Objective To systematically analyze the spatiotemporal distribution characteristics and epidemiological trends of tracheal, bronchus, and lung cancer (TBL) disease burden attributed to air pollution globally and in China and the United States from 1990 to 2021, and to assess the patterns of disease burden changes from 2022 to 2031 based on predictive models, providing a scientific basis for formulating targeted TBL prevention and control strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we analyzed the disease burden data of TBL attributed to air pollution globally and in China and the United States from 1990 to 2021. R Studio 4.3.2 software was used to analyze the corresponding trends and the Bayesian age-period-cohort (BAPC) prediction model was used to predict the status of the disease burden of TBL attributed to air pollution in the world and in China and the United States from 2022 to 2031. Results In 2021, China had the highest number of deaths and disability-adjusted life years attributed to air pollution (211 400 patients and 4.8947 million person-years), followed by the United States (6 000 patients and 124 300 person-years). The age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life years rate (ASDR) of TBL due to air pollution in the world and in China and the United States showed a decreasing trend. From 1990 to 2021, the ASMR and ASDR of TBL in China due to air pollution were much higher than those in the United States and the global average. In terms of gender, from 1990 to 2021, the disease burden of male patients with TBL attributed to air pollution was much higher than that of female patients. The BAPC prediction model showed that from 2022 to 2031, the ASMR and ASDR of TBL attributed to air pollution showed an upward trend globally, while they showed a downward trend in China and the United States. Conclusion Over the past 30 years, the air pollution-related TBL disease burden in the world and in China and the United States has continued to decline, but China's disease burden is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the population aged ≥50 years being high-risk groups. In the future, the global disease trend may reverse and rise, while China and the United States are expected to continuously decline. However, precise prevention and control for high-risk groups remains a key challenge.

Objective:To investigate the effects of botulinum toxin A (BTX-A) injection on ocular surface in patients with blepharospasm and dry eye.Methods:In this prospective study, 56 patients (83 eyes) with essential blepharospasm who were treated with BTX-A in the Department of Ophthalmology of Jiaxing Hospital of Traditional Chinese Medicine from April 2020 to January 2022 were included. The patients were divided into blepharospasm with dry eye group (group A, 50 eyes) and simple blepharospasm group (group B, 33 eyes) according to whether they were accompanied by dry eye. The Oculus Keratograph was used to evaluate tear meniscus height (TMH), tear break-up time (BUT), ocular bulbar redness, and corneal fluorescein staining. The OPD-Scan III analyzer was used to measure the corneal surface regularity index. The Ocular Surface Disease Index and meibomian gland analysis were performed to diagnose dry eye before treatment. Paired t-tests and Wilcoxon signed-rank tests were conducted to analyze the data. In patients with unilateral conditions, the ocular surface data of the affected and healthy eyes were compared before treatment. The severity of blepharospasm was evaluated in both groups before treatment and 1 week after treatment. Results:Among the 56 patients, 57.1% (32/56) were diagnosed with dry eye. One week after BTX-A injection treatment, both groups demonstrated varying degrees of improvement in their conditions. In patients with unilateral blepharospasm, pre-treatment ocular surface examinations indicated that the affected eye had a lower tear BUT of (6.67 ± 3.86) seconds and a lower TMH of (0.18 ± 0.07) mm compared with the healthy eye, which showed (10.20 ± 5.95) seconds for BUT and (0.20 ± 0.05) mm for TMH ( t = -3.94, -2.44, both P < 0.05). Additionally, the ocular bulbar redness value was significantly higher in the affected eye [(1.75 ± 0.38)] than in the healthy eye [(1.65 ± 0.47), t = 2.16, P < 0.05]. After treatment, both groups exhibited significant increases in BUT and TMH compared with their pre-treatment values ( t = -6.27, -4.21, -2.56, -3.12, all P < 0.05). Furthermore, both groups showed significant decreases in ocular bulbar redness values compared with pre-treatment values ( t = 3.04, 3.32, both P < 0.05). In group A, the corneal fluorescein staining score post-treatment was significantly lower than the pre-treatment value ( Z = 2.10, P < 0.05). However, in group B, the FL score did not show a significant difference between pre-treatment and post-treatment. ( Z = 0.03, P > 0.05). There were also no significant differences in the surface regularity index between the two groups both before and after treatment ( t = 1.35, 0.65, both P > 0.05). Conclusions:Blepharospasm can affect the stability of the tear film on the ocular surface, and BTX-A injection can help relieve dry eye caused by essential blepharospasm.

