ABSTRACT
Aimed at the importance and current situation of hospital medical equipment management, the paper has analyzed the method of application and advantages of two dimension code technology and intelligent terminal in the management of medical equipment. And the two dimension code conversion software, which was developed by using C++ language compiler software and medical equipment management system, could achieve two dimension code information conversion and label production of medical equipment for instruction, maintenance, meterage and scraping and other information. And the intelligent terminal couldbe used to obtain information in real time, and it could combine with the existed one dimensional code to achieve informationization management for medical equipment, and then gradually replace one dimensional code. Through discussed the advantages of two dimension code and compared with the traditional model, the results indicated that this technology could provide a new direction in developmental trends and application prospect, and enhance the management level for dynamic information, and solve the problems of inconvenience in updating information.
ABSTRACT
Objective To investigate the association of serum brain-derived neurotrophic factor (BDNF) and methylglyoxal (MG) levels with cognitive function in elderly patients with type 2 diabetes mellitus (T2DM). Methods The normal population and elderly patients with T2DM were frequency-matched by age, sex, and educational level. BDNF was detected by ELISA assay, MG by HPLC assay, and cognitive function by sets of repetitive mental state examination (RBANS) in the two groups. Results (1) Compared with control group, serum BDNF level in T2DM group was significantly decreased [ (4.97±3.05 vs 11.77±7.92)ng /ml, P<0.01]while serum MG level was elevated [(67.91 vs 43.86) nmol /L, P<0.05]. The increasing of serum MG was related to the decreasing of serum BDNF. (2) Compared with control group, the scores for standardized tests of cognitive scale, visual breadth, immediate memory, delayed memory, and attention areas in T2DM group were significantly decreased (all P<0.05). After the influencing factors were adjusted by multiple regression, the associations of serum BDNF level with cognitive scale standardized score, the delay associated with memory and attention functions were still evident, and serum MG level in T2DM group was still related with the levels of delayed memory, immediate memory, total scale standardization (all P<0.05). (3) Serum BDNF level was negatively correlated with serum MG level (P=0.031). Conclusions Cognitive function of elderly patients with T2DM is related with serum MG and BDNF levels. The increased serum MG as well as the decreasd serum BDNF levels maybe involved in the pathogenesis of impaired cognitive function.
