ABSTRACT
OBJECTIVE@#To observe the difference in clinical efficacy between chicken-claw needling at Shangbaxie (Extra) and Hegu (LI 4) combined with acupuncture at Houxi (SI 3) and the conventional acupuncture at the 3 points for the treatment of hand dysfunction after stroke.@*METHODS@#Forty-two patients were divided into an observation group and a control group according to the random number table, 21 cases in each one. The chicken-claw needling was used at Shangbaxie (Extra) and Hegu (LI 4) on the affected side combined with acupuncture at Houxi (SI 3) in the observation group. The conventional acupuncture was performed at the same point as the observation group in the control group, once a day, 6 days for a course, 1 day of interval after a course, and the therapeutic effect was observed after 5 courses. The simplifying Fugl-Meyer Motor Function Rating Scale (FMA), the modified Barthel index and the Brunnstrom grading criteria were used to evaluate the hand function of the two groups before and after treatment.@*RESULTS@#The FMA score, Barthel index and Brunnstrom grade were improved after treatment in the two groups (all <0.05), and the FMA score, Barthel index and Brunnstrom grade in the observation group were better than those in the control group (all <0.05).@*CONCLUSION@#Chicken-claw needling at Shangbaxie (Extra) and Hegu (LI 4) combined with acupuncture at Houxi (SI 3) can effectively treat hand dysfunction after stroke, and the curative effect is better than the conventional acupuncture at the 3 points.

<p><b>OBJECTIVE</b>To evaluate the correlation of venous return disturbance (VRD), bone marrow edema (BME) and the amount of joint fluid with clinical symptoms in osteonecrosis of the femoral head (ONFH).</p><p><b>METHODS</b>Twenty patients (25 hips) with ONFH proved by pathology were parallelly examined by 1.5 T MR and medullograph.</p><p><b>RESULT</b>In total 25 hips VRD was observed in 16 hips with medullograph and 13 hips with the clinical symptoms (P <0.05). BME was found in 17 with MRI (P <0.01), and the was found in 15 hips with MRI (Spearman=0.949). VRD were found in 16 hydrarthrus.</p><p><b>CONCLUSION</b>ONFH patients with clinical symptoms have VRD, BME and the hydrarthrus. The medullograph is of value in monitoring the development of ONFH.</p>

<p><b>OBJECTIVE</b>To study the relationships among magnetic resonance imaging (MRI), histological findings, and insulin-like growth factor-I (IGF-I) in steroid-induced osteonecrosis of the femoral head in rabbits.</p><p><b>METHODS</b>Thirty rabbits were randomly divided into experimental Group A (n=15) and control Group B (n=15). The 7.5 mg/kg (2 ml) of dexamethasone (DEX) and physiological saline (2 ml) were injected into the right gluteus medius muscle twice at one-week intervals in animals of Groups A and B, respectively. At 4, 8 and 16 weeks after obtaining an MRI, the rabbits were sacrificed and the femoral head from one side was removed for histological study of lacunae empty of osteocytes, subchondral vessels, and size of fat cells under microscopy, and the femoral head from the other side was removed for enzyme-linked immunoadsorbent assay (ELISA) for IGF-I.</p><p><b>RESULTS</b>At 4, 8 and 16 weeks after treatment, no necrotic lesions were detected in Group B, while they were detected in Group A. Light microscopy revealed that the fat cells of the marrow cavity were enlarged, subchondral vessels were evidently decreased, and empty bone lacunae were clearly increased. The IGF-I levels in Group A were significantly higher than those in Group B. At 8 weeks after the DEX injection, the MRI of all 20 femora showed an inhomogeneous, low signal intensity area in the femoral head, and at 16 weeks, the findings of all 10 femora showed a specific "line-like sign". The MRI findings of all femora in Group B were normal.</p><p><b>CONCLUSION</b>MRI is a highly sensitive means of diagnosing early experimental osteonecrosis of the femoral head. However, the abnormal marrow tissues appeared later than 4 weeks when the expression of IGF-I increased. This reparative factor has an early and important role in response to steroid-induced osteonecrosis of the femoral head, and provides a theoretical foundation for understanding the pathology and designing new therapies.</p>
