Anti-depression-like effect of Mogroside V is related to the inhibition of inflammatory and oxidative stress pathways.

Siraitia grosvenorii (SG) is an edible medicinal plant found mainly in Guangxi, China, and Mogroside V (MGV) is the main component of SG extract. Previous research has shown that SG and MGV exert anti-inflammatory, antioxidative and neuroprotective effects. However, it is not clear whether MGV has anti-depression-like effect. In this study, we evaluated the neuroprotective effects and anti-depression-like effect of MGV both in vitro and in vivo. By performing in vitro tests, we evaluated the protective effects of MGV on PC12 cells with corticosterone-induced injury. In vivo tests, we used the chronic unpredictable mild stress (CUMS) depression model. Fluoxetine (10 mg/kg/day) and MGV (10 or 30 mg/kg/day) were administered by gavage for 21 days, and the open field test (OFT), novelty suppressed feeding test (NSFT), Tail suspension test (TST), and forced Swimming test (FST) were used to evaluate the depressive-like behaviors. In addition, we investigated the role of proinflammatory cytokines (IL-1ß, IL-6, and TNF-α) and anti-inflammatory cytokine (IL-4) in the hippocampal and cortex tissues. The levels of Superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-PX) in hippocampal and cortex tissues were also measured. Pathological changes in the hippocampal dentate gyrus and cortex regions were detected by immunofluorescence and Western blotting was used to measure the protein expression of BDNF, TrkB, TNF-α, and AKT. The results showed that MGV had a protective effect on PC12 cells with corticosterone-induced incurred injury. In addition, MGV treatment relieved the depressive symptoms and significantly reduced inflammatory levels (IL-1ß, IL-6, and TNF-α). MGV also significantly reduced oxidative stress damage and reduced the levels of apoptosis in hippocampal nerve cells. These results suggested that the anti-depressive effect of MGV may occur through the inhibition of inflammatory and oxidative stress pathways and the BDNF/TrkB/AKT pathway. These findings provide a new concept for the identification of new anti-depressive strategies.

Sophora alopecuroides Alleviates Neuroinflammation and Oxidative Damage of Parkinson's Disease In Vitro and In Vivo.

For centuries, Sophora alopecuroides L. has been used both as a food and an herbal medicine in northern China. A new cytisine-type alkaloid, N-methylene-(5,7,4[Formula: see text]-trihydroxy)-isoflavone (LY01), was found in the fruits of Sophora alopecuroides L. and shows neuroprotective effects against Parkinson's disease (PD). PD is a frequently occurring, irreversible neurodegenerative disease that seriously threatens the health of the elderly population. There is no cure for PD. The available treatments help manage the symptoms, but their use is limited by multiple side effects. Therefore, more pharmacological treatments addressing this pathology are urgently required. This study aimed to evaluate the neuroprotective effects of LY01 against PD, as well as their underlying mechanisms, using both in vitro and in vivo experimental models. A 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine hydrochloride (MPTP)-induced mouse model of PD was used to assess the effects of LY01 on the motor coordination deficit, progression of the pathology, and molecular characteristics. 1-Methyl-4-phenylpyridinium (MPP[Formula: see text])-activated SH-SY5Y cells and lipopolysaccharide (LPS)-activated BV-2 cells were used to evaluate LY01 effects on oxidative damage and neuroinflammation. In the rotarod test, LY01 alleviated the impaired motor coordination in PD mice. Furthermore, LY01 treatment prevented the loss of dopaminergic neurons in the substantia nigra and striatum of the PD mice, reduced neuroinflammation in the mice with MPTP-induced PD and the LPS-activated BV-2 cells, and diminished oxidative stress in the PD mice and the MPP[Formula: see text]-induced SH-SY5Y cells. In conclusion, these results suggest the potential of LY01 as a therapeutic agent for treating PD.

Mechanism of Neural Regeneration Induced by Natural Product LY01 in the 5×FAD Mouse Model of Alzheimer's Disease.

