Clinical Study on Modified Guipitang Combined with Xuefu Zhuyutang in Treating Mild Cognitive Impairment After Cerebral Infarction / 中国实验方剂学杂志

ABSTRACT

ObjectiveTo observe the clinical efficacy and anti-inflammatory and anti-oxidant effect of modified Guipitang combined with Xuefu Zhuyutang in the treatment of mild cognitive impairment （MCI） after cerebral infarction with syndromes of heart and spleen deficiency and blood stasis blocking collateral. MethodA total of 114 eligible patients were randomly divided into a control group and an observation group，with 57 cases in each group. Patients in the control group were given red deer ginseng tablets （po），4 tablets/time，2 times/day. Patients in the observation group were given modified Guipitang combined with Xuefu Zhuyutang （po，1 dose/day）for continuous 8 weeks. This study compared the scores of montreal cognitive assessment （MoCA） scale，Rivermead behavioral memory test （RBMT），activities of daily living （ADL），trail making test B （TMT-B），neuropsychiatric inventory questionnaire （NPI） and scores of traditional Chinese medcine（TCM） syndrome with syndromes of heart and spleen deficiency and blood stasis blocking collateral before and after treatment. Then we further detected the levels of 8-hydroxydeoxyguanosine （8-OHDG），malondialdehyde （MDA），oxidized low density lipoprotein （ox-LDL），superoxide dismutase （SOD），homocysteine （Hcy），interleukin-8 （IL-8），C-reactive protein （CRP） and fibrinogen （FIB） levels before and after treatment. ResultThe total effective rate for the treatment of cognitive function impairment in the observation group was 92.98% （53/57），which was higher than 78.95% （45/57） in the control group （χ2＝4.653，P<0.05）. The recovery rate of cognitive function in the observation group was 54.39% （31/57），which was higher than 33.33% （19/57） in the control group （χ2＝5.130，P<0.05）. The MoCA，RBMT and ADL scores of the observation group were higher than those of the control group （P<0.01），and the TMT-B time of the former was shorter than that of the latter （P<0.01）. In addition， the observation group showed lower scores of TCM syndrome，NPI-1 and NPI-2 scores than the control group （P<0.01）. The SOD level of the observation group was higher than that of the control group （P<0.01），and the levels of 8-OHDG，ox-LDL，MDA，Hcy，IL-8，CRP and FIB were lower than those of the control group （P<0.01）. ConclusionModified Guipitang combined with Xuefu Zhuyutang can improve cognitive function in MCI patients after cerebral infarction with syndromes of heart and spleen deficiency and blood stasis blocking collateral， with anti-inflammatory and anti-oxidant effect， and yield superior efficacy than red deer ginseng tablets.
