Hepatocellular carcinoma （HCC） with biliary duct tumor thrombus （BDTT） is currently not common in clinical practice and is easily misdiagnosed， and previously， it was often considered an advanced stage of the disease with a poor prognosis， making its treatment challenging. However， in-depth studies in recent years have gradually deepened our understanding of this disease， leading to significant changes in diagnostic and treatment concepts. Currently， comprehensive treatment， mainly surgery， is used for treatment， but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis， in order to provide a reference for clinical treatment options.

Objective:To construct a nomogram model for predicting the incidence of hepatocellular carcinoma based on serum abnormal prothrombin and alpha-fetoprotein and evaluate the predictive effect.Methods:Retrospective analysis of data from 351 patients with liver disease who received treatment at the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2023, including 285 males and 66 females, aged (52.9±11.9) years. Among the 351 patients, there were 229 cases (65.2%) of hepatocellular carcinoma, 87 cases (24.8%) of liver cirrhosis, and 35 cases (10.0%) of chronic hepatitis B. All patients were randomly divided into a training set ( n=245) and a testing set ( n=106) in a 7∶3 ratio without replacement sampling. The training set was used to construct the model, and the testing set was used to evaluate the model. At the same time, gender, age, disease type, and other indicators were compared between the two sets. The risk factors of hepatocellular carcinoma were analyzed by univariate and multivariate logistic regression based on the training set, and a nomogram was constructed to predict the incidence of hepatocellular carcinoma based on the multivariate results. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive performance of nomogram, and decision curve analysis was used to evaluate the clinical applicability of the model. Results:There was no statistically significant difference in age, gender, disease type, etc. between the training and testing sets of patients (all P>0.05). Univariate logistic regression analysis showed that age, abnormal prothrombin logarithm (LnPIVKA-Ⅱ), alpha-fetoprotein logarithm (LnAFP), and diabetes were associated with hepatocellular carcinoma (all P<0.05). Multivariate logistic regression analysis showed that older age ( OR=1.07, 95% CI: 1.03-1.12), higher LnPIVKA-Ⅱ ( OR=2.97, 95% CI: 1.97-4.46), higher LnAFP ( OR=1.43, 95% CI: 1.11-1.84) and diabetes ( OR=5.17, 95% CI: 1.02-26.17) were risk factors for hepatocellular carcinoma (all P<0.05). Based on the above variables, a nomogram model for predicting the incidence of hepatocellular carcinoma was constructed. The area under the ROC curve analysis of the nomogram for predicting the incidence of hepatocellular carcinoma was 0.920 (95% CI: 0.886-0.953) in the training set and 0.934 (95% CI: 0.891-0.977) in the testing set. The calibration curve fit well with the standard curve, and the prediction was basically consistent with the actual situation. The decision curve analysis showed that the net benefit of the model was greater than 0 under most thresholds (0.1-1.0). Conclusion:The nomogram constructed based on age, LnPIVKA-Ⅱ, LnAFP and diabetes can effectively predict the incidence of hepatocellular carcinoma and has clinical applicability.

Periodontitis, a common chronic inflammatory disease, progressively damages the supporting tissues of teeth, ultimately resulting in tooth loss. The rising incidence of periodontitis in adults has prompted researchers to observe a frequent co-occurrence of mental health disorders (such as anxiety disorders, depression disorders) in patients undergoing periodontitis onset and treatment. The existence of severe periodontitis can even aggravate the mental and psychological disorders of patients. Furthermore, the long-term fast-paced, high-pressure modern life is easy to cause a series of psychological problems, in turn affecting the occurrence and development of periodontitis. At present, researchers have reported the correlation between periodontitis and anxiety disorders/depression disorders. However, due to the lack of systematic understanding, most of them are clinical investigations or epidemiological statistics without deep mechanism studies. In view of the above problems, this article elucidates the bidirectional relationship between periodontitis and depression/anxiety disorders in recent years by examining recent epidemiological findings, exploring potential bidirectional pathogenic mechanisms, and discussing current treatment strategies. Ultimately, this review seeks to provide new perspectives for improving both oral and mental health outcomes in patients affected by periodontitis and anxiety/depression disorders.

Objective To explore the correlation between the diameter of patients'autologous tendon and the prognosis of anterior cruciate ligament(ACL)reconstruction surgery.Methods From October 2018 to October 2023,82 patients who underwent anterior cruciate ligament reconstruction surgery at Wuxi No.904 Hospital were selected.Based on whether complications occurred after the anterior cruciate ligament reconstruction surgery,they were divided into a group with good prognosis(n=64)and a group with poor prognosis(n=18).Performing univariate analysis on the prognosis of anterior cruciate ligament reconstruction surgery.Pearson correlation analysis was used to analyze the relationship between tendon diameter and prognosis.A multifactorial Logistic regression model was applied to analyze the factors influencing the prognosis of ACL reconstruction and construct a nomogram.The diagnostic efficacy of tendon diameter on the prognosis of ACL reconstruction was analyzed using the receiver operating characteristic(ROC)curve.Results The results of the univariate analysis showed that there were statistically significant differences in gender and age between the two groups(P＜0.05).The tendon diameter and cross-sectional area in the group with a good prognosis were higher than those in the group with a poor prognosis(P＜0.05).Post-treatment,the Lysholm,Tegner,and IKDC scores in the group with a good prognosis were higher than those in the group with a poor prognosis(P＜0.05).Pearson correlation analysis showed a significant positive correlation between the patient's tendon diameter and Lysholm,Tegner,and IKDC scores(r=0.417,0.411、0.446,P＜0.05).Logistic analysis indicated that gender,age,tendon diameter,and tendon cross-sectional area are factors affecting the prognosis of ACL reconstruction(P＜0.05).The ROC curve results showed that the combined diagnostic effect of gender,age,tendon diameter,and cross-sectional area is significantly better than any single factor alone.Conclusion There is a significant correlation between the patient's autologous tendon diameter and the prognosis of ACL reconstruction surgery.An increase in autologous tendon diameter enhances knee joint function and improves patient prognosis.

Based on high-resolution magnetic resonance tube wall imaging,reverse medical engineering modeling techniques are used to obtain individualized intracranial artery models of high prevalence in ischemic stroke.Three types of intracranial artery models,including Newtonian fluid model,non-Newtonian fluid model and non-Newtonian fluid with two-phase flow model,are established for transient numerical simulations using computational fluid dynamics method.The hemodynamic parameters such as blood flow field,wall shear stress distribution and erythrocyte volume distribution are analyzed to investigate the possible mechanisms involved in the formation and progression of intracranial atherosclerosis.It is found that blood flow velocity increased significantly at the end of the internal carotid artery and the middle cerebral artery.Low-speed vortex flow and disturbed flow appear in the local vessels.The difference in blood flow velocity between the center and the edge of the wall is large,with an obvious low-flow velocity area on the outer side.A clear central core area is formed in the stenotic wall under the action of high-speed blood flow,resulting in thinner edge layer and lower erythrocyte volume fraction.The combination of low erythrocyte distribution in the edge layer and low flow velocity on the outer side of the wall exacerbates endothelial cell necrosis,hypoxia,endothelial dysfunction,and leads to atherosclerosis.Compared with Newtonian and non-Newtonian fluid models,non-Newtonian fluid with two-phase flow model has greater variability for hemodynamic parameters and shows higher fidelity in simulating blood flow,which provides a reference for clinical diagnosis and treatment of cerebrovascular diseases.
