DNA vaccination, when applied with an immunosuppressant as adjuvant, can induce antigen-specific tolerance and prevent autoimmune disease.

Objective Intussusception is a common paediatric abdominal emergency in infants. The first-line treatment of choice in uncomplicated paediatric intussusception is enema reduction. The study aim was to provide an overview of the current national practice of enema reduction of paediatric intussusception in China. Methods A questionnaire on enema reduction of paediatric intussusception was sent to respondents (members of the Pediatric Anorectal Group, the Neonatal Group, the Society of Pediatric Surgery and the China Medical Association). Results Data from 128 questionnaires were analysed. Of these, 78.1% (100/128) reported the use of fluoroscopy, 17.2% (22/128) use of ultrasound monitoring, 78.9% (101/128) use of air and 17.9% (23/128) use of normal saline. A total of 78.9% (101/128) reported a success rate of 90%, 25.8% (33/128) reported that a paediatric surgeon managed the reduction, 18.8% (24/128) that a radiologist managed the reduction and 44.5% (57/128) that a paediatric surgeon and radiologist jointly managed the reduction. Conclusions There is large variation in the techniques of enema reduction of intussusception in China. Fluoroscopy-guided air enema reduction is mainly used. Enema reduction of uncomplicated cases of paediatric intussusception in China lacks standardization of equipment and personnel involvement.

Background: Gossypium hirsutum is highly susceptible to Verticillium wilt, and once infected Verticillium wilt, its yield is greatly reduced. But G. barbadense is highly resistant to Verticillium wilt. It is possible that transferring some disease-resistant genes from G. barbadense to G. hirsutum may contribute to G. hirsutum resistance to Verticillium wilt. Result: Here, we described a new gene in G. barbadense encoding AXMN Toxin Induced Protein-11, GbAt11, which is specifically induced by Verticillium dahliae in G. barbadense and enhances Verticillium wilt resistance in G. hirsutum. Overexpression in G. hirsutum not only significantly improves resistance to Verticillium wilt, but also increases the boll number per plant. Transcriptome analysis and real-time polymerase chain reaction showed that GbAt11 overexpression can simultaneously activate FLS2, BAK1 and other genes, which are involved in ETI and PTI pathways in G. hirsutum. Conclusion: These data suggest that GbAt11 plays a very important role in resistance to Verticillium wilt in cotton. And it is significant for improving resistance to Verticillium wilt and breeding high-yield cotton cultivars.
