Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Myasthenia gravis is an autoimmune disorder characterized by impaired neuromuscular transmission. Thymectomy is one of the therapeutic options for acetylcholine receptor antibody-positive myasthenia gravis patients. The quality of perioperative care is directly associated with surgical safety and patient outcomes. However, there is currently a lack of specialized nursing consensus or guidelines specifically addressing the care of these patients domestically or internationally. To promote the standardization and normalization of perioperative nursing care for myasthenia gravis patients undergoing thymectomy and to ensure treatment efficacy, a panel of 57 experts from relevant fields was convened. Based on evidence-based medicine and clinical practice experience, discussions were held on various aspects including condition assessment, nutritional support, medication management, and airway care, resulting in a consensus with 18 final recommendations by using the Delphi method through two rounds of expert consultation. This consensus aims to provide a scientific reference for the perioperative nursing care of myasthenia gravis patients undergoing thymectomy.

Ecoflex is a commercial designation for elastomers developed based on the principles of environmental sustainability and flexibility. Various manufacturers offer different types of Ecoflex products with distinct compositions and functions. Among these, the platinum-catalyzed silicone rubber Ecoflex series has demonstrated considerable applicability in various fields of oral medicine due to its excellent flexibility, biocompatibility, stability across a wide temperature range, and tunable mechanical properties. In tissue engineering, it can simulate the mechanical behavior of oral mucosa, and is used in cleft lip surgical training models and preoperative evaluation for temporal bone defect reconstruction. In the field of wearable devices, leveraging its encapsulation protection and flexible characteristics, highly sensitive sensors constructed from Ecoflex can monitor signals such as oral bite force and masticatory muscle activity, thereby aiding in the diagnosis of temporomandibular joint disorders and postoperative evaluation of cleft lip and palate. Moreover, when combined with bio-waste materials, it promotes the functionalization and sustainability of oral wearable devices.In drug delivery systems, its conformability and controlled-release capability address challenges in localized oral drug administration. Designs such as flexible microneedles and temperature-responsive composite systems provide precise solutions for treating periodontitis and oral ulcers. In minimally invasive surgical instruments, its softness enables the development of soft robots and magnetically controlled microfluidic valves, enhancing surgical safety and precision. In the field of oral rehabilitation, Ecoflex soft liner materials, inspired by the suction cup structure of octopus tentacles, improve denture retention. Their low modulus reduces mucosal irritation, ensuring both comfort and durability. Although Ecoflex shows great potential in biomedical applications, it still faces certain challenges, particularly regarding long-term stability after implantation, mechanical fatigue resistance, and microbial colonization, which require further investigation. In the future, with advancements in 3D printing technology, Ecoflex is expected to achieve more precise clinical translation across multiple fields and drive innovation in intelligent biomaterials.

Sleep fragmentation， characterized by disrupted nocturnal sleep，is a core manifestation of chronic insomnia and exhibits a close and complex bidirectional relationship with Alzheimer disease （AD）. On the one hand， sleep fragmentation impairs glymphatic system function， reducing the clearance efficiency of toxic metabolites such as amyloid-beta （Aβ） and tau proteins in the brain interstitial fluid， thereby acting as a promoting factor for AD. Concurrently， sleep disturbances directly dysregulate pathogenic protein dynamics，and chronic sleep deprivation exacerbates neuroinflammation and oxidative stress， worsening the AD pathological environment.On the other hand， inherent AD pathological changes further aggravate sleep fragmentation. Damage to brain regions associated with AD leads to circadian rhythm disruption and reduced non-rapid eye movement （NREM） sleep.Additionally，imbalances in neurotransmitters such as orexin and melatonin during AD progression contribute to the disintegration of the sleep-wake cycle. This review aims to explore the mutual interactions between sleep fragmentation and AD， identify current research gaps， and provide new directions for future studies.

