目的:探讨低分子量肝素对进展型脑梗死的疗效及血流变影响.方法:将80例进展型脑梗死患者,随机分为治疗组40例,对照组40例.两组在治疗前后均行神经功能缺损评分和临床疗效评定,并观察其疗效及有关实验室指标,追踪随访1年.结果:治疗组的有效率明显高于对照组,不良反应轻微,PLT、APTT无明显变化,但血流变指标明显下降,1年内复发率明显小于对照组.结论:低分子肝素治疗进展型脑梗死疗效肯定,对于减少复发亦有一定作用,并可改善血流变.     

Traumatic diaphragmatic rupture: associated injuries and outcome

A retrospective case note analysis was performed on all patients treated for traumatic diaphragmatic rupture (TDR) at a major teaching hospital between January 1990 and August 1998. Patients were identified from the prospectively maintained UK Trauma and Research Network Database. Of the 480 cases of torso trauma admitted during the study period, 16 (3.3%) had TDR. Blunt trauma accounted for 13 (81%) of the injuries. A radiological pre-operative diagnosis was made in 10 (62.5%) patients. Seven of these were made on initial chest radiography, two on ultrasound scan and one on computed tomography. All patients underwent a midline laparotomy and TDR was subsequently diagnosed at operation in 6 patients. The left hemidiaphragm was ruptured in 14 (87.5%) patients and there was visceral herniation in 8 (50%). Twelve patients with blunt trauma had associated abdominal and extra-abdominal injuries, but only one of the three patients with penetrating trauma had other injuries. The median Injury Severity Score (range) was 21 (9-50). The median time (range) spent on the intensive care unit was 2 days (0-35 days). Pulmonary complications occurred in 7 (44%) patients. Two (12.5%) patients died from associated head injuries. TDR results from blunt and penetrating torso trauma, is uncommon, rarely occurs in isolation and is associated with a high morbidity and mortality. A high index of suspicion makes early diagnosis more likely as initial physical and radiological signs may be lacking.     

采用结构-过程-结果三维质量评价模式实施CABG延续护理实践

  目的  探讨基于结构-过程-结果的三维质量评价模式的延续性护理在冠状动脉旁路移植术（coronary artery bypass grafting，CABG）患者中的应用效果。  方法  选取2018年8月至2019年12月收治昆明市延安医院心脏大血管外科行CABG围术期的168例患者为研究对象，采用随机数字表法分成两组，每组各84例，对照组实施常规延续护理，干预组实施基于结构-过程-结果三维质量评估模式构建的延续性护理方案，干预后比较两组患者《中国心血管病人生活质量评定问卷》（CCQQ）评分、服药依从性评分、主要心脑血管事件（MACCE）发生率。  结果  干预组《中国心血管病人生活质量评定问卷》（CCQQ）评分、服药依从性评分、主要心脑血管事件（MACCE）发生率均高于对照组，差异有统计学意义（P < 0.05）。  结论  Donabedian的结构-过程-结果延续性护理三维质量评价模式构建有助于提高CABG术后患者自我管理效能感及生活质量，是提升延续性护理质量的有效途径。     

滇龙胆草对肺纤维化小鼠肺组织NF-κB和CTGF表达的影响

  目的  研究滇龙胆草对肺纤维化小鼠肺组织NF-κB和CTGF表达的影响。  方法  气管滴注博莱霉素（5 mg/kg ）制备昆明小鼠肺纤维化模型，造模后灌胃给予低、中、高剂量（50、100、200 mg/kg）的滇龙胆草，每日给药1次，设比非尼酮为阳性对照。在建模后第28天，取肺组织进行检测，肉眼观察肺组织大体病理改变，Masson染色观察肺组织纤维化程度；采用Western blot检测肺组织中NF-κB和CTGF蛋白的表达。  结果  与模型组比较，不同剂量的滇龙胆草组和阳性药物比非尼酮组小鼠肺组织胶原沉积明显减少。与模型组比较，不同剂量的滇龙胆草组和阳性药物比非尼酮组小鼠肺组织NF-κB和CTGF蛋白表达明显下调，差异有统计学意义（P < 0.05）。  结论  滇龙胆草具有抗肺纤维化作用，其机制与下调NF-κB和CTGF蛋白表达，减轻肺组织炎症和胶原沉积有关。     

Revisión de las terapias biológicas en la enfermedad inmunomediada del oído interno

Introduction and objectivesImmune-mediated inner ear disease (IMIED) is one of the few reversible forms of sensorineural hearing loss. Treatment is based on high-dose corticosteroids, although long-term therapy is associated with serious adverse effects; this has led to the use of other agents or different routes of administration such as transtympanic delivery. This study analyses the role of biological agents in IMIED management.Material and methodsWe searched PUBMED for studies that examined the response to treatment with different biological agents in patients with IMIED. The following data were extracted from the selected studies and entered into a standardised database: exclusion and inclusion criteria, characteristics of the patients studied, treatment, outcome measures and response rates achieved.ResultsThirteen studies were included in this review. A TNF alpha inhibitor (etanercept, infliximab, adalimumab) was used in 8 studies, an IL-1 antagonist (anakinra) was used in 3 studies and rituximab, an antibody directed against the CD20 surface antigen on B lymphocytes, was evaluated in 2 studies. Most studies achieved a hearing improvement or stabilisation in more than 70% of treated patients.ConclusionsBiological agents can play a role in the management of patients with IMIED, at least in those patients who do not respond to conventional therapy or whose hearing is not stabilised. However, specially-designed randomised controlled clinical trials are needed to assess their effectiveness.     

Involvement of autophagy in melatonin‐induced cytotoxicity in glioma‐initiating cells

Glioblastoma‐initiating cells (GICs) represent a stem cell‐like subpopulation within malignant glioblastomas responsible for tumor development, progression, therapeutic resistance, and tumor relapse. Thus, eradication of this subpopulation is essential to achieve stable, long‐lasting remission. We have previously reported that melatonin decreases cell proliferation of glioblastoma cells both in vitro and in vivo and synergistically increases effectiveness of drugs in glioblastoma cells and also in GICs. In this study, we evaluated the effect of the indolamine alone in GICs and found that melatonin treatment reduces GICs proliferation and induces a decrease in self‐renewal and clonogenic ability accompanied by a reduction in the expression of stem cell markers. Moreover, our results also indicate that melatonin treatment, by modulating stem cell properties, induces cell death with ultrastructural features of autophagy. Thus, data reported here reinforce the therapeutic potential of melatonin as a treatment of malignant glioblastoma both by inhibiting tumor bulk proliferation or killing GICs, and simultaneously enhancing the effect of chemotherapy.
