ObjectiveTo investigate the influencing factors and independent risk factors for lower extremity deep vein thrombosis (DVT) in patients with acute necrotizing pancreatitis (ANP), to analyze the effectiveness of three commonly used risk assessment models for thrombosis (Caprini score, Padua score, and Wells score), and to provide a reference for clinical identification of high-risk individuals and optimization of prevention and treatment strategies. MethodsA retrospective analysis was performed for the clinical data of 320 patients with ANP who were admitted to Luzhou People’s Hospital and The Affiliated Hospital of Southwest Medical University from April 2013 to April 2024, and according to the presence or absence of DVT during hospitalization, the patients were divided into thrombosis group with 25 patients and control group with 295 patients. After propensity score matching, the two groups were compared in terms of past history and various examination results during hospitalization. The risk factors for lower extremity DVT in ANP patients during hospitalization were analyzed through univariate and multivariate Logistic regression, and a DVT risk prediction model was established based on independent influencing factors. The receiver operating characteristic (ROC) curve was used to assess the performance of models, and the DeLong test was used for comparison of the area under the ROC curve (AUC), sensitivity, and specificity. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. ResultsAfter matching, the patients were divided into thrombosis group with 24 patients and control group with 112 patients. The clinical characteristics analysis showed that compared with the control group, the thrombosis group had significantly higher degree of pancreatic necrosis, D-dimer level, Bedside Index for Severity in Acute Pancreatitis (BISAP) score, and proportion of patients undergoing dialysis (all P<0.05). The multivariable Logistic regression analysis showed that BISAP score, degree of pancreatic necrosis, and D-dimer level were independent risk factors for lower extremity DVT in ANP patients during hospitalization (all P<0.05). The BISAP-Caprini score model had an AUC of 0.832 (95% confidence interval: 0.722 — 0.942, P<0.001) in predicting the risk of lower extremity DVT, with a Youden index of 1.661, an optimal cut-off value of 0.26, a sensitivity of 75.0%, and a specificity of 91.1%. ConclusionD-dimer, BISAP score, and the degree of pancreatic necrosis are independent risk factors for lower extremity DVT in patients with ANP during hospitalization, and the BISAP-Caprini score model can effectively predict the risk of DVT in ANP patients.

Objective: To investigate the impact of RhE antigen-matched transfusion during liver transplantation on early postoperative recovery and complications. Methods: In this retrospective cohort study, ninety-five patients undergoing liver transplantation at Kunming First People's Hospital between January 2022 and July 2025 were enrolled. Patients were divided into two groups: Group 1 (RhE-mismatched transfusion, n=57) and Group 2 (RhE-matched transfusion, n=38). The baseline data, complete blood counts, hepatic and renal function, coagulation parameters, and complication rates between the two groups were compared at postoperative days 1, 3, 5, 7, and 10. Survival analysis was performed using the Kaplan-Meier method. Results: The baseline characteristics were well-balanced and comparable between the two groups (all P>0.05). The early postoperative mortality rate in the mismatched group (31.58%, 18/57) was significantly higher than that in the matched group (10.53%, 4/38) (P=0.017). The incidence of postoperative hepatic encephalopathy was significantly higher in the mismatched group (50.88%, 29/57) than in the matched group (10.53%, 4/38) (P<0.001). The incidence of postoperative haemorrhage in the mismatched group (24.56%, 14/57) was higher than that in the matched group (5.26%, 2/38), with a statistically significant difference (P=0.014). The incidence of perioperative infection in the mismatched group (28.07%, 16/57) was higher than that in the matched group (10.53%, 4/38), with a statistically significant difference (P=0.04). Corresponding odds ratios (OR) and 95% confidence intervals indicated a lower risk of these adverse events in the matched group. On postoperative day 1, the change in activated partial thromboplastin time (-1.6, 20.5) in the mismatched group was greater than in the matched group (-0.2, 5.5). The change in international normalised ratio (-0.56, 1.22) in the mismatched group was greater than in the matched group (-0.18, 0.32), while the change in albumin (-4.0, 4.8) was smaller in the mismatched group than in the matched group (-2.5, 8.8). On