Chinese Journal of Lung Cancer , 2011,
Abstract: Background and objective Xuanwei is an area of the highest incidence and mortality with lung cancer in China. The aim of this study is to determine serum selenium concentrations in lung cancer patients from Xuanwei as well as selenium levels of cancerous tissues, cancer-adjacent pulmonary tissues, and normal pulmonary lung tissues from lung cancer patients, and the relationship between selenium and the high incidence of lung cancer in Xuanwei. Methods One hundred and twenty female adults from Xuanwei were enrolled in the study (60 lung cancer patients and 60 with non-tumor and non-respiratory diseases, respectively) and blood samples were collected. Sixty fresh cancerous tissues and their adjacent as well as normal tissues were collected (31 samples from lung cancer patients living in Xuanwei for more than 2 years and 29 from patients in other regions of Yunnan Province outside of Xuanwei, respectively). Serum and tissue selenium concentrations were assayed using a fluorometric method. Results Women with lung cancer had a mean serum selenium value (55.22 μg/L±13.34 μg/L) of averagely 8.47%, significantly lower than that in subjects with non-tumor and non-respiratory disease controls (60.33 μg/L±13.82 μg/L)(P < 0.05). Selenium concentrations in the tumor tissues (0.105 μg/g±0.034 μg/g) were statistically lower than that of normal ones (0.140 μg/g±0.048 μg/g)(P < 0.05) from lung cancer patients in Xuanwei. Statistical differences had not been found between the cases from Xuanwei and non-Xuanwei district, adenocarcinoma and squamous cell carcinoma, among Stage I, Stage II, stage III groups. Conclusion Lower serum selenium state was negatively related to the incidence of lung cancer in Xuanwei. It was likely that lower selenium level of lung tissues was potential risk factor to lead to lung cancer.

Chinese Journal of Lung Cancer , 2009,
Abstract: Background and objective The therapeutic efficacy of late lung-cancer was very poor, and cytokine-induced killer cells (CIK) were paid more attention to treat non-small cell lung cancer (NSCLC). The aim of this study is to get insight into the role of bronchial arterial infusion bronchial arterial infusion (BAI) plus CIK about NSCLC by comparing therapeutic efficacy among BAI, traditional vein chemotherapy and BAI plus CIK, for late NSCLC. Methods A total of 120 patients were enrolled in this study, dividing randomly into three groups: bronchial arterial infusion (BAI), traditional vein chemotherapy and BAI plus CIK. Clinical effects and side effects were estimated after two period of therapy. Results The effective rate (CR+PR%) of combined group is higher than the traditional vein chemotherapy group (66.67%, n=39) and there are significant differences (χ2=4.721, P=0.03); The side effect of rate of BAI plus CIK group is significantly lower than the traditional vein chemotherapy group, and so did the non-bone marrow inhibition side effects (P < 0.05). The tumor progression rate (PD%) of bronchial arterial infusion (BAI) group is higher than combined group (χ2=4.287, P=0.038). There was no difference between the traditional vein chemotherapy group and combined group (χ2=0.082, P=0.775). Conclusion Bronchial Artery Infusion combined with cytokine-induced killer cells is an ideal, safety, effective comprehensive treatment method for late stage lung cancer.
Retail Pricing under Contract Self-Selection: An Empirical Exploration  [PDF]
Yuanfang Lin, Lianhua Li
Technology and Investment (TI) , 2013, DOI: 10.4236/ti.2013.41B007
Abstract: Using cross-sectional survey data on prices, station and market characteristics for 730 gasoline stations in the Greater Saint Louis area, we estimate a switching regression model of station decisions. We employ a binary probit choice model to study a station’s decision to enter a contract relationship with greater control from the upstream refinery, or a contract relationship with greater degree of independence, as a function of market and station characteristics. We then estimate stations’ pricing decisions with self-selectivity corrections for the station’s contract decision. We show that incorrect inferences about retail gasoline station’s pricing behavior would result if the endogeneity in the choice of con-tract type were treated as exogenous condition in the estimation.

Evaluation Model of Emergency Evacuation Capacity of Subway Station Based on Grounded Theory  [PDF]
Lianhua Cheng, Yuhang Gao
World Journal of Engineering and Technology (WJET) , 2019, DOI: 10.4236/wjet.2019.72B004
Abstract:
In order to evaluate the emergency evacuation capacity of subway stations, the data collected were analyzed based on grounded theory, and an evaluation model of emergency evacuation capacity was constructed by combining the analytic hierarchy process (AHP). Finally, 12 secondary indicators (categories) and 4 primary indicators (main categories) were obtained, among which the primary indicators were management factors, emergency response, construction factors and personnel factors. From the weight value calculated by analytic hierarchy process, we can see that management factors and emergency response have great influence on the emergency evacuation capacity of subway stations. Therefore, we should focus on management factors and emergency response to improve the emergency evacuation capacity of subway stations.

Abstract: Background and objective The high incidence of lung cancer in Xuanwei, China, has become an important restricting factor for livelihood development, thus exerting local social and economic impacts. Coal is the main fuel of the local community and also the main source of indoor pollution. This study aims to explore the coal combustion inhalable fine particulate matter (PM2.5) and its component output differences in different areas of Xuanwei, Yunnan. Moreover, the aim of this study is to investigate the relationship between inhalation of fine particles and high incidence of local lung cancer. Methods For combustion test, coal mines designated as C1, K7 and M30 were collected from LaoLin Colliery of Laibing Town, Huchang Colliery of Baoshan Town, and Taiping Colliery of Wenxing Town in Xuanwei, respectively. PM2.5 of indoor air was weighed, analyzed for elemental composition, and morphologically compared. The pathological specimen of lung cancer patients in Xuanwei who underwent operation was observed through electron microscope. Results The PM2.5 concentrations in indoor air were (8.244 ±1.460) mg/m3 (C1), (5.066±0.984) mg/m3 (K7), and (5.071±1.460) mg/m3 (M30). The differences among pairwise comparisons were statistically significant (P=0.029). The filter impurities of C1 coal seam primarily include Si- and O-enriched compounds. Moreover, three membranes that comprised other elements, including C, S, and Si, were observed. These membranes were evident from the aggregation of silica and a Ca-Al membrane. Compared with that of other coal seams, C1 coal generated a mass of impurities, in which several particles have irregular shape. We found nanoscale fine particles in some specimens of Xuanwei lung cancer patients. Conclusion The produced combustion of C1 coal was different from that of K7 and M30 coal. PM2.5 composition may be associated with the high local incidence of lung cancer.

Mathematics , 2010,
Abstract: In this paper, we study adaptive finite element approximations in a perturbation framework, which makes use of the existing adaptive finite element analysis of a linear symmetric elliptic problem. We prove the convergence and complexity of adaptive finite element methods for a class of elliptic partial differential equations. For illustration, we apply the general approach to obtain the convergence and complexity of adaptive finite element methods for a nonsymmetric problem, a nonlinear problem as well as an unbounded coefficient eigenvalue problem.
