Artificial neural network（ANN） and full factorial design assisted atrazine（AT） multiple regression adsorption model（AT-MRAM） were developed to analyze the adsorption capability of the main components in the surficial sediments（SSs）. Artificial neural network was used to build a model（the determination coefficient square r2 is 0.9977） to describe the process of atrazine adsorption onto SSs, and then to predict responses of the full factorial design. Based on the results of the full factorial design, the interactions of the main components in SSs on AT adsorption were investigated through the analysis of variance（ANOVA）, F-test and t-test. The adsorption capability of the main components in SSs for AT was calculated via a multiple regression adsorption model（MRAM）. The results show that the greatest contribution to the adsorption of AT on a molar basis was attributed to Fe/Mn（–1.993 μmol/mol）. Organic materials（OMs） and Fe oxides in SSs are the important adsorption sites for AT, and the adsorption capabilities are 1.944 and 0.418 μmol/mol, respectively. The interaction among the non-residual components（Fe, Mn oxides and OMs） in SSs interferes in the adsorption of AT that shouldn’t be neglected, revealing the significant contribution of the interaction among non-residual components to controlling the behavior of AT in aquatic environments.

Asthma and chronic obstructive pulmonary disease t（COPD） are the two commonest causes of adultairflow obstruction. The fundamental dltterences anti similarities between the pathological mechanisms of asthma and COPD are well recognized.^1 Both asthma and COPD involve inflammation of airway, but the pattern and distribution of inflammation markedly differ between typical patients with asthma and COPD. Chronic lung disease is now the most important long-term pulmonary complication in daily practice, and is associated with prolonged hospitalization and long-term pulmonary and clinical problems.^2

The number of individuals affected by chronic obstructive pulmonary disease （COPD） has been increasing in the last decades. As a consequence, COPD is expected to become the third most frequent cause of death worldwide by 2020.1 Exacerbations of COPD is a major cause of morbidity. In particular, they greatly contribute to decline of health-related quality of life,increase in symptoms and breathlessness, Progression of the disease, and increased risk of mortality.2

Our understanding of idiopathic pulmonary fibrosis （IPF） has undergone major changes in recent years. IPF is the most common of the idiopathic interstitial pneumonias. It remains the most often diagnosed, accounting for 50% to 60% of all cases. It is also associated with a worse prognosis than most of the interstitial lung diseases. The number of deaths related to IPF is nearly 14 times greater than those from asbestosis, while a recent estimate has suggested prevalence in the United States ranging from 14.0 to 42.7 cases per 100 000 population, depending on the criteria used for diagnosis,

Objective This review focuses on current knowledge of specific processes that drive chronic airway inflammation which are important in the pathogenesis of both chronic obstructive pulmonary disease （COPD） and lung cancer. Data sources The data used in this review were obtained mainly from studies reported in the PubMed database （1997-2012） using the terms of COPD and lung cancer. Study selection Data from published articles about prevalence of COPD-lung cancer overlap and mechanism involved in lung cancer development in COPD were identified, retrieved and reviewed. Results COPD prevalence, morbidity and mortality vary and are directly related to the prevalence of tobacco smoking except in developing countries where air pollution resulting from the burning of biomass fuels is also important. COPD is characterized by a chronic inflammation of lower airway and, importantly, the presence of COPD increases the risk of lung cancer up to 4.5 fold among long-term smokers. COPD is by far the greatest risk factor for lung cancer amongst smokers and is found in 50%-90% of patients with lung cancer. Conclusions Both COPD and lung cancer are tobacco smoking-associated chronic diseases that cluster in families and aggravate with age, and 50%-70% of patients diagnosed with lung cancer have declined spirometric evidence of COPD. Understanding and targeting common pathogenic mechanisms for lung cancer and COPD would have potential diagnostic and therapeutic implications for patients with these lung diseases and for people at risk.

The medical community should, by now, be well aware of the importance of chronic obstructive pulmonary disease （COPD）, an increasingly common condition with high morbidity and mortality. In modern terms, COPD has come to signify concurrent chronic bronchitis, asthmatic bronchitis and emphysema. Cigarette smoking has long been recognized as the predominant aetiological agent. Arterial hypoxaemia, a frequent complication of COPD, can lead to pulmonary hypertension and cor pulmonale. COPD affects over 5% of the adult population and is the only major cause of death whose morbidity and mortality are increasing in several countries. In China, it is difficult to quantify how many people are affected with COPD. However, a recent epidemiological survey indicated that COPD prevalence was 8.2% in China. COPD prevalence in men was significantly higher than in women （12.4% cf 5.1%）. The prevalence in rural areas was higher than that in urban areas （8.8% cf 7.8%）. Of patients with COPD, 61.5% were smokers. The report also stated that COPD is the major cause of death in rural areas in China and the fourth leading cause of death in urban areas, rising to the third leading cause of death by 2020. The prevalence of the disease increases with age with highest rates seen in people over the age of 70 years. COPD is the only major cause of mortality with a rising incidence and prevalence worldwide, rendering it an increasingly worrisome.

This work was to determine which concentration of a mixture of fresh Humulus scandens （HS） and fresh alfalfa could be included in diets for rabbits. The fresh forage of three experimental diets is composed of 100% alfalfa, 50% alfalfa ＋ 50% HS, 100% HS, respectively. 30 rabbits [（1.42 ± 0.056） kg] were used to determine nutrient digestibility. A feeding trial was carried out using 90 weaning rabbits [35 d of age; （512±6.5） g]. Increasing content of HS in the diet did not affect digestibility of DM （dry matter）, CF （crude fiber）, CP （crude protein）, GE （gross energy）, and EE （ether extract）. But diarrhea decreased markedly （P〈0.01） compared with the diets that had no HS. ADF1 （average daily feed intake） increased by 4.3% （P 〈 0.05） and 3.6% （P 〈 0.05） when rabbits fed the diet with 100% HS of fresh forage compared with the diets containing 0 and 50% HS, respectively. Feed efficiency improved significantly （P 〈 0.05） by 2.07 and 5.30% when rabbits fed 0 and 50% HS of fresh forage, respectively, compared with 100% HS. There was no effect on ADG （average daily weight gain）. In conclusion, the mixture （50：50） of HS and alfalfa constitutes an alternative source of fiber for fattening rabbits and prevents diarrhea effectively.
