Guided by ZHANG Jiebin's "water-fire of life gate theory"， this paper explored the etiology， pathoge-nesis， and syndrome differentiation-based treatment approach for esophageal cancer. It is proposed that the core pathogenesis of esophageal cancer， derived from the imbalanced state of water and fire in life gate， can be summarized into three manifestations. Firstly， decline of life gate fire leads to failure of qi transformation and accumulation of phlegm and blood stasis； secondly， fire fails to warm the earth resulting in dysfunctional ascending and descending， and qi stagnation and blood stasis； thirdly， deficiency of life gate water contributs to proliferation of cancerous toxins and physical deterioration. In terms of treatment， guided by ZHANG's treatment principles for dysphagia， three treatment methods are proposed， warming and tonifying kidney yang to promote qi transformation through steaming action， warming and nourishing the spleen and stomach to restore central pivot movement， and nourishing kidney water to replenish essence and blood， then support bodily nourishment. Clinical case examples are provided to illustrate the application of these methods.

Breast cancer is a malignant tumor from normal breast epithelial. In recent years, many literature reports sought to determine the expression of predicted target genes of microRNA and their potential function, pathways and networks, which are involved in the tumorigenesis, metastasis and prognosis of breast cancer. The miR-21 has recently been found to be highly expressed in solid tumors than normal tissue, and it has exposed some layers of gene expression regulation that becomes a hot topic of breast cancer. This paper briefly reviews advances in research on miR-21 in breast cancer.

Objective To investigate the elasticity of the radial artery wall in type 2 diabetes mellitus (T2DM) patients with elastosonography. Methods A total of 37 patients with T2DM and 42 normal subjects were studied with elastosonography. The systolic diameter (Ds) and diastolic diameter (Dd) of the radial artery were measured, and the strain ratio of the blood in the radial artery to the wall of the radial artery was calculated. Results The strain ratio of the radial artery in T2DM group was significantly higher than that in normal group (P＜0.05). There was no significant difference in Ds and Dd of the radial artery between T2DM group and the control group (P＞0.05). Conclusion The early change of the radial artery wall elasticity in patients with T2DM can be assessed with elastosonography.
