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.

Objective To compare the positioning errors,required planning target volume(PTV)outer expansion boundary and three-dimensional displacement of two different positioning fixation devices CIVCO Uni-frame carbon fiber adjustable angle head frame and domestic integrated board in radiotherapy for the pa-tients with head tumor,and to investigate the application value of CIVCO headrest in the positioning of head tumor radiotherpay.Methods The clinical data of 82 patients with head tumors who underwent radiotherapy in this hospital from January to December 2023 were analyzed retrospectively.The patients were divided into the adjustable angle head frame group and integrated plate group,41 cases in each group.Both groups were fixed with U-shaped thermoplastic head film.Radiotherapy was performed by using ELEKTA infinity linear accelerator.The cone beam computed tomography(CBCT)image guidance was used,combined with bone reg-istration and manual calibration to obtain the patient positioning errors in three directions:X axis,Y axis and Z axis.The positioning error data of each CBCT was recorded;based on the PTV outward expansion boundary formula(2.5∑+0.7σ),the PTV outward expansion boundaries required by the two fixation devices in all di-rections for the treatment of head tumors were calculated;the 3-dimensional spatial displacement was calculat-ed based on the patient's single radiotherapy positioning error.Results The absolute positioning errors in the X,Y,and Z directions of the adjustable angle head frame group were 0.13(0.07,0.22),0.16(0.16,0.27),0.10(0.05,0.18)cm respectively,which in the integrated board group were 0.14(0.07,0.24),0.18(0.08,0.32),0.09(0.04,0.10)cm respectively.The absolute error of the Y direction in the adjustable angle head frame group was smaller than that of the integrated board group(P=0.006),and the difference in the relative error between the two groups was not statistically significant(P＞0.05).According to the PTV expansion formula,the calculated expansion boundaries of the X,Y,and Z directions in the adjustable head frame group were 0.24,0.30,0.22 cm,which in the integrated plate group were 0.21,0.36,0.21 cm,respectively.The three-dimensional space comprehensive positioning error value could be calculated by the formula calculation using the positioning error values in three directions.The mean values of the three-dimensional space positio-ning errors of the adjustable angle headstock group and domestic integrated plate group were 0.320 cm and 0.340 cm respectively,there was no statistically significant difference between the two groups.Conclusion The absolute error in Y direction and the median value of three-dimensional displacement of the CIVCO adjustable angle head rest are smaller than those of the domestic integrated plate,which is worthy of clinical promoted applica-tion if conditions permit.

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.

Objective To construct a model combining with traditional Chinese medicine(TCM)syndrome for predicting the risk of disease progression in patients with idiopathic membranous nephropathy(IMN)by machine learning methods,thus to quantitatively evaluating the value of TCM syndrome in the prediction of the risk of disease progression in IMN.Methods Monofactor analysis,recursive feature elimination(RFE)and multivariate binary Logistic regression analysis were used to screen the independent related factors affecting the risk of disease progression of IMN,and then a risk prediction model was constructed.A total of 102 patients with IMN were randomly assigned to the training set and the test set in a ratio of 65∶35,and then the comparison was conducted in the performance indicators of accuracy,sensitivity,specificity,F1 value,and area under the receiver operating characteristic(ROC)area under the curve(AUC)of the risk prediction model with or without the inclusion of the TCM syndrome information.Results Before the inclusion of TCM syndrome information,12 clinical characteristic variables for patients with MN were obtained after monofactor analysis combined with RFE screening,and they were age,hemoglobin quantification,urinary occult blood,24-hour urine protein quantification,urine protein-creatinine ratio,estimated glomerular filtration rate(eGFR),creatinine,uric acid,alanine transaminase,anti-phospholipase A2 receptor antibody(PLA2R-Ab),total cholesterol,and low-density lipoprotein cholesterd.A risk cholesterol prediction model containing the above variables was constructed.The multivariate binary Logistic regression analysis showed that the differences of the clinical variables mentioned above between the training-set group and test-set group were statistically significant,and the risk prediction model presented good sensitivity and predictability.Monofactor analysis combined with RFE screening was performed again after the inclusion of TCM syndrome information,and then 14 variables were obtained,which included blood stasis syndrome and dampness obstruction syndrome.The sensitivity and specificity of the model with the inclusion of the TCM syndrome information were significantly improved when compared with those without the inclusion of TCM syndrome information.Conclusion The results of the study initially indicate that TCM syndrome can be used as an important supplementary variable for predicting the risk of disease progression in IMN,and will provide a reference for intelligent diagnosis through the integration of traditional Chinese and western medicine information,and will supply the guidance for the treatment of IMN with TCM.

Objective:To explore the efficacy and safety of endovascular intervention combined with preoperative laparoscopic exploration in the treatment of patients with acute mesenteric artery ischemia.Methods:This was a prospective cohort study (NCT04686981). The study enrolled 31 patients with acute mesenteric artery ischemia from Oct 1, 2020 to Oct 1, 2022. Among them, 26 patients (84%) were male, with a mean age of (67±13) years and a mean time to onset of (21±8) hours. All patients underwent laparoscopic exploration in the hybrid operating room. If the presence of intestinal necrosis or suspected necrosis was clearly determined, the patient would undergo open surgery (mesenteric artery embolization, intestinal resection and intestinal double stoma) as the treatment by gastrointestinal surgeon. If intestinal necrosis or suspected necrosis was not found by laparoscopy, the patient would undergo endovascular intervention by vascular surgeon. The primary observational endpoints of this study were the proportion of patients who were not dependent on total parenteral nutrition and all-cause mortality within 30 days after operation. The secondary observational endpoints were the rate of mesenteric vascular patency within 30 days and the proportion of interventions that were converted to open surgery.Results:Six patients underwent open surgery and 25 patients underwent endovascular intervention, including 13 cases of thrombus reduction alone, 3 cases of stent implantation during the same period after reduction, and 9 cases of stent implantation alone. Twenty-four patients (77%) were completely weaned from the TPN within 30 days after the procedure, and all-cause mortality was observed in 3 cases (9.7%). The patency rate of the mesenteric artery within 30 days after the procedure was 82.1%. The rate of conversion to open surgery after intervention was 16%.Conclusions:Endovascular intervention combined with preoperative laparoscopic exploration can clarify intestinal ischemia in acute mesenteric patients as early as possible, and individualized treatment strategies for each patient by multidisciplinary care team can potentially improve the prognosis of such patients.
