Abstract
Methotrexate (MTX) is recognized as the golden standard for rheumatoid arthritis (RA) treatment. However, it can cause liver damage in long-term application. Although nanomedicines can target to inflamed sites, most of them tend to accumulate in liver. Glycyrrhizinic acid (GA) holds potential to reverse MTX-associated hepatotoxicity. The combination of GA and MTX might achieve a synergistic anti-inflammatory efficacy and reduced hepatotoxicity. As MTX and GA have totally different in vivo performance, it is necessary to co-encapsulate them in one carrier to coordinate their in vivo fates. Here, we co-delivered MTX and GA to arthritic joints using a human serum albumin-based nanoparticle (HSN). We found the dual drug-loaded albumin nanoparticles (HSN/MTX/GA) could preferentially distribute in inflamed joints, where GA can extend MTX retention by inhibiting the expression of efflux pumps for MTX, thereby exerting synergistic therapeutic effect. In liver tissues, GA was able to reverse the MTX-induced liver damage by activating anti-oxidant defense Nrf2/HO-1 and anti-apoptosis Bcl-2/Bax signaling. We offer a combinational strategy to effectively overcome the MTX-induced hepatotoxicity and enhance the anti-rheumatic efficacy simultaneously. Furthermore, we verified the underlying mechanism about how GA cooperated with MTX in vivo for the first time. Our findings can provide valuable insights for long-term treatment of RA.

Abstract
CONTEXT Desloratadine, an H1 receptor antagonist, is suggested as an effective first-line drug for chronic urticarial (CU). However, the efficacy of desloratadine alone is limited, and the recurrence rate of CU is relatively high. OBJECTIVE We sought to evaluate the efficacy and clinical feasibility of desloratadine in combination with compound glycyrrhizin in the treatment of CU. MATERIALS AND METHODS A systematic literature search was conducted in the databases of the China National Knowledge Infrastructure Database, VIP, WanFang, PubMed, and Web of Science using subject terms: "Chronic urticaria", "Loratadine", and "Compound glycyrrhizin". Randomised controlled trials (RCTs) that compared the efficiency and safety of the combination treatment with desloratadine alone starting from January 1, 2014 until February 10, 2021 were selected by two co-first authors independently, and the extracted data were analysed using Rev Man 5.3 software. RESULTS Fourteen RCTs were included in our meta-analysis with a total of 1501 patients. The results showed that the combination treatment yielded a better treatment effect (total response rate: RR = 1.23, 95% CI: 1.17 to 1.29, p < 0.00001; cure rate: RR = 1.50, 95% CI: 1.30 to 1.73, p < 0.00001), lower recurrence rate as well as superior immune improvement than the treatment with desloratadine alone. In addition, there was no significant difference in the safety of the two treatments. DISCUSSION AND CONCLUSION The combination of desloratadine and compound glycyrrhizin is a promising treatment for CU and is associated with decreased serum IgE level and improved proportions of CD4+ T and CD8+ T cells.

Abstract
Angiotensin converting enzyme 2 (ACE2) is a key entry point of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus known to induce Coronavirus disease 2019 (COVID-19). We have recently outlined a concept to reduce ACE2 expression by the administration of glycyrrhizin, a component of Glycyrrhiza glabra extract, via its inhibitory activity on 11beta hydroxysteroid dehydrogenase type 2 (11betaHSD2) and resulting activation of mineralocorticoid receptor (MR). We hypothesized that in organs such as the ileum, which co-express 11betaHSD2, MR and ACE2, the expression of ACE2 would be suppressed. We studied organ tissues from an experiment originally designed to address the effects of Glycyrrhiza glabra extract on stress response. Male Sprague Dawley rats were left undisturbed or exposed to chronic mild stress for five weeks. For the last two weeks, animals continued with a placebo diet or received a diet containing extract of Glycyrrhiza glabra root at a dose of 150 mg/kg of body weight/day. Quantitative PCR measurements showed a significant decrease in gene expression of ACE2 in the small intestine of rats fed with diet containing Glycyrrhiza glabra extract. This effect was independent of the stress condition and failed to be observed in non-target tissues, namely the heart and the brain cortex. In the small intestine we also confirmed the reduction of ACE2 at the protein level. Present findings provide evidence to support the hypothesis that Glycyrrhiza glabra extract may reduce an entry point of SARS-CoV-2. Whether this phenomenon, when confirmed in additional studies, is linked to the susceptibility of cells to the virus requires further studies.

Abstract
OBJECTIVE Coronavirus disease 2019 (COVID-19) is a fatal and fast-spreading viral infection. To date, the number of COVID-19 patients worldwide has crossed over six million with over three hundred and seventy thousand deaths (according to the data from World Health Organization; updated on 2 June 2020). Although COVID-19 can be rapidly diagnosed, efficient clinical treatment of COVID-19 remains unavailable, resulting in high fatality. Some clinical trials have identified vitamin C (VC) as a potent compound pneumonia management. In addition, glycyrrhizic acid (GA) is clinically as an anti-inflammatory medicine against pneumonia-induced inflammatory stress. We hypothesized that the combination of VC and GA is a potential option for treating COVID-19. METHODS The aim of this study was to determine pharmacological targets and molecular mechanisms of VC + GA treatment for COVID-19, using bioinformational network pharmacology. RESULTS We uncovered optimal targets, biological processes and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of VC + GA against COVID-19. Our findings suggested that combinatorial VC and GA treatment for COVID-19 was associated with elevation of immunity and suppression of inflammatory stress, including activation of the T cell receptor signaling pathway, regulation of Fc gamma R-mediated phagocytosis, ErbB signaling pathway and vascular endothelial growth factor signaling pathway. We also identified 17 core targets of VC + GA, which suggest as antimicrobial function. CONCLUSIONS For the first time, our study uncovered the pharmacological mechanism underlying combined VC and GA treatment for COVID-19. These results should benefit efforts to address the most pressing problem currently facing the world.

Abstract
Context: Both nobiletin (NBL) and glycyrrhizin (GL) have anti-inflammatory and antitumor properties. These agents may be co-administered in the clinic. However, the drug-drug interaction between them is not clear.Objective: The drug-drug interaction between GL and NBL was investigated, to clarify the effect of GL on the pharmacokinetics of NBL, and its main mechanism.Materials and methods: The pharmacokinetic profiles of oral administration of NBL (50 mg/kg) in Sprague-Dawley rats of two groups with six each, with or without pre-treatment of GL (100 mg/kg/day for 7 days), were investigated. The effects of GL on the metabolic stability and transport of NBL were also investigated through the rat liver microsome and Caco-2 cell transwell models.Results: The results showed that GL significantly decreased the peak plasma concentration (from 1.74 ± 0.15 to 1.12 ± 0.10 μg/mL) and the t1/2 (7.44 ± 0.65 vs. 5.92 ± 0.68) of NBL, and the intrinsic clearance rate of NBL was increased by the pre-treatment with GL (39.49 ± 2.5 vs. 48.29 ± 3.4 μL/min/mg protein). The Caco-2 cell transwell experiments indicated that GL could increase the efflux ratio of NBL from 1.61 to 2.41.Discussion and conclusion: These results indicated that GL could change the pharmacokinetic profile of NBL, via increasing the metabolism and efflux of NBL in rats. It also suggested that the dose of NBL should be adjusted when co-administrated with GL in the clinic.

