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.

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.

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.

Cotton bud is one of the most important cash crops with many uses, such as the textile and cotton fabric raw material. However, manual cotton topping cannot fully meet the large-scale production in recent years, due to the efficiency and labor costs. Intelligent mechanical topping can be expected to serve as an inevitable trend during cotton topping. There is a high demand to accurately identify the cotton top bud under the complex environment (such as light and shadow), particularly for the various shape characteristics of cotton top core in the process of cotton cap removal. In this study the accurate recognition was proposed to locate the cotton top bud in the complex environment using an improved YOLOv5s. A dataset was also constructed to contain 3103 cotton top buds with different morphological characteristics under a complex environment. Three categories were divided: single, multi-plant and screened top bud under different occlusion areas, weather and light conditions. Systematic training and analysis were then performed on the data. An improved YOLOv5s model was proposed to reduce the error and leakage detection for the sufficient features of small targets. Multi-scale target features were also effectively extracted using only three detection heads in the original YOLOv5s. At the same time, the ideal extraction of the improved YOLOv5s was obtained with the deepening of the network layer. The object detection and CPP-CBAM attention mechanism were first added to the original structure, in order to improve the shallow and deep feature fusion rate. Secondly, the regression of prediction frame was enhanced to avoid the information loss of the real frame. The loss function SIOU boundary frame regression was added to further accelerate the prediction frame regression speed for the detection accuracy. The SIOU loss function was introduced by the vector angle between the real and predicted frame including angle, distance, and shape loss function. As such, the aspect ratio between the predicted and real frame was considered in the CIOU loss function with the direction between them in the SIOU. The high accuracy of recognition rate was obtained on the top bud, resulting in the less degrading into an IOU loss function. In addition, an accurate identification was performed on the cotton top bud that was seriously obscured by the leaves. The results show that the average accuracy (mAP) reached 92.8% for the recognition of cotton top bud by the improved model. Furthermore, the average accuracy was improved by 2.1, 3.3, 2, and 2.4 percentage points, respectively, compared with Fast R-CNN, YOLOv3, YOLOv5s, and YOLOv6. The improved detection model can be expected to accurately and efficiently identify the cotton top bud under a complex environment in real time. The small size of the model parameters and the high identification speed were suitable for the migration deployment of cotton topping machinery, and the operation of the laser topping robot. The finding can also provide technical and theoretical support to the subsequent operation of cotton laser topping machines, particularly for the mechanized real-time topping. [ABSTRACT FROM AUTHOR]
