ABSTRACT
Objective:To explore the material basis and mechanism of acute stroke treated with Rhei Radix et Rhizoma based on Homotherapy for Heteropathy using the analysis of proteomics and bioinformatics. Method:A total of 60 male Sprague-Dawley（SD）rats were randomly divided into ischemic stroke（IS） sham-operation group (Sham1), IS model group (IS), IS+ Rhei Radix et Rhizoma treatment group (DH1)，ICH sham-operation group (Sham2), intracerebral hemorrhage（ICH） model group (ICH), and ICH + Rhei Radix et Rhizoma treatment group (DH2), with 10 rats in each group. After cerebral perfusion, the brain tissues were quantified by proteomic analysis, and differentially expressed proteins (DEPs) were identified. Specimens of IS, Sham1, and DH1 groups were collected at 24 hours, while those of ICH, Sham2, and DH2 groups were collected at 48 hours. The common DEPs were analyzed by bioinformatics, and the relevant DEPs were verified by Western blot. Result:Rhei Radix et Rhizoma regulated 21 common DEPs associated with acute stroke (including 12 up-regulated and 9 down-regulated). According to Kyoto Encyclopedia of Genes and Genomes（KEGG） analysis, amyotrophic lateral sclerosis (ALS) pathway was enriched, and three proteins [Neurofilament light polypeptide (Nefl), Neurofilament medium polypeptide (Nefm), Neurofilament heavy polypeptide (Nefh)] involved in this pathway. Energy metabolism, ion homeostasis, regulation of synaptophysin, cell cycle and neurogenesis were the common mechanisms of "Homotherapy for Heteropathy". After treatment with Rhei Radix et Rhizoma, the expression levels of GTP binding protein REM2 (Rem2), tyrosine 3-monooxygena (Th), Nefl and neuromodulin (Gap43) were significantly higher than those of the corresponding model group (P<0.05). The expression of Nefl was down-regulated, while the expressions of Rem2，Th and Gap43 were up-regulated, which was consistent with the results of proteomics. Conclusion:Rhei Radix et Rhizoma-homotherapy-differential protein expression profile is established is study. Energy metabolism, ion homeostasis, regulation of synaptophysin, cell cycle and neurogenesis are the common mechanisms.
ABSTRACT
OBJECTIVE@#To evaluate the effect of Buyang Huanwu Decoction (, BYHWD) on glial scar after intracerebral hemorrhage (ICH) and investigate the underlying mechanism.@*METHODS@#Collagenase type VII (0.5 U) was injected stereotaxically into right globus pallidus to induce ICH model. One hundred and twenty Sprague-Dawley rats were randomly divided into 3 groups according to a random number table, including normal group (n=40), ICH model group (n=40) and BYHWD group (n=40), respectively. After ICH, the rats in the BYHWD group were intragastrically administered with BYHWD (4.36 g/kg) once a day for 21 days, while the rats in ICH group were administered with equal volume of distilled water for 21 days, respectively. Double immunolabeling was performed for proliferating cell nuclear antigen (PCNA)/glial fibrillary acidic protein (GFAP) nuclei. The expression of GFAP and leukemia inhibitory factor (LIF) was evaluated by immunohistochemistry and quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR).@*RESULTS@#The astrocytes with hypertrophied morphology around the hematoma was observed on day 3 after ICH. The number of GFAP positive cells and GFAP mRNA levels increased notably on day 3 and reached the peak on day 14 post-ICH (P<0.01). PCNA+/GFAP+ nuclei were observed around the hematoma and reached the peak on day 14 post-ICH (P<0.01). In addition, LIF-positive astrocytes and LIF mRNA level in the hemorrhagic region increased significantly till day 14 post-ICH (P<0.01). However, BYHWD not only reduced the number of PCNA/GFAP nuclei, but also decreased GFAP and LIF levels (P<0.05).@*CONCLUSIONS@#BYHWD could attenuate ICH-induced glial scar by downregulating the expression of LIF in the rats.
ABSTRACT
<p><b>OBJECTIVES</b>To evaluate the effectiveness and safety of Guipi Decoction (, GPD) as an adjunctive in the treatment of depression.</p><p><b>METHODS</b>A review of all relevant studies retrieved from a search of the following databases were conducted without any language restriction: Excerpt Medica Database (EMBASE), PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), VIP Information, Wanfang Data, and the Chinese Biomedical Literature Database. Papers published until February 2013 were taken into consideration. The analysis was performed using the Cochrane software Revman 5.1.</p><p><b>RESULTS</b>Nine randomized controlled trials involving 620 patients with depression were included in this review. The meta-analysis revealed that compared with antidepressant therapy alone, treatment with a combination of GPD and an antidepressant drug signifificantly improved the symptoms of depression [weighted mean difference (WMD):-3.09; 95% confifidence interval (CI):-4.11 to-2.07] and increased the rates of effectiveness (OR: 4.75; 95% CI: 2.66-8.51) as well as recovery (OR: 1.73; 95% CI: 1.17-2.56). The adverse effects of GPD were not found to be signifificant in these studies.</p><p><b>CONCLUSIONS</b>The fifindings of this meta-analysis were in keeping with the notion that GPD formulations were effective in the treatment of depression without causing any serious adverse effects. However, currently available evidence was of low quality and therefore inadequate to justify a strong recommendation of using GPD formulations in the management of depression.</p>
ABSTRACT
Based on the pathophysiology of the brain, advance in angiogenesis induced by stroke, and evidences of Chinese-medicine-mediated angiogenesis, the possibility to study the stroke-treating mechanism of Chinese medicine in angiogenesis was discussed. And regarding our previous work on angiogenesis modulated by qi-tonifying and stasis-eliminating therapy following intracerebral hemorrhage, we proposed some questions, which should be taken into account in the further work.