Abstract
INTRODUCTION Pyoderma gangrenosum (PG) is a phenomenon of cutaneous ulceration with unknown etiology. About half the cases have associated extracutaneous manifestations or associated systemic diseases. The most commonly associated systemic disorders include inflammatory bowel disease (IBD), hematologic malignancies, autoimmune arthritis, and vasculitis. This is a case report about giant PG with ulcerative colitis (UC), which is extremely rare. CASE PRESENTATION A 39-year-old female farmer with UC for the past 3 years presented with multiple painful ulcers, erosion, exudation, and crusting on the right leg for 1 month. A cutaneous examination showed diffusely distributed, multiple, well-defined, deep purulent ulcers on the right medial shank measuring 6 to 20 cm and sporadic worm-eaten ulceration on the right ectocnemial, with severe oozing and erosions. The ulcerations exhibited deep undermined borders, granulated tissue and a black eschar at the base. The right shank and feet were severely swollen, restricting movement. The arteria dorsalis pedis pulse was good, with normal sensation on the skin of the right shank and feet. Laboratory examinations showed a white cell count of 11.8 × 109/L, hemoglobin was 91 g/L, erythrocyte sedimentation rate was 82 mm/h, unelevated procalcitonin, serum C-reactive protein was 131.29 mg/L, and a negative tuberculin skin test. Enteroscopy demonstrated endoscopic evidence of UC. A skin lesion biopsy showed superficial erosion and scarring. Partial epidermal hyperplasia, partial epidermal atrophy and thinning, mild edema of the dermal papill. Most of the middle and lower part of the dermis, showed dense lymphocytes, histiocytes, multinucleated giant cells, and neutrophil infiltration. PG with UC was diagnosed based on clinical manifestations, laboratory examinations and enteroscopy results. INTERVENTIONS She was treated with topical applications of povidone iodine and kangfuxin solution twice daily, methylprednisolone sodium succinate 40 mg and compound glycyrrhizin 60 mg via intravenous drip once a day, along with thalidomide 50 mg twice daily. The UC was controlled with mesalazine. OUTCOMES She required multiple therapies to achieve PG healing 3 months later. No PG recurrence was observed during the 1-year follow-up. CONCLUSION Recognizing the clinical features of PG and its pathogenic nature, ensuring timely management fundamental for preventing severe destruction and deformity, and control of associated diseases are important aspects of treatment. Combination therapy is essential for PG patients with IBD.

Abstract
RATIONALE Methotrexate (MTX) is an antimetabolite of folic acid, which is used for management of ectopic pregnancy. MTX-related toxicity may include cutaneous mucosal damage, bone marrow suppression, gastrointestinal disorders (gastritis, diarrhea, hematitis), liver and kidney function damage, pulmonary toxicity, cardiac toxicity, and nerve toxicity. However, it is not usual for vulvar edema induced by low-dose methotrexate. PATIENT CONCERNS In this case report, we described a patient with severe vulvar edema and oral cavity ulceration and scalp ulceration induced by low-dose MTX treatment for ectopic pregnancy. Her presenting complaints were pain in the vulva, oral cavity, and scalp. DIAGNOSES The patient was diagnosed based on clinical findings for MTX toxic reactions. INTERVENTIONS Vulva was disinfectioned with iodide and Kangfuxin solution, her mouth was rinsed with mouthwash. Three compound glycyrrhizin tablets were orally administered (3 times/day). After 10 days, the broken skin and mucous membrane healed. OUTCOMES The vulvar edema and oral cavity ulceration and scalp ulceration healed. LESSONS Our study demonstrated that even low-dose MTX can be induced skin and mucosal injury, patients and doctors should timely detection of drug toxicity reactions, immediately rescue, prompt discontinuation of medication, and symptomatic treatment to avoid accidental occurrence.

Abstract
The object of the study was to estimate the long-lasting effects induced by ammonium glycyrrhizinate (AG) after a single administration in mice using animal models of pain and inflammation together with biochemical and docking studies. A single intraperitoneal injection of AG was able to produce anti-inflammatory effects in zymosan-induced paw edema and peritonitis. Moreover, in several animal models of pain, such as the writhing test, the formalin test, and hyperalgesia induced by zymosan, AG administered 24 h before the tests was able to induce a strong antinociceptive effect. Molecular docking studies revealed that AG possesses higher affinity for microsomal prostaglandin E synthase type-2 compared to type-1, whereas it seems to locate better in the binding pocket of cyclooxygenase (COX)-2 compared to COX-1. These results demonstrated that AG induced anti-inflammatory and antinociceptive effects until 24-48 h after a single administration thanks to its ability to bind the COX/mPGEs pathway. Taken together, all these findings highlight the potential use of AG for clinical treatment of pain and/or inflammatory-related diseases.

Abstract
The article presents a theoretical generalization of the research results the effectiveness of heparisin on the state of the carbohydrate-protein components of the extracellular matrix of connective tissue in liver in patients with non-alcoholic steatohepatitis with obesity I-II degree and chronic kidney disease І-ІІ stage. The purpose of the study is to find out the effectiveness of heparisin (glycyrizine 40 mg, glycine 400 mg, L-cysteine hydrochloride 20 mg) on the state of the carbohydrate-protein components of the extracellular matrix in connective tissue of the liver in patients with non-alcoholic steatohepatitis (NASH) with obesity I-II degree and chronic kidney disease (CKD) І-ІІ stage. 98 patients with NASH on the background of obesity of the I-II degree were examined, including: 52 patients with NASH (I group) (without accompanying CKD), 46 patients with NASH with comorbid CKD І-ІІ stage (II group). The control group consisted of 20 practically healthy persons (PHPs) of the corresponding age and sex. Biopsy of the liver was performed on 32 NASH patients with CKD I-II, 28 patients with NASH without CKD. Patients on both groups of NASH received heparisin treatment (glycyrizine 40 mg, glycine 400 mg, L-cysteine hydrochloride 20 mg) (Valartin Pharma) by intravenous administration of 20 ml of the drug for 10 days followed by enteral administration of 2 tablets of heparysin (1 tablet : glycyrizine 25 mg, glycine - 25 mg, methionine - 25 mg) 3 times a day for 80 days. Patients with NASH and a comorbid flow of obesity and CKD of the І-ІІ stages, except for heparisin, received baseline therapy of CKD І-ІІ stage: chronic pyelonephritis. Heparizin therapy for 3 months contributed to the achievement of a collagen anabolic and catabolic balance by activating collagenase, inhibiting the activity of proteolytic inhibitors and collagenase, inhibition of fibroblast growth factor secretion, acute phase inflammation, reducing extracellular matrix fucoglycoproteinsdegradation in liver, and in general, reducing the activation of connective tissue components, by evidence which led to a decrease in the liver fibrosisindex according to the fibrotest in the range of 1.5-2.0 times.

