Rat models were intragastrically administered 5, 10, 20 g/kg Poxue Huayu and Tianjing Busui Decoction, supplemented with Hirudo, raw rhubarb, raw Pollen Typhae, gadfly, Fructrs Trichosanthis, Radix Notoginseng, Rhizoma Acori Talarinowii, and glue of tortoise plastron, once a day, for 14 consecutive days. Results demonstrated that brain water content significantly reduced in rats with cerebral hemorrhage, and intracerebral hematoma volume markedly reduced after treat- ment. Immunohistochemical staining revealed that brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor expression noticeably increased around the sur- rounding hematoma. Reverse transcription-PCR revealed that brain-derived neurotrophic factor and tyrosine kinase B mRNA expression significantly increased around the surrounding hematoma. Neurologic impairment obviously reduced. These results indicated that Poxue Huayu and Tianjing Busui Decoction exert therapeutic effects on cerebral hemorrhage by upregulating the expression of brain-derived neurotrophic factor.展开更多

Gerbils were pretreated with BYHWD, and then subjected to cerebral ischemia and reperfusion. Microvascular changes were determined with laser Doppler monitoring, tannic acid-ferric chloride mordant, and electron microscopy. Results showed that BYHWD pretreatment could enhance the function of hippocampal microvessels, prevent injury, and increase microvasular density and microvasular area density. Thus, these results suggest that BYHWD pretreatment could prevent microvascular occlusion, enhance the capacity of microvascular reperfusion, increase cerebral blood flow, and inhibit neuronal damage, and may be an effective therapy against brain ischemic injury.展开更多

Methods： Sixty patients with ACH were equally randomized into two groups by lottery, the control group and the THG group; all were treated with conventional therapy, but to the patients in the THG group, THG was given orally in addition for 28 days. Changes of ICP, MMP-9 expression, and NIHSS scores, as well as the degree of cerebral hematoma and hydrocephalus （by cranial CT scanning） in the patients, were estimated and compared. Results： （1） ICP was lowered more significantly in the THG group, showing a significant difference between groups on day 7 （P〈0.05）. （2） MMP-9 expression was down-regulated in the THG group more significantly and earlier than that in the control group. （3） The degrees of cerebral hematoma and hydrocephalus in the THG group on day 7 were reduced significantly as compared with those on day 3 （P〈0.05）, but in the control group, the day of significant reduction was delayed to day 14, and the degrees on day 7 and day 14 in the two groups were significantly different （P〈0.05 and P〈0.01）. （4） NIHSS score was significantly lower in the THG group than that in the control group on day 14 and day 28 （P〈0.05 and P〈0.01）. Conclusion： THG can effectively lower ICP, down-regulate MMP-9 expression, promote the absorption of cerebral hematoma and hydrocephalus, and improve the nerve function, showing a clinical effectiveness than conventional therapy.展开更多

Vascular endothelial growth factor （VEGF） has been considered a potential therapeutic target for stroke. Buyang Huanwu decoction （BYHWD） is a classic traditional formula in traditional Chinese medicine and is used to treat stroke; in addition, the promotion effects on VEGF protein expression have been confirmed. However, little is known about how BYHWD regulates angiogenesis, or about the effects of BYHWD on VEGF mRNA expression. For this reason, the present study measured microvessel density in rats with cerebral ischemia using immunohistochemistry. In addition, VEGF expression was measured by re-verse-transcription polymerase chain reaction and enzyme-linked immunosorbent assay to determine the effects of BYHWD on angiogenesis and VEGF expression in rats with cerebral ischemia. Results demonstrated that microvessel density, as well as VEGF mRNA and protein expression, increased after 7 and 14 days of BYHWD treatment, which suggests that BYHWD promoted angiogenesis following cerebral ischemia and upregulated VEGF mRNA and protein expression in ischemic cerebral regions.展开更多

