ABSTRACT
AIM: To observe the effect of piceatannol on the kidney of diabetic nephropathy rats in early stage, and to explore the possible mechanisms.METHODS: The rats were randomly divided into 5 groups: control group, model group, low dose of piceatannol treatment group, medium dose of piceatannol treatment group and high dose of piceatannol treatment group.The rat model of diabetic nephropathy was induced accordingly, and the rats received 20 mg/kg, 40 mg/kg or 60 mg/kg of piceatannol by gavage once a day for 4 weeks.Blood glucose was detected by glucometer.The urea nitrogen and creatinine levels in the serum were measured by urease-glutamate dehydrogenase enzymatic and inosine acid oxidase methods, respectively, and 24 h urinary microalbumin was analyzed by immune transmission turbidimetry test.Moreover, the pathological changes of the kidney tissues were observed under microscope with HE staining.The protein expression of TGF-β1 and Smad 7 and the phosphorylation levels of Smad2 and Smad3 were determined by Western blot.RESULTS: Compared with model group, piceatannol treatment significantly decreased the levels of blood glucose, blood urea nitrogen and urinary microalbumin, but had no effects on serum creatinine.Furthermore, HE staining showed that the increased mesangial cells, matrix hyperplasia and degenerated epithelial cells in model group were markedly inhibited after piceatannol treatment.Additionally, piceatannol treatment also reduced the protein expression of TGF-β1 and Smad 7, and the phosphorylation levels of Smad2 and Smad3.CONCLUSION: Piceatannol attenuates pathological progression in the kidney of diabetic nephropathy rats in early stage, which may be through inhibiting TGF-β/Smad signaling pathway.

ABSTRACT
Epidermal growth factor (EGF) is an epithelial cell growth factor that can stimulate intestinal development, repair the damage of epidermal cells as well as reduce the incidence of pathogen infection and diarrhea. In order to produce a recombinant Lactobacillus plantarum (L. plantarum) expressing porcine epidermal growth factor (pEGF), we constructed a recombinant vector stably expressing pEGF in L. plantarum strains. First, L. plantarum strain Lp-1 was isolated from intestinal contents of piglets. Then the functional domain of pEGF, M6 precursor protein signal peptide (SP) and super strong constitutive promoter (SCP) were connected with the backbone plasmid pIAβ8 to construct the recombinant vector that was transformed into Lp-1 by electroporation. Afterwards, pEGF was expressed in Lp-1 and detected by Tricine-SDS-PAGE and ELISA. After orally irrigated early-weaned BALB/c mice with the recombinant L. plantarum every morning and late afternoon for 10 consecutive days, body weight, villous height and crypt depth in the intestine were measured to examine the influence of the recombinant bacteria on the intestinal development of early-weaned mice in vivo. Finally, the results of our experiments demonstrated that pEGF was successfully expressed in Lp-1 and the molecular weight of pEGF was 6 kDa. In addition, the recombinant pEGF can enhanced the daily gain and exerted significance influence (P < 0.05) to the small intestinal morphology of early-weaned BALB/c mice. In conclusion, pEGF could be expressed in L. plantarum and the recombinant pEGF possesses good biological activity.

Objective To study the effects of exogenous hormones,gibberellin(GA3)and indole-3-acetic acid(IAA),on growth and tanshinones accumulation in the radix of Salvia miltiorrhiza.MethodsThe herb characters and contents of tanshinones(cryptotanshinone,tanshinone Ⅰ,and tanshinone ⅡA)in the radix of S.miltiorrhiza with different hormone treatments were investigated and compared in the combination of trail pot and indoor analysis.Results It promoted aboveground biomass in the radix of S.miltiorrhiza increasing with single GA3.But it inhibited underground biomass increasing.The exogenous addition of low-level and high-level GA3 was benefit for tanshinones accumulation,whereas the middle-level GA3 wasn't.The aboveground and underground biomass in the radix of S.miltiorrhiza increased indistinctively with the increasing of IAA concentration and then decreased.And the IAA solutions also increased plant height and root length indistinctively.in a whole,it was benefit for tanshinones accumulation when applying low-level IAA(0.5 mg/L)singly.With the increasing of IAA concentration,the content of cryptotanshinone increased,but the contents of tanshinone Ⅰ and tanshinone ⅡA decreased.It promoted S.miltiorrhiza radix growth and three tanshinones contents increasing obviously with the combined application of two low-level hormones.Conclusion The applying of GA3 and IAA is benefit for the growth and three tanshinones accumulation in the radix of S.miltiorrhiza.

Objective To compare the botanical characters, yield, and active components in flowers of seven various cultivars from Chrysanthemum morifolium in planting base in Sheyang County, Northern Jiangsu Province and provide the theoretical and practical basis for plangting and expanding reproduction of improved cultivars of C. morifolium. Methods Based on the field experiment, comparison, and analysis of the botanical characters, yield, and active components (total flavonoid and chlorogenic acid) in flowers of the seven cultivars from C. morifolium, such as “Hongxinbaiju”, “Changbanbaiju”, and “Hubaiju” etc. Results The botanical characters of flowers are vary different among the seven cultivars from medicinal C. morifolium in the planting base; the amount of single capitulum is the main factor influencing on the yield of C. morifolium, the yield of “Hongxinbaiju” is the highest; the contents of total flavonoid and chlorogenic acid of “Changbanbaiju” are the highest in the seven cultivars. Conclusion From all the aspects, in the planting base of Northern Jiangsu Province, “Hongxinbaiju” and “Changbanbaiju” can be extended as major cultivars with good characters of superior quality and high yield, “Hubaiju” and “Huangjuhua” also can be cultivated at present.
