3中国成人硒需要量研究显示文摘目的探讨使人体血浆硒蛋白P(SEPP1)达到饱和的硒摄入量,以评估硒需要量,为膳食硒参考摄入量DRIs的修订提供参考。方法对98名低硒健康受试者(体重平均58kg)进行为期40w的双盲补硒实验。随机分为七组,补硒(以硒蛋氨酸形式)剂量分别为0、21、35、55、79、102和125μg/d。定期检测血浆中谷胱甘肽过氧化物酶(GPX3)活性、SEPP1含量和硒含量等硒状态功能指标。选择剂量响应曲线的饱和平台起始点的相应摄入量作为该指标的需要量。结果在实验40w时,使血浆SEPP1含量达到饱和的硒摄入量为49μg/d;使血浆GPX3活性达到饱和的硒摄入量为35μg/d;血浆硒不能达到饱和平台,故不能用来作为评价硒需要量的指标。结论就当前人体实验而言,血浆SEPP1含量是反映硒营养状态和测定硒需要量的最佳指标。所以,满足SEPP1合成的硒摄入量49μg/d,经体重和个体变异等因素适当调节后,可作为人体硒需要量和修订膳食硒参考摄入量DRIs的参考。夏弈明 KE Hill 李平 徐家沅 周定友 RF Burk 2011营养学报2011,33,2:25

5Interleukin-1α, 6 regulate the secretion of vascular endothelial growth factor A, C in pancreatic cancer显示文摘Vascular endothelial growth factor (VEGF, namely VEGF-A) is an angiogenic polypeptide and VEGF-C is a lymphangiogenic polypeptide that has been implicated in cancer growth, invasion and metastasis. Several cytokines and growth factors play an important part in cancer progression. These cytokines and growth factors are the principal mediators of cancer cells-stromal cell interaction , which is critical for invasion of cancer cells to the surrounding tissues and metastatic dissemination to distant organs. In this study, we studied VEGF-A, C expression in cultured human pancreatic cancer cell lines and whether the presence of VEGF-A, C in the cell lines is regulated by cytokines interleukin-lct (EL-1α), and interleukin-6 (IL-6). METHODS: We used Northern blot and Western blot methods to analyze expression of the gene and protein of VEGF-A, C in all 6 tested cell lines (ASPC-1, CAPAN-1, MIA-PaCa-2, PANC-1, COLO-357 and T3M4) respectively. To analyze what is the regulator for this VEGF-A, C expression in pancreatic cancer,we used the reverse transcription -polymerase chain reaction (RT-PCR) method to analyze VEGF-A, C expression in cultured human pancreatic cancer cell lines (CAPAN-1 and COLO-357) under the stimulation with IL-1α (10μg/L) or IL-6 (100 μg/L). RESULTS:Northern blot analysis revealed the presence of the 4.1-kb VEGF-A mRNA transcript and 2.4-kb VEGF-C mRNA transcript in all 6 tested cell lines. Immunoblotting with highly specific anti-VEGF-A, anti-VEGF-C antibody revealed the presence of a molecular weight of 43-kDa VEGF-A protein and 55-kDa VEGF-C protein in all the cell lines. RT-PCR analysis revealed the levels of the VEGF-A and VEGF-C gene were 1-2 fold and a 1-fold increase in the COLO-357 cell line by stimulation with IL-la, however, no effect was found in the CAPAN-1 cell line. The levels of the VEGF-A and VEGF-C gene were 2-5 fold and a 1-fold increase in the CAPAN-1 cell line by stimulation with IL-6, but, no effect was found in the COLO-357 cell line. CONCLUSION:These findings suggested that the expression of VEGF-A, C and their regulation by IL-1α, IL-6 in pancreatic cancer contributes to the lymphatic and distant metastasis and the disease progression.Department of Hepatobiliary Surgery (Tang RF, Zhang FR, Peng L, Wang SX, Xiao Y and Zhang M) and Department of Dermatology (Wang SX), 4th Hospital, Hebei Medical University, Shijiazhuang 050011, China 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:6

7终末期肾病患者大血管和微血管内皮功能障碍与亚临床心功能不全的关系显示文摘终末期肾病(end-stagerenaldisease,ESRD)患者的心脏衰竭和心血管病死亡率较高,而我们对此缺乏深入透彻的了解,是否存在可变因素导致了这些高危患者发生心功能不全。为了评估血管内皮功能能否作为ESRD患者潜在的心功能不全的可变因素,研究人员应用横断面研究在一个控制良好的ESRD队列中,分析大血管和微血管功能障碍与左、右心功能不全的相关性。刘莉 叶鹏 Dubin RF Guajardo I Ayer A Mills C Donovan C Beussink L Scherzer R Ganz P Shah SJ 2016中华高血压杂志2016,24,9:5

18白质内的神经递质信号显示文摘脑白质是由许多有髓鞘的轴突组成,白质和灰质共同组成中枢神经系统,白质是中枢神经系统内信息快速传递的基础。有髓神经通路主要是由少突胶质细胞、星形胶质细胞及少量的小胶质细胞和少突胶质前体细胞构成。大部分白质内的神经递质信号主要存在于神经细胞胞体外,这提示这些神经递质除了具有完成神经元与神经元之间信息传递的功能外,还有其他生理功能。白质中的神经递质信号种类很多,已经证实的有谷氨酸能、嘌呤能(ATP和腺苷)、GABA能、甘氨酸能、肾上腺素能、胆碱能、多巴胺能、血清素能等信号递质,通过与各种离子型或代谢型受体结合发挥作用。轴突和胶质细胞都可以释放神经递质,也可以表达相应的受体。白质内神经递质信号的生理功能还需进一步研究,但研究已经证实谷氨酸和ATP介导的信号可激活胶质细胞上的钙离子通道,并调节轴突的传导功能。某项研究显示,在动作电位传播的过程中,轴突释放神经递质并与胶质细胞上的受体结合,通过少突胶质细胞来调节星形胶质细胞的稳态和髓鞘形成。星形胶质细胞也释放神经递质,与轴突上的受体相结合,增强动作电位的传播,维持信号电位沿长的轴突传播。白质内神经递质种类的多样性,提示它们有多种功能,对信号的传递有重要作用。白质内的神经递质信号现象很有可能也存在于大脑皮质和灰质,在这些部位的神经递质对于大脑的高级认知功能有更重要的作用。Butt AM Fern RF Matute C 唐颖馨 2014神经损伤与功能重建2014,9,6:2
