“Inflammation-cancer” transformation of chronic atrophic gastritis （CAG） refers to the process in which the gastric mucosa， in the context of CAG， progresses through stages of precancerous lesions of gastric cancer （PLGC）， such as intestinal metaplasia and dysplasia， and eventually develops into gastric cancer （GC）. In China， the incidence and mortality rates of GC rank among the highest in the world， and the proportion of GC cases caused by gastric mucosal infection and inflammation has been increasing. Modern medical treatments for CAG and PLGC mainly rely on drug therapy， endoscopic resection， and regular surveillance. Although these disease management strategies are relatively mature， they present limitations in early lesion prevention and recurrence risk control. Therefore， it is imperative to identify therapeutic approaches for CAG and PLGC that offer preventive， reversible， and recurrence-reducing benefits. With advances in research on the mechanisms underlying inflammation-cancer transformation and the integration of traditional Chinese and Western medicine， the advantages of TCM in preventing and even reversing early-stage CAG and PLGC have gradually become apparent. This review explored the mechanisms of inflammation-cancer transformation in CAG from five aspects： inflammatory microenvironment， autophagy， glycolysis， bile acids， and ferroptosis. In conjunction with TCM theory and a deeper understanding of the distinct mechanisms involved in the inflammation-cancer transformation of CAG， this review further discussed the specific mechanisms through which TCM intervened in treating CAG and PLGC， with the aim of providing theoretical support and therapeutic insights for future clinical applications.

Objective:To extract the early result of postoperative echocardiographic evaluation in patients underwent left ventricular assist device (LVAD) implantation, and to assess the efficacy of surgical treatment for end-staged heart failure.Methods:Between June 2019 and May 2023, the patients underwent left ventricular assist device implantation were enrolled in this study. Demographic baseline characteristics and perioperative echocardiographic parameters were collected and analyzed.Results:A total of 28 patients were included in the study. After LVAD implantation, the heart sizes of the patients obviously reduced and the left heart contractibility function improved. The right ventricular contractibility remained stable. The proportion of the patients with moderate to severe mitral regurgitation was significantly reduced, but patients with mild to moderate aortic insufficiency increased. No serious complications such as death, pericardial tamponade and thrombosis events were observed during the follow-up period.Conclusion:LVAD implantation improved the left cardiac function, while the right cardiac function remained stable. However, it should be paid attention that the aortic valve function was impaired after the surgery. Generally, the early results of LVAD implantation for the treatment of end-stage heart failure were satisfactory.

Objective To study the effect and mechanism of Anchusa italica Retz on cerebral ischemia-reperfusion inju-ry in rats based on the target network of active compounds in Anchusa italica Retz.Methods The rat model of cerebral ische-mia-reperfusion injury was established by the thread occlusion method.After performing ischemia for 1.5 h and then reperfusion for 24 h,the neurological function of rats was scored and the volume of cerebral infarction was measured by the 2,3,5-triphenyltet-razolium chloride staining method.The molecular network analysis technique of network pharmacology,protein-protein interaction network,gene ontology(GO)enrichment analysis,KEGG signal pathway analysis,and molecular docking was used to study the mechanism of Anchusa italica Retz in the treatment of cerebral ischemia-reperfusion injury.Results The administration of An-chusa italica Retz could significantly improve the neurobehavioral dysfunction caused by cerebral ischemia-reperfusion injury and reduce the pathological injury of brain tissue.Anchusa italica Retz could regulate inflammation,apoptosis,protein phosphorylation,and other biological processes through 143 ischemic stroke-related targets,and interfere with the TNF signal pathway,VEGF signal pathway,HIF-1 signal pathway,and other pathways.Conclusion Network pharmacology and experimental verification had shown that Anchusa italica Retz could effectively reduce brain injury and protect neurological function through multi-target,multi-mechanism,and holistic treatment of cerebral ischemia-reperfusion injury.

Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disorders (PTLD) are one of the most severe complications after hematopoietic stem cell transplantation (HSCT). This study includes 31 cases of aplastic anemia (AA) patients who developed PTLD after haploidentical transplantation, summarizing their clinical characteristics and categorizing them into either rituximab monotherapy group or combination therapy group based on whether their condition improved by 1 log after a single dose of rituximab. The incidence of PTLD after HSCT in children with AA was 10.16%, and the incidence of PTLD in patients with age >10 years was significantly increased ( χ2=11.336, P=0.010). Of the 31 patients, 27 were clinically diagnosed and 4 were pathologically confirmed. Finally, 15 patients were classified into the rituximab treatment group and 15 patients into the combination treatment groups. Finally three patients died, and the 2-year overall survival rate was (89.7±5.6) %. Standard pre-treatment protocols and EBV reactivation are risk factors affecting the prognosis of PTLD. There was no statistically significant difference in the impact of the two treatment schemes on prognosis.

