Pre-procedural cleansing of the bowel can maximize the effectiveness and efficiency of colonoscopy.Yet,efficacy of the current gold standard colonic preparation method-high-volume oral administration of purgative agents 12-24 h prior to the procedure-is limited by several factors,such as patient compliance(due to poor palatability and inconvenience of the dosing regimen)and risks of complications(due to drug interactions or intolerance).Attempts to resolve these limitations have included providing adjunctive agents and methods to promote the colonic cleansing ability of the principal purgative agent,with the aim of lessening unpleasant side effects(such as bloating)and reducing the large ingested volume requirement.Several promising adjunctive agents are bisacodyl,magnesium citrate,senna,simethicone,metoclopramide,and prokinetics,and each are being investigated for their potential.This review provides an up to date summary of the reported investigations into the potencies and weaknesses of the key adjuncts currently being applied in clinic as supplements to the traditional bowel preparation agents.While the comparative analysis ofthese adjuncts showed that no single agent or method has yet achieved the goal of completely overcoming the limitations of the current gold standard preparation method,they at least provide endoscopists with an array of alternatives to help improve the suboptimal efficacy of the main cleansing solutions when used alone.To aid in this clinical endeavor,a subjective grade was assigned to each adjunct to indicate its practical value.In addition,the systematic review of the currently available agents and methods provides insight into the features of each that may be overcome or exploited to create novel drugs and strategies that may become adopted as effective bowel cleansing adjuncts or alternatives. 展开更多

BACKGROUND Perinatal depression affects 10%-20%of pregnant women and subsequently influences maternal health and fetal development.Concerns over the safety of antidepressants during pregnancy have prompted the exploration of nutritional interventions as adjunct therapies.This study evaluated the impact of combining preconception and prenatal supplementation with myo-inositol,probiotics,and trace elements on mood,quality of life,and fetal development in depressed mothers.This retrospective cohort study included 314 pregnant women who were diag-nosed with mild to moderate depression,as determined by a Zung self-rating depression scale score of less than 69.The participants were divided into an intervention group(n=161)receiving myo-inositol,probiotics,and trace elements and a control group(n=153)without supplementation.Supplementation comm-enced 3 months before conception and continued through pregnancy.Psychiatric symptoms and quality of life were evaluated using the positive and negative affect schedule-now,state-trait anxiety inventory,Patient Health Ques-tionnaire-8,and World Health Organization Quality of life Assessment:Brief Version scales preconception and postpartum.Fetal development metrics were assessed via ultrasound,and neonatal outcomes were recorded.RESULTS The intervention group presented significant reductions in gestational diabetes mellitus(13.04%vs 23.53%,P=0.016)and gestational hypertension(3.73%vs 9.15%,P=0.049).Higher levels of inositol,iron,zinc,and probiotics were observed near term in the intervention group.Postpartum mood assessments indicated lower anxiety and depression scores for the intervention group,with significant improvements in the positive and negative affect schedule-now(P=0.002),trait anxiety(P=0.002),and Patient Health Questionnaire-8(P=0.018)scores.The World Health Organization Quality of life Assessment:Brief Version scores improved in the psychological(P=0.041)and environmental(P=0.009)domains postpartum.Fetal biparietal diameter and femoral length were greater in the intervention group alongside better neonatal body length and reduced neonatal unit admissions(2.48%vs 7.84%,P=0.031).CONCLUSION Combined supplementation with myo-inositol,probiotics,and trace elements from preconception through pregnancy may reduce pregnancy-related complications,enhance mood and quality of life,and improve fetal growth metrics. 展开更多

