Objective To explore the effects of parthenolide (PTL) on high glucose-stimulated cell proliferation, NF-κB activation and monocyte chemoattractant protein-1 (MCP-1) expression in rat mesangial cells (MCs). Methods MCs were cultured in normal glucose (5.6 mmol/L), high glucose (30 mmol/L), or high glucose with PTL. MTT assay was used to detect the cell proliferation. MCP-1 content in the supernatant was measured by ELISA, and the level of IκBα was detected by Western blotting to reflect NF-κB activity. EMSA method was used to measure the activation of NF-κB. Results MC proliferation, MCP-1 expression and NF-κB activation were significantly enhanced and the expression of NF-κB-binding protein IκBα was obviously reduced in cells cultured in high glucose. Application of PTL obviously abolished the effects of high glucose. Conclusion PTL can suppress high glucose-stimulated NF-κB activation and MCP-1 expression in rat MC. These data provide a theoretical basis for the clinical application of PTL in prevention and control of diabetic nephropathy.

OBJECTIVETo investigate the effect of the serum of rats fed with Shenkang pill in regulating monocyte chemoattractant protein 1 (MCP-1) expression induced by advanced oxidation protein products (AOPP) in mouse podocyte clone 5 (MPC5) and explore the underlying mechanism.

METHODSMPC5 cultured in vitro were incubated for different time lengths in the presence of different concentrations of serum of rats medicated with Shenkang pill, and the cell proliferation was assessed using MTT assay. In MPC5 treated with AOPP prior to exposure to the rat serum, the changes in the protein expressions of p38MAPK and IκBα were examined with Western blotting, NF-κB p65 nuclear translocation was analyzed with immunofluorescence assay, and MCP-1 expression in the supernatant was determined using ELISA kits.

RESULTSThe medicated rat serum time- and concentration-dependently promoted the proliferation of MPC5, with the optimal serum concentration of 5% and incubation time of 24 h. AOPP significantly increased MCP-1 expression in the cell supernatant in a time-and concentration-dependent manner; pretreatment with SB203580 (a p38 inhibitor) or parthenolide (a NF-κB inhibitor) significantly decreased MCP-1 expression, and treatment with the medicated serum significantly decreased AOPP-induced MCP-1 expression. AOPP concentration-dependently increased the protein expression of P-p38 but decreased that of IκBα. Both the medicated serum and SB203580 increased IκBα protein in AOPP-induced cells, but the effect was more obvious with the medicated serum. The medicated serum also decreased NF-κB p65 nuclear translocation in AOPP-induced MPC5.

CONCLUSIONShenkang pill-medicated serum can decrease AOPP-induced expression of MPC-1 in MPC5 by regulating p38MAPK/NF-κB to mediate its anti-inflammatory effect. This finding provides a new theoretical basis for the application of Shenkang pill to treat diabetic nephropathy.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.
