Unstable angina（UA） is the most dangerous type of Coronary Heart Disease（CHD） to cause more and more mortal and morbid world wide. Identificat.on of biomarkers for UA at the level of prot.omics and metabolomics is a better avenue to understand the inner mechanism of it. Feature select.on based data mining met.od is better suited to identify biomarkers of UA. In this study, we carried out clinical epidemiology to collect plasmas of UA in-patients and cont.ols. Prot.omics and metabolomics data were obtained via t.o-dimensional difference gel elect.ophoresis and gas chromatography techniques. We presented a novel computat.onal strategy to select biomarkers as few as possible for UA in the t.o groups of data. Firstly, decision tree was used to select biomarkers for UA and 3-fold cross validat.on was used to evaluate computat.onal performanees for the three met.ods. Alternatively, we combined inde- pendent t test and classificat.on based data mining met.od as well as backward eliminat.on technique to select, as few as possible, protein and metabolite biomarkers with best classificat.on performances. By the met.od, we selected 6 proteins and 5 metabolites for UA. the novel met.od presented here provides a better insight into the pat.ology of a disease.

Upper triassic and Middle Jurassic strata of the Xichang Basin in Sichuan Province, southwestern China, yielded important dinosaur ichnofossils. From the Xujiahe Format.on of the Yiguojiao tracksite, we report a Late triassic footprint assemblage in China and the first discovery of diagnostic triassic sauropodomorph tracks in this region. the tracks share a number of features in common with the ichnogenera Eosauropus(Late triassic) and Liujianpus(Early Jurassic). the neighboring Bingtu tracksite is stratigraphically younger(Shaximiao Format.on, Middle Jurassic) and preserves small tridactyl theropod tracks that represent the first.occurrence of the ichnotaxon Carmelopodus in China and Asia. While these tracks are morphologically comparable to t.ose from the Middle Jurassic type locality in North America, the specimens from China show the proximal margin of the digit IV impression in a more cranial posit.on, which may indicate a trackmaker with a relatively short metatarsal IV. In addit.on to the skeletal record, the Carmelopodus footprints document the presence of small theropods in the dinosaur fauna of the Middle Jurassic Shaximiao Format.on.

tetragonal zirconia polycrystals containing 3 mol% yttria (3Y-tZP), which show Superplasticity at high temperatures, were irradiated using 130 MeV Zr+" ions in the tANDEM accelerator facility at tokai Research Establishment, JAERI. the irradiat.on induced atomic displacement damage was analyzed by tRIM code. Changes in the mechanical properties and fracture behavior caused by the ion irradiat.on and the effects of subsequent annealing were studied. the distribut.on of micro-indentat.on depth as a funct.on of the indentat.on posit.on from the irradiated surface to the specimen interior was also examined. the occurrence of compressive residual stresses and increases in hardness and fracture toughness were found in the as-irradiated surface region of the specimen. the subsequent annealing revealed that these quantities were decreased gradually with raising the annealing temperature. Probable causes of the generat.on of the residual stress and the changes in mechanical properties and fracture mode due to the irradiat.on are discussed.

We have developed a set.of chemometric met.ods to address t.o critical issues in quality cont.ol of a precious tradit.onal Chinese medicine （tCM）, Dong＇e Ejiao （DEE J）. Based on near infrared （NIR） spectra of multiple samples, the genuine manufacturer of DEE J, e.g. Dong＇e Ejiao Co., Ltd., was accurately identified among 21 suppliers by the fingerprint met.od using Hotelling t2, distance to Model X （DModX）, and similarity match value （SMV） as dis- criminate criteria. Soft independent modeling of the class analogy algorithm led to a misjudgment rat.o of 6.2%, suggesting that the fingerprint met.od is more suitable for manufacturer identificat.on. For another important feature related to clinical efficacy of DEE J, storage time, the partial least squares-discriminant analysis （PLS-DA） met.od was applied with a satisfactory misjudgment rat.o （15.6%） and individual predict.on error around 1 year. our results demonstrate that NIR spectra comprehensively reflect the essential quality informat.on of DEE J, and with the aid of proper chemometric algorithms, it is able to identify genuine manufacturer and determine accurate storage time. the overall results indicate the promising potential of NIR spect.oscopy as an effective quality cont.ol t.ol for DEEJ and other precious tCM products.
