ObjectiveTo investigate the relationship between microalbuminuria (MAU) and short-term outcome in patients with acute ischemic stroke.MethodsThe consecutive patients with acute ischemic stroke admitted to hospital were enrolled prospectively.The first urine specimen was taken on the following morning after admission for detecting urine albumin/creatinine ratio (UACR).UACR 30-300 mg/g was defined as MAU positive.Stroke severity was evaluated with the National Institutes of Health Stroke Scale (NIHSS) at admission and the modified Rankin Scale (mRS) was used to evaluate functional outcome at discharge, and good outcome was defined as mRS score of 0 to 2.ResultsA total of 244 patients with acute ischemic stroke were enrolled, including MAU positive in 53 patients (27.12%), and poor outcome in 67 patients (27.50%).Univariate analysis showed that age, baseline NIHSS score, systolic blood pressure, fasting blood glucose, globulin, D-dimer, white blood cell count, neutrophils, and the proportions of ischemic heart disease in patients of the MAU positive group were significantly higher than those of the MAU negative group (all P<0.05).Multivariate logistic regression analysis showed that MAU (odds ratio [OR] 1.520, 95% confidence interval [CI] 1.151-1.794;P=0.031), baseline NIHSS score (OR 1.570,95% CI 1.357-1.808;P<0.001) were the independent risk factors for short-term poor outcome in patients with acute ischemic stroke.ConclusionsThe incidence of MAU is high in patients with acute ischemic stroke.MAU positive can be used as one of the independent predictors of short-term poor outcome in patients with acute ischemic stroke.

Objective:To analyze the polymorphism in human cDNA sequence of prothymosin-?(ProT?)by sequencing analysis.Methods:The cDNA of human ProT? was amplified from cells of peripheral blood and cord blood by RT-PCR.The product of RT-PCR was purified and linked with vector pMD18-T.After cloning and sequencing,the sequence of ProT? cDNA was compared with the standard sequence to analyze the polymorphism in the ProT? cDNA sequence.Results:The cloned ProT? cDNA sequence was different from that of the standard.We found 2 kinds of variations:(1)The nucleotide in 107 position was varied and the nucleotides in 110-121 and 191-205 positions were deleted;(2)The nucleotide in 306 position was deleted,mainly in the 60-80 years old group.Conclusion:We have identified 2 kinds of variations in human ProT? cDNA,but the first 28 amino acid in the N-terminal of cDNA of human ProT? are not involved therefore the variations do not affect the function of human ProT?.

Objective To observe microRNA-124 expression in the serum of patient with intracerebral hemorrhage and explore the relationship between the expression and associated clinical factors. Methods Thirty serum specimen were collected among patients with intracerebral hemorrhage, who were checked up at the same time in the hospital. Relative expression of microRNA-124 in serum was detected. The variation of MicroRNA-124 expression between the two groups and clinical data of patients with intracerebral hemorrhage were analyzed. The relationship between microRNA-124 and clinical factors related to intracerebral hemorrhage was explored. Results Compared with healthy people, microRNA- 124 expression in serum increased among patients with intracerebral hemorrhage (P<0.05) . The expression is related to the bleeding volume and onset time (P<0.05) . Meanwhile, no obvious correlation is established between serum microRNA-124 expression and other factors in patients with intracerebral hemorrhage, such as gender, bleeding area, with or without surgical treatment (including minimally invasive and craniotomy), a history of high blood pressure, fasting venous blood glucose levels (FPG), and cerebrovascular disease history (P>0.05) . Conclusion The serum microRNA-124 expression in patients with intracerebral hemorrhage is higher than that in healthy people. Bleeding volume positively increases expression. A higher expression is seen within one week at the onset of intracerebral hemorrhage compared to that one week after.

