Abstract
OBJECTIVE The study aimed at the silence effect of MAT1 gene and proteins in Ishikawa cell of human endometrial carcinoma cell line through RNAi mediated by siRNA and also discussed the effect of MTA1 gene silence on the invasion and metastasis of endometrial carcinoma. MATERIALS AND METHODS According to the principle of designing siRNA sequence, siRNA aiming at MTA1 gene (MTA1-siRNA) and siRNA used for negative control (Control-siRNA) were designed and synthesized and Ishikawa cell was transfected by transfection reagents. RT-PCR method as well as western blot was used, respectively, to detect the MTA1 mRNA and protein expression of stably transfected cells. Transwell method and scarification experiment were adopted to detect the invasion and metastasis of Ishikawa cells. RESULTS The expression results of MTA1 on the levels of mRNA and protein showed that the expression level in transfected MTA1-siRNA group was obviously lower than that in non-transfected group and transfected control-siRNA group (p <0.05), while there was no significant difference between non-transfected group and transfected control-siRNA group (p > 0.05). Effective interference on the expression of MTA1 gene remarkably lowered the invasion and metastasis of endometrial carcinoma Ishikawa cells. CONCLUSION RNAi aiming at MTA1 can effectively inhibit the expression of MTA1 in endometrial carcinoma Ishikawa cells and the effective silence of MTA1 can weaken the invasion and metastasis of Ishikawa cells, which provides a new strategy for gene therapy of endometrial carcinoma and an experimental basis for inhibiting the invasion and metastasis of endometrial carcinoma.

Abstract
PURPOSE Locally advanced rectal cancer (LARC) patients achieving ypT3 status following neoadjuvant chemoradiation are considered to have poor response with minimal downstaging. However, residual cancer cell amounts vary in the subserosa/perirectal fat. Tumor regression grading (TRG) is an evaluation method based on the proportion of fibrosis and residual cancer cells. The aim of this study is to assess the influence of TRG in ypT3 rectal cancer patients who received neoadjuvant chemoradiation. METHODS We retrospectively reviewed 325 LARC patients who received neoadjuvant chemoradiation and surgery. TRG scores were recorded by two independent pathologists. Among these patients, 143 were staged as ypT3. We analyzed TRG and other clinicopathological factors and their relationship with survival outcome including overall survival (OS) and disease-free survival (DFS). RESULTS Among 143 ypT3 patients, 44 (30.8 %) were TRG1, 84 (58.7 %) were TRG2 and 15 (10.5 %) were TRG3. Seventy-nine (55.3 %) of these patients had metastatic lymph nodes. In univariate analysis, TRG was not associated with DFS (TRG2 vs TRG1, P = 0.852; TRG3 vs TRG1, P = 0.593) or OS (TRG2 vs TRG1, P = 0.977; TRG3 vs TRG1, P = 0.665). Palliative surgery (HR 3.845; 95 % CI 1.670-8.857; P = 0.002) and metastatic lymph nodes after surgery (HR 5.894; 95 % CI 1.142-3.48; P = 0.015) were significantly associated with decreased DFS, while palliative surgery was the only factor associated with worse OS (HR 6.011; 95 % CI 2.150-16.810; P = 0.001). Palliative surgery (HR 3.923; 95 % CI 1.696-9.073; P = 0.001) and metastatic lymph nodes (HR 2.011; 95 % CI 1.152-3.512; P = 0.014) also showed prognostic significance for DFS in multivariate analysis. CONCLUSIONS Residual cancer cells evaluated by TRG score after neoadjuvant chemoradiation do not influence survival outcome in ypT3 rectal cancer patients. However, lymph node status is a significant prognostic factor in ypT3 patients.

Abstract
AIMS The aim of this study was to identify new small molecules that can inhibit Streptococcus mutans biofilms by in vitro and in vivo model. METHODS AND RESULTS We evaluated the effect of a small molecule 2-amino-imidazole/triazole conjugate (2-AI/T) on the formation of Strep. mutans biofilms by culturing in 96-well plates. Toxicity was assessed through cell culture and intragastrically administering to mice. The anti-biofilm and anti-caries effects were investigated in vivo. The inhibitive mechanism was detected by isobaric tag for relative and absolute quantification (itraq) and RT-QPCR. In vitro and in vivo study revealed that 2-AI/T significantly inhibited biofilm formation of Strep. mutans and is more so than inhibiting planktonic cells without toxicity. The ribosome and histidine metabolism pathways of Strep. mutans were significantly regulated by this compound. CONCLUSIONS These results suggest that the 2-AI/T conjugate is a potent inhibitor that can be potentially developed into a new drug to treat and prevent dental caries. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study to use small molecule from marine natural products, to protect from dental caries in vivo. It has potential broad range application in clinical caries prevention, or as a bioactive ingredient for food applications.

