AIM: To study the antioxidative effect of three kinds of xanthone:methylswertianin(MET), bellidifodin(BEL) and decussatin (DEC) extracted from Swertia macrosperma C.B. clark. METHODS: Hydroxy radical was generated from H_2O_2 and VC-Fe~ 2+ system; MDA contents in liver homogenate and mitochondria were measured by thiobabituric acid assay; the hemolysis of RBC and the swelling extent of mitochondria were detected by spectrophotometric methods. RESULTS: Xanthones could inhibit the generation of MDA, the hemolysis of RBC, and the swelling of mitochondria. The inhibitory effect of BEL was stronger than that of MET and DEC. CONCLUSION: Xanthones possess a good antioxidant activity.

Objective:
To evaluated the application of General Provisions of Safety and Health for Writing Boards(GB 28231-2011), and to provide basis for the revision and improvement of the standard.
Methods:
From June to October 2018, a questionnaire survey was conducted among 852 people engaged in the evaluation, use and production of writing boards in 8 districts of Beijing, Liaoning and Jiangsu. The contents of the survey include the awareness, implementation of the standard and evaluating the use of various parameters in the standard by personnel from different institutions.
Results:
The overall awareness ratio of the standard among staffs from health, education and enter prise was 78.26%. For the nominal size of the writing board and the vertical distance between the lower edge and the platform, the reasonableness considered lower by health professionals(62.50%, 37.50%) than that of education professionals(90.00%, 90.00%) and enterprise staffs(90.00%, 90.00%)(P<0.05); For the frequency and reasonableness of the nine parameters such as gloss and adhesion, the perception of each institution were significantly different(P<0.05), with proportion of professionals in health lower than experts in education and enterprise. For the two parameters of color and light resistance, each institution considered the maneuverability was not strong(P>0.05).
Conclusion
Propagation and implement is still needed to strengthen comprehension, because different institutions have different understandings towards the standard. There are still some problems waiting to be solved, such as different standard limits, poor enforceability of two parameters which are writing board color and light resistance.

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.

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.
