OBJECTIVETo study the inhibitory effect of wogonin on the growth and proliferation of breast cancer cells MDA-MB-23, and observe its effect on the adhesion, migration and invasion of MDA-MB-23 cells, in order to further study its molecular mechanism.
METHODMTT assay was used to detect the effect of wogonin on MDA-MB-23 cell growth. Ki-67 assay was adopted to test the effect of wogonin on cell proliferation. Scratch test, adherence test and invasion chamber assay were taken to detect the effect on the migration and invasion abilities of MDA-MB-231 cells. Proliferation and metastasis-related proteins and relevant signaling pathways were detected by Western blotting.
RESULTWogonin could remarkably inhibit the growth and proliferation of MDA-MB-231 cells, significantly inhibit migration, adhesion and invasion abilities of breast cancer cells at a low concentration, and effectively inhibit the expression of Survivin, Bcl-2, ICAM-1, MMP-2, MMP-9 proteins of MDA-MB-231 cells.
CONCLUSIONWogonin could notably inhibit growth and proliferation of breast cancer cells, and inhibit migration, adhesion and invasion of MDA-MB-231 cells. Its invasive and adhesive effects on MDA-MB-231 cells may be related to the decrease in ICAM-1, MMP-2, MMP-9 expressions.

Objective To study the effect of autogeneic platelet-rich fibrin (PRF) on proliferation and adipogenic differentiation of human adipose-derived stem cells (ADSCs) in vitro.Methods ADSCs were isolated from adipose tissue obtained from donors undergoing liposuction and were cultured,and underwent identification.ADSCs at passage 3 were divided into three groups:test groups were cultured with 1PRFM and 2PRFM,and control group was cultured without PRF membrane.Then the growth of the cells was observed by inverted microscope.MTT method was used to observe cell proliferation activity at days 1,2,3,4,5,6 and 7 after culture.Adipogenic differentiation of ADSCs was observed and quantified by oil red O staining at days 3,5,7,9,11 and 14.Results Cell proliferation and adipogenic differentiation would be increased with the PRFM,There were significant differences among three groups.Conclusions PRF could significantly promote proliferation and adipogenic differentiation of ADSCs.

BACKGROUND:The rabbit adipose-derived stem cells are mostly isolated by type I col agenase digestion, but rarely by explants culture method.
OBJECTIVE:To isolate rabbit adipose-derived stem cells for adipogenic and osteogenic differentiation.
METHODS:The rabbit adipose-derived stem cells were isolated from rabbit adipose by explants culture method, and cultured in vitro fol owed by morphological observation. The grow curve and cellsurface markers CD29, CD44, CD45 of passage 3 cells were analyzed respectively by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and flow cytometry;cells from the third passages were induced for adipogenic and osteogenic differentiation by different revulsants, and cells were examined by oil red O staining and alizarin red staining .
RESULTS AND CONCLUSION:The rabbit adipose-derived stem cells cultured in vitro exhibited a spindle-shaped appearance and could rapidly expand. Flow cytometry analysis revealed that the third passage of rabbit adipose-derived stem cells was positive for CD29, CD44, but negative for CD45. Rabbit adipose-derived stem cells were positive for oil red O staining at 14 days of adipogenic induction, and positive for alizarin red staining at 14 days of osteogenic induction. In conclusion, we could successful y isolate rabbit adipose-derived stem cells using explants culture method.

Objective To investigate the intervening effect of movable cupping on sub-health status. Methods Movable cupping was performed on bilateral bladder meridians and the Du meridian in 12 patients with sub-health status. The sub-health status rating scale score, the visual analogue pain intensity scale score, hemorheological parameters and immunoglobulins were observed before and after movable cupping.Results The sub-health status rating scale score, the visual analogue pain intensity scale score, whole blood viscosity 200 and plasma viscosity decreased after treatment compared with before in the patients, and there were statistically significant differences (P<0.05). Whole blood viscosity 1, whole blood viscosity 2 and whole blood viscosity 3 decreased and IgG, IgA and IgM increased after treatment compared with before in the patients, but there were no statistically significant differences (P>0.05). Conclusion Movable cupping has clinically a certain improving effect on bodily sub-health status.

?AIM:To evaluate the objective visual quality of patients who underwent corneal cross-linking for the keratoconus using double-pass analysis system.? METHODS: Advanced keratoconus patients who underwent UV - riboflavin corneal cross - linking from January to July 2015 were included. The outcomes of their objective scattering index ( OSI ) , predicted visual acuity ( VA ) , the cut - off frequency of modulation transfer function ( MTF cut- off ) , the Strehl ratio ( SR ) were compared before and 6mo after corneal cross-linking.?RESULTS: A total of 13 patients ( 16 eyes ) were included. There was no statistically significant difference between pre- and 6mo postoperative data in uncorrected visual acuity, best corrected visual acuity, refractions and mean value of Sim-k (P>0. 05). Non-invasive average tear film break up time ( NIAvg-BUT ) detected by the Sirius system decreased after corneal cross-linking ( P<0. 05 ) . Using double - pass analysis system, no statistically significant change was found in MTF cut off, Strehl Ratio, OSI before and after treatment(P>0. 05). Tear Film Analysis Mean OSI increased at 6mo postoperatively (P<0. 05).? CONCLUSION: The subjective visual quality isn’t effected by corneal cross-linking. The tear stabilities of patients are influenced by these operations at 6mo postoperatively. More observations on long-term effect are needed to be taken in the future.
