Flash glucose monitoring system in patients with type 1 diabetes in healthcare center in Brazil: real world data from a short-term prospective study

ABSTRACT Objectives: To evaluate the alternate use of flash glucose monitoring (FGM) with self-monitoring blood glucose (SMBG), in patients with type 1 diabetes (T1D). Materials and methods: Two weeks of open FGM (P2), both preceded (P1) and followed by 2 weeks (P3) of SMBG with a blinded FGM system. Mean absolute relative difference (MARD) was calculated by (-FGMi − SMBGi-) / SMBGi, where it was a paired data sample. Results: In total, 34 patients were evaluated. Time in range (TIR) did not change between P1 and P2. In 12 patients (35.3%), TIR increased from 40% at P1 to 52% at P2 (p = 0.002) and in 22 (64.7%), TIR decreased or did not change. FGM use resulted in decreased % time spent in hypoglycemia (<70 mg/dL) (6.5% vs. 5.0%; p = 0.005), increased % time spent in hyperglycemia (>180 mg/dL) (44.5% to 51%; p = 0.046) with no significant change in % TIR. The proportion of patients who reached sensor-estimated glycated hemoglobin (eA1c) < 7% decreased from 23.5% at P1 to 12.9% at P2, p = 0.028. For the whole sample, the MARD between the two methods was 15.5% (95% CI 14.5-16.6%). For normal glucose range, hyperglycemic levels and hypoglycemic levels MARD were 16.0% (95% CI 15.0-17.0%), 13.3% (95% CI 11.5-15.2%) and 23.4% [95% CI 20.5-26.3%)], respectively. Conclusion: FGM after usual SMBG decreased the % time spent in hypoglycemia concomitant with an undesired increase in % time spent in hyperglycemia. Lower accuracy of FGM regarding hypoglycemia levels could result in overcorrection of hypoglycemia.

Impact of insulin injection induced lipohypertrophy on multidimensional glucose variability in patients with type 1 diabetes mellitus / 中华内分泌代谢杂志

Objective:This study aimed to investigate the effect of lipohypertrophy induced by insulin injection on blood glucose fluctuation in patients with type 1 diabetes mellitus.Methods:A total of 80 patients with type 1 diabetes mellitus were recruited between June 2021 and December 2021 from the First Affiliated Hospital of Nanjing Medical University. And these patients all received insulin injection more than six months. Lipohypertrophy was assessed by ultrasound scanning, and blood glucose fluctuation was evaluated using the flash glucose monitoring system(FGM). Univariate analysis and multivariate linear regression were used to analyze the relationship of lipohypertrophy and and core indicators of blood glucose fluctuation.Results:Compared with patients without lipohypertrophy, patients with lipohypertrophy had higher mean amplitude of glycemic excursions(MAGE), coefficient of variation(CV), mean of daily differences(MODD), standard deviation(SD) of blood glucose, time above range(TAR), and high blood glucose index(HBGI; all P<0.05), while time in range(TIR) of glucose markedly become lower( P<0.01). Moreover, multivariate linear regression analysis showed that lipohypertrophy detected by ultrasound was an independent influencing factor of TIR( β=-9.423, P=0.032), MAGE( β=1.114, P=0.039), CV( β=4.304, P=0.041), MODD( β=0.717, P=0.046) after adjusting for age at diagnosis, duration of insulin injection, fasting C-peptide, and daily dose of insulin per unit weight. Conclusion:Lipohypertrophy increases glycemic variability and imposes negative impact on glycemic control rate in patients type 1 diabetes mellitus.

Relationships of habitual daily alcohol consumption with all-day and time-specific average glucose levels among non-diabetic population samples

