Chinese Journal of Medical Education Research 2013;(4):412-414
Improving medical students' legal quality is not only the requirements of modern education and their self-improvement,but also the needs of reform on medical system in the new era and establishment of a harmonious relationship between doctors and patients.Medical universities should carefully integrate the existing law education resources and establish three staged teaching model (stages of basis law education,health law education and stage of comprehensive improvement) when being fronted with the education model which is unilateral,sporadic and lack of cohesion in order to improve the law quality of medical students.
4.Signiifcance of epileptiform discharges in anti-epileptiform drug therapy and prediction of relapse Reviewer
Journal of Clinical Pediatrics 2013;(8):788-790
EEGs performed for new-onset seizures show epileptiform discharge in approximately 18% to 56% of children and 12%to 50%of adults. EEG is the most commonly used means of neurological examination for epilepsy. Speciifc EEG abnormalities help characterize the seizure type and epilepsy syndrome, which allows more informed decisions regarding therapy and more accurate prediction of seizure control and ultimate remission. In certain cases, the EEG may detect more subtle seizures, including absence, myoclonic or partial seizures. In the therapy of epilepsy, the effect of different antiepileptic drugs on the inhibition of epileptiform discharges is different. Epileptiform discharges play a very important role in the prediction of recurrence and the decision to remove antiepileptic drugs.

P2X7 is the most important subtype of the ATP receptors known so far. Recent investigations showed that the downstream signaling pathway of P2X7 is coupled with several key inflammatory molecules including IL-1beta and IL-18, this suggests P2X7 might have roles in the inflammatory diseases. Moreover, attenuation of P2X7 by selective antagonists in vitro and knockout mice in vivo reducing the inflammatory response indicated that P2X7 is a potential therapeutic target for inflammatory diseases. However, most previous studies on P2X7 were focused on nerve system diseases most, while its effects in inflammatory respiratory diseases, especially in asthma, chronic obstructive pulmonary disease (COPD) and lung cancer have been poorly investigated. In this paper, we reviewed the research progress on the structure, distribution, biological activities of P2X7 and its relationship with inflammatory respiratory diseases including asthma, COPD and lung cancer, along with the development of P2X7 antagonist as therapeutics.
