Qualitative research has made important contributions to nursing practice and theory construction.Based on the authors'rich experiences in conducting and teaching qualitative studies,this paper proposed some suggestions on the use of qualitative research,writing and quality evaluation of qualitative research papers.It aims to deepen the understanding of nursing researchers to qualitative research,so as to improve the quality of qualitative research in nursing papers.

Objective To compare the clinical efficacy and safety of carbon dioxide (CO2) versus high-frequency electroacupuncture based on the assistance of drilling and blunt dissection in the treatment of steatocystoma multiplex.Methods A randomized,self-controlled study was performed in 15 patients.The median line of the body served as the dividing line,and the lesions on the two sides of the median line of the body were randomly divided into 2 groups to be treated with CO2 laser or high-frequency electroacupuncture,which left micropathways into the cyst cavity.After the above treatment,contents in the cysts were squeezed out or drawn out with a mosquito clamp,and the cysts were bluntly dissected.The decrustation time,erythema subsiding time,adverse reactions and recurrence were compared among lesions at different sites or with different sizes.Results For the lesions at the same sites or with similar sizes after treatment,the decrustation time and erythema subsiding time were both significantly shorter in the CO2 laser group than in the high-frequency electroacupuncture group (both P ＜ 0.05).There were significant differences in the decrustation time and erythema subsiding time among lesions at different sites or with different sizes (all P ＜ 0.05).Mild pain occurred in the 2 groups,and no hematoma or secondary infection occurred.There were significant differences in the incidence of scar formation or pigmentation between the 2 groups (both P ＜ 0.05).During the follow-up of 6-18 months,relapse occurred in 1 patient in each group.Conclusion Compared with the high-frequency electroacupuncture,CO2 laser assisted by drilling and blunt dissection shows better efficacy in the treatment of steatocystoma multiplex,and it can remove lesions at various sites at one time.

Objective To deeply understand the psychological experience of patients with primary tumors participating in clinical trials,providing a reference basis for meeting the psychological needs of patients and improving the mental health level of patients with primary tumors.Methods From November 2021 to May 2022,13 patients with primary tumors participating in clinical trials were selected by target sampling method,semi-structured interviews were conducted,with Colaizzi 7-step analysis method was used to analyze the data.Results Four themes were extracted from the psychological experience of patients,namely the perception and attitudinal experience of clinical trials,complex and changeable emotional responses,experimental process adaptation,personal growth and transformation.Conclusion The psychological experience and related psychological problems of primary tumors patients participating in clinical trials cannot be ignored,the research team needs to help them complete role transformation and adaptation,pay attention to the experience of patients,improve mental health education programs according to the needs of this type of patients,and improve the quality of life of patients,then promote the development of cancer diagnosis and treatment in China.
