文摘This paper investigates the optimization of data sampling and target labeling techniques to enhance algorithmic trading strategies in cryptocurrency markets,focusing on Bitcoin(BTC)and Ethereum(ETH).Traditional data sampling methods,such as time bars,often fail to capture the nuances of the continuously active and highly volatile cryptocurrency market and force traders to wait for arbitrary points in time.To address this,we propose an alternative approach using information-driven sampling methods,including the CUSUM filter,range bars,volume bars,and dollar bars,and evaluate their performance using tick-level data from January 2018 to June 2023.Additionally,we introduce the Triple Barrier method for target labeling,which offers a solution tailored for algorithmic trading as opposed to the widely used next-bar prediction.We empirically assess the effectiveness of these data sampling and labeling methods to craft profitable trading strategies.The results demonstrate that the innovative combination of CUSUM-filtered data with Triple Barrier labeling outperforms traditional time bars and next-bar prediction,achieving consistently positive trading performance even after accounting for transaction costs.Moreover,our system enables making trading decisions at any point in time on the basis of market conditions,providing an advantage over traditional methods that rely on fixed time intervals.Furthermore,the paper contributes to the ongoing debate on the applicability of Transformer models to time series classification in the context of algorithmic trading by evaluating various Transformer architectures—including the vanilla Transformer encoder,FEDformer,and Autoformer—alongside other deep learning architectures and classical machine learning models,revealing insights into their relative performance.

文摘Triple-negative breast cancer(TNBC)represents an aggressive breast cancer subtype with poor prognosis and limited targeted treatment options.This investigation examined the anticancer potential of Caerulomycin A(Cae A),a natural compound derived from marine actinomycetes,against TNBC.Cae A demonstrated selective inhibition of viability and proliferation in TNBC cell lines,including 4T1,MDA-MB-231,and MDA-MB-468,through apoptosis induction.Mechanistic analyses revealed that the compound induced sustained endoplasmic reticulum(ER)stress and subsequent upregulation of C/EBP homologous protein(CHOP)expression,resulting in mitochondrial damage-mediated apoptosis.Inhibition of ER stress or CHOP expression knockdown reversed mitochondrial damage and apoptosis,highlighting the essential role of ER stress and CHOP in Cae A's anti-tumor mechanism.Both oxygen consumption rate(OCR)and extracellular acidification rate(ECAR)decreased in TNBC cells following Cae A treatment,indicating reduced mitochondrial respiratory and glycolytic capacities.This diminished energy metabolism potentially triggers ER stress and subsequent apoptosis.Furthermore,Cae A exhibited significant anti-tumor effects in the 4T1 tumor model in vivo without apparent toxicity.The compound also effectively inhibited human TNBC organoid growth.These results indicate that Cae A may serve as a potential therapeutic agent for TNBC,with its efficacy likely mediated through the disruption of glucose metabolism and the induction of ER stress-associated apoptosis.
文摘BACKGROUND Patients with gastric cancer may have a risk of depression after radical surgery,which affects recovery and requires intensive intervention.AIM To explore the role of Bifidobacterium triple viable bacteria-assisted mirtazapine in patients with depression after radical surgery for gastric cancer.METHODS This study included 80 patients with gastric cancer who experienced depression after undergoing radical surgery from January 2022 to December 2023 at Jiangnan University Hospital in Wuxi city in Jiangsu province.The patients were categorized into the control group(n=40)treated with mirtazapine and observation group(n=40)treated with combined Bifidobacterium triple viable bacteria-assisted mirtazapine.Neuroendocrine index,intestinal flora level,nutrition status,and patient quality of life were analyzed.RESULTS Before drug index level,no statistically significant difference was observed between the two groups (P>0.05).After drug administration,both groups experienced a decline in depression scores,cortisol,Escherichia coli,Enterococcus faecalis levels,and quality of life scores,whereas dopamine,serotonin,Lactobacillus,Bifidobacteria,hemoglobin,serum albumin and prealbumin levels increased.The observation group demonstrated significantly greater improvements across these indicators,with significant differences within groups and between groups(P<0.05).CONCLUSION Bifidobacterium has a relieving effect on depression in patients after radical surgery for gastric cancer,improves neuroendocrine status,regulates intestinal flora,and improves nutritional status and quality of life.

