    Objective: To explore the early clinical characteristics of coronavirus disease MESHD 2019 (COVID-19) and provide a reference for the early prevention and treatment of the disease.Methods: We collected and analyzed demographic data, medical history, exposure history, underline diseases MESHD, symptoms, signs, laboratory data, chest computed tomographic (CT) scans, and treatment measures of COVID-19 patients admitted to the Sixth People's Hospital of Hangzhou from January 20 to February 23, 2020.Results: Among 51 confirmed COVID-19 patients included in this study, 7.8% (4/51) patients were severe and 45.1% (23/51) were male TRANS. Median age TRANS was 43 years (IQR, 23). Fever HP Fever MESHD (54.9%, 28/51) and cough HP (52.9%, 27/51) were the main symptoms. 74.5% (38/51) patients had a history of exposure and 17.6% (9/51) patients had a history of hypertension HP hypertension MESHD. Importantly, most (60.8%, 31/51) patients had an increase of urine β2 microglobulin. In addition, the inflammation MESHD indexes (C-reactive protein and serum SERO amyloid A) of patients with elevated urine β2 microglobulin were significantly increased (p = 0.017 and p = 0.049) and lymphocytes count was significantly reduced (p = 0.012), compared with patients with normal urine β2 microglobulin. Correlation analysis showed that urine β2 microglobulin was positively correlated with C-reactive protein and serum SERO amyloid A; but negatively correlated with lymphocytes count.Conclusions: COVID-19 patients have obvious symptoms of lung injury MESHD, but the occurrence of early renal tubular injuries MESHD has to be monitored vigilantly.

    Background: Since December 2019, a severe novel coronavirus ( SARS-CoV-2) infection (Coronavirus Disease MESHD 2019,COVID-19) has occurred in Wuhan, China, and has rapidly spread to the country and around the world. This study intends to investigate the epidemiological and clinical characteristics of patients with COVID-19 in a surrounding city of Wuhan.Methods: A retrospective study was conducted on 208 cases of COVID -19 patients from February 11, 2020 to February 29, 2020 in Xiaogan dongnan Hospital, collected basic information, history of exposure, medical history, clinical symptoms, laboratory indicators and pulmonary imaging Data, and analyzed the epidemiological and clinical characteristics of all patients. According to the clinical classification criteria, 208 patients were divided into light group and ordinary group, and the epidemiological and clinical characteristics of the two groups were compared.Results: Among 208 patients in this study, with a median age TRANS of 50.5 years (IQR,36-64.7,range,10-91 years), among which 107 (51.4%) were males TRANS and 101 (48.6%) were females TRANS. 51 (24.5%) had a clear exposure to COVID-19 infection within 2 weeks before admission, and 40 (19.2%) had a history of residence or exposure in Wuhan within 2 weeks before admission. Among all the patients, there were 16 (7.7%) with pulmonary diseases MESHD, 41 (19.7%) with hypertension HP hypertension MESHD, 11 (5.3%) with coronary heart disease MESHD, 13 (6.3%) with diabetes MESHD, 12(5.8%) with a history of alcohol consumption, and 12(5.8%) with a history of smoking. Among all clinical symptoms, 146 cases (70.2%) of fever HP fever MESHD, the highest temperature range was 37.3℃-41℃ before admission, 115 (55.3%) cases of cough HP, and 57 (27.4%) cases of chest tightness HP chest tightness MESHD, 47 (22.6%) cases of fatigue HP fatigue MESHD, 28 (13.5%) cases of inappetence, 9 (4.3%) cases of diarrhea HP diarrhea MESHD, 7 (3.4%) cases of nasal congestion or runny nose , and 5 ( 2.4%) cases of pharyngalgia. Analysis of the laboratory results of 208 patients showed that 42 (20.2%) cases had decreased white blood SERO cell count, and 61 (29.3%) cases had decreased lymphocyte count. There were 154 (74%) cases with elevated CRP, 50 (24%) cases with elevated fasting blood SERO glucose, and 23 (11.1%) cases with elevated LDH (>245U/L). The comparison of clinical characteristics between the light group and the common group showed that the median age TRANS of the light group was 44.8 years (IQR 30-58), the median age TRANS of the common group was 53.1 years (IQR 38.8-67) (P<0.01). The symptoms of fever HP fever MESHD [53(80.3%) vs 93(65.5%),P<0.05], fatigue HP fatigue MESHD [53(80.3%) vs 93(65.5%),P<0.05] and inappetence [4(6.1%) vs 24(16.9%),P<0.05] in the light group were less than those in the common group. The white blood SERO cell count (5.48 vs 6.37, P<0.05), lymphocyte count (1.40 vs 1.61, P<0.05) and HDL-C (1.5 vs 1.3, P<0.05) of the common group were lower than that of the light group, while CRP (26.5 vs 22.1, P<0.01), AST (22.9 vs 18.5, P<0.05), fasting blood SERO glucose (5.8 vs 5.6, P<0.05), LDH (196.8 vs 157.9, P<0.001) of the common group were higher than that of the light group.Conclusion: COVID-19 infection is mainly in middle- aged TRANS and elderly TRANS patients, patients with other diseases MESHD are more susceptible to infection. The main symptoms of COVID-19 infection MESHD were fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, fatigue HP fatigue MESHD, and inappetence. Decreased lymphocyte count, increased CRP concentration, increased LDH concentration and decreased HDL-C concentration were the laboratory features of COVID-19 infection MESHD, and were important indicators to assess the severity of COVID-19 disease.

