To address the growing challenge of an increasing number of elderly lung cancer patients amidst China's aging population and to fill the gap in quality control standards for surgical treatment in this special population, this study aimed to develop a standardized surgical evaluation system for elderly lung cancer patients tailored to China's national conditions. The system was established through a literature review, integrated the pathophysiological characteristics of elderly patients, and was constructed following review, feedback, and revision by experts from multiple thoracic surgery centers. Employing a 100-point scoring system, it comprises three primary domains: physical infrastructure and geriatric adaptability foundational conditions (10 points); management level and perioperative care models (20 points); and technical proficiency and clinical outcomes (70 points). The system places a strong emphasis on geriatric adaptability, proposing specific, quantifiable indicators for age-friendly facility modifications, control of elderly-specific complications, multidisciplinary collaboration, and standardized perioperative management. It provides a convenient and measurable assessment tool for quality control in the surgical treatment of elderly lung cancer in China, which is expected to promote the standardization and homogenization of diagnosis and treatment.

This article summarizes the nursing experience of a patient who underwent percutaneous transluminal septal branch microsphere embolization combined with MitraClip surgery.Nursing key points:before the operation,a multidisciplinary case nursing team was established to jointly optimize the surgical risk plan;checklist-based nursing management was adopted to fully implement preoperative preparations;dynamic psychological assessment was conducted and early psychological intervention was carried out.Intraoperative monitoring and prevention of complications were well implemented.Postoperative care:close monitoring of cardiac function;good volume management to maintain electrolyte balance;implementation of risk management for bleeding or thrombosis;enhanced care for urethral bleeding.The patient was discharged 11 days after the operation and followed up for 3 months.The 6-minute walk distance increased from 240 m before the operation to 560 m,and the patient returned to normal life.

Objective:To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer.Methods:This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery, Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by independent sample t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher′s exact test. Results:A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant ( χ2 value were 156.24, 4.08, 36.56, P value were <0.01, 0.043,<0.01). Conclusion:Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.

Objective To investigate the effect of the aqueous extract of Chuan Xiong Rhizoma(CR)on brain metastasis of melanoma B16F10 cells in mice.Methods C57BL/6J mouse models of brain metastasis of melanoma were established by ultrasound-guided intraventricular injection of Luc-labeled B16F10 cells,and brain tumor growth was monitored by in vivo imaging.The mouse models were then randomized for daily gavage of saline or aqueous extract of CR(equivalent crude drug concentration of 1 mg/g).Behavioral tests were used to evaluate the neuroprotective effects of CR in the tumor-bearing mice,and the changes in proteins associated with blood-brain barrier integrity,neuronal cell proliferation and apoptosis,and microglial cell apoptosis and activation were observed using immunofluorescence assay.The efficacy of CR combined with temozolomide(25 mg/kg)against brain metastases of B16F10 cells was observed by in vivo imaging.Results CR-treated mouse models did not show obvious progression of brain metastases and had a reduced rate of body weight loss and lowered protein expressions of ZO-1,claudin-5,occludin,P-gp,TNF-α,AQP4 and PDGFRβ.In the behavioral tests,the CR-treated mice showed prolonged stay on the wooden stick with a shortened time of sticky stick removal.Immunofluorescence assay showed increased proliferation and decreased apoptosis of neuronal cells and microglia in CR-treated mice.CR treatment significantly increased the levels of CD86,CD206,IL-4 and IL-10 and decreased the levels of CD163 and IL-1β in the microenvironment of brain metastases.The mice receiving combined treatments with CR and temozolomide showed significantly lower intensity of fluorescent signals in the brain than those treated with temozolomide alone.Conclusion CR does not promote brain metastasis of melanoma while inducing opening of the blood-brain barrier,and its combined use with TMZ results in enhanced inhibition against brain metastasis of melanoma B16F10 cells in mice.

Objective To investigate the effect of Euphorbia helioscopia on biological behaviors of non-small cell lung cancer(NSCLC)cells.Methods NSCLC cell lines PC-9 and A549 treated with different concentrations of Euphorbia helioscopia preparations were examined for changes in proliferation,apoptosis,invasion and migration using CCK-8 assay,colony formation assay,flow cytometry,wound healing assay and Transwell assay.Western blotting was performed to detect the changes in protein expressions of Bax,Bcl-2,E-cadherin,vimentin,MMP2,and MMP9 in the treated cells.PC-9 cells were injected subcutaneously into BALB/C nude mice to establish a nude mouse subcutaneous tumor model.According to the growth of subcutaneous tumors,mice were randomly divided into control group:gavaged daily with saline;Euphorbia helioscopia-treated group:gavaged daily with Euphorbia helioscopia 65 mg/mL,and Euphorbia helioscopia granules were dissolved in saline;cisplatin-treated group:injected intraperitoneally with cisplatin 4 mg/kg every 5 days,6 mice per group.The subcutaneous tumor volume and mass changes of mice were measured,and the toxic effects of Euphorbia helioscopia on heart,liver,spleen,lung and kidney as well as the therapeutic effects of Euphorbia helioscopia were observed in the mice bearing tumor.Results Euphorbia helioscopia granules concentration-dependently inhibited the proliferation and survival of PC-9 and A549 cells,significantly promoted cell apoptosis,suppressed invasion and migration abilities of the cells,up-regulated the expression levels of E-cadherin and Bax,and down-regulated the expressions of Bcl-2,vimentin,MMP2,and MMP9.In the tumor-bearing mice,treatment with Euphorbia helioscopia significantly inhibited tumor growth without producing obvious toxicity in the vital organs.Conclusion Euphorbia helioscopia can inhibit proliferation,invasion,and migration and induces apoptosis of NSCLC cells in vitro.

Objective To investigate the inhibitory effect of aumolertinib combined with anlotinib on proliferation of non-small cell lung cancer(NSCLC)cells.Methods CCK-8 assay,colony formation assay,and flow cytometry were used to assess the effect of different concentrations of aumolertinib or anlotinib on proliferation,survival,and apoptosis of PC-9 and HCC827 cells,and their synergistic effect was evaluated using the SynergyFinder model.In PC-9 and HCC827 cells treated with aumolertinib combined with anlotinib,the changes in cell invasion and migration abilities were assessed with Transwell assay,and the expressions of apoptosis-and invasion/migration-related proteins(Bax,Bcl-2,E-cadherin,vimentin,MMP2,and MMP9)and the key PI3K-Akt pathway proteins were detected using Western blotting.Results In PC-9 cells,the IC50 of aumolertinib and anlotinib was 1.701 μmol/L and 4.979 μmol/L,respectively,with a synergy score(ZIP)of 19.112;in HCC827 cells,their IC50 was 2.961 μmol/L and 7.934 μmol/L,respectively,with a ZIP of 12.325.Compared with aumolertinib and anlotinib used alone,their combined treatment more strongly inhibited the proliferation and survival,enhanced apoptosis and suppressed invasion and migration abilities of PC-9 and HCC827 cells.Western blotting showed that in both PC-9 and HCC827 cells,the combined treatment significantly upregulated the expressions of E-cadherin and Bax proteins,downregulated the expressions of Bcl-2,vimentin,MMP2,and MMP9 proteins,and reduced phosphorylation levels of PI3K and Akt.Conclusion Aumolertinib combined with anlotinib can effectively inhibit NSCLC cell proliferation by downregulating the PI3K-Akt pathway,suggesting a potentially new option for NSCLC treatment.
