Objective To explore the personality change in patients with epilepsy during the interictal period and the correlation between clinical features and personality change. Methods One hundred and fifteen patients with idiopathic or cryptogenic epilepsy were chosen as the epileptic group and 42 age- and sex-matched healthy subjects served as controls. All participants were evaluated by Mini Mental Status Examination and Brief Psychiatric Rating Scale to ensure the normality of cognition and mental state.Personality was evaluated by adult version of Eysenck Personality Questionnaire (EPQ)in interictal epilepsy patients and healthy controls.Scores of psychoticism (P),extraversion (E),neuroticism (N) and lie (L)were obtained using computer software. Pearson correlation analysis and logistic regression were used to investigate the scores of EPQ and influential factors.Results P and N scores were significantly elevated in epilepsy patients compared with controls ( P scores:50.48 ± 9.55 vs 46.59 ± 7.28,N scores:51.13 ±12.89 vs 46.83 ± 9.40 ; t =2.374,2.266,both P ＜ 0.05 ),while E scores were significantly decreased (51.74 ± 10.74 vs 60.37 ± 9.84;t =- 4.511,P ＜ 0.01 ).There were no significant differences in L scores.Multivariate analysis showed that disease duration was independently correlated to P scores (β =0.043,P＜0.05),while education was correlated to E scores (β =0.109,P ＜ 0.05 ).There were no significant correlations between personality scores,patient age,gender,age of onset,frequency,seizure type,National Hospital Seizure Severity Scale scores,family history,history of status epilepticus and antiepileptic drugs usage.Conclusions High psychoticism and neuroticism and low cxtraversion scores are correlated to patients with epilepsy during the interictal period.Disease duration is an independent risk factor for psychoticism personality,and education level is an independent risk factor for extraversion personality in epilepsy patients.

Objective To evaluate cerebral parenchymal atrophy of patients with Alzheimer's disease(AD)through the compara-tive analysis of the volume and morphology of the brain ventricle between patients with AD and normal elderly.Methods 20 patients with AD and 20 normal elderly people were scanned at 3.0T MR,and lateral ventricle section images were achieved,and the lateral ventricle volume and the anterior horn,posterior horn and temporal horn of the lateral ventricle were calculated by analyzing the re-construction of section images with MIMICS software from Belgian.Results As compared with normal elderly group,the patients with AD exhibited significantly increased the volume of left ventricular volume(LV),right ventricular volume (RV)and total vol-ume (TV)(P<0.05).Angle of bilateral anterior horn and temporal horn but not posterior horn of the lateral ventricle in patients with AD were significantly higher than that in normal elderly (P<0.05).The volume of the left,right and total cerebral ventricle, the angle of the anterior horn of the left and right lateral ventricle and the angle of the temporal horn of the left and right lateral ven-tricle were negatively correlated with MMSE (P<0.05).Conclusion Patients with AD exhibites significantly greater volume and an-gle of the lateral ventricular than normal elderly people.These related data measured can predict brain parenchymal atrophy of pa-tients with AD more conveniently and accurately.

