RESUMO

The outbreak of coronavirus disease 2019 (COVID-19) in Dec. 2019 sounded another alarm for humanbeing, with the first being the outbreak of severe acute respiratory syndrome (SARS) in 2003. Researchers found that the natural host of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen of COVID-19, may be the Rhinolophus sinicus. There have been four outbreaks of coronaviruses (severe acute respiratory syndrome coronavirus [SARS-CoV], Middle East respiratory syndrome coronavirus [MERS-CoV], swine acute diarrhea syndrome coronavirus [SADS-CoV] and SARS-CoV-2) worldwide since the beginning of 21st century, and they have caused huge threats and losses to human health, public health, economic development, and social stability. A large amount of evidence suggests that the natural host of all these four coronaviruses may be bats. This article reviews the species and global geographic distribution of bat-related coronaviruses, and the above-metioned four coronaviruses causing severe outbreaks.

RESUMO

<p><b>OBJECTIVE</b>To investigate the main inhalant allergens and their distribution patterns in children with allergic diseases from Xi'an and the surrounding area and to provide evidence for the prevention and treatment of allergic diseases in children.</p><p><b>METHODS</b>Skin prick test was performed using liquid with 13 standardized allergens (ALK-ABELL, Denmark) on 3085 children from Xi'an and the surrounding area who were treated for allergic diseases between July 2006 and July 2011, to detect inhalant allergens.</p><p><b>RESULTS</b>Of the 3085 patients, 1368 (44.34%) had positive SPT results, with the most prevalent inhalant allergen being Dermatophagoides pteronyssinus (804 cases, 26.06%), followed by Dermatophagoides farinae (793 cases, 25.71%), Blomia tropicalis (440 cases, 14.26%), mugwort (282 cases, 9.14%), and cat hair (204 cases, 6.61%). The positive rates were 28.66% in the <4 years group, 41.85% in the 4-6 years group, and 58.61% in the 7-15 years group (P<0.01). Males had a significantly higher SPT positive rate than females (47.78% vs 38.50%;P<0.05). The SPT positive rate was highest in children with allergic rhinitis (72.41%), followed by bronchial asthma (62-25%), allergic dermatosis (45.83%), and allergic purpura (36.28%).</p><p><b>CONCLUSIONS</b>In children from Xi'an and the surrounding area, the main inhalant allergens for allergic diseases include Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis, mugwort and cat hair. The SPT positive rate increases with age. Male children have a higher SPT positive rate than female children. The SPT positive rate is highest in children with allergic rhinitis.</p>

RESUMO

Objective To explore the changes serum S-100? in children with acute carbon monoxide poisoning and its clinical significance.Methods The levels of serum S-100? of 28 children with acute carbon monoxide poisoning and those of 20 healthy children were mea-sured by enzyme-linked immunosorbent assay.Results The serum S-100? levels of the study group and control group were(0.517?0.346)and(0.037?0.014)?g/L respectively,there was significant difference between two groups(t=6.197 P
