Objective To investigate the expression of neuron-specific enolase(NSE) and bone morphogenic protein 4(BMP4) in different hippocampal areas of pentylenetetrazol(PTZ) kindled epilepsy rats and explore their relationship with the pathogenesis of epilepsy and brain injury.Methods Fifty male SD rats were divided into experimental group(n=40) and control group(n=10).The rats in experimental group were kindled into epilepsy by chemical method,and according to the kindling process,subdivided into four groups(grade Ⅰ,Ⅲ,Ⅳ,Ⅴ).Immunohistochemistry,in situ hybridization labeled with Dig-oligonucleotide probe and the image analyzing system were used to observe the expressions of NSE and BMP4 in rat hippocampus.Results In PTZ kindled epilepsy rats,the number of cells positive for NSE and BMP4 was increased in many regions of hippocampal formation.Compared with control group,the expressions of NSE and BMP4 in CA3 and DG was elevated obviously in the grade Ⅲ group and grade Ⅳ group(P

Objective: To analyze the clinical features and risk factors of ulcerative colitis (UC)complicated with Epstein-Barr(EB)-viremia and the effect of antiviral therapy on the remission of the symptoms. Methods: From April 2014 to January 2018, data of 239 UC patients hospitalized at the Department of Gastroenterology of Second Hospital of Hebei Medical University were collected. The patients were divided into EB-viremia group (trial group, n=43) and non-EB-viremia group (control group, n=196) according to EB virus-DNA detection. The general condition, clinical characteristics and therapeutic efficacy of the two groups were compared. The risk factors and the effect of antiviral therapy on the remission of symptoms of UC complicated with EB-viremia were analyzed. Chi-square test and logistic analysis were used for statistical analysis. Results: There were no significant differences in gender, age, clinical type, lesion range, the proportion of patients treated with 5-aminosalicylic acid or corticosteroids, the percentage of patients with diarrhea and bloody stool, the proportion of patients with spontaneous bleeding, platy ulcer and longitudinal ulcer under colonoscopy, the course of disease or Mayo score between the trial group and control group (all P>0.05). The proportions of patients with smoking history and severe disease, treatment with azathioprine and 6-mertocapurine (6-MP), treatrnent with infliximab, symptoms of fever or abdominal pain and deep and large ulcer under colonoscopy in the trial group were all higher than those in the control group, and the differences were all statistically significant (χ²=5.304, 6.608, 6.718, 6.939, 8.783, 4.493 and 5.425, all P<0.05). The results of multivariate logistic regression analysis showed that smoking history and treatment with azathioprine and 6-MP were risk factors of UC complicated with EB-viremia (OR=2.801 and 9.343, 95%CI 1.170 to 6.703 and 1.749 to 49.922, P=0.021 and 0.009). The improvement rates of the trial group and control group were 79.1%(34/43) and 95.4%(187/196), respectively. There was a significant difference in the improvement rate between the two groups (χ²=10.551, P=0.001). In the trial group, 12 patients (27.9%) received ganciclovir treatment, fonr patients (9.3%) had foscarnet sodium treatment, 21 patients (48.8%) were treated with the combination of these two medications and six cases (14.0%) did not received any antiviral treatment. After three weeks, the improvement cases of the above regimens were 8, 4, 16 and 6, respectively. There were no statistically significant differences in the improvement rate of patients with and without antiviral treatment, further more, no difference was found in the improvement rate of patients with different antiviral treatments (all P>0.05). Conclusions Smoking history and purine treatment are risk factors of UC complicated with EB-viremia.

Objective:To explore the differences of attention bias performance between patients with heroin dependence in methadone maintenance treatment(MMT) and healthy controls.Methods:A total of 38 heroin dependent patients in the Fourth People's Hospital of Huainan from January 2018 to September 2018 were selected as MMTgroup, and 32 gender-and age-matched healthy controls were selected as healthy control(HC) group.The attention bias was evaluated by Emotional Stroop Task, and the difference between the two groups was compared.Results:The error number of the herion-related words in Emotional Stroop Task of MMT group was lower than that of HC group[0.75(2, 5) vs.1(0, 2)], the difference was statistically significant( Z=-2.184, P=0.029). The number of errors in point and neutral words and reaction time of point, neutral word and clue word had no statistically significant differences between MMT group and HC group[1(0, 4) vs.1(0, 2); 3(2, 5) vs.2(2, 3); (1 055.14±303.50)ms vs.(985.40±173.71)ms, (1 126.89±347.82)ms vs.(1 022.76± 173.62)ms; (1 188.53±371.80)ms vs.(1 113.23±225.11)ms]( Z=-1.331, P=0.183; Z=-1.723, P=0.085; t=1.150, P=0.254; t=1.539, P=0.129; t=1.001, P=0.320). There were no statistically significant differences in attention bias influenced by the dosage and duration of methadone between MMT group and HC group(all P>0.05). Conclusion:These results demonstrate that heroin dependence patients in MMT have attentional bias in heroin-related words.Methadone has no effect on attention bias in patients with heroin dependence during maintenance treatment intervention.

