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 present study was performed to investigate the effect of bicyclol on hepatic microsomal cytochrome P450 (CYP) activity, as well as gene and protein expressions in rats after partial hepatectomy (PH). Bicyclol (300 mg x kg(-1)) was given to rats subjected to 70% hepatectomy three times before operation. At 6 and 48 h after PH, blood and liver tissue samples were collected for the measurement of serum alanine aminotransferase (ALT), hepatic microsomal malondialdehyde (MDA) and total hepatic CYP content. The activities of four CYP isozymes were detected with liquid chromatography-mass spectrometry (LC-MS) and the gene and protein expressions were determined by RT-PCR and Western blotting assay. As a result, bicyclol pretreatment markedly inhibited the elevation of serum ALT and hepatic microsomal MDA, and prevented the decrease of total hepatic CYP content in PH rats. In addition, bicyclol significantly attenuated the reduction of CYP2C6 activity and mRNA expression, as well as the reduction of CYP2C11 activity in PH rats. Bicyclol can inhibit the decrease of CYP3A1/2 activity, and up-regulate the mRNA and protein expressions of CYP3A1 and CYP2E1. These results showed that bicyclol pretreatment might ameliorate abnormality in CYP450 isoforms during liver regeneration after PH, and this protective effect was likely due to its anti-oxidative property and enzyme induction.

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.

OBJECTIVETo explore the influence of methylprednisolone (MP) on cellular component in donor graft and on H-2 haploidentical hematopoietic stem cell transplantation (HSCT) in mice.
METHODSA murine model of H-2 haploidentical HSCT was established by using of c57BL/6J male mouse as donor and (c57BL/6J x LB/C) F1 female mouse as recipient. The donor mouse received peripheral-blood (PB) progenitor cells mobilization regimens consisted of recombinant human granulocyte colony-stimulating factor (rhGCSF) alone (control group) or combined with MP in dose of 2 mg/kg daily [small-dose (SD) group], 10 mg/kg daily [middle-dose (MD) group], and 50 mg/kg daily [large-dose (LD) group] respectively. Percentage of T cell subsets, DC1 (HLA-DR+CD11c+) and CD34+ cell in the grafts were detected by flow cytometry. Transplant rejection,severity of GVHD and survival time were observed.
RESULTSThe percentages of CD3+ T cell in donor grafts in the three groups were significantly lower than that in control group (P < 0.05). The percentage of CD3+ CD4+ T cells decreased more significantly than that of CD3+ CD8+ T cells, and CD4/CD8 ratios decreased significantly. The percentage of CD4+ CD25+ T cells increased significantly, the percentage of DC1( HLA-DR+CD11c+) decreased and the percentage of CD34+ cells increased in all the three groups than in control group. There were significant differences in the percentage of CD3+ T cells, CD3+ CD4+ T cells and CD34+ cells in donor grafts among SD group, MD group and LD group (P < 0.05). The engraftment rates in control, SD, MD and LD groups were 90%, 100%, 100% and 80% respectively. Severity of aGVHD in each study group decreased significantly compared with that in control group (P < 0.05). There were statistical differences among different dosage groups (P < 0.05). Survival time after transplantation in all study groups were significantly longer than that in control group (P < 0.05), and in MD group was significantly longer than in SD group and LD groups (P < 0.05).
CONCLUSIONSAddition of methylprednisolone to routine donor mice HSC mobilization regimen has a definite effect in alleviating aGVHD and prolonging survival time of mouse after H-2 haploidentical HSCT. With a suitable dosage addition of methylprednisolone to donor mice HSC mobilization regimen could avoid the increasing risk of graft rejection.
