Height at age 18 years is a strong predictor of attained education later in life: cohort study of over 950,000 Swedish men.
Adult body height has been related to socioeconomic position in cross-sectional studies. Intelligence， shared family factors， and non-familial circumstances may contribute to associations between height and attained education， but their relative importance has been difficult to resolve.A nation-wide record-linkage cohort study of over 950 000 Swedish men born 1950-75 followed with respect to attained education for up to 27 years after measurement of height at age 18 (baseline). The association between height and attained education in later life was investigated by logistic regression modelling with adjustment for age， geography， parental socioeconomic position， and cognitive ability. Shared family factors were accounted for in analyses of full-brother-pairs using conditional logistic regression.The odds ratio (OR) for attaining higher education 7-27 years after baseline was 1.10 [95% confidence interval (95% CI) 1.09-1.10] in fully adjusted models per 5 cm increase in height. Men taller than 194 cm were two to three times more likely to obtain a higher education as compared with men shorter than 165 cm. The association remained within brother-pairs， OR 1.08 (95% CI 1.07-1.10)， suggesting that non-familial factors contribute to the association between height and education attainment. A significant interaction (P < 0.0001) was found between year of birth， height， and attained education， showing slightly weaker associations among later birth cohorts.The strong positive association between height and educational achievement remaining after adjustment for year of birth， parental socioeconomic position， other shared family factors， and cognitive ability may reflect educational discrimination based on height although residual confounding cannot be ruled out.

摘 要： 目的探讨医院抗菌药物应用情况及用药合理性。方法随机抽取2009年5月份全部出院病历950份，进行回顾性调查。结果838例使用抗菌药物，抗菌药物使用率为88.2％；预防用药占71.6％，治疗用药占28.4％，内科系统72％为治疗用药，外科系统94％为预防用药；单一用药占56.2％，二联用药占38.9％，≥三联用药占4.9％；治疗用药送检率为69.7％，医院感染率为2.1％。结论抗菌药物管理是个系统工程，要加强抗菌药物知识更新培训和医务人员职业道德教育，以提高抗菌药物合理应用水平。
目的总结并分析近10年来第三 军医大学大坪医院收治的宫颈癌患者的临床特征。方法回顾性分析2004年1月-2013年12月第三军医大学大坪医院经病理证实的浸润性宫颈癌患者的临床 资料，并将患者按照不同年龄段分组，就其年龄构成、临床特征、病理类型、手术选择等进行分层研究。结果共纳入浸润性宫颈癌患者950例，平均年龄46.9 岁。不同年龄段的患者其临床特征、病理类型及手术方案的选择各有不同。从入院患者年龄构成来看，发病年龄呈逐年增长的趋势。结论不同年龄段宫颈癌患者发病 各有特征，应分年龄段制定防控措施。
Effect of a mutation at tyrosine 950 of the insulin-like growth factor I receptor on the growth and transformation of cells.
Recent evidence has shown that the -like growth factor I () receptor plays a major role in the establishment and maintenance of transformation. To identify domains in the that are necessary for transformation， the tyrosine at residue 950 of the cDNA was mutated to phenylalanine， and the plasmid expressing the mutant receptor was stably transfected into R- cells， which are embryo fibroblasts with a targeted disruption of the type 1 receptor for the -like growth factors. At variance with the wild-type receptor， the Y950 mutant receptor has lost its ability to transmit an -mediated mitogenic signal or to transform R- cells. These experiments show， for the first time， that tyrosine 950 of the is necessary for its mitogenic and transforming activities.
摘 要： 目的通过粤西某高校教职工颈椎体检结果进行分析，发现高校教职工颈椎突出问题，为教育工作者提高身体素质，促进工作质量提供客观的理论依据。方法针对粤西某高校全体教师职工950例进行常规颈椎体检，针对临床症状体征和颈椎X线片进行综合诊断，并对X线片进行分析，分为轻、中、重度，进行不同年龄组别，不同性别组别的对比分析。结果≤30岁组颈椎病发病率为15.15%;31-40岁组颈椎病发病率为51.09%;41-50岁组颈椎病发病率为67.98%;51-60岁组颈椎病发病率为78.79%;〉60岁组颈椎病发病率为75.97%;不同年龄组间颈椎病发病率差异有显著性，P〈0.05，发病率随年龄增加而增加;不同性别颈椎病发病率差异亦有显著性，P〈0.05，男性罹患颈椎病的概率大于女性。结论我校教职工颈椎病发病率较高，随年龄增加发病率不断增加，重度颈椎病患者也越多，男性颈椎病发病率明显高于女性，应当加强颈椎病的健康教育，通过改变生活习惯，增加运动等方式预防和改善颈椎病。
Objective To discuss the clinical features of the patients suffering from cervical cancer who visited Daping Hospital affiliated to Third Military Medical University in recent 10 years. Methods The clinical data of the patients who were pathologically diagnosed as invasive cervical cancer in Daping Hospital of TMMU from Jan. 2004 to Dec. 2013 were retrospectively analyzed. They were divided into different age groups and analyzed according to age， clinical features， pathological type， and surgical approach. Results Clinical data of 950 patients with invasive cervical cancer were reviewed in this study. The mean age of the patients was 46.9 years. The clinical features， pathological type， and surgical approaches were different in different age groups. Analysis of the age structure of the patients， the onset age of cervical cancer seemed to increase year by year. Conclusion The clinical features of cervical cancer are diversity in different age， and the strategy for controlling its development should be varied according to age.DOI： 10.11855/j.issn.0577-7402.2015.03.09
