急性期中风中医诊断与颅脑CT扫描关系分析

分析325例急性期中风的病类、证名诊断与颅脑CT扫描所见的关系,认为中络、中经以缺血性改变为主,病灶小,病灶周围多清晰或仅见模糊,占位表现不明显或较轻;中腑、中脏以出血性改变为主,病灶大,病灶周围多见水肿或模糊不清,占位表现明显,两者对比差异极显著(P<0.01)。病类诊断与中风的病变部位、病位侧、病灶数目;证名诊断与颅脑CT扫描所见皆关系不大(P>0.05)。

光固化复合树脂修补方法的比较研究

本研究评价了喷砂、氢氟酸(HF)、氢氟酸处理后涂KH-570乙醇液等方法时国产GD光固化复合树脂以及进口VIVADENT复合树脂的修补效果.结果表明:9.6%HF处理国产树脂、喷砂处理进口树脂均获得最大的修补强度,HF KH-570处理方法虽为每种材料中之最小者,但与其它修补方法间无显著性差异.     

经口补充谷氨酰胺对烧伤大鼠小肠功能的影响

大鼠２０％ＢＳＡⅢ°烧伤后１４天，门静脉、后腔静脉和腹主动脉血浆谷氨酰胺（Ｌ一Ｇｌｕｔａｍｉｎｅ，Ｇｌｎ）含量均明显降低，小肠粘膜的蛋白质、ＤＮＡ、ＡＴＰ含量及乳糖酶活性均明显低于正常。烧伤后在饲料中补充２％或５％Ｇｌｎ，大鼠血浆Ｇｌｎ水平，小肠粘膜的蛋白质、ＤＮＡ、ＡＴＰ含量，以及乳糖酶活性均明显高于烧伤对照和补充甘氨酸（Ｇｌｙ）组，其中ＡＴＰ含量和乳糖酶活性接近正常组。补充５％Ｇｌｎ的大鼠血浆Ｇｌｎ水平高于２％Ｇｌｎ组，其他指标则并不优于补充２％Ｇｌｎ的动物。上述结果表明，烧伤后经口补充Ｇｌｎ，有助于支持肠道的物质和能量代谢，防治或减轻肠道功能的损伤。     

VASCULAR COMPLICATIONS OF ELECTIVE LOWER LUMBAR DISC SURGERY

Lower lumbar disc surgery is an extremely common operation from which vascular complications are reported rarely. However vascular injury can occur with perforation of the anterior longitudinal ligament. External haemorrhage is uncommon and the true cause of the patient's hypotension may be misdiagnosed. If the hypotension is severe or prolonged laparotomy is indicated, to prevent exsanguination and to effect a repair of the vascular injury. Alternatively, if the injury is missed, an arteriovenous fistula may develop; this diagnosis may be delayed for months or years. One case of severe haemorrhage following lower lumbar disc surgery is reported and a further 69 cases of similar arterial injury have been reviewed from the world literature.     

HISTOLOGICAL COMPARISON OF THE THIRD INTERDIGITAL NERVE IN PATIENTS WITH MORTON'S METATARSALGIA AND CONTROL PATIENTS

This study compares the histology of the plantar-digital nerve supplying the third web space in asymptomatic patients with those who have clinically diagnosed Morton's metatarsalgia. Despite several studies concentrating on the histological changes in the interdigital nerve, the relevance of these changes is a matter of contention while the exact pathological process responsible for the symptoms has not been determined. The histological findings in control patients were identical to Morton's patients with the exception of demyelination, which was more common in the Morton's group. This suggests that the characteristic nodule and fibrotic changes seen in the interdigital nerves of patients with Morton's neuroma cannot account for the symptoms and that the changes seen in the neurovascular bundle are degenerative in origin and are found in asymptomatic patients.     

国产人α＿1型基因工程干扰素治疗慢性肝炎Ⅲ期临床试验

３９例慢性肝炎患者，其中乙型肝炎１２例，丙型肝炎２７例，接受人α＿１型基因工程干扰素治疗（ｒＨＩＦＮα＿１）。１０例丙型肝炎病人ｒＨＩＦＮα＿１每日肌注１×１０￣６Ｕ，连用９０天，１７例丙型肝炎病人和乙型肝炎ｒＨＩＦＮα＿１每日肌注３×１０￣６Ｕ，连用９０天。治疗后乙型肝炎组ＨＢｅＡｇ和ＨＢＶＤＮＡ的阴转率均为４１．６７％；丙型肝炎用１×１０￣６Ｕ／ｄ和３×１０￣６Ｕ／ｄ组ＨＣＶＲＮＡ阴转率分别为５０％和６４．７％，两个剂量组阴转率比较差异无显著性（Ｐ＞０．０５），治疗期间不良反应发生率较低，远期疗效尚待观察。     

Osteogenesis imperfecta: A clinical study of the first ten years of life

Summary One hundred twenty-seven children with osteogenesis imperfecta (O.I.) were studied during the first 10 years of life. According to Sillence, 40 patients were assigned to type I, 39 to type III, and 48 to type IV O.I. Centiles for height, weight, and the annual number of fractures could be established for the different types of O.I. The development of the skeletal changes could be documented for the different forms of the disease. At birth, the skeletal changes were significantly more severe in type III than in type IV patients. During the first 10 years of life the number of fractures, extent of skeletal deformities, and growth retardation did not differ between types III and IV. Only fracture nonunion, dentinogenesis imperfecta, and congenital cardiac malformations were more frequent in type III than in type IV. Papillary calcifications of the kidney and kidney stones were diagnosed in 4 type III and 2 type IV patients. Hemihypertrophy of the body developed, in 2 type I patients. Although types III and IV patients suffered from severe short stature, serum insulin-like growth factor (IGF) I was in the normal range.     

THE PSYCHOLOGICAL IMPACT OF HIP ARTHROPLASTY

The impact of total hip arthroplasty on psychological functioning was examined in 51 patients; 25 females and 26 males with a mean age of 65 years (range 42–81 years). Assessments of psychological well-being and distress were made with the Mental Health Inventory. Life satisfaction, self-rated health, and pain ratings were also obtained. Assessments were made prior to surgery, immediately after surgery, and at a 2 month follow-up. The operation produced significant improvements in psychological well-being (P < 0.001), psychological distress (P < 0.001). life satisfaction (P < 0.01), self-rated health (P < 0.001), and pain (P < 0.001). It is concluded that the changes in medical and functional status following hip arthroplasty documented in previous research are accompanied by substantial improvements in psychological state, and that the inclusion of psychological factors in hip arthroplasty research will provide a more comprehensive assessment of outcome.     

广西武鸣华侨农场心血管病危险因素的调查研究

对广西武鸣华侨农场4158人进行基线普查,410人进行膳食调查和作8小时夜尿电解质测定,并将高血压低发区广西的资料与高发区的北京作对比.结果显示,体重指数高是高血压一个重要的危险因素,而体重过重又与膳食中摄入碳水化合物和总热量大有关.另一主要的危险因素是钠,膳食中摄入钠高,尿Na和Na/K比值高者,血压水平和高血压的患病率亦高.
