Food Sci Nutr 2023; 11:7626-7637. [PMID: 38107145 PMCID: PMC10724611 DOI: 10.1002/fsn3.3682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 08/25/2023] [Accepted: 08/30/2023] [Indexed: 12/19/2023] Open
Abstract
The antidiabetic activity of saponins extracted from Momordica charantia (MCS) on streptozotocin-induced diabetic mice was investigated in order to elucidate the mechanism of MCS for exerting hypoglycemic effects. Saponins were first extracted from M. charantia L. and their composition was analyzed. The diabetic Kunming mice were fed low-dose saponins from M. charantia L. and high-dose MCS, using normal mice and diabetic mice as controls. Body weight, blood glucose level, oral glucose tolerance, serum C-peptide level, hepatic antioxidant capacity, hepatic glycogen and hexokinase in liver tissues, serum blood lipid level, and alpha-glucosidase activity in small intestines were measured, and microstructure of pancreatic islet was analyzed. The results showed that the total content of seven triterpenoid compounds in MCS was 18.24 μg/mg, with Momordicoside K having the highest content at 11.66 μg/mg. Diabetic mice treated with MCS at 100 and 200 mg/kg body weight daily for 30 days showed a maximum glucose reduction (p < .05) of 12.63% and 26.47%, respectively. MCS significantly decreased levels of postprandial hyperglycemia, serum lipid, α-glucosidase activity, and liver malondialdehyde. Additionally, levels of serum C-peptide and liver glycogen, as well as hexokinase and antioxidant enzyme activity, were significantly increased compared to the diabetic control groups. Histopathological results showed that MCS markedly reduced degenerative changes in islet β-cells. It is concluded that MCS exerts antidiabetic effects by improved hypoglycemic, hypolipidemic, and antioxidant effects, increased hexokinase activity and glycogen synthesis, and enhanced reparative effects on the histological architecture and insulin secretion function of the pancreas.

Abstract
α-Amylase is a generally acknowledged molecular target of a distinct class of antidiabetic drugs named α-glucosidase inhibitors. This class of medications is scarce and rather underutilized, and treatment with current commercial drugs is accompanied by unpleasant adverse effects. However, mammalian α-amylase inhibitors are abundant in nature and form an extensive pool of high-affinity ligands that are available for drug discovery. Individual compounds and natural extracts and preparations are promising therapeutic agents for conditions associated with impaired starch metabolism, e.g., diabetes mellitus, obesity, and other metabolic disorders. This review focuses on the structural diversity and action mechanisms of active natural products with inhibitory activity toward mammalian α-amylases, and emphasizes proteinaceous inhibitors as more effective compounds with significant potential for clinical use.

Abstract
Amyloid β protein (Aβ) is the main component of neuritic plaques in Alzheimer's disease (AD), and its accumulation has been considered as the molecular driver of Alzheimer's pathogenesis and progression. Aβ has been the prime target for the development of AD therapy. However, the repeated failures of Aβ-targeted clinical trials have cast considerable doubt on the amyloid cascade hypothesis and whether the development of Alzheimer's drug has followed the correct course. However, the recent successes of Aβ targeted trials have assuaged those doubts. In this review, we discussed the evolution of the amyloid cascade hypothesis over the last 30 years and summarized its application in Alzheimer's diagnosis and modification. In particular, we extensively discussed the pitfalls, promises and important unanswered questions regarding the current anti-Aβ therapy, as well as strategies for further study and development of more feasible Aβ-targeted approaches in the optimization of AD prevention and treatment.

Natural products as novel anti-obesity agents: insights into mechanisms of action and potential for therapeutic management. Front Pharmacol 2023; 14:1182937. [PMID: 37408757 PMCID: PMC10318930 DOI: 10.3389/fphar.2023.1182937] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 06/06/2023] [Indexed: 07/07/2023] Open
Abstract
Obesity affects more than 10% of the adult population globally. Despite the introduction of diverse medications aimed at combating fat accumulation and obesity, a significant number of these pharmaceutical interventions are linked to substantial occurrences of severe adverse events, occasionally leading to their withdrawal from the market. Natural products serve as attractive sources for anti-obesity agents as many of them can alter the host metabolic processes and maintain glucose homeostasis via metabolic and thermogenic stimulation, appetite regulation, pancreatic lipase and amylase inhibition, insulin sensitivity enhancing, adipogenesis inhibition and adipocyte apoptosis induction. In this review, we shed light on the biological processes that control energy balance and thermogenesis as well as metabolic pathways in white adipose tissue browning, we also highlight the anti-obesity potential of natural products with their mechanism of action. Based on previous findings, the crucial proteins and molecular pathways involved in adipose tissue browning and lipolysis induction are uncoupling protein-1, PR domain containing 16, and peroxisome proliferator-activated receptor-γ in addition to Sirtuin-1 and AMP-activated protein kinase pathway. Given that some phytochemicals can also lower proinflammatory substances like TNF-α, IL-6, and IL-1 secreted from adipose tissue and change the production of adipokines like leptin and adiponectin, which are important regulators of body weight, natural products represent a treasure trove for anti-obesity agents. In conclusion, conducting comprehensive research on natural products holds the potential to accelerate the development of an improved obesity management strategy characterized by heightened efficacy and reduced incidence of side effects.

Radix Rehmanniae Praeparata (Shu Dihuang) exerts neuroprotective effects on ICV-STZ-induced Alzheimer's disease mice through modulation of INSR/IRS-1/AKT/GSK-3β signaling pathway and intestinal microbiota. Front Pharmacol 2023; 14:1115387. [PMID: 36843923 PMCID: PMC9945319 DOI: 10.3389/fphar.2023.1115387] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 01/27/2023] [Indexed: 02/10/2023] Open
Abstract
Radix Rehmanniae Praeparata (RRP, Shu Dihuang in Cinese) is widely used as primal medicine in Chinese herbal formula for the treatment of Alzheimer's disease (AD). However, the underlying mechanism of RRP for AD remains unclear. The aim of this study was to investigate the therapeutic effect of RRP on intracerebroventricular injection of streptozotocin (ICV-STZ)-induced AD model mice and its potential mechanism. ICV-STZ mice were continuously gavaged with RRP for 21 days. The pharmacological effects of RRP were evaluated by behavioral tests, brain tissue H&E staining and hippocampal tau protein phosphorylation levels. The expression levels of insulin receptor (INSR), IRS-1, pSer473-AKT/AKT and pSer9-GSK-3β/GSK-3β proteins in hippocampal and cortical tissues were detected by Western-blot method. The 16S rRNA gene sequencing was used to analyze the changes of intestinal microbiota in mice. The compounds in RRP were analyzed by mass spectrometry and their binding ability to INSR proteins was detected by molecular docking. The results showed that RRP ameliorated cognitive dysfunction and neuronal pathological changes of brain tissue in ICV-STZ mice, reduced tau protein hyperphosphorylation, INSR, IRS-1, pSer473-AKT/AKT, and pSer9-GSK-3β/GSK-3β levels in hippocampal and cortical tissues. Meanwhile, RRP reversed ICV-STZ-induced dysregulation of intestinal microbiota in AD mice. Mass spectrometry analysis showed that the RRP consisted mainly of seven compounds, namely Acteoside (Verbascoside), 5-Hydroxymethyl-2-furaldehyde (5-HMF), Apigenin7-O-glucuronide, Icariin, Gallic acid, Quercetin-3β-D-glucoside, and Geniposide. Molecular docking results further indicated that the compounds in RRP have binding ability to INSR protein and potential multiple synergistic effects. RRP ameliorates cognitive dysfunction and brain histopathological changes in AD mice. The mechanism of RRP ameliorating AD may be related to the regulation of INSR/IRS-1/AKT/GSK-3β signaling pathway and intestinal microbiota. This study supports the potential anti-AD efficacy of RRP and initially reveals the pharmacological mechanism of RRP, providing a theoretical basis for further clinical application of RRP.

PLoS One 2022; 17:e0278536. [PMID: 36455062 PMCID: PMC9714931 DOI: 10.1371/journal.pone.0278536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 11/18/2022] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Poria cocos (Schw.) Wolf or Fuling is one of the top 10 most frequently prescribed herbs in China for the treatment of type 2 diabetes mellitus (T2DM). OBJECTIVE The purpose of this systematic review is to determine the additional benefit of Fuling formulae use in addition to hypoglycaemic agents for T2DM in randomised clinical trials. METHODS English (5) and Chinese (4) medical databases were searched from their inception to August 2021. RCTs that included Fuling in herbal formulae for T2DM were included. Risk of bias were assessed using the Cochrane Collaboration's procedures. Stata software (13.0) was used for data analysis. RESULTS Seventy-three RCTs (6,489 participants) with herbal formulae containing Fuling were included. Most studies were at risk of bias and strength of the evidence were low to moderate. Meta-analysis findings showed that the addition of formulae containing Fuling to hypoglycaemic agent-treatments could benefit people with T2DM by reducing fasting blood glucose (MD -0.82 [-0.93, -0.71]; I2 = 79.6%, P = 0.00), 2-hour postprandial blood glucose (MD-1.15 [-1.31, -0.98], I2 = 80%, P = 0.00) and haemoglobin A1c (MD-0.64 [-0.75, -0.53], I2 = 84.7%, P = 0.00). Adverse events were also significantly lower in the integrative group than in the hypoglycaemic alone group (RR 0.99 [0.93, 1.06], P = 0.87). CONCLUSION Evidence from this study supports the use of Fuling formulae combined with hypoglycaemic agents for T2DM. The combined therapies appear to be well tolerated. TRAIL REGISTRATION This review is registered with the PROSPERO international prospective register of systematic reviews (CRD42020214635).

