ABSTRACT

Diabetic kidney disease (DKD) is the primary cause of mortality among diabetic patients. With the increasing prevalence of diabetes, it has become a major concern around the world. The therapeutic effect of clinical use of drugs is far from expected, and therapy choices to slow the progression of DKD remain restricted. Therefore, research on new drugs and treatments for DKD has been a hot topic in the medical field. It has been found that rhein has the potential to target the pathogenesis of DKD and has a wide range of pharmacological effects on DKD, such as anti-nephritis, decreasing blood glucose, controlling blood lipids and renal protection. In recent years, the medical value of rhein in the treatment of diabetes, DKD and renal disease has gradually attracted worldwide attention, especially its potential in the treatment of DKD. Currently, DKD can only be treated with medications from a single symptom and are accompanied by adverse effects, while rhein improves DKD with a multi-pathway and multi-target approach. Therefore, this paper reviews the therapeutic effects of rhein on DKD, and proposes solutions to the limitations of rhein itself, in order to provide valuable references for the clinical application of rhein in DKD and the development of new drugs.

ABSTRACT

Objective:To investigate the feasibility of using marrow stromal cells (MSC) as seed cells and three-dimensional porous nano-hydroxylapatite as scaffolds for constructing tissue-engineered bone.Methods:MSC from rat were cultured and induced to differentiate into osteoblasts in vitro. And then these induced cells were identified and seeded onto three-dimensional porous nano-hydroxylapatite scaffolds, cultured for 15 days in vitro. Scanning electron microscopy was used to evaluate the growth of these induced cells on three-dimensional porous nano-hydroxylapatite scaffolds. Results: The activity of alkaline phosphatase (ALP) and the secretion of osteocalcin of MSC from rat appeared and were increased gradually along the culture. The cells seeded on three-dimensional porous nano-hydroxylapatite scaffolds could adhere and proliferate well, and come into being many tiny calcium nodules and collagenous fibers. Conclusion:The data demonstrated that the new developed culture method is conducive to MSC’s differentiating and proliferating into osteoblasts that have a fine activity and the three-dimensional porous nano-hydroxylapatite may be considered as a suitable scaffold for the seeded cells. Using marrow stromal cells as seed cells and three-dimensional porous nano-hydroxylapatite as scaffolds is advantageous for constructing tissue-engineered bone.
