Objective To rapidly evaluate the efficacy,safety,and economics of dexmedetomidine in patients on mechanical ventilation in intensive care unit(ICU),and to provide references for clinical and decision makers.Methods To search PubMed,Embase,Cochrane Library,CNKI,WanFang Data databases and official websites of domestic and foreign Health Technology assessment(HTA)institutions from the inception to June 14,2023.HTA reports,systematic reviews/Meta-analyses,and pharmacoeconomic studies of patients with mechanical ventilation in ICU compared with dexmedetomidine versus placebo or other traditional sedatives were included.Two reviewers independently identified studies,extracted data,assessed the quality of included studies,and descriptive analyzed and summarised the results.Results A total of 13 literatures were included,including 10 systematic reviews/Meta-analyses and 3 economic studies.The analysis results of effectiveness showed that compared with placebo or other traditional sedatives,the use of dexmedetomidine in the sedation of mechanically ventilated patients in the ICU was associated with a shorter duration of mechanical ventilation and a shorter length of stay in the ICU.The analysis results of safety displayed treatment with dexmedetomidine could reduce the incidence of delirium,but may increase the incidence of bradycardia.The results of the economic analysis showed that the dexmedetomidine group had a higher cost of medication,but a lower overall ICU cost.Conclusion Dexmedetomidine has good efficacy,safety and economics in the sedation of patients on mechanical ventilation in ICU,but the economic studies included in the search were mainly foreign studies,and domestic economy studies needs to be further demonstrated.

A 77-year-old female patient with type 2 diabetes mellitus mistakenly injected insulin aspart 16 U subcutaneously as glargine insulin before bedtime.One hour later,she developed slow response and paraphasia.Her urgent blood glucose level was 2.8 mmol/L.An Ⅳ injection of 50％ glucose injection 40 ml,mask oxygen absorption,and continuous ECG monitoring were given immediately.Thirty minutes later,her blood glucose level increased to 8.4 mmol/L.The adjusted hypoglycemic regimen was subcutaneous injection of 8,10,and 8 units of insulin aspart 15 minutes before 3 meals,respectively,and glargine insulin 18 U before bedtime.Six days later,her fasting and 2-hour postprandial blood glucose levels were 7.0-8.3 mmol/L and 9.1-10.2 mmol/L,respectively.

OBJECTIVE:To provide reference for improving the quality of talent training for medical direction of chain man-agement major in higher vocational college. METHODS:The situation of pharmaceutical retail chain industry market was analyzed in China;the problems of talent training mode were summarized to put forward reform plan and measures according to disadvantag-es. RESULTS:Based on the market situation as continues expansion of pharmaceutical retail chain industry market scale,shortage of professional talent pool,the formulation of new retail mode in China,and training mode situation as not enough in-depth cooper-ation between college and enterprise,poor practicality and pertinence of course setting,irrational teachers'structure,teaching re-form could be conducted on the basis of modern apprenticeship system in following aspects,such as college and enterprise shared the responsibility of training and cultivating,student admission is recruitment;college and enterprise designed curriculum system and assessed students together;double tutorteam of college teacher and enterprise teacher was constructed. CONCLUSIONS:The talent training mode based on modern apprenticeship system is the entry point for teaching reform of medical direction of chain management major in higher vocational college,which is conducive to cultivate high quality pharmaceutical management talents meeting industry needs and social development.
