Pancreatic cancer is a highly malignant solid tumor of the digestive system with extremely poor treatment prognosis. Although its incidence rate is low， its mortality rate is extremely high. In recent years， the number of diagnosed cases worldwide has continued to rise， making pancreatic cancer the sixth leading cause of cancer-related deaths globally. Currently， clinical treatment primarily relies on operation and chemotherapy to suppress tumors. However， these approaches face challenges such as suboptimal efficacy， high postoperative recurrence rates， and severe adverse reactions. Therefore， identifying safe and effective treatment modalities remains a pressing challenge for the medical community. In recent years， research on traditional Chinese medicine （TCM） interventions for pancreatic cancer has increased significantly. Multiple studies have shown that single-herb TCM， TCM formulas， and their derived single compounds can regulate the levels of tumor cell signaling pathways through multiple action targets. They inhibit the development and progression of pancreatic cancer by inhibiting cancer cell proliferation， promoting cell apoptosis， inhibiting tumor angiogenesis， reducing cancer cell invasion and migration capabilities， regulating the cell cycle， and modulating the tumor microenvironment. Additionally， TCM has the advantages of significantly enhancing the anticancer efficacy of chemotherapy drugs and causing fewer adverse reactions. However， the specific action mechanisms by which TCM intervenes in pancreatic cancer remain unclear. Further extensive research is still needed to validate the role of regulating classical signaling pathways such as phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， Wnt/β-catenin， nuclear transcription factor-κB （NF-κB）， notch， and hedgehog in the treatment of pancreatic cancer. Therefore， this paper reviewed Chinese and international studies on TCM intervention in pancreatic cancer through relevant signaling pathways in recent years， summarized the potential action mechanisms of TCM in the treatment of pancreatic cancer， and provided references for related research in the future.

Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

Obesity， a global chronic disease， is associated with adipose tissue dysfunction， which is one of the contributing factors to obesity. The cyclic adenosine monophosphate （cAMP） signaling pathway， a key regulator of lipid metabolism， plays a pivotal role in obesity development. Various of traditional Chinese medicine monomers， such as flavonoids， lignans， phenols， and terpenoids， as well as traditional Chinese medicine compound formulas like Xiaoyao powder， Shengmai powder， and Zexie decoction， can maintain energy homeostasis， balance adipose tissue function， regulate glucose metabolism， improve insulin resistance， and suppress inflammatory responses through cAMP signaling pathway regulation， thereby intervening in lipid metabolism for obesity treatment. Although a substantial amount of basic research has preliminarily elucidated the potential mechanisms by which traditional Chinese medicine intervenes in obesity through the cAMP signaling pathway， clinical translational research remains inadequate. There is an urgent need for large-sample， high-quality randomized controlled trials to validate these findings.

Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

With the rapid global population aging, multimorbidity is becoming a more serious public health problem, to which medical researchers have paid close attention. A standardized definition of multimorbidity is essential for relevant research. However, there is a lack of consensus on the definition of multimorbidity, which makes it difficult to compare results among studies and replicate important findings. Based on the conceptual comparison, this paper summarizes the key dimensions of the definition of multimorbidity, including the number and types of conditions, the granularity of classification, methods for obtaining outcomes, and settings and objectives of research. It also discusses the inherent relationships among the dimensions and their impact on research results, and introduces the characteristics of the commonly used condition lists in current multimorbidity definition research. By suggesting areas for improvement in the multimorbidity definition system, it aims to enhance the understanding of multimorbidity research and achieve consensus on the definition, thereby facilitating further multimorbidity research.

AIM:To investigate the therapeutic effects and potential mechanism of pachymic acid(PA)on li-popolysaccharide(LPS)-induced acute kidney injury(AKI)in mice.METHODS:(1)Genes related to AKI were screened using the DAVID database.Core genes were identified by intersecting related genes and analyzed using Cyto-scape software.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were performed through the DAVID database for the cross-targets.Molecular docking and activity assays were conducted on the primary core targets.(2)A total of 100 C57BL/6J mice were randomly divided into five groups:normal control(NC),model(LPS),solvent control(LPS+DMSO),and treatment groups(LPS+PA-10 and LPS+PA-20),with 20 mice in each group.The LPS-AKI model was established by intraperitoneal injection of 18 mg/kg LPS.The treatment groups received 10 mg/kg and 20 mg/kg PA,respectively,and the solvent control group was administered an equivalent dose of DMSO.Mice were euthanized 24 h after injection.Serum was collected for biochemical analysis,and Western blot was used to detect neutro-phil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),caspase-3,cleaved caspase-3,interleu-kin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1)protein expression.RT-qPCR was employed to detect inflammatory factor mRNA levels.Molecular docking was used to simulate the optimal binding site of PA to caspase-3.En-zyme activity assays were performed to assess caspase protein activity,and renal lesions were observed via hematoxylin and eosin(HE)staining.Apoptosis was detected by TUNEL staining.RESULTS:(1)Thirty-one potential targets of PA against AKI were identified through network pharmacology.GO and KEGG enrichment analyses indicated that these tar-gets were primarily involved in immune response,inflammatory processes,apoptosis and survival,angiogenesis and hemo-dynamics,oxidative stress,and endoplasmic reticulum stress.Key targets included CASP3(caspase-3),PTGS2,BCL2,CCL2,and CYP219.(2)PA treatment improved renal function and reduced tubular epithelial injury.It significantly de-creased NGAL,KIM-1,and cleaved caspase-3 protein levels,as well as inflammatory factors TNF-α,IL-1β,and MCP-1 mRNA and protein expression.PA also reduced apoptosis of renal tubular epithelial cells.Enzyme activity assays and mo-lecular docking revealed that PA exerted its anti-apoptotic effect by directly binding to caspase-3,thereby inhibiting its ac-tivation by caspase-8.CONCLUSION:PA demonstrated a therapeutic effect in LPS-AKI,potentially through the inhibi-tion of inflammatory factor synthesis and release,as well as the inhibition of caspase-3 activation by caspase-8,reducing apoptosis in renal tubular epithelial cells.

