Abstract： Severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19) shared similar pathogenetic, clinical and pathological features. Fever and cough were the most common symptoms of both diseases, while myalgia and diarrhea were less common in patients with COVID-19. Acute respiratory distress syndrome (ARDS) was the most severe pulmonary complication that caused high mortality rate. Histologically, diffuse alveolar damage (DAD) was the most characteristic finding in non-survivors with either SARS or COVID-19. Cases of patients died less than 10~14 days of disease duration demonstrated acute-phase DAD, while cases beyond 10~14 days of disease duration exhibited organizing-phase DAD in SARS. Meanwhile, organization and fibrosis were usually accompanied by exudation. Coronavirus was mostly detected in pneumocytes, while less in macrophages and bronchiolar epithelial cells. Hemorrhagic necrosis and lymphocytes depletion were found in lymph nodes and spleen in both SARS and COVID-19, indicating a pathological basis of lymphocytopenia. Thrombosis was commonly observed in small vessels and microvascular in lungs accompanying DAD. Microthrombosis was also found in extrapulmonary organs in COVID-19, that was less reported in SARS. Damages in multiple extrapulmonary organs were observed, but coronavirus was not detected in some of those organs, might indicating an alternative mechanism beyond viral infection, such as hypoxemia, ischemia and cytokine storm induced immunological injury. Diffuse alveolar damage due to viral infection and immunological injury, as well as multi-organ dysfunction and extensive microthrombus formation, brought huge challenge to the management of patients with severe SARS or COVID-19.

Abstract： Analysis of a case of an elderly patient visiting relatives from Wuhan to Shenzhen on January 19,2020 who was been diagnosed of COVID-19 and isolated after two visits on January 21 and January 29. According to the 'diagnostic and treatment options of the novel coronavirus pneumonia (trial version)' issued by National Health Commission of the People’s Republic of China on January 15, the patient can only be isolated at home because he did not met the diagnostic standard of 'suspected case' on January 21. But on January 21, the patient met the criteria and must be isolated in hospital according to the new 'diagnostic and treatment options of the novel coronavirus pneumonia (the 4th version)' issued on January 27 which .Therefore,it is suggested that during the outbreak of new infectious diseases, the diagnostic and treatment options should be revised quickly and reasonably for reducing the missed diagnosis and control the spread of infectious diseases.

Abstract： Objective To explore the relationships between medical coping modes of patients with COVID-2019 and general information and social supports. Methods From January to February 2020, a total of 128 patients in a designated hospital in Wuhan with novel coronavirus pneumonia were investigated using the General Information Questionnaire and the Chinese version of the Medical Coping Modes Questionnaire(MCMQ) by convenient sampling. Pearson univariate analysis and multiple linear regression were used to analyze the relationship between the basic situation of patients with novel coronavirus pneumonia and coping modes. Results The scores of the face dimension and yield dimension of patients with COVID-2019 were lower than the norm model, while the avoidance dimension was higher than the norm model, and the differences were statistically significant ( P <0.05). Support utilization and complexity were influencing factors of the face dimension ( P <0.05). Support utilization and age were influencing factors of the yielding dimension ( P <0.01). Subjective support, the complexity dimension of disease uncertainty and the number of confirmed patients in the family were influencing factors of the avoidance dimension ( P <0.01). Conclusions Patients with COVID-2019 have poor medical coping modes, and they are prone to face the disease with a negative attitude. Patients are unwilling to face the disease and the tendency to yield to the disease is greater. And the older the patients, the less likely they are to succumb to the disease. The more patients diagnosed in the family, the less likely they are to avoid the disease. Patients with higher social supports and utilization have a more reasonable medical coping mode. This reminds medical staff to pay more attention to the psychological problems of patients in coping with COVID-2019 and improve their coping modes and methods.

Abstract： We report a critically ill pregnant woman in the third trimester with severe pneumonia due to COVID-19 who presented to Xiaolan People's Hospital of Zhongshan in February 2020. The 32-year-old patient was admitted at 35 +2 gestational weeks with a 4-day history of a sore throat and a fever for three hours. The patient had been to Xiaogan City, Hubei Province, and the symptoms occurred during a period of self-isolation after back home. The condition of the patient deteriorated rapidly, with left-sided chest and back pain, shortness of breath, dizziness, progressing to respiratory failure and septic shock 7 hours after her admission. In view of her critical condition and a history of two previous cesarean sections, an emergency cesarean section was performed. Blood gas analysis of the mother before the operation suggested respiratory failure, respiratory acidosis, and metabolic acidosis. During the operation, a baby boy was born. The Apgar score of the boy, birth weight of 2 700 g, was one at 1, 5 and 10 minutes despite the resuscitation efforts. The neonate died after withdrawing treatment. The patient was treated with tracheal intubation ventilator and other supportive treatments after the operation. The result of the new coronavirus nucleic acid test, taken on admission, but which was reported after delivery, was positive. The patient was transferred to the designated hospital for further treatment and was recovering with the withdrawal of extracorporeal membrane oxygenation and ventilation support at 26 and 36 days after surgery, respectively.

