1.Updates on the relationship between vitamin D and epilepsy
International Journal of Pediatrics 2016;43(12):948-952
Vitamin D adjusts the body′s absorption and utilization of calciumand phosphorus. Vitamin D deficiency is closely related to incidence of many disease. Several disorders,both systemic and those of the nerv-ous system,have been linked with vitamin D deficiency. Neurological disorders with a vitamin D link include but are not limited to multiple sclerosis,Alzheimer and Parkinson disease,as well as cerebrovascular disorders. In re-cent years,studies have found that the vitamin D may play a critical role in the pathogenesis of epilepsy and pos-sess certain anticonvulsant effects. This article summarized the role of vitamin D in the nervous system and epi-lepsy,the level of serum vitamin D and the correlation of the polymorphism of its receptor genes with epilepsy. The review also summarizes the interaction between antiepileptic drugs and vitamin D.

Acta Anatomica Sinica 1955;0(03):-
Objective To investigate the responses of astrocytes and neurons in rat lumbosacral spinal cord and medulla oblongata induced by chronic colonic inflammation,and the relationship between activated astrocytes and neurons.Methods Thirty-three male Sprague-Dawley rats were randomly divided into two groups.In treated group(n=17),colonic inflammation was induced by intraluminal administration of trinitrobenzenesulfonic acid(TNBS) in rats;In non-treated group(n=16),saline was intraluminally administered.The lumbosacral spinal cord and medulla oblongata were removed 3,7,14 and 28 days after intraluminal administration and processed for anti-GFAP,Fos and GFAP/Fos immunohistochemistry. Results Most activated GFAP positive astrocytes were distributed in the superficial laminae(Ⅰ-Ⅱ),intermediolateral nucleus(lamina Ⅴ),posterior commissural nucleus(laminae Ⅹ) and anterolateral nucleus(laminae Ⅸ) in lumbosacral spinal cord.Fos positive neurons were mainly expressed in the deeper laminae of the spinal cord(Ⅲ-Ⅳ,Ⅴ-Ⅵ).In the medulla oblongata,both GFAP-IR astrocytes and Fos-IR neurons were mainly distributed in medullary visceral zone(MVZ),which is composed of the nucleus of solitary tract(NTS),ventrolateral medulla(VLM) and intermediat reticular(IRt).The density of GFAP positive astrocytes in the spinal cord in treated rats 3,7 and 14 days after TNBS administration was significantly higher than that in non-treated rats(P0.05).Conclusions The astrocytes in lumbosacral spinal cord and medulla oblongata can be activated by colonic inflammation.The response of astrocytes decreased with the recovery of the colonic inflammation.Activated astrocytes are closely related to activated neurons in MVZ.

Objective The aim of this study was to investigate Fos expression in rat lumbarsacral spinal cord and medulla oblongata induced by chronic colonic inflammation. Methods Twenty six male Sprague Dawley rats were divided into three groups: group 1, colonic inflammation was induced in sixteen rats by intraluminal instillation of trinitrobenzenesulfonic acid (TNBS); group 2, saline was instilled intraluminally in eight rats; group 3, no stimulation was given in 2 rats. After 3, 7, 14 and 28 days of instillation, lumbarsacral spinal cord and medulla oblongata were removed and processed for Fos immunohistochemical staining. Results Fos neurons induced by TNBS instillation were mainly distributed in deep laminae (laminae Ⅲ Ⅳ,Ⅴ Ⅵ) in spinal dorsal horn and in medullary visceral zone in medulla oblongata. The number of Fos cells in the spinal cord and medullary visceral zone was significantly higher in rats after 7 and 14 day of TNBS instillation compared with that of controls. After 28 days of TNBS instillation, the number of Fos neurons in the medullary visceral zone decreased and became comparable to that of control group. However, the number of Fos cells (54.1?16.3) in the spinal cord in some rats was still significantly higher than that of controls (12.2 ?2.6, P
