Objective To analyze the application characteristics,trends,and special advantages of anti-infection research using the Bayesian method,and to provide methodological reference for the development of anti-infection research.Methods PubMed,CNKI and WanFang Data were electronically searched for the studies on anti-infection using Bayesian method published from January 1,2015 to November 21,2023.The relevant information of publication time,anti-infection type,sample size,Bayesian characteristics and Bayesian application pattern were analyzed descriptively and reviewed.Results A total of 86 studies were included,of which 41.9％were observational studies,only 7.0％were enterprise-initiated studies,and 48.8％were mentioning prior information studies.There was no domestic intervention study.The application characteristics and advantages of Bayesian method in intervention study,observational study and pharmacokinetic study are different.In intervention researches and observational researches,the application of Bayesian design decision and the application of Bayesian analysis and estimation accounts for 69.2％and 52.8％at most,respectively.Conclusions The Bayesian method is flexible,can be used for small sample sizes and complex model research,and can deal with uncertainty.In intervention studies in the field of anti-infection in China,the Bayesian method has not been applied widely.Only a handful of studies applying Bayesian method have been initiated by companies.In the future,it is still necessary to promote the advantages and application scenarios of Bayesian methods in the field of anti-infection research and strengthen the standardization of the application of Bayesian method.

To investigate the distribution and development of common allergens in children in Hangzhou area, and to provide an epidemiological basis for the prevention, diagnosis, and treatment of allergic diseases in this area. This study is a retrospective study, selecting 3 524 children who underwent allergen screening at DiAn Medical Laboratory Center (Hangzhou) Co., Ltd. from January 2022 to January 2024 as the research subjects, including 2 012 males and 1 512 females. Among them, there were 1 098 infants (0-1 year olds), 1 673 toddlers (1-3 year olds), and 753 children (3-14 year olds). Immunoblotting was used to detect 21 allergen-specific immunoglobulin E (sIgE) antibodies. The positive rates of various allergens were calculated according to gender, age, and other factors, and the epidemiological characteristics and trends were analyzed. The results showed that the overall positive rate of sIgE was 60.33% (2 126/3 524). The main inhaled allergens were Dermatophagoides pteronyssinus/Dermatophagoides farinae (992, 28.15%), dog dander (295, 8.37%) and cat dander (181, 5.13%). The main food allergens were milk (696, 19.75%), egg white (541, 15.36%) and shrimp (205, 5.83%). Boys had significantly higher sIgE positivity rates than girls for Dermatophagoides pteronyssinus/Dermatophagoides farinae(642, 31.90%, χ2=10.10, P=0.001), house dust(61, 3.02%, χ2=5.12, P=0.024), cat dander(124, 6.16%, χ2=4.06, P=0.044), mold combinations(103, 5.14%, χ2=7.51, P=0.006), and tree pollen combinations(42, 2.07%, χ2=5.44, P=0.020) (all P<0.05); With age, there was a significant increase in positivity rates for house dust mite/dust mite, house dust, mold combinations, milk, and beef (all P<0.05), and a significant decrease in positivity rates for cockroach consumption, egg whites, shrimp, crab, cod, lobster/scallop, and soybeans (all P<0.05), the positive rates of only ingestive allergens decreased significantly ( P<0.001), and the positive rates of only inhalant and mixed allergens increased significantly ( P<0.001). In conclusion,in the Hangzhou area, dust mites are the most common inhalant allergens among children with allergic diseases, while milk is the most common food allergen. Boys are more sensitive to inhalant allergens, and as children grow older, the positive rates for different allergens undergo significant changes. Dynamic monitoring of changes in specific IgE antibodies to various allergens can assist in the diagnosis, prevention, and treatment of allergic diseases.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To assess the effect of early nutritional intervention on the patients with respiratory diseases at nutritional risk. Methods A total of 130 patients with respiratory disease who were hospitalized in Shanghai Fifth People’s Hospital, Fudan University between May 2023 and December 2024 and had a nutritional risk screening 2002 score ≥3 points. Based on the initiation time of nutritional intervention, patients were divided into an early group (≤5 days, n＝65) and a late group (＞5 days, n＝65). Results In the early group, prealbumin (P-ALB) and retinol-binding protein (RBP) levels were significantly higher (P＜0.01), C-reactive protein (CRP), procalcitonin (PCT) levels were significantly lower after intervention (P＜0.05). Compared with the late group, the hospital costs were lower and hospital stays were shorter in the early group (P＜0.001). Spearman analysis showed ALB, P-ALB, and total protein (TP) were negatively correlated with hospital costs (r＝－0.37, －0.20, and－0.22, P＜0.05). RBP, ALB, P-ALB, and lymphocyte count (LYM) were negatively correlated with CRP (r＝－0.30, －0.26, －0.37, －0.18, P＜0.01), RBP, ALB, P-ALB, hemoglobin (HB), and TP were negatively correlated with PCT (r＝－0.23,－0.36, －0.40, －0.30, －0.19, P＜0.05). Conclusions For patients with respiratory diseases, early nutritional assessment should be underwent, and for patients with nutritional risk screening 2002 score ≥3 points, early nutritional intervention could improve the nutritional status and alleviate inflammatory response, promote recovery, shorten the hospital stays.
