Cancer Research and Clinic 2017;29(2):133-137
Neoadjuvant chemotherapy (NAC) has been widely used in ⅡA, ⅡB, ⅢA stage and locally advanced breast cancer. The best way to evaluate NAC effect is to detect the changes in total tumor lesion volume by three-dimensional reconstruction under magnetic resonance imaging (MRI). At present, it is a hotspot for many scholars to effectively evaluate the efficacy of NAC and the impact of shrinkage modes on the evaluation after NAC in breast cancer by combination of multiple parameters, such as the area under receiver operating characteristic curve (ROC), time-intensity curve (TIC) type and minimum apparent diffusion coefficient (ADC). To provide more practical and accurate means and methods in evaluating the effect of NAC in breast cancer for clinic is the medical researchers′eternal target.

The damage to the barrier of colonic mucosal epithelial cells is the fundamental cause of bacterial translocation.The tight junction among epithelial cells forms the most important constituent part of the mechanical barrier of the organism to prevent bacterial translocation from happening in the intestinal canal.The para-colonic-mucosal-epithelial-cell space is closed by protein complexes which are considered to be used for regulating the permeability between cells.ZO-1,Claudin-1 and Occludin are the most representative among the numerous protein complexes.They have become the important index to judge the damage degree of the barrier of colonic mucosal epithelial cells in test.The endotoxin is the product released by bacteria.Anti-endotoxin is one of the methods to protect the colonic mucosal barrier,to prevent and treat bacterial translocation.There are anti-endotoxin drugs.However,there has not been any drug widely recognized clinically up to now.Qingyi Decoction and Chaiqin Chengqi Decoction are the traditional Chinese medicine with the function of protecting the intestinal mucosal barrier and suppressing the transloeation of enteric bacteria.Oxymatrine has many pharmacological effects such as anti-bacterial,anti-inflammatory and immunoragulation.The recent animal experiments showed that oxymatrine has protective effect on the intestinal mucosa during severe infection.However,the mechanism of the drug action has not been completely known and needs to be studied in depth.Our traditional Chinese medicine applies extensively in clinical application of the prevention of the damage to the colonic mucosal epithelial cells during severe infection.
