Objective:To investigate the effect of pioglitazone on white matter injury after cerebral ischemia-reperfusion in mice and its mechanism.Methods:Forty-two young male C57BL/6J mice were randomly divided into sham operation group, model group, and pioglitazone group ( n=14 in each group). The model of cerebral ischemia-reperfusion was induced by transient middle cerebral artery occlusion with suture-occluded method. On the 3 rd and 7 th day after the establishment of the model, the neural function was assessed by the adhesive removal test. The mice were killed on the 7 th day after the establishment of the model. HE staining was used to detect the extent of cerebral infarction. Immunofluorescence staining and Western blot analysis were used to detect the degree of white matter damage and the changes of microglia phenotype. Results:On the 7 th day after cerebral ischemia-reperfusion, the adhesive removal time in the PGZ group was significantly shortened compared with the model group ( P<0.05), the percentage of cerebral infarction volume was significantly reduced ( P<0.05), the ratio of MBP/NF200 fluorescence intensity in the cortical and striatal areas was significantly increased (all P<0.05), and the number of CD16 +/Iba1 + microglia was significantly decreased ( P<0.01), while the number of CD206 +/Iba1 + microglia tended to increase, but there was no statistical difference. Conclusion:Pioglitazone may reduce the degree of white matter injury and nerve function damage in mice with cerebral ischemia-reperfusion, and its mechanism may be associated with regulating the transformation of microglia from M1 type to M2 type.

Objective: To study the effects of sex, age, length of service, type of work and annual effective radiation dose on nucleoplasmic bridge (NPB) in the peripheral blood lymphocytes of radiation workers. Methods: The peripheral blood samples of 100 radiation workers in Henan province were collected and the NPB in peripheral blood lymphocytes were measured by CBMN assay. The frequencies of NPB formation and NPB-containing cells were calculated, and the effects of various factors on NPB incidence were analyzed statistically. Results: The NPB frequency in radiation workers was higher than that in healthy people (Z=-8.123, P<0.01). Except for sex, the factors of age, length of service, type of work and annual effective dose had significant influences on NPB (χ²= 7.202-45.571, P<0.05). Conclusions NPB reflects the effect of low-dose long-term chronic irradiation on the occupational radiation workers.

Objective:To investigate the effects of hyperbaric oxygen (HBO) combined with selegiline on motor function, serum microRNA-124 (miR-124), insulin-like growth factor-1 (IGF-1) in patients with Parkinson′s disease (PD).Methods:A total of 120 PD patients, admitted in the Department of Neurology of Jining No.1 People′s Hospital from the March of 2017 to the March of 2019, were selected and divided into control group and HBO group according to the random number table method with each group consisting of 60 patients. The patients in the control group received levodopa and selegiline treatment, while the patients of HBO group were treated with HBO combined with the same medication of the control group. After three courses of treatment, clinical symptoms of the two groups were observed; motor function was assessed by the unified Parkinson′s disease rating scale (UPDRS); non-motor function was assessed by the PD non-motor symptom questionnaire (NMSQuest) and the Parkinson′s disease sleep scale (PDSS); the levels of serum oxidative stress index, inflammatory factor, IGF-1 and miR-124 before and after treatment were compared.Results:After 30 d treatment, the incidences of mental disorders, sensory disturbances, autonomic nervous dysfunction and sleep disorders of the two groups were significantly lower than those before treatment, and those of HBO group after treatment were significantly lower than those of the control group ( P<0.01). The UPDRS II and UPDRS III scores of both groups after treatment were significantly lower than those before treatment ( P<0.05). The UPDRS II and UPDRS III scores of the HBO group after treatment were significantly lower than those of the control group ( P<0.05 or P<0.01).

Objective To discuss the correlation between family history of malignant neoplasms (MN-FH) and the clinicopathological features of patients with non-small cell lung cancer (NSCLC). Methods The clinicopathological data of 326 patients with NSCLC in Yangzhou University Affiliated Hospital from June 2016 to June 2018 were analyzed retrospectively. The patients were divided into two groups based on with or without MN-FH, and the clinicopathological features of the two groups were analyzed by χ 2 test. Results Of the 326 patients with NSCLC, 41 (12.6％) were in the MN-FH group and 285 (87.4％) in the MN-FH group. There were no significant differences in sex, age, smoking, location of tumors and histological classification between patients with or without MN-FH (χ 2 values were 0.031, 0.769, 0.546, 0.117, and 0.945, all P > 0.05), but in patients with MN-FH, the proportion of tumor diameter < 5 cm [65.9％ (27/41) vs. 42.5％(121/285), χ 2 = 14.173, P < 0.05], undifferentiation and low differentiation [70.7％ (29/41) vs. 53.7％(153/285), χ 2 = 4.224, P < 0.05], TNM stage Ⅲ+Ⅳ [65.9％ (27/41) vs. 46.7％ (133/285), χ 2 = 5.280, P <0.05], lymph node metastasis [78.0％ (32/41) vs. 60.0％ (171/285), χ 2 = 4.970, P < 0.05], distant metastasis [75.6％ (31/41) vs. 53.3％ (152/285), χ 2 = 7.224, P < 0.05], high degree of malignancy [70.7％ (29/41) vs. 51.6％ (147/285), χ 2 = 5.293, P < 0.05] and combination of other tumors [29.3％ (12/41) vs. 7.7％ (22/285),χ 2 = 17.817, P < 0.05] were significantly higher than those in patients without MN-FH. Conclusions NSCLC patients with MN-FH have a higher degree of malignancy. For people with MN-FH, physical examination is very important.

