| 1 | Combination of ablative fractional carbon dioxide laser and platelet-rich plasma treatment to improve hypertrophic scars:a retrospective clinical observational study显示文摘Background:Hypertrophic scars are one of the main complications that affect the quality of life of patients after burns.Many methods have been shown to be effective in the treatment of hypertrophic scars,such as ablative fractional CO_(2) laser(AFCL)and platelet-rich plasma(PRP).However,there are few studies on the effect of the combined application of these measures.The purpose of this study was to explore the therapeutic effect of AFCL combined with PRP on hypertrophic burn scars.Methods:A retrospective clinical observation study was conducted on 50 patients with hypertrophic burn scars.The AFCL+PRP group included 31 patients who received AFCL combined with PRP treatment;the AFCL group included 19 patients who received AFCL treatment only.The University of North Carolina 4P Scar Scale(UNC4P)and the Vancouver Scar Scale(VSS)scores that were collected before each treatment were used as indicators of the effectiveness of the previous treatment.The scores recorded at the second,fourth and seventh months were analysed.Results:The demographic data of the 2 groups were not significantly different.Before treatment,therewas no difference in the UNC4P and VSS scores between the 2 groups.Therewas a significant decline in the UNC4P and VSS total scores over 6 months in both groups(p<0.05)and scores in the 2 groups were comparable after 3 and 6 months(p<0.05).UNC4P scores in the AFCL+PRP group decreased from a mean of 8.26 to 2.61(p<0.05)with a concomitant drop in VSS scores from a mean of 11.74 to 6.06(p<0.01).In the AFCL group UNC4P and VSS scores decreased from 7.68 to 4.63(p<0.05)and from 10.89 to 8.16(p<0.05),respectively.The sub-items of these 2 assessments were analysed and the results suggest that AFCL combined with PRP can comprehensively improve scarring.Conclusions:This study shows that PRP is an effective adjunct for AFCL in the treatment of hypertrophic burn scars and that the combination of PRP and AFCL proved to be more useful than AFCL alone.This combination may be a new and effective clinical practice for the treatment of scars.However,larger and higher-level clinical studies are still needed to determine its efficacy and possible mechanisms. | Zhanzhan Dai Xiaozhen Lou Tuo Shen Yu Sun Yongqiang Xiao Xingfeng Zheng Xuexin Wang Yu Peng Yukun Guo Yibin Guo Jiannan Wen He Fang Bing Ma Zhaofan Xia | 2021 | Burns & Trauma2021，9，1： | 4 |
| 2 | A novel wet-spinning method of manufacturing continuous bio-inspired composites based on graphene oxide and sodium alginate显示文摘珠母贝是小、强壮、生硬、坚韧的材料,它为材料设计使它成为一个 mimicking 目标。由各种各样的方法模仿珠母贝的许多尝试与优秀性质导致了人工的珠母贝的合成。然而,制造过程由于顺序的步很勤劳、费时间,并且仅仅限制大小的材料能被获得。因此,与一致分层的结构启用高效的人工的珠母贝的可伸缩的生产的一个新奇图案着急地被需要。我们开发了一种新奇湿旋转的集会技术很快生产连续 nacremimic graphene 氧化物(去,砖) 钠 alginate (SA,臼) 有优秀机械性质的电影和纤维。在高集中, GO-SA 混合物自发地由于模板效果生产了液体晶体(LC ) 去,并且连续,长像珠母贝的 GO-SA 拍摄的 6 m 从获得的 GO-SA 液体是湿纺纱的水晶(LC ) 以多达 1.5 m/min 的速度做。装配宏观的 GO-SA composites 从 LC 阶段继承了 GO 表的排列,并且他们的机械性质被联合试验性计算的研究调查。张力的测试表明最大的力量() 并且当最大值珍视时,获得的电影的幼仔模量(E) 到达了 239.6 MPa 和 22.4 GPa,为纤维的 E 分别地是 784.9 MPa 和 58 GPa。描述的湿旋转的集会方法为高效的连续人工的珠母贝的大规模、快的生产是适用的。 | Xiaozhen Hu Sangeetha Rajendran Yuansi Yao Zheng Liu Karthikeyan Gopalsamy Li Peng Chao Gao | 2016 | Nano Research2016，9，3： | 4 |

| 4 | Study on Drying Edible Soya-bean Oil Using Solar Energy显示文摘Soya-bean oil (bean dregs) was dried in a solar energy drying system. Characteristics of the process were measured and the corresponding curves were done. The practicability of this process has been discussed. The results showed that the solar drying system could completely meet technological requirements of drying soy-bean oil, and it was feasible in technology to use the solar drying system to dry the vegetable oil. | LIU Shengyong LIU Peng SHEN Xiaozhen XU Guizhuan SU Chaojie CAI Xianjie | 2010 | Journal of Northeast Agricultural University(English Edition)2010，17，4： | 1 |

| 7 | Fixed-Time Adaptive Time-Varying Matrix Projective Synchronization of Time-Delayed Chaotic Systems with Different Dimensions显示文摘This paper deals with the fixed-time adaptive time-varying matrix projective synchronization(ATVMPS)of different dimensional chaotic systems(DDCSs)with time delays and unknown parameters.Firstly,to estimate the unknown parameters,adaptive parameter updated laws are designed.Secondly,to realize the fixed-time ATVMPS of the time-delayed DDCSs,an adaptive delay-unrelated controller is designed,where time delays of chaotic systems are known or unknown.Thirdly,some simple fixed-time ATVMPS criteria are deduced,and the rigorous proof is provided by employing the inequality technique and Lyapunov theory.Furthermore,the settling time of fixed-time synchronization(Fix-TS)is obtained,which depends only on controller parameters and system parameters and is independent of the system’s initial states.Finally,simulation examples are presented to validate the theoretical analysis. | Peng Zheng Xiaozhen Guo Guoguang Wen | 2022 | Computer Modeling in Engineering & Sciences2022，，6： | 0 |
