Clinical studies have revealed that the presence of CTCs in peripheral blood is correlated with disease progression in lung cancer. However, as CTCs are rare cancer cells released from tumors into the bloodstream, both enrichment and sensitive detection methods are technically challenging. In order to best understand how CTCs are currently being deployed, this review mainly focuses on the different detection methods for CTCs. Furthermore, we will describe the clinical impact of circulating tumor cells in lung cancer and discuss their potential use as biomarker to guide the prognosis.展开更多

The method comes with less or no side effects, comparing the western medicine chemicals. With the new computer information technologies, the ancient Chinese healing tool could be very convenient for people to take care of themselves at home or work. In this paper, the authors present their online database system for locating the acupressure points. A case study shows the details of the design and structure of the online system.展开更多

It introduces the types of collocation and explores the factors that trigger cross-linguistic differences in collocation. We suggest that great attention to collocation be given in English vocabulary teaching.展开更多
