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.

Objective:To explore the expression regulation of lipid metabolism gene ABHD5 in testes.Methods:Differential gene analysis was performed by integrating databases of TCGA and GTEx to identify the target gene ABHD5.The expression trends of ABHD5 gene in testicular carcinoma tissue were analyzed.Human testis single-cell atlases were obtained from the Human Protein Atlas and Male Health Atlas databases to determine the expression distribution of ABHD5 across different testicular cell types.Additionally,the GTEx database was utilized to visualize the expression pattern of ABHD5 in the testis,thereby enhancing the understanding of its transcriptional profile.The relationship between ABHD5 expression and age was assessed through integrated database analysis.Western blotting and immunofluorescence were performed to detect differential expressions of ABHD5 in testicular tissues of young and aged mice respectively.Results:The TCGA database indicated that the expression of ABHD5 in human testicular carcinoma tissue was significantly lower than that in normal testicular tissue which showed a negative correlation with patient survival.ABHD5 was highly ex-pressed in germ cells of the testis reveaked from Human Protein Atlas and Male Health Atlas databases.The stability of ABHD5 protein was crucial for testicular tissue,and its expression decreased with age.Furthermore,Western blot and immunofluorescence staining demonstrated that ABHD5 expression in the testicular tissue of aged mice was significantly lower than that in young mice.Conclu-sion:ABHD5 plays an important role in testicular tissue,and may be inseparable from testicular tumors and reproductive aging.How-ever,its mechanism of action remains to be further studied.

OBJECTIVE: Pneumoconiosis, a lung disease caused by irreversible fibrosis, represents a significant public health burden. This study investigates the causal relationships between gut microbiota, gene methylation, gene expression, protein levels, and pneumoconiosis using a multi-omics approach and Mendelian randomization (MR). METHODS: We analyzed gut microbiota data from MiBioGen and Esteban et al. to assess their potential causal effects on pneumoconiosis subtypes (asbestosis, silicosis, and inorganic pneumoconiosis) using conventional and summary-data-based MR (SMR). Gene methylation and expression data from Genotype-Tissue Expression and eQTLGen, along with protein level data from deCODE and UK Biobank Pharma Proteomics Project, were examined in relation to pneumoconiosis data from FinnGen. To validate our findings, we assessed self-measured gut flora from a pneumoconiosis cohort and performed fine mapping, drug prediction, molecular docking, and Phenome-Wide Association Studies to explore relevant phenotypes of key genes. RESULTS: Three core gut microorganisms were identified: Romboutsia ( OR = 0.249) as a protective factor against silicosis, Pasteurellaceae ( OR = 3.207) and Haemophilus parainfluenzae ( OR = 2.343) as risk factors for inorganic pneumoconiosis. Additionally, mapping and quantitative trait loci analyses revealed that the genes VIM, STX8, and MIF were significantly associated with pneumoconiosis risk. CONCLUSIONS This multi-omics study highlights the associations between gut microbiota and key genes ( VIM, STX8, MIF) with pneumoconiosis, offering insights into potential therapeutic targets and personalized treatment strategies.

Objective: To compare the long-term clinical and radiographic outcomes of transforaminal endoscopic lumbar discectomy (TELD) versus microdiscectomy (MD). Methods: The data of 154 patients with lumbar disc herniation (LDH) who underwent TELD (n = 89) or MD (n = 65) were retrospectively analyzed. The patients’ clinical outcomes were evaluated using visual analogue scales for leg and low back pain, the Japanese Orthopaedic Association (JOA) score, and the Oswestry Disability Index (ODI). The evolution of radiographic manifestations was observed during follow-up. Potential risk factors for a poor clinical outcome were investigated. Results: During a mean follow-up of 5.5 years (range, 5–7 years), the recurrence rate was 4.49% in the TELD group and 1.54% in the MD group. All scores significantly improved from preoperatively to postoperatively in both groups (p < 0.01). The improvement in the ODI and JOA scores was significantly greater in the TELD than MD group (p < 0.05). Forty-seven patients (52.8%) in the TELD group and 32 (49.2%) in the MD group had Modic changes before surgery, most of which showed no changes at the last follow-up. The degeneration grades of 292 discs (71.0%) were unchanged at the last follow-up, while 86 (20.9%) showed improvement, mostly at the upper adjacent segment. No significant difference was observed in the intervertebral height index or paraspinal muscle-disc ratio. Conclusion Both TELD and MD provide generally satisfactory long-term clinical outcomes for patients with LDH. TELD can be used as a reliable alternative to MD with less surgical trauma. Modic type II changes, decreased preoperative intervertebral height, and a high body mass index are predictors of a poor prognosis.

