Abstract
Objective: Erythropoietin (EPO) for treating acute ischemic stroke (AIS) has been investigated in many studies. However, the evidence was inconsistent. Thus, a systematic review and metaanalysis were performed to elucidate the role of EPO in treating patients with AIS.
Methods: Two electronic databases (PubMed and EMBASE) were used. 30-day NIHSS measures primary outcome while all-cause mortality in the follow up and 90-day Barthel Index were regarded as secondary outcome. Results are presented as relative risk (RR), standardized mean difference (SMD) and 95% confidence intervals (CI). We employed Stata software to perform the meta-analysis. Results: Four randomized controlled trials (RCTs) involving 784 patients were contained in this metaanalysis. The total combined results on 30-day NIHSS were (SMD = -0.52, 95% CI: -1.39, 0.34) with random-effects model and sensitivity analysis showed a significant difference after excluding the Ehrenreich 2009 trial. The total combined secondary measured results were (RR=1.72, 95% CI: 1.10, 2.70) and (SMD = 0.01, 95% CI: -0.14, 0.16) for all-cause mortality and 90-day Barthel Index. In the subgroup analysis by using recombinant tissue plasminogen activator (rtPA) earlier, the rtPA group showed increased all-cause mortality with the result of (RR = 1.92, 95% CI: 1.04, 3.52), but not in non-rtPA group. Conclusion: To our systematic review and meta-analysis, we didn’t recommend EPO administration for patients with AIS, especially with the combination of rtPA. Large RCTs are warranted to examine EPO efficacy in AIS patients in the future.Keywords: Acute ischemic stroke, erythropoietin, meta-analysis, randomized controlled trials, recombinant tissue plasminogen activator, systematic review.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities.
