Objective To evaluate the effect and mechanism of IL‐6 induced Gefitinib resistance in non small cell lung cancer (NSCLC) .Methods The sensitivity of cells to Gefitinib ,the invasion ability of cells and the expression of phosphorylated p‐mTOR was assessed by MTT assay ,Transwell assay and Western blot ,respectively .PC‐9psb388 stable over expressing human recombi‐nant IL‐6(hrIL‐6) cell line was established by transfecting PC‐9 cells with a lentivirus psb388 expressing IL‐6 and stable transfecta‐nts over‐expressing IL‐6 in human lung cancer cell line PC‐9 .The sensitivity of cells to Gefitinib ,the invasion ability ,expression of p‐mTOR were then detected .PC‐9/PC‐9psb388 xenografts were established and the expression of p‐mTOR and IL‐6 in tumor sec‐tions were then detected .Results The sensitivity of PC‐9 cells to Gefitinib was reduced by IL‐6 ,the invasion ability of PC‐9 cells and the expression of p‐mTOR was significantly increased with IL‐6 treatment .The sensitivity of PC‐9 cells to Gefitinib was promi‐nent higher in PC‐9psb388 cells ,while the invasion ability of PC‐9psb388 cells and the expression of p‐mTOR was higher than PC‐9 cells .The sensitivity to Gefitinib was improved and expression of p‐mTOR reduced in rapamycin‐treated PC‐9psb388 cells and IL‐6 stimulated PC‐9 cells .Tumor volume of PC‐9psb388 xenografts was significantly higher than that of PC‐9 cells .The expression of p‐mTOR and IL‐6 in tumor sections of PC‐9psb388 group were higher than that of PC‐9 group .Conclusion IL‐6 could elevate the expression of p‐mTOR to induce Gefitinib resistance in non small cell lung cancer (NSCLC) .

Librarians play a key role in the library information ecosystem.Librarians and library users interact and influence each other in process and use of information.Tagging defined by network users is used in description of words and phrases in different information resources.When it is used in library, user-oriented service will become the target of information service, and the role of information service persons, information organization methods and information low efficiency will change.However, rational planning of ecosystem, rational control of tagging, and improvement of librarian information literacy can reduce the negative effect of tagging.

In order to obtain the normal gait for the prosthesis-carrier with the change of external environment and gait, we designed a model of dynamic ankle prosthesis and control system and introduced the strategy of central pattern generator (CPG) about the moving trail of dynamic ankle prosthesis. The dynamic parts, which are incorporated in the model of dynamic ankle prosthesis, provide power in order to have anthropic function and character. The tool of Matlab/simulink was used to simulate the strategy. The simulation results showed that the strategy of CPG learn- ing control in this study was effective and could track the reference trail rapidly and fit the moving trail of a person's normal limb. It can make the prosthetic timely regulation and action, enhance the prosthetic intelligence. It has im- portant practical value for intelligent prosthesis development based on this analysis of technology.
