Curative effect of wilsonii injecta on severe head injury / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To study the curative effect of wilsonii injecta on severe head injury (SHI).</p><p><b>METHODS</b>A total of 120 patients with SHI were divided randomly into 2 groups, the patients treated with conventional methods as Group A (n=60) and the patients treated with wilsonii injecta as Group B (n=60). The changes of neural function indexes were evaluated with Glasgow Coma Scale (GCS) before treatment and with Glasgow Outcome Scale (GOS) after treatment, simultaneously, the parameters of hemorrheological indexes (HI), brain electrical activity map (BEAM) and transcranial Doppler sonography (TCD) were observed before and after treatment.</p><p><b>RESULTS</b>In Group B, the clinical GCS, the HI, the BEAM and the prognosis GOS were improved much more than those in Group A. And the TCD parameters in Group B decreased, which had significant difference compared with that in Group A (P<0.01).</p><p><b>CONCLUSIONS</b>Wilsonii injecta can rapidly improve the injured p ersons' conscious states, the abnormal BEAM and the surviving quality. It suggests that the improvement of the HI is related to the relief of the vasospasm of the arterial blood vessels in the brain, which may be one of the important mechanisms of wilsonii injecta in improving the prognosis.</p>

Repair effect of Schwann cells modified by microgene pSVPoMcat on injured spinal cord in rats / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To observe the repair effect of Schwann cells (SCs) modified by microgene pSVPoMcat on injured spinal cord in rats.</p><p><b>METHODS</b>Semi-transection injury at the level of T(8) of spinal cord was made with cutting method on 120 Sprague Dawley (SD) rats. Then 40 rats implanted with SCs modified by microgene pSVPoMcat were taken as Group A, 40 rats implanted with simple SCs as Group B and the other 40 rats were taken as the control group (Group C). The functional recovery of the rats was observed through combined behavioral score (CBS) and cortical somatosensory evoked potential (CSEP), and the expression of the glial fibrillary acidic protein (GFAP) was measured with in situ hybridization and immunocytochemistry. At 3 months after operation, the rats were examined with magnetic resonance image (MRI), and the neurofilaments (NF) of the axons were stained with immunohistochemical method.</p><p><b>RESULTS</b>GFAP expression in Group A was significantly lower than that of the other 2 groups. MRI showed that the spinal signals in the injured area recovered fundamentally in Group A, didn't recover in Group B and malacia focus was found in Group C, which was same as the results of NF staining. Wave amplitudes in incubation periods in Group A and Group B tended to recover. It recovered to the normal level in Group A, which was similar to the results of CBS.</p><p><b>CONCLUSIONS</b>SCs modified by microgene pSVPoMcat can inhibit GFAP expression, improve the growth of the axons and the functional recovery of neurons after spinal cord injury.</p>
