Self-management program for patients with chronic kidney disease (SMP-CKD) in Southern China: protocol for an ambispective cohort study.

Background: Chronic kidney disease (CKD) is a major global health problem. Short-term self-management has been considered to effect some renal and psychological endpoints. However, there are currently very few studies about self-management for CKD that a) have been scientifically designed by a theory-based framework and b) that evaluate the long-term effects and working mechanism.

Increasing CCL5/CCR5 on CD4+ T cells in peripheral blood of oral lichen planus.

Oral lichen planus (OLP) is a T cell-mediated autoimmune disease of oral mucosa, in which T helper 1 (Th1) cells are greatly involved. Chemokine CCL5 is required for T cells infiltration and activation. CCR5, one of its receptors, specifically expressed on Th1 cells among CD4(+) T cells, can be up-regulated by Th1 cytokines like interleukin2 (IL-2) and interferon-gamma (IFN-γ), and down-regulated by Th2 cytokines like IL-4.

Increased B7-H1 expression on peripheral blood T cells in oral lichen planus correlated with disease severity.

Background: Oral lichen planus (OLP) is a chronic and T cell-mediated autoimmune disease whose immunopathogenesis may involve antigen-presentation, T cells activation and migration as well as keratinocytes apoptosis. PD-1/B7-H1 pathway may have a unique function in regulating self-reactive T cells associated with inflammatory response and maintaining tolerance in peripheral tissues. In this study, we aimed to explore the contribution of PD-1/B7-H1 pathway to OLP.

Biologics, an alternative therapeutic approach for oral lichen planus.

Oral lichen planus (OLP) is generally accepted as a chronic and T-cell-mediated autoimmune disease, whose immunopathogenesis may involve antigen presentation, T-cell activation and migration as well as, possibly, tumor necrosis factor-alpha (TNF-α)-induced keratinocytes apoptosis. However, present treatment options for OLP are far from being satisfactory. Recent advances in understanding the pathogenesis of OLP, progress in biologics, and the success of biologic therapies in OLP indicate that biologic agents are facing expanding indications in OLP.

Activation of nuclear factor-kappa B correlates with tumor necrosis factor-alpha in oral lichen planus: a clinicopathologic study in atrophic-erosive and reticular form.

Background: Nuclear factor-kappa B (NF-kappaB) is believed to be involved in the pathogenesis of various inflammatory diseases, including oral lichen planus (OLP). The objective of the present study was to investigate the possible relationship between NF-kappaB activation and expression of tumor necrosis factor-alpha (TNF-alpha) in OLP and their expression pattern in relation to several clinical features.

Methods: Thirty OLP cases were divided into atrophic-erosive form (14 cases) and reticular form (16 cases) according to their clinical manifestations.
