The outbreak of Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged and spread rapidly throughout the world. As of February 29, 2020, 79 389 cases of COVID-19 have been reported, and the outbreak is linked to 2838 deaths. The population is generally susceptible to the disease, and differences in incubation periods after infection exist among individuals. These two aspects of COVID-19 pose significant challenges to pediatric orthopedic diagnosis and treatment. As a dedicated center for managing pediatric cases of SARS-CoV-2 in Shanghai, our hospital has mobilized all branches and departments to undertake joint actions for scientific prevention and control, precise countermeasure and comprehensive anti-epidemic efforts. Combined with our experience, we have consulted the relevant national regulations and the latest research advances and have formulated the prevention and control measures of SARS-CoV-2 infection, including outpatient, emergency, inpatient and surgical cares, for clinical practices of pediatric orthopedics according to the physicochemical properties of SARS-CoV-2. It may serve as practical references and recommendations for managing SARS-CoV-2 infection in other pediatric specialties and in other hospitals.

The work demonstrates the synthesis and biological evaluation of a new series of isoxazol-4-carboxa piperidyl derivatives.

In this study, we prepared three different silicon quantum dots (SiQDs-1, SiQDs-2 and SiQDs-3) by hydrothermal synthesis with rose Bengal as the reducing agent and triacetoxy(methyl)silane and allyloxytrimethylsilane as silicon sources.

In this study, a new series of tetrahydrobenzothiophene derivatives have been designed.

A vegetarian diet is a type of diet that excludes meats, or seafoods, or sometimes even eggs and dairy. People choose to have a plant-based diet like that are called vegetarians, and some of them do so for the purpose of preventing and treating disease. Because of the higher intake of vegetables, grains, fruit, nuts and fiber from a vegetarian diet and lower intake of saturated fat and cholesterol, a vegetarian diet has health benefits in lowering the risks of getting chronic disease like obesity, cardiovascular disease, and maybe even cancer. However, some people believe that eating a plant-based diet might cause an increased risk of deficiency of certain nutrients. The evidence available suggests that through carefully planning their diets and eating fortified food or supplement regularly, vegeterians can certainly be able to meet their nutrition needs. In order to give people who are considering to become a vegetarian some information about the health benefits and suggestions of having a plant-based diet, in this article, we carefully describe and analyze the relationships between vegetarian diets and BMI, obesity, and cardiovascular disease, and then the relationship between vegetarian diets and mortality from the commonest causes of death and cancer.
