Background Previous studies on telemedicine interventions have shown that older diabetic patients experience difficulty in using computers, which is a barrier to remote communication between medical teams and older diabetic patients. However, older people in China tend to find it easy to use mobile phones and personal messaging apps that have a user-friendly interface. Therefore, we designed a mobile health (mHealth) system for older people with diabetes that is based on mobile phones, has a streamlined operation interface, and incorporates maximum automation. Objective The goal of the research was to investigate the use of mobile phone–based telemedicine apps for management of older Chinese patients with type 2 diabetes mellitus (T2DM). Variables of interest included efficacy and safety. Methods A total of 91 older (aged over 65 years) patients with T2DM who presented to our department were randomly assigned to one of two groups. Patients in the intervention group (n=44) were provided glucometers capable of data transmission and received advice pertaining to medication, diet, and exercise via the mHealth telemedicine system. Patients assigned to the control group (n=47) received routine outpatient care with no additional intervention. Patients in both groups were followed up at regular 3-month intervals. Results After 3 months, patients in the intervention group showed significant ( P <.05) improvement in postprandial plasma glucose level. After 6 months, patients in the intervention group exhibited a decreasing trend in postprandial plasma glucose and glycated hemoglobin levels compared with the baseline and those in the control group ( P <.05). Conclusions Mobile phone–based telemedicine apps help improve glycemic control in older Chinese patients with T2DM.

Aims Metformin treatment for type 2 diabetes mellitus (T2DM) can be limited by gastrointestinal (GI) adverse events (AEs), resulting in treatment discontinuation. We investigated whether once‐daily metformin extended release (XR) is superior in terms of GI tolerability, with non‐inferior efficacy, compared with thrice‐daily metformin immediate release (IR) in treatment‐naïve Chinese patients with T2DM. Materials and Methods This prospective, open‐label, randomized, multicentre, phase IV interventional study enrolled Chinese T2DM patients to receive either metformin XR or metformin IR with a 2‐week screening period, a 16‐week treatment period and a 2‐week follow‐up period without treatment. Co‐primary endpoints were a non‐inferiority assessment of metformin XR vs metformin IR in glycated haemoglobin (HbA1c) least squares mean (LSM) change from baseline to week 16 and the superiority of GI tolerability for metformin XR vs metformin IR. Results Overall, 532 patients were randomized to metformin IR (n = 267) or metformin XR (n = 265). The HbA1c LSM change was −1.61% and −1.58% in each group, respectively (LSM difference, 0.03; 95% confidence interval [CI], −0.10, 0.17). Incidences of drug‐related AEs were 26.5% (n = 66) in the metformin IR‐only group and 32.2% (n = 85) in the metformin XR‐only group, and GI AEs were 23.8% and 22.3% in each group, respectively (difference, −1.52; 95% CI, −8.60, 5.56). The treatment difference met the predefined non‐inferiority upper CI margin of 0.4% in HbA1c. Conclusions Metformin XR was non‐inferior to metformin IR for the LSM change in HbA1c from baseline to week 16 and not superior to metformin IR for overall GI AE incidence during treatment of Chinese T2DM patients.
We studied the protective effect of stromal cell-derived factor-1β (SDF-1β) on cardiac cells from lipotoxicity in vitro and diabetes in vivo. Exposure of cardiac cells to palmitate increased apoptosis by activating NADPH oxidase (NOX)–associated nitrosative stress and endoplasmic reticulum (ER) stress, which was abolished by pretreatment with SDF-1β via upregulation of AMP-activated protein kinase (AMPK)–mediated p38 mitogen-activated protein kinase (MAPK) phosphorylation and interleukin-6 (IL-6) production. The SDF-1β cardiac protection could be abolished by inhibition of AMPK, p38 MAPK, or IL-6. Activation of AMPK or addition of recombinant IL-6 recaptured a similar cardiac protection. SDF-1β receptor C-X-C chemokine receptor type 4 (CXCR4) antagonist AMD3100 or CXCR4 small interfering RNA could not, but CXCR7 small interfering RNA completely abolished SDF-1β’s protection from palmitate-induced apoptosis and activation of AMPK and p38 MAPK. Administration of SDF-1β to diabetic rats, induced by feeding a high-fat diet, followed by a small dose of streptozotocin, could significantly reduce cardiac apoptosis and increase AMPK phosphorylation along with prevention of diabetes-induced cardiac oxidative damage, inflammation, hypertrophy, and remodeling. These results showed that SDF-1β protects against palmitate-induced cardiac apoptosis, which is mediated by NOX-activated nitrosative damage and ER stress, via CXCR7, to activate AMPK/p38 MAPK–mediated IL-6 generation. The cardiac protection by SDF-1β from diabetes-induced oxidative damage, cell death, and remodeling was also associated with AMPK activation.