Abstract
Glycyrrhhizic acid (GA), including 18α-glycyrrhizic acid (18α-GA) and 18β-glycyrrhizic acid (18β-GA), is the main active ingredient of licorice. GA is generally considered an effective pharmacological strategy protecting against hepatic disease; however, the optimal compatibility proportion of 18α-GA and 18β-GA against alcoholic liver disease (ALD) and the underlying mechanism are not well established. Hence, this study was designed to explore the optimal compatibility proportion of 18α-GA and 18β-GA against ALD, followed by investigating the underlying mechanisms. SD rats were administered 40% ethanol once a day, accompanied by treatment with different proportions of 18α-GA and 18β-GA for four weeks. Then all rats were anesthetized with chloral hydrate and blood samples were taken from the abdominal aorta for biochemical assay. Livers were also collected and the liver function, lipid profile, ROS production, and mRNA and protein levels of related genes involved in lipid metabolism were assessed. The results showed that 18α-GA and 18β-GA, particularly at a proportion of 4:6, significantly reduced liver damage, lipid accumulation, and oxidative stress in ethanol-induced rats, as indicated by the decreased levels of alanine aminotransferase (ALT) and aminotransferase (AST) in serum, improvement of liver histopathological changes, regulation of total cholesterol (TC), total triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), and modulation of superoxide dismutase (SOD), glutathione (GSH), and malonaldehyde (MDA). Moreover, the combination treatment with 18α-GA and 18β-GA substantially reduced the mRNA and protein levels of sterol regulatory element-binding protein-1c (SREBP-1c) and acetyl-coal carboxylase (ACC); meanwhile, increased levels of peroxisome proliferators activated receptor-α (PPAR-α) and carnitine palmitoy transferase-1 (CTP-1) in the liver tissues of ethanol-induced rats. In conclusion, our results indicated that the optimal compatibility proportion of 18α-GA and 18β-GA protecting against ALD was 4:6, and the mechanism was associated with the regulation of oxidative stress and lipid metabolism.

Abstract
PURPOSE Glycyrrhizin (GLY), an inhibitor of high-mobility group box 1 (HMGB1) protects prophylactically against Pseudomonas aeruginosa keratitis. However, the therapeutic potential of GLY to enhance an antibiotic has not been tested and is our purpose. METHODS C57BL/6 mice (B6) were infected with a clinical isolate (KEI 1025) of P. aeruginosa and treated topically at 6 h postinfection (p.i.) with GLY or phosphate-buffered saline (PBS). Clinical scores, photography with a slit lamp, enzyme-linked immunosorbent assay, myeloperoxidase assay, bacterial plate counts, histopathology, reactive oxygen/nitrogen species (ROS/RNS) assays, and in vitro macrophage (Mφ) stimulation assays were used to assess effects of GLY treatment. In separate similar experiments, the ability of GLY to bioenhance the antibiotic, tobramycin (TOB), was assessed. RESULTS In vivo, GLY versus PBS topical treatment began at 6 h p.i., improved disease outcome by significantly reducing clinical scores, proinflammatory proteins (HMGB1, RAGE, TLR4, TNF-α, and CXCL2), neutrophil infiltrate, bacterial load, ROS/RNS, and nitric oxide. In vitro, GLY downregulated iNOS and COX-2 expression (mRNA) in both mouse and human (THP-1) Mφ. At 6 and 24 h p.i., treatment with GLY enhanced the effects of TOB compared with TOB alone by significantly reducing corneal bacterial load and/or protein levels of cytokines CXCL2 and IL-1β. CONCLUSIONS Data provide evidence that GLY is not only therapeutic for Pseudomonas keratitis through its ability to reduce HMGB1, bacterial load, and oxidative damage but also through its bioenhancement of an antibiotic, even when treatment is initiated at 24 h after infection.

Abstract
RATIONALE Glycyrrhizin is the main active component of licorice. Licorice and glycyrrhizin induced hypertension has been widely reported, yet licorice and glycyrrhizin induced hypertensive crisis has been rarely known. PATIENT CONCERNS The case of this report was a 47-year-old woman, who took 225 mg of glycyrrhizin daily for 3 years due to primary biliary cholangitis. She was found to have a dramatically elevated blood pressure of about 230/110 mmHg without a history of hypertension and was referred to the emergency department. DIAGNOSES Hypokalemia, hypertensive retinopathy, and nephropathy were found during the following work-up. Since no other risk factors of hypertension were identified, she was suspected to have glycyrrhizin induced pseudo-hyperaldosteronism. INTERVENTIONS Glycyrrhizin was discontinued. Intravenous sodium nitroprusside was used during the first few days. Nifedipine and irbesartan were taken after discharge, and the dosage was reduced gradually under supervision. OUTCOMES She stopped all the anti-hypertensive drugs 6 months since glycyrrhizin was stopped. Her blood pressure was about 110/60 mmHg after repetitive measurement. Her serum potassium and urine albumin/creatinine ratio were also normalized. LESSONS Licorice and glycyrrhizin induced hypertension due to pseudo-hyperaldosteronism has been widely reported, yet only 3 cases reported that excessive consumption of licorice could lead to hypertensive emergencies. This is the first case that glycyrrhizin induced hypertensive crisis with target organ impairment. By presenting this case, we remind clinicians of glycyrrhizin induced hypertension, a condition which could lead to medical emergencies.

Abstract
Most traditional Chinese medicine prescription dosages are imprecise. This study analyzes the toxicities and adverse effects of a combination the active ingredients of licorice and Kushen medicine: oxymatrine (OMT) and diammonium glycyrrhizinate (DG). The median lethal dose (LD50) and mortality were analyzed in single-dose OMT (or DG) intraperitoneally injected mice with or without combination DG (or OMT). Body weight changes as well as levels of serum sodium and potassium, alanine transaminase (ALT), aspartate transaminase (AST), creatinine, and urea were measured in mice treated with a daily dose of OMT and/or DG for 14days. This study showed that the LD50 of OMT for males and females were 347.44 and 429.15mg/kg, respectively. The LD50 of DG were 525.10 and 997.26mg/kg for males and females, respectively. DG significantly decreased the mice LD50-induced mortality of the OMT, however OMT did not succeed in reducing the LD50-induced mortality rate of DG. The combination of OMT and DG obviously attenuated the changes of the body weight, serum sodium, and potassium induced by DG or OMT alone. These results suggested that toxicity and adverse effects of the OMT was significantly attenuated by DG. The OMT neutralized the adverse effects of the DG, but not the toxicity.

Abstract
An attempt was made to characterize the pharmacokinetic profiles of Qishen Keli (QSKL) that has been widely proved to be effective in clinical practice. A method using ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) for the simultaneous determination of 25 analytes in rat plasma was developed and validated. Satisfactory chromatographic separation was achieved on an ACQUITY UPLC HSS T3 column with gradient elution using mobile phase consisting of 0.02% aqueous formic acid (A) and acetonitrile fortified with 0.02% formic acid (B), and analyte detection was carried out using polarity-switching multiple reaction monitoring mode. Method validation assays in terms of selectivity, linearity, inter- and intra-day variations, matrix effect, and recovery demonstrated the newly developed method to be specific, sensitive, accurate, and precise. Following the oral administration of QSKL at a single dose, the qualified method was successfully applied for pharmacokinetic investigations in sham and model rats. Mild differences occurred for the pharmacokinetic patterns of most components between those two groups, whereas significant differences were observed for glycyrrhizic acid and glycyrrhetic acid. The obtained findings could provide meaningful information for the clarification of the effective material basis of QSKL.

