Objective To investigate the expression of Kuppel-like factor 2( KLF2 )after focal cerebral ischemia-reperfusion( I/R)injury in rats and the intervention effect of nuclear factor kappa B ( NF-κB)inhibitor. Methods Sixty healthy male SD rats were randomly divided into a sham operation group,an I/R group,and a NF-κB inhibitor group( n=20 in each group). A focal cerebral I/R model was induced by the intraluminal suture method,and NF-κB inhibitor( pyrrolidinedithio carbamate,PDTC)was given to intervene. The observation time points were 6,12,24,and 48 hours after I/R. Reverse transcription-polymerase chain reaction(PCR)and Western blot were used to measure KLF2 mRNA and protein expression in ischemic brain tissue. Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of serum tumor necrosis factorα( TNF-α),and they were compared among groups. Results Compared with the sham operation group,the expression levels of KLF2 mRNA and protein in I/R group in the ischemic brain tissue at each time point were averagely decreased( the relative expression levels of KLF2 mRNA:0. 46 ± 0. 03 vs. 0. 82 ± 0. 04,0. 30 ± 0. 04 vs. 0. 78 ± 0. 05,0. 18 ± 0. 04 vs. 0. 76 ± 0. 02,0. 26 ± 0. 02 vs. 0. 81 ± 0. 04,respectively;the relative expression levels of KLF2 protein:0. 46 ± 0. 04 vs. 0. 80 ± 0. 02,0. 30 ± 0. 02 vs. 0. 79 ± 0. 02,0. 15 ± 0. 02 vs. 0. 77 ± 0. 01,0. 24 ± 0. 01 vs. 0. 79 ± 0. 02,respectively). They reached the lowest values at 24 hours after I/R,while the serum TNF-αlevels were increased. There were significant differences(all P<0. 05). After giving NF-κB inhibitor PDTC,the expression levels of KLF2 mRNA and protein at 6,12,24,and 48 hours after I/R were upregulated differently compared with the I/R group. The relative expression levels of KLF2 mRNA were 0. 61 ± 0. 04,0. 44 ± 0. 03,0. 34 ± 0. 02,and 0. 43 ± 0. 04, respectively. Those of KLF2 protein were 0. 60 ± 0. 02,0. 43 ± 0. 02,0. 33 ± 0. 01,and 0. 44 ± 0. 03, respectively,while the levels of TNF-αwere decreased. There were significant differences(all P<0. 05). There was a negative correlation between the KLF2 mRNA levels and the serum TNF-αlevels at each time point in the I/R group and the PDTC group( r= —0. 728 ,P<0. 05 ). Conclusions The expression levels of KLF2 mRNA in brain tissue are decreased after I/R,and it is negatively correlated with the serum TNF-α levels. It may be involved in the pathological process of I/R by NF-κB pathway mediated inflammatory reaction.

Objective To investigate protective effects of thrombopoietin ( TPO) on cerebral model control in rats and associated signal transduction pathway. Methods Thread embolism was performed to generate cerebral ischemia-reperfusion rat model. Eighty male SD rats were randomly divided into sham operation group, model control group, TPO group, TPO and Janus kinase 2 ( JAK2 ) kinase inhibitor ( AG490 ) group. Before 30 min of ischemia-reperfusion, TPO group was given TPO (5 μg·kg-1) by intraperitoneal injection, TPO + AG490 group was given TPO (5 μg·kg-1) before 30 min of ischemia reperfusion, then given AG490 (8 μg·kg-1), and model control group were given the same dose of 0. 9% sodium chloride solution. The observation time points were 6, 12, 24, and 48 h after ischemia reperfusion. Immunohistochemical staining and Western blotting were used to measure the protein levels of Bcl-2, JAK2 and signal transducer & activator of transcription (STAT3). TdT-mediated dUTP nick end labeling (TUNEL) was used to detect apoptosis. Results Compared with model control group, the number of apoptotic cells were significantly reduced [(67. 50±9. 37) vs. (40. 20±7. 47)], the expression levels of Bcl-2, JAK2 and STAT3 protein were significantly increased [(35. 40±7. 39) vs. (78. 70±9. 75);(35. 68±6. 75) vs. (62.35±7.53); (25.40±9.45) vs.(55.36±9.69), respectively] 24 h after ischeia reperfusion in the TPO group (all P<0. 05). Compared with the TPO group, the Bcl-2, JAK2 and STAT3 protein levels were significantly decreased in TPO and AG490 group [(78. 70±9. 75) vs. (55. 40±9. 35);(62. 35±7. 53) vs. (40. 68±5. 89); (55. 36±9. 69) vs. (30. 40±9. 39), respetively], and the number of apoptotic cells was significantly increased [(40. 20±7. 47) vs. (55. 23±7. 65)] (all P<0. 05). Conclusion TPO can inhibit cell apoptosis after ischemia-reperfusion injury, the mechanism might be related to the activation of JAK2/STAT3 signal transduction pathway through raising the expression of Bcl-2 gene.

