Objective To investigate noise management-associated behavioural intentions of ICU nurses and identify the factors that influence the intentions under the framework of the Theory of Planned Behaviour so as to provide references for proposing a noise management programme for ICU. Methods Objective sampling method was used to conduct semi-structured interviews with 17 ICU nurses in our hospital. The interview data were analysed with the method of Colaizzi seven-step analysis to extract themes. Results A total of 3 themes and 9 sub-themes were extracted. The themes together with the sub-themes included:the different behaviours and attitudes of ICU nurses (actively controlling noise sources,negatively responding to noise management);being influenced by multifaceted subjective norms (engaging in active management after noise event,responding to patient requests and team reminders and supervision);and limited perceptual behavioural control (require improvement in noise management,lack of knowledge in noise management,complex work scenarios lead to the neglect of noise management,and lack of training in noise management). Conclusion It is found that while ICU nurses generally hold a positive attitude towards noise management,there are still many challenges in the implementation process. ICU nursing staff are recommended to improve the awareness of the importance of noise management,establish the noise management system,conduct relevant training,and to develop a systematic,comprehensive and sustainable noise management strategy,therefore to reduce ICU noise levels and improve the hospital experience of the patients.

To observe the therapeutic effect of Nitazoxanide(NTZ) on dogs infected with Giardia canis trophozoites.Eight dogs were infected with Giardia canis trophozoites and divided into four groups rondomly,G1:2 dogs treated with Nitazoxanide at a single dose of 1 mg/kg body weight;G2:2 dogs treated with NTZ at a single dose of 2 mg/kg;G3:2 dogs treated with NTZ at a single dose of 41 mg/kg;G4:2 dogs treated without drugs as control.All groups were examined for Giardia canis cysts by Zinc Sulfate Flotation.Each group was subjected to collect stool per day and counted cysts.The results of G2 and G3 were negative after 1th day.G1 were negative after 4th days.The results indicated that NTZ at a dose of 2 mg/kg and 4 mg/kg in dogs had a faourable effect on the dogs infected with Giardia canis.
