Objective:To investigate the effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in modulat-ing the effects of oral squamous cell carcinoma (OSCC) invasion. Methods:Real-time polymerase chain reaction was employed to de-tect the expression of MALAT1 in samples of OSCC post-radical resection, normal oral mucosa samples, and oral squamous cell lines. MALAT1-siRNA was transfected into TSCCa human tongue squamous cell carcinoma cell lines. Cell proliferation was determined by methyl-thiazolyl-tetrazolium reduction assay. Cell migration and invasive ability were evaluated by scratch test and transwell assay. The expression of proteins that regulated invasion and apoptosis were examined using Western blot assay. Immunofluorescence assay was used to detect changes in epithelial-mesenchymal transition (EMT)-associated proteins in the cells. Tumor-bearing nude mouse models were established by subcutaneous implantation of TSCCa cells. Immunohistochemistry was used to detect up-regulation of proliferating cell nuclear antigen (PCNA) and matrix metalloproteinase-2/9 (MMP-2/9). Results:MALAT1 expression was significantly higher in OSCC than in normal tissues (P<0.05). MALAT1 expression was inhibited by transfecting MALAT1-siRNA. After MALAT1 expres-sion was down-regulated in TSCCa cells, proliferation was inhibited and invasion was attenuated, showing significant differences com-pared with the cells transfected with scrambled siRNA and control cells (P<0.05). Expression of N-cadherin and MMP-2/9 were down-regulated in the cells after MALAT1 was knocked down. Tumor growth was significantly slower in the MALAT1-siRNA group than in the control groups. IHC indicated that PCNA and MMP-2/9 expression of tumor tissues were significantly inhibited in MALAT1-siR-NA group. Conclusion:MALAT1 is over-expressed in human OSCC. MALAT1 reduction can inhibit the proliferation and invasion of OSCC cells. Furthermore, MALAT1 may promote OSCC invasion and metastasis by modulating EMT.

OBJECTIVES:
One of the underlying mechanisms of aging is chronic inflammation, which has been closely associated with daily diet. Phenotypic age (PhenoAge) has been used as an index to track the aging process before diseases show clinical symptoms. The present study aimed to explore the association between the dietary inflammatory index (DII) and PhenoAge.
METHODS:
In total, 9,275 adults aged 20 years old and over in the National Health and Nutrition Examination Survey were involved in this study. Dietary patterns were classified as pro-inflammatory or anti-inflammatory according to the DII. PhenoAge was regarded as a continuous variable, and linear regression was used to explore its association with dietary inflammation. Stratified analyses by sex, age, race, physical exercise, smoking status, drinking status, and body mass index were used to test the sensitivity of these associations.
RESULTS:
The median value of PhenoAge was 38.60 years and 39.76 years for the participants with anti-inflammatory and pro-inflammatory diets, respectively. A pro-inflammatory diet was positively associated with PhenoAge (β=0.73; 95% confidence interval, 0.31 to 1.14), compared with participants who had an anti-inflammatory diet. There was an interaction between dietary inflammation and age for PhenoAge (pinteraction<0.001). The strength of the association between a pro-inflammatory diet and PhenoAge was stronger as age increased.
CONCLUSIONS
A pro-inflammatory diet was associated with a higher PhenoAge, and the association was strongest in the elderly. We recommended reducing dietary inflammation to delay phenotypic aging, especially for the elderly.

