Effect and Mechanism of Curdione on Migration and Invasion of Breast Cancer HCC1937 Cells / 中国实验方剂学杂志

Objective: To investigate effect of curdione on the migration and invasion of human breast cancer HCC1937 cells and its mechanism.Method: HCC1937 cells were cultured in vitro and treated with curdione at various doses (0, 12.5, 25, 50, 100, 200, 400 μmol·L-1) for 24, 48 h, the cell viability was detected by cell counting kit-8 method. curdione groups (12.5, 25, 50 μmol·L-1) and blank group were established. The effect of curdione on the adhesion of HCC1937 cells was detected by the cell adhesion assay. The effect of curdione on migration of HCC1937 cells was detected by wound healing assay. The effect of curdione on the migration and invasion of HCC1937 cells were detected by transwell chamber assay. The effect of curdione on regulation of mitogen-activated protein kinase(MAPK)and protein kinase B(Akt)signaling pathways and the protein expressions of matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases-9 (MMP-9) of HCC1937 cells were detected by the Western blot analysis. Effect of curdione on mRNA expressions of MMP-2 and MMP-9 of HCC1937 cells were detected by Real-time PCR.Result: Compared with the blank group, curdione (12.5, 25, 50 μmol·L-1) groups had no significant effect on cell viability, but a remarkable effect on cell viability HCC1937 cells, and cell viability was gradually decreased with the increase of the concentration of curdione (PP-1) had a significant effect on cell adhesion rate, migration rate and invasion rate of HCC1937 cells (PP-1) could down-regulate phosphorylation levels of key proteins extracellular regulated protein kinases(ERK), c-Jun N-terminal kinase(JNK), Akt on MAPK and Akt signaling pathways (PConclusion: curdione can inhibit the migration and invasion of human breast cancer HCC1937 cells, and the mechanism may be related to down-regulation of phosphorylation levels of key proteins ERK, JNK, Akt on MAPK and Akt signaling pathways, so as to reduce the expressions of MMP2 and MMP-9.

Encephalopathy therapeutic tongue acupoint apparatus (ETTAA) for 42 cases of autism / 中国针灸

<p><b>OBJECTIVE</b>To observe the efficacy of encephalopathy therapeutic tongue acupoint apparatus (ETTAA) in the treatment of autism.</p><p><b>METHODS</b>Eighty-four children of autism were randomly divided into a tongue acupuncture group (group A) and a conventional training group (group B), 42 cases in each group. The behavior training and sensory integration training were carried out in group B and the ETTAA was added in group A. The apparatus was switched on for 20 min every time and 3 times a day. Treatment of two months were carried out in both groups. The score of childhood autism rating scale (CARS) and clinical efficacy in both groups were observed before and after treatment.</p><p><b>RESULTS</b>After treatment, the CARS in both groups were significantly reduced (42.39 +/- 6.86 vs 32.15 +/- 5.12, P < 0.001; 44.58 +/- 6.76 vs 39.72 +/- 7.11, P < 0.05), which was more significant in group A (P < 0.01). The totally effective rate in group A [90.5% (38/42)] was superior to that in group B [66.7% (28/42), P < 0.01].</p><p><b>CONCLUSION</b>The clinical efficacy in tongue acupuncture group is apparently superior to that in conventional training group, ETTAA combined with conventional training have a better curative effect in the treatment of autism.</p>

Tongue acupuncture / 中国针灸

Tongue acupuncture is originated from the theory of TCM through scientific research. Forty points on the tongue are discovered that correspond to organs and certain parts of the body. The findings indicate that the patient with encephalopathy is accompanied by the pathological swelling sublingual fold. The sublingual fold is correlated with spinal and limbs lesions. Tongue acupuncture provides new approaches to treat many diseases. This paper introduces the determined points, manipulation skills and the theory of tongue acupuncture. The applications of PET, fMRI and VEP in tongue acupuncture are covered in this paper.
