Objective To observe the effects of Angelica Sinensis Radix and Astragali Radix extract(ASR-AR)on HUVEC pyroptosis;To explore its mechanism of treating coronary microvascular disease.Methods HUVEC were divided into blank group,model group,MCC950 group,ASR-AR low-,medium-and high-dosage groups.After modeling and treatment with drug containing serum,cell viability was detected by CCK-8 method,and cell apoptosis was detected by flow cytometry,phalloidin staining was used to detect cytoskeletal morphology,immunofluorescence staining was used to detect the expressions of VEGF,eNOS,Ang-2,ROS,ET-1 and TXA2,ELISA was used to detect the contents of IL-1β and IL-18 in cell supernatant,Western blot was used to detect the expressions of NLRP3,ASC,Caspase-1 and GSDMD protein in cells.Results Compared with the blank group,the model group showed a decrease in HUVEC cell viability(P<0.01)and an increase in cell apoptosis rate(P<0.01),cellular microfilament structure was in disorder and knotting,the expressions of VEGF and eNOS decreased,and expressions of Ang-2,ROS,ET-1 and TXA2 increased,the contents of IL-1β and IL-18 in cell supernatant increased(P<0.01),and the expressions of NLRP3,ASC,Caspase-1 and GSDMD protein in cells increased(P<0.01).Compared with the model group,ASR-AR low-,medium-and high-dosage containing serum could increase cell viability(P<0.05),decrease cell apoptosis rate(P<0.05),improve cell microfilament structure,elevate VEGF and eNOS expressions,decrease Ang-2,ROS,ET-1,TXA2 expressions,reduce IL-1β and IL-18 contents in cell supernatant(P<0.05),and decrease NLRP3,ASC,Caspase-1 and GSDMD protein expressions(P<0.05).ASR-AR medium-dosage group was more obvious(P<0.05).Conclusion ASR-AR can inhibit pyroptosis of HUVEC induced by AngⅡ,attenuate endothelial cell dysfunction,thus treating coronary microvascular disease,and its mechanism may be related to the inhibition of the assembly of NLRP3 inflammasome.

Objective:To analyze the prognostic outcomes of 1 147 patients who underwent liver transplantation at Qingdao University Affiliated Hospital and to summarize measures to enhance the efficacy of liver transplantation.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 1 147 liver transplant patients at Qingdao University Affiliated Hospital.Results:The overall postoperative 1-, 3-, and 5-year survival rates for the 1 147 liver transplant patients were 87.20%, 73.40%, and 65.60%, respectively. The survival rates for benign disease liver transplant recipients were 88.01%, 84.98%, and 81.39% at 1, 3, and 5 years post-transplant, respectively, compared to recipients transplanted for malignancies of 78.11%, 64.41%, and 60.06% (all P<0.001). Among the mid vs more recent period, patients' 1-year and 3-year postoperative survival rates were 84.20%, 70.80% vs 90.50%, 71.70%, respectively,significantly in favor of recently enrolled patients ( P=0.022). In the complex surgery group, patients' 1-, 3-, and 5-year survival rates were 82.70%, 65.50%, 56.70%, while in less complicated group, it was 89.00%, 76.50%, 69.20% ( P<0.001). The primary causes of death for benign disease recipients were multi-organ failure (4.1%), while in recipients with malignant disease primary cause of death was tumor recurrence (23.7%). Postoperative complications included primary graft dysfunction, delayed graft function recovery, portal vein thrombosis, hepatic artery thrombosis, biliary stricture, post-transplant lymphoproliferative disorder, and graft-versus-host disease, with occurrence rates of 1.05%, 6.89%, 1.92%, 0.44%, 2.00%, 0.61%, and 0.44%, respectively. Conclusions:With the continuous improvement in surgical techniques and perioperative care levels, the 3-year survival rate of recipients at our center has increased. Malignant diseases and complex liver transplantation remain crucial factors affecting recipient prognosis, highlighting the need to further enhance comprehensive treatment capabilities for patients with malignant diseases and complex surgeries.