Background: A sharp decline in neural regeneration in patients with Alzheimer's disease (AD) exacerbates the decline of cognition and memory. It is of great significance to screen for innovative drugs that promote endogenous neural regeneration. Cytisine N-methylene-(5,7,4'-trihydroxy)-isoflavone (LY01) is a new compound isolated from the Chinese herbal medicine Sophora alopecuroides with both isoflavone and alkaloid characteristic structures. Its pharmacological effects are worth studying. Objective: This study was designed to determine whether LY01 delays the cognitive and memory decline in the early stage of AD and whether this effect of LY01 is related to promoting neural regeneration. Methods: Eight-week-old 5×Familial Alzheimer's Disease (5×FAD) mice were used as disease models of early AD. Three doses of LY01 administered in two courses (2 and 5 weeks) of treatment were tested. Cognition, memory, and anxiety-like behaviors in mice were evaluated by the Morris water maze, fear conditioning, and open field experiments. Regeneration of neurons in the mouse hippocampus was observed using immunofluorescence staining. The effect of LY01 on cell regeneration was also demonstrated using a series of tests on primary cultured neurons, astrocytes, and neural stem cells (NSCs). In addition, flow cytometry and transcriptome sequencing were carried out to preliminarily explored the mechanisms. Results: We found that LY01 reduced the decline of cognition and memory in the early stage of 5×FAD mice. This effect was related to the proliferation of astrocytes, the proliferation and migration of NSCs, and increases in the number of new cells and neural precursor cells in the dentate gyrus area of 5×FAD mice. This phenomenon could be observed both in 2-week-old female and 5-week-old male LY01-treated 5×FAD mice. The neuronal regeneration induced by LY01 was related to the regulation of the extracellular matrix and associated receptors, and effects on the S phase of the cell cycle. Conclusion: LY01 increases the proliferation of NSCs and astrocytes and the number of neural precursor cells in the hippocampus, resulting in neural regeneration in 5×FAD mice by acting on the extracellular matrix and associated receptors and regulating the S phase of the cell cycle. This provides a new idea for the early intervention and treatment of AD.

Sanweidoukou decoction, a Chinese herbal formula, ameliorates ß-amyloid protein-induced neuronal insult via modulating MAPK/NF-κB signaling pathways: Studies in vivo and in vitro.

ETHNOPHARMACOLOGICAL RELEVANCE: The traditional Chinese medicine Sanweidoukou decoction (DK-3) was a classical formula for the treatment of nervous system diseases, recorded in the Chinese medical classic Sibu Yidian. AIM OF THE STUDY: The present study is aim to investigate the neuroprotective effects of DK-3 on ß-amyloid (Aß) protein -induced AD-like pathologies and underlying molecular mechanisms both in vitro and in vivo studies. MATERIALS AND METHODS: Hydrolysates of DK-3 were analyzed by LC-ESI-MS/MS. In vitro, MTT was utilized to examine effects of DK-3 on Aß25-35-induced cytotoxicity in PC12 cells. In vivo, male Sprague-Dawley rats were administered with Aß25-35 to induce AD-like pathologies and behavioral evaluations were conducted via Morris water maze (MWM) test. Histopathological changes were observed by Hematoxylin-eosin (HE) straining. Immunohistochemistry (IHC) was used to detect the tau hyperphosphorylation at Thr181 site. The expression levels of tau hyperphosphorylation, inflammation-related cytokines such as COX-2, iNOS, TNF-α, IL-1ß, IL-6, the phosphorylated state of various mitogen-activated protein kinase (MAPK) signaling molecules (p38 MAPK, ERK, and JNK) and activation of nuclear factor κB (NF-κB) in vitro and in vivo were assessed via Western blot. RESULTS: In vitro, DK-3 dose-dependently increased cell viability of PC12 cells induced by Aß25-35. In vivo, DK-3 improved learning and memory abilities of Aß25-35-induced AD-like rats. Moreover, DK-3 reversed hyperphosphorylation of tau and reduced the production of inflammation-related cytokines through significantly inhibited MAPK and NF-κB signaling pathways both in vitro and in vivo studies. CONCLUSION: The present study suggested that the traditional Chinese medicine DK-3 may play a role in preventing and treating AD by reducing the hyperphosphorylation of tau protein and the expressions of inflammation-related cytokines via modulating the MAPK/NF-κB signaling pathways.

