Age-, season- and gender-specific reference intervals of serum 25-hydroxyvitamin D for healthy children (0 ~ 18 years old) in Nanning area of China.

Establishing specific reference intervals (RIs) of serum 25-hydroxyvitamin D3 [25(OH)D] for children is essential for improving the accuracy of diagnosis and prognosis monitoring of diseases such as rickets and growth retardation. The study including 6,627 healthy children was conducted to establish specific RIs of 25(OH)D for children in Nanning area of China. The results showed that there were statistically significant differences among age, season, and gender of serum 25(OH)D levels, and the age-specific RIs of serum 25(OH)D were 20.

CD54+ rabbit adipose-derived stem cells overexpressing HIF-1α facilitate vascularized fat flap regeneration.

Fat flap transplantation is frequently performed in patients suffering from soft tissue defects resulting from disease or trauma. This study explored the feasibility of constructing vascularized fat flaps using rabbit adipose-derived stem cells (rASCs) and collagen scaffolds in a rabbit model. We evaluated rASCs proliferation, paracrine function, adipogenesis, vascularization, and CD54 expression, with or without HIF-1α transfection in vitro and in vivo.

Ginsenoside Rg1 and platelet-rich fibrin enhance human breast adipose-derived stem cell function for soft tissue regeneration.

Adipose-derived stem cells (ASCs) can be used to repair soft tissue defects, wounds, burns, and scars and to regenerate various damaged tissues. The cell differentiation capacity of ASCs is crucial for engineered adipose tissue regeneration in reconstructive and plastic surgery. We previously reported that ginsenoside Rg1 (G-Rg1 or Rg1) promotes proliferation and differentiation of ASCs in vitro and in vivio.

Impact of caspase-8 (CASP8) -652 6N del and D302H polymorphisms on prostate cancer in different ethnic groups.

Background: Despite evidence suggesting roles for caspase-8 (CASP8) -652 6N del and D302H polymorphisms in prostate cancer (PCa), the association of these polymorphisms with PCa risk remains inconclusive. Therefore, a meta-analysis was performed to more precisely estimate the association of CASP8 -652 6N del and D302H polymorphisms with PCa susceptibility.

Materials And Methods: A comprehensive literature search was conducted to identify all case-control studies of CASP8 D302H and -652 6N del polymorphisms and PCa risk.

Positive association between IL-16 rs11556218 T/G polymorphism and cancer risk: a meta-analysis.

Background: Interleukin-16 (IL-16) is a multifunctional cytokine which plays a key role in inflammatory and autoimmune diseases as well as in cancer. Genetic polymorphisms of IL-16 have been implicated in susceptibility to cancer. However, associations remain inconclusive.

Lack of association between CYP1A1 polymorphisms and risk of bladder cancer: a meta-analysis.

Background: The effects of CYP1A1 gene polymorphisms on the risk of bladder cancer (BC) remain controversial. We carried out a meta-analysis to clarify the role of CYP1A1 gene polymorphisms in BC.

Material And Methods: A comprehensive literature search was conducted up to November 20, 2013.

The role of retinoic acid receptors in the signal pathway of all-trans retinoic acid-induced differentiation in adriamycin-induced podocyte injury.

All-trans retinoic acid (ATRA) plays an essential role in cell survival and differentiation by binding to retinoic acid receptors (RARs), including RAR-α, RAR-β, and RAR-γ. Injury to podocytes is the most frequent cause of glomerulosclerosis (GS). This study was performed to investigate which of the RAR subtypes is involved in the signal pathway of ATRA-induced differentiation of injured podocytes.

An updated meta-analysis between the association of XRCC1 Arg399Gln polymorphism and hepatocellular carcinoma risk.

Background: Various studies have evaluated the relationship between X-ray repair cross-complementing group 1 (XRCC1) Arg399Gln polymorphism and hepatocellular carcinoma (HCC) risk, but the conclusions have been inconsistent and underpowered. The purpose of this updated meta-analysis was to examine whether XRCC1 Arg399Gln polymorphism confers susceptibility to HCC.

Methods: Eligible studies extracted from PubMed, Embase, Cochrane Library, VIP (chinese) and CNKI (chinese) up to November 2013 were included in the study.

Lack of association of INS VNTR polymorphism with polycystic ovary syndrome: a meta-analysis.

Purpose: An association between the INS VNTR polymorphisms and polycystic ovary syndrome (PCOS) susceptibility has been reported in previous studies, but the results were inconsistent. This study was conducted to explore this association using meta-analysis.

Methods: PubMed, Embase, and China National Knowledge Infrastructure (CNKI) were searched according to predefined criteria for all relevant studies published up to August 2013.

S-1-based therapy versus S-1 monotherapy in advanced gastric cancer: a meta-analysis.

This study aimed to derive a more precise estimate of the prognostic significance of S-1-based therapy over S-1 monotherapy in patients with advanced gastric cancer (AGC), including overall survival (OS) time, progression-free survival (PFS) time, objective response rate (ORR), and adverse events (AEs). Studies stratifying OS, PFS, ORR, and AEs in AGC patients in an S-1-based therapy versus an S-1 monotherapy setting were eligible for analysis by systematic computerized PubMed, Embase and Cochrane Library searches. Data from these studies were pooled using STATA package version 11.

Meta-analysis of randomized controlled trials on the efficacy of probiotics in Helicobacter pylori eradication therapy in children.

Unlabelled: The efficacy of probiotics supplementation in children undergoing Helicobacter pylori (H. pylori) eradication therapy remains controversial. This study aimed to meta-analyze whether probiotics supplementation in triple therapy could improve H.

Association of XRCC3 Thr241Met polymorphisms and gliomas risk: evidence from a meta-analysis.

Unlabelled: The relationship between the X-ray repair cross-complementing group 3 (XRCC3) Thr241Met polymorphism and gliomas remains inclusive or controversial. For better understanding of the effect of XRCC3 Thr241Met polymorphism on glioma risk, a meta-analysis was performed. All eligible studies were identified through a search of PubMed, Elsevier Science Direct, Excerpta Medica Database (Embase) and Chinese Biomedical Literature Database (CBM) before May 2013.

Myeloperoxidase polymorphism, menopausal status, and breast cancer risk: an update meta-analysis.

Myeloperoxidase (MPO) is a metabolic/oxidative lysosomal enzyme secreted by reactive neutrophils at the sites of inflamed organs and tissues during phagocytosis. MPO has been either directly or indirectly linked to neoplasia, which is a well-established risk factor for many types of cancer. A large number of studies have reported the role of MPO G-463A polymorphism regarding breast-cancer risk.
