Objective:To investigate the diagnostic value of plasma cytokines such as interleukin (IL)-2, IL-6 and interferon (IFN)-γ in non-Hodgkin lymphoma (NHL).Methods:A retrospective case-control study was conducted. A total of 48 NHL patients admitted to the Second Affiliated Hospital of Xuzhou Medical University between January 2020 and December 2022 were selected as NHL group, and another 34 healthy people who underwent physical examimation during the same period were selected as the healthy control group. The levels of IL-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF) - α and IFN-γ in the plasma of patients at first admission and healthy subjects during physical examination were detected by using flow cytometry. The differences in general data and all cytokines levels of both groups were compared. The collinearity stepwise screening was made in 7 cytokines levels, and the screened variables were included in multivariate binary logistic regression model. Plasma cytokines with independent effects on the pathogenesis of NHL were screened. Taking local biopsy, histopathological examination or immunohistochemical examination as the gold standard, the receiver operating characteristic (ROC) curves of individual and combined diagnosis of NHL based on the selected cytokines were drawn to judge the diagnostic effect of all indicators on NHL.Results:There were 32 males (66.7%) and 16 females (33.3%) in NHL group, with the median age [ M ( Q1, Q3)] of 56.50 (45.75, 67.50) years; there were 28 males (82.4%) and 6 females (17.6%) in the healthy control group, with the median age of 52.00 (47.50, 55.50) years. There were no statistically significant differences in age and gender composition between the 2 groups (all P > 0.05). The levels of IL-2 [1.44 (1.36, 1.85) pg/ml vs. 1.19 (0.86, 1.68) pg/ml] and TNF-α [3.46 (2.68, 4.06) pg/ml vs. 2.23 (1.52, 3.46) pg/ml] in NHL group were higher than those in the healthy control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in IL-4, IL-6, IL-10, IL-17, IFN-γ levels (all P > 0.05). According to collinear stepwise screening of independent variables, IL-4 and TNF-α were excluded from 7 cytokines, and the other 5 cytokines were included in multivariate logistic regression model, and the result showed that the decreased level of IL-2 ( OR = 0.20, 95% CI: 0.08-0.53, P = 0.001) and the increased levels of IL-6 ( OR = 1.18, 95% CI: 1.04-1.33, P = 0.009) and IFN-γ ( OR = 1.26, 95% CI: 1.08-1.46, P = 0.003) were independent risk factors for the onset of NHL. The results showed that the area under the curve of IL-2, IL-6, IFN-γ and the combination of 3 indexes for the diagnosis of NHL was 0.760 (95% CI: 0.651-0.870), 0.595 (95% CI: 0.468-0.722), 0.508 (95% CI: 0.373-0.642), 0.847 (95% CI: 0.763-0.930), and the optimal cut-off value of the combination of 3 indexes was 0.730 which was calculated by logistic regression model formula; the corresponding sensitivity and specificity were 70.2% and 94.1%, respectively. Conclusions:The decreased level of IL-2 and increased levels of IL-6 and IFN-γ at initial diagnosis are risk factors for the onset of NHL. The combined detection of the 3 indexes shows a good value in the diagnosis of NHL.