Microbial infection is a principal etiological factor in pulp and periapical diseases,necessitating effective root canal therapy(RCT)for thorough decontamination of the root canal system.However,conventional mechanical and chemical preparation methods remain inadequate,often leaving significant portions of the canal uncleaned and contributing to persistent infection.The advent of erbium laser-assisted chemical preparation has demonstrated significant potential in enhancing root canal disinfection through advanced fluid dynamics mechanisms,particularly cavitation and photoacoustic streaming.This review explores the fundamental principles governing fluid dynamics in erbium laser-assisted irrigation,with a focus on primary and secondary cavitation effects.The interaction between erbium laser energy and water generates vapor bubbles that induce dynamic fluid movement,enhancing the penetration and distribution of irrigants deep within the root canal system.Key factors influencing fluid dynamics intensity,including laser parameters,working tip design,and water medium confinement,are critically analyzed.Furthermore,recent advancements such as Photon-Initiated Photoacoustic Streaming(PIPS),Photoacoustic Synchronized Transients(PHAST),and Shock Wave Enhanced Emission Photoacoustic Streaming(SWEEPS)are reviewed in the context of their ability to improve fluid motion and irrigation efficacy.While these laser-assisted techniques offer promising improvements over traditional methods,challenges remain in optimizing energy parameters and mitigating the constraints imposed by confined root canal environments.Future research should focus on refining fluid dynamics models and conducting clinical studies to validate the efficacy of these innovations.This review aims to provide a comprehensive overview of current developments in fluid dynamics research related to erbium laser-assisted chemical preparation,offering insights into its potential as an advanced modality for root canal disinfection. 展开更多

BACKGROUND Demineralized bone matrix(DBM)is a commonly utilized allogenic bone graft substitute to promote osseous union.However,little is known regarding outcomes following DBM utilization in foot and ankle surgical procedures.AIM To evaluate the clinical and radiographic outcomes following DBM as a biological adjunct in foot and ankle surgical procedures.METHODS During May 2023,the PubMed,EMBASE and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following DBM for the management of various foot and ankle pathologies.Data regarding study characteristics,patient demographics,subjective clinical outcomes,radiological outcomes,complications,and failure rates were extracted and analyzed.In addition,the level of evidence(LOE)and quality of evidence(QOE)for each individual study was also assessed.Thirteen studies were included in this review.RESULTS In total,363 patients(397 ankles and feet)received DBM as part of their surgical procedure at a weighted mean follow-up time of 20.8±9.2 months.The most common procedure performed was ankle arthrodesis in 94 patients(25.9%).Other procedures performed included hindfoot fusion,1st metatarsophalangeal joint arthrodesis,5th metatarsal intramedullary screw fixation,hallux valgus correction,osteochondral lesion of the talus repair and unicameral talar cyst resection.The osseous union rate in the ankle and hindfoot arthrodesis cohort,base of the 5th metatarsal cohort,and calcaneal fracture cohort was 85.6%,100%,and 100%,respectively.The weighted mean visual analog scale in the osteochondral lesions of the talus cohort improved from a pre-operative score of 7.6±0.1 to a post-operative score of 0.4±0.1.The overall complication rate was 27.2%,the most common of which was non-union(8.8%).There were 43 failures(10.8%)all of which warranted a further surgical procedure.CONCLUSION This current systematic review demonstrated that the utilization of DBM in foot and ankle surgical procedures led to satisfactory osseous union rates with favorable wound complication rates.Excellent outcomes were observed in patients undergoing fracture fixation augmented with DBM,with mixed evidence supporting the routine use of DBM in fusion procedures of the ankle and hindfoot.However,the low LOE together with the low QOE and significant heterogeneity between the included studies reinforces the need for randomized control trials to be conducted to identify the optimal role of DBM in the setting of foot and ankle surgical procedures. 展开更多

The sphere of artificial intelligence(AI)is ever expanding.Applications for clinical practice have been emerging over recent years.Although its uptake has been most prominent in endoscopy,this represents only one aspect of holistic patient care.There are a multitude of other potential avenues in which gastrointestinal care may be involved.We aim to review the role of AI in colorectal cancer as a whole.We performed broad scoping and focused searches of the applications of AI in the field of colorectal cancer.All trials including qualitative research were included from the year 2000 onwards.Studies were grouped into pre-operative,intra-operative and post-operative aspects.Preoperatively,the major use is with endoscopic recognition.Colonoscopy has embraced the use for human derived classifications such as Narrow-band Imaging International Colorectal Endoscopic,Japan Narrow-band Imaging Expert Team,Paris and Kudo.However,novel detection and diagnostic methods have arisen from advances in AI classification.Intra-operatively,adjuncts such as image enhanced identification of structures and assessment of perfusion have led to improvements in clinical outcomes.Post-operatively,monitoring and surveillance have taken strides with potential socioeconomic and environmental savings.The uses of AI within the umbrella of colorectal surgery are multiple.We have identified existing technologies which are already augmenting cancer care.The future applications are exciting and could at least match,if not surpass human standards. 展开更多

