    Gulijiang JIAMANBAI;Gulixila SHAPUXI;Yongshuai ZHANG;Hanipa HABUDULA;

    [Objective] To study the biological characteristics of Erythronium sibiricum seeds, so as to provide a scientific basis for domestication and introduction of E. sibiricum. [Method] The biological characteristics of E. sibiricum flowers, fruits and seeds were analyzed by using related literatures and biological knowledge. [Result] The fruit was capsule, 3 arris, fresh fruit grain diameter was 11.0-35.0 mm, longitudinal diameter was 12.0-45.5 mm, fruit weight was 0.5-4.5 g. Dry seed transverse diameter was 1.0-2.3 mm, longitudinal diameter was 1.5-4.0 mm, thickness was 1.0-1.5 mm. Seed maturity period was from the middle of June to late, grain weight was 7.8 g, seeds life force was 93.6%, and the water content was 12.04%, and the seed after 12 h, seed bibulous rate was 70%. Different concentration of seeds that carried liquid leaching significantly inhibited the germination of cabbage seeds and the growth of young roots. Besides, they could restrain the growth of the seed itself to a certain extent. Different drug treatments had no influence on the E. sibiricum seeds. The seed coat was not an obstacle for water absorption, and had obvious dormancy characteristic. The seed dormancy was mainly related with embryos form, late-maturing and inhibition substances of sprouting. [Conclusion] No obstacle about skin absorbing water is found in E. sibiricum seeds, that is, they have good water permeability. Seed coat permeability is not the reason for seed dormancy in E. sibiricum.

    Wanwen YU;Fuliang CAO;Guangliang WU;

    The study was intended to discuss the appropriate application concentrations of Mg, Zn and Mo fertilizers for high yield and good quality of leaf-use ginkgo. Effects of spraying different levels of Mg, Zn and Mo fertilizers on leaf yield and medicinal quality of two-year-old ginkgo seedlings were tested by indoor stimulation experiment and pot experiment. The main results were submitted as follows: firstly, the combined application of Mg, Zn and Mo fertilizers increased leaf thickness, leaf area, single plant leaf area, and leaf biomass. The best treatment was Mo③ (2%Mg+0.3%Zn+0.1%Mo) which increased the leaf biomass by 64.9% compared with that of control. Secondly, the positive effect of combining Mg with Zn and Mo fertilizers on chlorophyll and soluble protein contents decreased with the increasing Mg concentration. The same was also the effects of combining Zn with Mg and Mo fertilizers as well as combining Mo with Mg and Zn fertilizers on chlorophyll and soluble sugar contents. In contrast, the effect on soluble protein content correlated positively with Zn or Mo concentration. Thirdly, the combined application of Mg, Zn and Mo fertilizers increased total flavonoid and terpene lactones contents, total flavonoid and terpene lactones yields per plant. The best treatment was Mo③ which increased total flavonoid yield per plant by 2.96 times and total terpene lactones yield per plant by 1.70 times compared with that of control. Fourthly, high-concentration fertilizers as Mg④, Zn④ and Mo④ decreased the positive effect of the combined application of Mg, Zn and Mo fertilizers on some indexes to different degrees. The results indicated that appropriate concentration of the three fertilizers could increase chlorophyll, soluble sugar, soluble protein contents and improve ginkgo growth and medicinal quality, as well as increase component factors of leaf yield and medicinal quality. In the experiment, Mo③ was the perfect combination in order to increase ginkgo leaf yield and medicinal composition content and yield.

A doses strategy of selection and bacterium inhibition during agrobacter mediated genetic transformation was established. The result showed that the kanamycin of 40 mg/L was significantly influenced on callus growth, when it was 50 mg/L, the growth of callus was inhibited completely; the hygromycin of 8 mg/L was the best concentration for inhibiting the callus growth, the callus were geatly damaged and it's characters were small, browning and dying with the concentration of hygromycin up to 20 mg/L. Meanwhile, the low concentration (0.5-2.0 mg/L) of hygromycin can enhance the rate of callus differentiation. Carbenidillin is an antibacterial agent of Agrobacterium, carbenidillin had apparently influnced on growth of callus at different concentrations, and when the concentration of carbenidillin was greater than 400 mg/L, the growth of callus was effected observably.

