Abstract
BACKGROUND The Fas cell surface death receptor (FAS) and Fas ligand (FASL) can participate in the apoptosis of immune cells and target cells infected with a virus through the FAS-FASL signalling pathway. The decoy receptor 3 (DCR3) can competitively inhibit the binding of FAS to FASL. Our aim is to investigate the effect of single nucleotide polymorphisms (SNPs) in FAS, FASL and DCR3 on hepatitis C virus (HCV) infection. METHODS Four SNPs (rs763110 in FASL, rs1324551 and rs2234767 in FAS and rs2257440 in DCR3) were genotyped in 1495 controls free of HCV, 522 individuals with spontaneous HCV clearance and 732 patients with hepatitis C virus infection. The RegulomeDB database and RNAfold web servers were used to explore potential biological functions of SNPs. RESULTS FASL rs763110 was associated with susceptibility to HCV infection, and not to CHC. The odds ratio (95% confidence interval) of HCV infection in high-risk populations carrying FASL rs763110-TT was 1.82 (1.36-2.51, P < 0.001) compared to that of CC genotypes and 1.93 (1.43-2.60, P < 0.001) higher than that of CC + CT genotypes. Based on computer simulation, FASL rs763110-T may affect the transcription of mRNA by affecting the binding of a transcription factor, leading to structural changes in mRNA. CONCLUSION The genetic variant in FASL is linked with HCV infection, but not to spontaneous HCV clearance.

Abstract
Abstract Objective To analyze the differences among electrical damage, burns and abrasions in pig skin using Fourier transform infrared microspectroscopy (FTIR-MSP) combined with machine learning algorithm, to construct three kinds of skin injury determination models and select characteristic markers of electric injuries, in order to provide a new method for skin electric mark identification. Methods Models of electrical damage, burns and abrasions in pig skin were established. Morphological changes of different injuries were examined using traditional HE staining. The FTIR-MSP was used to detect the epidermal cell spectrum. Principal component method and partial least squares method were used to analyze the injury classification. Linear discriminant and support vector machine were used to construct the classification model, and factor loading was used to select the characteristic markers. Results Compared with the control group, the epidermal cells of the electrical damage group, burn group and abrasion group showed polarization, which was more obvious in the electrical damage group and burn group. Different types of damage was distinguished by principal component and partial least squares method. Linear discriminant and support vector machine models could effectively diagnose different damages. The absorption peaks at 2 923 cm-1, 2 854 cm-1, 1 623 cm-1, and 1 535 cm-1 showed significant differences in different injury groups. The peak intensity of electrical injury's 2 923 cm-1 absorption peak was the highest. Conclusion FTIR-MSP combined with machine learning algorithm provides a new technique to diagnose skin electrical damage and identification electrocution.

Abstract
Graphene/hBN heterostructures are promising active materials for devices in the THz domain, such as emitters and photodetectors based on interband transitions. Their performance requires long carrier lifetimes. However, carrier recombination processes in graphene possess sub-picosecond characteristic times for large non-equilibrium carrier densities at high energy. An additional channel has been recently demonstrated in graphene/hBN heterostructures by emission of hBN hyperbolic phonon polaritons (HPhP) with picosecond decay time. Here, we report on carrier lifetimes in graphene/hBN Zener-Klein transistors of ~30 ps for photoexcited carriers at low density and energy, using mid-infrared photoconductivity measurements. We further demonstrate the switching of carrier lifetime from ~30 ps (attributed to interband Auger) down to a few picoseconds upon ignition of HPhP relaxation at finite bias and/or with infrared excitation power. Our study opens interesting perspectives to exploit graphene/hBN heterostructures for THz lasing and highly sensitive THz photodetection as well as for phonon polariton optics. Long carrier lifetimes are beneficial for graphene-based optoelectronics, but carrier recombination processes in graphene possess sub-picosecond characteristic times. Here, the authors report carrier lifetimes ~30 ps at low energy in graphene/hBN Zener-Klein transistors, attributed to interband Auger processes.