Traditional Chinese Medicine Decoction Combined With Antipsychotic for Chronic Schizophrenia Treatment: A Systematic Review and Meta-analysis.

Despite several studies suggesting the effectiveness of traditional Chinese medicine (TCM) in schizophrenia, there is still a lack of systematic summary and analysis on the role of TCM as adjuvant therapy in chronic schizophrenia. For this purpose, we conducted a meta-analysis to study the efficacy of TCM as an adjuvant combined with antipsychotics in the treatment of chronic schizophrenia. Until April 2020, based on the review of six electronic databases, eight articles were selected. The articles compared TCM decoction assisted antipsychotic therapies with an antipsychotic alone in the treatment of chronic schizophrenia by analyzing a total of 810 cases. The results showed that TCM combined with antipsychotics have beneficial effects on the Positive and Negative Syndrome Scale (PANSS), including the changes in total score, negative score, and the clinical effects evaluated by the PANSS scale. Subgroup analysis showed that the effects of auxiliary TCM with different efficacy on the positive and psychopathological scores were significantly different. It was found that adjuvant treatment with TCM can reduce some side effects and improve the patient's living conditions in the evaluation of the Schizophrenia Quality Of Life Scale (SQLS). Many studies have proved that TCM is safe and well-tolerated. Although the difficulties of using limited TCM remains to be generalized, it still has great potential in the adjuvant treatment of chronic schizophrenia.

Mallotus oblongifolius extracts ameliorate ischemic nerve damage by increasing endogenous neural stem cell proliferation through the Wnt/ß-catenin signaling pathway.

Mallotus oblongifolius (MO), an edible medicinal plant from Hainan in China, shows a wide range of bioactivities. The daily consumption of MO or its extracts has been observed to ameliorate ischemic nerve injury. However the mechanisms remain unclear. In this study, the effects of MO both in vitro and in vivo were investigated. The results indicated that MO improved the motor ability, neurosensory ability, balance and grasping ability of mice with ischemic injuries, induced by bilateral common carotid artery ligation (BCCAL). In addition, MO improved the morphology of neurons, resisted the loss of neurons, and enhanced the content of the nestin protein in the cerebral cortex and subgranular zone (SGZ) area. Furthermore, in the oxygen-glucose deprivation and reperfusion (OGD/R) treated cell model, MO could effectively activate the Wnt/ß-catenin signaling pathway and promote the proliferation of neural stem cells (NSCs) and increase the protein expression levels of ß-catenin and CyclinD1. Our results suggest that Mallotus oblongifolius may be used as nutraceuticals or functional foods to alleviate ischemic nerve damage and promote recovery from ischemic stroke.

2,3,5,4'-Tetrahydroxystilbene-2-O-ß-d-glucoside attenuates MPP+/MPTP-induced neurotoxicity in vitro and in vivo by restoring the BDNF-TrkB and FGF2-Akt signaling axis and inhibition of apoptosis.

The major bioactive ingredient THSG of Polygonum multiflorum is well established for its anti-oxidation, anti-aging and anti-inflammation properties. Increasing evidence supports the capacity of THSG to ameliorate the biochemistry of neurotrophins and their downstream signaling axis in mouse models to attenuate neurodegenerative diseases such as Alzheimer's and Parkinson's disease. In this study, the neuroprotective effects of THSG were studied in vitro and in vivo. In cultured mesencephalic dopamine neurons and SH-SY5Y cell line, it was found that THSG protected the integrity of the cell body and neurite branching from MPP+-induced toxicity by restoring the expression of FGF2 and BDNF and their downstream signaling pathways to inhibit apoptosis and promote cell survival. The inhibition of Akt signaling by LY294002 or TrkB activity by K252a eliminated the neuroprotective effects of THSG. In the MPTP-induced mouse models of Parkinson's disease, THSG ameliorated the animal behaviors against MPTP-induced neurotoxicity, which was demonstrated by the pole test and the tail suspension test. Biochemical and immunohistochemical analysis verified the THSG-mediated restoration of the FGF2-Akt and BDNF-TrkB signaling axis in the substantia nigra and corpus striatum and the recovery of dopaminergic neurons. These results establish the neuroprotective effects of THSG in vitro and in vivo and unravel the underlying mechanism against toxin-induced neural atrophy, providing a new avenue for the use and pharmacological research of edible medicine for anti-neurodegenerative diseases.

