ObjectiveThis paper aims to investigate the potential molecular biological mechanism of Buyang Huanwu Tongfeng decoction in treating hyperuricemia and gouty arthritis by network pharmacology and molecular docking technology and preliminarily verify the mechanism through animal experiments. MethodsThe active ingredients and targets in the Buyang Huanwu Tongfeng decoction were obtained by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and ETCM databases. The DisGeNET and GeneCards databases were utilized to acquire disease targets associated with hyperuricemia and gouty arthritis. These disease targets were then intersected with drug targets to identify key targets. The R language ClusterProfiler package and Python were employed for conducting gene ontology（GO） enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） enrichment analysis. The regulatory network diagram of the drug-key target-function-pathway was visualized using Cytoscape 3.9.1 software， and the protein-protein interaction （PPI） network for key targets was depicted. Finally， the hub gene was determined through topological analysis. Auto Dock， PyMOL， and other software were used for molecular docking to explore the possible therapeutic mechanism of Buyang Huanwu Tongfeng decoction for hyperuricemia and gouty arthritis. In animal experiments， a composite rat model of hyperuricemia induced by intraperitoneal injection of oteracil potassium combined with gouty arthritis induced by the modified Coderre method was established. Through hematoxylin-eosin（HE） staining， uric acid test， enzyme linked immunosorbent assay（ELISA）， Western blot， and real-time polymerase chain reaction（Real-time PCR）， the molecular mechanism and key targets of Buyang Huanwu Tongfeng decoction for treating hyperuricemia and gouty arthritis were observed. ResultsAfter screening and removing duplicate values， 76 active ingredients and 15 key targets were finally obtained. GO enrichment analysis yielded that the treatment of hyperuricemia and gouty arthritis with Buyang Huanwu Tongfeng decoction was significantly associated with acute inflammatory response， astrocyte activation， regulation of interleukin （IL）-8 production， nuclear receptor activity， and binding of growth factor receptor. KEGG pathway enrichment analysis obtained that the key target genes were significantly associated with the IL-17 signaling pathway， advanced glycosylation end/receptor of advanced glycation endproducts（AGE/RAGE） signaling pathway， anti-inflammatory， and other pathways. PPI network indicated that albumin（ALB）， peroxisome proliferator-activated receptor-γ （PPAR-γ）， IL-6， IL-1β， and C-reactive protein（CRP） were the key protein targets. The molecular docking results showed that ALB had the strongest binding force with beta-carotene （β-carotene）. Biochemical results showed that blood uric acid decreased in the Buyang Huanwu Tongfeng decoction groups. HE staining results showed that the low-dose （7.76 g·kg^-1·d^-1）， medium-dose （15.53 g·kg^-1·d^-1）， and high-dose （31.05 g·kg^-1·d^-1） groups of Buyang Huanwu Tongfeng decoction had different degrees of remission， and the remission of the high-dose group was the most obvious. Fibroblastic tissue hyperplasia in synovial joints accompanied with inflammatory cell infiltration， as well as inflammatory cell infiltration in renal tissue of the high-dose group was significantly reduced， followed by the medium-dose and low-dose groups， and the expression of ALB， PPAR-γ， IL-6， IL-1β， and CRP was down-regulated to different degrees. ConclusionBy regulating the targets such as ALB， PPAR-γ， IL-6， IL-1β， and CRP， inhibiting the PPAR-γ/nuclear transcription factor （NF）-κB pathway， and reducing AGEs/RAGE-mediated inflammation， Buyang Huanwu Tongfeng decoction exerts anti-inflammatory and analgesic effects and activates blood circulation and diuresis in the treatment of hyperuricemia and gouty arthritis.

