ABSTRACT
ObjectiveTo investigate the expression level of Golgi transport 1A （GOLT1A） in thyroid carcinoma and its effects on the proliferation， migration， invasion， and epithelial-mesenchymal transition （EMT） of thyroid carcinoma cells. MethodsThe expression of GOLT1A in thyroid carcinoma was analyzed online by tumor immune estimation resource （TIMER）， the University of Alabama at Birmingham cancer data analysis portal （UALCAN）， gene expression profiling interactive analysis 2 （GEPIA2）. The expression level of GOLT1A in thyroid carcinoma cells was detected by real-time fluorescence quantitative polymerase chain reaction （RTFQ-PCR） and western blot. Cell counting kit-8 （CCK-8） assay， colony formation assay， and transwell assay were used to detect the effects of GOLT1A expression on the proliferation， migration， and invasion of thyroid carcinoma cells. Western blot assay was used to detect the effect of GOLT1A on the expression of EMT-related genes including E-cadherin， vimentin， and N-cadherin. ResultsThe online analysis of GEPIA2， TIMER， and UALCAN showed that the expression of GOLT1A was higher in thyroid carcinoma than in normal tissues， and the expression of GOLT1A in thyroid carcinoma cells was significantly higher than in normal control cells. Knockdown of GOLT1A inhibited TPC1 cell proliferation， migration， and invasion. The expression of E-cadherin increased and the expressions of N-cadherin and vimentin decreased in GOLT1A knockdown TPC1 cells. Overexpression of GOLT1A promoted BCPAP cell proliferation， migration， and invasion. The expression of E-cadherin decreased and the expressions of N-cadherin and vimentin increased in GOLT1A overexpression BCPAP cells. ConclusionGOLT1A is highly expressed in thyroid carcinoma and can promote the proliferation， migration， and invasion of thyroid carcinoma cells.
ABSTRACT
Objective:To investigate the effects of metformin on the survival of patients with advanced non-small cell lung cancer (NSCLC).Methods:PubMed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang and other databases were searched from the beginning of database construction to February 2020, relevant literatures were screened and included, and the characteristics of the literatures were extracted. RevMan 5.3 software was used to analyze progression-free survival (PFS), overall survival (OS), hazard ratio(HR) and 95% CI; the heterogeneity and publication bias were also evaluated. Results:A total of 11 studies were enrolled, and metformin did not improve PFS in patients with advanced NSCLC ( HR = 0.80, 95% CI 0.58-1.09, P = 0.15). The subgroup analysis results of different treatment strategies showed that metformin combined with tyrosine kinase inhibitor (TKI) ( HR = 0.71, 95% CI 0.32-1.57, P = 0.39), chemoradiotherapy ( HR = 0.97, 95% CI 0.59-1.61, P = 0.92), and immune checkpoint inhibitor (ICI) ( HR = 0.64, 95% CI 0.35-1.16, P = 0.14) did not improve the PFS. Metformin improved OS in patients with advanced NSCLC ( HR = 0.84, 95% CI 0.75-0.93, P = 0.001). Metformin combined with TKI ( HR = 0.68, 95% CI 0.38- 1.22, P = 0.19) and ICI ( HR =0.80, 95% CI 0.39-1.63, P = 0.54) did not improve OS of patients, while metformin combined with chemoradiotherapy could improve OS ( HR = 0.85, 95% CI 0.78-0.93, P < 0.01). No evidence of publication bias was shown in the funnel plot analysis. Conclusions:Metformin can prolong OS time in patients with advanced NSCLC, especially in patients undergoing metformin combined with radiotherapy and chemotherapy, or concurrent chemoradiotherapy.
ABSTRACT
Objective The clinical effect of Allitride as disinfectant in infective root canal of deciduous teeth was studied. Methods 40 teeth were put into the cotton thist with Allitride juice in root canals,sealed by zno for a week. FC CP were used in the contrast groups with consist of 38 teeth. Results The effect of 24 teeth in the Allitride group were excellent, 13 teeth were benign, The efficiency was 92 percent. In CP group, 8 teeth were excellent, 5 teeth were benign, The efficiency was 72 percent. 11 excellent effect and 7 benign effect were in FC group. The efficiency was 90 percent. There are significant difference between Allitrade group and GP group(P0.05). The Allitride effect have not significant relation with age, tooth position.Conclusions Allitride is a good disinfectant adapt to infective root canal of deciduous teeth.
