Relevant policies research on traditional Chinese medicine equipment / 数字中医药（英文）

@#Traditional Chinese medicine (TCM) equipment is the industry representative possessing independent intellectual property rights and unique Chinese characteristics. By integrating TCM and information technology, TCM equipment is experiencing an unprecedented period of opportunity. Here, based on the practical significance, we reviewed the recent series of policies to promote the TCM equipment development. In accordance, we analyzed the current main problems and causes, and finally put forward some policy demand and suggestions to boost TCM equipment industry.

Co-culture of Mesenchymal Stem Cells with Umbilical Vein Endothelial Cells under Hypoxic Condition / 华中科技大学学报（医学）（英德文版）

By co-culturing humm mesenchymal stem cells (hMSCs) and human umbilical rein endothelial cells (HUVECs) under hypoxia and creating a microenvironment similar to that of transplanted hMSCs for the treatment of avascular ni ANFH,the effect of hMSCs on survival,apoptosis,migration and angiogenesis of human umbilical vein endothelial cells (HUVECs) under the hypoxic condition were investigated in vitro.hMSCs and HUVECs were cultured and identified in vitro.Three kinds of conditioned media,CdM-CdMNOR,CdM-CdMHYP and HUVEC-CdMHYP were prepared.HUVECs were cultured with these conditioned media under hypoxia.The survival rate,apoptosis rate,migration and angiogenesis of HUVECs were respectively detected by CCK-8,flow cytometry,Transwell and tube formation assay.The content of SDF-1α,VEGF and IL-6 in CdM was determined by ELISA.Our results showed that hMSCs and HUVECs were cultured and identified successfully.Compared with MSC-CdMNOR and HUVEC-CdMHYP groups,the survival rate,migration and angiogenesis of HUVECs in MSC-CdMHYP group were significantly increased while the apoptosis rate was declined (P＜0.05).Moreover,the expression of SDF-1a VEGF and IL-6 in MSC-CdMHYP group was up-regulated.Under hypoxia,the apoptosis of HUVECs was inhibited while survival,migration and angiogenesis were improved by co-culture of hMSCs and HUVECs.The underlying mechanism may be that hMSCs could secrete a number of cytokines and improve niche,which might be helpful in the treatment of femoral head necrosis.
