Analysis of chest imaging features of novel coronavirus pneumonia, bacterial pneumonia and viral pneumonia / 中华危重病急救医学

Objective:To investigate and summarize the chest CT imaging features of patients with novel coronavirus pneumonia (COVID-19), bacterial pneumonia and other viral pneumonia.Methods:Chest CT data of 102 patients with pulmonary infection due to different etiologies were retrospectively analyzed, including 36 patients with COVID-19 admitted to Hainan Provincial People's Hospital and the Second Affiliated Hospital of Hainan Medical University from December 2019 to March 2020, 16 patients with other viral pneumonia admitted to Hainan Provincial People's Hospital from January 2018 to February 2020, and 50 patients with bacterial pneumonia admitted to Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from April 2018 to May 2020. Two senior radiologists and two senior intensive care physicians were participated to evaluated the extent of lesions involvement and imaging features of the first chest CT after the onset of the disease.Results:Bilateral pulmonary lesions were more common in patients with COVID-19 and other viral pneumonia, and the incidence was significantly higher than that of bacterial pneumonia (91.6%, 75.0% vs. 26.0%, P < 0.05). Compared with other viral pneumonia and COVID-19, bacterial pneumonia was mainly characterized by single-lung and multi-lobed lesion (62.0% vs. 18.8%, 5.6%, P < 0.05), accompanied by pleural effusion and lymph node enlargement. The proportion of ground-glass opacity in the lung tissues of patients with COVID-19 was 97.2%, that of patients with other viral pneumonia was 56.2%, and that of patients with bacterial pneumonia was only 2.0% ( P < 0.05). The incidence rate of lung tissue consolidation (25.0%, 12.5%), air bronchial sign (13.9%, 6.2%) and pleural effusion (16.7%, 37.5%) in patients with COVID-19 and other viral pneumonia were significantly lower than those in patients with bacterial pneumonia (62.0%, 32.0%, 60.0%, all P < 0.05), paving stone sign (22.2%, 37.5%), fine mesh sign (38.9%, 31.2%), halo sign(11.1%, 25.0%), ground-glass opacity with interlobular septal thickening (30.6%, 37.5%), bilateral patchy pattern/rope shadow (80.6%, 50.0%) etc. were significantly higher than those of bacterial pneumonia (2.0%, 4.0%, 2.0%, 0%, 22.0%, all P < 0.05). The incidence of local patchy shadow in patients with COVID-19 was only 8.3%, significantly lower than that in patients with other viral pneumonia and bacterial pneumonia (8.3% vs. 68.8%, 50.0%, P < 0.05). There was no significant difference in the incidence of peripheral vascular shadow thickening in patients with COVID-19, other viral pneumonia and bacterial pneumonia (27.8%, 12.5%, 30.0%, P > 0.05). Conclusions:The probability of ground-glass opacity, paving stone and grid shadow in chest CT of patients with COVID-19 was significantly higher than those of bacterial pneumonia, and it was more common in the lower lungs and lateral dorsal segment. In other patients with viral pneumonia, ground-glass opacity was distributed in both upper and lower lungs. Bacterial pneumonia is usually characterized by single lung consolidation, distributed in lobules or large lobes and accompanied by pleural effusion.

All the collected data were further statistically analyzed by Chi-square test and rank sum test using SPSS 19.0Results:There were forty valid questionnaires and the participation rate was 100.0%. The accuracy of 24 NCP-related questions was not significantly different between residents majoring in ultrasound and other specialties [92.0%(596/648) vs. 93.6%(292/312), P>0.05]. All the residents had a good understanding of NCP. The main behaviors of going out were significantly reduced, while various behaviors of being at home were significantly increased. Their interest in learning declined. When the epidemic happened (or possibly) in the community or village they lived in, their negative emotions, such as nervousness, fear pessimism and depression, were obviously expressed. Network teaching and evaluation through WeChat public number were adopted and we guided residents to adjust their home behaviors and emotions according to the survey results. Conclusion:Under the NCP epidemic, the behaviors and emotions of residents had been extensively changed. The training center should adjust the teaching plan and mode of training in time, and provide more counselling service in psychology and learning for residents during the epidemic.

Fitting prediction of transmissibility and incidence trend of novel coronavirus pneumonia in Ningxia / 公共卫生与预防医学

Objective To analyze the change in transmissibility of novel coronavirus pneumonia and predict the trend of the incidence, and to provide a reference for the government to better respond to the novel coronavirus pneumonia epidemic. Methods The EpiEstimof R language software was used to estimate the change of effective basic reproduction number, and the Richards model was run by Matlab7.0 software to fit the cumulative number of confirmed cases and the number of suspected cases. The coefficient of determination and root mean squared error were used to evaluate the fitting effect of the model. Results A total of 75 confirmed cases and 107 suspected cases were reported in Ningxia. The strict implementation of various prevention and control measures gradually reduced the effective basic reproduction number from 3.82 to less than 1, indicating that the epidemic was under control. The Richards model was used to fit the cumulative confirmed cases and suspected cases, which revealed that the natural growth rates were 0.16 and 0.23, and the coefficients of determination were 0.991 and 0.998, respectively. Conclusion Combined with the effective basic reproduction number, the Richards model fitted the trend of novel coronavirus pneumonia, which can be used to predict the trend of incidence of new coronavirus pneumonia.

