目的探讨血浆载脂蛋白比值(apoAl/apoB)、BMI与冠状动狭窄程度的关系。方法将拟接受冠脉造影术检查的1079例患者作为研究对象,冠脉造影结果按Gensini积分评价,根据冠脉造影术结果将所有研究对象分成冠心病组(940例,积分0分)和对照组(139例,积分为0分);再根据Gensini积分将冠心病组分成三个亚组:轻度病变组(342例,1分≤积分30分),中度病变组(345例,30分≤积分60分),重度病变组(253例,积分≥60分)。测量患者身高、体重,检测血脂水平,计算体重指数(BMI)、apoAl/apoB值。结果冠心病组患者年龄高于对照组(P0.05),高血压病、糖尿病、吸烟、冠心病家族史比例均高于对照组(P0.05);BMI、TC、TG、LDL、apoB、Lp(a)、HCY水平均高于对照组(P0.05),HDL、apoAl、apoAl/apoB均低于对照组(P0.05)。冠心病患者Gensini积分与年龄、高血压病史、糖尿病史、吸烟史、冠心病家族史、BMI、TC、TG、LDL、apoB、LP(a)、HCY呈正相关(P0.05),与HDL、apoAl、apoAl/apoB呈负相关(P0.05)。高血压病史、糖尿病史、冠心病家族史、高BMI、高LDL、高apoB、高Lp(a)是冠心病的独立危险因素,apoAl、apoAl/apoB是冠心病的保护因素。结论低apoAl/apoB值或高BMI是冠心病的危险因素,能在一定程度上反映冠状动脉狭窄的严重程度,预测冠心病的风险。  相似文献

Two ligament systems of the larynx are demonstrated by dissection. The suspensory ligament of the esophagus is attached to the posterior aspect of the cricoid cartilage and is also a part of the fascial sheath which is common to the hyoid, thyroid, and cricoid. The ligaments at the inner margins of the vocal, ventricular, and aryepiglottic folds are distinctive in site and, inferentially, in function. The aryepiglottic ligaments join at the incisura between the arytenoid cartilages and are continued as the corniculopharyngeal ligament which splays into the flexible tissues in the anterior wall of the hypopharynx, posterior to the suspensory ligament of the esophagus. These ligament systems are involved in two different actions in swallow. The gross superior and anterior motions of the larynx are transmitted to the esophagus by the suspensory ligament, so that the esophagus is elevated in relation to the bolus and is also opened. These esophageal displacements resemble, in effect, the swallow displacements of the pharyngoesophageal segment and of the constrictor wall of the hypopharynx. The marginal ligaments of the laryngeal folds help to implement the constriction and closure of the larynx during swallow. By anatomical inference, the corniculopharyngeal ligament effects vertical traction within the flexible tissues of the anterior wall of the hypopharynx.  相似文献

BackgroundThe hospital is considered as one of the founding elements of modern medicine. Such an institution, originally born to be a center for housing the sick and the poor, has provided with a place to improve the medical knowledge and to educate new generations of nurses and physicians. This paper wants to remind the meaning and the development of the hospital institution in the western world.MethodsThe first part of this work analyzed the evolution of hospital, using a classical historiographical approach. In the second part, the history of the “Ospedale Maggiore” in Milan was used as a paradigm to describe the evolution of hospital from the Renaissance to nowadays through a “microhistorical approach”.ResultsThe origins of the public hospital are evidenced in early Christian age, when the Christian message led people to assist the sick and the poor and to establish centers for such interventions, initially in the house of the bishop, then in monasteries and, finally, in autonomous buildings (the hospitals). These institutions were economically supported by the donations of wealthy philanthropists. Since the nineteenth century the hospitals have changed their organization and functions, but have continued to associate the charity and the care.ConclusionChristian charity and the lay culture originated from it may be rightly credited not only as the founding element of ancient hospitals, but also as the virtue which has made possible for the development of medicine, as we know it.  相似文献

In studies with the isolated perfused working hearts from rats with experimentally induced diabetes, the ability of the hearts to survive during, and recovery from, 30 min of anoxia has been studied. In contrast with hearts obtained from normal rats, which gave good and sustained recoveries, the hearts from diabetic animals after an initial period of recovery (approx. 2 min), exhibited cardiac failure for periods of up to 4 min. After this period the hearts entered a second phase of recovery but did not recover to the same extent as the hearts from normal animals. Hearts of diabetic animals therefore appear to be more vulnerable to anoxic damage than do those from normal rats.Using metabolic inhibitors the biochemical basis of this transient post-anoxic failure in diabetic hearts was investigated. It was discovered that the immediate post-anoxic recovery of the hearts was supported in part by endogenous supplies of pre-formed high energy phosphates and in part from energy derived from the glycolysis of endogenous glycogen. During the initial recovery period of approx. 2 min there was little dependence upon the oxidative metabolism of either endogenous or exogenous substrates. In normal hearts the role of major energy provider was rapidly assumed by oxidative processes utilizing exogenous substrate. In the insulin deficient diabetic hearts the impaired transport of glucose into the cell and consequent energy shortage led to the transient cardiac failure and accounted for the delayed secondary recovery. This condition could be completely overcome either by the provision of exogenous insulin or by the provision of substrates such as pyruvate, acetate, citrate or hydroxybutyrate, whose efficient utilization was not impaired by an insulin deficiency.The relevance of these findings in the diabetic rat heart is discussed in relation to the known insulin deficiency occurring in the human during heart failure and the proposed importance of glucose metabolism in the support of the failing myocardium. In addition, these findings are considered in relation to the possible role of insulin both in the genesis and the treatment of heart failure with particular reference to heart failure in humans with diabetes mellitus.  相似文献
