Background Body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) have long been important physical assessment indicators. In recent years a body shape (ABSI) roundness (BRI) gained importance as new However, it is unclear how these indicators assess psychological symptoms in adolescents. The main purpose of this study was to determine the ability BMI, WC, WHtR, ABSI, BRI recognize Chinese adolescents examine whether ABSI are superior traditional WHtR. Methods...

Acute lung injury (ALI) is a common complication following intestinal ischemia/reperfusion (I/R) and major contributing factor to its high mortality rate. Sirtuin 1 (SIRT1), NAD+‑dependent deacetylase, has been reported have an important role in apoptosis inhibition, oxidative stress resistance cell lifespan extension through deacetylation of forkhead box protein O3 (FOXO3). It demonstrated that icariin (ICA), flavonoid extracted from Epimedium, upregulates SIRT1 expression. The aim the...

The consisted HEL, which was conjugated with either fluorescein isothiocyanate (FITC) or lucifer yellow...

Nogo-B is an endoplasmic reticulum-residential protein with distinctive functions in different diseases. However, it remains unclear the role of liver sterile inflammatory injury. This study aims to elucidate and mechanisms ischemia reperfusion injury (IRI). The expression function were analyzed biopsy/serum specimens from 36 patients undergoing ischemia-related hepatectomy a mouse model IRI. Human harvested prior post-reperfusion. knockout (Nogo-BKO) myeloid-specific (Nogo-BMKO) mice used...

Abstract Background Mental disorders among adolescents have become a worldwide public health problem. This study aimed to estimate the best combination of exercise time and screen promote mental Chinese adolescents. Methods Participants included 7200 aged 13–18 years from six regions China. Screen data were collected via self-rated questionnaire. Psychological symptoms (e.g., often feeling depressed, school-weary) evaluated with “Multidimensional Sub-health Questionnaire Adolescents”....

Picky eating behaviours are common in young children and may adversely affect dietary intake. This study examined the adequacy of patterns nutrient intake preschool-aged China Hong Kong with picky weight-for-height lowest quartile WHO Growth Standards.Dietary was assessed using baseline 3-day food records from a multicenter, randomized trial Chinese (N=151) ages 2.5-5 years characterized as eaters by their parents <=25th percentile Standards. Nutrient intakes were calculated validated...

Objective To assess the association between body mass index (BMI) and physical fitness (PFI) among children adolescents in Xinjiang Uyghur Autonomous Region, China. Methods In total, 17,618 aged 7–18 years from selected region were enrolled this cross-sectional study (8,800 boys 8,818 girls). Participants stratified by age sex divided into five groups BMI percentiles: very low (BMI <5th percentile); low, (5th ≤ < 15th normal (15th 85th high (85th 95th ≥95th percentile). PFI was assessed...

We assessed trends in physical fitness by age group and nutrition status among children adolescents Xinjiang during 1985-2014. The data of 49,357 participants aged 7-18 were extracted 1985, 1995, 2005, 2014. Growth nutritional defined using World Health Organization definitions. A indicator (PFI) was calculated as the sum six components measured every survey. relationship between body mass index (BMI) PFI investigated nonlinear regression. Taking 1985 a reference, increased to 2 1995 then...

To estimate the association between sugar-sweetened beverage (SSB) consumption and executive function (EF) among Chinese Tibetan adolescents.

Carnosic acid (CA), found in rosemary, has been reported to have antioxidant and antiadipogenic properties. Here, we investigate the molecular mechanism by which CA inhibits hydrogen peroxide (H 2 O )-induced injury HepG2 cells. Cells were pretreated with 2.5–10 μmol/L for h then exposed 3 mmol/L H an additional 4 h. dose-dependently increased cell viability decreased lactate dehydrogenase activities. Pretreatment completely attenuated inhibited expression of manganese superoxide dismutase...

This study aimed to explore the impact of environmental factors such as latitude, altitude, family socioeconomic status (SES), and level urbanization on overweight obesity (ow/ob) in children adolescents. The participants comprised 26,120 adolescents aged 10-18 from 16 provinces China. Differences prevalence ow/ob under different conditions were evaluated by chi-square test. influence various was obtained logistic regression analysis.
