Objective To explore the impact of executive function intervention on the executive functioning of elderly patients with cerebral infarction,and to seek the best way to improve executive function in such patients.Methods Eighty elderly patients with cerebral infarction were randomly divided into an intervention group and a control group.A series of executive function interventions were administered to those in the intervention group with no intervention in the control group.The two groups were given the same conventional medication.The Behavioral Assessment of the Dysexecutive Syndrome (BADS) was taken before the intervention,then 3 months and 6 months after recruitment.Results In the intervention group the average score and the total standard score had increased significantly after 3 months except for the action program test and the modified six elements test.Both indicators were still significantly increased from the baseline afar 6 months except for the modified six elements test.The average score and the total standard score had increased significantly between 3 months and 6 months except on the key search test.Both the time determination test and the total standard score had statistically significant average differences.The control group showed no significant differences.After 3 months,the average scores and the total test standard scores in the intervention group were signifieantiy higher than those in control group except on the action program test.The rules conversion card test,the time determination test and the total standard score difference all showed statistically significant differences between the groups.After 6 months the intervention group's scores remained significantly higher than those of the control group except on the action program test.Conclusions Executive function interventions are effective in delaying the progress and improving the prognosis of executive dysfunction in elderly patients with cerebral infarction,and the therapy has persistent effects.

Objective　To analyze the advantages of intracrani al hematoma smash puncture (IHSP) in the treatment of cranial hemorrhage for the elderly. Methods　A total of 104 cases of cerebral hemorrhage a dmitted in the recent 3 years were collected and divided into 4 grou ps, i.e . group A, elderly with IHSP treatment (n=36), group B, elderly with regular medical treatment (n=33), group C, non-elderly with IHSP treatment (n= 21) and group D, non-elderly with routine therapy (n=14). The clinical and follow-up outcomes were studied and analyzed. Results　There w as significant difference in rehemorrhage rate after puncture between grou p A (0/36) and group C (2/21). Significant difference was found in early mortali ty rate in group A (16.67%) and group B (39.40%). The rate of activity of daily living (ADL) 1-2 was significantly higher in group A (58.62%) than group B (5.88 %)(P<0.005) and that of ADL 4-5 was obvious lower in group A (13.79%) than g roup B (47.06%)(P<0.025). Conclusion　Intracranial hematoma smash hemorrage is safe and efficient in the treatment of elderly cerebr al hemorrhage, especially in reducing the disability rate.

Objective To investigate the mechanisms of oxygen free radical/JNK signaling pathway on neuronal autophagy after subarachnoid hemorrhage(SAH) in rats.Methods 160 male Sprague-Dawley rats were randomly divided into four groups: sham group, SAH model group, low dose Edaravone group and high dose Edaravone group.The SAH model was established by autologous blood injection into cisterna magna twice, while the rats in the sham group were injected with isotonic saline(0.3mL/time).The high dose of edaravone group and low dose of edaravone group were given 5mg/kg or 10mg/kg of edaravone, respectively, once daily with tail intravenous injection after the models were established.The morphological changes of hippocampus neural cells were detected by light microscope.The malondialdehyde (MDA) level in brain tissue was determined with thiobarbituric acid.The changes of phosphorylated JNK and autophagic biomarkers (Beclin-1 and LC3-II)were detected by immunohistochemical method.The expressions of JNK mRNA,Beclin-1 mRNA and LC3 mRNA in hippocampus was detected by Real time-quantitative PCR.Results The necrotic nerve cells were seen in the hippocampus of SAH group in terms of nuclear dissolution, nuclear fragmentation or nuclear disappearance.Compared with Sham group, the level of MDA and the number of dead neurons, the expression of JNK mRNA, Beclin-1 mRNA and LC3-Ⅱ mRNA were increased in the SAH group (P<0.05).The survival rate of nerve cells in the SAH group was lower than that in the sham group.The immunoreactivity of phosphorylated JNK 、Beclin-1 and LC3-Ⅱ in the SAH group was enhanced than that in the sham group.However the damage of the morphological structure of nerve cells was relatively decreased in both doses groups.Compared with SAH group, the level of MDA and the expression of JNK mRNA in low dose Edaravone group and high dose Edaravone group were decreased.The expression of Beclin-1 mRNA and LC-3 mRNA was higher (P<0.05).Furthermore, the survival rates of nerve cells in both dosesgroups were higher than that in the SAH group (P<0.05).Meanwhile, the immunoreactivity of phosphorylated JNK in both doses groups was weakened than that in the SAH group.The mRNA expression of Beclin-1 and LC3-Ⅱ was increased(P<0.05).Conclusion Oxygen free radical played an important role in process of neuronloss by activating the JNK signaling pathway to regulate Beclin-1 and LC3-Ⅱ expression.

