Objective To study the relationship between serum visfatin, neutrophil-to-lymphocyte ratio (NLR) and disease severity of coronary heart disease (CHD) in elderly patients (≥90 years old). Methods One hundred and two elderly patients (≥90 years old) with CHD who received coronary CT angiography (CTA) were selected from January 2020 to June 2024. In addition, thirty-five elderly patients (≥90 years old) without CHD who underwent coronary CTA during the same period were included in the control group. The CHD patients were divided into mild group, moderate group and severe group by CT-SYNTAX score. The clinical data and levels of serum visfatin and NLR were compared, and the correlation and diagnostic value of the above levels with disease severity of CHD in elderly patients were analyzed. Results Serum visfatin and NLR were manifested as severe group>moderate group>mild group>control group (P<0.05). Pearson correlation analysis found that serum visfatin and NLR were moderately positively correlated with CT-SYNTAX score (r=0.574, 0.482, P<0.001). Receiver operating characteristics (ROC) curve indicated that the area under the curve (AUC) of combination of serum visfatin and NLR in diagnosing severe lesion in elderly patients (≥90 years old) with CHD was 0.882, which was higher than that of visfatin or NLR alone, and its 95%CI was 0.803-0.938. Conclusion There is a certain correlation between serum visfatin, NLR and disease severity of CHD in elderly patients. The combination of the above indicators has a higher predictive value on severe lesion.

Triple-negative breast cancer (TNBC) remains a refractory subtype of breast cancer due to its resistance to various therapeutic strategies. In this study, we introduce a "brake-release and accelerator-pressing" approach to engineer a microneedle patch embedded with copper-doped Prussian blue nanoparticles (Cu-PB) and the ferroptosis inducer sorafenib (SRF) for raised chemodynamic (CDT)/photothermal (PTT) combination therapy against TNBC. Upon transdermal insertion, the dissolving microneedles swiftly disintegrate and facilitate the release of SRF. Under gentle external light exposure, copper ions (Cu²⁺) and iron ions (Fe³⁺) were liberated from Cu-PB. The direct chelation of Cu²⁺ and the indirect suppression by SRF, collectively attenuate glutathione peroxidase 4 (GPX4) enzymatic function, destabilizing the cellular redox equilibrium (referred to as the "brake-release" strategy). The release of Cu²⁺ and Fe³⁺ ions instigates a Fenton/Fenton-like reaction within tumor cells, further yielding hydroxyl radicals and elevating reactive oxygen species (ROS) concentrations (referred to as the "accelerator-pressing" strategy). This overwhelming ROS accumulation, coupled with the impaired clearance of resultant lipid peroxides (LPO), ultimately triggers a robust ferroptosis cell death response. In summary, this study presents an innovative combinatorial therapeutic strategy based on dual-ferroptosis induction for TNBC, implying a promising therapeutic platform for developing ferroptosis-centered treatments for this aggressive breast cancer subtype.

Objective:To discuss the effect of sialic acid-binding immunoglobulin-like lectin-15(Siglec15)derived from M2 tumor-associated macrophages(M2-TAMs)on promoting the malignant biological behavior of the esophageal squamous cell carcinoma(ESCC)through bioinformatics analysis,and to validate the findings through cell experiment.Methods:The Tumor Immune Estimation Resource(TIMER)online Database was used to analyze the expression differences and immune infiltration of Siglec15 in pan-cancer and adjacent normal tissues.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of Siglec15 mRNA in M2-TAMs and ESCC EC109 and KYSE150 cells.Based on the non-contact co-culture of M2-TAMs and ESCC cells,the following groups were set up,such as EC109/KYSE150 group,EC109/KYSE150+si-NC group(transfected with si-NC sequence),and EC109/KYSE150+si-Siglec15 group(transfected with si-Siglec15#1 and si-Siglec15#2 sequences).CCK-8 method was used to detect the proliferation activities of the cells in various groups;wound healing assay was used to detect the wound healing rates of the cells in various groups;Transwell chamber assay was used to detect the numbers of migration and invasion cells in various groups;flow cytometry was used to detect the apoptotic rates of the cells in various groups.Results:The bioinformatics analysis results showed that compared with adjacent normal tissue,the expression levels of Siglec15 mRNA in pan-cancer tissues such as esophageal cancer,colon cancer,and head and neck squamous cell carcinoma tissues were increased(P＜0.05 or P＜0.01),and the expression level of Siglec15 mRNA in esophageal cancer tissue was significantly positively correlated with the infiltration of the macrophages(P＜0.05).Compared with the EC109 cells and KYSE150 cells,the expression level of Siglec15 mRNA in M2-TAMs was significantly increased(P＜0.01).There was no significant difference in the proliferation rate of the cells among EC109/KYSE150 group,EC109/KYSE150+si-NC group,and EC109/KYSE150+si-Siglec15 group(P＞0.05).Compared with EC109/KYSE150 group,after treated for 24 and 48 h,the wound healing rate of the cells in EC109/KYSE150+si-NC group was increased(P＜0.01),the numbers of migration and invasion cells were increased(P＜0.05),and the apoptotic rate was decreased(P＜0.01).Compared with EC109/KYSE150+si-NC group,the wound healing rates of the cells in EC109/KYSE150+si-Siglec15#1 group and EC109/KYSE150+si-Siglec15#2 group were decreased(P＜0.05),the numbers of migration and invasion cells were decreased(P＜0.05),and the apoptotic rates of the cells had no significant difference(P＞0.05).Conclusion:Siglec15 derived from M2-TAMs may be a key factor in promoting the migration and invasion of the ESCC cells.

