Objective Titanium ions were implanted into Bio-HPP materials using plasma immersion ion implantation(PIII)technology,and the biocompatibility against human gingival fibroblasts(HGFs)and antimicrobial activity against porphyromonas gingivalis(P.g)to the materials were preliminarily evaluated.Methods The cell experiments and antibacterial experiments in vitro were conducted,and the specimens were randomly divided into the modified group and the control group,and the modified specimens were placed in an ion implantation device and implanted with titanium ions by PIII technology.The morphology of the nanostructures on the surface of the materials was observed by scanning electron microscopy.The cytocompatibility of Bio-HPP materials was evaluated by proliferation detection,immunofluorescence staining and cell cycle distribution detection of HGFs.The antibacterial activity of the materials was evaluated by the detection of antibacterial rate of P.g and the expression analysis of pathogenic gene,and the antibacterial mechanism was preliminarily analyzed.Results The surface of Bio-HPP in the control group was relatively flat,and the modified group formed nanopores with diameters of 100 to 300 nm,with smaller nanoparticles distributed in the nanostructures.The cell proliferation rates of HGFs after cultured for 3,5 and 7 days in the modified group were higher than those in the control group(P<0.05).After 4 hours of incubation,the cells spread well on the surface of the both groups,and the cytoskeleton extended further outward,while the spreading area on the surface of the control group was slightly smaller than that of the modified group.After 24 hours of incubation,the cells on the surface of materials in the both groups showed elongated spindle or shuttle shape,with good growth.There was no significant difference in the proportions of cells at stages G1 and G2 between the control group and the modified group(P>0.05).The proportion of cells at stage S in the modified group was higher than that in the control group(P<0.05).After 24 hours of incubation,the number of colonies in the modified group was significantly reduced compared with the control group;the antibacterial rate of the modified group was significantly higher than that of the control group(P<0.05).The relative expression of pathogenic genes fimA on the surface in the modified group was significantly lower than that in the control group(P<0.05).Conclusion Bio-HPP materials modified by titanium plasma implantation promotes the adhesion and proliferation of HGFs,which was conducive to the adhesion of soft tissues around the gingiva,with good antibacterial activity.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Objective To determine the pathogenicity of a novel mutation(c.109_111del)in DKC1 gene of an adult patient,and to analyze the clinical phenotype,immunophenotype and telomere length,so as to provide clues for early clinical identification and diagnosis.Methods The clinical data and peripheral blood samples of the patient were collected for genetic testing and family analysis.The lymphocyte subsets of the patient were detected by Flow cytometry,and the telomere length of the patient and healthy controls were detected by Flow-FISH.Results The main clinical manifestations of the patient were mucocutaneous triad,bone marrow failure and infection.The telomere length of lymphocytes in the patient was significantly shorter than that of healthy controls of the same age,and the absolute value and percentage of lymphocyte subsets were abnormal.Conclusion The clinical manifestations of DC patients are diverse.Flow-FISH detection of telomere length is helpful for early diagnosis of DC patients.

Recent studies have revealed a significant association between Porphyromonas gingivalis(P.gingivalis)infection and poor prognosis in esophageal squamous cell carcinoma(ESCC).Although cer-tain circular RNAs(circRNA)have been shown to suppress ESCC tumorigenesis and progression,their regulatory mechanisms in P.gingivalis infection-associated ESCC remain elusive.In this study,RT-qPCR analysis demonstrated that P.gingivalis infection downregulated hsa_circ_0057552 expression in ESCC cells and tissues in a time-and dose-dependent manner.Actinomycin D assays further confirmed that P.gingivalis infection reduced the RNA stability of hsa_circ_0057552 in ESCC cells(P＜0.05).Functional assays in vitro and a subcutaneous tumor xenograft model in vivo revealed that hsa_circ_0057552 overexpression significantly inhibited ESCC cell proliferation,migration,invasion,and tumor growth(P＜0.05).Additionally,PCR array screening combined with RT-qPCR and Western blotting in-dicated that P.gingivalis infection markedly upregulated human antigen R(HuR)expression at both RNA and protein levels(P＜0.05).Mechanistic investigations demonstrated that HuR knockdown signifi-cantly increased hsa_circ_0057552 expression(P＜0.01),whereas hsa_circ_0057552 overexpression had no regulatory effect on HuR.Finally,si-HuR treatment reversed the inhibitory effect of P.gingivalis on hsa_circ_0057552 transcription.This study demonstrated that P.gingivalis may promote the progression of ESCC through a novel mechanism involving the regulation of HuR/hsa_circ_0057552,thereby identif-ying a novel therapeutic target and molecular marker for P.gingivalis-associated ESCC.

Objective To explore the effect of personality characteristics on the facial esthetic satisfaction of edentulous patients,in order to provide reference for improving esthetic satisfaction after complete denture restoration.Methods Twenty-two edentulous sub-jects were randomly selected.Before complete denture treatment,the emotional stability of patients was assessed by Eysenck personality questionnaire N scale score(EPQ-N).Before and three months after treatment,patients completed the orofacial esthetic questionnaire,and 3D stereophotogrammetry was performed to evaluate the changes in facial appearance.In addition,multiple linear regression model was established by using N scale score,changes in facial appearance and facial esthetic satisfaction score.Results After complete denture treatment,the difference in the ratio of the middle and lower parts of the face between patients and the normal group was re-duced by(3.85±2.63)%,and the difference of the nasolabial angle between patients and the normal group was reduced by(6.66°±5.39°).The multiple linear regression model showed that N scale score and changes of the differencein the facial proportion between edentulous subjects and normal population were influencing factors of patients'esthetic satisfaction on the facial appearance,and the N scale score and changes of the difference inthe nasolabial anglebetween patients and normal population were influencing factors of the patients'aesthetic satisfaction on the facial profile.Moreover,the effect of two independent variables(N scale score and facial soft tissue change)on the aesthetic satisfaction of facial appearance and facial profile was statistically significant(P＜0.001).Furthermore,when the N score increased,the patients'aesthetic satisfaction on the facial appearance and facial profile decreased(B＜0).Conclusion Personality can affect the aesthetic satisfaction of edentulous patients.Consequently,we should take reasonable measures for patients with different personality in the process of complete denture restoration,so as to achieve the goal of improving patients'aesthetic satisfaction.
