Objective To investigate the correlation between BMI and insulin dose in diabetic patients after short-term continuous subcutaneous insulin infusion (CSII). Methods Three hundred patients with type 2 diabetes mellitus (T2DM) were enrolled and randomized into the normal weight (BMI < 23 kg/m2) group, overweight (BMI 23 ~ 25 kg/m2) group and obesity (BMI≥25 kg/m2) group. The metabolic and anthropometric parameters of each group were compared and the related factors which may influence insulin dose were analyzed. Results The insulin dose per weight in the overweight group or in the obesity groups was significantly lower than that in the normal weight group. Weight and BMI were negatively correlated with the insulin dose per weigh. Conclusions Differences of glycemia level , β-cell function and insulin resistance exist in Chinese type 2 diabetes patients with different BMI. The stratification of BMI should be considered before estimating the insulin dose by body weight in CSII therapy.

Objective:To design a new medication guidance tool for clinical intravenous therapy and nursing safety which covers all-dimensional information of intravenous therapy and nursing needs, and observe its application effects.Methods:(1) The treatment plans of common and frequently-occurring diseases in the priority departments of Class Ⅲ general hospitals in Jilin Province from January 2016 to December 2017 were retrospectively investigated and summarized to determine the index framework of intravenous therapy guidance tools. (2) The status quo survey, expert meeting and literature search were used to determine the content of the guidance tool and the drug information. (3) The expert consensus was used to determine the presentation of the guidance tool. (4) Totally 127 nurses in the departments were selected by convenient sampling for a non-contemporaneous controlled trial to compare the effects of the guidance tool after one month of application and nursing staff's level of knowledge about the risk of intravenous therapy.Results:(1) A guidance tool with 8 specialties, 73 treatment plans, and 326 commonly used drug information presented with specialties as an index and visualized signs was designed and developed, which covers relevant information such as requirements for infusion device materials, selection of infusion device, and requirements for inter-group tube flushing and sealing. (2) From May to June 2019, the nurses were tested before and after use, who were required to complete the specialist drug knowledge questionnaire within the specified time. The accuracy of the three dimensions of the physical and chemical properties of drugs, pharmacological effects, and safe use was 89.76%, 90.55%, and 95.27%, respectively, which were higher than that before use, and the difference was statistically significant ( P<0.05) . Conclusions:Based on the needs of clinical intravenous therapy and nursing safety medication, the novel guidance tool for intravenous therapy and safe medication nursing is designed and completed, which can effectively improve the nurses' ability to safely use intravenous medications and work efficiency and is worth promoting in clinical practice.
