Sex-biased autophagy as a potential mechanism mediating sex differences in ischemic stroke outcome

Stroke is the second leading cause of death and a major cause of disability worldwide, and biological sex is an important determining factor in stroke incidence and pathology. From childhood through adulthood, men have a higher incidence of stroke compared with women. Abundant research has confirmed the beneficial effects of estrogen in experimental ischemic stroke but genetic factors such as the X-chromosome complement can also play an important role in determining sex differences in stroke.

Glial regenerative response in the imaginal discs of Drosophila melanogaster

<正>Glial cells play a key role during nervous system development and actively participate in all the cellular processes involved in maintaining its structural robustness and functional plasticity.In response to neuronal damage,glial cells proliferate,migrate to the injured region and change their morphology,function,and behavior     

Gangliosides in nervous system development,regeneration, and pathologies

Gangliosides, sialic acid-containing sphingolipids, are major constituents of neuronal membranes. According to the number of sialic acids and the structure of the oligosaccharide chain, gangliosides can be classified as simple or complex and grouped in different ganglio-series. Hundreds of gangliosides have been identified in vertebrate cells, with different expression patterns during development and related to several physiological processes, especially in the nervous system. While GD3 and its ...     

新疆15～44岁HIV/AIDS青年患者中医症状及证候调查研究

目的:调查新疆地区15~44岁青年艾滋病患者常见中医症状和证候。方法:通过收集886例新疆青年HIV/AIDS患者病历,建立病历基本信息提取表,内容包括人口学信息、诊断、症状、中医证候等信息。结果:新疆地区青年最常出现的症状以乏力(52.7%)、腰膝酸痛(50.8%)、健忘(44.8%)、口干(43.6%)、烦躁(41.4%)、头痛(40.0%)、肢体麻木(34.6%)、心悸(34.2%);证候分布以虚证454例次占51.3%为多,其次为虚实夹杂证288例次占32.5%,气阴两虚(25.1%)、气虚湿阻(23.1%)、肝郁气滞(12.1%)、肝肾阴虚(12.1%)、气郁痰凝(6.7%)、肺卫不固(6.3%)为多。结论:新疆青年HIV/AIDS患者中医症状以乏力、腰膝酸痛、健忘为多,从证候分布上以虚证、虚实夹杂证为多,气阴两虚、气虚湿阻、肝郁气滞多见。     

维吾尔医“库西提”法炮制技术规范化研究及巴豆脂肪油含量测定

目的:评价维吾尔医“各立衣克买提”泥法炮制技术和在这种炮制方法前提下改进的新“库西提”法炮制技术对巴豆中脂肪油的含量测定的影响。方法:利用两种炮制方法炮制生巴豆,按《中国药典》2015年版一部巴豆项下的脂肪油含量测定方法进行测定。结果:采用这两种方法炮制的巴豆根据炮制时间不同脂肪油含量依次递减。结论:采用新“库西提”法炮制技术炮制的巴豆的脂肪油含量明显降低。     

miR-29a靶向调控CLDN1抑制肝癌细胞增殖的实验研究

目的:探讨miR-29a在肝癌组织中的表达水平，及其对人肝癌细胞增殖能力的影响。方法:通过RT-PCR测定肝癌组织及非肝癌组织中miR-29a的表达水平；将携带miR-29a的脂质体miR-29a mimic、空载体miR-NC以及miR-29a抑制剂anti-miR-29a转染入肝癌细胞系HepG2和HLE，通过RT-PCR方法检测miR-29a对肝癌细胞系HepG2、HLE增殖能力影响；通过Targetscan软件预测miR-29a靶基因，采用Western blot及荧光素酶实验验证。结果:与非肝癌组织比较，miR-29a在肝癌组织中表达下调，MTT实验提示:miR-29a高表达组肝癌细胞增殖能力较弱，miR-29a低表达组肝癌细胞增殖能力提高。Targetscan软件提示:CLDN1可能为miR-29a靶基因，Western blot及荧光素酶实验提示:与阴性对照组相比，miR-29a高表达组内CLDN1表达下降，相反miR-29a低表达组内CLDN1表达增加。结论:miR-29a在肝癌细胞及组织中表达下调，并且可能通过调控CLDN1影响肝癌细胞增殖能力。
