ABSTRACT
Objective:To compare the effectiveness of intravenous thrombolysis(IVT)alone versus mechanical thrombectomy(MT)in treating acute large vessel occlusive stroke(AIS-LVO).Amd to analyze the factors that are associated with the prognosis of MT.Methods:A total of 197 patients with acute ischemic stroke with large vessel occlusion(AIS-LVO)who received intravenous thrombolysis(IVT)and/or mechanical thrombectomy(MT)at the Stroke Center of the Second Hospital of Dalian Medical University from April 2016 to July 2021 were included in this retrospective analysis.Baseline data, clinical data, and 90-day Modified Rankin Scale(mRS)scores were collected for each group.The efficacy and risk of IVT alone and MT were compared using univariate and multivariate logistic regression analysis.Additionally, factors influencing the prognosis of MT were identified.Results:A total of 197 patients who met the inclusion criteria were included in this study.Out of these, 62 patients were in the IVT alone group and 135 patients were in the MT group.The results of the univariate analysis showed that the MT group had lower admission systolic blood pressure(147±23 vs.158±27 mmHg, P=0.003), higher baseline NIHSS score[15(12, 19) vs.12(8, 16), P=0.003], and there were also differences in vascular occlusion between the two groups( χ2=15.504, P=0.004).Specifically, the middle cerebral artery and basilar artery occlusion were higher in the MT group.In terms of outcome, the MT group had a higher percentage of good outcomes at 90 days[53(39%) vs.13(21%), χ2=6.381, P=0.012], and there was no significant difference in symptomatic intracranial hemorrhage(sICH)and mortality within 90 days.Among the 135 patients who underwent MT, 53 patients were classified as having a good prognosis, while 82 patients were classified as having a poor prognosis.Multivariate analysis revealed that age( OR=1.078, 95% CI: 1.025-1.133, P=0.003), neutrophil to lymphocyte ratio(NLR)( OR=1.164, 95% CI: 1.013-1.338, P=0.032), time from onset to recanalization( OR=1.004, 95% CI: 1.000-1.007, P=0.049), sICH( OR=15.585, 95% CI: 1.397-173.865, P=0.026), ASPECTS/pc-ASPECTS score( OR=0.524, 95% CI: 0.017-0.582, P=0.024), and good recanalization( OR=0.099, 95% CI: 1.718-59.046, P=0.010)were identified as independent prognostic factors.The results indicate that percutaneous transluminal angioplasty, stent implantation, and the use of tirofiban and butylphthalide did not significantly affect the prognosis of the MT group. Conclusions:The use of mechanical thrombectomy(MT)in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)is more effective than intravenous thrombolysis(IVT)alone and has a similar safety profile.However, there are certain factors that can influence the prognosis of MT treatment.Older age, higher neutrophil-to-lymphocyte ratio(NLR), longer time from symptom onset to recanalization, and the occurrence of postoperative symptomatic intracranial hemorrhage(sICH)were identified as independent predictors of poor prognosis in MT treatment.On the other hand, a higher ASPECTS/pc-ASPECTS score and successful recanalization were found to be protective factors associated with a favorable prognosis in MT treatment.
ABSTRACT
Objective:To investigate the correlation between the prognosis of late-onset depression(LOD)in the elderly and lncRNA expression levels and coping styles.Methods:Differential expression of lncRNAs in peripheral blood of LOD 92 patients was detected by a real-time quantitative PCR(qPCR)detection system, and the Hamilton Depression Scale(HAMD)and the Trait Coping Style Questionnaire(TCSQ)were used for psychological assessment.Results:Compared with the control group, the expression levels of TCONS_00019174(7.55 vs.4.36), ENST00000566208(6.48 vs.3.26), ENST00000517573(8.33 vs.5.32)and NONHSAT142707(6.78 vs.3.26)in elderly patients of the LOD group were significantly down-regulated( Z=5.09, 5.87, 4.35, 6.44, P<0.05); Compared with the low-expression subgroup, scores of anxiety/somatization[(3.83±1.40) vs.(6.39±2.35)], diurnal variation[(0.22±0.42) vs.(0.83±0.94)], retardation[(5.74±0.96) vs.(6.48±1.28)], hopelessness[(2.78±0.67) vs.(4.52±1.56)]and HAMD[(20.39±1.75) vs.(26.83±4.88)]in the high-expression subgroup were significantly lower( t=-4.50, -2.84, -2.22, -4.90, -5.96, P<0.05). The ΔCT value of TCONS_00019174 was negatively correlated with the reduction rates of anxiety/somatization, diurnal variation, retardation, sleep disturbance, hopelessness and HAMD( r=-0.40-0.66, P<0.05). The ΔCT value of ENST00000566208 was negatively correlated with the reduction rates of anxiety/somatization, sleep disturbance, hopelessness and HAMD( r=-0.47-0.62, P<0.01). The ΔCT values of ENST00000517573, NONHSAT034045 and NONHSAT142707 were negatively correlated with the reduction rates of retardation, sleep disturbance, hopelessness and HAMD( r=-0.39-0.76, P<0.05). The positive coping style was positively correlated with the reduction rates of HAMD, anxiety/somatization, retardation, sleep disturbance and hopelessness( r=0.38-0.55), while the negative coping style was negatively correlated with the reduction rates of HAMD, anxiety/somatization, sleep disturbance and hopelessness( r=-0.39-0.67, P<0.05). When TCONS_00019174, ENST00000566208, NONHSAT034045, NONHSAT142707, positive coping and negative coping were taken into the regression equation as variables for HAMD reduction, it was found that they were able to explain 32.4% of the variance for the reduction rate of the total HAMD score( t=-8.713, -3.584, -3.864, -2.257, 5.675, -2.357, P<0.05). Conclusions:TCONS_00019174, ENST00000566208, NONHSAT034045, NONHSAT142707, positive coping style and negative coping style are predictors of the prognosis of LOD in the elderly.