BACKGROUND@#Alcohol consumption is a prevalent behavior that is bi-directionally related to the risk of type 2 diabetes. However, the effect of daily alcohol consumption on glucose levels in real-world situations in the general population has not been well elucidated. This study aimed to clarify the relationship between alcohol consumption and all-day and time-specific glucose levels among non-diabetic individuals.@*METHODS@#We investigated 913 non-diabetic males and females, aged 40-69 years, during 2018-2020 from four communities across Japan. The daily alcohol consumption was assessed using a self-report questionnaire. All-day and time-specific average glucose levels were estimated from the interstitial glucose concentrations measured using the Flash glucose monitoring system for a median duration of 13 days. Furthermore, we investigated the association between all-day and time-specific average glucose levels and habitual daily alcohol consumption levels, using never drinkers as the reference, and performed multiple linear regression analyses after adjusting for age, community, and other diabetes risk factors for males and females separately.@*RESULTS@#All-day average glucose levels did not vary according to alcohol consumption categories in both males and females. However, for males, the average glucose levels between 5:00 and 11:00 h and between 11:00 and 17:00 h were higher in moderate and heavy drinkers than in never drinkers, with the difference values of 4.6 and 4.7 mg/dL for moderate drinkers, and 5.7 and 6.8 mg/dL for heavy drinkers. Conversely, the average glucose levels between 17:00 and 24:00 h were lower in male moderate and heavy drinkers and female current drinkers than in never drinkers; the difference values of mean glucose levels were -5.8 for moderate drinkers, and -6.1 mg/dL for heavy drinkers in males and -2.7 mg/dL for female current drinkers.@*CONCLUSIONS@#Alcohol consumption was associated with glucose levels in a time-dependent biphasic pattern.

Aplicación de la Telemática en el monitoreo remoto de Bancos de Muestras Biológicas. Estudio Preliminar

Las serotecas son espacios destinados para el resguardo de Muestras Biológicas (MB) de procesos diagnósticos y científicos. El Instituto de Investigaciones en Ciencias de la Salud (IICS) cuenta con ocho congeladores de Ultra Baja Temperatura (UBT) distribuidos en dos serotecas. El sistema de monitoreo diseñado se evaluó durante cuatro meses, mientras registraba y enviaba alertas de tres UBT instalados en una de las serotecas y de su temperatura ambiente. Se recabó información de los usuarios respecto al rango de las temperaturas de cada UBT, tipo de MB almacenadas y su criterio de conservación. Se emplearon controladores de temperatura con sensores PT 100 conectados a un convertidor RS485/Ethernet en cada congelador. El sistema monitoreó, registró y alertó vía correo electrónico a los usuarios y técnicos biomédicos sobre los incidentes por temperaturas fuera del rango y falla de comunicación. En total se registraron 25 incidentes, 17 referentes al tiempo de apertura de puerta, 5 por temperatura elevada del ambiente y 3 por problemas en la conexión de red. La aplicación de la telemática fue determinante para monitorear en tiempo real las temperaturas de los congeladores UBT y del ambiente para garantizar que la cadena de frío no se vea afectada. De esta forma se cuenta con una herramienta que notifica a los usuarios de serotecas y biobancos los incidentes eléctricos o eventos que afecten el rango de temperatura necesario para la preservación de los materiales biológicos, permitiéndoles realizar una intervención oportuna y así garantizar la correcta preservación de las MB.

The serum banks are spaces used for the protection of Biological Samples (BS) of diagnostic and scientific processes. The Instituto de Investigaciones en Ciencias de la Salud (IICS) has eight Ultra Low Temperature (ULT) freezers distributed in two serum banks. The designed monitoring system was evaluated for four months, while recording and sending alerts of three ULTs installed in one of the serum banks and their ambient temperature. Information was collected from users regarding the temperature range of each ULT, type of stored BS and their conservation criteria. Temperature controllers with PT 100 sensors connected to an RS485/Ethernet converter were used in each freezer. The system monitored, recorded and alerted users and biomedical technicians via email about incidents due to temperatures outside the range and communication failure. In total, 25 incidents were recorded, 17 related to door opening time, 5 due to high ambient temperature and 3 due to network connection problems. The application of telematics was decisive in monitoring the temperatures of the ULT freezers and the environment in real time to ensure that the cold chain was not affected. In this way, there is a tool that notifies users of serum banks and biobanks of electrical incidents or events that affect the temperature range necessary for the preservation of biological materials, allowing them to perform a timely intervention and thus guaranteeing the correct preservation of the BS.

Factors influencing changes in total radioactivity in differentiated thyroid cancer patients after 131I treatment / 中华放射医学与防护杂志

