Ventricular thrombosis and systemic embolism in bodybuilders: etiology and management

Increased thrombogenicity and acute embolism are well-recognized complications of chronic anabolic steroid abuse. The following cases highlight such dangers in steroid-enhanced bodybuilders who developed intracardiac thrombosis that subsequently embolized. Systemic anticoagulation and surgical thrombectomy constituted the mainstay treatment. This represents the first report of such devastating cardiovascular complications after anabolic steroid abuse and their management.

青光眼与颈椎病的眼部表现特点关系探讨

目的:对一组症状,体征表现极相似于青光眼但非青光眼所致的颈椎病患者进行分析诊断,并作治疗探讨。方法:我院1993/2003-10间一组症状相似的颈椎病患者37例,分析其症状及体征特征,并与青光眼相鉴别。结果:通过此组患者症状体征分析,提醒相关医师掌握这些知识,对此组患者进行正确诊断和治疗。结论:该组患者是一组特殊类型的眼科患者,可暂称其为缺血性视疲劳。     

Preparation and characterisation of the colistin-entrapped liposome driven by electrostatic interaction for intravenous administration

Potential use of liposome for polycationic colistin is hindered by their phospholipid membrane permeability. In this study, liposomes were modified with sodium cholesteryl sulphate (Chol-SO₄^?) for improving the colistin loading by enhancing the colistin-bilayer electrostatic attraction. We have evaluated two liposomes: colistin-entrapped liposome of Chol-SO₄^? (CCL) and coated Chol-SO₄^?/colistin complex liposome (CCCL). In comparison with CCL which formed large aggregates at Chol-SO₄^?/colistin charge ratio below 2:1, CCCL showed a smaller size less dependent on the charge ratio, probably arising from more colistin entrapped on the inner leaflet of bilayer. Both liposomes exhibited significantly increased entrapment efficiency as compared with the liposome without Chol-SO4^?. But colistin released upon dilution, implying free transfer of colistin through bilayers. Pharmacokinetics results showed the approximately four-fold increase in the plasma AUC_0–8?h for CCCL and CCL as compared with colistin solution, showing potential benefit for infectious target localisation by prolonging the systemic circulation of colistin.     

注射用牛肺表面活性剂治疗足月儿、近足月儿呼吸窘迫综合征的疗效分析

目的:探讨肺表面活性物质对足月儿、近足月儿呼吸窘迫综合征(NRDS)的疗效,为临床治疗提供依据。方法:收集我院新生儿科RDS患儿病历66份,根据是否使用肺表面活性物质分为治疗组和对照组,比较两组患儿治疗前的血气分析结果(pH值、二氧化碳分压、氧分压、呼吸频率)和用药1 h、6 h、12 h后两组患儿二氧化碳分压、呼吸频率和吸氧浓度,肺氧合功能(PaO2/FiO2、A-aPO2),比较两组患儿的吸氧时间、住院时间、呼吸机使用人数和死亡人数。结果:治疗前两组患儿血气分析各项结果之间比较差异无统计学意义(P>0.05);用药1 h、6 h、12 h后治疗组的二氧化碳分压、呼吸频率、吸氧浓度均小于对照组,两组之间比较差异有统计学意义(P<0.05或P<0.01),治疗组的肺氧合功能明显优于对照组(PaO2/FiO2治疗组高于对照组,A-aPO2治疗组低于对照组),两组之间比较差异有统计学意义(P<0.05或P<0.01),治疗组吸氧时间和住院时间明显短于对照组(P<0.01),治疗组呼吸机使用人数和死亡人数明显少于对照组(P<0.01)。结论:注射用牛肺表面活性剂对足月儿、近足月儿NRDS有明显的疗效,值得临床推广。
