This paper revealed the accumulation regularity of polysaccharides and alcohol-soluble extracts contents of Dendrobium officinale leaves, which have provided basis for the development and utilization of the leaves. The polysaccharides and alcohol-soluble extracts contents of three D. officinale strains leaves collected in different growing periods were determined by phenol-sulfric acid method and hot-dip method respectively. The results showed that the content of polysaccharides in leaves was 4.45% -12.17%, and was about a quarter in stems. The alcohol-soluble extracts content in leaves was 7.45% - 29.34%, and was 1.5 times that of stems. The quality variation of polysaccharides in leaves was closely related to the phenophase. The leaves with lower level of metabolism in three stages: winter, early germination stage and deciduous period, which led to lower content of polysaccharides. The leaves at the vigorous growth stage with higher content of polysaccharides. The alcohol-soluble extracts were closely associated to the formation and germination of buds. The content of alcohol-soluble extracts peaked before sprout, and promoted the growth of new shoots.

OBJECTIVETo study the effect of 1,25-(OH)2D3 supplementation during gestation and lactation on TGF-β1 and Smad3 expression in lungs of rat offspring with asthma.

METHODSThirty-two female Wistar rats were randomly divided into four groups: low-, medium- and high-dose 1,25-(OH)2D3 supplementation and control groups (n=8 each). From the 7th day of gestation, the three 1,25-(OH)2D3 supplementation groups were administered with 2,10 and 20 μg/mL of 1,25-(OH)2D3 respectively every other day until weaning (rat offspring: 21 days old). The control group received normal saline instead. Then, bronchial asthma was induced in rat offspring from the 4 groups. The protein and mRNA expression of TGF-β1 and Smad3 in the lung tissue was measured by immunochemistry and RT-PCR.

RESULTSEosinophil cell infiltration and airway inflammation decreased in rat offspring from the low- and medium-dose 1,25-(OH)2D3 groups, but increased in rat offspring of the high-dose 1,25-(OH)2D3 group compared with the control group. Immunohistochemistry of lung tissues showed that the expression of TGF-β1 protein and pSmad3 decreased in rat offspring from the low- and medium-dose 1,25-(OH)2D3 groups (P<0.05), but increased significantly in rat offspring from the high-dose 1,25-(OH)2D3 group compared with the control group (P<0.05). PCR showed that the expression of TGF-β1 and Smad3 mRNA in the lung tissue decreased in rat offspring from the low- and medium-dose 1,25-(OH)2D3 groups (P<0.05), but increased significantly in rat offspring from the high-dose 1,25-(OH)2D3 group compared with the control group (P<0.05).

CONCLUSIONS1,25-(OH)2D3 supplementation plays a role in regulating the immune system in asthmatic rats. Its mechanism may be associated with regulation of the expression of TGF-β/Smad signal pathway-related proteins through the vitamin D receptor signal pathway.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.