Objective:To investigate the changes in total radioactivity in patient body with differentiated thyroid carcinoma (DTC) after 131I treatment and the factors influencing its metabolism. Methods:The clinical data from 218 patients after DTC treatment in the Department of Nuclear Medicine, the Second Affiliated Hospital of Air Force Medical University from September 2021 to April 2022 were retrospectively analyzed. Based on administrated 131I dose, 171 patients were divided into low-dose group (≤ 3.7 GBq) and 47 into high-dose group (>3.7 GBq) . A whole body dynamic radiation monitoring system was used to measure the in vivo residual activity of 131I 24, 48 and 72 h after 131I administration and to explore their influencing factors. Results:24, 48 and 72 h after adimination of 131I, the residual activity of 131I in the low-dose group patients was significantly lower than in the high-dose group patients ( t= -7.46, -3.31, -2.01, P<0.05) . The discharge compliance rate at 24 and 48 h in the low-dose group was significantly higher than that in the high-dose group (21.0% vs. 4.3%, 98.2% vs. 89.4%, χ2 = 7.23, 5.91, P<0.05) , and all patients could meet the discharge criteria at 72 h. Univariate analysis showed that the residual 131I activity at 24 and 48 h was dependent on age, body mass index (BMI) , basal metabolism rate (BMR) and thyroid stimulating hormone (TSH) . As have been shown by multiple linear regression analysis, in the low-dose group, the older age, the higher BMR and the higher TSH level at 24 h tended to the higher 131I residual activity in the body. At 48 h, the higher BMI and the higher TSH level lead to the higher 131I residual activity in patient body. Meanwhile, in the high-dose group, the higher age and BMR at 24 h, tended to the higher in vivo131I residual activity. The influencing factors were analyzed in terms that 131I residual activity reaching 400 MBq in patient body at 24 and 36 h. The result showed that at 24 h the lower TSH level leaded to the lower 131I residual activity in patient body. At 36 h, the younger age, the lower TSH level, and the smaller 131I treatment dose tended to the lower in vivo131I residual activity. Conclusions:Age, BMI, BMR and TSH levels are the influencing factors for the change in total activity in patient body after 131I treatment of DTC. Radiation dose assessment based on the above indicators can provide a reference for adjusting the length of hospitalization time.

Factors associated with glycemic variability in children with type 1 diabetes mellitus based on flash glucose monitoring system / 中南大学学报(医学版)

OBJECTIVES@#Patients with classical type 1 diabetes mellitus (T1DM) require lifelong dependence on exogenous insulin therapy due to pancreatic beta-cell destruction and absolute insulin deficiency. T1DM accounts for about 90% of children with diabetes in China, with a rapid increase in incidence and a younger-age trend. Epidemiological studies have shown that the overall glycated haemoglobin (HbA1c) and compliance rate are low in Chinese children with T1DM. Optimal glucose control is the key for diabetes treatment, and maintaining blood glucose within the target range can prevent or delay chronic vascular complications in patients with T1DM. Therefore, this study aims to investigate the glycemic control of children with T1DM from Hunan and Henan Province with flash glucose monitoring system (FGMS), and to explore factors associated with glycemic variability.@*METHODS@#A total of 215 children with T1DM under 14 years old were enrolled continuously in 16 hospitals from August 2017 to August 2020. All subjects wore a FGMS device to collect glucose data. Correlation of HbA1c, duration of diabetes, or glucose scan rates with glycemic variability was analyzed. Glucose variability was compared according to the duration of diabetes, HbA1c, glucose scan rates and insulin schema.@*RESULTS@#HbA1c and duration of diabetes were positively correlated with mean blood glucose, standard deviation of glucose, mean amplitude of glucose excursions (MAGE), and coefficient of variation (CV) of glucose (all P<0.01). The glucose scan rates during FGMS wearing was significantly positively correlated with time in range (TIR) (P=0.001) and negatively correlated with MAGE and mean duration of hypoglycemia (all P<0.01). Children with duration ≤1 year had lower time below range (TBR) and MAGE when compared with those with duration >1 year (all P<0.05). TIR and TBR in patients with HbA1c ≤7.5% were higher (TIR: 65% vs 45%, TBR: 5% vs 4%, P<0.05), MAGE was lower (7.0 mmol/L vs 9.4 mmol/L, P<0.001) than those in HbA1c >7.5% group. Compared to the multiple daily insulin injections group, TIR was higher (60% vs 52%, P=0.006), MAGE was lower (P=0.006) in the continuous subcutaneous insulin infusion group. HbA1c was lower in the high scan rates (≥14 times/d) group (7.4% vs 8.0%, P=0.046), TIR was significantly higher (58% vs 47%, P<0.001), and MAGE was lower (P<0.001) than those in the low scan rate (<14 times/d) group.@*CONCLUSIONS@#The overall glycemic control of T1DM patients under 14 years old in Hunan and Henan Province is under a high risk of hypoglycemia and great glycemic variability. Shorter duration of diabetes, targeted HbA1c, higher glucose scan rates, and CSII are associated with less glycemic variability.

