BACKGROUND Although chronic erosive gastritis(CEG)is common,its clinical characteristics have not been fully elucidated.The lack of consensus regarding its treatment has resulted in varied treatment regimens.AIM To explore the clinical characteristics,treatment patterns,and short-term outcomes in CEG patients in China.METHODS We recruited patients with chronic non-atrophic or mild-to-moderate atrophic gastritis with erosion based on endoscopy and pathology.Patients and treating physicians completed a questionnaire regarding history,endoscopic findings,and treatment plans as well as a follow-up questionnaire to investigate changes in symptoms after 4 wk of treatment.RESULTS Three thousand five hundred sixty-three patients from 42 centers across 24 cities in China were included.Epigastric pain(68.0%),abdominal distension(62.6%),and postprandial fullness(47.5%)were the most common presenting symptoms.Gastritis was classified as chronic non-atrophic in 69.9%of patients.Among those with erosive lesions,72.1%of patients had lesions in the antrum,51.0%had multiple lesions,and 67.3%had superficial flat lesions.In patients with epigastric pain,the combination of a mucosal protective agent(MPA)and proton pump inhibitor was more effective.For those with postprandial fullness,acid regurgitation,early satiety,or nausea,a MPA appeared more promising.CONCLUSION CEG is a multifactorial disease which is common in Asian patients and has non-specific symptoms.Gastroscopy may play a major role in its detection and diagnosis.Treatment should be individualized based on symptom profile. 展开更多

BACKGROUND Real-world data on tofacitinib(TOF)covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis(UC)are scarce.AIM To investigate the long-term efficacy and safety of TOF treatment for UC,including clinical issues.METHODS We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center.All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled.Patients were followed up until August 2020.The primary outcome was the clinical response rate at week 8.Secondary outcomes included clinical remission at week 8,cumulative persistence rate of TOF administration,colectomy-free survival,relapse after tapering of TOF and predictors of clinical response at week 8 and week 48.RESULTS The clinical response and remission rates were 66.3%and 50.5%at week 8,and 47.1%and 43.5%at week 48,respectively.The overall cumulative clinical remission rate was 61.7%at week 48 and history of anti-tumor necrosis factor-alpha(TNF-α)agents use had no influence(P=0.25).The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8(30.9%vs 88.1%;P<0.001).Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8(odds ratio:0.61,95%confidence interval:0.45-0.82,P=0.001).Relapse occurred in 45.7%of patients after TOF tapering,and 85.7%of patients responded within 4 wk after re-increase.All 6 patients with herpes zoster(HZ)developed the infection after achieving remission by TOF.CONCLUSION TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-αagents.Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF.Special attention is needed for tapering and HZ. 展开更多

Purpose:Many science,technology and innovation(STI)resources are attached with several different labels.To assign automatically the resulting labels to an interested instance,many approaches with good performance on the benchmark datasets have been proposed for multi-label classification task in the literature.Furthermore,several open-source tools implementing these approaches have also been developed.However,the characteristics of real-world multi-label patent and publication datasets are not completely in line with those of benchmark ones.Therefore,the main purpose of this paper is to evaluate comprehensively seven multi-label classification methods on real-world datasets.Research limitations:Three real-world datasets differ in the following aspects:statement,data quality,and purposes.Additionally,open-source tools designed for multi-label classification also have intrinsic differences in their approaches for data processing and feature selection,which in turn impacts the performance of a multi-label classification approach.In the near future,we will enhance experimental precision and reinforce the validity of conclusions by employing more rigorous control over variables through introducing expanded parameter settings.Practical implications:The observed Macro F1 and Micro F1 scores on real-world datasets typically fall short of those achieved on benchmark datasets,underscoring the complexity of real-world multi-label classification tasks.Approaches leveraging deep learning techniques offer promising solutions by accommodating the hierarchical relationships and interdependencies among labels.With ongoing enhancements in deep learning algorithms and large-scale models,it is expected that the efficacy of multi-label classification tasks will be significantly improved,reaching a level of practical utility in the foreseeable future.Originality/value:(1)Seven multi-label classification methods are comprehensively compared on three real-world datasets.(2)The TextCNN and TextRCNN models perform better on small-scale datasets with more complex hierarchical structure of labels and more balanced document-label distribution.(3)The MLkNN method works better on the larger-scale dataset with more unbalanced document-label distribution. 展开更多

Battery pack capacity estimation under real-world operating conditions is important for battery performance optimization and health management,contributing to the reliability and longevity of batterypowered systems.However,complex operating conditions,coupling cell-to-cell inconsistency,and limited labeled data pose great challenges to accurate and robust battery pack capacity estimation.To address these issues,this paper proposes a hierarchical data-driven framework aimed at enhancing the training of machine learning models with fewer labeled data.Unlike traditional data-driven methods that lack interpretability,the hierarchical data-driven framework unveils the“mechanism”of the black box inside the data-driven framework by splitting the final estimation target into cell-level and pack-level intermediate targets.A generalized feature matrix is devised without requiring all cell voltages,significantly reducing the computational cost and memory resources.The generated intermediate target labels and the corresponding features are hierarchically employed to enhance the training of two machine learning models,effectively alleviating the difficulty of learning the relationship from all features due to fewer labeled data and addressing the dilemma of requiring extensive labeled data for accurate estimation.Using only 10%of degradation data,the proposed framework outperforms the state-of-the-art battery pack capacity estimation methods,achieving mean absolute percentage errors of 0.608%,0.601%,and 1.128%for three battery packs whose degradation load profiles represent real-world operating conditions.Its high accuracy,adaptability,and robustness indicate the potential in different application scenarios,which is promising for reducing laborious and expensive aging experiments at the pack level and facilitating the development of battery technology. 展开更多