This article reports a diagnostically and therapeutically challenging case of small intestinal marginal zone lymphoma. The patient presented with recurrent abdominal pain as the chief complaint, and imaging revealed multifocal small bowel wall thickening with high uptake, multisegmental luminal stenosis, and proximal dilation. Initial diagnostic workup, including gastroscopy, colonoscopy, and enteroscopy with biopsy, failed to establish a definitive diagnosis. Empirical anti-tuberculosis therapy was ineffective. A repeat enteroscopic biopsy performed over eight months after symptom onset eventually confirmed the diagnosis of mucosa-associated lymphoid tissue (MALT) extranodal marginal zone lymphoma. Despite three different chemotherapy regimens, the patient's intestinal obstruction symptoms persisted, with imaging still showing multifocal bowel wall thickening and hypermetabolic activity. A critical diagnostic dilemma arose regarding whether the PET/CT-positive lesions represented residual lymphoma or fibrotic scarring, whether further chemotherapy adjustments were warranted, and whether surgical resection was necessary. Multidisciplinary discussion concluded that imaging had limited discriminatory value in this scenario and that surgical intervention should be pursued if feasible. The patient successfully underwent partial small bowel resection, with postoperative pathology confirming no residual lymphoma but significant fibrotic changes. The patient has since resumed a normal diet, with body weight nearly restored to pre-illness levels. This case highlights that fibrotic transformation is a common sequela of treated marginal zone lymphoma and that PET/CT may misleadingly suggest residual disease, potentially leading to unnecessary chemotherapy. Timely surgical intervention is crucial in such scenarios.

AIM:To study the mechanism of Sihei-fang(SHF)in improving pigment deficiency disease(PD)by combining network pharmacology and me-tabolomics.METHODS:Using zebrafish embryos with pigment deficiency disease induced by 1-phe-nyl-2-thiourea(PTU)as an animal model,the ef-fects of SHF extract(0.01,0.02,0.04 mg/mL)on the morphology,melanin area,tyrosinase activity,and melanin content of zebrafish embryos were an-alyzed.Ultra high performance liquid chromatogra-phy-mass spectrometry(UHPLC-MS)was used to screen differential metabolites and obtain relevant metabolic pathways in the SHF treatment of mela-nin deficient zebrafish embryos model.Network pharmacology was used to obtain key targets for SHF treatment of PD and conduct KEGG pathway enrichment analysis.Import The identified differen-tial metabolites and SHF PD intersection targets were imported into the Metscape plugin,to estab-lish a"metabolite reaction enzyme gene"network,and search for key metabolites,targets,and meta-bolic pathways.RESULTS:SHF treatment could in-crease the formation of zebrafish melanin,activate tyrosinase activity,and increase melanin content.Metabolomics analysis obtained 54 differential me-tabolites,and metabolic pathway analysis was con-ducted on these metabolites,involving the biosyn-thesis of phenylalanine,tyrosine,and tryptophan,glycerol phospholipid metabolism,tyrosine metab-olism,linoleic acid metabolism,and aminoacyl tRNA biosynthesis pathways.Network pharmacolo-gy had obtained 55 cross targets of components and diseases.KEGG involved pancreatic cancer,TNF,cancer and other signal pathways.The joint analysis of metabolomics and network pharmacolo-gy identified four key targets:COMT,CYP1B1,TYR,and ALDH2;three key metabolites:L-tyrosine,ho-movanllate,L-lysine;three important metabolic pathways:tyrosine metabolism,valine/leucine/iso-leucine degradation,and lysine metabolism.CON-CLUSION:SHF has a good improvement effect on PD,and combined with metabolomics and network pharmacology,SHF may enhance its influence on the tyrosine metabolism pathway by regulating the metabolite L-tyrosine,thereby promoting the for-mation of melanin.

