Abstract
The traditional Chinese medicine (TCM) bupleurum-ginger-licorice formula presents significant anti-cancer effects, but its active ingredients and inhibitory mechanism remain unclear. In this work, the core effective ingredient quercetin and its signal transducer and activator of transcription 3 (Stat3) receptor both were identified by network pharmacology. Quercetin is a low-toxicity, non-carcinogenic flavonoid with antioxidant, anti-inflammatory and anticancer activities, which is widely distributed in edible plants. Stat3 can bind to specific DNA response elements and serves as a transcription factor to promote the translation of some invasion/migration-related target genes, considered as a potential anticancer target. Here, molecular docking and molecular dynamics (MD) simulation both were used to explore molecular recognition of quercetin with Stat3. The results show that quercetin impairs DNA transcription efficiency by hindering Stat3 dimerization, partially destroying DNA conformation. Specifically, when the ligand occupies the SH2 cavity of the enzyme, spatial rejection is not conductive to phosphokinase binding. It indirectly prevents the phosphorylation of Y705 and the formation of Stat3 dimer. When the inhibitor binds to the DT1005 position, it obviously shortens the distance between DNA and DBD, enhances their binding capacity, and thereby reduces the degree of freedom required for transcription. This work not only provides the binding modes between Stat3 and quercetin, but also contributes to the optimization and design of such anti-cancer inhibitors.

Abstract
Leukemia is an incurable disease; it exhibits strong resistance to chemotherapy and other therapies, and it represents the most common childhood cancer and mortality. The cytotoxic of amygdalin (AMG) against the cell line of human monocytic leukemia (THP-1) was recorded, before determining other pharmacological effects. The cells were exposed to AMG for 24 hr at 37°C at different concentrations, the cytotoxic effect was determined via the MTT assay. The cells and the supernatant were collected for analyzing the oxidant/antioxidant status, apoptotic markers, and anti-microbial activity. Results showed a marked anti-proliferative cytotoxic effect of AMG which is concentration and time-dependent, the lipid peroxidation content was significantly decreased while the total thiol was increased in the treated cell line, significant up-regulation of Caspase-3 (Cas-3) and Bcl-2-associated X protein (BAX) and down-regulation of B-cell lymphoma 2 (Bcl-2). Furthermore, The bacterial activity was detected via Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and Disc Diffusion assays, while the antifungal evaluation was done by the Minimum Fungicidal Concentration (MFC). Antimicrobial experiments revealed that AMG exerted potent, broad-spectrum antimicrobial effects toward a diversity of dangerously infecting pathogens. In conclusion; the prevailing research suggests that AMG is an effective anticarcinogenic and antimicrobial substance. The utilization of AMG subsequently in masks or wound dressings to prevent bacterial & fungal infections, including mucormycosis following COVID-19, as well as infections caused by penicillium and aspergillus, is a highly effective strategy in combating resistant microorganisms.

Abstract
The standardization, objectification, and essence research of traditional Chinese medicine (TCM) syndrome influence the modernization and international development of TCM syndrome. A total of 253 relevant publications collected from the Web of Science Core Collection database from 2006 to 2020 were analyzed by bibliometric and content methods. The co-occurrence analysis of countries, institutions, journals, authors, and keywords analysis were carried out by using Citespace software. The high-yield institutions and high-impact authors contributed to TCM syndrome publications were concentrated in China. Since 2012, driven by some groundbreaking publications, the number of TCM syndrome literatures has increased rapidly. According to the results of bibliometric and content analysis, research hotspots in TCM syndrome in the last 15 years can be summarized in six aspects: (a) objectification research of four TCM diagnostic methods, (b) omics technology for the essence research of TCM syndrome, (c) research on TCM syndrome evaluation scale, (d) metagenomic technology for the essence research of TCM syndrome, (e) data mining technology for TCM syndrome differentiation, and (f) systematic research on TCM syndromes of chronic hepatitis B. Emerging trends can be identified according to the most recent keywords bursts: (a) TCM syndrome diagnostic models with multiple indexes should be constructed to develop personalized medicine. (b) The connotation of TCM syndrome should be verified through "syndrome detecting from recipe used," and the screened potential markers of TCM syndrome need clinical verification. (c) The intervention and integration of multi-disciplines is expected to find a new breakthrough in the research of TCM syndrome.

