OBJECTIVETo explore an innovative technique that is aided by multi-disciplinary hybrid approach in identification and treatment of tracheoesophageal fistula (TEF) in children intraoperatively.

METHODFrom April 2008 to October 2011, 4 patients with isolated TEF were presented with 2 H-type fistulas and 2 recurrent TEF. For all the four cases, with the cooperation of the gastroenterologists, respiratory physician and surgeon, methylene blue was first injected into the trachea for detecting the dye in the esophagus by the gastroscopy. Bronchoscopy was performed where the fistula tract was shown by the methylene blue and a guide wire was passed through the fistula. The patients underwent rigid gastroscopy and the guide wire was identified and brought out through the mouth by biopsy pliers. This created a wire loop through the fistula. X-ray was then used to identify the level of the fistula. According to the level of the fistula it was determined whether surgical incision and approach should be used. The fistula was then repaired successfully by surgery.

RESULTIn the 4 patients, with the aid of gastroscopy and bronchoscopy, identification of the fistula intraoperatively was then facilitated by traction on the loop. The fistula was identified and repaired. There were no fistula recurrences.

CONCLUSIONMulti-disciplinary hybrid therapy for tracheoesophageal fistula in children is beneficial for the precise localization of the fistula. This new technique is an effective and definitive method in identification and treatment of TEF in children.

Methods The typical disabilities in children with ASD were analyze based on ICF-CY and literature review. The approaches of physical activity and exercise rehabilitation were discussed. Results There were two kinds of behaviors including repetitive behavior and communication impairments. The main functioning of children with ASD included special mental function and motor function in body function and body structure;interpersonal interactions, hand and arm flexibly use, walking and moving in activity and participation. Individualized physical activity plan for children with ASD should promote the development of motor skills, improve relevant functions and promote all-round developments. Conclusion It is useful to analyze the functioning and disability, to develop individualized plans of physical activity and sport rehabilitation, to improve total functioning and to promote all-round developments.

Objective To explore the functioning and disability and individualized rehabilitation strategies for children with cerebral pal-sy using ICF-CY. Methods ICF-CY core set for children with cerebral palsy was used, and literatures of functioning and disability (motor function) and physical activity and exercise rehabilitation for children with cerebral palsy were reviewed systematically. Based on the theo-retical framework of ICF-CY and the theories of children's development, the rehabilitation strategies for children with cerebral palsy were discussed. Results The main functioning and disability for children with cerebral palsy were impairment of brain structure and nerve system-and motor function at body level;activity limitation and participation restriction in cognition, mobility and self-care, and restriction in partic-ipation in games, leisure and educational activities at individual level and related environmental factors. The rehabilitation strategies of chil-dren with cerebral palsy should be based on the physical structure and function, activities and participation, as well as environmental factors, to develop programs that met the characteristics of the individual. Conclusion The characteristics of functioning and disability for children with cerebral palsy were analyzed using ICF-CY. Individualized rehabilitation strategies should be developed to promote the overall develop-ments for children with cerebral palsy.

Objective To investigate the effects of Longdan Xiegan Decoction on the expression of Notch signaling-related genes in rats with experimental autoimmune uveitis (EAU).Methods Totally 24 Lewis rats were randomly divided into normal control group,EAU model group and Longdan Xiegan Decoction treatment group.A rat model of EAU was established in the EAU model group and Longdan Xiegan Decoction treatment group,followed by intragastrical administration of Longdan Xiegan Decoction in the latter group after successful modeling.On day 12 after different treatments,the spleen and lymph nodes were isolated from rats of all the three groups for the collection of CD4 + T ceils,and the levels of both Th17 and Treg cells were analyzed by flow cytometry to calculate the ratio of Th17 to Treg cells.Meanwhile the levels of Notch1,Notch2,Notch3,Notch4 mRNAs expression were monitored by qRT-PCR.Moreover,the expressions of Notch signaling-related proteins were further detected using ELISA technique.Results Flow cytometry showed increased Th17 cell level but decreased Treg cell level in the EAU model group when compared with the normal control group.However,after treatment with Longdan Xiegan Decoction,the Th17 level was decreased,whereas the Treg level was increased,and the ratio of Th17 to Treg gradually restored to equilibrium when compared to EAU model group.qRT-PCR results showed that the expression levels of Notch1,Notch2 and Notch4 mRNAs in Longdan Xiegan Decoction treatment group were significantly higher than those in the normal control group (all P ＜ 0.01),but lower than those in EAU model group on day 12 after treatment (all P ＜ 0.01),without Notch 3 expression in the spleen and lymph nodes.In addition,Notch 1,Notch 2 and Notch 4 protein levels of the spleen and lymph nodes in Longdan Xiegan Decoction treatment group showed the similar tendency as compared to those of Notch 1,Notch 2 and Notch 4 mRNAs (all P ＜ 0.01),and the expression of Notch 3 protein was still not observed.Conclusion Longdan Xiegan Decoction can effectively relieve the imbalance of Th17/Treg cells in EAU rats,and its mechanism may involve the differentiation of naive CD4+ T cells into Th17 and Treg cells,which is regulated by Notch signaling.