BACKGROUND:Bismth-doped iron nanoparticles modified by hyaluronic acid (HA-BiIOPs) not only act as an effective MRI contrast agent, but also as a radiotherapy sensitizer.OBJECTIVE:To fabricate the HA-BiIOPs and to observe its effect to enhance the radiosensitivity of glioblastoma cells U87MG under X-ray radiation.METHODS:HA-BiIOPs were synthesized using hydrothermal polyol method. (1) Cytotoxicity: A cytotoxicity test was carried out on U87MG cells and rat vascular smooth muscle cells (VSMCs). Cell proliferation rate of two kinds of cells cultured with different concentrations of HA-BiIOPs (0, 12.5, 25, 50, 100, 200, 400 mg/L) at 24 hours after culture were determined by cell counting kit-8 assay. (2) Histological analysis: ICR mice were sacrificed after intravenous injection of HA-BiIOPs, and pathological changes of mouse visceral organs were observed under an optical microscope. (3) Cellular uptake: The HA-BiIOPs after entered into the cytoplasm were observed by Prussian blue staining. (4) Radiosensitization test: U87MG cells at Logarithmic growth stage were cultured in culture medium as control group, subjected to X-ray irradiation (0, 3, 6, 9 Gy) as radiotherapy group, cultured in HA-BiIOPs (0, 12.5, 25, 50, 100, 200 and 400 mg/L) as HA-BiIOPs group or subjected to HA-BiIOPs culture plus X-ray irradiation as combined therapy group. Then, the cell proliferation rate and cloning efficiency were measured at 24 hours after treatment.RESULTS AND CONCLUSION:(1) The HA-BiIOPs at different concentrations were non-cytotoxic for VSMC and U87MG cells. (2) After intravenous injection of HA-BiIOPs, there was no obvious toxicity to the mouse susceptible organs. (3) After 6 hours of culture, the HA-BiIOPs could be internalized by U87MG cells. (4) The proliferation rate of U87 cells was negatively correlated with the concentration of HA-BiIOPs (0-200 mg/L) and X-ray dose (0-9 Gy). Especialy, the combination of 6 Gy X-ray irradiation with 200 mg/L HA-BiIOPs dramatically decreased the cell viability that was decreased to (41±7)%. In the combined therapy group with 6 Gy X-ray and 100 mg/L HA-BiIOPs, the cells proliferation rate was significantly lower than that in the control and radiotherapy groups (P < 0.05). These results indicate that HA-BiIOPs have a radiosensitizative effect on glioblastoma cells U87MG.

BACKGROUND: Both therapeutic effects of stem cell transplantation and differentiation mechanism remain controversial;however, plentiful clinical studies have indicated that stem call transplantation might improve heart function.OBJECTIVE: To evaluate the efficacy of intracoronary autologous bone marrow mononuclear call transplantation for the treatment of chronic heart failure.DESIGN: Case analysis. PARTICIPANTS: A total of 80 patients with chronic heart failure who were selected from Henan People's Hospital from 2003 to 2008 were divided into two groups: autologous bone marrow mononuclear call transplantation group (n=48) and conventional drug therapy group (n=32). There were no significant differences in sex, age, accepting conventional drug therapy,echocardiogram before transplantation, plasma brain natriuretic peptide level, and myocardial perfusion imaging between the two goups (P>0.05).METHODS: A one-year following up before and after cell transplantation, conventional drug therapy was performed in the two groups. Based on conventional drug therapy, autologous bone marrow mononuclear call suspension (10 mL) was slowly poured into coronary artery, and the cell number was adjusted to (3.1±1.6)×10 8. MAIN OUTCOME MEASURES: Changes of heart function were measured using ultrasound apparatus; plasma brain natriuretic peptide levels were detected using double antibodies immumofluorescence method; area of myocardial perfusion defect region was detected using single photon emission computed tomography.RESULTS: Patients in the two groups finished the one-year follow-up, and adverse effects and complications were not found before and after cell transplantation. ①Compared to before cell transplantation, end-systolic volume (ESV) of the left ventricle was significantly decreased in the autologous bone marrow mononuclear cell transplantation group after one year (P < 0.05), but ejection fraction (EF) of the left ventricle was significantly increased (P < 0.05). However, both ESV and EF were not changed in the conventional drug therapy group (P> 0.05). Compared to conventional drug therapy group, ESV and EF were changed significantly in the autologous bone marrow mononuclear call transplantation group after one year (P < 0.05). ②Compared to before cell transplantation, plasma brain natriuretic peptide levels were significantly decreased in the two groups (P < 0.05 or 0.01). Area of myocardial perfusion defect region was significantly decreased (P < 0.05 or 0.01), and the area change in the autologous bone marrow mononuclear call transplantation group was significantly greater than conventional drug therapy group (P < 0.05).CONCLUSION: Autologous bone marrow mononucleer call transplantation is safe and feasible for the treatment of chronic heart failure, and it also can remarkably improve heart function and myocardial perfusion within one year.