postoperative day 5, the change in albumin (-0.41±7.83) in the mismatched group was smaller than in the matched group (2.68±4.53). At postoperative day 7, the change in albumin in the mismatched group (-0.61±7.38) was smaller than that in the matched group (2.51±5.85), while the change in D-dimer in the mismatched group (0.73, 7.4) was greater than that in the matched group (-1.6, 4.3). On postoperative day 10, the mismatched group exhibited significantly higher fibrinogen levels (-1.21, 1.78) than the matched group (-0.49, 0.97), and significantly longer prothrombin times (-11.3, -2.7) than the matched group (-6.2, -0.8) (all P<0.05). The matched group exhibited a mean overall survival (OS) of 32.803 months (95% CI:29.171-36.436 months), significantly exceeding the mismatched group's 28.996 months (95% CI:24.202-33.790 months). The log-rank test yielded statistically significant results (χ
=4.307, P=0.038). Conclusion: Implementing RhE blood group-matched transfusion during liver transplantation may help reduce early postoperative mortality and the incidence of major complication rates, promote faster recovery of coagulation and liver function, and thereby improve short-term patient outcomes.

ObjectiveTo investigate the mechanism by which Wumeiwan suppresses the development and progression of colorectal cancer(CRC) through the regulation of fatty acid metabolic reprogramming, thereby providing new experimental evidence for the prevention and treatment of CRC. MethodsA total of 120 C57BL/6 mice were randomly divided into the blank group, model group, Wumeiwan high-, medium-, and low-dose groups(54, 27, 13.5 g·kg-1), and the mesalazine group(0.01 g·kg-1), with 20 mice in each group. Except for the blank group, all mice were subjected to azoxymethane(AOM)/dextran sulfate sodium(DSS) treatment to establish an inflammation-associated CRC model. One week after AOM injection, mice in the treatment groups received intragastric administration of the designated drugs, while the blank and model groups received an equal volume of purified water, continuing until 20 d after the intervention endpoint. Hematoxylin-eosin(HE) staining was used to observe colonic histopathological alterations, and immunohistochemistry for vascular endothelial growth factor(VEGF) was performed to evaluate neovascularization and tumor invasion. Metabolomics combined with Kyoto Encyclopedia of Genes and Genomes(KEGG) and metabolite set enrichment analysis(MSEA) was applied to identify key CRC-related metabolic pathways, which were further validated by transcriptomic Gene Ontology(GO) enrichment and gene heatmap analysis. Subsequently, Western blot was performed to determine the expression levels of core proteins in these pathways, and immunofluorescence was used to analyze their localization and co-expression patterns in tissues, thereby elucidating the mechanism of Wumeiwan from multiple biological dimensions. ResultsCompared with the blank group, mice in the model group exhibited a significant decrease in body weight and a significant increase in the disease activity index(DAI) score(P<0.05), with pronounced colonic mucosal damage accompanied by aggravated tumor invasion. Compared with the model group, Wumeiwan intervention markedly improved body weight loss and reduced DAI score, attenuated mucosal injury, and significantly decreased VEGF expression level(P<0.05). Multi-omics analysis revealed that differential metabolites and genes across groups were commonly enriched in fatty acid metabolism, fatty acid biosynthesis, and other lipid-related pathways. Relative to the blank group, the model group showed significant upregulation levels of fatty acid synthesis-related genes, including sterol regulatory element-binding protein 1(SREBP1), fatty acid synthase(FASN), stearoyl-CoA desaturase 1(SCD1), as well as saturated fatty acids(P<0.05). Compared with the model group, treatment with Wumeiwan significantly reduced the expression of key genes involved in fatty acid metabolic pathways, including SREBP1, FASN, and SCD1(P<0.05). Western blot results further confirmed that proteins in this pathway were significantly elevated in the model group, whereas they were markedly downregulated following Wumeiwan treatment(P<0.05). Immunofluorescence analysis demonstrated enhanced co-localization of SREBP1 with the cancer-associated fibroblast(CAF) marker α-smooth muscle actin(SMA) in the model group, whereas this co-localization signal was attenuated after Wumeiwan intervention(P<0.05). ConclusionWumeiwan can improve survival outcomes and alleviate colonic pathological damage in CRC mice, its therapeutic mechanism may be closely associated with the regulation of fatty acid metabolic reprogramming mediated by the SREBP1/FASN/SCD1 signaling pathway.