Objective:To investigate the efficacy and safety of venetoclax combined with the decitabine, cytarabine, and homoharringtonine (HHT) regimen and donor lymphocyte infusion (DLI) for the preventive and salvage therapy of pediatric acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) after allogeneic hematopoietic stem cell transplantation (HSCT) .Methods:A total of 29 relapsed pediatric/minimal residual disease-positive AML after HSCT were recruited at the Peking University Institute of Hematology from January 1, 2021, to June 1, 2023. They were treated with the above combination regimen and administered with DLI after 24-48 hours at the end of chemotherapy, and the treatment response and adverse reactions were regularly assessed.Results:The overall response rate (ORR) was 75.8%, CR rate was 88.9% (8/9) in the hematologic relapse group, and MRD negativity rate was 61.1% (11/18) in the MRD-positive group. The incidence of agranulocytosis, anemia, and thrombocytopenia with a classification above grade 3 were 100%, 82.7%, and 100%, respectively. The median time of the granulocyte deficiency period was 15 days. Acute graft-versus-host diseases (aGVHD) with a classification of grades Ⅲ-Ⅳ occurred in 11.1% of the patients after DLI, while moderate or severe cGVHD occurred in 7.4% of the patients. The single risk factor for ORR was MNC counts of less than 10×10 8/kg, and the relapse occurred within 100 days. At a median follow-up of 406 days, the 1-year OS was 65%, and the 1-year OS was 57% in the group with no reaction ( P=0.164) compared with 71% in the group who had an overall reaction. Conclusion:The combined regimen based on the DAC, VEN, and modified HA regimen showed a high response rate in the salvage therapy for pediatric AML after the relapse of HSCT. However, bridging to transplantation should be performed immediately after remission to result in a long survival rate.

Objective:To develop the Clinical Nurse Extra Task Load Scale and test its reliability and validity.Methods:Based on the job demand-control model, a primary scale was formed through literature search and qualitative interviews, as well as Delphi consultation and pre-survey. In September 2023, 813 clinical nurses from First Affiliated Hospital of Xinxiang Medical University and Xinxiang Central Hospital were selected for reliability and validity testing. In October 2023, 1 050 clinical nurses from First Affiliated Hospital of Xinxiang Medical University and Xinxiang Central Hospital were selected for investigation, and the reliability and validity of the scale were tested.Results:The final Clinical Nurse Extra Task Load Scale included two dimensions and a total of 12 items. The item-level content validity index was 0.86 to 1.00, and the scale-level content validity index was 0.84. Exploratory factor analysis extracted two common factors, with a cumulative variance contribution rate of 74.55%. Confirmatory factor analysis showed that χ 2/ df was 1.613, GFI was 0.928, CFI was 0.971, NFI was 0.928, IFI was 0.971, and RMSEA was 0.024. Cronbach's α coefficient of the work environment demand dimension was 0.897, Cronbach's α coefficient of individual behavior restriction was 0.955, Cronbach's α coefficient of the total scale was 0.950, and the split-half reliability was 0.850. Conclusions:The Clinical Nurse Extra Task Load Scale developed has a good reliability and validity, and can be used to evaluate and quantify the extra task load for clinical nurses.

Huntington's disease(HD)is an autosomal dominant neurodegenerative disease,with the main symptoms including chorea-like involuntary movements,psychiatric behavioral abnormalities,and cognitive impairment,which severely affect the lives of patients and consume extensive social and medical resources.Various experimental animal models of HD have been successfully established,to further our understanding of the pathological mechanisms and to explore treatment method of HD.This review outlines the establishment and application of various animal models,ranging from Caenorhabditis elegans,Drosophila melanogaster and zebrafish to mice,rats and miniature pigs,and analyzes the characteristics and advantages of the different models.By reviewing the different animal models and their relevant evaluation indicators,this article emphasizes the importance of utilizing a combination of multiple animal models to promote a deeper understanding of the disease mechanisms and develop effective treatment strategies.

Objective:To evaluate the role of lactate-induced mitochondrial division of spinal cord neurons in diabetic neuropathic pain (DNP) in mice.Methods:Thirty-six SPF-grade healthy adult male C57BL/6 mice, aged 2 months, weighing 20-25 g, were divided into 3 groups ( n=12 each) using a random number table method: control group (CON group), DNP group, and DNP+ sodium oxalate group (OXA group). The diabetic model was established by intraperitoneal injection of streptozotocin 130 mg/kg. After the diabetic model was successfully established, sodium oxalate 750 mg/kg was intraperitoneally injected once a day for 4 consecutive weeks to inhibit lactate production in OXA group, while the equal volume of normal saline was given instead at the same time in C group and DNP group. The mechanical paw withdrawal threshold (MWT) of the left hindpaw was measured before developing the model and at 1, 2, 3 and 4 weeks after developing the model. After completing the last behavioral testing, the spinal cord tissue of the lumbar segment (L 4-6) was taken for determination of the levels of lactate in serum and spinal cord tissues (by the colorimetric method), expression of the mitochondrial membrane potential, reactive oxygen species (ROS) content (using JC-1 or DHE probes), expression of mitochondrial dynamin-related protein 1 (Drp1) and mitochondrial protein mitofusin 2 (Mfn2) (by Western blot), and co-expression of Drp1 and neuronal neuronal marker neuronal nuclear protein (NeuN) (by immunofluorescence double labeling) and for examination of the structure and the number of mitochondria (with a transmission electron microscope). Results:Compared with C group, the MWT was significantly decreased after developing the model, the levels of lactate in serum and spinal cord tissues and ROS content in the spinal cord were increased, the mitochondrial membrane potential was decreased, the Drp1 expression was up-regulated, the Mfn2 expression was down-regulated, the number of mitochondria was increased, the area was reduced ( P<0.05), and the co-expression of Drp 1 and NeuN was increased in DNP group and OXA group. Compared with DNP group, the MWT was significantly increased after developing the model, the levels of lactate in serum and spinal cord tissues and ROS content in the spinal cord were decreased, the mitochondrial membrane potential was increased, the Drp1 expression was down-regulated, the Mfn2 expression was up-regulated, the number of mitochondria was decreased, the area was increased ( P<0.05), and the co-expression of Drp 1 and NeuN was decreased in OXA group. Conclusions:Lactate-induced excessive mitochondrial division of spinal cord neurons can lead to mitochondrial dysfunction, which may be involved in the maintenance mechanism of DNP in mice.
