Objective The effect and application value of the treatment of Graves eye disease were discussed.Methods 82 patients with Graves ophthalmopathy were divided into observation group and control group by random number method . The control group was given hormone therapy , the observation group was given methylprednisolone combined with methotrexate therapy .The clinical effect was compared between the two groups . Results The total effective rate of the observation group was 87.80％,which was significantly higher than 68.29％of the control group(χ2 =4.555,P<0.05).After treatment,the thyroid volume,eye level of the observation group were (24.68 ±1.25) g,(17.13 ±1.01) mm,respectively,which of the control group were (28.84 ±2.89) g, (18.79 ±2.12)mm,respectively,and the differences between the two groups were statistically significant (t=8.459, 4.526,all P<0.05).In the observation group,there were 2 cases of diabetes,1 case of hypertension,4 cases of insomnia,4 cases with digestive tract.In the control group,1 case of diabetes,2 cases of hypertension,5 cases of insomnia,3 cases of gastrointestinal tract ,and the differences between the two groups were not statistically significant (χ2 =0.346,0.346,0.124,0.156,all P>0.05).Conclusion Methylprednisolone combined with methotrexate in the treatment of Graves ophthalmopathy can improve the treatment effect , reduce the degree of exophthalmus and thyroid volume,and without increase in adverse reactions ,it is worthy of popularization and application in clinic .

Objective:To analyze and reveal the genetic evolution and variation of influenza viruses in cases of co-infection in Guangdong Province.Methods:Throat swab samples were collected from four cases of H1N1pdm and H3N2 co-infection for viral isolation. The isolated strains were subjected to antigen analysis and neuraminidase inhibitor susceptibility test. High-throughput sequencing was used to detect the sequences of strains in three throat swab samples and one virus strain, and then genetic variations were analyzed.Results:Four influenza viruses were isolated with one strain of H1N1pdm and three of H3N2 subtype, and all of them were genetically similar to the vaccine strain in 2022-2023. The HA genes of H1N1pdm and H3N2 strains belonged to clade 6B.1A.5a.2a and 2a.3a.1, respectively. The isolated strains belonged to the same clade as the strains prevalent in Guangdong during the same period. No drug-resistant variations were detected in N1 or N2 gene, and the isolated strains were sensitive to oseltamivir and zanamivir.Conclusions:H1pdm subtype had stronger replication ability than H3 subtype in the influenza viruses isolated from co-infected cases. H1N1pdm and H3N2 subtype influenza viruses were genetically similar to the strains circulating in Guangdong at the same time. The isolated H1N1pdm and H3N2 strains were sensitive to both oseltamivir and zanamivir, indicating that they could continue to be used in the treatment of influenza virus infections caused by one or two genotypes.
