A practical technique of reverse orbicularis oculi muscle resection with preserved subcutaneous capillary network for double eyelid blepharoplasty

引用

Chinese Journal of Plastic and Reconstructive Surgery 2022年第3期4卷 115-118页

作者： Bin Yang jinhua xu Enjing Wang Xinghai Gao Lun Liu Bin xu Department of Plastic Surgery Yangzhong People’s HospitalYangzhou University School of MedicineYangzhong 212200ZhenjiangJiangsuChina

Background: Traditional full-incision double eyelid blepharoplasty has several significant disadvantages, including slow recovery and bilateral asymmetry, which results in high rates of patient dissatisfaction. These problems can be minimized using improved surgical techniques aimed at reducing tissue damage and bleeding, decreasing operation time, and especially at protecting the subcutaneous capillary network during the operation. We therefore aimed to guard the capillary network and reduce intraoperative bleeding using the practical technique of reverse orbicularis oculi muscle ***: Fifty cases of double eyelid blepharoplasty with traditional full-incision(group A) and 61 cases of reverse double eyelid blepharoplasty with a preserved capillary network(group B) were divided into two groups from October 1 to December 31, 2021 and from March 1 to May 31, 2022, respectively. The orbicularis oculi muscle was removed reversely from the front of the tarsal plate using double eyelid blepharoplasty, and the muscular membrane and subcutaneous capillary network were preserved. The operation time recorded in previous medical records was checked and compared with that of our novel technique. The recovery of double eyelid blepharoplasty was determined at 1, 4, and 12 weeks after the operation and patient satisfaction was also compared with that in previous medical records of patients in group ***: The reverse double eyelid blepharoplasty procedure was less complicated and easier to control than the traditional full-incision double eyelid blepharoplasty methodology. The average operation time of the double eyelid blepharoplasty cases with traditional full-incision was significantly greater than that of the cases of reverse double eyelid blepharoplasty with the capillary network preserved(45.68 ± 5.27 min and 31.11 ± 5.58 min,respectively;t=14.018 9, P=0.000 0). Patient satisfaction was 42% and 78.69%, respectively, at 1 week postoperation(χ~2=15.724 8, P=0.0

Robust, ultra-flexible, and multifunctional MXene-basedelectromagnetic interference (EMI) shielding nanocomposite filmsexhibit enormous potential for applications in artificial intelligence,wireless telecommunication, and portable/wearable electronic *** this work, a nacre-inspired multifunctional heterocyclic aramid(HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite paper withlarge-scale, high strength, super toughness, and excellent tolerance tocomplex conditions is fabricated through the strategy of HA/MXenehydrogel template-assisted in-situ assembly of PPy. Benefiting from the"brick-and-mortar" layered structure and the strong hydrogen-bondinginteractions among MXene, HA, and PPy, the paper exhibits remarkable mechanical performances, including high tensile strength (309.7 MPa),outstanding toughness (57.6 MJ m−3), exceptional foldability, and structural stability against ultrasonication. By using the template effect ofHA/MXene to guide the assembly of conductive polymers, the synthesized paper obtains excellent electronic conductivity. More importantly,the highly continuous conductive path enables the nanocomposite paper to achieve a splendid EMI shielding effectiveness (EMI SE) of 54.1 dBat an ultra-thin thickness (25.4 μm) and a high specific EMI SE of 17,204.7 dB cm2g−1. In addition, the papers also have excellent applicationsin electromagnetic protection, electro-/photothermal de-icing, thermal therapy, and fire safety. These findings broaden the ideas for developinghigh-performance and multifunctional MXene-based films with enormous application potential in EMI shielding and thermal management.

本文构建理论模型分析了反收购强度对公司控制权防御的影响与最优反收购强度的选择,并将大股东掏空行为纳入分析框架.首先,在三种不同的反收购决策权归属的情况下,分别考察目标公司的中小股东,代表大股东利益的管理层以及潜在主并企业的三方博弈行为.其次,构建了反收购强度如何影响公司控制权防御的理论模型.最后进行了数值分析,综合阐述了反收购强度对潜在主并企业的出价及目标公司并购概率的影响.主要研究结果表明:1)除开传统文献中提出的谈判收益假说与管理层堑壕假说,反收购条款的控制权防御作用同时也受到目标公司反收购决策主体的影响.2)在三种不同的反收购决策权归属的情况下,主并企业的最优出价均随着反收购强度增加而升高,且随着大股东持股比例增高,最优出价也将会进一步提升.3)反收购强度和反收购决策权的归属是影响并购概率的两种重要因素,当明确反收购归属权时,并购概率随着反收购强度的加强而下降;当目标公司改变反收购归属权时,即使反收购强度增大,并购概率也可能会上升.
