目的
2
探讨通脑益智方治疗非痴呆型血管性认知障碍(VCIND)脾肾亏虚、痰瘀阻络证患者的作用机制。
方法
2
92例VCIND脾肾亏虚、痰瘀阻络证患者随机分为治疗组50例和对照组42例。两组均予常规基础治疗,对照组联合口服多奈哌齐片,每次5 mg,每晚1次;治疗组联合通脑益智方,每日1剂,水煎分早晚两次口服。两组均连续治疗3个月。治疗前后比较两组患者简易精神状态检查量表(MMSE)评分、血管性痴呆评估量表(VaDAS-Cog)评分、日常生活能力量表(ADL)评分、中医证候评分(主症包括思维呆滞、善忘无记、性情改变、语言错乱,次症包括腰膝酸软、头晕头痛、耳鸣时作、神疲乏力、肢体困重、失眠烦躁、纳呆脘胀、面部发麻)。比较两组患者肠道菌群多样性和菌群丰度结构的变化及粪便中短链脂肪酸(SCFAs)水平(包括乙酸、丙酸、丁酸、异丁酸、异戊酸、戊酸、己酸)。并纳入同期20例健康受试者粪便相关数据作为参照。研究过程中进行安全性观察。
结果
2
与本组治疗前比较,两组患者治疗后MMSE评分升高,VaDAS-cog评分降低(
P
<0.05或
P
<0.01),治疗组ADL评分较治疗前升高(
P
<0.05)。两组患者治疗后思维呆滞、善忘无记、性情改变、语言错乱、肢体困重、失眠烦躁、纳呆脘胀、面部发麻评分及中医证候总积分均较治疗前明显降低(
P
<0.05或
P
<0.01);治疗后组间比较,治疗组腰膝酸软、耳鸣时作、神疲乏力、肢体困重、失眠烦躁、纳呆脘胀评分较对照组明显下降(
P
<0.05或
P
<0.01)。肠道菌群多样性结果显示,治疗组Shannon指数较治疗前升高(
P
<0.05)。治疗后各样本在主坐标分析图上经Anosim分析比较差异有统计学意义(
P
<0.01),提示两组间物种发生改变。治疗后,治疗组拟杆菌门和梭杆菌门相对丰度上升,放线菌门、疣微菌门和蓝藻菌门等相对丰度下降(
P
<0.05),普拉梭菌属、双歧杆菌属、乳酸杆菌属、瘤胃球菌属相对丰度明显升高(
P
<0.05)。两组患者治疗后与健康人群肠道菌群物种多样性比较,治疗组人群的肠道菌群结构向健康受试者靠近,而对照组无此趋势。治疗组治疗后乙酸、丙酸、丁酸均较治疗前升高(
P
<0.05或
P
<0.01)。
结论
2
通脑益智方可改善VCIND脾肾亏虚、痰瘀阻络证患者的认知能力和生活质量,调节肠道微生态可能是其作用机制之一。
Objective
2
To observe the clinical efficacy and mechanism of
Tongnao Yizhi Formula
(通脑益智方, TYF) in treating vascular cognitive impairment no dementia (VCIND) with spleen and kidney depletion, phlegm and stasis obstructing collaterals syndrome.
Methods
2
Ninety-two VCIND patients with spleen and kidney depletion, phlegm and stasis obstructing collaterals syndrome were randomly divided into control group (42 cases) and treatment group (52 cases). Both groups received routine basic treatment. The control group was given donapezil hydrochloride capsules orally, 5 mg each time, once at night, while the treatment group was given TYF orally, 1 dose per day. Both groups were treated continuously for 3 months. The scores of Mini-Mental State Examination (MMSE), Vascular Dementia Assessment Scale-Cognitive Subscale (VaDAS-Cog), Activity of Daily Living Scale (ADL), and TCM syndrome scores (the primary symptoms such as sluggish thinking, forgetfulness, temperament changes, and language confusion, and secondary symptoms such as weakness of waist and knees, dizziness and headache, occasional tinnitus, fatigue, heaviness of limbs, insomnia and irritability, poor appetite and abdominal distension, numbness of face) were observed before and after treatment in both groups. The changes in gut microflora diversity and flora abundance structure as well as fecal short-chain fatty acids (SCFAs) levels including acetic acid, propionic acid, butyric acid, isobutyric acid, isovaleric acid, valeric acid, and caproic acid were compared between groups. The feces of 20 healthy subjects in the same period were included as reference. Safety was evaluated during the study.
Results
2
After treatment, both groups exhibited significant increases in MMSE scores and decreases in VaDAS-cog scores (
P
<0.05 or
P
<0.01), and ADL scores in the treatment group significantly increased (
P
<0.05). Scores of symptoms including sluggish thinking, forgetfulness, temperament change, language confusion, heaviness of limbs, insomnia, irritability, poor appetite, abdominal distension, and facial numbness as well as the total score significantly decreased in both groups after treatment (
P
<0.05 or
P
<0.01). When compared between groups, the treatment group showed substantial reductions in scores of weakness of waist and knees, tinnitus, fatigue, heaviness of limbs, insomnia, irritability, loss of appetite and abdominal distension (
P
<0.05 or
P
<0.01). The gut microflora diversity analysis showed that the Shannon index of the treatment group significantly increased after treatment (
P
<0.05).PCoA analysis and ANOSIM test indicated significant differences between groups, suggesting changes in microflora species (
P
<0.01). After treatment, the relative abundance of Bacteroidetes and Fusobacteria in the treatment group increased, while the relative abundance of Actinobacteria, Verrucomicrobia and Cyanobacteria decreased (
P
<0.05); the relative abundance of Faecalibacterium prausnitzii, Bifidobacterium, Lactobacillus, a
nd Ruminococcus increased significantly (
P
<0.05). Compared to the the gut microflora species diversity of the healthy people, it is indicated that the gut microflora structure in the treatment group was close to that of the healthy people, while there was no such trend in the control group. In the treatment group, acetic acid, propionic acid, and butyric acid in the treatment group were all higher after treatment (
P
<0.05 or
P
<0.01).
Conclusions
2
TYF can improve the cognitive ability and quality of life of VCIND patients with spleen and kidney depletion, phlegm and stasis obstructing collaterals syndrome, and this improvement may be related to regulating intestinal microecology.
