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.

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.

Objective To explore the curative effect of the single pore video-assisted thoracoscopic surgery and thoracic closed drainage for patients with acute pyothorax by comparing the advantage and disadvantage of two methods.Methods The clinical data of 65 patients with acute pyothorax in our hospital from January 2012 to June 2015 were retrospectively analyzed.Of which 30 patients underwent single pore video-assisted thoracoscopic surgery were as observation group,35 cases received thoracic closed drainage were as the control group.The cura-tive effect of two methods for acute pyothorax was compared by analyzing the result data of two groups.Results The postoperative chest tube indwelling time,length of hospital stay,postoperative antibiotics of observation group were significantly less than those of the control group,the difference was statistically significant(P<0.05).And the incidence of postoperative complications,the proportion of the chronic pyothorax and secondary tube rate of observation group were lower than those of the control group,the difference was statistically significant(P<0.05). Conclusion The single pore video-assisted thoracoscopic surgery is safe and effective for treatment of acute pyothorax, which is worth promoting.

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.

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.
