Nursing Care and Causative Analysis of Grade IV Capsular Contracture Following Breast Cancer Expander Implantation

Advances in Breast Cancer Research 2024年第1期13卷 1-9页

作者： Rong Chen Nan zhang huiting zhang State Key Laboratory of Oncology in South China Collaborative Innovation Center for Cancer Medicine Department of Breast Cancer Sun Yat-sen University Cancer Hospital Guangzhou China

Objective: By observing the treatment and nursing care of a patient with Grade IV capsular contracture following breast cancer expander implantation and subsequent Stage II reconstruction, we aim to analyze the reasons for the formation of capsular contracture after Stage I expander implantation and prevent its recurrence following Stage II reconstruction. Methods: In May 2020, the patient noticed an increase in the size of a breast mass. In August, she underwent AC-THP neoadjuvant chemotherapy, followed by a “right breast-conserving nipple-areolar subglandular excision + right axillary lymph node dissection + expander implantation” surgery in November 2020. Radiation therapy began in January 2021. During radiation therapy, the patient experienced severe breast hardening, distortion, tenderness, and was diagnosed with Grade IV capsular contracture. To relieve the capsular contracture, the patient underwent a “contracted capsule incision and release procedure + removal of the right breast expander + right breast implantation” surgery in July 2021. Postoperatively, measures were taken to prevent incision infection, emphasizing aseptic techniques, ensuring smooth negative pressure drainage, reducing skin flap tension, monitoring skin flap blood supply, actively preventing subcutaneous effusion and hematoma, and applying appropriate compression dressings. Results: The patient was discharged after the removal of the drainage tube. During the postoperative follow-up at 3 and 6 months, there was no recurrence of capsular contracture, and the breast appeared full, upright, and relatively soft. There were no complications such as hematoma, infection, breast implant rupture, breast sagging, or displacement. The patient had a good outcome without additional financial or surgical burdens. Conclusion: The occurrence of Grade IV capsular contracture in the patient is generally related to infection after Stage I expander implantation, improper compression dressing, excessive salin

Journal of Cancer Therapy 2024年第4期15卷 201-211页

作者： Qiaoling Zhong Huizhen zhang Liping zhang Qinghua Luo huiting zhang Feng Liu Hailin Tang Na Li Lijuan zhang State Key Laboratory of Oncology in South China Sun Yat-sen University Cancer Center Guangzhou China

BACKGROUND: Secondary lymphedema is one of the common complications after malignant tumor surgery. It is a chronic and complex disease. Once lymphedema occurs, there will be discomfort such as limb swelling, pain, numbness and tension, which will eventually lead to changes in the appearance of the affected limb and will seriously affect the quality of life and require lifelong treatment and psychosocial support. This study investigated the current situation of stigma and alexithymia in patients with lymphedema, and discussed the impact of alexithymia on stigma in patients with lymphedema. AIMS: To understand the current situation of stigma and alexithymia in patients with lymphedema, and to analyze the influence of alexithymia on stigma. METHODS: 195 patients with lymphedema in a hospital were selected by convenient sampling. General information questionnaire, Toronto Alexithymia Scale and social impact scale were used to investigate respectively, to study the general situation, stigma and alexithymia of the respondents. RESULTS: The results showed that the total score of stigma in 195 patients with lymphedema was (60.36 ± 11.08), and the total score of alexithymia was (56.53 ± 8.43). Multiple linear regression analysis showed that alexithymia and family relationship were the influencing factors of stigma in patients with lymphedema. CONCLUSIONS: The patients with lymphedema have obvious stigma, and alexithymia and family relationship are the influencing factors.

