    [Objective]To explore the inhibiting effect of ursolic acid on human hepatocarcinoma cell line SMMC-7721. [Methods]Human hepatocarcinoma cell line SMMC-7721 was co-cultured with ursolic acid of different concentrations. After cultured for 24 and 72 h,the absorbancy was determined by neutral red stain. And with it,we could evaluate the inhibiting effect of ursolic acid on the proliferation of hepatoma cell line. The effect of ursolic acid on cell apoptosis and cell cycle of hepatoma carcinoma cell was determined by flow cytometry. [Results] The inhibiting effect of ursolic acid on the proliferation of SMMC-7721 cell was significant( P < 0. 05 or P < 0. 01) and it was time dependent and dose-dependent. The median inhibitory concentrations( IC 50) of 24 and 72 h were 12.59 and 8.32 mg/L. The detection result of flow cytometry indicated that apoptosis rate of ursolic acid on human hepatocarcinoma cell line SMMC-7721 reached 14. 07%. And the apoptosis rate rose with the increase of drug concentration. Ursolic acid could block the S phase of SMMC-7721 cell and its effect was positively correlated with dose. [Conclusions] Ursolic acid could significantly inhibit the proliferation of human hepatocarcinoma cell line SMMC-7721. And the antitumor effect of which might be correlated with its effect of inducing cell apoptosis and blocking cell cycle to S phase.

    [Objective]To clone the key enzyme oxidosqualene cyclases( OSC,EC 4. 2. 1. B2) at the downstream of saponin biosynthetic pathway of Panax quinquefolius( American ginseng),and to analyze its expression pattern. [Methods]Employing high throughput ESTs sequencing and RACE technology,the OSC gene involving dammarane sapogenin biosynthesis in American ginseng was cloned and analyzed. [Results]Full length cDNA of OSC gene was cloned from American ginseng and accessed in GenBank( accession No. GU997679). It was nominated by PqDS,with nucleotide length of 2 310 bp and containing one open reading frame encoding 769 amino acids. Structural domain analysis showed that PqDS contains the conserved active site and motif of OSC. Signal peptide analysis using Singal P3. 0 indicated that American ginseng PqDS belongs to non-secreting protein. Real-time fluorescence quantitative PCR analysis detected that it expresses highest in flower organ and relatively in root,leaf and stem.

They were sham operation group,ovariectomized group,nilestriol group,low-,medium-, and high-dosage Murraya exotica( L.) group. Ovariectomized rats were duplicated as a model,0. 8% CMC- Na was administrated to rats in sham operation group and ovariectomized group after operation. Rats in nilestriol group was administrated according to the dose of 0. 5 mg / kg. After eight weeks of administration,the weight of uterus and the contents of estradiol in the serum were determined,the contents of hyaluronic acid in the serum and synovia were also determined.

  • Problems Existing in the Production of Angelica sinensis( Oliv. ) Diels in HuiChuan Town Producing Region and Corresponding Solutions

    Fenglin LIU;Lei ZHAO;Pengfei XIA;Zhijia CUI;

    At present,there exist two major problems in Angelica sinensis( Oliv.) Diels production in HuiChuan Town producing region, which include breeding and local poor Angelica sinensis processing technology. For the breeding and cultivation,there is no professional seed production institutes or company and cultivation areas extend toward low elevation area,which lead to the increase of early bolting rate and degeneration of A. sinensis varieties,severely affecting the quantity and quality of A. sinensis. In regard the processing,the rainy climate in HuiChuan Town producing region has determined that the drying method of A. sinensis after harvest is smoke drying. Although smoke drying is favorable for the drying and preservation of A. sinensis,it consumes a large amount of firewood that causes a high cost,and it shows a poor prevention effect on damages caused by worms in Spring. Thus,traditional burning sulfur fumigation is always adopted for antimoth at the Awakening from Hibernation,which causes the overproof of sulfur dioxide,severely affecting the quality of medicinal materials. To fundamentally solve above problems,concern and effort should be paid on the following aspects:( 1) enhancing seedling quality;( 2) strengthening the stewardship during nursery period;( 3) strengthening the stewardship during cultivation period;( 4) enhancing harvest quality;( 5) monitoring breeding quality;( 6) monitoring processing quality. Meanwhile,professional industrialized nursery institutes and the specialty cooperation of farmers must be established for breeding high quality seeds at elevation regions. Moreover,nursery facility conditions should also be improved to ensure the quality of seed seedlings. In conclusion,we can ensure the enhancement of both preservation and processing qualities of A. sinensis,by strengthening the technical training of farmers on processing A. sinensis after harvest,together with the design and construction of large scale facilities for smoking drying.

    Qin LUO;Xiaoqun DUAN;Shaoye XU;Shaorui SONG;Hui SHEN;

    [Objective]To establish a new simple and steady diabetic foot ulcer model for the clinical and basic study of diabetic skin ulcer. [Methods]Five pigs were randomly divided into control group( n =2) and experiment group( n =3). Pigs in control group were fed with basal diet while those in experimental group were fed with high-fat and high-sucrose diet. When the model was established,the skin ulcer was burned on back,neck and limbs of the pigs after anesthesia. The wounds were examined by histological analysis and the areas of wounds were measured at different time points. [Results]Diabetic models were successfully established,there were no significant differences in morphology of ulcers in both groups. Weights of pigs in both groups increased and the food and water intake changed a little. Ulcers in both groups stayed unhealed after 4 weeks. After 4 weeks,the ulcers were examined by histological analysis. The structure of the epidermis and dermis were disappeared along with cell degeneration. The histopathological changes of subcutaneous fatty tissue and underlying muscle tissue were characterized by degeneration. [Conclusions] The animal model can simulate clinical diabetic skin ulcer and the method of establishing such model is easy and reliable.
