Upregulation of NADPH-oxidase, inducible nitric oxide synthase and apoptosis in the hippocampus following impaired insulin signaling in the rats: Development of sporadic Alzheimer's disease. Brain Res 2024; 1834:148890. [PMID: 38552936 DOI: 10.1016/j.brainres.2024.148890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 02/21/2024] [Accepted: 03/26/2024] [Indexed: 04/06/2024]
Abstract
NADPH-oxidase (NOX) is a multi-subunit enzyme complex. The upregulation of NOX causes massive production of superoxide (O2¯), which avidly reacts with nitric oxide (NO) and increases cellular reactive oxygen/nitrogen species (ROS/RNS). Increased ROS/RNS plays pivotal role in the sporadic Alzheimer's disease (sAD) development and brain damage following impaired insulin signaling. Hence, this study aimed to examine early-time course of changes in NOX and NOS expression, and apoptotic proteins in the rats hippocampi following insulin signaling impairment [induced by STZ injection; intraperitoneal (IP) or in cerebral ventricles (ICV)]. Early effects (1, 3, or 6 weeks) on the NOX activity, translocation of NOX subunits from cytosol to the membrane, NO-synthases [neuronal-, inducible- and endothelial-NOS; nNOS, iNOS and eNOS], The Rac-1 protein expression, levels of NO and O2¯, cytochrome c release, caspase-3 and 9 activations (cleavage) were studied. STZ injection (in both models) increased NOX activity, O2¯ production, and enhanced cytosolic subunits translocation into membrane. The iNOS but not nNOS and eNOS expression and NO levels were increased in STZ treated rats. Finally, STZ injection increased cytochrome c release, caspase-3 and 9 activations in a manner that was significantly associated with levels of O2¯ and NO in the hippocampus. ICV-STZ administration resulted in significant profound changes over the IP route. In conclusion, impairment in insulin function induces early changes in ROS/RNS contents through NOX and iNOS upregulation and neuronal apoptosis in the hippocampus. Our results could mechanistically explain the role of impaired insulin function in the development of sAD.

Abstract
Neurogenesis in the adult brain comprises the entire set of events of neuronal development. It begins with the division of precursor cells to form a mature, integrated, and functioning neuronal network. Adult neurogenesis is believed to play an important role in animals' cognitive abilities, including learning and memory. In the present study, significant neuronal differentiation-promoting activity of 80% (v/v) ethanol extract of P. cocos (EEPC) was found in Neuro-2a cells and mouse cortical neural stem/progenitor cells (NSPCs). Subsequently, a total of 97 compounds in EEPC were identified by UHPLC-Q-Exactive-MS/MS. Among them, four major compounds-Adenosine; Choline; Ethyl palmitoleate; and L-(-)-arabinitol-were further studied for their neuronal differentiation-promoting activity. Of which, choline has the most significant neuronal differentiation-promoting activity, indicating that choline, as the main bioactive compound in P. cocos, may have a positive effect on learning and memory functions. Compared with similar research literature, this is the first time that the neuronal differentiation-promoting effects of P. cocos extract have been studied.

Abstract
Skeletal muscle atrophy is the consequence of protein degradation exceeding protein synthesis because of disease, aging, and physical inactivity. Patients with skeletal muscle atrophy have decreased muscle mass and fiber cross-sectional area, and experience reduced survival quality and motor function. The forkhead box O (FOXO) signaling pathway plays an important role in the pathogenesis of skeletal muscle atrophy by regulating E3 ubiquitin ligases and some autophagy factors. However, the mechanism of FOXO signaling pathway leading to skeletal muscle atrophy is still unclear. The development of treatment strategies for skeletal muscle atrophy has been a thorny clinical problem. FOXO-targeted therapy to treat skeletal muscle atrophy is a promising approach, and an increasing number of relevant studies have been reported. This article reviews the mechanism and therapeutic targets of the FOXO signaling pathway mediating skeletal muscle atrophy, and provides ideas for the clinical treatment of this condition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE LiuweiDihuang (LW) pills was mainly used to treatment of children's fontanelle incomplete closure, enuresis and nervous system development delays and other diseases.Following the deepening of pharmacological research, LW has a good effect on neurological diseases include senile dementia. However, the neuroprotection mechanism of LW on Alzheimer's disease (AD) through regulation of inflammation remains unclear. AIM OF THE STUDY Here, we aimed to explore the effects and mechanism of LW on learning and memory deficits in SAMP8 mice. MATERIALS AND METHODS Mice aged 6 months were treated with LW for 2 months and BV2, C6 and HT22 cells were treated with LW pharmaceutic serum and Lipopolysaccharide (LPS) continuously. Then, cognitive tests were performed, including the Morris water maze and Y maze tests. The mRNA level of cyclooxygenase 2 (COX-2) and pro-inflammatory factors (IL-1β, IL-6 and TNF-α) were examined in cells and the cortex and hippocampus by quantitative RT-PCR. The expression of postsynaptic density protein 95, synaptophysin and various inflammatory factors were detected in the cortex and hippocampus by Western blot. Furthermore, Ionized calcium binding adapter molecule 1, glial fibrillary acidic protein and Aβ were examined in the brain of AD mice by immunofluorescence staining and immunohistochemistry. And synaptic loss and neuronal ultrastructure were observed by transmission electron microscope. RESULTS We found that LW suppressed LPS-induced COX-2 expression in vitro. Importantly, LW dramatically improved spatial learning and memory in SAMP8 mice through inhibiting Aβ accumulation and restoring structural synaptic integrity. Furthermore, LW inhibited the glial activation and neuroinflammation (COX-2, IL-1β, IL-6 and TNF-α) in the cortex and hippocampus of SAMP8 mice. CONCLUSION Taken together, the present data not only indicated that LW is an effective agent on improving the learning and memory deficits through mitigating neuroinflammation but highlighted the LW can be a potential therapeutic drug for AD therapy.

Abstract
Long term Diabetes mellitus results in neuronal damage by increased intracellular glucose leading to oxidative stress. This condition is known as diabetic encephalopathy. Morin is a bioflavonoid, has significant antidiabetic, antioxidant and anti-inflammatory activities. The present study investigated whether the antioxidant properties of morin has beneficial effects on structural brain damage, neuronal apoptosis and dysregulation of TrkB/Akt signalling associated with diabetes. Adult male Sprague Dawley rats were induced diabetes by an intraperitoneal injection of 40mg/kg of streptozotocin and kept untreated for 30 days to induce DE. Cognitive performance was assessed using the Morris water maze test followed by morin and metformin administration at the doses of 50 and 100mg/kg, respectively, for 60 days. After 60 days of treatment, animals were subjected to the behavioural test and sacrificed to collect blood and brain and checked biochemical parameters.The treatment with Morin could significantly reduce the escape latency time in Morris water maze test, blood glucose level, HbA1C, toxicity markers, lipid peroxidation products and protein carbonyl content, downregulated the expression of Bax, Caspase 3 and Cytochrome C and upregulated Bcl-2, Bcl-XL, Akt, BDNF and TrkB expressions. Besides, enhanced the activities of antioxidant enzymes, plasma insulin level. Histomorphological observations also confirmed the protective effect of morin on neuronal degeneration. Morin 50mg once daily for 60 days was the most effective dose with a significant reduction in diabetes mediated complications in the brain associated with neuronal apoptosis and dysregulation of TrkB/Akt signalling.