Abstract
BACKGROUND Hyaluronic acid (HA), the major glycosaminoglycan present in the human skin, is a key contributor to water retention and mechanical support in skin. The level, size, and functionality of cutaneous HA are known to diminish with age. Topical treatments designed to increase the HA content of skin have been met with limited success. The purpose of this study was to evaluate the tolerance and efficacy of a multi-modal facial serum containing HA, Proxylane (C-Xyloside), purple rice extract, and dipotassium glycyrrhizate in addressing HA levels in skin. METHODS A 12-week, single center, clinical study was conducted on 59 women with mild to moderate photodamage. Clinical grading to assess the efficacy and tolerability was conducted on the face at baseline and at weeks 4, 8, and 12. Bioinstrumentation measurements were taken, including corneometer, tewameter, ultrasound, and standardized digital imaging. A randomized subset of 20 subjects from the study population had 3 mm punch biopsies collected for quantitative RT-PCR analysis from 2 sites on the face at baseline and week 12. Additionally, a 4-week, single center, clinical study was conducted on the photodamaged forearms of 12 subjects. At both baseline and week 4, a 4 mm punch biopsy was obtained from the subjects' randomized forearms. Biopsy samples were subjected to immunohistochemical staining and analysis of HA content. RESULTS Statistically-significant improvements in all facial skin attributes (weeks 4, 8, and 12), stratum corneum hydration (week 12), and transepidermal water loss (week 12) were observed. Tolerability was excellent, with no increases in irritation parameters noted. A significant increase of HA content in skin after 4 weeks of treatment was observed. By PCR analysis, there was a significant increase in hyaluronan synthase 2, as well as a significant increase in collagen type 1a1 after 12 weeks of application. CONCLUSION The findings suggest that this novel topical facial serum is capable of stimulating HA and skin extracellular matrix components, as well as improving skin hydration and skin quality in women with mild to moderate photodamage. <p><em>J Drugs Dermatol. 2017;16(9):884-890.</em></p>.

Abstract
Objective To investigate the immunological effect of glycyrrhizic acid (GA) on MRL/lpr mice and its underlying mechanism. Methods The research included 10 wild type C57BL/6 mice and 40 MRL/lpr mice. MRL/lpr mice were randomly assigned to four groups: MRL/lpr control, MRL/lpr treated with dexamethasone (1.5 mg/kg), MRL/lpr treated with GA (20 mg/kg) and GA (40 mg/kg), 10 mice in each group. The serum levels of interleukin 4 (IL-4) and interferon-γ (IFN-γ) were tested by ELISA. The ratio of Th1/Th2 cell subsets in spleen was analyzed by flow cytometry. The protein levels of GATA-binding protein 3 (GATA3), T-bet, p-JAK3, JAK3, phosphorylated signal transducer and activator of transcription 3 (p-STAT3), STAT3, p-NF-κBp65, NF-κBp65, p-IκBα, IκBα in spleen were detected by Western blot analysis. Results GA decreased serum levels of IL-4 and increased IFN-γ, modulated the balance of Th1/Th2 cell subsets in spleen markedly. GA inhibited the protein levels of GATA3, p-JAK3, p-STAT3, p-NF-κB, p-IκBα and increased T-bet protein in MRL/lpr mice. Conclusion Administration of GA can ameliorate the immune function in MRL/lpr mice.

Abstract
The absorption modulating activity of two alkylglycerol derivatives (batyl and chimyl alcohol) on skin barrier properties was evaluated. Biophysical tests such as transepidermal water loss (TEWL) and attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy, as well as in vitro skin permeation studies, were performed in order to determine the effect of these compounds as chemical absorption modulators. Four drugs were used as models: three NSAIDS (diclofenac, naproxen, and piroxicam) and glycyrrhizic acid. The results showed that treatment of the skin with alkylglycerols caused (i) a reduction on the amount of drug permeated; (ii) a reduction in TEWL; and (iii) changes in the ATR-FTIR peaks of stratum corneum lipids, indicative of a more ordered structure. All of these findings confirm that alkyl glycerols have an absorption retarding effect on the drugs tested. Such effects are expected to give rise to important applications in the pharmaceutical and cosmetic sectors, in cases where it is desirable for the drug to remain in the superficial layers of the skin to achieve a local effect.

Abstract
Addison's disease is a relatively common disorder to endocrinologists, but is rare and potentially fatal when presenting acutely. Treatment now involves replacement of glucocorticoids and mineralocorticoids with synthetic compounds, although historically patients took common salt and plant-based preparations. We describe the case of a 42-year-old woman who self-treated undiagnosed Addison's disease for several years with soy sauce and liquorice sticks. She presented with a four-week history of decreased energy, malaise and postural dizziness. Our patient described an unusual diet of liquorice sticks and soy sauce, consuming around 46 g of salt per week. There was a family history of Type 1 diabetes mellitus. Physical examination was unremarkable, although subsequent investigation confirmed Addison's disease. Liquorice provided glycyrrhizic acid and glycyrrhetinic acid, which act on 11-beta hydroxysteroid dehydrogenase enzymes. In this case, the net effect was potentiation of glucocorticoid action on renal mineralocorticoid receptors in the context of failing adrenocortical steroid production. The case highlights the importance of taking a dietary history to aid diagnosis.

Abstract
CONTEXT Drug-induced liver injury (DILI) is associated with altering expression of hepatobiliary membrane transporters. Monoammonium glycyrrhizin (MAG) is commonly used for hepatic protection and may have a correlation with the inhibition effect of multidrug resistance-associated protein 2 (Mrp2). OBJECTIVE This study evaluates the dynamic protective effect of MAG on rifampicin (RIF)- and isoniazid (INH)-induced hepatotoxicity in rats. MATERIALS AND METHODS Male Wistar rats were randomly divided into four groups of 15 rats. Liver injury was induced by co-treatment with RIF (60 mg/kg) and INH (60 mg/kg) by gavage administration; MAG was orally pretreated at the doses of 45 or 90 mg/kg 3 h before RIF and INH. Rats in each group were sacrificed at 7, 14, and 21 d time points after drug administration. RESULTS Liver function, histopathological analysis, and oxidative stress factors were significantly altered in each group. The expression of Mrp2 was significantly increased 230, 760, and 990% at 7, 14, and 21 time points, respectively, in RIF- and INH-treated rats. Compared with the RIF and INH groups, Mrp2 was reduced and Ntcp was significantly elevated by 180, 140, and 160% in the MAG high-dose group at the three time points, respectively. The immunoreaction intensity of Oatp1a4 was increased 170, 190, and 370% in the MAG low-dose group and 160, 290, and 420% in the MAG high-dose group at the three time points, respectively, compared with the RIF and INH groups. DISCUSSION AND CONCLUSION These results indicated that MAG has a protective effects against RIF- and INH-induced hepatotoxicity. The underlying mechanism may have correlation with its effect on regulating the expression of hepatobiliary membrane transporters.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Glycyrrhiza uralensis Fisch. and processed radix Aconiti kusnezoffii are the main components in many Chinese traditional patent medicines with the ratio of 1:1, which are used for treatment of rheumatoid arthritis, heart failure and so on. Glycyrrhizic acid, glycyrrhetic acid, liquiritigenin and isoliquiritigenin are the essential bioactive triterpenes and flavones in the extract of G. uralensis, which were analysis by a simple but accurate method. MATERIALS AND METHODS In the present study, a specific HPLC method was developed and validated for simultaneous determination of pharmacokinetic parameters of glycyrrhizic acid, glycyrrhetic acid, liquiritigenin and isoliquiritigenin in G. uralensis after oral administration of single herb extract and a combination of two herbs extracts respectively. RESULTS The calibration curves of the four components had good linearity higher than 0.9991 in the measured range. The intra-day and inter-day precisions (RSD) at different levels were both within 9.73%, and the accuracies (RE) were in the range of -7.9-8.0%. Compared with pharmacokinetic parameters of G. uralensis administered orally, values of AUC and Cmax of liquiritigenin and isoliquiritigenin decreased significantly (p<0.05), plasma concentrations of glycyrrhizic acid rose slightly and bimodal phenomenon of concentration-time of isoliquiritigenin and glycyrrhetinic acid disappeared after combined administration. DISCUSSION AND CONCLUSIONS Some components in the extract of processed radix A. kusnezoffii showed different effects on the pharmacokinetics of the four ingredients in G. uralensis.