Total aralosides of Aralia elata (Miq) Seem (TASAES) from Chinese traditional herb Longya Aralia chinensis L was found to improve cardiac function. The present study was to determine the protective effects of TASAES on diabetic cardiomyopathy, and the possible mechanisms. Therefore, a single dose of streptozotocin was used to induce diabetes in Wister rats. Diabetic rats were immediately treated with low, medium and high doses of TASAES at 4.9, 9.8 mg/kg and 19.6 mg/kg body weight by gavage, respectively, for eight weeks.
Type 1 diabetes mellitus (T1DM) is a long-term and chronic autoimmune disorder, in which the immune system attacks the pancreatic β-cells. Both adaptive and innate immune systems are involved in T1DM development. Both B-cells and T-cells, including CD4+ and CD8+ T-cells, as well as other T-cell subsets, could affect onset of autoimmunity. Furthermore, cells involved in innate immunity, including the macrophages, dendritic cells, and natural killer (NK) cells, could also accelerate or decelerate T1DM development. In this review, the crosstalk and function of immune cells in the pathogenesis of T1DM, as well as the corresponding therapeutic interventions, are discussed.
Gingival overgrowth (GO) includes gingival enlargement and hyperplasia and may be induced by certain drugs, including calcium channel blockers (CCBs), particularly first-generation CCBs. However, to date, only few cases of GO induced by second- or third-generation CCBs have been reported. The present study reports on a case of a 48-year-old diabetic male who was admitted to the First Hospital of Jilin University (Changchun, China) due to poor blood glucose control. This patient was diagnosed with GO. Review of the patient's medical history revealed diagnoses of type 2 diabetes and hypertension, as well as the use of felodipine, a second-generation CCB, to control hypertension. The hypertensive drugs were replaced and the new drugs helped the patient control his blood glucose levels. Additionally, the patient was instructed on methods he could use to improve his oral hygiene, including rinsing of the teeth following each meal and increasing the frequency of tooth brushing per day. After 3 months, the clinical symptoms of GO were relieved. The relevant literature was also reviewed to gain an improved understanding of the correlation between GO and CCBs, as well as diabetes and poor oral hygiene.
Backgroud: By reviewing the previous research of telemedicine, we have found out that old diabetic patients have difficulties in using computers, so it is unrealistic for medical teams to communicate with old diabetes patients anytime and anywhere. However, the popularity of smartphones and chatting applications has enabled old people of China to develop skills of chatting on smartphones and become familiar with smartphone operations. Therefore, we have designed an Mobile Health (m-Health) system for diabetics based on smartphones, which greatly streamlined operation interface and functions for maximum automation.In addition, the smartphone-based telemedicine of diabetes has been designed for old people.Objective: To investigate smartphone-based telemedicine applications in the management of older Chinese patients with type 2 diabetes mellitus (T2DM).Variables of interest included efficacy and safety.Methods: A total of 91 older (age>65) patients with T2DM, who presented to our department, were included and randomly assigned to one of two groups.Patients in the intervention group (n=44) were given glucometers capable of data transmission, and received advice pertaining to medications, diet, and exercise via a m-Health telemedicine system. Patients assigned to the control group (n=47) presented to traditional outpatient clinics for their medical care and received no other interventions. We followed up patients in both groups at regular 3-month intervals.Results: After 3 months, patients in the intervention group had significant (P<0.05) improvements in postprandial plasma glucose levels. After 6 months, patients in the intervention group exhibited decreasing trends in postprandial plasma glucose and glycosylated hemoglobin (HbA1C) levels compared with the baseline and those in the control group (P<0.05). Conclusions:Smartphone-based telemedicine applications are effective for controlling blood glucose and lowering HbA1C in older Chinese patients with T2DM.