文摘The global burden of Helicobacter pylori infection continues to drive the need for effective,well-tolerated,and regionally adaptable eradication regimens.Recently Han et al presented compelling results from a multicenter randomized controlled trial in China,demonstrating the non-inferiority and potential superiority of vonoprazan(VPZ)-based triple therapy over the standard 14-day bismuth quad-ruple regimen.Both the 10-day and 14-day VPZ-amoxicillin-clarithromycin regi-mens achieved eradication rates exceeding 90%per protocol,with similar or fewer adverse events,suggesting improved patient tolerability.This study reinforces the potential of VPZ to overcome the limitations of proton pump inhibitor-based regimens,particularly in populations with CYP2C19 polymorphisms and increa-sing clarithromycin resistance.These findings also lend support to shortened trea-tment durations,which could enhance adherence and reduce antimicrobial expo-sure.These data highlight an important shift in the therapeutic landscape,positio-ning VPZ as a strong candidate for first-line empirical therapies.However,broa-der implementation requires careful consideration of local resistance patterns,drug accessibility,and pharmacoeconomic implications.

文摘Accurately forecasting the triple point(TP)path is essential for analyzing blast loads and assessing the destructive effectiveness of the height of burst explosion.Empirical models that describe the TP path under normal temperature and pressure environments are commonly employed;however,in certain configurations,such as at high-altitudes(HAs),the environment may involve low temperature and pressure conditions.The present study develops a theoretical prediction model for the TP path under reduced pressure and temperature conditions,utilizing the image bursts method,reflected polar analysis,and dimensional analysis.The model's accuracy is evaluated through numerical simulations and experimental data.Results indicate that the prediction model effectively evaluates the TP path under diminished temperature and pressure conditions,with most predictions falling within a±15%deviation.It was found that the TP height increases with altitude.As the altitude rises from 0 m to 10,000 m,the average TP height increases by 61.7%,87.9%,109.0%,and 134.3%for the scaled height of burst of 1.5 m,2.0 m,2.5 m,and 3.0 m,respectively.Moreover,the variation in TP height under HA environments closely mirrors that observed under corresponding reduced pressure conditions.In HA environments,only the effect of low-pressure conditions on the TP path needs to be considered,as the environmental lowtemperature has a minimal effect.
文摘Dear Editor,We report a relatively safe and effective triple procedure for traumatic aphakia,glaucoma,and mydriasis.Blunt eye trauma can lead to various anterior-and posterior-segment conditions[1],that often occur simultaneously.Closed-globe injuries can damage one or more ocular structures.
文摘This article discusses the original article published by Lu et al in the latest issue.The article confirmed through a cohort study the clinical efficacy of the triple live bacteria of Bifidobacterium combined with mirtazapine in treating postoperative depression of gastric cancer patients,also explored the multi-target therapeutic mechanisms of Bifidobacterium triple viable bacteria combined with mirtazapine in managing depression in patients after radical gastrectomy for gastric cancer for the first time.The results indicated that Bifidobacterium could alleviate depression in patients after radical gastrectomy for gastric cancer.Gastric cancer patients undergoing surgery frequently experience postoperative psychological disorders,notably depression.These conditions not only impair quality of life but also negatively impact disease-free and overall survival.This editorial explores the underestimated psychological challenges following gastric cancer surgery,including depression,anxiety,adjustment disorders,and post-traumatic stress disorder.It further examines the therapeutic potential of Bifidobacterium triple viable probiotics,combined with mirtazapine,in alleviating postoperative depression through microbiological,immunological,and neurological mechanisms.Clinical evidence highlights additional benefits,such as improved gastrointestinal function,enhanced immunity,and better nutritional status,underscoring a holistic approach to postoperative care.While promising,further large-scale trials are needed to optimize and personalize probiotic-based interventions.
