ABSTRACT
Objective: To retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 COVID-19 and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. Method(s): The propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group,and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms,disappearance time of main symptoms,efficacy on traditional Chinese medicineTCMsymptoms,hospitalization duration,laboratory test indicators,and CT imaging changes in the two groups were compared. Result(s): The general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment,the disappearance rate of fever,cough, fatigue,dry throat,anorexia,poor mental state,and poor sleep quality in the observation group was higher than that in the control groupP<0.05,and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms,the main symptomsfever, cough,fatigue,dry throat,anorexia,chest distressdisappeared earlier in the observation group than in the control groupP<0.01. After 7 days of treatment,the scores of the TCM symptom scale of both groups decreasedP<0.01,and the decrease of the observation group was larger that of the control groupP<0.01. All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group12.79+/-2.68dwas shorter than that in the control group15.27+/-3.11dP<0.01. The effective rate in the observation group92.31%,24/26was higher than that in the control group76.92%,20/26. After 7 days of treatment,the lymphocyteLYMcount increasedP<0.05,and white blood cellWBCcount and neutrophilNEUTcount decreased insignificantly in the two groups. Moreover,levels of C-reactive protein CRP,erythrocyte sedimentation rateESR,and procalcitoninPCTreduced in the two groups after treatmentP<0.01and the reduction in the observation group was larger than that in the control group P<0.01.

ABSTRACT
To put forward effective balance strategy of station-freesh a ring bike soncampus, massive trip data of station-free sharing bikes before the COVID-19 occurring on Southeast University were mined. The trip data included 15 687 trip productions and 15 410 trip attractions. Firstly, the data's temporal and spatial characteristics were analyzed, and a short-term travel prediction model for station-free sharing bikes on campus at intervals of 15 and 30 min separately using autoregressive integrated moving average (ARIMA) was established. Then, an identification method of station-free sharing bikes hot spots on campus by combining the density-based spatial clustering of applications with noise (DBSCAN) clustering method and the K-dist graphs was constructed. Finally, the management and control strategy was proposed for station-free sharing bikes on campus. The results show that imbalanced spatial and temporal demand of bike sharing trips on campus. From temporal demand, the average daily campus trip volume of station-free sharing bikes on weekdays is significantly higher than that on weekend, and the peak of daily campus trip volume occurs on Monday. The campus trip peak hours of station-free sharing bikes are closely related to the school time of teachers and students. The peak hours of trip origins are 07:00 to 08 : 00 and 13:00 to 14:00 on weekdays, and the peak hours of trip destinations are 11:00 to 12:00 and 17:00 to 18:00 on weekdays. From spatial demand, the origin and destination locations of station-free sharing bikes appear obvious distribution of "hot spots", and the parking hot spots are concentrated in the school gate, library, gymnasiums and important teaching buildings. The time series forecasting model is developed and the mean absolute error value is between 0. 600 to 0. 989, and it indicating a high prediction accuracy of the model. The time series forecasting model can provide technical support for real-time scheduling of station-free sharing bikes on campus. By predicting the temporal and spatial travel demand of station-free sharing bikes on campus, research results can help establish sharing bikes' delivery or allocation mechanism which are adapt to campus space capacity, parking hardware facilities, travel demand distribution and so on. Meanwhile, research results can provide the basis for campus administrators and sharing bikes operators to optimize sharing bikes parking management on campus. 7 tabs, 9 figs, 26 refs. © 2022 Editorial Department of Journal of Chang'an University (Natural Science Edition).

A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group，and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms，disappearance time of main symptoms，efficacy on traditional Chinese medicine（TCM）symptoms，hospitalization duration，laboratory test indicators，and CT imaging changes in the two groups were compared. Result： The general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment，the disappearance rate of fever，cough， fatigue，dry throat，anorexia，poor mental state，and poor sleep quality in the observation group was higher than that in the control group（P<0.05），and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms，the main symptoms（fever， cough，fatigue，dry throat，anorexia，chest distress）disappeared earlier in the observation group than in the control group（P<0.01）. After 7 days of treatment，the scores of the TCM symptom scale of both groups decreased（P<0.01），and the decrease of the observation group was larger that of the control group（P<0.01）. All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group［（12.79±2.68）d］was shorter than that in the control group［（15.27±3.11）d］（P<0.01）. The effective rate in the observation group（92.31%，24/26）was higher than that in the control group（76.92%，20/26）. After 7 days of treatment，the lymphocyte（LYM）count increased（P<0.05），and white blood cell（WBC）count and neutrophil（NEUT）count decreased insignificantly in the two groups. Moreover，levels of C-reactive protein （CRP），erythrocyte sedimentation rate（ESR），and procalcitonin（PCT）reduced in the two groups after treatment（P<0.01）and the reduction in the observation group was larger than that in the control group （P<0.01）.

ABSTRACT
As the first mRNA-based COVID-19 vaccine received Emergency Use Authorization (EUA) in 2020, its great safety profile and high protection efficacy has been well demonstrated. As a result of its unique advantage in the mechanism of action, mRNA can effectively trigger strong humoral and cellular immune response. Of note, many other prophylactic or therapeutic mRNA vaccines developed for preventing different infectious diseases or treatment of cancer are under clinical trial investigations. mRNA-based protein supplementation and gene therapy also begin to emerge. There will be bigger stage for the development of mRNA technology-based products, posing a revolutionary effect in the field of biopharmaceuticals.
ABSTRACT
OBJECTIVE: Based on the latest epidemic situation and field experience, this study aims to explore the correlation of computed tomography (CT) stages and blood glucose level in patients with novel coronavirus pneumonia (COVID-19). PATIENTS AND METHODS: The clinical data of first and multiple CT imaging re-examination and blood glucose levels from 62 confirmed cases of COVID-19 were collected for a retrospective analysis to determine the correlation between glucose level and CT-based staging. RESULTS: Of the 62 COVID-19 patients, 48 cases of early stage and 14 cases of advanced stage were found in the CT data of the first diagnosis. These 62 cases were currently under follow-up (17-32 days): 18 cases in early stage-resorption stage, 25 cases in early stage-advanced stage-resorption stage, 12 cases in advanced stage-resorption stage, 5 cases in early stage -advanced stage-severe stage-resorption stage, and 2 cases in advanced stage-severe stage-resorption stage. Among them, the CT of 14 patients with advanced stage at the first diagnosis showed multiple stage lesions (advanced stage + early stage) at the same time. Patients presented with statistically significant changes in blood glucose at early stage-resorption stage, early stage-advanced stage-resorption stage, advanced stage-resorption stage, and early stage-advanced stage-severe stage-resorption stage (p<0.05). However, no statistically significant alterations were observed in the glucose level of patients with advanced stage-severe stage-resorption stage (p>0.05). CONCLUSIONS: Alteration of blood glucose is positively correlated with CT-based staging of COVID-19. Blood glucose is of great value in clinical diagnosis of COVID-19 and in determining the stage and prognosis of this disease.
