OBJECTIVE: The aim of this study was to examine the effect of Liu-zi-jue exercise on the respiratory symptoms, quality of life, and mental health of patients with mild coronavirus disease 2019(COVID-19). METHODS: A single-center randomized controlled trial was conducted with 104 patients with mild COVID-19. The patients were randomly assigned to the Liu-zi-jue plus conventional therapy group and conventional therapy group. The outcome measures included Modified Borg Dyspnea Scale(MBDS) score, Patient Health Questionnaire-9(PHQ-9) score, Fatigue Scale-14(FS-14), respiratory symptoms, and vital signs. Data were collected on the first and sixth days of hospitalization and on the discharge day. RESULTS: Repeated-measures ANOVA revealed that the whole scales all showed a downward trend in the two groups(all P < 0.05). The results of single-group effect suggested that the whole scale score in the intervention group was significantly lower than that in the control group at the sixth day of hospitalization. Compared with the control group, only the MBDS, expectoration, and FS-14 scores showed significantly lower scores at the discharge day(P < 0.001, P = 0.011, P = 0.002). Comparison within the group showed that all the variables were significantly different at the three time points with a decreasing trend(P < 0.05), except for the PHQ-9 and expectoration scores(P = 0.331, 0.052). All patients’ vital signs remained within a stable normal range throughout the hospital stay. CONCLUSION: The results suggested that Liu-zi-jue exercise as a complementary and alternative therapy showed beneficial effects on improving the symptoms(shortness of breath, fatigue, and cough), quality of life, and mental health of patients with mild COVID-19.

As for the satellite remote sensing data obtained by the visible and infrared bands myers,on, the clouds coverage in the sky over the ocean often results in missing data of inversion products on a large scale, and thin clouds difficult to be detected would cause the data of the inversion products to be abnormal. Alvera et a1.（2005） proposed a method for the reconstruction of missing data based on an Empirical Orthogonal Functions （EOF） decomposition, but his method couldn＇t process these images presenting extreme cloud coverage（more than 95%）, and required a long time for recon- struction. Besides, the abnormal data in the images had a great effect on the reconstruction result. Therefore, this paper tries to improve the study result. It has reconstructed missing data sets by twice applying EOF decomposition method. Firstly, the abnormity time has been detected by analyzing the temporal modes of EOF decomposition, and the abnormal data have been eliminated. Secondly, the data sets, excluding the abnormal data, are analyzed by using EOF decomposition, and then the temporal modes undergo a filtering process so as to enhance the ability of reconstruct- ing the images which are of no or just a little data, by using EOF. At last, this method has been applied to a large data set, i.e. 43 Sea Surface Temperature （SST） satellite images of the Changjiang River （Yangtze River） estuary and its adjacent areas, and the total reconstruction root mean square error （RMSE） is 0.82℃. And it has been proved that this improved EOF reconstruction method is robust for reconstructing satellite missing data and unreliable data.

Quasars with redshifts greater than 4 are rare, and can be used to probe the structure and evolution of the early universe. Here we report the discovery of six new quasars with i-band magnitudes brighter than 19.5 and redshifts between 2.4 and 4.6 from spectroscopy with the Yunnan Faint Object Spectrograph and Camera (YFOSC) at the Lijiang 2.4 m telescope in February, 2012. These quasars are in the list of z > 3.6 quasar candidates selected by using our proposed J K/i Y criterion and the photometric redshift estimations from the SDSS optical and UKIDSS near-IR photometric data. Nine candidates were observed by YFOSC, and five among six new quasars were identified as z > 3.6 quasars. One of the other three objects was identified as a star and the other two were unidentified due to the lower signal-to-noise ratio of their spectra. This is the first time that z > 4 quasars have been discovered using a telescope in China. Thanks to the Chinese Telescope Access Program (TAP), the redshift of 4.6 for one of these quasars was confirmed by the Multiple Mirror Telescope (MMT) Red Channel spectroscopy. The continuum and emission line properties of these six quasars, as well as their central black hole masses and Eddington ratios, were obtained.
