The prevalence of periodontitis in China is as high as 74.2%, making it the leading cause of tooth loss in adults and severely impacting both oral and overall health. The treatment of periodontitis and periodontal tissue regeneration are global challenges of significant concern. GE Shaohua' s group at School and Hospital of Stomatology, Shandong University has focused on the key scientific issue of "remodeling the periodontal inflammatory microenvironment and optimizing tissue repair and regeneration". They have elucidated the mechanisms underlying the persistence of periodontitis, developed bioactive materials to enhance stem cell regenerative properties, and constructed a series of guided tissue regeneration barrier membranes to promote periodontal tissue repair, leading to the establishment of a comprehensive technology system for the treatment of periodontitis. Specific achievements and progress include: (1) Elucidating the mechanism by which key periodontal pathogens evade antimicrobial autophagy, leading to inflammatory damage; developing intelligent antimicrobial hydrogels and nanosystems, and creating metal-polyphenol network microsphere capsules to reshape the periodontal inflammatory microenvironment; (2) Explaining the mechanisms by which nanomaterial structures and electroactive interfaces regulate stem cell behavior, developing optimized nanostructures and electroactive biomaterials, thereby effectively enhancing the regenerative repair capabilities of stem cells; (3) Creating a series of biphasic heterogeneous barrier membranes, refining guided tissue regeneration and in situ tissue engineering techniques, stimulating the body' s intrinsic repair potential, and synergistically promoting the structural regeneration and functional reconstruction of periodontal tissues. The research outcomes of the group have innovated the fundamental theories of periodontal tissue regeneration, broken through foreign technological barriers and patent blockades, established a cascade repair strategy for periodontal regeneration, and enhanced China' s core competitiveness in the field of periodontal tissue regeneration.

OBJECTIVES: We propose a segmented backprojection tensor degradation feature encoding (SBP-MAC) model for motion artifact correction in dental cone beam computed tomography (CBCT) to improve the quality of the reconstructed images. METHODS: The proposed motion artifact correction model consists of a generator and a degradation encoder. The segmented limited-angle reconstructed sub-images are stacked into the tensors and used as the model input. A degradation encoder is used to extract spatially varying motion information in the tensor, and the generator's skip connection features are adaptively modulated to guide the model for correcting artifacts caused by different motion waveforms. The artifact consistency loss function was designed to simplify the learning task of the generator. RESULTS: The proposed model could effectively remove motion artifacts and improve the quality of the reconstructed images. For simulated data, the proposed model increased the peak signal-to-noise ratio by 8.28%, increased the structural similarity index measurement by 2.29%, and decreased the root mean square error by 23.84%. For real clinical data, the proposed model achieved the highest expert score of 4.4221 (against a 5-point scale), which was significantly higher than those of all the other comparison methods. CONCLUSIONS The SBP-MAC model can effectively extract spatially varying motion information in the tensors and achieve adaptive artifact correction from the tensor domain to the image domain to improve the quality of reconstructed dental CBCT images.

Objective:To discuss the expression and clinical significance of inositol polyphosphate-4-phosphatase type Ⅱ(INPP4B)gene in hepatocellular carcinoma(HCC)based on The Cancer Genome Atlas(TCGA)database and experimental verification with clinical samples.Methods:Based on data from 424 clinical samples in the TCGA database(including 374 HCC tissues and 50 paracarcinoma tissues),Kaplan-Meier method and Cox regression analysis were used to evaluate the relationship between INPP4B gene and the clinical characteristics and survival prognosis of the HCC patients.The correlations between INPP4B gene and the number of 24 types of immune cells,matrix,immune cell infiltration and tumor purity in tumor tissue,and the expression level of the high-frequency mutant gene tumor protein 53(TP53)in HCC were analyzed.The clinicopathological data and paraffin-embedded tissue sections of 60 HCC patients treated with surgical resection from December 2022 to December 2023 were collected.According to clinical diagnosis,they were divided into poorly differentiated group(HCC-L group),moderately differentiated group(HCC-M group)and well-differentiated group(HCC-H group),with 20 cases in each group;20 patients during the same period who underwent biopsy and were pathologically diagnosed as non-tumor were selected as normal group,and their clinicopathologic data and liver tissue paraffin sections were collected.HE staining was used to observe the pathomorphology of HCC tissue and normal liver tissue of the subjects in various groups;immunohistochemistry method was used to detect the expressions of Ki-67 and INPP4B proteins in the HCC tissue and normal liver tissue of the subjects in various groups.Results:The TCGA database analysis results showed that compared with normal tissue,the expression level of INPP4B mRNA in HCC tissue was significantly increased(P<0.01).Compared with INPP4B low expression group,the overall survival(OS)of the patients in INPP4B high expression group was significantly prolonged(P<0.05).The univariate Cox regression analysis results showed that tumor stage,pathological stage,tumor status and residual tumor had impacts on OS of the HCC patients(P<0.05).The univariate regression analysis results showed that the INPP4B prognostic risk model score ratio was HR=0.781,95％confidence interval(CI):0.552-1.105,P=0.168.The AUC value for the impact of INPP4B on OS of the HCC patients was 0.558,indicating that the INPP4B gene prognostic risk model had certain predictive value in survival prognosis.The INPP4B mRNA expression level was not correlated with TNM stage,stage,patient gender,age,race or body mass index(BMI)(P>0.05).In tumor tissue with high and low INPP4B expression,22 types of immune cells showed statistically significant differences(P<0.05);the INPP4B mRNA expression level was positively correlated with the number of 23 types of immune cells except T helper(Th)17 cells(r>0),among which all Th cells except natural killer(NK)CD56+cells were statistically significant(P<0.01);INPP4B was significantly correlated with matrix(r=0.475),immune cell infiltration(r=0.641)and tumor purity(r=0.599)in tumor tissue(P<0.01).INPP4B was correlated with TP53(r=0.287,P<0.01).The HE staining results showed that clear and complete lobular structure,neatly arranged cells and slight inflammatory cell infiltration were observed in liver tissue of the subjects in normal group;completely destroyed lobular structure,significant hepatocellular steatosis,massive inflammatory cell infiltration,and lesions such as ballooning degeneration and small cell hyperplasia in some cells were observed in HCC tissue of the patients in HCC-L,HCC-M and HCC-H groups,and the lower the HCC differentiation degree,the more severe the tissue destruction;The immunohistochemistry results showed that compared with normal group,the expression levels of Ki-67 protein in HCC tissue of the patients in HCC-L,HCC-M and HCC-H groups were significantly increased(P<0.01),and the lower the differentiation degree of the HCC patients,the higher the Ki-67 positive rate.Brownish-yellow granules evenly distributed in the cells and INPP4B protein was highly expressed in liver tissue of the subjects in normal group;compared with normal group,the expression levels of INPP4B protein in HCC tissue of the patients in HCC-L,HCC-M and HCC-H groups were significantly decreased(P<0.01),and the lower the differentiation degree of the HCC tissue,the lower the INPP4B positive rate.Conclusion:INPP4B is a protective factor for the prognosis of HCC patients;as a new tumor suppressor gene,INPP4B may become a potential target for new drug screening in HCC treatment.

