OBJECTIVE To investigate the effects of evolocumab combined with atorvastatin on post-percutaneous coronary intervention （PCI） efficacy and coronary microcirculation in patients with acute ST-segment elevation myocardial infarction （STEMI）. METHODS This retrospective cohort study included 194 hospitalized patients with acute STEMI who underwent PCI in the First Affiliated Hospital of Nanyang Medical College from Jan. 2022 to Dec. 2024. The patients were divided into control group （100 cases） and combination therapy group （94 cases） according to the different therapy plans. The control group was given Atorvastatin calcium tablets orally， at a dose of 20 mg， once a day. On the basis of the control group， the combination therapy group received an initial injection of Evolocumab injection 140 mg within 24 hours after PCI， followed by subsequent injections every 2 weeks. Both groups received continuous treatment for at least 30 days. Blood lipid indicators [total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol]， inflammation indicators [C-reactive protein （CRP） and interleukin-6 （IL-6）]， vascular Δ 基金项目河南省医学科技攻关计划项目（No.LHGJ20230971） endothelial function and microcirculation indicators [fibrinogen， ankle-brachial index （ABI） and nitric oxide （NO）]， cardiac function indicators [left ventricular ejection （LVEF）， left ventricular end-diastolic diameter and left ventricular end-systolic diameter] before treatment and after 30 days of treatment， as well as the occurrence of adverse reactions during the treatment， were compared between the two groups. RESULTS Before treatment， there were no statistically significant differences in the levels of the indicators of blood lipid， inflammation， vascular endothelial function and microcirculation， and cardiac function between the two groups （P＞0.05）. After 30 days of treatment， the levels of TC， TG， LDL-C， CRP， IL-6 and fibrinogen in both groups were significantly reduced compared to those before treatment within the same group. The levels of NO and LVEF in both groups， as well as ABI in the combination therapy group， were significantly elevated compared to those before treatment within the same group. Moreover， the improvements in the levels of TC， LDL-C， CRP， IL-6， fibrinogen and NO in the combination therapy group were more pronounced than those in the control group during the same period （P＜0.05）. There were no statistically significant differences in the incidence of liver function impairment， gastrointestinal adverse reactions， or the overall incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS Compared with atorvastatin alone， evolocumab combined with atorvastatin more effectively reduces the blood lipid levels， improves the inflammatory status， vascular endothelial function and coronary microcirculation in patients with acute STEMI after PCI， while the safety is comparable to that of atorvastatin alone.

Liver transplantation is one of the main treatments of early hepatocellular carcinoma (HCC). The recurrence of HCC after liver transplantation severely affects the long-term survival rate of the recipients. Targeted therapy and immunotherapy play a critical role in HCC downstaging, preventing disease progression, reducing recurrence rate, prolonging the survival and improving the quality of life. However, no consensus has been reached on the application of targeted therapy and immunotherapy in recipients undergoing liver transplantation for HCC, including indications, timing and dosage. In this article, clinical research progresses on the indications and timing of targeted therapy and immunotherapy before and after liver transplantation for HCC were reviewed, aiming to provide reference for prolonging the survival of recipients after liver transplantation for HCC.

Objective:To screen out and analyze the key genes of follicular lymphoma (FL) according to transcriptome data in Gene Expression Omnibus (GEO) database.Methods:Transcriptome datasets GSE32018 and GSE55267 were collected by using GEO database. R software was used for variance analysis to screen differentially expressed genes. FunRich 3.13 software was used to analyze common differential genes. The biological processes and pathways were analyzed with Cytoscape 3.7.2 software to screen potential genes related to the pathogenesis of FL. By analyzing clinical data from Oncomine database for survival analysis, the screened differential genes were verified.Results:A total of 141 up-regulated genes and 199 down-regulated genes were identified by differentially analyzing GSE32018 and GSE55267 datasets. Finally, 12 key genes including CXCL8, KRT19, CYCS, CDKN3, SFN, RRM2, FN1, APOE, CXCL12, VWF, GATA3 and TIMP1 were screened out; CYCS, CXCL8 and CXCL12 were closely related with the early survival rate of patients. Overexpression of CXCL12 and low expression of CYCS were found to be associated with poor prognosis of FL patients. CXCL8 expression was decreased in lymphoma tissues, but the relatively high expression of CXCL8 in survival analysis showed shortened overall survival, which might be related to the early development of FL. GO, KEGG and Reactome pathways were screened out including GO: 0001892, KEGG: 04115, R-HSA: 2559582, GO: 0060968, R-HSA: 6785807, GO: 0043627, GO: 0001936 and GO: 0043062.Conclusion:The selected genes CYCS, CXCL8 and CXCL12 may provide more effective biomarkers for the treatment of FL.

Parthenogenetic embryonic stem cells (pESCs) derived from bi-maternal genomes do not have competency of tetraploid complementation, due to lacking of paternal imprinting genes. To make pESCs possess fully development potentials and similar pluripotency to zygote-derived ESCs, we knocked out one allelic gene of the two essential maternal imprinting genes (H19 and IG) in their differentially methylated regions (DMR) via CRISPR/Cas9 system and obtained double knock out (DKO) pESCs. Maternal pESCs had similar morphology, expression levels of pluripotent makers and in vitro neural differentiation potentials to zygotes-derived ESCs. Besides that, DKO pESCs could contribute to full-term fetuses through tetraploid complementation, proving that they held fully development potentials. Derivation of DKO pESCs provided a type of major histocompatibility complex (MHC) matched pluripotent stem cells, which would benefit research in regenerative medicine.
