为探究不同微生物制剂对大口黑鲈生长、形体指标及肠道组织结构的影响,在商业配合饲料中添加不同浓度的丁酸梭菌[0(A组,CK)、0.25%(B组)、0.5%(C组)、1%(D组)丁酸梭菌(5×10^(8) cfu·g^(-1))]、0.2%酵母产品(E组)及两者的混合物(0.25%丁酸梭菌+0.2%酵母产品,F组)进行两阶段共17周的养殖试验。结果表明:第一阶段(14周)试验组中,除添加0.2%酵母产品(E组)外,其余均较对照显著提升了大口黑鲈的生长性能,其中添加0.5%丁酸梭菌效果最优;第二阶段(17周)试验组间(A、C和F组),0.5%丁酸梭菌(C组)和0.25%丁酸梭菌+0.2%酵母产品(F组)的末均重及末体长较对照A组均显著增加;肥满度、脏体比指数、肠绒毛长度及肌层厚度三组间无显著差异,但与对照(A组)相比,添加0.5%丁酸梭菌(C组)的各指标有增高趋势,添加0.25%丁酸梭菌+0.2%酵母产品(F组)的各指标有降低趋势。研究表明,在本试验条件下,商业配合饲料中添加0.5%丁酸梭菌对大口黑鲈生长及肠道健康改善的效果最佳。

自毒作用是植物连作障碍形成的主要原因之一,严重影响植物生长和粮食生产。前期研究结果表明,土壤微生物多样性下降、土传病害加重是枸杞园连作障碍形成的重要原因,但枸杞残体的自毒作用及其物质基础目前仍不明确。为探讨自毒物质的主要来源,本研究对比分析了枸杞(Lycium barbarum L.)叶、茎、根等组织浸提液对枸杞幼苗生长的影响。浓度梯度试验结果表明,叶片浸提液的抑制效应高于根、老根皮及茎浸提液。向无枸杞种植历史的农田土壤中添加枸杞叶片干粉能够显著抑制枸杞幼苗生长及叶片光合作用,证实了枸杞叶片具有自毒作用。联合UPLC-QTOF-MS和GC-TOF-MS技术对生长季末期枸杞叶片进行代谢组分析,共鉴定出有机酸112种、醇类41种、氨基酸37种、醛酮类28种和糖类48种。对其中24种有机酸及衍生物的分析发现,20种有机物能够不同程度抑制枸杞幼苗初生根生长。其中水杨酸、邻苯二甲酸、对羟基苯甲酸和香豆素在浓度低至10μmol/L时仍具显著抑制效应。UPLC结果进一步显示,长期连作导致枸杞园土壤香豆素、水杨酸、苯甲酸、阿魏酸和香豆酸积累。此外,土壤总酚酸含量也随种植年限增加显著增加。这些结果表明土壤中枸杞叶片酚酸能够在长期连作下积累并诱发自毒作用,这为进一步探索枸杞连作障碍形成机制提供了研究基础。

Abstract The electrochemical properties of two basic violets （methyl violet and ethyl violet） at the MWNTs/Nafion modified glassy carbon electrode were investigated. The redox of the basic violets is two-electron and two-proton process, and methyl violet presents stronger electron transfer capacity than ethyl violet. Meanwhile, the inclusion constants of the two basic violets with five CDs were determined by differential pulse voltammetry （DPV）. The two basic violets and CDs can form 1：1 complexes, The inclusion capacities of the two basic violets follow the same order： CM-β-CD 〉 HP-β-CD 〉 TM-β-CD 〉 DM-β- CD 〉 β-CD. ？2009 Yu jing Guo.

