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.

Renal lymphatic vessel density is clinically relevant in kidney disease but is still assessed by slow, subjective visual estimation. We evaluated a weakly supervised, attention-based multiple-instance learning framework for automated detection and quantification of renal lymphatic vessel density on D2-40-stained whole-slide images (WSIs). Methods: Two independent internal datasets from Tongji Hospital were collected, including 198 cases of chronic kidney disease (CKD) and 50 cases of hypertensive nephropathy (HTN). All biopsies were immunohistochemically stained for D2-40 and digitized as WSIs. Pathologists provided only slide-level labels (D2-40 high vs. D2-40 low). Tissue regions were automatically segmented, tiled into patches, and encoded using a pretrained convolutional neural network. Patch embeddings were then analyzed with a clustering-constrained attention multiple-instance learning (CLAM) model. Unlike conventional multiple-instance learning (MIL) methods that only weight instances, CLAM jointly performs attention-based instance selection and instance-level clustering to distinguish positive from negative evidence within each slide, yielding more discriminative slide-level features and interpretable attention maps. Performance was compared with a classic MIL model trained on the same features. Results: CLAM achieved area under the receiver operating characteristic curves of 0.942 and 0.858 on the CKD and HTN datasets, respectively, outperforming classic MIL (0.866 and 0.801). Attention maps highlighted lymphatic-rich regions consistent with renal pathologists’ assessments. Conclusions: This clustering-constrained, attention-based weakly supervised framework enables fully automated, reproducible quantification of renal lymphatic vessel density from WSIs, providing renal pathologists with rapid visual and numerical support for diagnosis and risk stratification in CKD and HTN.

Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

BACKGROUND:The reasonable implantation range of femoral prosthesis in unicompartmental knee arthroplasty in patients with osteoporosis has not been investigated,and previous studies have often been based on unicompartmental knee arthroplasty models in normal bone,with fewer mechanical studies in models with non-normal bone.Complications after unicompartmental knee arthroplasty have been shown to be highly associated with osteoporosis. OBJECTIVE:To analyze the biomechanical effects of the coronal inclination of the Sled fixed platform femoral prosthesis on unicompartmental knee arthroplasty in patients with osteoporosis and to find the correlation between osteoporosis and mid-and long-term complications after unicompartmental knee arthroplasty. METHODS:Based on the digital imaging technology to obtain the data of the knee joint and prosthesis,a normal bone knee model is then created by using specialized software such as Mimics and Geomagic studio.Based on a validated normal bone knee model,an osteoporotic knee model was created by changing the material parameters.Totally 14 unicompartmental knee arthroplasty finite element models were created using Sled fixed platform femoral prosthesis:standard position(0°),varus and valgus angles:3°,6°,9° in the normal bone and osteoporosis groups.Stress changes on the surface of polyethylene liner,cancellous bone under tibial prosthesis,and cortical bone were calculated and analyzed in all unicompartmental knee arthroplasty models. RESULTS AND CONCLUSION:(1)In the osteoporotic models,the high stress values of the polyethylene liner surface and the cancellous bone under the tibial prosthesis increased with the increase of the tilt angle of the femoral prosthesis,and the high stress values of the cortical bone surface under the tibial prosthesis increased with the increase of the prosthesis valgus angles and decreased with the increase of the varus angles.(2)For the polyethylene liner surface as well as the subcortical bone surface of the tibial prosthesis,the high stress values of the models for each inclination angle in the osteoporosis group were greater than those of the corresponding models in the normal bone group.For the surface of the cancellous bone under the tibial prosthesis,the high stress values of the tilt angle models of the osteoporosis groups were smaller than those of the normal bone groups.(3)Osteoporosis may cause biomechanical abnormalities in the internal structures of the knee after unicondylar replacement,increasing the potential risk of postoperative aseptic loosening of the prosthesis and periprosthetic fractures.Varus and valgus of the femoral prosthesis in the coronal plane should be avoided as much as possible when performing medial unicompartmental knee arthroplasty with a Sled fixation platform in osteoporotic knees.

