Changes in soil properties and microbial communities regulated rhizosphere protistan assemblages. • Bacterial community was more sensitive to soil amendments than protists and fungi. • Soil amendments trigger the role of specific protistan taxa Cercozoa on microbial interactions. Understanding the responses of different rhizosphere microbial lineages to soil amendments during in situ remediation of Cd-contaminated soil is of great importance in the assessment of the restoration and crop health. Here, we evaluated the effects of lime (LM), biochar (BC), pig manure (PM), and a commercial Mg-Ca-Si conditioner (CMC) on the rice rhizosphere soil physicochemical properties and community assembly of bacteria, fungi, and protists in a six-year consecutive application of soil amendments field trial. Our results indicated that among the four amendments, the BC and CMC had the best efficiency in increasing soil pH, which were 5.2% and 16.2%, respectively. Despite the differences in soil Cd concentrations is not noticeable, all the soil amendment treatments significantly decreased the proportion of available Cd in total Cd compared to the control. Soil amendments significantly altered the diversity of bacterial community, while they had no effect on fungal and protistan communities. Linear discriminant analysis effect size (LEfSe) showed that the bacteria was more sensitive to soil amendment-induced changes. For protists, treatments with LM and BC changed the groups of protistan consumers, while treatments with PM and CMC significantly increased the relative abundances of protistan phototrophs. Co-occurrence network analysis revealed that soil amendments increased microbial network complexity and triggered the role of protists, especially for the predatory protists Cercozoa, on microbial trophic interactions. Further variation partitioning analysis revealed that edaphic properties, bacterial and fungal communities compositions together explained the 77% of the total variation i

灸法既能温阳补虚、益气固表以调节气虚质和阳虚质人群的体质,又能祛湿散热以调节湿热质和痰湿质人群的体质,还能温通经络、调和阴阳以提高人体正气。故而,灸法能改善人乳头瘤病毒(human papillomavirus,HPV)易感人群的体质,提高HPV易感人群的正气,降低HPV持续感染的概率。但关于灸法防治HPV的资料较少,尚存在一定的局限性:(1)中医典籍中并无明确记载与宫颈HPV感染相一致的病名,只能参照与此相近的疾病展开研究分析,结论可能存在一定程度的偏颇;(2)关于灸法防治宫颈HPV病毒感染的研究缺乏数据支持,且西医理论基础薄弱;(3)关于灸法防治宫颈HPV病毒感染的相关临床试验较少,且样本量不足。今后,还需要大量的临床试验及基础实验研究来进一步佐证,以期为中医防治宫颈HPV感染奠定基础。

实体消歧和谓词匹配是中文知识库问答系统(CKBQA)中的两个核心任务。针对开放域知识库中实体和谓词数量巨大,且中文问句与知识库知识在表现形式上存在差异的问题,提出一种基于特征增强的BERT的流水线式问答系统(BERT-CKBQA),改进了上述两个子任务。采用BERT-CRF模型识别问句中提及的实体,得到候选实体集合。将问题和拼接谓词特征的候选实体输入BERT-CNN模型进行实体消歧。根据实体生成候选谓词集合,提出通过注意力机制引入答案实体谓词特征的BERT-BiLSTM-CNN模型进行谓词匹配。结合实体和谓词的得分确定查询路径来检索最终答案。该方法设计了一个中文简单问题的开放域知识库问答系统,引入预训练模型与谓词特征增强子任务特征以提升其性能,并在NLPCC-ICCPOL-2016KBQA数据集上取得了88.75%的平均F1值,提高了系统的回答准确率。

为合理描述分析脆性煤体在三向应力状态下的应力-应变关系,对煤样进行三轴压缩试验。以已发生损伤破坏的微元体数目与总微元体数目之比表征损伤变量,在基于损伤力学理论和煤样内部微元强度服从Weibull分布的基础上,引入Mogi-Coulomb强度准则表征煤样微元强度随机分布的分布变量,建立煤样三维统计损伤本构关系,并分析其适用性。研究结果表明:(1)围压对煤样力学性质影响显著,煤样强度和弹性模量随围压的增高而增大,煤样破坏后的裂隙网络分形维数随围压的增高而减小,损伤程度降低;(2)分析数学简化算法求解模型参数的局限性,采用遗传算法对模型参数进行求解,参数m,Fo,Cn分别反映煤样的脆性程度、平均强度、残余强度;(3)根据本构关系对煤样试验应力-应变曲线进行拟合验证,理论曲线与试验曲线的拟合度均值为94.74%,表明本文所建立的本构模型可用于描述煤样的三维应力-应变关系,能够反映脆性煤体的变形特性。

Searching for a Schizophrenia Susceptibility Gene in the 22q11 Region

Biomedical and Environmental Sciences 2005年第1期18卷 31-35页

作者： LINXIE GUI-ZHIJU SHU-ZHENGLIU JIE-PINGSHI YA-qinyu JUNWEI ResearchCenterforGenomicMedicine＆MHRadiobiologyResearchUnit SchoolofPublicHealthJilinUniversityChangchun130021JilinChina PostdoctoralFellowofInstituteofGeneticsandCytology SchooloftheSciencesNortheastNormalUniversityChina SchizophreniaAssociationofGreatBritain InstituteofBiologicalPsychiatryBangorUK

To investigate a genetic association for schizophrenia within chromosome 22q11 in a Chinese han population. Methods The PCR-based restriction fragment length polymorphism (PCR-RFLP) analysis was used to detect three single nucleotide polymorphisms (SNPs), rs165655 (A/G base change) and rs165815 (C/T base change) present in the ARVCF (armadillo repeat gene deletion in velocardiofacial syndrome) locus, and rs756656 (A/C base change) in the LOC128979 (expressed sequence tags, EST) locus, among 100 Chinese family trios consisting of fathers, mothers and affected offspring with schizophrenia. Genotype data were analyzed by using linkage disequilibrium (LD) methods including haplotype relative risk (HRR) analysis, transmission disequilibrium test (TDT) and haplotype transmission analysis. Results The genotype frequency distributions of three SNPs were all in Hardy-Weinberg equilibrium (P>0.05). Both the HRR and the TDT analysis showed that rs165815 was associated with schizophrenia (χ2=6.447, df=1, P=0.011 and χ2=6.313, df=1, P=0.012, respectively), whereas the other two SNPs did not show any allelic association. The haplotype transmission analysis showed a biased transmission for the rs165655-rs165815 haplotype system (χ2=17.224, df=3, P=0.0006) and for the rs756656- rs165655-rs165815 hapoltype system (χ2=20.965, df=7, P=0.0038). Conclusion Either the ARVCF gene itself or a nearby locus may confer susceptibility to schizophrenia in a Chinese han population.