In our editorial,we want to comment on the article by Stefanolo et al titled“Effect of Aspergillus niger prolyl endopeptidase in patients with celiac disease on a long-term gluten-free diet”.Celiac disease is an immune-mediated disorder triggered by dietary gluten in genetically predisposed individuals.Although avoiding gluten can permit patients to live symptom-free,ongoing voluntary or involuntary exposure to gluten is common and associated with persistent villous atrophy in small bowel mucosa.As villous atrophy predisposes patients to life threatening complications,such as osteoporotic fractures or malignancies,therapeutic adjuncts to gluten-free diet become important to improve patients’quality of life and,if these adjuncts can be shown to improve villous atrophy,avoid complications.Oral administration of enzyme preparations,such as endopeptidases that digest gluten and mitigate its antigenicity to trigger inflam-mation,is one clinical strategy under investigation.The article is about the utility of one endopeptidase isolated from Aspergillus niger.We critique findings of this clinical trial and also summarize endopeptidase-based as well as other strategies and how they can complement gluten-free diet in the management of celiac disease. 展开更多

Constant escalations in the number of diabetics worldwide and the failure of conventional therapy to restore normoglycemia without adverse effects,in spite of tremendous strides in modern medicine,calls for naturopathy and alternative medicine.Because diabetes is multi-factorial and has secondary complications,prevention of hyperglycemia is the central dogma for its management.To date,no oral hypoglycemic exists which can achieve tight glycemic control without side effects.Dietary adjuncts,lifestyle interventions and a resurgence of interest in phyto-therapy have consequently gained ground.Natural hypoglycemics have attracted attention due to ease of incorporation in everyday diet,affordability,less adverse effects,and long term safety.Ethno botanical literature reports more than 800 anti-diabetic plants species.Eucalyptus is well represented in the Aboriginal Pharmacopoeias for its various pharmacological activities.Its hot aqueous decoction has been used as a hypoglycemic in various regions of world.This editorial attempts to summarize the data on the hypoglycemic potential of the different eucalyptus species,highlight the value of its natural biomolecules for the prophylaxis and treatment of type2 diabetes,describe their mechanistic actions,shed light on the posology and safety aspects of eucalyptusand assess its applicability as a reinforcement to currently used therapy. 展开更多

We call it separated condition. This is a condition on topology OX equivalent to the T O space X being Hausdorff. The class of separated frames includes that of strong Hausdorff frames and that of S frames. We shall show that the class of separated frames is a class closed under the formation of coproducts and subspaces, and the space Fil( L ) is Hausdorff for any separated frame L . Therefore there is a contravariant adjunction between the category TOP 2 of Hausdorff topological spaces and the category FRAM 2 of separated frames. 展开更多

The tenth BRICS Summit was held in Johannesburg,South Africa in 2018,which attracted attention from the whole world.Especially,it is of great importance to the BRICS nations,for it is the first ten years of BRICS,which marks its growth.Meanwhile,this year the Trump administration imposed more strict policies on protectionism.Particularly,the trade war between China and the United States is so intensive.China,as the core member of BRICS has great clout on BRICS,so the trade war between China and US also arouse a heat discussion among the BRICS nations.During the Summit,CGTN invited experts from the five BRICS nations to discuss related topics.Systemic Functional Linguistics,as one of the most influential branches of Linguistics,was firstly established by M.A.K.Halliday,and it has been greatly developed over the past decades.Interpersonal meaning is one of the three meta-functions,which focuses on how addressers use language to communicate,establish and maintain relationships with addressees,and express their opinions.Mood and modality are two basic resources to the realization of interpersonal meaning.Mood is used to represent the interaction of the language users,while modality reflects the utterers’attitudes and judgments.The paper discusses the three aspects of modality:modal operators,modal adjuncts and metaphors of modality.The paper applies the modality system to the analysis of the transcript of BRICS TALK.The author selects the experts’speeches on the trade war between China and US as the data.The research questions are as followed:(1)the characteristics of the modality resources appeared in their talks;(2)the BRICS nations attitudes and stance on trade war and America’s protectionism. 展开更多

AIM:To investigate the adjunct anticancer effect of Astragalus polysaccharides in H22 tumor-bearing mice.METHODS:To establish a solid tumor model,5.0 × 10 6 /mL H22 hepatoma cells were inoculated subcutaneously into the right armpit region of Kunming mice(6-12 wk old,18-22 g).When the tumors reached a size of 100 mm 3,the animals were treated as indicated,and the mice were randomly assigned to seven groups(n = 10 each).After ten days of treatment,blood samples were collected from mouse eyes,and serum was harvested by centrifugation.Mice were sacrificed,and the whole body,tumor,spleen and thymus were weighed immediately.The rate of tumor inhibition and organ indexes were calculated.The expression levels of serum cytokines,P-glycoprotein(P-GP) and multidrug resistance(MDR) 1 mRNA in tumor tissues were detected using enzyme-linked immunosorbent assay,Western blotting,and quantitative myeloid-derived suppressor cells reverse transcription-polymerase chain reaction,respectively.RESULTS:The tumor inhibition rates in the treatment groups of Adriamycin(ADM) + Astragalus polysaccharides(APS)(50 mg/kg),ADM + APS(100 mg/kg),and ADM + APS(200 mg/kg) were significantly higher than in the ADM group(72.88% vs 60.36%,P = 0.013;73.40% vs 60.36%,P = 0.010;77.57% vs 60.36%,P = 0.001).The spleen indexes of the above groups were also significantly higher than in the ADM group(0.65 ± 0.22 vs 0.39 ± 0.17,P = 0.023;0.62 ± 0.34 vs 0.39 ± 0.17,P = 0.022;0.67 ± 0.20 vs 0.39 ± 0.17,P = 0.012),and the thymus indexes of the ADM + APS(100 mg/kg) and ADM + APS(200 mg/kg) groups were significantly higher than in the ADM group(0.20 ± 0.06 vs 0.13 ± 0.04,P = 0.029;0.47 ± 0.12 vs 0.13 ± 0.04,P = 0.000).APS was found to exert a synergistic antitumor effect with ADM and to alleviate the decrease in the sizes of the spleen and thymus induced by AMD.The expression of interleukin-1α(IL-1α),IL-2,IL-6,and tumor necrosis factor-α(TNF-α) was significantly higher in the ADM + APS(50 mg/kg),ADM + APS(100 mg/kg) and ADM + APS(200 mg/kg) groups than in the ADM group;and IL-10 was significantly lower in the above groups than in the ADM group.APS could increase IL-1α,IL-2,IL-6,and TNF-α expression and decrease IL-10 levels.Compared with the ADM group,APS treatment at a dose of 50-200 mg/kg could downregulate MDR1 mRNA expression in a dose-dependent manner(0.48 ± 0.13 vs 4.26 ± 1.51,P = 0.000;0.36 ± 0.03 vs 4.26 ± 1.51,P = 0.000;0.21 ± 0.04 vs 4.26 ± 1.51,P = 0.000).The expression level of P-GP was significantly lower in the ADM + APS(200 mg/kg) group than in the ADM group(137.35 ± 9.20 mg/kg vs 282.19 ± 20.54 mg/kg,P = 0.023).CONCLUSION:APS exerts a synergistic anti-tumor effect with ADM in H22 tumor-bearing mice.This may be related to its ability to enhance the expression of IL1α,IL-2,IL-6,and TNF-α,decrease IL-10,and downregulate MDR1 mRNA and P-GP expression levels. 展开更多

In patients with an acute ST-segment elevation myocardial infarction, timely myocardial reperfusion using primary percutaneous coronary intervention is the most effective therapy for limiting myocardial infarct size, preserving left-ventricular systolic function and reducing the onset of heart failure. Within minutes after the restoration of blood flow, however, reperfusion itself results in additional damage, also known as myocardial ischemia-reperfusion injury. An improved understanding of the pathophysiological mechanisms underlying reperfusion injury has resulted in the identification ofseveral promising pharmacological(cyclosporin-A, exenatide, glucose-insulin-potassium, atrial natriuretic peptide, adenosine, abciximab, erythropoietin, metoprolol and melatonin) therapeutic strategies for reducing the severity of myocardial reperfusion injury. Many of these agents have shown promise in initial proofof-principle clinical studies. In this article, we review the pathophysiology underlying myocardial reperfusion injury and highlight the potential pharmacological interventions which could be used in the future to prevent reperfusion injury and improve clinical outcomes in patients with coronary heart disease. 展开更多

AIM: To identify the proportion, causes and the nature of drug-induced liver injury (DILI) in patients with no- tably elevated alanine aminotransferase (ALT). METHODS: All the inpatients with ALT levels above 10 times upper limit of normal range (ULN) were ret- rospectively identified from a computerized clinical laboratory database at our hospital covering a 12-mo period. Relevant clinical information was obtained from medical records. Alternative causes of ALT eleva- tions were examined for each patient, including bili- ary abnormality, viral hepatitis, hemodynamic injury, malignancy, DILI or undetermined and other causes. All suspected DILI cases were causality assessed usingthe Council for International Organizations of Medical Sciences scale, and only the cases classified as highly probable, probable, or possible were diagnosed as DILI. Comments related to the diagnosis of DILI in the medical record and in the discharge letter for each case were also examined to evaluate DILI detection by the treating doctors. RESULTS: A total of 129 cases with ALT 〉 i0 ULN were identified. Hemodynamic injury (n = 46, 35.7%), DILl (n = 25, 19.4%) and malignancy (n = 21, 16.3%) were the top three causes of liver injury. Peak ALT val- ues were lower in DILI patients than in patients with hemodynamic injury (14.5 5.6 ULN vs 32.5 :I: 30.7 ULN, P = 0.001). Among DILI patients, one (4%) case was classified as definite, 19 (76%) cases were clas- sified as probable and 5 (20%) as possible according to the ClOMS scale. A hepatocellular pattern was ob- served in 23 (92%) cases and mixed in 2 (8%). The extent of severity of liver injury was mild in 21 (84%) patients and moderate in 4 (16%). Before discharge, 10 (40%) patients were recovered and the other 15 (60%) were improved. The improved patients tended to have a higher peak ALT (808 + 348 U/L vs 623 + 118 U/L, P = 0.016) and shorter treatment duration before discharge (8 + 6 d vs 28 ~ 12 d, P = 0.008) compared with the recovered patients. Twenty-two drugs and 6 herbs were found associated with DILl. Antibacterials were the most common agents causing DILI in 8 (32%) cases, followed by glucocorticoids in 6 (24%) cases. Twenty-four (96%) cases received treatment of DILl with at least one adjunctive drug. Agents for treatment of DILI included anti-inflammatory drugs (e.g., glycyr- rhizinate), antioxidants (e.g., glutathione, ademetionine 1,4-butanedisulfonate and tiopronin), polyene phospha- tidyl choline and herbal extracts (e.g., protoporphyrin disodium and silymarin). Diagnosis of DILl was not mentioned in the discharge letter in 60% of the cases. Relative to prevalent cases and cases from wards of internal medicine, incident cases and cases from surgi- cal wards had a higher risk of missed diagnosis in dis- charge letter [odds ratio (OR) 32.7, 95%CI (2.8-374.1),CONCLUSION: DILI is mostly caused by use of anti- bacterials and glucocorticoids, and constitutes about one fifth of hospitalized patients with ALT 〉 10 ULN. DILI is underdiagnosed frequently. 展开更多

Intrahepatic cholangiocarcinoma (ICC) is a rare primary liver cancer with a global increasing trend in recent years. Symptoms tend to be vague and insidious in development, often are diagnosed at an advanced stage when only palliative approaches can be used with a median survival rate of months. Comparing with HCC, ICC tends to spread to lymph nodes early, and is rarely limited to the regional lymph nodes, with a frequent postoperative recurrence. Surgery is the only choice of curative therapy for ICC, but recently no consensus has been established for operation. Thus, more data from multiple centers and more cases are needed. Generally speaking, current adjunctive therapy cannot clearly improve survival. Further research is needed to find more effective radio- and chemotherapeutic regimens. 展开更多

Attention deficit hyperactivity disorder(ADHD) manifests by high levels of inattention, impulsiveness and hyperactivity. ADHD starts in childhood and results in impairments that continue into adulthood. While hyperactivity declines over time, inattention and executive function difficulties persist, leading to functional deficits. Adolescents and adults with ADHD have pervasive impairment in interpersonal and family relationships. They may develop addiction, delinquent behavior and comorbid psychiatric disorders. Despite advances in diagnosis and treatment, persistent residual symptoms are common, highlighting the need for novel treatment strategies. Mindfulness training, derived from Eastern meditation practices, may improve self-regulation of attention. It may also be a useful strategy to augment standard ADHD treatments and may be used as a potential tool to reduce impairments in patients with residual symptoms of ADHD. Clinically, this would manifest by an increased ability to suppress task-unrelated thoughts and distractions resulting in improved attention, completion of tasks and potential improvement in occupational and social function. 展开更多