Objective:To investigate the distribution and drug resistance of pathogens causing blood stream infection in patients with pancreatic neoplasms.Methods:Clinical data of patients with pancreatic neoplasms complicated with bloodstream infection with confirmed pathological evidence admitted in the First Affiliated Hospital of Naval Medical University from January 2016 to June 2019 were collected. Bacteria were isolated from blood culture, and microbial sensitivity tests were analyzed by minimum inhibitory concentration and Kirby-Bauer methods. The distribution and drug resistance of pathogens causing blood stream infection in patients with pancreatic neoplasms were analyzed.Results:There were 116 cases (8.5%) with bloodstream infection in 1 372 patients with pancreatic neoplasms. A total of 156 bacterial strains were isolated from blood culture, of which 127 strains (81.4%) were gram negative aerobic bacteria, mainly including Escherichia coli (42 strains), Klebsiella pneumoniae (34 strains), Pseudomonas aeruginosa (12 strains), and 25 strains (16.0%) were gram positive aerobic bacteria, mainly including Enterococcus faecium (11 strains), Enterococcus faecalis (3 strains), Streptococcus angina (3 strains). 4 strains (2.6%) were anaerobic bacteria. The results of antibiotic susceptibility showed that the resistance rate of Escherichia coli to ampicillin was 90.5%, and to cefoperazone-sulbactam was 2.4%. The resistance rate of Klebsiella pneumoniae to piperacillin was 20.6%, and to cefoperazone-sulbactam was 5.9%. The resistance rate of Pseudomonas aeruginosa to imipenem was 41.7%, and no resistant strain was found to cefoperazone-sulbactam. The resistance rate of Enterococcus and Streptococcus pharyngitis to erythromycin were 85.7% and 33.3%, and no strains were resistant to vancomycin.Conclusions:The rate of blood stream infection in patients with pancreatic neoplasms was relatively high. In clinical practice, the distribution of pathogenic bacteria should be understood, the drug resistance should be monitored and antibiotics should be reasonably used, in order to maximally prevent and interfere with the occurrence of blood stream infection.

Objective:To investigate the clinical characteristics of acute ischemic stroke with anterior circulation large vessel occlusion caused by cardioembolism (CE) and large artery atherosclerosis (LAA) and the efficacy of endovascular treatment.Methods:Patients with acute ischemic stroke caused by large vessel occlusion in anterior circulation and received endovascular treatment in the Stroke Center of the 971 st Hospital of the PLA Navy from April 2014 to April 2021 were retrospectively enrolled. The etiological classification of stroke was CE or LAA. According to the modified Rankin Scale score at 90 d after onset, the patients were divided into good outcome group (0-2) and poor outcome group (>2). The demographic and clinical data between the groups were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results:A total of 106 patients were enrollded. Their age was 61.39±13.73 years and 70 (66.0%) were males. Seventy-four patients (69.8%) were in the CE group and 32 (30.2%) were in the LAA group. Sixty-six patients (62.3%) had good outcomes. Univariate analysis showed that there were significant differences in gender, age, smoking, systolic blood pressure, diastolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) score, time from onset to femoral artery puncture, time from puncture to vascular recanalization, and the number of retrieval attempts between the CE group and the LAA group (all P<0.05), and there were no significant differences in the incidences of poor outcome, hemorrhagic transformation, and symptomatic intracranial hemorrhage. There were significant differences in systolic blood pressure, diastolic blood pressure, baseline NIHSS score, time from onset to femoral artery puncture, and blood perfusion grade after treatment between the good outcome group and the poor outcome group (all P<0.05). Multivariable logistic regression analysis showed that higher systolic blood pressure (odds ratio [ OR] 1.046, 95% confidence interval [ CI] 1.014-1.078; P=0.004), higher baseline NIHSS score ( OR 1.117, 95% CI 1.037-1.203; P=0.003), longer time from onset to femoral artery puncture ( OR 1.008, 95% CI 1.001-1.015; P=0.019) and poor blood perfusion after treatment ( OR 8.042, 95% CI 1.532-42.215; P=0.014) were significantly and independently associated with the poor outcomes. Conclusions:Compared with LAA, CE do not increase the risks of hemorrhagic transformation and symptomatic intracranial hemorrhage. The safety and efficacy of the two are similar.
