ObjectiveTo understand the pre-hospital emergency medical staff's knowledge on crush injury and crush syndrome, and the influence of active and effective pre-hospital measures on the prognosis of patients with crush injury. MethodsWe retrospectively analyzed the clinical data of 51 patients with crush injury treated from September 2004 to August 2014, and recorded the number of cases in which pre-hospital emergency medical staff recognized and/or took effective measures to control crush syndrome. Treatment group included those patients who accepted effective prevention and control measures, and the rest of the patients were included in the control group. We compared the two groups of patients in terms of the incidence of serious complications such as crush syndrome and amputation. ResultsTwenty-five cases (49.0%) of crush injury were recognized before the patients were admitted into the hospital, among whom 20 (39.2%) accepted effective preventive and control measures. The mangled extremity severity score between the two groups of patients had no significant difference (6.69±1.96 vs. 7.23±3.54, P>0.05). After being admitted into the hospital, the treatment group had one complication case of crush injury, while the control group had 10 complication cases including 7 of crush injury and 3 of amputation. The complication rate of the treatment group (5.0%) was significantly lower than that of the control group (32.3%, P<0.05). ConclusionActive and effective prehospital preventive and control measures are very important in the treatment of crush syndrome and reduction of morbidity, but the pre-hospital emergency personnel's knowledge of crush injury and crush syndrome is not enough.
ObjectiveTo investigate the knowledge of hypoglycemia in patients with type 2 diabetes mellitus, analyze its influential factors, and explore the measure of hypoglycemia education. MethodsA questionnaire survey was conducted with a sample of 5 961 patients with type 2 diabetes mellitus from 144 hospitals in China between April and July 2010. The investigation contents included patients' demographic data and the knowledge of hypoglycemia. ResultsThe score of the knowledge of hypoglycemia was 62.71±10.34 and the status was medium. Multiple stepwise regression analysis showed that degree of education, duration of diabetes mellitus, periodic inspection, education about diabetic complications, times of hypoglycemia were influencing factors for the knowledge of hypoglycemia (P<0.05). ConclusionThe status of the knowledge of hypoglycemia is not optimistic. Educators should pay attention to the characteristics of patients and provide a safe regiment for controlling blood sugar with a comprehensive introduction of hypoglycemia.

Objective To investigate the status of knowledge, attitude and practice (KAP) of Standard Practice for Intravenous Nursing among nurses. Methods A total of 140 nurses were recruited and investigated with a self-designed questionnaire on March 16th, 2016. Results A total of 140 questionnaires were collected and 137 valid questionnaires were finally analyzed. Nurses’ KAP scores of Standard Practice for Intravenous Nursing were good. Hospital level, hospital characteristics, position and whether the nurses were specialized in intravenous nursing were influencing factors of the scores (P<0.05). Conclusions The general situation of KAP of Standard Practice for Intravenous Nursing is good, but nurses' knowledge on intravenous treatment is rather weak. Nurses should pay more attention to the knowledge of Standard Practice for Intravenous Nursing. Targeted education should be provided for nurses to promote the formation of positive attitude and healthy behaviors of clinical intravenous nursing practice.
Glaucoma is one of blind causing diseases. The cup-to-disc ratio is the main basis for glaucoma screening. Therefore, it is of great significance to precisely segment the optic cup and disc. In this article, an optic cup and disc segmentation model based on the linear attention and dual attention is proposed. Firstly, the region of interest is located and cropped according to the characteristics of the optic disc. Secondly, linear attention residual network-34 (ResNet-34) is introduced as a feature extraction network. Finally, channel and spatial dual attention weights are generated by the linear attention output features, which are used to calibrate feature map in the decoder to obtain the optic cup and disc segmentation image. Experimental results show that the intersection over union of the optic disc and cup in Retinal Image Dataset for Optic Nerve Head Segmentation (DRISHTI-GS) dataset are 0.962 3 and 0.856 4, respectively, and the intersection over union of the optic disc and cup in retinal image database for optic nerve evaluation (RIM-ONE-V3) are 0.956 3 and 0.784 4, respectively. The proposed model is better than the comparison algorithm and has certain medical value in the early screening of glaucoma. In addition, this article uses knowledge distillation technology to generate two smaller models, which is beneficial to apply the models to embedded device.

