Abstract
Chronic gastritis (CG) is a persistent inflammation of the gastric mucosa that can cause uncomfortable symptoms in patients. Traditional Chinese medicine (TCM) has been widely used to treat CG due to its precise efficacy, minimal side effects, and holistic approach. Clinical studies have confirmed the effectiveness of TCM in treating CG, although the mechanisms underlying this treatment have not yet been fully elucidated. In this review, we summarized the clinical research and mechanisms of TCM used to treat CG. Studies have shown that TCM mechanisms for CG treatment include H. pylori eradication, anti-inflammatory effects, immune modulation, regulation of gastric mucosal cell proliferation, apoptosis, and autophagy levels.

Abstract
PURPOSE Helicobacter pylori (H. pylori) positive peptic ulcer disease (PUD) is a highly prevalent digestive disease with serious consequences of poor prognosis without rational medical intervention. Apparent advantages of Chinese herbal formulae application in PUDs have been appreciated by clinical practitioners recently in China. However, there is no enough viewpoint of evidence-based medicine for them to reach a broad consensus at the more favorable formulae. Therefore, we adopted the method of Bayesian network Meta-analysis (BNMA) in order to get a solution. METHOD Literature retrieval of clinical randomized controlled trials (RCTs) was conducted with eight databases of PubMed, Embase, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, the VIP medicine information system, the Wanfang Data Knowledge Service Platform and Chinese Biomedical Literature Service System. Review Manager 5.4 software, R project 4.1.1 software and STATA16.0 software were used to carry out this BNMA. The primary outcome indicator is H. pylori eradicated rate. The secondary outcome indicator is clinical effectiveness rate, recurrence rate and adverse reaction report. RESULT A total of fifty-one RCTs involving 5172 patients and ten therapeutic strategies were included in this BNMA. The results showed that supplementation with Chinese herbal formulae significantly improved the eradication rate, clinical efficiency and reduced recurrence rate of H. pylori compared with the single conventional triple therapy (CON) group in a relatively safe manner. Comprehensive therapeutic efficacy analysis of H. pylori eradicated rate and clinical effectiveness rate showed that CON combined with Xiangsha Liujunzi decoction (XSD) manifests at the first grade among these ten therapeutic strategies. CONCLUSION The efficacy and safety of Chinese herbal formulae and conventional triple therapy were validated by this BNMA. CON+XSD appears to be the most satisfactory therapeutic strategy for H. pylori-positive PUD, reminding clinicians of the potential value of the combination of Chinese herbal formulae and conventional chemotherapy.

[PMID: 36147839 PMCID: PMC9485998 DOI: 10.3389/fmicb.2022.962354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 08/15/2022] [Indexed: 11/21/2022] Open
Abstract
Background Helicobacter pylori (H. pylori) infects half of the human population globally. Eradication rates with triple or quadruple therapy have decreased owing to the increasing rate of antibiotic resistance. Jinghua Weikang capsule (JWC) is the first and most popular Chinese patent medicine approved by the state for the treatment of gastritis and peptic ulcers caused by H. pylori infection in China. Previous studies have found that JWC has a certain bactericidal effect on drug-resistant H. pylori and its major component, Chenopodium ambrosioides L. inhibits biofilm formation, but the mechanism remains unclear. This study focused on drug-resistant H. pylori and explored whether JWC could reverse drug resistance and its related mechanisms. Method The agar plate dilution method, E-test method, and killing kinetics assay were used to evaluate the bactericidal effect of JWC on antibiotic-resistant H. pylori and its effect on antibiotic resistance. Sanger sequencing was used to detect mutations in drug resistance genes. The crystal violet method, scanning electron microscopy, and confocal laser scanning microscopy were used to evaluate the effects of JWC on biofilms. qPCR was performed to evaluate the effect of JWC on the expression of efflux pump-related genes. qPCR and immunofluorescence were used to evaluate the effects of JWC on H. pylori adhesion. Results JWC showed considerable antibacterial activity against drug-resistant H. pylori strains, with minimum inhibitory concentration (MIC) values ranging from 64 to 1,024 μg/ml. The MIC of metronidazole (MTZ) against H. pylori 26,695–16R decreased from 64 to 6 μg/ml after treatment with 1/2 MIC of JWC. The resistance of H. pylori 26,695–16R to MTZ was reversed by JWC, and its effect was better than that of PaβN and CCCP. H. pylori 26,695–16R is a moderate biofilm-forming strain, and JWC (16–64 μg/ml) can inhibit the formation of biofilms in H. pylori 26,695–16R. JWC reduced the expression of HP0605-HP0607 (hefABC), HP0971-HP0969 (hefDEF), HP1327-HP1329 (hefGHI), and HP1489-HP1487. JWC reduced the adhesion of H. pylori to GES-1 cells and the expression of adhesives NapA, SabA, and BabA. Conclusion The reversal of MTZ resistance by JWC may be achieved through the adhesin/efflux pump-biofilm pathway.

