Journal of Integrative Agriculture 2012年第5期11卷 752-759页

Feature optimization is important to agricultural text mining. Usually, the vector space model is used to represent text documents. However, this basic approach still suffers from two drawbacks： thecurse of dimension and the lack of semantic information. In this paper, a novel ontology-based feature optimization method for agricultural text was proposed. First, terms of vector space model were mapped into concepts of agricultural ontology, which concept frequency weights are computed statistically by term frequency weights; second, weights of concept similarity were assigned to the concept features according to the structure of the agricultural ontology. By combining feature frequency weights and feature similarity weights based on the agricultural ontology, the dimensionality of feature space can be reduced drastically. Moreover, the semantic information can be incorporated into this method. The results showed that this method yields a significant improvement on agricultural text clustering by the feature optimization.

目的探讨半胱氨酸蛋白酶抑制剂C(Cys C)与糖尿病肾病(DKD)的相关性。方法收集2019年1月至12月陕西省人民医院内分泌科住院的122例2型糖尿病(T2DM)患者的临床资料,按尿白蛋白与肌酐比值(UACR)分为单纯糖尿病(DM)组(UACR<30 mg/g,89例)、DKD组(UACR≥30 mg/g,33例)。比较两组临床资料,采用logistic回归分析T2DM患者发生DKD的危险因素,绘制受试者操作特征(ROC)曲线评价Cys C对DKD的预测价值。结果DKD组收缩压、碱性磷酸酶、总蛋白、球蛋白、血清肌酐、尿微量白蛋白、尿α_(1)微球蛋白、UACR、Cys C均高于单纯DM组,病程长于单纯DM组(P<0.05)。logistic回归分析显示,Cys C是DKD的危险因素(OR=28.369,95%CI:1.208~666.129,P=0.038)。ROC曲线分析显示,Cys C预测DKD的曲线下面积为0.757(P<0.05)。结论Cys C与T2DM合并DKD密切相关,检测Cys C可用于评估DKD病情进展。

Cytochrome P450 and UDP-glucosyltransferase (UGT) as phase I and phase II metabolism enzymes, respectively, play vital roles in the breakdown of endobiotics and xenobiotics. Insects can in crease the expression of detoxificatio n enzymes to cope with the stress from xenobiotics including insecticides. However, the molecular mechanisms for insecticide detoxification in Spodoptera exigua remain elusive, and the genes conferring insecticide metabolisms in this species are less well reported. In this study, 68 P450 and 32 UGT genes were identified. Phylogenetic analysis showed gene expansions in CYP3 and CYP4 clans of P450 genes and UGT33 family of this pest. P450 and UGT genes exhibited specific tissue expression patterns. Insecticide treatments in fat body cells of S. exigua revealed that the expression levels of P450 and UGT genes were significantly influenced by challenges of abamectin, lambda-cyhalothrin, chlorantraniliprole, metaflumizone and indoxacarb. Multiple genes for detoxification were affected in expression levels after insecticide exposures. The results demonstrated that lambda-cyhalothrin, chlorantraniliprole, metaflumizone and indoxacarb induced similar responses in the expression of P450 and UGT genes in fat body cells;eight P450 genes and four UGT genes were co-up-regulated significantly, and no or only a few CYP/UGT genes were down-regulated significantly by these four insecticides. However, abamectin triggered a distinct response for P450 and UGT gene expression;more P450 and UGT genes were down-regulated by abamectin than by the other four compounds. In con elusion, P450 and UGT genes from S. exigua were identified, and different responses to abamectin suggest a different mechanism for insecticide detoxification.

【目的】探究毛竹林林下种植中药材对土壤有效态中、微量营养元素的影响,为毛竹林林下种植土壤养分资源管理及我国南方竹产区林药复合经营模式的推广提供科学参考。【方法】以广西桂林漓江源区毛竹人工林林下种植的3种中药材样地为研究对象,采用完全随机区组设计,设4个处理,即未种植中药材的毛竹林对照、林下种植黄花倒水莲(Polygala fallax)、林下种植多花黄精(Polygonatum cyrtonema)、林下种植草珊瑚(Sarcandra glabra),在种植后的第2年测定土壤基本理化性质和中、微量营养元素有效态含量,分析其相关性,明确毛竹林林下种植不同中药材土壤中、微量营养元素的变化及其主要影响因素。【结果】毛竹林林下种植中药材降低了土壤容重、总碳和有效磷含量,增加了可溶性有机碳和微生物生物量碳、氮、磷含量,种植多花黄精对上述指标的影响相对较大,除微生物生物量氮外均与对照差异显著(P0.05,下同),种植多花黄精和草珊瑚对土壤微量营养元素有效态含量的影响大于种植黄花倒水莲。相关分析结果表明,土壤中量营养元素钙、镁、硫有效态含量主要受土壤容重、有效磷及微生物生物量碳和磷影响,而微量营养元素铁、锰、铜、锌、钼有效态含量除受以上因素影响外,还与土壤pH及中量营养元素钙和镁有效态含量有关。【结论】土壤中、微量营养元素有效态含量对毛竹林林下种植不同中药材的响应存在较大差异,林下种植多花黄精对土壤养分的影响最大,种植黄花倒水莲和草珊瑚次之。在毛竹林林下种植中药材实践中需适当补充中、微量营养元素,尤其是钙镁肥的供应,且需根据种植中药材的种类采取不同施肥策略。
