With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

Objective To investigate the correlation between peripheral blood total bilirubin(TBIL)levels and the efficacy and prognosis of immunotherapy in advanced non-small cell lung cancer(NSCLC),as well as its relationship with immune inflammation.Methods A retrospective analysis was conducted on 246 patients with advanced NSCLC who received immunotherapy from June 2019 to June 2022.Pre-treatment TBIL levels were collected,and the optimal cutoff value for TBIL was determined using the"X-tile"software and the ROC curve.The impact of pre-treatment TBIL on the short-term efficacy and long-term prognosis of advanced NSCLC was an-alyzed.Results The optimal cutoff value for TBIL was identified as 10.5μmol/L using the"X-tile"software and the ROC curve.A-nalysis of short-term efficacy indicated that patients with higher TBIL levels had a significantly better objective response rate(ORR)compared to those with lower levels(51.3％vs 33.8％,P=0.006).The disease control rate(DCR)was also higher in the higher TBIL level group compared to the low level group(92.9％vs 81.2％,P=0.007).Kaplan-Meier survival analysis revealed that patients with elevated TBIL levels had a longer median progression-free survival(PFS)compared to those with lower TBIL levels,with 13.0 vs 7.0 months,respectively(P＜0.001).Similarly,the median overall survival(OS)was greater in the higher TBIL level group than in the lower TBIL level group,with 16.0 vs 12.0months,respectively(P＜0.001).Additionally,there were significant differences in neutro-phil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and systemic immune-inflammation index(SII)between two groups of different TBIL levels(P＜0.05).Conclusion In immunotherapy for advanced non-small cell lung cancer,patients with higher baseline levels of TBIL exhibit a positive correlation with the efficacy and prognosis of immunotherapy.TBIL might be served as an important predictive marker for immunotherapy in patients with advanced NSCLC.

Objective:To compare the clinical manifestations,laboratory results,and imaging features between pyogenic spondylitis(PS) and tuberculous spondylitis(TS).Methods:This was a cross-sectional study. A total of 88 patients with infectious diseases of spine(IDS) admitted to Shanghai Sixth People′s Hospital from January 2021 to December 2023 were analyzed,including 61 PS cases(PS group) and 27 TS cases(TS group). The clinical manifestations,laboratory results,and imaging features were compared between two groups. The factors associated with PS were analyzed by multivariate logistic regression. The diagnostic efficacy for pathogen identification was compared between metagenomics next-generation sequencing(mNGS) and bacterial culture methods in PS and TS patients.Results:Compared with the TS group,the PS group had a higher age-adjusted Charlson comorbidity index(aCCI)[3.0(1.5,4.0) points vs. 2.0(1.0,3.0) points, Z=-2.189, P=0.029],shorter onset time of disease[1.0(0.8,3.0) months vs. 6.0(2.0,12.0) months,Z=-4.353, P<0.001],and higher median blood leukocyte counts and serum ferritin(SF) level(7.2×10 9/L vs. 6.3×10 9/L, Z=-2.652, P=0.008; 571.3 ng/ml vs. 266.0 ng/ml, Z=-4.773, P<0.001). The proportions of lumbar spine involvement,non-collapsed involved vertebrae,and bone bridges formed were all higher in the PS group compared to the TS group[68.8%(99/144) vs. 41.4%(29/70), χ2=14.628, P<0.001; 68.9%(42/61) vs. 18.5%(5/27), χ2=19.055, P<0.001; 41.0%(25/61) vs. 7.4%(2/27), χ2=9.921, P=0.002]. The proportions of thoracic spine involvement,severe vertebral collapse,severe narrowing of the involved intervertebral space,sequestrum,and paravertebral soft tissue calcification were all higher in the TS group compared to the PS group[52.9%(37/70) vs. 18.1%(26/144), χ2=27.463, P<0.001; 55.6%(15/27) vs. 13.1%(8/61), χ2=17.462, P<0.001; 74.1%(20/27) vs. 37.7%(23/61), χ2=9.907, P=0.002; 74.1%(20/27) vs. 18.0%(11/61), χ2=25.761, P<0.001; 51.9%(14/27) vs. 6.6%(4/61), χ2=23.599, P<0.001]. Multivariate logistic regression analysis indicated that a symptom duration<5.5 months( OR=30.644,95% CI: 2.022-464.529, P<0.05) and a leukocyte count>7.35×10 9/L( OR=48.653,95% CI: 2.045-1 157.721, P<0.05) indicated a higher likelihood of PS; while the vertebral collapse indicated a higher likelihood of TS( OR=0.025,95% CI: 0.001-0.638, P<0.05). The most common pathogen in the PS group was Staphylococcus aureus(31 cases,50.8%),followed by Streptococcus species(10 cases,16.4%). The positive rates of mNGS testing in the PS and TS groups were 84.1%(37/44) and 12/13,respectively,which were higher than those of conventional bacterial culture[77.8%(42/54)] and Mycobacteriumtuberculosis culture(2/11). Conclusions:Compared with the TS patients,the PS patients have shorter onset time,higher aCCI scores,higher blood leukocyte counts and SF levels,less vertebral collapse and intervertebral space narrowing,and more bone bridge formation. The TS patients have more dead bones and calcifications. The mNGS has a higher diagnostic efficacy than bacterial cultures for PS and TS.

