Sriraman S, Sreejith D, Andrew E, Okello I, Willcox M. Use of herbal medicines for the management of type 2 diabetes: A systematic review of qualitative studies. Complement Ther Clin Pract 2023; 53:101808. [PMID: 37977099 DOI: 10.1016/j.ctcp.2023.101808] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 10/21/2023] [Accepted: 10/25/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Many people with Type 2 Diabetes Mellitus (T2DM) use herbal medicines, some of which can improve glycaemic control. Providing evidence-based advice on herbal medicines could be an effective intervention to improve control of diabetes, if it is designed to address key needs and concerns of T2DM patients. AIM To understand the views and experiences of patients and health professionals on herbal treatments for self-management of T2DM. METHOD MEDLINE, EMBASE, CINAHL, SOCIOFILE and Google Scholar were searched for qualitative studies in T2DM patients about their views on herbal medicines. Included papers were analysed using thematic synthesis. RESULTS Thirty-one papers (about 30 studies) were included: 20 from low-and-middle income countries, 10 from high income countries, and 1 internet-based study. Almost all studies from high income countries focussed on ethnic minorities. Many people with T2DM wanted a "cure", and often took advice from friends and family, but also traditional healers and mass media. However, they were reluctant to discuss herbal medicines with health professionals, whom they perceived as "closed-minded". They based their treatment decisions on personal experience (from "trial-and-error"), availability, cost and convenience of both herbal and conventional medicines. Most health professionals were reluctant to discuss herbal medicines, or recommended against their use, because of lack of knowledge and concerns about their quality, efficacy and potential interactions. CONCLUSION Evidence-based information could help to overcome the current lack of communication about herbal medicines between people with T2DM and health professionals.

Shaukat A, Zaidi A, Anwar H, Kizilbash N. Mechanism of the antidiabetic action of Nigella sativa and Thymoquinone: a review. Front Nutr 2023; 10:1126272. [PMID: 37818339 PMCID: PMC10561288 DOI: 10.3389/fnut.2023.1126272] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 07/27/2023] [Indexed: 10/12/2023] Open
Abstract
Introduction Long used in traditional medicine, Nigella sativa (NS; Ranunculaceae) has shown significant efficacy as an adjuvant therapy for diabetes mellitus (DM) management by improving glucose tolerance, decreasing hepatic gluconeogenesis, normalizing blood sugar and lipid imbalance, and stimulating insulin secretion from pancreatic cells. In this review, the pharmacological and pharmacokinetic properties of NS as a herbal diabetes medication are examined in depth, demonstrating how it counteracts oxidative stress and the onset and progression of DM. Methods This literature review drew on databases such as Google Scholar and PubMed and various gray literature sources using search terms like the etiology of diabetes, conventional versus herbal therapy, subclinical pharmacology, pharmacokinetics, physiology, behavior, and clinical outcomes. Results The efficiency and safety of NS in diabetes, notably its thymoquinone (TQ) rich volatile oil, have drawn great attention from researchers in recent years; the specific therapeutic dose has eluded determination so far. TQ has anti-diabetic, anti-inflammatory, antioxidant, and immunomodulatory properties but has not proved druggable. DM's intimate link with oxidative stress, makes NS therapy relevant since it is a potent antioxidant that energizes the cell's endogenous arsenal of antioxidant enzymes. NS attenuates insulin resistance, enhances insulin signaling, suppresses cyclooxygenase-2, upregulates insulin-like growth factor-1, and prevents endothelial dysfunction in DM. Conclusion The interaction of NS with mainstream drugs, gut microbiota, and probiotics opens new possibilities for innovative therapies. Despite its strong potential to treat DM, NS and TQ must be examined in more inclusive clinical studies targeting underrepresented patient populations.

Anti-Diabetic Effects and Molecular Mechanisms of Amide Alkaloids from Piper longum Based on Network Pharmacology Integrated with Cellular Assays. Chem Biodivers 2023; 20:e202200904. [PMID: 36469428 DOI: 10.1002/cbdv.202200904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 12/05/2022] [Accepted: 12/05/2022] [Indexed: 12/12/2022]
Abstract
Piper longum is a well-known spice and traditional medicine. It was revealed to possess anti-diabetic activity, but few information about its active component and underlying mechanism could be available. In this study, retrofractamides A (1) and C (2) isolated from P. longum showed potent inhibitory activity against PTP1B. Therefore, the potential mechanism was predicted by network pharmacology and molecular docking. PI3K/AKT was obtained as the most remarkable pathway against type 2 diabetes mellitus (T2DM), and AKT1 and GSK3β were yielded as the top two core targets of retrofractamides A (1) and C (2). Molecular docking of compounds with AKT1 and GSK3β showed strong binding affinity between them. Additionally, cellular experiments with a L6 cell model was conducted to further verify the above predictions. Results indicated that retrofractamides A (1) and C (2) exerted anti-diabetic effect via activating PI3K/AKT pathway, and they promoted glucose consumption, glucose uptake, glycogen synthesis and glycolysis.

