1急性下呼吸道感染儿童的维生素D摄入显示文摘目的明确维生素D(Vit D)摄入是否与儿童急性下呼吸道感染(ALRI)相关。方法比较因毛细支气管炎或肺炎入院的5岁以下儿童和非配对、无呼吸道感染的同龄对照组儿童之间Vit D摄入的差别。197例儿童的看护人完成了问卷调查,内容包括人口统计变量、ALRI危险因素和饮食。评估ALRI与Vit D摄入及其他危险因素的相关性。结果 ALRI组儿童的平均Vit D摄入为每日48 IU/kg,对照组为每日60 IU/kg。当控制年龄、民族、社会经济地位、北部地区居住、母乳喂养、免疫接种和接触吸烟等因素时,Vit D每日摄入<80 IU/kg的儿童患ALRI的可能性比每日摄入≥80 IU/kg的儿童高4倍(OR=4.9;95%CI:1.5~16.4)。结论为了避免罹患ALRI等疾病,5岁以下儿童可能需要摄入比现在推荐量更高的Vit D剂量。因毛细支气管炎和肺炎是年幼儿童住院的最常见原因,增加Vit D的补充可能有重要的公共卫生保健意义。Karen S Leis J Dayre McNally Matthew R Montgomery Koravangattu Sankaran Chandima Karunanayake Alan M Rosenberg 马丽亚(译) 2012中国当代儿科杂志2012,14,1:25
2Thrips: Pests of Concern to China and the United States显示文摘Thrips are among the most important agricultural pests globally because of the damage inflicted by their oviposition, feeding, and ability to transmit plant viruses. Because of their invasiveness, a number of pest species are common to both China and the United States and present significant challenges to growers of a wide range of crops in both countries. Among the pest thrips common to both countries are four of the major global thrips pests, Frankliniella occidentalis (Pergande), Scirtothrips dorsalis Hood, Thrips palmi Karny, and Thrips tabaci Lindeman. This review addresses characteristics that enable thrips to be such damaging pests and how biological attributes of thrips create challenges for their management. Despite these challenges, a number of successful management tactics have been developed for various cropping systems. We discuss some of these tactics that have been developed, including the use of cultural controls, biological controls, and judicious use of insecticides that do not disrupt overall pest management programs. The exchange of this type of information will help to facilitate management of pest thrips, especially in regions where species have recently invaded. A prime example is F. occidentalis, the western flower thrips, which is native to the United States, but has recently invaded China. Therefore, management tactics developed in the United States can be adapted to China. Because further success in management of thrips requires a thorough understanding of thrips ecology, we discuss areas of future research and emphasize the importance of collaboration among different countries to enhance our overall understanding of the biology and ecology of thrips and to improve management programs for these widespread pests.Smart R Reitz GAO Yu-lin LEI Zhong-ren 2011Agricultural Sciences in China2011,10,6:18
3Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11
4The mRNA Expression Profiles of Five Heat Shock Protein Genes from Frankliniella occidentalis at Different Stages and Their Responses to Temperatures and Insecticides显示文摘The western flower thrips, Frankliniella occidentalis(Pergande) is a highly invasive pest that is able to exploit many crops across a wide range of environmental conditions. Five full-length cDNAs of heat shock protein(HSP) genes(Fo-HSP90, Fo-HSP70, Fo-HSP60, Fo-HSP40 and Fo-HSP28.9) were cloned from F. occidentalis, and their expression profiles were investigated under conditions of thermal stress and insecticide exposure, and at different stages during development, using real-time quantitative PCR. All five gene sequences showed high similarity to homologs in other species, indicating the conserved function of this gene family. HSP60 represents an informative phylogenetic marker at the ordinal taxonomic level within Insecta, but HSP90, which has two homologous copies in Hymenoptera, was not informative. T he expression of Fo-HSPs under thermal stress suggests that Fo-HSP90, Fo-HSP70, and Fo-HSP28.9 are inducible by both cold and heat stress, Fo-HSP40 is only heat-inducible, and Fo-HSP60 is thermally insensitive. There were two patterns of cold induction of Fo-HSPs: one is from 0 to 4°C and the other is around-8°C. All five Fo-HSPs genes were induced by exposure to sublethal concentrations of the insecticide avermectin. The expression of the five Fo-HSPs during different developmental stages suggests that they all play a role in development of F. occidentalis.WANG Hai-hong Stuart R Reitz WANG Li-xia WANG Shuai-yu LI Xue LEI Zhong-ren 2014Journal of Integrative Agriculture2014,13,10:10
