Here,5 important pathogens carried by ticks in Maanshan City,Anhui Province,China were identified.In to-tal,642 ticks were collected from 13 villages around Maanshan City and identified by morphological and mitochondrial COI genes.The 16S rRNA gene of Francisella tularensis,ssrA gene of Bartonella,16S rRNA,ompA and ompB genes of Rickett-sia,16S rRNA and gltA genes of Anaplasma,and groEL and rpoB genes of Coxiella were sequenced.Reference sequences were retrieved from a public database.Phylogenetic trees were constructed with MEG A1 1.0 software.In total,36 Rickettsiae isolates were detected in 640 Haemaphysalis longicornis ticks,which included 20 isolates of Rickettsia heilongjian-gensis,16 of Candidatus Rickettsia jingxinensis,2 of Ana-plasma bovis,and 186 of Coxiella-like endosymbiont.R.hei-longjiangensis HY2 detected in this study and Anhui B8 strain,Ca.R.jingxinensis QL3 and those from Shanxi Prov-ince and Jiangsu Province,A.bovis JX4 and those from Shanxi Province were clustered on the same branch.Overall,17 ticks had combined infections and none of the 5 bacteria were detected in two Amblyomma testudinarium ticks.This is the first report of Ca.R.jingxinensis detected in H.longicornis ticks from Anhui Province.It is recommended that the two types of Rickettsia that cause spotted fever and A.bovis should be reported to local health authorities to initiate appropriate prevention and control measures.

Objective:To analyze the genotype distribution and hematological characteristics of children with thalassemia in Chongqing.Methods:A total of 207 children with thalassemia admitted to Chongqing University Three Gorges Hospital from January 2021 to October 2022 were selected as the research objects.The genotype distribution and hematological characteristics were retrospectively analyzed.Results:207 cases of thalassemia were confirmed from 482 samples by gene detection,the detection rate was 42.95％,α-thalassemia accounted for 17.63％(85/482),β-thalassemia accounted for 24.27％(117/482),and compound αβ thalassemia accounted for 1.04％(5/482).A total of 5 gene mutation types of α-thalassaemia were detected in this study,which constituted 6 genotypes,αα/-SEA was the most common one,followed by αα/-α7.A total of 8 gene mutation types of β-thalassemia were detected,which constituted 9 genotypes,the top three were CD17/N,CD654/N and CD41-42/N.The highest detection rate was found in the patients aged 0-3 years(57％),and the degree of anemia was mainly mild(88.41％).97.58％of the patients were MCV＜80 fl,98.55％were MCH＜28 pg,60.87％were MCHC＜320 g/L,and 71.50％were RDW-SD＜37％.The MCV and MCH of β-thalassemia group were lower than that of α-thalassemia group,and the MCHC was higher than that of α-thalassemia group(P＜0.05),but RDW-SD was not significantly different between the two groups(P＞0.05).There were no significant differences in MCV,MCH,MCHC and RDW-SD between β+/βN and β0/βN groups(P＞0.05).The MCV and RDW-SD of--/αα thalassemia group were lower than that in-α/αα thalassemia group,the differences were statistically significant(P＜0.05),but MCH and MCHC were not significantly different between the two groups(P＞0.05).Conclusion:The genotypes of children with thalassemia in Chongqing are diverse and heterogeneous,and the majority of them are mild anemia.There are differences in haematological indexes among different genotypes of thalassemia.