Objective To study the effect of recombinant human platelet activating factor acetylhydrolase (rPAF-AH) on candidate plasticity-related gene 15 (CPG15) expression in focal cerebral ischemia rats.Methods Forty-five SD rats were randomly divided into sham operation group,saline group and rPAF-AH group (15 in each group).A middle cerebral artery occlusion model of rats was established for the latter two groups.Each group was divided into 2 d group,7 d group,14 d group.Five rats in each of 2 d group,7 d group,14 d group were used in experiment.The total protein was extracted from coronary sections using homogenate.CPG15 protein expression was detected by Western blot.Results The CPG15 protein expression level was significantly higher in saline group and rPAF-AH group than in sham operation group on days 2,7,14 and reached its peak on day 7,and in rPAF-AH group than in saline group on day 7 (1.48±0.04 vs 1.12±0.05,P＜0.01).Conclusion PAF-AH plays a positive role in neuroplasticity of cerebral ischemia by upregulating the CPG-15 expression in focal cerebral ischemia rats.

Objective To observe the dynamic changes of myocardial structure and dysfunction during post-resuscitation period in order to establish a rat mode of post-resuscitation myocardial dysfunction after cardiac arrest resulted from electric stimulation-induced ventricular fibrillation (VF) and cardiopulmonary resuscitation (CPR).Methods A total of 40 male Sprague-Dawley (SD) rats were randomly (random number) assigned into post-resuscitation (PR) 4 h,PR 12 h,PR 24 h,PR 72 h and sham groups.VF was induced by an alternating electric current delivered to the right ventricular endocardium and untreated for 8 min.Biphasic waveform defibrillation was attempted and mechanical ventilation was synchronized after 6 min of CPR.Myocardial function was assessed with serum myocardial enzyme activity,echocardiography,mitochondrial respiratory function and histopathologic findings at different intervals.Results Thirty-two animals were successfully resuscitated with restoration of spontaneous circulation (ROSC) in 86％ (32/37) rats.Compared with sham group,severe systolic and diastolic heart failure were found at 4 h after ROSC and then gradually improved without significant difference (P ＞0.05) in ejection fraction at PR 72 h after ROSC was found,whereas thickened ventricular wall and increased myocardial performance index as well as interstitial proliferation were observed at 72 h after ROSC.Conclusions A rat model of post-resuscitation myocardial dysfunction after cardiac arrest resulted from electric stimulation-induced VF and CPR was successfully established.

Objective To investigate effective approach to decrease portal venous hypertension and high perfusion of portal vein caused by small-for-size (SFS) liver graft transplantation with the aim of improving hepatocellular microcirculation.Methods Rat models with SFS liver graft (n =62) were well estab lished and divided into SFS group and trans-portal intrabepatic portosystemic shunt (TPIPSS) group.Hemodynamic parameters,histopathologically morphologic changes,postoperative complications,accumulated survival rate were recorded and analyzed.Venous filling time after liver reperfusion,hemodynamic parameters were evaluated using t test and Kruskal-Wallis test.Kaplan-Meier method was performed for survival analysis.Results Venous filling time after liver reperfusion was remarkably prolonged with the application of multihole cone-shaped tubes.Compared with SFS group,the filling time was 4-second longer in TPIPSS.At each endpoints of reperfusion within 90 mins,the portal vein pressures were lowered in the TPIPSS group than those of SFS group.Liver grafts were present with more regular structures in TPIPSS group,with no sign of hepatic sinusoid congestion or irregular clearance extension.In the aspect of postoperative complications,all the rat receivers showed ascites in the SFS group.Nevertheless,there was no ascites observed in TPIPSS rats,and 50％ rats (5/10) experienced clinical manifestations of hepatic encephalopathy.Persistent fever over 7 days was showed in 10％ rats (1/10) of SFS group and 40％ rats (4/10) of TPIPSS group,respectively.The mean survival was superior in TPIPSS group (37.2 ± 23.5) d than SFS group (17.7 ± 13.5) d,P ＜ 0.05.Conclusion TPIPSS could be a safe and feasible approach to improve portal venous hypertension caused by SFS liver graft and hepatocellular reperfusion.
