Lung cancer is a worldwide leading cause of cancer-related death. The aim of this study was to identify target genes and specific biomarkers for identification and treatment of different types of lung cancer with DNA microarray. Gene expression profile GSE6044 and miRNA microarray profile GSE17681 were downloaded from Gene Expression Omnibus database. The differentially expressed genes (DEGs) and miRNAs were screened with multtest package in R language. Then, functional enrichment analysis of identified DEGs was performed. Furthermore, the verified target genes based on screened miRNAs were selected from miRTarBase and miRecords databases. Then miRNA-target gene regulation network was constructed. APOE, CDC6 and ATP2B1were involved in most of the functions obtained for adenocarcinomas, small cell lung cancer and squamous cell carcinomas, respectively. The target DEGs of differentially expressed hsa-miR-29a included FGG in adenocarcinoma, RAN and COL4A1 in small cell lung cancer, GLUL in squamous cell carcinoma. The target DEGs of has-miR-7 were SNCA and SLC7A5 in adenocarcinoma and small cell lung cancer, respectively. ICAM1 and KIT were the target DEGs of hsa-miR-222 in adenocarcinoma and squamous cell carcinoma. The miRNAs and their differentially expressed target genes have the potential to be used in clinic for diagnosis and treatment of different kinds of lung cancer in the future. © 2014, Springer Science+Business Media Dordrecht.

Background: Given limited health sources, how to make DRGs (Diagnosis Related Groups) more feasible is a big question in developing countries. This study contributes to the debate on how to bridge the pay-for-service and DRGs during the transitional period of payment reform. Methods: From 2008 to 2012, 20740 patients with cirrhosis or duodenal ulcer disease were chosen as sample. Using multiple linear regression analysis, the interrelationships between the total medical expenses of the inpatients, and age, gender of the inpatients, length of stay (LOS), region and economic level of the hospitals were examined. Results: The main findings were 1) length of stay (LOS) and the economic level of treatment location had a statistically significant impact on patients with cirrhosis or duodenal ulcer disease. Meanwhile gender is not a significant factor for both of them. 2) Under the premise of limited resources, developing countries should first narrow down to screen for common and frequently occurring diseases, then study the key factors which affect the treatment cost of the diseases. Conclusion: Based on picking out common diseases and their key factors, Simplification of the DRGs setting process will greatly increase the efficiency of implementing DRGs in the developing world.

AIM: To study the lung cancer caused by smoking from RNA-seq data and its mechanism at molecular level. MATERIALS AND METHODS: We downloaded gene expression profile SRA (Sequence Read Archive) data from Gene Expression Omnibus database that included two samples: one was lung cancer tissue samples from smoker (GSM718710) and the other was from non-smoker (GSM718709). We analyzed differential expression of genes with packages software TopHat and Cufflinks, and did Gene Ontology (GO) function clustering of the differentially expressed genes by BLASTX. Then we utilized KEGG Or-thology Based Annotation System (KOBAS) to make pathway annotation and do enrichment analysis of KEGG pathway. After that, we searched for probable alternative splicing of the selected differentially expressed genes and found closely-linked genes. RESULTS: we screened 1603 differentially expressed genes, most of which were involved in cellular processes. We also identified that the possible alternative splicing of gene FCGBP might have an important impact on lung cancer. CONCLUSIONS: These findings in this study may help better understand the relationship between smoking and lung cancer pathogenesis.

