Objective To investigate the effect of Rho kinase inhibitor fasudil on taxed lineage kinase 3 (MLK3), c-Jun NH2-terminal kinase (JNK) phosphorylation, caspase-3expression, and neuronal injury in hippocampal CA1 region follwong cerebral ischemic rep erfusion in rats. Methods A total of 72 Sprague-Dawley rats were randomly divided into sham operation, ischemia-reperfusion, normal saline, and fasudil groups. A global cerebral ischemic model was prepared by four-vessel ligation. The levels of MLK3 and JNK phosphorylation, and caspase-3 expression were detected by Western blot analysis. Cresy1 violet staining was used to detect the numbers of survival neurons in hippocampal CA1 region. Results When 6 hours after ischemia-reperfusion, the level of MLK3 phosphorylation in the fasudil group (1.13 ± 0. 03)was significantly lower than that in the normal saline group (2. 08 ± 0. 01 ,P = 0. 000 3), while the levels of MLK3 was no significant difference. When 3 hours after ischemia-reperfusion, the level of JNK phosphorylation in the fasudil group (1.27 ±0. 02)was significantly lower than that in the normal saline group (2.09 ±0. 01, P=0. 000 2), while the levels of JNK was no significant difference. When 6 hours after ischemia-reperfusion, the expression level of caspase-3in the fasudil group (1.28 ± 0. 02) was significantly lower than that in the normal saline group (2. 10 ± 0. 01, P = 0. 000 6). When 5 days after ischemia-reperfusion, the pyramidal cells in hippocampal CA1 region almost completely disappeared in the ischemia-reperfusion group, and only a few cells left (9. 8 ±2. 1). The numbers of survival pyramidal cell (8. 28 ± 3.2) in hippocampal CA1 region in the fasudil group was significantly more than that in the normal saline group (11.8 ± 1.6, P <0. 05). Conclusions Fasudil may significantly inhibit the ischemia-reperfusion-induced phosphorylation of MLK3 and JNK, as well as the expression of caspase-3, and thus reduce neuronal injury in hippocampal CA1 region.

Objective To study the relationship between genetic polymorphisms of CYP2E1 and the susceptibility of the acute leukemia in Gansu population. Methods The C609T polymorphism of CYP2E1 gene was detected by polymerase chain reaction-ligase detection reaction (PCR-LDR) and 1∶1 matched casecontrol method in 100 healthy persons (control group) and 100 patients with acute leukemia (AL group).Results The C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AL group (13.5 % and 22 %, respectively) than those in control group (10.5 % and 19 %, respectively), however,both differences showed no statistical significant. Further stratified analysis, the C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AML group (27%) than that in control group (19 %), but difference had no statistical significant, too. The occurrence frequency of the C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene showed no significant difference in ALL group and control group (x2=0.446, P =0.504>0.05). Conclusion Genetic polymorphisms of CYP2E1 don't correlated to susceptibility of acute leukemia(AML and ALL) in Gansu population.

Objective To assess the clinical significance of detecting the immune markers in idiopathic thrombocytopenic purpura (ITP). Methods The frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombopoietin in 64 ITP patients and 31 healthy controls were measured with enzyme-linked immunospot assay (ELISPOT),modified monoclonal antibody immunobilization of platelet antigens assay (MAIPA), flow cytometry and sandwich enzyme-linked innnunosorbent assay respectively. Results Compared with the controls[1.3 ± 0. 5/105 peripheral blood mononuclear cell (PBMC), (0.33±0.06,0.41±0.03), (22.08±4.54)% and (8.19±2.46)%], the frequencies of circulating B cells secreting platelet-specific antibody (7.6±4.6/105 PBMC in acute ITP group, 5.3±3.0/105 PBMC in chronic ITP group), platelet-specific antibody (including the anti-GP Ⅱ b/Ⅲa antibody, anti-GP Ⅰ b/X antibody) (0.51 ±0.11, 0.48±0.06 in acute ITP group; 0.49±0.10,0.46±0.09 in chronic ITP group), the percentage of CD8+ T Lymphocyte (27.09±9.86 ) %, the percentage of reticulated platelet in ITP patients[the megakaryocyte cytosis group (24. 85 ± 19. 18)%, the normal megakaryocyte group (23.89±18.90)%]were significantly increased ( all P<0.05).The frequencies of circulating B cells secreting platelet-specific antibody in acute ITP patients were notably increased (P<0.05) compared to the chronic ITP patients. In T lymphocyte subsets, the percentage of CD3+T lymphocyte and CD4+ T lymphocyte and the ratio of CD4+/CD8+ in the patients with ITP[(60.88±14.59)%, (28.41±10.55)%, 1.18±0.59]were notably decreased than those in the healthy controls [(69.89±6.43)%, (35.38±5.05) %, 1.64±0.29, P<0.05]. There was no apparent difference of the level of thrombopoietin between ITP patients with megakaryocyte cytosis (72. 09 ± 41.64 ) and health controls (75.37± 26. 32, P > 0. 05 ), however, the level of thrombopoietin of ITP patients with normal megakaryocyte apparently increased (118.60±70.72, P<0.05). Conclusion Detecting the frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombepoietin in the patients with ITP may improve the diagnosis and guide clinical therapy.

