Objective To assess the risk of acute myocardial infarction (AMI) and analyze its out‐come by studying the abnormal ECG presentations in AMI patients .Methods The clinical data and ECG presentations of 381 AMI patients were retrospectively analyzed .The abnrmal ECG presentations and the mortalty were comparatively analyzed in AMI patients with multiple lead pathological Q wave ,elevated ST‐segment ,atrial fibrillation (AF) ,bundle branch conduction block ,cardiogenic shock ,and heart failure .Results T he incidence of cardiogenic shock ,heart fail‐ure and the mortality were significantly higher in patients with multiple lead pathological Q wave than in those without multiple lead pathological Q wave (58 .1% vs 21 .4% ,54 .3% vs 23.2% , 40.0% vs 6 .5% ,P<0 .05) and in patients with abnormal presentations such as elevated ST‐seg‐ment and AF than in those without abnormal ECG presentations (P<0 .05 ,P<0 .01) .Conclusion Abnormal ECG presentations ,such as multiple lead pathological Q wave ,can be used as the evi‐dence for the risk and outcome of AMI .

Objective To set up a methodology for quick finding of important leading compounds from complex plant samples. Methods A mixture fraction was determined by 1H-NMR techniques to find any evidence, further isolation of the fraction guided with this evidence was carried out. Results Based on the botanical metabonomic concept, a novel valuable sesquiterpene compound has been quickly isolated from the aerial part of Carpesium lipskyi. Conclusion The efficiency for finding of leading compounds could be improved if the isolation is based on metabonomics under the guidence of the new method of botanical mixture determination by 1H-NMR.

Objective To identify Anaplasma species circulating among livestock and rodents from Xitianmu Mountain area in Zhejiang province , Southeastern China and to analyze variations regarding to their 16S rRNA gene.Methods Samples of spleen, liver and blood were collected to extract DNAs .The 16S rRNA gene fragments of Anaplasma species were amplified by using a nested PCR and then sequenced .Ho-mology analysis was conducted by using BLAST program .The multiple sequence alignment and phylogenetic analyses comparing with the sequences of other Anaplasma species in GenBank were conducted by using MEGA 5.0 software.Results The 16S rRNA gene fragments of Anaplasma were detected in 1 cattle, 8 goats, 5 Rattus confucianus, 1 Apodemus agrarius, 1 Berylmys bowersi and 1 squirrel out of 129 animals. The natural infection rate of Anaplasma was 13.2% in animals from Xitianmu Mountain area in Zhejiang . The alignment and phylogenetic analyses indicated that there were at least four Anaplasma species prevalent in livestock and rodents from Xitianmu Mountain area , including Anaplasma phagocytophilum, Anaplasma marginale, Anaplasma centrale and Anaplasma bovis.Moreover, there was a variant that obviously differed from Anaplasmma bovis and other Anaplasma sp.in GenBank.Conclusion The Anaplasma infection was detected among livestock and rodents from Xitianmu Mountain area in Zhejiang province .A newly discovered variant in rodents was likely to be a novel species .More close attention should be paid to Anaplasma infec-tion among human in Xitianmu Mountain area .

Paeoniflorin and its derivatives are main active compounds inGui-Zhi Fu-Ling Capsule (GZFLC). In this study, molecular imprinted polymer (MIP) was prepared by sol-gel process to obtain paeoniflorin and its derivatives in GZFLC. The static adsorption capacity of MIP was measured by scatchard equation. The results showed that the maximum apparent absorbing capacity of MIP was 52.28 mg·g-1. One-step separation of paeoniflorin from 4 g methanol samples of GZFLC was 197 mg with the purity of 89.3%. It was concluded that paeoniflorin MIP can be used to separate phaoniforin and its analogues from GZFLC.
