With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

ObjectiveTo investigate the effect of Sanet Vision Integrator (SVI)-based visuomotor integration training on the severity of neglect symptoms, upper limb motor function and activities of daily living (ADL) in patients with post-stroke unilateral spatial neglect (USN). MethodsFrom July, 2023 to September, 2025, 41 patients with post-stroke USN in Beijing Bo'ai Hospital were enrolled and randomly assigned to control group (n = 20) and experimental group (n = 21). Both groups received conventional rehabilitation and visual scanning training, while the experimental group received supplementary SVI-based visuomotor integration training, including saccadic, rotation and hand-eye coordination training, for eight weeks. They were assessed with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, all the scores significantly improved in both groups (|t| > 4.004, P < 0.001), and the total scores of CBIT-HK and the core visual search sub-items (star cancellation, line crossing and letter cancellation), FMA-UE and MBI were better in the experimental group than in the control group (t > 2.096, P < 0.05). ConclusionSVI-based visuomotor training can effectively alleviate the USN symptoms, broaden the span of visual attention, facilitate the functional recovery of the affected upper extremity, and improve ADL in patients after stroke.

To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.

Objective To observe the origin and course of the obturator artery(OA),so as to provide anatomical reference for reducing hemorrhage during pelvic surgery and pubic fracture fixation.Methods A total of 65 human hemi-pelvises specimens with intact structure were dissected to observe the origin,course and other variations of OA.Measure the length of the inner section of OA basin and the outer diameter at the origin,etc.Results OA originated from the internal iliac artery in 57 cases(87.7%),including 3 cases(4.6%)of the superior gluteal artery,5 cases(7.7%)of the inferior gluteal artery,3 cases(4.6%)of the external iliac artery and 5 cases(7.7%)of the inferior epigastric artery.OA participated in the formation of the arterial trunk in 3 cases(4.6%).The length of the pelvic segment of the OA in male and female was(50.87±15.41)mm and(51.71±14.19)mm,respectively,with no statistically significant difference between them(P>0.05).The outer diameters at the origin of the OA in male and female were(2.79±1.05)mm and(2.35±0.86)mm,and there was no statistically significant difference between them(P>0.05).Conclusion OA mainly originated from the anterior trunk of the internal iliac artery,with a few OA originated from the branches of the posterior trunk or the inferior epigastric artery,or participated in the formation of the arterial trunk.In pelvic surgery involving OA area,attention should be paid to the length of its pelvic segment and the outer diameter at the origin of OA,so as to better locate and protect blood vessels during surgery.

Inflammatory response,immunosuppression,and drug sensitivity have been reported to have a significant correlation with the disulfidptosis levels in cancer patients.However,the value of disulfidpto-sis in colorectal cancer therapy remains unclear.Therefore,we classified the CRC cells into different cell types using single-cell sequencing data and cell-specific markers and analyzed their relationship with the cell disulfidptosis level.We found that the high disulfidptosis regions were concentrated in epithelial-like CRC cells.Further exploration using the disulfidptosis and programmed cell death 1 inhibitor therapy treated differential expression genes indicated that CRC patients with high disulfidptosis levels exhibited a lower risk profile and increased sensitivity to immunotherapy.By using the spatial transcriptomic analy-sis,we found that ubiquinol-cytochrome c reductase core protein 1(UQCRC1),a disulfidptosis-related gene,is highly expressed in epithelial-like CRC cells and co-localized with immune-infiltrated tumor re-gions.Additional bioinformatic analyses and experimental validation further confirmed that UQCRC1 was downregulated in CRC tissues.Overexpression of UQCRC1 suppressed CRC cell proliferation and migra-tion.These findings indicate that UQCRC1 is a potential target for CRC diagnosis and treatment.

