Objective To investigate the treatment for severe hypertensive intracerebral hemorrhage (SHIH). Methods Between May 1997 and December 2003 A total of 110 cases of SHIH were divided into two groups with 55 cases in each group: Conservative Group (Control Group) was treated by medical conservative management, and Minimally Invasive Group was given a combination therapy of minimally invasive puncture and drainage, infusion with urokinase, and intravenous dripping of ?-aescine sodium. Results In the Minimally Invasive Group, the rate of significant improvement, the total effective rate, and the death rate were 81.8% (45/55), 89.1% (49/55), and 10.9% (6/55), respectively. The corresponding values in the Control Group were 32.7% (18/55), 49.1% (27/55), and 43.6% (24/55), respectively. The curative effect in the Minimally Invasive Group was superior to that in the Control Group (?2=20.604, P=0.000). Conclusions[WTBZ] The combination therapy of minimally invasive puncture and drainage, infusion with urokinase, and intravenous administration of ?-aescine sodium in the treatment of severe hypertensive intracerebral hemorrhage is simple, safe, and effective. The treatment has fewer complications and significantly improves the prognosis of patients.

Objective To assess the value of enhanced multislice spiral CT (MSCT) scan using fat-dense enema for the staging of colorectal carcinoma.Methods 33 cases with colorectal carcinoma confirmed by colonoscopy were examined by enhanced MSCT scan ,from the dome of the diaphragm to symphysis pubica,after bowel cleaning,administration of smooth muscle relaxant, and rectal fat-dense contrast agent insuffation .Carcinomas were staged with TNM by axial,multiplannar reconstruction(MPR) and CT virtual endoscopy (CTVE) images.
