BACKGROUND: Angiotensin receptor neprilysin inhibitors (ARNIs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers (BBs), and mineralocorticoid receptor antagonists (MRAs) are the cornerstones in treating heart failure with reduced ejection fraction (HFrEF). Sodium-glucose cotransporter 2 inhibitors (SGLT-2is) are included in HFrEF treatment guidelines. However, the effect of SGLT-2i and the five drugs on HFrEF have not yet been systematically evaluated. METHODS: PubMed, Embase, and the Cochrane Library were searched for randomized controlled trials (RCTs) from inception dates to September 23, 2022. Additional trials from previous relevant reviews and references were also included. The primary outcomes were changes in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter/dimension (LVEDD), left ventricular end-systolic diameter/dimension (LVESD), left ventricular end-diastolic volume (LVEDV), and left ventricular end-systolic volume (LVESV), left ventricular end-systolic volume index (LVESVI), and left ventricular end-diastolic volume index (LVEDVI). Secondary outcomes were New York Heart Association (NYHA) class, 6-min walking distance (6MWD), B-type natriuretic peptide (BNP) level, and N-terminal pro-BNP (NT-proBNP) level. The effect sizes were presented as the mean difference (MD) with 95% confidence interval (CI). RESULTS: We included 68 RCTs involving 16,425 patients. Compared with placebo, ARNI + BB + MRA + SGLT-2i was the most effective combination to improve LVEF (15.63%, 95% CI: 9.91% to 21.68%). ARNI + BB + MRA + SGLT-2i (5.83%, 95% CI: 0.53% to 11.14%) and ARNI + BB + MRA (3.83%, 95% CI: 0.72% to 6.90%) were superior to the traditional golden triangle ACEI + BB + MRA in improving LVEF. ACEI + BB + MRA + SGLT-2i was better than ACEI + BB + MRA (-8.05 mL/m 2 , 95% CI: -14.88 to -1.23 mL/m 2 ) and ACEI + BB + SGLT-2i (-18.94 mL/m 2 , 95% CI: -36.97 to -0.61 mL/m 2 ) in improving LVEDVI. ACEI + BB + MRA + SGLT-2i (-3254.21 pg/mL, 95% CI: -6242.19 to -560.47 pg/mL) was superior to ARB + BB + MRA in reducing NT-proBNP. CONCLUSIONS: Adding SGLT-2i to ARNI/ACEI + BB + MRA is beneficial for reversing cardiac remodeling. The new quadruple drug "ARNI + BB + MRA + SGLT-2i" is superior to the golden triangle "ACEI + BB + MRA" in improving LVEF. REGISTRATION PROSPERO; No. CRD42022354792.

By analyzing the influencing factors for bone health and bone metabolism during the perioperative period of liver transplantation， this article emphasizes the importance of a comprehensive assessment of bone health and necessary interventions at this stage， with an aim to reduce the risk of postoperative complications and improve the long-term prognosis of patients. A deeper exploration of the association between hepatic osteodystrophy and the prognosis of liver transplantation can help to reveal the key influencing factors for postoperative outcomes， thus providing a theoretical basis for optimizing postoperative management strategies. Furthermore， advances in this research field will offer new insights into the treatment of patients receiving liver transplantation， and it is expected to further improve quality of life and long-term survival rate.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

Objective To investigate the effect of altered oxidative stress system on liver function after partial splenic embolization(PSE).Methods Twenty-nine patients with liver cirrhosis and hypersplenism who received PSE were selected.Peripheral venous blood was drawn from the patients before and at 1 week,1 month,and 3 months after PSE,and the indexes of oxidative stress system factors including malondialdehyde(MDA),superoxide dismutase(SOD),advanced oxidiation protein products(AOPPs),and gluta-thione peroxidase(GSH-Px)were detected,as well as liver function indexes.Results There were positive correlation between SOD activity and total bilirubin(TBil)and model for end-stage liver disease(MELD)scores at 1 week postoperatively(TBil:r=0.725,P＜0.05;MELD:r=0.764,P＜0.05).There was positive correlation between GSH-Px activity and alanine aminotransferase(ALT)at 1 month postoperatively(r=0.777,P＜0.05),however,the AOPPs was negatively correlated with ALT and aspartate aminotransferase(AST)at 3 months postoperatively(ALT:r--0.900,P＜0.05;AST:r=-0.957,P＜0.05).Conclusion PSE can improve the body oxidative stress system and enhance the body's antioxidant response,and then improve the liver function.

