In the theoretical section, the model introduction and estimation algorithms are provided. In the empirical analysis section, global air quality data from 2022 to 2024 are used, and the proposed method is applied. Specifically, principal component analysis (PCA) is first conducted, and then VAR and Random Forest methods are used for prediction on the reduced-dimensional data. The results show that the RMSE of the hybrid model is 45.27, significantly lower than the 49.11 of the VAR model alone, verifying its superiority. The stability and predictive performance of the model are effectively enhanced.展开更多

The shallow gassy soils significantly affect the construction of underground projects. Proper characterization of spatial distribution of shallow gassy soils is indispensable prior to construction of underground projects in the area. Due to the costly conditions required in the site investigation for gassy soils, only a limited number of gas pressure data can be obtained in engineering practice, which leads to the uncertainty in characterizing spatial distribution of gassy soils. Determining the number of boreholes for investigating gassy soils and their corresponding locations is pivotal to reducing construction risk induced by gassy soils. However, this primarily relies on the engineering experience in the current site investigation practice. This study develops a probabilistic site investigation optimization method for planning investigation schemes (including the number and locations of boreholes) of gassy soils based on the conditional random field and Monte Carlo simulation. The proposed method aims to provide an optimal investigation scheme before the site investigation based on prior knowledge. Finally, the proposed approach is illustrated using a case study.展开更多

文摘The current study aimed to evaluate the efficacy and safety of Compound Danshen Dripping Pills(CDDP)in improving cardiac function in patients with acute anterior ST-segment elevation myocardial infarction(AAMI).Between February 2021 and February 2023,247 eligible patients with AAMI after primary percutaneous coronary intervention were enrolled and randomly assigned(1∶1)to receive CDDP(n=126)or placebo(n=121),with a follow-up of 48 weeks.Compared with the placebo group,the CDDP group demonstrated a significant increase in left ventricular ejection fraction values after 24 weeks of treatment(least squares mean:3.31;95%confidence interval[CI]:1.72–4.90;P<0.001)and at the 48-week follow-up(least squares mean:4.35;95%CI:2.76–5.94;P<0.001).Significant reductions in N-terminal pro-B-type natriuretic peptide levels were observed in both groups at the 24-and 48-week visits with no significant difference between the two groups(P>0.1 for all).The incidence of major adverse cardiovascular and cerebrovascular events was 6.35%in the CDDP group and 5.79%in the placebo group(P=0.822).Notably,no serious adverse events were attributed to CDDP.These findings suggest that CDDP may be well tolerated and could improve left ventricular ejection fraction in patients with AAMI at 24 and 48 weeks.

文摘To improve the efficiency of air quality analysis and the accuracy of predictions, this paper proposes a composite method based on Vector Autoregressive (VAR) and Random Forest (RF) models. In the theoretical section, the model introduction and estimation algorithms are provided. In the empirical analysis section, global air quality data from 2022 to 2024 are used, and the proposed method is applied. Specifically, principal component analysis (PCA) is first conducted, and then VAR and Random Forest methods are used for prediction on the reduced-dimensional data. The results show that the RMSE of the hybrid model is 45.27, significantly lower than the 49.11 of the VAR model alone, verifying its superiority. The stability and predictive performance of the model are effectively enhanced.
文摘Gassy soils are distributed in relatively shallow layers the Quaternary deposit in Hangzhou Bay area. The shallow gassy soils significantly affect the construction of underground projects. Proper characterization of spatial distribution of shallow gassy soils is indispensable prior to construction of underground projects in the area. Due to the costly conditions required in the site investigation for gassy soils, only a limited number of gas pressure data can be obtained in engineering practice, which leads to the uncertainty in characterizing spatial distribution of gassy soils. Determining the number of boreholes for investigating gassy soils and their corresponding locations is pivotal to reducing construction risk induced by gassy soils. However, this primarily relies on the engineering experience in the current site investigation practice. This study develops a probabilistic site investigation optimization method for planning investigation schemes (including the number and locations of boreholes) of gassy soils based on the conditional random field and Monte Carlo simulation. The proposed method aims to provide an optimal investigation scheme before the site investigation based on prior knowledge. Finally, the proposed approach is illustrated using a case study.

