Basal Energy Expenditure of Chinese Healthy Adults: Comparison of Measured and Predicted Values.

Objective: This study aimed to measure the basal energy expenditure (BEE) of Chinese healthy adults and establish an accurate predictive equation for this population.

Methods: In total, 470 Chinese healthy adults had their BEE measured using the Cosmed K4b portable metabolic system. Multiple linear regression analysis was applied to develop new optimal equations for predicting BEE.

Extract of Thunb. enhances the inhibitory effect of 5-fluorouracil on gastric cancer cells through the AKT-mTOR pathway.

Background: Gastric cancer is one of the most common and deadly malignancies worldwide. Despite recent medical progress, the 5-year survival rate of gastric cancer is still unsatisfactory. 5-fluorouracil (5-Fu) is one of the first-line antineoplastic treatments for gastric cancer, as it can effectively induce cancer cell apoptosis.

Habitual dietary calcium intakes and calcium metabolism in healthy adults Chinese: a systematic review and meta-analysis.

To investigate the metabolic differences of calcium requirements between Chinese and Westerners, we examined systematically the characteristics of calcium metabolism in Chinese adults with habitual dietary calcium intakes. We searched PubMed, Cochrane Library, SinoMed, and National Index to Chinese Newspapers & Periodicals, from inception to March 17, 2015, as well as the bibliographies of any relevant papers and journals, for trials assessing calcium metabolism in healthy Chinese adults within 18-60 years of age on the typical Chinese diet. We extracted a standardized dataset from metabolic studies that reported intake, retention, urinary excretion, faecal excretion and/or fractional absorption of calcium.

miR-630 functions as a tumor oncogene in renal cell carcinoma.

Introduction: MicroRNAs (miRNAs) are non-coding RNAs that regulate multiple cell processes during cancer progression. Renal cell carcinoma (RCC) is a malignancy with a poor prognosis. In this study, we aimed to investigate the roles of miR-630 in RCC progression.

Up-regulation of miR-630 in clear cell renal cell carcinoma is associated with lower overall survival.

Introduction: MicroRNAs (miRNAs) are noncoding RNAs that regulate multiple cellular processes during cancer progression. MiR-630 has recently been identified to be involved in tumorigenesis of several cancers such as lung cancer and gastric cancer. However, the regulation of miR-630 in clear cell renal cell carcinoma (ccRCC) has not yet been reported before.

Visceral fat area, waist circumference and metabolic risk factors in abdominally obese Chinese adults.

Objective: To examine the association of visceral adiposity as measured by VFA and WC with lipid and glucose metabolic biomarkers in abdominally obese Chinese adults, and to assess whether WC could be an indicator of visceral fat.

Methods: WC and VFA were measured in 155 overweight and obese adults. A fasting blood sample was collected from participant (n = 118) whose VFA > or = 100 cm2 for analyses of lipid and glucose profile.

The use of copper(II) isonicotinate-based micro-solid-phase extraction for the analysis of polybrominated diphenyl ethers in soils.

A micro-solid-phase extraction (μ-SPE) device was developed by filling copper(II) isonicotinate coordination polymer (Cu(4-C(5)H(4)N-COO)(2)(H(2)O)(4)) into a porous polypropylene envelope, and the μ-SPE, coupling with gas chromatography (GC) with a micro-cell electron capture detector (μ-ECD), was used for extraction and determination of PBDEs in soils. Variables affecting extraction procedures, including temperature, water volume, extraction time, and desorption time, were investigated in a spiked soil, and the parameters were optimized. Under the optimal experimental conditions, the method detection limits for seven PBDEs (BDE-28, 47, 99, 100, 153, 154, and 183) were in the range of 0.

Television news coverage of obesity in China, 1982-2009.

Objective: The purpose of this study was to explore how obesity was covered in television news in China, including the trends over time and the characteristics of obesity-related news.

Methods: The frame analysis was adopted to assess the content of obesity-related news broadcasted in China Central Television (CCTV) from 1982 to 2009. To investigate the characteristics of the news, the obesity-related news was divided into subgroups according to populations concerned, as well as the period in which the news was broadcasted.

Postprandial glycaemic and insulinaemic responses to GM-resistant starch-enriched rice and the production of fermentation-related H2 in healthy Chinese adults.

Consumption of resistant starch (RS)-enriched foods is associated with decrease in the postprandial glycaemic and insulinaemic responses, accompanied by the production of fermentation-related gases in the large bowel. The present study aimed to determine the postprandial glycaemic and insulinaemic responses to the GM RS-enriched rice and the fermentation-related production of H2 in young and healthy Chinese adults. A total of sixteen young adults (nine men and seven women) were recruited and divided into three groups.

[Association of genetic polymorphisms in selenoprotein GPX1 and TXNRD2 with genetic susceptibility of gastric cancer].

Objective: This study examined whether the two polymorphisms of GPX1 (198Pro--> Leu) and TXNRD2 (370Lys-->Arg) contributed alone or in combination, to the risk of gastric cancer development.

Methods: A total of 361 patients with gastric cancer and 363 cancer-free controls were recruited and their genotypes of the two polymorphisms were determined by polymerase chain reaction-based restrictive fragment length polymorphism (PCR-RFLP) method. Odds ratio (OR) and 95% confidence interval (CI) were computed using unconditional logistic regression model.

Visceral fat, arterial stiffness, and endothelial function in peritoneal dialysis patients.

Background: The relationship between overweight or obesity and mortality in peritoneal dialysis (PD) patients remains controversial. Both pulse-wave velocity (PWV) and endothelial dysfunction are related to an increased risk of cardiovascular disease. However, the association between PWV, endothelial dysfunction, and visceral adipose tissue in PD patients is not well-understood.

[Pilot study on total energy expenditure by accelerometer and physical activity logs].

Objective: Using accelerometer and physical activity logs to evaluate daily energy expenditure, as to providing a simple and convenient method to survey the total energy expenditure (TEE).

Methods: The different activity intensities recorded by accelerometer were distinguished into a certain different energy expenditure value by gas metabolism method. Forty-one participants wore the accelerometer for 7 days continuously and completed physical activity logs everyday at the same time.

[Study on the reliability and validity of international physical activity questionnaire (Chinese Vision, IPAQ)].

Objective: To study the reliability and validity of Chinese version of International Physical Activity Questionnaire (IPAQ) and to provide an instrument for physical activity measurement in Chinese-spoken population.

Methods: Test-retest reliability was systemically assessed in 94 participants sampled from college students. Questionnaires were completed twice with a three-day interval.
