Development of web-based diabetic patient management system using short message service (SMS)

We developed a blood glucose management system using the Internet and short message service (SMS) which can lessen the social economic burden and materialize an individualized diabetes mellitus management. A total of 185 diabetic patients participated in this study and their mean age was 42.4 years old (8-79 year-old). Participants sent their self-measured blood glucose levels, medication and its dosages, amount of meal, and degree of exercise to their health providers in this specialized web-based diabetes management system for 3 months. The health providers consisting of endocrinology specialists, dietitians, and nurses sent recommendations for individualized diabetes management according to the data on the web. Laboratory tests including lipid profiles and glycated hemoglobin (HbA1c), and a survey of satisfaction about this system were performed before and after the study period. The mean HbA1c improved from 7.5 +/- 1.5 to 7.0 +/- 1.1% after using the management program (P = 0.003). The mean serum triglyceride and HDL-cholesterol levels turned for the better also. HbA1c improved from 8.4 +/- 1.2 to 7.5 +/- 1.0% after applying this program to patients with the HbA1c of 7% or higher at baseline (P = 0.010). We propose this web-based diabetic patient management system as a new tool for communication between health care providers and patients.     

家兔对小鼠抗血吸虫靶抗原单克隆抗体的抗抗体应答

本文报告从分泌具血吸虫保护性IgG_(2a)表型1E2McAb的杂交瘤培养上清液中,应用蛋白A-葡聚糖柱层析法纯化的McAb免疫家兔,采用纯化McAb分别进行Dot-ELISA、免疫双扩散和免疫印迹试验、ELISA观察免疫血清中抗McAb和抗-抗McAb的产生及其动态变化规律。主要结果表明:(1)1E2McAb免疫后,20d开始出现抗McAb,若不加强免疫,抗McAb逐渐减弱:若加强免疫,则抗McAb水平较高,且持续30-50d。(2)免疫血清中的抗-抗McAb,能起抗-抗Id的作用,可识别不同的血吸虫抗原及血吸虫抗原中不同抗原决定簇(90,68和45kD_a),而且免疫后不同时期抗-抗McAb识别不同抗原的水平不同(滴度1:100-1:1600)。对抗血吸虫肥抗原McAb免疫后抗抗体应答的观察,可为研制不同抗独特型McAb创造条件。

Preparation and characterization of chitosan membranes

The present study investigates a new solvent system for the dissolution of chitosan and a new method for preparing chitosan membranes. First, aqueous tartaric acid was used to pretreat chitosan. Then, the chitosan was precipitated with ethanol or other regenerating agents, and 1.5 mL of 1-ethyl-3-methylimidazolium acetate ([EMIM]AC) was added to obtain translucent suspensions. The chitosan membranes were prepared by casting the suspensions on glass plates and allowing solvent evaporation. The structure and properties of the films were investigated by SEM, FT-IR, XRD and TGA. Also, the mechanical properties, as well as physical and chemical characteristics, of the chitosan films were evaluated. The results indicated that the optimum dissolution time was 10 min and the most suitable drying temperature was 60 °C. The thus-prepared film was moderately thick (about 0.02 mm) and had a smooth surface, without curling. The chitosan film prepared by ethanol regeneration had a tensile strength of up to 24 MPa, a minimum swelling degree of 78%, and a water vapor transmission rate of 270 g m⁻² d⁻¹ without the addition of plasticizer.

Nutritional and nutraceutical characteristics of Sageretia theezans fruit

The fruit of Sageretia theezans is one of many underutilized edible fruits that grow along the southern seashores of East Asia. In this study, to evaluate the nutritional and nutraceutical values of S. theezans fruit, the composition of minerals, organic acids, and proximate and fatty acids, the total phenolic, total flavonoid, and total anthocyanin content, and the antioxidant and antidiabetic activities of S. theezans fruit were analyzed. The results indicate that S. theezans fruit could be classified as a potential potassium-, malic acid-, and linoleic/oleic acid-rich fruit. In addition, The ethyl acetate (EtOAc) fraction of the 70% ethanol (EtOH) crude extract exhibited strong antioxidant activities including free radical scavenging and reducing power activities compared with the same concentration of butylated hydroxytoluene. Furthermore, the EtOAc fraction showed significant inhibition of α-glucosidase activity. The analysis of the total phenolic and flavonoid content suggested that the remarkable antioxidant and antidiabetic activities of the EtOAc fraction are due to the presence of high levels of polyphenolic compounds.     

