Efficacy and Safety of Panax notoginseng Saponins in the Treatment of Adults With Ischemic Stroke in China: A Randomized Clinical Trial.

Importance: Preclinical and clinical studies have suggested the neuroprotective effect of Panax notoginseng saponins (Xuesaitong soft capsules). However, robust evidence in patients with ischemic stroke is lacking. Objective: To assess the efficacy and safety of Xuesaitong soft capsules in patients with ischemic stroke. Design, Setting, and Participants: This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted at 67 tertiary health centers in China from July 1, 2018, to June 30, 2020. Included patients were aged 18 to 75 years with a diagnosis of ischemic stroke and a National Institutes of Health Stroke Scale score between 4 and 15. Interventions: Eligible patients were randomly assigned within 14 days after symptom onset to receive either treatment with Xuesaitong soft capsules (120 mg orally twice daily) or placebo (120 mg orally twice daily) for 3 months. Main Outcomes and Measures: The primary outcome was functional independence at 3 months, defined as a modified Rankin Scale score of 0 to 2. Results: Among 3072 eligible patients with ischemic stroke who were randomized, 2966 (96.5%) were included in the modified intention-to-treat cohort (median [IQR] age, 62 [55-68] years; 1982 male [66.8%]). The number of patients who achieved functional independence at 3 months was 1328 (89.3%) in the Xuesaitong group and 1218 (82.4%) in the control group (odds ratio, 1.95; 95% CI, 1.56-2.44; P < .001). In the safety cohort, serious adverse events occurred in 15 of 1488 patients (1.0%) in the Xuesaitong group and 16 of 1482 (1.1%) in the control group (P = .85). Conclusions and Relevance: In this randomized clinical trial, Xuesaitong soft capsules significantly increased the likelihood of functional independence at 3 months in patients with ischemic stroke, indicating that this may be a safe and effective alternative therapy to improve prognosis in this population.

Individualized management of hepatic diseases in hereditary hemorrhagic telangiectasia.

Liver involvement in patients with hereditary hemorrhagic telangiectasia (HHT) has not been fully characterized in China. The clinical manifestations, imaging studies, results of treatment in six patients and symptomatic liver involvement were analyzed. Patients included three women and three men with age from 35 to 62 years old. Two patients presented with shortness of breath, one patient with anemia and splenomegaly, and one with chronic gastrointestinal bleeding; the remaining two were asymptomatic. CT and CT angiography (CTA) showed arterioportal and arteriovenous shunting in liver. CTA showed at least one enlarged hepatic artery in all patients. One patient received ligation of the enlarged arteries with subsequent disappearance of symptoms at 56-month follow-up. The patient with gastrointestinal bleeding received interventional embolotherapy and resolved; interventional therapy to embolize the enlarged hepatic arteries was unsuccessful in another patient and the patient died of heart failure and liver dysfunction 38 months later. The patient with splenomegaly received a splenectomy and bandage of an enlarged hepatic artery. One of the two patients with no symptoms died of liver dysfunction 41 months after diagnosis. The other showed abnormal liver function and ascites, and traditional Chinese medicinal herb was used with no effect 21 months later. The symptoms disappeared after systemic medical treatment. Individualized and active therapy is advantageous and proper for patients with HHT.