ObjectiveTo review the efficacy and safety in secondary prevention of ischemic stroke with cilostazol or aspirin.Methodswe searched Cochrane Library(the 4th issue, 2009 ), PubMed(1980.1~2009.11), EMBASE(1980.1~2009.11), CBM(1978.1~2009.11), CNKI(1979.1~2009.11) and some other databases, then collected all of the studies describing the outcomes in curing the ischemic stroke after taking cilostazol or aspirin. According to the strict inclusion and exclusion criteria, two reviewers independently selected trials, extracted datas, made cross-checking and methodological quality assessment of the homogeneity studies by using the Cochrane systematic review methods, then made Meta analysis using RevMan 5.0 software.ResultsThis systematic review study included two randomized controlled trials and a cross-over trial, which contained a total of 838 participants. The evidence quality of one of the randomized controlled trials was high, however, the evidence quality of another randomized controlled trial and the cross-over trial was poor. Meta analysis results suggested that the effectiveness of cilostazol and aspirin in the secondary prevention of ischemic stroke performed no significantly statistical difference: primary endpoint(30 d[RR=3.00, 95%CI(0.31,28.70)]; 90 d[RR=1.67, 95%CI(0.40,6.92)]; 180 d[RR=1.25, 95%CI(0.50, 3.13)]; 360 d[RR=0.65, 95%CI(0.33, 1.29)]; 540 d[RR=0.80,95%CI(0.54, 1.18)]); combined endpoint(30 d[RR=4.00, 95%CI(0.45,35.61)]; 90 d [RR=1.75,95%CI(0.52,5.93)]; 180 d[RR=1.00, 95%CI(0.48, 2.07)]; 360 d [RR=0.77, 95%CI(0.45, 1.29)]; 540 d[RR=0.66,95%CI(0.40,1.09)]); the recurrence of ischemic stroke: cilostazol group: RR=0.64, 95%CI(0.31,1.30),aspirin group: RR=0.21, 95%CI(0.04,1.06); PDMP[RR=1.00, 95%CI(0.39, 2.58)]. But in terms of the probability of intracranial hemorrhage ([RR=7.14, 95%CI(0.7,58.33)]) and other safety standards, taking cilostazol performed lower than taking aspirin.ConclusionThe side effects of cilostazol and aspirin in the treatment for ischemic stroke were similar to each other, but in terms of the probability of dizziness, headache, tachycardia and palpitation, taking cilostazol performed higher than taking aspirin, however, taking cilostazol performed lower in the probability of intracranial hemorrhage and other organ hemorrhage than taking aspirin. Since this study included a small amount of studies, in which the evidence quality of one of the randomized controlled trials and the cross-over study was poor, therefore, it would be necessary to make a further validation with lots of high-quality clinical trials.

Objective:To investigate the work engagement among nurses in stomatology hospital and to analyze its influencing factors.Methods:From September 2018 to October 2018, we selected 229 medical and nursing personnel from a Class Ⅲ Grade A public stomatology hospital as the research object by convenience sampling. All medical and nursing personnel were investigated with the self-designed Work Engagement Scale for Dental Specialist Outpatient Nurses to analyze the current status and influencing factors of work engagement among outpatient nurses in stomatology hospital.Results:134 doctor questionnaires were distributed and 126 valid questionnaires were returned; 113 nurse questionnaires were distributed and 103 valid questionnaires were collected.Totals of 50.8% (64/126) of doctors and nurses were reasonably staffed; 45.6% (47/103) of nurses were satisfied with the professional status and development. The three items with the highest engagement evaluated by doctors included mixing materials, use of instruments and disinfection of products after use; the three items with the lowest engagement evaluated by doctors were medical record data management, assisting doctor-patient communication and return visits. Univariate analysis showed that there was a statistical difference in the engagement among nurses with different departments ( P<0.05) . Correlation analysis indicated that the staffing status of nurses is positively correlated with the clinical cooperation of nurses and the degree of participation in hospital prevention and control ( P<0.05) ; the professional status and development of nurses are positively correlated with the degree of patient participation management ( P<0.05) ; the degree of salary satisfaction is positively correlated with the degree of patient participation and clinic management. Conclusions:Nurses of public stomatology hospital have low overall work engagement during diagnosis and treatment for patients. We need to strengthen dental nursing training. Nurse staffing in place and perfecting performance evaluation methods can promote nurses to fully perform their duties and promote the improvement of patient safety.

