Abstract
Diabetes is linked with various microvascular and macrovascular complications. Nephropathy, neuropathy and retinopathy are important microvascular complications of diabetes. Different types of secondary metabolites including glycosides have been studied for their effects in diabetic complications. Various glycosides such as flavanoid glycosides and saponin glycosides are reported for their beneficial effects in diabetic nephropathy, neuropathy, retinopathy and cardiomyopathy by action on various pathways involved in the progression of these complications. Coumarin glycosides and cryanogenic glycosides have been studied for their effective role in diabetic nephropathy. Phenolic glycosides and anthraquinone glycosides also have beneficial role in diabetic neuropathy. The present review focuses on various classes of glycosides and their role in the prevention and treatment of vascular complications of diabetes.

Ramakrishnan P, Loh WM, Gopinath SC, Bonam SR, Fareez IM, Mac Guad R, Sim MS, Wu YS. Selective phytochemicals targeting pancreatic stellate cells as new anti-fibrotic agents for chronic pancreatitis and pancreatic cancer. Acta Pharm Sin B 2020; 10:399-413. [PMID: 32140388 PMCID: PMC7049637 DOI: 10.1016/j.apsb.2019.11.008] [Citation(s) in RCA: 52] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2019] [Revised: 09/23/2019] [Accepted: 10/29/2019] [Indexed: 12/15/2022] Open
Abstract
Activated pancreatic stellate cells (PSCs) have been widely accepted as a key precursor of excessive pancreatic fibrosis, which is a crucial hallmark of chronic pancreatitis (CP) and its formidable associated disease, pancreatic cancer (PC). Hence, anti-fibrotic therapy has been identified as a novel therapeutic strategy for treating CP and PC by targeting PSCs. Most of the anti-fibrotic agents have been limited to phase I/II clinical trials involving vitamin analogs, which are abundant in medicinal plants and have proved to be promising for clinical application. The use of phytomedicines, as new anti-fibrotic agents, has been applied to a variety of complementary and alternative approaches. The aim of this review was to present a focused update on the selective new potential anti-fibrotic agents, including curcumin, resveratrol, rhein, emodin, green tea catechin derivatives, metformin, eruberin A, and ellagic acid, in combating PSC in CP and PC models. It aimed to describe the mechanism(s) of the phytochemicals used, either alone or in combination, and the associated molecular targets. Most of them were tested in PC models with similar mechanism of actions, and curcumin was tested intensively. Future research may explore the issues of bioavailability, drug design, and nano-formulation, in order to achieve successful clinical outcomes with promising activity and tolerability.

Abstract
Ferns are an important phytogenetic bridge between lower and higher plants. Historically they have been used in many ways by humans, including as ornamental plants, domestic utensils, foods, and in handicrafts. In addition, they have found uses as medicinal herbs. Ferns produce a wide array of secondary metabolites endowed with different bioactivities that could potentially be useful in the treatment of many diseases. However, there is currently relatively little information in the literature on the phytochemicals present in ferns and their pharmacological applications, and the most recent review of the literature on the occurrence, chemotaxonomy and physiological activity of fern secondary metabolites was published over 20 years ago, by Soeder (Bot Rev 51:442-536, 1985). Here, we provide an updated review of this field, covering recent findings concerning the bioactive phytochemicals and pharmacology of fern species.

Abstract
Qing Ye Dan (QYD) is the whole plant of Swertia mileensis and used in Chinese folk medicine for the treatment of prostatitis, benign prostatic hyperplasia (BPH) and so on. This study was to investigate the effects of QYD and its main component swertiamarin on BPH induced by testosterone in rats. The prostatic expressions of vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), basic fibroblast growth factor (βFGF) and proliferating cell nuclear antigen (PCNA) were detected by immunohistochemistry assay. Prostatic levels of oxidative stress and inflammatory-related factors were also analyzed. Additionally, the prostatic expressions of androgen receptor (AR), estrogen receptor (ER)-α, ER-β, hypoxia-inducible factor (HIF)-1α, B-cell CLL/lymphoma (Bcl)-2 and Bcl-2-associated X protein (Bax) were measured by western blot. The epithelial-mesenchymal transition (EMT) associated factors were evaluated by quantitative RT-PCR. It showed that QYD and swertiamarin ameliorated the testosterone-induced prostatic hyperplasia and collagen deposition, attenuated the over-expressions of HIF-1α, VEGF, EGF, βFGF, PCNA, AR and ER-α, reduced the ratio of Bcl-2/Bax, enhanced the expression of ER-β, inhibited the oxidative stress and local inflammation, as well as relieved prostatic EMT. It suggested that QYD and swertiamarin had prostatic protective potential against BPH.