Abstract
AIM Despite the availability of a number of pharmacological options, relief of allergic rhinitis (AR) symptoms, especially nasal obstruction, is often limited and local and systemic adverse reactions are not infrequent. The main aim of the present pilot study was to provide subjective and objective evidence of the clinical efficacy in reducing symptoms and safety of a medical device-Grip stop DMG (lactoferrin, carboximetil β-glucan, D-panthenol, dipotassiumglycyrrhizinate) in children affected by allergic rhinitis. METHODS A prospective study with a pre- and post-design has been performed consecutively enrolling 50 pediatric both genders patients affected by persistent AR. Patients received 2 puffs into each nostril twice a day over the course of 4 weeks. The severity of AR symptoms was assessed subjectively as measured by a 0 to 5 Visual Analog Scale, and objectively through active anterior rhinomanometry (AAR) and by means of the evaluation of mucociliary transport time (MCTt). Differences in symptoms scores measured before and after the treatment were compared using Paired-Sample Wilcoxon Signed Rank Test. Proportion of participants with adverse effects attributed to the treatment was computed. The relationship between the subjective score and the AAR and MCT measurements was also assessed. RESULTS All considered symptoms, including nasal congestion, significantly improved after treatment (P<0.001), while only 1 patient suffered from moderate adverse effects. CONCLUSION Results confirm efficacy and safety of this device used in the pediatric population. As previously reported in the scientific literature, also in our study, patient's perception of nasal symptoms corresponded with objective testing.

Abstract
Paclitaxel (PTX, taxol), a classical antitumor drug against a wide range of tumors, shows poor oral bioavailability. In order to improve the oral bioavailability of PTX, glycyrrhizic acid (GA) was used as the carrier in this study. This was the first report on the preparation, characterization and the pharmacokinetic study in rats of PTX-loaded GA micelles The PTX-loaded micelles, prepared with ultrasonic dispersion method, displayed small particle sizes and spherical shapes. Differential scanning calorimeter (DSC) thermograms indicated that PTX was entrapped in the GA micelles and existed as an amorphous state. The encapsulation efficiency was about 90%, and the drug loading rate could reach up to 7.90%. PTX-loaded GA micelles displayed a delayed drug release compared to Taxol in the in vitro release experiment. In pharmacokinetic study via oral administration, the area under the plasma concentration-time curve (AUC0→24 h) of PTX-loaded GA micelles was about six times higher than that of Taxol (p < 0.05). The significant oral absorption enhancement of PTX from PTX-loaded GA micelles could be largely due to the increased absorption in jejunum and colon intestine. All these results suggested that GA would be a promising carrier for the oral delivery of PTX.

Abstract
OBJECTIVE To determine the impact of phlebotomy on the laboratory values and the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C. METHODS Study patients with chronic hepatitis C were treated with glycyrrhizin injection and oral ursodeoxycholic acid and either with (n=52) or without (n=50) phlebotomy during the period of 2005-2012. Six phlebotomized patients had previously received interferon therapy and were subsequently excluded from the data analysis. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, alkaline phosphatase, gamma-glutamyl transpeptidase, lactate dehydrogenase, ferritin, iron and albumin, as well as the hemoglobin concentration, platelet count and prothrombin time, were determined. We compared the long-term outcomes based on the incidence of HCC and laboratory values, including the baseline serum ferritin levels, in patients treated with versus without phlebotomy. RESULTS In the phlebotomy group, the mean AST and ALT levels decreased significantly at each one-year interval over five years (p<0.01), whereas the platelet counts did not. The incidence of HCC in the phlebotomized patients was significantly lower than that observed in the patients treated without phlebotomy: 10.3% vs. 43.7%, respectively, during the 8-year observation period (p=0.04). The incidence of HCC was also lower in the phlebotomized patients with a normal baseline ferritin level: 0.0% vs. 36.0% in the matched subgroup treated without phlebotomy at year 8. Phlebotomy offered a risk ratio of 0.13, thus suggesting protection against the development of HCC. CONCLUSION The incidence of HCC can be reduced by phlebotomy treatment, which should be performed in patients with chronic hepatitis C not receiving or not responding to antiviral therapy.

Abstract
The effect of liquorice root derivatives (LRDs) glycyrrhizic acid (GL) and glycyrrhetinic acid (18βGA) on salt and water balance and end points of gill ion transport in a freshwater teleost, (rainbow trout) was examined after feeding fish diets containing GL or 18βGA (0, 5, 50 or 500 µg/g diet) for a two week period. Serum cortisol levels and gill 11β-hydroxysteroid dehydrogenase type 2 mRNA abundance decreased in fish fed GL but increased (at select doses) in fish fed 18βGA. At higher doses of GL, gill Na(+)-K(+)-ATPase and H(+)-ATPase activity increased, while cystic fibrosis transmembrane conductance regulator type II mRNA abundance significantly decreased at the lowest dose of GL. End points of gill transcellular ion transport were not significantly altered in fish fed 18βGA, except for a reduction in Na(+)-K(+)-ATPase activity at a 50 µg/g dose. In contrast, high doses of GL and 18βGA increased gill transcript abundance of the tight junction protein claudin-31 (cldn-31). Other end points of gill paracellular transport differed in fishes fed LRDs. Tricellulin mRNA abundance was increased by high dose GL and decreased by high dose 18βGA, and cldn-23a and cldn-27b mRNA abundance significantly decreased in response to GL irrespective of dose. Despite the above observations, systemic end points of salt and water balance (i.e. serum [Na(+)] and [Cl(-)] as well as muscle moisture) were unaffected by LRDs. Therefore data suggest that LRDs can alter end points of ion transport in fishes but that overall salt and water balance need not be perturbed.

Abstract
CONTEXT Anecdotic reports from Turkmenistan suggest an epilatory effect of sweet licorice extract after topical application. OBJECTIVE This study examines hair removal after topical application of glycyrrhizic acid, the main compound of sweet licorice. MATERIALS AND METHODS An aqueous solution containing 15% of the ammonium salt of glycyrrhizic acid, 10% urea, and 20% ethanol was topically applied two times per day on the neck areas of Wistar rats using a toothbrush. RESULTS After 3 d, 20-30% of the treated areas were free of hair. After treatment for 6-12 d, 90-95% of the hair was gone. Clinical as well as immunohistological examinations showed no signs of inflammation even after long-term treatment for more than 9 months. Interestingly, long-term treatment reduced the regrowth of hair of about 20%. Examination by scanning electron microscopy showed a smoothed hair cuticle that might facilitate detachment of the hair shaft from the follicular wall. DISCUSSION AND CONCLUSION Our findings suggest glycyrrhizic acid as an interesting molecule for treating hypertrichosis in humans.

