Objective:To investigate the curative effects and the economic effects of Alprostadil in Pharmacotherapeutic Schemes for Cerebral Infarction. Methods:118 cases of cerebral infarction, admitted from March 2001 to March 2003, were collected and divided into two groups: Alprostadil was given to group Ⅰ, Alprostadil was not given to group Ⅱ. Data was evaluated using the pharmacoeconomics cost effectiveness analysis. Results: The costs of two groups were 13 826.13 and 7 884.55 yuan respectively. The effective rates of two groups were 92.89% and 80.33% respectively. The cost-effective rates of two groups were 148.70 and 98.15 yuan / per unit of effective. It cost 469.69 yuan for group Ⅰ to increase per unit of effective above group Ⅱ. Conclusion: GroupⅡ had lower cost- effective ratio, and groupⅠ had higher effective rate. If patients care about effectiveness more than cost, it maybe useful to take groupⅠ.

Objective To observe the early rehabilitation effect of mild hypothermia on patients with herpes simplex viral encephalitis (HSE). Methods A total of 58 patients with HSE were randomized into two groups, a mild hypothermia therapy group (30 cases) and a normothermia control group (28 cases). Their rectal temperatures were controlled to (34±1)℃ and (37.0±0.5)℃ respectively. Serum levels of neuron specific enolase (NSE) were determined through radio-immunoassay (RIA). Soluble intercellular adhesion molecule-1 (sICAM-1) was measured with ELISA before and 1, 3, 5, and 7 d after treatment. The outcome was evaluated using the Glasgow Outcome Scale (GOS) 30 days after treatment. Results Compared with the normothermia control group, the mild hypothermia group's serum levels of NSE and sICAM-1 decreased quickly and significantly during the early stage of treatment and remained better 30 d later. Conclusion Mild hypothermia therapy can dramatically reduce inflamma-tion and facilitate the rehabilitation of damaged neurons, provide protective effects and improve the outcome for pa-tients with SHE.

Objective To investigate the analysis of collateral circulation in patients with acute symptomatic internal carotid artery occlusion (ICAO)and its clinical significance. Methods Seventy-two consecutive patients with symptomatic ICAO diagnosed by digital subtraction angiography (DSA)were enrolled retrospectively. The American Society of Intervention and Treatment Neuroradiology / Society of Interventional Radiology (ASITN/ SIR)scores were used to evaluate the collateral circulation in the region of ICAO,and the collateral circulation of the patients with different causes,different clinical manifestations, and different types of infarcts were compared. Results Of the 72 patients with ICAO,61(84. 7%)had atherosclerotic occlusion,8(11. 1%)had cervical dissection,and 3 (4. 2%)had cardioembolism;55 patients (76. 4%)had cerebral infarction and 17(23. 6%)had transient ischemic attack. There were no significant differences in the ASITN/ SIR scores among the different causes (P > 0. 05). The ASITN/ SIR scores in patients with cerebral infarction and transient ischemic attack were 2. 64 ± 0. 80 and 3. 29 ± 0. 69 respectively. There was significant difference (P < 0. 05). In patients with cerebral infarction,the ASITN/SIR scores in patients with internal watershed infarction and regional cerebral infarction only were 2. 43 ± 0. 68 and 2. 36 ±0. 51 respectively,they were lower than the patients with only external watershed infarction only and/ or cerebral infarction in cortical territory (3. 42 ±0. 90,P <0. 05). Conclusion Atherosclerotic occlusion is the most common cause of ICAO. ASITN / SIR scores may reflect the conditions of collateral circulation in patients with ICAO. The occurrence of internal watershed infarction and regional infarction indicates the collateral circulation is poor,and need for further therapeutic intervention.
