Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

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.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

Objective:To analyze the clinical outcomes of initial radioactive iodine 131I therapy (RIT) for patients with familial differentiated thyroid cancer (FDTC) and sporadic differentiated thyroid cancer (SDTC), along with their influencing factors. Methods:The clinical data of 120 FDTC and 480 SDTC patients who received RIT at the Department of Nuclear Medicine, Tianjin Medical University General Hospital from January 2016 to January 2022 were retrospectively analyzed. These patients, categorized into the FDTC and SDTC groups, were further divided into three subgroups based on their response to initial RIT: no evidence of disease (NED), biochemical persistence of disease (BPD), or structural/functional persistence of disease (S/FPD). For the NED subgroup, the disease-free survival (DFS) was analyzed. For the BPD and S/FPD subgroups, the progression-free survival (PFS) was investigated. Furthermore, risk factors for failure to reach the NED status were identified.Results:After initial RIT, 56 (46.7%), 50 (41.7%), 14 (11.6%) patients in the FDTC group reached the NED, BPD, and S/FPD statuses, respectively, while 284 (59.1%), 160 (33.3%), 36 (7.5%) and SDTC patients in the SDTC group were in the NED, BPD, and S/FPD statuses, respectively ( χ2 = 10.10, P = 0.013). The last follow-up revealed that 71 (59.1%), 36 (30.1%), 13 (10.8%) patients in the FDTC group were in the NED, BPD and S/FPD statuses, respectively, while 337 (70.2%), 114 (23.7%), 29 (6.1%) patients in the SDTC group reached the NED, BPD and S/FPD statuses, respectively ( χ2 = 8.99, P = 0.026). The F-NED and S-NED subgroups exhibited 5-year DFS rates of 92.4% and 97.4%, respectively, the F-BPD and S-BPD subgroups displayed 5-year PFS rates of 88.3% and 90.8%, respectively, while the F-S/FPD and S-S/FPD subgroups yielded in 5-year PFS rates of 78.2% and 79.6%, respectively. Univariate binary logistic regression analysis indicated that the maximum diameter of tumors, T stage, M stage, recurrence risk stratification, and postoperative stimulated thyroglobulin (p-sTg) were correlated with the achievement of the NED status ( χ2=6.37-13.10, P < 0.05). Multivariable binary logistic regression analysis showed that T stage and p-sTg were independent risk factors in the achievement of the NED status ( χ2=0.11-11.33, P < 0.05). Conclusions:The response to initial RIT assists in guiding the development of subsequent treatment and follow-up strategies for DTC patients. Given that the SDTC patients exhibited better outcomes than the FDTC patients, more alertness should be paid to the RIT for FDTC patients. For patients with higher p-sTg and T stage, the initial RIT dose and follow-up interval should be increased and reduced respectively as appropriate.

Objective:To explore the role and molecular mechanism of Shikonin(SKN) in inhibiting the growth of anaplastic thyroid carcinoma(ATC) cells.Methods:The effect of SKN on ferroptosis in ATC cell lines CAL-62 was detected by flow cytometry; the expression levels of NF-κB, ferroptosis-related genes glutathione peroxidase 4(GPX4) and selenoprotein thioredoxin reductase 1(TXNRD1), glucose metabolism-related genes pyruvate kinase isoform 2(PKM2) and glucose transporter protein 1(GLUT1) were detected by Western blotting; real-time fluorescence quantitative(qPCR) to detect changes in the expression levels of GPX4, PKM2 and GLUT1; reactive oxygen species(ROS) fluorescent probe to detect changes in intracellular ROS positivity; glucose and lactic acid assay kit to detect the levels of glucose, the raw material of glucose metabolism(GLU), and lactate(LD), the product of glucose metabolism; and establishment of a subcutaneous tumour model in BALB/c nude mice to analyse the inhibitory effect of SKN on ATC in vivo.Results:Compared to the control group, after SKN treatment, the protein expression levels of NF-κB, GPX4, TXNRD1, GLUT1, and PKM2 in CAL-62 cells decreased( P=0.004, P=0.012, P=0.043, P=0.001, P=0.018); the mRNA expression of GPX4, GLUT1, and PKM2 also decreased( P<0.001, P=0.029, P<0.001). Additionally, ROS production increased( P=0.041). After treatment with the ferroptosis inhibitor Liproxstatin-1(L-1), the proportion of cell death was reversed to a certain extent, and there was no statistically significant difference in cell death proportion after L-1 treatment. Intracellular ferroptosis occurred( P<0.001), with reduced levels of glutamate(GLU) uptake and lipid peroxidation(LD) generation( P<0.001). SKN inhibited ATC tumor growth in vivo( P=0.016). Conclusion:SKN promotes intracellular ferroptosis in ATC cells, inhibits glycolysis and glucose uptake, and suppresses ATC cell growth.