Abstract
BACKGROUND Liquorice extracts demonstrate therapeutic efficacy in treating dermatitis, eczema, and psoriasis when compared with corticosteroids. In this work, nonionic surfactant vesicles (niosomes, NSVs) containing polysorbate 20 (Tween 20), cholesterol, and cholesteryl hemisuccinate at different molar concentrations were used to prepare monoammonium glycyrrhizinate (AG)-loaded NSVs. The anti-inflammatory properties of AG-loaded NSVs were investigated in murine models. METHODS The physicochemical properties of the NSVs were characterized using dynamic light scattering. The fluidity of the lipid bilayer was evaluated by measuring the fluorescence intensity of diphenylhexatriene. The drug entrapment efficiency of AG was assessed using high-performance liquid chromatography. The physicochemical stability of the NSVs was evaluated as a function of time using dynamic light scattering combined with Turbiscan Lab Expert analysis. Serum stability was determined by incubating the NSVs with 10% v/v fetal bovine serum. The cytotoxic effects of the NSVs were investigated in human dermal fibroblasts using the Trypan blue dye exclusion assay (for cell mortality) and an MTT assay (for cell viability). Release profiles for the AG-loaded NSVs were studied in vitro using cellulose membranes. NSVs showing the most desirable physicochemical properties were selected to test for in vivo anti-inflammatory activity in murine models. The anti-inflammatory activity of the NSVs was investigated by measuring edema and nociception in mice stimulated with chemical agents. RESULTS NSVs showed favorable physicochemical properties for in vitro and in vivo administration. In addition, they demonstrated long-term stability based on Turbiscan Lab Expert analysis. The membrane fluidity of the NSVs was not affected by self-assembling of the surfactants into colloidal structures. Fluorescence anisotropy was found to be independent of the molar ratios of cholesteryl hemisuccinate and/or cholesterol during preparation of the NSVs. The anti-inflammatory AG drug showed no effect on the stability of the NSVs. In vivo experiments demonstrated that AG-loaded NSVs decreased edema and nociceptive responses when compared with AG alone and empty NSVs. In vitro and in vivo results demonstrated that pH sensitive and neutral NSVs show no statistical significant difference. CONCLUSION NSVs were nontoxic and showed features favorable for potential administration in vivo. In addition, neutral NSVs showed signs of increased anti-inflammatory and antinociceptive responses when compared with AG.

Abstract
AIM This study assesses the efficacy of a new non steroid anti-inflammatory product in comparison to Hydrocortisone Butyrate 0.1% Cream in healing eczematous dermatitis. METHODS A bilateral controlled randomized pilot study was conducted in Italian adults affected by eczema with at least two symmetric lesions at baseline, respectively assigned to a non steroid cream or Hydrocortisone. The severity of lesions was judged through the Global Clinical Score (GCS) and the recovery was defined as a GSC equal to 0. The study investigated: 1) the differences in GCS between four points in time during therapy (baseline, four, eight, twelve weeks), according to medication received; 2) treatment efficacy. RESULTS The study showed that time, treatment and interaction between treatment and time were associated with GCS; moreover, lesions treated with Hydrocortisone went better on the whole but the post-hoc analysis showed a significant clinical improving at each point in time only for the non steroid cream. At the end of the study, in the intention to treat analysis, lesions recovered in 76.1% and 40.3% patients treated with Hydrocortisone and with the non steroid cream respectively; in the per protocol population, recovery was achieved in 91.7% and 58.3% of cases. CONCLUSION According to the results, the non steroid cream has been demonstrated effective in reducing the severity of eczema and may be used with continuing success in the long term treatment of the disease.

Abstract
This review summarizes new treatments from the last seven years employed for the treatment of genital warts caused by human papillomavirus (HPV). Imquimod 3.75% is a new agent with fewer side effects and perhaps a better dosing schedule than imquimod 5%, but is not more effective. Sinecatechins/Polyphenon E 15%, a novel extract from green tea can be effective against genital warts but requires three times a day dosing and is not more effective than existing treatments; the treatment course is 12-16 weeks. Photodynamic therapy combined with other destructive modalities might increase the cure rate for genital warts. The quadrivalent vaccine against HPV 6, 11, 16, 18 is decreasing the incidence of warts in the western world but the evidence does not support vaccination as a treatment for those already infected by HPV. Hyperthermia and immunomodulators might be positive additions to the armamentarium of clinicians. In sum, there are new tools that physicians can use but none is really a great advance over what was available a decade ago.

Abstract
BACKGROUND Cyclosporine A (CsA) has been widely used in the treatment of aplastic anemia (AA), but the application of CsA was limited in patients who had liver diseases or abnormal liver function due to its liver toxicity. Glycyrrhizin has long been used in China in the treatment of various liver diseases to lower transaminases. In this study, we observed the efficacy and safety of glycyrrhizic acid combined with CsA in the treatment of newly diagnosed patients with non-severe AA (NSAA). METHODS A total number of 76 patients with newly diagnosed NSAA were enrolled into the study at our hospital between July 2005 and June 2010. The patients were divided randomly into two groups: the glycyrrhizin-treatment group (group A) and the control group (group B) with 38 patients in each group. All patients received 3 - 5 mg×kg(-1)×d(-1) CsA for at least 4 months and were treated either with or without glycyrrhizin for 4 months. RESULTS sixty-eight patients were eligible for evaluation. In the control group, 9.09% patients (n = 3) achieved a complete response while 51.52% (n = 17) attained a partial response. The overall response rate was 60.61% (n = 20). The remaining 13 patients (39.39%) did not have any response. In the glycyrrhizin-treatment group, complete response rate was 20% (n = 7) and partial response rate was 62.86% (n = 22). The overall response rate was 82.86% (n = 29) and the non-response rate was 17.14% (n = 6). Response rate was significantly increased with the addition of glycyrrhizin to CsA compared with CsA alone (P < 0.05). CONCLUSION The combination of glycyrrhizin and cyclosporine regimen was an effective treatment for NSAA in terms of improvement of response rate, reduction in CsA-related liver injury, and attenuation of severity of nausea and other adverse events in the treatment of patients with NSAA.

Abstract
The purpose of the study was to evaluate the modulating effect of glutamyl-tryptophan (EW), glycyrrhizic acid (GA), and their combination on the course of experimental infection caused by influenza A (H3N2) virus in mice. The animals were infected with influenza A/Aichi/2/68 (H3N2) virus in a dose of 1 or 10 LD50. GA (10 mg/kg body weight) and EW (0.1, 10, and 1000 microg/kg) alone or in combination were intraperitoneally injected for 5 days, starting on day 1 of virus infection. Rimantadine 50 mg/kg/day was used as a comparison drug. The combination of EW (1000 microg/kg) and GA (10 mg/kg) was ascertained to exert the maximum protective effect manifesting itself in reducing the death of infected animals (by 75-79% compared to the control depending on the viral dose) and the titers of viruses accumulated in the lung (5-6 log EID50) and in preventing lung tissue edema and inflammation. The noted effect was comparable with that seen in the use of rimantadine. The agents used alone had a lower efficacy than rimantadine. The findings permit the combination of GA and EW to be considered to be a promising agent for the treatment of influenza.

