| 1 | Management Strategies and Research Orientations of Forest Diseases and Pests in China显示文摘Forest diseases and pests are perceived as a growing hazard to China economy. It is a common conclusion that the actualities of forest pests in china are no effective measures to the old important pests, some secondary pests are ascending to chief pests, increasing devastation from exotic pests, frequent ecological pest eruption induced by environmental detriment and host-leading diseases to threaten the 'Western Development Project 'in China, which is the most important economical strategy to China; th... | ZHANG Xingyao LIANG Jun LU Quan YAN Donghui LUO Youqing XU Zhichun WEN Junbao1.

| 3 | Liver metabolomic characteristics in three different rat models of Yin deficiency based on ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry显示文摘OBJECTIVE:To investigate the mechanism of Yin deficiency syndrome(YDS) by analyzing the liver metabolomic characteristics of three different Yin deficiency rat models METHODS:Following the TCM etiology,for clinical features and pathological manifestations of modern medicine,three kinds of animal models of Yin deficiency were induced and replicated.Totally 48 Sprague-Dawley(SD) male rats were randomly divided into blank group,irritation induced model group,Fuzi-Ganjiang induced model group,and thyroxine-reserpine induced model group.After successful development of model,the ultraperformance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was carried out to detect metabolites in each group.The metabolites of rat liver were analyzed for the characteristics of their biomarkers.The pathway enrichment analysis and metabolic network construction were performed through various online databases including Metabolite Biology Role,Human Metabolome Database,MetaboAnalyst,and Kyoto Encyclopedia of Genes and Genomes.RESULTS:The SD rats in the experimental group showed symptoms like less weight gain,reduced diet and water intake,high body temperature,increased liver and kidney indexes,and abnormal liver and kidney tissue morphology.Moreover,the rats showed high increased levels of serum cyclic adenosine monophosphate,estradiol,alanine transaminase,and aspartate aminotransferase and decreased levels of cyclic guanosinc monophosphate and testosterone.We found four key interrelated metabolic pathways in the liver tissue metabolomics,including the biosynthesis of pantothenic acid and coenzyme A,and metabolism of alpha-linolenic acid metabolism,glycerophospholipid metabolism,and sphingolipid.CONCLUSION:The liver and kidney YDS is closely related to the biosynthesis of pantothenic acid and CoA and abnormal metabolism of α-linolenic acid,glycerophospholipid,and sphingolipid in SD rats. | HU Xingyao LIU Hongning YAN Xiaojun CHEN Zhong FU Liu LIU Ge CHEN Xuan SHANG Guangbin | 2023 | Journal of Traditional Chinese Medicine2023，43，2： | 0 |
| 4 | Detection to Pathogens of Poplar Cankers by Multiplex PCR Technique显示文摘Fungal pathogens causing poplar canker diseases are cosmopolitan in species,and have a wide range of hosts.These pathogens have diverse anamorphs and their morphology overlaps with each other;Their teleomorphs are hardly discovered in nature.Furthermore,the identification of these pathogens is usually limited by the geography,host and taxonomic knowledge.Therefore,a culture-independent method used to identify determine pathogens is expected to be developed for field diagnostics.Through amplifying,sequencing and analyzing multiplex nucleic acid templates and genetic marked target sequences,a multiplex PCR technique has been established and used to directly detect various environmental samples.In this study, four pathogen strains and environmental samples were amplified using fungal universal primers ITS1/ ITS4 and EF1-728F/EF1-986R by general PCR and multiplex PCR.The amplicons were sequenced,and then aligned in GenBank.The result showed that the multiplex PCR was able to successfully amplify the target gene and identify the pathogens from environmental samples in the condition of an annealing temperature of 55.6℃and primers final concentration of 0.2μmol·L-1.The multiplex PCR could amplify the target at the concentration level of approximately lng of genomic DNA.This method would provide a useful tool for the identification of canker pathogens by the multiplex PCR and the high-throughput DNA microarray detection of environmental samples. | Feng Xiaohui Zhang Xingyao Yan Donghui | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
