| 5 | Design and Performance Study of an Ultrasonic Bone Scalpel with Composite Horn Structure显示文摘The ultrasonic bone scalpel was often used in all kinds of clinical orthopedic surgery as a new type of medical instrument.Based on the working theory of the ultrasonic bone scalpel and combined with the design method of a quarter wavelength transducer and horn,this study proposed an optimization design method for the ultrasonic bone scalpel with a composite horn structure.The structure of the ultrasonic bone scalpel was simplified,and its length was shortened.Finite element analysis,modal analysis,and harmonic response analysis were used to optimize the design of the ultrasonic bone scalpel.The performance of the ultrasonic bone scalpel was explored through impedance analysis,amplitude measurement,temperature measurement,and cutting tests,and the feasibility of the design was verified through torque analysis.The results showed that when the torque force was 4.0 N,the resonance frequency of the ultrasonic bone scalpel was 30,540 Hz,and the maximum amplitude of the ultrasonic bone scalpel could reach 62μm.After spray cooling,the maximum surface temperature of the rear end cover was reduced from 51.8 to 36.3℃,the maximum surface temperature of the composite horn was reduced from 71 to 45.3℃,and the maximum surface temperature of the cutter head was reduced from 101 to 46.1℃,demonstrating a good cooling effect.Under 89 Voltage,the optimal cutting force for cutting chicken leg bones was 0.1 N,the optimal cutting force for cutting pork ribs was 0.3 N,and the cutting process showed tissue selectivity. | Jieping Wu Yong Yang Zhao Yang Cong Chen Shuai Huang | 2023 | Nanomanufacturing and Metrology2023，6，1： | 0 |
| 6 | Construction and optimization of a base editor based on the MS2 system显示文摘Background:Catalytic defect Cas9‐cytosine deaminase fusion is widely used in base editing.The Multiple copy numbers of the MS2 binding site(MBS)can recruit multiple MS2 coat proteins(MCPs),which are usually applied to amplify signals.Our study aimed to apply the MS2 signal amplification system to the base editing system in order to achieve simultaneous mutations of multiple bases at the target genome site.Methods:Multiple copy numbers of the MS2 were ligated to the 3′‐end of sgRNA,and MCP was fused to the 5′‐end of cytosine deaminases.The MS2 was recognized by MCP to recruit cytosine deaminase for base substitutions(C‐T)at the target site.Different Cas9 variants,different cytosine deaminases and different copy numbers of MS2 were tested in this system,and the different versions of base editors were compared by editing efficiency and window.Results:In this study,dCas9,nCas9(D10A)and nCas9(H840A)were used.Among these 3 Cas9 variants,dCas9 exhibited higher base mutation efficiency.Two cytosine deaminases were then applied and the efficiency of rAPOBEC1 deaminase was found to be higher than AID.We also increased the copy numbers of MS2 linked to sgRNA from 2 to 12.Disappointingly,the sgRNA‐12x MS2 did not improve the editing efficiency or increase the editing window.Conclusion:An optimal version of base editor based on the MS2 system,MS2‐BErAPOBEC1(sgRNA‐2x MS2,MCP‐rAPOBEC1 and dCas9),was obtained.This tool can simultaneously mutate multiple bases at the target site,providing a new approach for the study of genome functions. | Shuzhen Zhang Songjie Feng Wen Jiang Xingxu Huang Jieping Chen | 2019 | Animal Models and Experimental Medicine2019，2，3： | 0 |
| 7 | Overcoming adaptive resistance in AML by synergistically targeting FOXO3A-GNG7-mTOR axis with FOXO3A inhibitor Gardenoside and rapamycin显示文摘Therapeutic targeting FOxO3A(a forkhead transcription factor)represents a prom-ising strategy to suppress acute myeloid leukemia(AML).However,the effective inhibitors that target FOXO3A are lacking and the adaptive response signaling weakens the cytotoxic effect of FOxO3A depletion on AML cells.Here,we show that FOxO3A deficiency induces a compensa-tory response involved in the reactive activation of mTOR that leads to signaling rebound and adaptive resistance.Mitochondrial metabolism acts downstream of mTOR to provoke activa-tion of JNK/c-JUN via reactive oxygen species(ROS).At the molecular level,FOXO3A directly binds to the promoter of G protein gamma subunit 7(GNG7)and preserves its expression,while GNG7 interacts with mTOR and restricts phosphorylated activation of mTOR.Consequently,combinatorial inhibition of FOXO3A and mTOR show a synergistic cytotoxic effect on AML cells and prolongs survival in a mouse model of AML.Through a structure-based virtual screening,we report one potent small-molecule FOxO3A inhibitor(Gardenoside)that exhibits a strong effect of anti-FOXO3A DNA binding.Gardenoside synergizes with rapamycin to substantially reduce tumor burden and extend survival in AML patient-derived xenograft model.These results demonstrate that mTOR can mediate adaptive resistance to FOxO3A inhibition and validate a combinatorial approach for treating AML. | Zhe Chen Qian Guo Shichen Huang Lei Li Feng Wu Zhilong Liu Zhigang Li Tao Chen Guanbin Song Shuangnian Xu Jieping Chen Yu Hou | 2024 | Genes & Diseases2024，11，1： | 0 |
