Objective:To explore the method of selecting the supporting institutions of the national clinical medical research center by using the third-party evaluation data.Methods:Select disease fields/clinical specialties as research objects based on the criteria of having at least 5 national clinical research centers established in the field of major diseases and at least 3 established in the field of non major diseases. Collected data on the ranking of scientific and technological evaluation metrics in Chinese hospitals from the official website of the Institute of Medical Information, Chinese Academy of Medical Sciences, and collected standardized research value ranking data on the reputation ranking of Chinese hospitals and specialties from the official website of Fudan University. Based on the correspondence between the disease field/clinical specialty and the disciplines and specialties in the two major rankings, the top 5 and top 10 hospitals in the corresponding disease fields/clinical specialties in the two ranking lists were selected respectively, and the comprehensive scores of the included hospitals were calculated using the grade scoring method and ranked accordingly. Then, determine the number of hospitals to be selected based on the criteria of fully covering the recognized national clinical medical research centers supporting institutions.Results:The study focused on six disease fields/clinical specialties, including chronic kidney disease, obstetrics and gynecology, digestive system diseases, oral diseases, hematological diseases, and eye, ear, nose, and throat diseases. In the hospital ranking list formed by the top 5 hospitals included in the two rankings, a maximum of 11 hospitals needed to be included to fully cover the recognized supporting institutions, while in the hospital ranking list formed by the top 10 hospitals included in the rankings, a maximum of 6 hospitals needed to be included to achieve full coverage. Therefore, the optimal selection method was to include the top 10 hospitals in the two rankings and calculate their comprehensive scores, and select the top 6 hospitals based on their comprehensive scores.Conclusions:The selection method based on the third-party evaluation data is scientific and reliable, and can provide reference for the evaluation work of the management department of the national clinical medical research center.

Objective:To investigate the clinical features and prognosis of patients with corona virus disease 2019 (COVID-19).Methods:The clinical data and chest computed tomography (CT) results of 496 patients with COVID-19 admitted to Wuhan No.7 Hospital from January 22 to February 24, 2020 were retrospectively analyzed. The nucleic acid of 2019 novel coronavirus (2019-nCoV) was detected by real-time fluorescence reverse transcription polymerase chain reaction.Results:There were 246(49.6%) males and 250(50.4%) females. The patients ranged from 10 to 91 years old. All of the patients had a history of living in Wuhan City or close contact with diagnosed patients. The detection of nucleic acid of 2019-nCoV in 496 patients were all positive, and one patient was recuperation positive 14 days after cured and discharged. There were 13 mild cases, 101 ordinary cases, 337 severe cases and 45 critical cases. Twelve (2.4%) patients were asymptomatic, 417(84.1%) patients had fever, and 67(13.5%) had normal body temperature. Other major symptoms included dry cough (229 cases (46.2%)), fatigue (129 cases (26.0%)), short breath (77 cases (15.5%)), expectoration (86 cases (17.3%)), dyspnea (43 cases (8.7%)), chest pain (11 cases (2.2%)) and diarrhea (86 cases (17.3%)). Seventy-five cases (15.1%) showed decreased peripheral blood white blood cell counts and 305 cases (61.5%) showed decreased lymphocyte proportions. Serum alanine aminotransferase and aspartate aminotransferase elevations were presented in 91 cases (18.3%) and 176 cases (35.5%), respectively. Infiltrates on chest CT were seen in 483 cases (97.4%), with 68.7%(332/483) in both lungs, 20.3%(98/483) in right lung, 11.0%(53/483) in left lung. No infiltrates on chest CT were seen in 13(2.6%) patients. As of February 24, 2020, 120(24.2%) patients were cured and discharged, 102(20.6%) patients improved, 52(10.5%) patients died, and the remaining patients were still under treatment. Among the dead patients, 16 cases (30.8%) aged from 61 to 70 years old, 32 cases (61.5%) aged≥71 years old, and 38 cases (73.1%) had underlying diseases.Conclusions:The COVID-19 lesions mainly involve both lungs. The main clinical features are fever and dry cough. The CT imaging findings of the lungs are mostly frosted hyaline. Peripheral white blood cell and leukomonocyte counts are decreased or normal. Older individuals with underlying diseases have increased risk of death.
