Daphnetin

The purpose of this clinical trial is to understand and evaluate the clinical efficacy and safety of Daphnetin Capsule in patients with vascular cognitive impairment. Changes in the Vascular Dementia Assessment Scale-cog(VADAS-cog) at 6 months were evaluated. Although Daphnetin has a dual neurovascular protective effect, however, there is still a lack of relevant high-quality studies on its role in patients with vascular cognitive impairment, especially in patients with vascular cognitive impairment in non-dementia (VCI-ND), whether it has a role in improving cognitive status needs to be urgently explored in high-quality clinical studies. Researchers are comparing Daphnetin to placebo (a drug-free analog) to see if Daphnetin is effective in treating vascular cognitive impairment. Participants will take either Daphnetin or placebo daily for six months, with follow-up visits every three months and completion of a case report form.

This clinical trial is designed to learn more about treating patients with lower limb lymphoedema following gynaecological surgery. The main question to be answered is To evaluate the efficacy of Daphnetin capsule in the treatment of patients with lower limb lymphedema following gynaecological malignancy surgery. Participants will take Daphnetin capsule 150mg tid (3 capsules/time, 3 times daily) orally at the same time as gradient compression stocking treatment. Researchers will compare 150mg Forte tablets (2 capsules/time, 2 times daily) and gradient compression stockings to see if Daphnetin capsule can be used to treat patients with lower extremity lymphedema following gynaecological malignancy surgery.
