Objective To investigate the safety and efficacy of low-dose recombinant tissue plasminogen activator (rtPA) in Chinese patients with acute ischemic stroke. Methods Consecutive patients with acute ischemic stroke received rtPA intravenous thrombolysis within 4. 5 h after symptom onset were enrol ed retrospectively. According to the dosage of rtPA, they were divided into either a low-dose group (0. 5-0. 8 mg/kg, the maximum dose 50 mg) or a standard dose group (0. 9 mg/kg, the maximum dose 90 mg). The incidences of symptomatic intracranial hemorrhage ( sICH) ( the National Institute of Neurological Disorders and Stroke [NINDS], and European Cooperative Acute Stroke Study Ⅱ [ECASSⅡ] , European Safe Implementation of Thrombolysis in Stroke-Monitoring Study [ SITS-MOST ] ), 90 d mortality, 90 d good outcome (the modified Rankin Scale [mRS] score 0-1), and life self-care ability (mRS score 0-2) were compared between the two groups. Results A total of 163 patients were enrol ed, including 74 patients in the low-dose group and 89 in the standard dose group. The constituent ratios of hypertension (44. 6% vs. 68. 5%; χ2 =9. 490, P=0. 002) and diabetes (5. 4% vs. 28. 1%; χ2 =14. 216, P<0. 001) in the patients of the low-dose group were significantly lower than those of the standard group, while the constituent ratios of smoking (56. 8% vs. 38. 2%; χ2 =5. 590, P=0. 018 ) and smal artery occlusive stroke (21. 6% vs. 10. 1%; χ2 =4. 122, P=0. 042 ) in patients of the low-dose group were significantly higher than those of the standard group. After adjusting for age, National Institutes of Health Stroke Scale (NIHSS) score, hypertension, diabetes, smoking, and ischemic stroke typing, multivariate binary logistic analysis showed that there were no significant differences in NINDS defined sICH (10. 8% vs. 9. 0%, odds ratio [OR] 1. 077, 95%confidence interval [CI] 0. 338-3. 436), ECASS Ⅱdefined sICH ( 9. 5% vs. 9. 0%; OR 0. 976, 95% CI 0. 296- 3. 221 ), SITS-MOST defined sICH (8. 1% vs. 4. 5%; OR 2. 269, 95% CI 0. 522-9. 852), 90 d mortality (17. 6% vs. 14. 6%; OR 1. 720, 95% CI 0. 578-5. 119), 90 d good outcome (35. 1% vs. 32. 6%;OR 0. 780, 95% CI 0. 356-1. 709), and life self-care ability (48. 6% vs. 42. 7%;OR 0. 936, 95% CI 0. 441-1. 987) between the 2 groups (al P>0. 05). Conclusions The program of intravenous thrombolysis for the treatment of Chinese patients with acute ischemic stroke with low-dose rtPA is safe and effective.

Objective To investigate the mechanism of mastoparan-1 (MP-1) antagonizing lipopolysaecharide (LPS) in vitro. Methods The affinity of MP-1 for lipid A was assayed by biosensor, and the neutralization of MP-1 on LPS (2 μg/L) was detected by kinetic turbidimetric limulus test. After exposing fluorescin isothiecyanate (FITC) labeled LPS (FITC-LPS) to MP-1 at different concentrations (5, 10, 20, 40 μmol/L), the binding of FITC-LPS to murine RAW264.7 cells was analyzed by laser scanning confocal microscopy. The influence of MP-1 on TLR4 expression in RAW264.7 cells stimulated by LPS (100 μg/L) was detected by immunoeytochemieal staining. The expressions of TLR4, TNF-α and IL-6 at the gene and protein level were detected by RT-PCR and ELISA after exposing LPS (100 μg/ L) stimulated RAW264.7 cells to MP-1 at different concentrations. The effect of MP-1 on the viability of RAW264.7 cells was detected by MTT assay. Results MP-1 had high affinity to lipid A and could neutralize LPS. MP-1 at 10 μmol/L significantly inhibited not only binding of FITC-LPS to RAW264.7 (P < 0.05), but also protein and gene expressions of TLR4, TNF-α and IL-6 in LPS stimulated RAW264.7 cells in a dose-dependent manner (P < 0.05). No toxic effect of MP-1 on the viability of RAW264.7 cells was found (P > 0.05). Conclusions MP-1 inhibits cell viability mediated by LPS, which may be related to its neutralization of LPS and inhibition of binding of LPS to RAW264.7 cell membrane receptors.