Antidiabetic Activity of Mung Bean or Vigna radiata (L.) Wilczek Seeds in Alloxan-Induced Diabetic Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6990263. [PMID: 36337582 PMCID: PMC9629934 DOI: 10.1155/2022/6990263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/01/2022] [Accepted: 10/17/2022] [Indexed: 11/07/2022]
Abstract
Introduction Despite the development of oral hypoglycemic medications, diabetes and its associated complications continue to be significant clinical issues. The purpose of this study was to examine the antidiabetic effects of Vigna radiata (L.) Wilczek seeds in mice that had been given alloxan to cause diabetes. Methods In Swiss albino mice, diabetes was brought on by a single intraperitoneal injection of the drug alloxan (150 mg/kg). For 14 days, glibenclamide (5 mg/kg) and methanol extract of V. radiata seeds (100, 200, and 400 mg/kg) were given orally. Following oral administration of V. radiata to mice, the blood glucose levels (BGL) and body weight were measured at 7 and 14 days. The mice were sacrificed at the end of the trial, and blood samples were taken for the evaluation of insulin, glycated hemoglobin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), high-density lipoprotein (HDL), total cholesterol (TC), and triglyceride (TG) levels. It was determined how much glycogen was present in the liver. Additionally, the total phenolic and flavonoid contents of V. radiata were determined, along with the in vitro DPPH (2, 2 diphenyl-1-picrylhrazyl) free radical-scavenging activity. P < 0.05 was chosen as the cutoff for statistical significance. Results Following oral administration of V. radiata for 14 days, diabetic mice's BGL and bad cholesterol (TC and TG) levels significantly decreased, while HDL levels increased. Treatment with V. radiata significantly decreased the levels of AST, ALT, and glycated hemoglobin when compared with diabetes control. On the other hand, it raised insulin levels and the amount of liver glycogen. V. radiata underwent phytochemical analysis, which identified the presence of tannins, saponins, phenols, alkaloids, terpenoids, steroids, flavonoids, and glycosides. Per gram of V. radiata seed extract, the total phenolic content was 43.12 ± 3.14 mg of gallic acid equivalents, while the total flavonoid content was 38.35 ± 2.6 mg of quercetin equivalents. Ascorbic acid was shown to have an IC50 value of 18.64 µg/ml during a DPPH-scavenging assay, while V. radiata had an IC50 value of 73.35 µg/ml. Conclusion According to the findings of the current study, the methanolic extract of the seeds from the plant V. radiata possesses significant antidiabetic characteristics that are on par with those of the commonly used drug glibenclamide. Hence, V. radiata seems to be effective as a natural antidiabetic.

Abstract
Objective Nigella sativa (N. sativa) from the family Ranunculaceae has medicinal properties. Previous studies have reported promising findings showing that N. sativa may benefit cardiometabolic health; however, current evidence on its cardiometabolic effects on those with prediabetes and type 2 diabetes mellitus (T2DM) is still unclear. Hence, we conducted a systematic review and meta-analysis to assess the efficacy of N. sativa on cardiometabolic parameters in population with prediabetes and T2DM. Methods PubMed/Medline, ISI Web of Science, Scopus, and Cochrane library were systematically searched up to June 20, 2022. Meta-analyses using random-effects models were used. Results Eleven randomized controlled trials (RCTs) were included in the meta-analysis. N. sativa intervention resulted in significant changes in fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), c-reactive protein (CRP), and malondialdehyde (MDA), without overall changes in glucose levels after oral glucose tolerance test (OGTT), fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), triglyceride, high-density lipoprotein cholesterol (HDL-C), and body mass index (BMI) when compared with the control group. In subgroup analyses, N. sativa supplementation enhanced serum levels of HDL-C in subjects with baseline HDL-C lower than 40 mg/dL. Furthermore, HOMA-IR and BMI values decreased in the N. sativa-supplemented group compared with the control group, when the length of follow-up was more than 8 weeks and the dose was more than 1 g/day for N. sativa supplementation, respectively. Conclusion Our findings indicate that N. sativa supplementation may effectively improve cardiometabolic profiles in individuals with prediabetes and T2DM.

Astragalus polysaccharides (APS) has shown a significant therapeutic effect on type 2 diabetes mellitus (T2DM), but its mechanism needs to be further clarified. T2DM rat model was induced by intraperitoneal streptozotocin injection and treated with APS for 8 weeks. Daily indicators of experimental rats were observed, and expression levels of STRs and genes related to glycolipid metabolism were determined by real-time quantitative PCR and western blot. The present study revealed that APS alleviated the symptoms of T2DM rats, improved HOMA-IR and promoted insulin secretion. Gene expression analysis found that APS significantly increased the expressions of signaling molecules in STRs pathways, including taste receptor family 1 member 2 (T1R2), α-gustducin (Gα) and transient receptor potential cation channel subfamily member 5 (TRPM5), and reversed the expressions of genes related to glucolipid metabolism, including glucose transporters 2 and 4 (GLUT2 and GLUT4), pyruvate carboxylase (PC), fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC) in the liver of T2DM rats. However, APS had no influences on the expressions of genes, including glycogen synthase kinase-3 beta (GSK-3β), pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK) in the liver of T2DM rats. These results suggested that the physiological roles of STRs in the liver were involved with glucose transport and metabolism. APS alleviated T2DM rats by activating the STRs pathway, and promoted glucose transport and lipogenesis.

Abstract
Diabetes mellitus is one of the most prevalent metabolic disorders that affect people of all genders, ages, and races. Medicinal herbs have gained attention from researchers and have been widely investigated for their antidiabetic potential. Saffron (Crocus sativus L.) and its main constituents, that is, crocin and crocetin, are natural carotenoid compounds, widely known to possess a wide spectrum of properties and induce pleiotropic anti-inflammatory, anti-oxidative, and neuro-protective effects. An increasing number of experimental, animal and human studies have investigated the effects and mechanism of action of these compounds and their potential therapeutic use in the treatment of diabetes. This narrative review presents the key findings of published clinical studies that examined the effects of saffron and/or its constituents in the context of diabetes mellitus. Moreover, an overview of the proposed underlying mechanisms mediating these effects, the medicinal applications of saffron, and the new findings regarding its effect on diabetes and various cellular and molecular mechanisms of action will be debated.

Abstract
:
The increased prevalence of obesity, metabolic syndrome and type 2 diabetes has
prompted scientists to look for new active and safe molecules that may help the prevention of metabolic
disorders: hyperglycemia, insulin-resistance and dyslipidemia. Berberine is an alkaloid
compound derived from plants, and it is largely used in traditional Chinese medicine. The aim of
this study is to investigate in SCOPUS and Web of Science (WOS) databases how the scientists
focused on the use of berberine against metabolic disorders, in human subjects. We carried A bibliometric
analysis of scientific literature and performed 2 searches: 1) “Berberine” AND “Diabetes”
AND “Diabetes Type 2”, 2) “Berberine” AND “Metabolic Syndrome”, both in ARTICLE
(Title/Abstract/Keyword) with a time limitation of 1st January, 2000 through 31st December,
2018, with the filter on “HUMAN” AND/OR “HUMANS”. The research sorted out 500 papers,
finding about 300 (60 %) in the first search definition and 200 (40 %) in the second. The refined
research sorted out 46 papers regarding the use of berberine in diabetes, and 40 articles on the use
of the alkaloid compound in metabolic syndrome. For both topics, we found increasing interest
between 2008 and 2009, with citation trends in a constant crescendo in the overall period studied.
These findings underlined that berberine is a safe and interesting botanical compound, especially
against chronic-metabolic disorder that affects billions of people globally, and emphasized that
scientists are interested in searching for long-term therapies that show no major adverse effects.

Adansonia digitata L. (Baobab Fruit) Effect on Postprandial Glycemia in Healthy Adults: A Randomized Controlled Trial. Nutrients 2022; 14:nu14020398. [PMID: 35057579 PMCID: PMC8778021 DOI: 10.3390/nu14020398] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/06/2022] [Accepted: 01/13/2022] [Indexed: 02/01/2023] Open
Abstract
Baobab fruits have been traditionally used in Africa due to their therapeutic properties attributed to their high polyphenol content. The aim of the study was to investigate the effect of baobab fruit on postprandial glycaemia in healthy adults and to measure its bioactive compounds and antioxidant activity. The study (NCT05140629) was conducted on 31 healthy subjects. The participants were randomly allocated in the control group (oral glucose tolerance test (OGTT); n = 16) and in the intervention group (OGTT, followed by administration of 250 mL baobab aqueous extract (BAE); n = 15). Total phenols, proanthocyanins, hydrolyzable tannins, and antioxidant activity (FRAP, DPPH, ABTS, and inhibition of O2•− and NO• methods) were quantified. Repeated measures ANOVA of mixed type and independent samples t-test were used. Glycemia incremental area under the curve (p = 0.012) and glucose maximum concentration (p = 0.029) was significantly lower in the intervention group compared to the control group. The BAE revealed high total contents of phenols, proanthocyanins, and hydrolyzable tannins, as well as a strong capacity to scavenge superoxide anions and nitric oxide radicals and a high antioxidant activity. In conclusion, this study encourages the use of this food component as a promising source of natural antioxidants and a hypoglycemic agent under glucose load acute conditions.