Incidence of major autoimmune diseases of the nervous system in China / 中华神经科杂志

Autoimmune diseases of the nervous and muscle systems constitute a major disease category in neurology, characterized by high disability and heterogeneity. However, incidences for this group of disorders are still unknown in China at the national level. The emergence of the national Hospital Quality Monitoring System (HQMS) provides comprehensive data for epidemiological studies of rare diseases, and the systematism, accuracy and consistency during data collection of HQMS information provide a unique advantage for the investigation of the incidence of rare diseases. Currently, the incidence of major neurological autoimmune diseases based on HQMS has been accomplished and published. In conjunction with clinical practice and research progress of this field, the incidence studies of multiple sclerosis, neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis, Guillain-Barré syndrome, and myasthenia gravis are summarized. The completion of survey of disease incidence is instrumental to investigate the prevalence of this group of diseases. Ultimately, the outcome would benefit neurologists as well as health care policy makers.

Application of optical surface monitoring system in intra-fraction motion monitoring in frameless cranial stereotactic radiotherapy / 中华放射医学与防护杂志

Objective:To establish a novel clinical application process of the optical surface monitoring system (OSMS) in the cranial frameless stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT), and to assess the accuracy and effectiveness of the OSMS in the intra-fraction motion monitoring of both cranial phantoms and cranial SRT patients fixed using the Q-Fix encompass immobilization system.Methods:The deviations of OSMS in the real-time motion monitoring were assessed by determining the deviations between the displacement of the cranial SRS phantoms detected by the OSMS and the predefined displacement of the Varian Edge six degrees of freedom (6DoF) couch. The ability of the OSMS to conduct real-time monitoring of the head movement was also analyzed when one camera was blocked by the rotary gantry of the accelerator and when the couch was at non-zero angles. Moreover, ten patients who received 50 fractions of cranial frameless SRT were enrolled in this study. All the patients were fixed using the Q-Fix Encompass system, and their intra-fraction motion was monitored using the OSMS. The intra-fraction errors of OSMS real-time monitoring throughout the treatment were obtained from the OSMS logs. The patients received cone-beam computed tomography (CBCT) after the beam delivery, and the six-dimensional errors were obtained as intra-fraction motion errors of the CBCT.Results:For the cranial phantoms, there was a close correlation between the OSMS monitoring deviations and the predefined displacement in six dimensions. The OSMS-detected 3D vector deviations in the translational and rotational directions were (0.28±0.10) mm and (0.15±0.09)°, respectively when the angel both the gantry and couch was 0° and were (0.35±0.13) mm and(0.17±0.09)°, respectively, when one camera was blocked. The OSMS monitoring deviations with the couch at a non-zero degree were greater than those at zero degree. The maximum deviations occurred when the couch was at 270° and were (0.69±0.19) mm and (0.32±0.12)°, respectively, in the translational and rotational directions. For the cranial SRT patients fixed using the Q-Fix Encompass system, the OSMS and CBCT showed comparable intra-fractional motion deviations, which were (0.40±0.26) and (0.29±0.10) mm, respectively in the translational direction and were (0.33±0.20)°and (0.26±0.08)° in the rotational direction.Conclusions:The OSMS is an effective tool for optically guided radiotherapy, which allows for intra-fraction real-time motion monitoring with sub-millimeter accuracy. Therefore, to ensure the accurate preformation of cranial SRS/SRT, it is necessary to conduct the intra-fractional position monitoring using OSMS.

