BACKGROUND:Bone morphogenetic protein 9 is proved to promote the osteogenic differentiation of various kinds of stem cel s, but whether it can induce the osteogenic differentiation of dental fol icle cel s in vitro is yet unclear. OBJECTIVE:To investigate whether bone morphogenetic protein 9 can induce the osteogenic differentiation of rat dental fol icle cel s in vitro. METHODS:Purified rat dental fol icle cel s at passage 3 were transfected with bone morphogenetic protein 9 adenovirus. Then, alkaline phosphatase activity, calcium deposition and expression of osteogenesis-related factors at mRNA and protein levels were detected in the dental fol icle cel s. RESULTS AND CONCLUSION:After transfection with bone morphogenetic protein 9, the dental fol icle cel s showed continuously enhanced alkaline phosphatase activities and obviously enhanced calcium deposition. Real-time PCR results demonstrated that the mRNA expressions of alkaline phosphatase, osteocalcin, bone sialoprotein, osteopontin and core binding factor were increased significantly. The western blot assay showed that the expression of osteopontin enhanced in the dental fol icle cel s after transfection with bone morphogenetic protein 9. In summary, bone morphogenetic protein 9 can induce the osteogenic differentiation of dental fol icle cel s.

In addition to the intervention given to the control group, the treatment group received auricular point sticking plus moxibustion at Zusanli (ST 36). The occurrence rate of post-operation nausea, vomiting and abdominal bloating was observed.Result The occurrence rate of nausea, vomiting and abdominal bloating was 11.7% in the treatment group, versus 33.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Auricular point sticking plus moxibustion at Zusanli (ST 36) is effective in preventing spleen-stomach disharmony due to intravenous analgesia pump, and can reduce pain and complications.

BACKGROUND:Recent studies have shown that osteoclast differentiation factor is closely related to osteoclast differentiation, formation and function in bone remodeling during orthodontic tooth movement. OBJECTIVE:To observe the effects of three kinds of orthodontic appliances on the expression of osteoclast differentiation factor at the pressure side of rat periodontal tissue during remodeling process and to explore the biocompatibility of the orthodontic appliances with the host tissues during orthodontic treatment. METHODS:Eighty healthy Wistar rats were selected to establish animal models of orthodontic tooth movement, and then randomly divided into four groups: control group, MBT group, Begg group, Damon Ⅲ appliance group. Four animal from each group were sacrificed at 3, 7, 14 days after wearing orthodontic appliances. The tartrate-resistant acid phosphatase staining was used to count the osteoclasts at the pressure side of alveolar bone tissue; real-time quantitative PCR detection to detect mRNA expression of osteoclast differentiation factor at the pressure side of periodontal tissue and time distribution characteristics. RESULTS AND CONCLUSION:Compared with the control group, the number of positive osteoclasts and mRNA expression of osteoclast differentiation factor at the pressure side of the alveolar bone tissue were increased with orthodontic time, reached the peaked at 7 days and then gradualy decreased. The number of positive osteoclastsand mRNA expression of osteoclast differentiation factor at the pressure side of the alveolar bone tissue were significantly higher in the Damon Ⅲ group than the other three groups at 7 days after orthodontic treatment (P < 0.05). These findings indicate that, during the bone remodeling, the number of positive osteoclasts changed in accordance with the mRNA expression of osteoclast differentiation factor, and at 7 days, the number of positive osteoclasts and mRNA expression of osteoclast differentiation factor were highest in the Damon Ⅲ group.

Objective To investigate curative effect of traditional open surgery and laparoscopic surgery on pediatric patients with cryptorchidism.Methods Sixty cases with cryptorchidism were randomly divided into two groups.Thirty cases in the control group were with open surgery,and 30 cases were given laparoscopic surgery and served as laparoscopic group.Operation time,blood loss,bed time,postoperative hospital stay,evaluating curative effect and complications were recorded.Results Twenty-three cases were unilateral cryptorchidism and 7 cases were bilateral cryptorchidism in laparoscopic group.The blood loss and operating time of patients with unilateral and bilateral cryptorchidism in laparoscopic group were (3.2± 0.5),(5.1 ± 1.4) ml,and (41.1 ± 6.3),(67.3 ± 5.6) min.In the control group,24 cases were with unilateral cryptorchidism,6 patients with bilateral cryptorchidism.The blood loss and operating time of patients with unilateral and bilateral cryptorchidism in control group were (13.4± 1.8) and (17.7 ± 2.1) ml,(56.1 ± 5.7) and (81.2 ± 8.9) min.The differences between groups were statistically significant (t =29.91,27.34,9.67,7.24;P＜ 0.05).The stay bed time and postoperative hospital time in observation group were (2.7±0.6),(4.3±0.9)d,significantly lower than those of the control group ((5.8 ± 0.7),(8.1 ± 0.5) d),and the differences were statistically significant(t =18.42,20.22;P＜0.05).Wound healing in two groups were better during follow-up periods,after operation,B ultrasound showed that 4 cases of poor blood supply,and located in the scrotum testis above middle,inelasti in control group,while there were without abnormal in observation grtoup with scrotal testis at bottom and elastic.The curative effect of observation group was better than that of control group (x2 =2.41,P＜0.05).Three cases of observation group occurred surgical infection.One case was scrotal testes retraction and 2 cases with atrophy,which needed a second operation.The complications occurred number of observation group was significant different from that in control groups(P＜0.05).Conclusion The laparoscopic is with small incision,good curative effect,quick recovery and less complications,and children with less pain,shorter hospitalization time,low cost than traditional open surgery treatment of children with cryptorchidism,which is worth popularizing widely used.
