RESUMO

INTRODUCTION: Colorectal adenoma (CRA) is a precancerous lesion for colorectal cancer. Endoscopic resection is the first-line treatment for CRA. However, CRA recurrence rate is high. This proposed study aims to determine if Chinese herbal medicine (CHM) reduces CRA recurrence. METHODS AND ANALYSIS: This project encompasses an observational, registry-based, cohort study and a nested qualitative study. The cohort study aims to include 364 postpolypectomy CRA participants at Guangdong Provincial Hospital of Chinese Medicine (GPHCM), China, with a follow-up phase of up to 1 year. In addition to routine care, these participants will receive a CHM treatment prescribed by experienced Chinese medicine (CM) clinicians. The CHM treatment encompasses CHM products and CHM formulae according to CM syndromes. The primary outcome is CRA recurrence rate at 1 year after enrolment. Secondary outcomes include characteristics of recurrent CRA, incidence of colorectal polyp (except for CRA), incidence of advanced CRA, incidence of colorectal cancer, improvement of gastrointestinal symptoms commonly seen in CRA patients, faecal occult blood test result, lipid level, fasting plasma glucose level, uric acid level, carcinoembryonic antigen, carbohydrate antigen 19-9, quality of life and safety evaluations. Logistic regression analysis will be used to explore the correlation between exposure and outcome. Qualitative interviews will be conducted among approximate 30 CRA patients from the cohort study and 10 CM practitioners in Department of Gastroenterology at GPHCM. Thematic analysis will be used to analyse qualitative data. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Human Research Ethics Committee (HREC) of GPHCM (YF2022-320-02) and registered at Royal Melbourne Institute of Technology (RMIT) HREC. The results will be disseminated in peer-reviewed journals and international academic conferences. TRIAL REGISTRATION NUMBER: ChiCTR2200065713.

RESUMO

At the time of the spread of the COVID-19 epidemic, blurred lung signs suggested by imaging examination are particularly common. Novel coronavirus infection is mainly caused by respiratory symptoms. In the early stage of imaging examination, multiple small patchy shadows or ground glass shadows and invasive shadows of both lungs are dominant. While the pulmonary involvement in Crohn's disease (CD) is rare and not widely reported. For CD patients, the pulmonary manifestations do not belong to its routine symptoms. The lung involvement of CD patients is difficult to attract clinicians' attention. If CD patients have vague lung manifestations but have no response to routine treatment, they should consider the respiratory diseases related to CD. We describe a rare case of granulomatous inflammation associated with Crohn's disease. The patient do not respond to conventional treatment. The final treatment plan was CD immunomodulatory therapy (oral corticosteroids and azathioprine). After treatment, a review of the lung CT showed focal fibrosis and significant improvement in the lung lesions. It suggests that CD related respiratory diseases should be considered when CD patients have abnormal lung manifestations that do not respond to conventional treatment.

RESUMO

Magnolol, a natural extract from magnolia officinalis, has received growing interest in its bioactive properties such as antioxidant, anti-inflammatory, and antibacterial activities. Nevertheless, there is little research on Magnolol in the treatment of parasitic infections currently. Eimeria tenella (E. tenella) infection causes damage to epithelial cells and cecal mucosa, resulting in increased intestinal permeability, which is pretty detrimental to the balance of the intestinal microenvironment. However, at present, in the treatment of chicken coccidiosis, the abuse of antibiotics is quite serious, which has brought losses and harms to the chicken farming industry that cannot be ignored. In this study, based on the excellent antioxidant and anti-inflammatory properties of Magnolol, we proved that it does have a desirable therapeutic potential on chicks infected with E. tenella. Actually, the results showed that the clinical symptoms of the chicks infected with E. tenella were relieved and their growth performance was restored by Magnolol treatment. Furthermore, Magnolol improved the antioxidant and anti-inflammatory properties of chicks. Meanwhile, the Magnolol reversed the imbalance of the intestinal microbiota of sick chicks, which recovered the diversity, promoted the potential beneficial bacteria, and inhabited the potential pathogenic bacteria. Overall, Magnolol may be an alternative to chemical drugs that are effective in treating E. tenella infections.

