BACKGROUND: Heal-all oral biofilm is a material utilized in repairing oral mucosa and soft tissues defects and characterized by degradation, easily preparation, long preserved duration, convenient transportation and good ossification, which has been widely used in dental implant as guided bone regeneration materials.OBJECTIVE: To check the clinical effective of Heal-all oral biofllm on guided bone regeneration in dental implant.METHODS: A total of 72 patients with bone defects in the implantation area were selected as subjects, who were divided into control group and experimental group at random. Bone defects around implants were repaired by guided bone regeneration technique with BME-10X medical collagen membrane and Heal-all oral biofilm respectively. X-ray and clinical examination were taken at 1 and 3 months after implantation. The amount of new.formed bone tissue was evaluated when stage Ⅱ operation was performed.RESULTS AND CONCLUSION: In stage Ⅱ operation, osseointegration was formed between implants and bone tissue in all 72 patients. The average rate of bone formation was 92% in the experimental group while 91% in the control group. All implants were successfully repaired with implant denture. Occlusal function was restored successfully with all 72 implants during the follow-up period of 3-24 months after restoration. As an alternative option of BME-10X medical collagen membrane, Heal-all oral biofilm can be used in guided bone formation clinically.

Transcriptional regulation is one of the major regulations in plant adventious shoot regeneration, but the exact mechanism remains unclear. In our study, the RNA-seq technology based on the IlluminaHiSeq 2000 sequencing platform was used to identify differentially expressed transcription factor (TF) encoding genes during callus formation stage and adventious shoot regeneration stage between wild type and adventious shoot formation defective mutant be1-3 and during the transition from dedifferentiation to redifferentiation stage in wildtype WS. Results show that 155 TFs were differentially expressed between be1-3 mutant and wild type during callus formation, of which 97 genes were up-regulated, and 58 genes were down-regulated; and that 68 genes were differentially expressed during redifferentiation stage, with 40 genes up-regulated and 28 genes down-regulated; whereas at the transition stage from dedifferentiation to redifferention in WS wild type explants, a total of 231 differentially expressed TF genes were identified, including 160 up-regualted genes and 71 down-regulated genes. Among these TF genes, the adventious shoot related transcription factor 1 (ART1) gene encoding a MYB-related (v-myb avian myeloblastosis viral oncogene homolog) TF, was up-regulated 3 217 folds, and was the highest up-regulated gene during be1-3 callus formation. Over expression of the ART1 gene caused defects in callus formation and shoot regeneration and inhibited seedling growth, indicating that the ART1 gene is a negative regulator of callus formation and shoot regeneration. This work not only enriches our knowledge about the transcriptional regulation mechanism of adventious shoot regeneration, but also provides valuable information on candidate TF genes associated with adventious shoot regeneration for future research.
