Objective: To investigate the epidemiological characteristics of influenza outbreaks in Zhejiang Province from 2013 to 2022, so as to provide insights into influenza prevention and control. Methods: Data pertaining to influenza outbreaks reported in Zhejiang Province from 2013 to 2022 were collected from National Influenza Surveillance System in China, including time, region, cases and pathogen types of influenza outbreaks. The temporal, spatial and pathogen distribution of influenza outbreaks were analyzed using a descriptive epidemiological method. Results: A total of 577 influenza outbreaks involving 448 698 individuals were reported in Zhejiang Province from 2013 to 2022, and the overall attack rate was 5.34% (23 974 cases), with no death reported. The lowest attack rate of influenza was 0.26%, and the highest was 80.00%, with a median attack rate of 10.89% (interquartile range, 24.26%). The outbreak had the shortest duration of 1.00 day, and the longest duration of 59.00 days, with a median duration of 9.00 (interquartile range, 11.00) days. There were 387 influenza outbreaks that occurred between November and January of the following year (67.07%), and the three highest numbers of outbreaks were reported in Hangzhou City (310 outbreaks), Wenzhou City (51 outbreaks) and Jinhua City (46 outbreaks). There were 395 outbreaks reported in urban regions (68.46%), 93 in counties and townships (16.12%) and 89 in rural regions (15.42%), and influenza outbreaks predominantly occurred in primary schools (487 outbreaks, 84.40%). In addition, the types of pathogens were alternately prevalent, with influenza B virus (241 outbreaks, 41.77%) and A/H3N2 virus (232 outbreaks, 40.21%) as predominant subtypes. Conclusions Influenza outbreaks mainly occurred in winter in Zhejiang Province from 2013 to 2022, and primary schools were main places of influenza outbreaks, while influenza B virus and A/H3N2 virus were predominant subtypes. It is necessary to reinforce the surveillance and report of influenza-like illness in schools and improve the coverage of influenza vaccination to prevent influenza outbreaks.

Objective Post-transcription RNA interference (RNAi) is more and more widely applied in multigene therapy.This study aimed to establish an subcutaneous xenotransplanted tumor (SXT) model of human HT-29 colon carcinoma in nude mice and investigate the effects of the survivin shRNA-APC double gene co-expression lentiviral vector on the growth of SXT.Methods Thirty-five nude mice were equally divided into five groups, double-gene survivin shRNA, survivin shRNA, APC, empty vector, and blank, and injected into the left anterior axillary with respective stably transfected cell lines and human HT-29 colon carcinoma cells, all at 2×106/mL, to establish an SXT model of human HT-29 colon carcinoma.The inhibition rate of tumor growth was calculated by measuring the size and weight of the SXT, the expressions of survivin mRNA and protein in the tumor tissue detected by real time PCR and immunohistochemistry respectively, and the apoptosis of the HT-29 colon carcinoma cells determined by TUNEL.Results The mean size and weight of the SXT were significantly reduced in the double-gene survivin shRNA-APC, survivin shRNA, and APC groups as compared with the blank and empty vector groups (P<0.05), though increased in the survivin shRNA and APC groups in comparison with the double-gene group (P<0.05).The expressions of survivin mRNA and protein in the tumor tissue were remarkably lower in the double-gene survivin shRNA-APC, survivin shRNA, and APC groups than in the blank and empty vector groups (P<0.05), even lower in the double-gene group than in the survivin shRNA, and APC groups (P<0.05).The apoptosis rate of the HT-29 colon carcinoma cells was markedly up-regulated in the double-gene survivin shRNA-APC ([56.72±3.17]%), survivin shRNA ([33.64±2.03]%), and APC groups ([31.19±1.79]%) as compared with the blank ([9.89±0.31]%) and empty vector groups ([10.06±0.43]%) (P<0.05), even more significantly in the double-gene than in the survivin shRNA and APC groups (P<0.05).Conclusion The survivin shRNA-APC double gene co-expression lentiviral vector can reduce the expression level the survivin gene, promote the apoptosis of colon carcinoma cells, and suppress the growth of the subcutaneous xenotransplanted tumor.
