急性心肌梗塞错误溶栓治疗12例分析

自1993年12月至1995年8月，对155例急性心肌梗塞（AMI）病人进行溶栓治疗，12例发生误溶(7．7％）。其中早期复极综合征4例，室壁瘤2例，心肌炎1例，心肌病1例，完全性左束支阻滞1例，间歇性左前分支阻滞互例，其它2例。本文分析了误溶病例与AMI的鉴别要点，并提出了减少误溶，提高诊疗水平的措施。     

环氧乙烷对大鼠DNA损伤机理的研究

为探讨环氧乙烷（ＥｔＯ）对ＤＮＡ分子水平的损伤作用，采用血红蛋白基因特异性的单引物，对用ＥｔＯ染毒不同时间的Ｗｉｓｔａｒ雄鼠和对照个体的肝、肾、睾丸等组织的ＤＮＡ进行半随机ＰＣＲ扩增。结果显示：在吸入染毒（８００ｍｇ／ｍ３）６～９周条件下，ＥｔＯ可引起肝、肾、睾丸等组织不同程度的ＤＮＡ损伤，其中睾丸组织ＤＮＡ损伤最为严重。     

大鼠肝抑素样提取物的生物效应初探

从大鼠肝分离出小分子蛋白质,注入肝大部切除的大鼠体内。术后24h制备肝细胞悬液及骨髓细胞悬液,用流式细胞计测定细胞DNA含量。结果:①实验组大鼠每克体重注入肝提取物10～300μg,一致呈现4n肝细胞DNA复制受阻于G_1期,各类肝细胞数与正常大鼠的相似;②对照组大鼠,4n肝细胞由正常的68.1％降至30.9％,8n肝细胞由6.3％骤增至25.3％,并出现16.8％的4n～8n间8期肝细胞;③两组大鼠的骨髓细胞DNA含量均无变化。表明肝提取物中含有肝抑素样物质,它特异性地使再生肝的4n肝细胞增殖周期阻滞于G_1期及S早期。     

Genetic determinants of statin intolerance

Background  

Statin-related skeletal muscle disorders range from benign myalgias – such as non-specific muscle aches or joint pains without elevated serum creatinine kinase (CK) concentration – to true myositis with >10-fold elevation of serum CK, to rhabdomyolysis and myoglobinuria. The genetic basis of statin-related muscle disorders is largely unknown. Because mutations in the COQ2 gene are associated with severe inherited myopathy, we hypothesized that common, mild genetic variation in COQ2 would be associated with inter-individual variation in statin intolerance. We studied 133 subjects who developed myopathy on statin monotherapy and 158 matched controls who tolerated statins without incident or complaint.     

bcl-2反义寡核苷酸对膀胱癌BIU87细胞株的影响

目的:探讨bcl-2反义寡核苷酸对培养的膀胱癌BIU87细胞株的影响.方法:采用bcl-2基因第1外显子的反义寡核苷酸,以硫代磷酸修饰(PS-ASON),序列为5′-TCTCCCAGCGTGCGCCAT-3′,与膀胱癌细胞株BIU87共同孵育作为实验组.加入正义的bcl-2寡核苷酸,序列为5′-TACCGCGTGCGACCCTCT-3′(PS-SON)作为对照组,用流式细胞仪检测细胞凋亡和坏死率,电镜观察细胞形态变化.结果:与对照组相比,实验组的细胞坏死率明显上调,电镜下细胞形态呈坏死改变.结论:bcl-2的反义寡核苷酸引起膀胱癌细胞大量坏死,可能成为膀胱癌的治疗方法之一.     

Ergebnisse der strukturierten Konsensuskonferenz „Bild gebende Verfahren in der Unfallchirurgie“ und Methodik zur Messung der Akzeptanz unter Tagungsteilnehmern

Existing knowledge and present experience relating to the indications for imaging techniques in trauma surgery were summarised, screened and considered in different ways by representatives of various professional scientific bodies, with the aim of finding what procedures should be implemented as the primary examination techniques after a careful clinical examination when particular posttraumatic situations affecting the knee, foot, ankle, or hand were found. In the course of an interdisciplinary consensus conference the evidence-based recommendations prepared by a panel were discussed and modified, giving rise to statements on the suitability of the given imaging techniques in 28 different clinical situations immediately after a clinical examination, based on scientific evidence and medical consensus. The degree of consensus was measured and carefully documented. These statements were transformed into decision algorithms and presented to doctors working in accident and emergency medicine during a conference on trauma surgery, with the aim of.measuring the acceptance of the statements among those attending the trauma surgery meeting. The remarks made by the participants during the discussion and the results of the acceptance measurements clearly show the need for further discussion among experts.
