1.COX-2 and its inhibitors in lung cancer drug resistance
Journal of International Oncology 2015;(3):203-205
COX-2 is the inducible form of cyclooxygenase,which is overexpressed in non-small cell lung cancer,especially in the adenocarcinoma,and is involved in the production of lung cancer drug resistance, reducing the sensitivities of tumor cells to chemotherapy drugs. COX-2 inhibitors have the effects of antitumor and prevention of tumor formation. Therefore,in order to reverse the drug resistance of tumor cells,improve the sur-vival rate and the prognosis of patients with tumor,the application of COX-2 inhibitors as adjuvant chemotherapy and combined with chemotherapy drugs has become a new direction in the treatment of lung cancer.

Objective To explore the features of functional networks about recognizing dynamically positive expression with using magnetoencephalography (MEG) technology and the paradigm of expressional experiment, and further to examine its neurological basis. Methods Twelve depressed patients and twelve age,education-matched healthy controls participated to recognize the dynamically positive expression in the MEG scans. Results In comparison with the healthy,the abnormally activities regions in depressed patients during different time periods were separately as follow;decreased activation in the right inferior parietal lobule(t = 3.94),the right su-pramarginal gyms(t = 3.59),the bilateral posterior cingulated(t = 5. 04, t = 4. 85) ,the bilateral precuneus(t = 3.84) ,the left cuneus(t = 3.58) and increased activation in the bilateral hippocampus(t = 2. 13, t = 2.56) ,the left amygdale(t = 2.41), the bilateral uncus gyrus(t = 2.33, t = 2.44) , the right anterior cingulated (t = 2. 15) , the left fusiform gyms (t = 3. 33) (P < 0. 05, unconnected). Conclusion The results indicate, compared with healthy controls,abnormal brain activities as the weakened function of the medial temporal cortex,parietal lobe and the enhanced function of limbic system were distributed extensively in depressed patients during recognizing dynamically positive expression. These abnormalities may prompt the dynamic characteristics of the magnetic source imaging about recognizing dynamically positive expression,and further reveals the mechanisms of emotional symptoms in depression.