Pancreatobiliary maljunction(PBM)represents a congenital anatomical abnormality of the pancreaticobiliary ductal system,frequently predisposing individuals to recurrent cholangitis and pancreatitis.Accumulating evidence indicates that PBM is a precancerous lesion,and PBM plays an important role in the development and progression of gallbladder cancer(GBC).GBC arising from PBM is designated as PBM-associated GBC.Consequently,early diagnosis and treatment of PBM is paramount in mitigating the risk of GBC.This review outlined the epidemiology and advancements in the diagnosis and management of PBM,along with the clinical features,underlying mechanisms,and therapeutic progressions pertaining to PBM-associated GBC,in order to underscore the clinical significance of early intervention in PBM,so as to reduce the incidence of PBM-associated GBC.

Objective:To analyze the clinicopathological features and differential diagnosis of large B-cell lymphoma with IRF4 rearrangement, aiming enhance its recognition and prevent misdiagnosis.Methods:The clinicopathological features, immunophenotype, and fluorescence in situ hybridization (FISH) results of six cases diagnosed with IRF4 rearrangement-positive B-cell lymphoma at the Affiliated Hospital of Xuzhou Medical University from 2015 to 2023 were retrospectively analyzed. Additionally, a comprehensive review of the literature was conducted.Results:Six patients with IRF4 rearrangement-positive large B-cell lymphoma were included. Patients 1 to 5 included three males and two females with a median age of 19 years ranging from 11 to 34 years. Four patients presented with head and neck lesions, while the other one had a breast nodule; all were in clinical Ann Arbor stages I to Ⅱ. Morphologically, entirely diffuse pattern was present in two cases, purely follicular pattern in one case, and diffuse and follicular patterns in other two cases. The tumor cells, predominantly centroblasts mixed with some irregular centrocytes, were of medium to large size, with a starry sky appearance observed in two cases. Immunophenotyping revealed all cases were positive for bcl-6 and MUM1, with a Ki-67 index ranging from 70% to 90%, and CD10 was positive in two cases. IRF4 rearrangement was confirmed in all cases by FISH analysis, with dual IRF4/bcl-6 rearrangements identified in two cases, leading to a diagnosis of LBCL-IRF4. Case 6, a 39-year-old female with a tonsillar mass and classified as clinical Ann Arbor stage Ⅳ, displayed predominantly diffuse large B-cell lymphoma (DLBCL) morphology with 20% high-grade follicular lymphoma characteristics. Immunohistochemistry showed negative CD10 and positive bcl-6/MUM1, with a Ki-67 index of approximately 80%. Triple rearrangements of IRF4/bcl-2/bcl-6 were identified by FISH, leading to a diagnosis of DLBCL with 20% follicular lymphoma (FL). All six patients achieved complete remission after treatment, with no progression or relapse during a follow-up period of 31-100 months.Conclusions:Large B-cell lymphoma with IRF4 rearrangement is a rare entity with pathological features that overlap with those of FL and DLBCL. While IRF4 rearrangement is necessary for diagnosing LBCL-IRF4, it is not specific and requires differentiation from other aggressive B-cell lymphomas with IRF4 rearrangement.