Chemical composition and cardiotropic activity of Ziziphora clinopodioides subsp. bungeana (Juz.) Rech.f. JOURNAL OF ETHNOPHARMACOLOGY 2023:116660. [PMID: 37253397 DOI: 10.1016/j.jep.2023.116660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/13/2023] [Accepted: 05/17/2023] [Indexed: 06/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ziziphora clinopodioides subsp. bungeana (Juz.) Rech.f. is a subshrub that is widely distributed in China, Kazakhstan, Kyrgyzstan, Mongolia, Russia, Tajikistan, Turkmenistan, and Uzbekistan. The species is used in traditional medicine for the relief of symptoms connected to cardiovascular diseases like coronary heart disease or hypertension. AIM OF THE STUDY was to validate traditional use of Z. clinopodioides subsp. bungeana for the treatment of coronary hearth diseases using in vivo models and to find active compounds responsible for the activity. MATERIALS AND METHODS Multiple extracts were obtained from the aerial parts of Z. clinopodioides subsp. bungeana using maceration, liquid-liquid extraction, CO2 extraction and ultrasound-assisted extraction. Preliminary screening studies for the evaluation of the efficacy of Z. clinopodioides subsp. bungeana extracts on the model of hemic hypoxia were performed. The most effective samples were selected and included in the main study. Stage 2 of the study evaluated the cardiotropic activity of the selected extracts on a model of chronic heart failure. Preparations were administered to animals intragastrically once a day for 28 days. For the isolation of individual compounds plant material was extracted with 96% ethanol. The obtained crude extract was sequentially extracted with n-hexane and dichloromethane and separated by chromatography on a Diaion HP-20 column. The obtained fractions were further subjected to Sephadex LH-20 column chromatography and eluted isocratically with 96% ethanol (EtOH) to yield subfractions, which were further separated by preparative HPLC to obtain 13 individual compounds. RESULTS Extracts obtained from Ziziphora clinopodioides subsp. bungeana (Juz.) Rech.f. herb were subjected to pharmacological screening for the evaluation of their efficacy on hemic hypoxia. Based on the obtained results, out of the sixteen tested extracts two (AR and US 60%) were selected for further evaluation of their cardiotropic activity. Modeling of chronic heart failure was carried out in accordance with the following stages: 1) anesthesia with chloral hydrate at a dose of 450 mg/kg, intraperitoneally, 2) artificial ventilation of the lungs, 3) thoracotomy, 4) modeling of permanent ischemic or ischemic-reperfusion damage. Both extracts effected the indicators of contraction and output, comparable to the reference drug - Monopril. Based on the extraction methods used to obtain RAF and US60 and data from the literature, it can be assumed that they contain compounds with medium polarity, including polyphenols and terpenoids. At the next stage three previously undescribed monoterpenoid derivatives - Ziziphoric acid (1), Ziziphoroside D (2) and 6'-malonylziziphoroside A (3), along with two previously described megastigmane glucosides - blumenol C glucoside (4), blumenol C 9-O-(6'-O-malonyl-beta-D-glucopyranoside (5) and two previously described monoterpenoids 7a-hydroxymintlactone (6), 7-hydroxypiperitone (7) together with six polyphenols - pinocembrine-7-O-rutinoside (8), chrysine-7-O-rutinoside (9), acacetin-7-O-rutinoside (10), luteolin-7-O-rutinoside (11), rutin (12) and rosmarinic acid (13) were isolated from Z. clinopodioides subsp. bungeana extracts. CONCLUSION Our results support the traditional use of Z. clinopodioides subsp. bungeana for the treatment of coronary diseases. As a result of Z. clinopodioides subsp. bungeana extracts screening in vivo, two extracts were selected as potential cardiotropic agents. Phytochemical analysis of the plant material led to the isolation of five terpenoid derivatives, two megastigmane glycosides, five flavonoids and one cinnamic acid derivative, which could be responsible for the reported biological activity. Future experiments are required to understand the mechanisms of action for the isolated compounds.

