Complications that follow ischemic stroke are common,frequency ranging from 28% to 95%.It may either directly lead to death or prevent optimal recovery.54% of deaths after ischemic stroke are attributed to medical complications.Most complications occur during the first week,and stroke severity is the most important risk factor.The common serious medical complications are chest or urinary tract infection,deep venous thrombosis,pulmonary embolism,cardiac events,gastrointestinal bleeding,hyperglycemia,pressure sores.Falls,shoulder pain and depression are also common complications.Most of medical complications are preventable or treatable to some extent if recognized,so preventive strategies and appropriate treatment should be employed as early as possible.Prevention,early recognition,and management complications could improve short-term and long-term prognoses after ischemic stroke.

The principle and structure of the near-IR laser spectrum noninvasive blood glucose detection system are introduced in the paper. To meet the detection demand of the little DC current signal in the system,the current measure methods are analyzed. The hardware and software structure are discussed in the end.

Brain tumor stem cells (BTSCs) play a key role in tumorigenesis and tumor development.There are a group of special markers in the surface of brain tumor stem cells,which can sorts stem cells,precursor cells and cancer stem cells.In recent years,the studies of CD133,Nestin,high-mobility group A1,A2B5 have made some breakthroughs.

Objective To analyze the CT features of hepatic artery and morphology changes of the liver in patients with cavernous transformation of the portal vein (CTPV). Methods Thirteen patients of CTPV without malignant hepatic tumor or other diseases being able to cause changes of hepatic artery such as cirrhosis and hepatophyma were collected. CT data was analyzed, and the arterial and morphology changes of the liver were observed. Results Left and (or) right hepatic arteries were found dilated in 10 patients (76.92%), and unusual flake like enhancement was found in artery phase in 3 patients (23.08%). Atrophy-hypertrophy complex (AHC) could be found only in 1 patient (7.69%). Conclusion Dilatation of hepatic artery manifests more hepatic artery blood supply, while obvious AHC is hardly found in CTPV.

Objective To understand head nurse's leadership behavior and analyze the influence of it on nurse's involvement and self-efficacy.Methods General information questionnaire was taken,and the data of 280 nurses to head nurse's leadership behavior,involvement and self-efficacy were investigated.Results There were differences in nurse's involvement and self-efficacy between head nurse's transformation and transaction leadership behavior (F=4.39,2.37,2.94,2.17,P ＜0.05).The transformation leadership behavior dimensions were positive correlation with nurse's involvement and self-efficacy,P＜0.05.Conclusion Head nurse should fully play a positive role of transformation leadership behavior,in order to promote involvement and improve self-efficacy.

Objective:To analyze the lymphocyte activation from patients with different activities of multiple sclerosis (MS) and its clinical signifiance. Methods: The positive percentage of CD69 and HLA-DR were determined on peripheral blood (PB) or cerebrospinal fluid (CSF) lymphocytes by flow cytometry from 28 patients with relapsing-remitting MS (relapses n - 20, remission n = 8) , 12 patients with relapse MS and 11 patients with relapse MS after glucocorticoid treatment. ResultS:The percentage of HLA-DR+ and CD3+ /HLA-DR+ on PB lymphocytes in relapses MS group were higher than in remission MS group and controls. The percentage of CD3+ /HLA-DR+ on PB lymphocytes in remission MS group were higher than in controls. The percentage of CD69+ , HLA-DR+ and CD3+ /HLA-DR+ were higher in CSF than in PB of patients with relapse MS. There was no significant correlation between the levels of CD69+ , HLA-DR+ , CDS+ /HLA-DR+ and the time of onset of clinical relapse, duration, clinical disability scale score(EDSS) . In patients with relapse MS, there was significant positive correlation between CD69+ expression on CSF lymphocytes and blood brain barrier damage, intravenous glucocorticoid treatment caused a significant changes in the positive percentage of HLA-DR on PB lymphocytes. Conclusion:The findings support that lymphocyte activation involvement of MS pathogenesis. Lymphocyte activation may be as a marker of disease activity in MS.

Objective To observe the change of neuron-specific enolase (NSE) an d glial fibrillary acidic protein (GFAP) in neonatal rats' cerebral cortex with hypoxic-ischemic brain damage (HIBD). Methods The 7 day- old SD rats were subjected to the ligation of right carotid artery, then were pu t into a hypoxic box to establish a HIBD model. The immunohistochemical method w as used to detect the expression of NSE and GFAP in rats' cerebral cortex. Results ① The NSE decreased in damaged cerebral cortex in HIBD 24 h group, after 7 days it gradually increased but was still lower than that of the controls. ② The expression of GFAP was limited and scarce in control and it did not change in HIBD 24 h group, while in HIBD 7 d group GFAP expression was increased and spread widely in the damaged cerebral cortex. Conclu sion ① The NSE decreases in damaged cerebral cortex in early stage of neonatal rat HIBD, suggesting that NSE is a specific marker for neuron damage . ② The GFAP increases in damaged cerebral cortex in the recovery stage of neon atal rat HIBD, suggesting that GFAP participates the repair of lesion region.

Objective:In 2003,a survey of the manpower of pediatric dentists was made in China in order to provide basis for database. Methods:Questionnaires were distributed to dentists presenced the 5th conference of pediatric dentistry in China,and 139 available answers were analysis. Results:In those 139 pediatric dentists, with a mean age of 38.2?8.7,females were significantly more than males, and 89.9% dentists had bachelor, master or doctor degree. Significant relations were found between self-estimate ability of dentists and their length of work, degree, character of clinic.Conclusion:To date, the team of pediatric dentists begins to take shape, the structure of age and education are rational, but the number of them is insufficient and it is necessary to improve the basic and continuing education.