Objective:To investigate the efficacy of liver wedge resection and liver Ⅳb and Ⅴ segmentectomy for T2 gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 168 patients who underwent radical resection of T2 GBC in The First Affiliated Hospital of Xi′an Jiaotong University from January 2011 to December 2021 were collected. There were 59 males and 109 females, aged (65±10)years. Of 168 patients, there were 112 cases in T2a stage and 56 cases in T2b stage. Of 112 patients in T2a stage, 73 cases underwent liver wedge resection and 39 cases underwent liver Ⅳb and Ⅴ segmentectomy. Of 56 patients in T2b stage, 27 cases underwent liver wedge resection and 29 cases underwent liver Ⅳb and Ⅴ segmen-tectomy. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX proportional risk model was used for univariate and multivariate analyses. Results:(1) Clinical data analysis of patients undergoing different extent of hepatic resection for T2 GBC. There was no significant difference in gender, age, cholecystoli-thiasis, preoperative total bilirubin, carcinoembryonic antigen, CA19-9, CA125, incidental GBC, perineural invasion, microvascular invasion, pathological differentiation, histopathological subtypes, N staging, TNM staging between patients with T2a and T2b GBC who underwent different extent of hepatic resection ( P>0.05). (2) Prognostic analysis of T2 GBC patients undergoing different extent of hepatic resection. The 1-, 3- and 5-year cumulative disease-free survival rates of T2 GBC patients undergoing liver wedge resection were 78.0%, 60.1% and 51.4%, respectively, versus 86.8%, 80.0% and 68.0% of T2 GBC patients undergoing liver Ⅳb and Ⅴ segmentectomy, showing a significant difference between them ( χ2 =5.205, P<0.05). The 1-, 3-, and 5-year cumulative overall survival rates of T2 GBC patients undergoing liver wedge resection were 85.0%, 62.5%, and 55.1%, respectively, versus 92.6%, 81.6%, and 68.8% for T2 GBC patients undergoing liver Ⅳb and Ⅴ segmentectomy, showing a significant difference in cumulative overall survival rate between them ( χ2=4.351, P<0.05). The 1-, 3-, and 5-year cumulative disease-free survival rates of T2b GBC patients undergoing liver wedge resection were 70.4%, 45.9% and 39.2%, respectively, versus 89.7%, 71.3% and 54.0% of T2b GBC patients undergoing liver Ⅳb and Ⅴ segmentectomy, showing a significant difference between them ( χ2=5.047, P<0.05). The 1-, 3-, and 5-year cumulative overall survival rates of T2b GBC patients undergoing liver wedge resection were 81.5%, 53.2%, and 41.0%, respectively, versus 89.7%, 77.0%, and 60.7% of T2b GBC patients undergoing liver Ⅳb and Ⅴ segmentectomy, showing no significant difference in cumulative overall survival rate between them ( χ2=4.014, P<0.05). (3) Analysis of factors influencing prognosis of patients undergoing radical resection for T2 GBC. Results of multivariate analysis showed that CA19-9>39.0 U/mL, perineural invasion, N1 and N2 stage were independent risk factors influencing disease-free survival time of patients undergoing radical resection for T2 GBC ( hazard ratio=2.736, 3.496, 2.638, 17.440, 95% confidence interval as 1.195-6.266, 1.213-10.073, 1.429-4.869, 8.362-36.374, P<0.05). Liver Ⅳb and Ⅴ segmentectomy was an independent protective factor influencing disease-free survival time of patients undergoing radical resection for T2 GBC ( hazard ratio=0.418, 95% confidence interval as 0.230-0.759, P<0.05). CA19-9 >39.0 U/mL, perineural invasion, ⅡB stage, ⅢB stage and ⅣB stage of TNM staging were independent risk factors influencing overall survival time of patients undergoing radical resection for T2 GBC ( hazard ratio=2.740, 3.210, 2.037, 3.439, 24.466, 95% confidence interval as 1.127-6.664, 1.049-9.819, 1.004-4.125, 1.730-6.846, 10.733-55.842, P<0.05). Liver Ⅳb and Ⅴ segmentectomy was an independent protective factor influencing overall survival time of patients undergoing radical resec-tion for T2 GBC ( hazard ratio=0.476, 95% confidence interval as 0.261-0.867, P<0.05). (4) Analysis of postoperative complications in patients undergoing different extent of hepatic resection for T2 GBC. There was no significant difference in postoperative complications of patients with T2a and T2b GBC undergoing liver wedge resection or liver Ⅳb and Ⅴ segmentectomy ( P>0.05). Conclusions:Compared to liver wedge resection, liver Ⅳb and Ⅴ segmentectomy can effectively prolong the disease-free survival overall survival time of T2b GBC patients. There is no significant difference in the major complications. Liver Ⅳb and Ⅴ segmentectomy is an independent protective factor for prognosis of patients undergoing radical resection for T2 GBC.

