The amino acid sequences of the OmpA protein isolated from Escherichia coli QML2206-1(E.coli QML2206-1)in our laboratory were analyzed for homology with different strains of OmpA proteins using bioinformatics software,and the OmpA protein was analyzed for its physicochemical properties,transmembrane structure and signal peptide prediction,B-cell anti-genic epitope prediction,secondary and tertiary structure prediction.The OmpA gene fragment was ligated with pET-32a vector to construct a prokaryotic expression vector,which was purified by a nickel column affinity purification system after prokaryotic expression and optimization of ex-pression conditions in BL21(DE3).The purified recombinant protein was fully mixed with Freund's adjuvant to immunize mice,and the levels of mouse-specific IgG antibody and the expression levels of cytokines CD4,CD8 and IL-4 in mouse serum were detected by ELISA,and the immuno-protective effect was evaluated by mouse attack protection test.OmpA protein is a hydrophilic protein with no transmembrane structural domains and a secondary structure consisting mainly of irregular coils(47.98％)and α-helices(29.77％),with 12 antigenic epitopes that can bind to anti-bodies produced by B cells.The recombinant protein OmpA with a relative molecular mass of a-bout 55 kDa was successfully obtained by prokaryotic expression,and the highest expression was induced by IPTG concentration of 0.000 4 mmol/L for 6 h at 37 ℃.The serum-specific IgG anti-body potency of recombinant protein immunized mice was up to 1∶32 000;the expression levels of CD4,CD8 and IL-4 in the serum of immunized mice were elevated compared with those of the con-trol group.The survival rate of mice was 80％and 40％after attack with minimum lethal dose(MLD)and 2 times minimum lethal dose(2MLD),respectively.OmpA recombinant protein has good antigenicity and certain immunoprotective effects,and this study provides a technical basis for the next step in the development of a genetically engineered subunit vaccine against yak-appli-cable E.coli based on OmpA protein.

In recent years,the prevalence of porcine infectious pleuropneumonia caused by Actinoba-cillus pleuropneumoniae(APP)has significantly increased in large-scale pig farms in China.The i-solation,identification,and biological characteristic testing of newly prevalent strains have impor-tant clinical significance.This study isolated four suspected APP strains(named XB2T-56,JMTLP-443,YD-THB-755,SYZJ-291)from lung samples of pig farms suspected of outbreaks of porcine infectious pleuropneumonia in Hubei Province.They were identified by PCR amplification,and multiplex PCR serological typing,the biological properties were tested by detecting the growth a-bility,hemolytic activity and biofilm forming ability.The drug resistance of the strains was ana-lyzed by drug sensitivity testing,and the virulence of one strain(XB2T-56)in mice and piglets was evaluated.The PCR identification result showed that all four clinical isolates were APP serotype 15 strains.These four strains grew slower than serotype 1 standard strains,had weaker hemolytic activity,but could form stronger biofilms.These strains are all less sensitive to cephalosporin,tylo-sin,sulfamethoxazole,and doxycycline,but sensitive to cefotaxime and enrofloxacin.The mice and piglet infection experiments showed that the isolated strain XB2T-56 has strong virulence.Artifi-cial intranasal infection causes acute death in piglets,with typical symptoms of pleuropneumonia in the lungs,and serotype 15 strains can be isolated from the lesion site.This study indicates that the APP serotype 15 strain has strong virulence,providing new date for the clinical epidemiological characteristics of APP.

Objective:To explore the protective effect of knock-down the expression of B lymphocyte induced maturation protein 1(Blimp1)gene on early liver injury in carbon tetrachloride(CCl4)-induced mouse model of liver fibrosis.Methods:C57BL/6 mice were intraderitoneal injected with 5％CCl4 olive oil solution to create mouse model of hepatic fibrosis.The expression of Blimp1 gene in the mice was re-duced by intraderitoneal injection of short hairpin RNA(shRNA)adeno-associated virus(AAV).The mice were randomly divided into 3 groups:blank test group(n=10),CCl4+AAV-shRNA-NC group(n=10)and CCl4+AAV-shRNA-Blimp1 group(n=10).After 27 days of preparation of the CCl4 mouse model,animal materials were carried out.Western blot and real-time PCR were used to detect the levels of Blimp1,α-smooth muscle actin(α-SMA),collagen type Ⅰ alpha 1(COL1A1),collagen typeⅢ alpha 1(COL3A1),and their mRNA expression levels of liver tissue in each group.The serum of each group was separated to measure aspartate transaminase(AST)and alanine transaminase(ALT)by automatic biochemical analyzer.The pathological changes of liver tissue and the degree of liver fibrosis in the mice were detected by pathological staining including hematoxylin-eosin staining,Masson,and Sirius red.Results:The expression levels of Blimp1 protein in the liver of CCl4+AAV-shRNA-NC group(2.036±0.244,t=3.690,P=0.002)were significantly increased than that of the blank test group.In the CCl4+AAV-shRNA-Blimp1 group,the expression of Blimp1 protein decreased to the basal level(0.783±0.249,t=6.223,P=0.003).Compared with the serum levels of ALT[(1 957.8±633.6)U/L]and AST[(1 808.8±260.1)U/L]in the CCl4+AAV-shRNA-NC group,the serum levels of ALT[(894.0±360.1)U/L,t=3.998,P=0.003]and AST[(820.0±100.6)U/L,t=6.141,P=0.004]in the CCl4+AAV-shRNA-Blimp1 group were significantly decreased.The pathological re-sults of the CCl4+AAV-shRNA-Blimp1 group showed that compared with the CCl4+AAV-shRNA-NC group,the infiltration of inflammatory cells in the liver tissue was reduced and the degree of fibrosis was alleviated.The level of α-SMA(0.676±0.064,t=7.930,P=0.001),COL1A1(1.426±0.143,t=6.364,P=0.003)and COL3A1(1.124±0.198,t=3.440,P=0.026)of liver in the CCl4+AAV-shRNA-Blimp1 group were significantly decreased than that of CCl4+AAV-shRNA-NC group,and the mRNA expression levels were altered as well as their protein levels.Conclusion:Blimp1 plays an important role in CCl4-induced liver fibrosis in mice,and knock-down the expression of Blimp1 gene is beneficial to protect early liver injury in mice.

Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.
