ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy, Jilin People’s Hospital, from May 2022 to June 2024, and related data were collected, including the success rate of surgery, the technical success rate of gallbladder polyp removal, the superselective method of cystic duct, the time of operation, the time of gallbladder polyp removal, and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%, and of all eight patients, three patients used guide wire to enter the gallbladder under direct view, while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes, and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2 — 8 mm, and pathological examination showed inflammatory polyps in three patients, adenomatous polyps in one patient, and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2 — 27 months after surgery, and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

ObjectiveTo investigate the intervention effect of Jiedu Tongluo Tiaogan prescription (JTTP) in protecting pancreatic β cells by targeting the bile acid Takeda G protein-coupled receptor 5 (TGR5)/cyclic adenosine monophosphate (cAMP) signaling pathway against NOD-like receptor protein 3 (NLRP3) inflammasome. MethodThirty-two male SPF-grade db/db mice were randomly divided into the model group, low-dose JTTP group (3.6 g·kg-1), high-dose JTTP group (7.2 g·kg-1), and metformin group (0.2 g·kg-1). Eight db/m mice were assigned to the blank control group. The mice were treated with drugs for 8 weeks, and fasting blood glucose (FBG) was measured every 2 weeks. Oral glucose tolerance tests (OGTT) were conducted after the last administration. Enzyme-linked immunosorbent assay (ELISA) was performed to detect fasting insulin (FINS), and the homeostasis model assessment of β-cell function (HOMA-β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1β levels were calculated. Hematoxylin-eosin (HE) staining was used to observe pathological changes in mouse pancreatic tissue. Immunofluorescence was performed to detect insulin expression in mouse pancreatic tissue. Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression of proteins and mRNAs of key targets in the TGR5/cAMP signaling pathway and NLRP3 inflammasome. ResultCompared with blank group, FBG, OGTT, FINS, IL-6, TNF-α and IL-1β in model group were significantly increased (P<0.01). Compared with model group, after 6 weeks of drug treatment, FBG level in JTTP group and metformin group decreased significantly (P<0.01). The results of OGTT experiment showed that compared with model group, the blood glucose levels of mice in each administration group were decreased at all time points (P<0.05, P<0.01), and the levels of FINS, TNF-α and IL-6 in JTTP dose groups and metformin group were significantly decreased. The level of IL-1β in JTTP high-dose group and metformin group was significantly decreased (P<0.01). Pancreatic pathology showed that the islets in the model group were irregular in shape, uneven in distribution, and showed signs of atrophy. The prognosis of JTTP was that the cell count increased and the boundary was clearer. Immunofluorescence results showed that the islet cells in the blank group were arranged in an orderly and full shape with appropriate insulin secretion, while the islet cells in model group were distorted in shape, atrophy in structure and less insulin secretion. The insulin content of mice in JTTP and metformin group was significantly increased. Compared with blank group, mRNA expressions of NLRP3, apoptosis-related spot-like protein (ASC) and Caspase-1 in pancreatic tissues of model group were significantly increased (P<0.01). Compared with model group, JTTP high-dose group and metformin group promoted the up-regulation of TGR5 and cAMP mRNA, and down-regulated the mRNA expressions of NLRP3, ASC and Caspase-1 (P<0.05, P<0.01). Compared with blank group, the expression of TGR5 protein in model group was significantly decreased (P<0.01). Compared with model group, TGR5 protein in JTTP high-dose group and metformin group was significantly increased (P<0.01).

