Qualitative research methods are becoming more and more important in medical research area. Some qualitative researches played important roles in the exploration and the spread of core ideas of Chinese medicine. The report of qualitative research should be transparent and credible according to the standardized report criterion. On the basis of 22 criteria, the Consolidated Criteria for Reporting Qualitative Research (COREQ) was developed and published in September 2007. This introduction to COREQ will be helpful to Chinese qualitative researchers and readers in the implementation of high quality of medical qualitative research in China.

Objective The purpose of this study was to explore the impact of consistency primary nursing model on improvement of obstetric nursing care quality.Methods The sample consisted of 230 postpartum women in the intervention group and the other 240 postpartum women in the control group of non-intervention.The intervention is the use of new model of consistency primary nursing.Women finished the scale of overall patient satisfaction before their delivery.The other data of obstetric nursing care quality score were collected by study staff for three months.Data were analyzed using t test.Results Score of patients' overall satisfaction and obstetric nursing care quality in the invention group were much higher than that of the control group except for first-aid articles and disinfection and isolation.Conclusions The consistency primary nurs-ing model resulted in higher satisfaction and nursing care quality standard.It is suggested to extend this new nursing model in most maternity and infant hospitals and other general hospitals.

Objective: To analyze influencing factors of in-stent restenosis after coronary artery stent implantation, to provide theoretical support for clinical prevention of restenosis. Methods: Clinical data of 123 patients, who received coronary artery stent implantation in our hospital from Mar 2011 to Sep 2013 and received coronary angiography follow-up one year after operation, were retrospectively analyzed. In-stent restenosis was regarded as stenosis of inner diameter of implanted stent≥50%, so patients were divided into restenosis group (n=35) and non-restenosis group (n=88). Multi-factor Logistic regression analysis was used to analyze influencing factors of coronary in-stent restenosis. Results: Compared with non-restenosis group, there were significant reductions in serum level of total bilirubin [(14.02±6.76) μmol/L vs. (10.90±4.51) μmol/L] and stent diameter [(3.06±0.86) mm vs. (2.87±0.44) mm] in restenosis group, P<0.01 both. Multi-factor Logistic regression analysis indicated that blood glucose level was independent risk factor for restenosis after coronary artery stent implantation (OR=2.545, P=0.035), while stent diameter and serum level of total bilirubin were its protective factors (OR=0.857, 0.850, P<0.05 both). Conclusion: Blood glucose level is an independent risk factor for restenosis after coronary artery stent implantation, while stent diameter and serum level of total bilirubin are its protective factors.
