Objective To investigate the research status of head nurses of 10 secondary hospitals in Yichang area,to understand the research attitudes and intentions,to provide a reference basis for further research training program.Methods A total of 161 head nurses in 10 secondary hospitals in YiChang were recruited and a questionnaire survey was conducted.Results There are 11.7％ of head nurse involved in research projects,44.7％ of them did not publish paper,and 80％ of them had never received scientific research knowledge and training in school.95.1％ of head nurse think the nursing research is very important,and willing participate in research study,69.6％ of them want to take part in the practical activity.Conclusions The foundation for research in Head nurse is weak inthe secondary hospital with low research achievements,however they have shown a positive scientific attitude,that may improve research ability,the hospital should pay attention to the head nurse research needs,provide effective training,promote nursing research capacity.

Objective The aim of this article is to research the radical mastoidectomy and primary tympanoplasty to attain radical cure of the mastoid focus as well as rebuilding the sound- conducting structure of the tympanic cavity to improve the audition. Method The autobone and temporal fascia were taken as the transplants after the radical mastoidectomy under microscopy, and then to carry out the operation of Portmann｀ s tempanoplasty of 2nd and 3rd types of 2nd class.Result Non of the cholesteatoma was relapsed after follow- up for 1～ 4 years.The efficiency rate of tympanoplasty is of 89.47% .The average audition increased was 19 dB HL. Conclussion Radical operation for cholesteatoma should be associated with tympanoplasty if having condition. We recommend that the opening tympanoplasty should be used, and use autobone as a artificial auditory ossicles.

Objective To analyze the difference of macular retinal thickness between normal subjects and diabetic patients without retinopathy,and discuss the relationship between macular thickness and the course of diabetes,blood glucose level.Methods Twenty-two cases of patients with diabetic without retinopathy without retinopathy in our hospital of fourth Department of Internal medicine from April 2016 to November 2016 were selected as diabetic without retinopathy group,and another 22 normal pemons were selected as the normal group.The central subfield retinal thickness (CSRT),cube volume(CV) and cube average thickness(CAT) of all patients were determined by optical coherence tomography (OCT),and the difference of CSRT,CV and CAT between diabetic patients and normal group were analyzed.Then,the patients with diabetic retinopathy were sub-grouped according to the course of diabetes (group A,B,C,) and blood glucose status (group D and E),and the differences of CSRT,CV and CAT among them were compared.Results With the increase of diabetes duration in the diabetic without retinopathy group,CSRT,CV and CAT were gradually increased,and there was significant difference (P ＜ 0.05).With rising blood sugar in diabetics in the diabetic without retinopathy group,CSRT,CV and CAT were gradually increased,and there was significant difference (P ＜ 0.05).There were positive correlation between CSRT,CV,CAT and course,blood sugar of diabetes mellitus (all P ＜ 0.05).Conclusion Compared with normal population,CSRT,CV and CAT are significantly thickened in diabetes mellitus patients,and CSRT,CV and CAT are increased gradually with the increase of diabetes and blood glucose,which provide reliable reference for the diagnosis of early diabetic retinopathy.