Total flavonoid extract from Dracoephalum moldavica L. attenuates ß-amyloid-induced toxicity through anti-amyloidogenesic and neurotrophic pathways.

AIMS: Alzheimer's disease (AD) is an incurable neurodegenerative disorder characterized by global cognitive impairment that involves accumulation of amyloid-beta peptides (Aß) in the brain. Herbal approaches can be used as alternative medicines to slow the progression of AD. This study aimed to determine the beneficial effects and potential underlying mechanisms of total flavonoid extract from Dracoephalum moldavica L. (TFDM) for attenuating Alzheimer-related deficits induced by Aß. MAIN METHODS: We used amyloid precursor protein (APP) and presenilin 1 (PS1) double transgenic mice and copper-injured APP Swedish mutation overexpressing SH-SY5Y cells to evaluate the beneficial effects of TFDM. Further, identifying the mechanisms of action was conducted on anti-amyloidogenic and neurotrophic transductions. KEY FINDINGS: Our results indicated that TFDM treatment ameliorated cognitive impairments and neurodegeneration and improved the antioxidant defense system in APP/PS1 mice. TFDM also reduced Aß burden by relieving Aß deposition, decreasing insoluble Aß levels, and inhibiting ß-amyloidogenic processing pathway involving downregulation of ß-secretase and ß-C-terminal fragment in the brain. In the in vitro model of AD, TFDM treatment protected injured cells, and combined with the beneficial effects of decreasing APP levels, lowered Aß1-42 and regulated the redox imbalance. Moreover, TFDM preserved the extracellular signal-regulated kinase/cAMP response element-binding protein/brain-derived neurotrophic factor pathway both in vitro and in vivo. SIGNIFICANCE: In conclusion, TFDM clearly demonstrated neuroprotective effects by restoring the anti-amyloidogenic and neurotrophic transductions in the context of AD-associated deficits. These findings indicate the potential use of herb-based substances as supplements or potential alternative supplements for attenuating the progression of AD.

Neuroprotective effects of a Coeloglossum viride var. Bracteatum extract in vitro and in vivo.

The excessive release and accumulation of glutamate in the brain is known to be associated with excitotoxicity. CE, an extract derived from the plant Coeloglossum viride var. Bracteatum, exerted neuroprotective effects against amyloid toxicity and oxidative stress in cortical neurons. The aims of this study are to examine whether CE also attenuates glutamate neurotoxicity in rat primary cultured cortical neurons and to determine the effect of CE in vivo. According to the results of MTT, LDH release, and TUNEL assays, the CE treatment significantly reduced glutamate-induced neurotoxicity in a dose-dependent manner. Moreover, the protective effects of CE were blocked by an Akt inhibitor, LY294002, suggesting that the PI3K/Akt signalling pathway is involved in the neuroprotective effects of CE. In addition, CE might regulate the PKC-GluA2 axis to prevent neuronal apoptosis. CE also protected against dopaminergic neuronal loss in a mouse model of MPTP-induced PD. Based on our results, CE exerted neuroprotective effects both in vitro and in vivo, thus providing a potential therapeutic target for the treatment or prevention of neurodegeneration.

Low dose of caffeine enhances the efficacy of antidepressants in major depressive disorder and the underlying neural substrates.

