Polymorphisms in miRNA binding sites have been shown to affect miRNA binding to target genes, resulting in differential mRNA and protein expression and susceptibility to common diseases. Our purpose was to predict SNPs (single nucleotide polymorphisms) within miRNA binding sites of inflammatory genes in relation to gastric cancer. A complete list of SNPs in the 3'UTR regions of all inflammatory genes associated with gastric cancer was obtained from Pubmed. miRNA target prediction databases (MirSNP, Targetscan Human 6.2, PolymiRTS 3.0, miRNASNP 2.0, and Patrocles) were used to predict miRNA target sites. There were 99 SNPs with MAF>0.05 within the miRNA binding sites of 41 genes among 72 inflammation-related genes associated with gastric cancer. NF-${\kappa}B$ and JAK-STAT are the two most important signaling pathways. 47 SNPs of 25 genes with 95 miRNAs were predicted. CCL2 and IL1F5 were found to be the shared target genes of hsa-miRNA-624-3p. Bioinformatic methods could identify a set of SNPs within miRNA binding sites of inflammatory genes, and provide data and direction for subsequent functional verification research.

BaCeO3-based ceramics are a unique class of perovskites that exhibit protonic and oxygen ionic conduction,which are ideal for high temperature hydrogen separation applications. This work features Sc-dopedBCFe composites with nominal composition of BaCe0.70Fe0.30-xScxO3d (BCFSc) (x = 0, 0.05, 0.1, 0.15, and0.2) that exhibit enhanced thermal, chemical, and mechanical stability. The BCFSc20 (x = 0.20) hollowfiber membranes demonstrated the highest hydrogen and oxygen fluxes among the Sc-doped compositesof up to 0.32 and 0.20 mL min1 cm2, respectively, at 1000 C. The BCFSc20 hollow fibers also displayedexcellent stability under the hydrogen and oxygen permeation environments, while the permeation performanceof the other BCFSc samples with low Sc content gradually deteriorated over the 120-h stabilitytest.

Naringenin alleviates bone cancer pain in rats via down-regulating spinal P2X7R /PI3K/AKT signaling: involving suppression in spinal inflammation

Song Jian-Gang,Liu Lv 대한독성 유전단백체 학회 2021 Molecular & cellular toxicology Vol.17 No.4

Background Bone cancer pain (BCP) seriously affects patient’s quality of life, which remains a difficult clinical problem, lacking effective drugs for treating it. The inflammation in the spinal cord involves the pathogenesis of BCP. The inhibition of spinal phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway or spinal P2X7 receptor (P2X7R) has previously been shown to alleviate BCP. Naringenin (NAR) has analgesic role and anti-inflammatory property. Objective The present study investigated the protection of NAR against BCP and explored whether the inhibition of spinal inflammation and the blockade of spinal P2X7R/PI3K/AKT signaling involved in this protection. Result NAR significantly alleviated mechanical allodynia (the increase of paw withdrawal threshold in Von Frey test) and thermal hyperalgesia (the increase of paw withdrawal latency in Hargreaves test) in BCP rats. Additionally, NAR inhibited inflammatory cytokines (the reduced levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) were measured using Elisa assay) and down-regulated P2X7R/PI3K/AKT signaling (the decreased P2X7R expression, the reduced ratios of phosphorylated (p)-PI3K/PI3K and p-AKT/AKT, which were detected Western blot) in the spinal cord of BCP rats. Conclusion NAR alleviated BCP through inhibiting inflammatory cytokines and down-regulating P2X7R/PI3K/AKT signaling in the spinal cord of rats. These findings revealed that NAR, as an effective agent against BCP, may provide an effective approach in the management of bone cancer patients.

Competitive Adsorption of Binary Mixture of Leptospirillum ferriphilum and Acidithiobacillus caldus Onto Pyrite

Jian Song,Jianqun Lin,Jianqiang Lin,Yilin Ren 한국생물공학회 2010 Biotechnology and Bioprocess Engineering Vol.15 No.6