BACKGROUND:Previous studies have demonstrated that moxibustion can alleviate osteoarthritis-induced cartilage lesions and delay the progression of knee osteoarthritis. In a previous study conducted by our research group,it was found that regulating the circPan3/miR-667-5p/Ghrelin signaling pathway can enhance the level of autophagy in chondrocytes,thereby exerting a cartilage protective role in knee osteoarthritis. OBJECTIVE:To explore the effect of moxibustion on knee osteoarthritis cartilage in rats based on the circPan3/miR-667-5p/Ghrelin signaling pathway. METHODS:Sprague-Dawley rats were randomly divided into three groups (n=10 per group):sham operation,model,and moxibustion groups. A rat model of knee osteoarthritis was established in the latter two groups by anterior cruciate ligament transection and medial meniscus resection. Rats in the sham operation group underwent arthrotomy only. At 6 weeks after modeling,moxibustion intervention at Zusanli and Shenyu acupoints was applied in the moxibustion group,20 minutes daily for 4 weeks,while the other two groups did not receive any special treatment. After 4 weeks,histopathological staining was performed to observe the degree of synovial lesions and cartilage damage in the knee joint. Additionally,changes in the serum levels of inflammatory cytokines,interleukin-6 and tumor necrosis factor-α,were detected by enzyme-linked immunosorbent assay. Furthermore,chondrocytes isolated from the above three groups of rats were divided into three groups:a normal control group,a model group,and a moxibustion group. The expression levels of cartilage matrix anabolic molecules (type Ⅱ collagen and Sox9),matrix degradation molecules (matrix metalloproteinase 13 and ADAMTS5),autophagy markers (ATG5,Beclin-1,microtubule-associated protein 1 light chain 3),Ghrelin,CircPan3,and miR-667-5P were determined by western blot and qRT-PCR in each group. RESULTS AND CONCLUSION:After 4 weeks of treatment,the model group exhibited significant thickening of the synovium,infiltration of inflammatory cells,narrowing of the joint space,rough and uneven cartilage surfaces,thinning,reduction in the number of chondrocytes,a significant increase in synovitis and Osteoarthritis Research Society International scores,and a significant up-regulation of interleukin-6 and tumor necrosis factor-α levels (P<0.0001). In comparison,the sham operation group showed no significant changes. Compared with the model group,the moxibustion group exhibited a reduction in synovial thickening,a decrease in inflammatory cell infiltration,an increase in joint space,a reduction in cartilage roughness and loss of integrity,an increase in the number of chondrocytes,a reduction in synovitis and Osteoarthritis Research Society International scores,and a significant reduction in the levels of interleukin-6 and tumor necrosis factor-α (P<0.0001). The results of in vitro experiments demonstrated that the expression of matrix metalloproteinase 13,ADAMTS5,and miR-667-5P was elevated,while the expression of type Ⅱ collagen,Sox9,autophagy markers,Ghrelin,and Circpan3 was reduced in the model group compared with the normal control group (P<0.01). Moxibustion was found to reverse these changes in the moxibustion group compared with the model group (P<0.01). To conclude,moxibustion may enhance chondrocyte autophagy by modulating the circPan3/miR-667-5p/Ghrelin signaling pathway,which may inhibit knee osteoarthritis inflammation and cartilage destruction,exerting a protective effect on cartilage.

This research aims to construct a stable epithelial cell senescence model for screening and e-valuation of senolytics.We explored the optimal conditions for doxorubicin-induced senescence of non-transformed epithelial cells MCF 10A,including the optimal induction concentration,the optimal inter-vention time,and the optimal senescence duration,and confirmed the feasibility of MCF 10A as an epi-thelial senescence model by multiple ways.The optimal condition for Doxorubicin-induced senescence of MCF 10A cells was treatment with 0.6 μmol/L Doxorubicin for 16 h to achieve the best senescence state on the 8th day.Under the optimal induction conditions,the positive rate of senescence-associated β-gal-actosidase(SA-β-gal)staining in the treated group reached 97%.At the same time,biochemical results of detecting the expression of mRNA,proteins,and immunofluorescence demonstrated that the expression levels of senescence-associated secretory phenotype(SASP),p16,p21 and p53 in the treated group were significantly higher than those in the control cells,and Lamin B1 was significantly decreased(P<0.001),which were consistent with the specific characteristics of senescence.In summary,an epithelial senescence model was successfully induced in MCF 10A cells by Doxorubicin in this study,which will promote the screening of senolytics for senescent epithelial cells.

Objective:
To explore the causal link of cumulative ecological risk and future orientation with health risk behaviors among higher vocational college students, so as to provide reference for reducing and preventing health risk behaviors among higher vocational college students.
Methods:
A longitudinal follow up study was conducted on 612 students using convenience sampling from 2 vocational colleges in Hunan Province. The Cumulative Ecological Risk Scale, Future Orientation Scale, and Health Risk Behavior Scale were used during three follow up visits (T1: September 2022, T2: June 2023, T3: March 2024), and a cross lagged panel model was constructed to examine the longitudinal causal relationship of cumulative ecological risk, future orientation and health risk behaviors. Analysis of longitudinal intermediary effect between variables by Bootstrap.
Results:
The cumulative ecological risk scores of T1, T2 and T3 among higher vocational college students were (2.94±1.44,2.99±1.63,3.02±1.54), future orientation scores (40.49±4.71,41.51±5.72,41.06±4.35) and health risk behavior scores (3.73±2.01,3.49±2.00,3.23±2.00). The results of repeated measures ANOVA showed that the future orientation score of T2 was higher than that of T1, and the main effect of measurement time was statistically significant ( F=5.09,P<0.01,η 2=0.02). The health risk behavior score of T1 was higher than that of T2, and the health risk behavior score of T2 was higher than that of T3, and the main effect of measurement time was statistically significant ( F=10.12,P<0.01,η 2=0.03).The cross lagged model showed good adaptability, with χ 2/df =7.20 ( P <0.01), relative fitting indicators GFI=0.98, CFI=0.99, TLI=0.96, IFI=0.99, NFI =0.99, and absolute fitting indicator RMSEA =0.06. Among them, the T1, T2 cumulative ecological risk showed negatively predictive effects on T2, T3 future orientation ( β =-0.24, -0.47 ), and T1, T2 cumulative ecological risk positively predicted T2, T3 health risk behavior ( β =0.20, 0.24), while T1, T2 future orientation negatively predicted T2, T3 health risk behavior ( β =-0.25, -0.18) ( P <0.01). Bootstrap test analysis found that T2 future orientation had a longitudinal mediating effect ( β=0.04, P <0.01) on the T1 cumulative ecological risk and T3 health risk behavior.
Conclusions
The accumulation of ecological risk among higher vocational college students can positively predict health risk behaviors, while future orientation can negatively predict healthrisk behaviors. Moreover, future orientation plays a longitudinal mediating role between accumulated ecological risks and health risk behaviors.