文摘BACKGROUND Breast cancer is a leading cause of cancer-related mortality among women worldwide,with invasive ductal carcinoma(IDC)being the most prevalent subtype.Lymph node metastasis is the primary prognostic indicator,typically evaluated via biopsy of the ipsilateral sentinel or axillary lymph nodes.Contralateral axillary metastasis(CAM)without ipsilateral involvement is exceedingly rare,particularly in early-stage breast cancer.This report presents a case of CAM in a patient with triple-negative breast cancer(TNBC),underscoring diagnostic and therapeutic complexities.CASE SUMMARY A 73-year-old female presented with left-sided early-stage IDC in February 2023.Despite a modified radical mastectomy and pathologically negative ipsilateral lymph nodes,a postoperative positron emission tomography(PET)scan detected fluorodeoxyglucose-avid nodes in the contralateral axilla.Biopsy confirmed metastatic ductal carcinoma with triple-negative status,resulting in an upstaged diagnosis of metastatic breast cancer,stage IV,M1.The patient underwent six cycles of adjuvant chemotherapy,with follow-up PET imaging showing regression of the contralateral lesion.This case highlights the importance of advanced imaging in TNBC for precise staging and treatment optimization.CONCLUSION This case highlights the aggressive nature of TNBC and the need for advanced imaging to ensure accurate staging and effective management.

文摘Triple negative breast cancer(TNBC)is an exceptionally aggressive subtype of breast cancer with a poor prognosis.TNBC patients have limited treatment options beyond conventional chemotherapy,and they face significant challenges associated with disease recurrence and resistance to chemotherapy.The phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)/mechanistic target of rapamycin(mTOR)signaling pathway plays a pivotal role in cell proliferation,growth,metabolism,and survival.Its aberrant activation is closely linked to the development and progression of TNBC,as well as treatment response and drug resistance.Currently,numerous targeted drugs specifically inhibiting this signaling pathway are being developed and undergoing clinical trials.These include inhibitors targeting PI3K,AKT,or mTOR individually,as well as dual-target or multi-target inhibitors simultaneously targeting different components of this pathway.Encouragingly,some inhibitors have demonstrated promising potential in clinical trials.This review delves into the therapeutic potential of the PI3K/AKT/mTOR signaling pathway for TNBC and explores prospects for drug discovery.
文摘BACKGROUND Standard triple therapy is an effective treatment for eradicating Helicobacter pylori infection,but it is encountered with drug resistance.The stool antigen test is a cost-effective and easy-to-perform test to confirm the eradication of H.pylori,4-8 weeks post-therapy,with 86%sensitivity and 92%specificity.AIM To assess the H.pylori eradication rate of standard triple therapy and factors affecting the eradication rate.METHODS We conducted a prospective,multicenter follow-up study in Addis Ababa,Ethiopia,at selected healthcare facilities among dyspeptic patients with positive stool H.pylori antigen tests from June 1,2023 to October 30,2023 to assess the H.pylori eradication rate.After completing the standard triple therapy,the eradication was confirmed using a stool antigen test 4 weeks later.The data were analyzed using bivariate and multivariate logistic regression methods.RESULTS The H.pylori eradication rate was 85.4%.Patients with a previous diagnosis of H.pylori infection,smokers,and local alcohol consumption were associated with a lower H.pylori eradication rate,with adjusted odds ratio(AORs)of 0.159[95%confidence interval(CI):0.050-0.511],0.206(95%CI:0.052-0.822),and 0.228(95%CI:0.052-0.997),respectively.Patients with complete symptom resolution were 5.383 times more likely to achieve eradication than patients without symptom improvement,AOR=5.383,95%CI:1.74-21.089.CONCLUSION H.pylori eradication rate was lower than expected.Post-treatment testing is crucial to confirm eradication and guide further management,such as susceptibility testing.
