METHODS The cancer tissues and adjacent normal tissues of 46 patients with OSCC who underwent tumor resection in the Affiliated Stomatological Hospital of Anhui Medical University from June 2017 to June 2018 were included in the study. Immunohistochemical staining was used to observe the expression of Smad4 in tissues, Western blot was used to determine the expression of Smad4 in tumor cells. The effects of disulfiram on TGF-β1-induced cell EMT migration, invasion, morphology and expression of p38, JNK and ERK were analyzed. SPSS 20.0 software package was used to analyze the data. RESULTS The positive expression rate of Smad4 in cancer tissues was significantly lower than that in adjacent normal tissues (P 0.05). The survival rate of human tongue cancer SCC-25 and CAL-27 cells was significantly lower than that of the control group at disulfiram concentrations ≥30 μmol/L(P<0.05). After treatment with TGF-β1, the morphology of SCC-25 and CAL-27 cells changed from epithelial to mesenchymal. E-cadherin expression was significantly reduced, Vimentin and Snail expression were significantly increased, and migration and invasion were enhanced (P<0.05). After disulfiram + TGF-β1 treatment, as the concentration of disulfiram increased, the morphological changes of SCC-25 and CAL-27 cells gradually decreased, the expression of E-cadherin protein gradually increased, the expression of Vimentin and Snail protein gradually decreased, and migration ability gradually weakened (P<0.05). After 5 minutes of TGF-β1 stimulation, p-ERK levels in SCC-25 and CAL-27 cells gradually increased, reached a maximum at 15 minutes, and then gradually decreased (P<0.05). After 20 μmol/L disulfiram + TGF-β1 treatment, p-ERK levels in SCC-25 and CAL-27 cells gradually decreased with the increase of the treatment time(P<0.05). CONCLUSIONS Disulfiram can inhibit EMT of Smad4 mutant and Smad4 non-mutated OSCC cells by blocking ERK phosphorylation in the MAPK signaling pathway.","PeriodicalId":436266,"journal":{"name":"Chinese Journal of Oral Implantology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131105373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS: Two hundred preschool children who were treated with pit and fissure closure from January 2014 to September 2014 were selected as subjects. According to random number table method, 100 cases were divided into the combined group and the control group. Children in the control group were treated with pit and fissure sealant for prevention of caries, while children in the combined group were treated with sodium fluoride tooth protector combined with pit and fissure sealant for caries prevention. The incidence of dental caries, proximal caries, mean DMFT, and expulsion rate of the sealants were compared between the two groups at 1 year and 2 years. Data analysis was performed using SPSS 16.0 software package for data analysis. RESULTS: At 1 year of follow-up, there was no significant difference in the incidence of dental caries, proximal caries, and mean DMFT between the two groups (P>0.05). The incidence of caries and mean DMFT in the combined group were significantly lower than those in the control group at 2 years of follow-up (P 0.05). The retension rate of the pit and fissure sealant in the combined group was significantly higher than that in the control group (P 0.05). CONCLUSIONS: Sodium fluoride tooth protector combined with pit and fissure sealing has better anti-caries effect than the use of pit and fissure sealant alone in preschool children.","PeriodicalId":436266,"journal":{"name":"Chinese Journal of Oral Implantology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123651225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, with the widespread use of these drugs, reports on the difficulty of wound healing (DWH) increase remarkably. However, the mechanism is still unclear. The soft tissue injury was suspected to cause DWH in many recent reports. This experiment was designed to explore the influence of zoledronic acid on fibroblast, and investigate the possible mechanisms leading to DWH. METHODS: NIH 3T3 fibroblasts were routinely cultured in vitro. The influence of zoledronic acid on apoptosis, proliferation and migration of fibroblast were tested with flow cytometry, MTT and cell migration assay, respectively. The results of each experimental group were compared with the control group using SPSS 17.0 software package. RESULTS: At a concentration of 5-50 μmol/L, zoledronic acid could dose-dependently inhibit the activity of fibroblast proliferation and migration, and up-regulate apoptosis with significant difference (P<0.05). CONCLUSIONS: Zoledronic acid can up-regulate cell apoptosis, inhibit proliferation and migration of fibroblast, suggesting that soft tissue impairment might contribute to the occurrence of DWH.","PeriodicalId":436266,"journal":{"name":"Chinese Journal of Oral Implantology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122395555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS At the time of admission, the general information and past medical history of 177 patients with advanced OSCC were collected in detail. All patients underwent radical resection. After surgery, radiotherapy and chemotherapy with hydroxycampothecin (HCPT) and pingyangmycin (PYM) were performed according to the patient's condition. All patients were followed up for 5 years after surgery, and the survival rate during that period and the risk factors for prognosis were analyzed. The data were analyzed by SPSS 20.0 software package. RESULTS During the follow-up period, 2 patients died due to other causes, 4 were excluded due to lost to follow-up, 42 of the remaining 111 patients died, 69 survived, the total survival rate was 62.16%. The survival status of patients with advanced OSCC with different age, T stage and M stage had no significant difference (P>0.05), while significant difference was found among patients with different gender, tissue differentiation degree, N stage and chemotherapy (P 0.05). The survival curves of gender, N stage and HCPT in combination of PYM chemotherapy had certain predictive value on the survival of patients with advanced OSCC. CONCLUSIONS Gender, N stage and HCPT in combination of PYM chemotherapy are independent risk factors for the survival of patients with advanced OSCC, and their survival curves can be used as a survival prediction model.","PeriodicalId":436266,"journal":{"name":"Chinese Journal of Oral Implantology","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116977778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
