Background: The use of mobile phone significantly improved the outcomes of tobacco cessation. However, its feasibility and acceptability were unclear in the Chinese population. This study was to explore the feasibility of using Wi-Fi access points (APs) as a platform to provide smoking cessation help at 17 airports and 38 railway stations across China. Methods: This study was divided into two stages: platform development and population survey. In the first stage, a survey platform was developed and incorporated into Wi-Fi service at airports and railway stations, which could provide survey content as a pop-up window when participants tried to access the Wi-Fi service. In the second stage, a population survey was conducted to explore the intention to receive tobacco cessation support. Results: A total of 20,199 users participated and 13,628 users submitted the survey, with a response rate of 67.47%. The smoking rate was 30.9%. A total of 86.58% of smoking participants and 2.44% of non-smoking participants wished to receive tobacco cessation support, respectively. The multivariate analysis showed intention to receive support did not differ in age, gender, and heaviness of smoking (P > 0.05). Conclusion: Providing tobacco cessation support via Wi-Fi APs is feasible and efficient, and smokers have high intention to receive tobacco cessation support. It is suggested hospitals, academia, information technology industries, and government agencies must work together to provide tobacco cessation support via mHealth.

Objective:To observe the differences of clinical efficacy of intractable lumbodynia after lumbar disc herniation surgery treated by pestle needling at Yāoyángguān Bāzhèn points,electroacupuncture and western medication.Methods:A total of 210 patients with intractable lumbodynia after lumbar disc herniation were randomly divided into pestle needle group,electroacupuncture group and western medication group,with 70 cases in each group.The pestle needle group was treated with pestle needle poking Yāoyángguān-Bāzhèn(GV3-Bāzhèn)points.The electroacupuncture group was treated with conventional electroacupuncture,and the western medication group was treated with oral diclofenac sodium dual release enteric-coated capsules(Difene).The pestle needle group and the electroacupuncture group were treated once a day,and there was 1 day of rest after 6 days of treatment,and a course of treatment included 7 days,and a total of 3 courses of treatment were performed.The western medication group took 1 Difene capsule(75 mg)at a time,with once a day continuing for 21 days.Visual Analog Scale(VAS),Pain Rating Index(PRI)and Present Pain Intensity(PPI)were used to observe the improvement of pain before and after treatment,and the waist muscle tone was examined and the clinical efficacy was observed.Results:The post-treatment VAS,PRI,and PPI scores of the three groups were all lower than pretreatment,and the differences were statistically significant(all P0.05).Meanwhile,they were all lower than the electroacupuncture group,and the differences were statistically significant(both P<0.05).After treatment,the waist muscle tone of the three groups was higher than that pre-treatment,and the differences were statistically significant(all P<0.05).After treatment,the waist muscle tone of the pestle needle group was higher than the electroacupuncture group,and the electroacupuncture group was higher t

Focusing on the effect specificity of meridian points along the running course of meridian,by taking the treatment of post-stroke depression(PSD)with the acupoints of the governor vessel as an example,the correlation between meridian points and disease was explored.The specific regulatory effect of governor vessel,Baihui(百会GV20)and Shenting(神庭GV24)in physiology and pathology in PSD and the material basis of the specificity effect were analyzed.Finally,the specific relationship between the acupoints of the governor vessel and PSD was explained.

Singularities in the spectra of open systems, known as exceptional points(EPs), have been shown to exhibit nontrivial topological properties and enhanced sensitivities. Here, we propose a novel approach to realize the EPs in a plasmon-exciton hybrid system and explore their applications in enhanced nanoscale sensing technology.We consider a plasmon-exciton system composed of a gold nanorod and a monolayer WSe_(2). By controlling the geometric parameters of the nano-hybrid system, we obtain simultaneous coalescence of the resonance frequencies and loss rates of the hybrid system, which is a unique feature of EPs. Numerical simulations show its application in enhanced nanoscale sensing for environmental refractive indices. Our work opens the way to a new class of sensors based on EP-enhanced sensing, with intrinsic nanoscale sensitivity due to the sub-diffractionlimit size of the plasmon-exciton nano-hybrid system.

Objective:To observe the clinical therapeutic effects on nervous olfactory disorder treated with acupuncture at three nasal points and scalp acupuncture.Methods:Acupuncture was applied in 30 eligible patients with nervous olfactory disorder.The points included three nasal points,i.e.,Yíngxiāng(迎香 LI 20),Shàngyíngxiāng(上迎香 EX-HN 8)and Yìntáng(印堂EX-HN 3),ézhōngxiàn(额中线 middle line of forehead,MS1)and bilateral Nièhòuxiàn(颖后线 posterior temporal line,MS11).The even-needling technique was used to stimulate the three nasal points to ensure deqi. In scalp acupuncture,the needle was rotated continuously at 200 times per min,for 2 min at each scalp acupuncture line.The needles were retained for 40 min at above points and lines and were manipulated once every 20 min during needle retaining.The treatment was given once a day,6-day treatment was as one course and the next course of treatment started after the interval of 1 day.Totally,4 courses of treatment were required.Before and after treatment,T&T olfactory was adopted to test the olfactory function and the score was compared in order to evaluate the therapeutic effect.Results:Of 30 cases,8 cases were cured,20 cases remarkably effective and 2 cases failed.The total effective rate was 93%.Conclusion:Acupuncture at three nasal points and scalp acupuncture are effective approach to nervous olfactory disorder.

Let K be a normal subgroup of the finite group H. To a point of a K-interior H-algebra we associate a group extension, and we prove that this extension is isomorphic to an extension associated to the point given by the Brauer homomorphism. This may be regarded as a generalization and an alternative treatment of Dade＇s results [2, Section 12].

传统的人工蜂群算法(Artificial Bee Colony algorithm,ABC)及其在多目标上的扩展(Multi Objective Artificial Bee Colony algorithm,MOABC)存在着在高维、多峰函数情况下收敛速度变慢、后期容易陷入局部最优以及寻优精度丢失等问题。基于knee points提高收敛性和分布性的特点,设计了一种快速识别knee point的算法并将其应用到多目标人工蜂群算法中,提出了一种基于knee points的改进多目标人工蜂群算法(Kn MOABC)。算法在迭代过程中考虑pareto支配关系的同时,优先选择knee point作为下一代个体,极大地增强了算法的收敛速度,同时,在knee point识别算法中加入自适应的策略以保持良好的分布性。实验结果表明,Kn MOABC的性能优于三个最新的多目标人工蜂群对比算法。

Sharkovskii proved that, for continuous maps on intervals, the existence of 3-cycle implies the existence of all others. Li and Yorke proved that 3-cycle implies chaos. To establish a domain of uncountable cycles in the logistic map and to understand chaos in it, the fixed points of 3-cycle are obtained analytically by solving a sextic equation. At one parametric value, a fixed-point spectrum, resulted from the Sharkovskii limit, helps to realize chaos in the sense of Li and Yorke.