文摘OBJECTIVE:In recent years,the number of clinical research reports on acupuncture and manipulation for the treatment of greater occipital neuralgia has gradually increased,but the quality is uneven.There is currently no literature evaluating the quality of published reports,which is not conducive to the promotion of clinical use of these therapies.Therefore,this article assessed the reporting quality of randomized controlled trials on acupuncture and manipulation for greater occipital neuralgia.METHODS:Cochrane Library,PubMed,Web of Science,Embase,China National Knowledge Infrastructure(CNKI),VIP,WanFang Data,and Chinese BioMedical Literature Database(CBM)from inception to May 20,2024 were searched.The reporting quality of included randomized controlled trials was independently evaluated by two investigators using the CONSORT statement,STRICTA checklist,and Cochrane bias of risk assessment tool.A third investigator resolved any disagreement.RESULTS:A total of 62 articles were included.Based on the CONSORT statement,59.46%(22/37)of all entries had a reporting rate of less than 50%,mainly including“Identification as a randomized trial in the title(1/62,1.61%),”“How sample size was determined(7/62,11.29%),”“Implementation(1/62,1.61%),”“Blinding(1/62,1.61%),”and“Reports of Funding(4/62,6.45%).”According to the STRICTA checklist,29.41%(5/17)of all entries had a reporting rate of less than 50%,mainly including“Details of other interventions(7/58,12.07%),”“Setting and context of treatment(0/58,0%),”and“Description of participating acupuncturists(0/58,0%).”CONCLUSION:The reporting quality of randomized controlled trials on acupuncture and manipulation therapy for greater occipital neuralgia remains low.Future researchers need to make greater efforts to strictly adhere to the CONSORT statement and STRICTA checklist during trial design,implementation,and reporting.This will facilitate the standardization of research in this field and enhance the reliability and reproducibility of the research results.

文摘AIM:To investigate the causal relationship between dietary intake and myopia using Mendelian randomization(MR)analysis.METHODS:Genome-wide association study(GWAS)data from the IEU Open GWAS database were utilized to examine associations between myopia and various dietary factors.MR analysis,incorporating both univariable and multivariable approaches,assessed the impact of food intake on myopia risk through five analytical methods,with inverse variance weighted(IVW)serving as the primary reference.Sensitivity analyses,including heterogeneity assessment,horizontal pleiotropy evaluation,and leave-oneout analysis,were conducted to validate the MR findings.RESULTS:Univariable MR analysis identified a causal link between food intake and myopia.Consumption of breaded fish,canned soup,sweet biscuits,and certain fruits correlated with a lower risk of myopia,whereas intake of low-calorie hot chocolate and cereal was associated with an increased risk.Multivariable MR analysis further confirmed that breaded fish consumption exerted a direct protective effect against myopia,particularly when consumed alongside other dietary components.These findings highlight the intricate interplay between specific dietary factors and myopia development,offering valuable insights for further research.CONCLUSION:MR analysis provides evidence supporting a potential causal relationship between breaded fish intake and myopia,underscoring its relevance in targeted myopia prevention strategies.

文摘Domain randomization is a widely adopted technique in deep reinforcement learning(DRL)to improve agent generalization by exposing policies to diverse environmental conditions.This paper investigates the impact of different reset strategies,normal,non-randomized,and randomized,on agent performance using the Deep Deterministic Policy Gradient(DDPG)and Twin Delayed DDPG(TD3)algorithms within the CarRacing-v2 environment.Two experimental setups were conducted:an extended training regime with DDPG for 1000 steps per episode across 1000 episodes,and a fast execution setup comparing DDPG and TD3 for 30 episodes with 50 steps per episode under constrained computational resources.A step-based reward scaling mechanism was applied under the randomized reset condition to promote broader state exploration.Experimental results showthat randomized resets significantly enhance learning efficiency and generalization,with DDPG demonstrating superior performance across all reset strategies.In particular,DDPG combined with randomized resets achieves the highest smoothed rewards(reaching approximately 15),best stability,and fastest convergence.These differences are statistically significant,as confirmed by t-tests:DDPG outperforms TD3 under randomized(t=−101.91,p<0.0001),normal(t=−21.59,p<0.0001),and non-randomized(t=−62.46,p<0.0001)reset conditions.The findings underscore the critical role of reset strategy and reward shaping in enhancing the robustness and adaptability of DRL agents in continuous control tasks,particularly in environments where computational efficiency and training stability are crucial.

文摘BACKGROUND:Whether lipid-modifying drugs directly impact the outcome of sepsis remains uncertain.Therefore,systematic investigations are needed to explore the potential impact of lipid-related therapies on sepsis outcomes and to elucidate the underlying mechanisms involving circulating inflammatory cytokines,which may play critical roles in the pathogenesis of sepsis.This study aimed to utilize drug-target Mendelian randomization to assess the direct causal effects of genetically proxied lipid-modifying therapies on sepsis outcomes.METHODS:First,a two-sample Mendelian randomization study was conducted to validate the causal associations among high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),and sepsis.A subsequent drug-target Mendelian randomization study assessed the direct causal effects of genetical y proxied lipid-modifying therapies on the risk of sepsis,sepsis-related critical care admission,and sepsis-related death.The identified lipid-modifying drug targets were subsequently explored for direct causal relationships with 36 circulating inflammatory cytokines.Finally,enrichment analyses of the identified cytokines were conducted to explore the potential relationships of lipid-modifying drugs with the inflammatory response.RESULTS:Genetically proxied cholesteryl ester transfer protein(CETP) inhibitors were significantly associated with sepsis-related critical care admission(OR=0.84,95% CI [0.74,0.95],P=0.008,) and sepsisrelated death(OR=0.68,95% CI [0.52,0.88],P=0.004).The genetically proxied CETP inhibitors were strongly associated with the levels of 15 circulating inflammatory cytokines.Enrichment analyses indicated that CETP inhibitors may modulate inflammatory cytokines and influence the inflammatory response pathway.CONCLUSION:This study supports a causal effect of genetically proxied CETP inhibitors in reducing the risk of sepsis-related critical care admission and death.These findings suggest that the underlying mechanism may involve the modulation of some circulating inflammatory cytokines,influencing the inflammatory response pathway.