Abstract
The INT0116 trial established the role of adjuvant chemoradiation (CRT) in the multidisciplinary approach to the management of locally advanced gastric cancer. However, whether adjuvant CRT is indispensable for patients undergoing D2 dissection remains undefined. The adjuvant chemoradiation therapy in stomach cancer (ARTIST) trial, which was designed to compare adjuvant chemotherapy to CRT, failed to demonstrate differences in disease-free and overall survival in the whole study group; however, subgroup analysis indicated that patients with lymph node metastasis may benefit from additional radiation. A follow-up ARTIST II trial is currently under way. The efficacy of adjuvant CRT remains controversial because of variation among studies in the inclusion criteria and treatment delivery methods; however, the identification of patients who would benefit from CRT is critical. Advanced radiotherapy techniques such as intensity-modulated radiotherapy protect normal tissues via motion management and decreased radiation-induced toxicity and contribute to plan optimization. Further studies integrating clinical and molecular factors as well as neoadjuvant CRT are warranted.

Abstract
PURPOSE The purpose of this study was to perform a quantitative review of previous case control studies examining the association between AT1R A1166C polymorphism and pregnancy-induced hypertension (PIH). MATERIALS AND METHODS Odds ratio (OR) and 95% confidence intervals (CI) were used as measures of effect sizes. Overall effect sizes were derived using a random-effects model or fixed-effects model when appreciated, and stratified by ethnicity. Funnel plots and Egger's regression asymmetry tests were utilized for publication bias detection. RESULTS A total of ten articles (including 920 PIH cases and 1408 controls) were included in this meta-analysis. The overall effect sizes (OR = 2.14, 95% CI: 1.54-2.98, p < 0.00001) of additive model indicated PIH patients had a significant higher frequency of allele C. Meanwhile, the OR of the dominant model was 2.22 (95% CI: 1.51-3.26,p < 0.00001) which signified that PIH patients also had a significant higher frequency of AC+CC genotypes. The subgroup analyses were in line with the overall outcomes except the Caucasians PIH patients had a non-significant CA+CC genotypes (OR = 1.37, 95% CI: 0.95-1.98, p > 0.05). The Egger's test of additive model (p = 0.451) and dominant model (p = 0.623) revealed no statistical significance for publication bias. CONCLUSION The meta-analysis suggested that the AT1R Al166C polymorphism was significantly associated with the PIH, especially in Asian subjects.

Abstract
Recent research has verified that mesenchymal stromal/stem cells (MSCs) derived from bone marrow or adipose tissues can migrate toward a variety of tumors. In this study, we explored whether human gingival-derived MSCs (G-MSCs) can migrate toward tongue squamous cell carcinoma (TSCC) and evaluated the antitumor effect of engineered G-MSCs in expressing and delivering the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). An in vitro cell migration assay with Transwell plates showed that human G-MSCs can migrate toward TSCC cell lines (Tca8113 and Cal27). Then, human G-MSCs, as a type of cell-based vehicle, were transduced with full-length TRAIL and enhanced green fluorescent protein reporter genes by the lentivirus (LV) system (G-MSCs with full-length TRAIL; G-MSCFLT). Tca8113 and Cal27 were co-cultured with G-MSCFLT, respectively, to evaluate the function of G-MSCFLT on tumor cells in vitro. This resulted in G-MSCFLT's inducing a great number of tumor cell necrosis and apoptosis. Meanwhile, in vivo antitumor assays were performed by administering G-MSCFLT to nude mice locally and systematically (mixed injection with tumor cells and tail vein injection). This showed that G-MSCFLT can reduce or even inhibit TSCC growth regardless of the method of administration, especially when the mixed injection of tumor cells and G-MSCFLT was at a ratio of 1:1, which showed no tumor formation. Furthermore, this verified that G-MSCFLT migrated toward TSCC in quantity. These data emphasize the effectiveness of G-MSCs as a vehicle for cell-based gene therapy and the antitumor activity of TRAIL-expressing G-MSCs.

Abstract
We report the case of a patient who suffered iatrogenic vertebral artery injury (VAI) during a cervical spine posterior fixation procedure. The patient suffered massive bleeding and hemorrhagic shock at the time of screws placement in C1 lateral mass and C2 pedicle. The postoperative MRI and CT angiography showed a pseudoaneurysm 7.0 cm in diameter in the cervical spine. The iatrogenic VAI during posterior screw fixation is extremely rare. But, it can cause catastrophic consequences. We discuss the causes for the iatrogenic VAI and review the preventative measures and suitable management to avoid iatrogenic complications.

Abstract
This study sought to identify and characterize the function of genes as diagnostic markers for Epstein-Barr virus (EBV)-related nasopharyngeal cancer (NPC). The gene expression profile of GSE13597 was downloaded from the Gene Expression Omnibus database, which included 28 EBV-related NPC gene expression profile data sets, 25 disease samples, and 3 control samples. Data were pre-processed, and differentially expressed genes were screened using the R language. The co-expression coefficient was calculated to construct a co-expression network using Cytoscape. ClusterONE was used to perform module analysis to find enriched gene families. The BiCAT software was used to perform a two-way clustering analysis of differentially expressed gene expression profiles based on the co-expression networks and to verify the enriched gene families, followed by functional enrichment analysis of these gene families. The MCM gene family was found to be enriched in EBV-related NPC. This gene family is essential for eukaryotic DNA replication. Functional analysis of differentially expressed genes in the co-expression network revealed that the enriched biological processes and pathways were mainly involved in the cell cycle. EBV-related NPC is likely associated mainly with the process of cell reproduction, providing a strong basis for the prevention, diagnosis, and treatment of EBV-related NPC and a direction for targeted chemotherapy.