Abstract
Objective: To understand the etiology of hepatopathy of unknown etiology in patients undergoing liver biopsy. Methods: Demographic data and pathological examination reports of patients with hepatopathy of unknown etiology who underwent liver biopsy examination at outpatient and inpatient of the Second Hospital of Nanjing between January 2017 and June 2018 were retrospectively collected. All liver histopathological sections combined with clinical and pathological features based on liver biopsy examinations were diagnosed by a reputed clinician and a pathologist. Results: A total of 470 cases with hepatopathy of unknown etiology who underwent liver biopsy were enrolled. Of these, 425 cases (90.4%) had a definite diagnosed disease after comprehensive analysis of pathological and clinical data. The diagnosis of hepatopathy of unknown etiology included 11 diseases: 90 cases with autoimmune hepatitis had autoimmune liver disease (19.1%), 38 cases had primary biliary cholangitis (8.1%), 43 cases with overlap syndrome of autoimmune hepatitis had primary biliary cholangitis (9.1%), 118 cases had drug-induced liver injury (25.1%), 75 cases had nonalcoholic fatty liver disease (NAFLD) (16.0%), 12 cases had alcoholic liver disease (2.6 cases) %), 15 cases (3.2%) had vascular liver disease, 7 cases (1.5%) had hereditary metabolic liver disease, 5 cases (1.1%) had other systemic diseases, 16 cases (3.4%) had more than two kinds of liver diseases, and 6 cases (1.3%) had others rare liver diseases. Conclusion: Over 90% cause of the hepatopathy of unknown etiology in the long run can be determined, and the main causes are autoimmune liver disease, drug-induced liver injury, and nonalcoholic fatty liver disease, which needs multidisciplinary cooperation to diagnose, and clinicians need to master the basic and clinical knowledge of liver diseases as well as liver pathology, hepatobiliary imaging, and genetics.

Abstract
Background There are various endoscopic techniques for thyroid carcinoma dissection but few reports regarding the scarless neck technique and central compartment dissection (CCD) via the breast approach, especially for bilateral CCD are available. In this study, we reported 45 cases with scarless neck endoscopic total or near-total thyroidectomy plus CCD via the breast approach. Materials and Methods Forty-five female patients with papillary thyroid carcinoma (PTC) were enrolled in the study, from January 2011 to March 2013. In brief, 5 mm ultrasonic coagulation device (Harmonic Scalpel, HS; Ethicon Endosurgery, USA) was used to perform thyroid vessel management and thyroidectomy. Twenty patients underwent total thyroidectomy and 25 underwent near-total thyroidectomy. CCD was performed in all 45 patients, including 13 with bilateral CCD and 32 with ipsilateral CCD. Results The procedure was successful for all 45 patients. Sixteen patients (35.6%) had lymph node metastases in central compartments. Postoperative transient adverse events included voice changes (9 patients) and hypocalcemia (18 patients), including 7 (21.9%) in the unilateral group and 11 (84.6%) in bilateral group. There was no permanent hypocalcemia or recurrent laryngeal nerve (RLN) palsy. None of the case were converted to open surgical procedure. All patients were satisfied with the cosmetic result of the scarless neck endoscopic thyroidectomy (SET). No evidence of residual or recurrent disease was found during a mean follow-up of 22.84 months (range, 12-34 months). Conclusions Experienced thyroid surgeons performed the scarless neck endoscopic total or near-total thyroidectomy plus unilateral or bilateral CCD via the breast approach for selected PTC patients. The procedure was safe and feasible with excellent cosmetic results.