Gegen Qinlian Decoction ameliorates type 2 diabetes osteoporosis via IGFBP3/MAPK/NFATc1 signaling pathway based on cytokine antibody array. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 94:153810. [PMID: 34798519 DOI: 10.1016/j.phymed.2021.153810] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 10/09/2021] [Accepted: 10/17/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Osteoporosis affects more than half the patients with type 2 diabetes mellitus (T2DM). Up to data, there is no effective clinical practice in managing type 2 diabetes osteoporosis (T2DOP) because of its complex pathogenesis. Gegen Qinlian Decoction (GQD) has been used for the long-term management of T2DM. However, the underlying mechanism of GQD in the treatment of T2DOP remains unknown. PURPOSE To reveal the role of GQD in T2DOP and its potential therapeutic targets in the management of T2DOP. STUDY DESIGN The effect of GQD on T2DOP was observed in db/db mice in four groups: model group, GQD low-dose group (GQD-L), GQD high-dose group (GQD-H), and metformin (positive control) group. C57BL/6J mice were used as the negative control group. METHODS Quantitative phytochemical analysis of GQD was performed using high-performance liquid chromatography (HPLC). Micro-CT and hematoxylin-eosin (H&E) staining were used to evaluate bone histomorphometry. To screen for candidate targets of GQD, a cytokine antibody array was used, followed by bioinformatics analysis. Quantitative real-time PCR (qRT-PCR) and western blotting (WB) were used to determine expression levels. RESULTS The major active components of GQD were confirmed by HPLC. Micro-CT and H&E staining showed that bone mass was significantly increased in the GQD-H group compared with the model group. Antibody arrays revealed that the expression of insulin-like growth factor binding protein 3 (IGFBP3) was elevated in the GQD-H group. The MAPK pathway was identified using bioinformatics analysis. Additionally, the levels of osteoclastogenesis-related genes, including cathepsin K (Ctsk), acid phosphatase 5 (Acp5), matrix metallopeptidase 9 (Mmp9), and ATPase H+ transporting V0 subunit D2 (Atp6v0d2) were significantly decreased in the GQD-H group. Compared with the model group, high-dosage GQD inhibited phosphorylation of extracellular signal-regulated kinases (ERKs) and P38 mitogen-activated protein kinase (MAPK) and the expression of c-Fos and nuclear factor of activated T cells 1 (NFATc1). CONCLUSION GQD plays a protective role in T2DOP by upregulating IGFBP3 expression and downregulating the IGFBP3/MAPK/NFATc1 signaling pathway. IGFBP3 in serum may also be a novel biomarker in the treatment of T2DOP. Our current findings not only expand the application of GQD, but also provide a theoretical basis and guidance for T2DOP.

Abstract
Objective To establish the diagnosis model for syndromes of type 2 diabetes mellitus (T2-DM) and explore symptoms, the pulse and tongue signs, and laboratory indexes related to syndromes of T2-DM. Methods A syndromatologic and laboratory investigation was conducted in 554 T2-DM patients with 58 symptoms, 14 tongue signs, 6 pulse signs, and 12 laboratory indexes. The clinical data on the syndrome were collected and analyzed by using logistic regression analysis, decision tree, and K-nearest neighbor to establish a diagnostic model for effectively distinguishing the typical syndromes in T2-DM patients. Results The most typical syndromes revealed in T2-DM were stomach heat flourishing (SHF) syndrome (261 patients, accounting for 47.1%) and Qi-Yin deficiency (QYD) syndrome (293 patients, 52.9%). According to the clinical data of the patients with these two syndromes, variables including 6 symptoms and signs, 2 pulse signs, 1 tongue sign, and 2 laboratory indicators were introduced into the logistic regression model. All of them were statistically significant. Then, a diagnostic model constructed by QUEST and CHAID algorithms of the decision tree for identifying the two syndromes was proved to have an accurate diagnostic rate of 85.2%. It was found that the following sign and symptoms were effective to differentiate these two syndromes: odor in the mouth, polyphagia, vulnerability to starvation, burning sensation in the stomach, fatigue, limb weakness, slippery and replete pulse, weak pulse, pink tongue, oral glucose tolerance test, and hemoglobin A1C. A classification model constructed by the K-nearest neighbor method to identify the two syndromes showed an accurate diagnostic rate of 88.3%. Three major statistically significant predictors included in the model were slippery and replete pulse, polyphagia, and weak pulse (P < 0.05). Conclusion A model for distinguishing the two typical syndromes (SHF syndrome and QYD syndrome) in T2-DM patients was effectively established. This model could help to provide methodological support for the standardization of traditional Chinese medicine (TCM) syndrome differentiation methods.

Abstract
Objective To explore the mechanism of modified Huanglian Maidong decoction (Maidong-Sanqi-Huanglian Compounds, MSHCs) intervention in type 2 diabetes mellitus (T2DM). Method This study used PubChem and SciFinder to collect the molecular structure of MSHCs, used PharmMapper to predict the potential targets of MSHC, and combined them with the T2DM gene to construct MSHC-T2DM protein-protein interaction (PPI) network. The plugin MCODE in Cytoscape 3.7.1 was then used to perform cluster analysis on the MSHC-T2DM PPI network. The genes and targets were input into DAVID for Gene Ontology (GO) and pathway enrichment analysis. Finally, animal experiments were performed to verify the therapeutic effect of MSHC on T2DM. Results Several T2DM-related targets, clusters, signaling pathways, and biological processes are found. The experimental results showed that compared with the blank group, the content of fasting blood glucose (FBG) in the model group was higher (P < 0.01). Compared with the model group, the content of FBG decreased and the insulin level increased in the MSHC medium-dose (0.15 g/kg) and high-dose (0.45 g/kg) groups and metformin group after 4 weeks of drug administration (P < 0.05). MSHC can also improve blood liquid levels and inflammatory factor levels (P < 0.05). Conclusion MSHC may achieve therapeutic effects through regulating the T2DM-related targets, biological processes, and pathways, such as insulin resistance, energy metabolism, oxidative stress, and inflammation, found in this research.

Abstract
PURPOSE Although the cost and complexity of managing diabetes is increasing around the world, placing greater burden on patients and their families, the cost of drug regimens prescribed to Chinese patients has not been evaluated. This study was conducted to evaluate the temporal changes in the costs and drugs used for people with diabetes. METHODS Patients enrolled in Beijing Medical Insurance with outpatient medical records from 2016 through 2018 were included in this study. The outcomes of interest were: (1) the number of outpatient medications, (2) the number of comorbidities diagnosed, (3) the estimated annual cost of the outpatient drug regimen, (4) the drug therapy strategies used for diabetic patients, and (5) the most commonly prescribed classes of drugs. RESULTS Over the 3-year period, there was a significant decrease (9.0%, P <.001) in the average number of diabetes medications used. Both antiglycemic and non-antiglycemic drug use decreased by 3.6% and 12.9%, respectively. Similarly, for estimated annual costs of medication, an 18.4% (P <.05) decrease was observed, with a gradual decreased from ¥6,868 ($1,059) in 2016 to ¥5,605 ($865) in 2018. CONCLUSION This is the first large-scale cost analysis of the medical management of diabetes since the implementation of medical insurance in China. Despite the increasing availability of newer, more expensive diabetes drugs, there was a significant reduction in the number of diabetes medications used, that may be due to a more rational approach to optimizing metabolic targets.

Abstract
The effects of garlic oil (GO) on serum fatty acids, lipid profiles and energy-related blood metabolites in feed-restricted fat-tailed ewes were investigated. For this purpose, twenty-eight dry, non-pregnant Makuei ewes (about three years of age; 45.00 ± 2.20 kg of body weight) were assigned randomly to four experimental groups including group 1 receiving basal diet as total mixed ration (TMR) without GO supplementation (control group), group 2 receiving 100% basal diet supplemented with GO (10.00 mg kg-1 BW), group 3 receiving 70.00% basal diet without GO supplementation and group 4 receiving 70.00% basal diet supplemented with GO (10.00 mg kg-1 BW). The main experimental period started eight weeks after performing adaptation and dietary allocations. Feed restriction reduced serum glucose levels along with higher serum levels of non-esterified fatty acids, triacylglycerols, β-hydroxybutyrate, low-density lipoprotein cholesterol, total cholesterol and very low-density of lipoprotein. Following feed restriction, the serum palmitic and oleic acids concentrations were increased. Garlic oil supplementation had a desirable effect on feed-restricted animals through lowering serum BHB and palmitic and oleic acids concentration and increasing the high-density lipoprotein cholesterol levels in the serum. These findings demonstrated that GO had the potential to reduce body-fat mobilization, thereby lowering the risk factors for disorders associated with negative energy balance in underfed ewes in the periparturient period.

