Abstract
Virus-like particles encapsulating HBV-RNA represent a serum biomarker for assessing viral replication activity in clinical practice. However, baseline levels of serum HBV-RNA and their associations with viral replicative intermediates and liver disease in phases of chronic hepatitis B remain unknown. In this cross-sectional study, 102 patients were categorized into immune-tolerant (IT), HBeAg-positive immune active (HBeAg+IA), inactive carrier (IC) and HBeAg-negative immune active (HBeAg-IA) phases. HBV-RNA in serum samples and in 66 paired liver biopsies were quantified and correlated with serum ALT levels, histopathological scores and the levels of other viral replicative intermediates. Mean levels of serum HBV-RNA differed among phases, with the highest levels among IT (6.78 ± 0.83 log10 copies mL-1 ) patients, followed by HBeAg+IA (5.73 ± 1.16 log10 copies mL-1 ), HBeAg-IA (4.52 ± 1.25 log10 copies mL-1 ) and IC (2.96 ± 0.40 log10 copies mL-1 ) patients. Serum HBV-RNA levels correlated with HBV DNA in all phases, although correlations with other viral replicative intermediates weakened or disappeared when cases were stratified into phases. Distinct compositions of viral products were found among phases: the ratio of HBsAg to serum HBV-RNA was highest in IC patients, while the ratio of serum HBV-RNA to intrahepatic HBV-RNA and the ratio of intrahepatic HBV-DNA to intrahepatic HBV-RNA were significantly higher in IT patients. In conclusion, baseline levels of HBV-RNA and the composition of viral replicative intermediates differ significantly across the natural course of chronic HBV infection. These findings shed light on the nature of viral replication and pathogenesis of disease among different phases of chronic HBV infection.

Abstract
Background/Aims: To identify new treatment strategies for gastric cancer and to elucidate the mechanism underlying its pathophysiology, we transfected sh-MARCH8 into the human gastric cancer cell lines MKN-45 and AGS to investigate the roles of MARCH8 in gastric cancer. Methods: We used genetic engineering to construct the sh-MARCH8 interference plasmid and transfected it into gastric cancer cells. Colony formation assays and cell viability measurements were performed to detect the viability and proliferation of cancer cells. Wound healing assays were performed to estimate the migration and proliferation rates of the cells. Cell invasion assays were used to estimate the invasive abilities of the cells. Cell apoptosis analysis was performed by using flowing cytometry. Western blot analysis was performed to estimate the expression levels of proteins. Statistical analysis was performed using the SPSS 18.0 software. Student’s t-test was used to determine the significance of all pairwise comparisons of interest. Results: We observed that the transfection of sh-MARCH8 inhibited the survival and proliferation of MKN-45 and AGS cells. The migration and invasion of the MKN-45 and AGS cells were significantly decreased, and apoptosis was induced in comparison with the control cells. These results were further confirmed by data showing that sh-MARCH8 increased the BAX/BCL2 ratio in MKN-45 and AGS cells. We also observed that sh-MARCH8 inactivated the PI3K and ß-catenin stat3 signaling pathways by changing protein expression levels or the phosphorylation of related proteins. Conclusion: These data suggested that sh-March8 reduced viability and induced apoptosis of the MKN-45 and AGS cells through the PI3K and ß-catenin stat3 signaling pathways. Taken together, our data revealed that transfection of sh-MARCH8 into the MKN-45 and AGS gastric cancer cell lines inhibited their growth, and this approach may be useful as a novel strategy for gastric cancer therapy.

Abstract
We propose an incident direction independent wave propagation generated by properly assembling different unidirectional destructive interferences (UDIs), which is a consequence of the appropriate match between synthetic magnetic fluxes and the incident wave vector. Single-direction lasing at spectral singularity is feasible without introducing nonlinearity. UDI allows unidirectional lasing and unidirectional perfect absorption; when they are combined in a parity-time-symmetric manner, the spectral singularities vanish with bounded reflections and transmissions. Furthermore, the simultaneous unidirectional lasing and perfect absorption for incidences from opposite directions is created. Our findings provide insights into light control and may shed light on the explorations of desirable functionality in fundamental research and practical applications.

Abstract
We study the Kitaev model on a finite-size square lattice with periodic boundary conditions in one direction and open boundary conditions in the other. Based on the fact that the Majorana representation of Kitaev model is equivalent to a brick wall model under the condition t = Δ = μ, this system is shown to support perfect Majorana bound states which is in strong localization limit. By introducing edge-mode fermionic operator and pseudo-spin representation, we find that such edge modes are always associated with maximal entanglement between two edges of the tube, which is independent of the size of the system.

