Spinal fixed-point rotating reduction in treating lumbar disc herniation by three-dimensional MRI / 中国骨伤

<p><b>OBJECTIVE</b>To observe three-dimensional space position change of nucleus pulposus and nerve root before and after treatment of lumbar disc herniation by spinal fixed-point rotating reduction, and explore the mechanisms.</p><p><b>METHODS</b>Totally 52 patients with L5S1 lumbar disc hernation treated by spinal fixed-point rotating reduction were collected from April 2009 to June 2011. There were 33 males and 19 females with an average age of 34.6 years old (ranged, 19 to 55). Three-dimensional MRI were performed to observe relationship between nucleus pulposus and related nerve root,configuration change of spine and pelvic on coronary MRI.</p><p><b>RESULTS</b>MRI showed relationship between nucleus pulposus and related nerve root mainly located on axillary, shoulder, front and surround. Vertebral displacement disappeared, lumbocrural pain alleviated after manipulative therapy. All patients were followed up from 2 to 28 months with an average of 12 months, and no recurred. All patients recovered work. Nucleus pulposus had no change,while lumbral spinal and pelvic curve changed before and after admission.</p><p><b>CONCLUSION</b>Lumbar disc herniation combined with single (multiple) vertebral displacement,can cause biomechanical properties of nucleus puplosus and related nerve root, while spinal fixed-point rotating reduction can correct vertebral displacement, recover balance between inside and outside of spinal.</p>

Study on the mechanism of Feng's spinal manipulation for treatment of lumbar disk hernation with a calcified herniated mass using 3D CT / 中国骨伤

<p><b>OBJECTIVE</b>To measure position changes of lumber disk herniation before and after treatment of Feng's spinal manipulation to study the mechanism of the manipulation for lumber disk herniation.</p><p><b>METHODS</b>In 2010, 8 patients with lumber disk herniation were treated by Feng's spinal manipulation, including 3 males and 5 females who ranged in age from 14 to 53 years with a mean of 35.4 years. The patients received CT scan before and after treatment. All images were reconstructed to measure the distance between the apex of the calcified lumber disk herniation and the top of the next adjacent spinal process.</p><p><b>RESULTS</b>The position of calcified lumber disk herniation underwent change after Feng's spinal manipulation, with a slight subluxation between the two adjacent vertebrae.</p><p><b>CONCLUSION</b>If subluxation is restored,the relation between the nerve root and the hernation will undergo change, followed by subsequent change of the hernation mass, thus restoring the inner-outer balance of the spinal column system.</p>

Treatment of the lumbar disc herniation of sequestered type with Feng's spinal manipulation / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the clinical effect of the treatment for sequestered type lumbar disk herniation (SLDH) with FENG's spinal manipulation.</p><p><b>METHODS</b>Forty-one patients (27 male, 14 female) were treated by FENG's spinal manipulation. The clinical results were measured by the Japanese and FENG's lumbar treatment standard and evaluated by scoring system for assessment of treatment for low back pain between pre- and post-treatment. To measure MRI sagittal index (SI) of lumbar disc herniation between pre- and post-treatment.</p><p><b>RESULTS</b>The score of subjective symptoms and clinical signs increased obviously after treatment. There was no statistical difference of SI between pre- and post-treatment (P<0.05). The outcome of treatment was satisfying.</p><p><b>CONCLUSION</b>The major pathologic change of SLDH is the single/multiple vertebral subluxation. FENG's spinal manipulation can correct the vertebral subluxation which leading to the series of clinical manifestations. The good clinical outcome may due to the alleviation of distortion and tension of dura and nerve root with the recovery of the spinal column's stability.</p>

Pilot study on clinical application of hepatic perfusion with multi-slice spiral CT / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To research the value of hepatic perfusion with multi-slice spiral CT in the diagnosis of liver diseases.</p><p><b>METHODS</b>Among the 48 patients undergone dynamic CT of the liver, 20 were volunteers without hepatic disorder, 17 with cirrhosis, 11 suffered from hepatic cancer. The perfusion indexes were calculated and compared.</p><p><b>RESULTS</b>(1) Compared with the control group, HPP (ml/min/ml), PPI and HPP/HAP of patients with cirrhosis were significant lower (HPP: 0.49+/-0.19 vs 0.60+/-0.16, P=0.038; PPI: 0.58+/-0.14 vs 0.67+/-0.06, P=0.015; HPP/HAP: 1.63+/-0.87 vs 2.12+/-0.65, P=0.04), whereas HPI was higher (0.42+/-0.14 vs 0.33+/-0.06, P= 0.015), which indicated the decrease of portal inflow and the increase of arterial inflow in cirrhosis patients. (2) Patients with hepatic cancer got a significant higher average HAP than that in volunteers and cirrhosis patients (F=11.71, P<0.001), while their HPP and HPP/HAP showed significant declining (F=22.84, P=0.0001; F=20.67, P<0.0001, respectively), which implied that hepatic cancer was mainly supplied by artery.</p><p><b>CONCLUSIONS</b>Hepatic perfusion with multi-slice spiral CT is an non-invasive technique to evaluate the arterial and portal inflow separately, which can inflect the hemodynamic change of the lesion by the perfusion indexes, and identify the condition of the tissue round the lesion prior to morphologic change. This method shows important value of diagnosis and differential diagnosis in hepatic diseases.</p>