Abstract
This study was aimed at evaluating the efficacy of traditional Chinese medicine (TCM) in the adjuvant treatment of Helicobacter pylori-associated gastritis (HPAG) and exploring the molecular mechanism underlying the action of the basic TCM compounds against HPAG. Eight representative Chinese and British databases were combed for pertinent literature. In light of the basic principle of evidence-based medicine, this work rigorously stuck to the inclusion and exclusion of criteria so as to plump for qualified articles. Also, the data mining method was adopted to help determine the basic TCM compound for HPAG treatment. Furthermore, a network pharmacology-based strategy was used to uncover the underlying mechanisms of the basic TCM compound against HPAG. Ultimately, molecular docking was used for preliminary verification. TCM combined with triple or quadruple therapy against HPAG possessed more advantages in improving the total effective rate and H. pylori eradication rate than triple or quadruple therapy alone. The basic TCM plant materials against HPAG consisted of Citrus reticulata Blanco, Glycyrrhiza uralensis Fisch, Pinellia ternata (Thunb.) Breit, Coptis chinensis Franch, and Poria cocos (Schw.) Wolf. Quercetin, kaempferol, naringenin, baicalein, nobiletin, and hederagenin were determined as the key active ingredients of the basic TCM preparation against HPAG. Moreover, these ingredients played a therapeutic role by acting on AKT1, TP53, interleukin (IL)-6, VEGFA, CASP3, MAPK3, JUN, TNF, and MAPK8 via Pathways in cancer, PI3K-Akt signaling pathway, TNF signaling pathway, and MAPK signaling pathway. The results of molecular docking indicated that the key ingredients could bind stably with the core targets. The efficacy of the TCM in the adjuvant treatment of HPAG is worthy of affirmation. Compatible use of the key ingredients of the basic TCM compound is a novel idea of drug research with profound clinical significance and research value in the development of anti- H. pylori drugs.

Abstract
We evaluated the leaf essential oil in whole or fractions of Dysphania ambrosioides with respect to their resistance to wood decay fungal activities in vitro of 4 fungi. The main ingredients with the greater anti-wood decay capability were also identified. Fresh leaves of D. ambrosioides were hydrodistillated in a Clevenger-type apparatus and the resulting oil characterized using GC-FID and GC-MS instruments. The essential oil was found to consist of α-terpinene (30.5%), p-cymene (17.3%), carvacrol (16.2%), and ascaridole (15.1%). The oil showed resistance to wood decay activity of Trametes versicolor, Phanerochaete chrysosporium, Phaeolus schweinitzii, and Lenzites sulphureu. The oil had excellent resistance to wood decay fungal activities, and the active compounds were shown to be carvacrol and ascaridole.

