| 1 | A modified scar model with controlled tension on secondary wound healing in mice显示文摘Pathological scars might cause a distorted appearance and restricted mobility,and the study of scar pathophysiology has been hindered by the absence of a reliable model.In this study,we introduce a model with a modified device to induce controlled tension on a wound healing by secondary intention to overcome the shortcomings of the model generated by Aarabi et al.We investigated and recommend an induction of 0.1 N/mm^(2) tension on day 7 for 14 days to mimic the characteristics of human scars.A 3.5-fold increase in scar tissue and a 2-fold increase in collagen production were induced by the modified model.Histologically,the modified method increased scar thickness.However,no significant difference was found in cell density between the two groups.This modified procedure significantly increased scar tissue,which could be used for further cellular and biomolecular research.The mechanical force applied to the wound became measurable and controllable.This method is more convenient for researchers to observe in realtime and for providing timely adjustments of the tension used in this modified model. | Zi Wang Xin Huang Tao Zan Qingfeng Li Haizhou Li | 2020 | Burns & Trauma2020，8，1： | 2 |

| 8 | Modification Mechanism and Uniaxial Fatigue Performances of A356.2 Alloy Treated by Al-Sr-La Composite Refinement-Modification Agent显示文摘Modification mechanism and uniaxial fatigue properties of A356.2 alloy treated by Al-6Sr-7La and traditional Al-5Ti-1B/Al-10Sr(hereinafter refers to traditional treated alloy) were investigated by constant stress amplitude method. Microstructure, dislocation and Si twinning of the alloys were studied by thermal analysis, scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The results showed that Al-6Sr-7La possesses better refining and modification effect than Al-5Ti-1B/Al-10Sr. Meanwhile, fatigue properties of the alloy treated by Al-6Sr-7La are higher than traditional treated alloy, and this is mainly owing to that Al-6Sr-7La treated alloy has more twins in eutectic Si and lower twin spacing. In addition, higher density of nanophases formed on twin faces and La-rich clusters appear at multiple twin intersections. Stacking faults and entrapped nanophases appeared on growing Si twin faces. Impurity induced twinning(IIT) mechanism and twin plane re-entrant edge(TPRE) mechanism are valid for eutectic Si which are important for mechanical optimization of A356.2 alloy. | Liang Chang Qingfeng Zhao Xingchuan Xia Yuming Ding Binxu Guo Jian Ding Ying Tang Zan Zhang Chong Li Xiaomian Sun Junjie Guo Kaihong Song Yongchang Liu | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，6： | 0 |
| 9 | Fine-needle aspiration for periprosthetic fluid removal after implantation of a remote internal-port tissue expander显示文摘Background:Use of internal filling ports in tissue expander–based reconstructions are advantageous because of easier self-care,lower infection rates,and fewer instances of capsule formation.The appearance of periprosthetic fluid accumulation after internal-port tissue expander implantation is a common complication that warrants treatment.In this study,we introduced a noninvasive method using fine-needle aspiration(FNA)to remove fluids accumulated after implantation of a remote internal-port tissue expander.Methods:In this study,245 patients who underwent implantation of remote internal-port tissue expanders in our hospital from July 1,2012,to July 1,2019,were included and divided into two groups.In the control group,patients underwent tissue expander implantation before July 1,2016,and large quantities of fluids were removed with surgical aspiration procedures in most cases.In the FNA group,the patients underwent implantation after July 1,2016,and large quantities of fluids were removed first with the FNA procedure.Patients’demographic data,indications for FNA application,and related complications were collected and analyzed.Results:Overall,395 expanders were placed in 245 patients.Postoperative management was similar in both groups.Fluids were managed with 23 expanders in the control group and with 31 expanders in the FNA group.There was no difference in the fluid aspiration rate between the two groups.The surgical aspiration rate was 11.1%(23/208)in the control group.The success rate of FNA was 90.3%(28/31).In the FNA group,the surgical aspiration rate was 1.6%(3/187),which was significantly lower than that in the control group.There were no significant differences in complications between the two groups.Conclusion:FNA can be used for periprosthetic fluid removal after the implantation of a remote internal-port tissue expander in most cases.This method is more convenient and safer than surgical aspiration for the postoperative management of internal-port tissue expander implantation. | Xifeng Lin Shuchen Gu Yashan Gao Hainan Zhu Bin Gu Feng Xie Qingfeng Li Tao Zan Haizhou Li | 2021 | Chinese Journal Of Plastic and Reconstructive Surgery2021，3，3： | 0 |
