Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)and anti-angio-genic drugs have individually demonstrated clinical benefit in the treatment of patients with advanced non-small cell lung cancer (NSCLC).Recent studies demonstrate that the combination of anti-EGFR and anti-angiogene-sis can more significantly enhance clinical benefit,and even can remit EGFR-TKIs resistance in the treatment of advanced NSCLC.According to the different kinds of anti-angiogenesis drugs,recent clinical studies mainly include the combination of anti-vascular endothelial growth factor monoclonal antibody bevacizumab plus EGFR-TKIs and multi-targeted receptor anti-angiogenic tyrosine kinase inhibitor plus EGFR-TKIs,and the for-mer results show a more significant improvement in terms of safety and efficacy in the treatment of advanced NSCLC.Therefore,the combination of bevacizumab plus EGFR-TKIs can be used as a new treatment standard in the treatment of some patients with NSCLC.

Recently, there are many prominent problems about the quality ofIndigo Naturalis. To explore the underlying reasons, both ancient and modern herbal literatures were reviewed. Through the organization of recordings onIndigo Naturalis, the traditional process method required soaking and fermentation, stiring and depositing, foaming and shade drying. The currently usedIndigo Naturalis was mostly isolated and purified from crude deposit -“Cu-Dian.” The modern process technique ofIndigo Naturalis was gradually deviated from the traditional processing method. This paper also discussed the quality standards ofIndigo Naturalis. The author considered that the current standard on descriptions ofIndigo Naturalis characteristics was deviated from the traditional morphological features ofIndigo Naturalis, which should be further researched and verified. Therefore, this study provided certain references for the quality control and market supervision ofIndigo Naturalis.