ObjectiveTo investigate the construction strategy of a knowledge base for health technology assessment (HTA) indicators based on a multi-granularity knowledge representation model, in order to meet the users' diverse demands for HTA knowledge services. MethodsFirstly, we constructed a multi-granularity HTA indicator knowledge representation model based on systematically analyzing the content and structure of the HTA indicator system in literature. Secondly, we extracted multi-granularity HTA indicator knowledge from literature and conduct subject indexing in a human-computer collaborative way. Finally, based on the HTA knowledge service requirements, a prototype of the HTA indicator knowledge base-HTA Indicators was designed and developed. ResultsA multi-granularity HTA indicator knowledge representation model was constructed, covering 5 core knowledge units (indicator systems, indicator items, formulas, measurement variables, and subjects), 20 types of attributes, and 12 types of relationships. This model represented the intrinsic characteristics and connections between multi-granularity indicator knowledge units. Knowledge extraction and subject indexing of multi-grain HTA indicators were conducted based on 227 HTA indicator documents, forming instance data. Finally, a prototype of the HTA indicator knowledge base, named HTA Indicators, was developed. HTA Indicators provides services such as multi-granularity HTA indicator knowledge retrieval, navigation, and linking. ConclusionThe construction strategy of the HTA indicator knowledge base based on the multi-granularity knowledge representation model is feasible. The indicator knowledge base can achieve multi-dimensional semantic organization of indicator knowledge, provide multi-level and multi-dimensional indicator knowledge retrieval and discovery services, and meet the users' demand for precise HTA knowledge. In the future, we will explore the use of cutting-edge technologies such as large language models to achieve the automated construction of large-scale HTA knowledge, thereby enhancing the efficiency and intelligence level of knowledge base construction.
ObjectiveTo understand the levels of and influencing factors for knowledge of earthquake in the elderly population. MethodPeople who were older than 60 years in the earthquake area of Sichuan Province were surveyed by self-designed earthquake knowledge scale composed of 6 items with a point of 1-5 for each item between October and November 2013. The total score ranged from 6 to 30 points. ResultsUp to 1 509 elderly people participated the survey. The total score of earthquake knowledge was 13.33±4.85. The main resource for acquiring those knowledge was TV (76.87%). Occupation, education level, residency, marital status, residence, self-injury, health status, access to earthquake knowledge, and worrying about earthquake were related factors for their knowledge on earthquake (P<0.05). Regression analysis showed that the higher degree of education, having a spouse, living in city, more access to earthquake knowledge, worrying about earthquake were the promotion factors for earthquake knowledge preparedness. Self-injury, poor health were the factors that hindered the acquiring of earthquake knowledge preparedness. ConclusionsIt is necessary to train knowledge of earthquake for elderly people individually because they lack enough resources and tend to be affected by many factors.
Objective To investigate the current status of self-management knowledge, attitude and behavior and influencing factors in patients with chronic obstructive pulmonary disease (COPD) in Qianbei area, and to analyze the influencing factors. Methods A total of 329 COPD patients were recruited and investigated with self-compiled questionnaire for self-management knowledge, attitude and behavior of chronic obstructive pulmonary disease, and SPSS 17.0 software was used to analyze the data. Results The mean score of self-management knowledge, attitude and behavior in COPD patients was 132.6±17.0, in which the scores of each dimension from high to low were as follows: smoking, medication treatment, exercise and family oxygen therapy. The analysis of stepwise regression indicated that the main influencing factors of self-management of COPD patients were age, sex, address, degree of education, course of disease and smoking. Conclusions The self-management level of the disease recognition, attitude and behavior in COPD patients should be improved, in which the knowledge is key factor to promote the health behavior of patients. So the healthy workers should pay close attention to the influence factors and apply the new thinking pattern and methods to improve the self-management ability and the quality of life of patients.
ObjectiveTo develop Knowledge attitude behavior and practice (KABP) health education path table, and to explore its application in health education of physician-nurse collaboration for children with epilepsy, and provide practical reference for health education of children with epilepsy.MethodsA convenient sampling method was used to select 94 family units of children with epilepsy and their main caregivers from the Department of Neurology in Hunan Children’s Hospital from September 2018 to March 2019. Divided into observation group and control group, 47 cases in each group. In the control group, the health care education was carried out by the conventional method of medical personnel’s one-way input of knowledge. The observation group conducted health education through interactive participation in the path of the health education path of KABP on the basis of regular health education. Then compared the effect of the health education between the two groups.ResultsAfter the intervention, the quality of life scores of the observation group were significantly higher than the control group (P<0.01). The relevant knowledge scores of main caregivers at 1 and 3 months after discharge were significant higher than those in the control group (P=0.008, P=0.001). The medication compliance scores of children with epilepsy at 1 and 3 months after discharge were significant higher than those in the control group (P=0.010, P=0.006).ConclusionsThe KABP health education pathway can improve the knowledge level of caregivers, as well as the medication compliance and quality of life of children with epilepsy.