Objective A preliminary study of the safety and efficacy of the Pipeline embolization device(PED)for the treatment of vertebral artery dissecting aneurysm(VADA).Methods Clinical data of 21 patients with VADA treated with PED in the Department of Neurosurgery of the First Affiliated Hospital of Xinjiang Medical University from January 2019 to June 2023 were retrospectively collected,and the surgical approach,perioperative complications,and imaging results were recorded and followed up.Patients'prognosis was assessed by modified Rankin Scale score(mRS),and Kamran grading was used for imaging follow-up.Results Of the 21 patients,17 had unruptured aneurysms and 4 had ruptured aneurysms.A total of 22 PEDs were placed,of which 13 patients underwent PED placement alone and 8 patients underwent PED combined with coil embolization,with a technical success rate of 100% .Three patients with ruptured aneurysms had combined stenosis proximal to the aneurysm,and 1 patient with>50% stenosis received an additional Solitaire stent for in-stent posterior dilatation.Immediate postoperative Kamran grading was grade 1 in 16 patients,grade 2 in 1 patient,and grade 3 in 4 patients.There were 2 perioperative complications,including postoperative aneurysm rupture in 1 patient and severe pulmonary infection in 1 patient who eventually died.At the time of discharge,15 patients had an mRS score of 1,2 patients had a score of 2,1 patient had a score of 3,1 patient had a score of 4,and 2 patient had a score of 6.Eighteen patients were followed up with a median follow-up time of 12.5(6-30)months,of which 13 patients had an mRS score of 0,4 patients had a score of 1,and 1 patient had a score of 2.There were 2 patients with a Kamran grade of 2,4 patients with a grade of 3,and 12 patients with a grade of 4.Conclusion The surgical success rate and safety of VADA treatment with PED is high,but perioperative complications and postoperative care should not be ignored either and a large number of samples are still needed for further study in the future.

Porcine circovirus type 2(PCV2)mainly damages the immune cells of pigs,causing lym-phocyte depletion and immune suppression.Interleukin(IL)-15 regulates immune functions wide-ly,and plays an important regulatory role in the survival,proliferation,differentiation and immune function of a variety of immune cells such as natural killer(NK),CD8+T cells and NKT cells.In this study,in order to determine the effect of PCV2 on IL-15 expression,4-week-old piglets(n=4)were infected with PCV2 and the negative control group(n=4)was set up.On day 7 post-infec-tion,the inguinal lymph nodes of the infected and control groups were collected,and porcine cyto-kine antibody microarray(QAP-CYT-1)was employed to quantify the expression of cytokines in the tissues,screen for differential cytokines,and GO and KEGG enrichment analysis for IL-15 were conducted.Real-time quantitative fluorescent PCR(qPCR)and ELISA were used to verify the level of IL-15 mRNA and protein,and those in porcine peripheral blood mononuclear cells(PBMC)and serum were simultaneously detected.Compared with the negative control group,the expression lev-el of IL-15 was significantly reduced in the infected group(P＜0.05);IL-15 was mainly involved in cytokine-cytokine receptor interactions,immune responses,cellular activation,and the regulation of JAK-STAT and TNF signaling pathways.The levels of IL-15 mRNA and protein in inguinal lymph nodes in the infected group were significantly lower than those in the control group(P＜0.05),which was consistent with the detection results of QAP-CYT-1.However,there was no significant difference in IL-15 mRNA and protein levels in PBMC and serum.These results indicate that PCV2 can inhibit IL-15 in the inguinal lymph node microenvironment of piglets.This study can provide important information for further revealing the immunosuppressive mechanism of PCV2.

Objective:To investigate the clinical significance of TP53 allelic state in patients with myelodysplastic syndromes(MDS).Methods:The clinical data of 858 MDS patients who underwent second-generation sequencing(NGS)testing in the First Affiliated Hospital of Soochow University from January 2019 to December 2021 were retrospectively analyzed.Results:The median age of the patients was 52 years old,and median follow-up time was 23.8(0.4-109.6)months.Four hundred and one patients(46.7％)had at least one chromosomal abnormality,including 106 complex karyotypes and 78 monosomal karyotypes.A total of 103 cases of TP53 mutations were identified,with a mutation rate of 12％.Compared with TP53 wild-type,various types of chromosomal abnormalities were significantly more common in patients with TP53 mutations(all P＜0.001).Patients with TP53 mutations had lower hemoglobin levels,lower platelet counts and higher percentage of bone marrow primitive cell compared with TP53 wild type(all P＜0.05),and significantly shorter overall survival(OS).Among 97 evaluable patients,33 cases(34％)were mono-allelic TP53 mutation,while 64 cases were bi-allelic TP53 mutation.Patients in bi-allelic TP53 mutation subgroup had a higher proportion of chromosomal abnormalities and a lower number of co-mutations compared with mono-allelic TP53 mutation.The median OS was 33.6 months in patients with mono-allelic state and only 11.4 months in patients with bi-allelic state(HR=2.138,95％CI:1.053-4.343,P＞0.05).Median OS was not reached in TP53 wild-type patients,and there was a significant difference in OS among TP53 wild-type,mono-allelic and bi-allelic TP53 mutation patients(P＜0.001).Multivariable Cox regression analysis showed that bi-allelic TP53 was an independent predictor of poor outcomes(HR=2.808,95％CI:1.487-5.003,P=0.001),while mono-allelic TP53 mutation and wild-type TP53 were not.Conclusion:Patients with TP53 mutations have a poor prognosis,and bi-allelic TP53 mutations have a worse prognosis compared with mono-allelic TP53 mutations and independently affect the prognosis of MDS patients.