Objective To investigate the diagnostic accuracy and clinical applicability of the Linknet-VGG16 deep learning algorithm for measuring the effective optical zone(EOZ)after corneal refractive surgery.Methods This single-center retrospective cohort study included 69 patients(69 eyes)who underwent femtosecond laser-assisted in situ kerato-mileusis(FS-LASIK)(34 eyes)or small incision lenticule extraction(SMILE)(35 eyes)at the Refractive Surgery Center of Affiliated Zhengzhou Aier Eye Hospital of Henan University from June 2023 to June 2024.Data from the right eyes of all patients were selected for statistical analysis.During the surgery,patients in the FS-LASIK group adopted the VisuMax fem-tosecond laser system combined with the Amaris 750S excimer laser system,while those in the SMILE group only used the VisuMax femtosecond laser system.A total of 276 Pentacam images were re-examined postoperatively.A Linknet segmenta-tion model based on the VGG16 encoder was constructed,and image normalization techniques were applied to accelerate model convergence.Model performance was assessed using accuracy,intersection over union(IoU),and the Dice coeffi-cient.The traditional EOZ measurement method based on corneal tangential curvature served as the reference standard.Bland-Altman analysis was conducted to evaluate consistency across all images and within each group,and the time effi-ciency of both methods was compared.Results Six representative medical image segmentation architectures(U-Net,U-Net++,DeepLabv3-ResNet50,DeepLabv3+-ResNet50,Unet-Densenet169,and Linknet-VGG16)were systematically evaluated.The Linknet-VGG16 model demonstrated superior performance over the other 5 models in pixel-level accuracy,IoU and Dice coefficient,which were 99.83％,99.48％and 99.74％,respectively.Although there was no significant differ-ence in accuracy and Dice coefficient between Linknet-VGG16 and U-Net models(whose accuracy was 99.82％and Dice coefficient was 99.72％),the inference speed of the U-Net model(62.46 ms)was 31.76％slower than that of the Linknet-VGG16 model(42.62 ms).The evaluation results of a clinically applicable comprehensive scoring model(weights:accura-cy 20％,IoU 20％,Dice coefficient 20％,speed 25％,model size 15％)showed that the Linknet-VGG16 model achieved a score of 88.01,surpassing other architectures(U-Net:86.29;DeepLabv3+-ResNet50:80.41;DeepLabv3-ResNet50:73.82;U-Net++:73.22;Unet-Densenet169:66.66).Bland-Altman analysis revealed that the mean difference of the 136 images in the FS-LASIK group was 0.01 mm[95％limits of agreement(LoA):-0.36 to 0.35 mm],with 96.3％of data points falling within the LoA.The mean difference of the 140 images in the SMILE group was-0.01 mm(95％LoA:-0.36 to 0.33 mum),with 95.7％of data points falling within the LoA.The mean difference of all 276 images was 0.00 mm(95％LoA:-0.36 to 0.34 mm),with 96.4％of data points falling within the LoA.These results indicated excellent consistency.The average measurement time per image using the traditional EOZ measurement method was 13.00 minutes,whereas the deep learning model required only 3.22 seconds.Conclusion The traditional EOZ measurement method based on corne-al tangential curvature exhibits good consistency with the fully automatic EOZ measurement method based on deep learning algorithms,achieving high image recognition accuracy.Additionally,the deep learning algorithm significantly reduces measurement time,compared with the traditional method based on corneal tangential curvature.

Objective The purpose of writing the"expert consensus on humanistic care for patients in hospice care"(hereinafter referred to as the"consensus")aims to standardize the practice of humanistic care in the field of hospice care,ensuring that humanistic care is integrated throughout the entire service process for hospice care patients and their families.Methods A systematic search was conducted in domestic and foreign databases for literature related to hospice care and humanistic care,including guidelines,expert consensuses,systematic reviews or Meta-analyses,and evidence summaries.High-quality evidence was evaluated,extracted,and summarized to form the initial draft of the"consensus".From June to October 2024,20 experts from the fields of hospice care,nursing humanities,and evidence-based nursing were invited to participate in 1 round of expert consultation.Among them,13 experts were selected for 2 rounds of expert demonstration meetings.After collating and analyzing the experts' opinions,the initial draft was revised and refined,ultimately resulting in the final version of the"consensus".Results The effective response rate of the consultation questionnaire was 100％,with expert authority coefficient of 0.880,judgment coefficient of 0.935,and familiarity level of 0.825.The Kendall harmony coefficient of the expert consultation was 0.134(P＜0.05).The"consensus"consisted of 13 aspects,including the targets and objectives,principles,institutional guarantees,environmental requirements,etc.Conclusion This"consensus"possesses strong scientific rigor and practicality,which can provide guidance and references for the practice of humanistic care in the field of hospice care,promoting the standardization and humanization of hospice care services.

