Small cell lung cancer(SCLC),a highly aggressive malignancy,is rapidly at an extensive stage once diagnosed and is one of the leading causes of death from *** the past decade,the treatment of SCLC has largely remained unchanged,and chemotherapy remains the cornerstone of SCLC *** therapeutic value of adding immune checkpoint inhibitors to chemotherapy for SCLC is low,and only a few SCLC patients have shown a response to immune checkpoint *** tumor cells(CTCs)are tumor cells shed from solid tumor masses into the peripheral circulation and are key to tumor ***-cell sequencing has revealed that the genetic profiles of individual CTCs are highly heterogeneous and contribute to the poor outcome and prognosis of SCLC ***,phenotypic analysis of CTCs may be able to predict the diagnostic significance of new potential targets for metastatic *** this paper,we will discuss in depth the heterogeneity of CTCs in SCLC and the value of CTCs for the diagnosis and prognosis of SCLC and as relevant tumor markers in metastatic SCLC.

Colorectal cancer(CRC) constitutes the third most frequently reported malignancy in the male population and the second most common in women in the last two decades. Colon carcinogenesis is a complex, multifactorial event, resulting from genetic and epigenetic aberrations, the impact of environmental factors, as well as the disturbance of the gut microbial ecosystem. The relationship between the intestinal microbiome and carcinogenesis was relatively undervalued in the last decade. However, its remarkable effect on metabolic and immune functions on the host has been in the spotlight as of recent years. There is a strong relationship between gut microbiome dysbiosis, bowel pathogenicity and responsiveness to anti-cancer treatment;including immunotherapy. Modifications of bacteriome consistency are closely associated with the immunologic response to immunotherapeutic agents. This condition that implies the necessity of gut microbiome manipulation. Thus, creatingan optimal response for CRC patients to immunotherapeutic agents. In this paper, we will review the current literature observing how gut microbiota influence the response of immunotherapy on CRC patients.

Recent progress in fluorescent and colorimetric sensors for the detection of ions and biomolecules

Chinese Chemical Letters 2018年第11期29卷 1545-1559页

作者： Le Yu Yimu Qiao Lanxi Miao Yanqi He Ying Zhou College of Chemical Science and Technology Yunnan University

Optical sensors are widely used in the field of analytical sensing and optical imaging because of their high sensitivity, fast response time, and technical simplicity. The advantages of sensors lay in their non- invasive approach within biological tissues and inherent reliability in fluorescence imaging tests. In recent years the development of optical sensors for the sensing of ions, neutral molecules and especially tumor micro-environment-related parameters has been an active research area. This review focuses on recent contributions concerning fluorescent or colorimetric sensors and is organized according to their target classifications.
