Single cells were acutely isolated from pregnant human myometrial smooth muscles. Whole-cell Ca^2＋-activated K^＋ currents were recorded by using an Axopatchl-D amplifier. The cells were divided into three groups： group A in which AM was added into perfusate, group B, in which interleukin-6 was added into perfusate） and group C in which AM was added into perfusate after addition of interleukin-6. IL-6 10 ng/mL inhibited BKca by 36.9%±13.7% as compared with control （P〈0.01）. AM at 2 mg/mL raised BKca by 36.7%±22.6% or 45.2%±13.7% with or without the treatment of IL-6, respectively （P〈0.01）. It is concluded that AM was able to enhance the BKca of pregnant human myometrial smooth muscle cells treated or untreated with interleukin-6 and its effect on the BKca IL-treated cells was stronger that its effect on BKca of untreated cells. Our results suggested that AM can help to maintain the membrane potentials and the resting status of pregnant human myometrial smooth muscle cells.展开更多

Methods: the samples of Atractylodes macrocephala Koidz were treated with different baking temperatures, baking time, humidity, open space time, sample morphology and other conditions. The contents of Atractylodes macrocephala Koidz I, II and III were determined by HPLC, and the change rules were analyzed. Results: for the original medicinal materials and decoction pieces, temperature and heating time had a certain effect on the conversion amount, but the effect was limited. However, under the influence of the appropriate heating temperature and heating time, the content of pulverized sample powder changed significantly. In the case of Atractylodes macrocephala Koidz in the form of powder, with the increase of storage time, the content of Atractylenolide I, II and III changed significantly. Conclusion: comparison of the content change law of Atractylodes macrocephala Koidz lactone I, II, III is conducive to optimizing the processing method of Atractylodes macrocephala Koidz, and provides a reference for the quality control of Atractylodes macrocephala Koidz.展开更多

In the present study, we determined the effects of polysaccharides extracts from these two herbs on IEC-6 cell migration and explored the potential underlying mechanisms. A migration model with IEC-6 cells was induced using a single-edged razor blade along the diameter of cell layers in six-well polystyrene plates. The cells were grown in control--media or media containing spermidine(5 μmol·L^(-1), SPD), alpha-difluoromethylornithine(2.5 mmol·L^(-1), DFMO), 4-Aminopyridine-(40 μ-mol·L^(-1), 4-AP), the polysaccharide extracts of RA or RAM(50, 100, or 200 mg·L^(-1)), DFMO plus SPD, or DFMO plus polysaccharide extracts of RA or RAM for 12 or 24 h. Next, cytosolic free Ca^(2+)([Ca^(2+)]cyt) was measured using laser confocal microscopy, and cellular polyamine content was quantified with HPLC. Kv1.1 mRNA expression was assessed using RT-qPCR and Kv1.1 and RhoA protein expressions were measured with Western blotting analysis. A cell migration assay was carried out using Image-Pro Plus software. In addition, GC-MS was introduced to analyze the monosaccharide composition of both polysaccharide extracts. The resutls showed that treatment with polysaccharide extracts of RA or RAM significantly increased cellular polyamine content, elevated [Ca^(2+)]cyt and accelerated migration of IEC-6 cells, compared with the controls(P < 0.01). Polysaccharide extracts not only reversed the inhibitory effects of DFMO on cellular polyamine content and [Ca^(2+)]cyt, but also restored IEC-6 cell migration to control level(P < 0.01 or < 0.05). Kv1.1 mRNA and protein expressions were increased(P < 0.05) after polysaccharide extract treatment in polyamine-deficient IEC-6 cells and RhoA protein expression was increased. Molar ratios of D-ribose, D-arabinose, L-rhamnose, D-mannose, D-glucose, and D-galactose was 1.0:14.1:0.3:19.9:181.3:6.3 in RA and 1.0:4.3:0.1:5.7:2.8:2.2 in RAM. In conclusion, treatment with RA and RAM polysaccharide extracts stimulated migration of intestinal epithelial cells via a polyamine-Kv1.1 channel activated signaling pathway, which facilitated intestinal injury healing.展开更多

The resutls showed that treatment with polysaccharide extracts of RA or RAM significantly increased cellular polyamine content, elevated [Ca^(2+)]cyt and accelerated migration of IEC-6 cells, compared with the controls(P < 0.01). Polysaccharide extracts not only reversed the inhibitory effects of DFMO on cellular polyamine content and [Ca^(2+)]cyt, but also restored IEC-6 cell migration to control level(P < 0.01 or < 0.05). Kv1.1 mRNA and protein expressions were increased(P < 0.05) after polysaccharide extract treatment in polyamine-deficient IEC-6 cells and RhoA protein expression was increased. Molar ratios of D-ribose, D-arabinose, L-rhamnose, D-mannose, D-glucose, and D-galactose was 1.0:14.1:0.3:19.9:181.3:6.3 in RA and 1.0:4.3:0.1:5.7:2.8:2.2 in RAM. In conclusion, treatment with RA and RAM polysaccharide extracts stimulated migration of intestinal epithelial cells via a polyamine-Kv1.1 channel activated signaling pathway, which facilitated intestinal injury healing.

文摘We developed an efficient plant regeneration protocol for rapidly propagating Atractylodes macrocephala Koidz,an important traditional Chinese medicinal plant,via shoot organogenesis.Shoot multiplication was induced on Murashige-Skoog(MS)medium supplemented with various concentrations of N-phenyl-N-1,2,3-thidiazol-5-ylurea(TDZ),6-benzylaminopurine(BA)andα-naphthaleneacetic acid(NAA).Rooting was induced on half-strength MS medium supplemented with NAA and indolebutyric acid(IBA).The maximum mean number of shoots(5.61)was obtained from a single explant by the combined effect of 1.08μmol/L NAA and 2.25μmol/L TDZ.The longest roots and a minimum number of roots were produced when they were cultured in a medium without plant growth regulators.The shortest roots and the largest number of roots were observed in the medium supplemented with 2.7μmol/L NAA.
文摘Two new sesquiterpenes: beishulenolide A 1 and peroxiatractylenolide III 2 wereisolated from Atraclylodes macrocephala Koids (compositae).Their structures were elucidated onthe basis of spectral evidence, especially 2D-NMR methods and chemical conversion.