RESUMO

Background: Non-alcoholic fatty liver disease (NAFLD) is the global most common chronic liver disease. Non-alcoholic steatohepatitis (NASH), an inflammatory subtype of NAFLD, has been shown to significantly increase the risk of colorectal adenoma (CRA). Therefore, from the perspective of bioinformatics analysis, the potential mechanisms of NASH/NAFLD-CRA can be explored. Methods: In this study, we screened the differentially expressed genes (DEGs) and core effect pathways between NASH and CRA by analyzing the single-cell data of CRA patients and the high-throughput sequencing data (GSE37364 and GSE89632) in the online database. We screened therapeutic targets and biomarkers through gene function classification, pathway enrichment analysis, and protein-protein interaction network analysis. In terms of single cell data, we screened the core effect pathway and specific signal pathway of cell communication through cell annotation and cell communication analyses. The purpose of the study was to find potential biomarkers, therapeutic targets, and related effect pathways of NASH-CRA. Results: NASH-CRA comorbidities were concentrated in inflammatory regulation-related pathways, and the core genes of disease progression included IL1B, FOSL1, EGR1, MYC, PTGS2, and FOS. The results suggested the key pathway of NASH-CRA might be the WNT pathway. The main cell signal communication pathways included WNT2B - (FZD6 + LRP5) and WNT2B - (FZD6 + LRP6). The send-receive process occurred in embryonic stem cells. Conclusions: The core genes of NASH-CRA (FOS, EGR1, MYC, PTGS2, FOSL1, and IL1B) may participate in inflammation and immune responses through up-regulation in the process of disease occurrence, interfering with the pathophysiological process of CRA and NASH. NASH-CRA produces cell signal communication in the WNT pathway sent by WNT2B and received by FZD6, LRP5, and LRP6 in embryonic stem cells. These findings may help formulate early diagnosis and treatment strategies for CRA in NAFLD/NASH patients, and further explore corresponding prognostic markers and potential approaches. The significance of scRNA-seq in exploring tumor heterogeneity lies in promoting our understanding of the expression program of tumor related genes in tumor development patterns. However, the biggest challenge is that this analysis may miss out on some biologically significant gene expression programs.

RESUMO

BACKGROUND: Infliximab is an effective drug for the treatment of Crohn's disease. As a rare and unique adverse effect of infliximab, hypertension should be paid enough attention in clinical work. At present, there is no relevant case report. We report a case of a 38-year-old man with Crohn's disease who had no history of hypertension and developed hypertension symptoms during infliximab treatment. CASE DESCRIPTION: The patient was treated with 5 mg/kg infliximab on August 27, 2020. From August 27, 2020 to October 20, 2020, the patient underwent 3 treatment sessions. After each injection of infliximab, the patient's blood pressure became elevated, accompanied by dizziness and symmetrical numbness of both lower limbs. Amlodipine benazepril tablets were given orally to control blood pressure. Under close monitoring, 5 mg/kg infliximab was used again. After 10 min of infusion, blood pressure rose to 160/118 mmHg. Infusion was discontinued immediately, after which blood pressure decreased to normal. Adrenal computed tomography did not indicate adrenal hyperplasia or space occupying lesions, and the detection of hypertension related indicators in standing and supine position was abnormal. Since follow up, the patient has stopped using infliximab and has had no hypertension-related symptoms, even without antihypertensives. Measured blood pressure was within the normal range. CONCLUSIONS: Hypertension, as one of the rare adverse reactions of infliximab in the treatment of Crohn's disease, should be paid enough attention.

