Objective\ To investigate the manifestations of transcranial doppler (TCD)of spontaneous reperfusion in ischemic stroke.\ Methods\ Computed tomographic scan, TCD examination, and arterial digital angiography were performed in 56 patients with acute ischemic stroke of the middle cerebral artery (MCA) within 6 hours of the onset of symptoms. \ Results There were 38 patients who presented abnormal TCD findings with no flows or asymmetrial flow velocity in MCA of affected side. When we followed up these...

Objective\ To investigate the manifestations of transcranial doppler (TCD)of spontaneous reperfusion in ischemic stroke.\ Methods\ Computed tomographic scan, TCD examination, and arterial digital angiography were performed in 56 patients with acute ischemic stroke of the middle cerebral artery (MCA) within 6 hours of the onset of symptoms. \ Results There were 38 patients who presented abnormal TCD findings with no flows or asymmetrial flow velocity in MCA of affected side. When we followed up these patients 24hours,48hours,and 7days after the stroke, we found that the spontaneous reperfusion rate of obstructed MCA amounted to 50 percent and that the further the obstructed site , the bigger the rate was.\ Conclusion\ TCD is a simple, effective procedure for monitoring MCA.

AIM: To observe the application of autologous bone marrow mononuclear cells transplantation by intervention in treating necrosis of femoral head, and evaluate the curative effect. METHODS: Fifty-four patients (91 hips) with necrosis of femoral head and complete follow-up data were selected from the Cell Therapy Center, 463 Hospital of Chinese PLA between July 2004 and November 2005. Those diagnosed as the necrosis of femoral head, joint ache, and functional disturbance regardless of their gender or age were...

AIM: To observe the application of autologous bone marrow mononuclear cells transplantation by intervention in treating necrosis of femoral head, and evaluate the curative effect. METHODS: Fifty-four patients (91 hips) with necrosis of femoral head and complete follow-up data were selected from the Cell Therapy Center, 463 Hospital of Chinese PLA between July 2004 and November 2005. Those diagnosed as the necrosis of femoral head, joint ache, and functional disturbance regardless of their gender or age were selected, while those with severe heart failure or renal function abnormality that could not undergo the operation were excluded. Finally, 54 cases that were informed and signed the consent were involved in the experiment, including 45 males and 9 females aged 12-68 years. According to ARCO staging, the patients were divided into 42 hips at stage Ⅱ, 47 at stage Ⅲ and 2 at stage Ⅳ. The bone marrow of posterior superior iliac spine was taken to prepare the mononuclear cell suspension, which was punctured across the femoral artery by Seldinger method under DSA monitor, then 4F arterial sheath was implanted, followed by Cobra conduit across the arterial sheath. The conduit was bridged to the obturator artery and medial and lateral femoral circumflex artery to infuse the mononuclear cell suspension evenly. After operation, the patients were followed up to observe the symptom changes; one year later, X-ray or CT was performed to detect the pain and joint activity. The curative effect was evaluated by ①pain index: no pain symptom scored 3, as grade A in Harris hip score; pain sometimes scores 2, as grade B in Harris hip score; mild pain scored 1, as grade C in Harris hip score; moderate pain scored 0, as grade D in Harris hip score; ②function index: 4-5 marks in flexion, stretch, extension, contraction, and rotation degree of hip joint were regarded as 3 marks in Harris hip score; 3-4 as 2; 2-3 as 1; < 2 as 0; ③X-ray film index: no changes in femoral head appearance, clear stress trabecular bone, and the necrosis region shorted as 3 marks; slight shorted as 2; no changes before and after operation as 1; enlarged as 0; ④blood vessel index: after treatment, the medial and lateral femoral circumflex artery and their branches widened, increased, and prolonged above 1 cm scored 3; 1-0.5 cm scored 2; < 0.5 cm scored 1; and no changes scored 0. RESULTS: All 54 patients completed the one-year follow up of pain symptoms, joint function and imaging. ①The recheck at 12 month after operation showed that pain disappeared completely in 9 hips, pain was relieved in 61 ones, not relieved in 21 ones with the relief rate of 76.9%. ②Joint function was improved in 33 hips, not improved in 58 ones with the improvement rate of 36.3%. ③The X-ray film or CT, MRI one year later suggested that the bone density changed in the necrosis region of femoral head with different degrees, and the necrosis region was absorbed and lessened; the femoral head was silky and regular; there were 28 hips improved, 63 not improved even worsened with the relief rate of 30.1%. ④The intra-arterial digital angiography of feeding artery 12 month after operation appealed that among the 12 cases of 24 hips, 18 hips were improved with the improvement rate of 72.2%. CONCLUSION: Transplantation of autologous bone marrow mononuclear cell through intervention for treating necrosis of femoral head results in less injury and symptom improvement in clinic.
