Dynorphin/KOR inhibits neuronal autophagy by activating mTOR signaling pathway to prevent acute seizure epilepsy.

In previous studies, we found that dynorphin exerts antiepileptic effect by activating the kappa opioid receptor (KOR). However, the role of neuronal autophagy in dynorphin/KOR-mediated antiepileptic is still unclear. This study aimed to investigate the molecular mechanism of dynorphin's antiepileptic effect by inhibiting autophagy and reducing neuronal apoptosis.

[Allergens and their relationships to childhood bronchial asthma in the Jiading District of Shanghai].

Objective: To study allergens and their relationship to the occurrence of childhood bronchial asthma in the Jiading District of Shanghai.

Methods: Three hundred and eighty-two 4 to 12-year-old children with asthma in the remission stage from Nanxiang Hospital in the Jiading District of Shanghai were used as a case group (asthma group), and 402 children from two primary schools and two kindergartens in Jiading were enrolled by cluster sampling and served as control group. Parents of the children completed a questionnaire on living conditions and allergy-related disease history.
