Reprint of: Recessive APC2 missense variants associated with epilepsies without neurodevelopmental disorders.

Objectives: The APC2 gene, encoding adenomatous polyposis coli protein-2, is involved in cytoskeletal regulation in neurons responding to endogenous extracellular signals and plays an important role in brain development. Previously, the APC2 variants have been reported to be associated with cortical dysplasia and intellectual disability. This study aims to explore the association between APC2 variants and epilepsy.

Effects of diurnal temperature range on mortality in Hefei city, China.

Although several studies indicated an association between diurnal temperature range (DTR) and mortality, the results about modifiers are inconsistent, and few studies were conducted in developing inland country. This study aims to evaluate the effects of DTR on cause-specific mortality and whether season, gender, or age might modify any association in Hefei city, China, during 2007-2016. Quasi-Poisson generalized linear regression models combined with a distributed lag non-linear model (DLNM) were applied to evaluate the relationships between DTR and non-accidental, cardiovascular, and respiratory mortality.

Distribution of polybrominated diphenyl ethers in breast milk, cord blood and placentas: a systematic review.

Polybrominated diphenyl ethers (PBDEs) have been extensively used as flame retardants in consumer products. PBDEs rapidly bioaccumulate in the environment, food, wild animals and humans. In this review, we investigated the harmful effects of PBDEs on humans, especially in early life, and summarised the levels of PBDEs in human biological samples (breast milk, cord blood and placentas).

Two follicle-stimulating hormone receptor polymorphisms and polycystic ovary syndrome risk: a meta-analysis.

The aim of this study was to explore the association between follicle stimulating hormone receptor (FSHR) Thr307Ala and Asn680Ser polymorphisms and susceptibility to polycystic ovary syndrome (PCOS). A comprehensive literature search for relevant studies was conducted on Google Scholar, PubMed, the Chinese National Knowledge Infrastructure (CNKI) and the Chinese Biomedical Literature Database (CBM). This meta-analysis was performed using the STATA 11.

CTLA-4 polymorphisms and systemic lupus erythematosus (SLE): a meta-analysis.

The aim of this study was to summarize results on the association of cytotoxic T-lymphocyte antigen-4 (CTLA-4) promoter exon-1 +49 and 1722T/C polymorphism with systemic lupus erythematosus (SLE) susceptibility by using the meta-analysis. We searched all the publications about the association between CTLA-4) promoter exon-1 +49 and 1722T/C polymorphism and SLE from PubMed, Elsevier Science Direct, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), and Wanfang (Chinese). Previous CTLA-4 association studies with SLE, however, have produced inconsistent results.

No association between COMT Val158Met polymorphism and prostate cancer risk: a meta-analysis.

Objective: Results from published studies on the association between the catechol-O-methyltransferase (COMT) Val158Met polymorphism and prostate cancer (PCa) risk are inconsistent. To derive a more precise estimate, we performed a meta-analysis.

Methods: We searched in the PubMed and Elsevier Science Direct database for studies on the association between the COMT Val158Met polymorphism and PCa.

Meta-analysis of MCP-1 promoter -2518 A/G polymorphism and SLE susceptibility.

The aim of this meta-analysis was to summarize results on the association of monocyte chemoattractant protein-1(MCP-1) promoter -2518 A/G polymorphism with systemic lupus erythematosus (SLE) susceptibility. We searches all the publications about the association between MCP-1 promoter -2518 A/G polymorphism and SLE from Pubmed, Elsevier Science Direct, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure. The meta-analysis was performed for genotypes AA verse GG, AA+AG verse GG, AA verse AG+GG, and A allele verse G allele in a fixed/random effect model.

[Effects of mitogen-activated protein kinases signaling pathway proteins on kidney injury in mice exposed subchronically to cadmium].

Objective: To explore the effects of mitogen activated protein kinase (MAPK) and extracellular signal-regulated kinases (ERK) on kidney injury in female BALB/c mice exposed to cadmium.

Method: Twenty-one female BALB/c mice were randomly divided into 3 groups, i.e.

PDTC attenuate LPS-induced kidney injury in systemic lupus erythematosus-prone MRL/lpr mice.

Lipopolysaccharide (LPS) from bacteria can accelerate and exacerbate lupus nephritis (LN) and induce infiltrating inflammatory cells in kidney in animal models. Pyrrolidine dithiocarbamate (PDTC) is known to exert anti-inflammatory effects. Monocyte chemoattractant protein-1(MCP-1) is upregulated by various stimuli, including LPS, high glucose, and hyperosmolality.

[Studying the lipid peroxidation index, morphology and apoptosis in testis of male BALB/c mice exposed to polybrominated diphenyl ether (BDE-209)].

Objective: To explore the lipid peroxidation and the testicular morphological change induced by decabrominated diphenyl ether (BDE-209) in male BALB/c mice.

Methods: Twenty one male BALB/c mice were randomly divided into three groups: the high exposure group (500 mg/kg BDE-209), the low exposure group (200 mg/kg BDE-20) and control group (normal saline). The mice were exposed by gavage one time a day for 6 weeks, then were sacrificed.

[Oxidative stress of decabromodiphenylether in mice brain tissue].

Objective: To study the oxidative stress induced by decabromodiphenylether (PBDE-209) in the cerebral cortex, hippocampus, cerebellum and striatum of mice.

Methods: Twenty-eight male BALB/c mice were randomized divided into four groups with seven mice in each: solvent control, blank control, low (200 mg/kg) and high (500 mg/kg) dose groups. Test substances were administered by gavage and mice were sacrificed 6 weeks after treatment.

The learning and memory ability of mice were tested by the Morris water maze and the shuttling box respectively.

Simultaneous determination of phthalates and adipates in human serum using gas chromatography-mass spectrometry with solid-phase extraction.

A gas chromatography-mass spectrometry assay was developed and validated for the simultaneous determination of phthalates and adipates in human serum.
