Design of remote diabetes management system based on dynamic blood glucose monitoring / 医疗卫生装备

Objective To design a remote diabetes management system based on dynamic blood glucose monitoring to solve the problems of traditional diabetes patient management in glucose data manual collection,unidirectional information flow and out-hospital glucose management.Methods A remote diabetes management system was developed with Java EE distributed microservices-based architecture and front-end and back-end separation mode,which used Vue for the front-end user interface design and IntelliJ IDEA development tools supporting Java language for the backend.The system developed was composed of a doctor App,a patient App and a background management terminal.The doctor App had three modules for user management,data viewing and intervention follow-up,the patient App had three modules for data monitoring,event recording and doctor-patient communication and the background management terminal had three modules for user management,data management and device management.Results The system developed realized individualized intervention and long-term glucose control based on real-time data acquisition of patient glucose fluctuation,diet,medication,exercise and other conditions.Conclusion The system developed can be used for the centralized online and offline management for in-hospital and out-hospital diabetes patients,which reduces the incidence of adverse events due to high or low blood glucose and improves the efficiency of medical staffs.[Chinese Medical Equipment Journal,2023,44(9):42-48]

Caprylic Acid Improves Lipid Metabolism, Suppresses the Inflammatory Response and Activates the ABCA1/p-JAK2/p-STAT3 Signaling Pathway in C57BL/6J Mice and RAW264.7 Cells / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to investigate the effects of caprylic acid (C8:0) on lipid metabolism and inflammation, and examine the mechanisms underlying these effects in mice and cells.@*METHODS@#Fifty-six 6-week-old male C57BL/6J mice were randomly allocated to four groups fed a high-fat diet (HFD) without or with 2% C8:0, palmitic acid (C16:0) or eicosapentaenoic acid (EPA). RAW246.7 cells were randomly divided into five groups: normal, lipopolysaccharide (LPS), LPS+C8:0, LPS+EPA and LPS+cAMP. The serum lipid profiles, inflammatory biomolecules, and ABCA1 and JAK2/STAT3 mRNA and protein expression were measured.@*RESULTS@#C8:0 decreased TC and LDL-C, and increased the HDL-C/LDL-C ratio after injection of LPS. Without LPS, it decreased TC in mice ( P < 0.05). Moreover, C8:0 decreased the inflammatory response after LPS treatment in both mice and cells ( P < 0.05). Mechanistic investigations in C57BL/6J mouse aortas after injection of LPS indicated that C8:0 resulted in higher ABCA1 and JAK2/STAT3 expression than that with HFD, C16:0 and EPA, and resulted in lower TNF-α, NF-κB mRNA expression than that with HFD ( P < 0.05). In RAW 264.7 cells, C8:0 resulted in lower expression of pNF-κBP65 than that in the LPS group, and higher protein expression of ABCA1, p-JAK2 and p-STAT3 than that in the LPS and LPS+cAMP groups ( P < 0.05).@*CONCLUSION@#Our studies demonstrated that C8:0 may play an important role in lipid metabolism and the inflammatory response, and the mechanism may be associated with ABCA1 and the p-JAK2/p-STAT3 signaling pathway.

Handgrip Strength as a Predictor of Nutritional Status in Chinese Elderly Inpatients at Hospital Admission / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To assess nutritional status and define gender- and age-specific handgrip strength (HGS) cut-point values for malnutrition or nutritional risk in elderly inpatients.</p><p><b>METHODS</b>A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening (NRS 2002) and Subjective Global Assessment (SGA) were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender- and age-specific receiver operating characteristic (ROC) curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves (AUCs) were calculated.</p><p><b>RESULTS</b>According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg (65-74 years) and 21.0 kg (75-90 years) for men and 17.0 kg (65-74 years) and 14.6 kg (75-90 years) for women. According to SGA, the optimal HGS cut-points were 24.9 kg (65-74 years) and 20.8 kg (75-90 years) for men and 15.2 kg (65-74 years) and 13.5 kg (75-90 years) for women.</p><p><b>CONCLUSION</b>Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.</p>