Abstract
Critical polytrauma patients present a series of pathophysiological disturbances, biochemical and molecular dysfunction, which comprise to be the major cause of intensive care unit admission. In regard to molecular damage, there exists a series of factors, which all together contribute to the aggravation of the clinical status leading to increased mortality rate in these patients. One of the most important biochemical factors involved is the nuclear transcription factor B (NF-κB). Impaired NF-κB functioning is reflected on the clinical status of the patient through increased production of pro-inflammatory molecule, leading to multiple organ dysfunction syndrome. In addition to this, through microRNAs interactions, various pathophysiological as well as biochemical disturbances are produced, which altogether further reduce the patient's survival rate. In this paper, we would like to present the modifications seen in the expression of NF-κB in critically polytraumatized patients with sepsis. In additions to this, we would like to discuss the correlation between the microRNAs and its further implications in clinical status of these patients.

Abstract
Herbal products have been used as conventional medicines for thousands of years, particularly in Eastern countries. Thousands of clinical and experimental investigations have focused on the effects and mechanisms-of-action of herbal medicine in the treatment of cardiovascular diseases (CVDs). Considering the history of clinical practice and the great potentials of herb medicine and/or its ingredients, a review on this topic would be helpful. This article discusses possible effects of herbal remedies in the prevention and treatment of CVDs. Crucially, we also summarize some underlying pharmacological mechanisms for herb products in cardiovascular regulations, which might provide interesting information for further understanding the effects of herbal medicines, and boost the prospect of new herbal products against CVDs.

Abstract
Sechium edule is traditionally used in Mexico as a therapeutic resource against renal diseases and to control high blood pressure. The purpose of this work is to evaluate the antihypertensive effect of the hydroalcoholic extract obtained from the roots of this plant, including its fractions and subfractions, on different hypertension models induced with angiotensin II (AG II). The hydroalcoholic extract was tested on an in vitro study of isolated aorta rings denuded of endothelial cells, using AG II as the agonist; this assay proved the vasorelaxant effect of this extract. Vagotomized rats were administered different doses of AG II as well as the Hydroalcoholic extract, which reduced blood pressure in 30 mmHg approximately; subsequently this extract was separated into two fractions (acetone and methanol) which were evaluated in the acute hypertension mouse model induced with AG II, where the acetone fraction was identified as the most effective one and was subsequently subfractioned using an open chromatographic column packed with silica gel. The subfractions were also evaluated in the acute hypertension model. Finally, the extract, fraction, and active subfraction were analyzed by MS-PDA-HPLC, identifying cinnamic derivative compounds like cinnamic acid methyl ester.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abacopteris penangiana (Hook.) Ching (AP) is traditionally used in Chinese medicine to promote blood circulation, remove blood stasis and dampness and for the treatment of edema and inflammation. In order to further support and develop the traditional use of Abacopteris penangiana as Chinese folk medicine, the aim of this study is to investigate the protective effect of the total flavanol glycosides (TFA) from AP and its acid hydrolysate (AHT) on chronic non-bacterial prostatitis (CNP) by measuring the levels of oxidative stress and inflammatory responses in rats. MATERIALS AND METHODS First, the antioxidant and anti-inflammatory activities of AHT and TFA were investigated. Then the experimental chronic non-bacterial prostatitis was induced by carrageenan. The prostate index (PI) and prostate specific antigen (PSA) were determined. The activities of AHT and TFA on inhibiting free radicals and oxidative stress were investigated. Subsequently, the degree of chronic inflammatory cell infiltrates, acinar changes and interstitial fibrosis were evaluated by histopathological examination. In addition, the relative inflammatory factors, tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β), cyclooxygenase-2 (COX-2), prostaglandin E2 (PEG2), transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF) were measured. Finally, the prostatic expression of nuclear transcription factor-κB (NF-κB) was determined by immunohistochemistry and western blot analysis. RESULTS The whole results showed that AHT and TFA had strong antioxidant and anti-inflammatory activities. In CNP model, AHT and TFA successfully decreased PI and PSA. The activities of antioxidant enzymes in AHT or TFA group were enhanced. Additionally, a morphometric analysis of the prostate gland of AHT or TFA treated rats demonstrated a significant reduction in chronic inflammatory cell infiltrates and interstitial fibrosis compared to model group. The reduced values of TNF-α, IL-1β, COX-2, PEG2, inducible nitric oxide synthase (iNOS) and nitric oxide (NO) were observed both in AHT and TFA treated groups. Moreover, the levels of TGF-β1 and CTGF in AHT and TFA treated groups were significantly decreased along with the alleviation of the inflammatory state of the prostate gland. Besides, the prostatic expression of NF-κB was inhibited. CONCLUSIONS These results suggest that AHT and TFA have anti-prostatitis properties via inhibiting oxidative stress, NF-κB dependent pro-inflammatory cytokines, fibrosis-related factors and antinociceptive activity. Hence, AP represents a potential herb for the treatment of prostatitis.

