With the aging population and the widespread implementation of lung cancer screening programs, an increasing number of elderly patients are undergoing curative lung resection. Due to diminished physiological reserve and complex comorbidities, this demographic exhibits a significantly higher incidence of severe perioperative complications (defined as Clavien-Dindo grade≥Ⅲ), which adversely affects both perioperative safety and long-term prognosis. In recent years, the research paradigm has shifted from univariate analysis toward multidimensional risk integration and the development of predictive models. This article systematically reviews the key risk factors for severe perioperative complications in elderly lung cancer patients, encompassing biological aging processes, frailty and sarcopenia, cardiopulmonary and renal functional reserves, inflammatory-immune and coagulation status, and perioperative interventions. Furthermore, it traces the evolution of risk assessment tools from traditional regression models to machine learning models that integrate multimodal data. The review also discusses common challenges in this field, including the standardization of outcome definitions, external validation, calibration assessment, and clinical translation. Future efforts should prioritize the deep integration of predictive tools with clinical decision support systems to establish a closed-loop care pathway from risk identification to stratified intervention, thereby effectively reducing complication rates and enhancing surgical outcomes for elderly lung cancer patients.

Objective To explore the value of inflammatory load index(IBI)in the diagnosis and prognosis of gastric cancer patients.Methods Clinical data of patients who underwent gastric cancer surgery in the Department of General Surgery of the Second Hospital of Lanzhou University from January 2016 to December 2018 were retrospectively analyzed,and the patients were divided into the high IBI group and the low IBI group based on the optimal cut-off value of IBI.ROC curve was used to determine the optimal cut-off value of IBI,and the survival curve was constructed using the Kaplan-Meier method,and the differences between groups were examined using the Log-rank test.Cox regression analysis was performed to study the prognostic factors of gastric cancer patients.Results The best cut-off value for IBI diagnosis was 8.796,and the best cut-off value for prognosis was 28.75.IBI was related to the clinical case characteristics of gastric cancer patients,such as surgical access,the degree of differentiation,CK7,CK20,LMP-1,and Ki-67(P＜0.05).The results of univariate analysis showed that intraoperative bleeding,preoperative CEA,preoperative CA125,preoperative CA199,IBI,tumor diameter size,margins of incision,vascular invasion,nerve invasion,pT stage and pN stagewere the influencing factors on the prognosis of gastric cancer patients(P＜0.05).The results of multifactorial regression analysis showed that intraoperative bleeding,preoperative CEA,preoperative CA199,IBI,tumor diameter size,pT stage and pN stagewere independent risk factors affecting the prognosis of gastric cancer patients(P＜0.05).The median OS of patients in the high IBI group and low IBI group were 32.9 months and 74.8 months,respectively,with statistically significant differences(P＜0.001).Conclusion IBI is an independent risk factor for poor prognosis of patients with gastric cancer,and it has a good predictive value in diagnosis and prognosis.

BACKGROUND:Neuroinflammation is a major cause of exacerbation after spinal cord injury.In recent years,pyroptosis has received much attention due to its remarkable pro-inflammatory features.Some of these natural products can significantly inhibit the inflammatory response and improve the damaged nerve function by regulating the level of pyroptosis after spinal cord injury,which provides a new therapeutic idea for spinal cord injury.OBJECTIVE:To summarize the mechanism of action of natural products in regulating pyroptosis for the treatment of spinal cord injury,with a view to providing lessons and references for future research on the treatment of spinal cord injury.METHODS:The search terms"spinal cord injury,pyroptosis,inflammasome,natural products,natural compounds,traditional Chinese medicine"in Chinese and English were used to search for relevant literature since the establishment of the database up to September 2024 in the databases of PubMed,Web of Science,WanFang,and CNKI.According to the inclusion and exclusion criteria,75 relevant articles were finally obtained.RESULTS AND CONCLUSION:(1)Pyroptosis is an important pro-inflammatory pathway in spinal cord injury,and controlling pyroptosis is an effective way to improve damaged nerve function.(2)Some natural products can regulate pyroptosis via the NLRP3/Caspase-1 classical pyroptosis pathway,the NF-κB-related pathway,other upstream pathways such as Nrf2/HO-1,and autophagy,thereby affecting the level of tissue inflammation and accelerating neurological recovery after spinal cord injury.(3)The anti-pyroptosis effects of these natural products are mostly dependent on the NLRP3 classical pyroptosis pathway,and there is a lack of studies on other pyroptosis pathways.(4)There are still many problems in this field,such as the fact that these natural products are not currently supported by evidence from appropriate clinical studies.(5)The natural product has great potential in regulating pyroptosis and is expected to be a powerful weapon in the treatment of spinal cord injury.

Cholesterol-lowering therapy is necessary in patients with hypercholesterolaemia, particularly those at high risk of atherosclerotic cardiovascular disease(ASCVD). However, in clinical practice, it is important to avoid initiating lipid-modifying treatment indiscriminately without first identifying the underlying cause. Several key principles should be emphasized in lipid management. First, cholesterol reduction should be appropriate, avoiding excessive lowering that could lead to overcorrection. Second, comprehensive management is crucial; for patients with ASCVD, lifestyle modification, including weight reduction, smoking cessation, limiting alcohol consumption, and alleviating anxiety, as important as lipid-modifying therapy. Additionally, attention should be paid to the potential adverse effects of low cholesterol levels, which warrant close monitoring throughout treatment. Finally, further evidence is needed to address the ongoing controversies regarding certain clinical outcomes.

Objective:To identify the risk factors for perioperative cardiac arrest (POCA) in elderly patients undergoing general anesthesia.Methods:This case-control study enrolled elderly patients aged ≥60 yr who underwent surgery under general anesthesia at Peking Union Medical College Hospital between January 1, 2013, and November 30, 2024. The case group consisted of patients who experienced POCA, defined as cessation of cardiac mechanical activity and loss of effective circulation, requiring immediate chest compressions and/or defibrillation within 24 h from entering the operating room to the end of anesthesia. The control group consisted of elderly patients without POCA, matched to cases by sex and date of surgery in a ratio of 1∶3. Univariate analysis and multivariate logistic regression were performed to identify independent risk factors for POCA based on patients′ baseline and surgical characteristics.Results:A total of 53 POCA cases and 159 matched controls were included. The results of multivariate logistic regression analysis identified an American Society of Anesthesiologists Physical Status classification of ≥Ⅲ ( OR=4.90, 95% confidence interval [ CI] 2.21-10.89, P<0.001) and the presence of peripheral vascular disease ( OR=2.53, 95% CI 1.10-5.81, P=0.028) as independent risk factors for POCA. Higher preoperative hemoglobin concentration was found to be a protective factor ( OR=0.97, 95% CI 0.95-0.99, P<0.001). Conclusions:An American Society of Anesthesiologists Physical Status classification of ≥Ⅲ and comorbid peripheral vascular disease are independent risk factors for POCA in elderly patients undergoing general anesthesia, while higher preoperative hemoglobin concentration serves as a protective factor.
