In addition to common clinical features, patients with coronavirus disease 2019 (COVID-19) have varying degree of coagulation dysfunction with the risk of thrombosis and/or bleeding. COVID-19 related coagulation dysfunction is a dynamic process, which may be accompanied by the formation of disseminated intravascular coagulation and is related to the severity of the disease. The imbalance of the body's immune and inflammatory response caused by coronavirus infection is an important cause of coagulation dysfunction. Dynamic monitoring as well as early prevention and treatment are of great significance for improving the prognosis of patients. This article reviews the research progress of COVID-19 related coagulation dysfunction, to provide reference for clinical research and management.

The coronavirus disease 2019 (COVID-19) has caused a global pandemic. All people including children are generally susceptible to COVID-19, but the condition is relatively mild for children. The diagnosis of COVID-19 is largely based on the epidemiological evidence and clinical manifestations, and confirmed by positive detection of virus nucleic acid in respiratory samples. The main symptoms of COVID-19 in children are fever and cough; the total number of white blood cell count is usually normal or decreased; the chest imaging is characterized by interstitial pneumonia, which is similar to other respiratory virus infections and infections. Early identification, early isolation, early diagnosis and early treatment are important for clinical management. The treatment of mild or moderate type of child COVID-19 is mainly symptomatic. For severe and critical ill cases, the oxygen therapy, antiviral drugs, antibacterial drugs, glucocorticoids, mechanical ventilation or even extracorporeal membrane oxygenation (ECMO) may be adopted, and the treatment plan should be adjusted timely through multi-disciplinary cooperation.

OBJECTIVETo recognize the clinical features of the bronchiolitis obliterans.

METHODClinical manifestation, chest X-ray, computed tomography (CT) and pulmonary function of 4 cases with bronchiolitis obliterans were retrospectively analyzed.

RESULTTwo cases were after Stevens-Johnson syndrome (SJS), the other 2 were after severe pneumonia, including one suffered from adenovirus pneumonia. Cough, tachypnea and wheezing persisted in all the 4 patients. The symptoms lasted for at least 6 weeks, in one case for over one year. Crackles and wheezing were present in all the 4 cases. Hyperinflation was seen in chest radiographs in all cases. On pulmonary CT/high-resolution CT (HRCT), patchy opacity and bronchial wall thickening were seen in each patient. Areas of air trapping were seen in three cases. Bronchiectasis was seen in 2 cases, atelectasis and mosaic perfusion were seen respectively in one case. PO(2) was low in all the four cases. Wheezing was not responsive to beta(2) agonist and other bronchodilating therapy. Prednisone was used at a dose of 1 mg/(kg.d) in 3 cases. Two cases were followed up for 3 months. The clinical condition of one case was improved, whose wheezing and bronchiolar constriction disappeared, cough and dyspnea were also relieved. However, the condition of one patient was not improved, although the wheezing disappeared. The HRCT of these two cases showed no improvement.

CONCLUSIONClinical symptoms of BO were cough, tachypnea, and wheezing after acute lung injury. Crackles and wheezing were the most common signs in the BO. Chest radiographs showed hyperinflation. Pulmonary CT showed bronchial wall thickening, bronchiectasis, atelectasis, and mosaic perfusion. Pulmonary function tests suggested obstruction of small airway.

OBJECTIVE: To explore the risk factors of anxiety and depression in patients with suspected coronavirus disease 2019 (COVID-19) so as to achieve early intervention and better clinical prognosis. METHODS: Seventy-six patients with suspected COVID-19 in fever isolation wards of Second Hospital of Lanzhou University were enrolled From January 31, 2020 to February 22, 2020. Their clinical baseline data were collected. The anxiety of patients was assessed by Hamilton Anxiety Scale, and the depression of patients was assessed by Hamilton Depression Scale. Multivariate Logistic regression analysis was performed to explore the risk factors of anxiety and depression in these patients. RESULTS: Female patients are more likely to have anxiety (=3.206, 95%: 1.073-9.583, <0.05) and depression (=9.111, 95%: 2.143-38.729, <0.01) than male patients; patients with known contact history of epidemic area and personnel in epidemic area are more likely to have depression (=3.267, 95%: 1.082-9.597, <0.05). CONCLUSIONS During the isolation treatment of suspected COVID-19 patients, early psychological intervention should be carried out for the female patients with known contact history of epidemic area and personnel in epidemic area, and drug treatment should be given in advance if necessary.

Since the outbreak of novel coronavirus pneumonia (coronavirus disease 2019, COVID-19), it has rapidly spread to 187 countries, causing serious harm to the health of people and a huge social burden. However, currently, drugs specifically approved for clinical use are not available, except for vaccines against COVID-19 that are being evaluated. Traditional Chinese medicine (TCM) is capable of performing syndrome differentiation and treatment according to the clinical manifestations of patients, and has a better ability of epidemic prevention and control. The authors comprehensively analyzed the etiology and pathogenesis of COVID-19 based on the theory of TCM, and discussed its syndrome differentiation, treatment and prevention measures so as to provide strategies and reference for the prevention and treatment with TCM.

OBJECTIVETo compare the clinical features and co-infection between pneumonia caused by influenza virus A (IVA) and pneumonia caused by influenza virus B (IVB) among children.

METHODSA total of 165 children with pneumonia caused by influenza virus (IV) were included in the study. These subjects were divided into IVA(n=71) and IVB pneumonia groups (n=94) according to the subtypes of IV. The IVA pneumonia group was further divided into simple infection (n=14) and co-infection subgroups (n=57), and the IVB pneumonia group was also further divided into simple infection (n=27) and co-infection subgroups (n=67). Co-infection rate and pathogen spectrum were analysed in children with IV pneumonia.

RESULTSThe IVB pneumonia group had significantly increased mean age of onset and significantly prolonged mean duration of fever compared with the IVA pneumonia group (P<0.05). Co-infection rate among children with IV pneumonia was 75.2%, who were co-infected with bacteria (44.2%), Mycoplasma pneumoniae (MP, 21.8%) and other viruses (45.5%). Respiratory syncytial virus (RSV) was most common in children co-infected viruses (89% ). The rate of co-infection with RSV was significantly higher in the IVA pneumonia group than in the IVB pneumonia group. There were no significant differences in age, length of hospital stay, duration of fever, percentage of neutrophils, prealbumin, C-reactive protein, alanine aminotransferase, and creatine kinase-MB between the simple infection and co-infection subgroups of each group.

CONCLUSIONSChildren with IVB pneumonia have prolonged duration of fever and increased age of onset compared with those with IVA pneumonia. Co-infection rate is high among children with IV pneumonia, who may be co-infected with bacteria, viruses and MP. Co-infection with RSV is more common in children with IVA pneumonia. It is difficult to identify the presense of co-infection using clinical indices.
