Objective To analyze the disease burden and trends of bladder cancer in China and globally from 1992 to 2021.  Methods Using the GBD 2021 database, the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) rates of bladder cancer in China and globally from 1992–2021 were analyzed. Average annual percentage change (AAPC) was calculated using Joinpoint regression. Subgroup analyses by sex and age were conducted, and a Bayesian age-period-cohort (BAPC) model was used to predict trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for the next 15 years.  Results In 2021, China reported 106 000 new cases (ASIR: 5.14/100 000), 571 000 prevalent cases (age-standardized prevalence rate, ASPR: 26.61/100 000), 43 000 deaths (ASMR: 2.34/100 000), and a DALY rate of 45.31/100 000. From 1992–2021, China showed upward trends in ASIR and ASPR but declines in ASMR and DALYs, while global ASIR, ASMR, and DALYs decreased overall with slow ASPR growth. The peak cases in China and globally were both concentrated in the 65-79 age group, with a significantly higher burden on males than females. In China, smoking-related ASMR and ASDR exceeded global averages and rose, whereas high glucose-related indexes were lower and declined. Projections for 2021–2036 indicated that the global incidence and mortality rates would be rising, but ASIR/ASPR would be declining, while in China, the incidence rate would continue to rise, and the mortality rate will stabilize, with a significant increase in ASIR and a gradual decrease in ASPR.  Conclusion From 1992 to 2021, the incidence of bladder cancer in China has shown a continuous upward trend and is projected to persist in the future, with significant gender and age differences. Particular attention should be given to elderly males aged 85-89. The disease burden of bladder cancer attributable to smoking continues to rise, highlighting the urgent need to strengthen tobacco control policies.

This study aims to review the current status and development trends of digital TCM (Traditional Chinese Medicine) specimen museums, providing a theoretical basis for their future construction. By systematically organizing literature and materials, practical experiences in platform architecture design, content planning, and technical implementation were summarized. The research results show that digital technology has significant application value in the TCM field. Currently, some Food and Drug Control Institutes have formed diverse construction achievements by integrating regional characteristics with technological innovation. However, current TCM specimen museums generally still face many challenges, such as insufficient digitalization. In conclusion, the digitalization of TCM specimen museums has become an inevitable trend in the industry. Targeted measures are urgently needed to solve existing problems and promote the sustainable development of digital TCM specimen museums. It is suggested to strengthen the standardization of data collection and storage, deepen the integration of technologies such as 3D, AR, and AI into the construction of specimen museums, and at the same time promote the spatial design combining regional culture with TCM. This will help create "one museum with one feature for one region" digital TCM specimen museums, further promoting their sustainable development and facilitating the digital inheritance of TCM.

Background: This study was performed to characterize the incidence, costs, and risk factors associated with renal and cardiovascular adverse outcomes following primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI). Methods: Patients with STEMI who underwent pPCI using iso-osmolar contrast were enrolled at 39 centers. The incidence of acute kidney injury (AKI) and major adverse renal and cardiovascular events (MARCE) was analyzed, as well as inpatient costs. Logistic regression analysis was performed to identify risk factors. Results: Among 2,293 patients, the incidence of AKI and MARCE within 72 hours post-pPCI was 4.14% (n = 95) and 4.40% (n = 101), respectively. AKI and/or MARCE were associated with systolic blood pressure (AKI: odds ratio [OR], 1.009; 95% confidence interval [CI], 1.000–1.018), hypertension (AKI: OR, 1.815; 95% CI, 1.133–2.906; MARCE: OR, 1.760;95% CI, 1.118–2.769), anterior wall infarction (AKI: OR, 1.895; 95% CI, 1.196–3.004; MARCE:OR, 1.939; 95% CI, 1.240–3.032), Killip class (AKI: OR, 1.465; 95% CI, 1.117–1.922; MARCE:OR, 1.467; 95% CI, 1.131–1.903), and serum creatinine (SCr; MARCE: OR, 1.006; 95% CI, 1.000–1.012). Hospitalization costs for patients with STEMI who developed AKI or MARCE were significantly higher than for those without AKI (9,595 ± 5,795 vs. 8,279 ± 3,872 USD, P = 0.003) or without MARCE (9,890 ± 5,616 vs. 8,255 ± 3,859 USD, P < 0.001). Conclusions In patients with STEMI undergoing pPCI with iso-osmolar contrast, the incidence of AKI and MARCE was associated with higher hospitalization costs. Systolic blood pressure, hypertension, anterior wall infarction, Killip class, and SCr were identified as risk factors for these outcomes.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

