Objective:To understand the impact of adjusting national drug reimbursement list(NDRL) have on the benefits of patient covered by Basic Health Insurance ( BHI ) , medical insurance fund expenditure and specific drug marketing . Methods: Based on the survey data of medical service utilization situation of national inpatients participated BHI, to summarize and analyze the change of drug usage from 2009 to 2011. Results: In 2011, the drug expense of the national inpatient covered by BHI is approximately 132.7 billion yuan, increased by 37% compared to that of 2009; among which, the expense of entry drug accounts for about 76% out of the total drug use. In 2011, new increased expense on drug use is 13.5 billion, which increased to 98% compared to that of 2009. Conclusion:Adjustment of NDRL had little effect on total drug expenses increasing, but lead changes of the drug expense structure; and expense on some new entry drugs increased obviously. The focus of future adjustment of NRDL could gradually transfer from guaranteeing on basic medicine use to the promotion on clinical rational drug use.

Objective To explore the use of gastroscopy and CT for staging and clinical guiding to the surgical therapy of advanced gastric cancer.Methods The preoperative gastroscopic and CT classification and the results of operative classfication of 182 cases of advanced gastric carcinoma were compared.Results The resection rate for low and undifferentiated adenocarcinoma and mucinous carcinoma on gastroscopic biopsy was low(64.1%),and the rate for diffuse infiltrative gastric carcinoma(6.7%)was significantly lower than that of mass tumor type(66.7%)and ulcerative type(61.8%).The total accuracy rate of CT staging was 91.21%.Sensitivity rate of CT diagnosis of perigastric invasion and/or metastasis was 72.22%.For lymph node staging the accuracy rate of CT was 74.2%,sensitivity rate was 74.1% and specificity rate was 74.3%.CT diagnosis of lymph node groups was blur.Conclusions Gastroscopy has an unreplaceable role in the final diagnosis of advanced gastric cancer and has significance for gross tumor grading,histologic biopsy diagnosis can be as a guide to dicide the treatment modality of advanced gastric cancer.CT has high degree of value for accuracy of clinical staging,and diagnosis of invasion of adjacent organs and lymph node metastasis.CT is superior to gastroscopy for judgement of resectability.Therefore,preoperative CT is a valuable guide for surgical treatment of advanced gastric cancer.

Liver cancer has a high degree of malignancy, and many oncogenes and tumor suppressor genes play an important regulatory role in the development and progression of liver cancer. Epithelial-mesenchymal transition (EMT) is a biological process in which epithelial cells transform into mesenchymal cells, which can increase the migration and invasion abilities of tumor cells. Long non-coding RNAs (lncRNAs) can regulate EMT process in various ways. This article reviews the research advances in the main biological functions and regulatory mechanisms of EMT-related lncRNAs in liver cancer.

Objective To study the association between statins use and liver-injury through prescription sequence symmetry analysis (PSSA) and evaluate the feasibility of the method to be used in Chinese Medical Insurance Database.Methods The data of the patients who prescribed both statins and liver-proactive drugs in Chinese Basic Medical Insurance Database in 2013 were selected as study subjects to calculate the adjusted sequence ratio (ASR) with signal detection methods to determine the study parameters and investigate the potential association between statins use and liver-injury.Results In 5 649 individuals which met the inclusion criteria,the washout period was set as one month and interval period was set as 60 days.The overall ASR of statins was 1.471(95%CI:1.395-1.550),the ASR of atorvastatin was 1.419 (95%CI:1.335-1.508),the ASR of simvastatin was 1.307 (95%CI:1.164-1.467).The positive signal was strong in 30 days interval period.Conclusions PSSA indicated that there might be potential association between statins use and liver-injury,especially the uses of atorvastatin and simvastatin.This signal detection method may be a fast and effective method in drug safety evaluation and can be used in Chinese Medical Insurance Database.