Abstract： Objective To study the clinical application effect of modified nasopharyngeal swab sampling for 2019 novel coronavirus nucleic acid detection. Methods This study covered the period from January 14 to March 1, 2020. From February 24 on, the supine position method and the protective face screen were used to collect nasopharyngeal swabs, before which, the nasopharyngeal swabs were collected by sitting position method. All the patients were diagnosed with suspected/confirmed 2019 novel coronavirus infection, who were admitted from February 19 on, before which, the nasopharyngeal swabs were collected outside the hospital. (1) Thirty-four operators meeting the inclusion criteria of the study were recruited in this retrospective cohort study. They were grouped according to the collection method of nasopharyngeal swabs. Sixteen operators of Wuhan Taikang Tongji Hospital who used the supine position method and the protective face screen were included in supine position method+protective face screen group (15 males and 1 female, aged 34-49 years); 18 operators (12 from the First Affiliated Hospital of Army Medical University (the Third Military Medical University), 1 from Wuhan Jiangxia Mobile Cabin Hospital, 5 from the East District of People's Hospital of Wuhan University) who used the traditional sitting position method were included in sitting position method group (2 males and 16 females, aged 25-49 years). In supine position method+protective face screen group, when collecting sample, the patient lay flat and wore a special protective face screen for nasopharyngeal swab sampling, with neck slightly extending and face turning to the opposite side of the operator about 10°. The self-designed questionnaire was used to investigate the cooperation, the incidence of nausea, coughing, sneezing, and struggling of patients evaluated by the operators, the operation time of single sampling, the fear of operation and the perceived exposure risk of operators of the two groups. (2) Sixty-five patients (22 males and 43 females, aged 25-91 years) admitted to Wuhan Taikang Tongji Hospital who successively received the sitting position method and supine position method+protective face screen for nasopharyngeal swabs sampling and with complete nucleic acid detection results were included. The positive rates of nucleic acid detection by the two sampling methods of nasopharyngeal swabs of the patients were statistically analyzed. (3) Forty-one patients who could express their feelings accurately were selected from the above 65 patients (12 males and 29 females, aged 27-83 years). The comfort of patients in the process of sampling by the two methods was investigated. (4) Thirty-four patients (10 males and 24 females, aged 25-83 years) with two or more consecutive negative results of nucleic acid detection of nasopharyngeal swabs by sitting position method were selected from the above 65 patients. The positive rate of nucleic acid detection of nasopharyngeal swab of patients by supine position method+protective face screen, i.e. negative to positive rate was statistically analyzed. Data were statistically analyzed with Wilcoxon's sign rank test, t test, and chi-square test. Results (1) The cooperation score of patients evaluated by the operators in supine position method+protective face screen group was significantly higher than that in sitting position method group ( Z =-4.928, P <0.01), the incidence of nausea, choking cough, sneezing, and struggling of patients evaluated by the operators, and the fear of operation score and the perceived exposure risk score of operators were significantly lower than those of sitting position method group ( Z =-5.071, -5.046, -4.095, -4.397, -4.174, -5.049, P <0.01), and the operation time of single sampling was significantly longer than that of sitting position method group ( t =23.17, P <0.01). (2) The positive rate of nucleic acid detection of nasopharyngeal swabs by supine position method+protective face screen was 60.00% (39/65), which was obviously higher than 41.54% (27/65) by sitting position method ( χ 2 =4.432, P <0.05). (3) The comfort score of the 41 patients during nasopharyngeal swabs sampling by supine position method+protective face screen was significantly higher than that by sitting position method ( Z =-5.319, P <0.01). (4) Of the 34 patients with two or more consecutive negative results of nucleic acid detection of nasopharyngeal swabs by sitting position method, the rate of negative to positive of nucleic acid detection was 26.47% (9/34) after sampling by supine position method+protective face screen. Conclusions Compared with the traditional sitting position method, detection of 2019 novel coronavirus nucleic acids of nasopharyngeal swabs collected by supine method combined with protective face screen is worth promoting, because of its better comfort of patients, low exposure risk for operators, in addition to reducing in the false negative result to some extent, which may help reduce false recurrence of discharged patients.