Objective:To explore the effects of HT-2 toxin on expressions of silent information regulator of transcription 1 (SIRT1) and autophagy and apoptosis pathway related proteins in cultured chondrocytes in vitro. Methods:The third-generation chondrocytes of SD neonatal rats aged 1 to 2 days were cultured in vitro and identified by toluidine blue staining and type Ⅱ collagen immunofluorescence staining. CCK-8 method was used to detect the proliferation of chondrocytes. According to the cell survival rate, 2, 4 and 8 ng/ml HT-2 toxin were selected for subsequent experiments, and the exposure time was 48 h. At the same time, a negative control group and a solvent (absolute ethanol) control group were set up. Western blotting was used to detect the expressions of SIRT1 and autophagy and apoptosis pathway related proteins [microtubule-associated protein 1 light chain 3 (LC3)-Ⅱ, LC3-Ⅰ, p62, Beclin1, Caspase-3, B-cell lymphoma-2 (Bcl-2) and Bcl-2-Associated X protein (Bax)] in each group. Results:After staining, the cells were identified as chondrocytes with high purity. The expression levels of SIRT1 protein in 2, 4, 8 ng/ml HT-2 toxin groups (0.69 ± 0.18, 0.46 ± 0.13, 0.35 ± 0.19) were significantly lower than that in negative control group (1.00 ± 0.39, P < 0.05). In 2, 4 and 8 ng/ml HT-2 toxin groups, the ratios of autophagy pathway related proteins LC3-Ⅱ and LC3-Ⅰ expressions (LC3-Ⅱ/LC3-Ⅰ, 1.47 ± 0.15, 1.37 ± 0.13, 1.81 ± 0.34) were higher than that in negative control group (1.00 ± 0.21, P < 0.05), and the expression levels of p62 protein in 4, 8 ng/ml HT-2 toxin groups (0.70 ± 0.04, 0.57 ± 0.01) were lower than that in negative control group (1.00 ± 0.15, P < 0.05). In 2, 4, 8 ng/ml HT-2 toxin groups, the expression levels of apoptosis pathway related protein Bcl-2 (0.61 ± 0.06, 0.54 ± 0.16, 0.47 ± 0.06) were significantly lower than that in negative control group (1.00 ± 0.14, P < 0.05), and the ratio of Bax to Bcl-2 protein expressions in 8 ng/ml HT-2 toxin group (Bax/Bcl-2, 3.27 ± 0.18) was higher than that in negative control group (1.00 ± 0.27, P < 0.05). The expression level of SIRT1 protein was significantly negatively correlated with the expression level of autophagy pathway related protein LC3-Ⅱ ( r = - 0.819, P < 0.01), and was significantly positively correlated with the expression level of p62 protein( r = 0.772, P < 0.01), but not with the expression level of Beclin1 protein ( r = 0.399 , P > 0.05); there was no correlation between SIRT1 protein expression and apoptosis pathway related protein Caspase-3 and Bax expressions ( r = - 0.297、- 0.284, P > 0.05), but there was a significant positive correlation with Bcl-2 protein expression ( r = 0.755, P < 0.01). Conclusion:HT-2 toxin may increase the expression of autophagy pathway related protein LC3-Ⅱ/LC3-Ⅰ, decrease the expression of p62 protein, and increase the apoptosis pathway related protein Bax/Bcl-2 by inhibiting the expression of SIRT1 protein in chondrocytes, resulting in abnormal autophagy and apoptosis, and finally leads to the injury of chondrocytes.

Hemangioma is the most common vascular benign tumor in infants and young children, 60% of which occur in the oral maxillo-facial region. One characteristic of oral and maxillofacial hemangioma is spontaneous regression, which generally does not require treatment; however, a few hemangiomas can produce complications including ulceration, functional disorders and disfigurement, which require active treatments. Currently, the treatment of oral and maxillofacial hemangioma include drug treatment, laser treatment and surgical treatment. The drugs used to treat hemangioma mainly include beta blockers, glucocorticoids, alpha-interferon, imiquimod and antitumor drugs. Drug therapy is suitable for multiple, rapidly proliferating hemangiomas and hemangiomas that affect vital organ function or endanger life. Laser therapy can be applied to the early treatment of rapidly growing hemangiomas at exposed sites. Surgical treatment is suitable for proliferative hemangioma with serious complications, the reconstruction of any external deformity and the repair of a scar after an ulcer. Combined therapy and the development of new technologies provide new directions for the treatment of hemangioma but the efficacy remains to be proven by large sample prospective studies. Clinicians should appropriately evaluate the patients with hemangioma and develop individualized treatment programs for patients with treatment indications. This article reviews the efficacy, mechanism, clinical application and adverse reactions of different treatment methods and provides references for clinical treatment.