Objective To compare the clinical efficacy of cold snare endoscopic mucosal resection(CS-EMR)with conventional endoscopic mucosal resection(EMR)in the treatment of＜20 mm colorectal laterally spreading tumor(CLST).Methods A total of 248 CLST patients undergoing endoscopic resection treated in the First People's Hospital of Huzhou from January 2020 to June 2022 were selected and divided into EMR group and CS-EMR group according to random number table method,with 124 cases in each group.The general data,focal features,surgical indicators and complication rate of two groups were statistically compared.Results There were no significant differences in en bloc resection rate,complete resection rate and postoperative recurrence rate between two groups(P＞0.05).The operation time and hospital stay in CS-EMR group were significantly shorter than those in EMR group,the number of titanium clips and hospitalization costs were significantly lower than those in EMR group,and the incidence of intraoperative bleeding,delayed bleeding and delayed perforation were significantly lower than those in EMR group(P＜0.05).Conclusion In treatment of CLST with a maximum diameter of＜20mm,CS-EMR not only retains the advantages of fewer surgery-related complications,but also has similar therapeutic effect as EMR,and reduces the cost burden of patients,which is worthy of clinical reference and promotion.

AIM:To explore the potential targets and mechanisms of Angelica sinensis and Astraga-lus membranaceus ultrafiltration(RAS-AM)in the treatment of radiation induced myocardial fibrosis(RIMF)through network pharmacology combined experimental validation.METHODS:Using the TC-MSP database TCM@TAIWAN The Taiwan Tradition-al Chinese Medicine Database and TCMID Tradition-al Chinese Medicine Database screen the compo-nents and targets of RAS-AM,and use the Swiss Target Prediction database for target prediction.Obtain RIMF disease targets from Gene Cards and OMIM databases,obtain intersection targets of dis-eases and drugs through Wayne's online tool,ob-tain protein interaction relationships(PPIs)through STRING database,and use Cytoscape 3.9.1 soft-ware to construct a visualized network topology di-agram of"drug component target disease".Con-duct GO and KEGG enrichment analysis on core tar-gets through the David database,and use the mi-crobiome platform for mapping.Experimental veri-fication:Sixty Wistar rats were randomly divided in-to a blank group,a model group,a positive drug group,a RAS-AM low-dose group,a RAS-AM medi-um dose group,and a RAS-AM high-dose group.A RIMF model was established using a 38Gy dose of radiation induction,and was administered orally for 4 weeks.The general condition of the rats was also observed.After blood and heart collection in rats,HE staining was used to observe the morpho-logical changes of myocardial tissue,and ELISA and Western blot methods were used to detect key tar-gets for network pharmacology prediction.RE-SULTS:Network pharmacology analysis revealed 34 active components and 705 targets of Angelica si-nensis and Astragalus membranaceus ultrafiltra-tion,with a total of 154 targets,with IL-6,VEGFA,MMP2,MMP9,and ACE as the top five core tar-gets;GO enrichment analysis screened a total of 153 entries,and KEGG enrichment had 25 path-ways.Experimental part:HE staining results showed that the degeneration and necrosis of myo-cardial cells improved in each medication group,the infiltration of inflammatory cells in the myocar-dial interstitium decreased,and the proliferation of fibrous connective tissue in the myocardial intersti-tium decreased.ELISA and Western blot results showed that compared with the normal group,the expression of IL-6,VEGFA,and MMP-9 in the mod-el group increased.Compared with the model groupthe expression of IL-6,VEGFA,and MMP-9 in each medication group decreased to varying de-grees,in a dose-dependent manner.CONCLUSION:RAS-AM may inhibit RIMF by downregulating core targets such as IL-6,VEGFA protein,MMP-9 pro-tein,and regulating inflammatory pathways,colla-gen degradation,and other processes.

