Extra-cellular signals, including T lymphoc ytes, cytokines,growth factors,interferons and neuropeptides, which could modulate matrix metalloproteinases expression in synoviocytes of rheumatoid arthritis(RA), are often mediated by G-protein-coupled Receptors (GPCR)-initiated signaling and mitogen-activated protein kinase (MAPK) cascades. Drug targets which aim at the extra-cellular signals or intra-cellular cascades is required for ameliorating inflammatory reaction and preventing joint destruction in RA.

Since the development of molecular biology,the treatment of advanced non-small cell cancer is shifting from traditional chemotherapy into molecular targeted therapy with genotyping as a guide′s help.The most widely used is epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs).With the appli-cation of EGFR-TKIs,the resistances to EGFR inhibitors are paid more and more attention,in recent years. The main mechanisms of acquired resistances are as follows:secondary mutation of the EGFR gene,amplifica-tion of c-MET,Her2 and other target genes,histological transformation,activation of the bypass mechanisms, loss of p53,the relief of negative feedback loops,overlap of mechanisms,etc.

The harm of tobacco is one of the most serious public health issues nowadays, and the social cost produced by smoking is increasing year by year. There are about 6 million people dying from smoking-related diseases each year, and the number of death will surpass 8 million by 2030. Helping smokers quit is the most direct and effective method to reduce the burden of disease caused by tobacco. M-health based on smartphone shows huge potential in prompting health behavior. Progress of studies on smartphone applications (APP), a new way of tobacco control, is reviewed to provide reference for future tobacco control practice and exploration.

The establishment animal model of Graves’ disease contributes to the study of etiology, pathogenesis and therapeutic modalities. After decades of studies and making improvements, the method of building mice model of Graves’disease has achieved a great development. Although there were many reports of animal model building in Graves’disease, as a mature technology A-subunit of thyrotropin receptor( TSHR)-expressing adenovirus was used to establish Graves’disease mice model, which has been accepted widely because of its high efficacy.

Objective To observe and evaluate the efficacy of the preventing antibiotic-associated diarrhea in infant with bacterial pneumonia using the live Clostridium butyricum and Bifidobacterium combined Powders. Methods 103 infants with bacterial pneumonia were randomly divided into the two groups,53 infants as the trial group,another 50 infants as the control group with normal antibacterial therapy,two or three hours afterword the live Clostridium butyricum and Bifidobacterium combined Powders was administered at dose of 0.5g ti-daily in the trial group,After diarrhea taken place,the live Clostridium butyricum and Bifidobacterium combined Powders was adminis-tered at dose of 0.5g ti-daily in the control group,to contrast the rate of secondary diarrhea and clinical efficacy in the two groups.Results The incidence of antibiotic-associated diarrhea was 13.2%( 7/53 ) in the trial group and 56.0%(28/50) in the control group (χ2 =21.00,P<0.01).There were significant differences between the two groups.Duration of diarrhea and period of treatment in the trial group was obviously shorter than that of the control group,the rate of dehydration in the trial group was lighter than that in the control group(χ2 =6.64,P<0.01). Conclusion The live Clostridium butyricum and Bifidobacterium combined powders with antibacterial therapy at reg-ular intervals can prevent antibiotic-associated diarrhea.It is worthy of preventive application.

Endothelial progenitor cells (EPCs) exist in bone marrow, umbilical cord blood and peripheral blood of adult mammals, including humans. Furthermore, the discovery of EPCs has led to the notion of adult vasculogenesis, in which bone marrow (BM)-derived EPCs home to and incorporate into sites of new blood vessel formation, where they differentiate into endothelial cells, which is consistent with postnatal vasculogenesis. It has become apparent that circulating BM-derived EPCs are involved in promoting physiologic and pathologic neovascularization, such as wound healing and tumor growth. They are of great clinical importance in pro- or anti-angiogenic therapies. [