SCOPE: Caffeine is one of the most frequently used psychoactive substances ingested mainly via beverage or food products. Major depressive disorder is a serious and devastating psychiatric disorder. Emerging evidence indicates that caffeine enhances the antidepressant-like activity of common antidepressant drugs in rodents. However, whether joint administration of low dose of caffeine enhances the antidepressant actions in depressed patients remains unclear. METHODS AND RESULTS: A total of 95 male inpatients were assigned to three groups and were asked to take either caffeine (60, 120 mg) or placebo (soymilk powder) daily for 4 wk on the basis of their current antidepressant medications. Results showed that chronic supplementation with low dose of caffeine (60 mg) produced rapid antidepressant action by reduction of depressive scores. Furthermore, low dose of caffeine improved cognitive performance in depressed patients. However, caffeine did not affect sleep as measured by overnight polysomnography. Moreover, chronic caffeine consumption elicited inhibition of hypothalamic-pituitary-adrenal axis activation by normalization of salivary cortisol induced by Trier social stress test. CONCLUSIONS: These findings indicated the potential benefits of further implications of supplementary administration of caffeine to reverse the development of depression and enhance the outcome of antidepressants treatment in major depressive disorder.

[Neuro-protective effects and mechanism of Terminalia chebula extract HZ4 on cerebral infarction models].

To study the effect and possible molecular mechanisms of Terminalia chebula extract HZ4 on focal cerebral infarction in rats, 90 healthy male SD rats were randomly divided into sham-operation group, model group, T. chebula extract HZ4 high dose, middle dose and low dose groups (80, 40, 20 mg•kg ⁻¹â€¢d ⁻¹, ig) and positive control group (Panax notoginseng saponins, PNS 30 mg•kg ⁻¹â€¢d ⁻¹, ig). The focal cerebral infarction models were established by photochemical method. After the rats were administered for 7 consecutive days, neurogenic behavior rating of these rats was done by balance beam test and foot fault test. The cells morphological changes of penumbra in focal cerebral infarction were investigated by HE staining method; the infarct volume was detected by TTC staining. The expression levels of ß-catenin and cyclin D1, the key node genes in Wnt signaling pathway of the focal penumbra tissues were detected via RT-PCR. The results showed that, as compared with the model group, behavioural indicators were improved significantly in the rats of administration groups, and the infarct volume and pathological changes of penumbra tissues were also improved at the same time. Compared with the model group, the expression levels of ß-catenin and cyclin D1 in Wnt signaling pathway were significantly up-regulated in administration groups(P<0.01). This study first confirmed that T. chebula extract HZ4 can decrease infarct volume, improve the sport ability score, and promote rehabilitation of model animals. In addition, it could significant up-regulated the expression levels of ß-catenin and cyclin D1, and the mechanism may be associated with Wnt signaling pathway. The study is innovative to a certain extent.

[Analysis on signaling pathway network of proliferation of neural stem cells].

Neural stem cells in brains have capacities of proliferation and differentiation, which is very critical to rebuild the cerebral cortex functions. Therefore, it is of great importance to find key targets and network pathways that regulate the proliferation of neural stem cells, which is also a pressing problem in the medical circle. With the Notch pathway as the core of the network, this paper summarized the advance of the bimolecular network system composed of Wnt, Shh, EGFR, cytokines and Notch signal, and analyzed such key nodes as Notch receptor, CBF1, NICD, Hesl, which may become potential targets of new-type drugs in the future. With the multi-component, multi-target, multi-lever characteristics, traditional Chinese medicines have many common grounds with the network pharmacology. The active component groups or active ingredients in traditional Chinese medicines are one of the material bases for showing their network pharmacological effect, which is worth exploring. This paper aims to provide a new strategy for the treatment of neurodegenerative disease and nerve injury with traditional Chinese medicines.

[Study on directional separation of picroside II from extract of traditional Chinese medicine by molecularly imprinted technology].

