ObjectiveTo investigate the mechanism by which Wumeiwan suppresses the development and progression of colorectal cancer（CRC） through the regulation of fatty acid metabolic reprogramming， thereby providing new experimental evidence for the prevention and treatment of CRC. MethodsA total of 120 C57BL/6 mice were randomly divided into the blank group， model group， Wumeiwan high-， medium-， and low-dose groups（54， 27， 13.5 g·kg^-1）， and the mesalazine group（0.01 g·kg^-1）， with 20 mice in each group. Except for the blank group， all mice were subjected to azoxymethane（AOM）/dextran sulfate sodium（DSS） treatment to establish an inflammation-associated CRC model. One week after AOM injection， mice in the treatment groups received intragastric administration of the designated drugs， while the blank and model groups received an equal volume of purified water， continuing until 20 d after the intervention endpoint. Hematoxylin-eosin（HE） staining was used to observe colonic histopathological alterations， and immunohistochemistry for vascular endothelial growth factor（VEGF） was performed to evaluate neovascularization and tumor invasion. Metabolomics combined with Kyoto Encyclopedia of Genes and Genomes（KEGG） and metabolite set enrichment analysis（MSEA） was applied to identify key CRC-related metabolic pathways， which were further validated by transcriptomic Gene Ontology（GO） enrichment and gene heatmap analysis. Subsequently， Western blot was performed to determine the expression levels of core proteins in these pathways， and immunofluorescence was used to analyze their localization and co-expression patterns in tissues， thereby elucidating the mechanism of Wumeiwan from multiple biological dimensions. ResultsCompared with the blank group， mice in the model group exhibited a significant decrease in body weight and a significant increase in the disease activity index（DAI） score（P<0.05）， with pronounced colonic mucosal damage accompanied by aggravated tumor invasion. Compared with the model group， Wumeiwan intervention markedly improved body weight loss and reduced DAI score， attenuated mucosal injury， and significantly decreased VEGF expression level（P<0.05）. Multi-omics analysis revealed that differential metabolites and genes across groups were commonly enriched in fatty acid metabolism， fatty acid biosynthesis， and other lipid-related pathways. Relative to the blank group， the model group showed significant upregulation levels of fatty acid synthesis-related genes， including sterol regulatory element-binding protein 1（SREBP1）， fatty acid synthase（FASN）， stearoyl-CoA desaturase 1（SCD1）， as well as saturated fatty acids（P<0.05）. Compared with the model group， treatment with Wumeiwan significantly reduced the expression of key genes involved in fatty acid metabolic pathways， including SREBP1， FASN， and SCD1（P<0.05）. Western blot results further confirmed that proteins in this pathway were significantly elevated in the model group， whereas they were markedly downregulated following Wumeiwan treatment（P<0.05）. Immunofluorescence analysis demonstrated enhanced co-localization of SREBP1 with the cancer-associated fibroblast（CAF） marker α-smooth muscle actin（SMA） in the model group， whereas this co-localization signal was attenuated after Wumeiwan intervention（P<0.05）. ConclusionWumeiwan can improve survival outcomes and alleviate colonic pathological damage in CRC mice， its therapeutic mechanism may be closely associated with the regulation of fatty acid metabolic reprogramming mediated by the SREBP1/FASN/SCD1 signaling pathway.

Objective To investigate the trends in the global burden due to cystic echinococcosis from 1990 to 2021, and to predict the global burden of cystic echinococcosis from 2022 to 2035, so as to provide insights into formulation of the cystic echinococcosis control strategy. Methods The global age-standardized prevalence, mortality, disability-adjusted life years (DALYs) rates and their 95% uncertainty intervals (UI) of cystic echinococcosis from 1990 to 2021 were captured from the Global Burden of Disease Study 2021 (GBD 2021) database, and the trends in the global burden of cystic echinococcosis from 1990 to 2021 were analyzed using the Joinpoint regression model. The associations between the global burden of cystic echinococcosis and socio-demographic index (SDI) were examined using a smoothing spline model and frontier analysis, and the global burden of cystic echinococcosis was projected from 2022 to 2035 using the Bayesian age-period-cohort (BAPC) model. Results The global agestandardized prevalence, mortality and DALYs rates of cystic echinococcosis were 7.69/10⁵ [95% UI: (6.27/10⁵, 9.51/10⁵)], 0.02/10⁵ [95% UI: (0.01/10⁵, 0.02/10⁵)], and 1.32/10⁵ [95% UI: (0.99/10⁵, 1.69/10⁵)] in 2021. The global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a rise by 0.14% per year from 1990 to 2021, and the global age-standardized mortality and DALYs rates of cystic echinococcosis appeared a tendency towards a decline by 4.68% and 4.01% per year from 1990 to 2021, respectively. Joinpoint regression analysis showed that global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a decline from 1990 to 2000 [annual percent change (APC) = −0.66%, 95% confidence interval (CI): (−0.70%, −0.61%)] and from 2005 to 2015 [APC = −0.88%, 95% CI: (−0.93%, −0.82%)], and towards a rise from 2000 to 2005 [APC = 3.68%, 95% CI: (3.49%, 3.87%)] and from 2015 to 2021 [APC=0.30%, 95%CI: (0.19%, 0.40%)].Theagestandardized prevalence (r = −0.17, P < 0.05), mortality (r = −0.67, P < 0.05) and DALYs rates of cystic echinococcosis (r = −0.60, P < 0.05) all correlated negatively with SDI across 21 geographical regions from 1990 to 2021, and the age-standardized mortality (r = −0.61, P < 0.05) and DALYs rates (r = −0.44, P < 0.05) both correlated negatively with SDI across 204 countries and territories in 2021. Frontier analysis revealed that the age-standardized DALYs rate of cystic echinococcosis was still not in line with the frontier in some high-SDI countries or territories. In addition, the global age-standardized prevalence was projected with the BAPC model to appear a tendency towards a rise among both men [estimated annual percent change (EAPC) = 0.18%, 95% CI: (0.13%, 0.23%)] and women [EAPC = 0.29%, 95% CI: (0.24%, 0.34%)] from 2022 to 2035, and the global age-standardized mortality [men: EAPC = −4.71%, 95% CI: (−4.71%, −4.37%); women: EAPC = −4.74%, 95% CI: (−4.74%, −4.74%)] and DALYs rates [men: EAPC = −3.35%, 95% CI: (−3.36%, −3.34%); women: EAPC = −3.17%, 95% CI: (−3.18%, −3.16%)] were projected to appear a tendency towards a decline among both men and women. Conclusions The global burden of cystic echinococcosis appeared an overall tendency towards a decline from 1990 to 2021; however, the global prevalence of cystic echinococcosis is projected to appear a tendency towards a rise from 2022 to 2035. Intensified cystic echinococcosis control programmes are recommended.

Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

OBJECTIVE: To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease. METHODS: The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points. RESULTS: The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower. CONCLUSION It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

Objective:To analyze the trends and research hotspots in English publications from China′s anesthesiology discipline in international journals from 2000 to 2023 using the bibliometric analysis.Methods:Based on the results retrieved from the Science Citation Index Expanded database covering English publications from China′s anesthesiology discipline in international journals from January 2000 to December 2023, CiteSpace 6.3.R1 and VOSviewer 1.6.20.0 were employed to analyze the annual publication counts, institutions, authors, co-cited references, and keywords, etc. with knowledge graph generated.Results:A total of 53, 039 articles published in English from January 2000 to December 2023 were included. The annual number of articles published in English showed an overall increasing trend year by year. Basic research articles exhibited a phase of slow growth during 2000-2007, entered a period of accelerated growth from 2008, and demonstrated a slightly decreased trend by 2023. The number of clinical research articles increased rapidly since 2008, was equivalent to the basic research articles by 2020, surpassed basic research articles by 2023 and became the mainstream research direction of anesthesiology discipline. Among clinical research publications, case series studies predominated from 2000 to 2022, and cohort studies exceeded case series for the first time in 2023, ranking second only to the randomized controlled trials. Research hotspots in anesthesiology discipline predominantly focused on the relationship of neuropsychiatry to anesthesia, pain management, cardiovascular surgery and organ injury, COVID-19 pandemic and patient safety. In terms of journals, Medicine was the journal with the largest number of publications, with 1, 345 publications in 2023 and an impact factor of 1.3. American journals dominated the top 15 highly productive journals, and Anesthesiology had the highest h-index (60) and g-index (98) with an impact factor of 9.1. In terms of domestic high-yield institutions, Shanghai Jiao Tong University topped the list, publishing about 1, 200 papers between 2000 and 2023, followed by Sichuan University (about 850) and Capital Medical University (about 720). Conclusions:China′s anesthesiology research has demonstrated a meteoric rise in both the number of papers published and cited frequency, reflecting ascending scientific academic levels and innovation capacity in the the international arena. While acknowledging this quantitative expansion, recognition is warranted that enhancing research quality and international impact remains imperative to narrow the gap with advanced nations and gradually achieve advancement.

OBJECTIVE To investigate the effects of different sterilization methods on 3D-printed polylactic acid(PLA)guide plates for orthopedic surgery,and to analyze their physical properties,microbial contamination,structural performance and bio compatibility after sterilization.METHODS PLA guide plates for orthopedic surgery were prepared with 3D printing technology and divided into a blank group,a hydrogen peroxide plasma steriliza-tion group,an ethylene oxide sterilization group and a pressure steam sterilization group.Before and after sterili-zation,the changes in volume and weight of the surgical guide plates were measured,microbial detection was con-ducted,structural changes were observed with a laser scanning confocal microscope,and cell co-culture was con-ducted to evaluate biocompatibility,thereby the effects of different sterilization methods were assessed.RESULTS The three sterilization methods had no significant effect on the volume and weight of PLA surgical guide plates.Microbial detection showed that all three sterilization methods were effective in killing bacteria,and bacte-rial cultures were negative.Laser confocal scanning microscopy revealed that sterilization treatment caused certain changes to the microstructure of the surgical guide plates,but high-temperature sterilization had a more pro-nounced effect on the deformation of the guide plate edges.Cell co-culture results indicated that the surgical guide plates treated with the three sterilization methods exhibited acceptable cytotoxicity and had little effect on cell pro-liferation.CONCLUSIONS All three sterilization methods cause microstructural changes to the surgical guide plate.Among them,pressure steam sterilization significantly deforms the structure of the guide plate,directly af-fecting its precise positioning of mutual spatial distances,angular relationships and orientation during surgery.Al-though hydrogen peroxide plasma sterilization does not cause significant deformation,ethylene oxide sterilization has the least impact on material properties and structural stability while ensuring the sterilization effect of PLA surgical guide plates.

