ObjectiveTo investigate the executive functions of the frontal and temporal lobe epilepsy patients.MethodsFifty-five epilepsy patients (twenty-five frontal lobe epilepsy patients and thirty temporal lobe epilepsy patients) and fifty age,gender and education matched healthy controls were evaluated by means of Mini Mental State Examination ( MMSE ).Executive function was assessed using Stroop color words test and trail making test.ResultsMMSE total score of frontal and temporal lobe epilepsy patients were ( 26.02 ± 0.30) and (25.82 ± 0.67 ),respectively.There was significant abnormality between epilepsy patients and the controls (P ＜0.05).Compared with normal control group,FLP group and TLP group took longer time and their score was lower in stroop color words test (P＜0.05).There were significant difference between FLP and TLP on card B and C's reading time,correct number and strcop interference effects (P＜0.05).The epilepsy patients performed significantly worse than the controls in whole trail making test (P＜0.05).The scores indicate that the TLE group outperformed the FLE group on all analysis values (P ＜ 0.05 ).ConclusionThe frontal and temporal lobe epilepsy patients have executive function deficit.The FLE group has prominent deficits in executive functioning.

Objective To study the role of PI3K-Akt-GSK-3β signaling in the apoptosis of renal tubular cells after ischemia-reperfusion injury and the protective mechanism of recombinant human erythropoietin(rHuEPO). Methods The human kidney tubular epithelial cells(HK-2)were cultured in vitro in different conditions as control group with serum, ischemia-reperfusion(IR)group, LY294002 group with LY294002(AKT inhibitor)10 μmol/L 30 minutes before IR treatment, LiCl group with LiCl(GSK-33 inhibitor)20 μtmol/L 30 minutes before IR treatment, rHuKPO group with EPO 20 U/ml 30 minutes before IR treatment, rHuEPO + LY294002 group with EPO 20 U/ml and in the presence of LY294002(10 μmol/L)30 minutes before IR treatment, rHuEPO +LiCl group with EPO 20 U/ml and in the presence of LiCl(20 μmol/L)30 minutes before IR treatment. Akt, GSK-33 and caspase-3 activation were measured by Western blotting. The apoptotic ratio of HK-2 cells was measured by flow cytometry. Cell viability was detected by MTT. Results In comparison with the control group, the apoptotic ratio raised up to 15.20%±1.43%, the expression of Akt activity decreased, GSK-33 activity and caspase-3 activity markedly elevated in IR group(P<0.05). LY294002 group up-regulated the apoptotic ratio(18.20%±2.06%), decreased the expression of Akt activity, increased GSK-33 activity and caspase-3 activity, however, LiCl group down-regulated the apoptotic ratio(12.30%±0.85%), increased the expression of Akt activity, decreased GSK-33 activity and caspase-3 activity compared with IR group(P<0.05). rHuEPO group remarkably decreased the apoptotic ratio(11.10%±1.62%), increased the expression of Akt activity, decreased GSK-33 activity and caspase-3 activity compared with IR group(P<0.05). rHuEPO+LY294002 group elevated the apoptotic ratio(13.40%±1.94%), decreased the expression of Akt activity, increased GSK-33 activity and caspase-3 activity, meanwhile, rHuEPO +LiCl group down-regulated the apoptotic ratio(7.50%±1.31%), increased the expression of Akt activity, decreased GSK-33 activity and caspase-3 activity compared with rHuEPO group(P<0.05). Conclusions PI3K-Akt-GSK-3β signaling pathway is involved in HK-2 cells apoptosis induced by ischemia-reperfusion injury and rHuEPO may be used as a new therapy.

Objective To investigate the recognition of nurses and patients on chosing daily caregivers and analyze the influencing factors. Method Totally 1,119 nurses and 1,134 patients from five first-class and two second-class hospitals in Zhuhai participated in the survey using self-designed questionnaires from April to June in 2014. Results There were significant differences between nurses and patients in all life nursing projects (P<0.001) except making beds for patients. The top three factors influencing the nurses′recognition were shortage of nursing staff and time, less presence of professional values and feeling no respects. The top three factors influencing the patients′recognition included tending to be nursed by family members, worries about medical expenses, and nurses′being too busy on treatment. Conclusion The different recognitions of nurses and patients on daily caregivers are influenced by multiple factors. Therefore , nursing managers should take some effective strategies to change the concepts of nurses and patients so as to improve quality of nursing service.

Objective The preventive effect of epigallocatechin gallate(EGCG)on hyperglycemia-induced hemorrhagic transformation(HT)was analyzed,and the underlying mechanisms were further explored.Methods Male SD rats were randomly divided into sham operation group(Sham,n = 20),model group(n = 27),hyperglycemia model group(HG,n = 43),and EGCG group(n = 43).In the model group,only the electrocoagulation cerebral ischemia model was established,and the HG group and the EGCG group were used to establish the HT model with acute hyperglycemia combined with electrocoagulation cerebral ischemia model.In addition,EGCG was adminis-tered by gavage for 5 days before cerebral ischemia at a dose of 50 mg/kg/d.Further studies confirmed the relevant targets by using network pharmacology to predict the potential targets and pathways of EGCG in the occurrence of HT.Results Compared with the model group,the mortality rate of the rats in the HG group was significantly increased[21.2%(6/27)vs.51.2%(22/43),P＜0.05].The mortality of rats in the EGCG group was significantly lower than that in the HG group[30.20%(13/43)vs.51.2%(22/43),P＜0.05].Second,mNSS,Longa score and infarct volume in the EGCG group were significantly lower than those in the HG group(P＜0.05).The incidence of HT in the HG group was higher than that in the model group(59.3%vs.90.7%).EGCG significantly reduced the incidence of hyperglycemia-induced HT to 69.8%.Compared with the HG group,EGCG decreased the hemoglobin content from(53.42±5.11)mg/dL to(37.04±2.39)mg/dL respectively(P＜0.05).Network pharmacology revealed that Nrf2-Keap1-mediated neuroinflammation may be associated with hyperglycemia-induced HT.The expression of Nrf2 and Keap1 was significantly decreased and the expression of TLR4 and phosphorylation of NF-κB was significantly increased in the HG group,but EGCG reversed this process.Conclusion EGCG pretreatment prevents the occurrence of HT,which may be related to the neuroprotection mediated by activation of the Nrf2-Keap1 signaling pathway.
