为提高核桃壳仁混合物的分级效果，对现有核桃壳仁混合物分级设备进行三维实体建模，利用EDEM软件模拟核桃壳仁混合物的分级过程，以筛面上物料的运动速度、质量以及各等级颗粒在统计区域的数量为指标，以振幅、振动频率、振动方向角、筛面倾角为考察因素，对振动筛分级工艺进行优化。结果表明：在振动频率12 Hz、振幅5 mm、振动方向角45°、筛面倾角4°的工艺参数组合下，各等级核桃壳仁的透筛率最高，分级效果最好。In order to improve the grading effect of walnut shell and kernel mixture, the existing classification equipment of walnut shell and kernel mixture was modeled by 3D entity, and the grading process of the walnut shell and kernel mixture was simulated by EDEM. Based on the movement speed, mass of the material on the sieve surface and quantity of particles of each grade material in the statistical area as indicators, the grading process by vibrating screen was optimized with the amplitude, vibration frequency, vibrating direction angle and the sieve surface inclination as factors. The results showed that the screening rate of each grade of walnut shell and kernel was the highest and the grading effect was the best under the conditions of vibration frequency 12 Hz, amplitude 5 mm, vibrating direction angle 45°, and sieve surface inclination 4°.

Objective To investigate the effect of continuity of care based on enhanced self-management for patients with early diabetic nephropathy. Methods Totally 54 patients with early diabetic nephropathy were randomly divided into the control group and observation group, with 27 cases in each group. All patients received integrated traditional Chinese and western treatment at outpatient visit. Patients in the control group received routine nursing interventions after discharge from the hospital, and those in the observation group were given continuity of care interventions based on enhanced self-management. The clinical outcome indexes were measured before and 6 months after intervention. Results Better clinical outcomes were observed at 6 months after intervention, and systolic pressure, urinary albumin creatinine ratio(UCAR), uric acid, fasting blood-glucose and glycosylated hemoglobin of patients in the observation were significantly lower than those in the control group, respectively(P＜0. 05). Conclusion Continuity of care based on enhanced self-management is potentially effective to reduce the systolic pressure, UCAR), uric acid, fasting blood-glucose and glycosylated hemoglobin of patients with early diabetic nephropathy. (目的 探讨强化自我管理的延续性护理模式在早期糖尿病肾病患者中的应用效果。方法 采用简单随机数字表法将符合纳入标准的54例早期糖尿病肾病患者随机分为对照组和观察组, 各27例。两组患者均接受中西医结合门诊治疗, 对照组采用常规院外护理措施, 观察组在入组当日即采用强化自我管理的延续性护理模式。分别在干预前和干预6月时收集两组患者生化指标并进行比较。结果 干预6个月时, 两组患者各项指标较干预前有下降趋势, 与对照组比较, 观察组较收缩压、尿微量白蛋白与尿肌酐比值(UACR)、血尿酸、空腹血糖及糖化血红蛋白指标更低, 改善更明显, 差异有统计学意义(P＜0. 05)。结论 强化自我管理的延续性护理模式能有效降低早期糖尿病肾病患者收缩压、UACR, 血尿酸、空腹血糖及糖化血红蛋白, 值得借鉴。)

