Objective To explore the clinical efficacy and safety of mouth three oxide inorganic polymer under a microscope to repair the pulp cavity perforation.Methods 120 patients with medullary cavity perforation, caries origin were selected as the research subjects,they were randomly divided into oral microscope inorganic oxide polymer repair the pulp cavity perforation of the experimental group and the resin inlay repair the pulp cavity perfora-tion of the control group,each group had 60 cases.The postoperative occlusion pain,swollen gums and loose,fistula formation,the incidence of chewing function not completed and X -ray curtate alveolar bone density decrease the shadow changes were compared between the two groups.Results The incidence rates of bite pain,swollen gums, loosening of the observation group were 5.00%,3.33%,6.67%,which of the control group were 11.60%,13.33%, 18.33%,the differences between two groups were significant (χ2 =5.49,P <0.05;χ2 =4.76,P <0.05;χ2 =4.23, P <0.05).The fistula formation,chewing function not completed,X -ray curtate alveolar bone density to reduce shadow expand of the observation group were 3.33%,5.00%,5.00%,which of the control group were 10.00%, 30.00%,40.00%,the differences between the two groups were significant (χ2 =5.34,P <0.05;χ2 =4.12,P <0.05;χ2 =4.56,P <0.05).Conclusion The clinical curative effect of oral three oxide inorganic polymer under a microscope to repair the pulp cavity perforation is outstanding,compared with the resin inlay repair the pulp cavity perforation has many advantages,it can be used as a kind of ideal method used in the clinical work.

Objective To evaluate the expression of FUNDC1 and its clinical significance in non-small cell lung cancer. Methods We used TCGA database to analyze the difference of mitochondrial receptors (DRP1, BNIP3, FUNDC1, NIX, RHEB, LC3, OPA1 and MFN1) expression between normal and NSCLC tissues, as well as its effect on the prognosis of NSCLC patients. Immunohistochemistry was used to detect FUNDC1 expression. The correlations between FUNDC1 expression and clinicopathological characteristics, prognosis were evaluated by SPSS 22.0 statistical software. Results FUNDC1 expression was increased in NSCLC tissues, compared with normal tissues. FUNDC1 expression was related to the degree of differentiation and lymph node metastasis, but not to gender, age, pathological type, distant metastasis or TNM classification. The Cox regression analysis showed that FUNDC1 protein expression, lymph node metastasis, differentiation degree were independent prognostic factors of NSCLC. Increased FUNDC1 expression was related to decreased OS and PFS (P < 0.01). Conclusion The up-regulation of FUNDC1 expression can affect the prognosis of patients with NSCLC. It may be a new potential target for treating with NSCLC.