文摘Sudden and unforeseen seismic failures of coal mine overburden(OB)dump slopes interrupt mining operations,cause loss of lives and delay the production of coal.Consideration of the spatial heterogeneity of OB dump materials is imperative for an adequate evaluation of the seismic stability of OB dump slopes.In this study,pseudo-static seismic stability analyses are carried out for an OB dump slope by considering the material parameters obtained from an insitu field investigation.Spatial heterogeneity is simulated through use of the random finite element method(RFEM)and the random limit equilibrium method(RLEM)and a comparative study is presented.Combinations of horizontal and vertical spatial correlation lengths were considered for simulating isotropic and anisotropic random fields within the OB dump slope.Seismic performances of the slope have been reported through the probability of failure and reliability index.It was observed that the RLEM approach overestimates failure probability(P_(f))by considering seismic stability with spatial heterogeneity.The P_(f)was observed to increase with an increase in the coefficient of variation of friction angle of the dump materials.Further,it was inferred that the RLEM approach may not be adequately applicable for assessing the seismic stability of an OB dump slope for a horizontal seismic coefficient that is more than or equal to 0.1.

文摘Background:Electroacupuncture(EA)may affect the severity of hot flashes(HFs)associated with natural menopause and provide additional benefits for postmenopausal women.However,the evidence for its effectiveness in the management of early postmenopausal HFs remains inadequately understood.Objective:We designed this trial to assess the efficacy and safety of EA for relieving early postmenopausal HFs.Design,setting,participants and interventions:This randomized sham-controlled trial involved 72 women with HFs.The participants were divided equally into the intervention and control groups.The intervention group was treated with EA,while the control group was treated with sham acupuncture.The main acupoints used were Hegu(LI4),Guanyuan(RN4),Sanyinjiao(SP6),Taixi(KI3),Fuliu(KI7)and Shenshu(BL23).All participants received 18 treatment sessions,distributed across a 6-week period.The treatment was administered on three occasions per week,adhering to a fixed weekday schedule(Monday,Wednesday,Friday or Tuesday,Thursday,Saturday)with a minimum interval of one day between sessions.Each patient received a 12-week follow-up.Main outcome measures:The HF score was the primary outcome.Participants documented the frequency and severity of HFs in a 7-day symptom diary,which provided data for calculating the HF score.Secondary outcomes were the Menopause Rating Scale(MRS),Menopause-Specific Quality of Life Questionnaire(MENQOL),Pittsburgh Sleep Quality Index(PSQI)and Traditional Chinese Medicine Syndrome Score Scale(TCMSSS),as well as estradiol(E2),luteinizing hormone(LH)and folliclestimulating hormone(FSH)levels.Results:Both groups demonstrated significant reductions in HF scores after the treatment and during the follow-up(P<0.001).Immediately after completion of the 6-week treatment cycle and at 12 weeks postintervention,the HF scores were similar in both groups.At week 6,the intervention group showed significantly greater improvements in MRS,MENQOL(vasomotor,psychosocial,and physical),PSQI and TCMSSS scores(P<0.05).The improvements in the MENQOL(vasomotor,and psychosocial)and PSQI total scores persisted through the follow-up(P<0.05).However,the results showed no significant inter-or intragroup differences in sexual scores on the MENQOL(P>0.05).EA did not significantly decrease E2,LH or FSH levels compared to placebo.The incidence of adverse events was similar in both groups.Conclusion:EA does not significantly improve HFs in early postmenopausal patients.However,it enhances the quality of sleep and decreases menopausal symptoms across vasomotor,psychosocial and physical domains.Trial registration:Chinese Clinical Trial Registry(http://www.chictr.org.cn);Trial ID:Chi CTR2300072002.Please cite this article as:Wang HX,Yu XT,Hu J,Chen JJ,Mei YT,Chen YF.Electroacupuncture for hot flashes in early menopause:A randomized sham-controlled trial.J Integr Med.2025;23(5):519-527.?2025 Shanghai Yueyang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.Published by Elsevier B.V.All rights are reserved,including those for text and data mining,AI training,and similar technologies.
