Abstract
BACKGROUND Diabetes Mellitus is an endocrine disorder that will affect, about 693 million adults by 2045 worldwide, (>50% increase from 2017). The conventional treatment of the disease, include the oral hypoglycemic drugs which are given in combination with other drugs and are known to possess various adverse effects like gastrointestinal disturbance, nausea, water retention etc. PURPOSE: Due to the urgent need of combating this disorder without side effects, the alternative and complementary therapies should be explored due to their natural origins and comparable safety. Herbal sources serve as new leads, due to the presence of phytoconstituents with potential therapeutic properties, efficacy and safety. In this review, we tried to summarise the polyphenolic phytoconstituents effective in the treatment of diabetic complications. METHODS A systematic literature search was conducted using 4 databases (Google scholar, Pubmed, Scopus, Embase) for the identification of relevant data. Search was performed using various key words such as "diabetes", "polyphenols", "marine sources","anti-diabetic polyphenols". The in vitro studies involving the cell lines used in diabetes and animal models were also considered for inclusion. Additional research papers were identified by reviewing abstracts, scrutinizing reference lists, and reviewing previously published review articles. RESULTS Polyphenols, a group of phytoconstituents are known worldwide for their tremendous antioxidant potential. So, various research groups have explored their mechanism and therapeutic value in diabetic complications, to improve the insulin sensitivity and glucose metabolism, in controlling the glycemic conditions. CONCLUSION Polyphenols exhibit effective therapeutic potential in managing diabetic complications through their multifaceted mechanism of action. They exhibit antioxidative, anti-inflammatory, and anti-glycemic properties, which collectively contribute to their beneficial effects in mitigating diabetic complications. Thus, the inclusion of polyphenols into the diet, may be cosidered as an approach of managing diabetes on long term basis. In this review, we have tried to identify polyphenols effective in diabetes and summarize their mechanism of action along with their potential, for the treatment of diabetic complications.

Abstract
Type 2 diabetes mellitus, nonalcoholic fatty liver disease (NAFLD), cardio-cerebrovascular diseases (CCVDs), hyperuricemia and gout, and metabolic-related sexual dysfunction are metabolic diseases that affect human health in modern society. Scientists have made great efforts to investigate metabolic diseases using cell models in vitro or animal models in the past. However, the findings from cells or animals are difficult to translate into clinical applications due to factors such as the in vitro and in vivo differences; the differences in anatomy, physiology, and genetics between humans and animals; and the differences in microbiome-host interaction. The Chinese have extensively used the medicated diet of traditional Chinese medicine (TCM) (also named as Yao-Shan of TCM, Chinese Yao-Shan et al.) to maintain or improve cardiometabolic health for more than 2,200 years. These ancient classic diets of TCM are essential summaries of long-term life and clinical practices. Over the past 5 years, our group has made every effort to collect and sort out the classic Yao-Shan of TCM from the ancient TCM literature since Spring and Autumn and Warring States Period, especially these are involved in the prevention and treatment of metabolic diseases, such as diabetes, NAFLD, CCVDs, hyperuricemia and gout, and sexual dysfunction. Here, we summarized and discussed the classic Yao-Shan of TCM for metabolic diseases according to the time recorded in the ancient literature, and revised the Latin names of the raw materials in these Yao-Shan of TCM. Moreover, the modern medicine evidences of some Yao-Shan of TCM on metabolic diseases have also been summarized and emphasized in here. However, the exact composition (in terms of ratios), preparation process, and dosage of many Yao-Shan are not standardized, and their main active ingredients are vague. Uncovering the mystery of Yao-Shan of TCM through modern biological and chemical strategies will help us open a door, which is ancient but now looks new, to modulate metabolic homeostasis and diseases.

Abstract
Methotrexate (MTX) is an immunosuppressant used for the treatment of cancer and autoimmune diseases. MTX has a major adverse effect, acute kidney injury, which limits its use. Mangiferin (MF) is a natural bioactive xanthonoid used as a traditional herbal supplement to boost the immune system due to its potent anti-inflammatory and antioxidant activity. The present study evaluates the protective effect of MF against MTX-induced kidney damage. Male Wistar rats received MTX to induce nephrotoxicity or were pretreated with MF for 10 constitutive days before MTX administration. MF dose-dependently improved renal functions of MTX-treated rats and this activity was correlated with increased renal expression of PPARγ, a well-known transcriptional regulator of the immune response. Pretreating rats with PPARγ inhibitor, BADGE, reduced the reno-protective activity of MF. Furthermore, MF treatment significantly reduced MTX-induced upregulation of the pro-inflammatory (NFκB, interleukin-1ß, TNF-α, and COX-2), oxidative stress (Nrf-2, hemoxygenase-1, glutathione, and malondialdehyde), and nitrosative stress (nitric oxide and iNOS) markers in the kidney. Importantly, BADGE treatment significantly reduced the anti-inflammatory and antioxidant activity of MF. Therefore, our data suggest that the reno-protective effect of MF against MTX-induced nephrotoxicity is due to inhibition of inflammation and oxidative stress in a PPAR-γ-dependent manner.

Abstract
Diabetes mellitus has become one of the most challenging public health problems today. There are still various deficiencies that remain in existing therapeutic drugs. With increasing prevalence and mortality rates, more effective therapeutic agents are required for treatment clinically. As a kind of polyphenol and as a natural product, mangiferin has numerous pharmacological and excellent effects. In this review, the underlying mechanisms of mangiferin on diabetes mellitus and complications will be summarized. Moreover, mangiferin belongs to the BSC IV class and the clinical application and development of mangiferin are limited due to its poor aqueous solubility and fat solubility as well as low bioavailability. Our review also elaborated on improving the solubility of mangiferin by changing the dosage form and introduced the existing results, which hope to provide useful reference for mangiferin for further treating diabetes. In conclusion, mangiferin might be a potential adjuvant therapy for the treatment of diabetes mellitus and complications in the future.

Abstract
Although mangiferin has a number of documented beneficial effects, there are no systematic reviews or meta-analyses of its effects in diabetic animal models. To investigate the effects of oral administration of mangiferin on blood glucose levels, body weight, and total cholesterol and triglycerides levels in diabetic animal models, a meta-analysis was conducted and the underlying mechanisms were reviewed. Studies from 6 databases (PubMed, Web of Science, Embase, Cochrane Library, and CNKI (China National Knowledge Infrastructure), and Wanfang Med) were searched from inception to April 2020. After article screening, a total of 19 articles were included in this meta-analysis. The meta-analysis was performed using RevMan 5.3 and STATA 14.0 software. The overall pooled estimate of standardized mean difference (SMD) of mangiferin's effect on blood glucose was -1.27 (95% confidence interval [CI]: -1.71, -0.82, P < .00001). Body weight increased in lean diabetic animals with an SMD of 1.41 (95% CI: 0.57, 2.25; P = .001), while it decreased in obese diabetic animals with an SMD of -0.92 (95% CI: -1.69, -0.14; P = .02). Mangiferin intake reduced serum total cholesterol and triglycerides levels with SMDs of -1.02 (95% CI: -1.43, -0.61; P < .001) and -1.24 (95% CI: -1.70, -0.79; P < .001), respectively. The meta-analysis suggests that oral intake of mangiferin has a significant antidiabetic effect in animal models, and the systematic review suggested that this function might be attributed to its anti-inflammatory and antioxidative properties, as well as to its function of improving glycolipid metabolism and enhancing insulin signaling.

