[Method] Sixty weaned piglets, 25 days old, were randomly divided into two groups, six replicates each group, and each replicate contained five piglets. Piglets in control group were fed with the conversation feed developed by traditional granulating process, and those in experimental group were fed with the conservation feed developed by post-expanding lower temperature granulating process. The trial lasted 28 d. [Result] Compared to traditional granulating process, post-expanding lower temperature granulating process significantly enhanced starch gelatinization degree of conservation feed by56.9%（P〈0.05）, and significantly improved in vitro protein digestibility of conservation feed by 11.48%（P〈0.05）. Compared to the control group, the feed intake of piglets in experimental group was increased by 21.63%（P〈0.05）; the average daily gain was increased by 27.61%（P〈0.05）; the diarrhea rate was lowered; and the feed gain ratio was improved by 4.51%（P〉0.05）. The results suggested that post-expanding lower temperature granulating process effectively enhanced feed digestion and absorption of piglets. [Conclusion] The paper provides a theoretical basis and practical reference for improvement of production process of conservation feed.展开更多

However, there is currently no evidence to prove which treatment method is most effective. Traditional Chinese Medicine(TCM) has shown certain advantages in the treatment of PLC, especially in the side effects of Western Medicine. Therefore, we designed a clinical trial protocol for the treatment of PLC using TCM granules. Our purpose is to explore the efficacy and safety of Yangxiao Fukang granule(YXFKG, 养消复康颗粒) in the treatment of stage Ⅲ hepatitis B related PLC. A total of 216 patients from three hospitals in Henan Province will be enrolled and randomly divided into a trial group and a control group in a 1 ∶ 1 ratio. The trial group will be treated with conventional western medicine plus YXFKG, while the control group will receive conventional western medicine plus a placebo for YXFKG. All patients will receive a daily dose of either YXFKG or a placebo for six months, followed by a six-month follow-up period. The main observation outcome includes 1-year survival rate, while secondary outcomes include conversion rate to remission, objective response rate, progression free survival, overall survival, quality of life score, and TCM clinical symptom score. Blood routine, urine routine, stool routine, electrocardiogram, liver and kidney function, coagulation function test, and D-dimer are safety indicators. Collect data before treatment and during the 3rd, 6th, 9th, and 12th months of treatment, and conduct statistical analysis. This study will preliminarily verify the effectiveness and safety of YXFKG in the treatment of stage Ⅲ hepatitis B related PLC, which may provide a new choice for clinical treatment of PLC.展开更多

文摘Decision implication is a form of decision knowledge represen-tation,which is able to avoid generating attribute implications that occur between condition attributes and between decision attributes.Compared with other forms of decision knowledge representation,decision implication has a stronger knowledge representation capability.Attribute granularization may facilitate the knowledge extraction of different attribute granularity layers and thus is of application significance.Decision implication canonical basis(DICB)is the most compact set of decision implications,which can efficiently represent all knowledge in the decision context.In order to mine all deci-sion information on decision context under attribute granulating,this paper proposes an updated method of DICB.To this end,the paper reduces the update of DICB to the updates of decision premises after deleting an attribute and after adding granulation attributes of some attributes.Based on this,the paper analyzes the changes of decision premises,examines the properties of decision premises,designs an algorithm for incrementally generating DICB,and verifies its effectiveness through experiments.In real life,by using the updated algorithm of DICB,users may obtain all decision knowledge on decision context after attribute granularization.

文摘Characteristic of iron ore is the essential factor of granulating.Three ores,namely specularite,magnetite concentrate and limonite,were selected as adhesion powder to investigate granulating behavior and evolution process of agglomeration.Experiments and modeling were performed to represent granulating behavior on the basis of selectivity,ballability and adhesion rate.The mass fraction of water and particles size of adhesion and nucleation were set at(11±1)%,0-1 mm and 3-5 mm,respectively.Experimental results show that selectivity and ballability promote the evolution of granulation.The water absorption rate of specularite and the ballability of limonite are better.The coupling effects exist in two ores mixing and present positive effect when the proportion of magnetite concentrate is greater than that of specularite or specularite and limonite blend.During three ores mixing,the coupling effect presents a complex superposition state.A characterization model of adhesion rate of mixing granulation was established by random forest algorithms.Its output is adhesion rate,and its inputs include water absorption rate,balling index and mixing proportion.The model parameters are 957 trees and four branches,and the training and prediction errors of the model are 2.3%and 3.7%,respectively.Modeling indicates that the random forest model can be used to represent coupling effects of mixing granulation.