YiQi YangYin Decoction Attenuates Nonalcoholic Fatty Liver Disease in Type 2 Diabetes Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5511019. [PMID: 34621322 PMCID: PMC8492297 DOI: 10.1155/2021/5511019] [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: 03/01/2021] [Revised: 06/16/2021] [Accepted: 08/31/2021] [Indexed: 01/09/2023]
Abstract
Background YiQi YangYin Decoction (YQ) is a modern Chinese formula composed by the guidance of traditional Chinese medicine theory, which consists of nine traditional Chinese medicines and is applied to treat type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver in clinic in China for more than a decade. This study aims to evaluate the antidiabetes and lipid-lowering effect of YQ and explore the possible mechanisms of this action. Methods T2DM rat models were established and given YQ at three different doses for three weeks. Tissues, including pancreas islet and liver, and blood serum were collected. The levels of fasting blood glucose (FBG), fasting insulin (Fins), lipid index, such as total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL), and hepatic function index such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in serum were measured. Pancreas islet damage and liver damage were observed by hematoxylin and eosin staining. The glycogen content and lipid accumulation in liver were determined by periodic acid-Schiff (PAS) staining and Oil Red O staining. The expression levels of insulin receptor substrate 2 (IRS-2), phosphatidylinositol 3 kinase-associated p85alpha (PI3K p85α), AKT, and Glucose Transporter 2 (Glut4) in pancreas islet and AMP-activated protein kinase alpha (AMPKα), sterol regulatory element-binding protein 1c (SREBP1c), acetyl-CoA carboxylase (ACC1), and peroxisome proliferator-activated receptor-α (PPARα) in liver were determined by western blotting. The relative expressions of ACC1, fatty acid synthase (FAS), stearoyl-CoA desaturase 1 (SCD1), carnitine palmityl transferase-1 (CPT-1), and SREBP-1 mRNA were detected by qRT-PCR. Results After administering YiQi for three weeks, the levels of fast blood glucose, fasting insulin, TC, TG, LDL, ALT, AST, and ALP were significantly decreased, while HDL significantly increased compared with the model group. YQ could obviously attenuate pancreatic damage and improve islet α- and ß-cell survival compared with the model group. Furthermore, YQ could attenuate hepatic damage caused by lipid accumulation, decrease the content of lipid, and increase the hepatic glycogen content, compared with the model group. In addition, YQ remarkably elevated the proteins expression of p-PI3K, p-AKT, and GLUT4 in pancreas islet and elevated the proteins expression of p-PI3K, p-AKT, GLUT4, p-AMPK, SREBP1, and PPARα and inhibited the expression of p-ACC1 in liver. Besides, YQ reduced the relative expression of ACC1, FAS, SERBP-1c, and SCD mRNA along with the decreased production of CPT-1 mRNA. Conclusions YQ could attenuate type 2 diabetes mellitus by improving islet α- and ß-cells via IRS-2/AKT/GLUT4 pathway and nonalcoholic fatty liver by ameliorating lipid accumulation via AMPK/PPARα/SREBP1/ACC1 pathway.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 80:153376. [PMID: 33086171 DOI: 10.1016/j.phymed.2020.153376] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 09/25/2020] [Accepted: 10/11/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND The utilization of traditional Chinese medicine is a common therapeutic approach for stroke patients in Chinese population, but little is known about the effect of Bu Yang Huan Wu Tang (BYHWT) on post-stroke diabetes. PURPOSE We aimed to evaluate the risk of diabetes in stroke patients who used BYHWT. STUDY DESIGN A retrospective cohort study based on a real-world database was conducted. METHODS Newly diagnosed stroke patients receiving inpatient care from 2000 to 2004 were identified using a large-scale insurance database in Taiwan. Propensity score matching was used to select eligible stroke patients who did (n = 9849) and did not (n = 9849) receive BYHWT. These two groups were followed up until the end of 2009 to track incident diabetes. Cox proportional hazard models were used to calculate the adjusted hazard rations (HRs) and 95% confidence intervals (CIs) for post-stroke diabetes associated with BYHWT during the follow-up period. RESULTS Stroke patients who used BYHWT had a reduced incidence of diabetes (14.1% vs. 19.0%, p < 0.0001) and reduced risk of diabetes (HR 0.77; 95% CI 0.72 to 0.83) compared with the control group. The association between BYHWT and reduced risk of post-stroke diabetes was significant across sexe, age group, and stroke subtype. Additionally, the use of BYHWT was associated with a reduced risk of post-stroke diabetes even after excluding the initial three months of diabetes cases in the sensitivity analysis. CONCLUSIONS Stroke patients who received BYHWT therapy had a reduced risk of diabetes, and a positive effect was observed in various subgroups. However, future clinical trials will be necessary to validate the present findings and identify the biochemical mechanism involved.