Efficiency and Safety of Chinese Herbal Medicine in the Treatment of Prediabetes: A Systemic Review and Meta-Analysis of Randomized Controlled Trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:3628036. [PMID: 33123206 PMCID: PMC7584953 DOI: 10.1155/2020/3628036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/21/2020] [Accepted: 09/11/2020] [Indexed: 11/17/2022]
Abstract
Objective The aim of this study was to review existing evidence on the efficiency and safety of Chinese herbal medicine for the treatment of prediabetes. Methods Randomized controlled trials (RCTs) of Chinese herbal medicine (CHM) to treat prediabetes were searched in the following databases from their inception date onwards until 2 May 2020: MEDLINE, Cochrane, EMBASE, Web of Science, EBSCO, CINAHL, CNKI, VIP database, CBM, and Wanfang database. Quality assessment of included trials was accessed according to the guidance in Cochrane. Researchers independently assessed the validity of included trials and extracted outcome data for synthesis. RevMan 5.3 was used for the meta-analysis. Results Twenty-two RCTs including 3923 participants were included in the study. Our findings upon the 22 RCTs showed CHM is effective in the treatment of prediabetes, which can statistically reduce the incidence of diabetes (RR = 0.48; 95% CI = (0.41, 0.57); P < 0.001), increase the incidence of normalization of prediabetes (RR = 1.76; 95% CI = (1.57, 1.96); P < 0.001), and lower FPG (MD = −0.38; 95% CI = (−0.60, −0.16); P < 0.001), 2hPG (MD = −1.13; 95% CI = (−1.60, −0.67); P < 0.001), TG (MD = −0.23; 95% CI = (−0.33, −0.13); P < 0.001), TC (MD = −0.34; 95% CI = (−0.52, −0.16); P < 0.001), and BMI (MD = −0.48; 95% CI = (−0.78, −0.18); P < 0.001) after treatment, and there was no difference of HbA1c (P > 0.05). Conclusion CHM is effective for the treatment of prediabetes. CHM can statistically reduce the incidence of diabetes, increase the incidence of normalization of prediabetes, and lower the FPG, 2hPG, TG, TC, and BMI levels, but with no significant difference in HbA1c. In addition, CHM was relatively safe in clinical practice. More high-quality RCTs should be conducted to strengthen the finding.

PLoS One 2020; 15:e0240616. [PMID: 33035272 PMCID: PMC7546448 DOI: 10.1371/journal.pone.0240616] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 09/29/2020] [Indexed: 02/06/2023] Open
Abstract
Alisma orientale (Sam.) Juzep (A. orientale) is a traditional herb that is often used to treat disease including edema and hyperlipidemia. However, the molecular mechanism by which Alisma orientale (Sam.) Juzep exerts its hypolipidemic effects remains unclear. In this study, a diabetic rat model was established by feeding a high-fat and high-sugar diet combined with a low-dose streptozotocin injection (HFS). Then the rats were treated with an A. orientale water extract (AOW), an A. orientale ethanolic extract (AOE) or metform (MET). The gut microflora and liver transcriptome were analyzed by high-throughput next-generation sequencing. Ultra-performance liquid chromatography-triple quadrupole-mass spectrometry was employed to analyze the major compounds in the AOE. The results showed that the serum total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels in rats of the AOE group (2.10 g/kg/day, 14 days) were significantly lower than those in the HFS group (p<0.01). Moreover, AOE treatment altered the gut microecology, particularly modulating the relative abundance of gut microflora involved in lipid metabolism compared with the HFS group. Furthermore, compared with the HFS group, the mRNA expression levels of Fam13a, Mapk7, Mpp7, Chac1, Insig1, Mcpt10, Noct, Greb1l, Fabp12 and Hba-a3 were upregulated after the administration of AOE. In contrast, the mRNA expression levels of Lox, Mybl1, Arrdc3, Cyp4a2, Krt20, Vxn, Ggt1, Nr1d1 and S100a9 were downregulated. Moreover, AOE treatment for two weeks markedly promoted the relative abundance of Lachnospiraceae (p = 0.0013). The triterpenoids contents in AOE were alisol A, alisol A 24-acetate, alisol B, alisol B 23-acetate, alisol C 23-acetate, alisol F, alisol F 24-acetate, and alisol G. Our findings above illustrated that the hypolipidemic effect of the triterpenoids of A. orientale is mediated mainly through alteration of the gut microecology and the regulation of genes involved in cholesterol metabolism, especially Insig1.

Silk Fibroin Promotes the Regeneration of Pancreatic β-Cells in the C57BL/KsJ- Leprdb/db Mouse. Molecules 2020; 25:molecules25143259. [PMID: 32708887 PMCID: PMC7397053 DOI: 10.3390/molecules25143259] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 07/07/2020] [Accepted: 07/15/2020] [Indexed: 12/19/2022] Open
Abstract
Diabetes mellitus is a chronic metabolic disease, and its progression leads to serious complications. Although various novel therapeutic approaches for diabetes mellitus have developed in the last three decades, its prevalence has been rising more rapidly worldwide. Silk-related materials have been used as anti-diabetic remedies in Oriental medicine and many studies have shown the effects of silk fibroin (SF) in both in vitro and in vivo models. In our previous works, we reported that hydrolyzed SF improved the survival of HIT-T15 cells under high glucose conditions and ameliorated diabetic dyslipidemia in a mouse model. However, we could not provide a precise molecular mechanism. To further evaluate the functions of hydrolyzed SF on the pancreatic β-cell, we investigated the effects of hydrolyzed SF on the pancreatic β-cell proliferation and regeneration in the mouse model. Hydrolyzed SF induced the expression of the proliferating cell nuclear antigen (PCNA) and reduced the apoptotic cell population in the pancreatic islets. Hydrolyzed SF treatment not only induced the expression of transcription factors involved in the pancreatic β-cell regeneration in RT-PCR results but also increased neurogenin3 and Neuro D protein levels in the pancreas of those in the group treated with hydrolyzed SF. In line with this, hydrolyzed SF treatment generated insulin mRNA expressing small cell colonies in the pancreas. Therefore, our results suggest that the administration of hydrolyzed SF increases the pancreatic β-cell proliferation and regeneration in C57BL/KsJ-Leprdb/db mice.

Complementary and alternative medicine use among patients with type 2 diabetes living in the United Arab Emirates. BMC Complement Med Ther 2020; 20:216. [PMID: 32650773 PMCID: PMC7350641 DOI: 10.1186/s12906-020-03011-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 07/02/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The use of Complementary and Alternative Medicine (CAM) among Type 2 Diabetes Mellitus (T2DM) patients is increasing to manage the complexities of their condition, enhance their health, and ease complications. The burden of T2DM in the United Arab Emirates (UAE) coupled with the high prevalence of CAM use and its associated risks among patients with T2DM necessitated the investigation of the use of CAM by this patients' population. The aim of this study is to examine the prevalence, types, and correlates of CAM use among T2DM patients in the UAE. METHODS Patients with T2DM attending the outpatient clinics in the two governmental hospitals in Dubai and Sharjah, UAE were invited to participate in a cross-sectional survey. Face-to-face interviews were conducted with participants to complete a multi-component questionnaire. The questionnaire comprised of three main sections: demographic data, diabetes-related information, and CAM use details. Data analysis employed descriptive statistics, univariate and multivariate logistic regression to assess the prevalence and correlates of CAM use. RESULTS Two hundred forty-four T2DM patients completed the questionnaire (response rate: 80%). A total of 39.3% of participants were CAM users since diagnosis. After adjustment; the logistic regression results showed that CAM use was significantly associated with age, sex, education, employment, and having health insurance. The most commonly used type of CAM by participants were folk foods and herbs followed by spiritual and natural healing and vitamins and minerals supplements. The majority of CAM users were referred or encouraged to use CAM by family (42.7%), friends (25%) or social media (17.7%). Only 13.5% of participants used CAM because it was suggested by health care practitioners. Only 1 in four of CAM users disclosed CAM use to their treating physician. CONCLUSION CAM use among T2DM patients in the UAE is considerably high. Health policy and decision-makers are encouraged to dedicate particular attention to facilitating proper regulation and integration of CAM within conventional medicine to protect the health and wellbeing of patients. A concerted effort by medical schools and public health authorities should be committed to educating health care providers and patients on the safe and effective use of CAM therapies.

[PMID: 32543210 DOI: 10.1089/acm.2019.0375] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/24/2022] Open
Abstract
Objectives: Traditional Chinese medicine (TCM) has been shown to reduce insulin resistance and improve beta cell function in previous studies. The aim of this study was to assess whether the use of TCM can delay the need for insulin therapy in patients with type 2 diabetes. Design: Data on patients with type 2 diabetes who received medical treatment for the first time between 2000 and 2003 were obtained from National Health Insurance Research Database (NHIRD) in Taiwan. Among these patients, those with a cumulative use of TCM of more than 28 days were defined as TCM users, and the others as non-users. Kaplan-Meier analysis was used to evaluate the cumulative risk of initiating insulin therapy. Cox proportional hazards models with and without competing risk events were used to evaluate the association between the use of TCM and insulin therapy. Settings/Location: Data were obtained from National Health Insurance Research Database (NHIRD) in Taiwan. Subjects: Patients with type 2 diabetes who received medical treatment for the first time between 2000 and 2003. Interventions: Among these patients, those with a cumulative use of TCM of more than 28 days were defined as TCM users, and the others as non-users. Outcome measures: After 1:1 propensity score matching, both groups were tracked until the initiation of insulin therapy, death, or the end of 2013. Results: We identified 6524 TCM users and 6524 non-users. The TCM users had a significantly lower risk of insulin initiation in a dose-dependent manner (log-rank test p < 0.001). This effect was consistent across subgroups with different severities of diabetes, and remained significant in competing risk analysis (for TCM users with 28 to 83 days cumulative use, HR 0.78 [0.70-0.87], p < 0.0001; for TCM users with ≥ 84 days cumulative use, HR 0.47 [0.42-0.53], p < 0.0001). Conclusions: The use of TCM in addition to standard diabetes treatment may delay the need for insulin treatment in patients who received medical treatment for type 2 diabetes for the first time. This benefit was strongly dose-dependent and applicable in patients with different severities of diabetes.