A cross-sectional survey of self-medication with Traditional Chinese Medicine for treatment and prevention of COVID-19. Complement Ther Med 2022; 71:102898. [PMID: 36372316 PMCID: PMC9650265 DOI: 10.1016/j.ctim.2022.102898] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 10/31/2022] [Accepted: 11/07/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE To investigate user behavioural profiles and the prevalence of self-medication with traditional Chinese medicine (TCM) for COVID-19 among the general public in China. DESIGN Cross-sectional study. SETTING Self-administered online survey was carried out between January and June 2021 in China. RESULTS A total of 1132 complete responses were received from a nationwide sample. A considerable proportion viewed TCM to be more effective than Western medicine for treating COVID-19 (67.1 %) and stated that it is safer to use TCM (63.5 %) and easier to access TCM for treating COVID-19 (63.5 %). A total of 16.4 % (95 %CI 14.3-18.7) reported ever self-medicating with TCM to resolve COVID-19 symptoms and 12.2 % (95 % CI 10.3-14.2) ever using TCM to prevent SARS-CoV-2 infection. Lianhua Qingwen capsule/granule (53.2 %), Ganmao granule (50.5 %) and Banlangen granule (44.6 %) were most commonly used to resolve COVID-19 symptoms whereas Banlangen granule (60.1 %) was commonly used for the prevention of SARS-CoV-2 infection. Older age participants, from rural areas, with chronic diseases, higher socioeconomic status, and a positive attitude towards TCM were more likely to self-medicate using TCM to resolve COVID-19 symptoms. CONCLUSION Self-medication with TCM during the COVID-19 pandemic for symptom control or prevention is prevalent. The findings of the user behavioural profile and types of TMCs commonly used in this study provide beneficial information for the development of strategies to improve public health-seeking behaviour and the performance of the country's healthcare system in the era of the COVID-19 pandemic.

Latent tree analysis for the identification and differentiation of evidence-based Traditional Chinese Medicine diagnostic patterns: A primer for clinicians. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 106:154392. [PMID: 35994848 DOI: 10.1016/j.phymed.2022.154392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 06/22/2022] [Accepted: 08/10/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND A supplementary chapter on the diagnostic patterns of Traditional Medicine, including Traditional Chinese Medicine (TCM), was introduced into the latest edition of the International Classification of Diseases (ICD-11). However, evidence-based rules are yet to be developed for pattern differentiation in patients with specific conventional medicine diagnoses. Without such standardised rules, the level of diagnostic agreement amongst practitioners is unsatisfactory. This may reduce the reliability of practice and the generalisability of clinical research. PURPOSE Using cross-sectional study data from patients with functional dyspepsia, we reviewed and illustrated a quantitative approach that combines TCM expertise and computer algorithmic capacity, namely latent tree analysis (LTA), to establish score-based pattern differentiation rules. REVIEW OF METHODS LTA consists of six major steps: (i) the development of a TCM clinical feature questionnaire; (ii) statistical pattern discovery; (iii) statistical pattern interpretation; (iv) TCM diagnostic pattern identification; (v) TCM diagnostic pattern quantification; and (vi) TCM diagnostic pattern differentiation. Step (i) involves the development of a comprehensive questionnaire covering all essential TCM clinical features of the disease of interest via a systematic review. Step (ii) to (iv) required input from TCM experts, with the algorithmic capacity provided by Lantern, a dedicated software for TCM LTA. MOTIVATIONAL EXAMPLE TO ILLUSTRATE THE METHODS LTA is used to quantify the diagnostic importance of various clinical features in each TCM diagnostic pattern in terms of mutual information and cumulative information coverage. LTA is also capable of deriving score-based differentiation rules for each TCM diagnostic pattern, with each clinical feature being provided with a numerical score for its presence. Subsequently, a summative threshold is generated to allow pattern differentiation. If the total score of a patient exceeded the threshold, the patient was diagnosed with that particular TCM diagnostic pattern. CONCLUSIONS LTA is a quantitative approach to improving the inter-rater reliability of TCM diagnosis and addressing the current lack of objectivity in the ICD-11. Future research should focus on how diagnostic information should be coupled with effectiveness evidence derived from network meta-analysis. This will enable the development of an implementable diagnostics-to-treatment scheme for further evaluation. If successful, this scheme will transform TCM practice in an evidence-based manner, while preserving the validity of the model.

