Kindergarten children's representation and understanding of written number symbols

Two samples of kindergarten children's representation and understanding of written number symbols were examined in two time points in one academic year. About 85% of Chinese five year olds (mean = 5 years 10 months) were able to use conventional number symbols to represent the quantity of 30 or larger. At the end of the kindergarten year, 94% of Chinese six year olds (mean = 6 years 4 months) were able to use conventional number symbols to represent the quantity of 100 or larger. Some Chinese six year olds had problems in representing written addition and subtraction tasks. Children's ability to represent written number symbols, ability to represent written addition and subtraction formula and their performance on written addition and subtraction were closely related. The performance of children in a university-affiliated childcare center was better than that of the center serving working-class families in Time 1, but the performance reversed at the end of the kindergarten year.     

Reconstruction of a transmetatarsal amputation stump using a salvaged peroneal artery fasciocutaneous flap from the opposite leg: A case report

During lower extremity amputation, the objective is to provide a functional residual limb that permits maximum patient mobility and independence. Preservation of length of the fore part of the foot using salvageable tissue from the amputated part in young patients prevents equines deformity and revision of amputation to a higher level. This can be achieved using tissue available from the amputated part. The spare part concept in reconstructive surgery should be integrated into the trauma algorithm to avoid additional donor site morbidity. Reported here is a young adult patient with crush injuries to both feet, which resulted in amputations. A fasciocutaneous flap raised from one extremity was used to facilitate transmetatarsal amputation stump length preservation of the other extremity.     

医疗卫生服务价格改革方向初探

医疗卫生服务价格改革是要理顺价格构成成份之间量的关系，使每个构成成份的价格值都在供求关系的约束中，在政府的有效管制中，从而成为医疗卫生资源合理配置的有效工具。为此：①对生产要素分别定价；②对劳动定价；③对资本和自然资源定价；④确定医疗卫生机构内部管理时劳动价格；⑤价格中的所有构成成份价格都置于供给和需求关系约束下；⑥确定医疗卫生服务价格的理想传递方式。     

高中生自我和谐与应对方式及其相互关系

目的了解高中生自我和谐、应对方式的特征及其相互关系,为开展心理健康教育提供依据。方法采用自我和谐量表及简易应对方式问卷,对755名高中生进行问卷调查。结果高中生总分和各因子分在性别、是否独生子女、城乡、文理科等方面差异均无统计学意义,自我和谐总分存在年级差异;积极应对和消极应对维度在性别、是否独生子女、城乡、文理科等方面差异均无统计学意义,消极应对维度存在年级差异。应对方式与自我和谐总分及分量表得分存在不同程度的相关。结论采用积极应对方式有助于促进高中生的自我和谐,而消极应对方式对自我和谐存在不利影响。

The concept of self-management of type 1 diabetes in children and adolescents: an evolutionary concept analysis

AIM: An evolutionary concept analysis was undertaken to clarify the concept of self-management of type 1 diabetes in children and adolescents. BACKGROUND: Several problems exist in the literature on self-management of type 1 diabetes in children and adolescents. There is no uniform terminology and there is no uniform definition of the concept. Also, there is no differentiation in the literature between self-management of diabetes in children and adults. METHODS: Ninety-nine references were reviewed and analysed in the disciplines of nursing, medicine, and psychology. After separate analyses revealed no significant differences across disciplines, the analyses were combined to describe the attributes, antecedents, consequences, and surrogate and related concepts. RESULTS: The three essential attributes of the concept were identified as process, activities, and goals. Self-management of type 1 diabetes in children and adolescents is an active and proactive process; it is daily, lifelong, and flexible, and it involves shifting and shared responsibility for diabetes care tasks and decision-making between child and parent. It is a process that involves collaboration with health care providers. Self-management of type 1 diabetes in children and adolescents also consists of varied and many activities related to giving insulin, monitoring metabolic control, regulating diet and exercise, to name just a few. The concept also involves goals, which may differ from one parent/child dyad to another. A working definition of the concept is suggested. CONCLUSIONS: It is hoped that a more uniform definition of the concept will enable researchers to continue investigating antecedents and consequences of the concept in a way that allows for aggregating results.     

Efficacy of continuous subcutaneous insulin infusion in Type 1 diabetes: a 2-year perspective using the established criteria for funding from a National Health Service.

AIM: To determine the 2-year efficacy of continuous subcutaneous insulin infusion (CSII) following the current established criteria for funding of a National Health Service. METHODS: Longitudinal, prospective, observational unicentre study. Included in the study were 153 Type 1 diabetes (T1D) subjects, previously treated with multiple daily injections (MDI) of insulin, in whom CSII was started in accordance with the criteria for reimbursement of the Catalan National Health Service. At baseline, we recorded data on age, gender, duration of the disease, body mass index (BMI), insulin dose and indications for CSII. Glycated haemoglobin (HbA(1c)) and the frequency of hypoglycaemic events were used to assess glycaemic control. Quality of life was assessed using three different self-report questionnaires. After 24 months, these same items were remeasured in all subjects. Serious adverse events and injection-site complications were also recorded. RESULTS: In 96% of subjects, CSII indication included less than optimal glycaemic control using MDI. HbA(1c) fell from 7.9 +/- 1.3 to 7.3 +/- 1.1% (P < or = 0.001) after 24 months of CSII. Insulin requirements were significantly lower at the end of follow-up (0.55 +/- 0.21 U/kg body weight) in comparison with before use of CSII (0.70 +/- 0.20, P < or = 0.001). BMI increased from 24.0 +/- 3.1 to 24.4 +/- 3.2 kg/m(2) after 24 months (P < or = 0.025). The rate of episodes of diabetic ketoacidosis per year remained unchanged. Mild and severe hypoglycaemic episodes were significantly reduced. The scores in all subsets of the Diabetes Quality-of-Life (DQoL) questionnaire significantly improved after 24 months of CSII. CONCLUSIONS: CSII, commenced according to the criteria for a nationally funded clinical programme, improves glycaemic control and quality-of-life outcomes with fewer hypoglycaemic episodes in T1D subjects previously conventionally treated with MDI.     

再论医院后勤服务社会化的可行性

目前，经济高速发展，服务体系和水准相对滞后，加上管理者素质的提高，现代管理技术的应用，以及后勤管理体制的改革，为医院后勤工作向社会分离提供了条件，也为推进医院后勤服务社会化提供了机遇。但规范卫生服务市场体系是后勤服务社会化的保障，故要建立：卫生物质流通、后勤人才流动、经济信息市场及卫生建设筹资机构。在推进后勤服务社会化时尚需解决：①支持条件；②实施集团联盟；③注意经营定位等问题。
