The relationship of dose and effect in TCM formulae was an important subject in the TCM modernization research.Some characteristic properties of TCM dose-effect relationship were proposed in this paper: the dose-effect relationship of TCM had a specifi c regulation from the whole-view idea in traditional medical theories besides common properties,nonlinear character from the compatibility of medicine properties,and multi-effects varied with the different compatibility from the alternation of doses.The subjects of dose-effect relationship included single medicine,drug pair and formulae.The study on the dose-effect relationship of TCM might be helpful to the explanation of conception,connotation,ideas and methods of TCM,provide scientifi c supports and instructions for the TCM clinical practices,and provide research bases for the TCM innovation.

Objective To investigate the effects of Mus81 gene silencing on the chemosensitivity of human colon cancer HCT116 cells to oxaliplatin and explore the underlying mechanisms. Methods lentiviral-mediated RNAi was employed to inhibit Mus81 gene in human colon cancer HCT116 cells. MTT assay was employed to evaluate oxaliplatin chemosensitivity of HCT116. Cell apoptosis rate was detected by Annexin V-APC staining and the expression levels of p53, while Bax and Bcl-2 in HCT116 cells were detected by Real-time PCR and Western blot. Results Oxaliplatin IC50 of Mus81 depleted HCT116 cells was significantly decreased. After oxaliplatin treatment, the cell apoptosis rate of Mus81 silenced HCT116 cells was increased by 77.6% (P < 0.05), and the expression of p53 and Bax in these cells was obviously increased but the expression of Bcl-2 was significantly decreased (P < 0.01). Introducing Mus81 gene in Mus81 depleted HCT116 cells could reduce apoptosis rate. Conclusion Mus81 gene silencing can significantly improve oxliplatin chemosensitivity of HCT116 cells possibly by promoting cell apoptosis through regulating the expression of p53, Bax and Bcl-2.

Objective To explore the clinical diagnostic value of polyclonal all immunoglobulin.Methods The specimens of pa-tients were simultaneously tested and identified by quantitative immunoglobulins,Immunofixation electrophoresis of serum and u-rine,urine protein electrophoresis,and other ways.Results From 1 patients with rheumatoid arthritis were detected the serum IgG, M,A,KAP and LAM,and urine KAP and LAM,at the same time show the increment of the polyclonal polyclonal all immune glob-ulin hematic disease.Conclusion Polyclonal all immune globulin hematic disease often appear in the complications of chronic in-flammation,which should be paid attention during its in clinical doctors.

Ikaros represents a zinc-finger protein family important for lymphocyte development and certain other physiological processes. The number of family members is large, with alternative splicing producing various additional isoforms from each of the five homologous genes in the family. The functional forms of Ikaros proteins could be even more diverse due to protein-protein interactions readily established between family members. Emerging evidence suggests that targeting Ikaros proteins is feasible and effective in therapeutic applications, although the exact roles of Ikaros proteins remain elusive within the intricate regulatory networks in which they are involved. In this review we collect existing knowledge as to the functions, regulatory pathways, and molecular mechanisms of this family of proteins in an attempt to gain a better understanding through the comparison of activities and interactions among family members.

Nanotechnology-based photothermal therapy has attracted great attention in the past decade. Nevertheless, photothermal therapy has some inherent drawbacks, such as the uneven heat production and limited laser penetration, often leading to insufficient treatment outcomes. Here, we developed a combination strategy to improve cancer therapy. The biomimetic albumin-modified gold nanorods (AuNRs) were prepared with incorporation of paclitaxel (PTX). This therapeutic system was characterized by several features. First, the albumin modification enhanced the biocompatibility and colloidal stability. Second, the surface-coated albumin promoted cellular uptake the albumin-binding protein pathway. Third, PTX was incorporated hydrophobic interaction between PTX and the albumin lipophilic domain. Fourth, the system can be used for combined photothermo-chemotherapy for yielding synergistic effects. The antitumor activity of the system was evaluated both and using the HCT116 colon cancer cell and tumor model. The combination therapy was found with an enhanced treatment efficiency and no obvious side effect. Most importantly, the thermal effect was also discovered with the ability to modulate the tumor microenvironments and suppress the macrophages polarization towards the M2 pro-tumor phenotype. It could be a mechanism for photothermal immunotherapy. The combination strategy and the system provide a potential method for cancer therapy.