Abstract
OBJECTIVE To explore effects of kurarinol combined with Diammonium Glycyrrhizinate on specific cellular immunity of patients with chronic hepatitis B (CHB). METHODS Sixty-three CHB patients were randomly divided into two groups, 32 cases in group of kurarinol combined with Diammonium Glycyrrhizinate group (combined therapy group) were treated with 600 mg kurarinol glucose injection intravenously, once a day for one month, then 200 mg kurarinol capsule was used orally, three times a day for two months. 150 mg Diammonium Glycyrrhizinate for Injection was added to 250 ml 10% glucose injection for intravenous drip, once a day for one month, then 150 mg Diammonium Glycyrrhizinate capsule was used orally, three times a day for two months; 31 case in kurarinol group (single drug group) only used kurarinol, methods and dosage were the same as those of treatment group. HBV specific CTL, T cell subgroups, change of Th1 and Th2 level, HBV-DNA and HBeAg negative rate of the two groups were compared. RESULTS Three months after treatment, HBV specific CTL, CD4 + and Th1 of combined therapy group were higher than those before treatment, and higher than those of single drug group after treatment (P < 0.01). CONCLUSION HBV-DNA and HBeAg negative rate between the two groups had no statistic significance (P > 0.05). CONCLUSION Kurarinol combined with Diammonium Glycyrrhizinate can further increase HBV specific CTL, CD4+ and Th1 level of CHB patients.

Abstract
OBJECTIVE To optimize a compound prescription for treatment of liver fibrosis with an improved therapeutic effect and low toxicity. METHODS In rat models of liver fibrosis induced by thioacetamide (TAA), the optimized prescription was screened based on a uniform design with 2-factor 5-level table using Uniform Design 3.0 software and tested using liver content of Hyp as the screening index. To verify the efficacy of the optimized prescription, the rat models of liver fibrosis were randomized into normal control group, model group, colchicine group and optimized prescription group, and the changes of hepatic Hyp content, serum HA, ALT, AST, and ALB levels, and the pathology liver fibrosis were observed after corresponding treatments. RESULTS The optimized prescription, which contained 70 mg/kg glycyrrhizin and 70 mg/kg matrine, showed a significant therapeutic effect against liver fibrosis in rats (Plt;0.05), and the effect was equivalent to that of colchicine (P>0.05). CONCLUSION Uniform design is a valuable method in prescription optimization. The optimized compound prescription of matrine and glycyrrhizin has a significant effect in inhibiting liver fibrosis.

Abstract
BACKGROUND Acute onset autoimmune hepatitis (AIH) shows acute presentation like acute hepatitis and does not have typical clinicopathological features of AIH. There is no gold standard for making the diagnosis. Therefore, losing the timing of starting immunosuppressive therapy, some of the cases develop into severe or fulminant form and have poor prognosis. AIMS Our aim was to elucidate the efficacy of intravenous glycyrrhizin in decreasing alanine aminotransferase (ALT) level in the early stage of acute onset AIH. METHODS Thirty-one patients were defined as acute onset AIH based on our uniform criteria, and were enrolled in this study. We prospectively treated 17 patients with sufficient doses (100 ml/day) of intravenous glycyrrhizin (SNMC) at an early stage (SNMC group), and treated 14 patients of severe disease with intravenous glycyrrhizin and corticosteroids (CS) (SNMC + CS group). We examined their clinical and biochemical features and treatment responses. RESULTS The ALT level could be controlled at an early stage using SNMC with no significant difference compared with SNMC + CS, and responsiveness to the therapy was determined by the disease severity at the time of starting therapy rather than the time duration from onset to therapy. Recovery rate was higher in the SNMC group than in the SNMC + CS group (P = 0.035). CONCLUSIONS The early introduction of sufficient doses of SNMC might prevent disease progression in patients with acute onset AIH. SNMC can be used safely and be useful for patients with difficult-to-diagnose acute liver disease as an 'initial' treatment tool to improve liver inflammation before starting disease-specific treatments.

Abstract
Shaoyao-Gancao-Tang (SGT), a traditional Chinese formulation composed of Shaoyao (Paeoniae Radix) and Gancao (Glycyrrhizae Radix), is frequently used in conjunction with laxatives such as sodium picosulfate in colonoscopy to relieve abdominal pains. We have investigated the alterations of the bioavailability of glycyrrhizin when SGT was co-administered with sodium picosulfate and we tried to identify a regimen that might minimize the alterations. Glycyrrhizin is one of the active glycosides in Gancao and SGT and is hydrolysed into the bioactive metabolite, 18β-glycyrrhetic acid (GA) by intestinal bacteria following oral administration. We found that the maximum plasma concentration (Cmax) and the area under the mean concentration vs time curve from zero to 24 h (AUC0–24 h) of GA from a single dose of SGT administered 5 h after a single pretreatment with sodium picosulfate were significantly reduced to 15% and 20% of the control level in rats, respectively. These reductions were still significant four days after sodium picosulfate pretreatment, but were restored by repetitive administration of SGT following sodium picosulfate pretreatment. Similar reductions and recovery were observed for the glycyrrhizin-metabolizing activity of intestinal bacteria in rat faeces. The results warrant clinical studies for co-administration of laxatives such as sodium picosulfate and SGT.

Abstract
OBJECTIVE The aim of this study is to develop a simple and rapid HPLC method and investigate the effect of glycyrrhizin on pharmacokinetic fate of paeoniflorin after intravenous administration. METHOD Paeoniflorin and glycyrrhizin was administrated to rat via vena caudalis, and paeoniflorin in rat plasm was determined by RP HPLC method and internal standard method. All data were subsequently processed by the pharmacokinetic Software WinNonLin. The non-compartmental pharmacokinetic parameters of area under the plasma concentration-time curve (AUC/min x mg x L(-1)), clearance (CL/mL x min(-1) x kg(-1) ) and volume of distribution (Vd/mL x kg(-1)) were calculated based on moment methods. RESULT The values of AUC, V(d) and CL was 166.81 +/- 26.94, 394.33 +/- 29.52, 18.40 +/- 3.12 in control group, respectively; however, the values of AUC, V(d), CL was 235.44 +/- 46.48, 266.63 +/- 48.43 and 13.16 +/- 2.59 in experimental group. CONCLUSION Glycyrrhizin significantly influenced the pharmacokinetic fate of paeoniflorin, increasing the value of AUC and decreasing CL and V(d).

Abstract
Glycyrrhizin (GZ) and licorice (root of Glycyrrhiza uralensis) are worldwide food additives and important oriental phytomedicines. This study investigated the biological fate of GZ by orally giving GZ and licorice decoction (LD) to rats. The serum concentrations of GZ and glycyrrhetic acid (GA) were determined by high performance liquid chromatography. The results showed that GZ was not detected and GA was present in serum until 3 days postdosing of GZ and LD. To evaluate the effects of GZ and licorice on the pharmacokinetics of methotrexate (MTX), an important immunosuppressant with a narrow therapeutic window, rats were orally given MTX with and without GZ and LD in different dosage regimens. The serum MTX concentration was determined by fluorescence polarization immunoassay. The results revealed that the AUC and MRT of MTX were significantly increased by GZ and LD. In conclusion, the concurrent use of GZ or licorice with MTX should be with caution.