Objective To investigate the knowledge about health education and self-management behavior in patients with early diabetic nephropathy, and provide reference for establishment of targeted health education and nursing plan. Methods A convenience sample of 118 patients with early diabetic nephropathy was enrolled. The general information, patients’ knowledge about health education and their self-management behavior were assessed by self-made Knowledge Assessment Scale and the Summary of Diabetes Self-Care Activities Measure(SDSCA). Results The average score of lifestyle dimension of Knowledge Assessment Scale was (2. 58±0. 59), and the lowest score was reported in diet sub-dimension(2. 29±0. 56), followed by exercise(2. 59±0. 69), stopping smoking (2. 96±0. 88) , stopping alcohol (3. 17±0. 95)and bodyweight control (3. 33±0. 93). The average score of medication management dimension was (3. 11±0. 65), and average score of symptoms observation and nursing practice was (2. 55±0. 73)and (2. 55±0. 89), respectively. The average score of social-psychological nursing and follow-up management was (3. 28±0. 60)and (3. 28±0. 60), respectively. The score of each dimension of SDSCA was listed as follows: diet (3. 39±1. 30), exercise (4. 05±2. 85), blood sugar monitoring(1. 14±1. 82), medication adherence(4. 20±2. 30)and foot care(1. 87±2. 47). There were 39(33. 05%)smokers who consumed averaged 19. 01 cigarettes per day. Conclusion Patients with early diabetic nephropathy had poor knowledge about health education, practically in knowledge about diet and exercise. Efforts should be made to enhance the health education on knowledge about prevention and treatment of early diabetic nephropathy. In addition, the poor self-management behavior among patients with early diabetic nephropathy may indicate poor diabetes self-management as a negative influencing factor of progression of early diabetic nephropathy. (目的 探讨早期糖尿病肾病患者健康教育知识水平及自我管理行为现状, 为制定针对性的健康教育及护理方案提供依据。方法 采用便利抽样方法对纳入某三级甲等中医院符合纳入排除标准的118例早期糖尿病肾病患者实施调查, 调查内容包括患者一般资料、自编的早期糖尿病肾病相关知识知晓情况调查表、糖尿病自我管理活动问卷(SDSCA), 并对数据资料进行描述性统计分析。结果 早期糖尿病肾病患者健康教育知识水平调查结果显示, 生活方式平均得分(2. 58±0. 59)分, 其中饮食(2. 29±0. 56)分、运动(2. 59±0. 69)分、戒烟(2. 96±0. 88)分、戒酒(3. 17±0. 95)分、体质量控制(3. 33±0. 93)分; 用药管理平均得分(3. 11±0. 65)分, 症状观察(2. 55±0. 73)分, 护理操作技巧(2. 55±0. 89)分; 社会心理护理(3. 28±0. 60)分, 复诊管理(3. 24±0. 96)分; SDSCA量表的各维度中得分为饮食(3. 39±1. 30)分、运动(4. 05±2. 85)分、血糖监测(1. 14±1. 82)分、遵医用药(4. 20±2. 30)分和足部护理(1. 87±2. 47)分。39(33. 05%)人吸烟, 平均每日吸烟19. 01支。结论 早期糖尿病患者的健康教育知识水平知晓情况较差, 尤其是生活方式中的饮食及运动方面, 早期糖尿病肾病防治的相关知识的宣传教育和科普亟待加强; 此外, 早期糖尿病肾病患者的自我管理行为也较差, 可能进一步验证了不良的糖尿病自我管理是早期糖尿病肾病疾病进展的重要因素。)

Taking the households of urban and rural residents in Zhejiang Province as the research object in 2020, an indicator system for rural development and urbanization is constructed from the four aspects of ecological environment, public services, grassroots governance and quality of life, using entropy method and Coupling Coordination Degree Model, Theil index and other methods to summarize the urban-rural development experience and problems of different counties and cities in Zhejiang Province, and explore the urban-rural coupling mode and implementation path. The results show that: ①Based on the analysis of different spatial scales, the urbanization and rural have regional imbalances in development, with obvious gradient changes from east to west and little difference between sub-regions. About 80% of the overall difference in urban-rural development in Zhejiang comes from differences within sub-regions, and another 60% comes from the internal differences between southwestern Zhejiang and southern Zhejiang. At the county level, the urbanization and rural development index presents a spatial pattern of "high in the northeast and low in the southwest". ②Based on the analysis of the degree of urban- rural coupling and coordination in Zhejiang Province, four urban-rural coupling modes are summarized: independent parallel coupling, urban-rural partial benefit interactive coupling, urban-rural symmetrical reciprocal coupling, and urban-rural integration symbiosis coupling. ③ Based on the rural revitalization strategy, the implementation path summarized from ecological livability, public services, grassroots governance and quality of life is characterized by ecological integration, green development, spatial integration, shared development, governance integration, good rural governance, factor integration, and common prosperity.
