  • Meta-analyses have shown that microRNA polymorphisms have variable effects in different population. Yet, no meta-analysis investigated the association of two common polymorphisms of miRNA, mir-499 rs3746444 polymorphism and mir-149 rs2292832 polymorphism, with cancer risk in the Chinese population. We searched the PubMed, Web of Knowledge, MEDLINE, CNKI databases, as well as Cochrane library, updated on December 31, 2012 for assays regarding cancer risk association with these two common polymorphisms in the present meta-analysis. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to explore the strength of associations. The results showed that rs3746444 polymorphism was associated with increased cancer risk (dominant model: GG/AG vs. AA: OR = 1.43, 95% CI: 1.14-1.80; recessive model: GG vs. AG/AA: OR = 1.54, 95% CI: 1.04-2.30; homozygote model: GG vs. AA: OR = 1.69, 95% CI: 1.10-2.60; heterozygote model: AG vs. AA: OR = 1. 35, 95% CI: 1.09-1.67), and rs3746444 was associated with liver cancer in the subgroup of cancer types. For the rs2292832 polymorphism, the results showed no significant risk association in both overall pooled analysis and subgroup of cancer types, smoking status, gender and tea drinking status in the Chinese population. This meta-analysis suggested that the rs3746444 GG genotype is associated with increased cancer risk, especially liver cancer, while the rs2292832 polymorphism showed no association with cancer risk in Chinese.

  • Below are the reports arranged from the research of ${\ll}$XiFangZiMingTangJiuJing(西方子明堂灸經)${\gg}$, which appears in the research of the main issue. ${\ll}$XiFangZiMingTangJiuJing${\gg}$ was written during the Nan-song period, approximately between 1142~1194, and was probably completed between 1142~1148. This book is the very first book specific on the moxibustion theory which exists these days and also thoroughly contains the moxibustion theory. So it contains many documents of the moxibustion theory which are missing these days. Also it's possible that the illustration presented in this book followed ${\ll}$MingTangJing(明堂經)${\gg}$ of SunSiMiao(孫思邈). The way of arranging the GuiJing(歸經) of YuZue(兪穴) and deciding the location of acupuncturing(穴位) differs from reports given by other documents. As seen above, ${\ll}$XiFangZiMingTangJiuJing${\gg}$ has a consulting value on the moxibustion theroy(灸法), both in clinic and the research of documents. So we are looking forward that there would be a more profound research continuing in the future.

  • Porcine beta-defensin-1 (PBD-1) gene plays an important role in the innate immunity of pigs. The peptide encoded by this gene is an antimicrobial peptide that has direct activity against a wide range of microbes. This peptide is involved in the co-creation of an antimicrobial barrier in the oral cavity of pigs. The objective of the present study was to detect polymorphisms, if any, in exon-1 and exon-2 regions of PBD-1 gene in Large White Yorkshire (LWY) and native Ankamali pigs of Kerala, India. Blood samples were collected from 100 pigs and genomic DNA was isolated using phenol chloroform method. The quantity of DNA was assessed in a spectrophotometer and quality by gel electrophoresis. Exon-1 and exon-2 regions of PBD-1 gene were amplified by polymerase chain reaction (PCR) and the products were subjected to single strand conformation polymorphism (SSCP) analysis. Subsequent silver staining of the polyacrylamide gels revealed three unique SSCP banding patterns in each of the two exons. The presence of single nucleotide polymorphisms (SNPs) was confirmed by nucleotide sequencing of the PCR products. A novel SNP was found in the 5'-UTR region of exon-1 and a SNP was detected in the mature peptide coding region of exon-2. In exon-1, the pooled population frequencies of GG, GT, and TT genotypes were 0.67, 0.30, and 0.03, respectively. GG genotype was predominant in both the breeds whereas TT genotype was not detected in LWY breed. Similarly, in exon-2, the pooled population frequencies of AA, AG, and GG genotypes were 0.50, 0.27, and 0.23, respectively. AA genotype was predominant in LWY pigs whereas GG genotype was predominant in native pigs. These results suggest that there exists a considerable genetic variation at PBD-1 locus and further association studies may help in development of a PCR based genotyping test to select pigs with better immunity.

  • Background: Many studies have investigated the association between the MDM2 promoter SNP309 T/G polymorphism and liver cancer risk, but inconsistencies make drawwing definitive conclusions difficult. Methods: We therefore searched main databases for articles relating MDM2 SNP309 T/G polymorphism to risk of liver cancer in humans and estimated summary odds ratio (OR) with 95% confidence intervals (95% CI) to assess the possible association in a meta-analysis. Results: The main analysis revealed no significant heterogeneity, and the pooled ORs of fixed-effects were all significant (for G versus T, OR = 1.59, 95% CI 1.42-1.78; for GG versus TT, OR = 2.45, 95% CI 1.93-3.12; for GT versus TT, OR = 1.70, 95% CI 1.38-2.09; for GG versus GT, OR = 1.49, 95% CI 1.24-1.79; for GG and GT versus TT, OR = 1.95, 95% CI 1.61-2.38; for GG versus TT and GT, OR = 1.73, 95% CI 1.46-2.07). Subgroup analyses by ethnicity and sensitivity analyses both showed associations to remain significant. Conclusion: The present meta-analysis of available data showed a significant association between the MDM2 SNP309 T/G polymorphism and liver cancer risk, the MDM2 SNP309 G allele contributing to increased risk in both Asians and Caucasians in a graded, dose-dependent fashion.

