甲减患者总同型半胱氨酸水平及其相关因素分析

目的：探讨甲减患血浆总同型半胱氨酸（tHcy)的变化及其与叶酸,维生素B12,血清胆固醇的相关关系,方法：应用荧光偏振免疫发光技术测定45例甲减患及48例正常对照tHcy,叶酸,维生素B12水平,应用生化技术测定血清总胆固醇;同一参数在甲减组与对照组间进行t 检验,tHcy 与各参数间的关系采用Spearman等级相关,结果：甲减组tHcy及血清胆固醇显高于对照组;甲减组叶酸及维生素B12显代于对照组,甲减患tHcy与叶酸,维生素B12分别呈显负相关,与胆固醇呈正相关,但无统计学意义。结论：甲减患tHcy和胆固醇升高可加速其动脉硬化的发生及发展,加速冠心病的进程,补充叶酸及维生素B12治疗有望在一定程度上降低tHcy的水平,从而降低甲减患冠心病的发生率。     

Comments on the Serial Homology and Homologues of Vertebral Lateral Projections in Crocodylia (Eusuchia)

The literature on crocodylian anatomy presents the transverse process in an ambiguous meaning, which could represent all lateral expansions derived from the neural arch, including vertebrae from cervical to caudal series, or in a more restrictive meaning, being applied only to lumbar vertebrae. The lateral expansion of sacral and caudal vertebrae usually referred to as the transverse process has been discovered to be fused ribs, bringing more ambiguity to this term. Therefore, with the lack of a definition for transverse process and other associated terms, the present work aims to propose a nomenclatural standardization, as well as definitions and biological meaning, for vertebral rib related structures. Vertebra obtained from museum collections from a total of 87 specimens of 22 species of all extant Crocodylia genera were studied. All vertebrae, except cervical and first three dorsal, exhibit transverse processes. The transverse process is more developed in dorsal and lumbar vertebrae than in sacral and caudal vertebrae in which it is suppressed by the fused ribs. The serial homology hypotheses here proposed can also be aplied to other Crurotarsi and saurischian dinosaurs specimens. This standardization clarifies the understand of the serial homology among those homotypes, and reduces the ambiguity and misleadings in future work comparisons.

血清HCY和NLR在2型糖尿病肾病中的诊断价值研究

目的利用受试者工作特征曲线(ROC曲线)评价血清同型半胱氨酸(HCY)、中性粒细胞/淋巴细胞比值(NLR)及其联合诊断在2型糖尿病肾病中的诊断价值。方法随机选取2016年6月—2018年6月本院收治的2型糖尿病患者100例,根据临床诊断分为糖尿病肾病组43例和糖尿病组57例,记录2组患者性别、年龄等基线资料以及血清HCY、NLR检测结果。结果糖尿病肾病组血清HCY、NLR水平均明显高于糖尿病组,差异有统计学意义(P<0.05)。其中,血清HCY、NLR以及联合试验诊断糖尿病肾病ROC曲线下面积分别为0.782、0.635、0.793,灵敏度分别为79.07%、51.16%、67.44%,特异度分别为68.42%、64.91%、89.47%。Z检验结果显示,血清HCY诊断糖尿病肾病ROC曲线下面积大于NLR(P<0.05),联合试验诊断糖尿病肾病ROC曲线下面积大于NLR(P<0.05),HCY诊断糖尿病肾病ROC曲线下面积与联合试验差异无统计学意义(P>0.05)。结论血清HCY在2型糖尿病肾病中的诊断价值高于NLR,尚未发现二者联合试验能够提高其诊断价值。
