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.

To evaluate the reliability of flash continuous glucose monitoring(CGM) and itsaccuracy in supporting clinical decision-making after pancreatic surgery. This was a single-center retrospective secondary analysis derived from a multicenter prospective cohort study. Adult patients undergoing elective pancreatic surgery at Peking Union Medical College Hospital between March 2024 and March 2025 were enrolled. All patients had a CGM sensor placed on the left upper arm one day before surgery, with monitoring continued until at least postoperative day 7. The sensor measured interstitial fluid glucose every minute and allowed real-time scanning to obtain instant glucose values. In parallel, all patients underwent point-of-care(POC) blood glucose testing postoperatively. Paired glucose measurements at the same time points were identified using the Gplus glucose management system and the hospital information system. The mean absolute relative deviation(MARD) was calculated to assess the degree of deviation between the two methods. Agreement was evaluated using Bland-Altman analysis, and the clinical accuracy of CGM for decision support was assessed using Parkes error grid analysis. A total of 255 patients were ultimately included, with a median CGM wear time of 276.3(204.8, 314.1) hours. A total of 829 paired CGM and POC glucose values were obtained. The MARD between CGM values and POC glucose measurements was 14.10%. Bland-Altman analysis showed a mean difference of -18.72 mg/dL between the two methods, with 95% limits of agreement ranging from -69.88 to 32.44 mg/dL. The dispersion of differences widened progressively with increasing glucose levels, indicating marked heteroscedasticity. Parkes error grid analysis demonstrated that 99.88% of the paired glucose deviations fell within zones A and B, suggesting high accuracy of CGM in supporting correct clinical decisions. Flash CGM demonstrates generally satisfactory reliability for postoperative glucose monitoring following pancreatic surgery, with a low risk of harmful clinical decisions attributable to monitoring deviations. However, the measurement bias increases significantly with higher glucose levels, indicating that in the setting of severe hyperglycemia, CGM readings should be clinically calibrated and interpreted with caution in conjunction with POC blood glucose testing.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.

7.Application of ECMO in perioperative airway management
Basic & Clinical Medicine 2025;45(4):422-427
Traditional airway management techniques may fail to provide adequate oxygenation and ventilation for high-risk patients in complex cases.As an extracorporeal life support(ECLS)technology,extracorporeal membrane oxygenation(ECMO)offers continuous oxygenation and homodynamic support for these patients and provides critical assistance in perioperative airway management.ECMO can be applied in various scenarios,including diffi-cult airways,complex airway surgeries and emergency airway management.It plays a vital role in ensuring peri-op-erative safety,optimizing surgical field exposure,reducing the risk of severe peri-operative complications and im-proving clinical outcomes.

OBJECTIVE:
To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases.
METHODS:
TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases.
RESULTS:
Increased TB risk was linked to PM 2.5, PM 10, and rainfall, whereas NO 2, SO 2, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM 2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM 10 ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO 2 ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO 2 ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM 2.5 on TB.
CONCLUSION
Exposure to PM 2.5, PM 10, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

Journal of Surgery Concepts & Practice 2025;30(3):185-191
As a multifactorial chronic metabolic disorder with complex causes and serious health risks, obesity has drawn significant societal and medical attention. This article systematically reviewed the latest advancements in the clinical diagnosis and treatment of obesity. A disease-centered diagnosis and treatment concept has been proposed, which combines BMI and introduces a brand-new clinical diagnosis and treatment standard centered on fat content and functional disorders, such as new diagnostic markers like adipose tissue distribution, visceral adiposity, and waist-to-height ratio, to conduct a comprehensive assessment and lifespan management of patients. In recent years, novel biomarkers and artificial intelligence (AI)-assisted diagnosis have provided new tools for the diagnosis and treatment of obesity. In terms of treatment, combined therapy based on lifestyle and behavioral intervention has been widely recognized. The advent of new weight-loss drugs, such as glucagon-like peptide-1(GLP-1), minimally invasive techniques such as endoscopic sleeve gastrectomy(ESG), which reduced surgical risks, have provided possibilities for the treatment of obesity. The current concept of obesity management has become increasingly mature, feasible, and standardized. The construction principles of a weight management center, characterized by centralized management and individualized treatment, ensure the long-term stability of body weight and promote a healthy quality of life for patients with obesity.