Objective:To retrospectively analyze the setup errors of thermoplastic head and shoulder molds alone or combined with vacuum pad in hypofractionated stereotactic radiotherapy (HFSRT) for non-small cell lung cancer (NSCLC) with brain metastases.Methods:Fifty-four NSCLC patients with brain metastases who received HFSRT from 2017 to 2019 were enrolled in this study. Twenty-four patients were fixed with thermoplastic head and shoulder molds (group A), and 30 patients were fixed with thermoplastic head and shoulder molds plus vacuum pad (group B). The interfraction and intrafraction setup errors were acquired from cone-beam CT online image registration before and after the HFSRT. Optical surface system was applied in monitoring the intrafraction setup errors. The setup errors in each direction between two groups were analyzed by independent samples t-test. Results:For the interfraction setup errors of the whole group, the proportion of the horizontal setup errors of ≥3mm was 7.0% to 15.4% and 7.0% to 12.6% for the rotation setup errors of ≥2°. In group A, the anteroposterior setup error was (1.035±1.180)mm, significantly less than (1.512±0.955)mm in group B ( P=0.009). In group A, the sagittal rotation setup error was 0.665°±0.582°, significantly less than 0.921°±0.682° in group B ( P=0.021). For the intrafraction setup errors of the whole group, the proportion of horizontal setup errors of ≥1mm was 0% to 0.7%, whereas no rotation setup error of ≥1° were observed. In group B, bilateral, anteroposterior and sagittal rotation setup errors were (0.047±0.212)mm, (0.023±0.152)mm and 0.091°±0.090°, significantly less compared with (0.246±0.474)mm, (0.140±0.350)mm and 0.181°±0.210° in group A ( P=0.004, P=0.020, P=0.001), respectively. Optical surface monitoring data were consistent with the obtained results. Conclusions:Thermoplastic head and shoulder molds (with or without vacuum pad) combined with online image registration and six-dimensional robotic couch correction can be applied in HFSRT for brain metastases from NSCLC. The intrafraction setup errors in group B are smaller than those in group A. Optical surface system has certain value in monitoring the intrafractional movement.

Objective: The objective of this study is to assess the clinical effect and safety of ultrasound-guided percutaneous microwave ablation (US-PMWA) assisted by three-dimensional (3D) visualization operative treatment planning system in larger adrenal metastasis (LAM) (D ≥ 4 cm). Materials and Methods: From Dec 2011 to Dec 2017, 12 consecutive LAM patients with pathologically proven with a mean diameter of 5.2±1.3cm (range 4.1-7.6) were treated. Artificial ascites and thermal monitoring system as ancillary technique were used. The patients were followed up with imagings and complications were recorded. Results: The median follow-up period was 31 months (ranged 6–52 m). All LAM achieved completely ablation according to the 3D planning preoperation. Complete ablation was achieved in 10 (10/12, 83.3%) patients by one session and 2 patients (2/12, 16.7%) by two sessions. Recurrence was detected at the treated site in 3 patients (3/12, 25.0%) at 5, 9, and 13 months after ablation and received another ablation. Progression of metastasis disease at extra-adrenal sites occurred in 9 patients (9/12, 75%). Seven (7/12, 58.3%) patients died during the follow-up period. Therefore, the 1-, 2-, and 3-year local tumor control rates were 83.3%, 75.0%, and 75.0%, and 1-, 2-, 3- and 4-year overall survival rates were 91.7%, 75.0%, 50.0%, and 41.7%, respectively. No severe complications related to ablation occurred, except 3 (3/12, 25%) patients developed hypertension during ablation. Conclusions: US-PMWA assisted by 3D visualization preoperative treatment planning system maybe a safe and efficient therapy for LAM, which could promote ablation precision, improve the clinical outcomes

Intelligent monitoring system assisted pelvic fracture closed reduction for treating one case with complex pelvic fracture / 中国修复重建外科杂志

Objective: To introduce the experience of intelligent monitoring system assisted pelvic fracture closed reduction to treat complex pelvic fracture in a minimally invasive method. Methods: A 30-year-old male patient with complex pelvic fracture caused by a falling injury was treated in December 2019. The pelvic fracture was diagnosed by X-ray film and CT three-dimensional reconstruction. The AO/Orthopaedic Trauma Association (AO/OTA) classification was 61-C3.3 type (H-shaped sacrum fracture with pubic symphysis separation). At 48 hours after injury, the vital signs were stable, and the operation was performed. The pelvic fracture was reduced with the help of pelvic reduction frame and skeletal traction, the intelligent monitoring system, and fixed with the channel screws. Results: The intraoperative blood loss was 50 mL, the operation time was 180 minutes, and the fluoroscopy time was 45 seconds. The incision healed well after operation. The X-ray film of pelvis was taken on the next day after operation, and the fracture reduction was evaluated as anatomical reduction according to Matta standard; CT three-dimensional reconstruction showed that the fixation screws were all located in the cortex of bone, without penetrating the cortex of bone.

