Intervention / Traitement |
|---|---|
|
Expérimental: autologous bone marrow mononuclear cells
Bone marrow come from the patients himself/herself.
With a conventional method and reagent,Ficoll, mononuclear cells were isolated with deleting erythrocyte by density gradient centrifugation.
|
Bone marrow was taken from patient oneself and mononuclear cells were isolated with deleting erythrocyte by density gradient centrifugation.
Bone marrow mononuclear cells were transplanted into ischemia regions of lower limb through intramuscular injection.

Mesures de résultats secondaires
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
ulcer size
Délai: Post cell transplantation: 1, 3, 6 months
|
Measuring ulcer area (cm2) and depth (mm)of limb : For each ulcer , photographically record the area and depth with a ruler in order to calculate the ulcer area in square millimeters.
|
Post cell transplantation: 1, 3, 6 months
|
|
rest pain score
Délai: Post cell transplantation: 1,3, 6 months
|
Scoring the rest pain based on the degree of pain as following five scales): 0 level-0 point: no pain;
Before transplantation: points; after transplantation: points. |
Post cell transplantation: 1,3, 6 months
|
|
cold sensation score
Délai: Post cell transplantation: 1,3, 6 months
|
based on a sense of cold as following five scales: 0 level-0 point: no cold sensation;
|
Post cell transplantation: 1,3, 6 months
|
|
Resting ABI
Délai: Post cell transplantation: 1,3, 6 months
|
Measurement of ABI(ankle brachial index, ABI): Measure arterial pressure with a laser Doppler, and then calculate the ankle-brachial index, that is a ratio of ankle arterial blood pressure to brachial arterial blood pressure at rest.
|
Post cell transplantation: 1,3, 6 months
|
|
Resting TcPO2 (mmHg)
Délai: Post cell transplantation:1, 3, 6 months
|
Transcutaneous oxygen pressure(TcPO2) should be measured at the same site in the ischemic limb at rest.
|
Post cell transplantation:1, 3, 6 months
|
|
Collateral vessel score
Délai: Post cell transplantation: 1,3, 6 months
|
Collateral vessel score: Using computed tomographic angiography to score the collateral vessel formation. A mean score is obtained for each ischemic limb by 3 independent interventionists based on the following 4 level score: 0 (no new collateral vessels)
|
Post cell transplantation: 1,3, 6 months
|
|
Skin microcirculation measurement
Délai: 1,3,6 months post cell transplantation
|
using PeriMed "laser-Doppler flowmetry" measure the skin microcirculation on the same site in the ischemic limb at rest.
|
1,3,6 months post cell transplantation