Picroside II, separated from Chinese herbal medicine, is an active compound with neroprotective activity. Molecularly imprinted polymers (MIPs) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcomings of traditional separation methods, such as complex operation and low efficiency. In this paper, MIPs were prepared by precipitation polymerization with picroside II as the template molecule, 1-vinylimidazole (1-Vinyl) as functional monomer, ethylene glycol dimethacrylate (EDMA) as cross-linker. The morphology of MIPs was characterized by scanning electronmicroscope (SEM) and its static adsorption capacity was measured by the scatchard equation. The results showed that picroside II MIPs have spherical shape, and most of them are uniform in size. Furthermore, the maximum binding capacity (Q(max)) of MIPs is 3.02 mg x g(-1), higher than that of non-imprinted polymers (NIPs). This result indicated that picroside II MIPs with good morphology and high targeted affinity toward the template molecules can be prepared by precipitation polymerization, which can be used to separate picroside II and its analogies from extract of Chinese herbal medicine. In addition, this method has the advantages of good environment and simple operation, which might offer a novel method for the efficient separation of picroside II in the traditional herbal medicines.

[Research on effect of Baimai powder effective compounds group promotes neurogenesis and maintains of neural stem cells after cerebral infarction].

The neural stem cells (NSCs), play a crucial role in stroke treatment, which can be regulated by a few of traditional Chinese medicines. In this study, the effect of the Mongolian medicine Baimai powder effective compounds group (BMECG) on the proliferation of NSCs has been investigated. The cultured NSCs which were isolated from newborn rat cerebral cortical in vitro were exposed to oxygen glucose deprivation/reoxgenation (OGD/R). The CFSE immunofluorescence staining was employed to identify the proliferation of NSCs by flow cytometry. Furthermore, the bilateral carotid artery occlusion (BCAO) was established on Kunming mice, and all groups were ig for 7 d respectively. The neurobehavioral changes was studied with rota-rod treadmill test, after that, the brain of mice were detected by immunohistochemistry with labeling of Nestin and pathological observation at 7 days after BCAO. It was found that, proliferation of NSCs was increased by BMECG in in vitro and in vivo. And BMECG significantly improved the time of staying in the rota-rod, it can promote the foundction of in cerebral cortex. It is concluded that these results further support the hypothesis that neuroprotective effect of BMECG may relate to the ability of stimulating self-renew of NSCs, which can be provided a new insight and strategy of anti-neuropathy of stroke.

The results showed that ginsenoside Rg1 MIPs prepared by the above two methods had a high adsorption performance to template molecules, with the maximum apparent adsorbing capacity of up to 27.74, 46. 80 mg x g(-1), respectively. Moreover, MIPs prepared by surface imprinted polymerization showed higher adsorption capacity than that by precipitation polymerization. The experimental results indicated that as for ginsenoside Rg1 with higher polarity, MIPs prepared by surface imprinted polymerization showed higher selectivity and adsorption performance, which provides provide important reference for preparing imprinted polymers with good adsorption performance with active molecules with strong polarity.

Effective compounds group of Mongolian prescriptions BAIMAI-SAN protect against peripheral neuropathy in lower limbs of rats through neuro protective effect.

ETHNOPHARMACOLOGICAL RELEVANCE: BAIMAI-SAN prescription is a famous Chinese minority complex prescription used for curing neuropathy. MATERIALS AND METHODS: The Effective Compounds Groups of BAIMAI-SAN (ECGBM) is determined by high through-put screening, and it includes picroside II, verbascose, taurine and ellagic acid and borneol. To research the potential protective effect of ECGBM on the function of peripheral neuropathy, diabetic rats with peripheral neuropathy were induced by streptozotocin and treated with ECGBM (0.1, 0.3, 0.9 mg/kg/day i.g.) for 75 days. Primary cortical neuronal cultures were subjected to high d-glucitol, and treated with ECGBM prophylactically. RESULTS: The administration resulted in reductions in speed of sciatic motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV) and response speed to pain in the sciatic nerve fiber. Data from primary cortical neuronal cultures experiments indicated that neuronal survival rates were increased, and LDH release was decreased and the loss of neurite length was alleviated in ECGBM group. CONCLUSIONS: It is first report that ECGBM could protect the peripheral neuron in diabetic rat in vivo and in vitro. This activity may be associated with the neuron protective effect.
