Zhongshan Daxue xuebao. Yixue kexue ban, 1988 本文用扫描电镜观察了经伊文思兰染的五周龄、五月龄和一年龄三个不同年龄组莱亨鸡受高脂血症分别影响4周和8周后主动脉内皮发生的形态变化。实验显示各年龄正常血脂组伊文思兰染区已出现内皮浅表性损伤。高血脂组兰染区内皮出现多发性“园球状隆起”性病灶,其实质是内皮细胞高度肿胀与泡沫样变性。一年龄组内皮泡沫样变性发生时间慢于另两个年龄组,提示幼年动物内皮比成年动物更易受高脂血症的作用而迅速发生泡沫样变性。内皮表面在正常血脂与高脂血症时,都有单核细胞粘附,但在高脂血症时单核细胞较活跃并可见插于内皮细胞间 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2009 【目的】 了解高龄妇女体外授精-胚胎移植(IVF-ET)的年龄界限值和影响高龄妇女IVF-ET妊娠成功率的因素。【方法】 选择三级甲等医院生殖医学中心1999年11月至2006年6月进行IVF-ET的年龄大于或等于35岁的高龄妇女共2 144周期;同期进行IVF-ET的年龄小于35岁的妇女周期数为5 559。分别比较≥35岁和 < 35岁组以及35 ~ 36,37 ~ 38,39 ~ 40及≥41岁组的妊娠率。该研究剔除了生育情况随访资料欠完全的患者,他们均为妊娠试验阳性和部分临床妊娠患者。【结果 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2013 【目的】 探讨高龄早期复发性流产患者的流产原因。【方法】 回顾性分析２００８年１月至２０１２年１０月，在我院诊治的高龄早期复发性流产患者的病历资料，对已行系统病因学检查，并且流产后成功行绒毛染色体分析的８２例患者的病因分布进行分析。并比较了高龄早期复发性流产与高龄偶发性早期流产的绒毛染色体异常发生率，原发性流产与继发性流产的病因分布，不同流产次数的复发性流产患者的病因分布。【结果】 高龄偶发性流产的绒毛染色体异常发生率（８５．１％）高于复发性流产的染色体异常发生率（６７．１％），（Ｐ ＜ ０．０５ ...

, 2008 目的研究1998～2005年中国高龄老人的生活质量和生活满意度。方法依据1998～2005年《中国老年人健康长寿调查数据库》四次调查数据,分析高龄老人的生活质量和生活满意度。结果大多数高龄老人健康自评中上、经济来源靠家人、能及时治病、与家人同住、室内活动无需帮助,生活满意度评分居中上水平; 但2002年健康自评较差、享有养老金比例较低、与家人同住比例较低和独居比例较高,生活满意度评分较低。与1998年被试跟踪调查结果类似。结论1998～2005年中国大多数高龄老人的生活质量和生活满意度居中上水平 ...

Equine Veterinary Journal, EarlyView.Abstract Background The middle conchal sinus (MCS) (ethmoidal sinus) remains one of the least understood equine paranasal compartments. Despite recognition of its involvement in sinonasal disease, disorders of the MCS often remain underdiagnosed in the absence of computed tomographic (CT) imaging due to limited anatomical understanding and challenges ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

How identity bias affects perceptions of conservation messages on social media
Conservation Biology, EarlyView.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.
