RESUMEN
Diffuse large B-cell lymphoma (DLBCL) is the most common malignant lymphoma in China,which mostly starting from the lymph nodes.The studies find that the expression of NLRC5,member of nucleotide-binding oligomerization domain-like receptor (NLR) family,is evident in the lymphoid cells,which is likely to be an important basis for lymphocyte tumorigenesis.NLRC5 can block the nuclear factor-κB (NF-κB),a core component of signal transduction pathway,and affect the development of tumor.While continuing activation of NF-κB is a necessary condition for DLBCL cell survival.Therefore,NLRC5 is likely to inhibit excessive inflammation,thereby inhibiting the function of DLBCL,which promises to be a new target for immunotherapy treatment of DLBCL.
RESUMEN
Objective To investigate the changes of uveoscleral pathway by an I1 receptor agonist,moxonidine,and with pretreatment of antagonists topical administration,and to study the mechanism that moxonidine improves uveoscleral outflow.Methods Moxonidine was administered unilaterally and topically to rabbits and with pretreatment of the antagonists,namely,prazosin,yohimbine and efaroxan.FITC-BSA,a tracer agent,was injected into the anterior chamber after moxonidine treatment or with pretreatment of the antagonists.Frozen sections were undertaken at different time points between 2 to 10 h.Fluorescence intensity was observed in the sites of uveoscleral pathway in the sections by fluorescence microscopy.Results Bilateral fluorescence intensity treated with moxonidine was more intense than that with placebo,and the most intense regions of fluorescence were ciliary body and superchoroidal space.Fluorescence intensity by prazosin pretreatment was not significantly different compared to that by moxonidine,while yohimbine and efaroxan pretreatment decreased the intensity compared with moxonidine(P
RESUMEN
Objective To appraise therapeutic effects of tubeimoside on herpes simplex keratitis of rabbits. Methods HSV-1 (SM_(44) strain) is recovered on monolayers of BHK-21 cell cultures, then rabbit model of HSK was established after inoculation. After 0.2g/L Tu topically given, all eyes are examined by using slit-lamp-microscopy, and corneal samples were observed for ocular changes under transmission and scanning electromicroscope. (Results )Differences were significant in the three groups of corneal involvement scores. 0.2g/L Tu can obviously reduce corneal involvement area, and can also help to rehabilitate affected corneal epithelial cells. Conclusion Tu agent is able to cure experimental HSK to a certain degree, however, is less effective on HSK than acyclovir.