  • Background: Vascular endothelial growth factor (VEGF), an endothelial cell specific mitogen, has been implicated as a critical factor influencing tumor related angiogenesis. The aim of present study was to evaluate the relationship between VEGF +936C>T and +405C>G polymorphisms of VEGF with risk of breast cancer in Punjab, India. Materials and Methods: We screened DNA samples of 192 sporadic breast cancer patients and 192 unrelated healthy, gender and age matched control individuals for VEGF +936C>T and +405C>G polymorphisms using the PCR-RFLP method. Results: For the VEGF +405C>G polymorphism, we observed significantly increased frequency of GG genotype in cases as compared to controls and strong association of +405GG genotype was observed with three fold risk for breast cancer (OR=3.07; 95%CI 1.41-6.65; p=0.003). For the +936C>T polymorphism, significant associations of CT and combined CT+TT genotypes were observed with elevated risk of breast cancer (p=0.021; 0.023). The combined genotype combinations of GG-CC and GG-CT of +405C>G and +936C>T polymorphisms were found to be significantly associated with increased risk of breast cancer (p=0.04; 0.0064). Conclusions: The findings of the present study indicated significant associations of VEGF +936C>T and +405C>G polymorphisms with increased breast cancer risk in patients from Punjab, North India.

  • In recent years, mounting evidence has indicated that the CCND1 G870A gene polymorphism, which impacts the mitotic cell cycle, may influence leukemia or non-Hodgkin lymphoma risk. Unfortunately, the previous results were inconsistent. Therefore, a meta-analysis was performed to obtain a more precise estimation of any association. We conducted a search in PubMed, Embase and CNKI covering all published papers up to March, 2014. A total of 9 publications including 10 case-control studies met the inclusion criteria. Odds ratios (ORs) and their 95% confidence intervals (95%CIs) were applied to assess association. The pooled ORs showed significant association in non-Hodgkin lymphoma (comparison A vs G: OR= 1.114, 95%CI=1.053-1.179, p=0.000; homozygote comparison AA vs GG: OR=1.245, 95%CI=1.110-1.396, p=0.000; heterozygote comparison AG vs GG: OR=1.095, 95%CI=1.000-1.199, p=0.05; dominant model AA/GA vs GG: OR=1.137, 95%CI=1.043-1.239, p=0.003; and recessive model AA vs GA/GG: OR=1.177, 95%CI=1.066-1.301, p=0.001). However, there was no association between the CCND1 G870A polymorphism and leukemia risk. In conclusion, the CCND1 G870A polymorphism may increase risk of non-Hodgkin lymphoma, but not leukemia. However, more primary large scale and well-designed studies are still required to evaluate the interaction of CCND1 G870A polymorphism with leukemia and non-Hodgkin lymphoma risk.

  • 녹색성장정책은 환경(Green)과 성장(Growth)의 양립구조에서 벗어나 환경 그 자체를 새로운 성장동력으로 인식하고 환경과 성장의 선순환구조로 경제성장 패러다임을 전환시키는 것이다. 그러나 녹색성장정책은 국가에 따라 다소 상이하게 추진되므로 이러한 정책들을 살펴보고, 실제 일반인과 기업에서 이것을 어떻게 수용하는지 실증분석을 통하여, 우리나라 녹색성장전략을 제시하는데 그 목적이 있다. 실증분석 결과, 나타난 주요 시사점을 요약하면 다음과 같다. 첫째, 녹색성장정책은 단순한 환경문제를 해결하기 위한 정책이 아닌 범국가적인 전략 추진이 필요하다. 둘째, 녹색성장정책의 핵심부문으로서 에너지정책을 규정하고 단기적으로 성과가 가능한 에너지 사용의 효율화를 적극 추진하여야 한다. 셋째, 녹색성장정책에 IT활용을 적극적으로 추진하여 보다 장기적인 성과에 초점을 둔 전략 개발이 필요하다. 넷째, 우리나라의 실행계획의 수립은 녹색성장정책 추진에 따른 효율성과 직접적인 관련이 있으므로 매우 신중한 접근이 요구된다. 다섯째, 녹색성장정책을 사회변혁정책으로 다루어 범국민적인 여론 형성을 마련하여야 한다.
