25(OH)D水平对高血压合并冠心病患者心肌重构及左心室舒张功能的影响

目的分析25羟基维生素D[25(OH)D]水平对高血压合并冠心病患者心肌重构及左心室舒张功能的影响。方法选择80例高血压合并冠心病患者,根据左心室质量指数及左心室舒张功能分为心肌重构组和无心肌重构组、舒张功能障碍组和无舒张功能障碍组。Logistic回归分析影响高血压合并冠心病患者心肌重构及左心室舒张功能的独立危险因素,ROC曲线分析其诊断效能。结果与无心肌重构组比较,心肌重构组收缩压、总胆固醇(TC)、低密度脂蛋白胆固醇(LDLC)升高,25(OH)D降低(P＜0.05)。与无舒张功能障碍组比较,舒张功能障碍组体质指数(BMI)、25(OH)D水平降低,LDLC升高(P＜0.05)。25(OH)D是患者心肌重构及左心室舒张功能的危险因素(P＜0.05)。25(OH)D水平对患者心肌重构、舒张功能障碍有较好的诊断效能。结论25(OH)D水平是影响高血压合并冠心病患者心肌重构及左心室舒张功能的独立危险因素,早期检测其水平有助于临床诊疗。     

论情境模拟教学法在急诊教学中应用

急诊一般都是要求在尽量较短的时间内完成,对于一些实习的医生与护士来说,在实习的阶段内并不是每个人都能碰到相应的急诊案例,这对于急诊的教学带来了一定的难度,因而本文提出了情境模拟这一教学方法,应用于急诊的教学中以此提高急诊教学质量.     

改良皮下注射流程对低分子肝素钙患者抗血栓效果及并发症的影响

目的:探讨皮下注射流程改良对低分子肝素钙患者抗血栓效果及并发症的影响。方法:将130例低分子肝素钙抗血栓治疗的患者分为2组,观察组患者接受改良的低分子肝素钙皮下注射,对照组患者常规方法注射。治疗7 d后,比较患者血常规、凝血功能及血小板聚集功能、并发症发生率。结果:两组患者注射前后PT、APTT及ADP差异无统计学意义(P>0.05),患者皮下出血发生率、出血程度和硬结发生率比较,差异有统计学意义(P<0.05)。结论:改良皮下注射流程可降低患者并发症发生率,保障低分子肝素钙抗血栓效果。     

骨盆骨折伴出血介入术后的观察内容及护理

目的探讨严重骨盆骨折伴出血早期选择性血管内栓塞或结扎止血介入术后的临床观察及护理要点。方法本组共10例骨盆骨折伴出血采取早期选择性血管内栓塞或结扎止血介入术后患者，对其进行严密观察及护理。结果10例患者全部抢救成功。结论严重骨盆骨折造成早期死亡原因主要是合并大出血所致休克。而该术式方法简单、迅速、安全、创伤小、痛苦少，能保留脏器功能，严重休克患者在积极输液输血抗休克的同时也能耐受此手术，并能有效缩短休克期。

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.

目的　观察弹性绷带在乳腺癌术后应用效果。方法　 4 8例乳腺癌根治术后应用弹性绷带包扎为实验组 ,4 5例用普通宽绷带包扎为对照组。然后 ,对两组患者术后并发症进行观察。结果　实验组患者的并发症明显低于对照组 ,两组比较有显著性差异 ,P <0 .0 5。结论　应用弹性绷带包扎 ,能明显减少并发症的发生 ,促进切口愈合 ,使患者术后术侧上肢功能锻炼可以提早进行。     

六点十分的爱

几年前,一位刚毕业的女孩打电话给父母,说她要去深圳一家外企应聘,并无意中提起中途会经过父母所在城市的一个小站。那个小站的邻县,距离她父母所在城市有两个小时的车程。列车停靠那个小站时是早晨6时10分,停靠时间大约10分钟。车刚停稳,女孩子隐约听到有人呼唤她的名字,她探身窗外在朦胧的曙色中看到了父母的身影。母亲急急忙忙把用手巾包着的一个瓷缸递给她,揭开盖子,是热气腾腾的肉饼汤。短暂的10分钟里,她父母几乎不容她说什么,只是那样满足、幸福地催促她一口口喝汤。天凉,汤冷得快。列车开动时,女孩父母提着一个空瓷缸站在月台上向女孩挥手,