This study is to investigate the effect of total flavonoids of Uygur medicine bugloss (BTF) on rats with myocardial ischemia/reperfusion injury, and to explore the mechanisms by which it acts. Left anterior descending (LAD) coronary artery in rats was occluded for 30 min followed by 4 h reperfusion. Meanwhile, BTF dissolved in saline was administered intraperitoneally at dosage of 10, 30 and 50 mg x kg(-1). Electrocardiograph, infarction index, serum myocardial enzymes and heart function were determined to evaluate the effect of BTF. Some other observations were carried out to explore whether inhibiting inflammation and apoptosis is involved in the mechanisms underlying BTF. Our results showed that in ischemia/reperfusion injured rats BTF could dose-dependently reduce myocardial infarction index and myocardial enzyme leakage, and enhance heart function, indicating that it possesses significant cardio protection. ELISA analysis showed that BTF could decrease the content of myocardial inflammatory cytokines such as IL-1beta, IL-6 and TNF-alpha. Western-blotting confirmed that BTF could increase the expression of anti-apoptotic protein Bcl-2 and reduce the expression of proapoptosis protein Bax. Further more, the phosphorylation level of PI3K and Akt was upregulated by BTF treatment. BTF can protect rat against myocardial ischemia/reperfusion injury. Anti-inflammation and inhibition of apoptosis through upregulating PI3K/Akt signal pathway may contribute to the protective effect of BTF.

The choice of specific promoters used within a transgene construct is a vital strategy to achieve the transgene regulation in the temporal, spatial and measurable manner. The strategy has been widely used in diverse aspects of plant gene engineering, such as quality improvement, resistance breeding and bioreactor. In this paper, we describe the structure feature, classification and research method of the specific promoter and its application progresses in plant gene engineering.

Objective To study systemic hematogenic immunoreactions induced by bacterial infections using simulation of natural system.Methods Whole blood 0.2 mL or white blood cells 0.2 mL and plasma(or normal saline)0.3 mL were stimulated by 0.2 mL of yeast and inactivated Bacillus Calmette-Guerin(BCG,5?10~8/mL),respectively,which were incubated at 37℃for 1 h. Interleukin(IL)-8,C3,C4 and chemokine receptor Fy6 were detected by flow cytometry(FCM)and en- zyme-linked immunosorbentassay(ELISA).Results Bacteria could activate red blood cell to modulate IL-8 release from white blood cells in plasma.In nature experimental group,activation rate(37.04?34.84)of IL-8 was significantly higher than that(1.09?0.77)in isolation experimental group.In nature experimen- tal group,value increment(0.01?0.01)of complement C4 was significantly higher than that(-0.0027?0.008)of isolation experimental group(P

OBJECTIVETo investigate the variance of antibiotic resistance of Acinetobacter Baumanii isolated from children in Wuhan between 2006 and 2008.
METHODSBacterial susceptibility testing was carried out by the Kirby-Bauer method in 679 strains of Acinetobacter Baumanii isolated in Wuhan Children's Hospital between 2006 and 2008. The results were assessed according to the guidelines of the Clinical and Laboratory Standards Institute (2008).
RESULTSThe nonsusceptible rates of Acinetobacter Baumanii to ceftazidime, cefepime and piperacillin/sulbactam increased significantly in 2007 compared with those in 2006 (P<0.05). By comparing the results of 2007, it was suggested that the nonsusceptible rates of Acinetobacter Baumanii to ceftazidime, cefepime, piperacillin/sulbactam, cefoperazone/sulbactam, imipenem and meropenem increased significantly in 2008 (P < 0.05).
CONCLUSIONSThe nonsusceptible rates of Acinetobacter Baumanii to beta-lactam antibiotics in children from Wuhan increased significantly year by year between 2006 and 2008.

This study was to investigate the protective effects of puerarin on myocardial ischemia/reperfusion (MI/R) injury and the underlying mechanism. The MI/R-model was established by ligating the left anterior descending artery (LAD) for 60 min followed by 24 h reperfusion, puerarin (10, 30, and 100 mg·kg-1) was orally administered 20 min before reperfusion. Cardiac function, myocardial infarct index, cardiac damage markers, inflammatory cytokines, and apoptosis index were measured to evaluate the protective effects of puerarin on MI/R injury. The activation of Nod-like receptor protein 3 (NLRP3) inflammasome and Toll like receptor 4 (TLR4)/myeloid differentiation factor 88 (Myd88)/nuclear factor kappa B (NF-
