ABSTRACT

Objective@#To investigate the prevalence of metabolic syndrome (MS) and to explore the relationship of MS with screen time (ST) among children aged 6-13 years in Guangzhou, China.@*Methods@#A total of 4 523 children aged 6-13 from 5 primary schools in Guangzhou were selected using stratified random cluster sampling method. Questionnaire was used to assess children’s basic demographic characteristics and ST. Children’s height, weight, waist circumference and blood pressure were measured objectively, and their blood glucose, triglyceride and high-density lipoprotein-cholesterol were tested. -Chi-square test was performed to compare the prevalence of MS in children among different ST levels. Logistic regression model was used to explore the association between ST and MS.@*Results@#The prevalence of MS in children was 2.4%, and that among boys (3.0%) was higher than in girls (1.7%, P=0.01). children were classified into three groups according to duration of ST: low ST (less than 1 h), moderate ST (1-2 h), high ST (higher than 2 h, 9.0% of total participants). Prevalence of central obesity, triacylglycerol and MS in high ST group was significantly higher than children with low ST(P<0.05). Children with high level of ST showed higher risks of central obesity (OR=1.43, 95%CI=1.04-1.96) and MS (OR=1.94, 95%CI=1.11-3.40) compared with low-level ST group.@*Conclusion@#Higher level of screen time associates with an increased risk of MS in children, which suggest the importance of effective early intervention.

ABSTRACT

Objective Cell cycle-associated protein 1 (Caprin-1) is closely related to the development and progression of cancer. This study aimed to explore the expression of Caprin-1 in the clinical glioma specimen and its influence on the biological char-acteristics of the glioma cell line. Methods Brain tissue specimens were collected from 29 glioma patients and 2 normal humans that died of accidental trauma. A stably transfected U251 cell line with overex-pressed Caprin-1 was established,and the U251 cells were transfected with the pEGFP-C1 plasmid (the negative control group), or the pEGFP-C1-Caprin-1 plasmid (the experimental group), or left un-transfected (the blank control group). The expressions of Caprin-1 mRNA and protein in the cells were determined by RT-PCR and Western blot, and the proliferation and migration of the cells exam-ined by scratch test and Transwell assay,respectively. Results The expression of Caprin-1 was upregulated with the increased grade of glioma,145.9±22.0,444.4±110.0,and 1661.0±54.5 in WHO gradeⅡ,Ⅲ,andⅣglioma,respectively,significantly higher than in the normal brain tissue (P<0.05). Both the mRNA and protein expressions of Caprin-1 were remarkably higher in the experimental group (1.70±0.19 and 1.07±0.09) than in the blank control(0.89±0.10 and 0.52±0.04) and negative control(0.98±0.08 and 0.58± 0.03) (P<0.05).The A value was also markedly higher in the former group(2.55±0.14) than in the latter two(1.40±0.06 and 1.35± 0.04) (P<0.01),and so were the count of migrated cells(526.00±42.19 vs 289.00±29.24 and 279.00±32.48,P<0.01) and the ex-pression of CyclinD1 (0.60±0.05 vs 0.13±0.03 and 0.15±0.05, P<0.01). Conclusion The expression of Caprin-1 in the U251 cells was upregulated with the increased WHO grade of glioma,and the overexpression of Caprin-1 accelerated the proliferation and mi-gration of the U251 cells.

ABSTRACT

<p><b>BACKGROUND</b>The clinical significance of metabolic syndrome (MS) score, MS, and its individual components with respect to risk prediction of coronary artery disease (CAD) remains unclear. The objective of this study was to investigate whether and to what extent MS score, MS, and its individual components were related to the risk of CAD.</p><p><b>METHODS</b>Among 1191 participants who underwent coronary angiography for the confirmation of suspected myocardial ischemia, 858 were included in this study according to the inclusion criteria from September 2010 to June 2013. MS was diagnosed with the 2005 National Cholesterol Education Program Adult Treatment Panel III criteria. The severity of coronary atherosclerosis was assessed by Gensini score.</p><p><b>RESULTS</b>The results showed that the age- and sex-adjusted odds ratios (OR s) for CAD were as follows: MS score, 1.327; MS, 2.013; elevated waist circumference, 1.447; reduced high-density lipoprotein cholesterol, 1.654; and elevated fasting glucose, 1.782; all P < 0.05; whereas for elevated triglycerides, 1.324, and elevated blood pressure, 1.342, both P > 0.05. After multivariate adjustment, results showed that only MS and elevated fasting glucose were significantly associated with CAD (OR, 1.628, 95% confidence interval [CI], 1.151-2.305, P = 0.006 for elevated fasting glucose, and OR, 1.631, 95% CI, 1.208-2.203, P = 0.001 for MS). The study showed that only MS score and elevated fasting glucose were significantly associated with Gensini score (standardized coefficient, 0.101, P = 0.031 for elevated fasting glucose and standardized coefficient, 0.103, P = 0.009 for MS score).</p><p><b>CONCLUSIONS</b>The present study demonstrated that MS score, MS, and its individual components might have different contributions to CAD prevalence and severity. MS and elevated fasting glucose were independent risk factors for the prevalence of angiographic CAD whereas MS score and elevated fasting glucose were significantly associated with the severity of CAD.</p>