Real-world engineering design problems with complex objective functions under some constraints are relatively difficult problems to solve.Such design problems are widely experienced in many engineering fields,such as industry,automotive,construction,machinery,and interdisciplinary research.However,there are established optimization techniques that have shown effectiveness in addressing these types of issues.This research paper gives a comparative study of the implementation of seventeen new metaheuristic methods in order to optimize twelve distinct engineering design issues.The algorithms used in the study are listed as:transient search optimization(TSO),equilibrium optimizer(EO),grey wolf optimizer(GWO),moth-flame optimization(MFO),whale optimization algorithm(WOA),slimemould algorithm(SMA),harris hawks optimization(HHO),chimp optimization algorithm(COA),coot optimization algorithm(COOT),multi-verse optimization(MVO),arithmetic optimization algorithm(AOA),aquila optimizer(AO),sine cosine algorithm(SCA),smell agent optimization(SAO),and seagull optimization algorithm(SOA),pelican optimization algorithm(POA),and coati optimization algorithm(CA).As far as we know,there is no comparative analysis of recent and popular methods against the concrete conditions of real-world engineering problems.Hence,a remarkable research guideline is presented in the study for researchersworking in the fields of engineering and artificial intelligence,especiallywhen applying the optimization methods that have emerged recently.Future research can rely on this work for a literature search on comparisons of metaheuristic optimization methods in real-world problems under similar conditions. 展开更多

Background: Localized pancreatic cancer, including resectable (R), borderline resectable (BR) and locally advanced unresectable disease (LAU), is considered in clinical guidelines for diverse treatment options based on clinical trials in selected populations. Hence, exploring with real world evidence (RWE) clinicians’ preferences for treatment options and their results seems pertinent. Methods: In a set of consecutive patients with localized pancreatic cancer assisted in a third level hospital from January 2013 to December 2022, medical records, symptoms, diagnostic process, distribution between subtypes, and treatment plans, with safety and efficacy results, were assessed. Results: A total of 152 patients with localized disease were included (43.4% R, 21.0% BR, 33.6% LAU). The population characteristics exemplified differences between daily practice and clinical trials. Tumor location and symptoms were as expected. Treatment plan was conditioned by PS or comorbidities in 23.0% of patients. In patients with R disease, surgery followed by different adjuvant chemotherapy (CT) regimes was the antineoplastic treatment of choice (64.8%) with efficacy results (OS 37.5 months;95% CI 18.4 - 56.7), in the range of contemporary standards. The common use of neoadjuvant CT for BR disease (94.4%), with surgery in 50% of them, and its results (OS 30.8 months;95% CI 10.5 - 51.2) reflected current controversies of treatment recommendations and evolution in this scenario. Paliative CT with or without radiotherapy was the standard specific treatment in LAU disease (95.1%) with survival results (PFS: 10.8 months;95% CI 8.8 - 12.7. OS: 20.3 months;95% CI 13.5 - 27.2) that justify the distinct character and the specific study of this entity. Conclusion: RWE for localized pancreatic cancer aroused from the analysis of this population confirms the distinct nature of patients assisted in daily practice, as well as mirrors the complexity of decision making in clinical assumptions in which achieving stronger evidence should be paramount. 展开更多

With the rapid development of modern science and technology, traditional randomized controlled trials have become insufficient to meet current scientific research needs, particularly in the field of clinical research. The emergence of real-world data studies, which align more closely with actual clinical evidence, has garnered significant attention in recent years. The following is a brief overview of the specific utilization of real-world data in drug development, which often involves large sample sizes and analyses covering a relatively diverse population without strict inclusion and exclusion criteria. Real-world data often reflects real clinical practice: treatment options are chosen according to the actual conditions and willingness of patients rather than through random assignment. Analysis based on real-world data also focuses on endpoints highly relevant to clinical benefits and the quality of life of patients. The booming big data technology supports the utilization of real-world data to accelerate new drug development, serving as an important supplement to traditional clinical trials. 展开更多

The literary background of Kazuo Ishiguro’s novel Never Let Me Go sets in a highly developed scientific and technological world where clones are created by human and“educated”in the Hailsham School for the sake of“donating”their vital organs to human three or four times before death.By depicting miserable fate of clones,the novel conveys deep concerns on the consequences of abusing technology in modern society.Ever since the burgeoning development of life science and artificial intelligence in the 1990s,the trend of posthumanism/transhumanism has emerged.Posthumanism promotes approaches to enhancing human body condition and organism,and extending human lifespan to augment human capacity and well-being by the advancement of technology.In literary field,contemplation on the relationship between human beings and technology has become a major concern of posthumanism.Putting Never Let Me Go in the context of posthumanism,this essay probes into the significant themes of the novel from three aspects:(1)clones’torments in the existential predicaments imposed by human;(2)human’s violation to the principles of bioethics causing the existential predicaments of alienated clones;(3)appealing to human to ruminate on the relationship between scientific technology and ethics. 展开更多