RESUMO

Background: Intestinal spasm and peristalsis during colonoscopy are common but undesirable phenomena, which can easily lead to a missed diagnosis of colorectal polyps and other diseases, and antispasmodic drugs can have adverse side effects. Previous studies find that acupuncture can regulate abnormal gastrointestinal motility. But evidence quality is low and limited at present, and high-quality studies are required. So this study sought to explore the efficacy and safety of acupuncture in inhibiting colonic spasm during endoscopy. Methods: In this prospective, single-blinded, randomized controlled trial, 54 patients experiencing intestinal spasms during colonoscopy were randomly assigned to receive either acupuncture of the bilateral Hegu (LI 4) and Neiguan (PC 6) points (n=27) or sham acupuncture (n=27). The sham points were located 1 cm above the proximal end of the true points and had no known function. The primary outcome was the latency time to colonic spasm suppression, and the secondary outcomes were the duration of colonic spasm suppression, the proportion of patients with rebound spasms within 5 minutes, and adverse events related to acupuncture-related side effects. Results: A total of 54 patients were eligible, and 27 in each group. There was no significant difference in the background characteristics of the patients in the 2 groups. The latency time to spasm suppression of the treatment group was significantly shorter than that of the sham control group (acupuncture: 32.00 s vs. sham: 82.00 s; P<0.001). However, the duration of colonic spasm suppression was similar (acupuncture: 300 s vs. sham: 268 s; P=0.142). No rebound spasms were observed in the treatment group but rebound spasms were observed in 3 patients in the sham control group (acupuncture: 0% vs. sham: 11.1%; P=0.236). No adverse events were observed in either group. Conclusions: Acupuncture of the bilateral Hegu (LI 4) and Neiguan (PC 6) points can shorten the latency time to spasm suppression, and may be used to suppress colonic spasm during colonoscopy.

RESUMO

Robust ceramic membranes presented attractive features of easy cleaning and excellent stability compared to polymeric membranes. Nevertheless, their inherent relationships between the membrane microstructures and separation properties are not completely clear. In this work, we established a quantitative structure-property model using α-Al2O3 membrane on account of the theory of filtrated cake to predict the effects of membrane structure-controlled factors (i.e., α-Al2O3 particle size and layer thickness) on separation performances (i.e., solute rejection and water permeance). The simulation results show that membrane pore size mainly depends upon α-Al2O3 particle size rather than the layer thickness. When the microstructure of top layer in a double-layer asymmetric ceramic membrane is fixed, there exists optimum particle size and layer thickness that constitute the support layer to achieve maximum water permeance. For a triple-layer ceramic membrane, a similar matching relationship exists between top layer and intermediate layer, indicating that the intermediate layer has a vital role in determining water permeance. While the bottom layer has little effect on overall separation property. Finally, the upper-bound tradeoff relationship between permeance and selectivity is further established for the α-Al2O3 membrane. This study reveals the structure-property relationship of ceramic membrane and provides insights into performance enhancement.

RESUMO

Background: The early diagnosis of colorectal cancer (CRC) is very important for the prognosis of patients. It has been suggested that the cytosine-phosphate-guanine (CpG) island of itga4 is highly methylated in colorectal adenoma cell lines AA/C1, Vaco 235 and so on. So the purpose of our study is to explore the diagnostic accuracy and related mechanism of integrin alpha 4 (ITGA4) in early CRC. Methods: The Cancer Genome Atlas (TCGA) database was used to analyze the relationship between the expression of ITGA4 and the clinicopathological features and the overall survival rate of the disease. Then, the interaction protein and function enrichment region of ITGA4 were analyzed. Finally, the infiltration of related immune cells was analyzed. Results: Compared with normal tissues, the expression of ITGA4 in colon adenocarcinoma and rectum adenocarcinoma (COAD-READ) tumor tissues was lower (P<0.05). The overall survival rate of COAD-READ patients with low ITGA4 level was lower than that of patients with high ITGA4 expression (P<0.05), and expression of ITGA4 had a more significant predictive effect in the early stage of tumor development. The results of protein network and enrichment analysis suggested that ITGA4 was closely related to ITGB2 and might be involved in the inflammatory reaction and inflammatory tumor transformation process in the carcinogenesis of inflammatory bowel disease (IBD), which was verified by another independent sequence. In terms of immune infiltration, the expression level of ITGA4 was positively correlated with the infiltration level of intestinal macrophages (Th17), immature dendritic cells (IDC), dendritic cells (DC), mast cells, and eosinophils in COAD-READ, and significantly negatively correlated with CD56bright natural killer (NK) cells. Conclusions: The low expression of ITGA4 was related to the poor prognosis of COAD-READ. Findings showed that ITGA4 might participate in the inflammatory reaction and inflammatory tumor transformation process in the carcinogenesis of IBD, and that ITGA4 was related to the infiltration of immune cells, macrophages, syndactyls, and CD56bright NK cells. The expression of ITGA4 could be used as an early predictor of CRC. However, the mechanism of ITGA4 promoting tumor progression in CRC still needs further research.

