Objective To investigate the value of platelet, serum sodium and serum creatinine levels in the prognosis of patients with liver failure. Methods The clinical data of 155 patients with liver failure were retrospectively analyzed, and the patients were divided into improvement survival group (87 cases) and deterioration died group (68 cases) according to the prognosis. The hospitalization time of every patient was divided into 4 roughly equal time period, and observed at 5 points of time:T1-T5. The levels and abnormal rates of platelet, serum sodium and serum creatinine were compared. Results The T3 - T5 serum creatinine levels in deterioration died group were significantly higher than those in improvement survival group: (102.14 ± 75.67) μmol/L vs. (78.21 ± 26.68) μmol/L, (116.45 ± 110.64)μmol/L vs. (78.77 ± 29.25) μmol/L, (161.43 ± 153.23) μmol/L vs. (76.40 ± 27.26) μmol/L, and the T1 - T5 serum sodium and platelet levels were significantly lower than those in improvement survival group:(135.05 ± 6.24) mmol/L vs. (137.52 ± 5.26) mmol/L, (137.01 ± 4.99) mmol/L vs. (139.00 ± 3.89) mmol/L, (134.80 ± 16.74) mmol/L vs. (139.15 ± 3.77) mmol/L, (134.40 ± 11.69) mmol/L vs. (138.30 ± 8.75) mmol/L, (133.30 ± 8.93) mmol/L vs. (139.01 ± 9.10) mmol/L, and (122.46 ± 72.59) × 109/L vs. (149.70 ± 71.70) ×109/L, (110.18 ± 65.10) × 109/L vs. (152.09 ± 82.79) ×109/L, (107.32 ± 70.49) ×109/L vs. (169.32 ± 100.65) ×109/L, (97.06 ± 58.15) ×109/L vs. (183.57 ± 112.68) ×109/L, (94.66 ± 57.00) × 109/L vs. (191.36 ± 118.64) ×109/L, and there were statistical differences (P<0.05). The abnormal rates of T3-T5 serum creatinine, T2 - T5 serum sodium and T1 - T5 platelet in deterioration died group were significantly higher than those in improvement survival group, the serum creatinine: 22.06%(15/68) vs. 6.90% (6/87), 27.49% (19/68) vs. 8.05% (7/87) and 42.65% (29/68) vs. 10.34% (9/87), the serum sodium: 32.35% (22/68) vs. 13.79% (12/87), 39.71% (27/68) vs. 14.94% (13/87), 48.53% (33/68) vs. 12.64%(11/87) and 60.29%(41/68) vs. 11.49%(10/87), the platelet:45.59%(31/68) vs. 21.84%(19/87), 55.88% (38/68) vs. 24.14% (21/87), 54.41% (37/68) vs. 25.29% (22/87), 55.88% (38/68) vs. 21.84%(19/87) and 61.76% (42/68) vs. 20.69% (18/87), and there were statistical differences (P<0.05). Abnormal rate of platelet was highest in each time point. Conclusions In the course of pathological changes in deterioration and dead patients, the platelet is the first and most easily affected compare with serum sodium and serum creatinine; the platelet may be a sensitive marker for predicting clinical outcome in patients with liver failure.

Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.

Objective:To explore the correlation among childhood trauma, obsessive-compulsive symptoms, and implicit and explicit memory in patients with obsessive-compulsive disorder(OCD).Methods:Fifty-two OCD patients were enrolled, and the childhood trauma was investigated by using the childhood trauma questionnaire short-form(CTQ-SF). The degree of obsessive-compulsive symptoms was assessed by using the Yale-Brown obsessive symptoms scale (Y-BOCS). In addition, the abilities of implicit memory and explicit memory were tested by vocabulary perception speed tasks and vocabulary recognition tasks.According to the scores of CTQ-SF, the patients were divided into abuse group( n=26) and neglect group( n=26). SPSS 22.0 software was used for t-test and Pearson correlation analysis. Results:Results of obsessive-compulsive symptoms, implicit memory, and explicit memory showed no differences between the abuse group and the neglect group( t=-1.959-1.839, P>0.05). The scores of obsessions symptoms(12.52±4.61) were positively correlated with the total scores of CTQ-SF (40.10±10.20)( r=0.331, P<0.05). On the subscale, the scores of obsessions were positively correlated with the scores of physical abuse(7.89±3.02), sexual abuse(6.47±2.28)( r=0.373, P<0.01, r=0.356, P<0.05). There was a negative correlation between the scores of physical abuse and the accuracy of explicit memory(68.75±13.33)( r=-0.281, P<0.05). The scores of physical neglect(8.98±2.67) was positively correlated with implicit memory response time(4 285.94±2 067.42)( r=0.314, P<0.05). Conclusion:Obsessions in patients with OCD are related to traumatic childhood experiences, especially physical abuse and sexual abuse.Physical trauma may influence the level of implicit and explicit memory in patients with OCD.

