Meta-analysis of human lung cancer microRNA expression profiling studies comparing cancer tissues with normal tissues
Peng Guan, Zhihua Yin, Xuelian Li, Wei Wu, Baosen Zhou
Journal of Experimental & Clinical Cancer Research , 2012, DOI: 10.1186/1756-9966-31-54
Abstract: A meta-analysis was conducted to review the published microRNA expression profiling studies that compared the microRNAs expression profiles in lung cancer tissues with those in normal lung tissues. A vote-counting strategy that considers the total number of studies reporting its differential expression, the total number of tissue samples used in the studies and the average fold change was employed.A total of 184 differentially expressed microRNAs were reported in the fourteen microRNA expression profiling studies that compared lung cancer tissues with normal tissues, with 61 microRNAs were reported in at least two studies. In the panel of consistently reported up-regulated microRNAs, miR-210 was reported in nine studies and miR-21 was reported in seven studies. In the consistently reported down-regulated microRNAs, miR-126 was reported in ten studies and miR-30a was reported in eight studies. Four up-regulated microRNAs (miR-210, miR-21, miR-31 and miR-182) and two down-regulated mcroiRNAs (miR-126 and miR-145) were consistently reported both in squamous carcinoma and adenocarcinoma-based subgroup analysis, with the other 14 microRNAs solely reported in one or the other subset.In conclusion, the top two most consistently reported up-regulated microRNAs were miR-210 and miR-21. The results of this meta-analysis of human lung cancer microRNA expression profiling studies might provide some clues of the potential biomarkers in lung cancer. Further mechanistic and external validation studies are needed for their clinical significance and role in the development of lung cancer.

Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-006-0374-3
Abstract: CH4 and CO oxidation reaction on perovskite-like oxides La2 x SrxMO4 (0.0 x 1.0; M = Cu, Ni) was investigated from cyclic voltammetry method, finding that for suprafacial CO oxidation reaction, the catalyst activity has a close correlation to the area of redox peaks measured in the cyclic voltammetry, the larger the peak area is, the higher the activity will be, while for interfacial CH4 oxidation reaction, the activity depends mainly on the difference in redox potentials (ΔE), and the smaller the difference in redox potentials is, the higher the activity will be.
Relationship between the Change in Health Status and Satisfaction with Physical Education in Chinese College Students  [PDF]
Xuelian Wang, Yoshio Sugiyama
Advances in Physical Education (APE) , 2014, DOI: 10.4236/ape.2014.43015
Abstract:

We examined the relationship between health status and satisfaction with physical education (PE) lessons. The participants (N = 142, Mean = 19.14 yrs, SD = 0.92) were university students in China. The participants completed questionnaires at the beginning and end of the PE class term to indicate their health status. Multiple linear regression analyses revealed that the changes in health status significantly correlated with satisfaction with PE lessons. Results of the multiple regression analyses indicated that satisfaction with PE lessons was significantly related to enjoyment. The practical implications of this study focused on developing a PE lesson program that would improve the health status of students well as be enjoyable to the students.

Comparing Health Status and Lifestyle in Chinese College Students  [PDF]
Xuelian Wang, Yoshio Sugiyama
Advances in Physical Education (APE) , 2015, DOI: 10.4236/ape.2015.54033
Abstract: The study aimed to compare health status and lifestyle in university students. The participants were college freshmen from physical education majors (N = 195, Mean = 20.9, SD = 1.87) and the school of Urban and Environmental majors (N = 195, Mean = 21.73, SD = 0.93) in Dalian, China. The Diagnostic Inventory of Health and Life habit (DIHAL.2) scale (Tokunaga, 2003) was administered to all participants. A one-way sample t-test was used to analyze the difference in both interdepartmental and gender effects. Results of t-test indicated that there were significantly difference in physical health, social health and life habit. Moreover, students majoring in physical education were scored lower on the mental health domain compared to the physical and social health domains. The practical implication of this study focused on finding the difference between the students who regularly exercised and those who did not, and considered the characteristics of gender. Finally, we hope that this study would be available for physical education in university.

Tang Xuelian
International Journal of Online Engineering (iJOE) , 2013, DOI: 10.3991/ijoe.v9is2.2561
Abstract: Talent resource is the primary resource. There are two sides as the starting point and foothold in this paper. One is how to evaluate the performance of science and technology talents flow by IDSS (Intelligence Decision Supporting System). Another is how to guide the innovation work of science and technology according to the evaluation results. The evaluation index on performance system has hierarchical structure. So AHP (Analytic Hierarchy Process) is applied to evaluate the performance. Evaluation model is established and illustrated by the cases in this paper. It can be seen that the flow of performance is influenced by the growth rate of important scientific and technological achievements. Furthermore, some constructive suggestions are given based on the results of evaluation.

Association between polymorphisms in XRCC1 gene and clinical outcomes of patients with lung cancer: a meta-analysis
Zhigang Cui, Zhihua Yin, Xuelian Li, Wei Wu, Peng Guan, Baosen Zhou
BMC Cancer , 2012, DOI: 10.1186/1471-2407-12-71
Abstract: We retrieved the relevant articles from PubMed, EMBASE and the China National Knowledge Infrastructure (CNKI) databases. Studies were selected using specific inclusion and exclusion criteria. Primary outcomes included objective response (i.e., complete response + partial response vs. progressive disease + stable disease) and overall survival (OS). Odds ratio (OR) or hazard ratio (HR) with 95% confidence interval (CI) were estimated. All analyses were performed using the Stata software.Twenty-two articles were included in the present analysis. XRCC1 Arg194Trp and Arg399Gln polymorphisms were significantly associated with response to treatment in lung cancer patients. Patients with C/T genotype, T/T genotype and minor variant T allele at Arg194Trp were more likely to respond to platinum-based chemotherapy compared with those with C/C genotype (C/T vs. C/C: OR, 2.54; 95%CI, 1.95-3.31; T/T vs. C/C: OR, 2.06; 95%CI, 1.39-3.06; C/T+T/T vs. C/C: OR, 2.42; 95% CI, 1.88-3.10). For XRCC1 Arg399Gln, G/A genotype, A/A genotype and minor variant A allele were associated with objective response in all patients (G/A vs. G/G: OR, 0.67; 95%CI, 0.50-0.90; A/A vs. G/G: OR, 0.43; 95%CI, 0.25-0.73; A/A+G/A vs. G/G: OR, 0.63; 95%CI, 0.49-0.83). Both G/A and A/A genotypes of XRCC1 Arg399Gln could influence overall survival of lung cancer patients (G/A vs. G/G: HR, 1.23; 95%CI, 1.06-1.44; A/A vs. G/G: HR, 2.03; 95%CI, 1.20-3.45). Interaction analysis suggested that compared with the patients carrying C/T+T/T genotype at XRCC1 194 and G/G genotype at XRCC1 399, the patients carrying 194 C/C and 399 G/A+A/A or 194 C/C and 399 G/G genotype showed much worse objective response.Genetic polymorphisms in XRCC1 gene might be associated with overall survival and response to platinum-based chemotherapy in lung cancer patients.Lung cancer as a major public health problem represents the most common cancer, and more than a million people in the world die from the disease each year [1].