Abstract
The traditional Chinese medicine has long been used in the treatment of diabetes, one major disease threatening the public health. It has been reported that artemether exerts antidiabetic effects on type 2 diabetes in db/db mice, however the underlying mechanisms remain unknown. In the present study, we show that artemether regulates expression of related enzymes participating in the glucose and lipid metabolism in the liver of db/db mice, which could at least partly explain the improved glucose and lipid metabolism in artemether-treated mice. Additionally, artemether also regulates expression of glycogen synthesis related enzymes in the skeletal muscle of db/db mice, supporting its promotive role in glycogen synthesis. Mechanistically, artemether activates AMPK pathway as well as PI3K/Akt pathway in the liver and skeletal muscle of db/db mice, suggesting that these two signaling pathways are both involved in the antidiabetic effects of artemether on type 2 diabetes in db/db mice. In conclusion, our study connects the antidiabetic effects of artemether to the regulation of metabolic enzymes and signaling pathways, and also provides molecular basis for the potential application of artemether in treating type 2 diabetes.

Abstract
This study was undertaken to investigate the Crataegus extract (CE) eff ;ects on diabetes-induced memory deficit in passive avoidance learning (PAL), blood glucose, and lipid profile panel. Male Wistar rats were divided into five groups: Control (CTRL); Diabetic (DM); and Diabetic animals treated with three doses of CE (100, 300 and 1000 mg/kg) (DM + CE). Streptozotocin (STZ)-induced diabetic rats (50 mg/kg, ip) were orally administrated with CE once a day for 2 weeks. After 2 weeks, PAL task was used to evaluate the passive avoidance learning and memory. At the end of experiment, the level of plasma glucose, triglycerides (TG), cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were determined. Our results showed that the step-through latency (STLr) in diabetic animals was less than the control group (P = 0.0009). Crataegus (300 mg) increased STLr in diabetic animals (P = 0.0418). Diabetic animals spent more time in the dark compartment (TDC) (P = 0.0009). Crataegus (300 and 1000 mg) decreased TDC in diabetic animals (P = 0.0175). Crataegus (100 and 300 mg) decreased blood glucose in diabetic animals (P < 0.001). TG and Cholesterol concentration increased in diabetic animals in comparison with control (P < 0.05). CE (100 and 300 mg) reduced the cholesterol concentration in diabetic animals (P < 0.001). There was no significant difference in the case of LDL among the experimental groups (P > 0.05). CE (1000 mg) increased HDL in diabetic animals (P < 0.05). Our findings demonstrated that CE had the hypolipidemic and hypoglycemic effects and lead to memory improvement in STZ-induced diabetes.

Abstract
Objectives: To investigate the neuroprotective effect of Astragalus injection in a spinal cord ischemia-reperfusion (I/R) injury model. Methods: A total of 27 Sprague Dawley rats were randomly divided into 3 groups: control group (n=3), I/R group (n=12), and Astragalus injection group (Ast group, n=12). Spinal cord ischemia was induced by occlusion of the abdominal aorta above the right renal artery for 32 min. Animals in the Ast group were administered Astragalus injection (6.42 mL/kg) at 30 min before the induction of ischemia. After reperfusion for 8, 12, 24, or 48 hours, the serum neuron-specific enolase (NSE) concentration was measured by enzyme-linked immunosorbent assay (ELISA) and the aquaporin-4 (AQP4) protein level was detected by western blotting. Results: The pathological changes, as assessed by hematoxylin and eosin (HE) staining, were milder in the spinal cords of the Ast group compared to the I/R group. Enzyme-linked immunosorbent assay demonstrated that the NSE concentration of the Ast group was significantly lower than that of the I/R group (p<0.05). However, the NSE concentrations of the I/R and Ast groups were significantly higher than that of the control group (p=0.05). Additionally, the expression of AQP4 in the Ast group was lower than that of the I/R group at each time point. Conclusion: These findings indicate that Astragalus injection has a neuroprotective effect in spinal cord I/R injury by decreasing the AQP4 expression.

Abstract
Diabetes mellitus is one of the major health problems in the world, the incidence and associated mortality are increasing. Inadequate regulation of the blood sugar imposes serious consequences for health. Conventional antidiabetic drugs are effective, however, also with unavoidable side effects. On the other hand, medicinal plants may act as an alternative source of antidiabetic agents. Examples of medicinal plants with antidiabetic potential are described, with focuses on preclinical and clinical studies. The beneficial potential of each plant matrix is given by the combined and concerted action of their profile of biologically active compounds.

Kasole R, Martin HD, Kimiywe J. Traditional Medicine and Its Role in the Management of Diabetes Mellitus: "Patients' and Herbalists' Perspectives". EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2019; 2019:2835691. [PMID: 31354852 PMCID: PMC6637672 DOI: 10.1155/2019/2835691] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/08/2019] [Revised: 05/01/2019] [Accepted: 06/17/2019] [Indexed: 11/17/2022]
Abstract
BACKGROUND Diabetes mellitus is a complicated health condition with multiple causes and many treatment options. Various myths may influence diabetics' health-seeking behavior, and they may use traditional medicines, which include normal foods and herbs, for primary health care. The aim of this study was to determine patients' and herbalists' practices and perspectives regarding the use of traditional medicines and the role of traditional medicines in the management of diabetes. METHODS AND FINDINGS We conducted a cross-sectional study with a mixed-methods design. We interviewed 140 patients attending diabetic clinics using a structured questionnaire, conducted focus group discussions with an additional 20 diabetic patients, and conducted in-depth interviews with 8 local herbalists. The majority of the diabetic participants believed that diabetes is caused by a high-carbohydrate diet. Of the 140 participants who answered the questionnaire, 67.2% reported using traditional medicines to manage their diabetes, including 58.6% who reported using both conventional medicines and traditional medicines. Some participants believed that combining conventional and traditional medicines improved the effectiveness of treatment. Reasons given for using traditional medicines included the high cost of conventional treatment and the availability and accessibility of the traditional medicines. The most commonly used traditional medicines were indigenous vegetables and medicinal plant products including amalanth leaves, hare lettuce leaves, nightshade leaves, spider plant leaves, okra pods, moringa leaves and seeds, soursop leaves, black plum back, avocado seed, and lemongrass. CONCLUSION Patients and herbalists provided a range of perspectives regarding the use of traditional medicines to treat diabetes. Further research is needed to identify bioactive compounds present in commonly used traditional medicines and their efficacy.

Abstract
We conducted a systematic review and meta-analysis to evaluate the effect of Berberine on glucose in patients with type 2 diabetes mellitus and identify potential factors may modifying the hypoglycemic effect. We searched PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang Database to identify randomized controlled trials that investigated the effect of Berberine. We calculated weighted mean differences (WMD) and 95% confidence interval (CI) for fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and glycated haemoglobin (HbA1c) levels. Twenty-eight studies were identified for analysis, with a total of 2,313 type 2 diabetes mellitus (T2DM) patients. The pool data showed that Berberine treatment was associated with a better reduction on FPG (WMD = -0.54 mmol/L, 95% CI: -0.77 to -0.30), PPG (WMD = -0.94 mmol/L, 95% CI: -1.27 to -0.61), and HbA1c (WMD = -0.54 mmol/L, 95% CI: -0.93 to -0.15) than control groups. Subgroup-analyses indicated that effects of Berberine on blood glucose became unremarkable as the treatment lasted more than 90 days, the daily dosage more than 2 g/d and patients aged more than 60 years. The efficiency of Berberine combined with hypoglycaemics is better than either Berberine or hypoglycaemic alone. The dosage and treatment duration of Berberine and patients' age may modify the effect.

Abstract
The objective of this article is to explore the clinical efficacy of acupuncture therapy of Traditional Chinese Medicine (TCM) combined with Astragalus injection in the treatment of children with diarrhea-predominant irritable bowel syndrome (IBS), and its effects on 5-hydroxytryptamine (5-HT), neuropeptide Y (NPY), and calcitonin gene-related peptide (CGRP) in peripheral blood. A total of 116 children with diarrhea-predominant IBS admitted to our hospital from January 2017 to January 2018 were randomly divided into two groups. The control group was treated with Astragalus injection, while the research group was treated with acupuncture therapy of TCM combined with Astragalus injection. The therapeutic effects, the concentrations of CGRP, NPY, and 5-HT in peripheral blood were compared between the two groups. The therapeutic efficacy of the study group was better than that of the control group ( P < 0.05). The concentrations of CGRP, NPY, and 5-HT in the peripheral blood of the study group were less than those of the control group ( P < 0.05). Acupuncture therapy of TCM combined with Astragalus injection has a satisfactory effect in the treatment of children with diarrhea-predominant IBS, which is worthy of more publicity and application in the clinic.

