ABSTRACT
Objective To investigate the mechanism of action of Huzhang Qingmai decoction (HZQMY) on the improvement of cognitive function in mice with chronic cerebral ischemia from the perspective of intestinal flora. Methods A mouse model of chronic cerebral ischemia was established by placing microcoils around the bilateral common carotid arteries to induce bilateral carotid artery stenosis (BCAS). After 12 weeks of intragastric administration, the cognitive function of the mice was measured by the Morris water maze; the myelin damage was analyzed by LFB staining; The contents of the cecum of the mice in each group were extracted and analyzed by 16S rRNA sequencing. Results The results of the water maze experiment showed that the mice in the HZQMY group had a significantly shorter escape latency, increased the number of crossings platform and the percentage of target quadrants. LFB staining showed that the white matter damage in the model group was severe; the white matter damage in the HZQMY group was milder. The results of 16S rRNA sequencing showed that compared with the model group, the abundance of Verrucomicrobiota, Akkermansia, and ErysiPelatoclostridium capsulatum in the intestinal flora in HZQMY group was significantly reduced (P<0.05), while the abundances of Eubacterium_xylanoPhilum and Allobaculum were significantly increased (P<0.05). Conclusion The protective effect of HZQMY, which has the effect of improving cognitive function in mice with chronic cerebral ischemia, may be related to the regulation of intestinal flora in mice with chronic cerebral ischemia.
ABSTRACT
Objective To explore the mechanism of motherwort in the treatment of nerve injury. Methods The active components of motherwort were obtained by searching TCMSP and BATMAN-TCM databases. The action targets of candidate compounds were collected and predicted from TCMSP and SwissTargetPrediction (STP) databases. The target genes corresponding to the active components of motherwort were obtained by using the standardized database of disease targets (Uniprot). The potential targets of motherwort in the treatment of nerve injury were obtained by mapping the disease genes of nerve injury with the three databases of Genecards, DisGenet and OMIM. The network topology analysis software Cytoscape 3.6.0 was used to construct the action target network of motherwort active components. The protein interaction platform database (STRING) was used to construct the interaction relationship between action targets. The target protein interaction (PPI) network was constructed by introducing Cytoscape 3.6.0 software. Through STRING database, GO enrichment analysis and KEGG pathway enrichment analysis were carried out to analyze the target points of motherwort in the treatment of nerve injury. Results 19 active components were screened from motherwort, involving 654 action targets, including 426 action targets related to nerve injury and 6 key targets. These target genes were mainly involved in biological regulation, oxidative stress response and cell communication and other biological processes. Molecular functions were mainly related to protein binding, ion binding and catalytic reduction. They were enriched outside the cell membrane. Its mechanism was related to signal pathways such as MAPK, Toll-like receptor, PI3K-Akt, TNF, IL-17, and apoptosis. Conclusion The active components of motherwort may play a protective role on nerve injury through anti-inflammation, anti-apoptosis and promoting cell growth.
ABSTRACT
OBJECTIVE:To observe the clinical efficacy and safety of flunarizine combined with salvianolate in the treatment of acute migraine. METHODS:A total of 72 patients with acute migraine were randomly divided into control group(36 cases)and observation group (36 cases). Based on routine treatment,control group was given Flunarizine hydrochloride capsules orally,10 mg for 65 year-old and below once a day,5 mg for more than 65 year-old once a day. Observation group was additionally given Flunarizine hydrochloride for injection 200 mg intravenously,once a day,on the basis of control group. Both groups were treated contineously till cured or for 2 weeks. Clinical efficacy,onset time,recovery time,VAS score,frequency and duration of head-ache attack,ADR were observed in 2 groups. RESULTS:In the course of treatment,the two groups did not terminate and fall off, and all of them completed the treatment. The total response rate(97.22%)of observation group was significantly higher than that (86.11%)of control group;onset time and recovery time of observation group were both shorter than those of control group,with statistical significance (P0.05). After treatment,VAS score,frequency and duration of headache attack in 2 groups were all significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P0.05). CONCLU-SIONS:Based on routine treatment,flunarizine hydrochloride capsules combined with Salvianolate injection show significant effica-cy for acute migraine with good safety.
ABSTRACT
ObjectiveTo observe the subcutaneous and intraperitoneal insulin injection's effect of the level of oxygen free radicals of type 2 diabetes model.MethodsC57BL/6J mice were chosen as normal control group (C group,n=9).KK mice were randomly divided into intraperitoneal injection of insulin group (i.p.group,n=9),the subcutaneous insulin group (s.c.group,n=9) and untreated group (U group,n =9).The i.p.group and the s.c.groups were given certain amount of insulin (insulin injecta and protamine insulin injecta by volume ratio of 2:1 mixture)for one month,maintained the GLU at normal levels (6±1.5) mmol/L.SOD,GSH-PX activity and MDA content of serum,liver,kidney and heart in each group were detected.Results The liver,kidney,heart and serum's SOD and GSH-PX activity significantly reduced and MDA content significantly increased in the U group.Both kinds of delivery methods could increase serum SOD and GSH-PX activity and reduce the content of MDA to the normal control group level,but the intraperitoneal injection had stronger effect.Two kinds of delivery methods could both reduce the MDA content of liver,and had almost the same effect; but the subcutaneous injection group had better effect on increasing the liver's SOD activity,and the intraperitoneal injection had better effect on increasing liver's GSH-PX activity.Intraperitoneal injection had better effect on reducing kidney' s MDA content and increased SOD activity.Two kinds of delivery methods had the same effect on reducing the heart's MDA content.Conclusion The two delivery methods can both make the MDA levels of KK mice in serum,heart,liver and kidney fall to as normal as that of control group,but the two delivery methods have different ways of improving the antioxidant capacity in different organs.Intraperitoneal injection can reduce MDA content in serum and kidney better.
ABSTRACT
Dyslipidemia refers to the elevated cholesterol,triacylglyceride levels and/or the reduced high density lipoprotein level.It is the important risk factor for the occurrence of atherosclerosis,and it is alsoassociated with the onset and outcome of acute cerebrovascular disease.Therefore,the highly efficient and comprehensive lipid lowering therapy has become one of the most important and effective prevention measures for cerebrovascular disease.This article reviews the recent advances in research on dyslipidemia and lipid lowering therapy in patients with cerebrovascular disease.