Abstract
OBJECTIVE To treat patients with psoriasis vulgaris using Traditional Chinese Medicine (TCM), one must stratify patients into subtypes (known as TCM syndromes or Zheng) and apply appropriate TCM treatments to different subtypes. However, no unified symptom-based classification scheme of subtypes (Zheng) exists for psoriasis vulgaris. The present paper aims to classify patients with psoriasis vulgaris into different subtypes via the analysis of clinical TCM symptom and sign data. METHODS A cross-sectional survey was carried out in Beijing from 2005-2008, collecting clinical TCM symptom and sign data from 2764 patients with psoriasis vulgaris. Roughly 108 symptoms and signs were initially analyzed using latent tree analysis, with a selection of the resulting latent variables then used as features to cluster patients into subtypes. RESULTS The initial latent tree analysis yielded a model with 43 latent variables. The second phase of the analysis divided patients into three subtype groups with clear TCM Zheng connotations: 'blood deficiency and wind dryness'; 'blood heat'; and 'blood stasis'. CONCLUSIONS Via two-phase analysis of clinic symptom and sign data, three different Zheng subtypes were identified for psoriasis vulgaris. Statistical characteristics of the three subtypes are presented. This constitutes an evidence-based solution to the syndromedifferentiation problem that exists with psoriasis vulgaris.

Abstract
Ischemic heart diseases are one of the major causes of death worldwide. Effective restoration of blood flow can significantly improve patients' quality of life and reduce mortality. However, reperfusion injury cannot be ignored. Flavonoids possess well-established antioxidant properties; They also have other benefits that may be relevant for ameliorating myocardial ischemia-reperfusion injury (MIRI). In this review, we focus on flavonoids with cardiovascular-protection function and emphasize their pharmacological effects. The main mechanisms of flavonoid pharmacological activities against MIRI involve the following aspects: a) antioxidant, b) anti-inflammatory, c) anti-platelet aggregation, d) anti-apoptosis, and e) myocardial-function regulation activities. We also summarized the effectiveness of flavonoids for MIRI.

Abstract
Herbal combinations of Rhei Radix et Rhizoma, Gardeniae Fructus, Cimicifugae Rhizoma, and Ginseng Radix have been used in traditional formulas to treat the symptoms of heat and dryness. This study investigated the therapeutic effects of a natural compound mixture (PSM) of these herbal combinations, containing emodin, genipin, chlorogenic acid, cimigenoside, and ginsenoside Rb1, for the treatment of psoriasis and its underlying molecular mechanisms. PSM was applied topically to the dorsal skin lesions of imiquimod- (IMQ-) induced C57BL/6 mice, and the expression of the proinflammatory mediators was investigated. The topical application of 1% PSM reduced psoriasis-like symptoms in IMQ-induced C57BL/6 mice significantly. PSM also attenuated the production of IFN-γ, IL-1β, and IL-6 in skin lesions. Histological analysis showed that PSM had antipsoriatic effects by reducing the lesional epidermal thickness. Either M5 (IL-1α, IL-17A, IL-22, oncostatin M, and TNF-α, 10 ng/ml each) or IL-22- (100 ng/ml) stimulated HaCaT cells were used to examine the efficacy and underlying mechanism of PSM. In M5-stimulated HaCaT cells, PSM inhibited the production of C-X-C motif chemokine ligand (CXCL) 10 and C-C motif chemokine ligand (CCL) 20 effectively. Moreover, compared to the use of a single compound, it had synergistic inhibitory effects in CXCL8 production. PSM suppressed the phosphorylation of ERK1/2, p38, and STAT3 signaling pathways in M5-stimulated HaCaT cells. Furthermore, PSM reduced the proliferation rate and K16 and K17 expressions in IL-22-stimulated HaCaT cells by inhibiting the Akt/mTOR signaling pathway. These results suggest that PSM may have a therapeutic potential in the treatment of psoriasis lesions.

