Abstract: OBJECTIVE: Stem cell transplantation has been used in the clinical treatment of diabetic lower limb vascular diseases. The conclusions were inconsistent due to the small sample size of each study. This article systematically reviewed the safety and efficacy of stem cells transplantation for diabetic patients with lower-extremity arterial disease. 
METHODS: PubMed, The Cochrane Library (Issue 11, 2019), EMbase, CNKI, CBM, VIP and Wanfang databases were electronically searched to collect randomized controlled trials of stem cell transplantation for diabetic patients with lower-extremity arterial disease from inception to December 10, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. 
RESULTS:  A total of 13 randomized controlled trials involving 546 patients, with 287 patients in stem cell transplantation group and 259 patients in conventional treatment group were included. The meta-analysis results showed that compared with the conventional treatment group, stem cell transplantation could significantly decrease the rate of lower limb amputation (RR=0.29, 95%CI: 0.10-0.84, P=0.02], improve the collateral angiogenesis (RR=3.16, 95%CI: 2.12-4.70, P < 0.000 01), increase ankle brachial pressure index (MD=0.17, 95%CI: 0.10-0.24, P < 0.000 01), transcutaneous oxygen pressure (MD=7.71, 95%CI: 3.99-11.43, P < 0.000 01), skin temperature (MD=1.90, 95%CI: 1.28-2.53, P < 0.000 01) and intermittent limp distance (MD=150.61, 95%CI: 43.49-257.74, P=0.006), reduce the scores of rest pain (MD=-1.16, 95%CI: -1.92 to -1.30, P < 0.000 01), and cold feeling (MD=-2.00, 95%CI: -2.49 to -1.50, P < 0.000 01). No severe complications such as death, neoplasm, or hepatorenal function impairment were observed in all of our included studies. 
CONCLUSION: Stem cell transplantation maybe an effective and safe therapeutic method for diabetic patients with lower-extremity arterial disease. However, due to the limited quantity and quality of included studies, more high-quality, long-term follow-up and large sample size randomized controlled trials are needed to confirm the above conclusions.