The objective of this study was to evaluate the toxicity and safety of novel Mycobacterium tuberculosis fusion strain protein derivatives,referred to as B/R strain active proteins.In cellular experiments,RAW264.7 cells were treated with each vaccine preparation,and apoptosis rates were measured.In subsequent animal experiments,C57BL/6 mice were immunized via subcutaneous injection,and their survival and body weight changes were monitored and recorded at 2,4,8,12,and 16 weeks.The lungs and spleens were harvested to calculate organ coefficients,and pathological examinations were conducted.At the eighth week of immunization,the mice were infected with high concentrations of BCG,and pathological changes in the lungs and spleens were observed 4 weeks post-infection.The apoptosis rate at 6 hours was significantly higher in the experimental group than the PBS group(P<0.05).At 12 and 24 hours,the apoptosis rate in the experimental group remained higher than that in the PBS group,although this difference was not statistically significant.After immunization,mice in all four groups exhibited normal growth patterns,as indicated by stable body weight changes.At 4 and 12 weeks post-immunization,the lung coefficients in the protein group were significantly higher than those in the PBS group at the same time points.Additionally,the lung coefficients in the BCG group were significantly elevated across all time periods(P<0.05).The spleen coefficients in the protein and BCG groups were significantly higher than those in the PBS group at 2,4,8,12,and 16 weeks,whereas the ICD B/R group showed higher spleen coefficients than the PBS group only at week 8(P<0.05).Pathological examination revealed normal lung and spleen tissues in the PBS group.However,during the 2-8 weeks immunization period,lung and spleen tissues in all experimental groups exhibited varying degrees of damage,which gradually diminished by 12-16 weeks.Notably,no tuberculosis nodules were observed in any experimental group.After infection with high concentrations of BCG,no overt pathological changes were observed on the surfaces of the lungs and spleens in any group.Microscopic examination revealed less severe pathological changes in the lungs and spleens of mice in the experimental groups than the PBS group.Furthermore,no statistically significant differences were observed between the protein group and the BCG group.Our findings suggested that the B/R strain active proteins'toxicity and safety profiles were comparable to those of BCG,and showed immunoprotective effects.This study provides an experimental foundation for the development of a novel tuberculosis vaccine.

By synthesizing the latest research achievements of AI technology in the field of surgery, as well as analyzing its technical challenges and risks, it aims to provide guidance for future innovations and clinical applications, promoting the advancement and implementation of AI in minimally invasive surgery.

Objective To investigate the therapeutic effect of Gypenoside L(Gyp-L)on diabetic retinopathy(DR)rats and its effect on the p38 mitogen-activated protein kinase(MAPK)signaling pathway.Methods Rats were divided into 6 groups(n=12):blank group,model group,low,medium,high dose group and combination group.The blank group was normal control rats,and the other groups were DR rat models.Rats in the blank group and model group were intragastrically administered with sodium carboxymethyl cellulose.Rats in the low,medium and high dose group were ga-vaged with 50,100,and 200 mg·kg-1·d-1 of Gypenoside L solution,respectively.Rats in the combination group were gavaged with 200 mg·kg-1·d-1 of Gypenoside L solution,and 2 mg·kg-1·d-1 of p38 MAPK agonist Anisomycin was in-jected into the tail vein.The rats in each group were gavaged with a volume of 2 mL per day for a total treatment period of 4 weeks.After the treatment,fundus photography was performed on the rats in each group,and retinal tissues were stained with hematoxylin and eosin(HE).Fasting blood glucose was measured using a Roche blood glucose meter,and se-rum insulin levels were measured using an ELISA kit.Retinal superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-Px),malondialdehyde(MDA),tumor necrosis factor-α(TNF-α),interleukin(IL)-1 β,and IL-6 levels were measured according to the instructions of the kit.Western blot was used to detect the protein levels of p38 MAPK,p-p38 MAPK,p65 nuclear factor-κB(NF-κB),p-p65 NF-κB,inducible nitric oxide synthase(iNOS),and cyclooxygenase(COX-2)in the retina.Results Compared with the model group,the blood glucose level was decreased,the serum insu-lin level was increased,the fundus neovascularization was reduced,the retinal damage was alleviated,the retinal SOD,CAT and GSH-Px levels were increased,the MDA level was decreased,the TNF-α,IL-1β and IL-6 levels were decreased,and the p-p38 MAPK,p-p65 NF-κB,iNOS and COX-2 protein levels were decreased in the low,medium and high dose group(all P＜0.05).Compared with the high dose group,the blood glucose level in the combination group was increased,the serum insulin level was decreased,the fundus neovascularization increased,the retinal damage was aggravated,the ret-inal SOD,CAT and GSH-Px levels were decreased,the MDA level was increased,the TNF-α,IL-1[3 and IL-6 levels were in-creased,and the p-p38 MAPK,p-p65NF-κB,iNOS and COX-2 protein levels were increased(all P＜0.05).Conclusion This study shows that Gypenoside L can reduce inflammation and oxidative stress by blocking the p38 MAPK signaling path-way,thereby playing a role in the treatment of DR.

