Differential Occupational Health Risks between Methylated PAHs and PAHs: Monitoring 126 PAHs and 6 Oxidative Stress Markers in Paired Serum-Urine Samples.

The hazards of polycyclic aromatic hydrocarbons (PAHs) on occupationally exposed population have been widely acknowledged. However, the occupational exposure risks associated their derivatives, methylated PAHs, remain poorly understood. This study conducted a screen of 126 PAHs and 6 oxidative stress biomarkers (OSBs) in paired serum-urine samples from 110 petrochemical workers to assess the risk associated with different PAHs exposure.

Exposure to per- and polyfluoroalkyl substances in lung cancer patients and their associations with clinical health indicators.

Per- and polyfluoroalkyl substances (PFASs) have potential carcinogenicity, immunotoxicity, and hepatotoxicity. Research has been conducted on PFAS exposure in people to discuss their potential health effects, excluding lung cancer. In this study, we recruited participants (n = 282) with lung cancer from Heilongjiang Province, northeast China.

Screening of pesticides in serum, urine and cerebrospinal fluid collected from an urban population in China.

Human exposure to pesticides is a topic of public health concern for decades. Pesticide exposures have been assessed through the analysis of urine or blood matrices, but little is known on the accumulation of these chemicals in cerebrospinal fluid (CSF). CSF plays an important role in maintaining physical and chemical balance of the brain and central nervous system and any perturbation can have adverse effects on health.

Temporal-spatial variation, source forensics of PAHs and their derivatives in sediment from Songhua River, Northeastern China.

The distribution patterns and health risk assessment of nitrated polycyclic aromatic hydrocarbons (NPAHs), hydroxy polycyclic aromatic hydrocarbons (OH-PAHs), and regular 16 priority polycyclic aromatic hydrocarbons (PAHs) in sediment from the Songhua River in northeastern China were investigated in this research. During dry seasons, concentrations of 16 USEPA priority PAHs, OH-PAHs, and NPAHs were extremely high, with average values of 1220 ± 288, 317 ± 641, 2.54 ± 3.

Occurrence, Removal, and Mass Balance of Polycyclic Aromatic Hydrocarbons and Their Derivatives in Wastewater Treatment Plants in Northeast China.

Polycyclic aromatic hydrocarbons (PAHs), 33 methylated PAHs (Me-PAHs), and 14 nitrated PAHs (NPAHs) were measured in wastewater treatment plants (WWTPs) to study the removal efficiency of these compounds through the WWTPs, as well as their source appointment and potential risk in the effluent. The concentrations of ∑PAHs, ∑Me-PAHs, and ∑NPAHs were 2.01-8.

Fasting Plasma Insulin at 5 Years of Age Predicted Subsequent Weight Increase in Early Childhood over a 5-Year Period-The Da Qing Children Cohort Study.

Background: The association between hyperinsulinemia and obesity is well known. However, it is uncertain especially in childhood obesity, if initial fasting hyperinsulinemia predicts obesity, or obesity leads to hyperinsulinemia through insulin resistance.

Objective: To investigate the predictive effect of fasting plasma insulin on subsequent weight change after a 5-year interval in childhood.

[Meta analysis on acupuncture-moxibustion for amblyopia [correction of agrypnia] ].

The effectiveness and safety of acupuncture-moxibustion for the treatment of agrypnia was systematically reviewed. The clinical randomized controlled trial (RCT) of acupuncture-moxibustion for agrypnia were collected. The literature and document on acupuncture-moxibustion RCT for the treatment of agrypnia that published from January of 2001 to March of 2012 was searched with computer in PubMed, CNKI, Wanfang and VIP database.

The association of a nucleobindin 2 gene (NUCB2) variant with childhood adiposity.

Nucleobindin 2 (NUCB2) is a precursor of nesfatin-1, a hypothalamic anorectic neuropeptide. The association between variants of the NUCB2 gene and adiposity was examined. 142 severely obese Chinese children in Singapore, and 384 normal weight Chinese children from a longitudinal cohort from Da Qing, China, were studied.

Estimation of paracrine signaling using quantitative RT-PCR from multiple patchy lesion samples.

We investigated whether correlations between mRNA levels of cytokines versus other proteins from patchy lesion could estimate cytokine paracrine signaling in vivo. Experiments with rat experimental autoimmune myocarditis (EAM), a patchy myocarditis model, indicated IL-1 and other protein levels were correlated, indicating paracrine signaling pathways in vivo.

Longitudinal study of childhood adiposity and the risk of developing components of metabolic syndrome-the Da Qing children cohort study.

Childhood adiposity is increasingly recognized as a significant predictor of cardiometabolic risks in later life. The aim of this study was to investigate factors associated with longitudinal changes in weight during childhood and the development of metabolic disease risk factors. Four hundred twenty-four children from DaQing city, China, were recruited at 5 y old and followed up for 5 y.

[Compensated hyperinsulinemia based on selective insulin resistance predicts elevation of blood pressure in non-diabetic adults].

Objectives: To investigate if hyperinsulinemia or insulin resistance could predict the elevation of blood pressure in non-diabetic adults.

Methods: One hundred and seventy non-diabetic adults (NGT 107, IGT 63) were included based on the screen by OGTT in 1986. Height, weight, blood pressure were measured.
