Abstract
OBJECTIVES Polyphenol compounds are classified as organic compounds with phenolic units exhibiting a variety of biological functions. This meta-analysis aims to assess the efficacy and safety of polyphenol compounds (curcumin, cranberry, garlic, liquorice and broccoli) in eradicating Helicobacter pylori. DESIGN Systematic review and meta-analysis. METHODS Literature searches were conducted on PubMed, Embase, The Cochrane Library, Web of Science, Medline, Chinese National Knowledge Infrastructure database, Chinese Scientific Journal Database and Wan Fang database from inception to January 2022. All randomised controlled trials comparing polyphenol compounds with the placebo or used as an adjunct treatment are included in this meta-analysis.The treatment effect for dichotomous outcomes was assessed using risk ratio (RR), while for continuous outcomes, mean differences both with 95% CIs, were used. Subgroup analyses were carried out for different treatment schemes and polyphenol compound species. RESULTS 12 trials were included in the meta-analysis. The total eradication rate of H.pylori in the polyphenol compounds group was higher than in the group without polyphenol compounds. Statistical significance was also observed (RR 1.19, 95% CI 1.03 to 1.38, p=0.02). The most frequent adverse effects of polyphenol compounds included diarrhoea, headache and vomiting. However, there were no differences regarding side effects between the two groups (RR 1.47, 95% CI 0.83 to 2.58, p=0.18). In subgroup analyses, the H.pylori eradication rate regimens with polyphenols therapy was superior to that of regimens without polyphenols therapy in the polyphenols versus placebo subgroup (RR 4.23, 95% CI 1.38 to 12.95, p=0.01), polyphenols plus triple therapy versus triple therapy subgroup (RR 1.11, 95% CI 1.01 to 1.22, p=0.03). CONCLUSION Polyphenol compounds can improve H.pylori eradication rates. Polyphenol compounds plus standard triple therapy can significantly improve the eradication. However, no evidence of a higher incidence of side effects could be found. PROSPERO REGISTRATION NUMBER CRD42022307477.

Abstract
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), like phenylbutazone (PBZ), are prescribed to treat pain and inflammation in the equine. However, experimentally their use has been associated with the development of Equine Glandular Gastric Disease (EGGD). To evaluate the prophylactic effects of Glycyrrhiza glabra root extracts (GGRE) on EGGD induction following oral administration of PBZ, 12 donkeys were used. Animals were divided into three equal groups (A, B and C) in a randomized block design. A: placebo, B: PBZ (4.4 mg/kg PO q 12 h) and C: PBZ plus GGRE (17.6 mg/kg PO q 24h). Gastroscopy and blood sampling for CBC, biochemical tests and antioxidant status were performed days 0 and 7. All but 1 animal had no EGGD lesions on day 0, but on day 7, severe EGGD lesions were seen in group B animals (grade 1/4 (× 1), grade 2/4 (× 2), and grade 3/4 (× 1)). Only mild changes were seen in group C animals, the most severe lesions being grade 1/4 lesions in 2 animals. No change was observed in Group A. Hematology and serum antioxidant status did not change significantly in any group. In group B glucose decreased and ALT and ALP increased, while in group C only ALP increased. In conclusion, GGRE reduced the severity of EGGD caused by PBZ. Further, GGRE prevented PBZ induced hypoglycemia and might reduce the possible hepatic injury of PBZ.

Abstract
Antibiotic-resistant Helicobacter pylori isolates have become a global concern. The standard triple or quadruple therapies have recently become the most effective protocol for eradicating H. pylori in the gastrointestinal tract. There is evidence regarding the impact of different complementary or dietary supplements on H. pylori eradication. This review article intended to search electronic bibliographic databases for any clinical studies that evaluated the use of any herbal or dietary supplements to eradicate H. pylori up to June 2021. A total of 20 human studies met our criteria and were reviewed. Although some herbal medicines have shown their efficacy and safety in eradicating H. pylori in different clinical trials, more randomized blind, placebo-controlled human trials with a large sample size must be performed to extend our knowledge.

Abstract
BACKGROUND Helicobacter pylori-associated gastritis (HPAG) is a common digestive system disease that its therapeutic goal is to eradicate Helicobacter pylori. However, due to the widespread use of antibiotics, problems for example, antibiotic resistance, reinfection, and gastrointestinal side effects have emerged. The solution of above problems provides a broad space for traditional Chinese medicine (TCM) to exert its remarkable advantages on the treatment of HPAG. METHODS Extensive database retrieval using platforms not limited to but including Web of Science, SpringerLink, ScienceDirect, Google Scholar, China National Knowledge Infrastructure, Wanfang, and VIP database was performed using keywords such as "Helicobacter pylori-associated gastritis" or "HPAG" or "Helicobacter pylori" or "H. pylori" or "gastritis" and "traditional Chinese medicine" or "TCM" or "herbs" or "Chinese herbal medicine". In addition, related books, PhD, and master's dissertations were also researched to provide a comprehensive review. RESULTS This review mainly introduces the clinical efficacy of TCM formulas for HPAG, as well as active ingredient and pharmacological mechanisms of herbs. What's more, this review puts forward potential prospects for future research. CONCLUSION These research works have shown the therapeutic benefits of TCM in the treatment of HPAG. The development of TCM with more specific functions and practical data will not only become a significant trend in the world market but also have an irreplaceable role in the future treatment of HPAG. More continued researches should be undertaken in the future.

Bioactive Candy: Effects of Licorice on the Cardiovascular System. Foods 2019; 8:foods8100495.

