上睑下垂的术前评估及改良提上睑肌缩短术矫治的疗效评价

目的评价改良提上睑肌缩短术矫治上睑下垂的效果。方法采用改良提上睑肌缩短术[此改良术式与常规术式不同之处在于增加分离提上睑肌腱膜的长度(22mm)和宽度(16mm),腱膜在睑板上固4对缝线,以增加其牢固度],共治疗上睑下垂57例68眼,其中轻度13例13眼,中度38例47眼,重度6例8眼。结果术后4～36个月随访,治愈48例59眼,欠矫9例9眼,无过矫病例。结论该提上睑肌缩短术与常规手术比较有改进,术后的睑缘高度易保持在上方角膜缘,弧度与健侧对称,不易形成眼角畸形,能较好提高矫治效果。     

Analysis of the circumstances at the end of life in children with cancer: Symptoms, suffering and acceptance

BACKGROUND: In an effort to improve the quality of life of children with cancer, this study analyzes the signs and symptoms at the end of life in such children. It is hoped that these data will contribute to the development of appropriate programs to address the challenges faced by these children. PROCEDURE: Between 1994 and 2000, 28 children died after treatment for cancer at Hamamatsu University Hospital, Japan. The circumstances, signs and symptoms at the end of life of these children were analyzed through their medical records. RESULTS: Of the 28 children, the underlying diseases were leukemia/lymphoma (LL group; n=11), brain tumors (BT group; n=7), and other solid tumors (OST group; n=10). Records showed poor appetite (100%), dyspnea (82.1%), pain (75.0%), fatigue (71.4%), nausea/vomiting (57.1%), constipation (46.4%) and diarrhea (21.4%) among these children. Anxiety was reported in 53.6% of the entire group of 28 children; however, no child in the BT group manifested anxiety. However, disturbance of consciousness was reported in all children in the BT group, which was significantly greater than in the other groups. Awareness, fear or acceptance of the imminence of his/her own death as indicated by verbal expression was reported in nine children (32.1%). CONCLUSIONS: Using the data obtained in the present study, we describe situations faced in the terminal care of children. It is important to address the problems revealed by this analysis in order to achieve improvements in both the physical and psychological care of children with terminal cancer.

Health-related quality of life and its predictive role for analgesic effect in patients with painful polyneuropathy.

Painful polyneuropathy is a common neuropathic pain condition. The present study describes health-related quality of life (HRQL) in a sample of patients with painful polyneuropathy of different origin and the possible predictive role of HRQL for analgesic effect. Ninety-three patients with a diagnosis of painful polyneuropathy were included in the analysis. Data were obtained from three randomised, placebo-controlled cross-over studies testing the effect of different drugs on polyneuropathic pain (St. John's wort, venlafaxine/imipramine and valproic acid). Patients completed a HRQL questionnaire (SF-36) after a drug-free baseline period and at the end of each treatment period. At baseline, all eight SF-36 scores were lower than in the normal population. No significant differences were found between SF-36 scales during placebo and treatment with valproic acid and St. John's wort. Those two drugs had not shown a pain relieving effect in former analysis. The SF-36 scale of bodily pain (BP) was improved by venlafaxine treatment (p=0.023). General health (GH) and vitality (VT) were improved under treatment with imipramine (GH: p=0.006, VT: p=0.015). In a multivariate logistic regression analysis, baseline SF-36 scores predicted subsequent response to pharmacological treatment. Results show an impaired HRQL in painful polyneuropathy and suggest that HRQL may predict response to analgesic treatment.     

Learning to Observe Relationships and Coping

Milieu relationships provide the critical background presence to staff's attempts to motivate, regulate, and teach patients how to cope with stress. Forging a connection with hospitalized children and adolescents demands attention to how they respond to adults and engage with staff around milieu expectations. Assessment guides that deal with these issues are presented. Important aspects of children's relatedness are presented in the context of their working models of adults and the influence of these representations on their response to staff. Coping skills are explained with particular emphasis on behavioral coping strategies. Tied to the assessment process are interventions that emphasize staff's role in helping patients manage strong affects and avoid the use of nonproductive behavior regulation strategies.     

Integrating Nursing Care into Systems of Care for Children with Emotional and Behavioral Disorders

PROBLEM: Recent developments in providing care to children with emotional and behavioral disorders, especially those with serious emotional disturbance, have included the establishment of systems of care. Guided by a set of principles and values, these systems of care have organized and delivered services to children and families with complex needs. To date, nurses have not had a salient role in systems of care. RESULTS: It is estimated that 20% of American children and adolescents have an emotional or mental disorder. As many as two thirds of these children are not receiving services. Systems of care have been funded to provide services for these children, particularly for the most severely affected. To date, nursing has not had a prominent role in these systems of care. CONCLUSIONS: Based on their knowledge, skills, and holistic approach to care, nurses could better integrate nursing care into systems of care. Possible roles as case managers, primary therapists, in-home interventionists, and in educational programs are suggested.

重组大鼠肝再生增强因子对急性肾衰竭大鼠肾脏的保护作用

目的 探讨重组大鼠肝再生增强因子(rrALR)对庆大霉素所致急性肾衰竭（ARF）大鼠肾小管上皮细胞及肾功能的保护作用。 方法 雌性Wistar大鼠150只，随机分成5组，每组30只，即健康对照组，ARF模型组，模型+空质粒对照组（空质粒组），模型+rrALR干预组（ALR组）：根据给予rrALR的剂量不同分为ALR1组和ALR2组两个亚组。分别于实验的第4、8、12、16和21天每组随机抽取6只大鼠在留取血、尿标本后，处死大鼠并取肾组织标本。常规生化方法检测各组大鼠BUN、Scr和尿N-乙酰-β-D-葡萄糖苷酶（NAG）酶的变化；PAS染色观察各组大鼠肾组织病理学改变；免疫组化法检测大鼠肾组织中ALR和增殖细胞核抗原（PCNA）的表达；Western印迹法检测肾组织中ALR蛋白的表达量。 结果 ARF大鼠各组BUN、Scr及尿NAG酶水平在第4、8、12、16天时均较对照组显著升高（P < 0.05）。与模型组和空质粒组相比，ALR组BUN、Scr及尿NAG酶水平明显降低（P < 0.05）；肾组织病理损害程度在各时间点明显减轻；而肾组织的ALR蛋白表达增加（P < 0.05）；肾小管上皮细胞增殖活跃；PCNA阳性细胞呈弥漫性分布，增殖指数（PI）明显升高（P < 0.05）。 结论 rrALR对急性损伤的肾小管上皮细胞具有减轻病变和促进再生修复的作用，可明显改善ARF大鼠的肾功能。
