Abstract
OBJECTIVE Fatty liver may induce various complications including chronic hepatitis or liver cirrhosis, and is frequently occurred in obesity individuals. Advanced glycosylation end products (AGEs) were known to play a critical role in multiple liver diseases. This study, therefore, aimed to study the effect of AGEs on obesity, related liver cirrhosis and inflammation, on an obesity fatty liver rat model. MATERIALS AND METHODS A total of 60 Sprague Dawley (SD) rats were randomly divided into control, model and AGEs inhibitor groups (n=20 each). AGEs level, body weight and liver function were examined in each animal, followed by hematoxylin-eosin (HE) staining to detect the pathological change of liver. Further Real-time PCR and enzyme-linked immunosorbent assay (ELISA) were employed to detect inflammatory cytokine levels including tumor necrosis factor (TNF)-α and interleukin (IL)-6. RESULTS AGEs level was significantly elevated in obesity fatty liver model rats, which also had higher total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) levels, along with deteriorated liver function and higher TNF-α and IL-6 levels. The application of AGEs inhibitor aminoguanidine significantly improved liver functions and lower TNF-α or IL-6 levels when compared to the model group (p<0.05 in all cases). CONCLUSIONS Obesity fatty liver can promote AGEs level, further causing pathological changes and increased secretion of inflammatory cytokines. The inhibition of AGEs can improve the metabolism of fatty acids, decrease inflammatory cytokines and benefit the treatment of obesity fatty liver.

Abstract
OBJECTIVE Asian melanoma patients, predominantly comprised of acral and mucosal subtypes, might not benefit from immunotherapy and targeted therapy as much as Caucasian patients. Novel treatment strategies are demanded after conventional treatment failure. This was a prospective, single-arm, and single-center dose escalation study to investigate the safety and preliminary efficacy of apatinib combined with temozolomide in heavily treated advanced melanoma patients. METHODS Patients were sequentially admitted to four dose-escalating groups of apatinib and temozolomide (three cases in each group) using a traditional 3 + 3 dose escalation design method. RESULTS Twelve patients were enrolled between December 2016 and August 2017. Most patients with an acral or mucosal primary origin progressed after immunotherapy or targeted therapy. Dose escalation had been completed without dose-limiting toxicity. Common adverse events included hypertension, hand-foot syndrome, proteinuria, neutropenia, nausea, and fatigue. All adverse events were grade 1 or 2, while the maximum tolerated dose was not reached. Up to January 2018, 1 patient achieved partial response, 9 experienced stable disease, and 2 exhibited progressive disease. The objective response rate and disease control rate were 8.3% and 83%, respectively. CONCLUSIONS In conclusion, apatinib combined with temozolomide was well tolerated and has demonstrated efficacy in advanced melanoma patients.

Abstract
A major challenge in systems biology is to infer the parameters of regulatory networks that operate in a noisy environment, such as in a single cell. In a stochastic regime it is hard to distinguish noise from the real signal and to infer the noise contribution to the dynamical behavior. When the genetic network displays oscillatory dynamics, it is even harder to infer the parameters that produce the oscillations. To address this issue we introduce a new estimation method built on a combination of stochastic simulations, mass action kinetics and ensemble network simulations in which we match the average periodogram and phase of the model to that of the data. The method is relatively fast (compared to Metropolis-Hastings Monte Carlo Methods), easy to parallelize, applicable to large oscillatory networks and large (~2000 cells) single cell expression data sets, and it quantifies the noise impact on the observed dynamics. Standard errors of estimated rate coefficients are typically two orders of magnitude smaller than the mean from single cell experiments with on the order of ~1000 cells. We also provide a method to assess the goodness of fit of the stochastic network using the Hilbert phase of single cells. An analysis of phase departures from the null model with no communication between cells is consistent with a hypothesis of Stochastic Resonance describing single cell oscillators. Stochastic Resonance provides a physical mechanism whereby intracellular noise plays a positive role in establishing oscillatory behavior, but may require model parameters, such as rate coefficients, that differ substantially from those extracted at the macroscopic level from measurements on populations of millions of communicating, synchronized cells.