Abstract
Wound repair and regeneration is a complex orchestrated process, comprising several phases interconnecting various cellular events and triggering multiple intracellular molecular pathways in damaged cells and tissues. In several metabolic disorders including diabetes mellitus, delay in wound healing due to elevated levels of cellular stress poses a key challenge. Several therapeutic wound dressing materials and strategies including hyperbaric oxygen therapy and negative pressure wound therapy have been developed to accelerate repair and restore cellular homeostasis at the wound site. Further, tremendous progress has been made in identification of transcriptional regulators involved in the process of wound healing. Nuclear factor erythroid 2-related factor 2 (Nrf2), a redox sensitive transcription factor, is the key regulator of intracellular redox homeostasis which induces the expression of cytoprotective genes and increases the production of antioxidants that scavenge free radicals. Activators of Nrf2 have been reported to combat oxidative stress and enhance the process of wound healing in several pathophysiological conditions, including diabetes and its complications such as diabetic foot ulcer, and chronic kidney disease, and diabetic nephropathy. Several bioactive compounds have been reported to reduce cellular stress, and thus accelerate cell proliferation, neovascularization results in repairing damaged tissues by the activation of the transcription factor, Nrf2. This review is focused on the strategies for diabetic wound healing and the highlights the role of bioactive compounds that activate the Nrf2 signaling and revitalize the cellular and molecular mechanism in the chronic wound niche, regulate and restore redox homeostasis thereby promoting wound repair and regeneration.

Abstract
Diabetic nephropathy (DN) is one of the notorious diabetes associated complications. Despite many therapeutic strategies available, metabolic control of DN continues to poses a challenge. In this study, the interactions of mangiferin with selected oral hypoglycemic drugs, metformin and gliclazide to effectively alleviate the symptoms of renal injury in DN are evaluated. Male Sprague Dawley rats were used as experimental model and type II diabetes was induced by administration of high fat diet and low dose streptozotocin. Oral intervention of mangiferin with metformin and gliclazide for a period of 28 days was given to diabetic rats. At the end of the treatment period, biochemical parameters, kidney function markers, anti-oxidant enzymes levels, oxidative stress mediated gene expression and histology were analysed. Significant reduction in the serum biochemical markers (glucose, urea and creatinine) were observed in the groups treated with combination drugs. Marked improvement in the combination treated groups in terms of inflammation and oxidative damage in the gene (TNFα, NFκB, TGFβ, VEGF, PKC) and protein expression (NFκB, VEGF) were noted in the kidney tissue alleviating the symptoms of DN. These results were further corroborated with histopathological results. Scientific data in the present study reveals that the combinations of mangiferin with the oral hypoglycemic drugs have been favorable in alleviating renal injury. Hence, a combination therapy to alleviate the vascular complication, diabetic nephropathy may be considered as a possible therapeutic strategy by including natural phytocompounds as an add on therapy to conventional oral hypoglycemic drugs.

Abstract
Berberine is a quaternary isoquinoline alkaloid that has been isolated from numerous plants which are still in use today as medicine and herbal supplements. The great deal of enthusiasm for intense research on berberine to date is based on its diverse pharmacological effects via action on multiple biological targets. Its poor bioavailability resulting from low intestinal absorption coupled with its efflux by the action of P-glycoprotein is, however, the major limitation. In this communication, the chemical approach of improving berberine's bioavailability and pharmacological efficacy is scrutinised with specific reference to type-2 diabetes and associated diseases such as hyperlipidaemia and obesity. The application of modern delivery systems, research from combination studies to preparation of berberine structural hybrids with known biologically active compounds (antidiabetic, antihyperlipidaemic and antioxidant), as well as synthesis approaches of berberine derivative are presented. Improvement of bioavailability and efficacy through in vitro and ex vivo transport studies, as well as animal models of bioavailability/efficacy in lipid metabolism and diabetes targets are discussed.

Mangiferin Ameliorates Hyperuricemic Nephropathy Which Is Associated With Downregulation of AQP2 and Increased Urinary Uric Acid Excretion. Front Pharmacol 2020; 11:49. [PMID: 32116724 PMCID: PMC7020245 DOI: 10.3389/fphar.2020.00049] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Accepted: 01/15/2020] [Indexed: 12/28/2022] Open
Abstract
Hyperuricemia is characterized by abnormally high level of circulating uric acid in the blood and is associated with increased risk of kidney injury. The pathophysiological mechanisms leading to hyperuricemic nephropathy (HN) involve oxidative stress, endothelial dysfunction, inflammation, and fibrosis. Mangiferin is a bioactive C-glucoside xanthone, which has been exerting anti-inflammatory, anti-fibrotic, and antioxidative effects in many diseases. This study aimed to evaluate the effect of mangiferin treatment in HN. In a mouse model of HN, we observed lower circulating urate levels and ameliorated renal dysfunction with mangiferin treatment, which was associated with reduced renal inflammation and fibrosis. We next investigated the mechanism of urate lowering effect of mangiferin. Metabolic cage experiment showed that mangiferin-administrated mice excreted significantly more urinary uric acid due to elevated urine output, but no marked change in urine uric acid concentration. Expressions of water channels and urate transporters were further assessed by western blot. Renal AQP2 expression was decreased, yet urate transporters URAT1, GLUT9, and OAT1 expressions were not affected by mangiferin in HN mice. Moreover, mangiferin treatment also normalized xanthine oxidase and SOD activity in HN mice, which would decrease uric acid synthesis and improve oxidative stress, respectively. Therefore, our results reveal a novel mechanism whereby mangiferin can reduce serum uric acid levels by promoting AQP2-related urinary uric acid excretion. This study suggested that mangiferin could be a multi-target therapeutic candidate to prevent HN via mechanisms that involve increased excretion and decreased production of uric acid and modulation of inflammatory, fibrotic, and oxidative pathways.

Abstract
BACKGROUND Diabetes and its related complications are now a global health problem without an effective therapeutic approach. There are many herbal medicines which have attracted much attention as potential therapeutic agents in the prevention and treatment of diabetic complications due to their multiple targets. AIM The aim of this study is to review available knowledge of mangiferin focusing on its mode of action. METHODS Mangiferin was extensively reviewed for its antidiabetic activity using online database like Scopus, PubMed, and Google Scholar as well as some offline textbooks. A critical discussion based on the mechanism of action and the future perspectives is also given in the present manuscript. RESULTS Mangiferin is a natural C-glucoside and mainly obtained from its primary source, the leaves of mango tree (Mangifera indica L.). Therapeutic and preventive properties of mangiferin include antimicrobial, anti-inflammatory, antioxidative, antiallergic, neuroprotective, and cognition-enhancing effects. It dissolves well in water, so it can be easily extracted into infusions and decoctions and hence, a number of researches have been made on the therapeutic effect of this molecule. Recently, mangiferin has been proved to be an effective remedy in diabetes and diabetes-related complications. It is a beneficial natural compound for type 2 diabetes mellitus as it improves insulin sensitivity, modulates lipid profile and reverts adipokine levels to normal. CONCLUSION This study concludes that mangiferin has the potential to treat diabetes and it can be developed as a therapeutic agent for diabetes and the complications caused by diabetes.

