patients including 77 mania pa?tients and 49 depression patients, 69 first-episode schizophrenic patients and 126 healthy controls (control group). Bipo?lar disorder patients was assessed by using the Young Mania Rating Scale (YMRS) and the Hamilton Depression Scale (HAMD). Results The serum UA levels were significantly higher in bipolar group [(349.34 ± 107.21) μmol/L] than in schizophrenic group [(319.71±84.48)μmol/L] and in control group [(280.94±71.90)μmol/L] (P<0.01). There were signifi?cant differences in serum UA levels between manic episode and depressive episode [(366.45 ± 104.01) μmol/L vs. (322.45±107.69)μmol/L]. The serum UA levels were higher in both manic episode and depressive episode groups than in control group (P<0.01). The serum UA levels was not significantly different between patients with and without medication (P>0.05). Correlation analysis indicated that the correlation of serum UA levels with YMRS scores and HAMD scores was not significant in bipolar disorder patients (P>0.05). Conclusions Patients with bipolar disorder has elevated serum uric acid levels which may be a biomarkers of bipolar disorder.

Objective To explore the association between serum levels of homocysteine (Hcy) and relation factors in the patients with manic episodes of bipolar Ⅰ disorder(BD).Methods The case-control study was used for this study.A total of 73 inpatients with manic episodes of BD(patient group) and 39 healthy individuals (control group) were enrolled.Diagnosis was made according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM-Ⅳ) criteria.Serum levels of Hcy was measured by enzymatic cycling assay.Young Mania Rating Scale(YMRS) were used to assess the severity of clinical symptoms of patients.Results There was a statistical difference in serum Hcy levels between patient group ((16.89± 14.67)μmol/L) and control group ((10.61±6.46) μmol/L) (P＜0.01),and serum Hcy levels was higher in men((20.42± 16.52) μmol/L) than that in women((10.87±8.02) μmol/L) in patients group(P＜0.05).The prevalence rate of high Hcy was 35.6％ in the patient group and 13.5％ in the control group(P＜0.05).Correlation analysis showed body mass index(BMI) had positive correlation with serum levels of Hcy (r=0.317,P＜0.05).Stepwise multiple regression analysis showed male,BMI were associated with serum levels of Hcy among the patients (all P＜ 0.05).Conclusion Serum Hcy levels in the patients with manic episodes of bipolar Ⅰ disorder increase,and it is associated with gender and BMI.

Objective To explore the efficacy of group cognitive behavioral therapy for improving depressive symptoms and social functional in patients with major depressive disorder.Methods A total of 160 patients with major depressive disorder were randomly divided into intervention group (n=80) and control group (n=80).Intervention group was treated with conventional antidepressants combined with group cognitive behavioral therapy.Control group was treated with one conventional antidepressants.All participants were assessed with Hamilton Depression Scale (HAMD)and Scale of Social function of Psychosis Inpatients (SSFPI) before and 8 weeks after the treatment.Results After 8 weeks treatment,the scores of HAMD (14.76±9.48) was significantly reduced and the scores of SSFPI(30.09±4.34) were significantly increased in intervention group compared with the baseline ((37.91± 10.58),(12.40±2.56),all P＜0.01).The scores of HAMD were significantly lower and the scores of SSFPI were significantly higher in intervention group than that in control group((20.71±7.85),(22.63±3.63),all P＜0.01).Conclusion Group cognitive behavioral therapy is effective for major depressive disorder patients by reducing depressive symptom and improving social function.

Purpose To explore the CT manifestations and pathological features of pneumonia-type lung cancer, and to improve the diagnosis capability of pneumonia-type lung cancer. Materials and Methods CT and pathologic features of 33 cases of biopsy or surgical pathology confirmed pneumonia-type lung cancer patients were retrospectively analyzed and classified according to the new pulmonary adenocarcinoma classification. Results Among the 33 pneumonia-type lung cancer subjects, CT showed multiple distributions within both lungs in 22 cases, lateral lobe distribution in 9 cases, segmental distribution in 2 cases. Lung consolidation was found in all lesions, among them 21 cases appeared mainly as lower lobe consolidation, 32 cases as inflatable bronchial symptoms within the consolidation, including inflatable bronchoconstriction in 24 cases;consolidation with multiple pulmonary nodules found in 23 cases;ground glass shadowing around or distal to the consolidation found in 26 cases;combined with cysts or honeycomb lung symptom in 13 cases. Inhomogeneous mild enhancement of lung consolidation after enhancement found in 18 cases and inhomogeneous moderate enhancement in 15 cases;blood vessel branch shadow within the consolidation was visible in 21 cases. Pathology results revealed 26 cases of invasive mucinous adenocarcinoma, and 7 cases of invasive mucinous adenocarcinoma partial mixed with papillary or alveolar adenocarcinoma. Conclusion CT features of pneumonia-type lung cancer are single or multiple opacities, within which inflatable bronchial symptoms can be observed, with multiple nodules and ground glass shadowing, cysts or honeycomb symptom can also be found concomitant, the lesions expand, increase and spread to both lungs, taking its dynamic change features into consideration will also help to improve the diagnostic accuracy.

