The TNF-α signaling pathway is a valuable target in the therapy of autoimmune diseases.TNF-α binds to two different receptors and exerts anti-inflammatory and anti-rheumatic effects.The drugs of anti-TNF-α are widely used in rheumatoid arthritis, such as infliximab, adalimumab etc.These TNF blockers have become invaluable tools to reduce damages induced by inflammation and allow recovery of the affected tissues.Unfortunately, this therapy has some drawbacks, such as increasing the risk of infection, malignancy and the incidence rate of new auto-immune diseases.Some of these effects are caused by the unwanted abrogation of beneficial TNF signaling.Therefore, elective antagonism of TNFR is an important approach to alleviate the side effects of TNF-α antibody.The medications specifically targeting the TNFR might have better applicability and safety.In this article, research progresses of TNF-α and its receptors in the therapy of rheumatoid arthritis were reviewed.

Research on the inflammatory bowel disease(IBD) is a hot topic in the field of digestive system disease.IBD mainly consists of ulcerative colitis(UC) and Crohn′s disease(CD).The pathogenesis of IBD has not been fully understood.So far, there is no specific medication for IBD.A number of novel medicines and preparations have emerged with the research progress on the pathogenesis of IBD.The research status on IBD drug therapy is briefly reviewed in this paper.

Aim To investigate the intraspecific variation of Carthamus tinctorius L. (safflower) and establish foundation for further breeding of safflower germplasm resource and screening the quality correlation genes. Methods Amplified fragment length polymorphism (AFLP) was carried out to analyze genetic variation of 28 safflower populations collected in China. Unweighed pair-group method of with arithmetical averages (UPGMA) cluster analysis was used to construct a dendrogram and to estimate the genetic distances among the populations. Results All populations could be uniquely distinguished using 12 selected primer combinations. Similarity coefficients ranged from 0. 48 to 0. 96 among the populations.Dendrogram revealed distinct segregation of all the cultivars into three main groups and one midst group.Conclusion Limited genetic diversity exists within the tested 28 collections at intra specific level and AFLP-based phylogeny was not absolutely consistent with that based on morphological characters may be due to the interaction effect between genotype and environment.