Objective:Percutaneous coronary intervention(PCI)is one of the most important treatments for coronary artery disease(CAD).However,in-stent restenosis(ISR)after PCI is a serious complication without effective measures for prevention and treatment.This study aims to investigate the Ras-related protein 1A(Rap1A)level in ISR patients and in the tumor necrosis factor-α(TNF-α)-induced inflammatory injury model of human umbilical vein endothelial cells(HUVECs),to explore the role of Rap1A in regulating TNF-α-induced inflammation in HUVECs and to provide a new potential target for ISR prevention and treatment. Methods:A total of 60 CAD patients,who underwent PCI between December 2020 and July 2022 from the Department of Cardiovascular Medicine of Xiangya Hospital,Central South University,and re-examined coronary angiography(CAG)1 year after the operation,were included.After admission,27 patients were diagnosed with ISR and 33 patients were diagnosed with non-in-stent restenosis(non-ISR)according to the CAG.Clinical data were collected,and the plasma Rap1A level was determined by enzyme linked immunosorbent assay(ELISA).In cell experiments,an inflammatory injury model was established with TNF-α treatment(10 ng/mL,24 h)in HUVECs.The mRNA and protein expression levels of Rap1A,interlukin-6(IL-6),and vascular cell adhesion molecule-1(VCAM-1)were measured by real-time reverse transcription PCR and Western blotting.Small interfering RNA(siRNA)was used to explore the role of Rap1A in regulating TNF-α-induced inflammation in HUVECs. Results:Compared with the non-ISR patients,a higher proportion of ISR patients had a history of smoking(P=0.005)and diabetes(P=0.028),and higher levels of glycosylated hemoglobin(HbA1c)(P=0.012),low-density lipoprotein cholesterol(LDL-c)(P=0.014),and hypersensitive C-reactive protein(hs-CRP)(P=0.027).The remaining projects did not show significant differences(all P＞0.05).The plasma level of Rap1A in the ISR group was significantly higher than that in the non-ISR group[942.14(873.28 to 1 133.81)μg/mL vs 886.93(812.61 to 930.98)μg/mL;P=0.004].Diabetes,LDL-c,and Rap1A were risk factors for ISR by univariate logistic regression analysis(all P＜0.05).The mRNA and protein expression levels of inflammatory factors IL-6 and VCAM-1 were increased in HUVECs after 10 ng/mL TNF-α treatment for 24 h compared with the control group(all P＜0.05),while the mRNA and protein levels of Rap1A were increased(both P＜0.05).After inhibition of Rap1A in HUVECs,the mRNA and protein expression levels of IL-6 and VCAM-1 were significantly decreased(all P＜0.05). Conclusion:The plasma Rap1A level was significantly elevated in patients with ISR,suggesting that Rap1A may be a potential biomarker for predicting ISR.In the TNF-α-induced HUVECs inflammatory injury model,the expression level of Rap1A was increased.The level of TNF-α-induced endothelial cell inflammation was decreased after inhibition of Rap1A expression,suggesting that Rap1A may be a potential target for the treatment of endothelial cell inflammation in ISR.

Objective: To explore the growth characteristics of rat calvaria by detecting the calvaria of SD rats in different periods. Methods: The calvaria of SD rats at 1 , 4 , 7 , 10 , and 12 weeks from the same littermate were selected (3 rats per week) . Real⁃time PCR and Western blot techniques were used to detect the expression of focal adhesion kinase ( FAK) Ⅳ phosphatidylinositol 3 kinase/protein kinase B ( PI3K/AKT ) signal pathway in the calvaria , and the role of FAK⁃PI3K/AKT in the growth and development of the calvaria was analyzed by correlation. Results: The increase of brain volume and the thickness of calvaria increased synchronously , the expression of FAK was positively correlated with the changes of meridians , and the expression of FAK was positively correlated with the expression of PI3K/AKT. Conclusion The expression of FAK is related to the growth and development of rat skull. FAK plays a role in calvaria by activating PI3K/AKT signal pathway. FAK may be used as a marker of rapid skull growth and development , which provides a basic theoretical basis for the timing of clinical skull defect repair and treatment.
