OBJECTIVE To investigate the changes in serum metabolites of mice with radiation-induced intestinal injury under the intervention of baicalein and the changing characteristics of endogenous biological small molecules during the process of baicalein's participation in the prevention and treatment of radiation-induced intestinal injury through the metabolomics method based on GC-MS technology,in order to explore the potential regulatory mechanism of baicalein.METHODS A mouse radioactive intestinal injury model was established and randomly divided into normal control group,model group,low-dose baicalein group and high-dose baica-lein group.Baicalein was administered by gavage.Gas chromatography-mass spectrometry(GC-MS)technology was used to analyze the serum samples of mice in each group,and differential metabolites were screened through partial least squares-discriminant analysis(PLS-DA).Potential metabolic pathways were analyzed with MetaboAnalyst.RESULTS The pathological sections of mouse intesti-nal tissue showed that the high-dose and low-dose baicalein groups had a certain protective effect on radiation-induced intestinal dam-age.Metabolomic analysis showed that there were significant differences in the metabolic profiles of the blank control group,model group,low-dose and high-dose baicalein administration groups.After intragastric administration of baicalein,the endogenous metabo-lites in mice with radiation intestinal injury tended to normalize.The study screened out a total of 11 potential metabolic markers and 5 related metabolic pathways,among which pathways related to glucose metabolism,glutathione pathway,and ammonia metabolism were particularly significant.CONCLUSION Baicalein has a certain preventive and therapeutic effect on radiation-induced intestinal in-jury;baicalein participates in glucose metabolism and glutathione metabolism,and improving the endogenous substance disorder caused by radiation is its potential mechanism of action.

OBJECTIVE: To analyze the roles of multidisciplinary team (MDT) in the diagnosis and treatment of suspected cases of coronavirus disease 2019 (COVID-19). METHODS: The clinical data of 48 patients with suspected COVID-19 admitted in Jinhua Municipal Central Hospital from January 21, 2020 to March 20, 2020 were retrospectively analyzed. RESULTS: In the 48 suspected cases, 18 were diagnosed with COVID-19, and 30 were excluded. Each of the confirmed cases were discussed among MDT for 2 to 12 times with an average of (4.7±3.2) times; while for non-COVID-19 patients were discussed for 2 to 4 times with an average of (2.3±0.6) times. With the guidance of MDT, one COVID-19 patient was transferred to designated provincial hospital after effective treatment; one patient complicated with acute cholecystitis underwent gallbladder puncture and drainage; and COVID-19 was excluded in a highly suspected patient after alveolar lavage fluid examination. Except one transferred patient, all 17 confirmed COVID-19 patients were cured and discharged. There was no cross-infection occurred in suspected patients during the hospitalization. There were no deaths and no medical staff infections. CONCLUSIONS The efficiency of diagnosis and treatment for suspected COVID-19 patients can be improved with MDT, particularly for complicated cases.

OBJECTIVE: To analyze the roles of multidisciplinary team (MDT) in the diagnosis and treatment of suspected cases of corona virus disease 2019 (COVID-19). METHODS: The clinical data of 48 patients with suspected COVID-19 admitted in Jinhua Central Hospital from January 21, 2020 to March 20, 2020 were retrospectively analyzed. RESULTS: Of the 48 suspected cases, 18 were diagnosed with COVID-19, and 30 were excluded. Each of the confirmed cases were discussed among MDT for 2 to 12 times with an average of (4.7±3.2) times; while for non-COVID-19 patients were discussed for 2 to 4 times with an average of (2.3±0.6) times per case. With the guidance of MDT, one COVID-19 patient was transferred to designated provincial hospital after effective treatment; one patient complicated with acute cholecystitis underwent gallbladder puncture and drainage; and COVID-19 was excluded in a highly suspected patient after alveolar lavage fluid examination. Except one transferred patient, all 17 confirmed COVID-19 patients were cured and discharged; there was no cross-infection occurred in suspected patients during the hospitalization; there were no deaths and no medical staff infections. CONCLUSIONS The efficiency of diagnosis and treatment for suspected COVID-19 patients can be improved under MDT mode, particularly for complicated and refractory cases.
