Traditional Chinese Medicine Intervenes in Signaling Pathways Associated with CKD-MBD： A Review / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） has certain advantages in the treatment of chronic kidney disease-mineral and bone disorder （CKD-MBD）. In recent years， there have been many studies on the treatment of CKD-MBD by Chinese medicinal compounds and monomers. As revealed by literature retrieval， the research on the mechanism of Chinese medicine in intervening in signaling pathways related to CKD-MBD was mainly based on self-made Chinese medicinal compounds， and the action pathways involved fibroblast growth factor 23/Klotho （FGF23/Klotho） signaling pathway， Wnt/β-catenin signaling pathway， receptor activator of nuclear factor-κB/receptor activator of nuclear factor-κB ligand/osteoprotegerin （RANK/RANKL/OPG） system， and other signaling pathways. TCM can improve calcium and phosphorus metabolism and bone metabolism disorder， and regulate inflammatory reaction， oxidative stress， apoptosis， and autophagy by regulating this series of signaling pathways for the treatment of CKD-MBD. This paper introduced the research results of these signaling pathways and the mechanism of TCM in the treatment of CKD-MBD in order to provide ideas and references for the related research of Chinese medicine in the treatment of CKD-MBD.

Quality evaluation of clinical practice guidelines for obstetric venous thromboembolism based on AGREE Ⅱ / 中华妇产科杂志

Objective:To evaluate the quality of the current foreign clinical practice guidelines (CPG) on obstetric venous thromboembolism (VTE), providing reference for standardizing the prevention and treatment of domestic VTE clinical practice.Methods:The GPGs for the management of obstetric VTE published abroad from inception to July 2020 were electronically searched. Two researchers independently evaluated the quality of the included guidelines in accordance with the internationally recognized guideline evaluation tool, AGREE Ⅱ.Results:A total of 12 guidelines, 2 recommendations and 1 consensus for obstetric VTE were included, covering 3 continents and 9 countries, and the published time span was 2009-2020. The standardized scores of the six domain (scope & purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability and editorial independence) included in the guidelines were: 99.44%, 62.78%, 70.35%, 95.74%, 68.80% and 76.94% respectively, and the scores in each domain were ≥ 50.00%, indicating that the included CPGs were of good quality. Except for the domain scope & purpose, the ranges of the other five domains were ≥ 50.00%, suggesting that the quality of the CPGs differed significantly. Among the 15 included CPGs, 4 CPGs were level A (recommended), 11 CPGs were level B (recommended after being revised), and there was no CPG in level C (not recommended). The difference in the recommended content of obstetric VTE management mainly focused on the risk assessment, drug type, dosage and period.Conclusions:The overall quality of the CPGs for obstetric VTE management is high, while the quality of the CPGs varies greatly. In addition, there are differences in the recommended content of obstetric VTE management. More high-quality researches are required to provide evidence-based support for the improvement of the CPGs.