Objective To investigate the role and potential mechanism of secreted phosphoprotein 1 (SPP1)+ macrophages in the formation of chronic renal allograft fibrosis. Methods The expression features of SPP1+ macrophages in renal allografts of chronic allograft dysfunction (CAD) patients were analyzed based on single-cell transcriptome data of renal tissues from patients with CAD. Transcription factor VIPER analysis and DoRothEA transcription factor activity analysis were performed on the single-cell transcriptome data. Renal tissue samples were collected from kidney transplant recipients, including the CAD group (n=5) and the non-renal allograft fibrosis group (CTL group, n=5). A mouse model of chronic allograft rejection was established and divided into the allogeneic kidney transplantation group (CAD group, n=3) and the syngeneic kidney transplantation group (SYN group, n=3). Hematoxylin-eosin staining was used to detect renal tissue injury in mice, and Masson staining was used to detect renal tissue fibrosis. Immunofluorescence staining was performed to detect SPP1 expression in renal tissues of transplant recipients and mouse renal allografts. Bone marrow-derived macrophages (BMDMs) were extracted from mice and subjected to hypoxia stimulation. The expression of hypoxia-inducible factor (HIF)-1α and SPP1 was detected by Western blot, and SPP1 expression was detected by flow cytometry. BMDMs were transfected with HIF-1α overexpression plasmid and HIF-1α small interfering RNA (siRNA) followed by hypoxia intervention, and the expression of HIF-1α and SPP1 was detected by Western blot. Mouse aortic endothelial cells (MAECs) were co-cultured with the supernatant of BMDMs, and the expression of endothelial-mesenchymal transition (EndMT)-related markers was detected by Western blot and immunofluorescence. Results Single-cell transcriptome analysis showed that the proportion of SPP1+ macrophages in renal allograft tissues was significantly higher in the CAD group than in the CTL group (P<0.05). The renal injury score and the percentage of interstitial fibrotic area in the CAD group were significantly higher than those in the SYN group (both P<0.05). Immunofluorescence staining showed that the proportion of SPP1+ macrophages was increased in the CAD group compared with the CTL group, and also increased in the CAD group compared with the SYN group (both P<0.05). VIPER analysis and DoRothEA transcription factor activity analysis revealed activation of the hypoxia pathway and upregulated expression of transcription factors such as HIF-1α in SPP1+ macrophages. SPP1 expression was elevated in BMDMs under hypoxic conditions. Knockdown of HIF-1α inhibited hypoxia-induced SPP1 protein expression, whereas overexpression of HIF-1α upregulated SPP1 protein levels. After co-culture of hypoxia-induced BMDMs with MAECs, the expression levels of EndMT-related markers were increased. Conclusions SPP1+ macrophages differentiated under hypoxia are significantly infiltrated in the formation of chronic renal allograft fibrosis, and may promote renal allograft fibrosis by inducing EndMT in renal vascular endothelial cells.

