Netrin-1 (NT-1) is one of the axon-guiding molecules that are critical for neuronal development. Because of its structural homology to the endothelial mitogens, NT-1 may have similar effects on vascular network formation. NT-1 was shown to be able to stimulate the proliferation and migration of human cerebral endothelial cells in vitro and also promote focal neovascularization in adult brain in vivo. In the present study, we reported the delivery of NT-1 using an adeno-associated virus (AAV) vector (AAV-NT-1) into mouse brain followed by transient middle cerebral artery occlusion (tMCAO). We found that AAV vectors did not elicit a detectable inflammatory response, cell loss or neuronal damage after brain transduction. The level of NT-1 was increased in the AAV-NT-1-transduced tMCAO mice compared with the control mice. Furthermore, the neurobehavioral outcomes were significantly improved in AAV-NT-1-transduced mice compared with the control animals (P<0.05) 7 days after tMCAO. Our data suggests that NT-1 plays a neuronal function recovery role in ischemic brain and that NT-1 gene transfer might present a valuable approach to treat brain ischemic disorders.

众所周知,肠道菌群在调节宿主生理功能方面具有重要作用,如调节免疫和代谢平衡。近年来,越来越多证据表明肠道菌群能够通过肠-脑轴调节中枢神经系统功能,这为研究肠道和大脑间的相互作用关系开辟了一条新路径。本文首先介绍了肠道菌群与大脑相互作用的肠–脑轴分子机制,以及肠道菌群失调引发的神经系统功能紊乱;然后介绍了调节肠道菌群失衡是干预神经系统功能紊乱的潜在策略,如益生菌、益生元、合生元以及饮食等干预措施。目前关于肠道菌群–肠–脑轴方面的研究尚处在起步阶段,但继续深入阐明肠道菌群调节神经系统功能的分子机制不仅能揭示神经系统功能紊乱的新型病理机制,而且能够为神经系统功能紊乱提供潜在的诊断标志物和干预策略。

Splenic lymphoma with villous lymphocytes (SLVL) or splenic marginal zone lymphoma with circulating villous lymphocytes is rare, and prolymphocytic transformation of SLVL is rarer. At present, only one case of SLVL with t(8;14)(q24;q32) translocation has been reported. In this study, we report a case of B-lymphoproliferative disorder with villous lymphocytes harboring t(8;14)(q24;q32) chromosome translocation that we inclined to SLVL with a prolymphocytic transformation. A 73-year-old female showed marked hepatosplenomegaly and high lymphocytosis (lymphocytes>200×109/L). The abnormal lymphocytes had short coarse villi and round nuclei with prominent nucleoli. The immunophenotypes showed CD19+, CD20+, HLA-DR+, CD22+, CD5+, Kappa+, CD25dim, CD71dim, Lambda−, CD7−, CD10−, CD23−, CD34−, CD33−, CD13−, CD14−, CD117−, CD64−, CD103−, and CD11c−. The karyotype showed complex abnormality: 46XX,+3,−10, t(8;14)(q24;q32)[11]/46XX[9]. The cytoplasmic projection, immunological characteristics, and trisomy 3 chromosome abnormality supported the diagnosis of SLVL. However, the presence of prominent nucleoli and high lymphocytosis suggested prolymphocytic transformation, probably as a result of t(8,14) chromosome translocation. In this report, we described an unusual case of B-lymphoproliferative disorder with villous lymphocytes harboring t(8;14)(q24;q32) translocation, which could provide help in the diagnosis and differential diagnosis of B-lymphocytic proliferative diseases.

回顾分析50年来我国健康人群血脂水平的变化,结果显示血总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白胆固醇(LDL-C)随年龄而增高,50岁以前男女间无差别,50岁以后女性高于男性,城市居民高于农村居民;高密度脂蛋白胆固醇(HDL-C)随年龄的变化不明显,男性低于女性;血TC、TG和LDL-C随年代而增高,20世纪90年代末达最高峰,而HDL-C则下降;血TC高于正常者(>200~220 mg/dL)男性占17.8 %~54.9 %,女性占14.9 %~53.4 %,也随年代而增多;血脂水平的变化与饮食结构转变为低碳水化合物、高脂肪、高胆固醇有关。对策:恢复健康的饮食习惯,摄取平衡饮食;建立良好生活习惯,减少其他心血管病危险因素,特别建议进行体育锻炼;已有血脂异常,经饮食调节和体育锻炼3个月以上仍未见好转者,宜接受调脂药物治疗。

The purpose of this study is to characterize a meta-signature of differentially expressed mRNA in chronic kidney disease (CKD) to predict putative microRNA (miRNA) in CKD–mineral bone disorder (CKD–MBD) and confirm the changes in these genes and miRNA expression under uremic conditions by using a cell culture system. PubMed searches using MeSH terms and keywords related to CKD, uremia, and mRNA arrays were conducted. Through a computational analysis, a meta-signature that characterizes the significant intersection of differentially expressed mRNA and expected miRNAs associated with CKD–MBD was determined. Additionally, changes in gene and miRNA expressions under uremic conditions were confirmed with human Saos-2 osteoblast-like cells. A statistically significant mRNA meta-signature of upregulated and downregulated mRNA levels was identified. Furthermore, miRNA expression profiles were inferred, and computational analyses were performed with the imputed microRNA regulation based on weighted ranked expression and putative microRNA targets (IMRE) method to identify miRNAs associated with CKD occurrence. TLR4 and miR-146b levels were significantly associated with CKD–MBD. TLR4 levels were significantly downregulated, whereas pri-miR-146b and miR-146b were upregulated in the presence of uremic toxins in human Saos-2 osteoblast-like cells. Differentially expressed miRNAs associated with CKD-MBD were identified through a computational analysis, and changes in gene and miRNA expressions were confirmed with an in vitro cell culture system.

目的:了解正常排卵、小卵泡排卵以及未破裂卵泡黄素化患者的临床特征及观察后两者经阴道B超再次监排情况和促排卵治疗效果。方法:回顾性分析了正常排卵组(258例)、小卵泡排卵组(65例)及未破裂卵泡黄素化组(27例)患者年龄、排卵前卵泡大小和基础性激素水平差异,观察了后两组排卵障碍患者经阴道B超再次监排情况。并对两次监排结果一致的58例小卵泡排卵和25例未破裂卵泡黄素化患者进行克罗米芬促排卵治疗,分别观察了这两种排卵障碍患者的正常排卵率及临床妊娠率。结果:正常排卵组、小卵泡排卵组和未破裂卵泡黄素化组患者平均年龄、基础性激素水平均无显著性差异。三组间排卵前卵泡最大平均径线有显著性差异(F=117.9,P<0.01)。小卵泡排卵和未破裂卵泡黄素化的发生率分别为18.57 %和7.71 %。两者再次监排后,再发率分别为89.23 %和92.59 %。经克罗米芬促排卵联合黄体支持治疗后,小卵泡排卵组和未破裂卵泡黄素化组正常排卵率分别为70.69 %和80 %,临床妊娠率分别为29.31 %和48 %。结论:年龄、基础性激素水平不能预测是否正常排卵,经阴道B超监测是诊断小卵泡排卵以及未破裂卵泡黄素化的直观方法。不经过治疗两者再发率高,促排卵治疗联合黄体支持是治疗小卵泡排卵以及未破裂卵泡黄素化的有效方法。