Abstract
Renal interstitial fibrosis is considered to be the typical manifestation of diabetic nephropathy (DN). Mangiferin has shown positive effect on the prevention or treatment of diabetes and its complications. The aim of this study was to explore the inhibitive effect and mechanism of mangiferin on renal interstitial fibrosis in diabetic mice. Streptozotocin- (STZ-) induced diabetic mice were treated with mangiferin (15, 30, and 60 mg/kg/d) for 4 weeks. The morphology of kidneys was observed by Masson's trichrome staining, and the biochemical parameters (fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), blood urea nitrogen (BUN), serum creatinine (SCr), and urine protein) were determined by kits. In addition, the levels of inflammatory cytokines (tumor necrosis factor-α (TNF-α), interleukin- (IL-) 6, and IL-1β), antioxidant enzymes (SOD, CAT, and GSH-Px), MDA, and ROS were assessed. Furthermore, the expressions of fibronectin (FN), collagen I (Col I), and α-SMA were measured by immunohistochemistry. Regulations of TGF-β1 and the PTEN/PI3K/Akt pathway were detected by Western blotting. Treatment with mangiferin significantly ameliorated renal dysfunction in diabetic mice, as evidenced by the increase in body weight and decreases in FBG, TG, TC, BUN, SCr, urine protein, and the kidney to body weight ratio (KW/BW). Furthermore, mangiferin treatment prevented renal interstitial fibrosis evidenced by decreases in the positive expression of FN, Col I, and α-SMA, in comparison with morphological changes in the renal tissue. Meanwhile, mangiferin increased antioxidant enzymes, reduced the TNF-α, IL-6, and IL-1β, as well as MDA and ROS. Additionally, mangiferin administration also downregulated TGF-β1, upregulated PTEN, and decreased the phosphorylation of both PI3K and Akt. These findings demonstrate that mangiferin may reduce inflammation and oxidative stress in DN, thereby inhibiting the renal interstitial fibrosis by reducing the TGF-β1-mediated elevation of Col I, FN, and α-SMA through the PTEN/PI3K/Akt pathway.

Abstract
In diabetes, the increasing blood glucose levels through oxidative stress, with increase in inflammatory cytokines and growth factors, such as TGF-β1, can cause long-term complications, including nephropathy. Subcutaneous injection of insulin is a common method used to treat Type 1 diabetes, which can lead to problems such as hypoglycemia and edema. In the present study, we examined the effect of insulin in its two injectable and oral forms on the expression of TGF-β1 and fibronectin in kidney tissue of STZ diabetic rats. A total of 25 male Wistar rats were randomly divided into 5 groups: C: normal control, D: diabetic control, D+NP, oral insulin-loaded trimethyl chitosan nanoparticles (8 IU/kg), and subcutaneously injected insulin (8 IU/kg). The groups were treated from 8th to 10th weeks. After 10 weeks, FBS was measured. Also, the TGF-β1 and fibronectin mRNA expression and serum TGF-β1 protein were examined in the kidney tissue. Structural changes in the kidney tissue were studied using H&E staining. After 10 weeks of diabetes induction, the rats showed significant change in blood glucose, weight, serum TGF-β1, Fibronectin and TGF-β1 expression of kidney in diabetic groups (p < 0.05). Oral insulin-loaded trimethyl chitosan nanoparticles treatment, similar to injected insulin, significantly ameliorate blood glucose and rats' weight (p < 0.05). However, the reduction in fibronectin and TGF-β1 expression and serum TGF-β1 protein by both treatments was not statistically significant (p > 0.05). These data showed that oral insulin-loaded trimethyl chitosan nanoparticles were better therapeutic intervention than injected insulin for Type 1 diabetes.

Abstract
BACKGROUND Available data indicate that diabetes mellitus leads to elevated cost of healthcare. This imposes a huge economic burden on households, societies, and nations. As a result many Ghanaians, especially rural folks, resort to the use of phytomedicine, which is relatively less expensive. This paper aims at obtaining information on plants used in Ghana to treat diabetes mellitus, gather and present evidence-based data available to support their uses and their mechanisms of action, and identify areas for future research. METHOD A catalogue of published textbooks, monographs, theses, and peer-reviewed articles of plants used in Ghanaian traditional medicine between 1987 and July 2018 for managing diabetes mellitus was obtained and used. RESULTS The review identified 76 plant species belonging to 45 families that are used to manage diabetes mellitus. Leaves were the part of the plants frequently used for most preparation (63.8%) and were mostly used as decoctions. Majority of the plants belonged to the Euphorbiaceae, Lamiaceae, Asteraceae, and Apocynaceae families. Pharmacological data were available on 23 species that have undergone in vitro studies. Forty species have been studied using in vivo animal models. Only twelve plants and their bioactive compounds were found with data on both preclinical and clinical studies. The records further indicate that medicinal plants showing antidiabetic effects did so via biochemical mechanisms such as restitution of pancreatic β-cell function, improvement in insulin sensitivity by receptors, stimulating rate of insulin secretion, inhibition of liver gluconeogenesis, enhanced glucose absorption, and inhibition of G-6-Pase, α-amylase, and α-glucosidase activities. CONCLUSION This review contains information on medicinal plants used to manage diabetes mellitus, including their pharmacological properties and mechanisms of action as well as models used to investigate them. It also provides gaps that can form the basis for further investigations and development into useful medications for effective treatment of diabetes mellitus.

Abstract
Background Hypoxic-ischemic brain injury in the perinatal period is a main cause of perinatal mortality and neurologic complications in neonates and children. Recent studies have focused on the neuroprotective effect of anesthetic drugs. The volatile anesthetic isoflurane has been shown to exert neuroprotective effects in cerebral ischemia. Mangiferin is a natural polyphenol with various pharmacological properties, including antioxidant and ant-tumor effects. This study aimed to determine whether mangiferin potentiates the neuroprotective effects of isoflurane and also if mangiferin when administered alone exerts neuroprotective effects following hypoxic-ischemic brain injury. Material/Methods Sprague-Dawley rats were subjected to cerebral hypoxic ischemia on postnatal day 10 (P10). Mangiferin (50, 100, or 200 mg/kg b.w.) was intragastrically administered from P3 to P12 and 1 h prior to insult on the day of ischemic induction. At 3 h after hypoxia-ischemia (HI) insult, separate groups of rat pups were exposed to isoflurane (1.5%) for 6 h. Following 48 h of HI, the rats were sacrificed and brain tissues were used for analysis. Results Mangiferin treatment attenuated neuronal apoptosis and reduced cerebral infarct volume. The expression of cleaved caspase-3 and apoptotic cascade proteins were regulated. The levels of reactive oxygen species (ROS) and malondialdehyde were reduced by mangiferin and/or isoflurane exposure. The levels of antioxidant glutathione were considerably raised under HI injury, which was modulated by mangiferin and isoflurane exposure. The PI3K/Akt signaling pathway, which was downregulated following HI insult, was activated by mangiferin and/or isoflurane. Conclusions This study reveals the potent neuroprotective efficacy of mangiferin against HI-induced brain injury via effectively modulating apoptotic pathways, ROS levels, and PI3K/Akt cascades while potentiating protective effects of isoflurane.