Abstract
Fruits of Cornus mas and Cornus officinalis are representative plant materials traditionally used in Europe and Asia, respectively, in the treatment of diabetes and diabetes-related complications, which are often mediated by pathogenic inflammatory agents. Additionally, due to the fact of mutual infiltration of Asian and European medicines, the differentiation as well as standardization of traditional prescriptions seem to be crucial for ensuring the quality of traditional products. The objective of this study was a comparison of biological activity of extracts from fruits of C. mas and C. officinalis by an assessment of their effect on reactive oxygen species (ROS) generation in human neutrophils as well as cytokines secretion both in neutrophils (tumor necrosis factor α, TNF- α; interleukin 8, IL-8; interleukin 1β, IL-1β) and in human colon adenocarcinoma cell line Caco-2 (IL-8). To evaluate the phytochemical differences between the studied extracts as well as to provide a method for standardization procedures, a quantitative analysis of iridoids, such as loganin, sweroside, and loganic acid, found in extracts of Cornus fruits was performed with HPLC-DAD. All standardized extracts significantly inhibited ROS production, whereas the aqueous-alcoholic extracts were particularly active inhibitors of IL-8 secretion by neutrophils. The aqueous-methanolic extract of C. officinalis fruit, decreased IL-8 secretion by neutrophils to 54.64 ± 7.67%, 49.68 ± 6.55%, 50.29 ± 5.87% at concentrations of 5, 50, and 100 µg/mL, respectively, compared to LPS-stimulated control (100%). The aqueous extract of C. officinalis fruit significantly inhibited TNF-α release by neutrophils at concentrations of 50 and 100 µg/mL. On the other hand, the aqueous-ethanolic extract of C. mas fruit showed the propensity to increase TNF-α and IL-1β secretion. The modulatory activity of the Cornus extracts was noted in the case of secretion of IL-8 in Caco-2 cells. The effect was comparable with dexamethasone. The content of loganin in aqueous and aqueous-methanolic extract of C. officinalis fruit was higher than in the aqueous-ethanolic extract of C. mas fruit, which was characterized by a significant quantity of loganic acid. In conclusion, the immunomodulatory effect observed in vitro may partially confirm the traditional use of Cornus fruits through alleviation of the development of diabetes-derived inflammatory complications. Loganin and loganic acid are significant markers for standardization of C. mas and C. officinalis fruit extracts, respectively.

Abstract
Neuroinflammation and loss of neurotrophic support have key roles in the pathophysiology of diabetes-associated behavioral deficits (DABD). Sesamin (Ses), a major lignan of sesame seed and its oil, shows anti-hyperglycemic, anti-oxidative, and neuroprotective effects. The present study was designed to assess the potential protective effects of Ses against DABD and investigate the roles of inflammatory markers and neurotrophic factors in streptozotocin (STZ)-induced diabetic rats. After confirmation of diabetes, Ses (30 mg/kg/day; P.O.) or insulin (6 IU/rat/day; S.C.) was administered to rats for eight consecutive weeks. During the eighth-week period of the study, behavioral functions of the animals were evaluated by employing standard behavioral paradigms. Moreover, inflammation status, neurotrophic factors, and histological changes were assessed in the cerebral cortex and hippocampal regions of the rats. The results of behavioral tests showed that STZ-induced diabetes increased anxiety-/depression-like behaviors, decreased locomotor/exploratory activities, and impaired passive avoidance learning and memory. These DABD were accompanied by neuroinflammation, lack of neurotrophic support, and neuronal loss in both cerebral cortex and hippocampus of the rats. Intriguingly, chronic treatment with Ses improved all the above-mentioned diabetes-related behavioral, biochemical, and histological deficits, and in some cases, it was even more effective than insulin therapy. In conclusion, the results suggest that Ses was capable of improving DABD, which might be ascribed, at least partly, to the reduction of blood glucose level, inhibition of neuroinflammation, and potentiation of neurotrophic factors.

Abstract
The traditional Chinese medicines (TCMs) have been used to treat diseases over a long history, but it is still a great challenge to uncover the underlying mechanisms for their therapeutic effects due to the complexity of their ingredients. Based on a novel network pharmacology-based approach, we explored in this study the potential therapeutic targets of Liuwei Dihuang (LWDH) decoction in its neuroendocrine immunomodulation (NIM) function. We not only collected the known targets of the compounds in LWDH but also predicted the targets for these compounds using the balanced substructure-drug-target network-based inference (bSDTNBI), which is a target prediction method based on network inferring developed by our laboratory. A "target-(pathway)-target" (TPT) network, in which targets of LWDH were connected by relevant pathways, was constructed and divided into several separate modules with strong internal connections. Then the target module that contributes the most to NIM function was determined through a contribution scoring algorithm. Finally, the targets with the highest contribution score to NIM-related diseases in this target module were recommended as potential therapeutic targets of LWDH.

Meng Q, Yu X, Chen Q, Wu X, Kong X, Wang S, Cai D, Cheng P, Li Y, Bian H. Liuwei Dihuang soft capsules inhibits the phenotypic conversion of VSMC to prevent the menopausal atherosclerosis by up-regulating the expression of myocardin. JOURNAL OF ETHNOPHARMACOLOGY 2020; 246:112207. [PMID: 31476440 DOI: 10.1016/j.jep.2019.112207] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 08/01/2019] [Accepted: 08/29/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liuwei Dihuang (LWDH) is a classic prescription that has been used as a traditional medicinal formula for more than 1000 years in China. In clinical, LWDF is used for treating functional decline associated with senile disease and menopausal syndrome. Studies have demonstrated that LWDH could significantly improve estrogen level and ER expression, and suspend the process of atherosclerosis. However, the under mechanism of how LWDH suppressing VSMCs phenotypic conversion and proliferation through ER is still unknown. AIM OF THE STUDY This study was to reveal the under mechanism of how LWDH inhibits the phenotypic conversion of VSMCs. MATERIALS AND METHODS 24 ApoE-/- mice were divided into 4 groups: sham group, model group, E2 group, and LWDH group, and 6 C57BN/L6 mice were used as control group. The primary VSMCs were divided into control group, model group, E2 group, LWDH group, LWDH + MPP group, and LWDH + PHTPP group with or without control siRNA, ERα siRNA, ERβ siRNA, and myocardin siRNA. Oil red staining was used to evaluate the lipid deposition in the cardiac aorta. Serum chemistry analysis to test serum TG, TC, LDL, and HDL. Immunofluorescence staining was used to test α-SMA, osteopontin and F-actin. Immunohistochemical staining was performed to check out the myocardin in the cardiac aorta. The mRNA levels of α-SMA, osteopontin, ERα, ERβ, SRC3 and myocardin were detected by Real Time-PCR, and the protein expression levels of them were detected by Western blotting. Co-immunoprecipitation was proceed to test the interaction between ERα and SRC3 and SRC3 and myocardin. Flow cytometry was used to check out the cell cycle. Wound healing assay and Transwell were managed to evaluate the migration capacity of VSMCs. RESULTS In vivo administration of LWDH suppressed AS symptoms, decreases phenotypic marker of vascular endothelial cell, and increases phenotypic marker of VSMC in ovariectomized ApoE-/- female mice. Moreover, LWDH significantly increased the mRNA and protein expression levels of ERα, ERβ, SRC3 and myocardin in the cardiac aorta of ovariectomized ApoE-/- female mice. In vitro, LWDH altered cell cycle and reduced the elevated cyclinD protein expression migration capacity and in the model VSMCs. In addition, LWDH inhibited phenotypic conversion and promoted the expression of ER, SRC3, and myocardin of the primary VSMC phenotypic conversion model. Inhibition of ERα almost completely eliminated the impacts of LWDH on α- SMA and osteopontin. Furthermore, LWDH promoted the interaction between ERα and SRC3 and up-regulated the co-activation of SRC3 and myocardin. CONCLUSIONS LWDH could inhibit the phenotypic conversion of VSMCs in vitro and in vivo by increasing the activity of myocardin through up-regulating the expression of ERα and promoting the interaction between ERα and SRC3. Our research reveals the under mechanism of how LWDH inhibits the phenotypic conversion of VSMCs.

