Benign infantile convulsions associated with mild gastroenteritis (BICE),known as convulsions with mild gastroenteritis,is a kind of non-febrile convulsions disease associated with acute infantile gastroenteritis.Patients with BICE often have mild gastroenteritis and tonic-clonic seizure manifestation,but no apparent disturbance of water,electrolyte and acid base was observed.BICE,the main etiological agent of which is Rotavirus,is a kind of self-limited disease with favorable prognosis,and no requiring of continuous anticonvulsant treatment.

Bronchial asthma is one of the most common diseases in children's respiratory system.Its frequent attacks seriously affect children's health,learning and life,bring great economic burden and mental pressure to families,leading to huge medical and health resources consuming.Many scholars have studied that ADAM33 is a susceptible gene for asthma.This article reviews the relationship between ADAM33 gene polymorphism and asthma,the pathogenesis of ADAM33 in asthma and the new progress in the treatment of ADAM33.

OBJECTIVE：To establish and optimize a extraction method of Fructus Gleditsiae Abnormallis ，and to analyze and identify chemical components of the extract simultaneously. METHODS ：Fructus Gleditsiae Abnormallis was extracted with CO 2 supercritical fluid extraction （SFE）method. Based on single factor tests ，using extraction yield as index ，extraction temperature ， extraction pressure and extraction time as investigation factors ，SFE technology was optimized with orthogonal test ，and validation test was performed. Chemical components in the extract were identified by GC-MS. Relative percentage of each component was calculated with area normalization method. RESULTS ：The optimal SFE extraction technology of Fructus Gleditsiae Abnormallis was extraction temperature of 60 ℃，extraction pressure of 300 MPa and pression time of 15 min. Average extraction of 3 times of validation tests was 1.73％（RSD＝1.78％，n＝3）. The 48 components in the extracts of Fructus Gleditsiae Abnormallis were identified，which accounted for 98.31％ of the total amount of the extracts. The extracts of Fructus Gleditisae Abnormalis mainly included organic acids ，accounting for 36.99％，followed by alkaloids ，accounting for 12.59％ in total. Main components were palmitic acid （16.62％），oleic acid （14.12％），N-aminotetrahydropyrrole（9.79％），2，6-dimethyloctane-1，7-dien-3-ol（5.95％）， tetrahydropyran（3.83％），vanillin（3.39％），etc. CONCLUSIONS ：SFE method of Fructus Gleditisae Abnormalis is established successfully，and the extract is mainly organic acids.
