Objective To express the recombinant caspid of genotype 4 hepatitis E virus(HEV) ORF2. Methods HEV recombinant capsid protein D66 was expressed in E. coli, using the ORF2 fragment (aa368-606, obtained from swine bile) of genotype 4 HEV. Results The recombinant capsid proteins D66 self-assemble to be particle with a radius of 13 nm through dimeric form in neutral solution. Coated particles reacted well with sera obtained from patients during acute or recovered phase of HEV infection. Immunofluorescence and immnoblot assay suggested that D66 bound and penetrated HepG2 cell lines, and the process of attachment was blocked by sera collected from patients during acute or recovered phase of HEV infection.Conclusion Recombinant D66 particles simulate the structure at the surface of genotype 4 HEV well and specifically adhere and penetrate the host cells, which lays the foundation for the investigation of the molecular mechanism of genotype 4 HEV infection.

Objective To study the clinical efficacy of the combination of sephedex and docetaxel used in transcatheter arterial chemoembolization (TACE) for clinical treatment of primary liver cancer.Methods 120 patients with primary liver cancer in our hospital were divided into the experimental group and the control group randomly and equally, the 60 cases in experimental group were treated with sephedex suspensoid (Sephedex, G-50, 300-500 μm) and docetaxel-iodized oil, while other 60 cases in control group were treated with docetaxel-iodized oil suspension liquid.Results The success rate of surgical intubation in the two groups was 100%.After an average follow-up of 12 months, the postoperative tumor diameter of the experimental group was reduced by (4.4±1.4) cm, while that of the control group was (1.8±1.0) cm;The overall response rate was 70% in the experimental group in contrast to 30% in the control group;the alpha fetal protein (AFP) value was decreased by (33.2±15.2) μg/L in the experimental group and (10.4±9.8) μg/L in the control group.Conclusion The combination of sephedex, docetaxel suspensoid and iodized oil shows great potential in TACE treatment of primary liver cancer, from which the treatment effect can be improved significantly.

Objective To investigate the prognostic value of N6-methyladenosine (m⁶A) modification related genes and immune infiltration in colorectal cancer (CRC) and construct a risk model for predicting outcome of patients. Methods The transcriptome data and matched clinical information of CRC patients were downloaded from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. The prognostic value of m⁶A modification related genes and immune infiltration were investigated using the consensus clustering method and single sample gene set enrichment analysis. The weighted gene co-expression network analysis (WGCNA) was used to identify prognostic genes related with m⁶A modification and immune infiltration. Lasso regression analysis was used to construct a multi-gene risk model. The expression differences of prognostic genes identified were further validated through expression differential analysis in the Gene Expression Profiling Interactive Analysis (GEPIA) database. Finally, the Kaplan-Meier was used to evaluate the predicting performance of the model in different subgroups and external validation cohorts. Results Both the m⁶A modification and immune infiltration phenotype could effectively stratify the prognosis of CRC patients from the TCGA cohort. Most m⁶A modification related genes were significantly correlated with immune infiltration in CRC tissues. Four following prognostic genes were selected using the WGCNA method combined with Lasso regression analysis: intelectin-1, lymphocyte antigen 6 complex locus G6D, atonal homolog 1 and matrix metalloproteinase 28. In colorectal cancer tissues, the expression levels of lymphocyte antigen 6 complex locus G6D and matrix metalloproteinase 28 exhibited significant differences compared to adjacent non-cancerous tissues (P < 0.05). The risk model constructed based on the above prognostic genes can effectively identify the potential risk population with poor prognosis in different clinical subgroups of the TCGA cohort and the GEO validated cohort. Conclusion A risk model based on m⁶A modification and immune infiltration could effectively predict the clinical outcome of CRC patients, and related prognostic genes have potential to be developed as molecular targets for CRC therapy.
