目的:探究中国10城市6~36月龄婴幼儿膳食多样性与自报患病情况的相关性。方法:基于2019—2020年在中国10城市开展的横断面调查的数据,通过问卷收集婴幼儿的相关人口学特征、自报患病情况及膳食多样性情况,使用卡方检验、Logistic回归、负二项回归模型分析婴幼儿膳食多样性与自报患病发生率及患病次数之间的相关性。结果:我国城市婴幼儿最低膳食多样性满足率为74.6%,婴幼儿年龄越大、家庭人均月收入越高、父亲教育程度越高其最低膳食多样性满足率更高(P<0.05)。满足最低膳食多样性的婴幼儿其呼吸系统疾病(IRR=0.76,95%CI:0.58~0.98,P=0.035)以及腹泻(IRR=0.65,95%CI:0.48~0.88,P=0.006)发生的次数更低。暂未发现婴幼儿膳食多样性与各自报疾病的发生率之间存在显著相关关系。结论:中国城市6~36月龄婴幼儿膳食多样性与呼吸系统疾病以及腹泻存在一定关联。

Open Journal of Modern Neurosurgery 2023年第4期13卷 166-174页

作者： Alain Jibia Bernard Azanmene Arielle Lekane Ernestine Bikono ignatius Esenee Vincent-de-Paul Djientcheu Faculty of Medicine and Biomedical Sciences of Garoua Garoua Cameroun Neurosurgery Department Yaounde Central Hospital Yaounde Cameroun Neurosurgery Unit Essos Hospital Center Yaounde Cameroun Rheumatology Department Yaounde Central Hospital Yaounde Cameroun Neurosurgery Department Garoua Regional Hospital Garoua Cameroun

Introduction: Gout is defined as an arthritic condition resulting from the deposition of monosodium urate crystals in and/or around joints, following long-standing hyperuricemia. This may cause gouty arthritis in joints and tophi in soft tissues. Spinal gout is rare and never mentioned in our context. It can appear as acute back pain, radiculopathy, spinal cord compression, spondylodiscitis or neoplasic/infectious epiduritis. Our aim was to share our surgical experience and proceed of a Literature review. Cases Presentation: Between January and August 2022, two patients male were surgically cared, aged of 42 and 60 years old. The gout was unknown in the youngest and poorly followed in the eldest. There was no past medical history of tuberculosis or immunodeficiency in both. The early diagnosis retained was unspecific lumbar spondylodiscitis due to clinical features: Patients complained both of lower back pain with initial fever. It was of a progressive left L5S1 deficit with erectile defect and dysuria in the first case and a progressive paraplegia without sphincter disorders in the second case. We proceeded with a lumbar laminectomy with a biopsy on both patients. The spinal tophus was ligamentous in one case and arthro-ligamentous in the other. There was a progressive motor recovery from postoperative Day-2 till postoperative Month-1. A probabilistic antituberculosis treatment was promptly initiated postoperatively based on radioclinic features while waiting for histologic proof. The Polymerase Chain Reaction (PCR) of Mycobacterium tuberculosis was negative and the histology was of a chronic calcified osteitis with dense fibrosis in both. The anti-gout treatment was implemented after 15 days with blood test evidence. A rheumatologic follow-up was also initiated and adjuvant physio-therapy. The results were very satisfactory from 4 - 6 months with independent walking. Discussion Conclusion: Spinal Gout may be suggested in 40-male-old faced with any acute rachialgia

