OBJECTIVES: This study investigates independent risk factors for postoperative internal fixation device infection in patients with maxillofacial fractures and proposes an early warning model based on the synthetic minority over-sampling technique (SMOTE) algorithm. METHODS: A total of 1 104 patients who underwent surgical treatment for maxillofacial fractures at Oral and Maxillofacial Surgery Department, Affiliated Hospital of Nantong University from January 2021 to December 2024 were retrospectively analyzed. The patients were divided into two groups based on the presence of postoperative internal fixation device infection: the infection group (27 cases) and non-infection group (1 077 cases). Clinical data from both groups were collected and subjected to statistical analysis. Univariate and binary Logistic regression analysis were used to identify risk factors for postoperative internal fixation device infection in maxillofacial fractures. Subsequently, a Logistic regression model was established, and the dataset was improved based on the SMOTE algorithm to construct an early warning model with the improved dataset. The prediction performance of the models was compared and validated. RESULTS: Among the 1 104 patients who underwent surgical treatment for maxillofacial fractures, 27 cases of postoperative internal fixation device infections were identified, corresponding to an infection rate of 2.45% (27/1 104). Age, diabetes history, fracture severity, and oral hygiene status were all identified as risk factors for postoperative internal fixation device infections in maxillofacial fractures (all P<0.05). The prediction model based on the original data (P1). The prediction model based on the SMOTE algorithm (P2). Receiver operating characteristic (ROC) curve analysis shows that the area under curve (AUC) for the P2 model was 0.882, the P1 model was 0.861, indicating the superior predictive performance of the P2 model. The DeLong test results show that the difference in AUC between the two models was statistically significant (P<0.05). CONCLUSIONS Age, diabetes history, postoperative fracture severity, and oral hygiene status are all risk factors for infections associated with internal fixation devices after maxillofacial fracture surgery. The proposed early warning model demonstrated good predictive performance. Medical professionals can utilize this model to effectively intervene and anticipate infections related to internal fixation devices after maxillofacial fracture surgery.

The translation of genetic findings from genome-wide association studies into actionable therapeutics persists as a critical challenge in Alzheimer's disease (AD) research. Here, we present PI4AD, a computational medicine framework that integrates multi-omics data, systems biology, and artificial neural networks for therapeutic discovery. This framework leverages multi-omic and network evidence to deliver three core functionalities: clinical target prioritisation; self-organising prioritisation map construction, distinguishing AD-specific targets from those linked to neuropsychiatric disorders; and pathway crosstalk-informed therapeutic discovery. PI4AD successfully recovers clinically validated targets like APP and ESR1, confirming its prioritisation efficacy. Its artificial neural network component identifies disease-specific molecular signatures, while pathway crosstalk analysis reveals critical nodal genes (e.g., HRAS and MAPK1), drug repurposing candidates, and clinically relevant network modules. By validating targets, elucidating disease-specific therapeutic potentials, and exploring crosstalk mechanisms, PI4AD bridges genetic insights with pathway-level biology, establishing a systems genetics foundation for rational therapeutic development. Importantly, its emphasis on Ras-centred pathways-implicated in synaptic dysfunction and neuroinflammation-provides a strategy to disrupt AD progression, complementing conventional amyloid/tau-focused paradigms, with the future potential to redefine treatment strategies in conjunction with mRNA therapeutics and thereby advance translational medicine in neurodegeneration.

Objective To observe the therapeutic effect and mechanism of allicin on uremic-induced myocardial injury in rats.Methods Twenty-four rats were randomly divided into sham-operated group,model group,and low-,and high-dose allicin groups,with six rats in each group.Except for the sham-operated group,the uremic-induced myocardial injury model was constructed using the 5/6 nephrectomy method in all other groups of rats.After successful modeling,corresponding interventions were carried outed.At the end of the intervention,the renal function of rats was observed,the cardiac mass index was calculated,the levels of serum high-sensitive cardiac troponinⅠ(hs-cTnI)and creatine kinase isoenzyme(CK-MB)were detected by enzyme-linked immunosorbent assay(ELISA),the pathological changes of rat cardiac tissues were observed by hematoxylin-eosin(HE)staining,the changes of autophagosomes and autolysosomes were observed by transmission electron microscopy,and the protein expressions of PTEN-induced putative kinase 1(PINK1)and E3 ubiquitin protein ligase(Parkin)in myocardial tissues were detected by Western Blot.Results Compared with the sham-operated group,the serum creatinine(SCr),blood urine nitrogen(BUN),cardiac mass index,CK-MB and hs-cTnI in rats in the model group were elevated(P<0.05),the pathological damage of cardiac tissues were obvious,and the autophagosomes and autolysosomes were decreased,and PINK1 and Parkin protein expressions in myocardial tissues were decreased(P<0.05);compared with the model group,SCr,BUN,cardiac mass index,CK-MB and hs-cTnI in allicin low-and hogh-dose groups were decreased,the changes of pathological damage of cardiac tissues were relieved,the autophagosomes and autolysosomes were increased,and PINK1 and Parkin protein expressions in myocardial tissues were increased(P<0.05).Conclusion Allicin can reduce myocardial injury in uremic rats,and its mechanism may be related to the up-regulation of PINK1/Parkin-mediated mitochondrial autophagy.

Myocardial injury is the leading cause of death in uremic patients.PINK 1/Parkin-mediated mitochondrial autophagy is involved in the progression of myocardial injury.In recent years,pathogenic turbidity has been gradually accepted as a representative of a new type of toxic pathogens by the researchers of traditional Chinese medicine(TCM).This paper sorts out literature about pathogenic turbidity,analyzes the etiological and pathogenic characteristics of pathogenic turbidity,and suggests that the pathogenesis of uremia-induced myocardial injury can be more comprehensively clarified from the perspective of healthy-qi deficiency resulting in latent pathogenic turbidity.In the patients with uremia,the down-regulation of PINK1/Parkin causes the weakening of mitochondrial autophagy,which leads to the elevation of levels of reactive oxygen species(ROS)and inflammatory factors,and eventually causes the injury of myocardial cell.The above pathogenic mechanism is similar to the process of traditional Chinese medicine(TCM)in which the deficiency of the healthy-qi(in particular kidney deficiency)results in the production of the pathogenic turbidity(showing as dampness,blood stasis,phlegm,toxin and so on)and then causes the pathogenic turbidity hide in vessels and collaterals and gradually injure the heart vessels,and eventually results in the deficiency of heart vessels.The mitochondrial autophagy mechanism mediated by the PINK1/Parkin pathway is suitalbe for explaining the TCM pathogenesis of uremia-induced myocardial injury,characterized by healthy-qi deficiency resulting in latent pathogenic turbidity,and also is suitable for interpretating the principle of supporting healthy-qi to eliminate pathogenic turbidity for treating uremia-induced myocardial injury.Under the guidance of the theory of health y-qi deficiency and turbid pathogens in TCM,the development of specific PINK 1/Parkin agonists may expand the approach for the treatment of uremia-induced myocardial injury.