RESUMO

Staphylococcus aureus continues to be one of the most important pathogens capable of causing a wide range of infections in different sites of the body in humans and livestock. With the emergence of methicillin-resistant strains and the introduction of strict laws on antibiotic usage in animals, antibiotic replacement therapy has become increasingly popular. Previous studies have shown that Portulaca oleracea L. extract exerts a certain degree of bacteriostatic effect, although the active ingredients are unknown. In the present study, the antibacterial activity of the organic acid of P. oleracea (OAPO) against S. aureus was examined using a series of experiments, including the minimum inhibitory concentration, growth curve, and bacteriostasis curve. In vitro antibacterial mechanisms were evaluated based on the integrity and permeability of the cell wall and membrane, scanning electron microscopy, and soluble protein content. A mouse skin wound recovery model was used to verify the antibacterial effects of OAPO on S. aureus in vivo. The results showed that OAPO not only improved skin wound recovery but also decreased the bacterial load in skin wounds. Moreover, the number of inflammatory cells and cytokines decreased in the OAPO-treated groups. In summary, this study reports a botanical extract that can inhibit S. aureus in vitro and in vivo, indicating the potential use of OAPO to prevent and control S. aureus infection in the near future.

RESUMO

The tumor prescriptions contained in Dictionary of Tumor Formulas, Compendium of Good Tumor Formulas, Chinese Pharmacopoeia, Ministry of Health Drug Standards for Chinese Medicine Formulas and National Compilation of Standards for Proprietary Chinese Medicines were selected and organized to construct a database for tumor prescriptions, and the data mining techniques were applied to investigate the prescription regularity of colorectal cancer prescriptions. The formula data were extracted after screening in strict accordance with the inclusion and exclusion criteria, and were then analyzed with Microsoft Excel 2010 for frequency statistics, Apriori block provided by SPSS Clementine 12.0 software for correlation rule analysis, and arules and arulesViz packages in R 4.0.2 software for correlation rule visualization. In addition, SPSS 18.0 software was used for cluster analysis and factor analysis, in which cluster analysis was performed by Ochiai algorithm with bicategorical variables in systematic clustering method and factor analysis was performed mainly with principal component analysis. A total of 285 prescriptions were included in the statistical analysis, and the frequency statistics showed that 43 herbs had been used more than 16 times. The association rules analysis showed that 26 high-frequency me-dicine pair rules were obtained, and the association rules for those dispelling evil spirits, strengthening the body, resolving stasis, dispelling dampness, etc. were visualized. In the cluster analysis, we generated a dendrogram from which 7 groups of traditional Chinese medicines with homogeneity were extracted. 10 common factors were obtained in the factor analysis. The types of herbal medicines involved in the colorectal cancer prescription included anti-cancer antidotes, strengthening and tonifying medicines, blood-regulating medicines, and expectorant medicines, corresponding to the treatment for eliminating evil spirits, strengthening, resolving stasis, and expectorating dampness. The prescriptions for anti-cancer detoxification were normally based on the pairs composed of Scutellaria barbata-Hedyotis diffusa and Sophora flavescens, Sargentodoxa cuneata, S. barbata, often combined with stasis relieving drug and dampness eliminating drug, reflecting the characteristics of treatment for both toxicity and stasis, dampness and toxicity simultaneously. The prescriptions for strengthening the righteousness and tonifying the deficiency were composed of Astragalus membranaceus and Atractylodes macrocephala mainly, exerting the effect of benefiting Qi, strengthening the spleen and drying dampness, tonifying kidney and essence, tonifying blood and invigorating blood. Meanwhile, anti-cancer detoxification medicines shall be reduced as much as possible. The compatibility of the medicines for the intestinal tract reflected the principle of using the right medicine for the right condition and eliminating evil spirits or strengthening the body, as appropriate.

