RESUMO
<p><b>OBJECTIVE</b>To study the effect and mechanism of Tianhuang Granule (, THG) on: hydrocephalus in the patients with acute cerebral hemorrhage (ACH) through intracranial pressure (ICP) monitoring, serum matrix metalloproteinase-9 (MMP-9) level observation, and National Institutes of Health Stroke Scale (NIHSS) scoring (for nerve function de ficit).</p><p><b>METHODS</b>Sixty patients with ACH were equally randomized: into two groups by lottery, the control group and the THG group; all were treated with conventional therapy, but to the patients in the THG group, THG was given orally in addition for 28 days. Changes of ICP, MMP-9 expression, and NIHSS scores, as well as the degree of cerebral hematoma and hydrocephalus (by cranial CT scanning) in the patients, were estimated and compared.</p><p><b>RESULTS</b>(1) ICP was lowered more significantly in the: THG group, showing a significant difference between groups on day 7 (P<0.05). (2) MMP-9 expression was down-regulated in the THG group more significantly and earlier than that in the control group. (3) The degrees of cerebral hematoma and hydrocephalus in the THG group on day 7 were reduced significantly as compared with those on day 3 (P<0.05), but in the control group, the day of significant reduction was delayed to day 14, and the degrees on day 7 and day 14 in the two groups were significantly different (P<0.05 and P<0.01). (4) NIHSS score was significantly lower in the THG group than that in the control group on day 14 and day 28 (P<0.05 and P<0.01).</p><p><b>CONCLUSION</b>THG can effectively lower ICP, down-regulate MMP-9 expression, promote the absorption: of cerebral hematoma and hydrocephalus, and improve the nerve function, showing a clinical effectiveness than conventional therapy.</p>
