Association between carotid intima-media thickness and visceral fat area in children aged 6-7 years / 中国学校卫生

Objective@#To identify the association of carotid intima-media thickness (cIMT) and visceral fat area (VFA) to inform prevention of cardiovascular disease in later life.@*Methods@#All the grade one students of six non-boarding primary schools in Shunyi District, Beijing were enrolled, based on population-based survey design, to establish the child cohort on sensitization, puberty, obesity and cardiovascular risk (PROC). Socio-demographic information survey and anthropometric measure, blood and urine test were carried out. Robust linear regression was used to determine the relationship between cIMT and other factors.@*Results@#Among 1 711 participants, a significant difference were observed between normal, overweight and obesity children on cIMT [(0.35±0.02)(0.36±0.02)(0.37±0.03)mm] (F=41.4, P<0.01) and VFA [16.2(13.6-19.3), 22.7(18.6-27.3), 51.5(33.9-73.0)cm2] (χ2=854.5, P<0.01). After adjusting age and sex, univariate robust linear regression showed that cIMT was associated with height, SBP, DBP, HDL-C, VFA (P<0.05) and TG (P=0.055). Multivariable robust linear regression indicated that in total and boys only included models, cIMT was associated with VFA and SBP(β=0.000 2, 0.000 2, 0.000 2, 0.000 2, P<0.05); while in girls only included model cIMT was associated with VFA and TG (β=0.000 2, 0.006 2, P<0.05).@*Conclusion@#VFA is stable to predict the increase of cIMT in children. We can use VFA to simplify the classification management of children and inform targeted early prevention of cardiovascular disease in adulthood.

Low-dose chidamide restores immune tolerance in ITP in mice and humans.

Increased macrophage phagocytosis of antibody-coated platelets, as well as decreased numbers and/or impaired function of CD4+CD25+Foxp3+ regulatory T (Treg) cells, has been shown to participate in the pathogenesis of immune thrombocytopenia (ITP). Low-dose histone deacetylase inhibitors (HDACi's) are anti-inflammatory and immunomodulatory agents that can enhance immunosuppression in graft-versus-host disease by increasing the number and function of Foxp3+ Treg cells, but it is unclear whether they have the potential to promote immune tolerance and platelet release in ITP. In this study, we performed in vitro and in vivo experiments and found that a low-dose HDACi (chidamide) alleviated thrombocytopenia in passive and active murine models of ITP. Further, low-dose HDACi's attenuated macrophage phagocytosis of antibody-coated platelets, stimulated the production of natural Foxp3+ Treg cells, promoted the peripheral conversion of T cells into Treg cells, and restored Treg cell suppression in vivo and in vitro. Finally, we confirmed that low-dose HDACi's could regulate CTLA4 expression in peripheral blood mononuclear cells through modulation of histone H3K27 acetylation. Low-dose HDACi treatment in ITP could be offset by blocking the effect of CTLA4. Therefore, we propose that low-dose chidamide administration has potential as a novel treatment for ITP in the clinic.

Specialized adaptations for springtail predation in Mesozoic beetles.

Insects exhibit a variety of morphological specializations specific to particular behaviors, and these permit the reconstruction of palaeobiological traits. Despite the critical importance of predator-prey strategies in insect evolution, the appearance of particular aspects of predation are often difficult to determine from the fossil record of hexapods. Here we report the discovery of highly specialized, mid-Cretaceous ant-like stone beetles (Staphylinidae: Scydmaeninae) displaying morphological modifications unknown among living scydmaenids and associated with predation on springtails (Collembola), a widespread and abundant group of significantly greater geological age. Cascomastigus monstrabilis gen. et sp. nov. exhibits an extremely large body size, elongate clubbed maxillary palpi, toothed mandibles, and more importantly, slender and highly modified antennae that functioned as an antennal setal trap. Such an antennal modification is analogous to that of the modern ground beetle genus Loricera (Carabidae: Loricerinae), a group possessing a specialized antennal setal trap exclusively for the capture of springtails. The presence of an identical antennal setal trap in C. monstrabilis demonstrates a unique and dramatic form of obligate predation among the late Mesozoic insects.

New data on brachypterous Paederus (Coleoptera, Staphylinidae) of mainland China.

A key to the brachypterous Paederus species of mainland China is provided.

Three new species of Nazeris Fauvel in Xizang, China (Coleoptera, Staphylinidae, Paederinae).

The paederine genus Nazeris Fauvel, 1873 previously included 241 described species and seven subspecies (Assing, 2016). As many as 49 species have been recorded from the Himalaya (Assing, 2014). In China, Yunnan has the greatest diversity of Nazeris (45 species). Xizang is the second largest province of China, and adjacent to Yunnan and the Himalaya. But only two Nazeris species have been described from this area: N. motuensis Hu, Li & Zhao, 2008 and N. tangi Hu, Li & Zhao, 2008. Both of them were found in eastern Xizang. Three additional species in the insect collection of the Shanghai Normal University are described in this paper.