Abstract
Previous studies by our group on mangiferin demonstrated that it exerts an antihyperglycemic effect through the regulation of cell cycle proteins in 3-month-old, partially pancreatectomized (PPx) mice. However, β-cell proliferation is known to become severely restricted with advanced age. Therefore, it is unknown whether mangiferin is able to reverse the diabetic condition and retain β-cell regeneration capability in aged mice. In the present study, 12-month-old C57BL/6J mice that had undergone PPx were subjected to mangiferin treatment (90 mg/kg) for 28 days. Mangiferin-treated aged mice exhibited decreased blood glucose levels and increased glucose tolerance, which was accompanied with higher serum insulin levels when compared with those in untreated PPx control mice. In addition, islet hyperplasia, elevated β-cell proliferation and reduced β-cell apoptosis were also identified in the mice that received mangiferin treatment. Further studies on the mRNA transcript and protein expression levels indicated comparatively increased levels of cyclins D1 and D2 and cyclin-dependent kinase 4 in mangiferin-treated mice, while the levels of p27Kip1 and p16INK4a were decreased relative to those in the untreated PPx controls. Of note, mangiferin treatment improved the proliferation rate of islet β-cells in adult mice overexpressing p16INK4a, suggesting that mangiferin induced β-cell proliferation via the regulation of p16INK4a. In addition, the mRNA transcription levels of critical genes associated with insulin secretion, including pancreatic and duodenal homeobox 1, glucose transporter 2 and glucokinase, were observed to be upregulated after mangiferin treatment. Taken together, it was indicated that mangiferin treatment significantly induced β-cell proliferation and inhibited β-cell apoptosis by regulating cell cycle checkpoint proteins. Furthermore, mangiferin was also demonstrated to regulate genes associated with insulin secretion. Collectively these, results suggest the therapeutic potential of mangiferin in the treatment of diabetes in aged individuals.

Abstract
The present study aimed to explore the renoprotective effect of metformin on diabetic nephropathy in type 2 diabetic rats. A rat model of type 2 diabetic nephropathy (T2DN) was successfully induced via a high-fat diet combined with a single low-dose of streptozotocin. Metformin was administered intragastrically for 13 weeks, and fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), HDL-c, LDL-c, urinary and serum creatinine levels were subsequently examined at the end of administration. Renal function was determined after the treatment protocol. Expression levels of transforming growth factor (TGF)-β1 and connective tissue growth factor (CTGF) were assessed via immunohistochemical analysis. Superoxide dismutase activity, malondialdehyde content and glutathione peroxidase levels were assessed in kidney tissues using commercially available kits. The results of the present study demonstrated that metformin administration significantly decreased the levels of serum blood urea nitrogen, serum creatinine, creatinine clearance, urinary albumin excretion and fasting blood glucose in rats with T2DN. Furthermore, TG, TC and LDL-c levels were significantly decreased following metformin treatment, whereas HDL-c was increased. Metformin treatment significantly increased SOD activity and significantly decreased malondialdehyde levels, as compared with the model group. It was also demonstrated that metformin administration significantly decreased the expression levels of TGF-β1 and attenuated the morphological changes associated with T2DN in rats. These data clearly demonstrated the renoprotective effects of metformin against the development and progression of T2DN in rats. The underlying mechanism of this protective effect may be associated with glycemic control, lipid metabolism, and anti-oxidative and anti-inflammatory functions.

Abstract
The current review article is an attempt to explain the therapeutic potential of mangiferin, a bioactive compound of the mango, against lifestyle-related disorders. Mangiferin (2-β-D-glucopyranosyl-1,3,6,7-tetrahydroxy-9H-xanthen-9-one) can be isolated from higher plants as well as the mango fruit and their byproducts (i.e. peel, seed, and kernel). It possesses several health endorsing properties such as antioxidant, antimicrobial, antidiabetic, antiallergic, anticancer, hypocholesterolemic, and immunomodulatory. It suppresses the activation of peroxisome proliferator activated receptor isoforms by changing the transcription process. Mangiferin protects against different human cancers, including lung, colon, breast, and neuronal cancers, through the suppression of tumor necrosis factor α expression, inducible nitric oxide synthase potential, and proliferation and induction of apoptosis. It also protects against neural and breast cancers by suppressing the expression of matrix metalloproteinase (MMP)-9 and MMP-7 and inhibiting enzymatic activity, metastatic potential, and activation of the β-catenin pathway. It has the capacity to block lipid peroxidation, in order to provide a shielding effect against physiological threats. Additionally, mangiferin enhances the capacity of the monocyte-macrophage system and possesses antibacterial activity against gram-positive and gram-negative bacteria. This review summarizes the literature pertaining to mangiferin and its associated health claims.

Abstract
PURPOSE Mangiferin is a naturally occurring glucosylxanthone with beneficial effects on glucose and lipid homeostasis. This study investigates the potential therapeutic effect of Mangiferin in perivascular adipose tissue (PVAT) and whether it contributes to regulating insulin action in the endothelium. METHODS Palmitate challenge evoked ROS-associated endoplasmic reticulum stress (ER stress) and NLRP3 inflammasome activation in PVAT. The conditioned medium from PA-stimulated PVAT was prepared to induce endothelial insulin resistance, and improved endothelium-dependent vasodilation in response to insulin was detected in vitro and in vivo. RESULTS Mangiferin treatment enhanced LKB1-dependent AMPK activity and suppressed ER stress with downregulation of TXNIP induction, leading to the inhibition of NLRP3 inflammasome activation evidenced by attenuated NLRP3 and cleaved caspase-1 expression as well as reduced IL-1β secretion. Moreover, Mangiferin restored insulin-mediated Akt and eNOS phosphorylations with increased NO production, immunohistochemistry examination of adipocytes, and endothelial tissue in high-fat diet-fed mice also showed that oral administration of Mangiferin inhibited ER stress and NLRP3 induction in PVAT, and then effectively prevented insulin resistance in the vessel endothelium. CONCLUSIONS Taken together, these results revealed that Mangiferin suppressed ER stress-associated NLRP3 inflammasome activation in PVAT through regulation of AMPK activity, which prevented endothelial insulin resistance. These findings suggested that the amelioration of PVAT dysfunction may be a therapeutic strategy for the prevention of endothelial insulin resistance.

Abstract
BACKGROUND Studies in animal models have shown that allicin, a major biologically active component of garlic, can play a role in the prevention of tissue fibrosis in the liver, lung and heart, mainly related to the inhibition of fibroblast proliferation, fibrogenic cytokine secretion and extracellular matrix synthesis. This study aimed to investigate the protective effects of allicin on renal damage in streptozotocin (STZ)-induced diabetic rats. STZ-induced diabetic rats were administered allicin (15, 30 and 45 mg · kg-1 · day-1 ) via daily intra-gastric gavage for 12 weeks. The levels of fasting blood glucose (FBG), blood urea nitrogen (BUN), serum creatinine (sCr), lipid and 24 h urine albumin excretion (UAE) were measured at the end of weeks 4, 8 and 12. The renal histopathology and the expression levels of collagen I, transforming growth factor β1 (TGF-β1) and phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2) were measured using immunohistochemistry and/or western blotting. RESULTS In 12 week STZ-induced diabetic rats, severe hyperglycemia and albuminuria were markedly developed. Treatment with allicin for 12 weeks ameliorated diabetes-induced morphological alterations of the kidney and decreased FBG, BUN, sCr, triglyceride (TG) and 24 h UAE in diabetic rats. The expression levels of collagen I, TGF-β1 and p-ERK1/2 were significantly decreased by allicin treatment. CONCLUSION These results suggested that allicin may play a protective role in diabetic nephropathy via the TGF-β1/ERK pathway in diabetic rats. © 2016 Society of Chemical Industry.

Abstract
Aphloia theiformis (Vahl.) Benn. (AT) is traditionally used in Sub-Saharan African countries including Mauritius as a biomedicine for the management of several diseases. However, there is a dearth of experimental studies to validate these claims. We endeavoured to evaluate the inhibitory effects of crude aqueous extract as traditionally used together with the crude methanol extracts of AT leaves on urease, angiotensin (I) converting enzyme (ACE), acetylcholinesterase (AChE), cholesterol esterase (CEase), glycogen phosphorylase a (GPa), and glycation in vitro. The crude extract showing potent activity against the studied enzymes was further partitioned using different solvents of increasing polarity. The enzyme inhibitory and antiglycation activities of each fraction was assessed. Kinetic of inhibition of the active crude extract/fractions on the aforementioned enzymes was consequently determined using Lineweaver-Burk plots. An ultra-high performance liquid chromatography (UHPLC-UV/MS) system was used to establish the phytochemical profile of AT. The real time cell analysis system (iCELLigence™) was used to monitor any cellular cytotoxicity of AT. Crude methanolextract (CME) was a potent inhibitor of the studied enzymes, with IC50 ranging from 696.22 to 19.73μg/mL. CME (82.5%) significantly (p<0.05) inhibited glycation and was comparable to aminoguanidine (81.5%). Ethyl acetate and n-butanol fractions of CME showed non-competitive, competitive, and uncompetitive mode of inhibition against ACE, CEase, and AChE respectively. Mangiferin, a xanthone glucoside was present in CME, ethyl acetate, and n-butanol fractions. Active extract/fractions were found to be non-cytotoxic (IC50>20μg/mL) according to the U.S National Cancer Institute plant screening program. This study has established baseline data that tend to justify the traditional use of AT and open new avenues for future biomedicine development.

Abstract
Over the last era, small molecules sourced from different plants have gained attention for their varied and long-term medicinal benefits. Their advantageous therapeutic effects in diverse pathological complications lead researchers to give an ever-increasing emphasis on them and discover their novel therapeutic potentials. Among these, the heat stable, xanthonoid group of organic molecules has gained special importance with distinctive regards to the bioactive molecule mangiferin due to its solubility in water. Mangiferin, a yellow polyphenol having C-glycosyl xanthone structure, is widely present in different edible sources like mango, and possesses numerous biological activities. Extensive research with this molecule shows its antioxidant, anti-inflammatory, antidiabetic, anticancer, antimicrobial, analgesic, and immunomodulatory properties. Thus, it provides protection against a wide range of physiological disorders. The C-glucosyl linkage and polyhydroxy groups in mangiferin's structure contribute essentially to its free radical-scavenging activity. Moreover, its ability in regulating various transcription factors like NF-κB, Nrf-2, etc. and modulating the expression of different proinflammatory signaling intermediates like tumor necrosis factor-α, COX-2, etc. contribute to its anti-inflammatory, anticancer, and antidiabetic potentials. In this comprehensive article, information has been provided about the sources, chemical structure, metabolism, and different biological activities of mangiferin with special emphasis on the underlying cellular signal transduction pathways. Insights into an in-depth assessment of mangiferin's anti-inflammatory therapeutic potential have also been discussed in detail. On an overall perspective, this review aims to stage mangiferin's diversified therapeutic applications and its emerging possibility as a promising drug in future based on its anti-inflammatory property. © 2016 BioFactors, 42(5):459-474, 2016.

Mangiferin Upregulates Glyoxalase 1 Through Activation of Nrf2/ARE Signaling in Central Neurons Cultured with High Glucose. Mol Neurobiol 2016; 54:4060-4070.

Abstract
Mangiferin, a natural C-glucoside xanthone, has anti-inflammatory, anti-oxidative, neuroprotective actions. Our previous study showed that mangiferin could attenuate diabetes-associated cognitive impairment of rats by enhancing the function of glyoxalase 1 (Glo-1) in brain. The aim of this study was to investigate whether Glo-1 upregulation by mangiferin in central neurons exposed to chronic high glucose may be related to activation of Nrf2/ARE pathway. Compared with normal glucose (25 mmol/L) culture, Glo-1 protein, mRNA, and activity levels were markedly decreased in primary hippocampal and cerebral cortical neurons cultured with high glucose (50 mmol/L) for 72 h, accompanied by the declined Nrf2 nuclear translocation and protein expression of Nrf2 in cell nucleus, as well as protein expression and mRNA level of γ-glutamylcysteine synthetase (γ-GCS) and superoxide dismutase activity, target genes of Nrf2/ARE signaling. Nonetheless, high glucose cotreating with mangiferin or sulforaphane, a typical inducer of Nrf2 activation, attenuated the above changes in both central neurons. In addition, mangiferin and sulforaphane significantly prevented the formation of advanced glycation end-products (AGEs) reflecting Glo-1 activity, while elevated the level of glutathione, a cofactor of Glo-1 activity and production of γ-GCS, in high glucose cultured central neurons. These findings demonstrated that Glo-1 was greatly downregulated in central neurons exposed to chronic high glucose, which is expected to lead the formation of AGEs and oxidative stress damages. We also proved that mangiferin enhanced the function of Glo-1 under high glucose condition by inducing activation of Nrf2/ARE signaling pathway.

Abstract
Polyphenols have been described to have a wide range of biological activities, and many reports, published during recent years, have highlighted the beneficial effects of phenolic compounds, illustrating their promising role as therapeutic tools in several acute and chronic disorders. The purpose of study was to evaluate, in an already-assessed model of lung injury caused by bleomycin (BLM) administration, the role of resveratrol and quercetin, as well as to explore the potential beneficial properties of a mango leaf extract, rich in mangiferin, and a grape leaf extract, rich in dihydroquercetin (DHQ), on the same model. Mice were subjected to intra-tracheal administration of BLM, and polyphenols were administered by oral route immediately after BLM instillation and daily for 7 d. Treatment with resveratrol, mangiferin, quercetin and DHQ inhibited oedema formation and body weight loss, as well as ameliorated polymorphonuclear infiltration into the lung tissue and reduced the number of inflammatory cells in bronchoalveolar lavage fluid. Moreover, polyphenols suppressed inducible nitric oxide synthase expression, and prevented oxidative and nitroxidative lung injury, as shown by the reduced nitrotyrosine and poly (ADP-ribose) polymerase levels. The degree of apoptosis, as evaluated by Bid and Bcl-2 balance, was also suppressed after polyphenol treatment. Finally, these natural products down-regulated cyclo-oxygenase-2, extracellular signal-regulated kinase phosphorylated expression and reduced NF-κBp65 translocation. Our findings confirmed the anti-inflammatory effects of resveratrol and quercetin in BLM-induced lung damage, and highlight, for the first time, the protective properties of exogenous administration of mangiferin and DHQ on experimental pulmonary fibrosis.

Abstract
The mangiferin-berberine (MB) salt was synthesized by ionic bonding of mangiferin (M) and berberine (B) at an equal molecular ratio. This study aimed to investigate the activities of MB salt in modulating lipid and glucose metabolisms in HepG2 cells. After 24 h treatment of the studying compounds, cellular AMP-activated protein kinase α (AMPKα)/acetyl-CoA carboxylase (ACC) protein levels and carnitine palmitoyltransferase (CPT) 1 activities, intracellular lipid contents, mRNA expression levels of target genes, glucose consumption, and glucose production amounts were determined. Compound C (CC) was used in the blocking experiments. Our results showed that MB salt increased p-AMPKα (Thr172)/p-ACC (Ser79) levels and CPT1 activity and suppressed oleic acid- (OA-) induced lipid accumulation and upregulation of lipogenic genes potently in HepG2 cells. The above activities of MB salt were AMPK dependent and were superior to those of M or B when administered at an equal molar concentration. MB salt enhanced basal and insulin-stimulated glucose consumption and suppressed gluconeogenesis more potently than M or B alone. The inhibiting activity of MB salt on cellular gluconeogenesis was AMPK dependent. Our results may support MB salt as a new kind of agent for the development of novel lipid or glucose-lowering drugs in the future.

Abstract
A rapid, selective and sensitive UPLC-MS/MS assay was established to determine the plasma concentrations of four steroidal saponins. Sprague-Dawley rats were allocated to four groups which were orally administered Anemarrhena asphodeloides extracts (ASE), ASE combined with macromolecular fraction (ASE-MF), ASE combined with small molecule fraction (ASE-SF) and ASE combined with small molecule and macromolecular fraction (ASE-SF-MF) containing approximately the same dose of ASE. At different time points, the concentration of timosaponin BII, anemarsaponin BIII, timosaponin AIII and timosaponin E1 in rat plasma were determined and main pharmacokinetic parameters including Cmax, Tmax, T1/2, AUC were calculated using the DAS 3.2 software package. The statistical analysis was performed using the Student's t-test with p < 0.05 as the level of significance. MF had no effect on the pharmacokinetic behaviors and parameters of four steroidal saponins. It was found that Cmax and AUC of four steroidal saponins in group ASE-SF and ASE-SF-MF, were significantly increased compared with those in group ASE. These results indicate that SF in A. asphodeloides extracts could increase the absorption and improve the bioavailability of the steroidal saponins.

Abstract
Diabetes mellitus is a major health concern, affecting nearly 10% of the population. Here we describe a potential novel therapeutic agent for this disease, X-3, a derivative of mangiferin. Therapeutic administration of X-3 significantly and dose-dependently reduced plasma glucose and triglycerides in db/db mice following 8 week-treatments. Treatment with X-3 dose-dependently increased the number of insulin-positive β-cell mass. Importantly, X-3 did not cause any death or signs of toxicity in acute toxicity studies. Study of mechanism of action revealed that X-3 increased glucose uptake in parallel with increased phosphorylation of AMP-activated protein kinase (AMPK) in 3T3-L1 cells. It activates AMPK in both LKB1-dependent and -independent manner. Furthermore, administration of X-3 resulted in activation of AMPK and its downstream target, acetyl-CoA carboxylase (ACC) in the hypothalamus, liver, muscle and adipose tissues of C57BL/6 mice. An 80 mg/kg X-3 was more potent than metformin at 500 mg/kg in the hypothalamus, and interscapular fat tissues, potent than MF at the same dose in the liver. Thus, we conclude that X-3 is a promising new class of AMPK activating drug, and can potentially be used in the treatment of type 2 diabetes.

Abstract
The incidence of diabetes mellitus continue to rise annually all over the world with India and Nigeria having recorded cases of 65.1 and 3.9 million respectively in 2013 and expected to increase by a large amount in 2035. Hyperglycemia is a pre-condition for the development of diabetic complications and is accompanied by an increase in the production of free radicals. The present available treatment option for diabetes like sulfonylurea, metformin and alpha-glucosidase are restricted by their limited actions, secondary failure rates, and side-effects; and unaffordable to the majority of the population. Hence, the need to screen for more medicinal plants with antidiabetic ability due to the fact that plants are; biodegradable, safe and cheap with fewer side-effects. In this review article, we have presented the current status of diabetes in India and Nigeria and the role of some less commonly used medicinal plants from both countries that have antidiabetic potential.

[PMID: 25380391 DOI: 10.1002/ptr.5254] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2014] [Revised: 09/25/2014] [Accepted: 10/10/2014] [Indexed: 12/24/2022]
Abstract
This study was designed to investigate the effects of mangiferin on renal fibrosis, osteopontin production, and inflammation in the kidney of diabetic rats. Diabetes was induced through the single administration of streptozotocin (55 mg/kg, i.p.). Diabetic rats were treated with mangiferin (15, 30, and 60 mg/kg/day, i.g.) for 9 weeks. The kidney was fixed in 10% formalin for glomerulus fibrosis examination using Masson trichrome staining. Kidney and blood were obtained for assays of the associated biochemical parameters. Chronic mangiferin treatment prevented renal glomerulus fibrosis evidenced by decreases in Mason-stained positive area of glomeruli, protein expression of type IV collagen, and α-smooth muscle actin in the kidney of diabetic rats, in comparison with decreases in mRNA and protein expression of osteopontin as well as protein expression of cyclooxygenase 2 and NF-кB p65 subunit in the renal cortex of diabetic rats. Moreover, mangiferin reduced the levels of interleukin 1β in both the serum and the kidney of diabetic rats. Our findings demonstrate that mangiferin prevents the renal glomerulus fibrosis of diabetic rats, which is realized through the suppression of osteopontin overproduction and inflammation likely via inactivation of NF-кB.

Mangiferin attenuates diabetic nephropathy by inhibiting oxidative stress mediated signaling cascade, TNFα related and mitochondrial dependent apoptotic pathways in streptozotocin-induced diabetic rats. PLoS One 2014; 9:e107220. [PMID: 25233093 PMCID: PMC4169432 DOI: 10.1371/journal.pone.0107220] [Citation(s) in RCA: 130] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2014] [Accepted: 08/14/2014] [Indexed: 12/31/2022] Open
Abstract
Oxidative stress plays a crucial role in the progression of diabetic nephropathy in hyperglycemic conditions. It has already been reported that mangiferin, a natural C-glucosyl xanthone and polyhydroxy polyphenol compound protects kidneys from diabetic nephropathy. However, little is known about the mechanism of its beneficial action in this pathophysiology. The present study, therefore, examines the detailed mechanism of the beneficial action of mangiferin on STZ-induced diabetic nephropathy in Wister rats as the working model. A significant increase in plasma glucose level, kidney to body weight ratio, glomerular hypertrophy and hydropic changes as well as enhanced nephrotoxicity related markers (BUN, plasma creatinine, uric acid and urinary albumin) were observed in the experimental animals. Furthermore, increased oxidative stress related parameters, increased ROS production and decreased the intracellular antioxidant defenses were detected in the kidney. Studies on the oxidative stress mediated signaling cascades in diabetic nephropathy demonstrated that PKC isoforms (PKCα, PKCβ and PKCε), MAPKs (p38, JNK and ERK1/2), transcription factor (NF-κB) and TGF-β1 pathways were involved in this pathophysiology. Besides, TNFα was released in this hyperglycemic condition, which in turn activated caspase 8, cleaved Bid to tBid and finally the mitochorndia-dependent apoptotic pathway. In addition, oxidative stress also disturbed the proapoptotic-antiapoptotic (Bax and Bcl-2) balance and activated mitochorndia-dependent apoptosis via caspase 9, caspase 3 and PARP cleavage. Mangiferin treatment, post to hyperglycemia, successfully inhibited all of these changes and protected the cells from apoptotic death.

Abstract
Sericin from discarded silkworm cocoons of silk reeling has been used in different fields, such as cosmetology, skin care, nutrition, and oncology. The present study established a rat model of type 2 diabetes by consecutive intraperitoneal injections of low-dose (25 mg/kg) streptozotocin. After intragastrical perfusion of sericin for 35 days, blood glucose levels significantly declined, and the expression of neurofilament protein in the sciatic nerve and nerve growth factor in L4-6 spinal ganglion and anterior horn cells significantly increased. However, the expression of neuropeptide Y in spinal ganglion and anterior horn cells significantly decreased in model rats. These findings indicate that sericin protected the sciatic nerve and related nerve cells against injury in a rat type 2 diabetic model by upregulating the expression of neurofilament protein in the sciatic nerve and nerve growth factor in spinal ganglion and anterior horn cells, and downregulating the expression of neuropeptide Y in spinal ganglion and anterior horn cells.

Abstract
Mangiferin is a major bioactive ingredient in Mangifera indica Linn. (Anacardiaceae) leaves. Aqueous extract of such leaves have been used as an indigenous remedy for respiratory diseases like asthma and coughing in traditional Chinese medicine. However, underlying molecular mechanisms of mangiferin on anti-asthma remain unclear. In our present study, we investigated the anti-asthmatic effect of mangiferin on Th1/Th2 cytokine profiles and explored its underlying immunoregulatory mechanism in mouse model of allergic asthma. Mangiferin significantly reduced the total inflammatory cell counts and eosinophil infiltration, decreased the production of ovalbumin-specific IgE in serum and PGD2 in BALF. The antibody array analysis showed that mangiferin down-regulated the levels of one group of cytokines/chemokines including Th2-related IL-4, IL-5, IL-13, and others IL-3, IL-9, IL-17, RANTES, TNF-α, but simultaneously up-regulated Th1-related IFN-γ, IL-2 and IL-10 and IL-12 expression in serum. Thus it attenuates the imbalance of Th1/Th2 cells ratio by diminishing the abnormal mRNA levels of Th1 cytokines (IFN-γ and IL-12) and Th2 cytokines (IL-4, IL-5 and IL-13). Finally, mangiferin substantially inhibited the activation and expression of STAT-6 and GATA-3 in excised lung tissues. Our results suggest that mangiferin can exert anti-asthmatic effect. The underlying mechanism may attribute to the modulation of Th1/Th2 cytokine imbalance via inhibiting the STAT6 signaling pathway.

JOURNAL OF ETHNOPHARMACOLOGY 2014; 153:42-60. [PMID: 24556224 DOI: 10.1016/j.jep.2014.02.013] [Citation(s) in RCA: 114] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2013] [Revised: 02/09/2014] [Accepted: 02/09/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anemarrhena asphodeloides Bunge. (Asparagaceae) yields Anemarrhenae Rhizoma, which has a long history to be used as a traditional medicine to treat various ailments, like cold-induced febrile disease with arthralgia, hematochezia, tidal fever and night sweats by Yin deficiency, bone-steaming, cough, and hemoptysis. It is also used as an ingredient of healthy food, wine, tea, biological toothpaste. Its importance is demonstrated by large scale to treat kinds of diseases in eastern Asian countries. The aim of this review is to provide up-to-date information about phytochemistry, pharmacology, and toxicology of Anemarrhena asphodeloides based on scientific literatures. It will build up a new foundation for further study on mechanism and development of better therapeutic agent and healthy product from Anemarrhena asphodeloides. MATERIAL AND METHODS All the available information on Anemarrhena asphodeloides was collected via electronic search (using PubMed, SciFinder Scholar, CNKI, TPL (www.theplantlist.org), Google Scholar, Baidu Scholar, and Web of Science). RESULTS Comprehensive analysis of the literatures searched through sources available above confirmed that the ethnomedical uses of Anemarrhena asphodeloides had been recorded in China, Japan, and Korea for thousands of years. The phytochemical investigation revealed the presence of steroidal saponins, flavonoids, phenylpropanoids, alkaloids, steroids, organic acids, anthraquinones, and others. Crude extracts and pure compounds from Anemarrhena asphodeloides exhibited significant pharmacological effects on the nervous system and the blood system. They also showed valuable bioactivities, such as antitumor, anti-oxidation, anti-microbial, anti-virus, anti-inflammation, anti-osteoporosis, anti-skin aging and damage as well as other activities. CONCLUSIONS In light of long traditional use and modern phytochemical and pharmacological studies summarized, Anemarrhena asphodeloides has demonstrated a strong potential for therapeutic and health-maintaining purposes. Both the extracts and chemical components isolated from the plant showed a wide range of biological activities. Thus more pharmacological mechanisms on main active compounds (TBII, TAIII, mangiferin and other ingredients) are necessary to be explored. In addition, as a good source of the traditional medicine, clinical studies of main therapeutic aspects (e.g. diabetes, Alzheimer׳s disease, Parkinson׳s disease, etc.), toxicity and adverse effect of Anemarrhena asphodeloides will also undoubtedly be the focus of future investigation.