Objective:To express NY-ESO-1 epitopes using circular RNA (circRNA) and construct circRNA cancer vaccines using a novel lipid-like material C1, and to evaluate the transfection efficiency and T cell activation potential at cellular level.Methods:In vitro transcription was used to synthesize mRNA and circRNA expressing EGFP and NY-ESO-1 epitopes. Then, they were transfected into COS7 cells and the expression of target proteins were detected in vitro. Lipid-like material C1 and commercial transfection agent TransIT-mRNA were used as delivery systems for mRNA NY-ESO-1 and circRNA NY-ESO-1, and their delivery efficiency was compared. Results:The expression of EGFP was observed under fluorescence microscopy after transfection of mRNA EGFP and circRNA EGFP into COS7 cells for 24 h. The secretion of IFN-γ by T cell receptor-engineered T (TCR-T) cells targeting NY-ESO-1/HLA-A2 was stimulated by COS7-A*02: 01 cells transfected with mRNA NY-ESO-1 and circRNA NY-ESO-1. Compared with mRNA NY-ESO-1, circRNA NY-ESO-1 was able to express the target antigen and stimulate the target cells to release IFN-γ more persistently. The delivery efficiency of C1 material was better than that of commercial transfection reagents when COS7 cells were transfected in vitro. Conclusions:Compared with the linear mRNA, transfection of COS7-A*02: 01 cells with circRNA can lead to more efficient and durable activation of T cells, suggesting that it could be a more suitable candidate for clinical treatment of tumors in the future. The lipid-like material C1 can effectively deliver linear mRNA and circular RNA molecules. This study provides reference for further research on circRNA tumor vaccines.

Objective:This study aims to compare the antiviral treatment similarities and differences in the population covered by the 2024 version of the World Health Organization's (WHO) hepatitis B prevention and treatment guidelines and the current Chinese hepatitis B prevention and treatment guidelines, so as to explore their impact on the indications for antiviral therapy in Chinese patients with chronic hepatitis B (CHB).Methods:The information of patients with chronic hepatitis B virus infection who did not receive antiviral treatment was collected through the registration database of the China Clinical Research Platform for Hepatitis B Elimination. Descriptive statistics were conducted on the demographic, blood, biochemical, and virological levels of patients according to the treatment recommendations of the two versions of the guidelines. The Mann-Whitney U test and χ2 test were used to compare the differences and proportional distribution of the treatment populations covered by the two guidelines. The χ2 test was used to analyze the coverage rate of different antiviral treatment indications.Results:A total of 21,134 CHB patients without antiviral treatment were enrolled. 69.4% of patients met the 2024 versions of the WHO guidelines' recommendations. 85.0% of patients met the current Chinese hepatitis B prevention and treatment guidelines. The WHO guidelines for antiviral therapy indications were met in younger patients with higher levels of ALT, AST, and APRI scores, as well as greater proportion of patients with higher viral loads (P<0.001). The WHO guidelines recommended a cut-off value of APRI>0.5, which raised the proportion of patients on antiviral therapy from 6.6% to 30.9%. 45.7% of patients met the antiviral indications for HBV DNA >2000 IU/ml with abnormal transaminase (ALT>30 U/L for males and ALT>19 U/L for females). The reduced APRI diagnostic cut-off value and ALT treatment threshold had further increased the treatment coverage rate by 91.6% in patients with chronic HBV infection in line with the 2024 versions of WHO guidelines.Conclusion:The reduction of the APRI diagnostic cut-off value and the ALT treatment threshold, based on the current hepatitis B guidelines of China, will further improve the treatment coverage of CHB patients.

Objective To investigate the efficacy and safety of nusinersen sodium in the treatment of children with spinal muscular atrophy(SMA).Methods A retrospective analysis was conducted on the clinical data of 50 children with 5q SMA who received nusinersen sodium treatment and multidisciplinary treatment management in Shanxi Children's Hospital from February 2022 to February 2024.Results Compared with the baseline data,67%(8/12),74%(35/47),and 74%(35/47)of the SMA children had a clinically significant improvement in the scores of Philadelphia Infant Test of Neuromuscular Disorders,Hammersmith Functional Motor Scale Expanded,and Revised Upper Limb Module,respectively,and the distance of 6-minute walking test increased from 207.00(179.00,281.50)meters to 233.00(205.25,287.50)meters(P<0.05)after nusinersen sodium treatment.Of all 50 children with SMA,24(48%)showed good tolerability after administration,with no significant or persistent abnormalities observed in 2 034 laboratory test results,and furthermore,there were no serious or immunological adverse events related to the treatment.After treatment,there was a significant change in forced vital capacity as a percentage of the predicted value in 27 children with restrictive ventilatory dysfunction,as well as a significant change in the level of 25-(OH)vitamin D in 15 children with vitamin D deficiency(P<0.05).Conclusions For children with SMA,treatment with nusinersen sodium can continuously improve the response rates of motor function scales,with good tolerability and safety.