Abstract
BACKGROUND Yellow tongue coating is one of the clinical signs for diabetes mellitus according to traditional East Asian medicine. Few reports have been available on the association between yellow tongue coating and the prevalence of type 2 diabetes in the general population. We examined that association among population samples of non-smoking men and women. METHODS The study subjects were Japanese non-smoking men (n = 315) and women (n = 654) aged 30-79 years who resided in Toon city and participated in the Toon Health Study from July 2011 through November 2014. Tongue coating was assessed by a nationally licensed acupuncturist and classified into three categories of white (normal), light yellow, and yellow. We performed an oral glucose tolerance test to confirm the presence of diabetes mellitus and prediabetes. The associations between yellow tongue coating and the prevalence of diabetes mellitus and prediabetes were examined using multivariable logistic regression analyses, adjusting for age, sex, body mass index, drinking status, and physical activity. RESULTS The multivariable odds ratios of diabetes mellitus were 1.39 (95% confidence interval [CI], 0.72-2.67) for light yellow tongue coating and 2.23 (95% CI, 1.16-4.30) for yellow tongue coating compared with white tongue coating. The respective multivariable odds ratios of prediabetes were 1.13 (95% CI, 0.80-1.61) and 1.43 (95% CI, 0.96-2.12). CONCLUSIONS Yellow tongue coating was associated with higher prevalence of diabetes mellitus and tended to be associated with that of prediabetes among Japanese non-smoking men and women.

Abstract
BACKGROUND Injection of snakegourd peel (SP), an herb used in traditional Chinese medicine, is used to treat coronary artery disease and stable angina in China. However, its therapeutic role and mechanism of action for the treatment of myocardial infarction (MI) is not fully understood. PURPOSE The present study was designed to investigate the effect of SP on MI-induced cardiac injury and elucidate its underlying molecular mechanisms. METHODS To create an in vivo model of MI, we ligated the left coronary artery of Wistar rats. For our in vitro model of MI, we treated primary neonatal rat ventricular myocytes with hypoxia. Myocardial infarct size was measured by triphenyltetrazolium chloride (TTC) staining. Intracellular calcium concentration (Ca2+) was measured by confocal microscopy, and cardiomyocyte apoptosis was assessed by TUNEL assay. Western blot was applied to determine protein levels. RESULTS Three days post-MI, SP significantly improved MI-induced impairment of cardiac function, as indicated by increased left ventricular systolic pressure (LVSP), maximum rate of left ventricular pressure rise and fall (± dp/dt max), and decreased left ventricular end-diastolic pressure (LVEDP). In addition, SP treatment markedly reduced the infarct size and serum lactate dehydrogenase (LDH) activity; inhibited cardiomyocyte apoptosis and Caspase-3 activation both in vivo and in vitro; and decreased intracellular calcium overload, Cav1.2, phosphorylated JNK (p-JNK), and p38 MAPK (p-p38 MAPK) levels in ischemic myocardium. CONCLUSION SP alleviated cardiac ischemic injury and inhibited cardiomyocyte apoptosis by attenuating intracellular calcium overload, suppressing Caspase-3 activation, and downregulating protein expression of p-JNK and p-p38MAPK. These results suggest that SP may serve as a potential novel therapeutic drug for MI.

Abstract
Type 2 diabetes mellitus (T2DM), a chronic metabolic disease which severely impairs peoples' quality of life, currently attracted worldwide concerns. There are growing evidences that gut microbiota can exert a great impact on the development of T2DM. Xiexin Tang (XXT), a traditional Chinese medicine prescription, has been clinically used to treat diabetes for thousands of years. However, few researches are investigated on the modulation of gut microbiota community by XXT which will be very helpful to unravel how it works. In this study, bacterial communities were analyzed based on high-throughput 16S rRNA gene sequencing. Results indicated that XXT could notably shape the gut microbiota. T2DM rats treated with XXT exhibited obvious changes in the composition of the gut microbiota, especially for some short chain fatty acids producing and anti-inflammatory bacteria such as Adlercreutzia, Alloprevotella, Barnesiella, [Eubacterium] Ventriosum group, Blautia, Lachnospiraceae UCG-001, Papillibacter and Prevotellaceae NK3B31 group. Additionally, XXT could also significantly ameliorate hyperglycemia, lipid metabolism dysfunction and inflammation in T2DM rats. Moreover, the correlation analysis illustrated that the key microbiota had a close relationship with the T2DM related indexes. The results probably provided useful information for further investigation on its active mechanism and clinical application.

Abstract
Diabetes affects 422 million people and directly caused 4.9 million deaths according to the global report on diabetes in 2014. Type 2 diabetes accounts for 90% of people with diabetes around the world. Chinese herbal medicine treatment for diabetes has more than 2000-year history in China. An increasing number of people around the world are trying to manage type 2 diabetes with Chinese herbal medicine. However, there is a lack of evidence to decide if Chinese herbal medicine is effective and safe when compared with other interventions for the treatment of type 2 diabetes We identified 58 randomized controlled trials involving 6637 participants with type 2 diabetes with trial periods lasting from 8 weeks to 1 year (average 12 weeks). We extracted data following a predefined hierarchy. A total of 132 different Chinese herbal medicines were examined. We included studies comparing Chinese herbal medicine with other interventions and excluded trials that did not satisfy the inclusion criteria. We evaluated primary outcomes of trials in accordance with the Cochrane Handbook for Systematic Reviews of Intervention. Fifty-six out of 58 studies reported evidence that Chinese herbal medicines were effective at controlling blood sugar, insulin resistance, and traditional Chinese medicine clinical symptoms for patients with type 2 diabetes. And outcome variables are summarized. However, the evidence is limited because of the quality of the studies. Well-designed long-term studies with large samples and multiple centers as well as standardization and quality control will be required to determine if Chinese herbal medicine treatment is effective and safe for type 2 diabetes.

Abstract
PURPOSE OF REVIEW This review focuses on evaluating and identifying gaps in the current literature regarding culturally specific dietary influences for patients with type 2 diabetes. As this topic has previously been examined in African American populations, we chose to focus on four other distinct populations (Hispanic, Middle Eastern, Western Pacific, South Asian). Given the rapid increase in global rates of type 2 diabetes and high rates of diabetes among certain ethnic groups, it is important to understand how culturally adapted strategies in diabetes management have been described in different regions and populations. RECENT FINDINGS The specific role of nutrition in controlling diabetes is tied to cultural habits and customs. Variation in cultural practices, including diet, create unique environments in which patients with diabetes must navigate. The role of family, particularly among Hispanics, is crucial to cultural adaptations of diabetes management. Incorporating alternative medicine, namely observed in Chinese and Indian populations, also guided diabetes care strategies. Language barriers, health literacy, and acculturation were all unique factors affecting cultural approaches to diabetes management in these four populations. Understanding such cultural determinants is crucial to addressing diabetes disparities and improving outcomes.

Abstract
The rapidly increasing diabetes mellitus (DM) is becoming a major global public health issue. Traditional Chinese medicine (TCM) has a long history of the treatment of DM with good efficacy. Huangqi and Huanglian are one of the most frequently prescribed herbs for DM, and the combination of them occurs frequently in antidiabetic formulae. However, the synergistic mechanism of Huangqi (Radix Astragali) and Huanglian (Rhizoma Coptidis) has not been clearly elucidated. To address this problem, a feasible system pharmacology model based on chemical, pharmacokinetic and pharmacological data was developed via network construction approach to clarify the synergistic mechanisms of these two herbs. Forty-three active ingredients of Huangqi (mainly astragalosides and isoflavonoids) and Huanglian (primarily isoquinoline alkaloids) possessing favorable pharmacokinetic profiles and biological activities were selected, interacting with 50 DM-related targets to provide potential synergistic therapeutic actions. Systematic analysis of the constructed networks revealed that these targets such as GLUT2, NOS2, PTP1B, and IGF1R were mainly involved in PI3K-Akt signaling pathway, insulin resistance, insulin signaling pathway, and HIF-1 signaling pathway, and were mainly located in retina, pancreatic islet, smooth muscle, immunity-related organ tissues, and whole blood. The contribution index of every active ingredient also indicated five compounds, including berberine (BBR), astragaloside IV (AIV), quercetin, palmatine, and astragalus polysaccharides, as the principal components of this herb combination. These results successfully explained the polypharmcological and synergistic mechanisms underlying the efficiency of Huangqi and Huanglian for the treatment of DM and its complications.

