Objectives To express the miracidial antigen from eggs of Schistosoma japonicum (Chinese mainland strain) (SjMP10), and investigate the role of the miracidial antigen during the hepatic granuloma formation of schistosomiasis. Methods A pair of specific primers was designed and synthesized according to the nucleotide sequence of the open reading frame of the miracidial antigen gene. The open reading frame of the miracidial antigen gene was amplified, digested by restrictive enzyme(BamHI, SalI), and cloned directly into the expression plasmid pGEX-4T-3 to construct the recombinant plasmid. The recombinant plasmids were transformed into E. coli BL21(DE3), and induced by IPTG to express the fusion protein of GST-SjMP10. The expressed fusion protein was purified by electric elution method, and its antigenicity was examined by Western blotting and lymphocyte proliferation test. Results The gene of miracidial antigen was cloned into the expression plasmid pGEX-4T-3. After induced by IPTG, the recombinant expressed a fusion protein of GST-SjMP10, with a molecular weight of 39 000 approximately. The purified fusion protein showed proper antigenicity that could be recognized by the sera of rabbits heavily infected by Schistosoma japonicum and could stimulate the proliferation of splenic lymphocytes of infected BALB/c mice. Conclusion The miracidial antigen from eggs of Schistosoma japonicum was expressed successfully.

Objective:To identify the hub differentially expressed genes(DEGs)of glomerular pathological changes and potential pathways in molecular process of type 2 diabetic nephropathy(DN)based on bioinformatics technology.Methods:The differentially expressed genes of Gene Expression Omnibus(GEO)dataset GSE96804 in DN and normal kidney tissues were analyzed by R 3.6.2 software. DEGs were further assessed by Gene Ontology(GO)function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signal pathway analysis. Subsequently, the hub genes and their associated pathways were analyzed using String 11.0 and Cytoscape 3.7.2 software.Results:A total of 168 DEGs were obtained in the dataset. Among them, seven hub genes were identified, including ALB, FN1, EGF, PTGS2, PLG, KDR, and LOX. Three hub genes, ALB, EGF, PLG, exerted a direct action on glomerulus. GO enrichment analysis of DEGs was mainly manifested in extracellular matrix organization, extracellular structure organization, platelet degranulation and other biological processes, extracellular matrix, secretory granule lumen, platelet alpha granule and other cell components, chaperone binding, copper ion binding, antioxidant activity, and other molecular functions. DEGs mainly regulated metabolic process, which was related to fatty acid degradation signal pathway, exogenous substance metabolism related to CYP enzyme and drug metabolism signal pathway.Conclusion:A bioinformatics analysis of DN from the perspective of glomerulopathy is helpful to understand the potential molecular mechanism of DN and provide reference for further validation.

OBJECTIVE: To analyze the anatomical and developmental characteristics of nasal sinuses in 1-2 years old children; and provide potential evidence for the diagnosis and treatment of sinusitis in 1-2 years old children. METHOD: Coronal CT scans of 60 cases (1-2 years old children) were studied with the imaging station. Reference datas were identified on these images using imaging station. The gasification conditions of the sinuses were identified and measured. RESULT: 100% of the frontal sinuses were not developed, while 100% of the maxillary sinuses were developed. The mean of the transverse and vertical diameters for the left side of the maxillary sinuse was (13.32 ± 2.88) mm and (13.55 ± 2.43) mm, respectively. While those for the right side were (13.63 ± 2.75) mm and (13.59 ± 2.13) mm, respectively. The anterior and posterior ethmoid sinuses were 100% developed. The mean transverse and vertical diameters for the left side of the anterior ethmoid sinus were (3.94 ± 0.86) mm and (11.92 ± 1.67) mm, respectively. While those mean for its right side were (3.88 ± 0.88) mm and (12.18 ± 1.86) mm, respectively. The mean transverse and vertical diameters for the left side of the posterior ethmoid sinus were (6.02 ± 1.07) mm and (10.51 ± 1.43) mm, respectively. While those for the right side were (5.91 ± 1.20) mm and (10.51 ± 1.55) mm, respectively. 88.3% (106 sides) of the sphenoid sinuses were developed, while 11.7% (14 sides) were not developed. The mean transverse and vertical diameters for the left side of the sphenoid sinus were (5.18 ± 2.15) mm and (5.78 ± 1.86) mm, respectively. While those for the right side were (4.91 ± 2.24) mm and (5.89 ± 2.03) mm, respectively. CONCLUSION The nasal sinuses in 1-2 years old children have been already developed. The development of the maxillary and ethmoid sinuses was clear and definite. The pneumatization of the sphenoid sinus was defined in many babies; however, the pneumatization of the frontal sinus was not defined in all babies. Acute rhinosinusitis in 1-2 years old children is not uncommon. Therefore, definite diagnosis and positive treatment of such cases are essential for avoidance of serious complications.