Abstract
OBJECTIVE To investigate the effects of glycyrrhizin (GL) on the expression of hepatitis B virus e antigen (HBeAg), HBV DNA, Toll-like receptors 2,4 (TLR2,4) and proliferation of cells in HepG2.2.15 cell line. METHODS Real-time PCR examined HBV DNA, ELISA examined HBsAg, HBeAg and MTT examined the proliferation of cells. FCM examined the positive percent of cells expressing TLR2,4 before and after stimulated with GL, in contrast to the blank group. RESULTS The expression of HBsAg was low in the cell line, so e antigen was studied. The total HBeAg mean was significantly difference on the second day after stimulated (P<0.01), but only in the group with 400 microg/ml HBeAg decreased significantly in contrast to the blank group (P<0.05), the group with 800 microg/ml increased significantly in contrast to the other groups (P<0.01). The total HBV DNA mean on the third day after stimulated was significant, only the group with 50 microg/ml decreased in contrast to the blank group, but P>0.05, the other four groups increased. The intensity of TLR4 expression in the cells was significantly higher than that of the control group (P<0.05), both of total mean TLR2,4 increased significantly (P<0.01). The four groups except the group with 200 microg/ml increased significantly in no dose-dependent manner (P<0.05). GL in three goups under 200 microg/ml all could make cells proliferate, but only 200 microg/ml group had significant difference compared to the blank group (P<0.05). Both 400 and 800 microg/ml groups inhibited the growth of cells (P<0.01). The proliferation of cells were notably negative correlated with the expression of HBeAg, HBV DNA (P<0.05). CONCLUSION The study suggestes GL could inhibit or promote HBV DNA replicating and e antigen secreting in mutative HepG2.2.15 cell line, the correlation between the proliferation of cells and the both are negative. GL could upregulate TLR2,4 in no dose-dependent manner. Influencing HBV maybe have no correlation to up regulating TLR2,4 by GL at least in vitro.

Abstract
In Japan, glycyrrhizin injections have been used as a therapeutic drug for allergy inflammation since 1948 and for chronic hepatitis since 1979. A 20 ml injection of glycyrrhizin contains 53 mg of monoammonium glycyrrhizinate (40 mg as glycyrrhizin acid), 400 mg of glycine, and 20 mg of L-cysteine. Patients receiving glycyrrhizin injections two or three times per week are forced to accept a decline in quality of life. Because administering glycyrrhizin by injection has some disadvantages, many researchers have systematically searched for novel glycyrrhizin formulations that can be administered through oral, rectal, intranasal, and subcutaneous routes. There are two problems, however, in developing new formulations: (1) glycyrrhizin has low membrane permeability and is thus poorly absorbed, and (2) highly concentrated glycyrrhizin readily forms gels in aqueous solutions. Here, we describe the utility of glycyrrhizin formulations prepared in safe solubility agents and absorption-enhancing agents, as assessed in animal experiments. We also discuss pharmaceutical issues in developing various glycyrrhizin formulations. In the near future, convenient pharmaceutical preparations of glycyrrhizin will be developed for chronic hepatitis patients who require glycyrrhizin therapy.

Abstract
We performed a small phlebotomy (50 ml) intermittently just before intravenous injection of glycyrrhizin (GL) in eight patients with chronic hepatitis C and continued this therapy until their serum ferritin levels dropped below 20 ng/ml without any changes of GL dosage. No patients had complications but one patient holded treatment according to their wishing. In seven patients who completed this therapy, the average amount of phlebotomized blood was 1221 +/- 1055 ml, their serum ferritin value significantly fell from 253 +/- 233 ng/ml to 18+/-5 ng/ml (p=0.038). Serum ALT levels also significantly decreased from 74 +/- 22 IU/L to 41 +/- 12 IU/L (p=0.001). Small intermittent phlebotomies before GL injection may be a effective treatment for hepatitis C.

Abstract
Glycyrrhiza glabra root is one of the common traditional Chinese medicines and used as flavoring and sweetening agents for tobaccos, chewing gums, candies, toothpaste and beverages. While glycyrrhizin is one of the main components in the extract of G. glabra root and has been characterized, the other components have not been well characterized. The mechanism of growth activation of breast cancer MCF-7 cells, including the activation of Erk1/2 and Akt, and the transcriptional regulation of estrogen-responsive genes, was examined by means of sulforhodamine B, luciferase reporter gene, real-time RT-PCR and Western blotting assays after the induction of the cells with the extract of G. glabra root. The extract has similar activity to that induced by 17beta-estradiol (E(2)), although glycyrrhizin did not show such an activity. Moreover, the estrogen receptor alpha-dependent neurite outgrowth induced by the extract was similar to that by E(2), whereas glycyrrhizin had no effect. Furthermore, the expression profile examined by cDNA microarray assay using a set of 120 estrogen-responsive genes, which were related to proliferation, transcription, transport, enzymes and signaling, showed a statistically significant correlation (R=0.47, P<0.0001) between the profiles for E(2) and the extract. However, the expression profile for glycyrrhizin was different from that of the extract and E(2). The results indicate that rapid signaling pathways, including Erk1/2 and Akt, and the subsequent transcriptional regulation are involved in the proliferation of MCF-7 cells induced by the extract of G. glabra root. Furthermore, the extract had estrogenic activity and a distinguishable profile of gene expression, suggesting the presence of potentially useful components other than glycyrrhizin in G. glabra root for hormone and anti-cancer therapies.

Abstract
The distribution characteristics of two glycyrrhizic acid (GL) epimers, i.e. alpha-GL and beta-GL in rat tissues were examined. At 5, 15, 30, 60, and 180 min after i.v. administration of a single alpha-GL or beta-GL injection (21.0 mg/kg) in rats, the concentrations of these epimers in rat tissues were determined by reverse phase-high performance liquid chromatography (RP-HPLC) using the internal standard method. Alpha-GL and beta-GL were both rapidly distributed in the tissues. The concentrations of alpha-GL in the liver were significantly higher than those of beta-GL, but were lower than or similar to those of beta-GL in the other tissues. The concentrations of alpha-GL in all the tissues declined rapidly, and were lower than or similar to the detection limit for quantification at 180 min after i.v. administration. However, beta-GL concentrations remained rather high in the tissues, and maintained 10-50% of their peak value. According to these results, distinct differences were found in the distribution and metabolism in the rat tissues after i.v. administration of the two GL epimers, with these differences being closely related to the different configuration of alpha-GL and beta-GL.

Abstract
For investigating the effects of a combination therapy of triptolide (TP) with glycyrrhizin (GL) in rats with collagen-induced arthritis (CIA), the arthritic index was examined, and the levels of anti-CII IgG, TNF-alpha and IL-10 in serum were measured by ELISA. Our results showed that combined triptolide and glycyrrhizin treatment (TP 13.40 microg, GL 26.78 mg) can reduce the arthritic index of CIA rats and decrease the level of anti-CII IgG and TNF-alpha in serum. The observed effect was similar to the one measured upon application of TP 17.86 microg, GL 26.78 mg and TP 17.86 microg. The level of IL-10 was not significantly different among the rats of the TP 17.86 microg, of the TP 17.86 microg, GL 26.78 mg and of the TP 13.40 microg, GL 26.78 mg groups while the IL-10 levels in rats of the TP 13.40 microg and GL 26.78 mg groups were significantly higher. Combined triptolide 13.40 microg and glycyrrhizin 26.78 mg can therefore significantly inhibit collagen induced arthritis, and the effect was similar to the one of triptolide at 17.86 microg.
