NCT04104412

Brief Summary

This experimental use umbilical cord mesenchymal stem cells in treatment of the early stage of lumbar discogenic pain (endogenous pain of the disc) to evaluate its safety and efficacy. This experimental is mainly aimed at over 18years old people, regardless of gender, with refractory and persistent back pain for more than 6 months. The efficacy and safety of mesenchymal stem cells (MSCS) were evaluated by low-temperature plasma ablation and intravertebral disc injection, which were divided into treatment group and control group.

Outcome Measures

Primary Outcomes (1)

  • Validity evaluation by detection the change of the VAS pain score relief rate for Lumbar disc pain of participants in different time point and compare with the VAS pain score before treatment

    Recording the VAS scores at 3, 6, 12 and 24 weeks after the operation and compare with the VAS score before the operation. Pain relief rate =(VAS before treatment - VAS after treatment)/VAS before treatment ×100%. VAS scale Use a line with 10 centimeters long as a point between 1 and 10 0 points, no pain, no pain sensation; 1-3 points, mild pain, no effect 4-6 points, moderate pain, affecting work but not life; 7-10 points, severe pain, severe pain, affect work and life. Efficacy evaluation: more than 75% is the basic remission; 50%-75% is effective; 25%-50% effective; Less than 25% is invalid. e.g. the VAS score before the operation is 8, the score in the third week after operation is 6, the pain relief rate is (8-6)/8x 100%=14.3% the VAS score before the operation is 8, the score in the sixth week after operation is 3, the pain relief rate is (8-3)/8x 100%=62.5%

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • age over 18
  • refractory and persistent lumbago pain for more than 6 months, with/without radiation pain in lower limbs, and poor conservative treatment effect;
  • the straight leg elevation test was 70 degrees negative;
  • MRI of lumbar spine showed herniated disc \< 6 mm, no obvious compression of spinal cord and nerve roots; T2-weighted mri of the lumbar spine showed decreased single/multi-segment signal (black disc sign) or High signal zone (HIZ) in the posterior part of the intervertebral disc annulus.
  • clinical signs of nerve localization were consistent with MRI changes;
  • subject gives informed consent and signs informed consent.

You may not qualify if:
