ObjectiveThis study aims to develop a prediction model for the compatibility of Chinese medicinal pairs based on Graph Convolutional Networks (GCN), named HC-GCN. The model integrates the properties of herbs with modern pharmacological mechanisms to predict pairs with specific therapeutic effects. It serves as a demonstration by applying the model to predict and validate the efficacy of blood-activating herb pairs. MethodsThe training dataset for herb pair prediction was constructed by systematically collecting commonly used herb pairs along with their characteristic data, including Qi, flavor, meridian tropism, and target genes. Integrating traditional characteristics of herb with modern bioinformatics, we developed an efficacy-oriented herb pair compatibility prediction model (HC-GCN) using graph convolutional networks (GCN). This model leverages machine learning to capture the complex relationships in herb pair compatibility, weighted by efficacy features. The performance of the HC-GCN model was evaluated using accuracy (ACC), recall, precision, F1 score (F1), and area under the ROC curve (AUC). Its predictive effectiveness was then compared to five other machine learning models: eXtreme Gradient Boosting (XGBoost), logistic regression (LR), Naive Bayes, K-nearest neighbor (KNN), and support vector machine (SVM). ResultsUsing herb pairs with blood-activating effects as a demonstration, a prediction model was constructed based on a foundational dataset of 46 blood-activating herb pairs, incorporating their Qi, flavor, meridian tropism, and target gene characteristics. The HC-GCN model outperforms other commonly used machine learning models in key performance metrics, including ACC, recall, precision, F1 score, and AUC. Through the predictive analysis of the HC-GCN model, 60 herb pairs with blood-activating effects were successfully identified. Among of these potential herb pairs, 44 include at least one herb with blood-activating effects. ConclusionIn this study, we established an efficacy-oriented compatibility prediction model for herb pairs based on GCN by integrating the unique characteristics of traditional herbs with modern pharmacological mechanisms. This model demonstrated high predictive performance, offering a novel approach for the intelligent screening and optimization of traditional Chinese medicine prescriptions, as well as their clinical applications.

BACKGROUND:Socket-shield technique can effectively maintain labial soft and hard tissues,but the incidence of postoperative complications such as exposure and displacement of root shield is relatively high.It is speculated that the root shield may be exposed and displaced due to excessive load after long-term function of dental implants. OBJECTIVE:Through three-dimensional finite element analysis,we aim to study the influence of varying root shield thicknesses on the stress distribution,equivalent stress peaks,and displacement in the root shield,periodontal ligaments,implant,and surrounding alveolar bone under normal occlusal loading.We also attempt to analyze the correlation between the thickness of the root shield and occurrence of mechanical events such as root shield exposure,displacement,and fracture. METHODS:Cone-beam CT data of a patient who met the indication standard of socket-shield technique for maxillary central incisor were retrieved from database.Reverse engineering techniques were used to build models of the maxillary bone and root shield,while forward engineering was used to create models for the implant components based on their parameters.Models depicting various root shield thicknesses(0.5,1.0,1.5,and 2.0 mm)were created using Solidworks 2022 software.ANSYS Workbench 2021 software was then used to simulate and analyze the effects of varying root shield thicknesses on stress distribution,equivalent stress peaks,and displacement of the root shields,periodontal ligaments,implants,and surrounding alveolar bone under normal occlusion. RESULTS AND CONCLUSION:(1)In all root shield models,the stress was concentrated on the palatal cervical side,both sides of the edges and the lower edge of the labial side.As the thickness of the root shield increased,the equivalent stress peak and displacement showed a decreasing trend.The 0.5 mm thickness model produced a stress concentration of 176.20 MPa,which exceeded the yield strength(150 MPa)of tooth tissue.(2)The periodontal ligament stress in each group was concentrated in the neck margin and upper region.With the increase of root shield thickness,the equivalent stress peak and displacement of periodontal ligament showed a decreasing trend.(3)Implant stress in all models was concentrated in the neck of the implant and the joint of the implant-repair abutment,and the labial side was more concentrated than the palatal side.With the increase of root shield thickness,the equivalent stress peak of the implant in the model showed an increasing trend.(4)In each group of models,stress of cortical bone concentrated around the neck of the implant and the periphery of the root shield,and the labial side was more concentrated than the palatal side.With the increase of the thickness of the root shield,the equivalent stress peak around the root shield decreased;the peak value of the equivalent stress of the bone around the neck of the implant showed an increasing trend.In the model,the stress of cancellous bone was mainly concentrated around the neck of the lip of the implant,the top of the thread,the root tip and the lower margin of the root shield,and the labial side was more concentrated than the palatal side.With the increase of the thickness of the root shield,the peak value of the equivalent stress of the bone around the root shield in the model showed a decreasing trend.The minimum principal stress of cortical bone in each group of models was concentrated around the neck of the implant,exhibiting a fan-shaped distribution.As the thickness of the root shield increased,the minimum principal stress of cortical bone showed an increasing trend.(5)These results indicate that different thicknesses of the root shield have different biomechanical effects.The root shield with a thickness of 0.5 mm is easy to fracture.For patients with sufficient bone width,the root shield with a thickness of 2.0 mm is an option to reduce the risk of complications such as root shield exposure,fracture,and displacement.Meanwhile,it should be taken into account to protect the periodontal ligament in the preparation process,and rounding treatments ought to be carried out on both sides and the lower edge of the root shield.

Objective To investigate the level of pertussis antibody in 344 healthy population in Hebei Province in 2023, and to understand the infection status and estimate the potential infection of pertussis. Methods A total of 344 healthy people of all ages from 7 cities (counties) in Hebei Province in 2023 were stratified by random sampling method. The demographic characteristics, vaccination history and pertussis history of the subjects were collected. Serum IgG antibody against pertussis toxin (PT-IgG) were determined by enzyme-linked immunosorbent assay (ELISA). Results The geometric mean concentration (GMC) of PT-IgG in 344 healthy people was 5.28 IU/mL, and the antibody positive rate (PT-IgG concentration ≥ 40 IU/mL) was 6.10% (21/344). There was no significant difference in proportion of antibody levels and antibody concentration ≥40 IU/mL between males and females. The top three regions with the highest antibody positive rate were Xinhe County in Xingtai (20.00%), Lianchi District in Baoding (11.43%), and Shijiazhuang (9.37%). There was a significant difference in pertussis antibody levels among different regions (P=0.007), but no significant difference in pertussis antibody concentration ≥40 IU/mL among different regions (P=0.100). The GMC of antibody was the highest in the 1~<3 years old group (11.45 IU/mL), followed by the <1 year old group (8.15 IU/mL). There was a significant difference in the pertussis antibody levels among different age groups (P=0.001). The proportion of antibody concentration ≥40 IU/mL was the highest in the 1~<3 years old group (20.83%), followed by the <1 year old group (12.77%). There was a significant difference in the proportion of antibody concentration ≥40 IU/mL among different age groups (P=0.028). And 303 (88.08%) cases of the 344 healthy people had a history of DTaP , 4.62%, 46.86% and 48.52% of healthy people had completed 1-2 , 3 and 4 doses of DTaP, respectively. Among the healthy people who had completed 1-2 doses of DTaP, there was no significant difference in the level of pertussis antibody among different age groups (P=0.47). Among the healthy people who had completed 3 doses of basic immunization and 4 doses of complete immunization, there was a significant difference in the level of pertussis antibody among different age groups (P=0.04, P=0.01). There was no significant difference in the proportion of PT-IgG concentration ≥40 IU/mL among different age groups and different immunization doses (P=0.72). Conclusion The overall antibody level and proportion of PT-IgG concentration ≥40 IU/mL in the healthy population of Hebei Province in 2023 were both low, indicating the inadequacy of the protective effect of the current immunization program for children, although vaccinated people could still infect with pertussis disease, we need to further monitoring and optimization of immune strategies indicating.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.