Life Sci 2019; 225:8-19. [PMID: 30943382 DOI: 10.1016/j.lfs.2019.03.078] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 03/23/2019] [Accepted: 03/30/2019] [Indexed: 12/16/2022]
Abstract
AIMS Diabetes mellitus (DM), a chronic metabolic disease, is associated with behavioral deficits. It has been suggested that ellagic acid (EA), a natural polyphenol compound, has potent anti-diabetic, anti-inflammatory, and neuroprotective properties. The present study was aimed to explore the potential protective effects of EA against diabetes-associated behavioral deficits and verified possible involved mechanisms. MAIN METHODS Fifty adult male Wistar rats were randomly divided into five groups: i.e., CON: normal rats treated with vehicle (5 ml/kg/day; P.O.), EA: normal rats treated with EA (50 mg/kg/day; P.O.), STZ: diabetic rats treated with vehicle (5 ml/kg/day; P.O.), STZ + INS: diabetic rats treated with insulin (6 IU/rat/day; S.C.), STZ + EA: diabetic rats treated with EA (50 mg/kg/day; P.O.). All the groups were under treatment for eight consecutive weeks. During the seventh and eighth weeks, behavioral functions of the rats were assessed by commonly used behavioral tests. Subsequently, pro- and anti-inflammatory cytokines, neurotrophic factors, and also histological changes were evaluated in both cerebral cortex and hippocampus of the rats. KEY FINDINGS Chronic EA treatment attenuated anxiety/depression-like behaviors, improved exploratory/locomotor activities, and ameliorated cognitive deficits in diabetic rats. These results were accompanied by decreased blood glucose levels, modulation of inflammation status, improved neurotrophic support, and amelioration of neuronal loss in diabetic rats. In some aspects, treatment with EA was even more effective than insulin therapy. SIGNIFICANCE The current work's data confirms that EA could potentially serve as a novel, promising, and accessible protective agent against diabetes-associated behavioral deficits, owing to its anti-hyperglycemic, anti-inflammatory, and neurotrophic properties.

[PMID: 30668418 DOI: 10.1016/j.phymed.2018.09.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2018] [Revised: 08/20/2018] [Accepted: 09/03/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Liuwei dihuang (LWDH), a widely used traditional Chinese herbal medicine, has been noticed for its potential on the improvement of diabetic complications including diabetic nephropathy and diabetic encephalopathy. However, whether LWDH can improve the effects of diabetic skeletal muscle atrophy has not yet been reported. PURPOSE The present study aimed to investigate the protective effects and mechanisms of the water extract of Liuwei dihuang (LWDH-WE) on skeletal muscle in cellular and animal models of diabetic muscle atrophy. STUDY DESIGN The muscle protective effects of LWDH-WE on diabetic muscle atrophy and weakness were examined in methylglyoxal (MG)-treated C2C12 myotubes and streptozotocin (STZ)-treated C57BL/6 mice, respectively. METHODS C2C12 myoblasts were differentiated by differentiation medium to form myotube structures. C2C12 myotubes were pre-treated with LWDH-WE 1 h before MG treatment. Diabetic mice were induced by single intraperitoneal injection of STZ (150 mg/kg) in C57BL/6 mice. Cell viability was determined by MTT and LDH assays. Protein expressions were detected by western blots. Morphological changes of cells were observed by an inverted microscope. Mitochondria membrane potential and reactive oxygen species (ROS) production were measured by flow cytometry. Muscle strength was evaluated by measuring grip strength of mice. RESULTS In C2C12 myotubes, LWDH-WE attenuated MG-induced cellular death and oxidative damage accompanied with improving mitochondrial membrane potential, inhibiting NADPH oxidase (Nox) activation, and ROS production. Moreover, LWDH-WE could attenuate MG-induced atrophy of C2C12 myotubes accompanied with regulating protein synthesis (IGF-1R, Akt, mTOR) and protein degradation (FoxO3a, atrogin-1, MuRF-1) signals. In STZ-induced diabetic mice, LWDH-WE improved body weight and skeletal muscle mass of mice. LWDH-WE also enhanced muscle strength of STZ-induced diabetic mice. Furthermore, LWDH-WE enhanced the improvement of insulin on gastrocnemius muscle mass and grip strength in STZ-treated mice. CONCLUSION LWDH-WE possesses skeletal muscle protection via reducing oxidative damage and regulating protein synthesis and degradation pathways in MG-induced atrophy of C2C12 myotubes. We also reveal the novel protection of LWDH-WE against STZ-induced reduction of muscle mass and muscle strength in mice.

Abstract
Among 65 species belonging to the genus Cornus only two, Cornus mas L. and Cornus officinalis Sieb. et Zucc. (Cornaceae), have been traditionally used since ancient times. Cornus mas (cornelian cherry) is native to southern Europe and southwest Asia, whereas C. officinalis (Asiatic dogwood, cornel dogwood) is a deciduous tree distributed in eastern Asia, mainly in China, as well as Korea and Japan. Based on the different geographic distribution of the closely related species but clearly distinct taxa, the ethnopharmacological use of C. mas and C. officinalis seems to be independently originated. Many reports on the quality of C. mas fruits were performed due to their value as edible fruits, and few reports compared their physicochemical properties with other edible fruits. However, the detailed phytochemical profiles of C. mas and C. officinalis, in particular fruits, have never been compared. The aim of this review was highlighting the similarities and differences of phytochemicals found in fruits of C. mas and C. officinalis in relation to their biological effects as well as compare the therapeutic use of fruits from both traditional species. The fruits of C. mas and C. officinalis are characterized by the presence of secondary metabolites, in particular iridoids, anthocyanins, phenolic acids and flavonoids. However, much more not widely known iridoids, such as morroniside, as well as tannins were detected particularly in fruits of C. officinalis. The referred studies of biological activity of both species indicate their antidiabetic and hepatoprotective properties. Based on the available reports antihyperlipidemic and anticoagulant activity seems to be unique for extracts of C. mas fruits, whereas antiosteoporotic and immunomodulatory activities were assigned to preparations of C. officinalis fruits. In conclusion, the comparison of phytochemical composition of fruits from both species revealed a wide range of similarities as well as some constituents unique for cornelian cherry or Asiatic dogwood. Thus, these phytochemicals are considered the important factor determining the biological activity and justifying the use of C. mas and C. officinalis in the traditional European and Asiatic medicine.

Abstract
BACKGROUND Subcutaneous injection of insulin can lead to problems such as hypoglycemia and edema. OBJECTIVE The purpose of this research was to evaluate the effect of oral insulin-coated trimethyl chitosan nanoparticles on control of glycemic status, IGF-1 and IGF-2 levels, and apoptosis in the hippocampus of rats with diabetes mellitus. METHODS Insulin-coated trimethyl chitosan nanoparticles were prepared by the polyelectrolyte complex method (PEC) method. Insulin loading content, loading efficiency, quantity and quality of particle size were evaluated. In vivo study was performed in different treatment groups of male Wistar rats with diabetes mellitus by insulin-coated trimethyl chitosan nanoparticles or subcutaneous injection of trade insulin. The duration of diabetes was eight weeks and the treatment was started after that time and continued for another two weeks. Body weight, fasting blood glucose (FBS), hippocampal apoptosis, and immunohistochemical (IHC) protein levels of IGF-1 and IGF-2 were assessed at the end of the experiments. RESULTS The size and polydispersity indexes were 533 nanometers and 0.533, respectively. Insulin coated trimethyl chitosan nanoparticles showed high loading efficiency (97.67% ) and loading content (48.83% ). The spherical shape of nanoparticle was confirmed by transmission electron microscopic (TEM). The amine, amide, ether and aliphatic groups were evaluated using FT-IR spectrophotometer which represented the correctness of the insulin coated trimethyl chitosan nanoparticles. Although the apoptotic index was not changed either by insulin-coated nano-particles or commercial insulin, in vivo results showed the efficacy of insulin-coated nanoparticles as well as commercial insulin in compensated weight loss, FBS and protein levels of IGF-1 and IGF-2. CONCLUSIONS The present study showed the efficacy of insulin coated nanoparticle in oral route manner that can be tested in Phase I- III clinical trials. However, a behavioral study could reveal the efficacy of insulin-loaded nanoparticles in the improvement of cognitive changes through the modulation of IGF-1 and IGF-2 levels in the hippocampus.

Deoxyelephantopin ameliorates lipopolysaccharides (LPS)-induced memory impairments in rats: Evidence for its anti-neuroinflammatory properties. Life Sci 2018; 206:45-60. [PMID: 29792878 DOI: 10.1016/j.lfs.2018.05.035] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 05/19/2018] [Accepted: 05/20/2018] [Indexed: 02/07/2023]
Abstract
AIM Neuroinflammation is a critical pathogenic mechanism of most neurodegenerative disorders especially, Alzheimer's disease (AD). Lipopolysaccharides (LPS) are known to induce neuroinflammation which is evident from significant upsurge of pro-inflammatory mediators in in vitro BV-2 microglial cells and in vivo animal models. In present study, we investigated anti-neuroinflammatory properties of deoxyelephantopin (DET) isolated from Elephantopus scaber in LPS-induced neuroinflammatory rat model. MATERIALS AND METHODS In this study, DET (0.625. 1.25 and 2.5 mg/kg, i.p.) was administered in rats for 21 days and those animals were challenged with single injection of LPS (250 μg/kg, i.p.) for 7 days. Cognitive and behavioral assessment was carried out for 7 days followed by molecular assessment on brain hippocampus. Statistical significance was analyzed with one-way analysis of variance followed by Dunnett's test to compare the treatment groups with the control group. KEY FINDINGS DET ameliorated LPS-induced neuroinflammation by suppressing major pro-inflammatory mediators such as iNOS and COX-2. Furthermore, DET enhanced the anti-inflammatory cytokines and concomitantly suppressed the pro-inflammatory cytokines and chemokine production. DET treatment also reversed LPS-induced behavioral and memory deficits and attenuated LPS-induced elevation of the expression of AD markers. DET improved synaptic-functionality via enhancing the activity of pre- and post-synaptic markers, like PSD-95 and SYP. DET also prevented LPS-induced apoptotic neurodegeneration via inhibition of PARP-1, caspase-3 and cleaved caspase-3. SIGNIFICANCE Overall, our studies suggest DET can prevent neuroinflammation-associated memory impairment and neurodegeneration and it could be developed as a therapeutic agent for the treatment of neuroinflammation-mediated and neurodegenerative disorders, such as AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bu Shen Yi Sui capsule (BSYSC), based on traditional Chinese formula Liu Wei Di Huang pill, is effective for the treatment of multiple sclerosis (MS) in clinical experience and trials. Our previous studies confirmed that BSYSC had the neuroprotective effect in MS and its animal model, experimental autoimmune encephalomyelitis (EAE); however, its mechanism of action was not clear. Thus, the effect of BSYSC on remyelination and the underlying mechanisms were investigated in the EAE mice. MATERIALS AND METHODS The EAE model was established by injecting subcutaneously myelin oligodendrocyte protein (MOG) 35-55 in mice. Mice were treated with BSYSC (3.02 g/kg) or vehicle daily by oral gavage for 40 days. The body weight and clinical score of mice were evaluated. Brain was observed by magnetic resonance imaging. The inflammation infiltrate of brain and spinal cord was determined by hematoxylin-eosin staining, while the structure of myelin sheath was visualized by transmission electron microscopy on days 23 and 40 post immunization (dpi), respectively. The protein and mRNA levels of platelets-derived growth factor receptor (PDGFR) α and 2', 3'-cyclic nucleotide-3'-phosphodiesterase (CNPase) were measured by immunohistochemistry, western blot and quantitative real-time polymerase chain reaction. The protein expressions of semaphorins (Sema) 3A, Neuropilin (NRP) - 1, leukemia inhibitory factor (LIF), LIF receptor (LIFR) and Nkx6.2 were further investigated by western blot. RESULTS BSYSC treatment improved the body weight and clinical score of EAE mice, alleviated inflammatory infiltration and nerve fiber injuries. It also protected the ultrastructural integrity of myelin sheath. BSYSC significantly increased expressions of PDGFRα and CNPase in mice with EAE on 40 dpi. Furthermore, BSYSC treatment increased the expressions of LIF, LIFR and Nkx6.2 and reduced Sema3A and NRP-1 in EAE mice on 40 dpi. CONCLUSIONS The data demonstrated that BSYSC exhibited the neuroprotective effect against EAE by promoting oligodendrocyte progenitor cells (OPCs) proliferation and differentiation, thus facilitating remyelination. Sema3A/NRP-1, LIF/LIFR and Nkx6.2 are likely contributed to the effects of BSYSC on OPCs.

Liuwei Dihuang, a traditional Chinese medicinal formula, inhibits proliferation and migration of vascular smooth muscle cells via modulation of estrogen receptors. Int J Mol Med 2018; 42:31-40. [PMID: 29693116 PMCID: PMC5979928 DOI: 10.3892/ijmm.2018.3622] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Accepted: 11/10/2017] [Indexed: 01/27/2023] Open
Abstract
The phenotypic modulation of vascular smooth muscle cells (VSMCs) serves an important role in atherosclerosis-induced vascular alterations, including vascular remodeling. However, the precise mechanisms underlying VSMC phenotypic modulation remain to be elucidated. Our previous study demonstrated that Liuwei Dihuang formula (LWDHF) could improve menopausal atherosclerosis by upregulating the expression of estrogen receptors (ERs). The present study examined the role of ERs in the effects of LWDHF on VSMC phenotypic modulation. VSMC proliferation and cell cycle progression were examined by MTT assay and flow cytometry, respectively. The expression levels of α-smooth muscle actin, osteopontin and ERs were determined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis. Cell ultrastructure was observed under an electron microscope. F-actin polymerization was detected by fluorescein isothiocyanate-phalloidin staining using fluorescence microscopy. A modified Boyden chamber assay was employed to assess VSMCs migration. Small interfering (si)RNA technology was used to examine the role of ERα in the effects of LWDHF on phenotypic modulation. The results indicated that LWDHF (3-12 µg/ml) inhibited proliferation and induced a cell cycle arrest in VSMCs treated with angiotensin II (Ang II; 100 nM) in a concentration-dependent manner. In addition, Ang II-stimulated migration of VSMCs and reorganization of actin were markedly inhibited by treatment with 12 µg/ml LWDHF. Results of RT-qPCR and western blotting demonstrated that LWDHF markedly stimulated transcription and expression of ERα and ERβ, and inhibited VSMC synthetic phenotype. Furthermore, LWDHF-induced inhibition of phenotypic switching was partially suppressed by tamoxifen, and transfection with ERα siRNA markedly abolished the effects of LWDHF on VSMC phenotypic switching. In conclusion, these results revealed that ERα served an important role in LWDHF-induced regulation of the VSMC phenotype, including proliferation and migration.

Effect of Transplantation of Bone Marrow Stromal Cell- Conditioned Medium on Ovarian Function, Morphology and Cell Death in Cyclophosphamide-Treated Rats. CELL JOURNAL 2017; 20:10-18. [PMID: 29308613 PMCID: PMC5759671 DOI: 10.22074/cellj.2018.4919] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Accepted: 03/12/2017] [Indexed: 12/13/2022]
Abstract
Objective Although stem cell transplantation has beneficial effects on tissue regeneration, but there are still problems
such as high cost and safety issues. Since stem cell therapy is largely dependent on paracrine activity, in this study,
utilization of transplantation of bone marrow stromal cells (BMSCs)-secretome instead of the cells, into damaged
ovaries was evaluated to overcome the limitations of stem cell transplantation.
Materials and Methods In this experimental study, BMSCs were cultured and 25-fold concentrated conditioned
medium (CM) from BMSCs was prepared. Female rats were injected intraperitoneally with cyclophosphamide (CTX)
for 14 days. Then, BMSCs and CM were individually transplanted into bilateral ovaries, and the ovaries were excised
after four weeks of treatment. The follicle count was performed using hematoxylin and eosin (H&E) staining and the
apoptotic cells were counted using TUNEL assay. Ovarian function was evaluated by monitoring the ability of ovulation
and the levels of serum estradiol (E2) and follicle-stimulating hormone (FSH).
Results Evaluation of the ovarian function and structure showed that results of secretome transplantation were almost
similar to those of BMSCs transplantation and there was no significant differences between them.
Conclusion BMSCs-secretome is likely responsible for the therapeutic paracrine effect of BMSCs. Stem cell-
secretome is expected to overcome the limitations of stem cell transplantation and become the basis of a novel therapy
for ovarian damage.

Abstract
This study is to clarify the protective role of α-lipoic acid in high-fat diet-induced cerebral damage mice. The mice were divided into 5 groups: normal control group, high-fat diet (HFD) group, low-dose α-lipoic acid group for prevention, high-dose α-lipoic acid group for prevention, and high-dose α-lipoic acid group for treatment. The groups' weights and blood glucose changes were monitored. We used HE staining to observe morphological changes in the cerebral cortex. The expression levels of the oxidative stress proteins SOD2, catalase, and the inflammatory pathway proteins p-JNK, p-ERK were measured by western blot and immunochemistry. Compared with the control group, the quantity of cortical neurons in the HFD group was decreased, and the samples exhibited retrogression. However, the lipoic acid significantly protected and promoted the cortical neurons survival. Moreover, compared with the HFD group, the expression levels of SOD2 and catalase in the three α-lipoic acid obtained groups were significantly increased. However, the expression levels of the inflammatory pathway proteins p-JNK and p-ERK were significantly decreased. These results indicate that theα-lipoic acid greatly protects the cortical neurons, and inhibited the oxidative stress and inflammatory reactions in the high-fat diet mice.

Abstract
Cognitive impairment has been recognized as a typical characteristic of neurodegenerative disease in diabetes mellitus (DM) and this cognitive dysfunction may be a risk factor for Alzheimer's disease (AD). Ferulic acid, a phenolic compound commonly found in a range of plants, has emerged various properties including anti-inflammatory and neuroprotective effects. In the present study, the protective activities and relevant mechanisms of ferulic acid were evaluated in diabetic rats with cognitive deficits, which were induced by a high-glucose-fat (HGF) diet and low dose of streptozotocin (STZ). It was observed that ferulic acid significantly increased body weight and decreased blood glucose levels. Meanwhile, ferulic acid could markedly ameliorate spatial memory of diabetic rats in Morris water maze (MWM) and decrease AD-like pathologic changes (Aβ deposition and Tau phosphorylation) in the hippocampus, which might be correlated with the inhibition of inflammatory cytokines release and reduction of protein tyrosine phosphatase 1B (PTP1B) expression. Moreover, the levels of brain insulin signal molecules p-IRS, p-Akt and p-GSK3β were also investigated. We found that ferulic acid administration restored the alterations in insulin signaling. In conclusion, ferulic acid exhibited beneficial effects on diabetes-induced cognition lesions, which was involved in the regulation of PTP1B and insulin signaling pathway. We suppose that PTP1B inhibition may represent a promising approach to correct abnormal signaling linked to diabetes-induced cognitive impairment.

Liuwei Dihuang soft capsules attenuates endothelial cell apoptosis to prevent atherosclerosis through GPR30-mediated regulation in ovariectomized ApoE-deficient mice. JOURNAL OF ETHNOPHARMACOLOGY 2017; 208:185-198. [PMID: 28709892 DOI: 10.1016/j.jep.2017.06.052] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Revised: 06/12/2017] [Accepted: 06/23/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liuwei Dihuang (LWDH), a classical traditional Chinese medicine prescription, has been widely used to prevent and to treat various diseases with symptoms of 'Kidney-Yin' deficiency syndrome for over 1000 years in China. It is commonly used to treat functional decline associated with senile disease and menopausal syndrome, especially memory decline, insomnia, diabetes and osteoporosis. Modern experimental pharmacological studies indicated that the mechanism of LWDH treatment of menopausal syndrome may be associated with enhanced estrogenic effects. However, little attention has been paid to the potential impact of LWDH on atherosclerosis (AS) associated with female menopause. The aim of this study was to evaluate the preventive effects of LWDH intake on an animal model of female menopause AS and to explore the underlying molecular mechanism. MATERIALS AND METHODS ApoE-/- mice were randomly divided into 4 groups, with C57BN/L6 mice as the control group. All ApoE-/- mice were ovariectomized (Ovx) one week prior to oral administration and initiation of high-fat diet. C57BL/6 mice were given sham operation and maintained on normal diet. The three administered groups were given simvastatin (4mg/kg via i.g.) and LWDH (4.5, 9.0g/kg via i.g.) every day for 14 weeks. Atherosclerotic lesions in the aortic root were determined by oil red O staining and hematoxylin-eosin staining. α-Actin and CD68 in atherosclerotic lesions were detected by immunohistological assay. Serum lipids and homocysteine (Hcy) levels were measured in the 14th week. The cleaved caspase-3, C/EBP homologous protein (CHOP) and G protein coupled estrogen receptor 30 (GPR30) expressions in the aortic arch endothelium were determined by immunohistochemistry and Western blot. The inhibitory effect of LWDH-medicated (20%, 12h) on Hcy (20%, 24h)-induced apoptosis of human umbilical vein endothelial cells (HUVECs) was examined by flow cytometry and Hoechst 33258 staining. Intracellular ROS production, nitric oxide release, and endothelial NO synthase (eNOS) activity were measured with or without LWDH-medicated serum pretreatment. In addition, CHOP, glucose-regulated protein GPR30, 78 (Grp78), Bcl-2, Bax and cleaved caspase-3 were analyzed by Western blot. Finally, the influence of G15, a specific antagonist of GPR30, on the protective effect of LWDH on endothelial cells was investigated. RESULTS In vivo administration of LWDH prevented plaque formation and reduced plasma lipid and Hcy levels. LWDH inhibited CHOP and cleaved caspase-3 expression in vivo and in vitro while maintaining GPR30 expression. In vitro study showed that Hcy-induced HUVECs apoptosis was weakened by LWDH-medicated serum pretreatment. Treatment with LWDH-medicated serum significantly upregulated NO release and eNOS activity in HUVECs. In addition, LWDH-medicated serum treatment optimized the balance between Bax and Bcl-2, and attenuated intracellular ROS production. G15 reversed the protective effect of LWDH on endothelial cells and the changes of apoptosis-related proteins. CONCLUSIONS LWDH treatment can significantly reduce plaque formation in an animal model of menopausal AS. The mechanism may be inhibition of Hcy-induced endothelial cell apoptosis by modulating GPR30. Hence, LWDH can potentially be used to prevent AS-related vascular disease in menopausal women.

Abstract
AIM To investigate the inhibitory effect of Liuwei Dihuang Pill (LDP) on gastric tumorigenesis induced by N-methyl-N-nitrosourea (MNU) in diabetic mice.
METHODS Four-week-old mice were divided into four groups: A, 12 db/m mice treated with MNU and saline, as the non-diabetic control; B, 12 db/db mice treated with MNU and saline, as the diabetic control; C, 12 db/db mice treated with MNU and metformin, as the positive control; and D, 12 db/db mice treated with MNU and LDP. MNU was administrated for 20 wk to induce gastric carcinogenesis. LDP was administrated for 10 wk for improvement of insulin resistance. Body weight and food intake were measured every week. Blood samples were collected for assays of fasting blood glucose, insulin, insulin-like growth factor (IGF)-1, adiponectin and leptin. Stomach tissues were collected for histopathological analysis, immunohistochemical staining of Ki67, quantitative reverse transcription-polymerase chain reaction and western blotting.
RESULTS The incidence of MNU-induced gastric dysplasia was significantly elevated in diabetic (db/db) mice relative to the control (db/m) mice. The incidence of gastric dysplasia was significantly reduced by LDP with suppression of cell proliferation, as demonstrated by a decrease in Ki67 staining. Hyperglycemia, hyperinsulinemia and serum IGF-1 were inhibited by LDP. Expression of IGF-1 and insulin receptor mRNAs was decreased, phosphorylation of IGF-1 receptor and AKT protein was reduced in the stomach tissues by LDP. In addition, adiponectin was increased and leptin was decreased in the serum by LDP.
CONCLUSION LDP decreased risk of gastric dysplasia in type 2 diabetic mice by down-regulation of IGF and insulin activity and correction of adipokines disorders.