文摘[Objective] The paper was to compare the effects of traditional granulating process and post-expanding lower temperature granulating process on starch gelatinization degree and in vitro protein digestibility of conversation feed, and growth performance of piglets. [Method] Sixty weaned piglets, 25 days old, were randomly divided into two groups, six replicates each group, and each replicate contained five piglets. Piglets in control group were fed with the conversation feed developed by traditional granulating process, and those in experimental group were fed with the conservation feed developed by post-expanding lower temperature granulating process. The trial lasted 28 d. [Result] Compared to traditional granulating process, post-expanding lower temperature granulating process significantly enhanced starch gelatinization degree of conservation feed by56.9%（P〈0.05）, and significantly improved in vitro protein digestibility of conservation feed by 11.48%（P〈0.05）. Compared to the control group, the feed intake of piglets in experimental group was increased by 21.63%（P〈0.05）; the average daily gain was increased by 27.61%（P〈0.05）; the diarrhea rate was lowered; and the feed gain ratio was improved by 4.51%（P〉0.05）. The results suggested that post-expanding lower temperature granulating process effectively enhanced feed digestion and absorption of piglets. [Conclusion] The paper provides a theoretical basis and practical reference for improvement of production process of conservation feed.

文摘The dentate gyrus of the hippocampus is a plastic structure that displays modifications at different levels in response to positive stimuli as well as to negative conditions such as brain damage.The latter involves global alterations,making understanding plastic responses triggered by local damage difficult.One key feature of the dentate gyrus is that it contains a well-defined neurogenic niche,the subgranular zone,and beyond neurogenesis,newly born granule cells may maintain a“young”phenotype throughout life,adding to the plastic nature of the structure.Here,we present a novel experimental model of local brain damage in organotypic entorhino-hippocampal cultures that results in the activation of adjacent newly born granule cells.A small piece of filter paper was placed on the surface of the granule cell layer of the dentate gyrus,which evoked a foreign body reaction of astrocytes,along with the activation of local young neurons expressing doublecortin.Forty-eight hours after foreign body placement,the number of doublecortin-immunoreactive cells increased in the subgranular zone in the direct vicinity of the foreign body,whereas overall increased doublecortin immunoreactivity was observed in the granule cell layer and molecular layer of the dentate gyrus.Foreign body placement in the pyramidal layer of the CA1 region evoked a comparable local astroglial reaction but did not lead to an increase in doublecortin-immunoreactive in either the CA1 region or the adjacent dentate gyrus.Seven days after foreign body placement in the dentate gyrus,the increase in doublecortin-immunoreactivity was no longer observed,indicating the transient activation of young cells.However,7 days after foreign body placement,the number of doublecortin-immunoreactive granule cells coimmunoreactive for calbindin was lower than that under the control conditions.As calbindin is a marker for mature granule cells,this result suggests that activated young cells remain at a more immature stage following foreign body placement.Live imaging of retrovirally green fluorescent protein-labeled newly born granule cells revealed the orientation and growth of their dendrites toward the foreign body placement.This novel experimental model of foreign body placement in organotypic entorhino-hippocampal cultures could serve as a valuable tool for studying both glial reactivity and neuronal plasticity,specifically of newly born neurons under controlled in vitro conditions.

文摘Stress granules are membraneless organelles that serve as a protective cellular response to external stressors by sequestering non-translating messenger RNAs(mRNAs)and regulating protein synthesis.Stress granules formation mechanism is conserved across species,from yeast to mammals,and they play a critical role in minimizing cellular damage during stress.Composed of heterogeneous ribonucleoprotein complexes,stress granules are enriched not only in mRNAs but also in noncoding RNAs and various proteins,including translation initiation factors and RNA-binding proteins.Genetic mutations affecting stress granule assembly and disassembly can lead to abnormal stress granule accumulation,contributing to the progression of several diseases.Recent research indicates that stress granule dynamics are pivotal in determining their physiological and pathological functions,with acute stress granule formation offering protection and chronic stress granule accumulation being detrimental.This review focuses on the multifaceted roles of stress granules under diverse physiological conditions,such as regulation of mRNA transport,mRNA translation,apoptosis,germ cell development,phase separation processes that govern stress granule formation,and their emerging implications in pathophysiological scenarios,such as viral infections,cancer,neurodevelopmental disorders,neurodegeneration,and neuronal trauma.