Objective: To explore the effects of macrophages with high expression of TL1A on the activation and proliferation of HSCs in vitro. Methods: The Bone marrow-derived macrophages (BMMs) and peritoneal macrophages (PMs) from wild type (WT) and myeloid-overexpressed TL1A transgenic mice were isolated, differentiated and activated. HSCs were harvested from activated macrophages culture supernatant (CM). HSCs were detected by immunofluorescence and real-time Q-PCR. And the proliferation was detected by CCK-8 and BrdU assay kit. The levels of IL-1β and PDGF-BB in macrophage culture supernatants were determined by enzyme-linked immunosorbent assay (ELISA). Results: BMMs-derived CM-intervention HSCs were used to detect the expression of α-smooth muscle actin (α-SMA) on the 2nd, 4th and 6th day respectively by immunofluorescence method. There was no significant difference between the two groups on the 2 nd and the 6th day, P > 0.05; On day 4, the CM/Tg group was significantly higher than that of CM/WT group, P < 0.01; the results of CMs derived from PMs were consistent with the above trend. The expression of α-SMA mRNA on the 2nd, 4th and 6th day was detected by real-time Q-PCR method using BM-derived CMs. No significant difference was found between the groups on the 2nd day (P > 0.05).α-SMA mRNA increased further on the 4th and 6th day, and the level of CM/Tg in CM/Tg group was significantly higher than that in CM/WT group (P < 0.05). The detection results of CMs derived from PMs were consistent with the above trend. The results of CCK-8 assay and BrdU assay showed that the proliferation rate of HSCs in CM Tg group was significantly higher than that in CM/WT group (P < 0.01). The CMs derived from PMs were used to interfere with HSCs. And the results were consistent with the above trend. For BMMs, the levels of IL-1β and PDGF-BB in the lipopolysaccharide (LPS) + IFNγ/Tg culture supernatant were significantly higher than those in the LPS+IFNγ/WT group (P < 0.01). For the culture supernatants of PMs Liquid test results consistent with the above trend. Conclusion Macrophages with high expression of TL1A could enhance the activation and proliferation of HSCs by increasing the secretion of IL-1β and PDGF-BB.

Objective To investigate the effects of tumor necrosis factor-related ligand-1A(TL1A)on activation of T helper 9(Th9)cells of colonic tissues in chronic experimental colitis mice.Methods The chronic experimental colitis mice model was established with drinking dextran sulfate sodium salt(DSS).A total of 32 lymphocytes TL1A highly expressed mice and wild type(WT)mice were divided into WT control group, transgene control group,WT modeling group and transgene modeling group.The mice of control groups were administrated with distilled water. The mice of modeling groups received 3% DSS in drinking water discontinuously.The mice were sacrificed on 29 days after modeling.Body mass was measured,length of colon was recorded,scores of gross colon and the disease activity index(DAI)were calculated.The colonic morphological changes were observed by hematoxylin-eosin(H-E)staining.The lamina propria mononuclear cells(LPMC)were isolated and the number of Th9 cells was tested by flow cytometry.The levels of interleukin-9(IL-9)in serum and LPMC were detected by enzyme-linked immunosorbent assay(ELISA).The expressions of IL-9 protein and mRNA of the colonic tissues were measured by Western blotting and real-time polymerase chain reaction(PCR),respectively.T test and single factor analysis of variance were performed for statistical analysis.Results The percentage of body mass loss of WT modeling group was lower than that of transgene modeling group(16.2% ± 1.0% vs 18.9% ± 1.2%),and the difference was statistically significant(t=4.90, P<0.05).The scores of gross colon,DAI and pathology of transgene modeling group were all higher than those of WT modeling group(2.80 ± 0.64 vs 1.60 ± 0.31,2.55 ± 0.20 vs 1.58 ± 0.17,and 11.85 ± 0.86 vs 9.50 ± 0.79),and the differences were statistically significant(t=4.77,10.45 and 5.69,all P<0.05).The number of LPMC in transgene modeling group was higher than that of WT modeling group(3.70×106± 0.28×106vs 2.65×106± 0.32 × 106)and the difference was statistically significant(t= 6.98,P< 0.05).The percentage of Th9 in total CD4+T cells of LPMC in colonic tissues of transgene modeling group was higher than that of WT modeling group(0.54% ± 0.04% vs 0.23% ± 0.03%),and the difference was statistically significant(t= 17.54,P< 0.05).The serum IL-9 level of transgene modeling group was higher than that of WT modeling group((170.23 ± 5.69)pg/mL vs(150.62 ± 6.45)pg/mL),and the difference was statistically significant(t= 6.50,P< 0.05).The level of IL-9 secreted by LMPC of transgene modeling group was higher than that of WT modeling group((265.21 ± 8.76)pg/mL vs (237.58 ± 10.24)pg/mL),and the difference was statistically significant(t= 5.80,P< 0.05).The expressions of IL-9 protein and mRNA of transgene modeling group were higher than those of WT modeling group(1.31 ± 0.09 vs 1.18 ± 0.03,and 8.26 ± 1.13 vs 2.25 ± 0.29,respectively),and the differences were statistically significant(t=3.88 and 14.57,both P< 0.05).Conclusion TL1A high expression in lymphocytes can promote Th9 cells differentiation and IL-9 secretion which involved in the genesis of chronic experimental colitis.

