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.

Objective To understand the clinical characteristics of lower respiratory tract infection,pathogenic distribution and drug resistance in intensive care unit to provide a basis for reasonable use of antibiotics. Methods From January 2008 to August 2010,the clinical data from our hospital ICU impatients of lower respiratory tract infection were retrospectively analyzed. The isolated strains were identified, the antibiotic susceptibility test was performed by K-B methods and the results were read according to CLSI 2007. Results There were 509 patients, 147 cases of lower respiratory tract infection were found. Lower respiratory tract infection rate was 28.9% (147/509); 283 strains of pathogens had been isolated by culture and most of which were Gram negative bacilli(86. 9%), the other pathogens included Gram positive cocci(7.4%) and fungi(5.7%). The most common pathogens were Acinetobacter spp, Pseudomonas aeruginosa, Klebsiella pneumoniae,Stenotrophomonas oligotrophic aeromons, Fungi, Escherichia coli, Staphylococcus aureus, Burkholderia cepacia,etc,accounting for 24. 7% ,20. 5% ,12. 7% ,6. 4% ,5.7% ,5. 3% ,5.3% and 4. 6% ;The main pathogens were highly resistant to the most antibiotics. Conclusion ICU had a higher lower respiratory tract infection rate, Gram negative bacilli are the main pathogen, and showed the multi-drug resistance features to the antibiotics.

Objective To investigate the treatment of moed high anal fistula operation.Methods 110 cases of high anal fistula patients were randomly divided into the incision line selective suture group(treatment group 55 cases) and incision group(55 cases in the control group),on two groups of treatment time,the cure rate,the anal function were analyzed.Results The cure rate of the treatment group and control group were 98 ％,86％,respectively,the cure rates of two groups have no significant difference (x2 =1.557,P ＞ 0.05),the healing time and postoperative anal function evaluation in treatment group was superior than those in control group (t =3.440,4.671,all P ＜ 0.01).Conclusion Incisionunder selective suture in the treatment of high anal fistula operation is a better way.

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.

Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.

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.
