Mechano growth factor (MGF) is an autocrine/paracrine factor and sensitive to mechanical stimulation. MGF can be highly expressed in various soft tissues under physical stimuli, biochemistry stimuli or in damaged situation. MGF may "compensate" the stress for tissue in the processing of tissue repair. MGF can effectively accelerate the repair of the soft tissue by promoting the proliferation, migration and differentiation of cells. This paper summarizes the MGF expressions in different soft tissues and their functions in soft tissue repair. The paper also discusses current problems and challenges in using MGF to repair the soft tissue.

Objective To analyze the contribution of dietary supplements to current vitamin mineral intakes in Beijing,China.Method By stratified cluster sampling method,3992 subjects aged 18y and above in 1440 households were investigated in 6 different regions in Beijing.Results The dietary intake of vitamin and mineral of men was higher than that of women,but the total intake of niacin and vitamin C was lower.Both dietary and total intake of vitamin and mineral in supplement users were higher that those in nonusers.In the group of supplement users,the contribution of supplement to thiamin,riboflavin and calcium intakes was 60% and 70%,47% and 45%,42% and 45% in men and women respectively.The percentage of supplement users who reached the current recommended intakes of vitamins and minerals was higher compared with that of nonusers,about 20 -30 percent higher for vitamin C and calcium.Conclusion The average intakes of vitamin and mineral are improved by using dietary supplements.Dietary supplements should be included in the future nutrition survey in China for improving the accuracy of nutrient’s intake.
