Objective To study the two-phase flow dynamics distribution and red blood cell distribution under the fluid-solid coupling interaction in left coronary artery at the typical time point within one cardiac cycle,and to investigate the formation and development mechanisms of left coronary artery atherosclerotic plaque Methods The blood was regarded as a two-phase fluid.Based on fluid-solid interaction between blood and vascular wall,the computational fluid dynamics method was used to make the transient numerical simulation of two-phase flow in the left coronary artery under fluid-solid interaction;the distribution of blood flow in the left coronary artery at the typical time point within one cardiac cycle was studied,the relationship between hemodynamic parameters and the formation of atherosclerotic plaque was analyzed.Results A lowspeed eddy zone existed in an area between the distal segment of circumferential branch and the proximal outside of blunt-edge branch of the left coronary artery,where both internal wall shear stress and red blood cell volume fraction were very small and the blood flow pattern was very complicated.Conclusion At the lowspeed eddy zone that carries small wall shear stress,the lipid concentration polarization and macromolecular material deposition are easy to be produced.The area that has less red blood cells is liable to develop hypoxia,resulting in increased vascular wall permeability and intimal injury,which will activate the immune system,causing lipid accumulation in vascular wall and intimal hyperplasia and,thus,to induce the formation of atherosclerotic plaque.(J Intervent Radiol,2017,26:253-257)

Background and purpose: Previous studies have confirmed that the expression of leucine-rich repeat-containing 3B (CLRRC3B) was significantly decreased in different human cancers, which was also associated with the migration and invasion of cancer cells. The aim of this study was to explore the potential mechanism of LRRC3B in the development of esophageal cancer. Methods: The LRRC3B expression was detected in 60 cancer tissues and 60 adjacent non-neoplastic tissues by immunohistochemistry. The mRNA and protein expression of LRRC3B in Eca109 and HEECs were detected using real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot, respectively. Eca109 cells with different treatments were divided into three groups:normal group, negative control group (transfected with pCMV6 plasmid), overexpression LRRC3B group (transfected with pCMV6-LRRC3B plasmid). Transwell assay was used to measure the migration and invasion of Eca109 cells in different groups. The protein levels of E-cadherin, N-cadherin, Vimentin and p-Akt were determined by Western blot. Results: The expression of LRRC3B in esophageal cancer tissues was lower than that of non-cancerous tissues, as well as the expression of LRRC3B in Eca109 was decreased compared with that of normal esophageal epithelial cell line HEEC. Overexpression of LRRC3B significantly inhibited Eca109 cells migration and invasion, upregulated the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin. Moreover, overexpression of LRRC3B significantly inhibited the phosphorylation of Akt in Eca109 cells. Conclusion: The expression of LRRC3B was decreased in esophageal cancer. Overexpression of LRRC3B can efficiently inhibit the EMT progression in esophageal cancer cells by suppressing PI3K/Akt signaling pathway.

Objective To study the pain controlling effects of non-pharmaceutical interventions in neonatal intensive care unit (NICU) setting. Methods Infants who received radial artery puncture were assigned into control group, non-nutritive sucking (NNS) group and NNS plus glucose (NNS + GS) group according to their admission sequences. Each group contained 20 patients. Heart rate ( HR), respiratory rate (RR) and oxygen saturation (SpO2 ) before and after the procedure were monitored using Multi-Parameter Monitor ECG. Neonatal pain was evaluated using the preterm infant pain profile (PIPP). Results Among all three groups, after radial artery puncture, HR and RR were significantly increased, and SpO2 was significantly decreased (P < 0. 01). HR, RR and SpO2 variations in NNS group and NNS + GS group were less significant than the control group (P < 0. 05), and recovered to baseline more quickly. During the radial artery puncture, PIPP scores of infants in NNS and NNS + GS group were significantly lower than the control group (P < 0. 01), with NNS + GS group lower than NNS group (P <0. 05). Conclusions HR, RR and SpO2 can be used as physiological indicators of neonatal pain. PIPP score is simple and practical to be used in NICU setting. Both NNS and NNS + GS can partially relieve neonatal pain, and NNS + GS works better.
