This study performed to determine whether OX40L overexpressed by recombinant rabies virus(LBNSE-OX40L)can enhance the innate immune response through activation of dendritic cells and thus activate early antibody production.Bone marrow dendritic cells(BMDCs)were extracted from the femur of Balb/c mice and cultured for 6 days,and the cultured BMDCs were infected with the parental virus LBNSE and the recombinant virus LBNSE-OX40L with the multiplicity of infections(MOI)=1.The effect of each virus on the maturation of BMDCs was analyzed by flow cytometry;ELISA was used to detect the expression of innate immunity-related cytokines such as interferon-α(IFN-α)and interleukin-12p40(IL-12p40)in the supernatants of the infected BMDCs.For in vivo study,Balb/c female mice were injected intramuscularly with 106 FFU of parental virus LBNSE and recombinant virus LBNSE-OX40L in both hind limbs,and the inguinal lymph nodes of mice were collected on day 6 after immunization,and the proportion of mature DCs was detected by flow cytometry.The serum was collected on day 6 after immunization,and the content of virus-neutralizing antibody(VNA)was detected by antiviral neutralizing antibody titration.Mouse serum was collected on day 6 after immunization,and virus neutralizing antibody content was measured by titration of antiviral neutralizing antibody,while IgG antibody in mouse serum was detected by ELISA.IgM antibody subclasses were detected by ELISA on days 2,4,and 6 after immunization.Compared with the parental virus LBNSE,the recombinant virus LBNSE-OX40L was able to activate more BMDCs in vitro and produce significantly higher levels of IFN-α and IL-12p40.Furthermore,the recombinant virus LBNSE-OX40L stimulated the maturation and differentiation of the DCs in vivo,which led to the rapid production of high levels of VNA and RABV-specific IgG and IgM antibodies.Taken together,LBNSE-OX40L activates dendritic cells to promote the body's innate immune response,and in turn enhances early antibody production,thus can be an early effective rabies vaccine candidate.

Background:
The incidence density of metabolic dysfunction-associated fatty liver disease (MAFLD) and the effect of a healthy lifestyle on the risk of MAFLD remain unknown. We evaluated the prevalence and incidence density of MAFLD and investigated the association between healthy lifestyle and the risk of MAFLD.
Methods:
A cross-sectional analysis was conducted on 37,422 participants to explore the prevalence of MAFLD. A cohort analysis of 18,964 individuals was conducted to identify the incidence of MAFLD, as well as the association between healthy lifestyle and MAFLD. Cox proportional hazards regression was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) with adjustments for confounding factors.
Results:
The prevalence of MAFLD, non-alcoholic fatty liver disease, and their comorbidities were 30.38%, 28.09%, and 26.13%, respectively. After approximately 70 thousand person-years of follow-up, the incidence densities of the three conditions were 61.03, 55.49, and 51.64 per 1,000 person-years, respectively. Adherence to an overall healthy lifestyle was associated with a 19% decreased risk of MAFLD (HR, 0.81; 95% CI, 0.72 to 0.92), and the effects were modified by baseline age, sex, and body mass index (BMI). Subgroup analyses revealed that younger participants, men, and those with a lower BMI experienced more significant beneficial effects from healthy lifestyle.
Conclusion
Our results highlight the beneficial effect of adherence to a healthy lifestyle on the prevention of MAFLD. Health management for improving dietary intake, physical activity, and smoking and drinking habits are critical to improving MAFLD.

PurposeVon Hippel-Lindau (VHL) syndrome is a rare autosomal dominant diseases involved multiple organs. This paper aims to explore the clinical and imaging features of VHL syndrome for the improvement of early diagnosis and treatment of this disease.Materials and Methods The clinical and imaging data, as well as their history of 5 patients with VHL syndrome were retrospectively studied. Follow-up was performed and the related literature was also reviewed.Results Among the 5 patients, 4 were found with angioreticulomas. One out of four patients simultaneously suffered from multiple angioreticulomas in brainstem, and another one had multiple cervical cord angioreticulomas. The typical MRI showed multiple cystic and solid mass with mixed intense signals, and the enhanced MRI displayed obvious enhancement in the solid part of the mass. Three patients were diagnosed with renal clear cell carcinomas. The typical CT scan showed equidensity or slightly low density signals, and the enhanced CT scan noted heterogeneous enhancement. Besides, bilateral epididymis cystadenoma occurred in one case. The ultrasonography presented heterogeneous echo and rich blood vessels. The follow-ups had been conducted till January 2015. According to the Glasgow outcome scale, three patients were in good conditions, while the other two died from renal clear cell carcinomas.Conclusion Patients with VHL syndrome usually have an unsatisfactory prognosis and most may die from renal carcinoma. Genetic test and investigation of family history should be performed as early as possible on patients with highly suspected or confirmed VHL Early treatment, life-long follow-up and periodic imaging examinations may be helpful in the prognosis.
