Hyperglycemia is considered to be a predictor of death, poor functional outcome, symptomatic intracerebral hemorrhage, and increased infarct volume in patients with acute ischemic stroke. Many studies have used parameters such as standard deviation, coefficient of variation, blood glucose level, stress hyperglycemia ratio, and glucose/glycated hemoglobin ratio to express hyperglycemia, and then study the relationship between hyperglycemia and stroke outcome. In patients with stroke receiving intravenous thrombolysis, hyperglycemia is closely associated with symptomatic intracerebral hemorrhage, poor neurological outcome, and lower vascular recanalization rate. In patients with stroke undergoing endovascular mechanical thrombectomy, hyperglycemia is closely associated with poor long-term outcome, increased mortality, and increased infarct volume. However, whether hyperglycemia will affect the effect of reperfusion therapy in acute ischemic stroke remains controversial. The possible mechanisms of hyperglycemia leading to poor outcomes after reperfusion therapy in patients with ischemic stroke include inhibition of vasodilation, reduction of plasma fibrinolytic activity, destruction of the blood-brain barrier, promotion of oxidative stress, and reduction of ischemic penumbra volume. Studies have shown that for stroke patients with hyperglycemia, intensive blood glucose control does not bring significant benefits. Therefore, the blood glucose control program of patients with acute ischemic stroke and hyperglycemia needs further study and discussion.

To investigate the level of serum IL-10 in allergic rhinitis patients and the correlation between IL-10 and serum total IgE (TIgE). 50 allergic rhinitis patients and 30 normal subjects were involved in the study. The levels of serum IL-10 and TIgE were measured by enzyme-linked immunosorbent assay (ELISA), and the correlation between serum IL-10 and TIgE was analyzed. In the allergic rhinitis group, the levels of serum IL-10 and TIgE were 8.34 +/- 2.48 pg/mL and 142.6 +/- 28.2 KU(A)/L. In the normal control group, they were 12.86 +/- 2.88 pg/mL and 47.2 +/- 12.2 KU(A). There were significant differences between the two groups (P < 0.01); and the level of serum TIgE in the patients was negatively correlated with that of IL-10 (r = -0.46, P = 0.02). The level of serum IL-10 was significantly decreased in allergic rhinitis patients, which was beneficial to the synthesization of IgE. IL-10 plays an important role in the episode of allergic rhinitis.

Objective To study the prognosis value of the expression of vascular endothelial growth factor and it's acceptor(VEGF,Flk-1) and microvessel density(MVD) gene proteins in the breast carcinoma and paracarcinoma tissue.Methods Immunohistochemical technique was adopted to detect the protein expression of VEGF,Flk-1 and MVD in 76 cases of breast carcinoma and 10 cases paracarcinoma tissue.Results (1)The positive expression of VEGF,Flk-1 were 59.3% and 61.3% in the carcinoma group,which were higher than in the paracarcinoma tissue(P

Objective To investigate the accuracy of computer-assisted interpretation(CAI)in the diagnosis of pediatric critical arrhythmia,and to establish Logistic regression model to evaluate the main risk factors of CAI error.Methods 1147 cases of arrhythmia patients were divided into heart disease(HD)and nonheart disease group(NHD).Candidate risk factors were chosen,from which the vailables statistically significant were entered for logistic regression analysis.Results CAI error rate of HD group and NHD group were 24.9%and 11.4%,showing a significant difference(P＜0.05).Age,underlying diseases,the number of CAI diagnosis entries were the risk factors.Conclusion CAI error pattern was different among HD group and the NHD group.Higher awareness for CAI error risk factors and CAI technology improvement are critical for a lower CAI error rate.

Objective To discuss the clinical treatment of unstable dislocation of the sternoclavicular joint with clavicle hook plates. Methods From April 2005 to October 2007, 19 cases of unstable dislo-cation of stemoclavicular joint were treated with open reduction and internal fixation by clavicle hook plates. There were 17 cases of Grade type Ⅲ and 2 cases of Grade type Ⅱ. After open reduction and internal fixation, all patients received arthroplasty and repair of eostoclavicular and sternoclavicular ligaments. Results None had intraoperative injury to nerves and blood vessels. Follow-ups from 6 to 24 (mean, 8) months showed 16 excellent cases, 2 good cases and 1 fair case by Roekwood criteria, the good to excellent rate being 94.7%. The healing duration lasted 3 to 6 (averaging 4) weeks. No infection, sliding or loosening of internal fixation, nonunion or re-dislocation was found postoperatively. Conclusion The clavicle hook plate is an effective and advanced surgical treatment of sternoclavieular joint injuries, because its easy and mini-invasive operation can provide sturdy fixation and lead to good functional recovery.

Objective: To explore how the Chinese- English Bilinguals represent knowledge of the second language. Methods: The inter- language priming effects were investigated in two priming- category judgement tasks based individual- ly on the semantic (ExperimentⅠand ExperimentⅡ) and phonological information (ExperimentⅢ and ExperimentⅣ). Re- sults: In experimentⅠand ExperimentⅡ, no matter what the relation between the English targets and the English primes was semantic association or homophones and similar phones, the significant priming effects were obtained; However, In the experimentⅢ, when the relation between the targets and the primes was semantic association, no significant priming effect was found; In experimentⅣ, when the relation was homophones and similar phones, the significant priming effects were obtained. Conclusion: ①The second language knowledge of Chinese- English Bilinguals was represented in the semantic and phonological characters; ②The conceptual representation could be discreted with the lexical representation.

Objective To study the adverse effects of outdoor air pollution on children's respiratory system health in Anshan city. Methods 1951 children were randomly selected from three areas with different degree of air pollution in Anshan city. The parents of the children were asked to answer a questionnaire about their children's respiratory health and home environment. The data of health were collected included persistent cough, persistent phlegm, asthma, current asthma, wheeze, and wheeze symptom. Results The prevalence rates of persistent cough, persistent phlegm, asthma, current asthma, wheeze and wheeze symptom were 9.48%, 4.82%, 1.33%, 0.92%, 6.30% and 4.97% respectively. Outdoor air pollution was a risk factor for persistent cough and persistent phlegm. The respiratory symptoms increased as the house became near to the main traffic lines. Combined effect of susceptible factor and outdoor air pollution was obvious, the prevalence rates of respiratory diseases were higher in the susceptible children who were influenced by the other risk factors compared with those who were not influenced by the same factors. Conclusion Outdoor air pollution is an important factor which will damage children's respiratory system in Anshan city.