目的探讨收缩压变异性(SBPV)和心率变异性(HRV)对维持性血液透析(MHD)患者主要不良心血管事件(MACE)发生风险的预测价值。方法纳入2017年3月—2018年3月在宜昌市中心人民医院肾病内科血液净化中心接受规律治疗的MHD患者120例,根据是否发生MACE分为MACE组(n=59)与无MACE组(n=61)。在患者行血液透析前佩戴Holter,收集24 h心电活动信息,计算均值(MEAN)、RR间期总体标准差(SDNN)、RR间期平均值的标准差(SDANN)和相邻RR间期差值的均方根(r-MSSD)。采用自动血压监测系统记录24 h血压变化,计算白昼收缩压变异性(dSBPV)、夜间收缩压变异性(nSBPV)和24 h收缩压变异性(24 h SBPV)。Logistic回归分析MHD患者MACE发生的危险因素。调整混杂因素后,采用Cox比例风险模型回归分析24 h SBPV和SDNN与MHD患者MACE发生的关系。绘制受试者工作特征(ROC)曲线,计算曲线下面积(AUC)、灵敏度、特异度,分析SDNN和收缩压变异性单独及联合对维持性MHD患者发生MACE的预测价值。根据SDNN和24 h SBPV水平将患者分成3组,绘制Kaplan-Meier生存曲线评价不同SDNN和收缩压变异性的MHD患者MACE发生情况。结果与无MACE组相比,MACE组年龄较大,24 h SBPV、dSBPV、nSBPV较高,SDNN、SDANN较低,差异具有统计学意义(P<0.05)。Logistic回归分析显示,年龄、Kt/V、24 h SBPV、dSBPV、nSBPV、SDNN、SDANN是MHD患者MACE发生的独立危险因素(P<0.05)。调整混杂因素后,多因素COX比例风险模型回归分析,24 h SBPV为MHD患者发生MACE的危险因素,而SDNN为MHD患者发生MACE的保护性因素(P<0.05)。SDNN与收缩压变异性联合预测MHD患者发生MACE的AUC为0.879,预测效能高于单项检测(P<0.05)。组1随访期间累积MACE发生率显著低于组2和组3(19.15%vs 65.12%vs 73.33%,P<0.001)。结论 MHD不良预后患者中24 h SBPV升高,SDNN降低,24 h SBPV和SDNN单独预测MACE的具体价值尚可,两者联合预测效果更佳,可为临床上及早识别及干预MHD患者MACE发生提供参考依据。

High yield in rice mainly depends on large grain weight, ideal plant architecture and proper flowering time adapting to various geographic regions. To help achieve higher yield, phenotype variations of heading date（HD）, plant architecture and grain shape in a panel of 416 rice accessions were investigated in this study. A total of 143 markers including 100 simple sequence repeat（SSR） markers and 43 gene-tagged markers were employed in association mapping to detect quantitative trait loci（QTL） responsible for these variations. Among the 7 subpopulations, POP5 in japonica group showed the largest values of HD and grain width（GW）, but the smallest values of grain length（GL） and grain length to width ratio（GLW）. Among the six indica groups, POP7 had the largest values of HD, GL, GLW, and 1 000-grain weight（TGW）. A total of 27 QTLs were detected underlying these phenotypic variations in single year, while 12 of them could be detected in 2006 and 2007. GS3 marker was closely associated with GL, GW and GLW, and widely distributed in different groups. The starch synthesis related gene markers, SSI, SSIIa, SBE1, AGPL4, and ISA1, were linked to plant height（PH）, panicle length（PL）, flag leaf length（FLL）, GW, and GLW. The SSR markers, RM267, RM340 and RM346, were linked to at least two traits. Therefore, these new markers will probably be used to improve rice grain yield or plant architecture when performing marker-assisted selection of proper alleles.

Phospholipids are a major kind of lipids in rice grains and have fundamental nutritional andfunctional benefits to the plant. Their lyso forms （lysophospholipids, LPLs） often form inclusion complexeswith amylose or independently influence the physicochemical and functional properties of rice ***, the genetic basis for LPL synthesis in rice endosperm is largely unknown. Here, we performeda preliminary association test of 13 LPL compositions among 20 rice accessions, and identified 22putative main-effect quantitative trait loci responsible for all LPLs except for LPC14：0 and LPE14：0. Fivederived cleaved amplified polymorphic sequences and one insertion/deletion marker for threeLPL-synthesis-related candidate genes were developed. Association analysis revealed two markerssignificantly associated with starch LPL traits. These results provide an insight into the genetic basis ofphospholipid biosynthesis in rice and may contribute to the rice quality breeding programs usingfunctional markers.

Horticulture is an important part of agricultural planting and production, which is of great significance for enriching human nutrition and beautifying and transforming the human living environment. At present, the area of horticultural crops in China is about 40 million ha, accounting for about onefourth of the national crop planting area, while the production of primary agricultural products is 1 billion tons, and the output value accounts for more than half of the total output value of the planting industry.
