Cancer is one of the leading causes of human death, despite enormous efforts to explore cancer biology and develop anticancer therapies. The main challenges in cancer research are establishing an efficient tumor microenvironment in vitro and exploring efficient means for screening anticancer drugs to reveal the nature of cancer and develop treatments. The tumor microenvironment possesses human-specific biophysical and biochemical factors that are difficult to recapitulate in conventional in vitro planar cell models and in vivo animal models. Therefore, model limitations have hindered the translation of basic research findings to clinical applications. In this review, we introduce the recent progress in tumor-on-a-chip devices for cancer biology research, medicine assessment, and biomedical applications in detail. The emerging tumor-on-a-chip platforms integrating 3D cell culture, microfluidic technology, and tissue engineering have successfully mimicked the pivotal structural and functional characteristics of the in vivo tumor microenvironment. The recent advances in tumor-on-a-chip platforms for cancer biology studies and biomedical applications are detailed and analyzed in this review. This review should be valuable for further understanding the mechanisms of the tumor evolution process, screening anticancer drugs, and developing cancer therapies, and it addresses the challenges and potential opportunities in predicting drug screening and cancer treatment.

Burn injuries are a significant global public health concern. The psychological problems deserve more attention. Research has shown that reducing the stigma and improving the burn patient’s self-esteem are effective means to promote social reintegration. The aim of this study is to explore the relationship between stigma and self-esteem and to examine the independent factors that contribute to with the stigma of burns. The convenience sampling method was used in Guangzhou, China. A cross-sectional study was conducted using the Social Impact Scale, Rosenberg Self-Esteem Scale, and a sociodemographic questionnaire. Descriptive statistics, statistical inference, correlation testing, and regression analysis were used to analyze the data among 146 burn survivors. The P-value was set as .05. The mean score of SIS was 57.03 ± 6.762. Of the four components of the Social Impact Scale, social rejection had the highest mean score (21.72 ± 3.00). The mean Self-Esteem Scale score was 21.05 ± 2.492, markedly different from the general population. A moderate positive correlation (r = .546, P < .001) was found between stigma and low self-esteem among burn victims. Multiple linear regression analysis identified residence, itching, and Self-Esteem Scale score as significant influencing factors, accounting for 38.5% of the total variance in stigma. Burn survivors reported moderate levels of stigma and low levels of self-esteem. Residence, itching, and Self-Esteem Scale score were significant influencing factors for stigma. To promote recovery of patients with burn injury, it is necessary to eliminate the stigma and improve their self-esteem.