Objective:To investigate the relationship between retinoblastoma binding protein 1 (RB1) gene deletion and the prognosis of multiple myeloma (MM) patients, and the possible effect of renal insufficiency on it.Methods:A retrospective cohort study was conducted. The clinical data and follow-up information of MM patients who were treated in the Second Affiliated Hospital of Xuzhou Medical University and the Affiliated Hospital of Xuzhou Medical University from December 2020 to November 2023 were collected. According to the presence of RB1 gene deletion in bone marrow samples detected by fluorescence in situ hybridization (FISH), the patients were divided into the RB1 gene deletion group and the RB1 gene non-deletion group, and the clinicopathological characteristics and hematological index levels were compared between the two groups. Renal insufficiency was determined by renal function assessment indicator serum creatinine (Scr) >177 μmol/L. The Spearman test was used to analyze the relationship between the number of RB1 gene deletion positive cells and levels of Scr, hemoglobin and serum calcium in MM patients. The Kaplan-Meier method was used to analyze progression-free survival (PFS), and the Cox proportional hazards model was used to determine the influencing factors of PFS in all MM patients and RB1 gene deletion and non-deletion MM patients.Results:A total of 75 MM patients were enrolled, of whom 24 (32.0%) had RB1 gene deletion. There were no significant differences in gender, age ≥65 years old, bone destruction and lactate dehydrogenase level between the RB1 gene deletion and non-deletion groups (all P > 0.05). There were significant differences in the distributions of patients in each stage of MM International Staging System (ISS) and revised International Staging System (R-ISS) between the two groups, as well as in hemoglobin, serum calcium, Scr, β 2-microglobulin, serum albumin levels, and the proportion of bone marrow plasma cells (all P < 0.05). The number of RB1 gene deletion positive cells was positively correlated with Scr level ( r = 0.863, P = 0.016), but not with hemoglobin and serum calcium levels (both P > 0.05). The PFS of the RB1 gene non-deletion group was better than that of the RB1 gene deletion group (1-year PFS rate: 83.5% vs. 71.7%, 2-year PFS rate: 56.3% vs. 26.3%), and the difference was statistically significant ( P = 0.012). PFS in the non-renal insufficiency group was better than that in the renal insufficiency group (1-year PFS rate: 85.6% vs. 61.9%, 2-year PFS rate: 58.0% vs. 13.5%), and the difference was statistically significant ( P = 0.001). The PFS of patients without renal insufficiency in both the RB1 gene deletion and non-deletion groups was better than that in patients with renal insufficiency, and the differences were statistically significant (both P < 0.05). Multivariate Cox regression analysis showed that ISS stage Ⅲ was an independent risk factor for poor PFS in MM patients (stage Ⅲ vs. stage Ⅰ, HR = 11.317, 95% CI: 1.220-104.979, P = 0.033). Multivariate Cox regression analysis in RB1 gene deletion and non-deletion groups showed that ISS stage Ⅲ (stage Ⅲ vs. stageⅠ, HR = 4.166, 95% CI: 1.419-12.225, P = 0.009), R-ISS stage Ⅲ (stage Ⅲ vs. stage Ⅰ, HR = 3.800, 95% CI: 1.005-14.367, P = 0.049), serum calcium > 2.52 mmol/L (> 2.52 mmol/L vs. ≤2.52 mmol/L, HR = 2.398, 95% CI: 1.037-5.546, P = 0.041) and renal insufficiency (yes vs. no, HR = 2.363, 95% CI: 1.021-5.472, P = 0.045) were independent risk factors for poor PFS in RB1 gene non-deletion MM patients, and serum calcium >2.52 mmol/L (>2.52 mmol/L vs. ≤ 2.52 mmol/L, HR = 3.673, 95% CI: 1.160-11.627, P = 0.027) and renal insufficiency (yes vs. no, HR = 3.985, 95% CI: 1.220-13.016, P = 0.022) were independent risk factors for poor PFS in RB1 gene deletion MM patients. Conclusions:The PFS of MM patients with RB1 gene deletion is worse than that of patients without RB1 gene deletion, RB1 gene deletion may be related to renal insufficiency in MM patients, and the prognosis of MM patients with RB1 gene deletion and renal insufficiency may be worse.

Objective:To investigate the clinical features and therapeutic efficacy of patients with hereditary leiomyomatosis and renal cell carcinoma(RCC) syndrome-associated RCC (HLRCC-RCC) in China.Methods:The clinical data of 119 HLRCC-RCC patients with fumarate hydratase (FH) germline mutation confirmed by genetic diagnosis from 15 medical centers nationwide from January 2008 to December 2021 were retrospectively analyzed. Among them, 73 were male and 46 were female. The median age was 38(13, 74) years. The median tumor diameter was 6.5 (1.0, 20.5) cm. There were 38 cases (31.9%) in stage Ⅰ-Ⅱand 81 cases (68.1%) in stage Ⅲ-Ⅳ. In this group, only 11 of 119 HLRCC-RCC patients presented with skin smooth muscle tumors, and 44 of 46 female HLRCC-RCC patients had a history of uterine fibroids. The pathological characteristics, treatment methods, prognosis and survival of the patients were summarized.Results:A total of 86 patients underwent surgical treatment, including 70 cases of radical nephrectomy, 5 cases of partial nephrectomy, and 11 cases of reductive nephrectomy. The other 33 patients with newly diagnosed metastasis underwent renal puncture biopsy. The results of genetic testing showed that 94 patients had FH gene point mutation, 18 had FH gene insertion/deletion mutation, 4 had FH gene splicing mutation, 2 had FH gene large fragment deletion and 1 had FH gene copy number mutation. Immunohistochemical staining showed strong 2-succinocysteine (2-SC) positive and FH negative in 113 patients. A total of 102 patients received systematic treatment, including 44 newly diagnosed patients with metastasis and 58 patients with postoperative metastasis. Among them, 33 patients were treated with tyrosine kinase inhibitor (TKI) combined with immune checkpoint inhibitor (ICI), 8 patients were treated with bevacizumab combined with erlotinib, and 61 patients were treated with TKI monotherapy. Survival analysis showed that the median progression-free survival (PFS) of TKI combined with ICI was 18 (5, 38) months, and the median overall survival (OS) was not reached. The median PFS and OS were 12 (5, 14) months and 30 (10, 32) months in the bevacizumab combined with erlotinib treatment group, respectively. The median PFS and OS were 10 (3, 64) months and 44 (10, 74) months in the TKI monotherapy group, respectively. PFS ( P=0.009) and OS ( P=0.006) in TKI combined with ICI group were better than those in bevacizumab combined with erlotinib group. The median PFS ( P=0.003) and median OS ( P=0.028) in TKI combined with ICI group were better than those in TKI monotherapy group. Conclusions:HLRCC-RCC is rare but has a high degree of malignancy, poor prognosis and familial genetic characteristics. Immunohistochemical staining with strong positive 2-SC and negative FH can provide an important basis for clinical diagnosis. Genetic detection of FH gene germ line mutation can confirm the diagnosis. The preliminary study results confirmed that TKI combined with ICI had a good clinical effect, but it needs to be confirmed by the results of a large sample multi-center randomized controlled clinical study.

