Objective To analyze the mammographic features of invasive lobular carcinoma (ILC)compared to those of invasive ductal carcinoma (IDC).Methods Twenty cases with ILC and 95 cases with IDC were retrospectively evaluated by two breast radi-ologists according to the Breast Imaging Reporting and Data System (BI-RADS)lexicon.The mammographic findings were com-pared between ILC and IDC with the independent samples chi-square test or Fisher’s exact test,as appropriate.Results Mass was the most common finding in both ILCs and IDCs,but less frequent in ILCs (36.4% vs 63.9%,P =0.008).Mass in ILCs was more frequently lobular or irregular shape with spiculated margin.Architectural distortion and focal asymmetry were more frequent in ILCs than in IDCs,however,the differences were no significant.The frequency of calcifications was not significantly different between the two groups.The distributions of calcifications were more regional in ILCs,and more segmental or linear in IDCs (P =0.01).Conclu-sion ILCs are more usually shown as non-mass appearances on mammography.ILCs that appeared as mass are more frequently ir-regular in shape with spiculated margins.

One influenza H3N2 virus, A/swine/Shandong/3/2005 (Sw/SD/3/2005), was isolated from pigs with respiratory disease on a farm in eastern China. Genetic analysis revealed that Sw/SD/3/2005 was a triple-reassortant virus with a PB2 gene from human-like HIN1, NS from classical swine H1NI, and the remaining genes from human-like H3N2 virus. These findings further support the concept that swine can serve as reservoir or mixing vessels of influenza virus strains and maintain genetic and antigenic stability of viruses. Furthermore, we have successfully established a reverse genetics system based on eight plasmids and rescued Sw/SD/3/2005 through cell transfection. HI tests and RT-PCR confirmed that the rescued virus maintained the biological properties of the wild type Sw/SD/3/2005. The successful establishment of the reverse genetics system of Sw/SD/3/2005 will enable us to conduct extensive studies of the molecular evolution of H3N2 influenza viruses in swine.

Abstract: Objective　To explore the regional, age and annual characteristics of distribution and variation trend of children and adolescents with poor vision in Hainan Province, and to provide a theoretical basis for the formulation of targeted and effective prevention and treatment strategies. Methods　The eyesight monitoring data of 5 657 231 children and adolescents aged 6 to 19 from 17 cities and counties in Hainan Province from 2013 to 2020 were analyzed. Using the "Standard Logarithmic Vision Chart" (GB11533-2011) that complies with national standards for testing. Results　The rate of poor vision among children and adolescents in Hainan Province increased significantly from 2013 to 2020, and the difference between the years was statistically significant (P<0.001). The total poor vision rate in the left eye increased 10.09% (32.79% to 42.88%), and that of severe poor vision rate increased 6.68%, while that of the right eye increased 9.80% (33.11% to 42.91%) and 6.49%. The poor vision rate was significantly higher in females than in males of same year (P<0.001), but the increase pattern was the same. In 2020, there were significant differences between the same age groups in different cities and counties and between different age groups in the same city and county (P<0.001), and they all tended to increase with age. The result of analyzing the distribution characteristics of the total poor vision rate of different age groups children in the eastern (Qionghai), southern (Sanya), western (Changjiang), northern (Haikou) and central (Dingan) cities showed that the regional rate difference was small at 6-7 years old, and then increased with the increase of age. The poor vision rate of Haikou City ranked the first in all age groups, and reached the highest at 17 years old, with 76.32% and 80.89% of total poor vision rate of left and right eyes respectively. Sanya City ranked second, Qionghai ranked third. The poor vision rate of Changjiang County was lower and the growth rate was slower according to age. Conclusions　From 2013 to 2020, the total and severe poor vision rates in left and right eyes of children aged 6-19 in Hainan Province increased year by year, with the ascension range of female higher than that of male, and right eye higher than that of left eye. In the same year, the poor vision rate increase rapidly with age. It is recommended to further strengthen the daily intervention and management of key populations and special age groups to reduce the rate of low vision in children and adolescents.