Objective:To investigate the clinical efficacy of single-incision plus one-port three dimensional (3D) laparoscopic pancreaticoduodenectomy (SILPD+1).Methods:The retrospective cohort study was conducted. The clinicopathological data of 40 patients who underwent 3D laparos-copic pancreaticoduodenectomy in Affiliated Hospital of North Sichuan Medical College from January to October 2023 were collected. There were 24 males and 16 females, aged (63±10)years. Of the 40 patients, 18 cases undergoing SILPD+1 were divided into the SILPD+1 group, and 22 cases under-going conventional five-trocar 3D laparoscopic pancreaticoduodenectomy (CLPD) were divided into the CLPD group. Observation indicators: (1) surgical situations; (2) postoperative situations and complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney rank sum test. Results:(1) Surgical situa-tions. Seventeen patients of the SILPD+1 group completed surgery successfully, and the rest of one patient with an inflammatory mass of the pancreatic head was converted to open surgery due to unclear boundary with mesenteric blood vessels and severe adhesion of surrounding tissues. All patients of the CLPD group completed surgery successfully, without conversion to open surgery. There was no significant difference in conversion to open surgery between the two groups ( P>0.05), and there was no significant difference in the volume of intraoperative blood loss, intraoperative blood transfusion or operation time ( P>0.05). (2) Postoperative situations and complications. There was no significant difference in tumor diameter, the number of lymph node dissected, the number of positive lymph node, R 0 resection, tumor type, time to postoperative first flatus, time to postopera-tive first intake liquid food, tome to first out-of-bed activity, time to postoperative drainage tube removal, duration of postoperative hospital stay, postoperative bleeding, pancreatic fistula, chylous leakage, delayed gastric emptying, abdominal fluid collection, incision infection, classification of com-plications between the two groups ( P>0.05). Postoperative pain score of the SILPD+1 group and the CLPD group was 5.0(4.5,6.0) and 6.5(6.0,7.0), respectively, showing a significant difference ( Z=-3.61, P<0.05). Both groups of patients had no occurrence of biliary fistula or abdominal infection after surgery, and there was no readmission within 30 days after surgery or no death within 90 days after surgery. Conclusions:Compared with CLPD, SILPD+1 is safe and feasible, with less postoperative pain. While ensuring oncological outcomes, SILPD+1 does not increase surgical time, postoperative hospital stay, or incidence of postoperative complications.

OBJECTIVE To explore the self precipitation source of Erhuang powder, determine the content of related components and its efficacy on HeLa cells. METHODS Bifurcation study to identify the main compatibility of precipitating. The self precipitation, supernatant and extract of Erhuang powder were analyzed by UHPLC-Q-Exactive MS. The main compounds in Coptidis Rhizoma and Catechu, catechin, epicatechin, epicberberine, coptisine, berberine and palmatine were selected as controls. A analysis method of UHPLC for self precipitation, supernatant and extract of Erhuang powder was established and the related components were quantitatively determined. The effects of self precipitation, supernatant and extract on HeLa cells were evaluated by MTT method and flow cytometry. RESULTS A slight flocculation precipitate appeared when the decoction of Erhuang powder was mixed in pairs, while a large amount of flocculation appeared when the decoction of Coptidis Rhizoma and Catechu water was mixed. The self precipitation, supernatant and extract samples contained 39 compounds, which were mainly alkaloids and phenolic acids. The contents of catechin and berberine in the 6 index components were mostly, which accounted for 73.56% of the total content of the index components in self precipitation and 61.89% of the total content of the index components in extract. Inhibition effect on HeLa cells: extract ≈ self precipitation > supernatant, and inducing apoptosis: self precipitate ≈ extract, supernatant had no apoptosis-inducing effect. CONCLUSION Coptidis Rhizoma-Catechu is the main compatible formula for precipitation formation. The self precipitation and extracts of Erhuang powder are mainly alkaloids and phenolic acids, among which berberine and catechin are high in content and can be used as representative components. The effect of self-precipitation and extract on HeLa cells was better than that of supernatant. This basically indicates that the self precipitation components and pharmacological effects of Erhuang powder are similar to those of the extract.