Abstract
The efficacy of traditional Chinese medicine (TCM) treatments for Western medicine (WM) diseases relies heavily on the proper classification of patients into TCM syndrome types. The authors developed a data-driven method for solving the classification problem, where syndrome types were identified and quantified based on statistical patterns detected in unlabeled symptom survey data. The new method is a generalization of latent class analysis (LCA), which has been widely applied in WM research to solve a similar problem, i.e., to identify subtypes of a patient population in the absence of a gold standard. A well-known weakness of LCA is that it makes an unrealistically strong independence assumption. The authors relaxed the assumption by first detecting symptom co-occurrence patterns from survey data and used those statistical patterns instead of the symptoms as features for LCA. This new method consists of six steps: data collection, symptom co-occurrence pattern discovery, statistical pattern interpretation, syndrome identification, syndrome type identification and syndrome type classification. A software package called Lantern has been developed to support the application of the method. The method was illustrated using a data set on vascular mild cognitive impairment.

Aerobic Exercises for Cognition Rehabilitation following Stroke: A Systematic Review. J Stroke Cerebrovasc Dis 2016; 25:2780-2789. [PMID: 27554073 DOI: 10.1016/j.jstrokecerebrovasdis.2016.07.035] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Revised: 07/18/2016] [Accepted: 07/22/2016] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Cognitive impairments are highly prevalent in stroke survivors and can substantially affect their physical rehabilitation and quality of life. The management of these impairments currently remains limited, but increasing studies reported the effect of aerobic exercise on cognitive performance in patients suffering from stroke. The purpose of this review was to assess the effects of aerobic exercise on cognitive function following stroke. METHODS Seven electronic databases (China National Knowledge Infrastructure [CNKI], Chinese Science and Technology Periodical Database [VIP], Wanfang, China Biology Medicine disc [CBM], Science Citation Index [SCI], EMBASE, and PubMed) were searched from their inception to May 31, 2015, for the effects of aerobic exercise on cognitive ability compared to usual physical activity in stroke survivors. RevMan V5.3 (The Nordic Cochrane Centre) was used to analyze the data and to evaluate the methodological quality of the included studies. RESULTS Ten eligible studies including 394 participants were identified. Six studies showed that aerobic exercise significantly improved global cognitive ability in stroke survivors. Four studies reported aerobic exercise to be beneficial in improving memory, but only one showed statistical significance. Two studies investigated the effects of aerobic exercise on attention, and one showed a significant improvement. One study reported a significant benefit of aerobic exercise on visuospatial ability in stroke survivors. No adverse events were reported in the included studies. CONCLUSIONS Aerobic exercise may have a positive effect on improving global cognitive ability and a potential benefit on memory, attention, and the visuospatial domain of cognition in stroke survivors. However, further large, rigorously designed trials are needed to confirm these findings.

Abstract
Scrophularia kakudensis is an important medicinal plant with pharmaceutically valuable secondary metabolites. To develop a sustainable source of naturaceuticals with vital therapeutic importance, a cell suspension culture was established in S. kakudensis for the first time. Friable calli were induced from the leaf explants cultured on a Murashige and Skoog (MS) medium containing 3.0 mg·L−1 6-benzyladenine (BA) in a combination with 2 mg·L−1 2,4-dichlorophenoxy acetic acid (2,4-D). From the callus cultures, a cell suspension culture was initiated and the cellular differentiation was investigated. In addition, the effect of biotic elicitors such as methyl jasmonate (MeJa), salicylic acid (SA), and sodium nitroprusside (SNP) on the accumulation of secondary metabolites and antioxidant properties was demonstrated. Among the elicitors, the MeJa elicited the accumulation of total phenols, flavonoids, and acacetin, a flavonoid compound with multiple pharmaceutical values. Similarly, the higher concentrations of the MeJa significantly modulated the activities of antioxidant enzymes and enhanced the scavenging potentials of free radicals of cell suspension extracts. Overall, the outcomes of this study can be utilized for the large scale production of pharmaceutically important secondary metabolites from S. kakudensis through cell suspension cultures.