Objective:To explore the difference of brain structure between patients with early-onset depression with and without suicidal ideation and its relationship with the severity of depression.Methods:Totally 37 patients with early-onset depressive disorder with suicidal ideation and 23 patients with early-onset depressive disorder without suicidal ideation were examined by psychological assessment and magnetic resonance imaging(MRI)from 2019 to 2020.Voxel-based morphometry (VBM) technology was used to compare the differences in brain structure between the two groups of subjects, and further analyze the relationship between the gray matter volume of the different brain areas and the severity of depression. The demographic and clinical data were analyzed by SPSS 24.0 statistical software package. The comparison between the two groups was performed by double sample t-test and chi square test. SPM8 software was used for VBM statistical analysis, and double sample t test was used for image analysis and comparison between the two groups. Pearson correlation analysis was performed between the mean gray matter volume of the two groups and the scores of HAMD-17 and Beck scale for suicide ideation(BSI). Results:Compared with the group without suicide ideation, the volume of gray matter in the right middle frontal gyrus(MNI: x, y, z=28.5, 33.0, 43.5, FWE correction for mass level, P<0.05)and left angular gyrus of the suicide idea group increased(MNI: x, y, z=-37.5, -73.5, 48.0, FWE correction for mass level, P<0.05). There was no significant correlation between the gray matter volume of the right middle frontal gyrus and the HAMD-17 scale, BSI scale in patients with early-onset depression ( r=0.073, r=-0.153, both P>0.05). Conclusion:There are structural differences in the right middle frontal gyrus and left angular gyrus between patients with early-onset depression with suicidal ideation and patients with early-onset depression without suicidal ideation, and there was no significant correlation between gray matter volume and depression severity.

AIM: In order to investigate the change of CD36 expression in atherosclerosis. METHODS: Chinese minipigs were fed a normal control diet (CD) or a high fat/high cholesterol diet (HFHC) for 12 months after common carotid artery injury induced by balloon denudation. Plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) were determined by commercially enzymatic methods. CD36 mRNA and protein levels were determined by reverse transcriptase-polymerase chain reaction (RT-PCR), Western blotting and immunohistochemistry, respectively. RESULTS: After HFHC for 12 months, plasma total cholesterol, HDL cholesterol and triglyceride in HFHC minipigs were increased compared with the control. CD36 expression and aorta PPAR? in HFHC minipigs were upregulated. CONCLUSION: HFHC may induce hyper cholesterolemia, hypertriglyceridemia and upregulation of CD36 and aortic PPAR? expression.

Objective To explore the characteristics of emotional memory in adolescent with anxiety disorders.Methods Totally 40 adolescent patients with anxiety disorders who met the DSM-5 diagnostic criteria were selected as the anxiety disorder group,40 normal adolescents matched with anxiety disorder group in terms of gender,age and education level served as the control group.All subjects of the two groups were implemented by emotional memory test task.Results (1) In emotional memory test,the negative picture score of adolescent anxiety disorder group(2.10±0.75)was significantly lower than that of control group (2.76±0.92) (t=-3.29,P＜0.05).There were no significant difference in positive and neutral picture scores between the two groups(P＞0.05).(2)Compared with control group,the positive picture,neutral picture and total recognition accuracy of adolescent anxiety disorder group both were significantly decreased ((0.24±0.09) vs (0.33±0.08),(0.22±0.10) vs (0.32±0.14),(0.25±0.08) vs (0.33±0.09)) (t=-4.28,-4.28,-3.85,all P＜0.05).There was no significant difference in negative picture recognition accuracy between the two groups (P＞0.05).In adolescent anxiety disorder group,there were significant differences in the correct recognition rates of negative pictures,positive pictures and neutral pictures in anxiety disorder group (F=3.39,P＜0.05),while there was no significant difference in the control group (F=0.04,P＞0.05).(3) The positive picture recognition accuracy and total recognition accuracy in adolescent anxiety disorder group were negatively correlated with Hamilton Anxiety Scale (HAMA) (F=0.04,P＜ 0.05).Conclusion Adolescent anxiety disorders exist in emotional memory defects,and its positive emotional memory deficit is negatively correlated with the severity of anxiety.