Abstract
AIM Early interventions in prediabetes can prevent or delay the incidence of type 2 diabetes mellitus (T2DM). The aim of this review was to assess the efficacy and safety of traditional Chinese patent medicine (TCPM) on the prevention of T2DM. METHODS Seven electronic databases were searched to identify eligible trials published until June 1, 2016. Randomized controlled trials (RCTs) that compared TCPM plus lifestyle modification (LM) versus LM alone were included for in the. RCTs that used TCPM plus LM compared with placebo plus LM were also included. Methodological quality was assessed using the Cochrane Collaboration Risk of Bias tool. A random- or fixed-effect model was used to analyze outcomes that were expressed as risk ratios (RRs) or mean differences (MD), and the I2 statistic was used to assess heterogeneity. RESULTS Twenty-six trials with a total of 4169 participants met the inclusion criteria. Subgroup analysis confirmed that, compared with LM alone, TCPM and LM together were significantly better at reducing diabetes (RR, 0.47; 95% CI, 0.38-0.59) and normalizing blood glucose (RR, 0.76; 95% CI, 0.69-0.85). They also caused a greater reduction in fasting plasma glucose (FBG) (MD, -0.37; 95% CI, -0.62 to -0.13), 2-h plasma glucose (2h PG) (MD, -0.91; 95% CI, -1.35 to -0.47) and body mass index (BMI) (MD, -0.45; 95% CI, -0.76 to -0.14). Compared with placebo plus LM, TCPM plus LM was superior at reducing diabetes (RR, 0.55; 95% CI, 0.45-0.68) and normalizing blood glucose (RR, 0.62; 95% CI, 0.50-0.76). The interventions were also associated with a decline in FBG levels (MD, -0.68; 95% CI, -1.25 to -0.11) and 2h PG levels (MD, -1.07; 95% CI, -1.85 to -0.29). There were no significant differences in adverse events in either group. Subgroup and sensitivity analyses found no significant difference in overall effects among all study characteristics, indicating that the overall effects were stable. Generally, the quality of evidence was low for the effect of TCPM on the incidence of diabetes and normalization of blood glucose, and was very low for the effects of TCPM on FBG, 2h PG, and BMI. CONCLUSIONS Based on this systematic review, TCPM may reduce the risk of progression to T2DM and increase the possibility of regression toward normoglycemia. As a result of the methodological drawbacks of the included studies, more rigorously designed RCTs are required to more reliably assess the efficacy of TCPM and long-term follow-up is needed before TCPM can be recommended for prediabetic patients.

Antidiabetic Micro-/Nanoaggregates from Ge-Gen-Qin-Lian-Tang Decoction Increase Absorption of Baicalin and Cellular Antioxidant Activity In Vitro. BIOMED RESEARCH INTERNATIONAL 2017; 2017:9217912. [PMID: 28798936 PMCID: PMC5536148 DOI: 10.1155/2017/9217912] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Accepted: 05/25/2017] [Indexed: 12/03/2022]
Abstract
The antidiabetic effects of Ge-Gen-Qin-Lian-Tang decoction (GQD) have been proven clinically. In a pharmacological study conducted on STZ-induced diabetic rats, the constitutive aggregates/sediments of Ge-Gen-Qin-Lian-Tang decoction exhibited stronger hypoglycemic and antioxidant activities compared to the soluble compositions. This study aims to demonstrate the pharmacological properties of aggregates derived from GQD by measuring permeability of the active monomer phytochemicals (e.g., baicalin) in a Caco-2 cell monolayer and determine the cellular viability, intracellular redox status (MDA and SOD), and insulin secretion of pancreatic β-cell line, INS-1, following STZ-induced oxidative stress. The aggregates were separated into three fractions, namely, “MA (microaggregates),” “400 g supernatant,” and “MNA (micro-/nanoaggregates),” by centrifugation at 400 ×g and 15000 ×g, respectively. Aggregates in the sediment increased baicalin absorption, showed little toxicity to β-cells, elevated intracellular SOD levels, and significantly suppressed oxidative damage effects on cellular viability and functions. The “MA” fraction had a larger particle size and provided higher antioxidant cellular protection than “MNA” in vitro, implying that the sediments may be the active components in the herbal decoction. The actions of these micro-/nanoaggregates may provide a new perspective for understanding the antidiabetic effects of herbal decoctions and aid in interpretation of synergistic actions between the multiple components.

Abstract
In this article, we introduce briefly several strategies for preventing atherosclerotic cardiovascular disease and promoting healthcare for non-communicable diseases (NCDs). These novel strategies include four core elements of health – sleep, emotion, exercise, and diet – and consist of SEED intervention (SEEDi) and E(e)SEEDi due to supplementation of the environment as a core element, and Hu's healthy lifestyles intervention (HHLi) which originates from E(e)SEED-BasED healthy lifestyles. They are suitable for the early evaluation of risk factors, and play a key role in the prevention and management of human NCDs when combined with the RT-ABCDEF strategy and the Grade 210 prevention, which include obesity-OSA-hypertension syndrome and C-type hypertension, especially in halting cardiovascular, diabetes and cancer (CDC) strips we first discovered. After successful clinical practice, we may expect our novel strategies for controlling these chronic diseases according to the conception of mass prevention and treatment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE With the mounting pandemic of glucose metabolism dysregulation and type 2 Diabetes Mellitus (T2DM), traditional medicine such as traditional Chinese medicine (TCM) recipes has been widely adopted as a part of therapeutic approach, especially in Asian countries. AIM OF THE STUDY A novel approach, which is adopted from cohort studies from epidemiology has been applied to explore the clinical efficacy, as well as the herbal component selection of a variety of TCM formulations against T2DM. MATERIALS AND METHODS In the current study, 98 newly diagnosed T2DM patients were recruited in two hospitals. Over a span of 4 weeks, the patients were treated by prescriptions of their individual TCM physicians. General TCM symptoms, blood glucose parameters, as well as general metabolic health biomarkers were evaluated over the therapy period. The pattern of which herbs were used, together with association between blood glucose level change and the use of herbs, were analyzed. RESULTS TCM diabetic syndrome diagnosis was made by physicians based on symptoms, who prescribed herbal TCM medication afterwards for individual subjects. The results showed significant reduction in fasting and postmeal glucose levels, as well as insulin after the TCM treatment regimen as compared to baseline. As secondary endpoint, total triglyceride level decreased over the period of study as well. Kudzuvine root, Rhemannia root, Figwoot root, and Mulberry leaf were the top herbs associated with pronounced glucose reduction. CONCLUSIONS In conclusion, an observational study on a cohort of patients receiving TCM therapy has shown good clinical outcome for T2DM patients receiving TCM treatments. Association analysis on herbal usage and clinical outcome suggested opportunity in constructing optimized formulation for superior efficacy with future studies at a larger scale.

Abstract
Traditional Chinese medicine (TCM) is an important complementary strategy for treating diabetes mellitus (DM) in China. Traditional Chinese blood circulation activating drugs are intended to guide an overall approach to the prevention and treatment of microvascular complications of DM. The core mechanism is related to the protection of the vascular endothelium and the basement membrane. Here, we reviewed the scientific evidence underpinning the use of blood circulation activating drugs to prevent and treat DM-induced microvascular complications, including diabetic nephropathy (DN), diabetic peripheral neuropathy (DPN), and diabetic retinopathy (DR). Furthermore, we summarized the effects and mechanism of TCM on improving blood rheology, inhibiting aggregation of platelet, forming advanced glycation end products (AGEs), regulating oxidative stress, reducing blood fat, and improving lipid metabolism. The paper provides a new theoretical basis for the clinical practice of TCM in the prevention and treatment of DM and its microvascular complications.

Differential HbA1c response in the placebo arm of DPP-4 inhibitor clinical trials conducted in China compared to other countries: a systematic review and meta-analysis. BMC Pharmacol Toxicol 2016; 17:40. [PMID: 27600598 PMCID: PMC5013632 DOI: 10.1186/s40360-016-0084-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2015] [Accepted: 08/03/2016] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND It has been observed that the efficacy of dipeptidyl peptidase-4 (DPP-4) inhibitors as compared to the placebo groups in some clinical trials conducted in China is weaker than that in trials conducted outside China, leading to the suspicion that this may be caused by differential Glycosylated Hemoglobin (HbA1c) response in the placebo arm of DPP-4 inhibitor clinical trials conducted in China compared to other countries. METHODS We searched published articles and other documents related to phase III placebo-control trials of DPP-4 inhibitors in Type 2 diabetes mellitus (T2DM). We included studies from different countries and compared those conducted in China to those conducted in other countries. Meta-regression analysis was used to analyze the HbA1c response in the placebo arms. RESULTS A total of 66 studies met the inclusion criteria and 10 were conducted within China. There were a total of 8303 participants (mean age 56, male 57 %) in placebo groups. The pooled change in HbA1c for the placebo groups of 10 trials conducted in patients with T2DM in China was 0.26 % (95 % CI [-0.36 %, -0.16 %], p-value < 0.001), compared to 0.015 % (95 % CI [-0.05 %, 0.08 %], p-value is 0.637) for 56 trials conducted outside of China. The difference of placebo effect between trials conducted in and outside China is -0.273 % (95 % CI [-0.42 %, -0.13 %], p-value is less than 0.001) while after excluding trials conducted in Japan, the difference is -0.203 % (95 % CI [-0.35 %, -0.06 %], p-value is 0.005). They are both statistically significant. CONCLUSIONS The meta-analysis in the article demonstrates that there is statistically significant difference in the HbA1c response in the placebo arm of DPP-4 inhibitor clinical trials conducted in China compared to other countries. This differential HbA1c response in the placebo arm should be taken into consideration by both experimenters and medical decision makers when future DPP-4 studies are conducted in China.

