In order to survey the prevalence of encephalomyocarditis virus (EMCV) infection in pigs in Hebei Province from 2006 to 2008,a total of 1306 swine serum from 31 farms in 10 regions in Hebei were tested for antibodies against EMCV nonstructural protein 2C by ELISA.Positive rates of antibodies in different regions and different age groups were analyzed.The results showed that antibodies against EMCV 2C were found in 176 out of 1306 serum samples collected from Hebei Province and the total positive rate was 13.48%.Seroprevalence of EMCV infection appeared in six out of ten surveyed regions and the highest positive rate was 26%.There was significant difference of seroprevalence in EMCV infection between breeder sows and other swine species.This survey indicated that EMCV infection has occurred in pig farms in most regions of Hebei Province and EMCV-carried breeder sows were one of the crucial causes for EMCV infection and prevalence.

ObjectiveTo investigate the application value of narrative medical model in communication with cancer patients with low education level. MethodsRetrospective analysis was performed on 80 cancer patients with low education level who were hospitalized in West China Hospital of Sichuan University from March 2019 to April 2020. They were randomly divided into control group （n=40） and observation group （n=40）. The control group received conventional nursing intervention， while the observation group received narrative medical nursing mode intervention. Both groups received intervention for 6 months. The Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS）， Morisky Medication Adherence Scale （MMAS-8）， Social Support Rating Scale （SSRS） and self-designed knowledge of the disease and cognition questionnaire were used for evaluation before and after intervention. ResultsAfter intervention， the SAS and SDS scores of observation group were lower than those of control group （t=7.493， 8.314， P<0.01）. After intervention， medication compliance of observation group was higher than that of control group （χ²=4.012， P=0.045）. SSRS subscale score and total score were higher than those in control group （t=2.198， 7.548， 2.664， 4.248， P<0.05 or 0.01）. After intervention， the mastery rate of knowledge about the disease and the excellent and good rate of cognitive behavior in observation group were higher than those in control group （χ²=4.588， 5.541， P<0.05）. ConclusionThe narrative medical model is of certain application value in communication with cancer patients with low education level. It can better improve the patients’ negative emotions， social support， and knowledge and cognition of the disease.
