This study aims to inquire about the fluctuations of ubiquitin-specific protease 47 on neu-roblastoma cells(Neuro-2a,N2a)infected by rabies virus(RABV).USP47 expression levels were detected after RABV infection in N2a cells through RT-qPCR,protein immunoblotting,and virus titer determination.The levels of RABV nucleoprotein and phosphoprotein gene and protein,and RABV titers in supernatants were analyzed during overexpression and knockdown of USP47.The results showed that RABV infection increased USP47 gene level in N2a cells.When overexpression of USP47,the levels of RABV N and P were increased,and the virus titers were also improved.Mo-reover,the level of interleukin-6(IL-6)genes decreased.Knocking down USP47 expression reduced levels of RABV N and P genes and proteins,lowered the virus titer,and elevated the IL-6 gene lev-el.The results suggest that USP47 promotes RABV infection and suppresses IL-6 expression.This finding lays the foundation for further investigation into the molecular mechanisms by which USP47 regulates RABV infection.

This study identified the types and pathogen carrying status of fleas on the surface of sheep in some areas of southern Xinjiang,and analyzed the genetic evolution differences with respect to related pathogens.The aim was to provide a reference for the local prevention and control of fleas and insect borne infectious diseases.A total of 1 586 fleas were collected from agricultural and pas-toral areas of Tumushuke City and Hotan Prefecture.Flea species were identified on the basis of morphology and the Pulex irritans mi-tochondrial COII gene.Flea DNA was extracted,and PCR was conducted to amplify the Bartonella gltA gene;Arsenophonus,Ana-plasma,Ehrlichia,and Wolbachia 16S rRNA genes;RickettsiaOmpA,17kDa,16S rRNA genes,and Yersinia pestis 16S rDNA gene.The amplified products were sequenced,and the homology of the genes of the three detected pathogens(gltA gene of Bartonella,16S rRNA gene of Wolbachia,and Anaplasma phagocytophilum)with respect to known corresponding genes of the same pathogen in Gen-Bank was analyzed.Phylogenetic trees were constructed with the adjacency method in MEGA 11.0.According to morphological and mo-lecular biology identification results,all fleas collected in this study were Pulex irritans.PCR indicated that the target gene fragments had been added to the mitochondrial COII,BartonellagltA,Wolbachia,and autophagosomal 16S rRNA genes of human fleas,all of which were consistent with the expected fragment sizes.Target bands were not amplified from Ehrlichia,Arsenophonus,spotted fever group Rickettsia,and Yersinia pestis.According to homology and genetic evolution analysis of human flea mitochondrial COII and the corresponding genes of the above-described pathogens,the COX2 gene(ON455234.1)of human fleas in Tumushuke city and Iran ob-tained in this study showed the highest homology(99.84%).The COII gene(NC_063709.1)of human fleas in Hetan City and Hunan region showed the highest homology(100%).Our findings further confirmed that the flea species was Pulex irritans.The PCR amplifi-cation results indicated that the collected Pulex irritans carried multiple pathogens,among which Bartonella and Wolbachia had the highest infection rates,and the infection rate with Anaplasma phagocytophilum was relatively low.This study is the first to discover flea species on the surface of sheep in some areas of southern Xinjiang.Our findings preliminarily confirmed that Bartonella,Wolba-chia,and Anaplasma phagocytophilum are the main Pulex irritans pathogens.

Radionuclide drug conjugates(RDC)represent the culmination of interdisciplinary integra-tion.By virtue of their precise targeting capability,high diagnostic sensitivity,and remarkable therapeutic effi-cacy in tumor diagnosis and treatment,RDC has emerged as promising theranostic agents with immense applica-tion potential.This article systematically reviews the progress in RDC development in China from 2009 to 2024,encompassing an overview of RDC,its structure and classification,trends in clinical research,advances in clinical trials,and national policy support.The aim is to provide valuable insights for researchers in related fields,thereby facilitating further development and application of RDC-based therapeutics.

Objective:To explore the distribution characteristics of HBsAg levels in treatment-na?ve and treatment-experienced patients with chronic hepatitis B (CHB) in China.Methods:Data were obtained from the China Registry of Hepatitis B (CR-HepB) platform from the establishment of the platform to April 11, 2024. Patients with CHB who were treatment-na?ve and treatment-experienced with nucleos(t)ide analogs (NAs) were included. Relevant clinical data were collected. The distribution of hepatitis B surface antigen (HBsAg) status, as well as the levels in populations of different age groups after different antiviral treatment durations, were retrospectively analyzed. Normally and non-normally distributed measured data were represented by Mean± SD, and M( Q1, Q3). Results:A total of 13 505 treatment-na?ve patients and 6 390 treatment-experienced patients were included in the analysis. The proportions of treatment-na?ve patients with HBsAg<100, <500, and <1 500 IU/mL were 10.51%, 28.47%, and 46.85%, and the corresponding proportions of treatment-experienced patients were 12.88%, 29.84%, and 52.07%. The proportions of treatment-na?ve patients with HBsAg levels≥1 500, ≥3 000, and≥8 000 IU/mL were 53.15%, 38.17%, and 15.62%, and the corresponding proportions of treatment-experienced patients were 47.93%, 31.77%, and 10.39%. HBsAg level showed a trend of gradual decrease with the increase of antiviral treatment time. The proportion of treatment-experienced patients with HBsAg<100 IU/mL increased from 12.73% when the treatment duration was less than three years to 26.92% when the treatment duration was≥10 years, while the proportion of patients with HBsAg levels≥3 000 IU/mL or≥8 000 IU/mL decreased from 34.66% to 23.08% and from 12.19% to 5.77%, respectively. The proportion of patients with HBsAg<100, <500, and<1 500 IU/mL increased with age, while the proportion of patients with HBsAg≥1 500, ≥3 000, and ≥8 000 IU/mL decreased sequentially.Conclusions:The CR-HepB platform provides a basis for clarifying the serum HBsAg levels in treatment-na?ve and treatment-experienced CHB patients in China. The HBsAg status indicates that with a prolonged antiviral treatment duration, there is a gradual decline trend in HBsAg level.

Objective To analyze the influence of medication compliance of chronic type 2 diabetes management patients on disease control in two communities in Kunming.Methods A total of 138 patients with type 2 diabetes who were included in chronic disease management in Guandu and Xiaobanqiao communities of Kunming were selected from December 2021 to September 2022.Basic information collection and HbAlc and other related tests were improved.A questionnaire survey of 8-item Morisliy medication adherence scale(MMAS-8)was conducted to analyze the levels of HbAlc and other indexes of three groups with high(group A),medium(group B),and low(group C)adherence,and to conduct statistical analysis.Results Group A accounted for 22.5%,group B for 44.9%,and group C for 32.6%.There were significance differences in urinary albumin creatinine ratio(UACR),HbA1c and blood creatinine among the three groups(P<0.05).The levels of UACR,HbAlc and serum creatinine in group A were lower than those in group B and group C,and there was a negative correlation between UACR,HbAlc and serum creatinine and medication compliance rate(P<0.05).Conclusion In the Guandu Community and Xiaobanqiao community of Kunming,only 22.5%of patients with chronic type 2 diabetes had high medication compliance.The higher the compliance,the lower the level of UACR,HbAlc and serum creatinine,there is a correlation between the two,suggesting that medication compliance should be regarded as one of the key points in the management of chronic diabetes mellitus in the community,and the intervention of patients'medication compliance should be strengthened.
