Immune checkpoint blockade therapy has demonstrated remarkable efficacy in treating various malignancies; however, its clinical application remains challenged by low response rates and immune-related adverse events. Immunoglobulin superfamily member 11 (IGSF11), an inhibitory immune checkpoint molecule, serves as a specific ligand for the V-domain immunoglobulin suppressor of T cell activation (VISTA). Through the IGSF11/VISTA axis, it suppresses T cell function and represents a promising novel target for cancer immunotherapy. IGSF11 is widely expressed across multiple tumor types, though its regulatory mechanisms vary depending on the malignancy. Studies have confirmed that blocking the IGSF11-VISTA interaction or specifically inhibiting IGSF11 exerts antitumor effects. While IGSF11 is closely associated with patient prognosis, its prognostic significance differs among cancer types. This review systematically summarizes the structural characteristics of IGSF11, its regulatory mechanisms, interaction with VISTA, and functional role within the tumor microenvironment.

Objective:To observe the changes of small airway parameters in patients with coal workers' pneumoconiosis in different disease stages by high resolution computed tomography (HRCT) , and analyze the correlation between them and the severity of the disease.Methods:From June 2016 to June 2023, 25 healthy volunteers and 71 untreated patients with coal worker's pneumoconiosis in the Fifth People's Hospital of Ningxia were selected as the research objects. The clinical and imaging data of the patients were collected, and the disease stages were performed according to the dust exposure history and high-kilovolt chest X-ray. The patients were divided into 4 groups: control group (25 cases) , coal workers' pneumoconiosis stage Ⅰ group (17 cases) , coal workers' pneumoconiosis stage Ⅱ group (32 cases) and coal workers' pneumoconiosis stage Ⅲ group (22 cases) . Quantitative chest HRCT parameters of each group were collected, including the square root of wall area at 10 mm inner perimeter (AWT-Pi10, Pi10) , airway wall thickness, airway wall volume, airway wall area percentage of the whole lung and the 5th, 6th, 7th and 8th level airways, and low attenuation area percentage (LAA%) of the whole lung. Pulmonary function indicators were collected, including forced expiratory volume in 1 second (FEV 1) and the percentage of its projected value [FEV 1 (%pred) ], the ratio of FEV 1 to forced vital capacity (FEV 1/FVC) and the percentage of its projected value[FEV 1/FVC (%pred) ]. One-way ANOVA or Kruskal-Wallis H test and Spearman rank correlation were used to analyze the difference and correlation. Results:Compared with control group, FEV 1, FEV 1 (%pred) , FEV 1/FVC and FEV 1/FVC (%pred) in stage Ⅱ and Ⅲ coal workers' pneumoconiosis groups were lower ( P<0.05) . In addition, the FEV 1 and FEV 1 (%pred) of the stage Ⅲgroup were lower than those of the stageⅡ group ( P<0.05) , and the FEV 1/FVC and FEV 1/FVC (%pred) of the stage Ⅲgroup were lower than those of the stage Ⅰgroup ( P<0.05) . Compared with stage Ⅰ group, Pi10 in stage Ⅲ group were increased ( P < 0.05) at the 6th and 8th level airways, and airway wall thickness and airway wall volume in the 6th, 7th and 8th level airways of stage Ⅲgroup increased ( P<0.05) . Correlation analysis showed that all pulmonary function indexes were negatively correlated with Pi10 of whole lung and the 6th, 7th and 8th level airways ( P<0.05) , all pulmonary function indexes were negatively correlated with airway wall thickness of the 7th and 8th level airways ( P<0.05) , and FEV 1/FVC (%pred) was negatively correlated with airway wall volume of the 7th and 8th level airways ( P<0.05) . FEV 1, FEV 1 (%pred) , FEV 1/FVC (%pred) were negatively correlated with percentage of airway wall area of whole lung and the 6th, 7th and 8th level airways ( P<0.05) . Conclusion:The quantitative airway parameters of coal workers' pneumoconiosis based on HRCT are correlated with pulmonary function indexes, which can reflect the severity of coal workers' pneumoconiosis.