Based on network pharmacology,molecular docking,and experimental validation,this study explored the mechanism by which Hypericum japonicum Thunb-Prunella vulgaris treat liver injury.Mice were randomly divided into four groups:a control group(CON),a model group(CCl4),a high-dose drug group(TXD-H),and a low-dose drug group(TXD-L).A mouse liver in-jury model was established using CCl4 induction.The pathological morphology of liver tissue was observed,and the serum levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)were measured.Active ingredients of traditional Chinese medicine and targets related to these medicines and diseases were obtained from databases such as TCMSP,PubChem,Swiss Tar-get Prediction,GeneCards,and DisGeNET.The intersection of these targets was used to identify potential drug targets.A network diagram illustrating the relationships between"drug-active com-ponent-intersection target"was constructed using Cytoscape.Potential targets were analyzed using the STRING database for protein-protein interaction(PPI)analysis and the DAVID database for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis.Molecular docking validation was performed using AutoDock Tools software.Subsequently,key target genes,including those related to the NLRP3 inflammasome and pyroptosis,were detected to validate the molecular docking results.Animal experimental results showed that compared to the CON group,serum AST and ALT activities in the CCl4 group mice were significantly increased(P＜0.01),while in the TXD-L group,serum AST and ALT activities were significantly decreased(P＜0.05)compared to the CCl4 group,and in the TXD-H group,AST and ALT activities were significantly decreased(P＜0.01).Through network pharmacology,135 potential targets were i-dentified,with key components found to be tetramethoxyluteolin,quercetin,kaempferol,luteolin and morin based on degree values,and key targets including TNF,SRC,AKT1,EGFR and ESR1.GO enrichment analysis yielded 304 entries,while KEGG enrichment analysis identified 91 biologi-cal pathways.Molecular docking results demonstrated strong binding between the main compo-nents of Hypericum japonicurn Thunb-Prunella vulgaris and key targets.qPCR results showed that compared to the CON group,the CCl4 group exhibited upregulated relative expression levels of SRC,EGFR,TNF-α,AKT1,and IL-18 mRNA,with significant increases in MyD88,NF-κB,IL-1β,NLRP3,Caspase-1,and ASC mRNA(P＜0.05),and significant upregulation of TLR4 and GS-DMD mRNA(P＜0.01).Compared to the CCl4 group,the TXD-H group displayed significant downregulation of EGFR,AKT1,TLR4,IL-1β,and GSDMD mRNA(P＜0.01),significant decrea-ses in TNF-α,MyD88,NF-κB,NLRP3,and ASC mRNA(P＜0.05),while SRC,IL-18,and Caspase-1 mRNA showed a downward trend.In conclusion,Hypericum japonicum Thunb-Prunel-la vulgaris exerts hepatoprotective effects through multiple components and pathways,among which inhibition of the NF-κB-NLRP3 pathway to reduce hepatocyte pyroptosis may be one of the important pathways for its protective effects.

