Abstract:
ObjectiveTo evaluate the clinical efficacy of Zuogui Pill (左归丸,ZGP) decoction on neurological function, motor function, and activities of daily living in patients with ischemic stroke (IS) of liver-kidney yin deficiency syndrome, and to assess its potential mechanisms from the perspectives of cerebral perfusion and corticospinal tract (CST) remodeling. MethodsA total of 108 patients with IS of liver-kidney yin deficiency syndrome and onset time ≤14 days were enrolled and randomly divided into a control group and a treatment group, with 54 cases in each group. The control group received conventional western medicine, while the treatment group received ZGP decoction (one dose per day) in addition to the conventional treatment. Both groups were treated for 90 days. The National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), modified Barthel Index (MBI), Fugl-Meyer Assessment (FMA), and Chinese medicine syndrome score (CMS) were evaluated before treatment and after (90±3) days of treatment. Three-dimensional arterial spin labeling (3D-ASL) and diffusion tensor imaging (DTI) were performed to obtain ipsilesional cerebral blood flow (CBF) in the unaffected and affected hemispheres, relative CBF (rCBF), and fractional anisotropy (FA) of the CST. Nodal analysis of FA values along the CST was also conducted. Correlation analysis was used to assess the relationships between post-treatment cerebral perfusion parameters (CBF and rCBF), and FA values with clinical neurological function scores. ResultsAfter treatment, both groups showed significantly decreased NIHSS, mRS and CMS scores, together with significantly increased FMA and MBI scores (P<0.01). Intergroup comparison showed that NIHSS, mRS, and CMS scores in the treatment group were significantly lower than those in the control group , while MBI and FMA scores were significantly higher (P<0.01). The 3D-ASL results revealed that CBF and rCBF values in the affected hemisphere significantly increased in both groups after treatment, and the treatment group had significantly higher values (P<0.01). DTI showed that the FA value of the CST on the affected side in the treatment group was significantly higher than that in the control group after treatment (P<0.05). Nodal analysis along the CST further demonstrated that the continuity of FA values at lesion-related nodes 45~99 in the treatment group was significantly better than that in the control group (P<0.01), with significant increases at nodes 65~71 and 76~81 compared with baseline (P<0.05 or P<0.01), whereas the control group showed a decreasing trend at nodes 80~93 (P<0.05). Correlation analysis indicated that CBF and rCBF values in the affected hemisphere were negatively correlated with NIHSS and mRS scores and positively correlated with MBI score (P<0.05). FA value of the CST on the affected side, both before and after treatment, were negatively correlated with NIHSS score and positively correlated with FMA score (P<0.05 or P<0.01). ConclusionZGP decoction can effectively improve neurological function, motor function, and activities of daily living in IS patients with liver-kidney yin deficiency syndrome, and its mechanism may be related to enhanced cerebral perfusion in the affected hemisphere and corticospinal tract structural remodeling.
