If one word is used to describe the development of congenital heart disease surgery in China, "hardship" would be the most appropriate. Generations of pioneers have used their ingenuity to overcome obstacles and promoted the development of the discipline. Seventy years of efforts have established the world's largest congenital heart disease treatment system. However, the huge number of potential patients, low early diagnosis rate and over-screening as well as the uneven developed diagnosis and treatment capabilities hinder the future development. The overall improvement of treatment of congenital heart disease in China lies on more efforts from our fellow experts. The publication of the "Chinese expert consensus on surgical treatment of congenital heart diseases" undoubtedly provides theoretical and practical guidance for the improvement of treatment.
Motor imagery (MI) is an important paradigm of driving brain computer interface (BCI). However, MI is not easy to control or acquire, and the performance of MI-BCI depends heavily on the performance of the subjects’ MI. Therefore, the correct execution of MI mental activities, ability evaluation and improvement methods play important and even critical roles in the improvement and application of MI-BCI system’s performance. However, in the research and development of MI-BCI, the existing researches mainly focus on the decoding algorithm of MI, but do not pay enough attention to the above three aspects of MI mental activities. In this paper, these problems of MI-BCI are discussed in detail, and it is pointed out that the subjects tend to use visual motor imagery as kinesthetic motor imagery. In the future, we need to develop some objective, quantitatively visualized MI ability evaluation methods, and develop some effective and less time-consumption training methods to improve MI ability. It is also necessary to solve the differences and commonness of MI problems between and within individuals and MI-BCI illiteracy to a certain extent.
ObjectiveTo explore ways so as to improve smoking cessation rates by studying relevant cases in Hong Kong.MethodsPatients attending the clinical pilot project in Hong Kong from 2010 to 2022 were retrospectively surveyed and analyzed. Information such as patients' general information, reasons for smoking for the first time, situations that enable smoking, barriers to smoking cessation, and withdrawal symptoms were obtained using a pre-designed case report form and analyzed.ResultsA total of 10436 patients, 6936 males and 3500 females, were included. Influenced by friends (67.70%), relieving mental stress (33.12%) and curiosity (30.52%) were the main reasons for smoking for the first time; depression (57.14%), after meals (49.08%) and nervousness (41.26%) were the situations that enable smoking; the main barriers to smoking cessation were physiologic dependence (87.06%) friends or colleagues smoking (37.03%) and compulsiveness to use tobacco (32.45%), top withdrawal symptoms smoking stoppage were craving for cigarettes (50.33%), restlessness (38.33%), and difficulty concentrating (26.63%).ConclusionsThe proportion of patients actively choosing to quit smoking is high in Hong Kong, and smoking cessation methods should be publicized to prompt smokers to take effective measures to quit. A majority of people are influenced by friends to smoke for the first time; thus, adolescent smoking behavior should be supervised to reduce first-time smokers. Moreover, as the most difficult thing to overcome in the process of quitting smoking is psychological addiction, behavioral interventions must be promoted to improve the rate of successful quitting, Steps should be taken to enable the management of withdrawal symptoms to prevent relapse.