Objective: With the success of DRGs (Diagnosis Related Groups) in developing countries, this prospective payment system has been imported into China from the early 21st century. However, DRGs has been struggling and has made little progress since (its adoption in) 2004. This study contributes to the debate on how to bridge the pay-for-service (system/scheme) and DRGs (Diagnosis Related Groups) during the transitional period of payment reform in China. Methods: From 2008 to 2012, sixty regional general hospitals in Shanghai were divided into three groups according to their economic level, and one hospital was picked from each group randomly. After ranking of morbidity, 22130 patients with hypertension or coronary heart disease were chosen as sample. Using multiple linear regression analysis, the inter relationships between the total medical expenses of the inpatients, and age, gender of the inpatients, length of stay, region and economic level of the hospitals were examined. Results: The main findings were (1) Age, LOS and the economic level of treatment location had a statistically significant impact on patients with hypertension or coronary heart disease. However, gender is only a significant factor to patients with coronary heart disease. The results suggested that age, LOS and the economic level of treatment location should be considered in formulating pricing standards for the hypertension patient group. Besides the above mentioned factors, gender should also be considered in formulating pricing standards for the coronary heart disease patient group. (2) Under the premise of limited resources, developing countries should first narrow down to screen for common and frequently occurring diseases, then study the key factors which affect the treatment cost of the diseases. Conclusions: Simplification of the DRGs standard- setting process based on standardized clinical pathways and accurate costing will greatly increase the efficiency of implementing DRGs in the developing world.

Endometriosis is defined by presence of endometrial glands and stroma outside the uterine cavity and it affects approximately 5%-10% of women of reproductive age. Although endometriosis is usually considered to be due to retrograde menstruation, the true pathogenesis of this disease remains poorly understood. Endometriosis is associated with an inflammatory response and this inflammation leads to endothelial dysfunction and might even lead to carcinogenesis. Here, we review our current understanding of the role of inflammatory processes in the pathogenesis of endometriosis.

The role of p53 codon 72 polymorphism in the development of lung cancer remains obscure due to inconsistent findings of individual case-control studies published to date. A meta-analysis was conducted to better estimate the association between the p53 codon 72 variant and lung cancer risk. All relevant publications from the PubMed, Embase, Web of Science, and Wanfang databases were retrieved. Based on the inclusion criteria, 39 publications involving 44 independent case-control studies were finally included into this meta-analysis. Data were extracted and the pooled odds ratio (OR) with the corresponding 95 % confidence interval (95 % CI) was calculated. The overall pooled ORs showed no significant relationship of the p53 codon 72 polymorphism with increased or decreased risk of lung cancer in all gene contrast models (OR Pro vs. Arg = 1.04, 95 % CI = 0.96-1.13, POR < 0.001; ORPro/Pro vs. Arg/Arg = 1.07, 95 % CI = 0.91-1.25, POR < 0.001; ORArg/Pro vs. Arg/Arg =1.04, 95 % CI = 0.94-1.15, P OR < 0.001; ORPro/Pro + Arg/Pro vs. Arg/Arg = 1.04, 95 % CI = 0.94-1.16, POR < 0.001; OR Pro/Pro vs. Arg/Arg + Arg/Pro = 1.07, 95 % CI = 0.93-1.23, P OR < 0.001). According to the ethnicity, no significant association was observed in subgroup analyses of the Asians, Caucasians, Africans and the mixed population. Similar finding was found in subgroup analyses of hospital-based and population-based studies. Concerning the histological types of lung cancer, the p53 codon 72 variant exerts risk effect on the lung carcinogenesis in patients with adenocarcinoma (OR Arg/Pro vs. Arg/Arg = 1.10, 95 % CI = 1.00-1.22, POR = 0.048). Additionally, subgroup analysis by the smoking status demonstrated that the p53 codon 72 variant seemed to play a protective role in lung carcinogenesis among the non-smokers but not the smokers in the contrast model of Arg/Pro vs. Arg/Arg (ORArg/Pro vs. Arg/Arg = 0.71, 95 % CI = 0.50-1.00, P OR = 0.049). The present meta-analysis suggests the p53 codon 72 polymorphism may weakly modify the risk for lung cancer among the adenocarcinoma patients and non-smokers. Nevertheless, this association needs further confirmation in future studies with high quality. © 2013 International Society of Oncology and BioMarkers (ISOBM).
