Overview
Brief Summary
This study aims to investigate the safety and efficiency of Human Umbilical Cord Mesenchymal Stem Cells (hUCMSC) for treating lumbar disc degeneration diseases. We hypothesize grafting hUCMSC into the degenerative disc leads to symptoms relief and slow down the progression of disc degeneration.
Detailed Description
Lumbar disc herniation causes patients severe lower back pain and radicular pain to decrease the quality of life and lead to great economic burden to patients and society. In recent years, full endoscopic discectomy has been widely used in the treatment of lumbar disc herniation due to its advantages of reduced trauma, enhanced recovery and less cost. However, the reherniation of the residual nucleus pulposus still exist after nerve root decompression. It is urgent to use stem cell and tissue engineering to replace the resection tissue and repair the residual nucleus pulposus for disc resealing. To observe the safety and efficacy of human umbilical cord mesenchymal stem cells (hUCMSCs) in the treatment of lumbar disc degeneration. This clinical trial is aimed to include a single group of 20 patients with lumbar disc herniation. Twenty million hUCMSCs will be injected into the lumbar disc of the enrolled patients in this non-random, self-controlled and single-dose open study design. The patients will be followed up for 3 months, 6 months and 12 months after the injection to evaluate the safety of the patients after grafting hUCMSCs. Additionally, improvement of patients' quality of life will be evaluated using the ODI score, VAS score and SF-36 score. Lumbar disc signals will be also quantified using MRI to demonstrate hUCMSCs transplantation could slow down lumbar disc degeneration.

Outcomes
Primary Outcomes
Lumbar disc signaling values from magnetic resonance imaging
Time Frame: Baseline, post-op 3months, post-op 6months, post-op 12months
Changes from baseline in Lumbar disc signaling values from magnetic resonance imaging
Secondary Outcomes
- Visual Analogue Scale (VAS) (0-10 scores, the higher scores mean a worse outcome)(Baseline, post-op 3months, post-op 6months, post-op 12months)
- Oswestry Disability Index(ODI) (0-50 scores, the higher scores mean a worse outcome)(Baseline, post-op 3months, post-op 6months, post-op 12months)
- The Short Form (36) Health survey (SF36) (0-100 scores, the higher scores mean a better outcome)(Baseline, post-op 3months, post-op 6months, post-op 12months)
- Disc Height Index (DHI) from X ray(Baseline, post-op 3months, post-op 6months, post-op 12months)
- Size of herniated nucleus pulposus from magnetic resonance imaging(Baseline, post-op 3months, post-op 6months, post-op 12months)
- Number of participants with treatment-related adverse events by CTCAE v4.0(From baseline until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months)
