BACKGROUND:The progression of chronic oral diseases is closely related to the continuous inflammatory response.Anti-inflammatory peptides are expected to become a substitute for traditional anti-inflammatory drugs due to their rich sources,easy absorption by the body and low side effects.OBJECTIVE:To review the types,anti-inflammatory mechanisms,and their application in oral related diseases.METHODS:CNKI,PubMed,and Web of Science were retrieved,with"polypeptide,anti-inflammatory,immunomodulation,oral inflammatory diseases"as Chinese and English search terms.111 articles related to the classification of anti-inflammatory peptides,anti-inflammatory mechanisms,and application of oral inflammatory diseases were selected for review.RESULTS AND CONCLUSION:(1)Anti-inflammatory peptides are abundant in nature,which can be extracted from plants,animals,and microorganisms.In addition to naturally occurring peptides and protein hydrolysates,peptides synthesized by chemical modification,computer simulation design,and genetic recombination technology can also exert anti-inflammatory effects.The composition,position,and properties of amino acids affect their anti-inflammatory activity.(2)Because the anti-inflammatory mechanism of anti-inflammatory peptides is still unclear,the activity verification is mostly cell experiments,and there is a lack of animal models,clinical trials and other further studies.(3)In the treatment of oral inflammatory diseases(including periodontitis,oral mucositis,caries,pulpitis,suppurative osteomyelitis of the jaw,and peri-implantitis),anti-inflammatory peptides can inhibit the release of inflammatory factors such as interleukin 6,interleukin 1β,and tumor necrosis factor α in oral tissues,regulate inflammatory responses,improve the chronic inflammatory environment,reduce tissue destruction and structural loss,and promote bone tissue regeneration,providing new ideas for the treatment of oral inflammatory diseases.

This paper focuses on extreme environments and systematically analyzes sleep disorders caused by multiple pathogenesis,including circadian rhythm disorder,yin-yang imbalance and qi-blood disorder under weightlessness,emotional depression due to environmental changes,abnormal diet and excretion,and six excesses pathogenic factors,in accordance with the theory of correspondence between nature and human.It proposes harmonizing yin and yang as the core therapeutic principle and guiding framework,with specific methods including calming rebellious qi-blood,regulating qi movement,harmonizing heart and kidney,and dredging and regulating blood vessels,thus forming the"one guiding principle and four specific methods"treatment strategy.Additionally,by integrating the modified application of classic formulas,a diagnostic and therapeutic approach targeting multi-dimensional pathogenesis is established.This study aims to promote the in-depth integration of Traditional Chinese Medicine(TCM)in extreme environmental medicine through TCM theories and innovative application of prescriptions,provide TCM-characterized solutions for health management of workers in extreme environments,and facilitate the transformation of extreme environmental medicine toward the modern medical model of"prevention-treatment integration".

ObjectiveTo conduct an epidemiological investigation, isolate and identify the pathogenic bacteria, and perform whole-genome sequencing (WGS) analysis of a food poisoning outbreak in Suzhou High-tech Zone, so as to provide references for the prevention and management of similar incidents. MethodsAn epidemiological investigation was carried out on affected individuals and restaurant staff. Multi-pathogen screening was performed on rectal swab samples from affected cases and restaurant staff, as well as on environmental swab samples from food preparation areas and retained food samples. WGS was performed on the pathogens isolated from the samples. ResultsA total of 15 cases were identified through hospital visit record reviews and on-site inquiries. Of the 15 case samples, 14 tested positive for Staphylococcus aureus (SA). In addition, 3 out of 15 staff samples and 6 out of 34 retained food samples tested positive for SA. WGS results revealed that the 6 food-derived isolates and 13 case-derived isolates shared the same sequence type (ST), Staphylococcal Protein A (SPA) type, and enterotoxin gene profile, with whole-genome single nucleotide polymorphism (wgSNP) differences of ≤5. Two novel SA sequence types: ST9159 and ST9161, were also identified in this study. ConclusionThis food poisoning outbreak is caused by contamination food with SA harbouring the seb and sec enterotoxin genes. The primary causes of contamination and cross-contamination included improper food handling practices, the use of the same utensils for raw and cooked foods, and extended storage of certain dishes at room temperature. Strengthening sanitary supervision in food handling facilities is crucial for reducing the occurrence of similar incidents.

Objective To explore different construction models and experiences of clinical laboratory centers under exist-ing Integrated county healthservices entity,analyze and discuss the characteristics of various construction models,and provide ref-erences for the development of county-level clinical laboratory centers.Methods Based on the five factors of"man,machine,material,method,and environment"in Total Quality Management theory,an interview outline and questionnaire were designed for county-level clinical laboratory centers.Eleven county-level clinical laboratory centers across the country were investigated to analyze their construction models,investment returns,and other aspects.Literature reviews and case studies were also conducted to summarize the construction models and characteristics of county-level clinical laboratory centers.Results The construction models of county-level clinical laboratory centers are mainly divided into five types,each with distinct features.Through an analy-sis of the investment returns of these models unde rIntegrated county healthservices entity,it was found that a profit distribution ratio of approximately 5∶5 between county-level clinical laboratory centers and township health centers for referred samples is more conducive to maintaining the stability of sample sources.The construction model of county-level clinical laboratory centers is closely related to the medical service capacity of both county and township levels.Conclusion Counties with stronger county hospital capabilities tend to establish relatively independent regional laboratory centers based on the county hospital's laboratory department.Regardless of the model,the primary goal of county-level clinical laboratory centers should be to provide high-quality testing services coverage across the entire county.The key to the success of county-level clinical laboratory centers lies in motiva-ting grassroots personnel.

Alzheimer′s disease (AD) is a neurodegenerative disorder. In the past few decades, the exact mechanisms underlying the onset of the disease have remained unclear, and treatment options are still lacking. Due to the inability of two-dimensional cell and animal models to fully simulate the pathogenesis of AD, there have been shortcomings in clinical trials of new drugs. The development of organoids and organ-on-a-chip technologies has improved the dilemma of AD research, providing reliable in vitro research models for studying pathogenic mechanisms and drug screening. This article elaborates on the applications and progress of organoids and organ-on-a-chip in AD modeling, pathogenesis, and drug development, and discusses the current limitations of organoids and organ-on-a-chip and their future perspectives.