Abstract
This study investigated the active principles, hypoglycemic activity and potential mechanisms of the flavonoid rich extract from Sophora tonkinensis Gagnep. (ST-EtOAc) in KK-Ay diabetic mice. An off-line semipreparative liquid chromatography-nuclear magnetic resonance (LC-NMR) and liquid chromatography-ultraviolet-electrospray ionization mass spectrometry (LC-UV–ESIMS) protocol was performed to determine 13 flavonoids from ST-EtOAc. ST-EtOAc administrated orally to the KK-Ay mice significantly increased their sensibility to insulin, reduced fasting blood-glucose levels and blood lipid indexes such as triglyceride and cholesterol. Moreover, ST-EtOAc exhibited a strong effect of stimulation on glucose transporter 4 (GLUT4) translocation by 2.7-fold in L6 cells. However, the selective AMP-activated protein kinase (AMPK) inhibitor compound C can completely inhibit the activation of the AMPK pathway and prevent the GLUT4 translocation caused by ST-EtOAc. In vivo, phosphorylation of the AMPK expression in the liver and skeletal muscle was measured. The results showed phosphorylation of the AMPK had been improved and GLUT4 expression had been also enhanced. In this paper, we conclude that, ST-EtOAc seems to have potential beneficial effects on the treatment of type 2 diabetes mellitus with the probable mechanism of stimulating GLUT4 translocation modulated by the AMPK pathway.

Abstract
Background Astragalus injection is used by practitioners of traditional Chinese medicine to treat diabetic nephropathy (DN). The current study was conducted to determine the effect of astragalus on tubular epithelial transdifferentiation during the progression of DN in KKAy mice, as well as to investigate the molecular mechanism underlying this effect. Methods Diabetic, 14-week-old, male KKAy mice were randomly divided into a model group and an astragalus treatment group, while age-matched male C57BL/6 J mice were selected as controls. The treatment group received daily intraperitoneal injections of astragalus (0.03 mL/10 g per day), while the model group received injections of an equal volume of saline. Mice were euthanized after 24 weeks. Serum samples were obtained from the animals in each group for blood glucose measurement. Kidney tissue samples were used for morphometric studies. The mRNA and protein expression levels of transforming growth factor beta 1 (TGF-β1), transforming growth factor beta receptor 1 (TGFβ-R1), alpha smooth muscle actin (α-SMA), and E-cadherin were evaluated using real-time polymerase chain reaction (PCR) and western blotting. Results Astragalus significantly reduced blood glucose levels; inhibited morphological changes in the kidneys of KKAy mice; reduced mRNA and protein expression levels of TGF-β1, TGFβ-R1, and α-SMA; and increased E-cadherin expression. Conclusions Tubular epithelial transdifferentiation plays an important role in the development of DN in diabetic mice. Administration of astragalus likely prevents or mitigates DN by suppressing tubular epithelial transdifferentiation, protecting KKAy mice from renal damage.

Abstract
The present study investigated the synergic effects and potential mechanisms of action of Astragalus polysaccharides (APS) combined with Crataegus flavonoids (CF) in the treatment of type 1 diabetes. Diabetes was induced by intraperitoneal injection of 100 mg/kg streptozotocin in mice. Normal and untreated diabetic control mice were used, and CF‑treated (200 mg/kg/day), APS‑treated (200 mg/kg/day), APS + CF (AC)‑treated (200 mg/kg/day of each) and metformin‑treated (200 mg/kg/day) diabetic mice were orally administrated the appropriate therapeutic agent for 4 weeks. The results demonstrated that AC treatment significantly reduced the fasting blood glucose, food and water intake in the diabetic mice. The AC group demonstrated increased serum insulin levels and islet cell function was restored. Furthermore, the AC‑treated mice demonstrated significant increases in the protein expression levels of pancreatic and duodenal homeobox‑1 and phosphorylated adenosine 5'‑monophosphate‑activated protein kinase in the pancreatic and liver tissue samples, respectively. In addition, AC significantly increased the mRNA expression levels of neurogenin 3, v‑maf musculoaponeurotic fibrosarcoma oncogene family, protein A and insulin, and simultaneously decreased the expressions of interleukin 6, tumor necrosis factor‑α and chemokine (C‑C motif) ligand 2 in the pancreatic islet cells of diabetic mice. The anti‑inflammatory activity of APS and the islet‑restoring effect of CF may contribute to the improvement of islet function. AC exerted greater antidiabetic effects compared with APS or CF treatments alone. These results indicated that AC treatment had a synergic antidiabetic effect, which may involve improvements in islet function and liver metabolism. These effects of AC may facilitate the treatment of type 1 or 2 diabetes, as these patients frequently experience impaired islet function and disordered extrapancreatic metabolism.

Abstract
BACKGROUND Diabetes is a metabolic disorder caused by oxidative stress and inflammation. JianYuTangKang (JYTK), as a potential Chinese integrative medicine, is an antioxidant used in Chinese medicine with potential anti-inflammatory properties. OBJECTIVES The present randomized clinical trial was carried out to evaluate the effects of JYTK on oxidative stress and inflammation in patients with type 2 diabetes mellitus (T2DM). PATIENTS AND METHODS The parallel, randomized, double-blinded, placebo-controlled clinical trial included 150 newly diagnosed T2DM patients receiving metformin treatment (1.5 g/day), some of whom also received JYTK (4.5 g/day) in tablet form. The control group received 4.5 g/day placebo plus 1.5 g/day metformin. Body mass index (BMI), fasting plasma glucose, urinary albumin-to-creatinine ratio, and complete blood count as well as antioxidant and inflammation indices such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GPX), and high sensitivity C-reactive protein (hs-CRP) levels were assessed at baseline and at different time points during the treatment. RESULTS All 112 patients, including 59 in the treatment group (JYTK + metformin) and 52 controls (metformin only) completed the 26-week clinical trial. JYKT plus metformin treatment increased IL-6 (36.4 ± 11.5 ng/L; P < 0.05), TNF-α (17.5 ± 11.3 vs. 22.5 ± 12.9 ng/L; P < 0.05), and MDA (1.9 ± 0.9; P < 0.05) levels compared to the control (2.2 ± 0.6 mM/mL), whereas total SOD level decreased (98.1 ± 30.4 vs. 78.5 ± 29.3 U/mL; P < 0.05). There were no changes in GPX and hs-CRP levels. There were no adverse effects associated with JYTK treatment. CONCLUSIONS JYTK combined with metformin improves some antioxidant indices (SOD and MDA), and decreases inflammation in patients with T2DM, suggesting that it can reduce the risk of diabetic complications.

Abstract
Introduction Peppermint is an efficient medicinal plant for the treatment of diseases, and it also can be used to produce raw materials in the pharmaceutical industry. The purpose of the current study was to evaluate the effects of various levels of peppermint alcoholic extract on body-weight gain and blood biochemical parameters in adult male Wistar rats. Methods This experiment was conducted using a completely randomized design (CRD). Fifty adult, healthy, male Wistar rats (ages of 2.5–3 months; weights of 190–210 g) were allocated randomly into five groups. T1 was the control group in which the rats received 0.3 ml of distilled water). Groups T2, T3, T4, and T5 received 75, 150, 300, and 600 mg/kg of peppermint extract, respectively. The rats received daily pretreatment by oral gavages for 21 days. We recorded body weights at the beginning and at the end of the study to determine the changes in the body weights. Blood samples were collected for the measurement of glucose, cholesterol, triglycerides, HDL, LDL, albumin, globulin, and total protein. Statistical analysis of the data was done by SAS software. The data statistically analyzed using one-way analysis of variance (ANOVA), which was conducted through Dennett’s multiple comparison post-test. Results The results indicated that the rats treated with peppermint gained more weight (p < 0.05) and also decreased the serum concentrations of triglycerides, total cholesterol, LDL, and glucose in T3, T4 and T5 than the other groups (p < 0.05). Conclusion Peppermint extract had a positive effect on body-weight gain and some blood parameters in adult male Wistar rats. The findings showed that peppermint is a crucial substance at high temperature, and future research should be focused on determining the details of the mechanisms involved in producing the observed effects of peppermint extract.

Abstract
BACKGROUND Many factors influence whether the first-line oral anti-diabetic drug, metformin, should be initiated to a patient with type 2 diabetes mellitus (T2DM) early in the course of management in addition to lifestyle modifications. This study aims to evaluate the net effects of metformin monotherapy (MM) on the all-cause mortality and cardiovascular disease (CVD) events. METHODS A retrospective 5-year follow-up cohort study was conducted on Chinese adult patients with T2DM and without any CVD history under public primary care. Cox proportional hazard regressions were performed to compare the risk of all-cause mortality and CVD events (CHD, stroke, heart failure) between patients receiving lifestyle modifications plus MM (MM groups) and those with lifestyle modifications alone (control groups). RESULTS 3400 pairs of matched patients were compared. MM group had an incidence rate of 7.5 deaths and 11.3 CVD events per 1000 person-years during a median follow-up period of 62.5 months whereas control group had 11.1 deaths and 16.3 per 1000 person-years during a median follow-up period of 43.5-44.5 months. MM group showed a 29.5 and 30-35% risk reduction of all-cause mortality and CVD events (except heart failure) than control group (P < 0.001). MM group was more prone to progress to chronic kidney disease but this was not statistically significant. CONCLUSIONS Type 2 diabetic patients who were started on metformin monotherapy showed improvement in many of the clinical parameters and a reduction in all-cause mortality and CVD events than lifestyle modifications alone. If there is no contraindication and if tolerated, diabetic patients should be prescribed with metformin early in the course of the diabetic management to minimize their risk of having the cardiovascular events and mortality in the long run.