Objective:To investigate the underlying neuroimaging mechanism of migraine without aura (MwoA) by using methods of voxel-based morphometry (VBM) and resting-state functional connectivity (FC).Methods:Twenty-five MwoA patients admitted to Department of Neurology, the Second Affiliated Hospital of Xuzhou Medical University from September 2020 to June 2023 were recruited as MwoA group, and 22 volunteers were recruited as healthy control (HC) group. Demographic, clinical characteristics, scores of Hamilton Anxiety Scale (HAMA), Hamilton Depression Rating Scale (HAMD) and Montreal Cognitive Assessment (MoCA) of all subjects were collected; MwoA patients also received Migraine Disability Assessment Questionnaire, Headache Impact Test-6 and headache Visual Analogue Scale assessments. All subjects underwent high-resolution 3D-T 1 and resting-state functional magnetic resonance imaging scanning. The SPM12 software was used to compare the difference in gray matter volume (GMV) between the 2 groups by VBM method. The GRETNA software was adopted to calculate the whole brain FC with anatomical automatic labeling 90 as the regions of interest, and the difference in FC between the 2 groups was statistically analyzed by two-sample t-test. Pearson partial correlation was used to analyze the correlation between brain GMV and FC changes and clinical features and scale scores of MwoA patients. Results:There existed no statistically significant difference between the 2 groups in age, gender, education, scores of HAMA, HAMD and MoCA (all P>0.05). Migraine Disability Assessment Questionnaire, Headache Impact Test-6 and headache Visua Analogue Scale scores of MwoA patients were (8.86±4.55), (50.27±6.35) and (6.68±1.73). Compared with the HC group, GMV was significantly decreased in the right superior frontal gyrus (SFG), right cingulate gyrus (CG) and left thalamus in the MwoA group ( P<0.05, false discovery rate corrected). In addition, the MwoA group showed decreased FC between left thalamus and right cuneus, left lingual gyrus (LG) and bilateral precuneus; decreased FC between right thalamus and right cuneus, right LG and right precuneus; decreased FC between right cuneus and left precuneus and right SFG; decreased FC between left LG and bilateral precuneus, decreased FC between right LG and right precuneus and left SFG; decreased FC between left precuneus and bilateral SFG, and between right precuneus and right SFG (edge P<0.001, component P<0.05, network-based statistics correction, interation=2 000). In MwoA patients, the FC (z-value) between left thalamus and right cuneus was negatively correlated with the duration of disease ( r=-0.530, P=0.011). Conclusions:MwoA patients showed decreased GMV in right SFG, CG and left thalamus. In MwoA patients, FC between thalamus and visual network (VN) and default mode network (DMN) was significantly decreased, and FC among VN, DMN and executive control network was significantly decreased. These changes in brain structure and function may be an adaptive change in the central sensitivity and responsiveness to pain stimuli, and may be an important neuroimaging mechanism of MwoA.

Objective:To investigate the differences in resting-state functional connectivity (FC) between patients with vestibular migraine (VM) and migraine without aura (MwoA) in order to infer the possible neuroimaging mechanisms of VM.Methods:Thirty VM patients admitted to the Department of Neurology of the Second Affiliated Hospital of Xuzhou Medical University from December 2019 to December 2022 were selected as the experimental group (EG) (6 males and 24 females, with mean age of 38.3 years) and 26 MwoA patients as the control group (7 males and 19 females, mean age 35.5 years). General demographic and clinical data such as gender, age, year of education, course of disease and frequency of attacks were collected for all the patients, as well as data of Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Montreal Cognitive Assessment (MoCA), headache Visual Arialogue Scale (VAS), Headache Impact Test 6 (HIT-6) and Migraine Disability Assessment Questionnaire (MIDAS). VM patients were also assessed by Dizziness Handicap Inventory (DHI), dizziness VAS and Vestibular Disorders Activities of Daily Living (VADL) scales. All patients underwent resting-sate functional Magnetic Resonance Imaging (fMRI) scans. Bilateral parietal opercular cortex 2 (OP2) and primary visual cortex (V1) were used as regions of interests (ROIs). Differences in FC between ROIs and other brain regions were calculated between the two groups. In view of the brain regions with significant differences, z-values of FC were extracted for each subject in the EG, and Pearson partial correlation analysis was conducted between z-values of FC and clinical characteristics of patients, P<0.05 was considered to have significant correlation. SPSS 22.0 was used for statistical analysis. Results:There was no significant difference in gender, age, years of education, course of disease, frequency of attack and scores of MoCA, HAMA and HAMD between the two groups ( P>0.05). Headache VAS, HIT-6 and MIDAS scores in VM patients were significantly lower than those in MwoA patients ( P<0.05). Compared with MwoA patients, the FC between left OP2 and bilateral precuneus and left thalamus was significantly increased in VM patients, and the FC between right OP2 and left thalamus and right anterior cingulate gyrus were significantly increased ( P<0.05, False Discovery Rate correction). Correlation analysis showed that the FC between left OP2 and left precuneus was positively correlated with DHI score in VM patients ( P=0.007, r=0.480), and the FC between right OP2 and left thalamus was positively correlated with the disease course in VM patients ( P=0.015, r=0.439). Conclusions:The pathogenesis of VM may be related to the altered FC of vestibular, pain and visual-motor networks, abnormalities of these neural pathways may be important imaging biomarkers of VM pathogenesis.
