T. Cui, Jiang, M. S., Cui, T., and Jiang, M. S., Myoglobin A79G polymorphism association with exercise-induced skeletal muscle damage, vol. 15, p. -, 2016.

We assessed the role of A79G, a polymorphism of the myoglobin gene (MB), in susceptibility to exercise-induced skeletal muscle damage. Between January 2012 and December 2014, a total of 166 cases with exercise-induced skeletal muscle damage and 166 controls were recruited into our study.

The mud crab (Scylla paramamosain) is of economic importance for the fisheries and aquaculture industry in China. In this study, we constructed the first genetic linkage map for this species using microsatellite and amplified fragment length polymorphism (AFLP) markers. The map consisted of 65 linkage groups, including 34 triplets and 9 doublets. A total of 212 molecular markers were mapped, including 60 microsatellites and 152 AFLP markers. The linkage groups ranged from 7 to 102.5 cM and covered 2746.4 cM in length.

Z. Cheng, Dai, L. L., Liu, Q., Liu, M., Wang, Q., Li, P. F., Wang, H., Jia, L. Q., An, L., Cheng, Z., Dai, L. L., Liu, Q., Liu, M., Wang, Q., Li, P. F., Wang, H., Jia, L. Q., and An, L., Correlation between polymorphisms in the glucocorticoid receptor gene NR3C1 and susceptibility to asthma in a Chinese population from the Henan Province, vol. 15, p. -, 2016.

The aim of this study was to investigate the association between four single nucleotide polymorphisms in NR3C1 (Tth111I, BclI, ER22/23EK, and N363S), which encode the glucocorticoid receptor, and asthma susceptibility in patients from the Henan Province of China. Three hundred and twenty-eight patients with asthma and 60 healthy volunteers were recruited to this study. The target SNPs were genotyped by polymerase chain reaction (PCR)-high resolution melting and PCR-restriction fragment length polymorphism.

Meta-analysis of the IL-10 promoter polymorphisms and pediatric asthma susceptibility

Z. Y. Huang, Cheng, B. J., Wan, Y., Zhou, C., Huang, Z. Y., Cheng, B. J., Wan, Y., and Zhou, C., Meta-analysis of the IL-10 promoter polymorphisms and pediatric asthma susceptibility, vol. 15, p. -, 2016.

The results of previous epidemiological studies exploring the relationship between interleukin-10 (IL-10) promoter polymorphisms and susceptibility to pediatric asthma are not consistent. Therefore, we have performed a systematic review and meta-analysis to provide a more convincing conclusion. Odds ratios (OR) with their 95% confidence intervals (CIs) were used to evaluate the strength of association between the IL-10 promoter polymorphisms and susceptibility to pediatric asthma. Publication bias was examined by Begg’s funnel plots and the Egger test.

Association of XRCC1 gene polymorphisms and pancreatic cancer risk in a Chinese population

L. J. Wang, Wang, H. T., Wang, X. X., Wang, L. J., Wang, H. T., and Wang, X. X., Association of XRCC1 gene polymorphisms and pancreatic cancer risk in a Chinese population, vol. 15, p. -, 2016.

We conducted a case-control study to assess the role of the XRCC1 Arg399Gln, Arg280His, and Arg194Trp gene polymorphisms in pancreatic cancer susceptibility in a Chinese population. A total of 152 patients diagnosed with pancreatic cancer and 264 control subjects were enrolled in this study between March 2012 and October 2014. XRCC1 Arg399Gln, Arg280His, and Arg194Trp were genotyped using the polymerase chain reaction-restriction fragment length polymorphism method.

S. H. Ma, Ling, F. H., Sun, Y. X., Chen, S. F., Li, Z., Ma, S. H., Ling, F. H., Sun, Y. X., Chen, S. F., and Li, Z., Investigation on the role of XPG gene polymorphisms in breast cancer risk in a Chinese population, vol. 15, p. -, 2016.

We conducted a case-control study to investigate the role of XPG gene polymorphisms (rs2094258, rs751402, and rs17655) in the development of breast cancer. Patients with breast cancer (320) and control subjects (294) were consecutively selected from the Zhongshan Hospital between April 2013 and January 2015. The genotyping of XPG rs2094258, rs751402, and rs17655 was performed using polymerase chain reaction-restriction fragment length polymorphism.

S. H. Yildiz, M. Erdogan, O., Solak, M., Eser, O., Terzi, E. S. Arıkan, Eser, B., Kocabaş, V., Aslan, A., Yildiz, S. H., M. Erdogan, O., Solak, M., Eser, O., Terzi, E. S. Arıkan, Eser, B., Kocabaş, V., and Aslan, A., Lack of association between the methylenetetrahydropholate reductase gene A1298C polymorphism and neural tube defects in a Turkish study group, vol. 15, p. -, 2016.

The etiology underlying neural tube defects (NTDs) is not fully understood and is believed to involve a complex milieu of genetic and environmental factors. The A1298C polymorphism in the methylenetetrahydropholate reductase gene (MTHFR) has been associated with mild risk for NTDs. In this study, the genotype distribution of the MTHFR gene A1298C polymorphism and the levels of serum homocysteine, vitamin B12, and folate were evaluated in 33 children with NTDs, their mothers, and 46 healthy controls.

We investigate the role of the GSTM1, GSTT1, and GSTP1 IIe105Val genetic polymorphisms in the susceptibility to gestational diabetes mellitus. A total of 223 pregnant women with gestational diabetes mellitus and 265 healthy pregnant women were examined at The Second Affiliated Hospital of Shaanxi University of Chinese Medicine from May 2013 to November 2013. Genotyping for detection of GSTM1, GSTT1, and GSTP1 IIe105Val polymorphisms was conducted using the restriction fragment length polymorphism-polymerase chain reaction.