文摘Pinelliae Rhizoma(PR),known as Banxia in Chinese,Hange in Japanese,and Banha in Korean,is a renowned herbal medicine in East Asia derived from the dry tuber of Pinellia ternata(Thunb.)Breit.(PT).It is extensively utilized in dispensing granules,classical prescriptions,and herbal formulas to treat various conditions,including cough,infection,phlegm,nausea,asthma,and inflammation.Despite numerous studies on PR and its classical prescriptions over recent decades,a comprehensive synthesis of available evidence regarding its multifunctional roles and therapeutic potential is lacking.This review aims to address this gap by examining emerging evidence from metabonomics,preclinical studies,and clinical trials,while exploring potential trends and prospects for future research.A systematic literature search was conducted across six electronic databases,including Pub Med,Web of Science,Scopus,Science Direct,Wanfang,and China National Knowledge Infrastructure,to identify relevant articles on PR published until March 2023.PR contains 107 compounds with diverse pharmacological activities,including anti-inflammatory,immune regulatory,anti-viral,anti-cancer,anti-asthma,antitussive and expectorant,antioxidant,anti-obesity,anti-atherosclerosis,antimicrobial,emetic and anti-emetic,anti-convulsant and anti-epileptic,sedative and hypnotic,learning and memory enhancement,and anti-depressant effects.Metabonomic studies suggest that raw PR may exhibit cardiotoxicity and pregnancy toxicity while showing no apparent hepatorenal toxicity.However,limited pharmacokinetic investigations on PR constrain its clinical translation.Furthermore,clinical safety data on PR is scarce,with only four clinical trials assessing its positive effects in pediatric epilepsy,nausea and vomiting,soft tissue injury,and chronic sinus tract.This review aims to enhance understanding of PR and provide valuable information and recommendations for further research and development of herbal medicine.

文摘Leachate sludge,a byproduct of municipal solid waste leachate treated through biochemical processes,is characterized by high water content(761.1%)and significant organic matter content(71.2%).Cement that is commonly used for solidifying leachate sludge has shown limited effectiveness.To address this issue,an alkali-activated ground-granulated blast-furnace slag(GGBS)geopolymer blended with polypropylene fibers was developed to solidify leachate sludge.Moreover,unconfined compressive strength(UCS),immersion,as well as X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),and scanning electron microscope(SEM)tests were conducted to investigate the solidification effect and mechanism of the GGBS-based geopolymer and fibers on leachate sludge.The results showed that:the 28-d UCS of the solidified sludge with 20%and 30%GGBS is 0.35 MPa and 1.85 MPa,and decreases to 0.18 MPa and 1.13 MPa,respectively,after soaked in water for 28 d.Notably,the UCS of the solidified sludge with 30%GGBS satisfied the strength requirement of roadbed materials.Polypropylene fibers significantly enhanced the strength,ductility and water stability of the solidified sludge,with an optimal fiber content of 0.3%.Alkali-activated GGBS geopolymer generated three-dimensional,cross-linked geopolymeric gels within the solidified sludge,cementing sludge particles and filling intergranular pores to form a stable cementitious structure,thereby achieving effective solidification.Furthermore,incorporating polypropylene fibers improved the bonding and anchoring effect between fiber and solidified sludge,constrained lateral deformation of the solidified sludge,restricted crack propagation,and enhanced engineering performance of the solidified leachate sludge.