RESUMO

BACKGROUND: With the changes in lifestyle and diet, the incidence and mortality of colorectal cancer (CRC) is increasing in China. CRC mainly develops from colorectal adenomas (CRAs). There is a lack of chemopreventative drugs with definite efficacy for CRAs. Tiaochang Xiaoliu Decoction (TXD) was developed by Professor Yunjian Luo and has been used clinically over the last ten years for the prevention of CRA recurrence. To facilitate its clinical use, TXD was further standardized and produced as "Tiaochang Xiaoliu Decoction Granules (TXDG)". A study was designed to investigate the preventive effects of TXDG on the recurrence of CRA. METHODS: A randomized, double-blinded, controlled, and multi-center experiment is proposed to assess the effectiveness and safety of TXDG. Patients with CRAs (after complete polypectomy under colonoscopy) will be randomly divided into two groups, one will be treated with TXDG (the TXDG group) and the other will be treated with a TXDG mimetic agent (the TXDG mimetic group). The patients will be treated for 6 months and followed up for 3 years. Follow-up colonoscopy is expected to be carried out within 1 to 3 years after the baseline examinations. The primary outcome measure is adenoma detection rate within 1 to 3 years. The secondary outcome measures are the number, location, and pathology of the adenomas, and the polyp detection rate. DISCUSSION: Reliable objective evidence will be provided to evaluate the efficacy and safety of TXDG as an accessorial therapy for CRA occurrence in post-polypectomy patients. TRIAL REGISTRATION: ChiCTR2000035257.

RESUMO

In this study, Honghua Injection, Danshen Injection, Shenkang Injection, Shuxuetong Injection, Lulutong Injection, Shenxiong Glucose Injection and Chuanxiong Injection were compared for their clinical efficacy on chronic renal insufficiency by using the method of network Meta-analysis, with Western medicine as the common reference. The randomized controlled trial(RCT) of Hong-hua Injection, Danshen Injection, Shenkang Injection, Shuxuetong Injection, Lulutong Injection, Shenxiong Glucose Injection and Chuanxiong Injection for the treatment of chronic renal insufficiency were obtained by computer-based retrieval. The literature quality was evaluated by using the method in Cochrane Reviewer's Handbook 5.1 after independent screening of the included literature by two reviewers. The RJAGS package and GEMTC package of RevMan 5.3, GEMTC software, R software were used for statistical analysis to compare and sort the different injections in terms of efficacy. A total of 6 197 patients with chronic renal failure were included in 79 RCTs, involving 8 treatment measures. The effective rates of conventional treatment combined with Shenxiong Injection(OR=3.55, 95%CI[1.98, 6.37], P<0.000 1), Honghua Injection(OR=3.77, 95%CI[2.45, 5.81], P<0.000 01), Shuxuetong Injection(OR=6.71, 95%CI[3.30, 13.65], P<0.000 01) and Shenkang Injection(OR=4.14, 95%CI[3.42, 5.03], P<0.000 01) were all better than that in control group, and the effective rate of Honghua Injection combined with conventional treatment(OR=3.89, 95%CI[1.73, 8.74], P=0.001) was better than that in Danshen Injection combined with conventional treatment, all with statistically significant differences. By comprehensive comparison, Shuxuetong Injection, Honghua Injection and Shenkang Injection combined with Western medicine had good clinical effect on the effective rate, serum creatinine reduction and urea nitrogen reduction in patients with chronic renal insufficiency. However, due to the relatively low quality of the included literature, the conclusion has yet to be verified clinically.

