Objective To examine the metabolic variations in liver after 30 min warm ischemic injury,and the effect of hypothermic machine perfusion on the metabolism in rats.Methods 40 SD male rats were randomly divided into 4 groups:Group A,the liver underwent warm ischemia for 0 min and cold storage (CS) for5 h; Group B,the liver was treated by warm ischemia for0 min,CS for4 h and then machine perfusion (MP) for 1 h; Group C,the liver suffered from warm ischemia for 30 min and CS for 5 h; and Group D,the liver was treated by warm ischemia for 30 min plus CS for 4 h plus MP for 1 h.During the MP process,the perfusion resistance index was recorded every 10 min,and the liver glycogen content and malondialdehyde (MDA) value were also detected.Results The hepatic glycogen content decreased after MP treatment,but there was no statistical significance (P ＞ 0.05).No differences on MDA contents was found between Group A and B (P ＞ 0.05),while MDA in Group D was significantly higher than that in Group C (P ＜ 0.05).After hypothermic MP treatment,the liver resistance index value was significantly reduced.Conclusion MP could reduce the resistance index but increase metabolic rate in liver undergoing warm ischemic injury,thus producing more lipid peroxides.

italic>Alangium chinense is a commonly used medicinal plant of Alangiaceae Alangium, one of the characteristic Miao medicines in Guizhou. The genus is strongly differentiated and has complex morphological variation, with significant differences in active ingredients and potency among herbs. In this paper, we sequenced the chloroplast genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib using Illumina high-throughput sequencing technology. The genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplasts were sequenced, their assembly annotation and structural characterization were completed, and the genomes of the congeners Alangium chinense and Alangium alpinum were downloaded from NCBI for comparative analysis. Finally, the phylogenetic tree was constructed by selecting published species with close affinity to Alangium chinense family from NCBI. The results were as follows: Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplast genomes were 156 670, 156 672 and 156 871 bp in length, with a typical four-segment structure, all containing one long single copy region (LSC), one short single copy region (SSC) and two inverted repeat regions (IRa and IRb). All of them were annotated to 133 genes, including 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Three types of long repeat sequences and SSR loci, forward repeats, palindrome repeats and reverse repeats, were found in all chloroplast genomes. Comparative genomic analysis showed that there was diversity in the boundary transition regions of the five species, no rearrangements or inversions were found in the chloroplast genome, and there were significant differences in the coding regions of ndhA, ycf1, rpl16, ycf2, and petD genes, which provided new loci for molecular identification of Patagonia. In the phylogenetic analysis, Alangium kurzii var. kurzii clustered as a single species, and Alangium chinense subsp. Pauciflorum and Alangium chinense subsp. Strigosum clustered as a single species, with a support rate of 93 and close affinity, indicating that the phylogenetic tree can be used for the species identification. This paper can provide a basis for the taxonomic identification of Alangium, ensure the safety of clinical use of anise herbs and regulate the market of Alangium chinense herbs.

OBJECTIVETo research the plasmic metabolites and metabolic pathway of Xin-blood stasis syndrome (XBSS).

METHODSPlasma metabolic products in patients of coronary heart disease (CHD) with XBSS or non-XBSS and subjects in the control group were identified by gas chromatographic mass spectrometry (GC-MS) type QP2010, the changes of their main elements in different groups were analyzed by principal components analysis (PCA) and partial least squares (PLS) analysis.

RESULTSPCA showed that as compared with that in the control group, in the CHD-XBSS group, contents of lactic acid, beta-hydroxy butanoic acid, urea, oleic acid, octadecanoic acid and arachidonic acid were higher and that of citric acid was lower. PLS analysis showed significant difference between the control group and the other two groups, and the latter two groups tend to be of a same category. The occurrence of XBSS was positively correlated with octadecanoic acid, arachidonic acid, urea, lactic acid and beta-hydroxy, butanoic acid contents, and negatively correlated with oleic acid, L-proline, glycine, and citric acid contents. According to VIP, the degree of correlation between variables with drug interven- tion, from high to low, were ranked as arachidonic acid, octadecanoic acid, lactic acid, urea, beta-hydroxy butanoic acid, linoleic acid, glucose, alanine, oleic acid and proline. Discrepancy analysis on 11 changeful metabolites showed that the contents of arachidonic acid, octadecanoic acid, lactic acid, urea, beta-hydroxy butanoic acid and oleic acid increased in CHD patients, especially in those with XBSS (P < 0.01). In CHD patients, contents of lactic acid, beta-hydroxy butanoic acid, linoleic acid and glucose in patients of XBSS pattern were higher than in non-XBSS pattern (P < 0.01); content of linoleic acid, glucose, alanine and proline decreased in non-XBSS pattern while increased in XBSS pattern. Content of glucose in CHD-XBSS patients was significantly higher than that in the healthy control (P < 0.01). Content of citric acid was lower in CHD patients, and showed significant difference between that in CHD-XBSS patients and healthy control (P < 0.01).

