Methods: a total of 114 elderly patients with hypertension were selected from June 2021 to June 2022. Each sample was randomly divided into intervention group and reference group. The sample size involved in each group was 57 cases. The former received clinical nursing intervention, while the latter received traditional nursing to monitor blood pressure indicators, observe negative emotions, investigate hypertension knowledge and assess self-management ability. Results: before the intervention, the diastolic pressure and systolic pressure of each group were monitored, and the above data were tested. There was no significance between the intervention group and the reference group (P>0.05). After the intervention, the diastolic pressure and systolic pressure of each group were monitored, and the above data were tested, which was lower in the intervention group than in the reference group (P<0.05). Before the intervention, the SDS and SAS indexes of the samples in each group were monitored and tested against the above data, which had no significance between the intervention group and the reference group (P>0.05). After the intervention, the SDS and SAS indexes of the samples in each group were monitored and tested against the above data, which was lower in the intervention group than in the reference group, i.e. the intervention group had less negative emotions (P<0.05). The excellent and good rate of hypertension knowledge of each group sample was assessed and counted, which was 92.98% in the intervention group and 77.19% higher than that in the reference group after the test, P<0.05. The self-management ability of each group was evaluated through medication, diet, monitoring, exercise, emotion and other dimensions, and the scores obtained were tested, which were significantly different in the intervention group, which was higher than the reference group (P<0.05). Conclusion: clinical nursing intervention can be popularized, which can quickly stabilize blood pressure and improve the emotion of the elderly, and can also enable the elderly to understand the knowledge of hypertension and maintain high self-management ability. 展开更多

本研究以干法预处理前后的甘蔗渣纤维素为原料,通过乙酰化(均相)与苯甲酰化(非均相)反应,分别制备得到不同预处理时间下的醋酸纤维素(SBC-CA、Pre-SBC1-CA、Pre-SBC2-CA)和苯甲酸纤维素(SBC-CB、Pre-SBC1-CB、Pre-SBC2-CB),并对其进行表... 本研究以干法预处理前后的甘蔗渣纤维素为原料,通过乙酰化(均相)与苯甲酰化(非均相)反应,分别制备得到不同预处理时间下的醋酸纤维素(SBC-CA、Pre-SBC1-CA、Pre-SBC2-CA)和苯甲酸纤维素(SBC-CB、Pre-SBC1-CB、Pre-SBC2-CB),并对其进行表征,探讨干法预处理对甘蔗渣纤维素酯化反应活性与产物结构、性能的影响。结果表明,干法预处理有效提高了甘蔗渣纤维素的酯化反应活性,且有利于制备具有良好结晶结构、疏水性能和热稳定性的醋酸纤维素与苯甲酸纤维素。分别与未经干法预处理的SBC-CA和SBC-CB相比,经干法预处理3 h后进一步制得的Pre-SBC2-CA与Pre-SBC2-CB的酯化反应活性效率最佳,取代度分别为2.82、0.76,提高了20.5%、46.2%,产率增大1.2和1.3倍;结晶度指数提高1.26和1.09倍,水接触角增大74.1%和20.5%,最大分解速率对应温度高达380和369℃,初始分解温度与完全分解温度同步提高。 展开更多