Objective To investigate the practical value of a logistic regression model of serum indexes in distinguishing between geriatric depression and geriatric depressive state. Methods A total of 160 patients were recruited from the outpatient department from January 2013 to January 2016 ,and were divided into a depression group (n= 80)and a depressive state group (n= 80) ,with retrospective diagnoses based on the Chinese Classification of Mental Disorders-Third-Edition(CCMD-3).Serum samples were collected and enzyme linked immunosorbent assays (ELISA)were used to determine the concentrations of brain-derived neurotrophic factor (BDNF ) ,glial cell line-derived neurotrophic factor(GDNF) ,fibroblast growth factor 2(FGF-2) ,vascular endothelial growth factor (VEGF) ,interleukin-1β(IL-1β) ,interleukin-6 (IL-6) ,interleukin-10 (IL-10) ,tumor necrosis factor-α(TNF-α) ,cortisol (CORT ) ,and platelet-derived growth factor (PDGF).Binary logistic regression analysis was used to establish the regression model ,and the ROC curve was drawn to explore its value of differentiating geriatric depression from depressive state. Results The levels of serum BDNF , GDNF and VEGF in the depression group were lower than those in the depressive state group (BDNF :208.7 ± 41.4 vs.262.9 ± 84.6 ng/L ,GDNF :92.3 ± 18.6 vs. 101.4 ± 30.9 ng/L ,VEGF :223.1 ± 98.2 vs. 257.8 ± 77.2ng/L) ,while the levels of IL-1βand CORT in the depression group were higher than in the depressive group(IL-1β:27.0 ± 4.9 vs.19.6 ± 5.7 μg/L ,CORT :96.3 ± 16.7 vs.83.0 ± 17.3 nng/L).In multivariate logistic regression analysis ,BDNF(OR = 0.987 ,P = 0.001) ,IL-1β(OR =1.29 ,P = 0.000)and CORT (OR = 1.065 ,P = 0.000)were selected to build the regression model. The regression equation was P=1/[1+e-(- 8.546 - 0.013(BDNF)+ 0.258(IL -1β)+ 0.063(CORT)) ]and the area under the ROC curve was 0.966.Compared with retrospective diagnoses made two weeks later ,the correct diagnosis rate of the logistic model was 90.47％. Conclusions The Logistic regression model of serum indexes can further differentiate between geriatric depression and depressive state which also offers additional benefits for the diagnosis ,differential diagnosis ,and treatment of depression.

Objective To investigate the variation of serum fibroblast growth factor-22 (FGF-22) of first episode depressive patients before and after treatment,and its relations with serotonin (5-HT) and interleukin-1[β (IL-1β) levels and Hamilton's depression scale (HAMD) scores to provide assistance for further study of pathogenesis of depression.Methods Ninety patients with first episode depression accepted treatment in our hospital from June 2015 to June 2016 and 90 healthy controls were enrolled.The serum FGF-22 level was detected and Hamilton's depression scale (HAMD) was performed before and after drug treatment.The relations of FGF-22 level with 5-hydroxytryptamine (5-HT) and interleukin (IL)-1[β levels were analyzed.Results (1) Before treatment,the first episode depressive patients had significantly lower scrum FGF-22 level ([180.44±17.02] ng/mL) and statistically higher HAMD scores (17.84±5.92) as compared with the healthy controls ([200.74±16.63] ng/mL,1.88±2.67,P＜0.05).(2) The serum FGF-22 level after treatment ([195.74+19.57] ng/mL) was significantly higher than that before treatment,and the HAMD scores after treatment (7.64±4.09) were significantly lower than those before treatment (P＜0.05).(3) In the patient group,serum FGF-22 level and HAMD scores were negatively correlated (r=-0.644,P=0.000);serum FGF-22 level had positive correlation with 5-HT level (r=0.718,P=0.000),and negative correlation with IL-1β level (r=-0.763,P=0.000).Conclusion The serum FGF-22 level is abnormal in first episode depressive patients,and it could be a good indicator of peripheral blood in response to depression,which plays an important role in the pathogenesis of depression.

