This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The oropouche virus (OROV) poses a threat to pregnant women and fetuses, potentially causing fetal neurological defects and even stillbirth, which has caused global attention. OROV is an arthropod-borne virus belonging to the Orthobunyavirus genus in the Bunyavirales order, primarily transmitted by arthropods and causing oropouche fever. This article reviews the etiological characteristics, epidemiological distribution, clinical symptoms, detection methods, and prevention strategies of OROV. OROV is prevalent in Central and South America, with a sharp increase in cases reported in Brazil in 2024. The virus's symptoms resemble those of several other arthropod-borne viral diseases, which can lead to misdiagnosis. Currently, there are no specific drugs or vaccines available, and treatment is mainly supportive. Culicoides paraensis and Culex quinquefasciatus are among the significant vectors of OROV. Furthermore, the article analyzes the distribution of Culex quinquefasciatus in China, highlights the risk of imported cases, proposes targeted prevention and control strategies, and underscores the significance of international cooperation in disease prevention and control.

Skeletal muscle dysfunction is a common extra-pulmonary complication in patients with chronic ob-structive pulmonary disease(COPD),significantly impacting exercise capacity and quality of life,leading to a poorer prognosis and increased mortality.Oxidative stress closely associates with the development and progression of skeletal muscle dysfunction in COPD.Exercise,a core component of pulmonary rehabilitation,stands as the primary non-pharma-cological treatment for skeletal muscle dysfunction in COPD patients and exerts a positive modulating effect on oxidative stress.This paper reviews the effects of oxidative stress on skeletal muscle dysfunction in COPD and discusses the mecha-nisms by which exercise improves skeletal muscle dysfunction in COPD from an anti-oxidative stress perspective.It has been found that oxidative stress affects the structure and function of muscles in COPD patients by upregulating the protein hydrolysis system,disrupting mitochondrial function,and impairing calcium homeostasis.Mechanisms by which exercise modulates oxidative stress to improve skeletal muscle dysfunction include the activation of antioxidant genes such as silent mating type information regulation 2 homolog 1 and nuclear factor erythroid 2 related factor to enhance the body's antioxi-dant capacity,inhibiting muscle atrophy.Exercise also regulates mitochondrial reactive oxygen species metabolism,im-proving mitochondrial function,and reduces oxidase activity to protect sarcoplasmic reticulum calcium regulation.In con-clusion,the regulation of skeletal muscle oxidative stress by exercise is a crucial target for improving skeletal muscle dys-function in COPD.

Chronic obstructive pulmonary disease(COPD)has become a common chronic disease in the adult in recent years,and more attention has been gradually paid to its prevention and treatment.This paper reviewed the clinical studies about the effect of traditional Chinese medicine(TCM)exercise therapy on COPD,and indicated that TCM exercise therapy can improve the rehabilitation of COPD patients.TCM exercise therapies,such as Tai Chi,Wuqinxi,Baduanjin,and Liuzijue,have been shown to significantly improve lung function,inflammation levels,and exercise capacity in COPD patients in recent studies.Tai Chi significantly improves patient's respiratory problems although lung function indices are not changed.Liuzijue enhances the strength and endurance of respiratory muscles and limbs.Baduanjin helps to improve patient's cognitive and emotional states.Overall,TCM exercise therapy provides an effective rehabilitation option for COPD patients.However,more clinical controlled trials are needed to further confirm their effectiveness and to develop appropriate rehabilitation programs for COPD patients.

Objective:To analyze the clinical characteristics of asymptomatic infection of brucellosis, in order to provide reference for prevention and treatment of brucellosis.Methods:Retrospective analysis was used to collect the clinical data of patients with brucellosis asymptomatic infection and confirmed cases admitted to the 940th Hospital of Joint Logistics Support Force of Chinese PLA from 2017 to 2021, and the demography characteristics, clinical manifestations and laboratory test results were analyzed.Results:The results showed that a total of 18 cases of asymptomatic infection and 85 confirmed cases of brucellosis were included, and there was no statistically significant difference in age, gender, occupation and ethnicity distribution between the two groups ( F = 7.09, χ 2 = 0.74, 4.02, 0.55, P = 0.295, 0.785, 0.327, 1.000). The 18 cases of asymptomatic infection of brucellosis were found through screening in key populations, and no clinical symptoms or abnormal imaging signs were observed. The clinical symptoms of 85 confirmed cases were mainly muscle and joint pain, fever, sweating, fatigue, and low back pain; and the imaging manifestations were mainly arthritis, splenomegaly, and spondylitis. The median percentage of eosinophils (0.70%, 1.40%), percentage of basophils (3.05%, 0.40%), C-reactive protein (1.62, 4.62 mg/L), erythrocyte sedimentation rate (1.00, 11.00 mm/h), and antibody titer of serum agglutination test (1 ∶ 100, 1 ∶ 200) showed statistically significant differences between asymptomatic infection and confirmed cases of brucellosis ( Z = - 2.97, - 5.11, - 3.49, - 3.21, - 3.50, P = 0.003, 0.001, 0.001, 0.001, 0.007). Conclusions:There is a difference in the composition of granulocytes between asymptomatic infection and confirmed cases of brucellosis, and the level of inflammatory response indicators is lower than that of confirmed cases. Regular seroepidemiological surveys among key populations can help screen for asymptomatic infection of brucellosis.

Depressive disorder ranks as a major bur-den of disease worldwide,yet the current antidepressant medications are limited by frequent non-responsiveness and significant side effects.The lateral septum(LS)is thought to control of depression,however,the cellular and circuit substrates are largely unknown.Here,we identified a subpopulation of LS GABAergic adenosine A2A receptors(A2AR)-positive neurons mediating depres-sive symptoms via direct projects to the lateral habenula(LHb)and the dorsomedial hypothalamus(DMH).Activa-tion of A2AR in the LS augmented the spiking frequency of A2AR-positive neurons leading to a decreased activation of surrounding neurons and the bi-directional manipula-tion of LS-A2AR activity demonstrated that LS-A2ARs are necessary and sufficient to trigger depressive pheno-types.Thus,the optogenetic modulation(stimulation or inhibition)of LS-A2AR-positive neuronal activity or LS-A2AR-positive neurons projection terminals to the LHb or DMH,phenocopied depressive behaviors.Moreover,A2AR are upregulated in the LS in two male mouse mod-els of repeated stress-induced depression.This identifica-tion that aberrantly increased A2AR signaling in the LS is a critical upstream regulator of repeated stress-induced depressive-like behaviors provides a neurophysiological and circuit-based justification of the antidepressant poten-tial of A2AR antagonists,prompting their clinical transla-tion.