Abstract
BACKGROUND The hypothesis that mucosal melanomas from different anatomic sites would have different prognostic features and survival outcome was tested in a multifactorial analysis. METHODS Complete clinical and pathological information from 706 mucosal melanoma patients from different anatomical sites was compared for overall survival (OS) and prognostic factors. RESULTS Mucosal melanomas arising from different anatomical sites did not have any significant differences in OS in a multivariate analysis (p = 0.721). Among all 706 stage I-IV mucosal melanoma patients, depth of tumor invasion (p < 0.001), number of lymph node metastases (p < 0.001), and sites of distant metastases (p < 0.001) were independent prognostic factors for OS; among 543 stage I-III patients, depth of tumor invasion (p < 0.001) and number of lymph node metastases (p < 0.001) were independent prognostic factors for OS; and among 547 stage IV patients, depth of tumor invasion (p = 0.009), number of lymph node metastases (p < 0.001), and combined distant metastases and elevation of serum lactate dehydrogenase (LDH; p < 0.001) were independent prognostic factors for OS. The presence of c-KIT or BRAF mutations was not predictive of survival. CONCLUSIONS This is the first large-scale study comparing outcomes of mucosal melanomas from different anatomic sites in a multifactorial analysis. There were no significant survival differences among mucosal melanomas arising at different sites when matched for staging and prognostic and molecular factors, thus rejecting our hypothesis. We concluded that prognostic characteristics of mucosal melanomas can be staged as a single histological group, regardless of the anatomic site of the primary tumor.

Abstract
Ultra-translucent zirconias are drawing immense attention due to their fascinating esthetic appearance. However, the high translucency came at the expense of diminishing strength along with the reduced ability of transformation toughening due to the increased cubic zirconia content. We aim to address these issues by infiltrating glass on the surface of an ultra-translucent zirconia (5Y-PSZ). Glasses of different shades can be used and the resulting graded glass/zirconia layer is expected to improve the material's flexural strength without compromising its esthetics. We also aim to elucidate how clinically relevant surface treatments-namely, air abrasion, glazing, or polishing-affect the fracture resistance of these zirconias with a high cubic content. All surface treatments were performed on bar-shaped (2 × 3 × 25 mm3) and plate-shaped (12 × 12 × 1 mm3) specimens, which were then subjected to a 4-point bending test and translucency measurements, respectively. 5Y-PSZ proved to be significantly more translucent than 3Y-TZP but also much weaker. Our hypothesis was accepted, as the strength of the glass-infiltrated ultra-translucent 5Y-PSZ (582 ± 20 MPa) is over 70% higher than its uninfiltrated counterpart (324 ± 57 MPa). Its strength is also over 25% higher than the highly polished 5Y-PSZ (467 ± 38 MPa). In addition, the translucency of 5Y-PSZ (translucency parameter [ TP] = 34, contrast ratio [ CR] = 0.31) is not affected by glass infiltration ( TP = 34, CR = 0.32) when the residual surface glass is removed by gentle polishing using 6- and then 3-µm diamond grits. Finally, both air abrasion and the presence of a glaze layer on the tensile surface decreased flexural strength significantly, being 274 ± 55 and 211 ± 21 MPa, respectively. With a combined high strength and translucency, the newly developed glass-infiltrated 5Y-PSZ may be considered a suitable material for next-generation, damage-resistant, and esthetic dental restorations.

Abstract
Extracellular ATP is a widespread cell-to-cell signaling molecule in the brain, where it functions as a neuromodulator by activating glia and neurons. Although ATP exerts multiple effects on synaptic plasticity and neuro-glia interactions, as well as in mood disorders, the source and regulation of ATP release remain to be elaborated. Here, we define Calhm2 as an ATP-releasing channel protein based on in vitro and in vivo models. Conventional knockout and conditional astrocyte knockout of Calhm2 both lead to significantly reduced ATP concentrations, loss of hippocampal spine number, neural dysfunction and depression-like behaviors in mice, which can be significantly rescued by ATP replenishment. Our findings identify Calhm2 as a critical ATP-releasing channel that modulates neural activity and as a potential risk factor of depression.

Abstract
Objective The objective of this study was to establish a stable model of orthotopic liver transplantation with external biliary drainage in rats, to provide the possibility for dynamic detection of bile characteristics after transplantation. Methods Ninety-eight Sprague Dawley rats were divided randomly into a control group (n = 30) and an external drainage group (n = 68). Biliary extra-drainage group rats were established as follows: an epidural catheter was implanted into the common bile duct and an appropriate hose was connected from the outside. A stoma was made into the high jejunum, and a hose was implanted. Then the 2 hoses were induced to connect with each other in the subcutis of the right lateral abdominal wall. Results The operative success rate and 1-week and 2-week survival rates of the extra-drainage group were 94.1% (64/68), 88.2% (60/68), and 79.4% (54/68), respectively. Meanwhile, in the control group, the operative success rate and 1-week and 2-week survival rates were 93.3% (28/30), 90% (27/30), and 83.3% (25/30), respectively. There were no significant differences at any time between the 2 groups (p > 0.05). Conclusions The biliary extra-drainage model in rat orthotopic liver transplantation provides a novel, simple, and reliable method for dynamic collection of bile. The operation success rate was satisfactory. This model was successful and could be applied in various experimental studies.

