Methods: Fifty-five cases of IUGR were divided into two groups, 30 cases in the CHM group treated with CHM and the 25 in the control group treated with amino acids. The effect of CHM treatment was observed and compared with that of the control group, normal pregnancy group and non-treated IUGR group. Results: Body weight of the newborns in the CHM was markedly higher than that in the control group. Not only the maternal fundal height (FH) and the abdominal circumference (AC), but also the fetal growth parameters, including biparietal diameter, head circumference (HC), and femur length (FL) in the CHM group increased much faster than those in the control group. After CHM treatment, the maternal serum levels of estriol (E3) and human placental lactogen (hPL) approached to those in the normal pregnancy group, but the control group,in comparison with the normal pregnancy group, was significantly different. The umbilical venous plasma concentration of essential amino acids in both treated groups improved, but the improvement in the CHM group was more significant than that in the control group. No apparent adverse effect of CHM was observed in either mother or fetus.Conclusion: CHM for supplementing Kidney and Qi and activating blood circulation was more effective in improving placental function and enhancing amino acid transportation than amino acid展开更多

Oligodendrocyte precursor cells are neural stem cells that are important for myelin repair and regeneration. In the present study, Erhuang capsule effectively improved clinical symptoms and neurological function scores, reduced mortality and promoted recovery of neurological functions of mice with experimental autoimmune encephalomyelitis. The mechanism of action involved significant increases in oligodendrocyte precursor cell proliferation in specific regions of the brain and spinal cord, increased oligodendrocyte lineage gene 2 expression and enhanced oligodendrocyte precursor cell differentiation.展开更多

Methods： CIA rats were generated by subcutaneous injection of bovine collagen type-Ⅱ at the tail base. Sixty CIA rats were randomly assigned（10 animals/group） to： model, methotrexate（MTX）-treated（0.78 mg/kg body weight）, and WJR-treated（22.9 g/kg） groups. Healthy normal rats（n=10） were used as the normal control. Treatments or saline were administered once daily by oral gavage. Rats were sacrificed at day 28 post-treatment and knee synovium and peripheral blood serum were collected. Toe swelling degree and expression of RANKL, OPG, and LIGHT were determined by Western blot and immunohistochemistry. Results： Compared with the normal group, toe swelling degree was significantly increased in the model group（P〈0.01）. After treatment, toe swelling degree decreased significantly in the WJR and MTX groups compared with the model group（P〈0.01）. Compared with the normal group, expression of RANKL and LIGHT were significantly increased and OPG significantly decreased in peripheral blood and synovium of the model group（P〈0.01）. Conversely, RANKL and LIGHT expression were significantly reduced and OPG increased in the WJR and MTX groups compared with the model group（P〈0.01）. No statistically significant difference existed between WJR and MTX groups. Conclusion： WJR likely acts by reducing RANKL expression and increasing OPG expression, thus inhibiting RANKL/RANK interaction and reducing LIGHT expression, thereby inhibiting osteoclast formation/activation to block bone erosion.展开更多
