| 1 | Biomechanical analysis of the computer-assisted internal fixation of a femoral neck fracture显示文摘The number and spatial configuration of the screws will affect the stability and prognosis of the fractures.In our study,we assessed the biomechanical effects of the double-head cannulated compression screw(DhCCS)and ordinary cannulated compression screw(OCCS)for the treatment of femoral neck fractures by using computer finite element analysis.The original digital imaging and communications in medicine(DICOM)data of a proximal femur were imported into Materialise’s interactive medical image control system(MIMICS)software for modeling.Both DhCCS and OCCS 3D-models were obtained by using the 3D scan technique.Using the fracture model and internal fixation assembly model with an inverted triangle,two horizontal and vertical distribution were established in UG software.Next,the displacement and stress distribution were calculated in ANSYS software.The displacement value of the femoral head in the DhCCS group was smaller than that in the OCCS group,and the displacement value in the two horizontal groups was smaller than that in the vertical group.The stress distribution in the DhCCS group was concentrated on the screw rod at the fracture block and thread end,while only at the fracture block in the OCCS group.The stress in the horizontal group was more dispersed on the screws than that in the vertical group.DhCCS has reliable stability for the fixation of femoral neck fractures and applied in the clinical work and 2 horizontal fixation can be used when two screws are selected. | Hui Lu Hongquan Shen Shuqing Zhou Weidong Ni Dianming Jiang | 2020 | Genes & Diseases2020，7，3： | 3 |
| 2 | Distribution of δ^(34)S and δ^(18)O in SO_4^(2-) in Groundwater from the Ordos Cretaceous Groundwater Basin and Geological Implications显示文摘The Ordos Cretaceous Groundwater Basin,located in an arid-semiarid area in northwestern China,is a large-style groundwater basin.SO_4^(2-) is one of the major harmful components in groundwater.Dissolved SO_4^(2-) concentrations,andδ^(34)S-SO_4^(2-) andδ^(18)O-SO_4^(2-) in groundwater from 14 boreholes and in gypsum from aquifer were analyzed.Results show that SO_4^(2-) in shallow groundwaters originates from precipitation,sulfide oxidation,and dissolution of stratum sulphate,with a big range ofδ^(34)S values,from-10.7‰to 9.2‰,and addition of SO_4^(2-) in deep groundwater results from dissolution of stratum sulphate,with biggerδ^(34)S values,from 7.8‰to 18.5‰,compared with those in shallow groundwater.This research also indicates that three types of sulphate are present in the strata,and characterized by highδ^(34)S values and highδ^(18)O values-style,highδ^(34)S values and middleδ^(18)O valuesstyle, middleδ^(34)S values and lowδ^(18)O values-style,respectively.Theδ^(34)S-SO_4^(2-) andδ^(18)O-SO_4^(2-) in groundwater have a good perspective for application in distinguishing different groundwater systems and determining groundwater circulation and evolution in this area. | YANG Yuncheng SHEN Zhaoli WEN Dongguang HOU Guangcai SHE Hongquan ZHAO Zhenhong WANG Dong LI Jingwen | 2010 | Acta Geologica Sinica(English Edition)2010，84，2： | 3 |
| 3 | Novel fusiform core-shell-MOF derived in tact metal@carb on composite:An efficient cathode catalyst for aqueous and solid-state Zn-air batteries显示文摘Owing to the varied mechanisms of ORR/OER,exploiting cost-effective bifunctional catalysts with robust ORR/OER activities and excellent performances in Zn-air batteries is still a challenge.In this work,the Co/CoO@NSC bifunctional catalyst is obtained by using Zn-MOF@Co-MOF as self-template.The Co/CoO@NSC composite has interconnected porous architecture with in tact metal@carb on structure,exhibiting superior electrocatalytic activities toward ORR and OER that can be comparable with the Pt/C and RuO_(2) catalysts,respectively.The Co/CoO@NSC-based aqueous Zn-air battery achieves a high specific capacity(759.7 mAh/g)and energy density(990.5 Wh/kg),and ultra-long rechargeable property(more than 400 h/1200 cycles).The Co/CoO@NSC-based solid-state Zn-air battery also delivers an excellent performance with a long cycle life(more than 143 h/858 cycles).Most importantly,the newly synthesized and recharged Co/CoO@NSC-based solid-state Zn-air battery can be used to light up a 2 V LED lamp for more than 28 h,demonstrating the superior practicability as rechargeable power source. | Di Zhou Hongquan Fu Jilan Long Kui Shen Xinglong Gou | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |

| 5 | Enhanced genome editing to ameliorate a genetic metabolic liver disease through co-delivery of adeno-associated virus receptor显示文摘Genome editing through adeno-associated viral(AAV) vectors is a promising gene therapy strategy for various diseases,especially genetic disorders. However, homologous recombination(HR) efficiency is extremely low in adult animal models. We assumed that increasing AAV transduction efficiency could increase genome editing activity, especially HR efficiency, for in vivo gene therapy. Firstly, a mouse phenylketonuria(PKU) model carrying a pathogenic R408W mutation in phenylalanine hydroxylase(Pah) was generated. Through co-delivery of the general AAV receptor(AAVR), we found that AAVR could dramatically increase AAV transduction efficiency in vitro and in vivo. Furthermore, co-delivery of SaCas9/sgRNA/donor templates with AAVR via AAV8 vectors increased indel rate over 2-fold and HR rate over 15-fold for the correction of the single mutation in Pah;mice. Moreover, AAVR co-injection successfully increased the site-specific insertion rate of a 1.4 kb Pah cDNA by 11-fold, bringing the HR rate up to 7.3% without detectable global off-target effects. Insertion of Pah cDNA significantly decreased the Phe level and ameliorated PKU symptoms. This study demonstrates a novel strategy to dramatically increase AAV transduction which substantially enhanced in vivo genome editing efficiency in adult animal models, showing clinical potential for both conventional and genome editing-based gene therapy. | Shuming Yin Lie Ma Tingting Shao Mei Zhang Yuting Guan Liren Wang Yaqiang Hu Xi Chen Honghui Han Nan Shen Wenjuan Qiu Hongquan Geng Yongguo Yu Shichang Li Weishi Yu Mingyao Liu Dali Li | 2022 | Science China(Life Sciences)2022，65，4： | 0 |