Objective To analyze the clinical characteristics and explore the potential mechanisms under-lying acute wheezing associated with respiratory syncytial virus(RSV)and human rhinovirus(HRV)infections in infants.Methods A retrospective analysis was conducted on 560 infants who consecutively presented to the emer-gency department of Qingdao University Affiliated Women and Children's Hospital between January 2022 and December 2024 with acute exacerbation of wheezing caused by RSV and/or HRV infection;these infants constituted the infection group.A control group of 120 healthy infants who underwent routine physical examinations at the same hospital during the same period was also included.Multiplex PCR amplification sequencing technology was employed to detect respiratory pathogens via nucleic acid analysis.The infection group was further classified into the RSV-only group(n=248),the HRV-only group(n=186),and the co-infection group(HRV+RSV,n=126).One-way analysis of variance(ANOVA)was used to compare body mass index(BMI),peripheral blood white blood cell(WBC)count,neutrophil count,lymphocyte count,C-reactive protein(CRP)levels,and concentrations of interleukin(IL)-1β,IL-6,Toll-like receptor 4(TLR4),NOD-like receptor protein 3(NLRP3)inflamma-some,and matrix metalloproteinase-9(MMP-9)across the groups.Additionally,comparisons were made regarding gender distribution,severity of wheezing,history of wheezing,history of eczema,parental allergic history,oxygen supplementation requirements,and presence of concurrent pulmonary infection among the infected infants.Based on wheezing severity,the infection group was further divided into a severe wheezing group and a mild wheezing group.Clinical characteristics and biological indicators were analyzed and compared between these two groups to identify potential independent risk factors.Pearson correlation analysis was performed to evaluate the association between peripheral blood levels of IL-6,NLRP3,and MMP-9 and the severity of acute wheezing exacerbation in children.Results A one-way ANOVA indicated statistically significant differences in WBC count,neutrophil count,CRP,IL-1β,IL-6,TLR4,NLRP3,and MMP-9 levels across the study groups(all P<0.001).Both the RSV and co-infection groups demonstrated significantly higher rates of severe wheezing,oxygen requirement,and prolonged wheezing duration compared to the HRV group(all P<0.05).Among these,the co-infection group exhibited the highest oxygen requirement rate,although the duration of wheezing was shorter than that observed in the RSV group(P<0.05).The incidence of concurrent pulmonary infection was significantly greater in the RSV group compared to the HRV group(P<0.05).Additionally,the proportion of infants with a prior history of wheez-ing was significantly higher in the RSV group than in both the HRV and co-infection groups(P<0.05).Both the RSV and co-infection groups showed a significantly higher prevalence of eczema history among infants compared to the HRV group(P<0.05).Moreover,the co-infection group had a significantly higher proportion of parental allergic history compared with both the RSV and HRV groups(P<0.05).Clinical data analysis stratified by wheezing severity revealed that RSV was the most commonly detected virus among the enrolled infants,particularly in those presenting with severe wheezing(χ2=3.940,P=0.002).The severe wheezing group exhibited significantly higher rates of prior wheezing,history of eczema,parental allergy,need for oxygen supplementation,and concurrent pulmonary infections compared to the mild wheezing group(P<0.001).Furthermore,the duration of wheezing was significantly prolonged in the severe group relative to the mild group(t=2.058,P=0.040).Levels of IL-6,NLRP3,and MMP-9 were also significantly elevated in the severe wheezing group(P<0.05).Multivariate logistic regression analysis revealed that RSV infection,along with elevated levels of IL-6,NLRP3,and MMP-9,were independent risk factors associated with severe wheezing(OR=3.217,1.023,1.022,and 1.056,respectively;all P<0.05).In children with RSV/HRV infection,the severity of acute wheezing demonstrated a positive correlation with NLRP3 and MMP-9 levels(P<0.05).The Pearson correlation coefficient between NLRP3 and MMP-9 was r=0.238(P<0.001),indicating a weak yet statistically significant positive relationship.Conclusions RSV may provoke more severe respiratory inflammatory responses and clinical manifestations compared to HRV.Individuals with a genetic predisposition to allergies or a pre-existing history of respiratory conditions may experience height-ened severity of wheezing following viral infection.The NLRP3 inflammasome may further intensify airway inflam-mation and remodeling through the promotion of MMP-9 release.These mechanisms may collectively contribute to the pathogenesis of acute wheezing episodes and subsequently influence the progression of respiratory diseases.