RESUMO

BACKGROUND: Artificial intelligence (AI) is used to solve the problem of missed diagnosis of polyps in colonoscopy, which has been proved to improve the detection rate of adenomas. The aim of this review was to evaluate the diagnostic performance of AI-assisted detection and classification of polyps in colonoscopy. METHODS: The literature search was undertaken on 4 electronic databases (PubMed, Web of Science, Embase, and Cochrane Library). The inclusion criteria were as follows: studies reporting AI-assisted detection and classification of polyps; studies containing patients, images, or videos receiving AI-assisted diagnosis; studies which included AI-assisted diagnosis and reported classification based on histopathology; and studies providing accurate diagnostic data. Non-English language studies, case-reports, reviews, meeting abstracts and so on were excluded. The Quality Assessment of Diagnostic Accuracy Studies-2 scale was used to evaluate the quality of literature and the Stata 13.0 software was used to perform meta-analysis. RESULTS: Twenty-six articles were included with all of medium quality. Meta-analysis showed none of literature had any obvious publication bias. The application of AI in detection of colorectal polyps achieved a sensitivity of 0.95 [95% confidence interval (CI): 0.89-0.98] and an area under the curve (AUC) of 0.79 (95% CI: 0.79-0.82). In the AI-assisted classification, the sensitivity was 0.92 (95% CI: 0.88-0.95) with a specificity of 0.82 (95% CI: 0.71-0.89) and an AUC of 0.94 (95% CI: 0.92-0.96). For the classification of diminutive polyps, the AI-assisted technique yielded a sensitivity of 0.95 (95% CI: 0.94-0.97), a specificity of 0.88 (95% CI: 0.74-0.95), and an AUC of 0.97 (95% CI: 0.95-0.98). For AI-assisted classification under magnifying endoscopy, the sensitivity was 0.954 (95% CI: 0.92-0.96) with a specificity of 0.95 (95% CI: 0.80-0.99) and an AUC of 0.97 (95% CI: 0.95-0.98). DISCUSSION: The AI-assisted technique demonstrates impressive accuracy for the detection and characterization of colorectal polyps and can be expected to be a novel auxiliary diagnosis method. Our study has inevitable limitations including heterogeneity due to different AI systems and the inability to further analyze the specificity and sensitivity of AI for different types of endoscopes.

RESUMO

Calcified macroalgae play an important role in the settlement and metamorphosis of invertebrate larvae in coral reef ecosystems. However, little is known about the algal-associated bacterial communities and their effects on larval settlement. In this study, the responses of larvae of the coral Pocillopora damicornis to calcified algae (Porolithon onkodes, Halimeda cylindracea, Halimeda opuntia and Amphiroa fragilissima) were evaluated. The results revealed that Por. onkodes and H. cylindracea significantly enhanced the rates of settlement and metamorphosis, whereas fewer larvae settled on Am. fragilissima and H. opuntia. Amplicon pyrosequencing of the V3-V4 region of 16S rDNA was applied to investigate the relationship between algal bacterial community and larval settlement. Principal coordinates analysis demonstrated that the bacterial community composition of H. opuntia was more similar to that of Am. fragilissima, but clearly distinct from those of H. cylindracea and Por. onkodes. Furthermore, the relative abundances of bacteria were highly diverse among different algae. H. opuntia had higher percentages of Thalassobius, Pelagibius and SM1A02, whereas the abundances of Mycoplasma and Suttonella were significantly higher in H. cylindracea than other algae. Our results showed that larval settlement/metamorphosis was strongly correlated with the bacterial community composition and with the relative abundance of a few operational taxonomic units.