Objective:To explore the risk factors, clinical features, endoscopic characteristics and the efficacy of antiviral therapy in ulcerative colitis (UC) patients complicated with cytomegaloviremia (CMV) and Epstein-Barr (EB) viremia.Methods:From April 1, 2014 to January 31, 2019, at The Second Hospital of Hebei Medical University, a total of 320 UC patients hospitalized at the Department of Gastroenterology were enrolled. According to the pathogens, the patients were divided into four groups: complicated with CMV and EB viremia group ( n=35), only complicated with CMV viremia group ( n=33), only complicated with EB viremia group ( n=52) and without CMV and EB viremia group ( n=200). Clinical features and the efficacy of antiviral therapy of the patients were retrospectively analyzed. Multivariate logistic regression was used to analyze the risk factors of UC complicated with CMV and EB viremia. Kruskal-Wallis H test, Chi-square test and Fisher exact test were used for statistical analysis. Results:The proportion of patients of age>60 years old (42.86%, 15/35), the rate of glucocorticoid use (51.43%, 18/35) within three months before onset and the inefficacy rate of glucocorticoid treatment (22.86%, 8/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (14.00%, 28/200; 24.50%, 49/200; 1.00%, 2/200), and the differences were statistically significant ( χ2=17.062, 10.598 and 29.769; all P<0.01). However, there were no statistically significant differences between UC complicated with CMV and EB viremia group and UC without CMV and EB viremia group in gender, and treatment of 5-aminosalicylic acid (5-ASA), azathioprine and infliximab within three months before onset (all P>0.05). The proportion of patients with fever (54.29%, 19/35), abdominal pain (91.43%, 32/35), hematochezia (94.29%, 33/35), weight loss (28.57%, 10/35), severe disease activity (94.29%, 33/35), total colon involvement (91.43%, 32/35), serum albumin less than 30 g/L (71.43%, 25/35) and hemoglobin less than 100 g/L (48.57%, 17/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (13.50%, 27/200; 43.00%, 86/200; 44.00%, 88/200; 13.50%, 27/200; 38.00%, 76/200; 65.00%, 130/200; 18.00%, 36/200 and 18.50%, 37/200), and the differences were statistically significant ( χ2=31.475, 27.945, 32.930, 5.100 and 40.194, Fisher exact test, χ2=44.242 and 15.220, all P<0.01). However, there were no statistically significantl differences in clinical classification and disease course (all P>0.05). The incidence rates of deep ulcer (45.71%, 16/35), irregular ulcer (42.86%, 15/35) and longitudinal ulcer (8.53%, 3/35) under endoscopy of UC complicated with CMV and EB viremia group were significantly higher than those of UC without CMV and EB viremia group (1.50%, 3/200; 3.50%, 7/200 and 1.00%, 2/200), and the differences were statistically significant ( χ2=72.521 and 49.837, Fisher exact test, all P<0.01). The incidence rates of deep ulcer and irregular ulcer under endoscopy of UC complicated with CMV and EB viremia group were higher than those of UC only complicated with EB viremia group (15.38%, 8/52 and 11.54%, 6/52), and the differences were statistically significant ( χ2=9.663 and 11.206, P=0.002 and 0.001). The results of Multivariate Logistic regression analysis showed that severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy were risk factors of UC patients complicated with CMV and EB viremia (odds ratio=48.519, 44.352, 53.432 and 39.989, 95% confidence interval 9.057 to 587.669, 4.499 to 437.245, 3.302 to 864.670 and 3.418 to 467.910, all P<0.05). The improvement rate of antiviral therapy in UC complicated with CMV and EB viremia group (73.53%, 25/34) was significantly lower than those of UC only complicated with CMV group (96.88%, 31/32) and UC only complicated EB viremia group (95.65%, 44/46), and the differences were statistically significant ( χ2=6.989 and 6.310, P=0.008 and 0.012). Conclusions:UC patients with severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy are more likely to develop CMV and EB viremia. The more severe the disease, the worse the treatment response, so it is necessary to strengthen the screening to CMV and EB virus infection in UC patients.