The security dilemma is a common problem faced with the states in the ongoing anarchic international system.It does matter in the Middle East like the other ones and also has its impact on the arms races in the region too.Meanwhile there are some characters named as the order and change predicaments such as the colonial background,weak infrastructure of state construction,and the identity politics embedded in the region that do convert the current complex security dilemma into a complicated one.Not only does it have effect on the regional order,the arm race and disarmament,and also offense/defense paradox,but also does it get on the violent bandwagon in the region.Synergies of the both dilemmas did lead the region into the domestic environment change alongside of regional disorder too.Non-neutral involving the trans-regional powers into the(in)security situation in the region not only did not mitigate the situation but also volatile it too.In conclusion the paper does strive to introduce three phrased manners for transition of the complicated security dilemma. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC) is a common malignant tumor worldwide. Many regions across the world have issued various HCC diagnosis and treatment protocols to improve the diagnosis and targeted treatment of patients with HCC. However, real-world studies analysing the practice, application value, and existing problems of the China Liver Cancer(CNLC) staging system are scarce.AIM To analyze the current situation and problems associated with the Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China.METHODS We collected the medical records of all patients with HCC admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2011 to December 31, 2019, and recorded the hospitalization information of those patients until December 31, 2020. All information on the diagnosis and treatment of the target patients was recorded, and their demographic and sociological characteristics, CNLC stages, screening situations, and treatment methods and effects were analyzed. The survival status of the patients was obtained from follow-up data.RESULTS This study included the medical records of 3022 patients with HCC. Among these cases, 304 patients were screened before HCC diagnosis;their early-stage diagnosis rate was 69.08%, which was significantly higher than that of patients with HCC who were diagnosed without screening and early detection(33.74%). Herein, patients with no clinical outcome at discharge were followed up, and the survival information of 1128 patients was obtained. A Cox model was used to analyse independent risk factors affecting overall survival, which were revealed as age > 50 years, no screening, alpha-fetoprotein > 400 ng/mL, Child–Pugh grade B, and middle and late CNLC stages. Based on the Cox model survival analysis, in our study, patients with HCC identified via screening had significant advantages in overall and tumorfree survival after hepatectomy.CONCLUSION Early diagnosis and treatment can be achieved by screening groups at high risk for HCC based on the guidelines;however, real-world compliance is poor. 展开更多

Object:The aim is to evaluate how effective Traditional Chinese Medicine(TCM)is in treating patients who have central retinal vein occlusion with macular edema(CRVO-ME)in a real-world study.Furthermore,the objective of the research was to examine the TCM prescription trends in the management of CRVO-ME.Method:A single-center real-world study(RWS)was carried out over a span of 19 years,following the established design.The study encompassed 113 patients diagnosed with CRVO-ME.Out of these,74 patients received TCM treatment,while the remaining individuals underwent a combined therapy involving TCM and anti-VEGF drugs through intravitreal injection.The patients were matched using propensity score matching(PSM).The result measured in the RWS was BCVA.The oral prescriptions for CRVO-ME that led to observable and effective outcomes were collected.Excel and the TCM Inheritance Auxiliary Platform V2.5 were utilized to optimize mutual information,hierarchical clustering based on entropy,and other techniques to extract medication regulations and features.Result:After applying PSM,each group comprised 29 cases.Both groups exhibited improved BCVA following treatment;however,there was no statistically significant distinction in BCVA or effectiveness between the two groups(all P>0.05).Apart from the analysis of oral prescriptions for CRVO-ME,the investigation pinpointed the most frequently used TCMs,namely Flos Carthami,Semen Persicae,Radix Angelica sinensis,Radix Rehmanniae,and Radix et Rhizoma Notoginseng.Frequently utilized medications tended to possess cold,warm,or mild attributes and exhibited a taste profile that was either bitter or sweet.The primary meridians associated with the medicines employed in treating CRVO-ME were liver,spleen,stomach,heart,and lung.Through the application of association rule analysis,it was discerned that there were 195 commonly employed combinations of medicines.Additionally,a complex system entropy cluster analysis unveiled 13 key combinations of medicines.By employing an unsupervised entropy hierarchical clustering analysis,a novel prescription was formulated.Conclusion:Within a real-world population of CRVO-ME patients,TCM exhibited its effectiveness.The treatment approach for CRVO-ME predominantly involved the regulation of qi(Qi is an exceedingly subtle substance within the human body,brimming with vitality and ceaseless motion.It constitutes the fundamental element that shapes and sustains the various processes of human life.)and blood as well as the resolution of dampness.The oral prescriptions frequently targeted the meridians of liver,spleen,stomach,heart,and lungs. 展开更多
