By systematically reviewing the concept evolution of pre-chronic obstructive pulmonary disease （pre-COPD） and the research status of traditional Chinese medicine （TCM）， as well as considering the clinical practice， this paper puts forward the strategies for the prevention and treatment of pre-COPD with TCM. These strategies include identifying high-risk groups by combining TCM syndrome and constitution， advocating the principle of "treating disease before it arises" and promoting the combination of syndrome differentiation and constitution evaluation to achieve individualized intervention， promoting collaboration between TCM and western medicine， supported by digital and intelligent technologies， to establish a whole-process management mode of "hospital-community-family". The aim is to realize the early diagnosis， early intervention and whole-process management of pre-COPD， thereby helping reduce the incidence of COPD.

Objective: To examine the association between academic stress and anxiety-depression comorbidity among college students and the potential moderating effect of physical activity, so as to provide a theoretical basis for the development of evidence based mental health promotion frameworks in higher education institutions. Methods: From October 2022 to June 2024, a total of 7 980 students from 21 universities across five provinces/municipalities in China, including Shanghai, Jiangsu, Zhejiang, Shandong, and Anhui, using a combination of convenience sampling and stratified random cluster sampling. Physical activity, academic stress, anxiety, and depression were assessed by using the 24 hour Movement Behaviors Questionnaire, the Chinese College Students Mental Health Screening Scale, the Generalized Anxiety Disorder-7, and the Center for Epidemiologic Studies Depression Scale, respectively. Binary Logistic regression was used to examine the associations between academic stress and anxiety, depression, and their comorbidity. The PROCESS macro was employed to test the moderating effect of physical activity. Results: The prevalence of anxiety-depression comorbidity among college students was relatively high (11.53%), with significant differences observed across grades and body mass index (BMI) categories ( χ 2=70.30, 24.63, both P <0.01). Binary Logistic regression revealed that, compared with low academic stress, moderate academic stress among male students was significantly associated with greater odds of anxiety ( OR =2.78), depression ( OR =2.75), and anxiety-depression comorbidity ( OR =2.89) (all P <0.01). High academic stress was associated with elevated odds of anxiety ( OR =6.66), depression ( OR =12.81), and anxiety-depression comorbidity ( OR =13.65) (all P <0.01). Among female students, moderate academic stress was associated with anxiety ( OR =2.58), depression ( OR =1.52), and anxiety-depression comorbidity ( OR =1.70) (all P <0.01). High academic stress increased the risk of anxiety ( OR =6.77), depression ( OR =6.81), and anxiety-depression comorbidity ( OR =7.48) (all P <0.05). The moderation analysis indicated that the interaction between total physical activity duration and academic stress had a significant netative moderating effect on anxiety-depression comorbidity among college students ( β =-0.03, P <0.01). Conclusions Academic stress increases the risk of anxiety, depression, and anxiety-depression comorbidity among college students. Physical activity may attenuate the adverse effects of academic stress on anxiety-depression comorbidity.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

The development, progression, and curative efficacy of head and neck squamous cell carcinoma (HNSCC) are influenced by complex interactions between epithelial and immune cells. Nevertheless, the specific changes in the nature of these interactions and their underlying molecular mechanisms in HNSCC are not yet fully understood. Cuproptosis, a form of programmed cell death that is dependent on copper, has been implicated in cancer pathogenesis. However, the understanding of cuproptosis in the context of HNSCC remains limited. In this study, we have discovered that cuproptosis-related long non-coding RNAs (CRLs) known as JPX play a role in promoting the expression of the oncogene urokinase-type plasminogen activator (PLAU) by competitively binding to miR-193b-3p in HNSCC. The increased activity of the JPX/miR-193b-3p/PLAU axis in malignant epithelial cells leads to enhanced cell proliferation, migration, and invasion in HNSCC. Moreover, the overexpression of PLAU in tumor epithelial cells facilitates its interaction with the receptor PLAUR, predominantly expressed on macrophages, thereby influencing the abnormal epithelial-immune interactome in HNSCC. Notably, the JPX inhibitor Axitinib and the PLAU inhibitor Palbociclib may not only exert their effects on the JPX/miR-193b-3p/PLAU axis that impacts the malignant tumor behaviors and the epithelial-immune cell interactions but also exhibit synergistic effects in terms of suppressing tumor cell growth and arresting cell cycle by targeting epidermal growth factor receptor (EGFR) and cyclin-dependent kinase (CDK4/6) for the treatment of HNSCC.

Therapeutic plasma exchange can quickly remove the pathogenic macromolecular sub-stance in vivo,and its application is gradually expanded. With the maturity and development of plasma ex-change technology,the effect of high volume plasma exchange in liver failure,thrombotic thrombocytopenic purpura,sepsis and other diseases is obvious. But there is still controversy about the wide use of high volume plasma exchange in ICU. This review aimed to discuss the use of high volume plasma exchange in patients with critical diseases.