This case report describes the diagnostic and therapeutic management of a 67-year-old fe-male with a 40-year history of Sj?gren disease(SjD)who was hospitalized for evaluation of recurrent fever lasting over one month.The patient's initial diagnosis of SjD was established four decades earlier based on clinical manifestations,serological findings,and evidence of glandular damage.Her clinical presenta-tion included recurrent parotid gland enlargement accompanied by sicca symptoms,notably persistent xerostomia and xerophthalmia,followed by progressive dental caries.Serological studies demonstrated positivity for antinuclear antibodies,anti-SSA/Ro,and anti-α-fodrin antibodies.Objective assessments confirmed significant ocular involvement(Schirmer's test≤5 mm/5 min)and pulmonary interstitial changes on chest CT,consistent with the 2016 American College of Rheumatology and European League Against Rheumatism(ACR/EULAR)classification criteria for SjD.The patient's condition remained sta-ble under low-dose corticosteroids and disease-modifying anti-rheumatic drugs(DMARDs)until the re-cent onset of prolonged fever,necessitating evaluation for fever of unknown origin.Differential diagnoses considered disease flare,infection,and malignancy.The European Sj?gren's Syndrome Disease Activity Index(ESSDAI)score was 5 points,indicating moderate systemic disease activity.Initial laboratory in-vestigations revealed no evidence of infection,and empirical anti-infective therapy proved ineffective.No-tably,despite the absence of lymphadenopathy,laboratory findings including borderline positive IgM λ M-protein,elevated lactate dehydrogenase,hyperferritinemia,and increased β2-microglobulin levels raised suspicion for lymphoproliferative disorders,given the established association between SjD and lymphoma.Bone marrow aspiration showed no significant abnormalities,but PET/CT imaging detected hypermetabolic lesions in the left breast and right distal femur,suggesting potential malignancy.Subse-quent histopathological examination of the breast lesion confirmed non-Hodgkin's lymphoma(NHL),specifically diffuse large B-cell lymphoma(DLBCL)of the germinal center B-cell(GCB)subtype.Treatment with R-CHOP chemotherapy(rituximab,cyclophosphamide,doxorubicin,vincristine,and prednisone)induced complete metabolic remission after three cycles.However,she subsequently developed treatment-related complications,including myelosuppression and pulmonary infection.This case underscores the importance of maintaining a high index of suspicion for atypical site involvement in SjD patients,particularly when lymphoma risk factors are present.Comprehensive differential diagnosis should include lymphoma and other malignancies,and the diagnostic value of PET/CT and histopatholog-ical examination in disease evaluation is emphasized.SjD complicated by breast lymphoma is exceptional-ly rare,and its pathogenesis may involve lymphocytic infiltration,abnormal activation of lymphocytes,formation of ectopic germinal centers in the breast,and eventual malignant transformation.These mecha-nisms require further investigation through clinical and basic research studies.

Objective To analyze the impact of the National Centralized Drug Procurement Policy(hereinafter referred to as the"centralized procurement policy")on the utilization of breast cancer treatment drugs in a specialized cancer hospital.Methods The defined daily dose(DDD)method was used to compare the daily drug cost(DDC),drug utilization frequency(DDDs),and affordability of letrozole,anastrozole,and capecitabine before and after the implementation of the centralized pro-curement policy in a tertiary specialized cancer hospital in Guangzhou.Results and Conclusion After the policy implementa-tion,the DDC of all three drugs decreased.The out-of-pocket DDC for the selected drugs remained stable or decreased,while the out-of-pocket DDC for both originator drugs and generic drugs increased,with a more pronounced increase for originator drugs.The proportion of DDDs for the selected drugs increased post-policy.The centralized procurement policy not only reduced the prices of selected drugs but also drove down the prices of generic and originator drugs.It is recommended to further expand the scope of centralized procurement for anticancer drugs and the types of cancers covered,as well as to establish a transitional mech-anism for medical insurance payment standards.

