Summary of a Cochrane review: Wendan decoction traditional Chinese medicine for schizophrenia

Effect of Shi-Zhen-An-Shen herbal formula granule in the treatment of young people at ultra-high risk for psychosis: a pilot study

Introduction

To date, there is no conclusive evidence for early interventions on ultra-high risk (UHR) for psychosis. The Chinese herbal medicine is confirmed to be beneficial in improving psychiatric symptoms and cognitive impairments for schizophrenia patients. However, the effect of Chinese herbal medicine on treating UHR patients remains unknown.

Methods

Eighty UHR patients were recruited from the outpatient department. They were randomly assigned to receive either Shi-Zhen-An-Shen herbal formula granule (SZAS-HFG) combined with aripiprazole placebo or aripiprazole combined with SZAS-HFG placebo for a 12-week treatment. The psychiatric symptoms were assessed using the Structured Interview for Prodromal Syndromes (SIPS). The Trail Making Test part A (TMT-A), Brief Visuospatial Memory Test (BVMT), Hopkins Verbal Learning Test (HVLT), and Continuous Performance Test (CPT) were used to assess cognitive functions. we also employed the Global Assessment of Functioning (GAF) to evaluate social functioning. The linear mixed-effects models were performed to detect the difference in effectiveness between the two groups.

Results

After 12-week treatment, both groups showed significant effects of time on SIPS, TMT-A, HVLT, BVMT, and GAF. There was a significant effect of group only on CPT. Moreover, we also found a significant interaction effect on GAF.

Conclusion

SZAS-HFG can effectively alleviate psychosis symptoms, and improve cognitive impairments and overall functioning as well as aripiprazole.Clinical trial registration: Chinese Clinical Trial Registry, ChiCTR-IOR-17013513.

Efficacy and Safety of Wendan Decoction for Acute Brain Injury: A Randomized Controlled Study

Objectives: Despite the remarkable advances in critical care management of acute brain injury for the past 20 years, the prognoses remain poor. However, numerous reports indicate the efficacy of Traditional Chinese Medicine (TCM) therapy in stroke rehabilitation. This study aimed to determine the efficacy and safety of integrated TCM (Wendan decoction [WDD]) in patients with acute brain injury as a combination therapy in the early stages. Design: Prospective randomized controlled trial. Setting: Single-center study. Subjects: Sixty patients diagnosed with acute brain injury were randomly assigned to intervention and control groups, equally, and 41 patients completed the study. Interventions: All patients were treated by conventional neurologic intensive care. The 23 patients in the intervention group were administered with an integrated WDD in the early stages three times daily; combination treatment was initiated within 14 days and lasted >1 month. Outcome measures: Duration of ventilator use, intensive care unit stays, Glasgow Coma Scale (GCS) scores, motor response, the best muscle power, disability rating scale (DRS) scores, modified Rankin scale (mRS) scores, and the mortality rate for the first month. The other outcome measures were GCS scores, motor response, the best muscle power, DRS, mRS, and Barthel index (BI) scores 6 months later. Results: There was no mortality in the intervention group, but the rate was 39% in the control group for first month. Comparisons between groups showed significant differences (p < 0.05) in GCS, DRS, mRS, and BI scores, indicating improvements in the intervention group after 6 months. Conclusions: In the early stages of acute brain injury, combination treatment with WDD was found to be safe. Furthermore, this treatment may improve neurologic functional outcomes after 6 months.