Abstract
Some evidences have been provided to verify the effects of lncRNA NNT-AS1 on cancer progression. However, the crucial impacts of NNT-AS1 on the malignancy of breast cancer have not been elaborated. This study aims to detect the expression pattern and functional effects of NNT-AS1 in breast cancer. qRT-PCR analysis was applied to detect the expression of NNT-AS1 in both BC tissues and matched normal tissues. Loss of function assay was carried out to detect the effects of silenced NNT-AS1 on proliferation, metastasis and EMT process of BC cells. To understand the functional mechanism of NNT-AS1, mechanism assays were designed and performed in BC cells. Subcellular fractionation assay demonstrated that NNT-AS1 was located in the cytoplasm of BC cells. Therefore, NNT-AS1 might exert ceRNA functions in BC cells. To validate this hypothesis, we found the combination between NNT-AS1 and miR-142-3p through conducting bioinformatics analysis, RIP and luciferase reporter assays. Similarly, the combination between miR-142-3p and ZEB1 was verified. Finally, the recue assays were carried out to demonstrate the effects of NNT-AS1/miR-142-3p/ZEB1 axis on the biological behaviors of BC cells. All the above findings revealed a fact that NNT-AS1 affects breast cancer progression through modulating miR-142-3p/ZEB1 axis.

Abstract
OBJECTIVE To explore the clinical efficacy of sequential therapy with voriconazole on chronic obstructive pulmonary disease (COPD) patients in acute phase with pulmonary aspergillosis and its effects on cytokines and pulmonary functions. PATIENTS AND METHODS A total of 110 COPD patients in acute phase with pulmonary aspergillosis who were admitted to the hospital between February 2015 and November 2016 were enrolled. We divided them randomly into two groups, i.e., the control group (n = 55) and the treatment group (n = 55). Patients in the control group took itraconazole capsules orally (200 mg/time, twice per day for three days followed by once per day). Patients in treatment group underwent sequential treatment with voriconazole through intravenous infusion at a dose of 5 mg/kg/time twice a day for 3 days followed by a dose of 4 mg/kg/time, twice a day for 8 days. Then, patients took voriconazole orally at a dose of 150 mL/time, twice a day for 6 days. Patients in two groups received the treatment for a total of 14 days. After treatment, we evaluated the levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), and IL-8. The total lung capacity (TLC), diffusing capacity of the lung for carbon monoxide (DLco), and arterial oxygen saturation (SaO2), were measured as well. RESULTS The total effectiveness rates of the treatment group and the control group were 83.63% and 61.82%. The differences had statistical significance (p < 0.01). After treatment, the incidence of chest pain, cough, sputum-coughing, hemoptysis, cyanosis, and dyspnea in the treatment group was significantly fewer than that in the control group (p < 0.05). TCL, DLco, and SaO2 in the two groups were significantly ameliorated by treatment (p < 0.05). The amelioration in the treatment group was more prominent than that in the control group (p < 0.05). The levels of TNF-α, IL-8, and IL-6 in the two groups were decreased dramatically by the treatments. The decrease in the treatment group was significantly lower than those in the control group (p < 0.05). Occurrence of adverse reactions in treatment group and control group were 8.33% and 6.25%, respectively; (p > 0.05). CONCLUSIONS Sequential therapy with voriconazole exhibits promising clinical efficacy in COPD patients in acute phase with pulmonary aspergillosis. The treatment ameliorated the clinical symptoms and vital signs of patients significantly. It also improved the pulmonary functions and inhibited the inflammatory responses of patients with evident clinical efficacy.

Abstract
CD3+ CD20+ T cells are a population of CD3+ T cells that express CD20 and identified in healthy donors and autoimmune diseases. However, the nature and role of these cells in patients with psoriasis remain unclear. In this study, we aimed to investigate the level, phenotype, functional and clinical relevance of CD3+ CD20+ T cells in the peripheral blood of patients with psoriasis. We found that a small subset of CD3+ T cells expressed CD20 molecule in the peripheral blood of patients with psoriasis, and their levels were similar to those in healthy donors. Circulating CD3+ CD20+ T cells in patients with psoriasis were enriched in CD4+ cells and displayed an activated effector phenotype, as these cells contained fewer CD45RA+ -naive and CCR7+ cells with increased activity than those of CD3+ T cells lacking CD20. In addition, compared with healthy donors, circulating CD3+ CD20+ T cells in patients with psoriasis produced more cytokines, interleukin (IL)-17A, tumour necrosis factor (TNF)-α and IL-21, but not IL-4 and IFN-γ. Furthermore, a significantly positive correlation was found between the levels of IL-17A, TNF-α and IL-21-production CD3+ CD20+ T cells with Psoriasis Area and Severity Index scores. Our findings suggest that CD3+ CD20+ T cells may play a role in the pathogenesis of psoriasis.

