With the advancement of the times and technology, the proportion of early gastric cancer has been increasing year by year, and its treatment methods have shifted towards more minimally invasive approaches, with better function-preserving and postoperative quality of life. Function-preserving surgery has gradually become the mainstream surgical option for early gastric cancer. Function-preserving surgeries mainly include segmental gastrectomy, pylorus-preserving gastrectomy, local gastrectomy, and sentinel lymph node navigation surgery. Although significant progress has been made in various function-preserving surgeries in recent years, there are still controversies regarding the selection of surgical indications, assessment of tumor radicality, surgical safety, and postoperative gastric function evaluation. Further high-quality evidence-based research is still needed to confirm the safety and effectiveness of function-preserving surgery for early gastric cancer.

Objective:To investigate the diagnostic and prognostic value of systemic immune inflammatory index (SII) for severe traumatic brain injury secondary to acute lung injury (sTBI-ALI).Methods:A retrospective study was conducted on patients with severe traumatic brain injury admitted to the trauma center of the First Affiliated Hospital of Soochow University from January 2021 to November 2023. Patients received standard treatments including hemostasis and intracranial pressure management. Vital signs and blood routine data were collected upon admission. Patients were categorized into sTBI group and sTBI-ALI group based on established clinical diagnostic criteria for ALI to evaluate the diagnostic utility of SII. Subsequently, within the sTBI-ALI group, patients were stratified into survival and non-survival groups based on their 30-day outcomes to assess the prognostic value of SII.Results:A total of 260 sTBI patients were enrolled, of whom 113 developed ALI. Among the sTBI-ALI patients, 73 survived at 30 days. Compared to the sTBI group, the sTBI-ALI group exhibited significantly higher respiratory rates, heart rates, white blood cell counts, neutrophil counts, platelet counts, and SII levels (all P<0.05). Multivariate logistic regression analysis showed that SII index ( OR=1.003, 95% CI: 1.002-1.004, P<0.001) was an independent risk factor for ALI development in sTBI patients. The combined predictive model incorporating SII and heart rate yielded an AUC of 0.801 (95% CI: 0.740-0.862). The non-survival group had significantly higher neutrophil counts and SII levels, and significantly lower Glasgow Coma Scale scores than the survival group (all P<0.05). Multifactorial regression analysis indicated that SII index ( OR=1.002, P=0.004, 95% CI: 1.000-1.003) served as an independent risk factor for 30-day mortality in sTBI-ALI patients. The combined predictive model of SII and GCS achieved an AUC of 0.904 (95% CI: 0.848-0.960). Conclusions:SII demonstrates potential as a biomarker for predicting the development of ALI following sTBI. Furthermore, incorporating SII into predictive models significantly enhances the ability to forecast mortality risk in sTBI-ALI patients.