ABSTRACT

<p><b>BACKGROUND</b>Serum high sensitive C-reactive protein (hs-CRP), adiponectin levels and urine albumin excretion rate (UAER) are probably associated with inflammation and atherosclerosis. The aim of this study was to determine the three markers in coronary artery disease (CAD) subjects with different glucose tolerance status in a Chinese population and further explore the levels of the three markers in these subjects and the possible association of these markers with CAD risk factors and the severity of CAD as well.</p><p><b>METHODS</b>A total of 242 subjects with angiographically documented CAD were recruited, and then assigned to three groups: the normal glucose tolerance (NGT) + CAD group, including 100 CAD patients with NGT; the impaired glucose tolerance (IGT) + CAD group, 40 CAD patients with IGT; the type 2 diabetes mellitus (T2DM) + CAD group, 102 CAD patients with T2DM. Serum hs-CRP, adiponectin levels as well as UAER were measured in all subjects.</p><p><b>RESULTS</b>Serum hs-CRP levels were increased in the T2DM + CAD group compared with the NGT + CAD group (4.71 +/- 2.59) vs (3.60 +/- 2.46) mg/L, P = 0.037. Serum adiponectin levels were gradually decreased from the NGT + CAD to IGT + CAD to T2DM + CAD groups, (5.99 +/- 1.84), (5.82 +/- 1.72) and (4.65 +/- 1.71) mg/L, P = 0.002 and 0.040 for NGT + CAD and IGT + CAD groups vs T2DM + CAD group, respectively. While the UAER was gradually increased from the NGT + CAD to IGT + CAD to T2DM + CAD groups, (6.42 +/- 2.51), (6.89 +/- 2.94) and (15.03 +/- 4.22) microg/min (P < 0.001) for NGT + CAD and IGT + CAD groups vs T2DM + CAD group. Multiple linear stepwise regression analysis showed that waist-hip ratio (WHR) and low density lipoprotein cholesterol (LDL-C) were the significant determinants of serum hs-CRP levels; triglyceride (TG), high density lipoprotein cholesterol (HDL-C), age, WHR, T2DM, 2-hour serum insulin (2hINS), sex, and apolipoprotein B were the significant determinants of serum adiponectin levels; and systolic blood pressure (SBP), T2DM, and hemoglobin A1c (HbA1c) were the significant determinants of UAER in all subjects (R(2) = 0.070, 0.352, and 0.214, respectively). However, no significant correlation was seen for hs-CRP, adiponectin and UAER with the severity of CAD. Hs-CRP levels were significantly correlated with UAER.</p><p><b>CONCLUSIONS</b>There was a trend of increased serum hs-CRP levels from the NGT + CAD to IGT + CAD to T2DM + CAD groups, though it only showed significance in the T2DM + CAD group compared with the NGT + CAD group. Serum adiponectin levels were decreased and UAER was increased from the NGT + CAD to IGT + CAD to T2DM + CAD groups. Increased UAER and serum hs-CRP, and decreased adiponectin levels were associated with traditional CAD risk factors but failed to be correlated with the severity of CAD. Hs-CRP levels were significantly correlated with UAER.</p>

ABSTRACT

A catalytic kinetic photometric method for the determination of nitrite with surfactant sensitizer has been developed. The method is based on the catalysis of NO2- to the discoloring reaction of pyronine B oxidized by potassium bromate in the solution of dilute H3PO4. When cetylpyridine bromide was used as a sensitizer of the reaction, the sensitivity increased by 2.5 times approximately. There was linear relationshop of lg(Ao/A) with nitrite in the range 0.005 ~ 0.15 mg/L. The detection limit was 0.004 mg/L. The method was used in the determination of trace nitrite in water and vegetable samples with satisfactory results.