Objective: : Kinesin family member C1 (KIFC1), a non-essential kinesin-like motor protein, has been found to serve a crucial role in supernumerary centrosome clustering and the progression of several human cancer types. However, the role of KIFC1 in glioma has been rarely reported. Thus, the present study aimed to investigate the role of KIFC1 in glioma progression. Methods: : Online bioinformatics analysis was performed to determine the association between KIFC1 expression and clinical outcomes in glioma. Immunohistochemical staining was conducted to analyze the expression levels of KIFC1 in glioma and normal brain tissues. Furthermore, KIFC1 expression was knocked in the glioma cell lines, U251 and U87MG, and the functional roles of KIFC1 in cell proliferation, invasion and migration were analyzed using cell multiplication, wound healing and Transwell invasion assays, respectively. The autophagic flux and expression levels matrix metalloproteinase-2 (MMP2) were also determined using imaging flow cytometry, western blotting and a gelation zymography assay. Results: : The results revealed that KIFC1 expression levels were significantly upregulated in glioma tissues compared with normal brain tissues, and the expression levels were positively associated with tumor grade. Patients with glioma with low KIFC1 expression levels had a more favorable prognosis compared with patients with high KIFC1 expression levels. In vitro, KIFC1 knockdown not only inhibited the proliferation, migration and invasion of glioma cells, but also increased the autophagic flux and downregulated the expression levels of MMP2. Conclusion : Upregulation of KIFC1 expression may promote glioma progression and KIFC1 may serve as a potential prognostic biomarker and possible therapeutic target for glioma.

Objective:To analyze the clinical characteristics of pneumatosis cystoides intestinalis in the Tibet Plateau, and to explore the diagnosis and treatment method of this disease.Methods:The medical records of 60 patients with confirmed pneumatosis cystoides intestinalis who were admitted to Tibet Autonomous Region People's Hospital from January 2014 to July 2021 were retrospectively analyzed. A descriptive statistical analysis was made.Results:The male-to-female ratio of 60 patients with pneumatosis cystoides intestinalis was 2.2: 1. The average age of onset was (48.6 ± 14.5) years. The average living altitude was (3 832.3 ± 399.8) meters. All patients were admitted mainly because of gastrointestinal symptoms. Twenty patients had hemorrhoids, chronic hepatitis, and gallstones. Pneumatosis cystoides intestinalis was confirmed by endoscopic examination in 59 patients and by surgery in 1 patient. Among the patients, 43 patients had lesions involving the colon, 2 patients had lesions involving the small intestine, and 1 patient had lesions involving the duodenum. The specific lesion sites were not determined in the remaining 14 patients because of unclear descriptions of the examination results. Two patients were positive for fecal occult blood tests, with a median hemoglobin value of 156.0 g/L. Forty-nine patients were given hyperbaric oxygen therapy, medication, and diet adjustment. Eleven patients were treated surgically. Clinical symptoms were relieved in 43 patients, and 17 patients were lost to follow-up.Conclusion:Pneumatosis cystoides intestinalis is relatively common in Tibet Plateau, and more common in men than in women. It occurs at any age. Clinical manifestations are not specific. The lesions most often involve the colon. The disease is mainly diagnosed by endoscopy. Individualized treatment based on different causes can help improve the prognosis of pneumatosis cystoides intestinalis.