Journal of Cosmetics, Dermatological Sciences and Applications 2024年第2期14卷 188-199页

作者： Qiaoling Zhong Feng Liu huiting zhang Liping zhang Jinlan Li Lijuan zhang Na Li Qinghua Luo Cancer Prevention and Treatment Center Affiliated to Sun Yat-Sen University State Key Laboratory of South China Oncology Guangzhou China

Objective: To explore the pre-treatment and efficacy analysis of comprehensive anti-inflammatory treatment for lymphedema in patients with irritating contact dermatitis. Method: Convenience sampling method was used to observe the skin of 160 patients with upper limb lymphedema admitted to the lymphedema outpatient department of our hospital. They were divided into an observation group (80 cases) and a control group (80 cases), and both groups received a course of comprehensive anti-inflammatory treatment (20 treatments). The control group received routine skin care;On the basis of the control group, the observation group received pre-treatment of the affected limb skin: Laofuzi herbal ointment was applied externally to the prone areas of irritating contact dermatitis (such as the upper arm, inner forearm, and cubital fossa). Result: The incidence of irritating contact dermatitis in the observation group was significantly lower than that in the control group (P 0.05). Patients in the observation group felt significantly better in terms of comfort, skin moisture, and itching relief after being wrapped with low elasticity bandages than those in the control group (P Conclusion: Preventive treatment can effectively reduce the incidence of irritating contact dermatitis, prolong the time of stress treatment, thereby increasing efficacy and improving patient compliance.

CSEE Journal of Power and Energy Systems 2023年第6期9卷 2188-2203页

作者： Xu zhang huiting zhang Dongying zhang Yixian Wang Ruiting Ding Yuchuan Zheng Yongxu zhang the School of Electrical&Electronic Engineering North China Electric Power UniversityBeijing 102206China

Existing power grid fault diagnosis methods relyon manual experience to design diagnosis models, lack theability to extract fault knowledge, and are difficult to adaptto complex and changeable engineering sites. Considering thissituation, this paper proposes a power grid fault diagnosismethod based on a deep pyramid convolutional neural networkfor the alarm information set. This approach uses the deepfeature extraction ability of the network to extract fault featureknowledge from alarm information texts and achieve end-to-endfault classification and fault device identification. First, a deeppyramid convolutional neural network model for extracting theoverall characteristics of fault events is constructed to identifyfault types. Second, a deep pyramidal convolutional neuralnetwork model for alarm information text is constructed, thetext description characteristics associated with alarm informationtexts are extracted, the key information corresponding to faultsin the alarm information set is identified, and suspicious faultydevices are selected. Then, a fault device identification strategythat integrates fault-type and time sequence priorities is proposedto identify faulty devices. Finally, the actual fault cases and thefault cases generated by the simulation are studied, and theresults verify the effectiveness and practicability of the methodpresented in this paper.

位于青藏高原东部的川西构造带分布有高温地热资源,但同时也是地震活动多发区。为探究地热流体对断层岩石的腐蚀损伤,本文对川西金河-箐河断裂带上的糜棱岩开展100~350℃亚临界水环境(100~374℃,饱和蒸汽压0.1~22.1MPa)下的水-岩相互作用试验,通过电感耦合等离子体质谱仪(ICP-MS)和低温氮气吸附实验(LTNA)分析了反应后溶液成分和岩石孔隙结构随温度的变化规律。研究结果表明,川西糜棱岩Si的溶解速率在100~350℃范围内与水-岩作用温度呈正相关,350℃时溶解速率是100℃的10.97倍,而Na、Ca、K、Al和Mg等金属元素的溶解速率远低于Si。在长期水-热腐蚀下,糜棱岩Si元素的大量析出和硅酸盐矿物的分解会破坏岩石的孔隙结构,伴随微孔、中孔的萌生和发育,糜棱岩总孔体积由25℃时的0.00541cm^(3)·g^(-1)升高到350℃的0.00659cm^(3)·g^(-1),且比表面积随热处理温度的升高呈上升趋势,这会加强水与糜棱岩的接触,从而导致岩石的进一步劣化。本项研究结果为探究糜棱岩在亚临界水环境下的水-热腐蚀机制和地热流体影响断层稳定性提供了一定的见解。
