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 develop a postoperative self-management question prompt list for adult liver transplant recipients and conduct preliminary application,aiming to provide an effective tool for facilitating their engagement in postoperative self-management.Methods From August to September 2024,the first draft of the postoperative self-management question prompt list for adult liver transplant recipients was developed through literature search and qualitative interviews,including 9 primary items and 50 secondary items.From October to November 2024,16 experts from Qingdao,Jinan,Beijing,and Fuzhou were interviewed on the Delphi method for 2 rounds to revise the question prompt list.From February to March 2025,19 patients after liver transplantation were selected for the preliminary application of the question prompt list.Results The response rates in the 2 rounds of consultations were both 100％and the authority coefficients of experts were both 0.88.The Kendall's W in the 2 rounds was 0.336 and 0.344(P＜0.001),respectively.The final question prompt list includes 9 primary items and 49 secondary items.The study showed that QPL demonstrated high clinical practicability in helping patients systematically understand the self-management framework after liver transplantation,promoting doctor-patient communication,and enhancing the initiative of self-management.Conclusion The question prompt list of postoperative self-management for adult liver transplant recipients established in this study is scientific,reliable,and practical,which is helpful for patients to obtain information about self-management from medical staff.

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 analyze the correlation of neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and systemic immune-inflammatory index(SII)with short-term outcome and long-term prognosis in patients with advanced non-small cell lung cancer(NSCLC).Methods A retrospective study was conducted.A total of 215NSCLC patients who received a complete 4-cycle chemotherapy combined with immunotherapy or chemotherapy alone in the Department of Respiratory and Critical Care Medicine,Affiliated Hospital of Xuzhou Medical University from January 2021 to January 2023 were selected as the research subjects.The patients were divided into remission group(n=97)and non-remission group(n=118)based on the efficacy of the treatments,and the differences in NLR,PLR,SII,and decline rate of each index were compared between the two groups.NLR,PLR,SII and decline rate before and after treatment were grouped by the best cut-off value or median,and the differences in progression-free survival and overall survival were analyzed by each index group.Results NLR and PLR in the remission group before each cycle of treatment were signifi-cantly lower than those in the non-remission group,and SII in the remission group before cycles 2nd,3rd,and 4th of treatment were sig-nificantly lower than those in the non-remission group(P＜0.05);From initial treatment to before the fourth treatment cycle,NLR and SII decline rates in the remission group were significantly higher than those in the non-remission group(P＜0.05);the tumor stage,NLR before cycle 4th of treatment were independent influencing factors of short-term efficacy in patients with advanced NSCLC(P＜0.05);patients with low NLR,PLR,SII and higher rates of decline in NLR and SII before cycle 4th treatment had longer progression-free survival and overall survival(P＜0.05).Conclusion Tumor stage and post-treatment NLR are significantly correlated with the short-term outcomes of patients with advanced NSCLC,and high post-treatment NLR often suggests a poorer response to treatment.The prognosis of advanced NSCLC patients with higher NLR decline rate and higher SII decline rate after treatment is better.

Emerging evidence suggests that ferroptosis,an iron-dependent form of regulated cell death,plays a criti-cal role in the genesis of liver fibrosis through inducing hepatic stellate cell(HSC)ferroptosis to inhibit liver fibrosis or inducing hepatic ferroptosis to potentiates liver fibrosis.Pharmacologically targeting at ferroptosis with its inducers can slow down the progression of liver fibrosis in vitro and in vivo model.This review suggests that pharmacological in-duction of HSC ferroptosis might be used as a potential novel targeted therapy for the treatment of liver fibrosis.