Objective To investigate the effect of real-time continuous monitoring system(RT-CGMS)on serum inflammatory factors and prognosis in patients with sepsis.Methods According to the prospective studies,patients were randomly divided into two groups Patients with sepsis were randomly divided into real-time continuous monitoring of blood glucose group and monitoring blood glucose meter group,of which the fasting serum tumor necrosis factor alpha(TNF-α) and interleukin-6(IL-6) and high sensitive C reactive protein (hs-CRP) were detected on the 1st,3rd,7th day.Meanwhile,insulin dosage,incidence of hypoglycemia and mortality rate of 28 days of patients in two groups were recorded,and the above indexes were analyzed.Results TNF-α,IL-6 and hs-CRP in the real-time continuous blood glucose monitoring group were (16.12±2.42)pg/ml、(112.37±17.39)pg/ml and(19.62±2.72)mg/L on the 7th day respectively,while TNF-α,IL-6 and hs-CRP in the blood glucose monitoring group were(23.46±3.12)pg/ml、(140.19±21.48)pg/ml and(25.42±2.54)mg/L on the 7th day,respectively.The decrease of TNF-α,IL-6 and hs-CRP in the continuous blood glucose monitoring group was more significant than that in the blood glucose monitoring group (P＜0.05).Insulin dosage in real-time continuous blood glucose monitoring group was (90.62±15.79)u,hypoglycemia rate was 5.4％,fatality rate was 10.81％ in 28 days of hospitalization,insulin dosage was (130.59±20.65)u,hypoglycemia rate was 22.85％,and fatality rate was 31.42％ in 28 days of hospitalization.There was significant difference between the two groups(P＜0.05).Conclusion For sepsis patients with stress hyperglycemia,a real-time continuous monitoring system combined with insulin therapy can improve the inflammatory response,and control blood glucose effectively as well as reduce mortality.

Medication Adherence Using Electronic Monitoring in Severe Psychiatric Illness: 4 and 24 Weeks after Discharge

OBJECTIVE: The purpose of this study was to examine post-hospitalization outpatient drug adherence in patients with severe psychiatric illness, including bipolar disorder and schizophrenia, and to investigate factors associated with drug adherence. METHODS: Eighty-one patients diagnosed with schizophrenia or bipolar disorder who were hospitalized due to aggravation of psychiatric symptoms were monitored. At hospitalization, we conducted clinical assessments such as the Clinical Global Impression-Severity, Drug Attitude Inventory, Contour Drawing Rating Scale, Multidimensional Scale of Perceived Social Support scale, and patients' demographic factors. We measured drug adherence using the Medication Event Monitoring System (MEMS), pill count, and patients' self-report upon out-patients visits, 4 and 24 weeks after discharge. RESULTS: The mean values of the various measures of adherence were as follows: MEMS (4 weeks) 84.8%, pill count (4 weeks) 94.6%, self-report (4 weeks) 92.6%, MEMS (24 weeks) 81.6%, pill count (24 weeks) 90.6%, and self-report (24 weeks) 93.6%. The adherence agreement between MEMS, pill count, and self-report was moderate (4 weeks intra-class correlation [ICC]=0.54, 24 weeks ICC=0.52). Non-adherence (MEMS ≤0.08) was observed in 26.4% of the patients at 4 weeks and 37.7% at 24 weeks. There was a negative correlation between drug adherence assessed 4 weeks after discharge and Contour Drawing Rating Scale difference score (r=−0.282, p<0.05). A positive correlation was found between drug adherence assessed 24 weeks after discharge and Drug Attitude Inventory (r=0.383, p<0.01). CONCLUSION: Patients' attitude towards their medication and their degree of physical dissatisfaction influenced post-hospitalization drug adherence in severe psychiatric patients.

Design and Implementation of Rehabilitation Equipment Monitoring System Based on Web / 中国康复理论与实践

Objective:To design a web-based monitoring system for rehabilitation equipment in order to solve the problems of inadequate monitoring system for existing rehabilitation equipment and poor communication between doctors and patients. Methods:The system was composed of device communication layer, server layer and user access layer, which was implemented by B/S architecture. Rehabilitation equipment was connected with intelligent gateway through wireless communication module. HTTP protocol and socket communication technology were used to realize remote communication between rehabilitation equipment and platform server. The server layer mainly used MVC design pattern and J2EE technology, adopted the current popular Web framework SSM (Spring + Spring MVC + MyBatis) design, MySQL database was responsible for data storage. User access layer was designed with HTML5+JSP+Bootstrap+HighCharts+CSS+JavaScript+Ajax and other technologies. Results:By deploying the public network of the project, the remote monitoring experiment of the equipment was carried out. The upload of status information and the download of page control instructions could be responded in a short time interval. Considering the factors such as network delay, the design met the requirements. Conclusion:This system is simple to operate and efficient to transmiss data between platform and equipment. It can provide convenient service support for medical staff, patients and equipment administrators.
