A novel therapeutic strategy utilizing EpCAM aptamer-conjugated gemcitabine for targeting bladder cancer and cancer stem cells.

Gemcitabine (GEM) is a first line chemotherapy drug for bladder cancer (BCa). GEM's lack of specificity has led to disadvantages, resulting in low efficiency, especially when combined with the targeted treatment of BCa stem cells (CSCs), which is considered the cause of BCa recurrence and progression. To enhance the anti-cancer effect and reduce the side effects of GEM targeting of BCa cells/CSCs, an aptamer drug conjugate (ApDC) targeted delivery system was used to improve the efficiency of GEM in BCa therapy using EpCAM aptamer-GEM conjugates based on the epithelial cell adhesion molecule (EpCAM), which is highly expressed on the cell membrane of BCa cells/CSCs.

Pharmacokinetics and Bioequivalence of 2 Products of Fluticasone Propionate Nasal Spray in Healthy Chinese Subjects.

Fluticasone propionate nasal spray is widely regarded as a first-line therapy for allergic rhinitis. To establish bioequivalence between the test and reference products of fluticasone propionate nasal spray, an open-label, randomized, single-dose, and 2-sequence crossover study was conducted on 84 healthy Chinese subjects under fasting conditions to determine the pharmacokinetic bioequivalence of the 2 products.

[Biological essence of blood stasis-heat syndrome in ischemic stroke and current research status of traditional Chinese medicine prevention and treatment based on thromboinflammation reaction].

Blood stasis-heat syndrome is one of the common syndromes of ischemic stroke, which is manifested as syndromes of blood stasis and heat during the pathological progression of patients with ischemic stroke, but there is a lack of systematic research on its biological essence. Thromboinflammation reaction is a newly proposed pathological mechanism highly associated with thrombosis and inflammatory reaction, and it refers to the fact that under the mediation of von Willebrand factor(vWF) and the kallikrein-kinin system, thrombosis and inflammatory reaction interact with each other. Activation of T cells and neutrophils further aggravates thrombosis and worsens the pathological progression of ischemic stroke.
