BACKGROUND The global rise in the prevalence of type 2 diabetes mellitus(T2DM)in children and adolescents is partly linked to the increasing rates of childhood obesity and physical inactivity.AIM To explore the independent relationships of visceral adiposity index(VAI)and cardiorespiratory fitness(CRF)with fasting plasma glucose(FPG)in adolescents.METHODS This descriptive cross-sectional study included 403 adolescents(202 boys and 201 girls)aged 11-19 years.Participants were evaluated for VAI,CRF,and FPG.Regression models,adjusted for age and maturity status,were used to assess the associations between VAI,CRF,and FPG.RESULTS The prevalence of T2DM risk was 15.3%(girls=7.4%;boys=7.9%).In boys,high VAI was positively associated with FPG(β=0.190,P=0.009),while low CRF was negatively associated with FPG(β=-0.206,P=0.010).These associations persisted even after adjusting for CRF and VAI.However,no significant associations between VAI,CRF,and FPG were observed in girls(P>0.05).Adolescents with high VAI and low fitness levels demonstrated poorer glycemic profiles.CONCLUSION Among boys,both VAI and CRF were independently associated with T2DM risk,with CRF showing a stronger association.These associations were not observed in girls.Promoting regular aerobic exercise and healthy diets may serve as essential public health promotion strategies in preventing and managing T2DM risk in adolescents. 展开更多

Objective Waist circumference, waist-to-hip ratio and waist-to-height ratio, which are the indicators or measures of abdominal adiposity, have long been hypothesized to increase the risk of stroke; yet evidence accumulated till date is not conclusive. Here, we conducted a dose-response meta-analysis to summarize evidences of the association between these measures of abdominal adiposity and the risk of stroke. Methods PubMed and Web of Science databases were searched from inception to May 2015. Two investigators independently conducted the study selection and data extraction. Dose-response relationships were assessed by the generalized least squares trend estimation, while the summary effect estimates were evaluated by the use of fixed- or random-effect models. Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity and the robustness of the pooled estimation. Publication bias of the literature was evaluated using Begg's and Egger's test. Results Altogether 15 prospective cohort studies were identified in this study. The summary of relative risks (95% confidence intervals) of stroke for the highest versus the lowest categories was 1.28 (1.18-1.40) for waist circumference, 1.32 (1.21-1.44) for waist-to-hip ratio, and 1.49 (1.24-1.78) for waist-to-height ratio. For a 10-cm increase in waist circumference, the relative risk of stroke increased by 10%; for a 0.1-unit increase in waist-to-hip ratio, the relative risk increased by 16%; and for a 0.05-unit increase in waist-to-height ratio, the relative risk increased by 13%. There was evidence of a nonlinear association between waist-to-hip ratio and stroke risk, Pnonlinearity=0.028, Conclusion Findings from our meta-analysis indicated that waist circumference, waist-to-hip ratio, and waist-to-height ratio were positively associated with the risk of stroke, particularly ischemic stroke. 展开更多

Background: Adipose-derived stem cells (ASCs) are considered ideal candidates for both research and cellular therapydue to ease of access, large yield, feasibility, and efficacy in preclinical and clinical studies. Unlike the subcutaneousabdominal fat depot, breast ASCs features are still not well recognized, limiting their possible therapeutic use. ASCswere found to exert immunomodulatory and antioxidative activities for maintaining homeostasis and functionality ofdiseased/damaged tissues. This study aims to investigate the immunomodulatory and antioxidative potentials of breastversus abdominal isolated ASCs to find out which anatomical site provides ASCs with better immunoregulatory andoxidative stress resistance capabilities.Methods: ASCs were isolated from abdominal and breast tissues. Gene expression analysis was conducted for a panelof immunomodulatory and antioxidative genes, as well as adipokines and proliferation genes. Flow cytometric analysisof a group of immunomodulatory surface proteins was also performed. Finally, the significantly expressed genes haveundergone protein-protein interaction and functional enrichment in silico analyses.Results: Our results revealed similar morphological and phenotypic characteristics for both breast and abdominalASCs. However, a significant elevation in the expression of two potent immunosuppressive genes, IL-10 and IDO aswell as the expression of the multifaceted immunomodulatory adipokine, visfatin, was detected in breast versusabdominal ASCs. Moreover, a significant overexpression of the antioxidative genes, GPX1, SIRT5, and STAT3 and theproliferation marker, Ki67, was also observed in breast ASCs relative to abdominal ones. In silico analysis showed thatboth of the differentially upregulated immunomodulatory and antioxidative mediators integratively involved inmultiple biological processes and pathways indicating their functional association.Conclusion: Breast ASCs possess superior immunomodulatory and antioxidative capabilities over abdominal ASCs. Ourfindings shed light on the possible therapeutic applications of breast ASCs in immune-related and oxidative stressassociateddiseases. 展开更多

The present study is conducted to determinate fatty acids(FA) composition in 3 adipose tissues. Subcutaneous and perirenal adipose tissues were prepared from 24 Ningxiang castrated boars and 24 castrated gilts fattened by a traditional diet for 56 d, respectively. The results showed that the FA profile in the 3 adipose tissues(dorsal subcutaneous adipose [DSA], abdominal subcutaneous adipose [ASA], and perirenal adipose [PA]) differed greatly. In boars, the proportions of oleic acid(c18:1 n9 c)(P < 0.05), cis-11-20 c acid(c20:1)(P < 0.05), and a-linolenic acid(c18:3 n3)(P < 0.05) in DSA were the highest among 3 adipose tissues, whereas palmitic acid(c16:0)(P < 0.05) and stearic acid(c18:0)(P < 0.05) in DSA had the lowest proportion. In gilts, cis-11-20 c acid(c20:1)(P < 0.05) in DSA was the highest, while stearic acid(c18:0)(P < 0.05) in subcutaneous adipose was the lowest among these deposits. Overall, the results indicate that from external to inner carcass of boars, the sum of saturated fatty acids(SFA) increase, but the sum of monounsaturated fatty acids(MUFA) decrease, while ASA of gilts have the greatest proportion of MUFA and the lowest SFA. Sex and adipose locations as significant effects on the FA profile are interaction. 展开更多
