Objective To determine the level of awareness of the hazards of tobacco smoking and secondhand smoke inhalation among adults in China. Methods Household surveys were conducted with a total of 13 354 respondents aged 15 years or over from 100 counties of 28 Chinese provinces using a stratified multi-stage geographically clustered sample design. Results The findings revealed that 81.8% of the population was aware that smoking causes serious diseases, and 27.2% and 38.7% were aware that smoking causes stroke and heart attack, respectively. Only 64.3% of respondents were aware that secondhand smoke can cause serious diseases, and 27.5%, 51.0%, and 52.6% were aware that secondhand smoke causes heart disease in adults, lung disease in children and lung cancer in adults, respectively. Awareness regarding smoking-related hazards across all participants was significantly associated with several factors, including gender, smoking status, urban/rural residency, education level and exposure to tobacco control publicity in the last 30 days. Awareness regarding tobacco-related hazards in smokers was significantly associated with urban/rural residency, education level, exposure to tobacco control publicity in the last 30 days, and physician＇s advice. Awareness relating to the hazards of inhaling secondhand smoke was associated with smoking status, urban/rural residency, age, education level, and exposure to tobacco control publicity in the last 30 days. Medical professionals were found to know more about the health hazards of tobacco compared with people in other types of employment. Conclusions Overall awareness of the health hazards of tobacco has improved in the last 15 years in China, but is still relatively poor. Improved means of communicating information and more effective warning labels on cigarette packaging are necessary for increasing public awareness of tobacco hazards, particularly among rural residents and people with less education.

With the rapid development of economy, industrial and agricultural pollutants have caused great damage to the ecological environment and the normal development of organisms, posing a serious threat to global public health. Therefore, rapid and sensitive detection of pollutants is very important for environmental safety and people’s health. A stable multi-response fluorescence sensor(RhB@1) with dual emission characteristics was constructed by embedding Rh B guest molecules in Zn-MOF using a simple one-pot method. XRD, IR, XPS, Raman and other characterization methods were used to demonstrate the formation of composite materials. The sensor has two fluorescence emission peaks at 415 nm and 575nm under the excitation of 316 nm. It has high sensitivity and low detection limit(7.94 and 7.82 nmol/L,respectively) in the detection of fluazinam(FLU) and Fe^(3+). The mechanism of fluorescence quenching may be due to the synergistic effect of IFE and PET. Outstandingly, when ascorbate acid(AA) was added to the quenching system of Fe^(3+) and Rh B@1, its fluorescence gradually recovered, forming the unique“on-off-on” sensor. Therefore, RhB@1 has a fast fluorescence response and good stability, making it potentially useful in practical application and biosensors. More significantly, using Fe^(3+)and AA as chemical input signals, a binary intelligent logic gate device has been developed based on the “on-off-on” response mode of RhB@1, which extends the application of logic gate switching devices in the chemical field. In addition, a visual portable test paper with good selectivity and high sensitivity was developed, which can be used for rapid detection of FLU, showing its broad application prospect.

Aim:To test the effect of orexin-A(hypocretin-1),a neuropeptide synthesized inthe lateral hypothalamus and the perifornical area,on the glycinergic inputs andthe GABAergic inputs of cardiac vagal neurons(CVN).Methods:The effects oforexin-A at three concentrations(20 nmol/L,100 nmol/L,500 nmol/L)on theglycinergic inputs and the GABAergic inputs were investigated by using retro-grade fluorescent labeling of cardiac neurons(CVN)in the nucleus ambiguus(NA)and the voltage patch-clamp ***:Orexin-A dose-depen-dently increased the frequency of both the glycinergic and the GABAergic spon-taneous inhibitory postsynaptic currents(sIPSC).However,at a lower concentra-tion(20 nmol/L)of orexin-A,although the frequency of the glycinergic sIPSC wassignificantly increased,the frequency of the GABAergic sIPSC was not signifi-cantly ***:The glycinergic inputs and the GABAergic inputshave different sensitivities to orexin-A,which suggests that the two kinds ofinhibitory inputs might play different roles in the synaptic control of cardiac vagalfunctions.

为研究沥青混合料的砂浆厚度组成规律,考虑集料间接触的最薄弱方向,提出了一种基于最短接触距离原则的沥青混合料砂浆厚度计算方法。采用高精度二维扫描仪获取混合料二维切片图像,定义沥青砂浆由沥青以及粒径小于等于1.18mm的细集料组成,并利用MATLAB相关图像处理方法进行混合料砂浆空间结构分析。提出平均砂浆厚度、砂浆厚度谱的众数及集中度指标,并对其进行统计分析。针对6种不同类型的混合料,研究不同压实次数、沥青种类、最大公称粒径以及级配类型等因素对其砂浆厚度的影响。结果表明:提出的方法适用于分析沥青混合料的砂浆厚度组成规律;砂浆厚度谱用对数正态分布模型进行拟合的效果较好;随着压实次数的增加,平均砂浆厚度及厚度谱众数均存在最小值,而砂浆集中度则存在峰值,说明过压会破坏砂浆的稳定状态,合理选择压实次数十分重要;较小的集料最大公称粒径、悬浮密实型结构以及改性沥青混合料对应的平均砂浆厚度更小,砂浆也向更小的厚度上集中,其集中度更高;级配类型和最大公称粒径的影响最为显著,沥青种类对厚度谱的集中度也有较为显著的影响,压实次数的影响虽然不大但也呈现出明显的规律性。

沥青混合料自愈合行为与沥青砂浆的细观分布特征关系密切,但目前相关判据不足。为此,采用数字图像处理技术定量表征沥青砂浆的细观结构,并分析其与混合料自愈合行为的关系。首先,优化沥青混合料砂浆厚度计算的方法,提出基于图像分析的砂浆平均厚度Tm和砂浆厚度分布标准偏差SDt指标;其次,对6种不同沥青混合料砂浆的二维图像进行统计分析,验证细观砂浆厚度参数的有效性;最后,通过有无间歇时间的半圆弯曲疲劳试验获取沥青混合料的自愈合指数H,并进行宏细观指标的相关性分析。结果表明:级配类型和最大公称粒径均对沥青砂浆的空间分布有重要影响;矿料间隙率(VMA)和沥青饱和度(VFA)与砂浆细观参数之间不存在明显相关关系,证实了宏观体积参数在表征沥青砂浆细观分布特征方面的不足;沥青混合料的自愈合指数同时受砂浆平均厚度和空间分布均匀性的影响;综合指标Tm/SDt与宏观愈合指数H之间有很好的相关性,可以有效表征沥青混合料的自愈合效率。
