Objective To investigate the application value of quantitative relaxation parameters based on synthetic MRI technology in the differential diagnosis of parotid gland tumors.Methods Conventional MRI and synthetic MRI data of 59 patients with patho-logically confirmed parotid gland tumors were analyzed retrospectively.T1,T2,and proton density(PD)values of the tumor were extracted from T1,T2 and PD mapping.The differences in quantitative relaxation parameters of pleomorphic adenomas,Warthin tumors,and malignant tumors were further compared.Diagnostic performance of each quantitative relaxation parameter was assessed and com-pared via receiver operating characteristic(ROC)curve and DeLong test.Results T2 value was significantly higher in pleomorphic adenomas than that in malignant tumors(P<0.05).The T1,T2,and PD values of pleomorphic adenomas and malignant tumors were significantly higher than those of Warthin tumors(P<0.05).The area under the curve(AUC)of the T2 value in differentia-ting pleomorphic adenomas from malignant tumors was 0.794.The AUC for T1 value(0.939)in differentiating Warthin tumors from malignant tumors was significantly higher than that of T2(0.873,P=0.341)and PD(0.927,P=0.891)values,without sta-tistically significant difference.The AUC for T2 value(0.968)in differentiating pleomorphic adenomas from Warthin tumors was significantly higher than that of T1(0.931,P=0.360)and PD(0.876,P=0.120)values,without statistically significant difference.Conclusion Quantitative relaxation parameters based on synthetic MRI technology may contribute to differentiating pleomorphic adenomas,Warthin tumors,and malignant tumors of the parotid gland.

African swine fever(ASF)is a virulent,hemorrhagic disease of swine caused by African swine fever virus(ASFV),which seriously affects the healthy development of Chinese pig indus-try.The genome of ASFV is large and encodes more than 165 proteins.Among them,the p54 pro-tein is encoded by the E183L gene,which has various functions such as participating in viral as-sembly,inducing apoptosis and inducing immune response.The conventional Chinese vaccine(C-strain)is a safe and effective attenuated vaccine developed by Chinese scientists.It can efficiently protect against attacks from various genotypes of classical swine fever virus(CSFV).The aim of this study was to investigate whether C-strain can express ASFV p54 protein serve as a delivery vector for ASF genetically engineered vaccines.An infectious clone of pHCLV-p54 was constructed by homologous recombination,the recombinant virus rHCLV-p54 was rescued by transfecting it into SK6 cells by blind passaging.Its genetic stability and growth curve were determined in vitro,while rabbits were immunized to evaluate its immunity effect.The results showed that the E183L gene remained genetically stable in the recombinant virus,indicating that the E183L gene could be stably inherited in recombinant viruses,but the inserted exogenous gene affected the replication of the C-strain.The results of the rabbit immunization test showed that the recombinant virus rHCLV-p54 was able to induce ASFV-specific antibodies.The above results indicated that we have successfully constructed a recombinant C-strain that stably expresses the ASFV p54 protein.In summary,the recombinant virus rHCLV-p54 has a good immunogenicity and is warranted for fur-ther evaluation as a vaccine candidate.