Objective:To investigate the prognostic value and safety of thoracic radiotherapy in patients with synchronous oligometastatic, driver gene-negative non-small cell lung cancer (NSCLC) receiving immune checkpoint inhibitors (ICIs) as first-line treatment.Methods:Data were retrospectively collected from 55 patients diagnosed with synchronous oligometastatic, driver gene-negative NSCLC who received first-line ICIs from January 2017 to March 2022. These patients were categorized into two groups based on the administration of thoracic radiotherapy: the thoracic radiotherapy group ( n = 27) and the non-thoracic radiotherapy group ( n = 28). Comparative analyses were conducted to evaluate survival outcomes and safety profiles between the two groups. Results:Among the 55 patients, 27 (49.1%) received thoracic radiotherapy. The median follow-up time was 37.0 months (2.2-76.7 months). Patients in the thoracic radiotherapy group exhibited significantly improved median overall survival (OS: 53.4 vs. 21.3 months, P = 0.049) and median progression-free survival (PFS: 13.6 vs. 8.3 months, χ2=4.11, P = 0.043) compared to those in the non-thoracic radiotherapy group. Multivariate Cox regression analysis identified thoracic radiotherapy as an independent prognostic factor for OS ( HR = 0.39, 95% CI: 0.17-0.90, P = 0.027) and PFS ( HR = 0.53, 95% CI: 0.28-0.99, P = 0.046). The most common grade 3 or higher toxicity was bone marrow suppression, occurring in seven patients (12.7%). There was no significant difference between both groups in the incidence of grade 3 or higher treatment-related adverse events, including pneumonitis. Conclusion:In patients with driver gene-negative, synchronous oligometastatic NSCLC, first-line immunotherapy combined with thoracic radiotherapy may improve survival outcomes without increasing the incidence of severe treatment-related adverse events. Further large-scale, randomized prospective trials are needed to verify the findings of this study.

Objective To explore the clinical characteristics as well as molecular epidemiological features of resis-tance genes and virulence genes of carbapenem-resistant Klebsiella pneumoniae(CRKP)infection in a region,and provide scientific basis for the prevention,treatment,and epidemiological study of CRKP.Methods 60 non-repeti-tive CRKP strains isolated clinically from Puyang Oilfield General Hospital from November 2023 to September 2024 were analyzed retrospectively.Antimicrobial susceptibility testing was performed using VITEK 2 Compact automa-tic microbial analyzer,K-B disk diffusion method,and micro-broth dilution method.Mucus phenotype of bacterial strains was identified by string test.Carbapenemase was detected by carbapenemase inhibitor enhancement assay.Molecular features,such as multi-locus sequence typing(MLST),capsule serotypes,resistance genes,virulence genes,plasmid replication types of strains,as well as the genetic and evolutionary relationships of strains were de-termined by whole genome sequencing and bioinformatics analysis.Results CRKP strains were mainly isolated from elderly male hospitalized patients.Specimens were mostly from sputum(71.67％),mainly distributed in depart-ment of respiratory medicine(30.00％).All strains were highly resistant to multiple commonly used antimicrobial agents,only with high susceptibility rates to cefotaxime/avibactam,tigecycline,and polymyxin B(＞60.00％).Two CRKP strains were positive for string test.95.00％of the strains produced class A serine carbapenemase.All strains carried fluoroquinolone,phosphomycin,β-lactam,and aminoglycoside resistance genes;enterobactin,Esche-richia coli common pilus(ECP),and outer membrane protein-related virulence genes;as well as plasmids from the IncF plasmid family.Carbapenemase gene was mainly blaKPC-2(95.00％),and the major capsule serotype was KL19(43.33％).In MLST,ST11(51.67％)was the dominant clone group,and ST11-KL62(n=12)was the dominant subtype.Conclusion CRKP in this hospital is highly resistant to multiple commonly used antimicrobial agents,and its mechanism of resistance to carbapenems is mainly related to the presence of blaKPC-2 resistance gene.All strains have coexisting multiple resistance genes and virulence genes,and show a phenomenon of multi-clone transmission.ST11 is the dominant clone group,and ST11-KL62 is the main prevalent subclone type.