Objective:To investigate the mechanism of benzyl isothiocyanate(BITC) in the treatment of anaplastic thyroid cancer(ATC).Methods:Using network pharmacological analysis, key targets of BITC and ATC were screened, followed by GO and KEGG enrichment analysis. In order to validate the findings, AutoDock software was used to dock BITC and ATC key targets. BITC was applied to two ATC cell lines(8505C and CAL-62). Flow cytometry was used to analyze cell apoptosis. Autophagy inhibitors hydroxychloroquine sulfate(HCQ) and 3-methyladenine(3MA) were used in combination with BITC. Real-time quantitative PCR was conducted to detect the gene level of LC3B, while Western blotting was utilized to examine the expression of NF-κB, LC3B Ⅱ, Beclin-1, and Bcl-2. In animal experiments, a mouse tumor model was constructed using CAL-62 cells, treated with intraperitoneal injections of BITC(100 mg/kg) and normal saline respectively, administered every other day for a total of 21 days. Immunoblotting of tumor tissue was performed to detect the expression of LC3B Ⅱ, Bcl-2, Beclin-1, and NF-κB.Results:A total of 10 key targets with binding energies≤-4.0 kcal/mol were identified. KEGG analysis showed that these genes are mainly involved in NF-κB signaling pathway and apoptosis. BITC inhibited ATC cells with IC50 values of 27.56 μmol/L for 8505C and 28.30 μmol/L for CAL-62. The expression levels of NF-κB, Beclin-1, and Bcl-2 decreased, while LC3B Ⅱ and LC3B gene expression increased. Combining 3MA with BITC enhanced cell inhibition LC3B Ⅱ expression. HCQ increased LC3B Ⅱ expression without enhancing cell and viability inhibition. In the mouse tumor model, compared to the control group, the treatment group had higher LC3B Ⅱ and lower Bcl-2, Beclin-1, and NF-κB levels.Conclusion:BITC could inhibit the growth of ATC cells in vitro and in vivo, disrupt the autophagy degradation, and inhibit the NF-κB pathway.

Based on our previous work, the study herein designed and synthesized eight glycoconjugates of natural product harmine (14a-14h)by introducing a cyclohexylmethyloxyl group at its C7 position and coupling a methyl-2-amino-β-D-glucopyranoside to the N9 position through different lengths of alkyl chains.In vitro anti-tumor activity screening and structure-activity relationship studies showed that the antitumor activity of the conjugates increased with the lengthening of the alkyl chain in the linker.Compound 14h exhibited significantly better proliferative inhibitory activity against MDA-MB-231 breast cancer cells than harmine.As compared to harmine, the introduction of the carbohydrate moiety improved the water solubility of compound 14h and enhanced its tumor cell selectivity through the Warburg effect.Mechanism of action studies revealed that compound 14h induced apoptosis and G0/G1 cell cycle arrest in MDA-MB-231 cells, and inhibited tumor cell migration by interfering with epithelial-mesenchymal transition process.This study provides a new approach for the development of antitumor drugs based on harmine.