There is no standard treatment for hemorrhagic CRP. Medical treatment, interventional treatment, and surgery are available, but they are limited in their applications due to nondefinite efficacy or side effects. Chinese herbal medicine(CHM), as a complementary or alternative therapy, may provide another option for hemorrhagic CRP treatment.CASE SUMMARY A 51-year-old woman with cervical cancer received intensity-modulated radiation therapy and brachytherapy with a total dose of 93 Gy fifteen days after hysterectomy and bilateral adnexectomy. She received six additional cycles of chemotherapy with carboplatin and paclitaxel. Nine months after radiotherapy treatment, she mainly complained of 5-6 times diarrhea daily and bloody purulent stools for over 10 d. After colonoscopy examinations, she was diagnosed with hemorrhagic CRP with a giant ulcer. After assessment, she received CHM treatment. The specific regimen was 150 mL of modified Gegen Qinlian decoction(GQD) used as a retention enema for 1 mo, followed by replacement with oral administration of 150 mL of modified GQD three times per day for 5 mo. After the whole treatment, her diarrhea reduced to 1-2 times a day. Her rectal tenesmus and mild pain in lower abdomen disappeared. Both colonoscopy and magnetic resonance imaging confirmed its significant improvement. During treatment,there were no side effects, such as liver and renal function damage.CONCLUSION Modified GQD may be another effective and safe option for hemorrhagic CRP patients with giant ulcers.展开更多

I...The traditional Chinese medicine Buyang Huanwu Decoction has been shown to improve the neu- rological function of patients with stroke. However, the precise mechanisms underlying its effect remain poorly understood. In this study, we established a rat model of cerebral ischemia by middle cerebral artery occlusion and intragastrically administered 5 g/kg Buyang Huanwu Decoction, once per day, for 1, 7, 14 and 28 days after cerebral ischemia. Immunohistochemical staining revealed a number of cells positive for the neural stem cell marker nestin in the cerebral cortex, the subven- tricular zone and the ipsilateral hippocampal dentate gyrus in rat models of cerebral ischemia. Buyang Huanwu Decoction significantly increased the number of cells positive for 5-bromodeoxyuridine （BrdU）, a cell proliferation-related marker, microtubule-associated protein-2, a marker of neuronal differentiation, and growth-associated protein 43, a marker of synaptic plasticity in the ischemic rat cerebral regions. The number of positive cells peaked at 14 and 28 days after intragastric administration of Buyang Huanwu Decoction. These findings suggest that Buyang Huanwu Decoction can promote the proliferation and differentiation of neural stem cells and en- hance synaptic plasticity in ischemic rat brain tissue.展开更多

文摘Objective To identify whether Banxia Xiexin Decoction(BXD)alleviates cerebral glucose metabolism disorder by intestinal microbiota regulation in APP/PS1 mice.Methods Forty-five 3-month-old male APP/PS1 mice were divided into 3 groups using a random number table(n=15 per group),including a model group(MG),a liraglutide group(LG)and a BXD group(BG).Fifteen 3-month-old male C57BL/6J wild-type mice were used as the control group(CG).Mice in the BG were administered BXD granules by gavage at a dose of 6 g/(kg·d)for 3 months,while mice in the LG were injected intraperitoneally once daily with Liraglutide Injection(25 nmol/kg)for 3 months.Firstly,liquid chromatography with tandem-mass spectrometry was used to analyze the active components of BXD granules and the medicated serum of BXD.Then,the cognitive deficits,Aβpathological change and synaptic plasticity markers,including synaptophysin(SYP)and postsynaptic density protein 95(PSD95),were measured in APP/PS1 mice.Brain glucose uptake was detected by micropositron emission tomography.Intestinal microbial constituents were detected by 16S rRNA sequencing.The levels of intestinal glucagon-like peptide 1(GLP-1)and cerebral GLP-1 receptor(GLP-1R),as well as the phosphoinositide-3-kinase/protein kinase B/glycogen synthase kinase-3β(PI3K/Akt/GSK3β)insulin signaling pathway were determined by immunohistochemical(IHC)staining and Western blot analysis,respectively.Results BXD ameliorated cognitive deficits and Aβpathological features(P<0.01).The expressions of SYP and PSD95 in the BG were higher than those in the MG(P<0.01).Brain glucose uptake in the BG was higher than that in the MG(P<0.01).The intestinal microbial composition in the BG was partially reversed.The levels of intestinal GLP-1 in the BG were higher than those in the MG(P<0.01).Compared with the MG,the expression levels of hippocampal GLP-1R,Akt,PI3K and p-PI3K in the BG were significantly increased(P<0.01),while the levels of GSK3βwere reduced(P<0.01).Conclusion BXD exhibited protective effects against Alzheimer’s disease by regulating the gut microbiota/GLP-1/GLP-1R,enhancing PI3K/Akt/GSK3βinsulin signaling pathway,and improving brain glucose metabolism.