Journal of Agricultural Science and Technology(A) 2015年第3期5卷 174-182页

Maize is an important economic crop grown in Nigeria. Its production is dramatically affect by the pink stem borer--Sesamia caIamistis （Hampson, Noctuidae） and sugarcane borer--Eldana saccharina （Walker, Pyralidae） that are endemic in Southeastern Nigeria. In areas of stress, existing genotypes may marginally do well due to their inherent capabilities. Therefore, it is possible to find useful genes in such areas of stress, since such genes have been responsible for the survival of host crops over the years. Evaluation study was conducted for a range of agronomic characteristics and resistance attributes for 209 local maize collections from Southeastern Nigeria along with three improved check varieties. Field trials were conducted at three locations in a total of four environments in 2001. Highly significant genotypic variances as were noted in all the traits, are indicative of the magnitude of variation that exists among the genotypes, thus providing the opportunity of selection for desirable traits. Furthermore, four traits, namely, leaf feeding, ear damage, stalk lodging and yield were used from across the environments to construct a rank summation index （RSI）, which was used to rank the entries for resistance to stem borers. This RSI led to the identification of 11 genotypes which represents the best 5% of the 212 genotypes in resistance ability. Genotype AMA TZBR-WC1 （from International Institute of Tropical Agriculture （IITA）, Ibadan） had the best overall resistance levels, followed by genotypes SE NG-77 and SE NG-67 （from Umuahia North）, SE NG-62 （from Ikwuano）, SE NG-148 （from Ukwa West）, SE NG-106 （from Bende）, SE NG-119 （from Isiala Ngwa）, SE NG-33 （from Ikwuano） and SE NG-65 （from Umuahia North）.

目的:修订哺乳期膳食平衡指数,并评价我国十城市哺乳期妇女膳食质量,分析影响哺乳期妇女膳食质量的因素。方法:使用自设问卷和膳食频率问卷,于2019年对中国10城市863名乳母开展横断面营养健康调查。在2016年膳食平衡指数的基础上,根据2022年哺乳期妇女膳食指南调整评分标准,并评价乳母膳食质量。结果:乳母膳食摄入不平衡、不足、过量的比例分别为86.7%、85.9%、44.2%。乳母蔬菜类、水果类、奶类、大豆类及水产品类食物摄入不足,食用油和盐摄入过量严重,摄入食物多样性较低。受教育水平、收入、城市类型、体力活动水平、产后抑郁情况和是否参与孕妇学校等多种因素与乳母膳食平衡相关。结论:中国十城市乳母人群的膳食摄入不平衡主要体现为摄入不足,而摄入过量的程度相对较低。应有针对性地加强妇女产后健康教育,提高乳母膳食质量。

Identification of regulators of osteoblastogenesis that can be pharmacologically targeted is a major goal in combating osteoporosis,a common disease of the elderly population. Here, unbiased kinome RNAi screening in primary murine osteoblasts identified cyclin-dependent kinase 5(Cdk5) as a suppressor of osteoblast differentiation in both murine and human preosteoblastic cells. Cdk5 knockdown by si RNA, genetic deletion using the Cre-lox P system, or inhibition with the small molecule roscovitine enhanced osteoblastogenesis in vitro. Roscovitine treatment significantly enhanced bone mass by increasing osteoblastogenesis and improved fracture healing in mice. Mechanistically, downregulation of Cdk5 expression increased Erk phosphorylation, resulting in enhanced osteoblast-specific gene expression. Notably, simultaneous Cdk5 and Erk depletion abrogated the osteoblastogenesis conferred by Cdk5 depletion alone, suggesting that Cdk5 regulates osteoblast differentiation through MAPK pathway modulation. We conclude that Cdk5 is a potential therapeutic target to treat osteoporosis and improve fracture healing.

Effect of Zinc Galvanization on the Microstructure and Fracture Behavior of Low and Medium Carbon Structural Steels

引用

Engineering（科研） 2013年第8期5卷 656-666页

作者： ignatius C. Okafor Ronald J. O’Malley Kaushal R. Prayakarao Heshmat A. Aglan Mechanical Engineering Department Tuskegee University Tuskegee USA Nucor Steel Corporation Decatur USA Nucor Steel Corporation Marion USA

Microstructure and fracture behavior of ASTM 572 Grade 65 steels used for wind tower applications have been studied. Steels of two carbon level chemistries designed for this grade were used in the study. Fracture toughness of the steels was studied using 3-point bend test on samples coated with zinc and not coated with zinc. Lower carbon steel showed higher resistance to fracture than medium carbon steel after zinc galvanization. SEM study suggests that zinc and zinc bath additives that migrated to crack tips are responsible for the loss in ductility. The phenomenon of Liquid Metal Embrittlement (LME) is suggested to have taken place. Zinc bath additives traced at crack zones are suggested to have migrated at the zinc galvanizing temperatures.
