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 explore the effect of quality control circles (QCCs) in improving the delivery health checkup report.Methods QCC was founded with the theme of"improving the quality of health checkup report delivery."First,we planned an activity schedule and identified topics.We then set target focuses for service personnel,distribution modes,and operating environments;planned countermeasures;and selected optimal policies.Circle members implemented the optimal policies jointly.Reports of physical examinations by the Guoyu health management center were selected and analyzed.The total number of reports before improvement (January to December 2015) was 59 189 of which 34 549 (58.4％) were male patients and 24 640 (41.6％) were female patients;their average age was (37.7± 11.4) years.The total number of reports after improvement (December 2016 to January 2017) was 6 568,of which 3 881 (59.1％) were male patients and 2 687(40.9％) were female patients;their average age was (39.9± 11.7) years.We compared the quality indicators and evaluated the comprehensive quality of the patients before and after improvement.A total of 65 531 physical examination reports of subjects examined at the center between February and December 2017 were selected for effect tracking,including 39 230 (59.9％) men and 26 301(40.1％) women,aged (38.1±11.5).Results The on-time delivery rate of the health examination reports from rose from 51.4％ to 94.0％.The ratio of system leakage to sign for reports decreased from 14.5％ to 0.8％.The average time between the examination and when each report was handed over to for distribution decreased from 29.8 hours to 4.2 hours,and the average time between each report being distributed to the providers checking in dropped from 509.8 hours to 72.8 hours,while the average time for the preparation of each report for delivery decreased from 13.5 seconds to 3.1 seconds.The average time between delivery of a report and its being signed decreased from 4.3 seconds to 0.1 seconds.Before the improvement,the expected goals were not met.After improvement,the delivery rate of the health examination reports was 100.0％,the delivery intact rate of the group reports was 100.0％,and the satisfaction rate of the group reports was 99.4％.The comprehensive quality for the members was obviously higher after the improvement than before.After 11 months of tracking,the delivery accuracy rate of health examination report still failed to reach the target value of 100.0％,but all other indicators reached the target value,with good results.Conclusions Application of QCC not only improved the delivery the health checkup reports,but also promoted service quality after medical examinations and ended medical dispute caused by the loss of physical examination reports.

Objective:To explore the value of morphometric analysis program (MAP) in detecting focus of pediatric epilepsy related to focal cortical dysplasia (FCD) II.Methods:A retrospective analysis was performed; 42 epilepsy children with FCD II and postoperative Engel grading I in Department of Neurosurgery, He'nan Provincial People's Hospital from June 2020 to January 2023 were enrolled. Preoperative MRI data were analyzed by MAP. Difference in general data and focus detection rate by MRI and MAP were compared between the positive MAP group and negative MAP group, and consistency of MAP positive areas (true positive MAP and false positive MAP by postoperative CT) with interictal PET low metabolism positive areas was analyzed.Results:Of the 42 children, 28 had positive MAP and 14 had negative MAP in the epileptogenic focus. Gender was statistically different between positive MAP group and negative MAP group ( P<0.05). MAP had significantly better performance in focus detection compared with MRI (28/42 vs. 19/42, P<0.05). Significant difference was noted between consistency of true positive MAP area with interictal PET low metabolism positive areas (40/43) and that of false positive MAP area with interictal PET low metabolism positive areas (4/33, P<0.05). Conclusion:MAP can improve the focus detection rate of pediatric epilepsy related to FCD II effectively, and PET contributes to rule out false positive results.

Objective:To explore the mechanism of circular permuted tumor necrosis factor-related apoptosis-inducing ligand (CPT) reversing the resistance to imatinib in chronic myeloid leukemia (CML) cells.Methods:Five patients with CML in the Affiliated Hospital of Inner Mongolia Medical University from 2016 to 2020 were selected, and heparinized bone marrow blood samples were collected at the first diagnosis and imatinib resistance phase, and mononuclear cells were isolated. The mononuclear cells collected at the first diagnosis were named A1-E1, and the mononuclear cells collected after imatinib resistance were named A2-E2. Human CML wild-type K562 cell line (K562-W) was given gradually increasing small doses of low-concentration imatinib to obtain imatinib-resistant K562 cells (K562-R). K562-R cells were cultured with 20 μg/L CPT and these cells were set as CPT-K562-R group. The CCK-8 method was used to detect the half inhibitory concentration ( IC50) of cells for imatinib. K562-W and K562-R cells were used to establish CML xenografts nude mice models, then the nude mice were divided into K562-W, K562-R and CPT-K562-R xenograft groups. Imatinib was perfused orally in all three groups, and CPT was injected subcutaneously in the CPT-K562-R group at the same time. The tumor volume of the three groups of nude mice before and 4 weeks after treatment with imatinib, and the survival time of the three groups of nude mice were compared. Western blot was used to detect the changes of tyrosine protein kinase receptor B4 (EphB4) and myeloid cell leukemia protein 1 (Mcl-1) protein levels in bone marrow mononuclear cells, K562 cell line and transplanted tumor tissues of CML patients. Results:The expressions of EphB4 protein in A2-E2 cells of 5 patients with CML were higher than those in A1-E1 cells (all P < 0.01). The IC50 of K562-W, K562-R and CPT-K562-R cells for imatinib were (0.160±0.015) mg/L, (5.450±0.460) mg/L, (0.300±0.035) mg/L, and the difference was statistically significant ( F = 390.65, P < 0.01). In cells of K562-W group, EphB4 and Mcl-1 proteins were expressed at low levels (0.54±0.02 and 0.70±0.08); in cells of K562-R group, the expressions of EphB4 and Mcl-1 proteins were enhanced (3.04±0.11 and 2.88±0.04); in cells of CPT-K562-R group, the expressions of EphB4 and Mcl-1 proteins decreased (0.57±0.03 and 0.38±0.04). Before imatinib treatment, there was no statistically significant difference in the tumor volumes of nude mice among the K562-W, K562-R and CPT-K562-R xenograft groups ( F = 0.39, P = 0.68), suggesting the transplanted tumors formed in nude mice were balanced; after imatinib treatment, the difference in the tumor volumes among the three groups were statistically significant ( F = 26.16, P < 0.01). The survival time of nude mice in the K562-W, K562-R and CPT-K562-R xenograft groups was (18.5±3.3) d, (10.0±2.4) d and (17.5±1.6) d, and the difference was statistically significant ( F = 20.45, P < 0.01). In K562-W xenograft group, both EphB4 and Mcl-1 proteins were expressed at low levels (0.55±0.06 and 0.67±0.06); in K562-R xenograft group, the expressions of EphB4 and Mcl-1 proteins were enhanced (1.95±0.08 and 6.21±0.53); the expressions of EphB4 and Mcl-1 in CPT-K562-R xenograft group decreased (0.59±0.04 and 0.37±0.04) and were close to their expressions in K562-W xenograft group. Conclusion:CPT may enhance the sensitivity of CML to imatinib by inhibiting the expressions of EphB4 and Mcl-1, and this may be a targeted pathway for imatinib therapy.