Abstract
Abstract
Background: Apatinib, one specific tyrosine kinase inhibitor that targets the VEGF receptor 2 was assessed in patients with advanced breast cancer. This substudy was to explore potential predictive and prognostic factors for apatinib-treated breast cancer.
Method: 80 patients were enrolled and received a starting dose of apatinib 750 or 500 mg/d in 4-week cycles. Efficacy was assessed according to RECIST 1.1 criteria, toxicity was graded based on the CTC adverse events version 4.0. The analyzed factors included patient-related factors, such as age; tumor-related factors, such as circulating biomarkers determined by multiplex cytokine assay and phosphorylated VEGFR2 by immunostaining; and treatment-related factors, such as adverse events. Cox Proportional Hazard model and Logistic test were performed as multivariate analysis to define the independent prognostic factors.
Result: Median PFS was 3.84 months, OS 10.64 months, with 17.5% of objective response rate.

The most frequent adverse events were hypertension (66.3% for all grades, 17.5% for grade 3/4), hand-foot skin reaction (HFSR, 62.5% for all grades, 20% for grade 3/4), and proteinuria (61.3% for all grades, 7.5% for grade 3/4). According to univariate analysis, longer PFS was correlated with hypertension (p = 0.011), HFSR (p = 0.018), post-menopause (p = 0.021), less previous chemotherapy (p = 0.021), higher drug trough concentration (p = 0.025), and higher baseline serum sVEGFR2 (p = 0.031). Median PFS was 6.60 and 2.00 m in patients with higher and lower p-VEGFR2 expressions (p = 0.001). According to multivariate regression analysis, hypertension (p = 0.038; HR, 0.583, 95% CI 0.351 - 0.969) and p-VEGFR2 expression level (p = 0.013; HR, 0.404, 95% CI 0.198 - 0.826) were independent predictive factors of PFS.

Abstract
This review addressed the adverse effects of the frequently-used recreational drug, ketamine through using mice and monkey models. Our laboratory has documented initially that ketamine can induce the formation of hyperphosphorlated tau (hypertau), which is a hallmark of Alzheimer's disease (AD), in the cerebral cortex of both mice and monkeys as well as apoptosis in neurons in these species. Besides the cerebral cortex, other centers in the central nervous system (CNS) and peripheral nervous system (PNS) are also influenced by ketamine. Cerebellum was found to be down-regulated in both mice and humans after long-term of ketamine administration and it was caused by the apoptosis of Purkinje cells. Deleterious effects in other organs reported in long-term ketamine users include of kidney dysfunction leading to proteinuria, fibrosis of the urinary bladder and reduction in size of the urinary bladder leading to frequent urination, increase of liver fibrosis and cardiac problems such as premature ventricular beats. Moreover, ketamine is usually co-administrated with other chemicals such as caffeine or alcohol. It has been reported increased harmful effects when ketamine was used in combination with the above substances. Mechanisms of damages of ketamine might be due to 1) up-regulation of NMDA receptors leading to overestimation of glutamatergic system or 2) the metabolite of ketamine which was a hydroquinone exerted toxicity.

Abstract
Close homologue of L1 (CHL1) is a transmembrane cell adhesion molecule that is critical for brain development and for the maintenance of neural circuits in adults. Recent studies revealed that CHL1 has diverse roles and is involved in the regulation of recovery after spinal cord injury. CHL1 expression was downregulated in the cerebral cortex, hypothalamus, and brain stem after the induction of acute hypoxia (AH). In the current study, we sought to address the role of CHL1 in regulating homeostasis responses to hypoxia using CHL1-knockout (CHL1−/−) mice. We found that, compared with wild-type littermates, CHL1−/− mice showed a dramatically lower mortality rate and an augmented ventilatory response after they were subjected to AH. Immunofluorescence staining revealed that CHL1 was expressed in the carotid body (CB), the key oxygen sensor in rodents, and CHL1 expression level in the CB as assayed by western blot was decreased after hypoxic exposure. The number of glomus cells and the expression of tyrosine hydroxylase (a marker for glomus cells) in the CB of CHL1−/− mice appeared to be increased compared with CHL1+/+ mice. In addition, in the ex vivo CB preparation, hypoxia induced a significantly greater afferent nerve discharge in CHL1−/− mice compared with CHL1+/+ mice. Furthermore, the arterial blood pressure and plasma catecholamine levels of CHL1−/− mice were also significantly higher than those of CHL1+/+ mice. Our findings first demonstrate that CHL1 is a novel intrinsic factor that is involved in CB function and in the ventilatory response to AH.
