Objective To construct the gall-stone patients' nursing workload measurement project by Delphi method,so as to measure single disease workload scientifically and reasonably.Methods The gall-stone patients' nursing workload measurement project were designed on the basis of consulting literature and experts discussion,then two rounds of consultations were made with experts by using the Delphi method.Results The valid recovery rate of questionnaires of two rounds consultations were all 100％ (22/22).The expert authority coefficient was 0.886 1.Nursing workload measurement project,directly related to the gall bladder calculi 54 nursing projects,including technical 46,unskilled 7;indirectly related to the gall bladder calculi 36 nursing projects,including technical 17,unskilled 19.Conclusions The measurement project of gall-stone patient determined by Delphi method has high reliability,which is significant to the scientific measuring of nursing single disease workload.

Objective To assess the effects of management by diabetes specialist nurse (DSN) on blood glucose control.Methods A comprehensive search of databases was carried out including PubMed,the Cochrane Library,Web of Science,China National Knowledge Infrastructure (CNKI),Chinese Biomedical Literature Database (CBM),China Scientific Journal Database (VIP) and Wanfang Database from their inception to November 2013 in any language to identify trials.Searching of relevant publications was undertaken to identify additional trials.Randomized controlled trials and quasi-randomized controlled trials dealing with the effects of management by DSN on glycosylated hemoglobin (HbA lc) were included in the review.Two investigators performed data extraction and quality assessment independently.Statistic analysis were carried out using RevMan5.2 software.Results Eighteen trials were included finally.Meta-analysis showed that management by DSN can better control the blood glucose of patients(WMD=-0.63,95％CI-0.88--0.38),but the effect was influenced by intervention time,location and type of the diabetes mellitus.Conclusions The presence of a DSN can improve patients' blood glucose control,especially in the long-term control of blood glucose.

Objective In order to measure the nursing unit workload scientifically,we used the Delphi method to investigate the influencing factors of nursing unit workload.Methods After consulting literature and discussing with experts,alternative indicators were designed,then two rounds of consultations were made with experts by using the Delphi method.Results The questionnaires revealed that the valid recovery rate,after two rounds of consultations,were 95％ and 100％ respectively,which reflected the positivity of the experts which participated in this study.The expert authority coefficient was 0.896,which indicated the high reliability of the consulting.The coordination indexes of expert opinions were 0.467 and 0.239 respectively,which showed the expert advices had good coordination and the results had high reliability.Conclusions The influencing factors of nursing unit workload determined by Delphi method have high reliability,which is significant for the scientific measuring of the nursing unit workload.

Objective The visualization analysis system was used to explore the development context,research hotspots,and trends of diabetes-related cognitive dysfunction,providing a reference for subsequent studies and new ideas.Methods The literature on cognitive impairment in diabetes mellitus was retrieved from the Web of Science Core collection database from October 2022,and visualized by Citespace 6.1.R3.Results A total of 6448 English literature were included,and the annual number of publications showed an overall increasing trend.America posted the most,and the top 10 are dominated by authors from these America and China.Research focuses on the pathogenesis and risk factors of cognitive impairment in diabetes mellitus.Conclusion Understanding the risk factors of cognitive impairment in diabetic patients,early intervention is helpful to reduce the incidence of diabetic cognitive impairment,so as to prevent,delay and slow down the occurrence of cognitive impairment more effectively.

OBJECTIVETo optimize the methods for genetic detection and prenatal diagnosis of Duchenne muscular dystrophy (DMD).

METHODSDenaturing high-performance liquid chromatography (DHPLC), multiplex PCR (mPCR), sequencing and other molecular techniques were used in combination for molecular diagnosis of 8 cases diagnosed as DMD.

RESULTSAmong the 8 cases, 4 have carried large deletions, 3 have point mutations, among which 6 were of de novo type. Prenatal diagnosis were offered for 5 families, the results showed that none of the fetuses had carried large deletions or point mutations. The pregnancies had continued and healthy babies were born.

CONCLUSIONCombined use of short tandem repeat, DHPLC, mPCR and sequencing can improve the detection of DMD gene mutations. By establishing and optimizing genetic and prenatal diagnostic methods, accurate genetic counseling can be provided for families affected with DMD.
