STUDY OF MORPHOLOGICAL CHANGES OF HEART IN VIRAL MYOCARDITIS CAUSED BY REPETITIVE INFECTION OF CVB3m

Objective To investigate the morphological changes of heart in viral myocarditis caused by repetitive infection of CVB3m. Methods 4-week-old mice were infected four times intraperitoneally with a timedependent dose and killed at the 10th, 30th and 60th day after the final infection respectively, then we examined the heart changes and collagen hyperplasia by HE, VG stain and 1HC. Results Heart damage appeared very serious at the tenth day, even there were small necrotic foci at the day of 30th, but we could not see any injury of heart 2 months later after final infection. Collagen turned up at the tenth day and there was much more collagen in heart and increased PCVA, CVF index at the sixtieth day. The 1HC of collagen demonstrated the collagen I hyperplasia was much obvious compared to collagen Ⅲ. Conclusion It strongly indicated that repetitive infection of CVB3m could lead to heart fibrosis and ventricular remodeling, which resulted in decreased systolic and diastolic function of heart.     

肝脏炎性假瘤的B超及彩色多普勒血流图像的诊断

分析经手术及病理证实的7例肝脏灸性假瘤的临床、B超及彩色多普勒血流图像特征。结果显示多数病例具有低回声、边界较清楚、内部回声不均匀、肿块多数小于5cm等特征。3例作彩色多普勒血流图像显示,其中2例病灶内部为静脉型血流图像,1例有少量动脉型血流频谱,但ARI<46％。临床及CT无特殊表现。     

胸腰椎骨折脱位的外科治疗

ISCHEMIC PAPILLOPATHY AND CONTRACEPTIVES

In January and again in April 1985, a 30-year old woman received 150 mg injections of Depo-Provera for contraception. 3 days after the 2nd injection, she experienced blurred vision in both eyes and was diagnosed as having bilateral papilledema. Her vision improved after treatment with vitamin B1 and other drugs. But optic atrophy of the right eye and papilledema of the left eye remained. In July 1985, after an injection with Depo-Provera, her vision again worsened. The woman received no more Depo-Provera after this time. In early 1987, she was referred to Beijing's Tong Ren Hospital, where she was diagnosed as having bilateral ischemic papillopathy and optic atrophy. There have been few documented cases in medical literature of ocular complications related to use of contraceptives. In 1981, Petursson et al. reported a case of macula edema resulting from oral contraceptives. In animal studies, oral contraceptives have been linked to papilledema and retinal vein obstruction. The case reported here is the 1st to link use of Depo- Provera with ocular complications.     

蛋白尿可预测急性缺血性卒中的出血性转化

脑缺血后的出血性转化(hemorrhagic transformation,HT)似乎与继发于缺血过程的内皮细胞破坏有关。最近已证实,蛋白尿是慢性内皮功能损伤的一种标记物。为了探讨急性缺血性卒中患者中蛋白尿与HT的关系,西班牙学者Rodriguez-Yanez等进行了一项研究。纳入200例发病24 h内的缺血性卒中患者,51.5%为男性,平均年龄(72.5±8.5)岁。在4-7 d之间进行     

儿科护理纠纷原因分析及防范措施

随着社会的进步，人们维权意识逐渐加强，护理纠纷的发生呈上升趋势，儿科病房因其服务对象的特殊性，护理纠纷更易发生。现将原因分析及防范措施报告如下。     

烧伤后肠源性高代谢及其调理

烧伤后高代谢是创伤应激、缺血缺氧、炎症反应的重要组成部分。适度代谢反应有利于伤后机体修复，代谢率过高则加剧耗损，不利于机体恢复。烧伤后高代谢来源主要是创面，已是公认的事实，但伤后是否存在内源性特别是肠源性高代谢，国内外均未见报道。如确实存在肠源性高代谢，则给予适当调理措施，降低伤后高代谢，必将有利于烧伤机体恢复。     

肝动脉化疗栓塞治疗原发性肝癌常见副反应及并发症的护理对策

经导管肝动脉化疗栓塞术 (THACE)已成为公认的中晚期肝癌的首选疗法。我院自 1992年以来采用碘油化疗乳剂栓塞方法治疗中晚期肝癌 3 2 0 0人次 ,取得了较好的治疗效果。同时THACE也出现了一些副反应及并发症 ,为使肝癌的THACE治疗能以最小的代价取得最好的疗效 ,积极有效的护理是非常重要的 ,通过多年的临床实践得以验证 ,现总结如下以供大家借鉴。1　常见副反应及护理1.1　发热　可能是肿瘤组织坏死、脱落、吸收所致。给予物理降温或药物降温 ,消炎肛塞或巴米尔口服效果好。同时注意保暖 ,及时更换衣被 ,预防受凉。1.2　穿刺部位的…