    Coronaviruses (CoVs) are positive-stranded RNA viruses that infect MESHD humans and animals. Infection by CoVs such as HCoV-229E, -NL63, -OC43 and -HKUI1 leads to the common cold, short lasting rhinitis HP rhinitis MESHD, cough HP, sore throat and fever HP fever MESHD. However, CoVs such as Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) MESHD, and the newest SARS-CoV-2 (the causative agent of COVID-19) lead to severe and deadly diseases MESHD with mortality rates ranging between ~1 to 35% depending on factors such as age TRANS and pre-existing conditions. Despite continuous global health threats to human, there are no approved vaccines or drugs targeting human CoVs, and the recent outbreak of COVID-19 emphasizes an urgent need for therapeutic interventions. Using computational and bioinformatics tools, here we present the feasibility of reported broad-spectrum RNA polymerase inhibitors as anti- SARS-CoV-2 drugs targeting its main RNA polymerase, suggesting that investigational and approved nucleoside RNA polymerase inhibitors have potential as anti-SARS-CoV-2 drugs. However, we note that it is also possible for SARS-CoV-2 to evolve and acquire drug resistance mutations against these nucleoside inhibitors.

    Objective: The novel coronavirus disease MESHD (COVID-19) was first reported in Wuhan, China in December 2019 and is now pandemic all over the world. Previous study has reported several COVID-19 cases with conjunctivitis HP conjunctivitis MESHD. However, the complete profiling of COVID-19 related ocular symptoms and diseases MESHD are still missing. We aim to investigate the ocular manifestations and clinical characteristics of COVID-19 patients. Methods: A total of five hundred and thirty-four patients were recruited at Mobile Cabin Hospital and Tongji Hospital. We collected information on demographic characteristics, exposure history, ocular symptoms, systemic concomitant symptoms, eye drop medication, eye protections, radiologic findings, and SARS-CoV-2 detection in nasopharyngeal swabs by RT-PCR from questionnaires and electronic medical records. Results: The median age TRANS of patients was 40 and 50 years at Mobile Cabin Hospital and Tongji Hospital, respectively. Of 534 COVID-19 patients, 25 patients (4.68%) presented with conjunctival congestion and 3 patients had conjunctival congestion as the initial symptom. The average duration of conjunctival congestion was 4.9 {+/-} 2.6 days (mean [SD]), ranging from 2 to 10 days. Dry eye (112, 20.97%), blurred vision HP blurred vision MESHD (68, 12.73%), and foreign body sensation (63, 11.80%) ranked as the top three COVID-19 related ocular symptoms. Notably, a total of 332 COVID-19 patients (62%) had a hand-eye contact history. We also found that some COVID-19 patients had a history of eye disease MESHD, including conjunctivitis HP conjunctivitis MESHD (33, 6.18%), dry eye MESHD (24, 4.49%), keratitis HP keratitis MESHD (14, 2.62%), cataract HP cataract MESHD (9, 1.69%), and diabetic retinopathy MESHD retinopathy HP (5, 0.94%). In consistent with previous studies, the most common clinical symptoms were fever HP fever MESHD, cough HP cough MESHD, and fatigue HP fatigue MESHD. Patients, 60.5% in Mobile Cabin Hospital and 67.5% in Tongji Hospital, respectively were confirmed with positive SARS-CoV-2 detection. Conclusions: Conjunctival congestion was one of the COVID-19 related ocular symptoms, which may have clinical diagnostic significance. It is essential to provide eye-care equipment and strengthen education on eye protection, as dirty hand-eye contact might be a high risk factor of COVID-19. Further detailed and comprehensive ophthalmological guidance is needed for COVID-19 control.