The blood-brain barrier (BBB) is a physical and biochemical barrier that precisely regulates brain homeostasis and plays a central role in controlling the transport of endogenous and exogenous drugs and related metabolites across the blood-brain interface. These functions of the BBB are mediated by its major components, including brain microvascular endothelial cells (BMECs), tight junction protein complexes, and influx and efflux transporter proteins. One of the pathological features of ischemic stroke (IS) is BBB disruption, which plays an important role in the development of post-stroke brain injury and subsequent neurological dysfunction. Therefore, given the increasing incidence of IS, there is an urgent need to develop new therapeutic strategies to prevent BBB dysfunction and thereby protect injured brain tissue after IS. This study describes the pathological mechanisms by which BMEC injury after IS leads to BBB dysfunction and elucidates the association between BMECs and IS, including the regulation of apoptosis, autophagy, inflammatory responses, oxidative stress, neurotoxic effects, and cerebral edema. In addition, this article summarizes Chinese herbal medicines that may prevent and treat IS by targeting BMECs. These include monomeric compounds and single herbs such as flavonoids, glycosides, phenols, phthalides, terpenoids, and Styrax. Traditional Chinese medicine (TCM) compound formulas and preparations include oral formulations such as Buyang Huanwu decoction, Sailuotong, Naoxintong capsules, Dandeng Tongnao capsules, and Shexiang Tongxin dropping pills, as well as injectable preparations such as Tongluo Jiunao injection, Xingnaojing injection, Danshen polyphenolic acid for injection, Yiqi Fumai injection, and Shuxuetong injection. This study aims to explore the protective effects of TCM against IS through targeted regulation of BMEC function, providing new insights into the mechanisms of IS and endovascular therapeutic strategies.

Objective To systematically evaluate the efficacy and safety of proximal gastrectomy (PG) versus total gastrectomy (TG) for the treatment of Siewert type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction (AEG). Methods PubMed, The Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, and VIP databases were searched for literature comparing the efficacy and safety of PG and TG for the treatment of Siewert type Ⅱ/Ⅲ AEG. The search period was from database inception to March 2023. Meta-analysis was performed using Review Manager 5.4 software. Results A total of 23 articles were included, including 16 retrospective cohort studies, 5 prospective cohort studies, and 2 randomized controlled trials. The total sample size was 2 826 patients, with 1 389 patients undergoing PG and 1 437 patients undergoing TG. Meta-analysis results showed that compared with TG, PG had less intraoperative blood loss [MD=−19.85, 95%CI (−37.20, −2.51), P=0.02] and shorter postoperative hospital stay [MD=−1.23, 95%CI (−2.38, −0.08), P=0.04]. TG had a greater number of lymph nodes dissected [MD=−6.20, 95%CI (−7.68, −4.71), P<0.001] and a lower incidence of reflux esophagitis [MD=3.02, 95%CI (1.24, 7.34), P=0.01]. There were no statistically significant differences between the two surgical approaches in terms of operative time, postoperative survival rate (1-year, 3-year, 5-year), and postoperative overall complications (P>0.05). Conclusion PG has advantages in terms of intraoperative blood loss and postoperative hospital stay, while TG has advantages in terms of the number of lymph nodes dissected and the incidence of reflux esophagitis. There is no significant difference in long-term survival between the two surgical approaches.