Abstract
Adult neurogenesis plays the important roles in animal cognitive and emotional behaviors. Abnormal proliferation and differentiation of neural stem cells (NSCs) usually associate with the neural dysfunctions induced by different brain disorders. Therefore, targeting neurogenic factors could be a promoting strategy for neural regeneration and brain repair. Importantly, epidemiological studies suggest metabolism disorders like diabetes and obesity significantly increase the risk of neurological and psychiatric diseases. A large number of studies indicate that metabolic factors could serve as the modulators to adult neurogenesis, providing the potentials of metabolic factors to regulate NSCs growth and neural regeneration therapy. This chapter reviews the current studies on the roles of metabolic factors in modulating adult neurogenesis and evaluates the potentials of Chinese Herbal Medicine (CHM) for the treatment of neurological or psychiatric disorders by targeting the metabolic factors. Traditional Chinese Medicine (TCM) including CHM and acupuncture is now widely applied for the treatment of metabolic diseases, and neurological diseases in Asia, because its' therapeutic principles meet the multiple targets and complexity characteristics of most neurological disorders. Different studies indicate that there are many active compounds perform the regulations to metabolic factors and promoting neurogenesis. This chapter systematically summarizes the current progress and understanding of the active compounds and their underlying mechanisms of CHM formulas for promoting neurogenesis. Many CHM formulas and their active ingredients that originally used for metabolic disorders show the promising effects on mediating neurogenesis and brain repair for the treatments of neurodegenerative diseases. Therefore, further investigations about the relationship between neurogenesis and metabolic regulations of CHM will bring new insights into understanding the mechanisms of adult neurogenesis and provide great opportunities to develop new therapeutic strategies for neurological diseases. Those studies will provide scientific guidance to develop the drugs from TCM resource.

Abstract
Two natural compounds alisol A 24-acetate (24A) and alisol B 23-acetate (23B) are abundant in Rhizoma alismatis. In the present study, we evaluated the induction of 24A and 23B on apoptosis and possible nephrotoxicity of human renal proximal tubular (HK-2) cells by activating autophagy and also explored its regulation on PI3K/Akt/mTOR signaling pathway. Presently, Clusterin, Kim-1, and TFF-3 were considered to be new bioindicators of nephrotoxicity. Interestingly, the protein expression and mRNA levels of Clusterin, Kim-1 and TFF-3 could be significantly increased by 23B and 24A in vivo and in vitro. Furthermore, cell apoptosis could be triggered by 23B and 24A via significantly decreasing the protein expression and mRNA levels of Bcl-2 and Bcl-xl. Autophagy of HK-2 cells could be induced by both 23B and 24A via significantly enhancing the ratio of LC3II/LC3I, the protein expression of Beclin-1 as well as the mRNA levels of LC3 and Beclin-1. Meanwhile, PI3K/Akt/mTOR signaling pathway could be inhibited by these two compounds. An autophagy inhibitor, 3-methyladenine, could partially reverse cell viability and conversely change the ratio of LC3II/LC3I and the protein expression of Bcl-2 and Kim-1. Thus this study helped to understand that 23B and 24A induced autophagy resulted in apoptosis and nephrotoxicity through inhibiting PI3K/Akt/mTOR signaling pathway, facilitating further studies for nephrotoxicity induced by these two compounds and could be beneficial for safe use of Rhizoma alismatis in clinic.

Abstract
Jiawei Shenqi-wan (JSQW), which comprises Shenqi-wan and two additional medicinal herbs, has been widely used for the treatment of various growth impairments, including cerebral palsy. In the present study, JSQW was administered to hypoxic-ischemic Sprague-Dawley rats that underwent treadmill training from 4-7 weeks of age to examine the beneficial effects of combined JSQW and treadmill therapy. Behavioral examinations were performed and a significant improvement in cylinder test performance was observed in rats treated with treadmill training compared with hypoxic-ischemia rats (P<0.05), as well as a significant improvement in passive avoidance test performance for rats treated with JSQW (P<0.05). The thickness of the corpus callosum and the integrated optical density (IOD) of myelin basic protein (MBP) were significantly increased by treatment with treadmill therapy alone (P<0.01 and P<0.001, respectively) and treatment with both JSQW and treadmill significantly increased the IOD of MBP compared with hypoxic-ischemia rats (P<0.001). Western blot analysis revealed that the expression of neuronal nuclei (NeuN) and doublecortin (Dcx) significantly decreased (P<0.001 and P<0.05, respectively) and MBP expression markedly decreased in the ipsilateral subventricular zone of hypoxic-ischemic rats compared with the control group; however, the expression of NeuN was significantly recovered by treatment with both JSQW and treadmill training (P<0.05). Furthermore, Dcx expression was significantly recovered by treatment with JSQW (P<0.05), and MBP expression was significantly restored by treatment with treadmill training (P<0.01). In the immunohistochemical analyses, a significant increase in the number of bromodeoxyuridine (BrdU) positive cells in this region was observed in treadmill-treated rats (P<0.05), whereas significant increases in the number of Brdu/Dcx or NeuN or glial fibrillary acidic protein double-positive cells were observed only in the group co-treated with JSQW and treadmill (P<0.01, P<0.05 and P<0.001, respectively). These results suggest that JSQW and treadmill training may contribute to behavior recovery following hypoxic-ischemia, and JSQW treatment was particularly effective in promoting memory function via enhancing the differentiation of neuronal progenitor cells. The results of the present study therefore suggest that JSQW may provide an additional treatment option for functional recovery with treadmill training in cerebral palsy.

Abstract
Diabetes mellitus is associated with cognitive dysfunction. Numerous previous studies have shown that type 1 diabetes-induced hyperglycaemia causes structural brain damage, such as a decrease in whole-brain grey matter. The impact of diabetes mellitus on the cerebral cortex is poorly understood and requires further clarification. In the present study, diabetes was induced via an intraperitoneal injection of streptozotocin (50 mg/kg). Hematoxylin and eosin (H&E) staining was performed to detect the morphological changes in the cerebral cortex, terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) staining was used to detect neuronal apoptosis and western blotting was performed to determine protein expression levels. Nine weeks after the induction of diabetes, the body weight was significantly lower and the blood glucose levels were significantly higher in the diabetic rats than in the control rats (P<0.05). H&E staining revealed nuclear chromatin condensation and cytoplasmic shrinkage in the cerebral cortex of the diabetic rats and TUNEL staining further indicated apoptotic changes in the cerebral cortex of the diabetic rats. The ratio of B-cell lymphoma 2 (Bcl-2) -associated X protein/Bcl-2 and the expression of cytochrome c and activated caspase-3 (cleaved caspase-3) were significantly increased, whereas the ratio of phosphorylated AKT/AKT was significantly decreased in the diabetic rats compared with that in the control rats (P<0.05). Taken together, these results suggested that diabetes mellitus may induce neuronal apoptosis in the cerebral cortex by downregulating AKT phosphorylation.

Abstract
Paeoniflorin is a natural monoterpene glycoside in Paeonia lactiflora pall with various biological properties including promising anti-inflammatory activity. Current evidences support that inflammatory reaction, oxidative stress, as well as abnormal insulin signaling in the hippocampus are potential causes of tau hyperphosphorylation and finally induce cognitive dysfunction. The present study aims to explore the effects of paeoniflorin on the cognitive deficits and investigate the underlying mechanisms in diabetic rats induced by a high-sucrose, high-fat diet and low dose of streptozotocin (STZ). Paeoniflorin treatment effectively improved the performance of diabetic rats in the Morris water maze test via decreasing escape latency and increasing the spent time in the target quadrant. Immunohistochemistry staining also had shown that tau hyperphosphorylation in the hippocampus was prevented after paeoniflorin administration. This function was correlated with its abilities of reducing the brain inflammatory cytokines (IL-1β and TNF-α), decreasing suppressor of cytokine signaling 2 (SOCS2) expressions and promoting insulin receptor substrate-1 (IRS-1) activity. Additionally, we also found paeoniflorin administration significantly promoted the phosphorylation levels of protein kinase B (Akt) and glycogen synthase kinase-3β (GSK-3β). Together, these results showed that paeoniflorin had beneficial effects on relieving diabetes-associated cognitive deficits via regulating SOCS2/IRS-1 pathway and might provide a feasible method for the treatment of diabetes-associated cognitive dysfunction.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disorder in which the death of brain cells leads to memory loss and cognitive decline. To reduce the death rate and improve the biological activity of neurocytes, neurotrophic factors (NTFs) exhibit therapeutic effect on AD. However, therapeutic application of exogenous NTFs in treatment of AD is largely limited due to short half-life, poor stability, etc. Various extracts of traditional Chinese medicine (TCM) have been shown to exhibit therapeutic effects on AD, and some of these effects are associated with regulation on the expression of nerve growth factor, brain-derived neurotrophic factor (BDNF), and glial cell line-derived neurotrophic factor (GDNF) and their associated receptors. This article reviews the progress on promotion of Panax ginseng, Rehmannia glutinosa Libosch., Epimedium, Polygala tenuifolia Willd, and seven other TCMs on secretion of NTFs during AD, with a view to preparation development and clinical application of these TCMs on AD.