Abstract
Abstract
Background
Pre-operative echocardiography is performed in selected groups of patients for cardiac risk stratification prior to surgery. Many parameters, including Left Ventricular Ejection Fraction (LVEF), are assessed during echocardiography. While many studies have cited association between low LVEF and poor operative outcomes such as perioperative myocardial infarction or cardiogenic pulmonary edema, LVEF has limitations such as left ventricular (LV) cavity border tracing, geometric assumptions and inter-observer variability. LVEF may also appear normal in the presence of LV hypertrophy and a small LV cavity size. Studies have described the routine use of global longitudinal strain (GLS) as an alternative measure of ventricular function, with GLS having been reported to be a reliable marker in detecting subclinical LV dysfunction. This adds incremental value in predicting myocardial function and in risk stratification. In fact, some studies have documented GLS being a useful preoperative parameter in predicting postoperative LV dysfunction after cardiac valve surgery.
Purpose
The aim of this study is to determine the value of GLS in predicting post-operative outcomes in patients undergoing non-cardiac surgeries.
Methods
This was a retrospective study of all patients who had echocardiography performed for a pre-operative indication from February 2017 to October 2017. These patients were screened for those who had normal LVEF, had undergone subsequent non-cardiac surgery, and had post-operative troponins measured. Medical records were traced for baseline demographics, past medical history and echocardiographic features. GLS evaluation was prospectively performed using TOMTEC-ARENA (TOMTEC Imaging Systems GmbH) by assessors blinded to patient outcomes. Outcomes for major adverse cardiovascular events and mortality up to 1 year post surgery were collected. Post-op myocardial injury was defined as a peak Troponin T value of >30 ng/L or a >20% increment from baseline.
Results
A total of 42 patients were included. 61.9% (n = 26) were male and mean age was 72.3 years. Only 75.6% of patients were fully independent with activities of daily living and mean creatinine was 153.4μmol/L. Mortality at 1 year was 16.7% (n = 7) and 28.6% (n = 12) were deemed to have post-operative myocardial injury. 1-year mortality was associated with a lower GLS (-23.8% vs -19.2%, p = 0.001). However, GLS was not correlated with post-operative myocardial injury or hospital readmissions. In our study population, only a history of past myocardial infarction predicted post-op myocardial injury (58.3% vs 16.7%, p = 0.019).
Conclusion
Our study did not demonstrate the utility of GLS in predicting post-operative events, but this is likely because of the small sample size with low event rates. Nevertheless, GLS values did correlate with 1-year mortality and could be a marker of frailty and an increased mortality risk.

Abstract
Abstract Age estimation is of great significance in the fields of criminal investigation and forensic identification. It can provide the age information of individuals to judicial departments to facilitate the development of judicial work. In recent years, age estimation methods expanded from the morphological level to the molecular biology level. With the rapid development of epigenetics represented by DNA methylation, and the advancement of DNA methylation detection technology together with the detection platform, many age estimation methods based on DNA methylation biomarkers, or using several biological fluids, such as blood, blood stains, saliva, semen stains, etc. are developed. Currently, researches related to age estimation based on DNA methylation are relatively widely carried out. This paper summarizes the researches on age estimation based on DNA methylation, in order to provide references for related studies and forensic applications.

Abstract
The freshwater Chinese mitten crab (Eriocheir sinensis), an indigenous crustacean in China, has been cultured for more than 30 years. It was reported that the bunya-like virus from Eriocheir sinensis (EsBV) was associated with the tremor disease (TD), which causes high mortality and has a serious impact on production. In this study, full-length genome sequences of EsBV were pursued using next generation sequencing; the genome of EsBV was found to be composed of 6.7 kb L, 3.3 kb M, and 0.8 kb S segments, respectively. PCR detection based genomic sequences showed that the positive rate of EsBV reached 40% in crabs from farming ponds. EsBV had the highest similarity with the Wenling crustacean virus 9, an unassigned, negative sense ssRNA virus. EsBV clustered with the Wenling crustacean virus 9 firstly, and then the branch clustered with Peribunyaviridae clade in every phylogenetic tree - based on L, M and S encoded sequences, respectively, indicating that EsBV can be classified in the family Peribunyaviridae, to which the orthobunyaviruses belongs, but not belonging to any known genera in the family Peribunyaviridae. There were unique complimentary terminal sequences for EsBV, with only partial consensus with members from the orthobunyaviruses. We believe that the findings of this research will be vital for future research about EsBV and will also go a long way in illuminating its relationship with TD. Keywords: Eriocheir sinensis; tremor disease; bunyavirus; EsBV; genome sequences.

