13% and 22.58%, respectively. The difference was statistically significant (P less then 0.05). The positive expression rate of Bcl-2 protein in gingival carcinoma tissues with different degrees of differentiation was statistically significant (P less then 0.05). In different degrees of differentiation, gingival carcinoma with cervical lymph node metastasis, there was significant difference in the positive expression rate of MIF protein in gingival cancer tissues (P less then 0.05). Conclusions The expression of Bcl-2 and MIF protein is up-regulated in gingival cancer tissues of the elderly, which has certain relationship with the degree of tumor differentiation and cervical lymph node metastasis.Purpose To evaluate the accuracy of implant digital impression，in order to provide guidance in digital implant prosthesis. Methods According to the requirements, 115 patients undergoing implantation were randomly selected. The implantation impression cap was placed and scanned with CBCT after esteosenesis. Oral cavity was scanned to make the 3D digital implantation model. The model data were obtained by scanning the digital resin implantation models. Based on the remaining teeth, the model data and CBCT data were matched in Nobel Clinicion software. Results The implantation impression cap in the patient's CBCT was completely matched and overlapped with the digital model in all of the occlusal, coronal and sagittal planes,which meant that the position, direction and angle of the implantation in the oral cavity were exactly the same as those in the digital model made by oral scanning. Conclusions 3D digital resin model of oral scanning printing is completely accurate and can be popularized and applied in clinic.Purpose To investigate the expression of secreted frizzle-related protein 1 (SFRP1) and macrophage migration inhibitory factor (MIF) in elderly patients with severe periodontitis and its correlation with cognitive function. Methods Thirty-two elderly patients with periodontitis in Qingdao Stomatological Hospital from February 2018 to February 2019 were enrolled, and divided into two groups according to the severity mild group and severe group. All selected subjects received periodontal examination and Montreal cognitive assessment (MoCA).The expression of SFRP1 and MIF in serum was also determined. Then the correlations among SFRP1 and MIF periodontal index and cognitive function was analyzed. The data were processed by SPSS 20.0 software package. Results The probing depth (PD), clinical attachment level (CAL), sulcus bleeding index (SBI) and gingival crevicular fluid (GCF) showed significant difference between the two groups (P less then 0.05). The serum levels of SFRP1 and MIF in the severe group were significantly higher than those in the mild group (P less then 0.05). Serum SFRP1 level was positively correlated with MIF (P less then 0.05). Vorinostat Serum SFRP1 and MIF levels were positively correlated with periodontal index (P less then 0.05). The MoCA score of the severe group was significantly lower than that of the mild group (P less then 0.05). Serum SFRP1 and MIF levels were negatively correlated with MoCA score (P less then 0.05). Conclusions SFRP1 and MIF are highly expressed in serum and gingival tissues of elderly patients with severe periodontitis, and are closely related to the degree of periodontal damage. Meanwhile, patients with periodontitis may have some degree of cognitive dysfunction, and SFRP1 and MIF may affect the periodontal tissue structure through Wnt/β-catenin signal pathway and participate in the occurrence and development of cognitive dysfunction.Purpose To investigate the correlation between salivary stress markers chromogranin A (CgA), cortisol, α-amylase, β-endorphin and clinical parameters of periodontitis, including sulcus bleeding index (SBI), periodontal probing depth (PD) and attachment loss (AL). Methods A total of 105 patients with chronic periodontitis (periodontitis group) and 105 healthy individuals (control group) visiting our hospital from December 2017 to December 2018 were selected. Indicators including CgA, cortisol, α-amylase, β-endorphin levels, SBI, PD, and AL were detected in both groups, and the correlation among them was determined by Pearson's analysis, multivariate logistic regression was used to analyze the risk factors associated with periodontitis using SPSS 22.0 software package. Results The levels of CgA, cortisol, α-amylase and β-endorphin in the periodontitis group were significantly higher than those in the control group (P less then 0.05). SBI, PD and AL in the periodontitis group were significantly higher than those in the control group (P less then 0.05). The levels of CgA, cortisol, α-amylase and β-endorphin in saliva were positively correlated with SBI, PD, and AL (P less then 0.05). CgA, cortisol, α-amylase, and β-endorphin were independent risk factors for periodontitis (P less then 0.05). Conclusions Salivary stress markers CgA, cortisol, α-amylase, and β-endorphin are significantly associated with clinical parameters of periodontitis, suggesting that they can reflect the progression of periodontitis, thus providing an effective reference for diagnosis and efficacy monitoring of periodontitis.Purpose To observe the effect of dynamic nutrition support on postoperative energy metabolism, immune function and stress response in patients with oral and maxillofacial tumors. Methods Fifty-six patients with oral and maxillofacial tumor surgery were randomly divided into experimental group and control group (28 in each group). Patients in the experimental group received dynamic enteral and parenteral nutrition support according to the stress period after surgery, ω-3 fish oil fat milk injection and glutamine were added in the nutrition support program. Patients in the control group were given routine postoperative enteral and parenteral camp support. Energy metabolism, immune function and stress indexes were detected 1 day before surgery, 2 days after surgery and 7 days after surgery, respectively. SPSS 19.0 software package was used to analyze the data. Results Energy metabolism indexes in the experimental group were higher than the control group on day 2 after PA surgery and day 7 after ALB and PA surgery, while energy metabolism indexes in the experimental group were lower than the control group on day 2 and day 7 after FPG and TG surgery with significant difference(P less then 0.