To investigate the effects ofS-Adenosylmethionine(SAM)on liver injury induced by carbon tetrachloride(CCl4)in mice,In this study,60 C57BL/6 mice were randomly divided into CON group,CCl4 group,low dose group(CCl4+SAM-L,50 mg/kg SAM),medium dose group(CCl4+SAM-M,100 mg/kg)and high dose group(CCl4+SAM-M,200 mg/kg).Except CON group,mice in other groups were intraperitoneally injected with CCl4(10 mL/kg,0.2％),and mice in CON group were injected with equal volume olive oil,3 times a week for 4 weeks,to establish mouse liver injury model.At the same time,mice in low,medium and high dose groups were given 100 μL SAM,CON group and CCl4 group were given equal volume PBS for 4 weeks.The results showed that CCl4 promoted liver fibrosis and increased serum ALT,AST and TBIL levels(P＜0.05).Different doses of SAM significantly alleviated liver fibrosis injury and decreased serum ALT,AST and TBIL levels(P＜0.05).Compared with CON group,CCl4 significantly decreased the liver T-AOC,SOD,CAT and GSH-Px levels(P＜0.05),and increased the liver MDA level(P＜0.05).Compared with CCl4 group,the levels of T-AOC,SOD,CAT and GSH-PX in liver of mice in CCl4+SAM group were significantly increased(P＜0.05),while the level of MDA was significantly decreased(P＜0.05).Compared with CON group,liver levels of IL-6,IL-1β and TNF-α in CCl4 group were significantly increased(P＜0.05).Compared with CCl4 group,different doses of SAM could significantly reduce the levels of IL-6,IL-1β and TNF-α in liver of mice(P＜0.05).Compared with CON group,the expressions of Nrf2,NQO-1 and HO-1 genes in liver of CCl4 group were decreased(P＞0.05),while the expression of Keap1 gene was significantly increased(P＞0.05).Compared with CCl4 group,medium and high doses of SAM significantly increased the expressions of Nrf2,NQO-1 and HO-1 genes in liver of mice(P＜0.05),and decreased the expres-sion of Keap1 gene(P＞0.05).Compared with CON group,the contents of acetic acid,propionic acid and butyric acid in cecum of CCl4 group were significantly decreased(P＜0.05).Compared with CCl4 group,the contents of propionic acid and butyric acid in high-dose SAM group were sig-nificantly increased(P＜0.05).Microbial analysis showed that CCl4 significantly decreased the rel-ative abundance of Akkermansia and Prevotellaceae_NK3B31_group(P＜0.05),and changed the composition of intestinal microorganisms.These results indicate that SAM regulates the gene ex-pression of Nrf2 antioxidant signaling pathway to a certain extent,increases intestinal SCFAs con-tent,regulates intestinal microbial structure,and thus alleviates liver injury,oxidative stress and inflammation caused by CCl4.This study provides reference and theoretical basis for SAM in the treatment and remission of drug-induced liver injury.

Objective To explore the application effect of constructing a data sharing-based multidrug-resistant or-ganism(MDRO)information reminder system combined with multidisciplinary standardized measures on the whole-process closed-loop management of MDRO.Methods Hospitalized patients from whom MDRO were detected from January 1 to July 31,2024 were taken as the control group,those from August 1,2024,to May 31,2025 were as the intervention group.The control group adopted the traditional manual reporting mode for MDRO,while the in-tervention group adopted the combination of MDRO reminder system and multidisciplinary management mode.Differences in isolation order issuing rate for MDRO and process-and outcome-indicators for multidisciplinary spe-cialty before and after system implementation were compared.Results After implementing information reminder system combined with multidisciplinary measures,issuing rates of ≤24 hour and＜4 hour MDRO isolation orders in the intervention group were both higher than in the control group([90.20％vs 65.23％,P＜0.05],[80.64％vs 55.08％,P＜0.001],respectively).Antimicrobial use rate in the intervention group was lower than in the con-trol group(36.27％vs 43.41％),with a statistically significant difference(P＜0.05).The implementation rates of MDRO prevention and control measures,pathogen detection rates,and fluorescence labeling clearance rates in the intervention group were all higher than those in the control group,all with statistically significant differences(all P＜0.05).The detection rate of MDRO decreased compared with the control group(10.83％vs 16.49％),and the in-cidence of MDRO healthcare-associated infection in the intervention group was lower than that in the control group(0.09％vs 0.19％),both with statistically significant differences(both P＜0.001).The treatment expense in the intervention group reduced by 27 422 Yuan compared with the control group.Conclusion This study constructed an MDRO reminder system,realized full-chain monitoring system for the multidisciplinary MDRO information interac-tion platform,strengthened multidisciplinary in-depth integration,and improved the prevention and control effect for MDRO.