Background/Aims: Dysregulated cholesterol metabolism is a hallmark of hepatocellular carcinoma (HCC) that drives tumor initiation and progression. However, clinical targeting of cholesterol metabolism has yielded limited benefits due to stringent feedback in tumor cells. Identifying a central mediator capable of restoring cholesterol homeostasis within the cell’s intrinsically fine-tuned regulatory framework is urgently needed. Methods: We integrated a proteomic dataset from patients with cholesterol-dysregulated HCC into a global cholesterol metabolic regulatory network to identify potential therapeutic targets for disrupted cholesterol homeostasis. The prognostic significance of the candidate targets was further validated in an independent cohort through immunohistochemistry. Functional and mechanistic studies were conducted in vitro using HCC cell lines and in vivo using mouse models. The pharmacological efficacy of the candidate agent was evaluated in both subcutaneous and orthotopic HCC mouse models. Results: ER lipid raft-associated 1 (ERLIN1), a pivotal regulator of cholesterol metabolism reprogramming, was identified as an independent favorable prognostic indicator in HCC. ERLIN1 constrains HCC progression both in vitro and in vivo by stabilizing the INSIG1–SCAP–SREBP2 axis and maintaining the metabolic balance of intracellular cholesterol. Under hypoxia, impaired factor-inhibiting hypoxia-1-dependent hydroxylation of ASB11 at asparagine residues 90 and 92 enhances ASB11-mediated ERLIN1 degradation. Pharmacological targeting of this axis using zoledronic acid (ZoA) attenuated HCC progression by weakening the ASB11–ERLIN1 interaction and restoring cholesterol homeostasis. Conclusions ERLIN1 represents a druggable metabolic vulnerability in cholesterol-dysregulated HCC. Targeting the ASB11–ERLIN1 axis with the clinically approved ZoA reestablishes cholesterol homeostasis and offers a promising therapeutic strategy to overcome the current limitations of cholesterol-targeted HCC therapies.

Sonodynamic therapy （SDT） applies low-frequency ultrasound to activate sonosensitizers that have accumulated in tumor location， which induces cavitation effects and leads to the in-situ generation of reactive oxygen species （ROS）， thereby achieving precise and efficient tumor treatment. Owing to its advantages such as deep tissue penetration and controllable treatment range， SDT has attracted significant attention and has been widely used in the research on the treatment of various tumors. While conventional treatment modalities have achieved significant efficacy in the treatment of hepatocellular carcinoma （HCC）， there are still certain limitations. In this context， nanomedicine-based SDT leverages the targeting capabilities of nano-agents to realize specific killing of HCC cells， and furthermore， it can synergize with photodynamic therapy， chemotherapy， and immunotherapy to provide new opportunities for developing novel treatment modalities for HCC. This article reviews the mechanism of action of SDT and the advances in the research and application of SDT in the treatment of HCC， analyzes the shortcomings of existing studies， and proposes the directions for future development， in order to provide a theoretical foundation and scientific guidance for related research on HCC.

Objective To analyze the current situation of the knowledge-attitude-practice among noise-exposed workers at an airport apron. Methods A total of 494 noise-exposed workers from an airport apron were selected as the study subjects using the judgmental sampling method. A self-designed "Occupational Protection Knowledge, Attitudes, and Practices Questionnaire" was used to assess the current situation of knowledge-attitude-practice on occupational protection. Results Regarding the awareness of noise hazards among the study subjects, the awareness rates of noise-induced impairment on digestive function and reproductive system were the lowest (44.9% and 37.7%, respectively). The awareness rate of noise-induced negative emotions increased with length of service (P<0.01). Regarding the occupational protection knowledge for noise, the awareness rate of occupational noise-induced deafness was “incurable” was the lowest (39.1%). The support rate for five kinds of occupational protection attitudes for noise was generally >85.0%, while only 58.3% of the study subjects consistently or frequently wearing earplugs during work. The most common source of noise hazard and protection knowledge was pre-employment training (76.9%), followed by occupational disease prevention and control campaigns (76.1%). Conclusion Noise-exposed workers in this airport apron have incomplete awareness of non-auditory system hazards caused by noise, and the awareness of knowledge of some occupational protection is relatively low. Although their attitudes toward occupational protection are positive, many workers still fail to consistently wear personal protective equipment at work.
