1.Role of osteogenic factors in bone disease and formation
Chinese Journal of Tissue Engineering Research 2010;14(7):1286-1290
BACKGROUND: Many factors are expressed during bone formation and osteonosus, which can induce cartilage to transformed into bone, or induce periosteal cells to transform into chondrocytes.OBJECTIVE: To summarize the osteogenic factors in recent years, and explore the important roles of these factors in bone formation and osteonosus.METHODS: A computer-based online search of Medline database (2008-01/2009-07) and CNKI (2008-01/2009-07) was performed using the key words of "osteogenic factors, bone disease, bone formation, Intercellular Signaling Peptides and Proteins,osteogenesis" in English and "osteogenic factors, bone formation, bone disease, cytokine, stimulating factor" in Chinese. All the articles were limited to the English and Chinese languages. The content about the bone factors, bone formation or osteonosus was included. Repeated or old studies were excluded.RESULTS AND CONCLUSION: According to the exclusion criteria, 158 literatures were collected and the roles of osteogenic factors in bone formation and osteonosus were analyzed. Bone formation and osteonosus are complex processes, influenced by many hormones and systemic or local growth factors. A variety of bone growth factors participate in process of bone healing and bone metabolism-related disease, which act on the target calls through local autocrine/paracrine mode and influence the distant target cells through blood circulation mode. A great number of factors are involved in the process of bone cell proliferation,differentiation, matrix synthesis and osteonosus metabolism, such as the fibroblast growth factor, bone morphogenetic protein,platelet-derived growth factor, transforming growth factor, interleukin-1, insulin-like growth factor, growth hormone etc.Osteogenic factors play an important role in the process of bone formation and bone-related diseases. More and more factors have been used in clinical therapy and bone tissue engineering research, and their effects have been clinically proven.

BACKGROUND:The reports on bone morphogenetic protein-7 as a stimulating factor to induce osteogenic are relatively rare.
OBJECTIVE:To study the expression of alkaline phosphatase of periosteal cel s after induced by bone morphogenetic protein-7 in vitro.
METHODS:Periosteal cel s were obtained from adult tibial periosteum, and then the periosteal cel s were
cultured by routine method in vitro. The cel s were divided into experimental group and control group, and then cultured with bone morphogenetic protein-7 plus osteoblast culture adjuvants and simple osteoblast culture
adjuvants, respectively. The phase contrast microscope was used to observe the morphology and ultrastructure of periosteal cel s. Each group was observed at 7, 14 and 21 days, and three samples were observed at each time point. Alkaline phosphatase kit was used to detect the expression of osteoblast-specific markers alkaline phosphatase.
RESULTS AND CONCLUSION:After cultured for 7 days, the proliferation of periosteal cel s in the experimental group and the control group was increased obviously, and the expression of alkaline phosphatase was detected but less. The cel s were spindle in shape, while the expression of alkaline phosphatase in the experimental group was higher than that in the control group. After cultured for 14 days, the proliferation of periosteal cel s in the
experimental group and the control group was increased obviously, the cel morphology was changed from spindle-shaped to wide spindle-shaped, and the expression of alkaline phosphatase in the experimental group was
increased significantly when compared with the control group. After cultured for 21 days, the proliferation of periosteal cel s was detected in the experimental group and the control group, and the proliferation in the experimental group was more significant than that in the control group, the cel morphology was wide spindle-shaped, and the number of alkaline phosphatase in the experimental group was higher than that in the control group. Statistical analysis showed that the
positive rate of osteogenic markers alkaline phosphatase of bone morphogenetic protein-7 induced periosteal cel s in the experimental group was higher than that in the control group (P<0.01). It suggested that periosteal cel s had the
osteogenic and regeneration ability, the bone morphogenetic protein-7 could induce periosteal cel s, promote the expression of alkaline phosphatase, and could induce the periosteal cel s to transform into osteoblasts.

Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.