Objective To investigate the relationship between cyclin A2 (CCNA2) and the prognosis of colon cancer, and its possible mechanism from the perspective of immune infiltration. Methods We downloaded the transcriptome data of colon cancer patients from The Cancer Genome Atlas database. Clinicopathological feature analysis and survival analysis were performed based on the expression levels of CCNA2. A total of 75 specimens of colon cancer and normal tissues were collected, and the expression level of CCNA2 was analyzed using immunohistochemical methods. Multivariate analysis was conducted to explore its relationship with clinicopathological features. Gene Set Enrichment Analysis (GSEA) was used to assess the potential molecular functions of CCNA2 in colon cancer. CIBERSORT algorithm was applied to calculate the correlation between CCNA2 and immune-cell infiltration in colon cancer. Results Database and immunohistochemical analyses indicated that CCNA2 was expressed at a significantly higher level in colon cancer tissues than normal tissues (P<0.001). The overall survival, disease-specific survival, and progression-free interval were all longer in the group with high CCNA2 expression than the group with low expression (all P<0.05). In tumor tissues, the expression level of CCNA2 decreased with increased pathological and TNM stages (P<0.05). The expression level of CCNA2 in normal tissues was consistently lower than that in colon cancer tissues across all clinical stages (all P<0.001). GSEA suggested that Wnt/β-catenin, KRAS, and other signaling pathways were enriched when CCNA2 was lowly expressed. CIBERSORT analysis revealed an increase in the infiltration of immune cells such as regulatory T cells and macrophages M0 when CCNA2 expression was low. Conclusion CCNA2 is highly expressed in colon cancer and closely associated with grade of pathology and TNM stage. It may recruit regulatory T cells through the KRAS and Wnt/β-catenin pathways, thereby reducing immune-cell infiltration and promoting colon cancer progression, leading to poor prognosis.

Objective:To analyze the efficacy and prognostic factors of fractionated stereotactic radiotherapy (FSRT) for patients with breast cancer brain metastases (BCBM).Methods:Medical records and follow-up data of BCBM patients who underwent FSRT in Cancer Hospital Chinese Academy of Medical Sciences, Shenzhen Center and Shenzhen People's Hospital from August 2019 to May 2023 were collected. The R Studio platform of the R version 4.2.1 statistical software was applied to analyze patients' baseline characteristics, 1- and 2-year local brain control (LBC), overall survival (OS) and distant brain control (DBC) and corresponding median failure-free survival, draw survival curve using Kaplan-Meier method. Prognostic factors were screened by univariate analysis and multivariate analysis (Cox regression).Results:Cumulatively, 52 patients (163 metastases in total) had a median survival follow-up of 22.1 months, 83% were<60 years old. Molecular typing: 13 cases (25%) were positive for human epidermal growth factor receptor 2 (HER2+) / hormone receptor negative (HR-), 2 cases (4%) were luminal A, 26 cases (50%) were luminal B, and 11 cases (21%) were triple negative. The median number of brain metastases was 2 (range: 1 - 17). Follow-up outcomes: the median OS was 34.0 months, with 1- and 2-year OS rates of 85.6% and 65.4%, respectively; the median LBC was 20.6 months, with 1- and 2-year LBC rates of 79.2% and 45.2%, respectively; and the median DBC was 10.3 months, with 1- and 2-year DBC rates of 46.7% and 28.9%, respectively. During follow-up, 13 patients underwent salvage local therapy (10 FSRT); 5 developed radiation necrosis (1 symptomatic). Prognostic factor analysis: absence of extracranial organ metastases (compared with ≥3) was a protective factor for OS, P<0.05. For LBC, fewer (1 - 2) extracranial organ metastases (compared with ≥3), and single brain metastasis (compared with ≥2) were favorable prognostic factors , while N 3 staging upon initial diagnosis was a poor prognostic factor (all P<0.05). For DBC, brain metastasis after surgery was a good prognostic factor, while complicated with lung metastasis and asymptomatic brain metastasis at the first diagnosis were poor prognostic factors (all P<0.05). Conclusions:FSRT yields relatively good LBC and poor DBC for BCBM patients. A certain percentage of patients require salvage FSRT during follow-up, but OS is maintained acceptable and the radiation necrosis is tolerable. Among the prognostic factors, the absence of extracranial metastatic organs is a good prognostic factor for OS; patients with single brain metastasis, fewer extracranial metastatic organs, and non-N 3 staging upon initial diagnosis can obtain better LBC after FSRT.