5Lithological Discrimination of the Mafic-Ultramafic Complex, Huitongshan, Beishan, China: Using ASTER Data显示文摘The Beishan area has more than seventy mafic-ultramafic complexes sparsely distributed in the area and is of a big potential in mineral resources related to mafic-ultramafic intrusions. Many mafic-ultramafic intrusions which are mostly in small sizes have been omitted by previous works. This research takes Huitongshan as the study area, which is a major district for mafic-ultramafic occurrences in Beishan. Advanced spaceborne thermal emission and reflection radiometer(ASTER) data have been processed and interpreted for mapping the mafic-ultramafic complex. ASTER data were processed by different techniques that were selected based on image reflectance and laboratory emissivity spectra. The visible near-infrared(VNIR) and short wave infrared(SWIR) data were transformed using band ratios and minimum noise fraction(MNF), while the thermal infrared(TIR) data were processed using mafic index(MI) and principal components analysis(PCA). ASTER band ratios(6/8, 5/4, 2/1) in RGB image and MNF(1, 2, 4) in RGB image were powerful in distinguishing the subtle differences between the various rock units. PCA applied to all five bands of ASTER TIR imagery highlighted marked differences among the mafic rock units and was more effective than the MI in differentiating mafic-ultramafic rocks. Our results were consistent with information derived from local geological maps. Based on the remote sensing results and field inspection, eleven gabbroic intrusions and a pyroxenite occurrence were recognized for the first time. A new geologic map of the Huitongshan area was created by integrating the results of remote sensing, previous geological maps and field inspection. It is concluded that the workflow of ASTER image processing, interpretation and ground inspection has great potential for mafic-ultramafic rocks identifying and relevant mineral targeting in the sparsely vegetated arid region of northwestern China.Lei Liu Jun Zhou Dong Jiang Dafang Zhuang Lamin R Mansaray 2014Journal of Earth Science2014,25,3:8

8Pathological and biochemical alterations of astrocytes in ovariectomized rats injected with D-galactose:A potential contribution to Alzheimer's disease processes显示文摘Astrocytes are implicated in the pathological changes of Alzheimer's disease. Our previous studies have demonstrated that estrogen deprivation and oxidative stress act synergistically to accelerate the progress of Alzheimer's disease. Long-term D-galactose injection combined with ovariectomy may serve as a rodent model for Alzheimer's disease. To address the potential contribution of astroglia to the Alzheimer's disease pathogenesis, we investigated pathological and biochemical alterations of astrocytes under this animal model. Ovadectomized rats injected with D-galactose for 2 weeks showed extensive localization of glial fibrillary acidic protein immunoreactive astrocytes and slightly elevated glutathione levels in the hippocampus without significant impairments in the water maze test and deficits of the cholinergic analyses, compared to the saline-injected rats. Ovariectomized rats injected with D-galactose for 6 weeks, however, exhibited degeneration of astrocytes and decreased glutathione levels in the hippocampus, accompanied with severe dysfunction of behavioral test and deficiency of cholinergic terminals. Electron microscopy further confirmed the pathological changes of astrocytes, especially in the aggregated area of synapse and brain microvessels. Consistent with degeneration of perivascular astrocytic endfeet, analysis of the horseradish peroxidase demonstrated an impairment of the blood-brain barrier permeability. These findings indicate that biochemical and pathological alterations of astrocytes may partially contribute to exacerbating neuronal deficits in the course of Alzheimer's disease. Restoring neuroprotective potential of astrocytes may be a useful therapeutic target for Alzheimer's disease and other neurodegenerative diseases.Hua, X. D. Lei, M. Ding, H. Han, Q. Y. Hu, G.

