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.

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

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.

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

Objective To investigate the safety and feasibility of laparoscopic ELAPE for elderly patients with low advanced rectal cancer.Methods Totally 48 cases patients with low advanced rectal cancer surgery aged over 65 years old were analyzed retrospectively,who come from Beijing Hospital between Jan 2012 and Jan 2015.A total of 26 cases underwent Laparoscopic extralevator abdominoperineal excision (L-ELAPE) and 22 cases underwent Laparoscopic abdominoperineal excision(L-APE).Clinical data including general data,operation time,intraoperative blood loss,complications,pathological data,postoperative in hospitalization were retrospectively analyzed in patients.Results The mean operation time between L-ELAPE and APE group was (312±46)min vs.(245±62)min,mean intraoperative blood loss was(170±74)ml vs.(250± 109)ml,Operative complications was 26.9％ vs.27.3％,harvested lymph node was (16.0 ± 5.8)cm vs.(15.0±7.2)cm,intraoperative bowel perforation(IOP)rate was 0％ vs.18.2％,CRM involvement was 3.8 ％ vs.13.6 ％,mean postoperative hospital stay (days) was (13.1 ± 4.6) d vs.(13.7 ± 6.1) d.The mean operating time of L-ELAPE group was longer and mean intraoperative blood loss was much less than APE group,IOP rate and circumferential resection margin(CRM)involvement were higher in APE group(P＜0.05).Conclusions L-ELAPE is a safe and feasibility alternative approach for elder patients with rectal cancer.It is related with less intraoperative blood loss,IOP rate,CRM involvement and longer operating time contrast with L-APE.

Objective To investigate the status quo of psychological capital and compassion fatigue in operating room nurses and to analyze the correlation between them.Method One hundred and ninety nurses from an operating room of four First-Class Grade A general hospitals in Beijing were engaged in the investigation by psychological capital questionnaire and compassion fatigue scales.Results The total score on psychological capital was (78.60±8.72) and the total score on compassion fatigue was (111.53 ±9.88).The mental capital was negatively correlated with compassion fatigue (P ＜0.05).Conclusions The psychological capital of the nurses in the operating room is at the middle level and the sympathetic fatigue is at a high level.The higher the psychological capital,the lower the sympathetic fatigue.Nursing administrators can improve the psychological capital of the nurses in the operating room to reduce their sympathy and fatigue so as to improve the level of mental health of nurses in the operating room.

For patients with poor liver function as a result of the final stage of liver disease,liver transplantation is the best way to prevent them from death.Recently,liver transplantation in China get a rapid development,however,patients who need liver transplantation are much more than livers that can be transplanted,that is a bottleneck problem for liver transplantation,adoption of brain death must be a useful way to deal with this problem.More than a hundred countries have adopted brain death and their liver transplantation developed much better than China.Thus,we should pay more attention to brain death and corresponding legislation to promote the development of liver transplantation.

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.