Objective: To explore the correlation between different nutritional status and depressive symptoms among adolescents, so as to provide a theoretical basis for targeted improvement of nutritional status and depressive symptoms in adolescents. Methods: A total of 8 102 adolescents aged 12-17 years in Shanghai, Urumqi, Changsha and Kunming were selected by random cluster sampling. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale(CES-D). Height and weight were measured. Kruskal Wallis H test, Chi square test and ordinal Logistic regression were used to analyze the relationship between nutritional status and depressive symptoms in adolescents. Results: The overall detection rate of depressive symptoms in adolescents was 25.6%, with girls (30.1%) higher than that of boys (21.1%) ( χ 2=87.60, P <0.01). There were statistically significant differences in the scores of depressive symptoms among girls with different nutritional status ( Z =8.34, P <0.05). The detectable rate of depressive symptoms increased with BMI among girls( χ 2 trend =6.04, P <0.05). After controlling for confounding factors, ordinal Logistic regression showed that the obese girls had higher risks in depressive symptoms detection compared with normal weight girls ( OR=1.45, 95%CI=1.10-1.91, P <0.05). Conclusion The nutritional status of girls is better than boys, but the prevalence of depressive symptoms is higher than boys. The risk of depressive symptoms in girls increases with BMI.

Objective: To explore the correlation between non suicidal self injury(NSSI) behaviors and depressive symptoms in adolescents and to provide a theoretical basis for improvement of adolescent physical and mental health. Methods: A total of 8 102 adolescents aged 12-17 years were selected by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming, using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Adolescent Non Suicidal Self Injurious Behavior Assessment Questionnaire. Depressive symptoms and the occurrence of NSSI behaviors were assessed. The relationship between NSSI behaviors and depressive symptoms was analyzed using Chi square test, one way analysis and Logistic regression analysis. Results: The overall detection rate of NSSI in adolescents, 24.6%, with a significantly lower detection rate in boys (23.1%) than in girls (26.2%) ( χ 2=10.97, P <0.05), and 24.7%, 24.6% in the middle school and high school segments, respectively, but the difference was not statistically significant ( χ 2=0.01, P >0.05). The overall detection rate of adolescent depressive symptoms was 49.7 % in the group with NSSI and 17.7% in the group without NSSI, with statistically significant differences ( χ 2=808.80, P < 0.01 ). The detection rates of adolescent depressive symptoms in the group with NSSI (male:44.0%, female:54.7%, middle school:49.6%, high school:49.8%) and the group without NSSI (male:14.2%, female:21.4%, middle school:14.3%, high school: 21.0 %) were statistically significant by sex and age groups ( χ 2=385.58, 412.44, 520.60, 313.78, P ＜0.01). Logistic regression models, after adjusting for gender and age, the risk for depressive symptoms was 2.65 times (95% CI =2.27-3.09) and 7.28 times (95% CI = 6.34- 8.37) more frequently in adolescents with episodic self injurious behavior and frequent self injurious behavior, respectively, compared to those without self injurious behavior. The association between NSSI status and depressive symptoms did not show sex differences ( P >0.05). Conclusion Adolescent NSSI behavior is positively associated with depressive symptoms, the attention should be paid to adolescent physical and mental health to reduce the occurrence of NSSI.