Abstract
OBJECTIVE Recently, studies have identified that microRNAs (miRNAs) are novel regulators for gene expression in tumor progression including breast cancer. The aim of the study is to investigate the clinical significance and underlying functions between miR-508-3p expression and triple-negative breast cancer (TNBC) development. PATIENTS AND METHODS Quantitative Real-time PCR (QRT-PCR) was performed to determine the expression of miR-508-3p in 54 pairs of TNBC specimens and adjacent non-tumor tissues. The association between miR-508-3p expression and clinicopathological factors was assessed using x2-test. Transwell invasion assays were used to assess cell invasion ability. Luciferase reporter assay, Western blot analyses and qRT-PCR were performed to demonstrate ZEB1 was a direct target of miR-508-3p. RESULTS We demonstrated that miR-508-3p expression was remarkably decreased in TNBC tissues and cells. Lower miR-508-3p expression significantly associated with lymph node metastasis and distant metastasis in TNBC patients (p < 0.05). Ectopic expression of miR-508-3p significantly suppressed cell invasion ability of TNBC. MiR-508-3p overexpression suppressed cell epithelial-mesenchymal transition (EMT) phenomenon of TNBC by upregulating E-cadherin expression, but downregulating Vimentin expression. In addition, we revealed that ZEB1 was a direct target of miR-508-3p in TNBC cells. MiR-508-3p significantly suppressed cell EMT process by regulating ZEB1 expression. CONCLUSIONS We found that miR-508-3p may be a potential therapeutic target of TNBC.

Abstract
BACKGROUND Helicobacter pylori infects almost half of the world population and is listed as a type I carcinoma factor since 1994. Pogostemon cablin (Blanco) Benth. (Labiatae) has been used to treat gastro-intestinal diseases for thousands of years in many east Asian countries, and the key ingredient, patchouli alcohol (PA), has been observed to exert anti-H. pylori and anti-urease activities. PURPOSE We investigated the effect of PA on H. pylori urease and its subsequent influence on macrophage phagosome maturation and function. METHODS In H. pylori experiment, the berthelot method and pH shock assay were adopted to evaluate the effect of PA on extracellular and intracellular H. pylori urease. And then, Q-PCR and Western blot were carried out to analyze the alterations in the expression of urease-related genes and proteins after PA treatment. In the H. pylori and macrophage cell (RAW264.7) co-culture experiment, the effects of PA on H. pylori-induced phagocytosis and intracellular killing of RAW264.7 were investigated using gentamycin protection assay, and the underlying mechanism was explored by immunofluorescence. RESULTS PA at 25 and 50 μM inhibited intracellular H. pylori urease activity but not isolated urease by down-regulating the gene expression levels of ureB, ureE, ureI and nixA and reducing the protein expression level of UreB, thereby inhibiting the acid resistance of H. pylori. PA also recovered the function of macrophage bacterial digestion, and prior treatment with ammonium chloride inhibited the efficacy of PA. CONCLUSION PA suppressed intracellular H. pylori urease function and maturation, which increased macrophage digestion ability.

Abstract
Objective: To investigate the tumor necrosis factor receptor superfamily 1B gene (TNFRSF1B) polymorphism in relation to the outcomes of hepatitis C virus (HCV) infection. Methods: One thousand six hundred and forty-five cases without HCV infection, 545 cases with HCV clearance, and 783 cases with chronic HCV infection were enrolled. TaqMan probe method was used to investigate genotype rs1061622 (T > G) and rs1061624 (G > A). Two single nucleotide polymorphisms (SNPs) sites were genotyped and haplotypes were constructed to evaluate their relation with the outcome of HCV infection. Results: Logistic regression analysis showed that there was no relation to the two SNPs with HCV infection susceptibility and chronicity (P > 0.05). Haplotype analysis showed that carrier TA had an increased susceptibility to HCV infection [adjusted odds ratio (OR) = 1.15, 95% confidence interval (CI): 1.01 to 1.30, P = 0.038)]. Carrier TA and GG haplotypes were conducive to chronic HCV infection (adjusted OR = 1.28, 95% CI: 1.08 to 1.53, P = 0.006; OR = 1.31, 95% CI: 1.03 to 1.66, P = 0.026). Conclusion: The combinational effects of rs1061622 and rs1061624 in TNFRSF1B gene may increase the risk of HCV chronicity and infection.