Objective:To study whether male was the risk factor for prognosis of patients with differentiated thyroid cancer (DTC) after 131I treatment based on propensity score matching (PSM) method. Methods:From April 2016 to January 2021, 1 677 patients (age: 11-84 (43.9±12.5) years) with DTC who underwent total thyroidectomy and received 131I treatment in Tianjin Medical University General Hospital were retrospectively enrolled and patients were divided into male group ( n=546) and female group ( n=1 131). The evaluation results of patients were divided into excellent response (ER), indeterminate response (IDR), biochemical incomplete response (BIR) and structural incomplete response (SIR). Among them, ER and IDR were divided into good prognosis group, and BIR and SIR were divided into poor prognosis group. The PSM method was adopted to process all data to reduce the influence of data bias and confounding variables. χ2 test was used for data analysis. Multivariate logistic regression was used to analyze the risk factors affecting prognosis, and ROC curve was used to analyze the relationship between stimulated thyroglobulin (sTg) level and poor prognosis. Results:Before PSM, the proportion of male patients with poor prognosis was significantly higher than that of female patients (21.2%(116/546) vs 14.0%(158/1 131); χ2=17.53, P=0.001). After PSM, there was no difference in the proportion of poor prognosis between male and female groups (19.9%(107/537) vs 15.6%(84/537); χ2=5.43, P=0.143). Multivariate logistic regression analysis showed that male (odds radio ( OR)=1.439 (95% CI: 1.016-2.038), P=0.040), high T stage(T3+ T4 stage)( OR=1.816 (95% CI: 1.273-2.590), P=0.001), N1b stage ( OR=1.766 (95% CI: 1.233-2.530), P=0.002), M1 stage ( OR=9.833 (95% CI: 3.190-30.309), P<0.001) and sTg level ( OR=1.035 (95% CI: 1.029-1.042), P<0.001) were risk factors for poor prognosis before PSM, while high T stage (T3+ T4 stage)( OR=1.870 (95% CI: 1.212-2.886), P=0.005), M1 stage ( OR=8.993 (95% CI: 2.434-33.225), P=0.001), sTg level ( OR=1.040 (95% CI: 1.030-1.049), P<0.001) were still risk factors, and N1b stage ( OR=1.459 (95% CI: 0.938-2.270), P=0.094), male ( OR=1.383 (95% CI: 0.912-2.096), P=0.127) were no longer risk factors for poor prognosis after PSM. ROC curve analysis showed that the cut-off value of sTg was 10.25 μg/L, with the sensitivity of 81.0%(222/274) and the specificity of 84.2%(1 181/1 403). Conclusions:After reduction of selection bias by PSM, male is no longer a risk factor for prognosis after 131I treatment of DTC. In addition, high T stage(T3+ T4 stage), M1 stage and sTg≥10.25 μg/L were risk factors for poor prognosis.

Objective:To explore the association between body mass index (BMI) and the incidence of thyroid nodules, the clinical characteristics and efficacy evaluation of differentiated thyroid cancer (DTC), respectively.Methods:Clinical data of 1 375 healthy people (1 031 males, 344 females, age: (43.5±10.6) years) who underwent routine physical examination (PE) and 1 450 patients (490 males, 960 females, age: (44.3±12.4) years) with medium-high risk DTC in Tianjin Medical University General Hospital from April 2016 to July 2020 were analyzed retrospectively. PE and DTC patients were classified into underweight group (BMI<18.5 kg/m 2), normal weight group (18.5≤BMI<24.0 kg/m 2), overweight group (24.0≤BMI<28.0 kg/m 2) and obesity group (BMI≥28.0 kg/m 2) respectively. χ2 test was employed to analyze the relation between BMI and thyroid nodules (with/without), BMI and clinical characteristics and efficacy evaluation of DTC, respectively. Logistic regression analysis was used to analyze the independent risk factors for the occurrence of thyroid nodules and the aggressiveness of DTC. Results:Among PE, there were 779 cases with nodules, and 596 cases without nodules. Comparing with those without nodules, more overweight and obese were found in PE cases with nodules (42.1%(328/779) vs 37.2%(222/596), 24.5%(191/779) vs 20.5%(122/596); χ2=13.42, P=0.004). Higher risk of developing thyroid nodules was related with older age and lower thyroid stimulating hormone (TSH) level (odds ratio ( OR): 1.044, 0.919, 95% CI: 1.029-1.060, 0.845-0.999; P<0.001, P=0.046). People with high-risk nodules were more likely to be obese than those with intermediate and lower risk nodules (5/15 vs 24.3% (186/764); χ2=21.11, P<0.001). Among 1 450 DTC patients, comparing with patients with normal weight, patients in the overweight and obesity groups were more likely to have central regional lymph node metastasis ( OR: 1.418, 1.427, 95% CI: 1.075-1.870, 1.044-1.952; P values: 0.013, 0.026), and patients in obese group were with greater risk of lesions being bilateral ( OR=0.696, 95% CI: 0.519-0.934; P=0.016). BMI was not related with the efficacy evaluation of DTC ( χ2=9.13, P=0.425). Conclusions:The incidence of thyroid nodules in people with high BMI is higher. DTC patients with high BMI may have more aggressive incidence. But BMI has no correlation with the efficacy evaluation of DTC patients after treatment.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.