Efficacy and safety of tumor necrosis factor-α blockers for ulcerative colitis: A systematic review and meta-analysis of published randomized controlled trials

To evaluate the efficacy and safety of TNF-α blockers for ulcerative colitis. A systematic search for randomized controlled trials (RCTs) of TNF-α blockers for treatment of ulcerative colitis (UC) were performed in PubMed, Web of Science, Embase and cochrane clinical trial. We estimated Pooled estimates of the odds ratio (OR) and relevant 95% confidence interval (CI) using fixed effects model or random effects model as appropriate. Heterogeneity, publication bias, and subgroup analyses were conducted. Nine randomized controlled studies met the selection criteria with a total of 2518 patients. Five studies compared Infliximab with placebo. Two studies compared Infliximab to corticosteroids. Two studies compared Adalimumab to placebo. One study compared subcutaneous golimumab to placebo. Short-term response, short-term remission, long-term remission and mucosal healing were better in the TNF-α blocker group than in the control group (p < 0.05). TNF-α blockers decreased the colectomy rate and serious adverse reactions (p < 0.05). The TNF-α blockers were superior to controls in achieving short-term clinical response/remission, long-term remission and mucosal healing and decreased the colectomy rate and serious adverse reactions.     

Interaction of gallic acid with trypsin analyzed by spectroscopy

The interactions between trypsin and gallic acid (GA) were investigated by means of fluorescence spectroscopy, UV-vis absorption spectroscopy, resonance light scattering (RLS) spectroscopy, synchronous fluorescence spectroscopy, and enzymatic inhibition assay. It was found that GA can cause the fluorescence quenching of trypsin during the process of formation of GA-trypsin complex, resulting in inhibition of trypsin activity (IC₅₀ = 3.9 × 10⁻⁶ mol/L). The fluorescence spectroscopic data showed that the quenching efficiency can reach about 80%. The binding constants were 1.9371 × 10⁴ L/mol, 1.8192 × 10⁴ L/mol, and 1.7465 × 10⁴ L/mol at three temperatures, respectively. The thermodynamic parameters revealed that hydrogen bonds, van der Waals, hydrophobic, and electrostatic interactions were involved in the binding process of GA to trypsin. Molecular modeling studies illustrated a specific display of binding information and explained most of the experiment phenomena. The microenvironments of tryptophan and tyrosine residue in trypsin were changed by the GA. Results indicated that GA was a strong quencher and inhibitor of trypsin.     

Analysis of clinical prognosis in patients with non-hepatic hyperammonemia

The aim of this study was to evaluate the association of non-hepatic hyperammonemia (NHH) with the prognosis of critically ill patients with NHH.According to the serum ammonia level, the patients with NHH (n = 498) were retrieved by us. The risk factors of the mortality with NHH patients were investigated by conducting univariate and multivariate logistic regression analyses. A nomogram to predict the risk of hospital mortality was constructed. Receiver operating characteristic curve (ROC) analysis was conducted to compare nomogram (ammonia into a prognostic model, P1) with the simplified acute physiology II (SAPSII) and quick sequential organ failure assessment (qSOFA).Five independent factors for the mortality in patients with NHH were identified, including age, platelets, bun, hemoglobin, and ammonia. Models P1 using ammonia showed good prediction power. The AUROC of P1 (AUROC, 0.755 [95% CI, 0.713–0.796]) was higher than that of qSOFA (AUROC, 0.500 [95% CI, 0.449–0.551]), and SAPS II (AUROC, 0.703[95% CI, 0.658–0.748]).Ammonia was an independent prognostic predictor of mortality for NHH patients. We developed a nomogram that can predict hospital mortality with patients. Nomogram had superior discriminative power to qSOFA and SAPS II, indicating that the nomogram may have clinical utility.
