Ninety-one patients over 60 year old with type 2 diabetes mellitus(T2DM) were selected from our outpatient department. The patients of experimental group uploaded their blood glucose data detected with glucometers, and obtained integrated management called " Mobile Health(M-health)" management such as medicines,diet,exercise from medical groups. The patients of control group got medical care in a traditional way without receiving other interventions. Regular follow-up was conducted in 2 groups every 3 months. The results showed that 3 months later,postprandial 2h plasma glucose in the experimental group was significantly improved compared with that of control group (P<0.05). Six months later, postprandial 2h plasma glucose and HbA1Clevels in the experimental group showed a decline comparing to the baseline, showing a statistical significance compared with control group(P<0.05). These results suggest that smartphone-based telemedicine is helpful of blood glucose control in elderly T2DM patients.

Objective To investigate the mechanism of rapamycin inhibiting the differentiation and proliferation of newborn porcine pancreatic adult stem cells, and to explore the therapeutic methods that may effectively reduce the side effects of rapamycin. Method Porcine NPCCs were treated with rapamycin alone or in combination with IGF-Ⅱ, and the caspase-3 and [ 3 H ]-thymidine uptake assays were performed to detect apoptosis and proliferation. The expression of insulin, PDX-1, NeuroD/Beta2, and Foxo1, a downstream transcription factor of IGF-Ⅱ, were analyzed by RT-PCR and Western blot to evaluate the differentiation ability of pancreatic adult stem cells. Results The NPCCs treated with rapamycin inhibited the proliferation ofβ-cells, increased apoptosis, reduced insulin secretion, inhibited the expression of PDX-1 and NeuroD/Beta2, and decreased the expression of IGF-Ⅱ. Foxo1 expression and induction of Foxo1 from the cytoplasm to the nucleus of the ectopic. The combined treatment of rapamycin and IGF-Ⅱcan reduce the side effects of rapamycin, inhibit the decrease ofβ-cell number and insulin content, repair the expression of insulin, PDX-1, NeuroD/Beta2, inhibit Foxo1 expression and intracellular ectopic. Conclusion Aberrant expression of IGF-Ⅱ and Foxol genes is the key inducing factor of rapamycin inhibiting the proliferation and differentiation of NPCCs, and IGF-Ⅱtreatment can effectively reduce the side effects of rapamycin on NPCCs differentiation.

Objective:To learn about the condition of Keshan disease at township level in Inner Mongolia Autonomous Region (Inner Mongolia for short).Methods:In accordance with the "Three-Year Tackling Implementation Plan for Keshan Disease in Inner Mongolia", Keshan disease surveillance was carried out from March to December 2019 in the disease affected townships of all 12 diseased banners (counties, cities, disctricts, referred to as banners) in Hulunbuir City, Xing'an League, Chifeng City, and Xilin Gol League in Inner Mongolia, and all permanent residents who lived for more than 6 months were selected as the survey subjects. At the same time, the search for Keshan disease cases was carried out in the relevant medical institutions of the 4 leagues (cities) from 2014 to 2018. The "Diagnosis of Keshan Disease" (WS/T 210-2011) and the "Evaluation Methods for Control and Elimination of Key Endemic Diseases" (2019 edition) were used for diagnosis and elimination evaluation of Keshan disease.Results:There were 75 diseased townships under the jurisdiction of the 12 diseased banners in the 4 leagues (cities) in Inner Mongolia, with a permanent resident population of 1 246 900. A total of 356 150 subjects were examined by electrocardiogram, and 86 507 cases were found to be abnormal, with an abnormal rate of 24.29%. A total of 250 patients with chronic Keshan disease were diagnosed by echocardiography or anteroposterior chest X-ray examination, and the prevalence rate was 2.00/10 000; a total of 287 patients with latent Keshan disease were diagnosed, and the prevalence rate was 2.30/10 000; no patients with acute, subacute or new Keshan disease. After case search, 494 suspected Keshan disease cases were screened out, and 6 cases were finally diagnosed as chronic Keshan disease. From 2014 to 2018, there were no new cases of acute or subacute Keshan disease for five consecutive years, and the prevalence rates of chronic Keshan disease and latent Keshan disease were both lower than 5/10 000 in 2019, meeting the national elimination standard for Keshan disease.Conclusion:In 2019, Inner Mongolia has reached the national elimination standard for Keshan disease, but there are still patients with Keshan disease, so it is necessary to continue to strengthen the monitoring of Keshan disease.

Objective:To investigate the carriage status of Neisseria meningitidis ( Nm) among the healthy population in Hebei Province for the prevention and control of meningitis. Methods:From 2015 to 2022, throat swabs were collected from health people, which were selected by cluster random sampling in 11 cities of Hebei.The positive rate of Nm was detected by bacterial culture. The serogroups of isolated strains were identified.The laboratory detection results of Nm strains, combined with epidemiological survey data, were synthetically analyzed. Results:A total of 20 245 people were investigated; 249 strains of Nm were isolated; the overall Nm carriage rate was 1.23%. The carriage rate was significantly higher in men than in women(χ 2=28.831, P<0.05). The positive rates of Nm in different age groups were significantly different(χ 2=428.018, P<0.05), with the highest rates in the 15-19 year-old group(4.90%, 149/3 042). The positive rates of Nm were significantly different in different regions(χ 2=177.512, P<0.05), with the highest positive rate of Nm in Xingtai, Shijiazhuang, Chengde and Baoding city in sequence. Among the isolated Nm strains, ungroupable serogroups, serogroup B, serogroup C, and serogroup W accounted for 71.49%(178/249), 13.65%(34/249), 6.83%(17/249) and 4.42%(11/249), respectively. Conclusions:The carriage rate of Nm among healthy population is generally low in Hebei Province. It is recommended to continue to strengthen monitoring, pay attention to the changes and distribution characteristics of Nm, and formulate scientific and targeted prevention and control measures of meningococcal disease.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with unknown etiology and limited therapeutic options. Activation of fibroblasts is a prominent feature of pulmonary fibrosis. Here we report that lncRNA DACH1 (dachshund homolog 1) is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis. LncDACH1 knockout mice develop spontaneous pulmonary fibrosis, whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation, collagen deposition and differentiation of mouse lung fibroblasts. Similarly, forced expression of LncDACH1 not only prevented bleomycin (BLM)-induced lung fibrosis, but also reversed established lung fibrosis in a BLM model. Mechanistically, LncDACH1 binding to the serine/arginine-rich splicing factor 1 (SRSF1) protein decreases its activity and inhibits the accumulation of Ctnnb1. Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts. Furthermore, loss of LncDACH1 promoted proliferation, differentiation, and extracellular matrix (ECM) deposition in mouse lung fibroblasts, whereas such effects were abolished by silencing of Ctnnb1. In addition, a conserved fragment of LncDACH1 alleviated hyperproliferation, ECM deposition and differentiation of MRC-5 cells driven by TGF-β1. Collectively, LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation, suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis.
