OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.
METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.
RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

OBJECTIVETo study the molecular mechanism of curcumin in human esophageal carcinoma cell line (EC109).
METHODSEC109 cells were cultivated in vitro. When 80%-90% confluence was reached, they were treated with curcumin in different concentrations (15-120 µmol/L). The effects on cell proliferation were examined by CCK-8 colorimetry. The ultrastructure of EC109 cells were detected with transmission electron microscope(TEM). The cells apoptosis was observed with laser confocal microscope(LCM) by AnnexinV-FITC/PI double staining. The proteins level of PTEN, AKT, GSK3β and Caspase 3 were tested by flow cytometry(FCM) .
RESULTSCCK-8 test showed that curcumin could inhibit the proliferation of EC109 cells in a time- and concentration-dependent manner. TEM and LCM examinations indicated that curcumin could make EC109 cells apoptosis. The data of FCM showed that curcumin could increase the expression of PTEN, GSK3β and Caspase 3, decreased the expression of AKT.
CONCLUSIONThe effects of curcumin on inhibiting proliferation and promoting apoptosis of EC109 cells were related with increased expression of PTEN and inhibition of PI3K/AKT signaling pathway.

1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to evaluate the quality of 21 Farfarae Flos (FF) samples from different growth regions. Principal component analysis showed that wild and cultivated FF could be separated clearly, suggesting a big chemical difference existed between them. Supervised PLS-DA analysis indicated that the wild samples showed higher levels of secondary metabolites, such as bauer-7-ene-3β, 16α-diol, chlorogenic acid, rutin, 7-(3'-ethylcrotonoyloxy)-1α-(2'-methyl-butyryloxy)-3, 14-dehydro-Z-notonipetranone (EMDNT), tussilagone, β-sitosterol and sitosterone. This is consistent with traditional experience that the quality of wild samples are better than that of cultivated ones. The content of pyrrolizidine alkaloids senkirkine also differed greatly among samples from different habitats. The Pearson correlation analysis showed that senkirkine is positively correlated with 4, 5-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid, 3,4-O-dicaffeoylquinic acid, rutin, kampferol analogues, to a statistically significant extent. The correlation between the toxic compounds and the bioactive components in FF should be further studied.

AIM: To investigate the effects of angiotensin-converting enzyme inhibitors (ACEI), fosinopril, captopril and angiotensin II AT 1 antagonists, valsartan on tissue factor (TF) expression on monocytes induced by lipopolysaccharide (LPS). METHODS: Mononuclear leukocytes from normal delivered female umbilical veins were incubated with bacterial LPS in presence or absence of different ACE inhibitors .At the end of incubation, the cells were disrupted by 3 freeze-thaw cycles. TF procoagulant activity was assessed by a one-stage clotting assay. RT-PCR was used to check TF mRNA expression, and GAPDH mRNA was used for parallel assay. RESULTS and CONCLUSION: The results showed that increased expression of TF mRNA induced by LPS was inhibited by fosinopril, captopril and valsartan, respectively, and the procoagualant activity of monocytes was also reduced.
