[Objective] This study was to study the optimal extraction technology and anti-inflammatory effects of colchicine from Sagittaria sagittifolia. [Method] The ef- fects of ethanol concentration, extraction time, extraction temperature and solid-liquid ratio on the extraction rate of colchicine from S. sagittifolia were investigated. On the basis of single-factor experiments, an L9 （34） orthogonal test was carried out to optimize the extraction process. According to the optimal extraction process, the content of colchicine in S. sagittifolia was determined by high performance liquid chromatography. The anti-inflammatory ability of colchicine was evaluated through an anti-inflammatory test in vitro. [Result] The optimal extraction process of colchicine from S. sagittifolia was as follows： ethanol concentration of 60%, extraction temper- ature of 50℃, extraction time of 30 min, and solid-liquid ratio of 1：25 （g/ml）. The content of colchicine in S. sagittifolia was determined as 40.58 μg/100 mg. Com- pared with the control, the colchicine from S. sagittifolia （9.0 and 4.5 g/kg） inhibited the increase in PGE2, TNF-α and IL-1β contents in pleural fluid （P〈0.05）. High-dose colchicine inhibited the increase in TNF-α, IL-1β and MDA contents in lung tissue （P〈0.01）, and middle-dose colchicine inhibited the increase in IL-1β content in lung tissue （P〈0.01）. [Conclusion] The colchicine in S. sagittifolia has a good anti-inflam- matory effect, which may be achieved through hindering the production of inflam- matory mediators and antioxidation.

Electrospinning of a sandwich-structured membrane with sustained release capability and long-term anti-inflammatory effects for dental pulp regeneration

Current electro spun membranes used for pulp capping still lack the sustained-release capability and long-term anti-inflammatory effects that are favorable for dental pulp regeneration.In this work,a single-layered poly(lac tic acid)(PLA)electro spun membrane loaded with amorphous calcium phosphate(ACP)and aspirin(PLA/ACP/Aspirin membrane,i.e.,PA A membrane)is sandwiched between two poly(lactic-co-glycolic acid)(PLGA)electro spun membranes as a novel sandwich-structured PLGA and PA A composite electro spun membrane(PLGA-PAA membrane)to resolve the need for sustained-release design and anti-inflammatory effects.Contact angle measurements indicate that the PLGA-PAA membrane is more hydrophilic than the PAA membrane.An in vitro release study reveals that PLGA membranes coated on PAA membrane could slightly slow down ion release,while signiificantly prolonging aspirin release.We also co-cultured membranes with dental pulp stem cells(DPSCs)and human monocytic THP-1 cells to evaluate their osteogenic ability and anti-inflammatory effects,respectively.Compared with the PAA membrane,the PLGA-PAA membrane promotes cell adhesion,proliferation,and osteogenic differentiation.A prolonged anti-inflammatory effect of up to 18 days is also observed in the PLGA-PAA group.The results suggest a promising strategy for fabricating an electro spun membrane system with controlled release capabilities and long-term anti-inflammatory effects for use as pulp-capping material for regeneration of the dentin-pulp complex.

Aim To evaluate the anti-inflammatory effects of ethanol fraction prepared from Disporum cantoniense （Lour.） Merr. 70% ethanol extract with a cellular model of LPS-stimulated RAW264.7 cell. Methods RAW264.7 cells were treated with different concentrations of ethanol fraction （25,50 and 100 g · L^-1 ） and stimu- the conditioned media was collected and analyzed. The quantity of ni- lated with LPS （10 μg· L^-1） for 24 hours, tric oxide （NO） was assayed by Griess reagent. The production of inflammatory mediators was determined by en- zyme-linked immunosorbent assay （ELISA）, such as prostaglandin E2 （PGE2）, tumor necrosis factor ot （TNF-ot） interleukin- 1 β （IL-1 β） and interleukin 6 （IL-6） in cell supernatant. The concentrations of inflammatory medi- 9 ators were calculated according to the standard curves generated by each of the recombinant cytokines provided with LPS can induce RAW264.7 cells to promote the pro- the ELISA kits. Results Compared with the control group, TNF-α, IL-1β and IL-6. Compared with the duction of inflammatory mediators （P 〈 0.01 ） , including NO, PGE2, model group, ethanol fraction significantly suppressed LPS induced release of inflammatory mediators such as nitric NO, PGE2, TNF-α, IL-1β and IL-6 in a good dose dependent manner （P 〈 0.05, P 〈 0.01 ）. Conclusions Eth- anol fraction could significantly inhibit the production of LPS-induced inflammatory response in RAW264.7 cells, and its anti-inflammatory effect may be related to reduce the production of inflammatory mediators NO, PGE2, TNF-α, IL-1 β and IL-6. These results demonstrate that the ethanol fraction is the bioactive component of Disporum can- toniense （Lour.） Merr. , and the ethanol fraction will be further developed as a herbal remedy for preventive and/ or curative purposes in various inflammatory diseases.
