Orchards are an important land use type in southern China; the total area （1.15 x 107 ha） of orchards in China comprises approximately 20.5% of the area of all orchards worldwide. We assessed soil organic C stocks （SOCS） in citrus orchards in Yongchun County （consisting of 22 towns）, Fujian Province, China in 1982 and 2010. The southeastern part of the county, an area featuring extensive citrus farming with a gently sloping landscape and low rates of water erosion, had the highest SOCS. In contrast, the lowest SCOS was observed in the northern part of the county, where steep hills with severe erosion problems are common and citrus orchards are sparsely distributed. From 1982 to 2010, the mean SOCS in citrus orchards increased from 22.1 to 41.7 Mg ha-1 which indicated that current management practices such as fertilization, irrigation, and cultivation enhanced soil C stocks. Further in-depth studies on the effects of these practices on C sequestration would be worthwhile and surveys of SOCS throughout Fujian Province are needed, to support efforts to mitigate global C emission.展开更多

Methods: a total of 98 patients with rheumatic immune diseases and pulmonary complications admitted to our hospital from July 2019 to September 2020 were randomly selected as the research object. They were randomly divided into two groups and then applied with different nursing programs. The analysis group of 49 patients received clinical nursing intervention, and the preset group of 49 patients received routine nursing. The nursing effects of the two groups were compared. Results: the incidence rate of pulmonary complications, hospitalization time and hospitalization expenses of the analysis group were lower than those of the preset group, and the patients' nursing satisfaction was higher than that of the preset group, with significant difference between the groups (P < 0.05). Conclusion: clinical nursing intervention can reduce the risk of pulmonary complications, hospitalization time and treatment costs in patients with rheumatic immune diseases with pulmonary complications. Patients have high satisfaction with nursing and are suitable for promotion.展开更多

Methods: 120 subjects were included in this study, all of whom belonged to rheumatic immune diseases. The patients were randomly divided into two groups by computer. One group was the reference group, which was divided into 60 patients, and the other group was the experimental group, which was equally divided into 60 patients. The reference group adopted the conventional nursing mode, while the experimental group adopted the refined management mode, and compared the application effects obtained under different nursing modes. Results: the improvement of psychological state and nursing satisfaction of the experimental group were significantly better than those of the reference group (P < 0.05). Conclusion: refined management intervention on rheumatic immune diseases can promote the improvement of patients' psychological state, actively cooperate with doctors for treatment, improve patients' satisfaction with nursing care, and build a harmonious nurse-patient relationship, which is worthy of recommendation.展开更多
