Objective To understand the epidemiological characteristics of scrub typhus disease and to provide a scientific basis for the prevention and control of scrub typhus disease. Methods Descriptive epidemiological methods were used to analyze the population and regional distribution of scrub typhus. Seasonal characteristics were analyzed using concentration method and circular distribution method, and incidence trend was analyzed using joinpoint regression model. Results The annual incidence rate of scrub typhus was 0.95/100 000 from 2010 to 2022. The incidence rate of male was 0.77/100 000, lower than that of female 1.12/100 000 (χ2=18.89, P<0.05). The incidence rate of the 60-74 years old group was 3.38/100,000, and the total number of cases in the age group 45-74 years was 416 (74.95%). Occupational distribution was mainly among farmers, with 448 cases (80.72%). The top three regions with the highest number of reported cases (in order: Donghai County, Ganyu District, and Guannan County) reported a total of 416 cases, accounting for 74.95%. Concentration ratio was M=0.9408, and the incidence of scrub typhus disease was strictly seasonal. Circular distribution results showed a-=-62.3728, S=20.8960. The circular distribution results indicated that the peak day was October 19th, and the peak period was between October 7 to December 19. The average annual percentage change (AAPC) of the incidence rate from 2010 to 2022 was 13.70%, 95% CI (-8.62%~41.48%), and the incidence rate showed an upward trend (t=1.15, P=0.249). Conclusion The incidence of scrub typhus disease is strictly seasonal, and the incidence rate over the years shows an upward trend. It is necessary to strengthen monitoring and take various intervention measures to reduce the risk of scrub typhus disease.

Objective Recombinase-aided polymerase chain reaction(RAP)is a sensitive,single-tube,two-stage nucleic acid amplification method.This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA),and Acinetobacter baumannii(AB)in the bloodstream based on recombinant human mannan-binding lectin protein(M1 protein)-conjugated magnetic bead(M1 bead)enrichment of pathogens combined with RAP. Methods Recombinant plasmids were used to evaluate the assay sensitivity.Common blood influenza bacteria were used for the specific detection.Simulated and clinical plasma samples were enriched with M1 beads and then subjected to multiple recombinase-aided PCR(M-RAP)and quantitative PCR(qPCR)assays.Kappa analysis was used to evaluate the consistency between the two assays. Results The M-RAP method had sensitivity rates of 1,10,and 1 copies/μL for the detection of SA,PA,and AB plasmids,respectively,without cross-reaction to other bacterial species.The M-RAP assay obtained results for<10 CFU/mL pathogens in the blood within 4 h,with higher sensitivity than qPCR.M-RAP and qPCR for SA,PA,and AB yielded Kappa values of 0.839,0.815,and 0.856,respectively(P<0.05). Conclusion An M-RAP assay for SA,PA,and AB in blood samples utilizing M1 bead enrichment has been developed and can be potentially used for the early detection of bacteremia.

Objective To explore the lateral lymph node metastasis in patients with rectal cancer below peritoneal reflection and construct predictive models.Methods A total of 102 patients with rectal cancer be-low peritoneal reflection admitted in the hospital from January 2020 to April 2023 were selected as the re-search objects.According to the existence of lateral lymph node metastasis(LLNM),the patients were divided into metastatic group(n=31)and non-metastatic group(n=71).The general clinical data,tumor pathologi-cal features,laboratory indexes[carcinoembryonic antigen(CEA).carbohydrate antigen 199(CA199),neutro-phil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),transforming growth factor(TGF)-α and TGF-β1]between the two groups were compared.The risk factors of LLNM in patients with rectal cancer be-low peritoneal reflection were screened by Spearman correlation analysis and Logistic regression analysis,and the predictive model was constructed and the efficacy of the model was evaluated.Results The mean maxi-mum tumor diameter,the short diameter of lateral lymph nodes,the proportion of poorly differentiated pa-tients and the proportion of patients with T3-T4 stage in the metastasis group were significantly higher than those in the non-metastasis group(P<0.05).The average levels of TGF-α,TGF-β1 and NLR in the metasta-sis group were significantly higher than those in the non-metastasis group(P<0.05).Spearman correlation a-nalysis,univariate and multivariate Logistic regression analysis showed that poor differentiation,T3-T4 stage,maximum tumor diameter,longer short diameter of lateral lymph nodes,higher levels of TGF-α,TGF-β1 and NLR were independent risk factors for LLNM in patients with rectal cancer below peritoneal reflec-tion.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of the predictive model based on the above risk factors was 0.915(95%CI:0.847-0.984),which had high pre-dictive performance.Conclusion Patients with LLNM and rectal cancer below peritoneal reflection often have longer tumor diameter and lateral lymph node short diameter,and higher levels of TGF-α,TGF-β1 and NLR.Lateral lymph node dissection should be actively carried out for patients with above characteristics,and timely monitoring should be carried out to see if there is still lymph node metastasis after surgery,so as to provide certain clinical basis for improving the judgment of LLNM in rectal cancer below peritoneal reflection.