Abstract
Endothelial to mesenchymal transformation (EndMT) is a process in which endothelial cells gain a mesenchymal-like phenotype in response to mechanobiological signals that results in the remodeling or repair of underlying tissue. While initially associated with embryonic development, this process has since been shown to occur in adult tissue remodeling including wound healing, fibrosis, and cancer. In an attempt to understand the role of EndMT in cancer progression and metastasis, we present a multiscale, three-dimensional, in silico model. The model couples tissue level phenomena such as extracellular matrix remodeling, cellular level phenomena such as migration and proliferation, and chemical transport in the tumor microenvironment to mimic in vitro tissue models of the cancer microenvironment. The model is used to study the presence of EndMT-derived activated fibroblasts (EDAFs) and varying substrate stiffness on tumor cell migration and proliferation. The simulations accurately model the behavior of tumor cells under given conditions. The presence of EDAFs and/or an increase in substrate stiffness resulted in an increase in tumor cell activity. This model lays the foundation of further studies of EDAFs in a tumor microenvironment on a cellular and subcellular physiological level.

Abstract
Objective: To explore the relationship between the tumor necrosis factor receptor superfamily members 11A (TNFRSF11A) and 11B (TNFRSF11B) gene polymorphisms and the outcome of hepatitis C virus (HCV) infection. Methods: In this case-control study, 749 cases of persistent HCV infection, 494 cases of spontaneous clearance and 1 486 control subjects were included from 2008 to 2016. TaqMan-MGB probe method was used to detect the genotype of TNFRSF11A rs1805034 and TNFRSF11B rs2073617. The genotypes distribution of the two single nucleotide polymorphisms (SNP) were analyzed in different populations. Results: Co-dominant model showed that individuals carrying the rs2073617 CC genotype were prone to have chronic HCV infection, compared with individuals carrying the rs2073617 TT genotype (OR=1.517, 95%CI: 1.055-2.181, P=0.024). Recessive model results showed that individuals carrying rs2073617 CC genotype were more likely to develop chronic HCV infection compared with individuals carrying rs2073617 TT or TC genotype (OR=1.435, 95%CI: 1.033-1.996, P=0.032). Additive model showed that the risk for chronic HCV infection increased with the increase of the number of rs2073617 C alleles (OR=1.204, 95%CI: 1.013-1.431, P=0.035). Conclusion: The genetic polymorphism of TNFRSF11B rs2073617 might be related with the chronicity of HCV infection.

Abstract
Objective: To understand the serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), and thyroxine (T4) and identify the related influencing factors of thyroid dysfunction in drug users. Methods: From June to August 2018, a face-to-face questionnaire survey was conducted in 788 male drug users in a drug rehabilitation center in Jiangsu province to collect their socio-demographic information. Then, venous blood sample was collected from each participant for the detection of various hematological indicators, such as thyroid hormones. Results: The abnormal rates of T3, T4, FT3, FT4 and TSH were 4.57%, 1.27%, 0.51%, 0.38% and 0.89%, respectively, in the male drug users. HCV infection was an influencing factor for abnormal T3 level in the male drug users (OR=8.52, 95%CI: 2.36-30.74, P=0.001). And serum T3 (P<0.001) and T4 (P=0.048) levels increased with increasing HCV viral load. Conclusions: HCV infection was an influencing factor for the abnormality of serum T3 level in drug users. Therefore, thyroid-related knowledge should be added in the health education for drug users, and the monitoring of thyroid function should be strengthened for drug users infected with HCV.

