[Outcomes of early surgery combined with anti-vasospasm agents treat ruptured cranial aneurysms: an analysis of 127 cases].
Retrospective study on 127 cases of early microsurgery combined with antivasospasm agents for treatment of subarachnoid hemorrhage after the rupture of intracranial aneurysm. To evaluate the microsurgery for early-stage (3 days) of ruptured aneurysm. ⋯ Early operation could prevent second-time rupture effectively, lower the death rate, and at the same time lower the occurrence of cerebral vasospasm and the succeeding damage caused. Cerebral vasospasm is still the serious complication of subarachnoid hemorrhage of ruptured aneurysm and inappropriate management would cause critical consequences. Antivasospasm agents used postoperative could help preventing cerebral vasospasm and maintaining function.

[Effects of high thoracic epidural anesthesia on ventricular remodeling and expression of beta(3)-adrenoceptor in rats with heart failure induced by acute myocardial infarction].
To investigate the effect of high thoracic epidural anesthesia on ventricular remodeling and cardiac function in rats with heart failure induced by myocardial infarction, and to investigate their mechanism. ⋯ These results indicate that HTEA could ameliorate ventricular remodeling and cardiac function in rats with heart failure induced by myocardial infarction. The mechanism could involve decreases of beta(3)AR expression in rats of heart failure.

[Effects of positive end expiratory pressure ventilation upon respiratory function and hydrophobic surfactants proteins in rabbit with seawater respiratory distress syndrome].
To investigate the effects of positive end-expiratory pressure (PEEP) ventilation upon respiratory function and lung surfactant protein B (SP-B)/SP-C in seawater respiratory distress syndrome (SW-RDS) rabbit. ⋯ PEEP ventilation can improve the oxygenation indices and lung compliance in SW-RDS animals. And such an effect is correlated with both the mRNA expressions of SP-B/SP-C and mechanical distension.

Comparative Study[Dose distributions of proton beam therapy for hepatocellular carcinoma: a comparative study of treatment planning with 3D-conformal radiation therapy or intensity-modulated radiation therapy].
A comparative dose distribution study has been undertaken between proton beam therapy (PBT), 3-dimensional conformal radiation therapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) in the treatment of hepatocellular carcinoma (HCC), so as to assess the potential advantages of PBT. ⋯ Compared with 3D-CRT, PBT reduced the dose to the normal liver tissues and nonliver OARs significantly, even with 20 to 30.3 percent of dose escalation. Compared with IMRT, PBT reduced the dose to the normal liver tissues significantly, even with 20 to 30.3 percent of dose escalation. PBT reduced the dose to the right kidney and stomach significantly. No significant difference was observed respect to the dose to spinal cord.
