Aeromedical evacuation, a crucial method for casualty transport, significantly enhances survival rates by providing exceptionally rapid transfer and thus gaining valuable treatment time. However, due to the contamination risks during the transport of radioactively contaminated casualties, aeromedical evacuation has not been widely adopted for this specific scenario. This paper reviews the current status of aeromedical evacuation for radioactively contaminated casualties and identifies several challenges. These include incomplete evacuation procedures and regulatory frameworks, difficulties in rapid triage and classification, inadequate evacuation and loading equipment, and the complexity of managing specific injuries during flight. We propose corresponding strategies to address these issues, aiming to provide a reference and guidance for the advancement of aeromedical evacuation for radioactively contaminated casualties.

Periodontitis is closely related to systemic health,especially adverse pregnancy.Periodontal pathogens are actively in-volved in the formation and development of intrauterine infections.Studies have shown that infection by periodontal pathogens is an im-portant risk factor for adverse pregnancy.Periodontal pathogens reach the uterus via the hematogenous or retrograde route,and the bacte-ria,their virulence factors,and the immunoinflammatory mediators produced by the pathogens promote each other and together mediate the development of intrauterine infections and ultimately lead to adverse pregnancies.This article reviews the role of periodontitis and perio-dontal pathogens in adverse pregnancies and their mechanisms of infection to provide new possibilities for improving the birth rate.

Objective Ulcerative colitis(UC)is a chronic inflammatory bowel disease with a prolonged course and no cure.The purpose of this study was to systematically evaluate the clinical effect and safety of Bai-tou-weng-tang(BTW)combined with amino salicylic acid(ASA)in the treatment of UC.Methods The relevant Chinese and English databases were searched,and the eligible literatures were screened using inclusion and exclusion criteria and evaluated for quality.Relative risk(RRs),weight mean differences(WMDs)and 95％confidence intervals(CIs)were used to evaluate the clinical effect,safety and other indicators of different drugs for UC.Sensitivity analysis and publication bias were used to evaluate the stability of the results.Results A total of 61 clinical studies were included,involving 5483 patients with UC.The results of meta-analysis showed that BTW combined with ASA not only had better cure rate(RR=1.85,95％CI:1.62-2.10)and total efficiency rate(RR=1.23,95％CI:1.19-1.26),but also could reduce the incidence of adverse reactions(RR=0.61,95％CI:0.42 to 0.89)and recurrence rate(RR=0.33,95％CI:0.20 to 0.57).In addition,BTW combined with ASA had better efficacy in improving patients'syndrome,disease severity,intestinal mucosal score under colonoscopy,histopathological score and quality of life.Finally,BTW combined with ASA can regulate the levels of serum inflammatory factors and immunological indexes after treatment.Conclusion BTW combined with ASA can not only improve the clinical effect of UC patients,but also improve safety,which may be a new way to treat UC.

Palatal radicular groove is a developmental malformation of maxillary incisors, lateral incisors in particular, which often causes periodontal destruction. This paper reports a case of combined periodontal-endodontic lesions induced by palatal radicular groove, which was initially misdiagnosed as a simple periapical cyst. After root canal therapy and periapical cyst curettage, the course of disease was prolonged, resulting in the absence of buccal and maxillary bone plates in the affected tooth area. After the etiology was determined, the affected tooth was extracted and guide bone tissue regeneration was performed at the same time, followed by implantation and restoration at the later stage, leading to clinical cure. The palatal radicular groove is highly occult, and the clinical symptoms are not typical. If the abscess of the maxillary lateral incisor occurs repeatedly, and the abscess of the maxillary lateral incisor has not been cured after periodontal and root canal treatment, cone-beam computed tomographic and periodontal flap surgery should be considered.

OBJECTIVES: There is currently a lack of economic and suitable animal models that can accurately recapitulate the oral submucous fibrosis (OSF) disease state for indepth study. This is one of the primary reasons for the limited therapeutic methods available for OSF. Based on the underlying logic of pan-cancer analysis, this study systematically compares OSF and the other four types of organ fibrosis from the aspects of molecules, signaling pathways, biological processes, etc. A comprehensive analysis of the similarities and differences between OSF and other organ fibrosis is helpful for researchers to discover some general rules of fibrosis disease and may provide new ideas for studying OSF. METHODS: Microarray data of the GSE64216, GSE76882, GSE171294, GSE92592, and GSE90051 datasets were downloaded from GEO. Differentially expressed mRNAs (DEmRNAs) of each type of fibrosis were identified by Limma package. Weighted gene co-expression network analysis (WGCNA) was used to identify each type of fibrosis-related module. The similarities and differences of each fibrosis-related-module genes were analyzed by function and pathway enrichment analysis. RESULTS: A total of 6 057, 10 910, 27 990, 10 480, and 4 801 DEmRNAs were identified in OSF, kidney intestinal fibrosis (KIF), liver fibrosis (LF), idiopathic pulmonary fibrosis (IPF), and skin fibrosis (SF), respectively. By using WGCNA, each type of fibrosis-related module was identified. The co-expression networks for each type of fibrosis were constructed respectively. Except that KIF and LF have 5 common hub genes, other fibrotic diseases have no common hub genes with each other. The common pathways of OSF, KIF, LF, IPF, and SF mainly focus on immune-related pathways. CONCLUSIONS OSF and the other 4 types of fibrotic diseases are tissue- and organ-specific at the molecular level, but they share many common signaling pathways and biological processes, mainly in inflammation and immunity.