To investigate the effects ofS-Adenosylmethionine(SAM)on liver injury induced by carbon tetrachloride(CCl4)in mice,In this study,60 C57BL/6 mice were randomly divided into CON group,CCl4 group,low dose group(CCl4+SAM-L,50 mg/kg SAM),medium dose group(CCl4+SAM-M,100 mg/kg)and high dose group(CCl4+SAM-M,200 mg/kg).Except CON group,mice in other groups were intraperitoneally injected with CCl4(10 mL/kg,0.2％),and mice in CON group were injected with equal volume olive oil,3 times a week for 4 weeks,to establish mouse liver injury model.At the same time,mice in low,medium and high dose groups were given 100 μL SAM,CON group and CCl4 group were given equal volume PBS for 4 weeks.The results showed that CCl4 promoted liver fibrosis and increased serum ALT,AST and TBIL levels(P＜0.05).Different doses of SAM significantly alleviated liver fibrosis injury and decreased serum ALT,AST and TBIL levels(P＜0.05).Compared with CON group,CCl4 significantly decreased the liver T-AOC,SOD,CAT and GSH-Px levels(P＜0.05),and increased the liver MDA level(P＜0.05).Compared with CCl4 group,the levels of T-AOC,SOD,CAT and GSH-PX in liver of mice in CCl4+SAM group were significantly increased(P＜0.05),while the level of MDA was significantly decreased(P＜0.05).Compared with CON group,liver levels of IL-6,IL-1β and TNF-α in CCl4 group were significantly increased(P＜0.05).Compared with CCl4 group,different doses of SAM could significantly reduce the levels of IL-6,IL-1β and TNF-α in liver of mice(P＜0.05).Compared with CON group,the expressions of Nrf2,NQO-1 and HO-1 genes in liver of CCl4 group were decreased(P＞0.05),while the expression of Keap1 gene was significantly increased(P＞0.05).Compared with CCl4 group,medium and high doses of SAM significantly increased the expressions of Nrf2,NQO-1 and HO-1 genes in liver of mice(P＜0.05),and decreased the expres-sion of Keap1 gene(P＞0.05).Compared with CON group,the contents of acetic acid,propionic acid and butyric acid in cecum of CCl4 group were significantly decreased(P＜0.05).Compared with CCl4 group,the contents of propionic acid and butyric acid in high-dose SAM group were sig-nificantly increased(P＜0.05).Microbial analysis showed that CCl4 significantly decreased the rel-ative abundance of Akkermansia and Prevotellaceae_NK3B31_group(P＜0.05),and changed the composition of intestinal microorganisms.These results indicate that SAM regulates the gene ex-pression of Nrf2 antioxidant signaling pathway to a certain extent,increases intestinal SCFAs con-tent,regulates intestinal microbial structure,and thus alleviates liver injury,oxidative stress and inflammation caused by CCl4.This study provides reference and theoretical basis for SAM in the treatment and remission of drug-induced liver injury.

ObjectiveTo characterize the evidence distribution and methodological quality of randomized controlled trials （RCTs） on oral Chinese herbal medicine （CHM） for atopic dermatitis （AD） based on evidence mapping. MethodsSeven databases （CNKI， Wanfang Data， VIP， CBM， Cochrane Library， PubMed， and Embase） and the Chinese Clinical Trial Registry were searched for the RCTs in Chinese and English. Evidence distribution was presented graphically and textually， and methodological quality was assessed via the Cochrane Risk of Bias tool （ROB 1.0）. ResultsA total of 168 RCTs were included. The number of annual publications showing an increasing trend， and 72.6% RCTs had sample sizes of 51-100 participants. The studies evaluated 108 distinct CHM interventions categorized as decoctions， granules， Chinese patent medicines， and extracts. Compound Glycyrrhizin was the most frequently used， followed by Xiaofengsan and Chushi Weiling decoction. Among the RCTs， 57.1% had the treatment courses of 4-8 weeks. Outcome measures predominantly focused on clinical response rate， skin lesion severity scores， and adverse events， with less attention to TCM symptom scores， skin barrier function， and relapse rates. The overall risk of bias was generally high. ConclusionWhile CHM for AD is a research hotspot and demonstrates clinical advantages， the related studies have problems such as unclear clinical positioning， poor research standardization and methodological quality， and insufficient prominence of TCM clinical advantages. Large-sample， methodologically rigorous， and high-quality studies are needed to enhance the evidence base for CHM in treating AD.
