| 1 | Multi-center investigation of breast reconstruction after mastectomy from Chinese Society of Breast Surgery:A survey based on 31 tertiary hospitals(CSBrS-004)显示文摘Objective:Multi-center data on the current status and trends of breast reconstruction after mastectomy in China are lacking.Herein,we conducted a cross-sectional survey to investigate the current clinical practice pattern of postmastectomy breast reconstruction among Chinese female patients with breast cancer.Methods:A standardized questionnaire used to collect information on breast reconstruction among females diagnosed with breast cancer was distributed by 31 members of the Chinese Society of Breast Surgery between January 1,2018 and December 31,2018.Information was collected on tumor characteristics,treatment,mesh application,nipple-areola complex(NAC)preservation,postoperative complications,bilateral reconstruction,patient satisfaction and local recurrence.The overall rate of breast reconstruction was assessed,and the characteristics were compared across patient groups with different reconstruction approaches.Results:A total of 1,554 patients underwent breast reconstruction after total mastectomy,with a reconstruction rate of 9.6%.Among them,1,190 were implant-based,and 262 underwent autologous reconstructions,while 102 cases underwent a combination of both.Patients who underwent implant-based reconstruction were younger than those who received autologous reconstruction(40.1±4.6 vs.45.0±5.9,P=0.004).Compared to patients with autologous reconstruction,mesh application(25.5%vs.6.5%),NAC preservation(51.8%vs.40.5%)and reconstruction failure(1.8%vs.0)were more frequently reported among those with implant-based reconstruction.There was no significant difference in general satisfaction across three reconstruction approaches,though patients with autologous reconstruction reported the highest aesthetic satisfaction among the three groups(P=0.044).Conclusions:Implant-based breast reconstruction remains the dominant choice among patients,while autologous reconstruction was associated with higher aesthetic satisfaction.Our multi-center investigation based on the findings of the tertiary hospitals of Chinese Society of Breast Surgery may guide a future series of clinical studies on breast reconstruction in China. | Feng Xu Chuqi Lei Heng Cao Jun Liu Jie Li Hongchuan Jiang Chinese Society of Breast Surgery | 2021 | Chinese Journal of Cancer Research2021，33，1： | 7 |

| 3 | Enhanced mechanical and thermal properties of γ-allyloxymethyl 18-crown-6 and polyimide composites through hydrosilylation crosslinking显示文摘The complexation of y-allyloxymethyl 18-crown-6(AC6) induced inferior mechanical and thermal properties of polyimide(PI) in spite of lowered dielectric constant(k). To solve this puzzle, tetrakis-(di methylsiloxy)-si lane was employed to crosslink the complex of AC6 and PI(AC6-PI) through hydrosilylation reaction. The crosslinked AC6-PI(SiAC-PI) composites possessed excellent mechanical and thermal properties as well as low k. The tensile strength and fracture energy of SiAC-PI were increased by 87% and 716%, and the glass transition temperature and 5% weight loss temperature elevated 14.5 ℃ and 38.8 ℃, respectively, compared with those of AC6-PI. The structure of SiAC-PI was characterized by FTIR spectra, crosslinked density and XRD diffraction patterns. | Chuqi Shi Shumei Liu Yang Li Jianqing Zhao Haohao Huang | 2019 | Chinese Chemical Letters2019，30，3： | 2 |
| 4 | Preparation and thermal-mechanical property evaluation of cellulose insulation paper with differing nano-SiC contents显示文摘Cellulose insulation paper is the main component of oil-paper insulation systems in oilimmersed transformers.However,the poor thermal conductivity and thermal stability of the cellulose can lead to thermal ageing.It is critical to address this issue by improving the performance of cellulose,nano-SiC-modified cellulose models were established by molecular simulation,while nano-SiC composite papersheets were prepared based on the simulation results,and the effects of different contents of nano-SiC on the papersheets were investigated.Macroscopically,doping nano-SiC particles can enhance the thermal stability of cellulose;compared with the unmodified papersheet,the thermal conductivity and tensile strength of the modified papersheets are increased by 44.3%and 42.8%,respectively.The degree of polymerisation of the modified papersheet decreased more slowly than that of the unmodified papersheet under accelerated thermal ageing,showing that the modified papersheet has better anti-ageing properties.Microscopically,with the addition of nano-SiC,the simulations showed that the mean square displacement of the cellulose decreases dramatically and the distribution of the free volume becomes difficult to disperse,which corresponds to the decrease in porosity in the experiments.As a result,this research provides a way for improving the thermal-mechanical properties of cellulose that has practical application significance. | Yiyi Zhang Chuqi Xu Wenchang Wei Yuke Deng Shuangxi Nie Junwei Zha | 2023 | High Voltage2023，8，3： | 0 |
| 5 | FAIRING TECHNIQUE OF THE CURVES AND SURFACES IN INDUSTRIAL STYLING DESIGN显示文摘To many industrial products such as cell phone,family appliance,vehicle,a pretty shape of nice visual effect is indispensable. To fulfill this target,designers are endeavoring to make the curve and surface of the products smooth and continuous during the shape design. Through the analysis and generalization of the present smoothing methods,the energy optimization method which combines the merits of energy method and least squares method together is studied,the target function of energy optimization method is derived,the solution to the target function and steps of curve fairing is introduced,the skills and methods building A-class surface which are based on cloud data measured from 3D scanning are studied,the validity of energy optimization method is verified with the example of the shape design of a mini-EV as well. | HE Yaohua RONG Hui SU Chuqi LI Yujie | 2008 | Chinese Journal of Mechanical Engineering2008，21，1： | 0 |
