[ Objective] The present paper aimed to reasonably use local agricultural climate resources and scientifically carry out maize planting. [ Method] According to climate data (1961 -2017) of 124 meteorological stations and long-term records (1981 - 2017) of maize phenology from 15 agricultural stations of Sichuan, the temporal and spatial distribution of light resources, temperature resources and precipitation during key maize phenological stages were analyzed in Sichuan Province. [Result] The total radiation during the whole growing period and different growth stages of maize both showed decreased trends. The higher radiation resources distributed to the southwestern of the basin and the southern of the Panxi agricultural area. The heat resources during maize growth period showed an increasing trend. Diurnal temperature range of Panxi agricultural area is obviously higher than the basin area. The reference evapotranspiration during each maize growth stages decreased. Water resources shortage occurred in most Panxi agricultural area and the old arid areas in the basin. [ Conclusion ] All regions should make rational use of light, temperature and water resources to provide scientific basis for relevant departments to formulate agricultural production measures and ensure the development of high yield and high quality of corn.

Objective To investigate the correlation between the changes of major atmospheric pollutants, meteorological factors in Shihezi city and the number of hospitalized children with pneumonia. Methods The data of hospitalizations of children with pneumonia in two grade III A hospitals in Shihezi city were collected from January 1, 2015 to December 31, 2017. Pearson and Spearman were used to investigate the impact of major atmospheric pollutants and meteorological factors on the number of hospitalized children with pneumonia through analyzing the data of major atmospheric pollutants and meteorological factors in the same period. Results In the past 3 years, the particulate matter 2. 5 (PM2. 5) , sulfur dioxide(S02) and nitrogen dioxide(N02) showed cyclical and seasonal changes obviously in Shihezi city. The monthly average concentration of PM, 5 and NO2, in winter were signifi cantly higher than the National annual mean level II standard for ambient air quality, excepted SO2, . Besides the average tempera ture, there were positive correlations between the atmospheric pollutants and meteorological factors (P < 0. 05) . The atmospheric pollutants were positively correlated with the number of hospitalized children with pneumonia in the city (P < O. 05) , among which, the impact of NO2, ranked number one, followed by PM2.5, and SO2, ranked last. Effects of atmospheric pollutions on the number of boys with pneumonia were significantly higher than those on girls. The meteorological factors, especially the temperature, had the grea test influence on the number of hospitalized children, which had a significant negative correlation(P< O. 05) . Conclusions There are obvious correlations between atmospheric pollutions and meteorological factors in Shihezi city. They all affect the number of hospitalized children with pneumonia in varying degrees, and the impact on boys are greater than those on girls. Therefore, it is necessary to strengthen control atmospheric pollutions to reduce the number of hospitalized children with pneumonia. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of goal directed fluid therapy under the guidance of different stroke volume variabilities ( SVV) on fibrinogen ( Fg) and D-dimer after hip replacement. Methods Fifty elderly patients with elective total hip replacement in the hospital from July 2016 to November 2018 were selected and divided into the group A and B by adopting the randam number table method,25 cases in each group. The group A maintained intraoperative SVV in 6 % - 9 %, and the group B maintained SVV in 10 % -15 % . The intake and output volumes of fluid during the operation and at 24 h after the operation were recorded. The levels of fibrinogen (Fg) and D-dimer before the operation ( TO),at postoperative 6 h (T3 ) and 24 h ( T 4) were recorded; the mean arterial pressure (MAP) and heart rate were recorded before the operation (T O), at the anesthesia induction(Tl ) and 2 h after the peration beginning(T2) ; intraoperative sustained hypotension( with MAP decrease exceeding the baseline value by 30 % as the diagnostic standard of hypotension) occurrence rate, and the occurrence rates of thrombus and cardiovascular events within postoperative 7 d were recorded. Results The general data such as sex, age, body weight index and ASA grade had no statistical differences between the two groups ( P > 0. 05). T he intraoperative crystal fluid volume, colloid fluid volume, intraoperative and postoperative 24 h urine volume in the group A were significantly increased compared with the group B, and the differences were statistically significant( P < O. 05) ; the Fg and D-dimer levels at T 3 and T4 in the two groups were significantly decreased compared with before operation. The occurrence rate of hypotension persistent for 1 min in the group A was 20 % ( 5/25), which was significantly lower than 44 % (11 / 25) in t he group B, and t he difference was statistically significant ( P O. 05). Conclusion The intraoperative fluid therapy guided by SVV can effectively reduce the incidence of sustained hypotension and improve the state of blood hypercoagulability. [ABSTRACT FROM AUTHOR]
