Effect of Kidney-tonifying Method on OPG/RANK/RANKL Signaling Pathway in Postmenopausal Osteoporosis Animal Model: A Meta-analysis
As the problem of global aging intensifies,postmenopausal osteoporosis (PMOP) has become a global health problem among females. At present,the commonly used biological agents have been proved not suitable for long-term use due to multiple adverse reactions. Several Meta-analyses have confirmed the good safety and effectiveness of kidney-tonifying method against PMOP,but its therapeutic mechanism remains unclear. The purpose of this Meta-analysis was to evaluate the effect of kidney-tonifying method on osteoclastogenesis inhibitory factor(OPG)/receptor activator of nuclear transcription factor (NF)-
κ
B (RANK)/receptor activator of NF-
κ
B ligand (RANKL) signaling pathway in PMOP animal model,so as to provide an experimental basis for the treatment of PMOP with kidney-tonifying method.

The related articles were retrieved from PubMed,Ovid Medline,Embase,China National Knowledge Infrastructure (CNKI),Chongqing Weipu Database for Chinese Technical Periodicals (VIP),and Wanfang Data Knowledge Service Platform with the retrieval time set from their inception to January 2020. The quality of each included article was evaluated using the SYRCLE's risk of bias tool. Then RevMan 5.3 was utilized for Meta-analysis according to the Cochrane systematic review methodology.
Result
2
Thirty-two studies involving 619 rats were included. The quality score of these studies ranged from 3 to 5 points. The results of the Meta-analysis indicated obvious advantages of kidney-tonifying method in increasing bone mineral density (BMD)[standardized mean difference (SMD)=2.01,95% confidence interval(CI)=1.50-2.52,
0.000 01) and RANK mRNA (SMD=-3.18,95% CI=-6.19--0.18,
P
<
0.05) expression and RANKL protein expression in bone tissue (SMD=-3.99,95% CI=-5.47--2.50,
P
<
0.000 01).
Conclusion
2
The kidney-tonifying method has been proved to possess potential advantages in regulating the balance of OPG/RANK/RANKL signaling pathway in PMOP animal model. Nevertheless,more large-sample sized,properly designed,and high-quality animal experiments are still needed for further verification.
