RESUMO
Objective To explore the relationship between screen time and prediabetes in adolescents. Methods A cross-section study. A total of 532 adolescents aged 12~18 years in Shandong Zibo Vocational Institute were selected by stratified sampling method. The screen time was investigated by questionnaire survey. Measuring fasting fingertip blood glucose, screening for who with potentially abnormal blood glucose, and measuring their fasting venous blood glucose, which is to determine whether it is prediabetes. Results With the increase of screen time, the risk of prediabetes increased continuously. Compared with adolescents with those who spend 0~119 minute per day screen time, the risk of prediabetes of adolescents with an average daily screen time of 120~239, 240~317,≥318 minute increased by 0.37% , 2.63% , and 3.57% , respectively. After multi-factor adjustment, the risk of prediabetes with who take 240~317,≥318 minute per day screen time is still higher than who with the average daily screen time of 0~119 minute, the adjusted OR was 2.502 (95% CI 1.279-4.897), 2.337 (95% CI=1.189-4.594). Conclusion The results of this study show that the longer the screen time, the higher the risk of prediabetes in adolescents, and adolescents should be encouraged to reduce screen time.

RESUMO
In this paper, using amidoxime as a functional monomer, different generations of polyamidoxime dendrimer magnetic microspheres (Fe3O4@SiO2-g-PAMAM-AO) were fabricated to adsorb Pb2+ and Ni2+ in aqueous solution. The magnetic adsorbents were characterized by FTIR, XRD, SEM, XPS, TEM, EDS, TGA and BET. The effects of different factors (such as solution pH, adsorption time, adsorption temperature, adsorbent dosage etc.) on adsorption were evaluated. Fe3O4@SiO2-g-PAMAM-AO has a maximum Pb(ii) adsorption of 157.25 mg g-1 (100 mg L-1) at pH 5.5. Furthermore, Fe3O4@SiO2-g-PAMAM-AO showed an excellent adsorption performance for the removal of Ni(ii) with a maximum adsorption capacity of 191.78 mg g-1 (100 mg L-1) at pH 8.0. The sorption isotherm data fitted the Freundlich isotherm model well. Adsorption kinetics analysis showed that it was best described by the pseudo-second-order rate model. Desorption experiment results showed that the adsorbent can be reused in the adsorption-desorption cycles.
RESUMO
Objective To study the therapeutic effect of rheum(Chinese herbal medicine) preparation made by using ultrasonic technique on pro-inflammatory cytokines and sepsis in rats.In order to offer novel measure for the treatment of critically ill patients.Methods Firstly, rheum sterile solution was prepared through ultrasonic technique.Secondly, fifty healthy male SD rats were randomly(random number) divided to CLP group and rheum group.Moderate degree of sepsis model was established by using cecal ligation and puncture(CLP).Rats in group rheum received the liquid rheumpreparation via intragastric administration, while rats in group CLP received saline instead.The 7-day survival rate was recorded and was compared between two groups.In addition, another fifty-four rats were randomly(random number) divided to sham group, CLP group and rheum group(n=18 in each group).CLP was performed to induce sepsis in CLP group and rheum group.Then rats in rheum group received rheum sterile solution via intragastric administration, while rats in CLP group received saline instead.At 12 hours, 24 hours and 48 hours after modeling, six rats in each group were randomly sacrificed.Serum TNF-α and HMGB1 levels were detected by ELISA method.Levels of RAGE, HMGB1 and NF-κB P65 in small intestine were detected by Western Blot.Results Level of anthraquinones extracted from rheum by ultrasonic technique was higher than that by conwentional decoction method.The 7-day survival rate of rats in rheum group(76%) was higher than that in CLP group(48%)(P0.05).At 24 hours and 48 hours after modeling, serum HMGB1 levels were significantly lower in rheum group than those in CLP group(P<0.05).Compared with sham group, protein levels of HMGB1, RAGE and NF-κB in small intestine were elevated in CLP group and rheum group at 48 hours after modeling(P<0.01), while protein levels of above biomarker were higher in CLP group than those in rheum group(P<0.05).Conclusions Rheum sterile solution could down-regulate the level of pro-inflammatory cytokines, modulate the inflammatory response, and improve the survival rate in rats with sepsis.
RESUMO
ObjectiveTo investigate the correlation between procalcitonin (PCT), C-reactive protein (CRP) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score, and to investigate the value in assessment of PCT and CRP in prognosis in patients with sepsis.Methods Clinical data of patients admitted to intensive care unit (ICU) of Changzheng Hospital Affiliated to the Second Military Medical University from January 2011 to June 2014 were retrospectively analyzed. 201 sepsis patients who received PCT and CRP tests, and evaluation of APACHEⅡ score and SOFA score were enrolled. The values of PCT, CRP, APACHEⅡ score and SOFA score between survivals (n = 136) and non-survivals (n = 65) were compared. The values of PCT and CRP among groups with different APACHEⅡ scores and SOFA scores were compared. The relationships between PCT, CRP and APACHEⅡ score and SOFA score were analyzed by Spearman correlation analysis. Receiver operating characteristic (ROC) curve was plotted to assess the prognostic value of PCT and CRP for prognosis of patients with sepsis.Results Compared with survival group, the values of PCT [μg/L: 11.03 (19.17) vs. 1.39 (2.61), Z= -4.572,P 20, the value of PCT was 1.45 (2.62), 1.96 (9.04), and 7.41 (28.9)μg/L, respectively, and the value of CRP was 57.50 (83.40), 59.00 (119.70), and 77.60 (120.00) mg/L, respectively. When SOFA score was 0-5, 6-10, and> 10, the value of PCT was respectively 1.43 (3.09), 3.41 (9.75), and 5.43 (29.60)μg/L, and the value of CRP was 49.30 (86.20), 76.00 (108.70), and 75.60 (118.10) mg/L, respectively. There was significant difference in PCT between any two groups with different APACHEⅡ and SOFA scores (P< 0.05 orP<0.01), but no significant differences in CRP were found. The area under the ROC curve (AUC) of PCT for prognosis was significantly greater than that of CRP [0.872 (95% confidence interval 0.811-0.943) vs. 0.512 (95% confidence interval 0.427-0.612),P< 0.001]. When the cut-off value of PCT was 3.36μg/L, the sensitivity was 66.8%, and the specificity was 45.4%. When the cut-off value of CRP was 44.50 mg/L, the sensitivity was 82.2%, and the specificity was 80.3%.Conclusions Compared with CRP, PCT was more significantly correlated with APACHEⅡ score and SOFA score. PCT can be a better indicator for evaluation of degree of severity, and also prognosis in sepsis patients.