ABSTRACT
Objective:To establish neurodevelopmental mice model of schizophrenia(SZ) with prepulse inhibition(PPI) deficits and investigate the effectiveness of olanzapine on PPI disruption.Methods:On the 9th day of pregnancy of SPF grade C57BL/6 mice, female mice were injected with polyinosinic acid poly (I∶C) (6 mg/kg) through tail vein for immune stimulation. The stress model was constructed by chronic unpredictable mild stress 30-40 d after birth (PND30-40). The offspring mice were divided into pregnancy immune stimulation + adolescent stress group (P + S + group), pregnancy immune stimulation group (P + S- group), adolescent stress group (P-S+ group) and non stimulation group (P-S-group), with 18 mice in each group. The mice in P+ S+ group were divided into OLZ intervention group (OLZ group) and non-OLZ intervention group (non-OLZ group), with 9 mice in each group. The PPI function of mice was detected by acoustic startle reflex test after modeling and OLZ intervention. Adopt StatView Version 5.0 software for data analysis, and multi factors analysis of variance was used to test the main effect, interactive effect and simple effect of each factor.Results:The main effects of maternal Poly(I: C) immune activation and pubertal chronic unpredictable stress were significant( F(1, 330)=47.72, P<0.01), and there was a significant interaction between the two factors( F(1, 330)=14.80, P<0.01), simple effect analysis showed that average percent prepulse inhibition (PPI%) in P+ S+ group((15.42±6.13)%) was significantly decreased compared with groups of P+ S-((27.33±4.58)%), P-S+ ((31.17±3.97)%) and P-S-((47.14±12.28)%)(all P<0.01). There was significant gender difference in Prepulse inhibition(PPI)score( F(1, 396)=61.94, P<0.01), in male and female mice, average startle reactivity of Pulse under Prepulse+ Pulse influence of distinct intensities was significantly different( F(1, 198)=18.68, 18.44, P<0.01), and the maternal Poly(I∶C) immune activation had a significant main effect( F(1, 198)=32.18, 12.58, P<0.01) and interaction with pubertal chronic unpredictable stress( F(1, 198)=34.54, 11.39, P<0.01), simple effect analysis suggested that the average startle reactivity of Prepulse+ Pulse in P+ S+ group(0.47±0.12) was significantly higher than other three groups(P+ S-: 0.36±0.11, P-S+ : (0.25±0.22), P-S-: (0.31±0.19)) in male mice( P<0.01) and in P-S+ group was significantly higher than the other three groups in female mice ( P<0.01). OLZ treatment could efficiently reverse the deficits on PPI by increasing PPI%( F(1, 165)=18.24, P<0.01), OLZ could reduce PPI score in male "dual-hit" model mice( F(1, 102)=21.81, P<0.01)and raise it in female( F(1, 102)=4.88, P<0.05). Conclusion:OLZ can reverse PPI deficits in schizophrenic neurodevelopmental model mice, and in the evaluation of PPI function in the model mice through PPI of acoustic startle reflex, PPI% has better stability and reactivity to OLZ intervention.

ABSTRACT
Histomonas meleagridis is a facultative anaerobic parasite, which can cause a common poultry disease known as histomoniasis. The species and age of the birds impacts on the susceptibility, with turkey being the most susceptible species. Chickens are less susceptible to H. meleagridis than turkeys and usually serve as reservoir hosts. Here, the diagnosis of an outbreak of histomoniasis in backyard Sanhuang chickens is described. The primary diagnosis was made based on clinical symptoms, general changes at necropsy, histopathology, and the isolation and cultivation of parasites. The pathogen was further confirmed by cloning, PCR identification, and animal inoculation tests. A strain of H. meleagridis, named HM-JSYZ-C, with a higher pathogenicity level in chickens was obtained. The study lays a foundation for further investigations into H. meleagridis and histomoniasis in chickens.