Objective:To investigate the status and influencing factors of substantial weight retention in patients with gestational diabetes mellitus (GDM) in early postpartum.Methods:This cross-sectional study employed a convenience sampling method to select 373 patients with GDM who underwent a 6-week postpartum health check at the Postpartum Health Clinic of Women′s Hospital of Nanjing Medical University from February to July in 2023. According to postpartum weight retention (PPWR) on the survey day, the participants were divided into a substantial PPWR group (≥5 kg, 139 cases) and a non-substantial PPWR group (<5 kg, 234 cases). Independent sample t-tests and χ2 tests were used to compare differences in demographic data, clinical data, and biochemical indicators between the two groups. Binary logistic regression was used to analyze the influencing factors of early substantial postpartum weight retention in patients with GDM. Results:A total of 37.27% (139/373) of GDM patients experienced substantial postpartum weight retention at 6 weeks postpartum. The rates of diabetes in family history, excessive gestational weight gain, gestational hypertension, and infant neonatal intensive care unit (NICU) admission in substantial PPWR group were all significantly higher than those in the non-substantial PPWR group (32.37% vs 23.08%, 73.38% vs 20.09%, 13.67% vs 5.56%, 21.58% vs 9.83%) (all P<0.05); but the proportion of overweight or obese before pregnancy and postpartum self-monitoring of blood glucose were both lower in the substantial PPWR group than those in the non-substantial PPWR group (25.18% vs 41.03%, 17.99% vs 27.78%)(all P<0.05). Binary logistic regression indicated that family history of diabetes ( OR=2.826, 95% CI: 1.517-5.265), excessive gestational weight gain ( OR=19.240, 95% CI: 10.360-35.732), and infant NICU admission ( OR=2.447, 95% CI: 1.150-5.205) were positively related to the occurrence of substantial weight retention in patients with GDM in early postpartum, whereas pre-pregnancy overweight or obesity ( OR=0.189, 95% CI: 0.100-0.360) was negatively correlated to substantial weight retention in patients with GDM in early postpartum (all P<0.05). Conclusion:Substantial weight retention is prevalent among GDM patients in early postpartum, which is significantly influenced by family history of diabetes, pre-pregnancy overweight or obesity, excessive gestational weight gain, and infant NICU admission history.

Objective To profile ubiquitination in cysteinyl aspartate-specific proteinase-2(CASP2)deficient cells under heat shock and investigate the role of CASP2 in stress response.Methods Ubiquitination levels in subcellular fractions of control and C ASP2 knockout(KO)cells were detected via Western blotting.After 2 hours of heat shock treatment,Soluble Ⅱ and Pellet fractions were collected from both control and CASP2 KO cells for ubiquitinome analysis.Anti-di-glycine remnant(K-ε-GG)antibody-based proteomic analysis was performed to identify differentially ubiquitinated proteins and associated key signaling pathways.Proteins that displayed significantly upregulated ubiquitination in CASP2 KO cells under heat shock were subjected to His-tag pull-down assays to find out whether CASP2 regulated the ubiquitination of these proteins.Results Under heat shock,CASP2 KO cells displayed significantly higher accumulation of overloaded ubiquitinated conjugates in the Pellet fraction compared to controls.Ubiquitinomics analysis revealed substantial alterations in protein ubiquitination patterns following CASP2 KO.One hundred proteins exhibited significantly elevated ubiquitination levels while 36 proteins had their ubiquitination reduced relative to controls.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis indicated that hyper-ubiquitinated proteins were primarily associated with Huntington disease,Alzheimer disease,bile secretion,carbon metabolism and autophagy.His-tag pull-down assays combined with Western blotting revealed increased ubiquitination of nicotinamide adenine dinucleotide reduced-ubiquinone oxidoreductase 1 beta subcomplex subunit 3(NDUFB3)and autophagy-related protein 9A(ATG9A)in CASP2 KO cells under heat shock.Conclusion Overloaded ubiquitinated conjugates are accumulated due to CASP2 deficiency during heat shock.CASP2 modulates ubiquitination levels through multiple signaling pathways.