Objective:To investigate serum vitamin A and vitamin D status in children aged 2-<7 years in 20 cities in China.Methods:A cross-sectional study was conducted. A total of 2 924 healthy children aged 2-<7 years were recruited from September 2018 to September 2019 from 20 cities in China, categorized by age groups of 2-<3 years, 3-<5 years, and 5-<7 years. The demographic and economic characteristics and health-related information of the enrolled children were investigated. Body weight and height were measured by professional staff members. The serum vitamin A and vitamin D levels were detected by high-performance liquid chromatography-tandem mass spectrometry. Chi-square test and Logistic regression were applied to analyze the association between vitamin A and vitamin D deficiency and insufficiency as well as their underlying impact factors.Results:The age of the 2 924 enrolled children was 4.33 (3.42, 5.17) years. There were 1 726 males (59.03%) and 1 198 females (40.97%). The prevalences of vitamin A and vitamin D deficiency in enrolled children were 2.19% (64/2 924) and 3.52% (103/2 924), respectively, and the insufficiency rates were 29.27% (856/2 924) and 22.20% (649/2 924), respectively. Children with both vitamin A and vitamin D deficiencies or insufficiencies were found in 10.50% (307/2 924) of cases. Both vitamin A ( χ2=7.91 and 8.06, both P=0.005) and vitamin D ( χ2=71.35 and 115.10, both P<0.001) insufficiency rates were higher in children aged 3-<5 and 5-<7 years than those in children aged 2-<3 years. Vitamin A and vitamin D supplementation in the last 3 months was a protective factor for vitamin A and D deficiency and insufficiency, respectively ( OR=0.68 and 0.22, 95% CI 0.49-0.95 and 0.13-0.40, both P<0.05). The rates of vitamin A and D insufficiency was higher in children with annual household incomes <60 000 RMB than in those with annual household incomes ≥60 000 RMB ( χ2=34.11 and 10.43, both P<0.01). Northwest and Southwest had the highest rates of vitamin A and vitamin D insufficiency in children aged 2-<7 yeas, respectively ( χ2=93.22 and 202.54, both P<0.001). Conclusions:Among 20 cities in China, children aged 2-<7 years experience high rates of vitamin A and vitamin D insufficiency, which are affected by age, family economic level, vitamin A and vitamin D supplementation, and regional economic level. The current results suggest that high level of attention should be paid to vitamin A and vitamin D nutritional status of preschool children.

Objective:To explore the efficacy and safety of domestic bortezomib in combination with lenalidomide and dexamethasone in the treatment of newly diagnosed multiple myeloma (NDMM) .Methods:This multicenter, prospective, single-arm clinical study included 126 patients with NDMM admitted to seven hospitals between December 2019 and January 2022. All patients received domestic bortezomib in combination with lenalidomide and dexamethasone (BLD regimen), and the efficacy, prognostic factors, and safety were analyzed.Results:Among the 126 patients with NDMM, 118 completed four cycles of treatment, with an overall response rate (ORR) of 93.22% (110/118) and a ≥very good partial response (VGPR) rate of 68.64% (81/118). Ultimately, 114 patients completed at least eight cycles of treatment, with an ORR of 92.98% (106/114) and a ≥VGPR rate of 77.19% (88/114). Eighteen patients underwent autologous hematopoietic stem cell transplantation after completing 6-8 cycles of the BLD regimen, with an ORR of 100% (18/18) and a ≥VGPR rate of 88.9% (16/18). The proportion of patients achieving ≥VGPR increased with the treatment duration, and factors such as staging and age did not significantly affect efficacy. Single-factor analysis showed that R2-ISS stage Ⅲ/Ⅳ, blood calcium >2.27 mmol/L, and failure to achieve VGPR after six cycles were adverse prognostic factors for progression-free survival (PFS) ( P<0.05), whereas failure to achieve VGPR after six cycles was an adverse prognostic factor for overall survival (OS) ( P<0.001). Multifactor analysis demonstrated that failure to achieve VGPR after six cycles is an independent adverse prognostic factor for PFS ( P=0.002). The incidence of hematologic adverse reactions was 16.7% (19/114), and nonhematologic adverse reactions were mainly mild to moderate, with no significant cardiac or renal adverse reactions observed. Conclusion:The BLD regimen is effective in treating NDMM, in which patients with high-risk genetic features are still achieving a high ≥VGPR rate, and the overall safety is good.