Detection and Analysis of Safety Signals of Chloroquine Based Upon FDA Adverse Event Database / 中国药学杂志

OBJECTIVE: To analyze and evaluate the safety signals of chloroquine in the patients, and to provide a valuable reference for rational use in clinic. METHODS: Both the reporting odds ratio (ROR) method and Bayesian confidence propagation neural network (BCPNN) were applied to analyze safety signals of chloroquine based upon the adverse drug events (ADEs) data ranging from 2004 to 2020 as reported in the Adverse Event Reporting System (FAERS) database of the Food and Drug Administration (FDA), and to systematically assesse the safety signals of chloroquine phosphate on various organs systems. RESULTS: Among the 2 063 reports of ADEs studied, 557 reports were considered to be mainly caused by chloroquine. The results demonstrated that the high-risk ADEs signals of chloroquine involved various systems, such as atrioventricular block complete (ROR=2.90, IC-2SD=1.64), ventricular fibrillation (ROR=3.40, IC-2SD=1.27), blindness (ROR=27.51, IC-2SD=0.55), cardiogenic shock (ROR=6.86, IC-2SD=0.54), vomiting (ROR=1.70, IC-2SD=1.83). Moreover, some rare ADEs with high-risk signals showed a correlation with chloroquine, including hypokalaemia (ROR=4.18,IC-2SD=1.51), renal failure acute (ROR=3.08, IC-2SD=0.30), methaemoglobinaemia (ROR=4.37, IC-2SD=0.03), and pyrexia (ROR=1.80, IC-2SD=1.84), which were consistent with literature reports. However, these ADEs were not listed in instruction and worth much attention in clinic. Moreover, basic diseases of patients and drug incompatibility need much attention to prevent the occurrence and exacerbation of chloroquine-related adverse reactions. CONCLUSION: A comprehensive analysis of the ADEs signals of chloroquine could shed some light on understanding of its safety characteristics and would provide valuable information for rational use of chloroquine in clinic, especially in treatment of COVID-19.

Discussion on the experience of organ donation after citizen's death under COVID-19 epidemic / 器官移植

Objective To summarize the experience of organ donation after citizen' s death during the novel coronavirus pneumonia (COVID-19) epidemic. Methods Eleven cases of potential donors of organ donation after citizen' s death during the COVID-19 epidemic were retrospectively analyzed, and the workflow and key points of infectionprevention and control were summarized. Results Among 11 cases of potential donors, 6 cases failed to implement organ donation. Five donors who were successfully performed organ donation had no respiratory symptoms before the onset of encephalopathy. CT scan of the lungs upon the onset of encephalopathy showed that one case was diagnosed with aspiration pneumonia, and the remaining four cases obtained negative results. During hospitalization, all of the 5 donors showed fever symptom and repeated chest CT scan detected lung inflammation. Bronchoalveolar lavage fluid or blood samples tested for novel coronavirus nucleic acids were all negative. No confirmed or suspected cases appeared among all staff and recipients who were in close contact with organ donors. Conclusions Targeted formulation of the workflow and prevention and control measures, in combination with selection and implementation of infection risk classification can effectivelyreduce the risk of COVID-19 infection and carry out organ donation after citizen' s death in a safe and organized manner.

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.

Medication rule of Chinese materia medica in treatment of pulmonary fibrosis based on data mining / 中草药

To explore the medication rule of Chinese materia medica (CMM) in the treatment of pulmonary fibrosis, and provide reference for the prevention and treatment of pulmonary fibrosis in the novel coronavirus pneumonia. Using Excel 2013 and SPSS Statistics 23.0, the literatures with the theme of “pulmonary fibrosis” that met the screening criteria were searched, and the association rule analysis was carried out. Frequency analysis showed that the occurrence frequency of Astragali Radix (148, 45.82%), Glycyrrhizae Radix et Rhizoma (124, 38.39%) and Salviae Miltiorrhizae Radix et Rhizoma (102, 31.58%) was the highest in the clinical treatment literature. In the statistics of nature and flavor, warm (10 times, 50.00%) and neutral (six times, 30.00%) were the most common. The highest frequency of meridian tropism was found in the spleen (11 times, 25.58%), lung (10 times, 23.26%) and sweet (11 times, 36.67%). In the analysis of association rules, six groups of TCM combinations with high frequency correlation strength were obtained. The high frequency and high correlation CMM combinations obtained from this data analysis were mainly effective in strengthening the spleen and invigorating qi, and warming the spleen and lung, which can be used to prevent the early patients from developing to the critical stage and prevent the patients from reinfection due to low immunity in the convalescence stage.

Progress in the diagnosis and treatment of novel coronavirus pneumonia by traditional Chinese medicine / 西安交通大学学报(医学版)

In December 2019, a new type of coronavirus pneumonia emerged and spread rapidly, but there is no specific antiviral vaccine or drug. At present, traditional Chinese Medicine (TCM) prevention and treatment programs have been introduced in many places in China. This paper systematically reviews and summarizes the etiology and pathogenesis of novel coronavirus pneumonia 2019 (COVID-19), the prevention programs for different populations in different regions and the treatment programs by stages. We analyzed the TCM prevention and treatment programs of COVID-19 in various regions and the clinical characteristics of the first-line patients. It is verified that the disease belongs to the category of "wet poison epidemic" according to TCM, and the disease is located in the lung and the spleen. The core pathogenesis of the disease is "dampness, heat, poison, blood stasis and deficiency" because of the rage of the disease. According to the relevant plan, TCM prevention should adopt different prescriptions according to the constitution of different populations and pay attention to comprehensive prevention according to different climates, regions and populations. Treatment should focus on eliminating filth and resolving turbidity, with clearing dampness as the key point. The corresponding treatment plan should be made according to the development of the disease, and the treatment should be divided into five stages (observation stage, initial stage, middle stage, severe stage and convalescence stage) according to the rules of syndrome development. Through the systematic analysis of the progress of TCM applied in various regions during the epidemic period, this paper hopes to provide useful help and guidance for the prevention and control of the epidemic and rational application and further research on the clinical treatment with TCM.