Leptospirillum ferriphilum and Acidithiobacillus caldus are two important acidophilic microorganisms involved in iron and sulfur oxidation during bioleaching. Cell adsorption to mineral surfaces is important for the direct leaching or contact leaching of minerals. In this study, we report the competitive adsorption of binary mixtures of L. ferriphilum LF-104 and A. caldus MTH-04onto pyrite surfaces. The Langmuir adsorption parameter (CAm) indicated that these two bacteria underwent competitive adsorption to pyrite. Real-time quantitive PCR was used to quantify the relative amounts of L. ferriphilum and A. caldus adsorbed onto the surfaces of pyrite following exposure to a mixture of these two organisms. The adsorption of L. ferriphilum was not affected by A. caldus. However, adsorption of A. caldus was greatly affected by the presence of L. ferriphilum. Zeta-potential measurements and FT-IR spectroscopic studies showed that L. ferriphilum had a higher electrostatic attraction towards pyrite when compared to A. caldus. Based on the above results, we propose a competitive adsorption model to explain the mechanism by which L. ferriphilum and A. caldus compete in their adsorption to pyrite, although L. ferriphilum dominated in the competitive adsorption process. This work provides a better understanding of the adsorption behavior of mixed microbial populations onto mineral surfaces.

Prognostic Value of Matrix Metalloproteinase 9 Expression in Breast Cancer Patients: A Meta-analysis

Song, Jian,Su, Hong,Zhou, Yang-Yang,Guo, Liang-Liang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3

Background: Matrix metalloproteinase 9 (MMP-9) is related to tumor invasion and metastasis. However, the role of MMP-9 expression in breast cancer survival remains controversial. The purpose of this study was to accomplish a more accurate estimation of the association between MMP-9 expression and survival results in breast cancer patients through meta-analysis. Methods: A meta-analysis of published studies investigating the effects of positive MMP-9 expression on both relapse free survival (RFS) and overall survival (OS) was performed. Relevant literature was confirmed by searching electronic databases including PubMed, Ovid, EMBASE and China National Knowledge Infrastructure (CNKI) before November 1, 2012. Individual hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted and pooled HRs with 95% CIs were used to evaluate the strength of the association between positive MMP-9 expression and survival results of breast cancer patients. Funnel plot and Egger's regression tests were used to evaluate publication bias. Heterogeneity and sensitivity analysis was also conducted. All the work was completed using STATA. Results: A total of 2,344 patients from 15 evaluative studies were finally included. Pooled HRs and 95% CIs suggested that MMP-9 overexpression had an unfavorable impact on both OS (HR: 1.70, 95% CI: 1.41-2.04) and RFS (HR: 1.54, 95% CI: 1.17-2.01) in breast cancer patients. There was no significant heterogeneity observed in the studies reported for OS (P=0.360, $I^2$=8.8%), but not RFS (P=0.002, $I^2$=67%). Publication bias was absent among the studies both in OS and RFS cases (t=-0.54, P=0.605 and t=1.71, P=0.131, respectively). Omission of any single study had little effect on the combined risk estimates on sensitivity analysis. Conclusion: The results of this meta-analysis suggest that positive MMP-9 expression confers a higher risk of relapse and a worse survival in patients with breast cancer. Larger prospective studies are now needed to evaluate the clinical utility of MMP-9 expression.

Active Damping Stability Control Method Based on Voltage Compensation for IPMSM Drives with Small DC-Link Capacitor

Song Jian,Song Wen-Xiang,Liu Zhan-Jun,Ma Shao-Cai 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.2

Aiming at the unstable phenomena such as high DC-link voltage ripple that occur in the interior permanent magnet synchronous motor drive system of the small DC-link capacitor when the rotor speed is high or the load power is large, this paper proposes an active damping control method based on voltage compensation. The method starts from the mathematical model of the driving system, based on the characteristic equation of the driving system, and according to the Rouse stability criterion, the driving system is stabilized by applying a virtual resistance to change the coefficient of the characteristic equation. The proposed method only needs a bandpass filter to extract the DC-link voltage ripple, which is then compensated to the motor stator voltage axis by the damping coefficient. In order to obtain high damping performance, considering the time constant and the delay of the control loop, the theoretical design basis for a reasonable value of the damping coefficient is given, and the influence of the proposed method on the performance of the drive system is evaluated. Simulation and experimental results verify the effectiveness of the proposed method.

Age of Diagnosis of Breast Cancer in China: Almost 10 Years Earlier than in the United States and the European Union

Song, Qing-Kun,Li, Jing,Huang, Rong,Fan, Jin-Hu,Zheng, Rong-Shou,Zhang, Bao-Ning,Zhang, Bin,Tang, Zhong-Hua,Xie, Xiao-Ming,Yang, Hong-Jian,He, Jian-Jun,Li, Hui,Li, Jia-Yuan,Qiao, You-Lin,Chen, Wan-Qin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

Background: The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Materials and Methods: Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. Results: The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. Conclusions: The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.
