Résumé
Cancer-related fatigue (CRF) belongs to the category of "consumptive disease" in TCM, and its occurrence is based on "internal deficiency" of the body causing by the tumor. Its nature is intermingled deficiency and excess. Its pathogenesis is the deficiency of qi, blood, yin and yang and zang-fu viscera dysfunction caused by disorders of "rise and fall of middle qi" and kidney origin depletion. The theory of "treating overstrain syndrome with warming methods" originates from Huang Di Nei Jing, which proposes that warming methods are the basic methods of treating consumptive disease. Therefore, starting from the cause and pathogenesis of CRF, this article sorted out the theoretical origin of "treating overstrain syndrome with warming methods", and discussed the clinical application of warming methods for the treatment of CRF combining with modern clinical research, with the purpose to provide references for clinical practice.

Objective To observe the effects of different doses of Sappan Lignum and Chuanxiong Rhizoma on tumor stem cells marker ABCG2 in vivo. Methods Sphere cells obtained from serum culture were inoculated in nude mouse armpit, which were randomly divided into 5 groups: control group, Sappan Lignum high- and low-dose groups, and Chuanxiong Rhizoma high- and low-dose groups. Each medication group was given relevant medicine for gavage. 21 days later, inhibition tumor rate and ABCG2 protein and mRNA expression were detected with confocal microscope, Western blot, and RT-PCR. Results The sphere cells obtained from serum free culture had the abilities of cancer stem cells, such as proliferation, anti-aptosis and high expression of cancer stem cells markers. Chuanxiong Rhizoma high- and low-dose groups could inhibit tumor growth (P0.05). Compared with the control group, Chuanxiong Rhizoma low-dose group could significantly inhibit the expression of resistant protein of ABCG2. Sappan Lignum high- and low-dose groups could not inhibit the protein expression of ABCG2. Each medication group up-regulated the mRNA expression of ABCG2 except for Chuanxiong Rhizoma low-dose group. Conclusion Low dose of Chuanxiong Rhizoma can inhibit the expression of ABCG2 protein levels, which can be the targeting killer for cancer stem cells.
Résumé
The invasion and metastasis of tumor as the primary cause of death in cancer increases not only the patient's suffering, but also the difficulty of clinical treatment. It is an important guiding to find the molecular biological tumor markers and gene targets of antirecurrence and antimetastasis for clinical treatment. The invasion and metastasis of tumor is a complex process including the biological characteristics of the cancer, interaction among host cells, extracellular matrix and cancer cells, etc. Recently, epithelial mesenchymal transition (EMT) is becoming a hot spot in oncology research by virtue of its effect on genesis and development of tumor. Currently, the known markers of EMT include epithelial marker proteins mainly containing E-cadherin and interstitial marker proteins mainly containing N-cadherin and vimentin. It is necessary to make a summary among the studies on three proteins.

Objective To investigate the Effect of Tetramethylpyrazine on adhesion and invasion ability of Cell PG in Hypoxic Environment. Methods The revival cell PG was divided into three dosages(high, medium and low)group of Tetramethylpyrazine, DDP group and negative control group. All of five groups were cultured separately in the normal and hypoxic environment. The adhesion ability of Cell PG were detected by MTT. The invasion ability of Cell PG were detected by Transwell chamber. Results Observed on the reconstruction of the basement membrane adhesion in PG cells by MTT, in normoxic environment the mean absorbance of the TMP high, medium and low concentrations, cisplatin group, control group were (0.556±0.040),(0.519±0.056), (0.517±0.061),(0.333±0.057),(0.300±0.066), P<0.01. In hypoxic environment the mean absorbance of the TMP high , medium and low concentrations, cisplatin group, control group were (0.48±0.032),(0.452±0.059),(0.274±0.093),(0.464±0.099),(0.155±0.042), P<0.01. Promotion of cell adhesion with Tetramethylpyrazine of high, medium and low concentration group and DDP group in hypoxic environment is greater than in normoxic environment(P<0.01). Observed the reconstruction of the invasion of basement membrane of PG cells by Transwell chamber, in normoxic environment the invasive cells of the TMP high, medium and low concentrations, cisplatin group, control group were :(28.00±17.00),(91.67±30.37),(105.67±39.58),(85.00±8.19),(152.33±24.71), P<0.05.