Objective:To investigate the clinical characteristics and independent risk factors of severe disease in patients with anti-nuclear matrix protein (NXP) 2 antibody-positive juvenile dermatomyositis (JDM).Methods:A retrospective cohort study was conducted, including 219 anti-NXP2 antibody-positive JDM patients admitted to 23 children′s hospitals across China from July 2011 to July 2023. Patients were classified into severe and non-severe groups based on classification criteria for severe dermatomyositis. Demographic characteristics, clinical manifestations, and laboratory parameters were compared between the 2 groups using independent sample t-test, Mann-Whitney U test, or χ2 test. Univariate and multivariate Logistic regression analyses were performed to identify risk factors for severe disease. The receiver operating characteristic curve was employed to calculate optimal cut-off values. Results:Among the 219 patients, 108 were male and 111 were female, with an age at onset of 6.3 (3.5, 9.4) years. The severe group comprised 69 patients, and the non-severe group 150 patients. The severe group had significantly higher rates of fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, as well as elevated levels of ferritin-to-albumin ratio (FAR), creatine kinase (CK), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) (all P<0.05). Multivariate analysis identified anti-Ro52 antibody positivity ( OR=13.26, 95% CI 1.37-128.29) and elevated FAR ( OR=1.90, 95% CI 1.09-2.31) as independent risk factors for severe anti-NXP2 antibody-positive JDM (both P<0.05). Receiver operating characteristic curve analysis revealed that a FAR cutoff value of 6.82 predicted severe disease with an area under the curve of 0.87 (95% CI 0.81-0.94, P<0.001), sensitivity of 0.85, and specificity of 0.70. All patients received glucocorticoid therapy, and the severe group received higher proportions of steroid pulse therapy, cyclophosphamide, mycophenolate mofetil, intravenous immunoglobulin, biologics, and adjuvant treatments compared to the non-severe group (all P<0.05). In terms of outcomes, 2 patients (2.9%) in the severe group died (due to neurological involvement and intestinal perforation, respectively), while the remaining patients achieved complete clinical response or remission. All patients in the non-severe group achieved remission. Conclusions:The primary clinical features of anti-NXP2 antibody-positive JDM included fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, and elevated levels of CK, AST, LDH, and FAR. Furthermore, anti-Ro52 antibody positivity and a FAR>6.82 were identified as independent risk factors.

The excessive inflammatory response after acute myocardial infarction (AMI) is detrimental to the repair of the infarcted myocardium, and anti-inflammatory interventions at the peak of inflammation have shown efficacy. Therefore, longitudinal monitoring of myocardial inflammatory evolution after AMI in vivo is important for individualized risk prediction, anti-inflammatory treatment strategies guidance and further prognosis improvement. 68Ga-pentixafor, a promising novel probe targeting C-X-C chemokine receptor 4 (CXCR4) on the surface of inflammatory cells, with no special preparation before imaging, allows in vivo visualization of the inflammation intensity, extent and evolution in the infarcted myocardium as well as the response of other related extra-cardiac organs. This review referred to its radiopharmaceutical characteristics, research status, explorations and limitations in AMI.

Objective:To investigate the postoperative renal function and oncologic outcomes of cystic renal cell carcinoma with partial nephrectomy,and to compared the single-center data on surgical out-comes with the Surveillance,Epidemiology,and End Results(SEER)database.Methods:This was a retrospective study that included the patients with cystic renal cell carcinoma who underwent partial ne-phrectomy in the Department of Urology,Peking University Third Hospital(PUTH)from 2010 to 2023.The clinical data and depicting baseline characteristics were collected.Renal dynamic imaging and the Chinese Coefficients for Chronic Kidney Disease Epidemiology Collaboration(C-CKD-EPI)formulae were used to calculate the estimated glomerular filtration rate(eGFR).The renal function curves over time were then plotted,and the patients were followed-up to record their survival status.Cases of cystic renal cell carcinoma in the SEER database between 2000 and 2020 were included,propensity score matching(PSM)was performed to balance the differences between SEER cohort and PUTH cohort,and the cancer-specific survival(CSS)curves for both groups were plotted and statistical differences were calcu-lated by the Kaplan-Meier method.Results:A total of 38 and 385 patients were included in the PUTH cohort and SEER cohort,respectively,and 31 and 72 patients were screened in each cohort after PSM.Of the baseline characteristics,only tumor size(P=0.042)was found to differ statistically between the two groups.There was no statistically significant difference between the two cohorts in terms of CSS after PSM(P=0.556).The median follow-up time in the SEER cohort was 112.5(65,152)months and a 10-year survival rate of 97.2％,while the PUTH cohort had a median follow-up of 57.0(20,1 172)months and a 10-year survival rate of 100.0％.There was no statistically significant difference between eGFR determined by preoperative renal dynamic imaging and the results of the C-CKD-EPI formulae based on creatinine estimation(P=0.073).There was a statistically significant difference in eGFR among the preoperative,short-term postoperative,and long-term postoperative(P＜0.001),which was characterized by the presence of a decline in renal function in the short-term postoperative period and the recovery of renal function in the long-term period.Conclusion:Partial nephrectomy for cystic renal cell carcinoma is safe and feasible with favorable renal function and oncologic outcomes.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.