Abstract
Licorice, today chiefly utilized as a flavoring additive in tea, tobacco and candy, is one of the oldest used herbs for medicinal purposes and consists of up to 300 active compounds. The main active constituent of licorice is the prodrug glycyrrhizin, which is successively converted to 3β-monoglucuronyl-18β-glycyrrhetinic acid (3MGA) and 18β-glycyrrhetinic acid (GA) in the intestines. Despite many reported health benefits, 3MGA and GA inhibit the 11-β-hydrogenase type II enzyme (11β-HSD2) oxidizing cortisol to cortisone. Through activation of mineralocorticoid receptors, high cortisol levels induce a mild form of apparent mineralocorticoid excess in the kidney and increase systemic vascular resistance. Continuous inhibition of 11β-HSD2 related to excess licorice consumption will create a state of hypernatremia, hypokalemia and increased fluid volume, which can cause serious life-threatening complications especially in patients already suffering from cardiovascular diseases. Two recent meta-analyses of 18 and 26 studies investigating the correlation between licorice intake and blood pressure revealed statistically significant increases both in systolic (5.45 mmHg) and in diastolic blood pressure (3.19/1.74 mmHg). This review summarizes and evaluates current literature about the acute and chronic effects of licorice ingestion on the cardiovascular system with special focus on blood pressure. Starting from the molecular actions of licorice (metabolites) inside the cells, it describes how licorice intake is affecting the human body and shows the boundaries between the health benefits of licorice and possible harmful effects.

Abstract
Licorice is a popular sweetener and a thirst quencher in many food products particularly in Europe and the Middle East and also one of the oldest and most frequently used herbs in traditional Chinese medicine. As a wide application of food additive, it is necessary to clarify bioactive chemical ingredients and the mechanism of action of licorice. In this study, a network pharmacology approach that integrated drug-likeness evaluation, structural similarity analysis, target identification, network analysis, and KEGG pathway analysis was established to elucidate the potential molecular mechanism of licorice. First, we collected and evaluated structural information of 282 compounds in licorice and found 181 compounds that met oral drug rules. Then, structural similarity analysis with known ligands of targets in the ChEMBL database (similarity threshold = 0.8) was applied to the initial target identification, which found 63 compounds in licorice had 86 multi-targets. Further, molecular docking was performed to study their binding modes and interactions, which screened out 49 targets. Finally, 17 enriched KEGG pathways (p < 0.01) of licorice were obtained, exhibiting a variety of biological activities. Overall, this study provided a feasible and accurate approach to explore the safe and effective application of licorice as a food additive and herb medicine.

Abstract
Primary dysmenorrhea is a common gynecological disorder in women of reproductive age. Despite the effective conventional treatments such as nonsteroidal anti-inflammatory drugs and oral contraceptives, researchers have always been looking for alternative drugs due to the adverse effects and limited efficacy of these medications. Glycyrrhiza glabra L. (G. glabra), commonly known as Licorice, has been applied for a long time as a plant with multiple therapeutic potencies in Traditional Persian Medicine (TPM). This study was designed to evaluate the effect of the G. glabra on primary dysmenorrhea. Sixty patients with moderate and severe dysmenorrhea were randomly divided into two groups; one group received 400 mg Ibuprofen tablets every 8 h and placebo syrup and the other received 5 cc of G. glabra syrup two times a day and placebo tablets. The patients took the drugs from the first day of menstruation to fifth for two consequent cycles. The primary pain intensity and its changes were evaluated in each group and compared between two groups. The reduction of pain intensity was 5.85 (±3.11) in the G. glabra group compared with 6.92 (±1.87) in the Ibuprofen group (p < 0.001). No significant difference detected between the two groups (p = 0.151). No serious side effects were reported during the study. This study suggests that we can use G. glabra to relieve pain in the patients with primary dysmenorrhea; although studies with a larger sample size may lead to more comprehensive perceptions about the efficacy of G. glabra.

Abstract
Sub-3 nm ultrasmall Bi2Se3 nanodots stabilized with bovine serum albumin were successfully synthesized through a reaction of hydroxyethylthioselenide with bismuth chloride in aqueous solution under ambient conditions. These nanodots exhibit a high photothermal conversion efficiency (η = 50.7%) due to their strong broad absorbance in the near-infrared (NIR) window and serve as a nanotheranostic agent for photoacoustic imaging and photothermal cancer therapy. In addition, they also display radioenhancement with a ratio of 6% due to their sensitivity to X-rays, which makes them a potential sensitizer for radiotherapy. These nanodots were also labled with radioactive 99mTc for quantification of their biodistribution by single-photon-emission computed tomography (SPECT)/computed tomography (CT) imaging. Our work demonstrates the potential of ultrasmall Bi2Se3 nanodots in multimodal imaging-guided synergetic radiophotothermal therapy of cancer.

Abstract
Objective The aim of this study was to evaluate the effect of licorice in H. pylori eradication in patients suffering from dyspepsia either with peptic ulcer disease (PUD) or non-ulcer dyspepsia (NUD) in comparison to the clarithromycin-based standard triple regimen. Methods In this randomized controlled clinical trial, 120 patients who had positive rapid urease test were included and assigned to two treatment groups: control group that received a clarithromycin-based triple regimen, and study group that received licorice in addition to the clarithromycin-based regimen for two weeks. H. pylori eradication was assessed six weeks after therapy. Data was analyzed by chi-square and t-test with SPSS 16 software. Results Mean ages and SD were 38.8 ± 10.9 and 40.1 ± 10.4 for the study and control groups, respectively, statistically similar. Peptic ulcer was found in 30% of both groups. Response to treatment was 83.3% and 62.5% in the study and control groups, respectively. This difference was statistically significant. Conclusion Addition of licorice to the triple clarithromycin-based regimen increases H. pylori eradication, especially in the presence of peptic ulcer disease.
