BACKGROUND:Increasing evidence has shown that insulin-like growth factor-1 (IGF-1) plays a regulatory role in bone metabolism and increases bone formation,stimulates osteoblast number and activity,as well as reduces osteoclast differentiation and bone resorption.The mechanism of IGF-1 is an issue of concern.OBJECTIVE:To review the research advance in IGF-1 and the bone metabolism-related indexes in postmenopausal osteoporosis.METHODS:The first author searched the PubMed and CNKI databases between January 2012 and July 2016 using the keywords of "postmenopausal osteoporosis,insulin-like growth factor,bone metabolism,biochemical markers" in English and Chinese,respectively.The repetitive articles were excluded,and 36 eligible articles were enrolled for overview.RESULTS AND CONCLUSION:Bone resorption is increased in postmenopausal woman through the regulation of a variety of cytokines,in which IGF-1 in the blood is combined with IGF binding protein 3,making growth hormone play its biological role.In addition,the growth hormone in the blood directly acts on the adipose tissue,and muscle and bones.Growth hormone exerts a direct effect on bone tissue,promotes osteoblast maturation and differentiation,and enhances the expression of collagen and non-collagen through IGF-1-mediated indirect effect,thus promoting bone formation.The process of bone metabolism is able to reflect the activities of osteoblasts and osteoclasts and the changes of bone matrix and bone mineralization.In vitro experiments show that IGF-1 stimulates the proliferation of osteoblast precursors and differentiate into osteoblasts in a dose-dependent manner,promotes the expression of osteogenic markers such as alkaline phosphatase,type Ⅰ collagen,and osteocalcin,and also stimulates the activity and number of osteoclasts.However,there are few clinical reports and few observation indicators,resulting in a lack of reference range for the detection and treatment of osteoporosis,which needs further exploration.

OBJECTIVETo observe the clinical effects and explore the mechanism of the integrated traditional Chinese and Western medicine in treating atopic dermatitis (AD).
METHODSForty-seven patients with AD were randomly assigned to two groups, the control group and the treated group, they were treated with conventional Western medicine (10 mg Loratadine tablet, once daily) and with integrated medicine additionally given modified Jiawei Danggui Decection besides Western medicine respectively for 4 weeks. Double-sandwich ELISA was used to detect the levels of interleukin- 4, -10 and -12 (IL-4, IL-10 and IL-12) before and after treatment.
RESULTSThe total effective rate in the treated group was 56% (14/25 cases), better than that in the control group (22.7%, 5/22 cases), showing significant difference between the two groups (X2 = 5.38, P < 0.05). Before treatment the serum levels of IL-4, IL-10 were significantly higher and level of IL-12 was lower in AD patients as compared with those in healthy persons (P < 0.01); they all restored to normal in the treated group after treatment but unchanged in the control group, showing significant difference between the two groups (P < 0.01).
CONCLUSIONThe clinical effect of integrated traditional Chinese and Western medicine is ascertainable, its mechanism might be associated with the regulation on related cytokines.
