On connotation of Jin's three-needle technique / 中国针灸

Jin's three-needle technique is named after Professor JIN Rui. The connotation of Jin's three-needle technique is summarized by his followers through long-term teaching and clinical practice. His principle and method of point combination are based on syndrome differentiation of acupuncture. And his unique needling technique and treating principle of mental tranquilization also play an important role in his clinical practice.

Involvement of LMO4 in tumorigenesis associated epithelial-mesenchymal transition / 浙江大学学报·医学版

LMO4 is a novel member of the LIM-only (LMO) subfamily of LIM domain-containing transcription factors, so named because they are composed almost entirely of two tandem LIM domains. This subgroup of LIM proteins has 4 members: LMO-1, LMO-2, LMO-3 and LMO-4. They all play important roles in the normal mammalian development, functioning as an important regulator of cell proliferation. LMO4 is highly expressed in the epithelial compartments at locations of active epithelial-mesenchymal interactions, and can interact with some signaling pathways involved in epithelial-mesenchymal signaling. Thus the disregulation of LMO4 expression may be involved in tumorigenesis. In this paper, we will at first expound LMO4 in detail, based on which the possible mechanisms for its interaction with TGF-β signaling and the roles of this cross-talk between them in the vital process of cell will be introduced. All of those will add to our understanding of tumorigenesis and contribute to the search of new targets for the treatment of cancer.

Fibroblasts-colorectal cancer cells interaction induces the expression of IGFBP7 / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the impact of intracellular interaction between fibroblasts and colorectal cancer cells on the expression of insulin growth factor binding protein7 (IGFBP7).</p><p><b>METHODS</b>Colorectal cancer cells SW480 were cultured with or without fibroblasts HELF cells in RPMI 1640 medium for 0 h, 48 h, 7 2 h and 96 h, respectively. By RT-PCR and immunohistochemical staining methods,the expression of IGFBP7 was detected in mono-and co-cultured cells.</p><p><b>RESULT</b>When SW480 cells were co-cultured with HELF cells, IGFBP7 expression in SW480 cells was significantly upregulated. Furthermore, IGFBP7 was induced in HELF cells both at mRNA and protein levels, which did not express when cells were mono-cultured.</p><p><b>CONCLUSION</b>Fibroblasts-colorectal cancer cells interaction induces the expression of IGFBP7, which indicates tumor-stroma interactions may play an important role in colorectal cancer development.</p>