Angiopoietin-like 4(ANGPTL4)is one of the angiopoietin family members and plays a regulatory role in lipid metabolism,glucose homeostasis,inflammatory signal transduction,angiogenesis and vascular permeability.Inflammatory reaction in tumor microenvironment regulates tumor progression,and tumor angiogenesis plays a vital role in tumor growth and metastasis,so ANGPTL4 is closely related to tumor occurrence and development.Many studies have shown that ANGPTL4 plays an important regulatory role in tumor growth,anoikis resistance,tumor angiogenesis and tumor metastasis.This paper reviews the role of ANGPTL4 in tumor progression.

Objective To explore the clinical application value of second-generation dual-source CT combined with intelligent modulation and iterative reconstruction in emergency aortic dissection imaging.Methods A total of 40 emergency patients with clinical suspected aortic dissection were included in this study.Conventional scanning was performed in the control group,and large-pitch intelligent modulation and iterative reconstruction were performed in the test group.The mean CT value,mean noise,signal noise ratio(SNR),contrast noise ratio(CNR),effective dose,image quality and aortic root image quality were evaluated and analyzed.Results Totally 40 patients successfully completed CT aortic dissection imaging.There was no difference in image quality between the two groups (P＞ 0.05).The quality of aortic root images in the test group was better than that in the control group,and the difference was statistically significant(x2=22.556,P＜0.05).The mean CT value and mean noise of aorta in the control group were slightly higher than those in the test group.However,SNR and CNR in the test group were higher than those in the control group,and the difference was statistically significant (t =-21.042,-15.924,8.530,11.495,P＜0.05).The effective dose of the control group [(10.59±3.89)mSv] was significantly higher than that [(6.39±0.81) mSv] of the test group,the difference was statistically significant (t =-12.327,P＜0.05).Conclusions The combined intelligent modulation technique and iterative reconstruction technique with dual-source CT large pitch scanning can meet the requirements of image quality and reduce the effective dose,and can be used as a conventional imaging method for emergency CT of aortic dissection.

Objective To assess the value of cardiac magnetic resonance (CMR) imaging in left ventricular structure and function in patients with end stage renal disease (ESRD).Methods Twenty-five patients with ESRD and 10 healthy subjects underwent CMR.Left ventricular end diastolic volume(EDV),end-diastolic diameter(EDD),end-systolic volume(ESV),end-systolic diameter(ESD),stroke volume(SV),ejection fraction(EF),LVM and interventricular septum (IVS) thickness were measured and compared.The parameters from CMR and 2DTTE were compared.Results The EF in patients with ESRD was significantly lower than that in controls (P＜0.001),while ESV,ESD,IVS and LVM were respectively higher than these in controls (P＜0.05).There was no significant difference (P＞0.05) in ESV between CMR and 2DTTE,but EF of CMR was significantly higher than this of 2DTTE (P＜0.05).There was no significant difference (P =0.296) in left ventricular systolic functional category.Bland-Altman plots showed a good agreement between the two methods.Conclusion CMR is a helpful tool to assess left ventricular structure and function in patients with ESRD.
