Role of mental health professionals in dealing with the stigma attached to COVID-19

The stigma associated with the disease may be as subtle as avoidance,or dramatic as physical aggression.COVID-19 has begun to cause social disruption by growing disease-related stigma and xenophobia against some cultural,national,racial or religious groups worldwide.1 People of East Asian origin and those with facial features like them,or those with a travel history to areas affected by the outbreak,are especially being subjected to xenophobia in personal contact and online threats.COVID-19 has arisen as an unknown and newly emerged highly contagious infection that has spread rapidly across the globe and is associated with high mortality,leading to fear of encountering those infected.2 Leaders across the world have taken strict measures such as lockdowns and shutdown of various vital services that have caused chaos in people’s lives and increased concerns about the disease.3 Box 1 lists the factors leading to stigmatisation towards those infected with COVID-19.

Dealing with Asymmetrical Abel Inversion Using Fourier-Bessel Expansions

A new method is presented for dealing with asymmetrical Abel inversion in this paper.We separate the integrated quantity into odd and even parts using Yasutomo's method. The asymmetric local value is expressed as the product of a weight function and a symmetric local value. The symmetric distribution is expanded into Fourier-Bessel series. The coefficients of the series are determined by the use of a least-square-fitting method.

Effects of Probability of Accurately Predicting and Ascertaining Defection on Cooperation and its Application to Simulated Internet Dealing

Without cooperative behaviors, our society or organization falls into social dilemma situations where every member selects uncooperative （defective） behaviors, and the situation gets worse and worse. Such a situation in a society or an organization leads to violation of social or organizational rules, and at the worst case it suffers from serious accidents or scandals. Therefore, it is important for us to make efforts and take measures to elicit cooperative behaviors. It was demonstrated theoretically that altruism strategy and adaptive prediction and ascertainment strategy are in some cases better than rational strategy under the situation of social dilemma. We built up a mathematical model in order to examine how the probability of correctly predicting and ascertaining the behavior （cooperation or defection） of opponents and the mixture of （a） altruism （all cooperation） strategy, （b） individualism （all defection） strategy, and （c） adaptive prediction and ascertainment strategy affected the expected profit. Simulation results showed that the tit-for-tat strategy was better than the rational （individualism） strategy when the probability of correctly predicting and ascertaining defection of the opponent was considerably higher. As an application of the basic study above, it was explored, using a simulation method, how such a system as opening reputation or peer review in public could work satisfactorily to prevent defective behaviors in auction dealing. The result showed that the information on the handle name and the reputation effectively worked to prevent defective behaviors.

Chinese expert consensus on the clinical application of drugcoated balloon(2^(nd) Edition)

Percutaneous coronary interventions have progressed through the era of plain balloon dilation, bare-metal stent insertion to drug-eluting stent treatment, which has significantly reduced the acute occlusion and restenosis rates of target vessels and improved patient prognosis, making drug-eluting stents the mainstream interventional treatment for coronary artery disease. In recent years, drug-coated balloons(DCBs) have become a new treatment strategy for coronary artery disease, and the drugs used in the coating and the coating technology have progressed in the past years. Without permanent implant, a DCB delivers antiproliferative drugs rapidly and uniformly into the vessel wall via the excipient during a single balloon dilation. Many evidence suggests that DCB angioplasty is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary vessels.As more clinical studies are published, new evidence is emerging for the use of DCB angioplasty in a wide range of coronary diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary de novo lesions, and precise guidance of DCB treatment by intravascular imaging and functional evaluation.

Fish-on-Chips:unveiling neural processing of chemicals in small animals through precise fluidic control

Precise chemical cue presentation alongside advanced brainwide imaging techniques is important to the study of chemosensory processing in animals.Nevertheless,the dynamic nature of chemical-carrying media,such as water or air,poses a significant challenge for delivering highly-controlled chemical flow to an animal subject.Moreover,contact-based cue manipulation and delivery easily shift the position of the animal subject,which is often undesirable for high-quality brain imaging.Additionally,more advanced interfacing tools that align with the diverse range of body part sizes of an animal,ranging from micrometer-scale neurons to meter-long limbs,are much needed.This is particularly crucial when dealing with dimensions that are beyond the reach of conventional experimental tools.

Controversial protamine in dealing with acute cardiac tamponade during radiofrequency ablation

To the Editor:During radiofrequency catheter ablation(RFCA),acute cardiac tamponade is a common but life-threatening occurrence in which rapid blood accumulation in the pericardium cavity compresses the heart and causes the systemic circulation to deteriorate.Emergency percutaneous pericardiocentesis and immediate autologous blood transfusion are necessary.The administration of protamine for incessant bleeding is controversial,for pericardial blood clots may form spontaneously despite the neutralizing effects of heparin and may even necessitate thoracotomy.Our aim is to discuss the necessity and optimum time of protamine administration and to explore the means to prevent blood clot formation.

AN EXAMINATION OF LEGAL REGULATIONS FOR INSIDER DEALING IN THE UK AND THE LESSONS FOR CHINA

The UK＇s position as a leading international financial center depends not only on the openness and competitiveness of its market, but also on its reputation as a clean and fair place to do business. Market confidence will be undermined where participants and users believe markets are susceptible to abuse. Thus, the main convincing justification for controlling insider＇s abuse of power is based on the harm principle, which it causes to investor confidence and securities markets. An insider ought not to be able to take advantage of his position either to breach a confidence or to achieve an unfair advantage in the market place; particularly the market place should, as far as possible, provide equality of opportunity to people entering it. Insider dealing has been regulated by the criminal law involved under Part V of the Criminal Justice Act 1993 in the UK. It has become clear that the traditional criminal penalty was limited by the criminal standard of proof required, while self-regulatory regimes are thought as toothless tigers. Although various potential common law civil remedies for breach of fiduciary duty and breach of confidence relating to insider dealing do exist, they are ineffective remedies and beset by so many complexities. As a response, the Financial Services and Markets Act 2000 came into force and marked an important development in the regulation of market abuse in creating civil penalties, which also contained misuse of confidential insider information. Later, the main substantive changes to existing civil market abuse regime have been taken effect within the Financial Services and Markets Act 2000 （Market Abuse） Regulations 2005, 2011 and 2014. Regarding to the regulatory framework, the range of regulatory powers of the Financial Services Authority, which has been replaced by the Financial Conduct Authority in April 1, 2013, available in combating market abuse is one of the most fundamental innovations of the FSMA 2000 and plays a significant role in defining the law in practice through a Code of Market Conduct. China has also exerted great efforts in regulating insider dealing. Under thecurrent Chinese legal framework, insider dealing is governed by the Criminal Law of the People＇s Republic of China, the Securities Law of the People＇s Republic of China 2005 and some other regulations. The China Securities Regulatory Commission （CSRC） is the regulatory body for supervising and penalizing insider dealing in China. Although China has made progress in legislation in terms of the regulation of insider dealing, there are still much room for improvement, such as the enforcement of the civil penalty and the enforcement power of the CSRC. Due to the fact that the UK has rich experience in regulating insider dealing, it is of great significance for China to learn from the UK＇s successful practices. Insider dealing could be well controlled with innovative and effective legal regulations. This article focuses on an in-depth examination on the regulations in the UK and a brief introduction of regulations in China in order to figure out an answer to what has been achieved in the UK and what are the most important aspects that China could learn from the UK＇s experiences. The aim of increasing the deterrent effect by reducing the obstacles to imposing suitable sanctions, whether criminal, civil or regulatory, should enable regulators to police a more efficient manner in the field of financial markets.