Abstract
The clinical therapeutics of traditional Chinese medicine (TCM) constitutes a complicated process which involves theory, diagnosis, and formula prescription with specific herbal dosage. Zhang Zhong-Jing’s classic work, Treatise on Febrile and Miscellaneous Diseases, has been influencing TCM practice for almost 2000 years. However, during this extended period of time in Chinese history, the Chinese weight measurement system experienced noticeable changes. This change in the weight measurement system inevitably, and perhaps even negatively, affected TCM herbal dosage determination and treatment outcome. Thus, in modern society, a full understanding of the accuracy of herbal dose selection has a critical importance in the TCM daily practice of delivering the best treatment to the patients suffering from different illnesses. In the 973 Project of the Chinese National Basic Research Program, expert consensus on classic TCM formula dose conversion has been reached based on extensive literature review and discussion on the dose–effect relationship of classic TCM formulas. One “liang” (两) in classic TCM formulas is equivalent to 13.8[Formula: see text]g. However, based on many TCM basic and clinical studies of variable herbal formula prescriptions and herbal drug preparations, the rule of one liang equals 13.8[Formula: see text]g should be adjusted according to different disease conditions. Recommended by the committee on TCM formula dose–effect relationship of the China Association of Chinese Medicine and the World Federation of Chinese Medicine Societies, the following expert consensus has been reached: (i) One liang converts to 6–9[Formula: see text]g for the severely and critically ill patients. (ii) One liang converts to 3–6[Formula: see text]g for the patients suffering from chronic diseases. (iii) One liang converts to 1–3[Formula: see text]g in preventive medicine. The above conversions should be used as a future TCM practice guideline. Using this recommended guideline should enhance the effectiveness of daily TCM practice.

Abstract
ReDuNing injection (RDN) is a patented traditional Chinese medicine, and the components of it were proven to have antiviral and important anti-inflammatory activities. Several reports showed that RDN had potential effects in the treatment of influenza and pneumonia. Though there were several experimental reports about RDN, the experimental results were not enough and complete due to that it was difficult to predict and verify the effect of RDN for a large number of human diseases. Here we employed multiscale model by integrating molecular docking, network pharmacology and the clinical symptoms information of diseases and explored the interaction mechanism of RDN on human diseases. Meanwhile, we analyzed the relation among the drug molecules, target proteins, biological pathways, human diseases and the clinical symptoms about it. Then we predicted potential active ingredients of RDN, the potential target proteins, the key pathways and related diseases. These attempts may offer several new insights to understand the pharmacological properties of RDN and provide benefit for its new clinical applications and research.

Abstract
Whether the combination of lamivudine (LAM) plus adefovir (ADV) de novo is more effective than entecavir (ETV) monotherapy in patients with HBV-associated decompensated cirrhosis is still controversial. We searched seven randomized controlled trials that included 411 patients in this meta-analysis. There are 205 and 206 patients in these two groups separately. The pooled risk ratio (RR) and mean difference (MD) were used to assess the treatment effects. ETV monotherapy significantly improved Child-Turcotte-Pugh (CTP) scores (MD = 0.33, 95%CI [0.21-0.44], P < .00001), and was associated with lower rates of serum creatinine increase compared LAM + ADV combination therapy (RR = 4.76, 95%CI [1.11-20.33], P = .04) at 48 weeks. The reduction of alanine aminotransferase (ALT) levels, HBV DNA levels, the rate of ALT normalization, undetectable HBV DNA, HBV e antigen (HBeAg) loss, HBeAg seroconversion and mortality were similar between the two groups. ETV is more effective than LAM + ADV in improving CTP scores at 48 weeks. Both of the LAM + ADV and ETV had similar efficacy in improving virological and biochemical parameters at 48 weeks of follow-up. Furthermore, use of these agents in decompensated HBV patients was generally safe and well tolerated at 48 weeks. However, the nephrotoxicity of ADV, and the potential adverse effects of ETV should be considered and monitored during prolonged therapy.