Abstract
OBJECTIVES To investigate the effects of black cohosh and estrogen on the temperature in ovariectomized rats, the core body temperature (CBT) and tail-skin temperature (TST) were simultaneously monitored and the relationship between these two temperatures was explored. METHODS Twenty-four female Sprague-Dawley rats aged 8 weeks were randomly divided into four groups: sham-operated (SHAM), ovariectomized (OVX), OVX treated with estradiol valerate (OVX + E), and OVX treated with isopropanolic black cohosh extract (OVX + ICR). Rats were sham-operated or ovariectomized and were implanted with telemetry transmitters with dual thermistor probes. Two weeks after surgery, the animals were treated with drugs for 4 weeks. During the last week of the treatments, the dynamic temperature profiles of the CBT and TST were collected. RESULTS The average CBT and TST, TST fluctuation frequency, and the average amplitude fluctuation were significantly higher in OVX than in SHAM rats. In addition, dramatic fluctuations of TST in OVX rats occurred at the time points of the day when the CBTs were lower in OVX rats than in SHAM rats. Treatment of OVX rats with estradiol valerate or isopropanolic black cohosh extract markedly decreased the average CBT and TST, TST fluctuation frequency, and the average amplitude fluctuation. Moreover, CBT was found to be significantly higher, while TST was lower in OVX + E than in OVX + ICR rats. CONCLUSIONS Both black cohosh and estradiol treatments ameliorated the abnormal thermoregulation in OVX rats. In particular, black cohosh reduced CBT better than estradiol and estradiol reduced TST better than black cohosh.

Abstract
High-dose interferon alfa-2b (IFN-α-2b) improves the survival of patients with high-risk melanoma. We aimed to identify baseline peripheral blood biomarkers to predict the outcome of acral melanoma patients treated with IFN-α-2b. Pretreatment baseline parameters and clinical data were assessed in 226 patients with acral melanoma. Relapse-free survival (RFS) and overall survival (OS) were assessed using the Kaplan-Meier method, and multivariate Cox regression analyses were applied after adjusting for stage, lactate dehydrogenase (LDH), and ulceration. Univariate analysis showed that neutrophil-to-lymphocyte ratio ≥2.35, platelet-to-lymphocyte ratio ≥129, systemic immune-inflammation index (SII) ≥615 × 109/l, and elevated LDH were significantly associated with poor RFS and OS. The SII is calculated as follows: platelet count × neutrophil count/lymphocyte count. On multivariate analysis, the SII was associated with RFS [hazard ratio (HR)=1.661, 95% confidence interval (CI): 1.066-2.586, P=.025] and OS (HR=2.071, 95% CI: 1.204-3.564, P=.009). Additionally, we developed a novel circulating T-cell immune index (CTII) calculated as follows: cytotoxic T lymphocytes/(CD4+ regulatory T cells × CD8+ regulatory T cells). On univariate analysis, the CTII was associated with OS (HR=1.73, 95% CI: 1.01-2.94, P=.044). The SII and CTII might serve as prognostic indicators in acral melanoma patients treated with IFN-α-2b. The indexes are easily obtainable via routine tests in clinical practice.

Abstract
Head and neck cancer is one of the most prevalent cancers around the world. Head and neck squamous cell carcinoma (HNSCC) accounts for nearly 90% of head and neck cancer. In recent years, significant advances have been made in immunotherapy for HNSCC. Although some clinical trials targeting immune checkpoints have shown success, the molecular mechanism for regulation of programmed death 1 (PD-1) and its ligand (PD-L1) is partially understood. In an effort to explore the effect of activation of signal transducers and activators of transcriptions (STAT3) on PD-1/PD-L1, the expression and correlation between phosphorylation of STAT3 and PD-1/PD-L1 were determined with immunostaining of human and mouse HNSCC tissue sections. PD-1/PD-L1 overexpression was found to be significantly associated with p-STAT3 in human and mouse HNSCC. Targeting STAT3 by a small molecule effectively inhibited the expression of PD-L1 in the CAL27 cell line. Furthermore, we found that blockade of STAT3 signaling downregulated PD-1/PD-L1 in a Tgfbr1/Pten 2cKO HNSCC mouse model. These findings suggest that STAT3 signaling plays an important role in PD-1/PD-L1 regulation and the antitumor immune response of HNSCC.

