目的了解医学生身体质量指数(BMI)状况,探讨BMI与身体素质间的关系。方法2021年11月份采取整群抽样方法随机抽取某医学院4316名本科生进行分析,参照《国家学生体质健康标准》对学生的身高、体重、肺活量、50米跑、800米/1000米、坐位体前屈、立定跳远、引体向上、仰卧起坐等身体素质指标进行测量。利用SAS 9.4软件进行独立样本t检验、χ^(2)检验、方差分析、Wilcoxon秩和检验统计分析,并采用Pearson和Spearman相关分析BMI与身体素质的关系。结果医学生BMI均值为(21.59±3.39)kg/m^(2),66.52%学生BMI值在正常范围之内,超重肥胖比例(18.58%)高于低体重比例(14.90%);不同性别医学生BMI状况分布差异有统计学意义(χ^(2)=247.22,P<0.05);不同年级间,男生与女生的BMI状况差异均有统计学意义(χ^(2)=72.05、204.82、P<0.05),男生超重肥胖检出率均高于女生(χ^(2)=71.16、162.10,P<0.05);男生BMI与速度跑和长跑呈正相关(r=0.265、0.296,P<0.05),与立定跳远、引体向上和肺活量体重指数呈负相关(r=-0.207、-0.442、-0.525,P<0.05),女生BMI与速度跑和长跑呈正相关(r=0.125、0.178,P<0.05),与立定跳远、仰卧起坐和肺活量体重指数呈负相关(r=-0.114、-0.052、-0.392,P<0.05);与坐位体前屈及PFI均不存在线性相关。男生与女生在身体素质、体质指数和肺活量体重指数上差异有统计学意义(P<0.01);在肺活量体重指数方面,男生低体重组优于正常体重组,正常体重组优于超重肥胖组(t=26.084、19.772、P<0.05),女生低体重组优于正常体重组,正常体重组优于超重肥胖组(t=9.024、9.804,P<0.05)。结论医学生超重肥胖发生率较高,超重肥胖影响医学生的体质健康。

随着全球化进程的不断推进,国内进出口贸易规模逐年扩大,食品安全问题也日益受到关注。进出口罚没食品主要是指在进出口环节被海关等执法部门查获的违法食品,这些罚没食品通常会涉及质量、标签以及假冒伪劣等问题,一旦这些产品流入或者流出,则会对消费者的饮食安全造成严重影响。而在我国法律法规的规定下,执法部门有权利罚没这些问题食品,并具备销毁罚没食品的权利。为此,本文将对进出口罚没食品类型展开分析,并论述进出口罚没食品的销毁技术,以期不断提升我国食品安全管理水平。

There is an ongoing professional tension in the LIS community about the structural relationship between LIS education and professional practice in terms of the best way in fostering and strengthening the education program for librarianship. This is increasingly becoming an urgent issue due to the pressing demands of a rapidly changing information environment. The divergent viewpoints and approaches of these two professional bodies toward one of the most important issues of their common interest are further aggravated by each of their own entrenched professional provincialism as well as by their isolated professional undertakings. These factors are inevitably threatening the vitality and thriving of both bodies. In an attempt to ease this developing trend of professional tension from evolving further into a mutually self-destructive situation, it is suggested in this paper that librarians and library educators should join hands together and transcend their own provincial interest by solving this thorny issue of this professional tension which has multi-dimensional adverse impacts on both professional enterprises. The collaboration of these two parties can serve as a catalyst to bring the two professional groups together more closely and in an organic way to reconstruct a sound LIS educational program with an integral component of professional practicum such as the case of National Science Library, the Chinese Academy of Sciences(CAS). The author believes that the integration of LIS education with professional practicum being offered at National Science Library of CAS(NSL) may shed light onto a new vista of hope for those who are so dedicated themselves to the changes of the LIS education.

目的:总结黄河三角洲地区小肠溃疡患者的病因构成、内镜表现及临床特点,为临床诊治提供依据。方法:回顾性分析2020年5月1日—2023年3月1日于滨州医学院附属医院经小肠镜或胶囊内镜首次诊断为小肠溃疡的135例患者的临床资料。结果:黄河三角洲地区小肠溃疡多发于40~59岁,男女比例为1.55︰1。小肠溃疡的病因主要以克罗恩病最多见,临床表现多为腹痛、腹泻、便血和黑便,影像学检查特点为小肠管壁增厚、肠系膜淋巴结肿大及小肠管腔狭窄。小肠镜及胶囊内镜检出率分别为26.83%及8.67%,常见溃疡部位为回肠、回盲部和空肠,内镜下溃疡特点以不规则样、纵行、环形、节段性为主,病理改变主要是黏膜慢性炎和伴炎细胞浸润。结论:小肠溃疡的病因复杂,临床特点缺乏特异性,小肠镜及胶囊内镜有助于小肠溃疡的诊断,但内镜下的表现常有重叠,病理活检在疾病的诊断中仍具有一定的局限性,应进一步探究CT等辅助检查在小肠溃疡诊断及鉴别诊断中的作用。