Abstract
Abstract
Background
Lifelong antithrombotic therapy is necessary for patients undergoing mechanical valve replacement. However, the optimal regimen and duration of antithrombotic agents are still controversial for patients underwent bioprosthetic valve replacement.
Purpose
We investigated the effect of different antithrombotic strategies on the prognosis of patients underwent bioprosthetic valve replacement in the elder Asian population.
Methods
Based on the National Health Insurance Database in Taiwan, 1227 patients elderly than 50 years-old and underwent bioprosthetic valve replacement between 2003 to 2010 were enrolled for analysis. Patients were classified according to their antithrombotic therapies within 3 months after bioprosthetic valve replacements.
Results
The 1227 patients were stratified to three groups, including aspirin alone (19.6%), warfarin alone (60.6%), and the combined use of aspirin and warfarin (19.9%) within 3 months after surgery. After adjusting propensity scores, the warfarin group (relative risk: 0.69, 95% CI: 0.54–0.88) and the combination group (relative risk: 0.57, 95% CI: 0.42–0.79) both had lower mortality rate compared to the aspirin alone group. Neither increasing major bleeding risk (adjusted relative risk: 0.62, 95% CI: 0.15–2.68) nor decreasing ischemic stroke risk (adjusted relative risk: 0.64, 95% CI: 0.36–1.14) was noticed in the combination group.

Conclusion
Comparing with aspirin alone, warfarin only or combined warfarin with aspirin therapy have a lowering one-year all-cause mortality rate without increasing the occurrence of bleeding events.

Abstract
Abstract
Background
Vitamin D deficiency had been suggested to be the risk factor of cardiovascular diseases and metabolic disorders. However, current evidence about the association between vitamin D deficiency and atherosclerosis are conflicted and inconclusive.
Purpose
We tried to investigate the relationship between serum vitamin D concentrations and subclinical atherosclerosis in the elderly Asian population.
Methods
The I-Lan longitudinal study (ILAS), 1798 community-dwelling adults older than 50 years old were enrolled and divided into two groups according to serum vitamin D level (sufficient, ≥20 ng/mL, and deficient <20 ng/mL). The concentrations of serum vitamin D3 was measured by chemiluminescence immunoassay and demographic data recorded from chart review. The carotid intima-media thickness (cIMT) was measured at bilateral common carotid arteries. Subclinical atherosclerosis was defined as mean cIMT more than 0.81mm, which had been proved to be associated with an increased risk of stroke and coronary events.
Results
Subjects with vitamin D deficiency (n=604, 33.6%) were younger, composed of more woman, smoker, with a higher incidence of hypertension, dyslipidemia, and metabolic syndrome. Compared with subjects without vitamin D sufficiency, patients with vitamin D deficiency were associated with lower risk of subclinical atherosclerosis (crude OR: 0.63, 95% CI: 0.50–0.81, p<0.001) in the univariate analysis. However, after adjusting gender and age, vitamin D deficiency was no more associated with risk of subclinical atherosclerosis.
Risk of vitD3 and cIMT Subclinical Atherosclerosis (cIMT >0.8mm) Odds Ratio 95% Confidence Interval p-value Model 1 Vit D3 normal (≥20) Reference – – Vit D3 deficiency (<20) 0.63 0.50–0.81 <0.001 Model 2 Vit D3 normal (≥20) Reference – – Vit D3 deficiency (<20) 0.81 0.62–1.06 0.127 Model 3 Vit D3 normal (≥20) Reference – – Vit D3 deficiency (<20) 0.93 0.69–1.24 0.599 Model 1: adjust for vit D3 (univariate); Model 2: adjusted for age, vit D3, Gender; Model 3: adjusted multivariate significantly in univariate analysis.
Conclusion
Vitamin D deficiency was not an independent risk factor for subclinical atherosclerosis in the elderly Asian population. The association observed in the univariate analysis may be confounded by gender difference or comorbidities.