  • Antiatherosclerosis Induced by Ligustrazine against LPS through Arachidonicacid Signaling Pathway

    Guofeng WANG;Xia ZHAO;Ning LI;Dongmei CHEN;

    [Objective] The aim is to study the effects of ligustrazine on the lipopolysaccharide (LPS)-induced inflammation activated through arachidonicacid (AA) pathway, which would provide the experimental basis for extending the clinical application of ligustrazine. [Method] The effects of ligustrazine (1 and 10 μmol/L, 6 h) on the expression levels of COX-2, 5-LOX and FLAP were investigated in LPS-treated (1 mg/L, 2 h) primary human coronary artery endothelial cells. The expression level of above proteins as well as p-P38MAPK and p-STAT3 were also studied when SB203580 (20 μmol/L, 6 h), the inhibitor of p-P38MAPK, or AG490 (20 μmol/L, 6 h), the inhibitor of JAK2, was added at the same time with ligustrazine. [Result] Ligustrazine obviously inhibited the expression levels of 5-LOX and FLAP, as well as the phosphorylation activation of MAPK and STAT pathways. [Conclusion] Ligustrazine targeted on endothelial cells can inhibit inflammation activated through AA pathway, as well as the activation of MAPK and JAK2/STAT3 pathways.

  • ITS-based Identification of Manyleaf Paris Rhizome and Its Adulterants

    Li JIANG;Chun ZHANG;Nong ZHOU;Qin SUN;

    [Objective] To discriminate manyleaf paris rhizome and its commonly mixed adulterants by ITS sequence analysis. [Method] The experimental materials included manyleaf paris rhizome samples collected from Yunnan Province and Sichuan Province, commercial manyleaf paris rhizome samples purchased from market and the control Yunan manyleaf paris rhizome. The ITS fragments of these materials were amplified using specific primers for bidirectional sequencing. The sequencing results were multiply aligned by software Clustal W, based on which the mutated sites were analyzed by PAUP 4.0b10 for constructing the phylogenetic tree (most parsimony, MP). [Results] The ITS length of the samples varied between 622-639 bp, of which there were 53 mutated sites in ITS1 sequence, more than that in ITS2 and 5.8 s regions. Phylogenetic analysis showed that the manyleaf paris rhizome samples collected from various origins fell into a different branch. From the phylogenetic tree, there are 14 identification sites among manyleaf paris rhizome and adulterants in sequence alignment plot. [Conclusion] The ITS sequence can distinguish the genuine Paris and its adulterants. But more specific markers for accurate and rapid identification purposes should be exploited, combined with other gene sequences, to distinguish analogue materials with close genetic relationship.

    Qilai CHENG;Meixiang LIAO;Zhiqin HUANG;

    [Objective] To study the Ilexgenin A-induced apoptosis in cervical cancer HeLa cells and its mechanism. [Methods] DAPI was adopted for nucleus stain to observe the morphological change during apoptosis; Apo-ONE Homogeneous protease -3/7 kit was used for measure the activity of Caspase -3/7; and the binding activity of nuclear extracts of cervical cancer HeLa cells NF-κB p65 with DNA was determined to investigate the activation level of NF-κB. [Results] DAPI assay showed that karyopyknosis and chromatin condensation occurred and apoptotic bodies appeared 24 h after Ilexgenin A (IA) induction. IA enhanced the activity of Caspase - 3/7 at the manner of dose-dependence. IA assumed remarkable inhibitory effect on the activation of subunit p65 of NF-κB, and this inhibitory effect was found dose-independent to some extent. [Conclusion] IA could remarkably induce the apoptosis in cervical cancer HeLa cells at the manner of concentration-dependence.