CONCLUSIONSThe major plasmic metabolites in CHD-XBSS patients are arachidonic acid, octadecanoic acid, lactic acid, urea, citric acid, beta-hydroxybutyric acid, oleic acid, glucose, and alanine. Analyzed from plasmic metabolite spectrum view, CHD-XBSS is related with lipid metabolism and glyco-metabolism, also with the stress induced by hypoxia and agonia.

OBJECTIVETo find out the metabolite profile of rats' myocardial tissue of cardiac blood stasis syndrome (CBSS), and to analyze the metabolic pathway of CBSS rats' myocardial tissue by observing the changes of phenotypes intervened by Yangxin Tongmai Recipe (YTR).

METHODSAcute myocardial infarction (AMI) rat model of CBSS was prepared by ligating the left anterior descending coronary artery. Meanwhile, the model was interfered with YTR. The metabolites of rats' myocardial tissue were detected in the model group, the YTR group, the sham-operation group, and the blank control group using GC-MS (8 rats in each group). Changes of metabolite contents were analyzed among different groups using principal component analysis (PCA) and least-square analysis.

RESULTSAs for PCA: The results of PCA showed that principal component integral (PCI) of the four groups was mainly distributed in the three regions of oval scatterplot. The factor loading gram showed that contents of glycine, fumaric acid, malic acid, glutamic acid, glucose, phosphoric acid, galactopyranose, lysine were changed in the model group. Analysis of partial least square method: PLS regression model showed that obvious linear correlation existed between the model group and the YTR group, which proved the model was reasonably established. The drug intervention was highly positively correlated with glycine, malic acid, glutamic acid, glucose, highly correlated with urea and butanedioic acid, but negatively correlated with lysine. According to VIP value, each variable was closely correlated with the drug intervention in sequence as malic acid, glutamic acid, glycine, glucose, fumaric acid, urea, galactose, tyrosine, lactic acid, and alanine. Results of variability analysis: Obvious changed variability analysis of metabolite difference showed that 10 metabolites such as glycine, etc. obviously decreased in the model group, showing significant difference when compared with the normal group (P<0.01). Compared with the model group, contents of glycine, fumaric acid, malic acid, glutamic acid, glucose, tyrosine,urea, lactic acid, and alanine, etc. obviously increased after drug intervention (P<0.01). Of them, the increment of malic acid, glumatic acid, tyrosine, and urea was less, showing significant difference when compared with that of the normal group. The mean of lysine was slightly lowered after drug intervention, but with insignificant difference when compared with that of the model group. AMI rats of CBSS was closely correlated with myocardial metabolites such as malic acid, glutamic acid, glycine, glucose, fumaric acid, urea, galactopyranose, lactic acid, alanine, and tyrosine, etc.

CONCLUSIONSThe metabolite profile of rats' myocardial tissue showed AMI rat model of CBSS was closely correlated with post-hypoxia glucose metabolism disorder. YTR could effectively intervene this process.

BACKGROUND AND OBJECTIVERadioresistant cells in esophageal cancer is one of the important reasons for the local failure of radiotherapy. In recent years, some researchers used gene chip technology to screen the differentially expressed genes between parental and radioresistant human esophageal cancer cells. But there were some problems in these studies, for example comparing cells at only one time interval, and genetic background not matching. In this study, we selected 3 different pairs of parental and radioresistant human esophageal cancer cells, and compared the gene expression profiles by cDNA microarray at 3 time intervals to identify and analyze the differentially expressed genes between parental and radioresistant human esophageal cancer cells.

METHODSWe compared the gene expression profiles between parental cells (TE13, Seg-1, Kyse170) and radioresistant cells (TE13R, Seg-1R, Kyse170R) before, and at 8 h and 24 h after irradiation with a cDNA microarray consisting of 48 000 genes (Human Genome). We identified differentially expressed genes by Pathway and GO analyses, and verified the differentially expressed genes LEF1 and CTNNB1 by RT-PCR.

RESULTSA total of 460, 451, and 397 differentially expressed genes were found before, and at 8 h and 24 h after irradiation. After Pathway and GO analyses, 14 differentially expressed genes, participating in cell growth, apoptosis, cell cycle regulation, gene repair and signal transmission, were selected to further research. LEF1 and CTNNB1 were verified by RT-PCR, and the results were consistent with those of cDNA microarray.

CONCLUSIONSThe WNT signal pathway may be an important pathway participating in the formation of radioresistance of esophageal cancer cells. LEF1 and CTNNB1 may be the important genes causing the esophageal cancer cell radioresistance.
