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。     

护理诊断应用现状与建议

现代化医院呼唤现代服务模式

当前我们正在向建设基本现代化医院迈进,在注意硬件建设的同时,不要忽略软件建设。硬件建设需要大量投入,较易见成果;而后者无需大量财力投入,只需转变医院人的思想观念,就能使医院明显改观。     

Duct-Islet Cell Tumor of the Pancreas. A Case Report with Immunohistochemical and Electron Microscopic Findings

A case of pancreatic tumor with features of both duct and islet cell components was found incidentally at autopsy in a 76 year old male who had died of intrahepatic cholan-giocarcinoma. The tumor, measuring about l.0cm in diameter, was located in the pancreatic tail. The tumor was composed of two distinct cell populations, islet cells and duct cells. Immunocytochemically, nearly all of the former cells were positive for insulin but negative for cytokeratin, carcinoembryonic antigen (CEA) and mucin, while the latter were positive for cytokeratin, CEA and mucin but negative for insulin. Additionally, a majority of the tumor cells that had formed islet-like structures were positive for neuron specific enolase (NSE), whereas NSE-positive cells were found only rarely in duct components. Electron microscopy confirmed the presence of two cell populations. Simultaneous occurrence of duct and islet cell components in a single pancreatic tumor indicates an intimate histogenetic relationship between pancreatic endocrine and duct cells.

教师心理健康影响因素探微

目的 从微观层面探讨归因、自我效能感、教育观念、人格因素对教师心理健康的影响。方法 使用《教师心理健康问卷》和CPSQ人格问卷》进行问卷调查。结果 能力和努力归因对教师心理健康有正向的预测作用；任务难度和运气归因对教师心理健康有负向的预测作用。工作效能和创造效能对教师心理健康都有正向的预测作用。成功教育、挫折教育和主动探索的教育观念对教师的心理健康都是正向的预测作用。神经质分数低的教师出现心理问题的几率不大；趋向于外向、开放、随和以及尽职尽责的教师，心理健康水平较高。结论 归因、自我效能感、教育观念、人格因素对教师心理健康都有程度不同的影响。     

Psychological and neuropsychological aspects of COPD

A review of the literature dealing with the effects of chronic obstructive pulmonary disease (COPD) on psychological and neuropsychological functioning indicates that significant emotional and adaptive deficits characterize this patient population. Psychiatric consultation can provide valuable assistance to the primary care physician by reducing emotional distress and correcting dysfunctional attitudes and beliefs. Neuropsychological assessment can elucidate an individual's neurobehavioral resources and deficits.     

Papain-induced lung injury: alterations in connective tissue metabolism without emphysema

The acute effects of the deposition of papain in the lungs of 4-month-old rabbits have been investigated with an amount not sufficient to cause emphysematous changes. During the first 2 days of in vivo deposition when hemorrhaging and inflammation occur, the total amounts of collagen and elastin in the lung, into which the papain had been instilled, did not change but the concentrations of collagen and elastin decreased 20 and 25% respectively. The rates of synthesis of collagen and other proteins doubled. By 4 weeks, collagen and elastin concentrations returned to, or were slightly above, control levels. The histological appearance and mean linear intercepts of lung sections and the compliance curves of excised lungs of the treated animals were similar to controls by 2 weeks after papain administration. The rabbit lung thus appears able to repair mild injury due to proteolytic enzymes.     

Glomerular matrix proteins in nodular glomerulosclerosis in association with light chain deposition disease and diabetes mellitus

The diagnosis of light chain deposition nephropathy is based on the immunohistochemical demonstration of monoclonal light chain deposits within connective tissue matrix and on the presence at the ultrastructural level of electron-dense granular deposits along glomerular and tubular basement membranes. A nodular glomerulopathy characterized by amorphous periodic acid-Schiff-positive and argyrophilic widened mesangium and nodules is described in three patients with light chain deposition nephropathy. Light microscopic examination did not allow discrimination between the glomerular changes found in these specimens and the nodular glomerulosclerosis described in four patients with well-documented diabetes mellitus. Electron microscopic examination revealed microtubular fibrils 10 to 12 nm thick in mesangial areas in both groups. Such microfibrils could be glycoproteins. Immunofluorescence localization of matrix proteins, by staining with affinity-purified antibodies to types I, III, IV, and V (A, B) collagens, fibronectin, laminin, and heparan sulfate-containing proteoglycans, showed similar distributions in the two conditions. The mechanism of this abnormal accumulation of mesangial and glomerular basement membrane matrix proteins in two different conditions remains unknown.
