1.Non-small cell lung cancer staging system and the implication of 7th lung cancer TNM classification
Journal of International Oncology 2013;40(7):523-526
The TNM staging is the most common tumor staging system of lung cancer.The new revisioned 7th lung cancer TNM staging is published by the international association for the study of lung cancer (IASLC) in the 13th world conference on lung cancer.Accurate clinical staging depends on the multi-analysis from medical histroy,clinical examination,imaging examination and invasive test,which has important significance for guiding the treatment of lung cancer.The 7th lung cancer TNM classification has been revised respectively from the primary focus,lymph node metastasis and remote viscera metastasis,so as to make it more accurately corresponding to the prognosis of patients.

Aim To investigate the effects of Curcumin on Heme oxygenase isozymes in SH-SY5Y cells and explore a new mechanism of Curcumin in neuroprotection. Methods The human SH-SY5Y cells were cultured in vitro and treated with Curcumin at 0,1.25,5.0,20 ?mol?L-1 for 24 h,or with Curcumin at 5.0 ?mol?L-1 for 0,12,24,and 48 h. The active oxygen was detected by fluorescent probe DCFH-DA and fluorospectro-photometer. RT-PCR was used to detect the expression of HO-1 and HO-2 mRNA. Western blot was performed to detect the levels of HO-1 and HO-2 protein.Results The results showed that Curcumin could inhibit the levels of active oxygen(P

Aim To investigate the effect of Curcumin on the expression of HO-1 and Nrf-2,and explore the machanism of neuroprotection of Curcumin. Methods SH-SY5Y cells were treated with Curcumin at 0,1. 25, 5. 0,20. 0 ?mol?L -1,or with Curcumin at 5. 0?mol? L -1 for 12,24,48 h for the time course assay. RT-PCR and Western blot assays were carried out to detect mRNA and protein expression of Nrf-2 and HO-1. Nrf-2 siRNA was used to dectect the expression of HO-1 with the absence of Nrf-2. Results RT-PCR and Westernblot results indicated that the mRNA and protein expression of HO-1 and Nrf-2 all increased in a dose-and time-dependent manner after Curcumin treatment in the SH-SY5Y cells ( P

Objective To study the effect of the intervention mode of MTP on use of antibacterials in upper respiratory infection.Methods Adopt retrospective method to select randomly prescriptions of upper respiratory infection from July to September in 2006 for baseline investigation in Outpatient Clinic of Respiratory Department of the First People's Hospital of the city of Zhuhai in Guangdong province.Then aim physicians was interfered by MTP and investigation of post-interference was carried out after a month.The process of intervention and investigation was carried out repeatedly until June in 2007.The ratio of antibacterials use,injection use percentage and average drug fee was observed in pre/post-interference.Results The ratio of antibacterials use in upper respiratory infection in our hospital was decreased from 81.33% to 0,and the ratio percentage of injection use and average drug fee decreased by 81.69% and 35.47% respectively after four MTP circulations.Conclusion The intervention mode of MTP is feasible and effective on promoting the rational use of antibacterials on upper respiratory infection in Outpatient Clinic of Respiratory Department of our hospital.

OBJECTIVETo investigate the influence of mTOR expression on prognosis of early stage NSCLC.
METHODSOne-hundred and thirty-eight patients who underwent radical surgery for early stage NSCLC in our hospital from Janurary 2002 to December 2006 were included in this study. There were 83 males and 55 females, in an average age of 65.8 years, for both genders). The influence of age, gender, tumor typing, pathological grading, pathological staging and mTOR expression on patients' survival were analyzed by univariate and multivariate analyses.
RESULTSThe 5-year survival rate of the 138 cases was 44.8%. Immunohistochemical examination showed that mTOR-positive cases accounted for 101 while mTOR-negative cases accounted for 37. The 5-year survival rate of mTOR-positive patients was 32.7% and that of mTOR-negative patients was 56.4% (P = 0.019). Univariate analysis showed that mTOR expression, pathological staging and N1 lymph node metastasis were identified as significant prognostic factors, and were correlated to prognosis (P < 0.05 for all). Multivaraite analysis showed that pathological staging, mTOR expression, N1 lymph node involvement were identified as independent prognostic factors for patients with early NSCLC (P < 0.05 for all).
CONCLUSIONSOur findings suggest that overexpression of mTOR indicates a poor prognosis for NSCLC. mTOR, pathological stage and N1 lymph node metastasis are independent prognostic factors in early stage NSCLC.

To develop a high-yield pyruvate strain, we first engineered a pyruvate-producing Escherichia coli KLPP from wild-type E. coli MG1655 by blocking the pathways for byproduct formation via gene knockout. Then, we built a library of mutant containing 7 197 monoclones by using the pUT Mini-Tn5 transposon vector for random mutagenesis with E. coli KLPP. We developed a high-throughput method for pyruvate detection based on dinitrophenylhydrazine reaction using 96-well microplate reader. After two-round screening we successfully obtained six mutants with increased pyruvate titer using this method, the titer of pyruvate was increased by 38%, 31%, 19%, 28%, 44% and 14%, respectively. The position of transposon insertion was determined by whole genome re-sequencing, and the gene locus possibly influencing pyruvate production was analyzed, which laid the foundation for subsequent strain improvement by metabolic engineering.

Despite complications were significantly reduced due to the popularity of percutaneous coronary intervention (PCI) in clinical trials, reperfusion injury and chronic cardiac remodeling significantly contribute to poor prognosis and rehabilitation in AMI patients. We revealed the effects of HSP47 on myocardial ischemia-reperfusion injury (IRI) and shed light on the underlying molecular mechanism. We generated adult mice with lentivirus-mediated or miRNA (mi1/133TS)-aided cardiac fibroblast-selective HSP47 overexpression. Myocardial IRI was induced by 45-min occlusion of the left anterior descending (LAD) artery followed by 24 h reperfusion in mice, while ischemia-mediated cardiac remodeling was induced by four weeks of reperfusion. Also, the role of HSP47 in fibrogenesis was evaluated in cardiac fibroblasts following hypoxia-reoxygenation (HR). Extensive HSP47 was observed in murine infarcted hearts, human ischemic hearts, and cardiac fibroblasts and accelerated oxidative stress and apoptosis after myocardial IRI. Cardiac fibroblast-selective HSP47 overexpression exacerbated cardiac dysfunction caused by chronic myocardial IRI and presented deteriorative fibrosis and cell proliferation. HSP47 upregulation in cardiac fibroblasts promoted TGFβ1-Smad4 pathway activation and Smad4 deubiquitination by recruiting ubiquitin-specific peptidase 10 (USP10) in fibroblasts. However, cardiac fibroblast specific USP10 deficiency abolished HSP47-mediated fibrogenesis in hearts. Moreover, blockage of HSP47 with Col003 disturbed fibrogenesis in fibroblasts following HR. Altogether, cardiac fibroblast HSP47 aggravates fibrosis post-myocardial IRI by enhancing USP10-dependent Smad4 deubiquitination, which provided a potential strategy for myocardial IRI and cardiac remodeling.
