鼻唇沟透明质酸注射填充术:应用钝针与锐针安全性和有效性的比较

目的对比应用钝针与锐针对鼻唇沟行透明质酸注射填充的安全性和有效性。方法自2015年5月至2016年10月,应用透明质酸对60例鼻唇沟凹陷求美者行鼻唇沟注射填充。随机分为两组,每组30例求美者。钝针组应用27 G钝针进行注射,锐针组应用27 G锐针进行注射。观察两组临床效果、维持时间及并发症发生情况。结果本组求美者获随访1～9个月,两组修复效果均较明显,两组总有效率差异无统计学意义(P0.05);局部肿胀发生率钝针组高于锐针组(P0.05);淤青、局部不平整和丁达尔现象的发生率锐针组高于钝针组(P0.05)。结论通过透明质酸注射填充可以安全、有效地修复鼻唇沟凹陷,锐针注射可以对皮肤表面形态进行更精细的雕刻,钝针注射更有利于降低血管栓塞等相关并发症的发生风险。     

一见室速就紧张?缓急有别处理攻略

室性心动过速(室速)是风险较高的心律失常,可与室颤及猝死相关.然而,并不是所有的室速均需高度紧张,立即处理.例如,多形性室速风险极高,需要立即电复律;相反,单形的非持续性室速甚至可见于正常人.本文拟结合今年8月发布的《室性心律失常中国专家共识》以及2014年欧洲EHRA/HRS/APHRS《室性心律失常专家共识》,谈谈遇到室速,如何做到「缓急有别,妥善处理」.     

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.

输液配制中微粒产生原因与后果

<正> 随着大输液治疗用量的扩大和临床的广泛应用,质量要求愈加严格,其中重要指标之一是不溶性微粒的限量必须符合规定。大输液微粒系指来自生产使用过程中由多种途径污染的肉眼难以发现的微小颗粒杂质(肉眼可以见到50μm 以上者通常称为异物)。它不溶于水,在人体内亦不被代谢。按生产要求,澄明度检查不可能发现,这种微小颗

从海南萝芙木生产“降压灵”的母液中,分得一新的二聚体生物碱,命名为大斯配加春(macrospegatrine)。根据红外、紫外、质谱、氢谱及单晶X—射线衍射确定结构为Ⅰ式(图1)。     

脊髓血管畸形血管内皮生长因子在脑脊液的表达

目的探讨脊髓血管畸形是否存在血管内皮生长因子(VEGF)表达,及其表达与临床特征之间是否存在相关性。方法在手术中留取56例脊髓血管畸形的脑脊液标本,其中动静脉畸形(SCAVM)23例,硬脊膜动静脉瘘(SDAVF)19例,海绵状血管瘤(CM)14例;以我院12例蛛网膜下腔阻滞病人脑脊液作为对照组,分别通过酶联免疫吸附方法(ELISA)测定脊髓血管畸形脑脊液中VEGF含量。结果SCAVM脑脊液中VEGF浓度为(277±66)pg/ml、SDAVF为(318±54)pg/ml、CM为(146±32)pg/ml均高于正常对照组(123±27)pg/ml。术前栓塞和出血均可导致脑脊液VEGF升高。结论VEGF与脊髓血管畸形的发生、发展存在一定关系,出血和栓塞均可影响VEGF的表达。
