Résumé
Objective To evaluate the efficacy of minimally invasive drairage of hematoma in treatment of hypertensive cerebral hemorrhage. Methods 60 patients with hypertensive cerebral hemorrhage were randomly divided into two groups,including the observation group of minimally invasive hematoma drainage, the control group 30 cases, a small bone window intracranial hematoma,observe and compare the two groups of hypertensive cerebral hemorrhage the neurological function recovery. Results The operative time was significantly shorter than that used in the control group. Postoperative mortality, the difference was significant (P <rate,the difference was significant( P < 0.05 ). Hematoma drainage time of the observation group was significantly shorter than that in the control group,two groups of neural function in SSS score comparison showed that 21 daysafter treatment ,SSS score in observation group was significantly higher in the observation group than the control group. Observation group MRS scores and BI scores were significantly improved, and the ADL rating was significantly beffer than the control group( P < 0.05 or P < 0.01 ). Conclusion The minimally invasive hematoma drainage in the treatment of hypertensive cerebral hemorrhage with a short time, could significantly promote the recovery of neurological function in patients and reduce patient complications and mortality ,but also be neficial to activities of daily living (ADL) recovery.
Résumé
Hemodynamic study of L-THP in anaesthetized rats showed that 6 mg/kg iv decreased only blood pressure (BP) significantly, and decreased left ventricular pressure ( LVP ) temporarily. At the dose of 18 mg/kg, L-THP lowered the BP, LVP, ? ( dP/dt ) max, ( dP/dt ) P-1 and HR. But the degrees o?diminutions of BP were greater than that of cardiac contractility. The inhibitory percentage of L-THP on DAP was greater than that of SAP. In addition, the extent of decrease of DAP was shown dose dependently. The results suggest that L-THP reduces the peripheral vessel resistance, and it inhibits the cardiac contractibility in high dosage.
Résumé
The antagonistic effects of L-THP, Ver and Pap to contraction of isolated guinea pig trachea preparations induced by BaCl2 10-3mol/L ,KC1 3?10-2mol/L, 5-HT 2?10-5mol/L, Ach 2?10-5mol/L and His 2? 10-5mol/L were studied.The antagonistic effects of L-THP were different from Ver and Pap. The IC50 value of L-THP for contraction induced by BaCl2, KC1, 5-HT and His was 3 .5? 10-5mol/L , 4.5 ? 10-5mol/L , 2.5?10-3 mol/L and 8.9? 10-5mol/L respectively. It was showed that sensibility of several agonists to inhibition by L-THP was correlated with dependence of extracellular Ca2+. The potencies of L-THP on anti-KCl and anti-5-HT actions were similar. The results suggested that LTHP possesses anti-calcium and anti-5-HT action on guinea pig trachea.