文摘OBJECTIVE:To explore if Hewei Jiangni granule(和胃降逆颗粒,HWJNG)could regulate esophageal hypersensitivity via stromal interaction molecule 1(STIM1)/transient receptor potential vanilloid subfamily member 1(TRPV1)pathway.METHODS:Qualitative analysis of HWJNG was analysis by high performance of liquid and gas chromatography.In vivo,animal model of non-erosive reflux disease(NERD)was established by fructose intake and restraint stress.HWJNG and Omeprazole were administered by gavage to the drug intervention group.Reflux and visceral hypersensitivity were analyzed by pathological changes,PH value test,mechanical paw withdrawal threshold,thermal withdrawal latency and mast cells(MCs)degranulation.In vitro,substance P(SP)-induced P815 cells and dorsal root ganglion(DRG)cells were cocultured.Expression in both mice and cells of STIM1,TRPV1,and esophageal visceral hypersensitivity-related gastrointestinal neurochemicals were validated by enzyme linked immunosorbent assays,quantitative realtime polymerase chain reaction(qRT-PCR)and Western blot.Moreover,overexpression and small interfering RNA against STIM1 were utilized to verify of the role of HWJNG in DRG cells.RESULTS:HWJNG significantly suppressed intercellular space widening,injury of mitochondrial,MCs degranulation,mechanical allodynia and heat neuropathic sensory and increased pH value of esophageal mucosa in NERD mice.HWJNG inhibited expression of visceral hypersensitivityrelated gastrointestinal neurochemicals in esophageal mucosa and activated P815 cells,and expression of the STIM1,TRPV1 and related neurotransmitters in DRG and DRG cells.STIM1 siRNA and HWJNG both reduced P815 cells adhesion to DRGs cells and Ca2+flow into the cytoplasmic space of DRG cells.Furthermore,HWJNG could reversed STIM1 overexpression induced upregulation of TRPV1.CONCLUSION:HWJNG suppressed intercellular space widening in NERD mice,stabilized MCs and restored neuronal hyperexcitability by regulating visceral hypersensitivity via STIM1/TRPV1 pathway.
文摘BACKGROUND Owing to the absence of specific symptoms in early-stage gastric cancer,most patients are diagnosed at intermediate or advanced stages.As a result,treatment often shifts from surgery to other therapies,with chemotherapy and targeted therapies being the primary options for advanced gastric cancer treatment.A total of 116 patients with advanced gastric cancer,admitted from January 2021 to December 2023,were selected and divided into two groups of 58 each using the random number table method.The control group received FOLFOX4 chemothe-rapy(oxaliplatin+calcium+folinate+5-fluorouracil)combined with intravenous sindilizumab.The observation group received the same treatment as the control group,supplemented by oral administration of Senqi Shiyiwei granules.Both groups underwent treatment cycles of 3 weeks,with a minimum of two cycles.The therapeutic efficacy,immune mechanisms,and treatment-related toxicity and side effects were compared between the groups.The objective remission rate in the observation group(55.17%)was higher than that of the control group(36.21%)(P<0.05).After two treatment cycle,CD3+,CD4+,and CD4+/CD8+levels were higher in the observation group compared to the control group,while CD8+,regulatory T cells,and natural killer cells were lower(P<0.05).Additionally,the incidence of leukopenia,nausea,and vomiting was lower in observed group(P<0.05).No significant differences were observed in the incidence of other adverse reactions(P>0.05).CONCLUSION Adjuvant therapy with Shenqixian granules may enhance the efficacy of simudizumab combined with FOLFOX4 chemotherapy in advanced gastric cancer and the immune function by increasing immune cell counts,making it a valuable option in clinical treatment.

文摘Osteosarcoma(OS)is the most frequent primary bone sarcomas with high recurrence and poor prognosis.Emerging evidence indicates that membraneless organelles stress granules(SGs),whose assemblies are driven by scaffold protein G3BP1,are extensively involved in tumor,especially in OS.However,how SGs behave and communicate with organelles,particularly nucleoli and mitochondria,during drug challenges remain unknown.This study revealed that chemotherapeutic drugs activated the cysteine protease asparagine endopeptidase(AEP)to specifically cleave the SG core protein G3BP1 at N258/N309 in OS and malignant glioma.tG3BP1-Ns modulated SG dynamics by competitively binding to full-length G3BP1.Strikingly,tG3BP1-Cs,containing a conserved RNA recognition motif CCUBSCUS,sequestered mRNAs of ribosomal proteins and oxidative phosphorylation genes in the nucleoli and mitochondria to repress translation and oxidative stress.Moreover,the inhibition of AEP promoted the tumor-suppressing effect of chemotherapeutic drugs,whereas AEP-cleaved G3BP1 rescue reversed the effect in both OS and glioma models.Cancerous tissues exhibited high levels of AEP and G3BP1 truncations,which were strongly associated with poor prognosis.
文摘BACKGROUND Mesalamine is the recommended first-line treatment for inducing and maintaining remission in mild-to-moderate ulcerative colitis(UC).However,adherence in real-world settings is frequently suboptimal.Encouraging collaborative patient-provider relationships may foster better adherence and patient outcomes.AIM To quantify the association between patient participation in treatment decisionmaking and adherence to oral mesalamine in UC.METHODS We conducted a 12-month,prospective,non-interventional cohort study at 113 gastroenterology practices in Germany.Eligible patients were aged≥18 years,had a confirmed UC diagnosis,had no prior mesalamine treatment,and provided informed consent.At the first visit,we collected data on demographics,clinical characteristics,patient preference for mesalamine formulation(tablets or granules),and disease knowledge.Self-reported adherence and disease activity were assessed at all visits.Correlation analyses and logistic regression were used to examine associations between adherence and various factors.RESULTS Of the 605 consecutively screened patients,520 were included in the study.The median age was 41 years(range:18-91),with a male-to-female ratio of 1.1:1.0.Approximately 75%of patients reported good adherence at each study visit.In correlation analyses,patient participation in treatment decision-making was significantly associated with better adherence across all visits(P=0.04).In the regression analysis at 12 months,this association was evident among patients who both preferred and received prolonged-release mesalamine granules(odds ratio=2.73,P=0.001).Patients reporting good adherence also experienced significant improvements in disease activity over 12 months(P<0.001).CONCLUSION Facilitating patient participation in treatment decisions and accommodating medication preferences may improve adherence to mesalamine.This may require additional effort but has the potential to improve long-term management of UC.

