There is a large quantity of smokers and the distribution of tobacco smoke is widespread which causes the tobacco odor to become a typical unpleasant odor to the environment. Tobacco smoke in the environment is easily absorbed into fabrics with porous structural characteristics and the tobacco smoke will release continuously and slowly. The tobacco smoke in this process is also known as third-hand smoke . The presence of third-hand smoke will not only emit an unpleasant smell and detract from the image of the person wearing these clothes but also increase the number of textiles washing resulting in additional carbon emissions and even harm to the human body. We took cotton a common textile fabric as the research object and used the adsorption device and deodorization device to carry out the experiment. It should be noted that the main function parameters of the deodorization device include water vapor hot air and plasma which can be set freely according to the experimental design. Secondly we collected the smell scores of four evaluators subjective smell as subjective evaluation data and recorded the changes of nicotine peak area before and after deodorization operation and then used the calculated results as objective evaluation data. Thirdly according to the multiple stepwise regression analysis model we screened and analyzed the factors significantly affecting the effect of deodorization according to the response surface model. Finally the tobacco odor released from cotton fabrics was analyzed by headspace-gas chromatography / mass spectrometry HS-GC / MS. The results show that the R² of the response surface model is 0. 74 and the F-statistic is 38. 04 which shows that the model has high precision and good prediction and analysis effect. The results of the response surface analysis show that the effect of water vapour hot air and plasma on the removal of tobacco odor is significant and the effect of both water vapour and hot air on the removal of tobacco odor is positive but the excessively long water vapor duration will lead to the decline of the deodorization effect. The results show that the nicotine removal rate can reach 100% and the subjective evaluation score is only 1 when the water vapor is applied for 5 min the hot air for 39 min and the ion generator for 42 min. That is to say the effect of cigarette smell removal is the best. The results of GC-MS analysis show that the components of third-hand smoke include many kinds of compounds such as pyridine aldehyde and phenol and the smell scores of the textile cannot be judged by the content of one or several components in the textile. This study provides an effective basis for the further study of the formation mechanism and process of the third-hand smoke odor. Based on the experimental design and response surface theory we screen out the factors that have significant influence on the removal of cigarette smell from textiles and give the optimal combination of parameters. At the same time we analyze the components of cigarette smell adsorbed on cotton fabrics which can provide theoretical reference for the development and function optimization of textile deodorization products.

Objective To explore the related factors influencing vitamin D levels in breast cancer patients treated with AI. Methods By collecting information about breast cancer patients, the deficiency rates of 25 (OH) D3 was compared between using AI and not using AI breast cancer patients. Vitamin D levels in patients using AI was classified as sufficiency, insufficiency and deficiency, Univariate analysis and logistic regression model were used to explore the effects of age, menopause duration, AI duration, Use of anti-OP drugs and its type and duration on content of 25 (OH) D3 . Results The difference of vitamin D deficiency rate between using AI and not using AI breast cancer patients was statistically significant ( P < 0. 05). Logistic result showed that age, menopause duration and AI duration were the risk factors for vitamin D deficiency, and the use of anti-OP drug was its protective factor ( P

Aryl hydrocarbon receptor (AhR), with an important immunoregulatory mechanism underlying immunosuppression, tolerance, and immunity, is a member of a basic helix-loop-helix family and it exists in cytoplasm and normally inactive. Many AhR-mediated immunoregulatory mechanisms have been discovered. It has significant biological functions in inhibiting tumor development and inflammation when binding with its corresponding endogenous ligands and causing changes in the gene transcription subsequently. So, it is important to discuss the molecular mechanisms of AhR activated by endogenous ligands and the role of AhR in tumor treatment and regulation of anti-inflammatory response. In this paper, the type, function and clinical application of AhR endogenous ligands was introduced and research prospect was presented. [ABSTRACT FROM AUTHOR]

In order to ease the congestion of macro traffic network and reduce the fuel consumption of vehicles, the equilibrium equations of the traffic flow in the congested area are established based on subregions classified by macroscopic fundamental diagram (MFD) according to different network state. Then the road network is divided into two categories, such as intersection and road section and a network energy consumption estimation model is established according to the parameter of MFD. Dual objective optimal control model of the congestion area boundary is built up with the goal of lowest energy consumption and the highest travel completion rate of vehicles in macro network. Finally, the actual city road network is used as the test object. By comparing the control scheme of the no boundary control, Bang-Bang entrance boundary control and dual objective optimal control scheme, the following conclusions are got: 1) At the peak time, the network evacuation capability under the dual objective optimal control is improved by 20.14% and 2.1% compared With the no boundary control and Bang-Bang entrance boundary control at the same time, vehicle fuel consumption decreased by 43.14% and 24.48% respectively. 2) Dual objective optimal control method can effectively improve the traffic density equilibrium inside and outside the congested area. 3) The boundary control of the congested area in macro network can effectively reduce the congestion level during rush hour and improve the evacuation ability of the whole network.
