The management of chronic wounds presents significant challenges, characterized by a low rate of healing and substantial impairment of patients’ quality of life, while also exerting a considerable strain on healthcare resources. Wound healing is a multifactorial and dynamic process, necessitating close monitoring of wound changes and timely, appropriate interventions. Smart bandage/dressing, an innovative approach born from interdisciplinary research, offers a new generation of wound care. It enables dynamic quantitative monitoring of wound conditions; facilitates transdermal drug release and physical mode therapeutics; and adjusts interventions in real time based on monitoring outcomes. In comparison to traditional wound dressings, smart bandages exhibit attributes such as real-time responsiveness, precision, and convenience. They not only simplify wound management but also enhance patient comfort and compliance, showcasing potential as a safe and effective treatment modality. Smart bandages hold promise for elevating the efficiency of managing chronic wounds, reducing morbidity rates, alleviating the burden of disease, and ultimately improving patients’ quality of life. This paper summarized the recent research progress of smart bandages and provided insights into novel wound care strategies.

Aging has always been a topic that has been widely concerned and discussed. The aging of lower eyelid starts to accelerate after the age of 40 years, which is an important indicator of people’s perceived age, mainly manifested as the emergence of tear trough, palpebromalar groove, eyelid bags, and skin aging. It is of great significance to evaluate the state of lower eyelid completely and objectively for the aging degree of lower eyelid, the formulation of individualized treatment plan and the evaluation of surgical effect. This article reviews the current status and progress of lower eyelid assessment method in recent years.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by hallmark pathological features, including β-amyloid deposition, neurofibrillary tangles formed by hyperphosphorylated tau protein, and chronic neuroinflammation. Recent studies have revealed that the glymphatic-meningeal-cervical lymphatic system plays a pivotal role in intracranial metabolic waste clearance, and its dysfunction may impair the clearance efficiency of β-amyloid and tau proteins. Based on this mechanism, domestic scholars have innovatively proposed lympho-microsurgical reconstruction of the brain-cervical lymphatic drainage pathway, aiming to ameliorate AD pathological progression and cognitive function by enhancing intracranial waste clearance. Through a comprehensive literature review, this article focuses on the theoretical rationale for lympho-microsurgical intervention in AD. While critically evaluating existing surgical approaches and efficacy assessment systems, it further examines the fundamental scientific challenges and clinical translation barriers in directly applying this technique to AD treatment, with the goal of providing theoretical insights and methodological guidance for future research.

To construct a quality control indicators system for Chinese plastic and aesthetic major and lay foundation for medical quality control. National Quality Control Center of Plastic and Aesthetic Major established a working group in February 2023. Guided by the "structure-process-outcome" theory, the working group formulated medical quality control indicators for Plastic and Aesthetic major by learning from relevant indicators of other majors, reviewing literature, discussing in meetings, and combining opinions from quality control experts. The quality control indicators system was finally established by Delphi expert consultation. Delphi survey was 100% of 2 rounds. The authorities of 2 rounds of expert consultation were 0.854 and 0.857. The harmonious coefficients were 0.387 of primary indicators and 0.425 of secondary indicators( The quality control indicators system established in this study for Plastic and Aesthetic major in China has a certain degree of scientificity and rationality, which offers reference for medical quality control of Plastic and Aesthetic major in China. However, this system should be improved and ameliorated in practical application.

To explore the ideal pretarsal shows and morphological characteristics of double eyelids in Chinese populations through a morphometric analysis. This study employed a convenience sampling method to survey Chinese adults who did not reside abroad for an extended period (with cumulative overseas stay of over one year). From November 2023 to May 2024, electronic questionnaires were distributed to collect attractiveness ratings of nine different images (including one image featuring single eyelid and eight images with varying pretarsal shows and morphologies of double eyelids). Stratified comparisons were conducted based on gender, age, occupation, etc., to determine the ideal pretarsal show and morphology of double eyelids. Quantitative analysis was performed on the aesthetic features of the nine images depicting double eyelids to validate and elucidate the survey findings. A total of 493 questionnaires were filled out, and 397 valid questionnaires were included for data analysis after quality control. As for the whole cohort, the images feathering 2 mm double eyelid were deemed to be the most attractive, with the in-fold type scoring (3.72±0.97) points and the out-fold type scoring (3.65±1.04) points. The next was 1 mm, followed by 3 mm, single eyelid, and finally, 4 mm. As for morphology, in-fold type achieved higher scores than out-fold type in images with the same pretarsal show. However, statistically significant differences were only found in ratings for the images with 3 mm and 4 mm double eyelids (all This study validates that the pretarsal show of 2 mm and the presence of either an in-fold or out-fold morphology are considered optimal for double eyelids among Chinese individuals. These findings hold significant implications for the planning of double eyelid surgeries, assessment of surgical outcomes, and evaluation of other periocular procedures associated with double eyelid surgeries.

Improvement of the jawline contour is a key focus in lower face and neck rejuvenation treatments. Achieving a well-defined, smooth jawline is a shared goal for both patients and plastic surgeons. This article reviews recent research on age-related changes of the jawline and evaluation method, offering valuable references for jawline rejuvenation treatments.The jawline's unique anatomical position, coupled with age-related changes, involves dynamic alterations in bone, soft tissue, and skin across multiple layers, making rejuvenation of this area a complex and challenging task. In recent years, advances in imaging technologies such as two-dimensional photography, three-dimensional stereophotogrammetry, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and micro-CT have expanded the understanding of jawline anatomy and provided precise tools for analysis and evaluation.