Abstract
Nonsteroidal anti-inflammatory drug-induced small bowel injuries (NSIs) have been largely ignored for decades due to the focus on nonsteroidal anti-inflammatory drug gastropathy. With the visualization of the small intestines enabled by video capsule endoscopy, the frequency and severity of NSIs have become more evident. NSIs have a complex pathophysiology, and no effective preventive or treatment options have been proven. Complementary and alternative medicine (CAM) has been used to treat disorders of the small intestine, and more research on its effectiveness for NSIs has been conducted.We reviewed the current evidence and mechanisms of action of CAMs on NSI. Clinical and experimental studies on the effect of CAMs on NSIs were performed using 10 databases.Twenty-two studies (3 clinical and 19 in vivo experimental studies) were included in the final analysis involving 10 kinds of CAMs: bovine colostrum, Orengedokuto (coptis), muscovite, licorice, grape seed, wheat, brown seaweed, Ganoderma lucidum fungus mycelia, Chaenomeles speciosa (sweet) Nakai (muguasantie), and Jinghua Weikang capsule. The mechanisms of CAM include an increase in prostaglandin E2, reparation of the enteric nervous system, inhibition of pro-inflammatory cytokines, reduction of intestinal permeability and enteric bacterial numbers, decrease in oxidative stress, and modulation of small intestinal motility.CAM may be a novel alternative option for treating and preventing NSI, and further studies on human and animal models with relevant comorbidities are warranted.

Abstract
Gastric precancerous lesions (GPLs) are an essential precursor in the occurrence and development of gastric cancer, known to be one of the most common and lethal cancers worldwide. Traditional Chinese medicine (TCM) has a positive prospect for the prevention and therapy of GPL owing to several advantages including a definite curative effect, fewer side effects compared to other treatments, multiple components, and holistic regulation. Despite these characteristic advantages, the mechanisms of TCM in treating GPL have not been fully elucidated. In this review, we summarize the current knowledge with respect to herbal formulations and the therapeutic mechanisms of TCM active ingredients for GPL. This paper elaborates on the mechanisms of TCM underlying the prevention and treatment of GPL, specifically those that are linked to anti-H. pylori, anti-inflammation, antiproliferation, proapoptotic, antioxidation, antiglycolytic, and antiangiogenesis effects.

Abstract
Infectious diseases caused by pathogenic bacteria seriously threaten human lives. Although antibiotic therapy is effective in the treatment of bacterial infections, the overuse of antibiotics has led to an increased risk of antibiotic resistance, putting forward urgent requirements for novel antibacterial drugs. Traditional Chinese herbal medicine (TCHM) and its constituents are considered to be potential sources of new antimicrobial agents. Currently, a series of chemical compounds purified from TCHM have been reported to fight against infections by drug-resistant bacteria. In this review, we summarized the recent findings on TCHM-derived compounds treating drug-resistant bacterial infections. Further studies are still needed for the discovery of potential antibacterial components from TCHM.

Abstract
Helicobacter pylori (H. pylori) treatment requires the development of more effective therapies, mainly owing to the challenges posed by the bacterial resistance to antibiotics. In China, critically high infection and antibiotic resistance rates have limited the application of classic H. pylori eradication therapies. Consequently, researchers are attempting to find new solutions by drawing from traditional medicine. This article reviews basic scientific and clinical progress in the use of integrated Chinese and Western medicine (IM) to treat H. pylori; describes the conflicting results between in vivo and in vitro studies in this regard; discusses the observed clinical effects of IM, with emphasis on traditional patent medicines; and proposes a role for IM in both the diagnosis and treatment of H. pylori, including the use of tongue manifestation as an early diagnostic method and capitalizing on IM's direct and indirect methods for enhancing antibiotic effect.

Abstract
The antileishmanial activity of the essential oil (EO) from Chenopodium ambrosioides L. has been demonstrated in vitro and in animal models, attributed to the major components of the EO. This study focused on the effects of the three major EO compounds carvacrol, caryophyllene oxide (Caryo), and the antileishmanial endoperoxide ascaridole (Asc) on mitochondrial functions in Leishmania tarentolae promastigotes (LtP). EO and Caryo were able to partially inhibit the leishmanial electron transport chain, whereas other components failed to demonstrate a direct immediate effect. Caryo demonstrated inhibition of complex III activity in LtP and in isolated complex III from other species. The formation of superoxide radicals was studied in Leishmania by electron spin resonance spectroscopy in the presence of iron chelators wherein selected compounds failed to trigger a significant immediate additional superoxide production in LtP. However, upon prolonged incubation of Leishmania with Asc and especially in the absence of iron chelators (allowing the activation of Asc), an increased superoxide radical production and significant impairment of mitochondrial coupling in Leishmania was observed. Prolonged incubation with all EO components resulted in thiol depletion. Taken together, the major components of EO mediate their leishmanicidal activity via different mitochondrial targets and time profiles. Further studies are required to elucidate possible synergistic effects of carvacrol and Asc and the influence of minor compounds.