Abstract
WHAT IS KNOWN AND OBJECTIVE Research has indicated that some Chinese herb injections (CHIs) might be beneficial in combination with chemotherapy, including remedies that might be used as effective chemosensitizers and radiosensitizers, or as palliative therapy. Here, we carried out a network meta-analysis to assess the clinical efficacy and safety of CHIs combined with oxaliplatin, 5-fluorouracil and leucovorin (FOLFOX) for advanced colorectal cancer (CRC). METHODS PubMed, EMBASE.com, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Biomedical Literature Database (CBM), Wanfang Database and Chinese Journal Full-text Database were searched from inception to 31 December 2014, to identify relevant randomized controlled trails (RCTs). The risk of bias in included RCTs was evaluated according to the Cochrane Handbook version 5.1.0. Standard pairwise meta-analysis and Bayesian network meta-analysis were performed to compare the efficacy and safety of different CHIs combined with FOLFOX. Data were analysed using STATA 12.0 and WinBUGS1.4 software. RESULTS AND DISCUSSION We identified 63 eligible studies (with 4837 patients in total), involving 9 CHIs. Pairwise meta-analysis showed that compared with FOLFOX alone, combinations with Aidi injection and compound matrine injection could significantly improve the overall response rate and quality of life and reduce the incidence of nausea and vomiting (III-IV), diarrhoea (III-IV), thrombocytopenia (III-IV), leukopenia (III-IV) and peripheral neurotoxicity (III-IV). According to results of indirect comparison, there were no statistically significant differences for most of comparison groups. Aidi+FOLFOX, shenqifuzheng+FOLFOX and compound matrine+FOLFOX had the greatest probability of being the best treatment in clinical efficacy and safety, considering the small sample size. WHAT IS NEW AND CONCLUSIONS Most of the included studies were of low quality, and there was a scarcity of eligible trials and numbers of participants. Based on currently limited evidence, aidi, shenqifuzheng and compound matrine were superior to other CHIs in patients receiving FOLFOX chemotherapy for advanced CRC. More studies are required to confirm the efficacy of CHIs in combination with FOLFOX for advanced CRC.

Abstract
Sulforaphane (SFN) is a kind of isothiocyanate derived from broccoli and other cruciferous vegetables. Because of its roles of antioxidant, anti-inflammatory, and anti-tumor through multiple targets and various mechanisms, SFN has drawn broad attention of the researchers. One of the most important target of SFN is nuclear factor erythroid 2 related factor 2 (Nrf2), wildly known for its ability to regulate the expression of a series of cytoprotective enzymes with antioxidative, prosurvival, and detoxification effects. Multiple researches have shown that SFN protects against central nervous system diseases through Nrf2pathway. In this article, we list SFN contents in common cruciferous vegetables, and summarize recent advances in the protective effects of SFN against acute brain injuries and neurodegenerative diseases through activating Nrf2 signaling pathway.

Abstract
OBJECTIVE Paroxysmal supraventricular tachycardia (PSVT) patient has higher prevalence ratio of atrial fibrillation (AF), while AF recurrence remains a high ratio after radiofrequency ablation (RFCA). This study explored AF prevalence and atrial vulnerability in PSVT patients after RFCA, using ROC curve to analyze atrial effective refractory period dispersion (dERP) on postoperative AF in the prediction of PSVT. PATIENTS AND METHODS The PSVT patients were enrolled and divided into three groups and received RFCA treatment between January 2010 and December 2014. Group A, AF was induced by programmed electrical stimulation (PES) under isopropyl epinephrine (ISO) perfusion; group B, AF was induced by PES or PES under ISO perfusion; group C, no AF was generated by PES or PES under ISO perfusion. Ultrasonic cardiogram was applied to detect intra, inter, atrial electromechanical delay and dERP. ROC curve was adopted to analyze the prediction effect of dERP on postoperative AF recurrence. RESULTS dERP, group B > A > C; inter and intra: group B > A (p<0.05). Logistic regression analysis showed that age, gender, sympathetic nerve stimulation, and left/right atrial diameter were independent risk factors of postoperative AF in PSVT patients (p<0.05). Of note, dERP cut-off value at 75.5 msec can effectively predict AF recurrence in PSVT patients after RFCA (p<0.05). CONCLUSIONS Atrial vulnerability index dERP could be applied to evaluate AF recurrence in PSVT patients after RFCA.
