Objective: To analyze the unregistered treatment situation and its influencing factors among pulmonary tuberculosis patients in Quzhou City, Zhejiang Province from 2017 to 2023, so as to provide a basis for promoting the management of tuberculosis patients and optimizing disease prevention and control strategies. Methods: Data of pulmonary tuberculosis patients including demographic information, etiological results, and mortality status were collected through the China Disease Prevention and Control Information System Infectious Disease Reporting and Surveillance System and the Tuberculosis Management Information System. Pulmonary tuberculosis patients not matched in the Tuberculosis Management Information System were defined as unregistered treatment patients, and the unregistered treatment rate was analyzed. Factors affecting unregistered treatment among pulmonary tuberculosis patients were analyzed using a multivariable logistic regression model. Results: A total of 10 779 pulmonary tuberculosis patients were reported in Quzhou City from 2017 to 2023, including 7 700 males (71.44%) and 3 079 females (28.56%). There were 5 484 cases aged <65 years, accounting for 50.88%. Among them, 630 cases were unregistered treatment, with an unregistered treatment rate of 5.84% (95%CI: 5.42%-6.38%). Multivariable logistic regression analysis showed pulmonary tuberculosis patients aged ≥65 years (OR=1.829, 95%CI: 1.512-2.212) had a higher risk of being unregistered treatment than those aged <65 years; patients with non-local household registration (OR=5.710, 95%CI: 4.724-6.901) had a higher risk than local patients; and patients engaged in housework/unemployed (OR=2.001, 95%CI: 1.421-2.818) or other occupations (OR=2.396, 95%CI: 1.789-3.137) had a higher risk than farmers. The mortality of unregistered treatment pulmonary tuberculosis patients was higher than the registered treatment patients (26.67% vs. 5.02%),with a significantly elevated mortality risk (OR=7.147, 95%CI: 5.738-8.902). Conclusions The unregistered treatment rate among pulmonary tuberculosis patients was well controlled in Quzhou City from 2017 to 2023, but the elderly, patients with non-local household registration, and those engaged in housework/unemployed had a higher risk of unregistered treatment. It is recommended to improve medical and social security policies, strengthen health education on tuberculosis prevention, enhance treatment adherence, and reduce mortality risk.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and memory loss, with few effective treatments currently available. The multifactorial nature of AD, shaped by genetic, environmental, and biological factors, complicates both research and clinical management. Recent advances in artificial intelligence (AI) and multi-omics technologies provide new opportunities to elucidate the molecular mechanisms of AD and identify early biomarkers for diagnosis and prognosis. AI-driven approaches such as machine learning, deep learning, and network-based models have enabled the integration of large-scale genomic, transcriptomic, proteomic, metabolomic, and microbiomic datasets. These efforts have facilitated the discovery of novel molecular signatures and therapeutic targets. Methods including deep belief networks and joint deep semi-non-negative matrix factorization have contributed to improvements in disease classification and patient stratification. However, ongoing challenges remain. These include data heterogeneity, limited interpretability of complex models, a lack of large and diverse datasets, and insufficient clinical validation. The absence of standardized multi-omics data processing methods further restricts progress. This review systematically summarizes recent advances in AI-driven multi-omics research in AD, highlighting achievements in early diagnosis and biomarker discovery while discussing limitations and future directions needed to advance these approaches toward clinical application.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective To explore the characteristics of fluid flow within loaded osteons under different boundary conditions.Methods The COMSOL Multiphysics software was used to establish a three-dimensional(3D)finite element model of osteons with different boundary conditions,and the variation rules of pore pressure and flow velocity of osteons under different inner wall pulsating blood pressures and outer wall elastic constraint conditions were analyzed.Results As the pulsatile blood pressure inside the osteon increased from 0 mmHg(1 mmHg=0.133 kPa)to 300 mmHg,the peak pore pressure within the osteon correspondingly increased from 26 kPa to 68 kPa.As the elastic constraint on the outer wall of osteons changed from being completely elastic to completely constrained,the peak pore pressure within osteons increased from 15 kPa to 26 kPa,and the peak flow velocity increased from 0.04 um/s to 0.07 um/s.Conclusions This study reveals the influence laws of changes in boundary conditions such as the pulsatile blood pressure on the inner wall and the elastic constraint on the outer wall of osteons on fluid flow characteristics within loaded osteons.These findings are conducive to a deeper understanding of the mechanical response mechanisms of bone tissues in both physiological and pathological states,and provide an important theoretical basrs for further researches on bone mechanotransduction.

