ABSTRACT

Objective To understand the incidence of hemolytic disease in newborn (HDN)among the newborns with jaundice and the coincidence degree of the blood group serological results and the clinical diagnosis in HDN.Methods The microcolumn gel method was adopted to detect the 3 serological indexes in 276 jaundice newborns of maternal fetal blood group incompatibility,in-cluding the direct antiglobulin test,free antibody test and antibody release test.Results 108 cases of HDN were clinically diagnosed with the positive rate of 39.13%.The positive detection rate in newborns with 0-2 d old was highest(50.00%).Conclusion The serological test can provide the basis for the early diagnosis and treatment of HDN.Collecting the specimen as early as possible can improve the positive diagnosis rate of HDN.

ABSTRACT

Osteoclasts, derived from multipotent myeloid progenitor cells, play homeostatic roles in skeletal modeling and remodeling, but may also destroy bone in pathological conditions such as osteoporosis and rheumatoid arthritis. Osteoclast development depends critically on a differentiation factor, the receptor activator of NF-kappaB ligand (RANKL). In this study, we found that the hexane soluble fraction of the common fig Ficus carica (HF6-FC) is a potent inhibitor of osteoclastogenesis in RANKL-stimulated RAW264.7 cells and in bone marrow-derived macrophages (BMMs). HF6-FC exerts its inhibitory effects by suppression of p38 and NF-kappaB but activation of ERK. In addition, HF6-FC significantly decreased the expression of NFATc1 and c-Fos, the master regulator of osteoclast differentiation. The data indicate that components of HF6-FC may have therapeutic effects on bone-destructive processes such as osteoporosis, rheumatoid arthritis, and periodontal bone resorption.
