OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

Objective To investigate the feasibility, effect and mechanism of chemical bile duct embolization for chemical hepatectomy. Methods Phenol or absolute ethanol plus cyanonacrylate were employed as embolization agents. Histology, Fas and TGF-? 1 measurement were used to evaluate the result. Results Phenol plus cyanonacrylate effectively destroyed and embolized intrahepatic biliary duct, leading to complete disappearance of hepatocytes in the periphery of embolization lobe and thereby achieving the effect of chemical hepatectomy. Expression of Fas and TGF-? 1 in phenol embolism group (88.90?38.10, 185.22?70.39) and ethanol embolism group (72.39?29.51, 163.56?51.75) were higher than those in biliary duct ligated group (26.31?12.07, 74.84?40.73) ( P

The biological!activities i.e. antineoplastic activities and antiviral activity of the two novel kinds of interferons: hIFN-?1 and hIFN-? were studied and compared. First the fusion expression vector: pcDNA3.1A-hIFN-?1-His and pcDNA3.1A-hIFN-?-His by PCR was constructed,then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFN-?1-His and rhIFN-?-His, meanwhile MTT assay was used to detect their antineoplastic activities.It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-?1-His is more powerful than of rhIFN-?-His. The antiviral molecular mechanisms of both hIFN-?1 and hIFN-? are related to MxA.The foundation for further study on the bioactivities and mechanism of action of hIFN-?1 and hIFN-? was established.

The known members of inhibitor of growth (ING) gene family are considered as candidate tumor suppressor genes. ING4, a novel member of ING family, is recently reported to regulate brain tumour angiogenesis through transcriptional repression of NF-?B-responsive genes, induce G2/M arrest by the increased p21 expression in a p53-dependent manner, suppress the loss of contact inhibition and represses activation of the hypoxia inducible factor, which plays an important role in the progression of tumorigenesis. However, seldom studies about ING4 inducing tumor cells apoptosis were reported.The C6 cells (mouse glioma cells) were infected respectively with the blank adenovirus carrying GFP (Ad) and the recombinated Ad-hING4-His, then RT-PCR assay was used to detect the transcriptions of hING4, as well Western-blotting assay was ued to detect the expressions of hING4. The effects of hING4 expression upon C6 cells were observed, and the growth curve was drawed and tumor control rates were calculated. The C6 cells, which were affected by blank Ad and Ad-hING4-His, were respectively observed by LSCM (laser scan confocal microscope) and transmission electron microscope (TEM), detected by flow cytometry; and the genomic DNA of both groups were extracted and electrophoresised in agarose gel to examinate the DNA fragments. The results showed hING4 can significantly inhibit the growth of C6 cells by promoting the cell’s apoptosis, which probably is the first one to prove this property of ING4.The experimental and theoretical foundation for gene therapy for gliomas with ING4 in the future was established.

During the washing process of coarse bear gall powder extracts, it is necessary to adjust the amount of ethyl acetate according to the properties of raw materials, which aims to improving the yield and purity of the final product. In the research, using NIR spectra to reflect the comprehensive properties of coarse bear gall powder extracts, the process is optimized in a flexible way. Forty batches experiments are designed according to the weight ratio of ethyl acetate and coarse extracts of bear gall powder. The NIR spectra of the coarse extracts of bear gall powder are collected and processed using principal component analysis (PCA) method. The first 8 principal components combined with the amount of the ethyl acetate are used as the input variables, and calibration models are established to predict the yield and purity of the final product 30 batches are used as calibration set, which is used to establish the models, and other 10 batches are used as validation set, which is used for the performance appraisal of the established models. The correlation coefficients of the calibration, inner cross-validation and external validation for the purity model are 0.902, 0.896 and 0.883, respectively, and the RMSEC, RMSECV and RMSEP are 1.22%, 1.48% and 1.59%, respectively. The correlation coefficients of the calibration, inner cross-validation and external validation for the yield model are 0.921, 0.859 and 0.916, respectively, and the RMSEC, RMSECV and RMSEP are 1.39%, 1.65% and 1.53% respectively. This work demonstrated that NIR spectra combined with technology parameter could be used to predict the yield and purity of the final product. Using the established models, the most appropriate amount of the ethyl acetate can be determined according to the properties of the coarse bear gall powder extracts, and the yield and purity of the final product can be improved.