Objective:To explore the impact of donor cold ischemia time(CIT)on early recovery after liver transplantation(LT).Methods:From January 2016 to December 2020, the relevant clinical data were retrospectively reviewed for 456 LT recipients.According to the value of CIT of donor liver, they were assigned into two groups of CIT >5 h and CIT≤5 h. T, Mann-Whitney U or Chi square test was employed for statistical processing.Intraoperative findings and liver function(LF)parameters of two groups were compared, including operative duration, intraoperative volume of hemorrhage, erythrocyte transfusion and anhepatic phase.LF parameters included alanine aminotransferase(ALT), aspartate aminotransferase(AST)and total bilirubin(TB)within Day 1-7 post-LT.Postoperative recovery was evaluated by postoperative stay of intensive care unit(ICU), normalization time of liver function recovery, length of postoperative hospitalization and incidence of postoperative complications.Results:Among them, 407(89.3%)patients underwent classic orthotopic LT.Median CIT of donor liver was 309 min.In CIT≤5 h and CIT >5 h groups, operative duration was[(446.3+ 76.8)vs.(526.0+ 98.1)min], anhepatic phase time[(51.9+ 13.3)vs.(62.6+ 18.9)min]and intraoperative volume of erythrocyte transfusion[(7.3+ 5.8)vs.(10.0+ 6.87)U]. And the differences were statistically significant( P<0.001, 0.001 & 0.001). Postoperative hospitalization stay was longer[(29.1±15.9)vs.(27.1±13.0)]day.And the incidence of postoperative complications was higher in CIT >5 h group[22.7%(54/238)vs.12.4%(27/218)]. And the difference was statistically significant( P=0.045 & 0.004). As compared with CIT≤5 h group, ALT, AST & TB spiked in CIT >5 h group at Day 1 post-operation and the differences were statistically significant( P=0.002, P<0.001, P=0.001). In CIT >5 h group, ALT rose at Day 2/5/6/7 post-LT( P=0.026, 0.026, 0.015 & 0.011), AST jumped from Days 2-6( P=0.002, 0.004, 0.035, 0.029 and 0.019)and TB increased from Days 2-7 post-LT and the differences were statistically significant( P=0.003, 0.014, 0.030, 0.039, 0.027 & 0.009). LF recovered at CIT≤5 h and CIT>5 h group[(10.0±3.2)vs.(10.7±3.3)day]. There were significantly statistical differences( P=0.044). Conclusions:Non-conducive to patient recovery, prolonged cold ischemic time aggravates early LF injury post-LT.

Myocardial infarction （MI） is a common cardiovascular disease in clinical practice and one of the main causes of cardiovascular mortality. Its pathogenesis is complex and associated with oxidative stress reactions. Nuclear factor E₂-related factor 2 （Nrf2） is a key factor in regulating oxidative stress reactions. It can regulate the expression of heme oxygenase-1 （HO-1）， playing a role in maintaining the oxidative-reductive homeostasis in the body. During the course of MI， the biological activity and levels of Nrf2 and HO-1 decrease， leading to weakened tissue antioxidant and anti-inflammatory capabilities， endothelial damage in myocardial blood vessels， release of vascular cell adhesion factors， and impaired endothelial function. In recent years， many basic research studies have explored the role and mechanisms of traditional Chinese medicine （TCM） in treating MI by modulating the Nrf2/HO-1 signaling pathway. The results have indicated that the Nrf2/HO-1 signaling pathway is an important potential target for TCM in the treatment of MI. This article reviewed the mechanism of the Nrf2/HO-1 signaling pathway in MI and the research progress of TCM in targeting and regulating this pathway， aiming to provide a theoretical basis for the prevention and treatment of MI and further drug development.

OBJECTIVE: To explore the clinical features and genetic basis for a child with early-onset Isolated sulfite oxidase deficiency (ISOD). METHODS: A child with ISOD who was admitted to Weihai Hospital Affiliated to Qingdao University on May 10, 2020 was selected as the study subject. Clinical data of the child was analyzed. The child and her parents were subjected to trio-whole exome sequencing, and candidate variants were verified by Sanger sequencing. RESULTS: The female neonate was transferred to the intensive care unit due to "secondary pollution of amniotic fluid and laborious breathing for 11 minutes", and had developed frequent convulsions. Genetic testing revealed that she has harbored c.1200C>G and c.188G>A compound heterozygous variants of the SUOX gene, which were inherited from her mother and father, respectively. The c.1200C>G has been described previously and was rated as pathogenic based on guidelines from the American College of Medical Genetics and Genomics, whilst the c.188G>A variant was unreported previously and rated as variant of unknown significance. CONCLUSION The compound heterozygous variants of the SUOX gene probably underlay the ISOD in this child. Above finding has enriched the spectrum of SUOX gene variants and provided a basis for the clinical diagnosis and genetic counseling.
