Objective To study the effect of light intensity and light quality on the growth and total flavonoid accumulation of Erigeron breviscapus. Methods Young plants of E. breviscapus were planted under various color films and light intensities, their biomass and total flavonoid content were determined when plants flowered. Results The biomass and total flavonoid content of individuals under 100% and 80% sunshine were higher than those under 50% sunshine. The biomasses of plants under yellow, red, purple, or blue film were lower than those under white film. Under the blue film, the total flavonoid content of the plant was the highest; while under white film, the total flavonoid yield was the highest. Conclusion Light intensity and light quality significantly affect the growth and total flavonoid accummulation of E. breviscapus. The biomass and total flavonoid yield are the highest when under full sunshine.

Objective To analyze the influence of comprehensive nursing intervention on the treatment effect of children aged 8-12 years with bronchial asthma. Methods A total of 110 asthmatic children admitted in our hospital from January 2016 to January 2017 were selected and randomly divided into two groups according to random number table method, with 55 cases in each group. The control group was given random symptomatic nursing, and the observation group was given comprehensive nursing. The clinical efficacy and treatment compliance between the two groups after treatment was compared. Results After treatment, the total effective rate in the observation group was 98. 2%, which was significantly higher than that in the control group (74. 5%). The difference between the two groups was statistically significant(P<0. 05). The compliance rate of the observation group was 98. 2% after treatment, which was significantly higher than that of the control group after treatment(74. 5%). There was significant difference between the two groups in treatment compliance(P<0. 05). Conclusion The comprehensive nursing intervention combined with treatment in chil dren aged 8-12 years old with bronchial asthma is conducive to the active treatment of children, improve treatment compliance, thereby significantly improve the therapeutic effect.

Objective:
To analyze the spatial distribution and both hot and cold spots of incidence on Brucellosis in Gansu province from 2013 to 2018.
Methods:
Based on data from the Infectious Disease Reporting Information System in China, data related to space-time distribution and both hot and cold spots of Brucellosis in Gansu province from 2013 to 2018 were analyzed, by using the ArcGIS 10.5 software and GeoDa 1.6 software.
Results:
The trend surface analysis showed that the incidence of Brucellosis decreased gradually from the northern to southern parts with slightly higher in the west than in the east of Gansu. Global spatial autocorrelation analysis showed that the Moran’s

Objective:
To analyze the epidemiological and spatial-temporal distribution of Brucellosis, epidemic encephalitis B and hemorrhagic fever with renal syndrome (HFRS) in Gansu province during 2014-2018 so as to provide evidence for the prevention and control of those diseases.
Methods:
A database was established in Gansu province from 2014 to 2018, using the geographical information system. A spatial distribution map was drawn, with trend analysis and space-time clustering used to study the 3-dimention of the diseases, by using both ArcGIS 10.5 and SaTScan 9.6 softwares.
Results:
Results from the trend surface analysis showed that the incidence of Brucellosis decreased gradually from north to south parts while the U type curve could reflect the distribution from the east to the west areas. Incidence of epidemic encephalitis B decreased significantly from south to north areas in the province, with incidence higher in the eastern than in the mid-west region. Difference on the incidence of HFRS was not significantly visible in the eastern and western regions, while the incidence was slightly higher in the southern than the northern parts of the province. Spatial and space-time clustering did exist among the 3 diseases in Gansu from 2014 to 2018. The areas with clusters of Brucellosis appeared in the eastern parts during 2014-2015, including 19 counties. The areas with secondary clusters of Brucellosis were seen in the Hexi district, including 4 counties, during 2017-2018. The areas with high incidence of epidemic encephalitis B were clustered in the middle and southeast areas, including 32 counties, during 2017-2018. Areas with most clusters of HFRS appeared in Min county of Dingxi city in 2018, with the areas of secondary clusters in 8 counties of the eastern areas in 2018.
Conclusions
The overall incidence rates of the 3 natural focus diseases were in a upward trend and showing obvious characteristics on spatial clustering. According to the distributive characteristics, effective measures should be developed accordingly.