Aim To investigate the effect of Shenqi Dihuang decoction(SQDH)on henoch-schonlein pur-pura nephritis(HSPN)rats by regulating AMPK/Sirt1/Nrf2 mediated ferroptosis and the possible mech-anism.Methods Thirty SD rats were randomly divid-ed into a control group(Control),HSPN group,SQDH low-dose group(SQDH-L,5.4 g·kg-1),SQDH high-dose group(SQDH-H,21.6 g·kg-1),and SQDH high-dose+AMPK inhibitor group(SQDH-H+CC,20 mg·kg-1),with six rats in each group.Except for the control group,all other groups of rats were injected intraperitoneally with ovalbumin and complete Freund's adjuvant to establish HSPN rat models.After the successful construction of the model,each group of rats was orally administered with the cor-responding dosage or physiological saline once a day for five weeks.HE staining was used to observe the his-topathological changes in renal tissues;immunohisto-chemistry(IHC)was employed to detect the deposition of IgA and IgG in renal tissues;serum biochemical pa-rameters of renal function and urinary protein levels were measured;commercial assay kits were utilized to determine oxidative stress markers and Fe2+levels in renal tissues;Western blot analysis was performed to assess ferroptosis-related proteins and the protein ex-pression of the AMPK/Sirt1/Nrf2 signaling pathway in renal tissues.Results Compared with the control group,the HSPN group showed significant pathological damage in kidney tissue,with significantly increased scores,increased deposition of IgA and IgG in kidney tissue,decreased serum total protein(TP)and albu-min(ALB),and average increases in serum creatinine(Cre),urea nitrogen(BUN),and urinary protein levels(P<0.05).The levels of MDA,ROS,Fe2+,and ACSL4 protein expression in the kidney tissue sig-nificantly increased,while SOD activity,SLC7A11,GPX4,p-AMPK/AMPK,Sirt1,and Nrf2 protein ex-pression significantly decreased(P<0.05).Com-pared with the HSPN group,the pathological damage to renal tissue was reduced,IgA and IgG deposition in renal tissue decreased,TP and ALB decreased,Cre,BUN,and urinary protein levels were all reduced(P<0.05),and the levels of MDA,ROS,Fe2+,and ACSL4 protein expression in renal tissue were signifi-cantly reduced in each dose group of SQDH rats.SOD activity,SLC7A11,GPX4,p-AMPK/AMPK,Sirt1,and Nrf2 protein expression significantly increased(P<0.05).Compared with the SQDH-H group,the AMPK inhibitor CC could inhibit the AMPK/Sirt1/Nrf2 signaling pathway induced ferroptosis and reverse the protective effect of SQDH on renal injury in HSPN rats.Conclusions SQDH can improve renal injury in HSPN rats,and its mechanism may be related to the activation of AMPK/Sirt1/Nrf2 signaling pathway to in-hibit ferroptosis.

[Objective] To explore the number of examined lymph nodes (ELN) and positive lymph node ratio (LNR) in the prediction of 5-year and 10-year overall survival (OS) and cancer-specific survival (CSS) of prostate cancer (PCa) patients, so as to provide reference for clinical practice. [Methods] Information of PCa patients screened in the Surveillance, Epidemiology and End Results (SEER) database during 2010-2020 were analyzed. A total of 1842 PCa patients were assigned to the training set (n=1290) and validation set (n=552) in a 7∶3 ratio with R 4.3.0 software. Significant factors in the multivariate Cox proportional risk regression model were adjusted, restricted cubic spline plots (RCS) were plotted, the optimal cut-off values of ELN and LNR were determined, and the 5-year and 10-year OS and CSS were analyzed with restricted mean survival time (RMST). [Results] Multivariate Cox analysis showed that there was a 2.9% reduction in the risk of death with an increase of 1-unit ELN and a 3.1% reduction in the risk of cancer-specific death. There was a 481.4% increase in the risk of death with a 1-unit increase in LNR and a 667.5% increase in the risk of cancer-specific death. The risk of overall death and cancer-specific death in ELN and PCa patients showing a non-linear relationship (P<0.001), while in the LNR and PCa patients showing a linear relationship (P>0.05). RMST results showed that the optimal ELN range for evaluating OS was 12-29, the optimal ELN range for assessing CSS was 12-25, LNR>0.152 indicated poor prognosis. [Conclusion] We have clarified the range of ELN and LNR, which can provide reference for the clinical precision diagnosis and treatment of PCa.

In addition to providing energy for cells, mitochondria also participate in calcium homeostasis, cell information transfer, cell apoptosis, cell growth and differentiation. Therefore, maintaining mitochondrial homeostasis is very crucial for the body to carry out normal life activities. Ubiquitination, a post-translational modification of proteins, is involved in various physiological and pathological processes of cells by regulating mitochondrial homeostasis. However, the mechanism by which ubiquitination regulates mitochondrial homeostasis has not been summarized, especially the effect of Parkin protein on cardiovascular diseases. In this paper, the specific mechanism of mitochondrial homeostasis regulated by ubiquitination of Parkin protein is discussed, and the influence of mitochondrial homeostasis imbalance on cardiovascular diseases is reviewed, with a view to providing potential therapeutic strategies for the clinical treatment of cardiovascular diseases.