ABSTRACT
Objective To explore the correlation of circRNA expression level in peripheral blood and severity of cognitive dysfunction of major depressive disorder(MDD). Methods Gene chip technique was performed in peripheral blood mononuclear specimen from 5 MDD patients and 5 controls respectively for confirming circRNAs of aberrant expression,and further verification was done in a larger sample of 100 MDD patients by real-time fluorescence quantitative PCR,and all of MDD patients and controls were assessed by Montreal Cognitive Assessment-Beijing Version ( MoCA). Results Compared with the controls, scores of visuospatial & executive function, attention & computation, abstraction, delayed memory were significantly lower in MDD patients (t=-3. 89--1. 91,P<0. 05). Expression level of circRNA_002143 had negative cor-relation with attention & computation(r=-0. 645,P<0. 01 ). In MDD patients,expression levels of circRNA_103636,circRNA_100679,circRNA_104953 were positively correlated with visuospatial & executive func-tion,attention & computation,abstraction,delayed memory(r=0. 462-0. 589,P<0. 05 or 0. 01). Expression level of circRNA_100679,circRNA_104953 had predictive effect on visuospatial & executive function(t=9. 49,9. 31,P<0. 01) and accounted for 29. 0% of variances and circRNA_104953 had predictive effect on abstraction(t=8. 22,P=0. 009) and accounted for 28. 5% of variances. ROC analysis suggested expression levels of circRNA_103636,circRNA_100679,circRNA_104953 had neutral predictive efficacy on cognitive function(0. 7<AUC<0. 9,P<0. 05). Conclusion Cognitive dysfunction is specific feature of MDD,which can be interpreted by expression levels of circRNA_103636,circRNA_100679,circRNA_104953,and circR-NAs may regulate the pathological process of MDD via impairing the cognitive function.

OBJECTIVE To identify differentially expressed microRNA (miRNA) in peripheral blood mononuclear cells (PBMCs) of anxiety patients and predict their target genes and function by bioinformatics analysis. METHODS The miRNA expression profiles were determined using an Affymetrix array. To validate the results, real-time quantitative polymerase chain reaction (qRT-PCR) analysis in a larger cohort was employed. The targets of the differentially expressed miRNAs were predicted by Target Scan, miRBD, and DIANA-microT-CDS, and the results were analyzed by gene ontology (GO) and KEGG pathway analysis using FunNet. RESULTS MicroRNA microarray chip analysis has identified 7 miRNAs were detected with significant changes in expression in PBMCs of anxiety patients. qRT-PCR analysis has confirmed that the expression levels of 5 miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) were up-regulated. Intersecting the genes by Target Scan, miRBD, and DIANA-microT-CDS has predicted 195 targets. GO analysis showed that biological processes regulated by the predicted target genes have included diverse terms. Some terms, e.g., nervous system development, nerve growth factor receptor signaling pathway, neuron migration, dendrite development, regulation of neuron projection development, midbrain development, regulation of excitatory postsynaptic membrane potential, gliogenesis, dendrite morphogenesis, etc. have direct relationship with the central nervous system and brain functions. Pathway analysis showed that a significant enrichment in several pathways related to neuronal brain functions such as glutamatergic synapse, axon guidance, calcium signaling pathway, MAPK signaling pathway, GnRH signaling pathway, Wnt signaling pathway, gap junction, long-term potentiation and VEGF signaling pathway, etc. Among the five microRNAs, has-miR-4484, has-miR-4505, has-miR-4674 and has-miR-501-3p may have more important regulatory functions. CONCLUSION Five miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) are up-regulated in PBMCs of anxiety patients and may be closely involved in the pathogenesis of anxiety disorder.

ABSTRACT
Objective: To explore the relationship of trait anxiety, gender difference and risk averse. Methods: A test was conducted fwstly in 328 college students with the State-Trait Anxiety Inventory. The participants with a score≥53 were termed as high trait-anxiety group (N=30), in contrast to the former, the par-ticipants with a score ≤ 30 were treated as the low trait-anxiety (N=30) . The material was 10 hypothesized risk settings, asking the participants to do decision-making, at the same time, the participants were also required to ac-cess their subjective cost if the result of their decision was negative; recording the scores and the reaction time of the participants. Results: The risk-avoidant score in high trait-anxiety group was significantly higher than that in low trait-anxiety group [(5.97±1.53) vs.(3.27±1.25), P <0.01], and the risk-avoidant score in males was sig-nificantly higher than that in females [(2.78±1.37) vs.(6.46±1.26), P <0.01] .There also had significant interaction effects between the 2 variables (F=7.43, P <0.01). The reaction time in males was also longer than that in females [high-trait anxiety: (1586.47±10.352)vs.(1067.52±18.468); low-trait anxiety: (643.46±36.759)vs.(498.36±9.673); P < 0.01] . The correlation between subjective loss and trait-anxiety in females was higher than that in males (Z=2.15, P<0.05) . Conclusion: There is significant effect of trait-anxiety and gender difference on risk-avoidant decision-making. The high-trait and female individuals have more risk-avoidant in decision-making.