Objective To obtain methamphetamine concentration profiles in saliva and urine samples of drug addicts and to screen the colloidal gold strip. Methods Methamphetamine concentration in saliva and urine samples of drug addicts was determined by liquid chromatography tandem mass spectrometry. The initial screening was obtained by colloidal gold strip test. The results were compared and analyzed. Results using the method of protein and fluid MRM scan method to detect direct precipitation, saliva is linear in the range of 1~100ng/mL, the linear correlation coefficient is 0.9987, the detection limit is 0.1ng/mL, the limit of quantification was 1ng/mL, the urine is linear in the range of 1~100ng/mL, the linear correlation coefficient is 0.9943, the detection limit is 0.5ng/mL, the limit of quantification was 1ng/mL. Saliva and urine samples diluted, the concentration in the linear range. Saliva and urine samples of four types of methamphetamine colloidal gold reagent strip were screened directly, and the results were judged visually. Conclusion the detection rate of colloidal gold strip is about 79%, the detection rate of saliva is about 81%, and the detection rate can be increased to more than 93% by using two reagent strips. Combined with the initial screening results and the instrument confirmation concentration, it can be found that the gray zone setting and sensitivity setting have certain influence on the detection rate, and it is suggested to improve the sensitivity to meet the needs of screening.

Objective:To investigate the difference of the attention bias of the resilience level of professional technicians in hospital to negative information.Methods:A total of 383 professional technicians of logistics admin-istrative posts in a third-level military hospital were selected and divided into high and low groups according to their scores on the resilience scale(the top 27％of the participants were in the high resilience group,and the bottom 27％were in the low resilience group).There were 22 participants in each of the high and low resilience groups that met the requirements.The attention bias test was conducted on the professional technicians in the high and low resil-ience groups using the Dot-probe Paradigm.A mixed experimental design of 2(group:low resilience group,high re-silience group)x 2(stimulus clues:negative stimulus,neutral stimulus)was adopted.The dependent variables were correct rate and reaction time.Results:The interaction between the response group and the stimulus cue was statisti-cally significant(P＜0.05),the response time of negative stimulus in low resilience group was lower than that of neutral stimulus.The main effect of the cue condition was statistically significant in both groups(P＜0.05),the correct rate of negative stimulus was lower than that of neutral stimulus.Conclusion:This study shows that the pro-fessional technicians in the high resilience group do not have obvious attention bias to negative information,while the professional technicians in the low resilience group have obvious attention bias to negative emotional informa-tion.

Objective To investigate the impairment of intertemporal choices in adolescents with positive and negative schizophrenic symptoms.Methods 30 adolescent schizophrenia patients with positive symptoms (positive symptoms group),30 adolescent schizophrenia patients with negative symptoms (negative symptoms group)and 30 healthy controls were selected.All the subjects were investigated with intertemporalchoice Test.Results (1) Under now conditions ((37.22±30.92)％,(19.67±16.35)％,P＜0.05)),notnow conditions ((35.74±31.69)％,(19.33± 18.07)％,P＜0.05)) and overall condition ((36.48±30.44) ％,(19.50± 13.82)％,P＜0.05)),the ratio of later-large (LL) choice in negative symptoms group were significantly higher than those in the healthy controls.Under now conditions ((37.22±30.92) ％,(20.37±22.33) ％,P＜0.05)),not-now conditions ((35.74± 31.69) ％,(22.04±22.05) ％,P＜ 0.05)) and overall condition ((36.48±30.44) ％,(21.20±21.57) ％,P＜0.05)),the ratio of LL choice in negative symptoms group were significantly higher than those in positive symptoms group.There were no differences in the ratio of LL choice between positive symptoms group and healthy controls (P＞ 0.05).(2)Pearson correlation analysis showed that the Vocabulary Fluency Test of negative symptoms group was positively correlated with LL selection ratio under now conditions (r=0.411,P=0.024).Conclusion The ability of intertemporal choices in adolescents schizophrenia patients with negative symptoms is impaired remarkably,while this kind of ability is impaired unremarkable in adolescence with negative symptoms.The ability of intertemporal choices in adolescents schizophrenic patients with negative symptoms is correlated with cognitive executive function.
