Targeted therapeutic drug,having such advantages as targeting,safety,convenience,etc,is increasingly favored by non-small cell lung cancer (NSCLC) patients.At present,there are many kinds of molecular targeted drugs used in clinic,and remarkable efficacy was achieved,and the pain caused by conventional chemotherapy was avoided.At the same time,with the deepening of the understanding of the mechanism of tumor immune,new targeted drugs will also continue to be developed.The emergence of the third generation EGFR-TKI brings new hope for first generation EGFR-TKI resistant patients.Combined use of different immune therapeutic agents,combined application of immunotherapy drugs and cytotoxic chemotherapy drugs and radiotherapy,and the exploration of its predictive biomarkers will become a hot spot in the research of lung cancer.This will undoubtedly bring a new dawn for the treatment of NSCLC.Based on the domestic and foreign research literatures and related materials,this article reviews the latest research progress of various molecular targeted drugs for treatment of NSCLC.

OBJECTIVE:To provide a reference for clinical use of anti-tumor adjuvant drugs as is reasonable,effective and economical. METHODS:By retrospective investigation and analysis,the utilization of anti-tumor adjuvant drugs in the oncology department of our hospital during 2010 and 2013 was analyzed statistically in respect of the type,dosage form,consumption amount,DDDs,DDC,DUI etc. RESULTS:The anti-tumor adjuvant drugs in our hospital were dominated by injections,especial-ly domestic drugs,the consumption amount of which accounted for 80% of the total consumption amount of anti-tumor adjuvant drugs each year. The anti-tumor adjuvant drugs were mainly used for symptomatic treatment of various adverse reactions. Drug syn-chronization was relatively good each year,however,excessive use of individual drugs existed. CONCLUSIONS:Anti-tumor adju-vant drugs have relatively better synchronism in the drugs quantities and medication number. However,individual drugs have exces-sive use and other irrational use.

Cognitive dysfunction is the impairment of higher brain functions.Cognitive impairment caused by neuropsychiatric diseases has caused serious impact on patients'quality of life and the outcome of the disease.The transcranial alternating current stimulation(tACS)improves cognitive function by modulating neural oscillations of specific frequencies,affecting the release of neurotransmitters such as serotonin and dopamine,and enhancing local and distal synchronization of brain networks.Specific frequencies of tACS can improve the cognitive impairment caused by Alzheimer disease(AD),schizophrenia,and depression,among which the gamma and theta frequencies of tACS have the most significant effects on cognitive function.tACS has high safety and low operational difficulty,and has great potential to improve cognitive function.
