Objective To investigate the detection rate,epidemiology and resistance mechanism of methicil-lin-resistant Staphylococcus aureus(MRSA)in a hospital in recent 5 years.Methods A total of 762 strains of non repetitive Staphylococcus aureus detected from 2016 to 2020 in a hospital were collected retrospectively.Methicillin-sensitive Staphylococcus aureus(MSSA)was 392 strains(MSSA group)and 370 strains caused by MRSA(MRSA group),and 95 strains of MRSA isolated in 2020 were further used for resistance mechanism.Staphylococcus aureus was identified and tested for drug sensitivity by Vitek 2 automatic microbial system.Molecular epidemiological typing was determined by multilocus sequence typing.The biofilm formation was performed by crystal violet staining.PCR amplification was used to detect drug resistance genes,virulence genes and biofilm related genes,and logistic regression analysis was used to investigate the independent risk factors of its occurrence.Results The detection rate of MRSA in past five years was 48.56%,mainly was from pus samples and secretion samples(38.38%,33.51%respectively).MRSA was found in the general sur-gery(18.65%)and otorhinolaryngology(12.70%).ST88 was the most common multilocus sequence typing(37.89%),and followed by ST951(24.21%).Moderate biofilm formation was the most common,accounting for 74.73%.Multivariate regression analysis showed that compared with MSSA group,hypoproteinemia,en-docrine system diseases,wound infection and history of antibiotic use within six months were the independent risk factors for infection in MRSA group.Compared with the control group,hospital transfer,wound infection and tumor were independent risk factors for infection in MRSA group(P<0.05).Conclusion The detection rate of MRSA in a hospital is high,and the carrying rate of various drug-resistant genes is high.The hospital should pay attention to the prevalence of MRSA and related risk factors,so as to prevent it early.

Objective To explore the effects of the motivational interview on medication adherence and control level of asthma in adult patients with asthma. Methods A total of 100 asthma patients who were hospitalized in the Respiration Department of Putuo People's Hospital in 2016 were selected in the study using convenience sampling. According to the random number table, the participants were divided into the observation group (n=50) and the control group (n=50). Two cases from the observation group withdrew from the study due to personal reasons, leaving 48 patients in the observation group. Three cases from the control group withdrew from the study (i.e. two for disease changes and one for personal reasons), leaving 47 cases in the control group. The control group received conventional health education while the observation group received education based on motivational interview. The asthma medication compliance scale (Chinese version) (MARS-A) and asthma control test (ACT) questionnaire were used to evaluate the medication compliance and asthma control level before the intervention and 1, 2 and 3 months after the intervention. Results None of the patients had good medication compliance before the intervention. However, patients in the observation group had significantly better adherence at 1, 2, and 3 months after the intervention compared with the control group (P<0.05). There were no significant differences in asthma control level between two groups before intervention (P>0.05). But after the intervention, the repeated variance analysis showed that there were significant differences in both intervention effect and time effect for asthma control score, and the interaction effects existed between intervention and time (P< 0.05). Conclusions The health education based on motivational interview can effectively improve the medication adherence and the control level of asthma in adult patients with asthma.