Objective: To investigate the social support of medical students during the outbreak of COVID-19 and its mediating effect on the correlation between epidemic exposure and depression with anxiety. Methods: A total of 5 593 medical students were enrolled, and Social Support Rating Scale(SSRS), Patient Health Questionnaire-9 and 7-tiem Generalize Anxiety Disorder Scale were used to measure. Results: The social support score of SSRS of male students was lower than that of female students (t=-4.36, P<0.05) and juniors and seniors scored lower than other grades(F=4.84, P<0.05). Epidemic exposure proportion was positively correlated with both depressive proportionand anxiety proportion(r=0.05, 0.06, P<0.01), while epidemic exposure and depressive proportion and anxiety proportion were negatively correlated with social support score(r=-0.05, -0.25, -0.19, P<0.01). After controlling for gender and grade, the mediating effect of social support in the correlation between epidemic exposure and depression accounted for 26.6% of the total effect, and the mediating effect of subjective support and supportive utilization was 32.3% and 25.7% respectively. After controlling for gender and grade, the mediating effect of social support in the correlation between epidemic exposure and depression accounted for 20.0% of the total effect, and the mediating effect of subjective support and supportive utilization was 15.9% and 12.2% respectively. Conclusion Social support has partially mediating effect in the correlation between epidemic exposure with depression and anxiety.

Objective: To explore the relationship among cognitive flexibility, depression and eating attitude of adolescents and the influencing factors of eating attitude. Methods: A total of 1 231 subjects were assessed using general information questionnaire, Kutcher Adolescent Depression Scale 11 item(KADS-11), Cognitive Flexibility Inventory(CFI), Eating Attitude Test 26(EAT-26). Data were analyzed by independent sample t-test, univariate linear regression, spearman correlation analysis and Logistic regression. Results: There were significant differences in EAT 26 among adolescents between genders and between those with or without depression(P<0.01). Statistically significant differences were observed in CFI, flexible control and KADS 11 among adolescents with or without eating disorders(P<0.01). The scores of EAT 26 was negatively correlated with CFI (r=-0.19, P<0.01) and flexible control(r=-0.23, P<0.01). And there was a significant positive correlation between EAT 26 and KADS 11(r=0.23, P<0.01). Female(OR=2.40, 95%CI=1.87-3.23), depression (OR=1.76, 95%CI=1.35-2.29) and poor flexible control (OR=1.94, 95%CI=1.48-2.54) were risk factors for eating disorders. Conclusion Female, individuals with depressive symptoms or with poor flexible control ability are more likely to have eating disorders which need more attention.

Objective:To explore the mediating role of self-hating in the influence of adverse childhood experiences on adolescents' negative emotions.Methods:A questionnaire method was used to collect demographic variables, and 7 012 valid questionnaires were obtained from adolescents by applying the revised adverse childhood experiences questionnaire, patient health questionnaire-4, and self-hate scale from May 1 to May 30, 2022, in five high schools(90 classes) and five junior high schools(60 classes) in Rizhao city, Shandong province, China. Data entry and analysis were performed by SPSS 22.0 software.Mann-Whitney U test was used for the comparison between demographic variables and other variables, and the correlations between variables were expressed by Spearman correlation coefficient. AMOS 23.0 software was applied for testing the mediating and moderating effects of variables. Results:(1)There were significant positive correlations between adverse childhood experiences(0(2)) and negative emotion(3(10))( r=0.459, P<0.01), self-hating(2(4))( r=0.427, P<0.01). There were significant positive correlations between self-hating and negative emotion( r=0.566, P<0.01). (2) Self-hating played a mediating role between adverse childhood experience and adolescent negative emotion, and the mediating effect was 0.299, accounted for 61.27% of the total effect.(3) The mediating pathway of self-hated was moderated by gender, with girls' adverse childhood experiences( Bsimple=2.428, t=39.585, P<0.05) predicting self-hating more than boys( Bsimple=1.641, t=25.355, P<0.05). Conclusion:Adverse childhood experiences can predict adolescents' negative emotions, and self-disgusting can also affect adolescents' negative emotions.Gender plays a moderating role in the mediating pathway.

Objective:To explore the situation of insomnia, fatigue, depression, anxiety and cognitive impairment in adolescents with different characteristics, and the chain mediating effect of fatigue, depression and anxiety on insomnia and cognitive impairment.Methods:The general demographic data of 6 014 adolescents were collected.Insomnia severity index (ISI), the multidimensional fatigue inventory (MFI-20), patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7) and perceived deficits questionnaire-depression(PDQ-D) were used to compare the insomnia, fatigue, depression, anxiety and cognitive impairment of adolescents with different characteristics.Spearman correlation analysis was conducted by SPSS 20.0 software.The significance of mediating effect was tested by deviation corrected nonparametric percentile Bootstrap method using SPSS macro program PROCESS.Results:The detection rates of insomnia, fatigue, depression, anxiety and cognitive impairment were different in adolescents with different genders, grades and academic achievements.Cognitive impairment was significantly positively correlated with insomnia ( r=0.654, P<0.01), fatigue ( r=0.476, P<0.01), depression ( r=0.677, P<0.01), anxiety ( r=0.655, P<0.01), which was suitable for mediating effect test.Fatigue, depression and anxiety in adolescents had a chain mediating effect between insomnia and cognitive impairment.Insomnia indirectly affects cognition by affecting fatigue and depressive symptoms.The intermediary effect value was 1.253, the effect amount was 55.60%, and the total effect was 2.254.Insomnia indirectly affects cognition by affecting fatigue and anxiety symptoms.The intermediary effect value was 1.161, the effect amount was 51.50%, and the total effect was 2.254. Conclusion:Insomnia can not only directly affect their cognitive impairment, but also indirectly affect their cognitive impairment through the chain mediation of fatigue, depression and anxiety of adolescents.
