BACKGROUND:Wnt signal pathway is involved in the regulation of bone marrow mesenchymal stem cells differentiating into osteoblasts, promotes osteoblasts proliferation and differentiation, inhibits programmed death of osteoblasts, and indirectly affects the function of osteoclasts.
OBJECTIVE:To summarize the relationship between Wnt/β-catenin signal pathway and bone disease.
METHODS:A computer-based online search was performed to find papers published between January 2000 and January 2014 in CNKI database and Elsevier database. The key words were“Wnt/β-catenin, osteoblasts, bone marrow mesenchymal stem cells, osteoarthritis, chondrocytes”in Chinese. Documents concerning the effects of Wnt/β-catenin signal pathway on osteoblasts and bone disease were included.
RESULTS AND CONCLUSION:Wnt signaling pathway is consisted of Wnt/β-catenin signal pathway (Wnt typical signal pathway), Wnt/Ca2+signal pathway and Wnt/planar cellpolarity signal pathway. Wnt signaling pathway is one of the most important regulatory systems that plays a key role in modulating the differentiation, proliferation and programmed celldeath of osteoblasts, osteoclasts and chondrocytes. The role of Wnt signal pathway in patients with rheumatoid arthritis is mediated by osteoblasts. The inhibitory factor of Wnt signal pathway in osteoblasts is upregulated, which reduces the ratio of osteoprotegerin/receptor activating factor ligand, promotes the osteoclasts differentiation and immaturation. The researches addressing the components and effect of Wnt signal pathway are important for the special treatment of bone diseases and the prevention of osteoporosis or other bone diseases.

Objective To investigate factors influencing the quality of life (QOL) of cancer patients with bone metastases. Methods Eighty-two cancer patients with hone metastasis were investigated.A questionnaire designed according to European Organization for Treatment of Cancer quality of life questionnaire ( EORTC QLQ-C30),Monroe Dunaway Anderson symptom inventory-Chinese edition (MADSI-C) and hospital anxiety and depression scale (HADS) standards was used to collect the information. Results The average total standardized QOL score of these cancer patients was 53.28±19.20.Among the function subscales,social function got the lowest average score (47.54),while among the symptom subscales fatigue got the highest average score (56.65).According to the MDASI-C,the most serious symptom burdens were fatigue,distress and pain; working and walking experienced the most interference.The symptom burdens correlated significantly with the QOL results.Twenty-four of the patients (29.3%) had been diagnosed with anxiety,and 17 (20.7%) were diagnosed with depression.Anxiety and depression continued to be significantly associated with overall QOL and its various dimensions. Conclusions The results show that the burden of fatigue and pain,as well as of anxiety and depression are significantly associated with impaired QOL among cancer patients with bone metastasis.Work (housework) and walking were the most severely affected activities.Psychological rehabilitation should be focused on the comprehensive treatment of patients with bone metastasis along with other appropriate rehabilitation strategies to enhance their overall functioning,relieve their symptoms and improve their QOL.
