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 investigate diagnostic and prognostic significance of protein C in acute leukemia with disseminated intravaseular coagnlation(DIC). Methods APTT, P-T, D-Dimer, Fbg, antithrombin (AT) and protein C(PC) were determinated in plasma of 44 DIC patients with acute leukemia and 30 normal controls. Results PC was markedly lower in disseminated intravaseular coagulation with acute leukemia group(67.03±36.98) than that of control group (99.53±45.20), and significantly correlation DIC score( r = -0.57,P＜0.01). PC of abnormality rate in DIC group was 86.36 %. APTT, PT, D-Dimer, Fbg were significantly increased and AT was decreased during the progress of DIC in relation to values observed in the control group. Conclusion DIC is related to the disorder of coagulation and fibfinolysis system. PC is a sensitive index to diagnose and prognose DIC in acute leukemia.

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 understand the stomatological development and structure of stomatological nursing condition,to provide references for the stomatological nursing development.Methods A status survey on stomatological nursing human resources and professional development was carried out.834 stomatological nurses in 120 counties were involved,2700 questionnaires were sent out,2512 copies were recovered.Results 465 nurses were employed by the stomatological institutions.Staff with professional titles as nurse accounted for 58.5％,with college degrees accounted for 82.4％.60.0％ of the nurses did not get any professional training in dentistry,72.0％ of the medical agencies did not have any nurses.The stomatological development was directly affected by local economy condition.Conclusions The stomatological nursing development lagged far behind in Yunnan province.Medical institutions and administrative departments need pay more attention to stomatological nursing development.And medical workers should also transform their ideas.

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 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 understand the current status and influencing factors of patient perception for humanistic care in China hospitals,and to provide a basis for developing nursing humanistic care measures and improving the quality of nursing humanistic care services.Methods A total of 30,099 outpatients and inpatients from 107 hospitals in 30 provinces(autonomous regions and municipalities)from July to August 2022 as survey subjects.A general information questionnaire and the Relational Caring Questionnaire-Patient Form were used for a cross-sectional survey,and a single-factor analysis was used to analyze the influencing factors of patient relationship care.Results Finally,29 108 valid questionnaires were collected,and the effective questionnaire recovery rate was 96.7％.The patient evaluation of relationship care was(65.72±8.61)points.Single-factor analysis showed that gender,age,marital status,children's situation,education level,occupation,place of residence,average family income,medical insurance type,visiting department,and location of the visiting hospital,and whether or not surgery were influencing factors of patient relationship care(P＜0.05).Conclusion The evaluation score of caregiver-patient relationship care among Chinese hospital patients is above average,but there is still room for improvement in western and rural regions,seriously ill and outpatient patients,low-income and low-medical insurance reimbursement populations,and non-surgical patients.Medical institutions at all levels should optimize and improve nursing humanistic care services based on influencing factors,and further enhance patients'perception of nursing humanistic care.
