In this study, 3DPT showed great clinical feasibility of the treatment of complicated PHFs. The 3D-print PHF model had the ability to clearly display the fracture and thus was useful to determine the fracture classification and the magnitude of fracture injury. It benefited surgeons to gain a better understanding of complicated PHFs, design a most suitable operation plan prior to surgery and facilitate the doctor-patient communication. This therefore enabled the reduction of intraoperative injury and the optimization of surgical outcomes.

Aim: CYP2J3 in myocardium metabolizes arachidonic acid to 4 regioisomeric epoxyeicosatrienoic acids (EETs), which have diverse biological activities in rat heart. In this study we examined whether CYP2J3 was involved in cardioprotective effects of ophiopogonin D (OPD), a steroidal glycoside isolated from Chinese herb Radix ophiopogonis.

Ginkgolide B exerts anti-apoptotic and anti-inflammatory effects on endothelial cells via PXR activation, suggesting that a PXR-mediated endothelial detoxification program may be important for protecting endothelial cells from xeno- and endobiotic-induced injuries.

Neurodegenerative diseases are generally characterized clinically by the selective loss of a distinct subset of neurons and a slow progressive course. Mounting evidence in vivo indicates that large numbers of neurons pass through a long period of injury and dysfunction before the actual death of the cells. Whether these dying neurons can be rescued and return to a normal, functional state is uncertain. In the present study, we explored the reversibility of the neuronal cell death pathway at various stages by monitoring the dynamics of single cells with high-resolution live-cell spinning disk confocal microscopy in an in vitro neuronal cell death model. We exposed differentiated neuronal PC12 cells to ethanol as our cell death model. Results showed that exposure to 5% ethanol for 24 h induced cell death in >70% of the cells. Ethanol treatment for 3 h already induced cellular changes and damage such as reactive oxygen species generation, elevation of intracellular Ca2+ level, phosphatidylserine exposure, nuclear shrinkage, DNA damage, mitochondrial fragmentation and membrane potential loss, and retraction of neurites. These phenomena are often associated with programmed cell death. Importantly, after removing ethanol and further culturing these damaged cells in fresh culture medium, cells recovered from all these cell injuries and generated new neurites. Moreover, results indicated that this recovery was not dependent on exogenous NGF and other growth factors in the cell culture medium. Overall, our results suggest that targeting dying neurons can be an effective therapeutic strategy in neurodegenerative diseases.
