Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

Objective To investigate the relationship between NF-?B activation and the expression of metastasis correlation factors.Methods The expression of NF-?B,COX-2,ICAM-1,VCAM-1 and MMP9 in colorectal cancer and normal tissues was detected using Western blotting.Results(1)The expression level of NF-?B was higher in cancer tissues than that in normal tissues(P

Objective To explore the mechanism of endotoxemic injury in kidneys and protective effect of dexamethasone on renal cells.Methods Fifty-four eighteen-day Wistar rats were divided into control,endotoxemic(LPS)and dexamethasone groups randomly,18 rats in every group.Rats in control group were injected intraperitoneally with the same volume(0.1 mL)of 9 g/L sodium chloride as other two groups.All rats in LPS group were injected with a single bolus of LPS(4 mg/kg).The rats in dexamethasone group received LPS(4 mg/kg)and dexamethasone(5 mg/kg).Then they were sacrificed at 6,24 and 72 hours after injection.The ultrastructure was observed by electron microscope.Results In LPS group,glomerular basement membrane became thick and foot processes had coalescent partly,mitochondrial cristae became dissolved in proximal tubular endothelial cells and microvillus of distal tubular diminished at 6,24 hours after LPS injection.The morphological changes of apoptosis were found in the proximal tubular at 72 hours after LPS injection.These changes were in dexamethasone group.Conclusion Apoptosis participates in LPS injury of kidneys and dexamethasone have protective effect on injuried renal cells.

Objective To evaluate the effect of collagen shield delivering fluconazole eye drops made by centrifugal method on treating fungal keratitis of rabbit eyes.Methods Using centrifugal method to make corneal collagen shield,after soaked with fluconazole eye drops,the collagen shields were used to treat fungal keratitis of rabbit eyes.Results The healing focus time of collagen shield delivering fluconazole eye drops group was average 11 days,the healing focus time of only delivering fluconazole eye drops group was average 18 days.The cure rate and effective rate of 2 groups were 78.94%,63.15% and 92.10%,78.94%,there were significance between 2 groups(P<0.05).Conclusion It was innovation for corneal collagen shield delivering fluconazole eye drops made by centrifugal method to cure fungal keratitis,which had broad development foreground.

0.05).92.7%of the objects knew that passive smoking was harmful.71.9%knew that passive smoking made people suffering from cardiopathy more possibly.74.9%knew that the wife whose husband smoked were easier to catch lung cancer.And 84.4%knew that the child whose parent s smoked more possibly took asthma or respiration disease. The correct rates of the four knowledge points were different among different gender and the degree of education,which was higher in female than in male,and higher in high education degree than in the other(P

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.

OBJECTIVETo analyze current stroke prevention measures for elderly patients with atrial fibrillation.

METHODSA retrospective analysis was conducted of the clinical records of elderly patients with atrial fibrillation treated in our hospital within the recent 5 years. The distribution of high risk factors for different age levels was studied, and the incidence of stroke and complications such as hemorrhage were compared between patients treated with warfarin and aspirin therapy.

RESULTSCompared with patients of 65 to 75 years old, the incidence of complications with other high risk factors was increased in advanced age group (over 75 years). Of these patients, 19.0% were treated with warfarin and 73.4% with aspirin. Compared with the aspirin group, stroke incidence was decreased significantly in warfarin group, which had simultaneously increased nonfatal hemorrhage.

CONCLUSIONWarfarin can be more effective than aspirin for stroke prevention in elderly patients with atrial fibrillation, but in clinical practice, the usage rate of warfarin still remains low with insufficient monitoring.

Clinical trial protocol is the document that illustrates the background of a clinical trial, theoretic basis, objective, design, methods, and organization, as well as statistical calculating, implement, and conditions for completion. Clinical trial protocol is the basic measure for ensuring the validity of scientific results and reducing bias. In order to optimize the design of clinical trial protocol, we generalize main problems in Chinese medicine clinical trials, key points of clinical trial protocol, as well as report standards.
