Up to 29 February 2020,SARS-CoV-2(HCoV-19/2019-nCoV) had infected more than 85 000 people in the world. In this study,we used 93 complete genomes of SARS-CoV-2 from the GISAID EpiFlu TM database to investigate the evolution and human-to-human transmissions of SARS-CoV-2 in the first two months of the outbreak.We constructed haplotypes of the SARS-CoV-2 genomes, performed phylogenomic analyses and estimated the potential population size changes of the virus. The date of population expansion was calculated based on the expansion parameter tau(τ)using the formula t=τ/2 u. A total of 120 substitution sites with 119 codons, including 79 non-synonymous and 40 synonymous substitutions, were found in eight coding-regions in the SARS-CoV-2 genomes.Forty non-synonymous substitutions are potentially associated with virus adaptation. No combinations were detected. The 58 haplotypes(31 found in samples from China and 31 from outside China)were identified in 93 viral genomes under study and could be classified into five groups. By applying the reported bat coronavirus genome(bat-RaTG13-CoV)as the outgroup, we found that haplotypes H13 and H38 might be considered as ancestral haplotypes,and later H1 was derived from the intermediate haplotype H3. The population size of the SARS-CoV-2 was estimated to have undergone a recent expansion on 06 January 2020, and an early expansion on 08 December 2019. Furthermore,phyloepidemiologic approaches have recovered specific directions of human-to-human transmissions and the potential sources for international infected cases. 展开更多

The novel coronavirus pneumonia triggered by COVID-19 is now raging the whole world.As a rapid and reliable killing COVID-19 method in industry,electron beam irradiation can interact with virus molecules and destroy their activity.With the unexpected appearance and quickly spreading of the virus,it is urgently necessary to figure out the mechanism of electron beam irradiation on COVID-19.In this study,we establish a virus structure and molecule model based on the detected gene sequence of Wuhan patient,and calculate irradiated electron interaction with virus atoms via a Monte Carlo simulation that track each elastic and inelastic collision of all electrons.The characteristics of irradiation damage on COVID-19,atoms’ionizations and electron energy losses are calculated and analyzed with regions.We simulate the different situations of incident electron energy for evaluating the influence of incident energy on virus damage.It is found that under the major protecting of an envelope protein layer,the inner RNA suffers the minimal damage.The damage for a^100-nm-diameter virus molecule is not always enhanced by irradiation energy monotonicity,for COVID-19,the irradiation electron energy of the strongest energy loss damage is 2 keV. 展开更多

The main symptom elements of the severe novel coronavirus pneumonia epidemic virus closed lung syndrome are cold, damp, poisonous, heat, dryness, blood stasis, and deficiency, which mainly involve the lung and spleen, and are closely related to the heart, liver, kidney, and large intestine. Chinese medicine has accumulated rich academic theories and clinical experience in the prevention and treatment of infectious diseases. The treatment of lung syndrome recommends the use of Huashibaidu formula in the treatment of novel coronavirus pneumonia with integrated traditional Chinese and western medicine. The prescription for removing dampness and detoxification is composed of Maxingshigan formula in "Treatise on Febrile Diseases", "Tingli Dazao Xiefei formula" in "An Outline of Jinkui", Xuanbai Chengqi formula in "Diagnosis of Warm Diseases", "Medical Source Moisture" The combination of four prescriptions of Huopu Xialing formula in "On" is made according to the specific requirements. Through the composition of the prescription of Huashibaidu formula and the pharmacological research involving drugs, the mechanism of the novel coronavirus pneumonia severe epidemic closed lung syndrome may be combined with the blocking of cytokine inflammation storm, immune regulation, antispasmodic and asthma, and improvement Related to hemodynamics. 展开更多