文摘Applying domain knowledge in fuzzy clustering algorithms continuously promotes the development of clustering technology.The combination of domain knowledge and fuzzy clustering algorithms has some problems,such as initialization sensitivity and information granule weight optimization.Therefore,we propose a weighted kernel fuzzy clustering algorithm based on a relative density view(RDVWKFC).Compared with the traditional density-based methods,RDVWKFC can capture the intrinsic structure of the data more accurately,thus improving the initial quality of the clustering.By introducing a Relative Density based Knowledge Extraction Method(RDKM)and adaptive weight optimization mechanism,we effectively solve the limitations of view initialization and information granule weight optimization.RDKM can accurately identify high-density regions and optimize the initialization process.The adaptive weight mechanism can reduce noise and outliers’interference in the initial cluster centre selection by dynamically allocating weights.Experimental results on 14 benchmark datasets show that the proposed algorithm is superior to the existing algorithms in terms of clustering accuracy,stability,and convergence speed.It shows adaptability and robustness,especially when dealing with different data distributions and noise interference.Moreover,RDVWKFC can also show significant advantages when dealing with data with complex structures and high-dimensional features.These advancements provide versatile tools for real-world applications such as bioinformatics,image segmentation,and anomaly detection.

文摘Primary liver cancer(PLC) is the third major cause of cancer related death, which seriously affects the survival period and quality of life of patients. However, there is currently no evidence to prove which treatment method is most effective. Traditional Chinese Medicine(TCM) has shown certain advantages in the treatment of PLC, especially in the side effects of Western Medicine. Therefore, we designed a clinical trial protocol for the treatment of PLC using TCM granules. Our purpose is to explore the efficacy and safety of Yangxiao Fukang granule(YXFKG, 养消复康颗粒) in the treatment of stage Ⅲ hepatitis B related PLC. A total of 216 patients from three hospitals in Henan Province will be enrolled and randomly divided into a trial group and a control group in a 1 ∶ 1 ratio. The trial group will be treated with conventional western medicine plus YXFKG, while the control group will receive conventional western medicine plus a placebo for YXFKG. All patients will receive a daily dose of either YXFKG or a placebo for six months, followed by a six-month follow-up period. The main observation outcome includes 1-year survival rate, while secondary outcomes include conversion rate to remission, objective response rate, progression free survival, overall survival, quality of life score, and TCM clinical symptom score. Blood routine, urine routine, stool routine, electrocardiogram, liver and kidney function, coagulation function test, and D-dimer are safety indicators. Collect data before treatment and during the 3rd, 6th, 9th, and 12th months of treatment, and conduct statistical analysis.

文摘BACKGROUND Current disinfection methods for gastrointestinal endoscopes consume a significant amount of water resources and produce a large volume of waste.AIM To achieve the objectives of efficiency,speed,and cost-effectiveness,this study utilized vaporized hydrogen peroxide(VHP)generated from sodium percarbonate granules to conduct an anhydrous disinfection test on gastrointestinal endoscopes.METHODS The experimental device rapidly converts sodium percarbonate granules into VHP,and performs disinfection experiments on gastrointestinal endoscope models,disposable endoscopes,and various types of reusable gastrointestinal endoscopes.Variables such as the intraluminal flow rate(FR),relative humidity(RH),exposure dosage,and organic burden are used to explore the factors influencing the disinfection of long and narrow lumens with VHP.RESULTS The device generates a certain concentration of VHP that can achieve high-level disinfection of endoscope models within 30 minutes.RH,exposure dosage,and organic burden significantly affect the disinfection efficacy of VHP,whereas the intraluminal FR does not significantly impact disinfection efficacy.All ten artificially contaminated disposable endoscopes achieved satisfactory disinfection results.Furthermore,when this device was used to treat various types of reusable endoscopes,the disinfection and sterilization effects were not significantly different from those of automatic endoscope disinfection machines(using peracetic acid disinfectant solution)(P>0.05),and the economic cost of disinfectant required per endoscope was lower(1.5 China Yuan),with a shorter disinfection time(30 minutes).CONCLUSION The methods and results of this study provide a basis for further research on the use of VHP for the disinfection of gastrointestinal endoscopes,as well as for the development of anhydrous disinfection technology for gastrointestinal endoscopes.