RESUMO

BACKGROUND: Cerebral palsy (CP) is a common disability in children featured with pathological gait and limb function limitation due to muscle weakness. Improving limb function and quality of life is currently considered to be highlighted. Physiotherapy is a chief component of rehabilitation for children with CP, correcting gait and improve walking capacity through muscle strength training. Standard rehabilitation programs for CP have not been determined. Core stability training (CST), which coordinates limb balance via trunk control, is widely used in sports competition. And it is gradually introduced into the rehabilitation of children with cerebral palsy with a positive impact on the patients' gait performance. By screening published literatures, this study aims to conduct a meta-analysis to systematically evaluate the effectiveness and safety of CST in gait of children with CP. METHODS: Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on CST in the treatment of children with CP were searched from 6 databases. Moreover, the reference lists of conference papers and included literatures will be manually searched to avoid omissions. Literature screening and data extraction were performed independently by 2 researchers. RCTs carry out the risk of bias analysis evaluation from seven aspects through the Cochrane Collaboration's risk of bias tool. Fixed or random effect model will be performed to analyze the outcomes. When higher heterogeneity occurs (I > 50%), the sensitivity or subgroup analysis will also be conducted to find potential factors. And the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach is used for assessing the quality of evidence. RESULTS: The study will evaluate the effect of CST on gait of children with CP from multiple outcomes, including walking speed, endurance, stride length, and safety. CONCLUSION: Based on evidence-based medicine, the conclusion of this study can demonstrate the effectiveness and safety of CST in gait correction for children with CP.

RESUMO

This study utilized physical adsorption and filtration of carbon nanotubes (CNTs) and laccases to fabricate biomimetic dynamic membrane (BDM) for the advanced treatment of dye wastewater. In BDM, the adsorption, enzymatic degradation and membrane separation demonstrated a synergism effect on pollutant removal. At first, the fabrication methods of BDM were investigated, and the mixed filtration for laccases and CNTs showed a better performance than the stepwise filtration. Furthermore, the operation parameters of BDM, including CNTs and laccase loading amounts, dye concentration, agitation speed and transmembrane pressure (TMP), were studied. Suitable CNTs and laccase amounts could reduce filtration resistance and increase catalysis efficiency, while moderate TMP and agitation speed were in favor of boosting the BDM structure for catalysis and permeability. Optimized operation parameters (CNT loading amount = 20 g m-2, laccase loading amount = 74.6 g m-2, agitation speed = 100 rpm, and TMP = 1.0 bar) sustained a high removal rate, and the flux was over 120 L m-2 h-1, even for 7 operation cycle' tests. BDM exhibited an excellent dye removal rate, stable flux and great antifouling capacity, on the ground that adsorption saturation and foulant may be alleviated "online and in-situ" by the enzymatic degradation. Afterwards, the bionic layer on BDM, after absorption saturation and catalyst deactivation, could be eliminated rapidly by carrying out a simple backwash cleaning operation, then a new one could be fabricated immediately. Therefore, BDM is a good candidate for functional membrane materials in future water treatment.

RESUMO

There is a large amount of studies surrounding the usage of agro-industrial waste (AIW) for the adsorptions of organic pollutants (dyes) and inorganic pollutants (heavy metals) in water/wastewater. This method is normally treated as an alternative approach to the conventional water/wastewater treatment. However, there are some increasing interests for investigators to identify novel adsorption materials for pollutants removal. It is particularly noteworthy that most AIW wastes are not currently used at the original state, but modified in a variety of ways to reinforce the porosity and adsorption surface area of the material. Nanostructuring, activation, carbonization, and grafting are some common modification technologies of agricultural waste adsorbents. Besides, the characteristic, preparation and application of adsorbents from various industrial wastes, including natural materials and biosorbents, were summarized. Additionally, the challenges and perspectives for future researches of waste-derived adsorbents were studied. This review provides an important insight on using AIWs as precursor materials for preparing adsorbents in water/wastewater treatment.
