Human rotavirus has been discovered since the early 1970s, which is still a primary pathogen causing infant diarrhea under the age of five. Each year about 600,000 infant died of severe body dehydration caused by rotavirus infection. Since the current rotavirus diarrhea have no specific therapeutic drugs, using vaccine to prevent rotavirus infection is an effective method. Research on a vaccine often involved in a multidisciplinary theory and technology. This article reviewed the epidemic situation of rotavirus,animal model,the body's immune response after infection, developing and using vaccine and other related issues.

BACKGROUND:The HOX gene family is a highly conserved transcription factor family,which affects the formation of basic axis and secondary axis during embryonic development,at the same time,it plays a pivotal role in the development of the central nervous system,axial skeleton,stomach intestine,urogenital system and external genitalia.OBJECTIVE:To investigate the interactional protein of HOXD13 in human embryo foot development at 14 weeks pregnancy.METHODS:Fetal foot tissues were harvested and protein extraction was performed using protein extraction kit,6 μg HOXD13 antibody was added for immunOprecipitatjOn experiment,which aims to obtain HOXD13 interactional proteins,while the non-specific IgG served as a negative control Subsequent to Bradford staining,the sediment protein bands were cut for mass spectrometry.RESULTS AND CONCLUSION:We obtained an interactional protein of HOXD13 in the human embryo foot at 14 weeks pregnancy,at the relative molecular mass of approximately 60 000.The protein was identified as zinc finger protein 548 using mass spectrum.HOXD13 may play a very important role in transcriptional control by HOXD13-zinc finger protein 548 protein complex in the human embryo foot at 14 weeks pregnancy.

BACKGROUND: Preliminary study shows that the FHL1 gene expression is down-regulated in muscle tissue of patients with clubfoot, and the gel retardation experiments have verified HOXD13 and FHL1 gene promoter region transcription factor predicted binding sites in vitro, but the experimental results are not enough to truly reflect in vivo transcriptional regulatory protein and DNA binding conditions.OBJECTIVE: Western-blot technique is utilized to further validate FHL1 and HOXD13 gene expression in protein levels in muscle tissue of patients with congenital clubfoot, the in vivo HOXD13 and predicted binding sites in embryonic foot development was verified using chromatin immunoprecipitation technology.METHODS: Muscle tissues were samples from 15 children with congenital clubfoot, in the Department of Pediatric Surgery, at the Second Affiliated Clinical Hospital of China Medical University, 3 copies of normal children foot muscle tissues at the same age were provided by the Forensic Medicine College of China Medical University, 1 case of aborted embryo at pregnancy 13 weeks were offered by Department of Obstetrics and Gynecology, at the Second Affiliated Clinical Hospital of China Medical University. All specimens used are given informed consents by the patients and their families. Western-blot method was applied to detect the expressions of HOXD13 and FHL1 in foot muscle tissue of 15 patients of congenital clubfoot and 3 normal children at the same age; The FHL1 gene upper stream HOXD13 binding sites was predicted using software, the interaction of HOXD13and FHL1 during embryonic development was verified with chromatin immunoprecipitation experiment, brain tissue without HOXD13 protein expression served as controls.RESULTS AND CONCLUSION: Compared with normal children foot muscle tissues, both HOXD13 gene (5/15) and FHL1 (7/15)were down-regulated in 15 patients of congenital clubfoot. An enrichment of the predicted HOXD13 binding site was observed in the precipitated human embryo foot tissues chromatin. No enrichment of the predicted site containing sequence was observed in the control brain chromatin; additionally, there was no enrichment of the control sequence. This study further verifies that, the FHL1 and HOXD13 gene expression are down-regulated in the foot muscle tissue of congenital clubfoot children patients; during development of human embryos, HOXD13 protein can bind with FHL1 promoter region binding sites to play its role in transcriptional regulation. It is indicated that in the human foot embryonic development, the down-regulation of HOXD13expression may result in reduced expression levels of FHL1, thereby affecting the foot muscle growth and differentiation, leading to clubfoot deformity occurring.