Objective To investigate the compliance of secondary prevention and the relationship with the long-term outcomes in patients undergoing percutaneous coronary intervention(PCI).Methods 589 patients undergoing PCI were followed-up,and factors including major adverse cardiac events(MACE)),smoking status and the usage of antiplatelet agents,angiotensin converting enzyme inhibitor(ACEI)/angiotensin Ⅱ receptor blocker(ARB),statins,beta blocker,calcium channel blocker and nitrates were recorded.Results The average follow-up time was 18.92 months.At discharge,588 patients(99.83%)were prescribed clopidogrel for(7.89±4.96)months;there were 31 patients(5.26%)who completely discontinued antiplatelet therapy during follow-up.At discharge,the prescription rate of aspirin,ACEI/ARB,beta blocker,statins,calcium channel blocker and nitrates was 98.98%,41.94%,63.50%,83.02%,19.69%and 46.52%respectively,whereas at follow-up,these were decreased to 94.4%,35.99%,55.86%,65.89%,17.49%and 35.31%.At follow-up,there were still 105 current smokers(17.83%).Complete cessation of antiplatelet therapy and current smoking were related to the increased risk of non-fatal myocardial infarct(9.68%v.s.1.08%,P＜0.01);smoking(4.76%v.s.0.83%,P＜0.01)andMACE(19.35%v.s.6.45%,P＜0.01);smoking(11.43%v.s.6.20%,P＜0.05).Conclusion Most patients can adhere to secondary prevention during follow-up,however,the compliance with secondary prevention should be improved further.Cessation of antiplatelet therapy and current smoking contribute to poor prognosis.

Objective:To compare the differences of event-related potential P300 and serum fibroblast growth factor 22 (FGF22) levels in cognitive impairment patients with first-episode and recurrent depression, and analyze the relations of each index with cognitive function and serum inflammatory factors.Methods:From June 2020 to April 2021, 45 cognitive impairment patients with first-episode depression (first-episode group) and 42 cognitive impairment patients with recurrent depression (recurrence group) were selected from our hospital. P300 examination was performed and serum FGF22, interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) levels were measured by enzyme-linked immunosorbent experiment (ELISA). The differences in clinical data, P300 examination results, and serum FGF22, IL-6 and TNF-α levels were compared between the two groups. The correlations of P300 amplitude and latency and serum FGF22 level with Montreal Cognitive Assessment (MoCA) scores and IL-6 and TNF-α levels were analyzed.Results:As compared with the first-episode group, the recurrence group had significantly decreased MoCA scores, P300 amplitude and serum FGF22 level, and statistically increased P300 latency and IL-6 and TNF-α levels ( P<0.05). Correlation analysis showed that P300 amplitude and serum FGF22 level were positively correlated with MoCA scores, and negatively correlated with IL-6 and TNF-α levels ( P<0.05); P300 latency was negatively correlated with MoCA scores, and positively correlated with IL-6 and TNF-α levels ( P<0.05). Conclusion:P300 amplitude and latency and serum FGF22 level are different between cognitive impairment patients with first-episode and recurrent depression, and they are correlated with the cognitive function and serum inflammatory factors.