Abstract
BACKGROUND Alzheimer's disease (AD) is one of the most prevalent neurodegenerative disorders characterized by neuronal loss in the brain and cognitive impairment. AD is now considered to be the third major cause of death in developed countries, after cardiovascular disease and cancer. Persimmon leaves are used as a popular folk medicine to treat hypertension, angina and internal haemorrhage in Cyangbhina, and it has been reported that ethyl acetate extract of persimmon leaves (EAPL) displays a potential therapeutic effect on neurodegenerative diseases. HYPOTHESIS/PURPOSE This study was designed to investigate the effects of EAPL on AD, to clarify the possible mechanism by which EAPL exerts its beneficial effects and prevents AD, and to determine the major constituents involved. STUDY DESIGN AD model was established by bilateral injection of Aβ1-42 into the hippocampus of rats. The cognitive performance was determined by the Morris water maze and step-down tests. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), apoptosis, total and phosphorylated c-Jun NH2-terminal kinase (JNK/p-JNK), caspase-3, Bax and Bcl-2 were determined. In addition, a sensitive and reliable LC-QTOF-MS method was applied to identify the major compounds present in EAPL. RESULTS EAPL at doses of 200mg/kg, 400mg/kg could markedly reduce the latency, significantly increase the time in the first quadrant and number of the target crossing times in Morris water maze test, markedly increase the latency and reduce the number of errors in the step-down test, significantly inhibit the reductions in SOD and GSH-Px activities, and increase the level of MDA. In addition, EAPL treatment attenuated neuronal apoptosis in the hippocampus, reduced the expression of p-JNK, caspase-3, and the relative ratio of Bax/Bcl-2. Meanwhile, 32 constituents were identified by LC-QTOF-MS/MS assays. CONCLUSION The results indicate that EAPL has a potent protective effect on cognitive deficits induced by Aβ in rats and this effect appears to be associated with the regulation of the antioxidative defense system and the mechanism of mitochondrial-mediated apoptosis. Furthermore, analysis of the LC-MS data suggests that flavonoids and triterpenoids may be responsible for the potential biological effects of EAPL.

Abstract
The diacid metabolite of norcantharidin (DM-NCTD) is clinically effective against hepatocellular carcinoma (HCC), but is limited by its short half-life and high incidence of adverse effects at high doses. We developed a DM-NCTD-loaded, folic acid (FA)-modified, polyethylene glycolated (DM-NCTD/FA-PEG) liposome system to enhance the targeting effect and antitumor potency for HCC at a moderate dose based on our previous study. The DM-NCTD/FA-PEG liposome system produced liposomes with regular spherical morphology, with mean particle size approximately 200 nm, and an encapsulation efficiency >80%. MTT cytotoxicity assays demonstrated that the DM-NCTD/FA-PEG liposomes showed significantly stronger cytotoxicity effects on the H22 hepatoma cell line than did PEG liposomes without the FA modification (P<0.01). We used liquid chromatography–mass spectrometry for determination of DM-NCTD in tissues and tumors, and found it to be sensitive, rapid, and reliable. In addition, the biodistribution study showed that DM-NCTD liposomes improved tumor-targeting efficiency, and DM-NCTD/FA-PEG liposomes exhibited the highest efficiency of the treatments (P<0.01). Meanwhile, the results indicated that although the active liposome group had an apparently increased tumor-targeting efficiency of DM-NCTD, the risk to the kidney was higher than in the normal liposome group. With regard to in vivo antitumor activity, DM-NCTD/FA-PEG liposomes inhibited tumors in H22 tumor-bearing mice better than either free DM-NCTD or DM-NCTD/PEG liposomes (P<0.01), and induced considerably more significant cellular apoptosis in the tumors, with no obvious toxicity to the tissues of model mice or the liver tissue of normal mice, as shown by histopathological examination. All these results demonstrate that DM-NCTD-loaded FA-modified liposomes might have potential application for HCC-targeting therapy.

Abstract
The prevalence of cognitive impairment in rheumatoid arthritis (RA) patients was increasingly serious nowadays. The purpose of the current study was to explore whether salidroside (Sal) could alleviate arthritis-induced cognition deficits and examine the relationship between the impairment and Rho/ROCK/NF-κB pathway. Collagen-induced arthritis (CIA) was established by the injection of chicken type II collagen (CII), complete Freund's adjuvant (CFA) and incomplete Freund's adjuvant (IFA). Arthritic lesions of CIA rats were assessed by arthritis index score, swelling of paws and histological analysis. Cognitive deficits symptoms of CIA rats were monitored through Morris water maze test. The contents of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) in hippocampus and serum were significantly reduced with salidroside (20 mg/kg, 40 mg/kg) treatment compared with those in the CIA group. In parallel, we demonstrated that the expressions of RhoA, ROCK1, ROCK2, p-NF-κBp65, p-IκBα, p-IKKα and p-IKKβ were enhanced accompanying the investigation arthritis-induced cognition deficits, which were remarkably down-regulated by salidroside and confirmed by the results obtained from western blot and immunohistochemistry. LC-MS/MS results ascertained that Sal could enter into the blood and brain tissues to exhibit the protective effect on arthritis-induced cognitive dysfunction. Therefore, it was assumed that Sal might be a potential therapeutic candidate to treat arthritis-induced brain cognition deficits through the regulation of Rho/ROCK/NF-κB signaling.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herb pair serves as the basic building block of a traditional Chinese medicine (TCM) formula. The rhubarb-gardenia herb pair (RGHP), composed of rhubarb and gardenia, has meaningful clinical effects to cure cholestasis diseases. This study was designed to confirm the expected synergistic effects of RGHP at pharmacodynamic and pharmacokinetic levels. MATERIALS AND METHODS Thirty male Sprague-Dawley rats were divided into control, model and drug-treated groups. After intragastrically administrated with α-naphthylisothiocyanate (ANIT) to induce cholestasis, rats were treated with rhubarb, gardenia or RGHP. For pharmacodynamic study, biochemical and histopathological tests were performed to assess the hepatoprotective effects. While for pharmacokinetic study, a LC-MS method was developed for determination of five main chemical markers, namely genipin, rhein, aloe emodin, emodin and chrysophanol in rat plasma. RESULTS The biochemical and histopathological tests suggested that RGHP exerted enhanced hepatoprotective effects against the ANIT-induced cholestasis compared with single herbs. The pharmacokinetic study indicated RGHP could significantly elevate systemic exposure level and prolong retention time of five markers in comparison with rhubarb or gardenia alone. CONCLUSIONS The present study demonstrated the synergistic effects of RGHP in ANIT-induced cholestatic rats at pharmacodynamic and pharmacokinetic levels, and has significant enlightenments for the rational use of the related TCM formulas containing RGHP.

Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized by progressive neuronal loss with amyloid β-peptide (Aβ) plaques. Despite several drugs currently used to treat AD, their beneficial effects on AD progress remains under debate. Here, we established a rapid in vivo screening system using Drosophila AD models to assess the neuroprotective activities of medicinal plants that have been used in traditional Chinese medicine. Among 23 medicinal plants tested, the extracts from five plants, Coriandrum sativum, Nardostachys jatamansi, Polygonum multiflorum (P. multiflorum), Rehmannia glutinosa, and Sorbus commixta (S. commixta), showed protective effects against the Aβ42 neurotoxicity. We further characterized the neuroprotective activity of ethanol extracts from P. multiflorum and S. commixta. Aβ42-expressing flies that we used showed AD neurological phenotypes, such as decreased survival and motility and increased cell death and reactive oxygen species level. However, feeding these flies extracts from P. multiflorum or S. commixta showed strong suppression of such phenotypes. Similar results were observed in human cells, so that the treatment of P. multiflorum and S. commixta extracts increased the viability of Aβ-treated SH-SY5Y cells. Moreover, 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside, one of the main constituents of P. multiflorum, also showed similar protective activity against Aβ42 cytotoxicity in both Drosophila and human cells. Taken together, our results suggest that both P. multiflorum and S. commixta have therapeutic potential for the treatment of neurodegenerative diseases, such as AD.