10Research on Isolation and Clone of Embryonic Stem Cell-Like in Bovine显示文摘Bovine embryonic stem cell would be invaluable for researching the aspect of animal cloning, production transgenic animal and discussion of gene function in vitro. With the object of establishing an effective culture system for isolation and clone of bovine pluripotent stem cell, we cultured bovine embryos and mouse embryos including morula blastula and hatached blastula and obtained animal ICM on Primary marine embryonic fibroblast (Primary murine embryonic fibroblast, PMEF) feeder layer with tissue medium(DMEM supplemented with 15ml/100ml NBS ,0.1μmol/L Na2SeO3, 0. 1mmol/L β-mercaptoethanol, 1 000ng/ml LIF,10 ng/ml IGF, 1mmol/L necessary amino acid and 1mmol/L L-glutamine), then, we obtained mouse ICM and bovine ICM. Moreover, we isolated and cloned the 6 passage bovine ES like cells(12 cell lines) and 9 passage marine ES like cells (52 cell lines) deriving from bovine ICM and murine ICM respectively on the feeder layer of PMEF by disaggregating ICM and ES cell clones of bovine and murine into smaller clumps through digesting with 0. 125g/100ml trypsin and 0.02g/100ml EDTA and scattering with a glass needle. The pluripotency of both murine and bovine ES like cells was identified with morphological character, histochemistry identification, karyotype analysis and differentiation of ES cells in vitro or in vivo. This result showed that bovine embryonic stem cell and murine embryonic stem cell had developmental pluripotency.AN Li-long, YANG Qi, XIAO Mei, FENG Xiu-Liang, YANG Chun-rong, LEI An-min, GAO Zhi-min, DOU Zhong-ying and QIU Huai( Agriculture College of Zhanjiang Ocean University, Zhanjiang 524008 , P.

11Contribution of genotype and ethnicity to bone mineral density variation in Caucasians and Chinese: a test for five candidate genes for bone mass显示文摘Background Ethnicity is shown to be one of important factors affacting bone mineral density (BMD). The present study was performed to compare the association of six markers for five candidate genes with BMD variation in two populations of different ethnicity, Caucasian and Chinese, and the contribution of genotype and ethnicity to this variation in the populations.Methods The studied restriction fragment length polymorphisms were Bsa H Ⅰ of the calcium-sensing receptor gene, Sac Ⅰ of the α2HS-glycoprotein (AHSG) gene, Pvu Ⅱ and Xba Ⅰ of the oestrogen receptor α gene, Apa Ⅰ of the vitamin D receptor (VDR) gene and BstB Ⅰ of the parathyroid hormone gene. The association of these markers with BMD was analysed by one-way and two-way ANOVA with adjustment for covariates. Results Two polymorphisms, AHSG- Sac Ⅰ and VDR- Apa Ⅰ, showed no association with BMD, while the others were associated with BMD variation at some skeletal sites in either males or females. The polymorphisms indicated clear distinctions between the associations depending on ethnicity, gender and skeletal site. Similar patterns were observed in their contribution to the total population BMD variation. Ethnicity appears to have a larger effect on the total population BMD variation in females than in males. It may account, on the average, for about 2% total population BMD variation at the spine of females and about 1% at the hip of males and females. Conclusion The results of the present study suggest that significant interethnic differentiation at some loci may contribute to the significant interethnic difference in BMD. However, this contribution apparently is not large.Volodymyr Dvornyk LIU Peng-yuan LONG Ji-rong ZHANG Yuan-yuan LEI Shu-feng Robert R Recker DENG Hong-wen 2005Chinese Medical Journal2005,,15:2