The mean time between the initial and repeat thin-section CT scans was 3.3 <span style="white-space:nowrap;">±</span> 2.1 days, 7.9 <span style="white-space:nowrap;">±</span> 2.1 days, 14.2 <span style="white-space:nowrap;">±</span> 1.3 days after onset of symptoms in these 15 patients. Three experienced Radiologists reviewed the CT images independently and also in collaboration with each other for complicated or unique cases, for the Imaging characteristics like number and site of lesions, distribution of lesions whether it is lobular, lobar, unilateral or bilateral, and comparing the severity of disease in relation to the CT findings. The CT features were compared using the χ<sup>2</sup> test and <em>Fisher’s </em>exact probability.<strong> Results:</strong> All of 15 patients had a history of visit to the endemic center <em>i.e.</em> Wuhan city or came in direct contact with an infected individual. Fever (93.3%) was the most common symptom. Majority of patients had a normal white blood cell count, and normal lymphocyte count although there were patients with leucopenia and lymphocytopenia. CT images showed predominate Ground-Glass opacities in the initial and repeat CT scans with a percentage of 90.6%, 53.9%, 44.2% respectively during the three spaced CT examinations;most patients had bilateral lung involvement (60%, 93.3%, 93.3%), the lesions predominantly involved the posterior (87.5%, 71.9%, 76.6%) and peripheral (90.6%, 84.3%, 85.7%) part of the lungs. There were more consolidation and mixed patterns in repeat CT scan Versus initial CT scan, the difference was statistically significant (P-values were < 0.001). The total lung severity score in the three aforementioned timely spaced CT scans were 36 (3.3 <span style="white-space:nowrap;">±</span> 2.1 days) 63 (7.9 <span style="white-space:nowrap;">±</span> 2.1 days), and 57 (14.2 <span style="white-space:nowrap;">±</span> 1.3 days) respectively. The median percentage of pneumonia lesions of the whole lung volume in three times CT scan was 1.69% (4.59), 3.47% (5.46), 2.33% (4.75) respectively. Besides, “Tree-in-bud” sign, lung cavitation, and lymphadenopathy were absent. <strong>Conclusion:</strong> The Thin-slice Section CT Imaging features show uniquely different characteristics, each time the scans are taken. The most common findings in our study were bilateral multiple peripheral and mostly posterior ground-glass opacities (GGO), however the CT scan images that were taken in a timely manner to follow up demonstrated some remarkable changes, which undoubtedly play an important role in the diagnosis and management of the patient with COVID-19 disease. 展开更多

Influenza viruses were responsible for most adult viral pneumonia.Presently,coronavirus disease 2019(COVID-19)has evolved into serious global pandemic.COVID-19 outbreak is expected to persist in months to come that will be synchronous with the influenza season.The management,prognosis,and protection for these two viral pneumonias differ considerably and differentiating between them has a high impact on the patient outcome.Reverse transcriptase polymerase chain reaction is highly specific but has suboptimal sensitivity.Chest computed tomography(CT)has a high sensitivity for detection of pulmonary disease manifestations and can play a key-role in diagnosing COVID-19.We reviewed 47 studies and delineated CT findings of COVID-19 and influenza pneumonia.The differences observed in the chest CT scan can be helpful in differentiation.For instance,ground glass opacities(GGOs),as the most frequent imaging finding in both diseases,can differ in the pattern of distribution.Peripheral and posterior distribution,multilobular distribution,pure or clear margin GGOs were more commonly reported in COVID-19,whereas central or peri-bronchovascular GGOs and pure consolidations were more seen in influenza A(H1N1).In review of other imaging findings,further differences were noticed.Subpleural curvilinear lines,sugar melted sign,intra-lesional vascular enlargement,reverse halo sign,and fibrotic bands were more reported in COVID-19 than H1N1,while air space nodule,tree-in-bud,bronchiectasia,pleural effusion,and cavitation were more seen in H1N1.This delineation,when combined with clinical manifestations and laboratory results may help to differentiate these two viral infections. 展开更多

COVID-19 disease is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) that mainly presents with pneumonia, but has variable multi-systemic manifestations. Concomitant bacterial infections associated with the acute stage of COVID-19 disease have been rarely reported in the literature. However, to our knowledge, post viral organizing pneumonia (OP) secondary to bacterial infection after recovery from SARS-CoV2 infection has not been noted before. We report a 27-year-old male patient with Type 1 Diabetes Mellitus who presented with fever post recovery from COVID-19 disease for seven weeks and was found to have OP secondary to<em> Klebsiella pneumoniae</em>. Furthermore, the bronchoalveolar lavage was positive for SARS-CoV2 by RT-PCR despite multiple negative nasopharyngeal RT-PCR. The patient was successfully treated with antibiotics only. Therefore, we conclude that early recognition of OP secondary to bacterial infection in patients with COVID-19 disease and prompt antibiotic treatment could avoid the use of a prolonged course of steroids. 展开更多
