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 investigate the experience of intrauterine device(IUD)removal in patients with cervical cancer after radiotherapy.Methods A total of 23 patients with cervical cancer after radiotherapy underwent abdominal ultrasound guided hysteroscopic removal of IUD in our department from January 2020 to December 2022.For vaginal and/or cervical adhesions,blunt separation of adhesions was performed by using hysteroscope head or curved forceps under abdominal ultrasound guidance.If it was difficult to separate the adhesions for hysteroscope head entering the uterine cavity,a probe was inserted into the uterine cavity under ultrasound guidance,and the cervical canal was gradually expanded to 6-caliber dilation rod.Then the hysteroscope was inserted again into the uterine cavity.For obvious cervical atrophy that was tough in which cervical forceps could not be used to clamp the cervix,a 1-0 absorbable suture line was used to suture the anterior and/or posterior lips of the atrophied cervix at the top of the vagina,with an assistant firmly pulling and fixing the cervix.Results There were 4 cases of vaginal partial adhesions and cervical contracture,10 cases of cervical contracture,and remaining 9 cases having no vaginal adhesions and cervical contracture.Under hysteroscopy,there were 3 cases of cervical adhesions,2 cases of endometrial polyps,1 case of submucosal uterine fibroids,2 cases of uterine abscess,2 cases of incarcerated IUD,and remaining 13 cases having normal uterine cavity morphology.All the 23 cases of IUD were successfully removed by using abdominal ultrasound guided hysteroscopy(circular shaped in 12 cases,uterine shaped in 6 cases,V-shaped in 2 cases,Y-shaped in 1 case,T-shaped in 1 case,and umbrella shaped in 1 case).The surgical time was(19.2±10.9)min,and there were no complications such as false passage formation,uterine perforation,organ damage,massive vaginal bleeding,transurethral resection of the prostate syndrome,infection,embolism,or shock.The 23 cases were followed up for 2-24 months postoperatively,with a median of 12 months.One case continued concurrent radiotherapy and chemotherapy,3 cases continued post-loading radiotherapy,1 case continued chemotherapy,and 2 cases received targeted treatment(distant metastasis).The remaining 16 cases recovered well in regular reviews without complications such as abdominal pain,fever,or vaginal bleeding.Conclusions If the size and location of the cancer lesion do not affect the removal of IUD after radiotherapy for cervical cancer,it should be removed as soon as possible.The application of abdominal ultrasound guided hysteroscopy in IUD removal in patients with cervical cancer after radiotherapy is safe and feasible to a certain extent.

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.