Objective To explore the effects of preoperative transcatheter arterial chemoembolization(TACE)on early postoperative recurrence in the China liver cancer(CNLC)staging Ⅰb-Ⅱa patients with primary hepatocellular carcinoma.Methods The data of patients with CNLC Ⅰb-Ⅱa stage hepatocellular carcinoma who underwent curative liver resection in Xiangyang Central Hospital from May 2017 to May 2022 were retrospectively analyzed.A total of 76 patients were included,patients were divided into preoperative TACE group(n=32)and surgery group(n=44)according to whether they underwent preoperative TACE.Observe the postoperative recovery of patients.Combined with the postoperative pathological results,adjuvant TACE treatment is performed.Regular reexamination and follow-up are conducted after discharge.The Kaplan-Meier method was used to estimate survival time,calculate 95％CI,and plot the Disease-free(DFS)survival curve.The Cox proportional risk model was used for univariate and multivariate analysis.Results The 1-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(96.9％vs.84.1％,P＞0.05).The 2-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(90.6％vs.70.5％,P＜0.05).The disease-free survival of the preoperative TACE group was higher than the direct surgery group(23.03 months vs.20.14 months,P＜0.05).The incidence of treatment-related adverse events after surgery in the preoperative TACE group was higher than that in the direct surgery group(34.4％vs.20.5％,P＞0.05).Multivariate Cox regression analysis showed that different treatment methods,tumor number ≥ 2,and tumor microvascular invasion were prognostic factors affecting tumor recurrence.No severe adverse reactions occurred in either group,and no deaths caused by adverse reactions were observed.Conclusion Compared with direct surgery,preoperative TACE can help improve early postoperative recurrence,prolong patients'disease-free survival,and do not lead to serious adverse events.

Objective To explore the clinical application effects of Chen's pancreatojejunostomy in laparoscopic pancreaticoduodenectomy.Methods Clinical data of 176 patients who underwent laparoscopic pancreaticoduodenectomy in Xiangyang Central Hospital from January 2019 to December 2024 were retrospectively analyzed.According to the methods of intraoperative pancreatojejunostomy,the patients were divided into two groups,the research group(102 cases)using Chen's pancreatojejunostomy,and the control group(74 cases)using duct-to-mucosa pancreatojejunostomy.The two groups were compared on clinical indicators,including operation time,pancreatojejunostomy time,intraoperative blood loss,incidence of postoperative complications,length of hospital stay,and 30-day postoperative mortality rate.Results All 176 patients successfully underwent laparoscopic pancreaticoduodenectomy.There were no statistically significant differences between the two groups in intraoperative blood loss,biochemical leakage,abdominal bleeding,upper gastrointestinal bleeding,delayed gastric emptying,bile leakage,abdominal infection,and 30-day postoperative mortality rate(P＞0.05).The pancreatojejunostomy time[(22.33±5.95)min]and operation time[(334.60±66.42)min]in the study group were significantly shorter than those in the control group[(30.70±5.50)min]and[(414.46±60.96)min],with statistically significant differences(P＜0.05).Two groups of patients did not develop grade C pancreatic fistula.The incidence of grade B pancreatic fistula in the study group(5.88％)was significantly lower compared to the control group(16.22％),and this difference was statistically significant(P＜0.05).Additionally,The postoperative hospital stay of the study group patients[(17.10±6.89)days]was significantly shorter than in the control group[(20.88±8.40)days],with a statistically significant difference(P＜0.05).Conclusion Chen's pancreatojejunostomy is a feasible,safe,and effective procedure in laparoscopic pancreaticoduodenectomy,which can shorten the pancreatojejunostomy time,reduce the incidence of postoperative pancreatic fistula,and decrease the length of hospital stay.

Objective To investigate the clinical efficacy of wrapping the hepatic artery with the hepatogastric ligament for preventing bleeding of the hepatic artery and its branches following pancreaticoduodenectomy(PD).Methods 194 patients who underwent PD in Xiangyang Central Hospital from January 2017 to November 2024 were enrolled and categorized into two groups based on whether the hepatic artery was enwrapped with the hepatogastric ligament during the operation.The wrapped group consisted of 95 cases where the hepatic artery was wrapped,while the non-wrapped group had 99 cases without such wrapping.Intraoperative parameters(intraoperative blood loss and operative time)and postoperative complications(pancreatic fistula,abdominal cavity infection,biliary fistula,delayed gastric emptying,postoperative bleeding,and bleeding of the hepatic artery and its branches)were compared between the two cohorts.Univariate and multivariate Logistic regression analyses were conducted to identify the independent risk factors for postoperative bleeding.Results PD was accomplished successfully in both groups.There was no remarkable difference in intraoperative indices like blood loss and operative time between the two groups(P＞0.05).Similarly,no significant disparities were noted in postoperative complications such as pancreatic fistula,abdominal infection,biliary fistula,and delayed gastric emptying(P＞0.05).Nevertheless,the incidence of postoperative bleeding in the wrapped group was lower than that in the non-wrapped group(3.16％vs.12.12％,P=0.019),and the incidence of bleeding of the hepatic artery and its branches after surgery was also significantly decreased in the wrapped group(0 vs.10.10％,P=0.004).Logistic regression analysis revealed that the operation time(OR=1.013,P=0.011),pancreatic fistula(OR=9.006,P=0.006)and celiac infection(OR=7.930,P=0.014)are independent risk factors of postoperative bleeding,Hepatogastric ligament encapsulation of hepatic artery was an independent protective factor for postoperative hemorrhage of PD(OR=0.084,P=0.006).Conclusion Wrapping the hepatic artery with the hepatogastric ligament reduces PD postoperative bleeding,especially that of the hepatic artery and its branches,without adding other complications.
