Fundamentals about onset and progressive disease character of type 2 diabetes mellitus

ResearchGate is a world wide web for scientists and researchers to share papers, ask and answer questions, and find collaborators. As one of the more than 15 million members, the author uploads research output and reads and responds to some of the questions raised, which are related to type 2 diabetes. In that way, he noticed a serious gap of knowledge of this disease among medical professionals over recent decades. The main aim of the current study is to remedy this situation through providing a comprehensive review on recent developments in biochemistry and molecular biology, which can be helpful for the scientific understanding of the molecular nature of type 2 diabetes. To fill up the shortcomings in the curricula of medical education, and to familiarize the medical community with a new concept of the onset of type 2 diabetes, items are discussed like: Insulin resistance, glucose effectiveness, insulin sensitivity, cell membranes, membrane flexibility, unsaturation index (UI; number of carbon-carbon double bonds per 100 acyl chains of membrane phospholipids), slow-down principle, effects of temperature acclimation on phospholipid membrane composition, free fatty acids, energy transport, onset of type 2 diabetes, metformin, and exercise. Based on the reviewed data, a new model is presented with proposed steps in the development of type 2 diabetes, a disease arising as a result of a hypothetical hereditary anomaly, which causes hyperthermia in and around the mitochondria. Hyperthermia is counterbalanced by the slow-down principle, which lowers the amount of carbon-carbon double bonds of membrane phospholipid acyl chains. The accompanying reduction in the UI lowers membrane flexibility, promotes a redistribution of the lateral pressure in cell membranes, and thereby reduces the glucose transporter protein pore diameter of the transmembrane glucose transport channel of all Class I GLUT proteins. These events will set up a reduction in transmembrane glucose transport. So, a new blood glucose regulation system, effective in type 2 diabetes and its prediabetic phase, is based on variations in the acyl composition of phospholipids and operates independent of changes in insulin and glucose concentration. UI assessment is currently arising as a promising analytical technology for a membrane flexibility analysis. An increase in mitochondrial heat production plays a pivotal role in the existence of this regulation system.     

关于医用B超基本工作原理及故障维修措施的研究

经济社会的快速发展,提升了人们的生活水平人们对医疗事业的发展提出了更高的要求,我国也加大了对医疗事业的建设与发展。尤其是所使用的相关设备与仪器。其中,医用B超就是最主要的医疗设备,能够通过设备的检查,对人体的身体情况以数据的形式展现,直接能够了解到人体的健康情况,提升医疗事业的技术水平,同时,也为医疗工作这提供了方便快捷的工作方式。但是,医用B超设备在使用的过程中,会受到一些因素的影响,使其发生故障,会对各项工作造成不同程度的影响。因此,需要对其加强管理,能够及时地发现故障问题,采取科学的措施解决,确保医疗事业的稳定发展。     

基于免疫系统非线性模型对中医正邪相争理论和扶正祛邪治则的一个非线性动力学诠释

文中基于免疫系统有关免疫活性细胞或分子与外来抗原相互作用的非线性的动力学模型对中医学正邪相争理论及其扶正祛邪治则进行了新的诠释,提出了新的研究思路。认为:中医学关于外感邪气致病的六经、卫气营血和三焦辨证在本质上是识别抗原与免疫活性细胞或分子相互作用的三种不同的非线性动力学诊断模式,其证相应于这一过程中不同的非线性动力状态,可以用一个或一组非线性动力学方程进行定量描述。一个证常常对应于抗原与免疫活性的细胞或分子非线性动力学相互作用相空间中的一个稳定或不稳定的极限环和混沌,这可以作为证诊断的图形或形象标识。以中医学扶正祛邪的治疗思想为先导,有可能研制出全新靶向的和更有效的治疗传染性疾病的药物。     

东林书院讲经活动与道德救世理念

明中后期，王学盛极一时，程朱式微，以顾宪成、高攀龙为首的东林学人以东林书院为依托，起而纠王学空疏之流弊。究明儒学道脉，“提撕天下万世”，成为其讲经活动的主要目的，儒家经典成为其讲经活动的主要内容，体现了学术与政治相结合的道德救世理念。     

医院文化的哲学伦理内核及其在现代医院管理中的重要作用

医院管理不是孤立自存的现象,由于管理者和被管理都生活在一定的医院文化氛围之中,因此,医院文化的哲学内核是现代医院管理知识的精髓,医院组织的价值观念、道德准则和思维方式,深刻地影响和制约着现代医院管理的原则和方法,决定着现代医院管理的实施和成败。     

More than wisdom

This paper presents and interprets empirical findings from field studies in a Bambara village in the Republic of Mali in order to place the traditional position of the elderly in cultural context. The significance of a seniority principle underlying the social structure of African society is emphasized. Thus attitude and behavioral changes which affect the status of the elderly have wider ramifications for the society as a whole. Attention centers on the role of age sets, myth and ritual, ancestor worship and socialization practices as elements of a total cultural system in which the rules of seniority provide an organizing force. In the last section, the ways in which social change threatens the viability of a social system governed by the seniority principle are reviewed. Signs of breaks in the solidarity of the traditional community are noted. Finally, two strategies for improving the position of the elderly in the African countryside as the traditional system disintegrates are proposed.To the people of Sonongo in gratitude.     

Pulmonary aspiration of gastric contents after a priming dose of vecuronium

A case is presented of a 16-year-old girl with ectodermal dysplasia for whom dental surgery under general anaesthesia was planned. Following a priming dose of vecuronium, and immediately after injection of sodium thiopentone (5 mg·kg⁻¹) pulmonary aspiration of gastric contents occurred. It is hypothesized that, because of the rapid speed of onset of neuromuscular blocking agents on the laryngeal muscles, that partial laryngeal paralysis was present at the time of induction of anaesthesia and that this was responsible in part for the episode of pulmonary aspiration.

Application of median-effect in quantitative analysis of antitumor drugs in vitro

Objective: To analyze quantitatively the synergistic and antagonistic effects of combined oxymatrine (OMT) and 5-fluorouracil (5-GU) on a cell line of human liver cancer (HepG2) with median-effect principle in vitro. Methods: The median-effect principle and MTT method were used in the quantitative analysis of effects of the two drugs. Results: Cytotoxic activity of the individual drugs enhanced as drug concentration increased. As fa=0.41, a CI equal to 1 indicated additivity; fa<0.41, a CI less than 1 indicated synergy; and fa>0.41, a CI greater than 1 indicated antagonism. The sequence of administration did not influence the cytotoxic activity of the combined antitumor drugs. The ratio of drug concentration was a factor that can influence the killing effect. Conclusion: The combined drugs interaction (CI<1) was synergistic at lower concentration and antagonistic at higher concentration. The ratio of drug concentration is a factor that can influence the killing effect.

论以服务对象为中心的医院管理道德原则

以服务对象为中心，就是医院管理者在医院工作管理过程中，从维护病人和服务对象的利益出发，将以为服务对象服务，满足服务对象合理医疗保健需求作为医院各项工作的中心，把服务对象至上、一切为了病人和服务对象的医院管理道德要求落实到各项管理措施之中。
