A Trapped Angel——The Significance of the role Hester in The Scarlet Letter

This paper puts forward the significance of the creation of Hester.Hester is a trapped angel,her gradually transformation process is a tragedy that she changes from a tradition resistor to a defender,and does not receive true love.This role enlightens us readers as to reflections on women’s status and on social transformation.At last,it gives a conclusion that Hester’s tragedy is sympathetic.It is not only the tragedy of Hester but also the tragedy of that era.

P物质对大鼠星状神经节细胞的影响

应用细胞内生物电记录方法，观察神经肽Ｐ物质（ＳＰ）对大鼠星状神经节能细胞的影响，用灌流或用加压向细胞周围施加ＳＰ可使部分细胞发生膜除极反应，用低钙或用含河豚毒素克氏液灌流神经节，并不影响ＳＰ引起的除极反应的幅度和时程。ＳＰ引起除极反应的同时常伴有膜电阻增大，当膜电位增大时，除极化反应幅度变小，反转电位为－８０ｍＶ至－１００ｍＶ，研究表明，ＳＰ对部分星状神经节细胞具有直接兴奋作用，并且ＳＰ对细胞膜的     

Mechanism for chronic pain generation

Neuropathic pain and the other abnormalities of sensation induced by axon injury or by peripheral nerve inflammation should result from functional compensations of the injured neurons during their regeneration. Ectopic distribution of proteins related to Na⁺, K⁺ and Ca²⁺ channels as well as of receptors on both membranes of injured axon and its cell body becomes a main pacemaker from which spontaneous ectopic afferent of primary sensatory neurons and crosstalk between neurons occur. Abnormal ectopic afferent activities lead to disorders of the sensation, such as hyperalgesia, allodynia, spontaneous pain and paraesthesia. Administration of some ion channel agents and/or α2-adrenergic blockers has shown efficiency in preventing neuropathic pain development and in relieving neuropathic pain.

Mental processes and disorders: A neurobehavioral perspective in human biometeorology

Summary Research concerning the complex relation between weather and psychological processes has emphasized three important issues: methodological problems, the determination of the major behavioral factors, and the isolation of neurobiological mechanisms. This paper reviews the current status of each issue. Weather changes are most frequently associated with behaviors that are the endpoints of inferred psychological processes that include mood, subclinical pain, anxiety, and the correlates of schedule shifts. Learning and conditioning appear to mediate a powerful influence over weather-related responses. This may explain the large individual variability in these behaviors. The most well-known group effects associated with weather changes involve psychiatric populations. Clinical subpopulations may respond in different ways to different aspects of the same weather system as well as to different types of air masses. Likely neurobiological mechanisms through which meteorogenic stimuli may mediate whole organismic effects include the locus coeruleal and limbic systems. Expected psychobiological consequences are examined in detail. The magnitude and temporal-spatial characteristics of weather effects indicate they are the subject matter of behavioral epidemiology.