Objective To investigate the clinical value of 3.0 T functional magnetic resonance imaging in evaluating postoperative recurrence and treatment efficacy of glioma. Methods A retrospective analysis was conducted on the general clinical data of 67 patients who underwent glioma surgery at the Second Affiliated Hospital of Xingtai Medical University. All patients received chemotherapy for more than one month post-surgery. Recurrence of glioma was diagnosed based on secondary surgery or pathological biopsy results as the gold standard. From 3 to 6 months post-surgery, computerized tomography was used to measure cerebral blood volume (CBV), three-dimensional arterial spin labeling was used to measure cerebral blood flow (CBF) and relative CBF (rCBF), and diffusion-weighted imaging with and without contrast enhancement was used to measure apparent diffusion coefficient (ADC). Data were analyzed using SPSS 26.0 statistical software, and the t test or χ2 test was used for inter-group comparisons based on data type. The receiver operating characteristic (ROC) curve was applied to evaluate the value of CBV, rCBF, and ADC in assessing postoperative recurrence and treatment efficacy of glioma. Results Patients with high-grade gliomas showed significantly higher CBV and rCBF and significantly lower ADC compared to those with low-grade gliomas (P < 0.05). The area under the ROC curve (AUC) of CBV, rCBF, and ADC in combination for grading glioma was 0.960, which was higher than those of individual indicators (0.790, 0.955, and 0.795, P < 0.05). The recurrence group had significantly higher CBV and rCBF and lower ADC compared to the non-recurrence group (P < 0.05). The AUC of CBV, rCBF, and ADC in combination for predicting postoperative glioma recurrence was 0.965, which was significantly higher than those of individual indicators (0.729, 0.929, and 0.941, P < 0.05). CBV and rCBF were lower and ADC was higher in the effective treatment group than in the ineffective treatment group (P < 0.05). The AUC of CBV, rCBF, and ADC in combination for evaluating glioma treatment efficacy was 0.985, which was higher than those of individual indicators (0.842, 0.898, and 0.961, P < 0.05). Conclusion The CBV, rCBF, and ADC in combination has shown high diagnostic accuracy and predictive efficacy in the evaluation of postoperative recurrence and treatment efficacy of glioma, which has important clinical application value.

This article systematically reviews and verifies the historical evolution of Stemonae Radix from the aspects of name, origin, harvesting and processing, quality and others by consulting ancient and modern literature, in order to provide reference for the development and utilization of famous classical formulas containing this medicinal herb. Stemonae Radix has a long history of application, and it derives its name from its distinctive growth pattern, featuring clusters of ten to several dozen underground tuberous roots. This morphology resembles that of certain plants in the genus Asparagus, leading to historical instances where tuberous roots from genus Asparagus were mistakenly used as Stemonae Radix. After the research, it can be concluded that Stemonae Radix was first recorded in Mingyi Bielu, and throughout history, Baidu has been recognized as its official name, though it also bears alternative names such as Baibing, Pofucao and Ye Tianmendong. The mainstream sources used throughout history have been the dried tuberous roots of Stemona sessilifolia, S. japonica or S. tuberosa from the family Stemonaceae. This aligns with the 2025 edition of Pharmacopoeia of the People's Republic of China(hereinafter referred to as Chinese Pharmacopoeia). Additionally, Asparagus filicinus and A. officinalis from the genus Asparagus are common sources of confusion with Stemonae Radix. The three primitive plants are mainly distributed in the Yangtze River basin and southern China, exhibiting a wide distribution. Historically, wild harvesting was predominant, but cultivation is now established. In ancient times, the harvesting time was mostly in the second, third, and eighth lunar months, when roots were harvested and dried. Nowadays, it is more common to pick and excavate in the spring and autumn seasons. After excavation, the roots are washed, fibrous roots removed, briefly blanched in boiling water or steamed until no white core remains, and then sun-dried or oven-dried. In ancient times, the processing of Stemonae Radix primarily involved roasting(stir-frying), wine roasting, or raw materials. Modern mainstream processing specifications include two types of raw and honey-roasted products. In terms of quality evaluation of the medicinal materials, ancient criteria of "preferring plump and moist roots" align with modern requirement favoring "thick, robust stems with firm texture". Evaluating quality with authenticity, since the Song dynasty, it has been highly praised to produce in Chuzhou and Hengyang as the best. It was an ancient method of fixing the production area to stabilize the medicinal origin, reflecting the ancient recognition of the therapeutic efficacy of plants belonging to the genus Stemona. The main functions of Stemonae Radix remain consistent throughout history, including relieving coughs, eliminating phlegm and parasites. Based on the research results, it is recommended that when developing famous classical formulas containing the medicinal material Stemonae Radix, the botanical source specified in the 2025 edition of Chinese Pharmacopoeia should be selected. The specific species can be determined according to the distribution of resources and the main production areas, and the origin and corresponding botanical source should be fixed. Processing methods should be chosen based on the prescription requirements. It is recommended to use raw products without specified requirements.
