With For a large number of incomplete fault data,the traditional artificial intelligence methods based cannot effectively and timely analysis or can not be accurately diagnosed or misdiagnosed because of the ill-conditioned problem caused by inefficient discretization approaches.A method based on rough set theory integrated with improved artificial fish-swarm algorithm (IAFSA) was presented in this paper for fault diagnosis of ***,the values of dissolved gas-in-oil analysis (DGA) were taken as conditional attributes and the type faults were taken as decision *** relations between fault and symptom were connected and decision table was established. the improved artificial fish-swarm algorithm is used to discrete continuous attribute;then,using the rough set theory to reduce the decision *** simplified decision rules were got,which greatly simplifies the difficulty of diagnosis The experimental results indicate that the method has increased the diagnosis accuracy compared with traditional algorithm.

乳酸菌的抑菌活性决定了其在食品、医药等领域的应用效果。为通过不同乳酸菌的共培养提高其抑菌活性,采用双层琼脂扩散法以大肠杆菌K88为指示菌测定干酪乳杆菌NA-2及其添加鼠李糖乳杆菌LGG共培养后的抑菌活性,首先通过单因素试验对2株菌的共培养体系包括接种比例、培养温度、时间、通气方式、碳氮源、pH等条件进行优化,然后应用实时荧光定量PCR和高效液相色谱法分别对共培养条件优化前后的活菌数和乳酸含量进行测定。结果表明,干酪乳杆菌NA-2与鼠李糖乳杆菌LGG共培养后抑菌活性显著增加;与干酪乳杆菌NA-2单菌株培养和优化前共培养体系相比,优化后共培养体系的抑菌活性分别提高20.7%和11.0%,乳酸产量分别提高15.2%和7.3%;干酪乳杆菌NA-2和鼠李糖乳杆菌LGG的总活菌数由优化前共培养体系中的2.74×10^(8) CFU·mL^(-1)下降到优化后的1.57×10^(8) CFU·mL^(-1),但干酪乳杆菌NA-2的比例从7.0%提高到65.6%。以上研究结果为乳酸菌共培养体系的深入研究和应用提供数据支撑。

Background: People are paying more attention to the healthy and balanced diet with the improvement of their living standards. Milk fatty acids(FAs) have been reported that they were related to some atherosclerosis and coronary heart diseases in human. In our previous genome-wide association study(GWAS) on milk FAs in dairy cattle, 83 genomewide significant single nucleotide polymorphisms(SNPs) were detected. Among them, two SNPs, ARS-BFGL-NGS-109493 and BTA-56389-no-rs associated with C18 index(P = 0.0459), were located in the upstream of 1-acylglycerol-3-phosphate O-acyltransferase 3(AGPAT3) gene. AGPAT3 is involved in glycerol-lipid, glycerol-phospholipid metabolism and phospholipase D signaling pathways. Hence, it was inferred as a candidate gene for milk FAs. The aim of this study was to further confirm the genetic effects of the AGPAT3 gene on milk FA traits in dairy ***: Through re-sequencing the complete coding region, and 3000 bp of 5′ and 3′ regulatory regions of the AGPA T3 gene, a total of 17 SNPs were identified, including four in 5′ regulatory region, one in 5′ untranslated region(UTR),three in introns, one in 3′ UTR, and eight in 3′ regulatory region. By the linkage disequilibrium(LD) analysis with Haploview4.1 software, two haplotype blocks were observed that were formed by four and 12 identified SNPs,respectively. Using SAS9.2, we performed single locus-based and haplotype-based association analysis on 24 milk FAs in 1065 Chinese Holstein cows, and discovered that all the SNPs and the haplotype blocks were significantly associated with C6:0, C8:0 and C10:0(P A, g.146704373 A > G, g.146704618 A > G and g.146704699 G > A) changed the transcription factor binding sites(TFBSs) for transcription factors SMARCA3, REX1, VMYB, BRACH, NKX26, ZBED4, SP1, USF1, ARNT and FOXA1. Out of them, two SNPs were validated to impact transcriptional ac

库车山前深部巨厚盐膏层地质特征复杂,地层压力变化大,预测难度高。盐膏层钻井过程中,钻井液性能恶化,喷、漏、卡等复杂事故频发,严重影响安全快速钻井。针对以上难点,DN2-29H井以高密度饱和盐水钻井液体系为基础,引入新型材料稀释稳定剂,并优化了钻井液维护措施。实践证明,引入新型稀释稳定剂后,体系在盐膏层钻进过程中性能稳定,复杂工况明显降低,工期缩短,起下钻顺畅,电测、下套管均一次成功。本井经验对钻遇巨厚盐膏层具有重要的参考意义。

目的探讨颈动脉内中膜厚度(cIMT)联合血清半乳凝集素-3(Gal-3)和正五聚蛋白3(PTX3)对银屑病患者并发心血管疾病(CVD)的诊断价值。方法将38例银屑病伴CVD患者纳入CVD组,将51例单纯银屑病患者纳入银屑病组,另选取同期60例健康体检者纳入对照组。收集各组临床资料,使用颈动脉彩超检测cIMT,采用酶联免疫吸附试验检测血清Gal-3、PTX3和炎性指标[超敏C反应蛋白(hs-CRP)、降钙素原(PCT)、肿瘤坏死因子-α(TNF-α)]水平。采用多因素Logistic回归分析明确银屑病患者并发CVD的影响因素,绘制受试者工作特征(ROC)曲线,评估血清Gal-3、PTX3和cIMT对CVD的诊断价值。结果CVD组、银屑病组cIMT大于对照组,且CVD组大于银屑病组,差异有统计学意义(P<0.05);CVD组和银屑病组血清Gal-3、PTX3、hs-CRP、PCT、TNF-α水平高于对照组,且CVD组高于银屑病组,差异有统计学意义(P<0.05);CVD组银屑病皮损面积和严重程度指数(PASI)评分高于银屑病组,差异有统计学意义(P<0.05)。Pearson积矩相关分析结果显示,cIMT、Gal-3、PTX3均分别与hs-CRP、PCT、TNF-α呈正相关(P<0.05)。多因素Logistic回归分析结果显示,PASI评分、cIMT、Gal-3、PTX3、hs-CRP、TNF-α均为银屑病患者并发CVD的独立影响因素(OR=1.250、1.451、1.432、1.365、1.413、1.465,P<0.05)。基于cIMT和血清Gal-3、PTX3联合构建的诊断模型对银屑病患者并发CVD的诊断价值高于单独诊断,曲线下面积为0.922,灵敏度、特异度分别为0.91、0.85。结论cIMT、血清Gal-3、血清PTX3是银屑病患者并发CVD的独立影响因素,三者联用对银屑病患者并发CVD具有较高的诊断价值。