Abstract
AIM: To investigate the bactericidal effects of Chenopodium ambrosioides L. (CAL) against Helicobacter pylori (H. pylori) both in vitro and in vivo.
METHODS: For in vitro experiments, the inhibitory activity of CAL was tested using an agar dilution method; H. pylori strain NCTC11637 was incubated on Columbia blood agar plates containing serial concentrations of CAL. The minimal inhibitory concentration (MIC) was determined by the absence of H. pylori colonies on the agar plate. Time-kill curves were used to evaluate bactericidal activity; the average number of colonies was calculated at 0, 2, 8 and 24 h after liquid incubation with concentrations of CAL at 0.5, 1, and 2 × MIC. For in vivo experiments, H. pylori-infected mice were randomly divided into CAL, triple therapy (lansoprazole, metronidazole, and clarithromycin), blank control, or H. pylori control groups. The eradication ratios were determined by positive findings from rapid urease tests (RUTs) and by histopathology.
RESULTS: In vitro, the MIC of CAL against H. pylori was 16 mg/L. The time-kill curves showed a stable and persistent decreasing tendency with increasing CAL concentration, and the intensity of the bactericidal effect was proportional to dose; the 1 and 2 × MIC completely inhibited the growth of H. pylori at 24 h. In vivo, the eradication ratios in the CAL group were 60% (6/10) by RUT and 50% (5/10) by histopathology. Ratios in the triple therapy group were both 70% (7/10), and there was no difference between the CAL and triple therapy groups. Histopathologic evaluation revealed massive bacterial colonization on the surface of gastric mucosa and slight infiltration of mononuclear cells after inoculation with H. pylori, but no obvious inflammation or other pathologic changes in gastric mucosa of mice from CAL and triple therapy groups.
CONCLUSION: CAL demonstrates effective bactericidal activity against H. pylori both in vitro and in vivo.

Abstract
Peptic ulcer disease continues to be issue especially due to its high prevalence in the developing world. Helicobacter pylori (H. pylori) infection associated duodenal ulcers should undergo eradication therapy. There are many regimens offered for H. pylori eradication which include triple, quadruple, or sequential therapy regimens. The central aim of this systematic review is to evaluate the evidence for H. pylori therapy from a meta-analytical outlook. The consequence of the dose, type of proton-pump inhibitor, and the length of the treatment will be debated. The most important risk factor for eradication failure is resistance to clarithromycin and metronidazole.

Abstract
Helicobacter pylori (H. pylori) successfully colonizes the human stomach of the majority of the human population. This infection always causes chronic gastritis, but may evolve to serious outcomes, such as peptic ulcer, gastric carcinoma or mucosa-associated lymphoid tissue lymphoma. H. pylori first line therapy recommended by the Maastricht-4 Consensus Report comprises the use of two antibiotics and a proton-pomp inhibitor, but in some regions failure associated with this treatment is already undesirable high. Indeed, treatment failure is one of the major problems associated with H. pylori infection and is mainly associated with bacterial antibiotic resistance. In order to counteract this situation, some effort has been allocated during the last years in the investigation of therapeutic alternatives beyond antibiotics. These include vaccines, probiotics, photodynamic inactivation and phage therapy, which are briefly revisited in this review. A particular focus on phytomedicine, also described as herbal therapy and botanical therapy, which consists in the use of plant extracts for medicinal purposes, is specifically addressed, namely considering its history, category of performed studies, tested compounds, active principle and mode of action. The herbs already experienced are highly diverse and usually selected from products with a long history of employment against diseases associated with H. pylori infection from each country own folk medicine. The studies demonstrated that many phytomedicine products have an anti-H. pylori activity and gastroprotective action. Although the mechanism of action is far from being completely understood, current knowledge correlates the beneficial action of herbs with inhibition of essential H. pylori enzymes, modulation of the host immune system and with attenuation of inflammation.
