Breast cancer (BC) is a serious worldwide disease that threatens women's health. Particularly, the morbidity of triple-negative breast cancer (TNBC) is higher than that of other BC types due to its high molecular heterogeneity, metastatic potential and poor prognosis. TNBC lacks of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), so there are still no effective treatment methods for TNBC. Here, we reviewed the classification of TNBC, its molecular mechanisms of pathogenesis, treatment methods and prognosis. Finding effective targets is critical for the treatment of TNBC. Also, refining the classification of TNBC is benefited to choose the treatment of TNBC, because the sensitivity of chemotherapy is different in different TNBC. Some new treatment methods have been proposed in recent years, such as nutritional therapy and noncoding RNA treatment methods. There are some disadvantages, such as the side effect on normal cells after nutrient deprivation, low specificity and instability of noncoding RNA. More studies are necessary to improve the treatment of TNBC.

Interferometry is a widely used technique for real-time monitoring of concentration variation during processes in a solution like crystal growth and dissolution. This paper reports a protein concentration measurement system using a conventional Mach–Zehnder interferometer that allows monitoring the time course evolution of the protein concentration distribution during the processes of crystallization or dissolution. The demonstrated method showed improved reliability and versatility in that it (1) enables measurements under versatile temperature conditions and (2) eliminates the unpredictable errors caused by the environmental disturbances. The measurement system described in this paper can also be applied in measurements in other solution systems.