Abstract
Cardiorenal syndrome (CRS) is a complex disease in which the heart and kidney are simultaneously affected and their deleterious declining functions are reinforced in a feedback cycle, with an accelerated progression. Although the coexistence of kidney and heart failure in the same individual carries an extremely bad prognosis, the exact cause of deterioration and the pathophysiological mechanisms underlying the initiation and maintenance of the interaction are complex, multifactorial in nature, and poorly understood. Current therapy includes diuretics, natriuretic hormones, aquaretics (arginine vasopressin antagonists), vasodilators, and inotropes. However, large numbers of patients still develop intractable disease. Moreover, the development of resistance to many standard therapies, such as diuretics and inotropes, has led to an increasing movement toward utilization and development of novel therapies. Herbal and traditional natural medicines may complement or provide an alternative to prevent or delay the progression of CRS. This review provides an analysis of the possible mechanisms and the therapeutic potential of phytotherapeutic medicines for the amelioration of the progression of CRS.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Long term hyperglycemia leads to development of complications associated with diabetes. Diabetic complications are now a global health problem without effective therapeutic approach. Hyperglycemia and oxidative stress are important components for the development of diabetic complications. Over the past few decades, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of diabetic complications due to their multiple targets and less toxic side effects. This review aims to assess the current available knowledge of medicinal herbs for attenuation and management of diabetic complications and their underlying mechanisms. MATERIAL AND METHODS Bibliographic investigation was carried out by scrutinizing classical text books and peer reviewed papers, consulting worldwide accepted scientific databases (SCOPUS, PUBMED, SCIELO, NISCAIR, Google Scholar) to retrieve available published literature. The inclusion criteria for the selection of plants were based upon all medicinal herbs and their active compounds with attributed potentials in relieving diabetic complications. Moreover, plants which have potential effect in ameliorating oxidative stress in diabetic animals have been included. RESULTS Overall, 238 articles were reviewed for plant literature and out of the reviewed literature, 127 articles were selected for the study. Various medicinal plants/plant extracts containing flavonoids, alkaloids, phenolic compounds, terpenoids, saponins and phytosterol type chemical constituents were found to be effective in the management of diabetic complications. This effect might be attributed to amelioration of persistent hyperglycemia, oxidative stress and modulation of various metabolic pathways involved in the pathogenesis of diabetic complications. CONCLUSION Screening chemical candidate from herbal medicine might be a promising approach for new drug discovery to treat the diabetic complications. There is still a dire need to explore the mechanism of action of various plant extracts and their toxicity profile and to determine their role in therapy of diabetic complications. Moreover, a perfect rodent model which completely mimics human diabetic complications should be developed.

Abstract
RATIONALE Evidences indicate that methylglyoxal, a highly reactive metabolite of hyperglycemia, can enhance protein glycation, oxidative stress, or inflammation. Mangiferin, a polyphenol compound of C-glucoside, has many beneficial biological activities, including anti-inflammation, anti-oxidation, neuroprotection, cognitive enhancement, etc. Whether mangiferin alleviates diabetes-associated cognitive impairment is still unclear. OBJECTIVES The present study was designed to investigate the effects of mangiferin on the behavioral deficits of diabetic rats induced by streptozotocin; the mechanisms associated with methylglyoxal toxicity are especially investigated. METHODS Diabetic rats were treated with mangiferin (15, 30, and 60 mg/kg, p.o.) for 9 weeks. Cognitive performances were evaluated with the Morris water maze. Hippocampus and blood were obtained for evaluation of the effects of mangiferin on protein glycation, oxidative stress, and inflammation in diabetic state. RESULTS Mangiferin significantly improved the behavioral performances of diabetic rats, evidenced by a decrease in escape latency as well as increases in numbers of crossing the platform and percentage of time spent in the target quadrant, which were accompanied by decreases in the levels of advanced glycation end-products and their receptor (RAGE), interleukin-1β, TNF-α, and malondialdehyde and increases in the activity and expression of glyoxalase 1 as well as glutathione level in the hippocampus of diabetic rats. Furthermore, mangiferin produced a significant decrease in malondialdehyde level and increased glutathione level and superoxide dismutase activity in the serum of diabetic rats. CONCLUSIONS This study demonstrates that mangiferin can markedly ameliorate diabetes-associated cognitive decline in rats, which is done likely through suppressing methylglyoxal hyperactivity (promoting protein glycation, oxidative stress, and inflammation) mediated noxious effects.

Anti-inflammatory effects of mangiferin on sepsis-induced lung injury in mice via up-regulation of heme oxygenase-1. J Nutr Biochem 2012; 24:1173-81.

Abstract
Sepsis, a serious unbalanced hyperinflammatory condition, is a tremendous burden for healthcare systems, with a high mortality and limited treatment. Increasing evidences indicated that some active components derived from natural foods have potent anti-inflammatory properties. Here we show that mangiferin (MF), a natural glucosyl xanthone found in both mango and papaya, attenuates cecal ligation and puncture-induced mortality and acute lung injury (ALI), as indicated by reduced systemic and pulmonary inflammatory responses. Moreover, pretreatment with MF inhibits sepsis-activated mitogen-activated protein kinases and nuclear factor kappa-light-chain-enhancer of activated B cells signaling, resulting in inhibiting production of proinflammatory mediators. Notably, MF dose-dependently up-regulates the expression and activity of heme oxygenase (HO)-1 in the lung of septic mice. Further, these beneficial effects of MF on the septic lung injury were eliminated by ZnPP IX, a specific HO-1 inhibitor. Our results suggest that MF attenuates sepsis by up-regulation of HO-1 that protects against sepsis-induced ALI through inhibiting inflammatory signaling and proinflammatory mediators. Thereby, MF may be effective in treating sepsis with ALI.

Abstract
Diabetic ophthalmopathy (DO) impairs patients' eyesight and even causes blindness. Here, we investigated the effect of 60% ethanol extract of the rhizome of Anemarrhenae asphodeloides (ERA), which is commonly used in Chinese medicine formulae in treating diabetes, on DO progression. Blood glucose, insulin, advanced glycation end products (AGE), super oxygen dehydrogenises (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) levels in serum and sorbitol concentration in the lens were measured. Retinal endothelium/pericyte (E/P) ratio was evaluated, and structural changes of the retina and lens were observed. Effects of mangiferin and neomangiferin, the two major components of ERA, on subnormal growth of pericytes induced by high glucose were also detected. It was found that the activities of SOD and GSH-Px in serum were increased, whereas MDA and AGE levels in serum and sorbitol concentration in the lens were decreased in ERA-treated DO rats. E/P ratio was decreased, and the pathological changes of the lens and retina were alleviated by ERA treatment. Moreover, the subnormal growth of pericytes induced by high glucose was ameliorated by mangiferin and neomangiferin. These results indicated that ERA could effectively prevent DO progression in streptozotocin-induced diabetic rats, and mangiferin and neomangiferin may be the main effective components.

Abstract
BACKGROUND Taiwan has the highest incidence of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide. Chinese herbal medicine (CHM) has been linked to CKD/ESRD in Taiwan. The specific effects and frequency of CHM on the risk of CKD are unknown. METHODS A hospital-based case-control study was performed from August 2006 through December 2009. The cases were consecutive nephrology outpatients 20years of age or older, with a first-time diagnosis of CKD, and without cancer or pre-existing renal disease. The controls were randomly selected outpatients that did not have CKD and were matched 1:1 to cases for age, gender and date of outpatient visit. RESULTS Four hundred and twenty-four patients were recruited. Among 212 cases, 23.6% took non-prescribed CHM, compared to 6.6% among the controls (p<0.001). Multivariate analysis showed that illiteracy [odds ratio (OR) 6.3, 95% confidence interval (CI) 2.4-16.6], hypertension (OR 5.4, 95% CI 2.9-9.8) and occasional use of non-prescribed CHM (OR 6.2, 95% CI 1.8-21.6) were positively associated with CKD, whereas regular exercise was inversely associated with CKD (OR 0.5, 95% CI 0.3-0.9). CONCLUSION Occasional use of non-prescribed CHM was associated with the risk of CKD in Taiwan.