Objectives:To investigate the relationship between visceral adipose index and glomerular filtration rate in patients with type 2 diabetes mellitus.Methods:A total of 1 036 patients with type 2 diabetes mellitus who received treatment in The Second Affiliated Hospital of Xi'an Jiaotong University from May 2017 to May 2018 were included in this study. The visceral adipose index was detected using a bioresistance assay. These patients were divided into four groups using the quartile method: Visceral adipose index < 8.10 (q1 group, n = 246), 9.60 > visceral adipose index ≥ 8.10 (q2 group, n = 64), 11.10 > visceral adipose index ≥ 9.60 (q3 group, n = 423), visceral adipose index ≥ 11.10 (q4 group, n = 233). One-way analysis of variance was performed to compare the differences among groups. Partial correlation and multiple regression were used to analyze the correlation between body mass index, waist circumference, waist-to-height ratio, waist-to-hip ratio, body fat content, visceral adipose index, and urinary microalbumin and glomerular filtration rate. Results:With the increase in the visceral adipose index, the glomerular filtration rate gradually decreased. The glomerular filtration rate in the q1, q2, q3, q4 groups was (112.19 ± 31.74) mL·min -1·1.73 m -2, (106.14 ± 28.26) mL·min -1·1.73 m -2, (104.73 ± 23.63) mL·min -1·1.73 m -2, (103.40 ± 27.51) mL·min -1·1.73 m -2, respectively. In the female group, with the increase in visceral adipose index, the glomerular filtration rate decreased gradually. After controlling for age, sex, diabetes, and hypertension, the visceral adipose index was significantly correlated with the glomerular filtration rate ( r = -0.10, P < 0.001). Multiple regression analysis showed that visceral adipose index and waist-to-height ratio were closely related to glomerular filtration rate ( F = 6.00, P < 0.001). Conclusion:With the increase of visceral adipose index, body mass index, waist circumference, waist-to-height ratio, waist-to-hip ratio, body fat content, and urinary microalbumin increased gradually. When the visceral adipose index is greater than 9.60, the glomerular filtration rate is significantly decreased. Therefore, it is suggested to adopt various methods to evaluate obesity in clinical work, and visceral fat index should be paid more attention, especially when the visceral fat index is greater than 9.60.

Objective:To investigate the risk factors for intraoperative hemorrhage during endoscopic submucosal dissection (ESD) for colorectal lesions.Methods:Data of 386 patients with colorectal lesions, who underwent ESD at The Third People's Hospital of Datong and its cooperative hospital, Nanjing Drum Tower Hospital, from December 2019 to August 2021 were retrospectively analyzed. The patients were divided into the hemorrhage group ( n=85) and the non-hemorrhage group ( n=301) according to intraoperative hemorrhage. The correlationship of patients'basic information, lesion-related factors and hemorrhage during colorectal ESD was analyzed. Univariate and multivariate logistic regression were used to identify the risk factors for intraoperative hemorrhage during ESD. The risk predictive model of intraoperative hemorrhage during ESD was established according to the screened risk factors, and receiver operator characteristic (ROC) curve was used to evaluate the predictive model. Results:Univariate logistic regression showed that a history of diabetes ( OR=2.340, P<0.05), a history of coronary atherosclerotic heart diseases ( OR=3.100, P<0.05), the lesion located in the rectum ( OR=3.272, P<0.05), longer lesion ( OR=1.093, P<0.05), wider lesion ( OR=1.057, P<0.05), larger lesion ( OR=1.126, P<0.05), depressed lesion ( OR=6.128, P<0.05), the laterally spreading lesion ( OR=2.651, P<0.05), the lesion infiltrated into the SM-S layer ( OR=0.088, P<0.05), the lesion infiltrated into the SM-D layer ( OR=0.174, P<0.05), the diameter of hemorrhage vessels 0.5~<1.0 times of the diameter of incision knife ( OR=246.854, P<0.05), the postoperative pathology as early cancer ( OR=7.000, P<0.05) were risk factors for intraoperative hemorrhage during ESD. Considering the quantitative relationship between the length, the width and the area of lesions, multi-factor models were constructed using the length and area of lesions respectively. Forward stepwise regression was used to screen variables and determine the final model, and the results showed that a history of coronary atherosclerotic heart diseases, the depressed lesion, the longer lesion, the larger lesion, the diameter of hemorrhage vessels 0.5~<1.0 times of the diameter of the incision knife were independent risk factors for intraoperative hemorrhage during ESD. The two modeling results of the lesion length and the lesion area were very similar. Therefore, lesion length was recommended to describe lesions in clinical practice. Conclusion:A history of coronary atherosclerotic heart disease, the depressed lesion, the longer lesion, the larger lesion, the diameter of vessels 0.5~<1.0 times of that of the incision knife are independent risk factors for intraoperative hemorrhage during ESD.
