Spatiotemporal Evolution of Traditional Chinese Medicine Mechanisms in Acute Ischemic Stroke Treated With Dengzhan Xixin and Dengzhan Shengmai (STEM-DZ)

11 de maio de 2026 atualizado por: Cheng xiao, Guangdong Provincial Hospital of Traditional Chinese Medicine
To integrate large-scale RCT data on clinical symptoms, TCM syndromes, prognosis, and multi-omics profiles, construct a spatiotemporal dynamic network for disease-syndrome evolution of acute ischemic stroke (AIS) in the acute and recovery phases, evaluate the efficacy and safety of sequential treatment with Erigeron breviscapus-Dengzhan Shengmai for AIS, and provide evidence for precise syndrome differentiation and individualized therapy.Secondary Objective:To investigate the optimal time window and key intervention targets of sequential treatment with Erigeron breviscapus-Dengzhan Shengmai for AIS.

Visão geral do estudo

Descrição detalhada

This study is a randomized (1:1), double - blind, multicenter, parallel - controlled clinical trial. It plans to recruit 358 patients with acute ischemic stroke (AIS). The research period is 3 months. After the blind is unmasked in the third month, an exploratory clinical study will be carried out and the patients will be observed for 6 months. The purpose of the study is to explore the spatio - temporal evolution law, efficacy, and safety of the sequential treatment of AIS with "Erigeron breviscapus - Dengzhan Shengmai". After all the selected patients sign the informed consent form and meet the inclusion/exclusion criteria, they will be randomly assigned to the experimental group or the control group at a ratio of 1:1 through the central randomization system (IWRS):

Experimental group:

Acute phase (0 - 7 days after onset): 40 mL of Erigeron breviscapus injection diluted with 250 mL of normal saline, administered by intravenous drip once a day; Recovery phase (8 - 90 days): 2 capsules of Dengzhan Shengmai capsules (0.18 g per capsule), taken orally three times a day.

Control group:

Acute phase (0 - 7 days after onset): 250 mL of normal saline, administered by intravenous drip once a day; Recovery phase (8 - 90 days): 2 placebo capsules (starch, 0.18 g per capsule), taken orally three times a day.

All groups will receive basic treatment, including anti - platelet (aspirin/clopidogrel), blood pressure, blood lipid, and blood glucose control and other relevant treatments as stipulated in the guidelines.

Safety and compliance assessments will be conducted at the first administration and in the first week of treatment; researchers will also provide medication guidance. Subsequently, safety assessments and follow - ups will be carried out at 30±7 days and 90±7 days; efficacy assessments and follow - ups will be carried out at 48 hours, 7 days, 30±7 days, 90±7 days, and 180±7 days.
