Intracranial aneurysm often result from congenital defects of regional cerebral artery wall and increased endovascular pressure.Its occurrence and development are associated with several risk factors including genetics,smoking,hypertension,cerebral atherosclerosis and vasculitis.With the application of gene chip technology for the past few years,the research of pathogenic genes associated with intracranial aneurysms was further deepened,and some susceptibility genes closely associated with the occurrence of intracranial aneurysms have been found,and this suggests that intracranial aneurysm may be a polygenic disease caused by the combined action of multiple genes.

Objective To study the protective effect on transient focal cerebral ischemic preconditioning against neuronal cell apoptosis again,and the relationship between bcl 2, bax and cerebral ischemic tolerance.Methods Middle cerebral artery occlusion (MCAO) was showed for 20 min by craniotomy and MCA was blocked 6 h after 3 d.Cerebral infarct volume and the change of histopathological in rats were observed,the status of neuronal cell apoptosis were observed by TUNEL mothod,the alteration of bcl 2 and bax protein expression were observed by immunohistochemical method.Results As compared with the false preconditioning group and ischemia group,the infarct volume in the ischemic group reduced significantly after preconditioning( P

Objective To investigate the protective role of transient focal ischemic precondition(PC) against permanent focal cerebral ischemia, to define the proper time dose for precondition, and to study the reaction of astroglia in cerebral ischemic tolerance. Methods Temporary middle cerebral artery occlusion(10 minutes, 20 minutes, 30 minutes) followed three day reperfusion before permanent middle cerebral artery occlusion(PMCAO) transcranially was used as precondition in Wistar rats. The protective role was evaluated by observing the neurological deficits, analyzing the infarct volume and studying changes of pathohistology. The reaction of astroglia was observed by using anti GFAP immunohistochemistry.Results Compared with the control group, 20 min ischemic precondition, which did not produce neuronal damage obviously, alleviated the neurological deficits and reduced the infarct volume significantly( P

Cardiovascular and cerebrovascular diseases is the most fatal diseases in the world.The prevention and treatment of cardiovascular and cerebrovascular diseases are both basic and clinical focus.Aspirin has been used as a prevention medicine in cardiovascular and cerebrovascular diseases for over a century, which is the longest one in history.Aspirin use is estimated at 100 billion tablets annually as an analgesic, antipyretic and antiplatelet drugs.However, there are still many new findings about aspirin, such as aspirin resistance and aspirin hydrolase.This paper reviews the current research advances and future directions of aspirin in cardiovascular and cerebravascwlar diseases, mainly focuses on aspirin resistance and personalized medication.

Objective To study the methods and effects by using thrombolytic catheter in interventional treatment for patients with acute lower limb arterial thrombosis or embolism. Methods One hundred and twelve patients suffered acute lower limb arterial thrombosis or embolism. There were 85 cases of acute lower limb arterial embolism induced by atrial fibrillation in coronary or rheumatic heart disease,other 27 cases of arterial thrombosis caused by different reasons. Interventional treatment by inlying thrombolytic catheter was applied and continuous perfusion was received locally in all patients. Results Complete recanalization was got in 77 cases (68.8%) of 112 cases. Partial re canalization was got in 23 cases (20.5%), and ischemia limbs were saved in spite of chronic limb ischemia(chronic spasmodic limb) occurring in the later follow-up. Nine cases (8.0%) were amputated as a result of irreversible limbs necrosis, 3 cases (2.7%) died from acute renal failure resulting from reperfusion injury or recurrent cerebral embolism.Conclusion Interventional treatment by inlying thrombolytic catheter is a safe and effective method with lower amputation rate for acute lower limb arterial thrombosis or embolism in patients.

The mechanism of bone marrow relapse in pediatric acute lymphoblastic leukemia has been deeply researched in recent years. The roles of hematopoietic stem cells, some gene abnormalities including IKZF1, JAK, CRLF2 and CREBBP, as well as mutation of genes influencing drug resistance have been confirmed to related with relapse of disease. The microRNAs, gene expression profile of patient, microenvironment of bone marrow including bone marrow fibrosis, mesenchymal stem cells and matrix metalloprotease, also play an important role in the process of leukemia recurrence. This article reviewed the details mentioned above.

Hydatid is a common pathogen found in human and animals,incidence of hepatic echinococcosis is high in the west China.In recent years,operation and chemotherapy are basic treatment.Faced with varieties of operational manner,a proper choice is very important.5 operational manners are compared in this article,furthermore,problems in the selection of operational manner is analysed.

Objective To investigate the factors affecting the recovery of immunological function after bilirubin decreasing interventional therapy in patients with obstructive jaundice.Methods 67 patients with malignant obstructive jaundice were investigated.The patients were randomly divided into the enteral nutrition (EN) group (n =34)and the parenteral nutrition (PN) group (n =33).TBIL,DBIL,TSP,ALB,PA,TF,CD3 +,CD4 +,CD8 +,CD4 +/CD8 + were determined before PTCD and at the 7th day after the procedure.Results Except for 20 patients,the levels of TBIL,DBIL,CD8 + significantly declined,and the levels of TSP,ALB,PA,TF,CD3+,CD4+,CD4+/CD8 + significantly increased in the 2 groups of patients.There was no significant difference in the recovery of liver function and immunological status between the PN and the EN groups.Conclusions The recovery of immunological function was significantly associated with reduction of serum bilirubin in patients with malignant obstructive jaundice.There was no relationship with the ways of nutrition support.

Objective To examine the relationship between social functioning and psychiatric symptoms,and the mediation effect of self-esteem and emotion between social functioning and psychiatric symptoms among schizophrenia patients of the convalescent stage.Methods The Personal and Social Performance Scale,Brief Psychiatric Rating Scale,Self-Esteem Scale,General Self-Efficacy Scale were used to investigate patients with schizophrenia of the convalescent stage of Chifeng.Results Social functioning for patients with schizophrenia of the convalescent stage could predict psychiatric symptoms directly.Self-esteem and self-efficacy could make a negative prediction for psychiatric symptoms.Self-esteem and self-efficacy played a mediating role between social functioning and psychiatric symptoms.Conclusions Mental health workers should pay close attention to the mediating roles of self-esteem and self-efficacy,and give comprehensive assessment for the patients and provide continuous individualized psychosocial interventions,and thereby to alleviate psychiatric symptoms.

Objective To investigate the effects of human interlukin-13 (hIL-13) on the expression of E- selectin and intercellular adhesion molecule-1(ICAM-1) on bovine aortic endothelial cells(BAECs) stimulated by tumor necrosis factor alpha(TNF-?), and to provide experimental basis for hIL-13 inducing immunity endure and relieving the repulsion reaction of xenograft. Methods BAECs were co-cultured with different concentrations of hIL-13 for 2 h and followed by co-cultured with 4 ng/ml TNF-? for 6 h or 18 h. The expressions of E-selectin and ICAM-1 on BAECs were detected by Cell-ELISA. The effect of hIL-13 on activity of BAECs was detected by MTT colorimetry.Results BAECs pretreateded with hIL-13 could inhibit the expression of E-selectin and ICAM-1 induced by TNF-?, and showed a does-dependent manner from 5 ng/ml to 20 ng/ml of hIL-13 (P