Objective:To investigate the predictive values of serum fibroblast growth factor 22 (FGF22) levels and electrical P300 in depression patients occurred mild cognitive impairment (MCI).Methods:A prospective study was performed. A total of 94 depression patients without cognitive impairment admitted to our hospital from January 2020 to August 2021 were chosen. These patients were followed up for one year; Hamilton Depression Scale (HAMD)-24 items and Montreal Cognitive Assessment Scale (MoCA) were used to evaluate the neuropsychological function of the patients every 3 months; according to the occurrence of MCI, the patients were divided into depression with MCI group ( n=57), and depression without MCI group ( n=32). All patients underwent baseline P300 examination and baseline serum FGF22 levels were detected by enzyme-linked immunosorbent assay (ELISA), and the differences in clinical data, P300 examination results and serum FGF22 levels were compared between the two groups. Correlation analysis was performed to analyze the correlations of P300 latency and serum FGF22 level with MoCA scores. Multivariate Logistic regression analysis was used to screen the independent influence factors for MCI in patients with depression. The predictive value of P300 latency and serum FGF22 level in MCI in patients with depression was analyzed by receiver operating characteristic (ROC) curve. Results:As compared with the depression without MCI group, patients in the depression with MCI group had significantly lower years of education and serum FGF22 level, and significantly higher proportion of patients living alone, and statistically higher P300 latency ( P<0.05). The results of correlation analysis showed that the MoCA scores at MCI period were positively correlated with serum FGF22 level ( r=0.665, P<0.001) and negatively correlated with P300 latency ( r=-0.621, P<0.001) in patients from the depression with MCI group. Multivariate Logistic regression analysis showed that serum FGF22 level was a protective factor for MCI in patients with depression ( OR=0.805, 95%CI: 0.737-0.862, P=0.003), and P300 latency was a risk factor for MCI in patients with depression ( OR=1.136, 95%CI: 1.115-1.163, P=0.001). ROC curve analysis showed that the areas under the curve (AUC) of serum FGF22 level, P300 latency, serum FGF22 level combined with P300 latency in predicting MCI in depression patients were 0.779, 0.724, and 0.852, respectively. Conclusion:The abnormal serum FGF22 level and P300 latency are closely related to the occurrence of MCI in patients with depression, and the combination of the two can be used to predict the occurrence of MCI in patients with depression.

Objective:To examine the structural network changes in participants with amnestic mild cognitive impairment(aMCI)and investigate the correlation between these changes and the onset of Alzheimer's disease(AD).Methods:In this prospective study, a total of 100 individuals with amnestic mild cognitive impairment(aMCI)were enrolled as the research group.Additionally, 25 healthy individuals who were matched in terms of age and sex were enrolled as healthy controls.Upon enrollment, all participants underwent MRI scans, neuropsychological assessments, and clinical evaluations.The participants were then followed every 6 months for a period of 36 months or until they withdrew from the study.Based on the outcome of the follow-up(whether Alzheimer's disease occurred), the aMCI participants were divided into two groups: stable aMCI group and progressive aMCI group.The Chinese version of the Brief Mental State Examination(MMSE), the Montreal Cognitive Assessment(MoCA), the Clinical Dementia Rating Scale(CDR), and the Auditory Word Learning Test(AVLT)were utilized to evaluate the overall mental and cognitive status of the subjects.Pearson correlation analysis was employed to investigate the relationship between structural network changes and cognitive decline.Logistic regression was performed to analyze the predictive ability of structural network changes in determining the onset of AD.Results:Compared to the stable aMCI group, the progressive aMCI group exhibited lower levels of global efficiency( P=0.002), local efficiency( P=0.007), feeder connections( P=0.003), local connections( P=0.008), and right precuneus nodal efficiency( P=0.010).Correlation analysis revealed that global efficiency( r=0.604, P=0.002), feeder connections( r=0.513, P=0.012), and right precuneus nodal efficiency( r=0.504, P=0.014)were correlated with AVLT-delay scores(baseline)in the progressive aMCI group.A logistic regression model demonstrated that global efficiency, feeder connections, and right precuneus nodal efficiency could significantly predict the onset of AD(all P<0.05, AUCunited=0.797, 95% CI: 0.684-0.884, sensitivity=73.91, 95% CI: 51.6-89.8, specificity=76.60, 95% CI: 62.0-87.7). Conclusions:Among participants with aMCI, individuals who exhibit lower global efficiency, feeder connections, or right precuneus nodal efficiency are at a higher risk of developing AD.These indicators are anticipated to serve as new targets for clinical intervention.