Objective:To investigate the temporal correlation between occupational stress and elevated blood pressure among petroleum workers in Xinjiang.Methods:Based on the Occupational Health Study Cohort of Petroleum Workers (OHSPIW), 1600 petroleum workers in Xinjiang who underwent occupational health examinations from May to June 2015 and December 2017 were selected as the research subjects. The occupational stress of workers was evaluated using the Occupational Roles Questionnaire (ORQ) in the Occupational Stress Inventory-Revised (OSI-R). The blood pressure measurement data of physical examination results were collected. The relationship between the ORQ total score and blood pressure was analyzed using Spearman rank correlation, and the causal time-series relationship between occupational stress and elevated blood pressure over time was analyzed by cross-lagged path analysis modelling.Results:In the baseline data of petroleum workers, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 124.00 (119.00, 128.00) and 77.00 (73.00, 82.00) mmHg respectively, with an ORQ total score of 164.00 (154.00, 174.00) points. In the follow-up data, the SBP and DBP were 126.00 (123.00, 128.00) and 78.00 (75.00, 82.00) mmHg respectively, and the ORQ total score was 168.00 (157.00, 181.00) points. The results of the correlation analysis showed that the ORQ total score of petroleum workers was positively correlated with the levels of SBP and DBP ( P<0.05), and the ORQ total score at follow-up was negatively correlated with the baseline levels of SBP and DBP ( P<0.05). The results of the cross-lagged path analysis showed that the path coefficients from the baseline ORQ total score of petroleum workers to the follow-up SBP and DBP levels were statistically significant ( ρ=0.06, 0.06, P=0.032, 0.011). In terms of time sequence, the increase in the ORQ total score preceded the increase in the SBP and DBP levels. Conclusion:The occupational stress of petroleum workers is related to blood pressure, and the increase of occupational stress precedes the change of blood pressure. This correlation may increase the risk of hypertension among petroleum workers.

Objective:To compare the effects of the endoscopic retrograde appendicitis therapy (ERAT) assisted with 3 different methods in the diagnosis and treatment of children with uncomplicated appendicitis, and to explore the most effective ERAT.Methods:A case series study was made.The clinical data of 206 children with uncomplicated appendicitis who underwent ERAT in Ji′nan Children′s Hospital from January 2019 to December 2023 were retrospectively analyzed.The patients were divided into 3 groups according to the auxiliary treatment method adopted.There were 13 cases receiving X-ray guided ERAT (ERAT-X) group, 109 cases receiving B-ultrasound guided ERAT(ERAT-B) group and 84 cases receiving dong cha endoscope guided ERAT (ERAT-DC) group.Appendix cavity exploration, irrigation and fecalith removal were performed by ERAT.Perioperative data such as endoscopic manifestations, abdominal pain and the success rate of intubation and follow-up data were recorded and compared among the three groups of patients.The one-way ANOVA method, Wilcoxon sign rank sum test and Kruskal-Wallis H test were used to analyze measurement data, and the χ2 test was used to analyze enumeration data. Results:A total of 201 cases were successfully intubated, including 12 in the ERAT-X group, 106 in the ERAT-B group, and 83 in the ERAT-DC group.The mucosa of the appendix showed different inflammatory changes under the endoscope.There were no significant differences in abdominal pain score before treatment, abdominal pain score after treatment, success rate of intubation, effective rate of treatment, complication rate, antibiotic use rate and length of hospital stay among the three groups (all P>0.05).The abdominal pain score after treatment was significantly lower than that before treatment in all the 3 groups[0(1.00) points vs.4(1.50) points/0(1.00) points vs.4(2.00) points/0(1.00) points vs.4(1.75) points, Z=-3.082, -8.939, -8.009, all P<0.05].The diagnostic rate of the ERAT-DC group was lower than that of the ERAT-B group (75.0% vs.95.4%, P<0.05).The diagnostic specificity of ERAT-DC group was better than that of the ERAT-B group.The operation time of the ERAT-DC group was significantly reduced, compared with that of ERAT-X and ERAT-B groups[38.5(34.3) min vs.85.0(42.5) min vs.67.0(27.0) min, Z=80.075, 55.865, all P<0.05].The hospitalization cost of the ERAT-DC group was significantly higher than that of ERAT-X and ERAT-B groups[(17 269±1 035) yuan vs.(12 081±921) yuan vs.(11 609±1 479) yuan, Z=-89.308, -104.633, all P<0.05].Follow-up results showed that the recurrence rate of abdominal pain (9.1%, 16.7%, 14.8%) and the rate of unplanned reoperation (9.1%, 10.8%, 8.6%) showed no significant difference among the 3 groups(ERAT-X/ERAT-B/ERAT-DC) (all P>0.05). Conclusions:ERAT is a safe and effective therapy in treating children with uncomplicated appendicitis.EART-DC is more accurate and reliable method for the diagnosis and treatment of pediatric appendicitis, so it is worthy of widespread clinical application.