Abstract
The therapeutic effect of pterosin A, a small-molecular-weight natural product, on diabetes was investigated. Pterosin A, administered orally for 4 weeks, effectively improved hyperglycemia and glucose intolerance in streptozotocin, high-fat diet-fed, and db/db diabetic mice. There were no adverse effects in normal or diabetic mice treated with pterosin A for 4 weeks. Pterosin A significantly reversed the increased serum insulin and insulin resistance (IR) in dexamethasone-IR mice and in db/db mice. Pterosin A significantly reversed the reduced muscle GLUT-4 translocation and the increased liver phosphoenolpyruvate carboxyl kinase (PEPCK) expression in diabetic mice. Pterosin A also significantly reversed the decreased phosphorylations of AMP-activated protein kinase (AMPK) and Akt in muscles of diabetic mice. The decreased AMPK phosphorylation and increased p38 phosphorylation in livers of db/db mice were effectively reversed by pterosin A. Pterosin A enhanced glucose uptake and AMPK phosphorylation in cultured human muscle cells. In cultured liver cells, pterosin A inhibited inducer-enhanced PEPCK expression, triggered the phosphorylations of AMPK, acetyl CoA carboxylase, and glycogen synthase kinase-3, decreased glycogen synthase phosphorylation, and increased the intracellular glycogen level. These findings indicate that pterosin A may be a potential therapeutic option for diabetes.

Abstract
Background Atherosclerosis is one of the major complications of type 2 diabetic patients (T2DM), leading to morbidity and mortality. Grape seed procyanidin B2 (GSPB2) has demonstrated protective effect against atherosclerosis, which is believed to be, at least in part, a result of its antioxidative effects. The aim of this study is to identify the target protein of GSPB2 responsible for the protective effect against atherosclerosis in patients with DM. Methods and Results GSPB2 (30 mg/kg body weight/day) were administrated to db/db mice for 10 weeks. Proteomics of the aorta extracts by iTRAQ analysis was obtained from db/db mice. The results showed that expression of 557 proteins were either up- or down-regulated in the aorta of diabetic mice. Among those proteins, 139 proteins were normalized by GSPB2 to the levels comparable to those in control mice. Among the proteins regulated by GSPB2, the milk fat globule epidermal growth factor-8 (MFG-E8) was found to be increased in serum level in T2DM patients; the serum level of MFG-E8 was positively correlated with carotid-femoral pulse wave velocity (CF-PWV). Inhibition of MFG-E8 by RNA interference significantly suppressed whereas exogenous recombinant MFG-E8 administration exacerbated atherogenesis the db/db mice. To gain more insights into the mechanism of action of MFG-E8, we investigated the effects of MFG-E8 on the signal pathway involving the extracellular signal-regulated kinase (ERK) and monocyte chemoattractant protein-1 (MCP-1). Treatment with recombinant MFG-E8 led to increased whereas inhibition of MFG-E8 to decreased expression of MCP-1 and phosphorylation of ERK1/2. Conclusion Our data suggests that MFG-E8 plays an important role in atherogenesis in diabetes through both ERK and MCP-1 signaling pathways. GSPB2, a well-studied antioxidant, significantly inhibited the arterial wall changes favoring atherogenesis in db/db mice by down-regulating MFG-E8 expression in aorta and its serum level. Measuring MFG-E8 serum level could be a useful clinical surrogate prognosticating atherogenesis in DM patients.