Objective:To analyze the dynamic changes of serum exosome miR-552 and miR-653 levels in pa-tients with gastric cancer before and after chemotherapy and their relationship with clinical benefit.Methods:IA total of 128 patients with gastric cancer received chemotherapy from January 2022 to January 2024.According to the chemo-therapy effect,the two groups were divided into disease progression group and disease remission group.The levels of serum exosome miR-552 and miR-653 before and after chemotherapy were detected in the two groups,the risk fac-tors affecting the chemotherapy effect of gastric cancer patients were screened,the risk nomogram model was con-structed,and the efficacy was evaluated.Results:The proportion of TNM stage(Ⅲ+Ⅳ),lymph node metastasis,dis-tant metastasis,tumor size(>5 cm),invasion depth(T3/T4)and tumor growth pattern(invasive type)in disease progres-sion group was higher than that in disease remission group(P<0.05).The levels of serum exosomes miR-552 and miR-653 in disease progression group were higher than those in remission group before and after chemotherapy(P<0.05).Compared with before chemotherapy,miR-552 and miR-653 levels in both groups decreased(P<0.05).Logistic regres-sion analysis showed that TNM stage,lymph node metastasis,distant metastasis,tumor size,invasion depth,miR-552 and miR-653 were all risk factors affecting the chemotherapy efficacy of gastric cancer(P<0.05).ROC curve results showed that the AUC,95%CI,sensitivity and specificity of risk nomogram model to predict chemotherapy efficacy of gastric cancer were 0.867,0.672～0.991,92.80%and 80.40%,respectively(P<0.001).Calibration curve results showed that both predicted and actual predicted values were near the ideal curve,and the Hosmer-Lemeshow goodness of fit curve test χ2=1.869,P=0.782.Conclusion:The levels of serum exosomes miR-552 and miR-653 are closely related to the chemotherapy efficacy of gastric cancer,and dynamic monitoring of the above indexes is helpful for the evaluation of the disease and prognosis of gastric cancer.In this study,the risk nomogram model constructed based on the above indexes and other risk factors has high predictive value and clinical practicability for chemotherapy efficacy in patients with gastric cancer.

Objective:To investigate the relationship between the expression levels of serum microRNA(miR-138-5p)and long non-coding RNA(LncRNA)NEAT1 in patients with colorectal cancer(CRC)and clinical pathological features and prognosis.Methods:Totally 163 CRC patients admitted to our hospital from May 2019 to August 2021 were used as the CRC group,and were assigned into a survival group(n=104)and a death group(n=47)based on 3-year prognosis.Another 175 patients with benign colorectal lesions were as the control group.Real-time fluorescence quantitative PCR was used to measure serum miR-138-5p and LncRNA NEAT1.K-M curve was used to analyze the relationship between serum miR-138-5p and LncRNA NEAT1 expression and prognosis of CRC.Multivariate Cox re-gression was used to analyze the influencing factors of prognosis of CRC.ROC was used to analyze the predictive value of serum miR-138-5p and LncRNA NEAT1 for prognosis of CRC.Results:Compared with the control group,the serum miR-138-5p in the CRC group was lower(t=12.802,P<0.05),and the LncRNA NEAT1 was higher(t=13.752,P<0.05).The serum miR-138-5p was related to the differentiation degree,T stage,and N stage of CRC patients(χ2=4.780,6.557,8499,P<0.05);and the serum LncRNA NEAT1 was associated with T stage and N stage in CRC patients(χ2=8.352,9.642,P<0.05).There were obvious differences between the survival group and the death group in T stage and N stage(χ2=6.801,7.580,P<0.05),and the serum miR-138-5p in the survival group was lower than that in the death group(t=8.290,P<0.05),while the serum LncRNA NEAT1 was higher than that in the death group(t=10.008,P<0.05).K-M curve showed that patients with high miR-138-5p expression had a higher 3-year survival rate than those with low miR-138-5p expression(Log Rank χ2=6.661,P=0.010);and the 3-year survival rate of patients with high ex-pression of LncRNA NEAT1 was lower than that of patients with low expression of LncRNA NEAT1(Log Rank χ2=10.620,P=0.001).Multivariate Cox regression analysis showed that T stage(HR=3.516),N stage(HR=2.983),serum miR-138-5p(HR=0.927),and LncRNA NEAT1(HR=1.659)were all factors affecting the prognosis of CRC(P<0.05).ROC results showed that the AUC for predicting poor prognosis in CRC by combining serum miR-138-5p and LncRNA NEAT1 was 0.716,which was obviously higher than that predicted by miR-138-5p(Z=3.173,P=0.002)and LncRNA NEAT1(Z=3.253,P=0.001)alone.Conclusion:Serum miR-138-5p is lower and LncRNA NEAT1 is higher in CRC pa-tients.Moreover,the levels of both are closely related to the clinical pathological features and prognosis.
