The tax design of nitrogen fertilizer was discussed by utilizing the external theory and the demand elasticity theory. The results indicated that the coefficient of price elasticity of nitrogen fertilizer demand is -0.21, which instructed that the market demand is in lack of elasticity in the short period and the impact of nitrogen fertilizer manufacturers is subtle. The 11 counties （cities and boroughs） in the Dongting Lake area in China, where the farmland nitrogen application surpassed the average ecological fertilization dosage, is listed to the taxation scope of nitrogen fertilizer tax. The environment loss will reduce 0.07 hundred million RMB yuan and the revenue will increase 0.89 hundred million RMB yuan in the country after levying on nitrogen fertilizer. The loss, which was brought by the decreasing food supplies production, will be 0.58 hundred million RMB yuan and the net social benefit will be 0.38 hundred million RMB yuan following revenue collection. The variation scope of the increasing expenditure of farmers will range from 0.95 to 1.49%. The variation scope of the income of farmers will range from -8.41 to 6.44%. The 5 areas, Yunxi Borough, Junshan Borough, Hanshou County, Jinshi City, and Ziyang Borough, had an increase in food supplies production after the revenue collection. The environment loss will reduce 0.01 hundred million RMB yuan and the revenue will increase 0.16 hundred million RMB yuan in the country after levying on nitrogen fertilizer. The economic benefits, which was brought by the increasing cereals production, will be 0.67 hundred million RMB yuan and the net social benefit will be 0.84 hundred million RMB yuan after revenue collection. The variation scope of the increasing expenditure of farmers will range from 0.95 to 1.06%. The variation scope of the increasing income of farmers will range from 0.69 to 6.44%. Considering the entire social welfare, taxation of nitrogen fertilizer will have more advantages than disadvantages in the Dongting Lake area.展开更多

Methods: after the protocol design, 120 elderly diabetic pulmonary patients were included from January 2021 to December 2021, which were divided into 2 characters, with 60 cases in each group. The control group received the usual nursing intervention, and the observation group gave the empathy nursing intervention. Anxiety self-rating scale (SAS) and depression self-rating scale (SDS) were used. The SAS score, SDS score, cognitive score of pulmonary infection risk factors, respiratory care coordination, active activity coordination, and care satisfaction were compared between the two groups. Results: the SAS score (42.17 ± 4.26 vs 46.22 ± 5.02 points), the SDS score (41.28 ± 4.05 vs 45.20 ± 5.19 points) were lower than those in the control group, The cognitive score for the risk factors for pulmonary infection was higher than that in the control group (90.23 ± 8.56 vs 80.36 ± 9.40 points). Respiratory care coordination, active activities coordination, and nursing satisfaction were higher than those in the control group (95.00% vs 83.33%, 93.33% vs 80.00%, 95.00% vs 83.33%, P <0.05).Conclusion: empathy nursing is well applied in elderly patients with pulmonary infection, which can improve anxiety and depression, improve the cognitive level of pulmonary infection risk factors, and improve respiratory care, active activity coordination and nursing satisfaction.展开更多

Methods: the study was conducted according to the principle of grouping and control. The sample is 86 patients with osteoarthritis treated in our hospital. The period starts in April 2019 and ends in April 2021. They were randomly divided into observation group and control group, each with 43 samples. The control group was treated with triamcinolone acetonide, while the observation group was treated with sodium hyaluronate. The therapeutic effect was analyzed from the functional recovery of joints, long-term curative effect, short-term curative effect and probability index of occurrence rate of complications. Results: the analysis of joint function recovery showed that the observation group had obvious advantages over the control group (P < 0.05). Analysis of the long-term curative effect of the patients in the clinic shows that the observation group has a greater advantage than the control group (P < 0.05). The short-term curative effect of the observation group was significantly superior to that of the control group (P < 0.05). The probability of complications in the observation group was lower than that in the control group (P < 0.05). Conclusion: in the clinical treatment of osteoarthritis, sodium hyaluronate injection in the joint cavity has definite curative effect, which can significantly improve the joint function of patients and reduce the probability of complications such as lower limb fatigue, joint pain and swelling, blood pressure and blood glucose rise.展开更多

People have put forward different opinions on "what is education" from ancient times to the present. This paper considers "what is education" from the perspective of history teaching in middle schools, briefly describes the connotation and essence of education and history education, and puts forward the challenges that history education is facing and the problems that we need in history education. It provides some references for history education in promoting national identity and national identity.展开更多

Using SNPs each chromosomecan be divided into different haplotype blocks, and there arelimited common haplotypes in each block. This provides apowerful approach for whole genome scan for disease-asso-ciated genes/variants. However, most data available todayare based on the large-scale genomic analyses, data concern-ing individual genes for fine mapping with high density SNPsare relatively lacking. We have sequenced 7 genes and theirflanking regions, identified 34 novel SNPs, constructed highdensity SNP haplotypes and haplotype blocks in 5 genes inthe centromeric region of chromosome 15 in I00 ChineseHart subjects. Our results show that there is a great hetero-geneity in the haplotypes and haplotype block structureswithin and between these genes, which are in close physicalproximity. Data obtained in this study provide a useful toolfor candidate gene approach at the fine scale for identifyingdisease contributing variants in the genes/regions.展开更多
