BACKGROUND: Studies have shown that there is a certain correlation between programmed osteocyte death and steroid-induced avascular necrosis of the femoral head, and there is an interaction between autophagy and apoptosis. Endoplasmic reticulum stress pathway is involved in the regulation of osteocyte autophagy and apoptosis. OBJECTIVE: To review the related pathways of autophagy and apoptosis regulated by endoplasmic reticulum stress, and summarize the research progress of autophagy and apoptosis pathways in the pathogenesis of steroid-induced avascular necrosis of the femoral head. METHODS: A computer-based online retrieval of PubMed, Web of Science, CNKI and WanFang databases was performed for relevant literatures published from database inception to May 2020 with the keywords of “steroid; necrosis of the femoral head; cell autophagy; ER stress; unfolded protein response” in Chinese and English, respectively. The articles concerning autophagy and apoptosis regulating steroid-induced avascular necrosis of the femoral head related to endoplasmic reticulum stress pathways were included, and the redundant and old articles or Meta-analysis were excluded. RESULTS AND CONCLUSION: Endoplasmic reticulum stress regulates autophagy mainly through PERK/eIF2α pathway, IRE1-TRAF2-JNK pathway and regulation of intracellular Ca2+ concentration. Endoplasmic reticulum stress regulates apoptosis by activating C/EBP homologous protein of PERK/eIF2α pathway, IRE1α- ASK1-JNK pathway, IRE1α-XBP1-CHOP pathway and Caspase-12 pathway. In mild endoplasmic reticulum stress, the endoplasmic reticulum can initiate autophagy by activating unfolded protein response pathway to restore endoplasmic reticulum homeostasis and promote cell survival. Endoplasmic reticulum stress stimulation that is too strong and persistent will over-induce autophagy or activate apoptosis pathway to cause cell death. Endoplasmic reticulum stress can participate in the regulation of autophagy or apoptosis through a variety of signal pathways; there is a complex interaction between autophagy and apoptosis. Endoplasmic reticulum stress is involved in the regulation of programmed death of osteocytes and osteoblasts in the pathogenesis of steroidinduced avascular necrosis of the femoral head, but the specific mechanism is not clear.

The flow-induced vibration of cantilevered fluid-conveying pipes with elastic support was analyzed by differential transformation method ( DTM ). Firstly, the motion equation was non-dimensionalized, then, the recurrence relation among each derivative was derived by DTM. Furthermore, the former four dimensionless frequencies and the general expression for mode shapes were obtained without consideration of fluid flow. On this basis, the relationship between frequency and flow velocity, elastic coefficient was worked out, and the critical velocity and stability condition were investigated simultaneously. DTM was verified to be of high accuracy and practicability by comparison and analysis. Besides, DTM could be referred when support format for pipes are designed. [ABSTRACT FROM AUTHOR]

The numerical stability of stable heat transfer along moving fluid-structure interface was investigated. Taking the Dirichlet-Robin conditions into account， the interface movement was designated by velocity. The most common configurations (finite volume method for fluid domain and finite element method for solid domain) were used to discretize the fluid-structure system and perform numerical computation， respectively. Great emphasis was put on stability of numerical treatments when the interface moving with the adoption of the Goudonov-Ryabenkii theory normal mode analysis method. An optimal curve composed of coupling coefficient and velocity was finally obtained， which verified that the discrete system would reach fastest convergence rate and definite stability if the values of coupling coefficient and velocity come from this curve. These conclusions will provide a reference for designers to select reasonable parameters during numerical simulation. [ABSTRACT FROM AUTHOR]