Objective:Evaluate the role of reactive oxygen species production and the differential expression of Rac2 and RhoGDI of neutrophils in pathogenesis of coronary heart disease.Methods:Reactive oxygen species production was measured by chemiluminescence method,the mRNA expression of Rac2 and RhoGDI was detected by quantitative RT-PCR.Results:The reactive oxygen species production by neutrophil is significantly increased in the coronary heart disease group,and the increase is related to the inflammatory cytokines in plasma.There is a significant increase of Rac2mRNA expression in coronary heart disease group than that of the control,while the expression of RhoGDImRNA in two groups are not significantly different.The ratio of Rac2mRNA to RhoGDImRNA is correlated to the production of reactive oxygen species of neutrophils.Conclusion:Netrophils are involved in the pathogenesis of coronary heart disease through their reactive oxygen species production,and the abnormal expression of Rac2 and RhoGDI is an important cause leading to the increased reactive oxygen species production.

[Objective]To evaluate the possibility and clinical value of total en bloc spondylectomy for the treatment of spinal tumors. [Method]Four cases of primary tumor of the thoracolumbar spine were treated with total en bloc spondylectomy TES through a single posterior approach performed in three cases(T10 solitary plasmacytoma,T8 hemangioma,and T12 hemangioma),and one case through a single stage anterior and posterior combined approach(L4 neuroblastoma with paraspinal mass).Improvements in osteotomy apparatus and surgical technique of TES were investigated.[Result]All patients attained significant clinical improvement after surgery without any severe complications.Patients were observed for 13 to 22 months.There was no local recurrence and distal metastasis by the last follow-up.[Conclusion]Total en bloc spondylectomy includes resection of the involved vertebra in two major blocs,rather than a piecemeal pattern.It is one of the most effective therapies for spinal tumors.Howerer,some components of TES remain to be further improved.

Objective: To investigate the protective effects and the mechanism of the preconditioning with hypertonic saline against warm hepatic ischemia-reperfusion (I-R) injury. Methods: Sixty patients who underwent partial liver resection were randomly assigned to 3 groups (n =20): group 1 without Pringle maneuver(NPR); group 2 with Pringle maneuver (PR), and group 3 with 7.5% hypertonic saline 4ml/kg preconditioning (HS) 5 minutes before Pringle maneuver for resection and in group 2 , 4ml/kg normal saline were given. Blood samples were obtained at 3, 15, and 30 minutes before and after liver resection, and 2, 24, and 48 hours following resection of the liver for polymorphonuclear leukocytes (PMN) count and serum alanine transminase levels test. In addition, small pieces of liver tissue were cut from remaining liver before resection and 30 minutes after resection to determine MPO concentrations. Results: Following partial liver resection via NPR, no changes in the concentration of circulating PMN and liver MPO concentrations were observed. But in the PR and HS group PMN counts significantly decreased and liver MPO concentrations significantly increased. Serum ALT levels increased in all groups significantly 24 and 48 hours after resection. All of these changes were most pronounced in the PR group and significantly reduced by hypertonic saline. Conclusion: Preconditioning with 7.5% hypertonic saline can protect liver from warm ischemia reperfusion injury and the possible mechanism was the inhibition of PMN accumulation in the liver.