Abstract
The preventive and therapeutic mechanisms in multiple sclerosis are not clearly understood. We investigated whether Hyungbangpaedok-san (HBPDS), a traditional herbal medicine, has a beneficial effect in experimental autoimmune encephalomyelitis (EAE) mice immunized with myelin oligodendrocyte glycoprotein peptide (MOG35-55). Onset-treatment with 4 types of HBPDS (extracted using distilled water and 30%/70%/100% ethanol as the solvent) alleviated neurological signs, and HBPDS extracted within 30% ethanol (henceforth called HBPDS) was more effective. Onset-treatment with HBPDS reduced demyelination and the recruitment/infiltration and activation of microglia/macrophages in the spinal cord of EAE mice, which corresponded to the reduced mRNA expression of pro-inflammatory cytokines (TNF-α, IL–6, and IL–1β), iNOS, and chemokines (MCP–1, MIP–1α, and RANTES) in the spinal cord. Onset-treatment with HBPDS inhibited changes in the components of the blood-brain barrier such as astrocytes, adhesion molecules (ICAM–1 and VCAM–1), and junctional molecules (claudin–3, claudin–5, and zona occludens–1) in the spinal cord of EAE mice. Onset-treatment with HBPDS reduced the elevated population of CD4+, CD4+/IFN-γ+, and CD4+/IL–17+ T cells in the spinal cord of EAE mice but it further increased the elevated population of CD4+/CD25+/Foxp3+ and CD4+/Foxp3+/Helios+ T cells. Pre-, onset-, post-, but not peak-treatment, with HBPDS had a beneficial effect on behavioral impairment in EAE mice. Taken together, HBPDS could alleviate the development/progression of EAE by regulating the recruitment/infiltration and activation of microglia and peripheral immune cells (macrophages, Th1, Th17, and Treg cells) in the spinal cord. These findings could help to develop protective strategies using HBPDS in the treatment of autoimmune disorders including multiple sclerosis.

Abstract
Soybean isoflavones are beneficial for treating hormone-related diseases. Simultaneous consumption of soybean isoflavones and Liuwei Dihuang pills (LWPs) is effective for treating perimenopausal period syndrome. However, why the combination of isoflavones and LWPs is more effective than ingestion of each component alone remains unknown. Here, we show that enhanced estrogenic activities would appear when the ovariectomized rats were fed with a soybean diet in combination of LWPs treatment. Our further studies explored enhancements of Lactobacillus (19-fold) and Bifidobacterium (12-fold) contents in the intestine of rat and 1.84-fold higher intestinal β-glucosidase activity in LWPs treatment group compared with the control group. As a result, steady-state concentrations of genistein (1.20-fold), daidzein (1.36-fold), and equol (1.43-fold) in serum were significantly elevated in the combination group compared with the soybean alone group. The results present the first evidence of the mechanism of enhanced estrogenic activity of dietary soybean isoflavones in combination with LWPs. Our study indicates that alterations of gut bacteria after LWPs treatment play a key role in the enhanced estrogenic effect of dietary soybean, suggesting a direct relationship between dietary soybean, LWPs, and gut flora.

Abstract
Diabetes mellitus (DM) is a metabolic disorder affecting a large number of people worldwide. Numerous studies have demonstrated that DM can cause damage to multiple systems, leading to complications such as heart disease, cancer, and cerebrovascular disorders. Numerous epidemiological studies have shown that DM is closely associated with dementia and cognition dysfunction, with recent research focusing on the role of DM-mediated cerebrovascular damage in dementia. Despite the therapeutic benefits of antidiabetic agents for the treatment of DM-mediated cognitive dysfunction, most of these pharmaceutical agents are associated with various undesirable side-effects and their long-term benefits are therefore in doubt. Early evidence exists to support the use of traditional Chinese medicine (TCM) interventions, which tend to have minimal toxicity and side-effects. More importantly, these TCM interventions appear to offer significant effects in reducing DM-related complications beyond blood glucose control. However, more research is needed to further validate these claims and to explore their relevant mechanisms of action. The aims of this paper are (1) to provide an updated overview on the association between DM and cognitive dysfunction and (2) to review the scientific evidence underpinning the use of TCM interventions for the treatment and prevention of DM-induced cognitive dysfunction and dementia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhizoma alismatis (simplified as RA, "Zexie" in Chinese, ) is a well-known natural medicine with long history in Chinese medicine. As a traditional medicine in China, RA is an important part of many prescriptions and has been commonly used for treating a wide range of ailments related to dysuria, edema, nephropathy, hyperlipidaemia, diabetes, inflammation as well as tumor in clinical applications. Based on scientific literatures, the present paper aims to provide comprehensive and up-to date information about the traditional uses, phytochemistry, pharmacology, toxicology and quality control of RA as well as critical analysis of the research. The review will provide a new foundation and direction for the further studies of RA. MATERIALS AND METHODS All available information about RA was supplied by library database and electronic search (ScienceDirect, Web of Science, Pubmed, Google Scholar, etc.). The different types of useful information were collected and arranged in corresponding part of the paper. RESULTS Phytochemical studies showed that the main chemical composition of RA was the terpenoid including sesquiterpene, diterpene and triterpene. The crude extracts and isolated compounds from RA showed diverse pharmacological activities including diuretic, nephroprotective, anti-hyperlipidemic, anti-atherosclerotic, anti-cancer, anti-inflammatory and anti-oxidative activities. However, high-dose or long-term use of RA can lead to water-electrolyte imbalance, bloody urine, acidosis and even hepatotoxicity or nephrotoxicity, which have been proven by several studies. CONCLUSIONS Pharmacological researches show RA possessing various bioactivities including diuresis, nephroprotective effect, anti-hyperlipidemia, etc. However, more bioactive components especially diuretic and nephroprotective compounds need to be isolated and identified, and more rigorous researches on action mechanisms are required. More experiments in vitro or in vivo and clinical studies are encouraged to clarify correlation between traditional uses and modern applications, and the toxicity need to be further and precisely explored. In addition, a standardized fingerprint for RA is indispensable and emergent. These achievements will further expand to therapeutic potential and usage of RA and provide a powerful support for clinical use.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shensong Yangxin Capsule (SSYX), a traditional Chinese herbal medicine, has long been used clinically to treat arrhythmias in China. However, the effect of SSYX on interstitial fibrosis in diabetic cardiomyopathy is unknown. The objective of this study was to investigate the effects of SSYX on myocardial fibrosis in diabetic rats. MATERIALS AND METHODS The antifibrotic effect of SSYX was investigated in streptozocin (STZ)-induced diabetic rats with high fat-diet (HFD). Fasting blood glucose, heart weight/body weight (HW/BW) ratio, total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were measured. Echocardiography and histology examination were carried out to evaluate heart function. Expressions of Smad7, TGF-β1, collagen I (col-1), collagen III (col-3), MMP-2, MMP-9 and α-SMA mRNA in heart tissues were measured by real time polymerase chain reaction (PCR). TGF-β1, Smad2/3, p-Smad2/3 and Smad7 protein levels were measured by western blot analysis. Proliferation of cardiac fibroblast was detected via immunofluorescence. RESULTS SSYX markedly decreased HW/BW ratio and improved the impaired cardiac function of type-2 diabetes mellitus (T2DM) rats. Transmission electron microscopy (TEM), haematoxylin and eosin (HE) and Masson staining results showed that SSYX attenuated cardiac fibrosis and collagen deposition in T2DM rats. Moreover, mRNA levels of TGF-β1, col-1, col-3, MMP-2, MMP-9 and α-SMA were downregulated, whereas Smad7 expression was upregulated after treatment with SSYX in rats with cardiac fibrosis. Furthermore, SSYX decreased protein levels of TGF-β1 and p-Smad2/3, and increased Smad7 expression. CONCLUSION TGF-β1/Smad signaling is involved in the cardiac fibrosis in diabetic cardiomyopathy and SSYX inhibits fibrosis and improves cardiac function via suppressing this pathway. Therefore, SSYX might be considered as an alternative therapeutic remedy for diabetic cardiomyopathy.