Objective To explore the predictive value of combined serum soluble hemoglobin scavenger receptor 163(sCD163),hypersensitive C-reactive protein(hs-CRP),and procalcitonin(PCT)for stroke-associated pneumonia(SAP).Methods A total of 100 patients with acute ische-mic stroke admitted to the First Hospital of Zhangjiakou from October 2021 to January 2023 were se-lected as the study subjects.According to whether they developed SPA within 7 days of admission,they were divided into SAP group(n=64)and non-SAP group(n=36).Based on pneumonia se-verity index(PSI),patients in the SAP group were further divided into mild SAP group and severe SAP group.Enzyme-linked immunosorbent assay(ELISA)was used to detect the serum levels of sCD163,hs-CRP,and PCT.The clinical data of the patients were collected and compared.Pearson's method was used to analyze the correlation between the PSI score and the serum levels of sCD163,hs-CRP,and PCT in SAP patients.Multivariate Logistic regression analysis was employed to screen for factors influencing the occurrence of SAP.Receiver operating characteristic(ROC)curve analy-sis was used to evaluate the predictive efficacy of serum sCD163,hs-CRP,and PCT for the occur-rence of SAP.Results The proportion of patients with dysphagia and the National Institutes of Health Stroke Scale(NIHSS)score in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the severe SAP group were significantly higher than those in the mild SAP group(P＜0.05).Pearson's correlation analysis showed that the PSI score was positively correlated with the serum levels of sCD163,hs-CRP and PCT in SAP patients(r=0.356,0.413,0.391,P＜0.001).Logistic regression analysis revealed that serum sCD163,hs-CRP,PCT,NIHSS score,and dysphagia were all influencing factors for the occurrence of SAP(P＜0.05).The areas under the curve(AUC)for predicting SAP using serum sCD163,hs-CRP,PCT and their combina-tion were 0.842,0.924,0.866 and 0.973,respectively,with sensitivities of 73.44％,84.37％,67.19％and 90.62％,and specificities of 88.89％,83.33％,97.22％and 94.44％,respectively.The predictive value of the combined detection was superior to that of the individual detection of ser-um sCD163,hs-CRP and PCT(P＜0.05).Conclusion The serum levels of sCD163,hs-CRP,and PCT are elevated in SAP patients,and their changes are closely related to the severity of the disease.The combined detection of these three indicators has a high value in predicting the occur-rence of SAP and may serve as auxiliary markers for predicting early SAP.

OBJECTIVE To investigate the diagnostic efficacy of serum calcitonin(Ctn)in medullary thyroid cancer(MTC),the correlation between preoperative serum Ctn and clinicopathological features,and the risk factors affecting the progression of MTC disease during follow-up.METHODS The clinical data of 50 patients admitted to the Hospital of Integrated Traditional Chinese and Western Medicine of Nanjing University of Chinese Medicine from 2011 to 2022 were systematically reviewed,the ROC curve calculated the diagnostic efficacy of Ctn and CEA levels on MTC,and the risk factors for lymph node metastasis in the central region of MTC were analyzed in univariate and multivariate,and the survival curve without disease progression was drawn to predict risk factors.RESULTS The ROC curve yields the preoperative cut-off value of Ctn was 23.81 pg/ml and the cut-off value of CEA was 3.035 ng/ml for the diagnosis of MTC.The age of disease,tumor diameter,and preoperative serum Ctn and CEA levels in MTC patients were higher than those in non-MTC patients.Ctn≥289.62 pg/ml was an independent risk factor for central lymph node metastasis in MTC.The survival curve showed that invasion of the capsule,central region metastasis,and TNM stage above T2 were risk factors for predicting disease progression(P<0.05).Patients with MTC who have disease progression have higher preoperative Ctn.CONCLUSION Serum Ctn has important clinical value in the differential diagnosis,preoperative evaluation and postoperative follow-up of MTC.