Objective:To investigate the genomic profiles and immune microenvironment of olfactory neuroblastoma (ONB).Methods:Nineteen ONB cases diagnosed in the Beijing Tongren Hospital from May 2018 to October 2022 were divided into low-grade and high-grade groups according to the Hyams grading system, including 7 low-grade and 12 high-grade ONB. Whole exome sequencing and multiplex immunofluorescence analyses were performed on tissue samples of these ONB.Results:A total of 929 nonsynonymous alterations were identified in 18 of the 19 ONB (18/19) cases. The most commonly altered cancer-related genes were CTNNB1 (3/19) and ZNRF3 (3/19). The most mutated oncogenic pathways were the WNT and RAS pathways. The median tumor mutation burden (TMB) was 0.45/Mb, ranging from 0 to 3.25. The median tumor neoantigen load (TNB) was 9.39 neoantigens/Mb, ranging from 0 to 38.30. The median allelic mutation tumor heterogeneity (MATH) score was 16.95, ranging from 3.05 to 117.47. Only one of the 19 cases expressed PD-L1 (composite positive score, CPS>1) in the tumor cells. The median percentage of CD8 + tumor-infiltrating lymphocyte (TIL) in the tumor region was 1.08%. No significant differences were observed between the low-and high-grade groups for mutant genes, mutant pathways, TMB, TNB, MATH, PD-L1 expression levels, or CD8 + TILs percentage( P>0.05). However, the low-grade group showed significantly more CD68 + macrophages in both the tumor and total region than the high-grade group. Notably, CD68 +CD163 - macrophages accounted for an average of 80.52% of CD68 + macrophages. Conclusions:CTNNB1 and ZNRF3 are the most commonly altered cancer-related genes. The low expression of PD-L1 and the low percentage of CD8 + TIL indicate that ONB might not be sensitive to immunotherapy. The percentage of M1-type macrophages in low-grade ONB is significantly higher than that in high-grade ONB, suggesting that M1-type macrophages may be involved in the progression of ONB from low-grade to high-grade.

On the basis of the clinical characteristics of atherosclerosis(AS)in traditional Chinese medicine(TCM)and Western medicine,this paper analyzes common animal models of AS.The coincidence of clinical characteristics of the models was scored in the hope of providing new ideas and a reference for those studying AS.This paper reviews the varieties,modeling method,modeling principles,and characteristics of common animal models of AS.Moreover,similarities among common animal models,in terms of their clinical diagnostic criteria and symptom characteristics,were assessed.High-fat feeding type,mechanical injury combined with high-fat feeding type,genetic engineering combined with high-fat feeding type,chemical induction combined with high-fat feeding type,and combined Chinese clinical syndrome and Western disease AS models are widely established.Comparative analysis showed that balloon injury combined with high fat feeding type,ApoE receptor-knockout mouse combined with high-fat diet type,and phlegm and blood stasis type models of disease and symptom combinations showed a comparatively high level of clinical agreement between Chinese and Western medicine.Presently,most animal models of AS have a high degree of relevance to Western medicine,and the evaluation criteria used for the models are predominately from a Western medicine perspective.Models that combine disease and syndrome are lacking,hindering the development of wholism concepts and treatment through the differentiation of syndromes used in TCM.Therefore,establishing an animal model with a high degree of accuracy and coincidence between TCM and Western perspectives that combines the disease and its TCM symptoms is a top priority for studying the prevention and treatment of AS.

Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related mortality.Although surgical resection,liver trans-plantation,and microwave ablation are key curative treatments,complications arise due to the insidious onset and rapid progression of HCC.At the time of diagnosis,microscopic metastasis may already be present in some patients,leading to a significant risk of recurrence,even after radical treatment.In recent years,systemic anti-tumor therapies,including targeted therapies and immune checkpoint inhibitors,have shown significant promise in reducing recurrence rates and prolonging survival.This review aims to integrate recent research findings to provide guidance for adjuvant therapy following radical surgery for HCC.

Regardless of the underlying etiology, renal fibrosis is the final histological outcome of progressive kidney disease. Unilateral ureteral obstruction (UUO) is an ideal and reproducible experimental rodent model of renal fibrosis, which is characterized by tubulointerstitial inflammatory responses, accumulation of extracellular matrix, tubular dilatation and atrophy, and fibrosis. The magnitude of UUO-induced renal fibrosis is experimentally manipulated by the species chosen, animal age, and the severity and duration of the obstruction, while relief of the obstruction allows the animal to recover from fibrosis. The pathogenesis of renal fibrosis is complex and multifactorial and is orchestrated by activation of renin-angiotensin system (RAS), oxidative stress, inflammatory response, transforming growth factor beta 1-Smad pathway, activated myofibroblasts, cell death (apoptosis, autophagy, ferroptosis, and necroptosis), destruction of intracellular organelles, and signaling pathway. The current therapeutic approaches have limited efficacy. Inhibition of RAS and use of antioxidants and antidiabetic drugs, such as inhibitors of sodium-glucose cotransporter 2 and dipeptidyl peptidase-4, have recently gained attention as therapeutic strategies to prevent renal scarring. This literature review highlights the state of the art regarding the molecular mechanisms relevant to the management of renal fibrosis caused by UUO.