Menopausal transition experiences and management strategies of Chinese immigrant women: a scoping review. ACTA ACUST UNITED AC 2020; 27:1434-1443. [PMID: 32769756 DOI: 10.1097/gme.0000000000001623] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
IMPORTANCE AND OBJECTIVE Chinese immigrants are among some of the fastest growing groups in many Western countries, and experience challenges such as language barriers, education gaps, and gender discrimination, which highlights the need for special attention and consideration in Western health care. The purpose of this scoping review is to summarize existing research on the menopausal experiences of Chinese immigrant women (CIW). METHODS This scoping review was written in accordance with PRISMA guidelines. MEDLINE, PsycINFO, CINAHL, AgeLine, ERIC, ProQuest, Nursing and Allied Health Database, PsycARTICLES, Sociology Database, and Education Research Complete were utilized for the literature search. Articles were included if they examined CIW experiencing menopausal transition. A total of 18 studies were included for review. DISCUSSION AND CONCLUSION Findings suggested that CIW experienced a variety of physical symptoms, including muscle and joint pain, urogenital symptoms, vasomotor symptoms, weight gain, decreased physical strength, vision changes, and skin changes. Muscle and joint pain were particularly prevalent and emphasized. CIW also experienced psycho-behavioral symptoms including emotional changes, depression, memory loss, and sexual dysfunction. However, they had a decreased concern regarding symptoms of sexual dysfunction and decreased libido when compared with women from Western cultures. CIW interpreted menopause as a natural aging process involving the next step in life. Cultural expectations of stoicism and silence may cause immigrant women to be less vocal about their menopause experiences and result in feelings of loneliness. Acculturation may be both a facilitator and a barrier to a healthy menopausal transition. CIW were resistant to Western Medicine management such as hormone therapy but were willing to incorporate traditional medicine into their health care. They believed that a healthy mentality was important and used various psychocognitive strategies to maintain a good quality of life. Healthcare providers, researchers, and policymakers need to consider the unique characteristics of CIW's menopausal transition in research, intervention innovation, and practice.

Alkyl Thiourea Functionalised Silica for the Effective Removal of Heavy Metals from Acanthopanax senticosus Extract. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9860425. [PMID: 32309445 PMCID: PMC7136768 DOI: 10.1155/2020/9860425] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 01/16/2020] [Accepted: 01/18/2020] [Indexed: 11/25/2022]
Abstract
Acanthopanax senticosus extract with excessive standard of Pb, Cd, Hg, and Cu was used as the research object, and the alkyl thiourea functionalised silica was used as a new heavy metal removal scavenger. The heavy metal removal process was optimised by orthogonal experiment with dynamic and static adsorption modes. Meanwhile, the content of Acanthopanax B and Acanthopanax E, the solid content, and the HPLC fingerprint similarity were used as quality monitoring indicators of Acanthopanax senticosus heavy metal removal before and after. Then, the technical adaptability of heavy metal removal by alkyl thiourea functionalised silica was evaluated. Under the optimal dynamic adsorption conditions, the average removal rates of Pb, Cd, Hg, and Cu were 91.64%, 93.04%, 81.77%, and 83.11%, respectively. Under the optimal static adsorption conditions, the average removal rates of Pb, Cd, Hg, and Cu were 82.22%, 89.95%, 81.26%, and 82.97%, respectively. During Acanthopanax senticosus extract heavy metal removal before and after, the change percentage of Acanthopanax B and Acanthopanax E was less than 2.00%, the solid content loss rate was only 0.18%, and the fingerprint similarity was over 99.9%. The method can be used to satisfy the high efficiency of selective removal of harmful elements in Acanthopanax senticosus extract and the effective composition of almost no effect; the method is simple and easy, so it can be recommended for pretreatment of heavy metals in Traditional Chinese Medicine extracts, and this way provides a new thought and research technique to decrease the contents of heavy metals.