Abstract
Objective: To observe the immunoreaction of offspring mice by ovalbumin (OVA) re-exposure after their mothers exposed to OVA during pregnancy. Method: A prospective controlled study was conducted to observe mice after repeated OVA exposures at 6-8 weeks.Their mothers were exposed to OVA during different stages of pregnancy.The symptoms were recorded and scored.The levels of OVA-specific IgE in serum, interferon-γ(IFN-γ) and interleukin-4(IL-4) in supernatant of spleen primary lymphocytes in vitro were measured by ELISA.The results were analyzed by single factor analysis of variance or rank sum test. Result: All the mice in each group had acute diarrhea.The diarrhea happened earliest (2 days) and most severe in the late pregnancy group (early pregnancy group 7.0±1.0; middle pregnancy group: 7.1±1.1; late pregnancy group: 9.9±2.2, P<0.01). The levels of absorbance of OVA-specific IgE in the pregnancy groups were higher than those of the control group.The absorbance of OVA-specific IgE in late pregnancy group was the highest (control: 0.27±0.06; early pregnancy group: 0.51±0.13; middle pregnancy group: 0.50±0.09; late pregnancy group: 0.63±0.13, P<0.01). There was no significant change in IFN-γ expression in cultured supernatant of spleen lymphocytes in each group (control: (133±7) pg/ml; early pregnancy group: (133±4) pg/ml; middle pregnancy group: (134±6) pg/ml; late pregnancy group: (132±4) pg/ml, all P value >0.05). The expression of IL-4 in the experimental groups was higher than that in the control group, especially in late pregnancy group(control: (25.3±2.4) pg/ml; early pregnancy group: (32.4±4.4) pg/ml; middle pregnancy group: (35.0±5.4) pg/ml; late pregnancy group: (47.1±5.8) pg/ml; P value all<0.01). Conclusion: The allergic reaction of the OVA re-exposure progeny whose mothers were exposed to OVA in the late pregnancy period was most severe, suggesting that late pregnancy period might be the high risk stage of intrauterine sensitization, or"window period".

Abstract
PURPOSE Abdominal wall defects caused by neoplasms with large extended resection defects remain a challenging problem. Autologous flaps, meshes, and component separation techniques are effective in reconstructing these defects. We retrospectively reviewed and assessed the success of reconstruction using tensor fascia lata flap with or without meshes. METHODS 18 patients with abdominal wall neoplasms were identified during the period from 2007 to 2016. A retrospective review of office charts and hospital records was performed. RESULTS A total of 18 patients received corresponding treatment according to the degree of defects, with a mean age of 53.89 ± 14.56 years old, a mean body mass index (BMI) of 22.89 ± 4.09 kg/m2, and a mean American Society of Anesthesiologist (ASA) score of 2.18 ± 0.75. Operative details included the mean defect size (303.44 ± 175.67 cm2), the mean mesh size (265.92 ± 227.99 cm2), and the mean operative time (382.33 ± 180.38 min). Postoperative wound complications were identified in 7 (39%) patients, including incisional infection, edema and thrombus. Neoplasm recurrence was observed in 2 (13%) primary neoplasms patients. No hernias were present in any patient. CONCLUSIONS Abdominal wall defects caused by neoplasms should be repaired by autologous flaps combined with or without mesh reinforcement. Most type I defects should be primary sutured; type II or III defects should be repaired well by flaps, with or without mesh; if the incision is infected or contaminated, biological mesh or flaps are the best choice.

Abstract
BACKGROUND/AIMS MicroRNA-21 is an oncogenic miR (oncomiR) frequently elevated in gastric cancer (GC). Overexpression of miR-21 decreases the sensitivity of GC cells to 5-fluorouridine (5-Fu) and trastuzumab, a humanized monoclonal antibody targeting human epidermal growth factor receptor 2 (HER2). Receptor-mediated endocytosis plays a crucial role in the delivery of biotherapeutics including anti-miRNA oligonucleotides (AMOs). This study is a continuation of earlier findings involving poly(ε-caprolactone) (PCL)-poly (ethylene glycol) (PEG) nanoparticles (PEG-PCL NPs), which were coated with trastuzumab to target GC with HER2 receptor over-expression using anti-miRNA-21 (AMO-21) and 5-Fu. METHODS HER-PEG-PCL NPs were prepared by one-step carbodiimide coupling using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDAc) and Sulfo-NHS in aqueous phase. Covalent coupling of amino groups at the surface of PEG-PCL with the carboxyl groups of trastuzumab was analyzed by X-ray photoelectron spectroscopy (XPS). AMO-21/5-Fu NPs were formulated by a double-emulsion solvent evaporation technique. The cell line specificity, cellular uptake and AMO-21 delivery were investigated through the rhodamine-B-labeled 6-carboxyfluorescein (FAM)-AMO-21-PEG-PCL NPs coated with or without the antibody in both Her2-positive (NUGC4) and negative GC cells (SGC7901) visualized by fluorescence microscopy. The cytotoxicity of the HER-PEG-PCL NPs encapsulating AMO-21 was evaluated by MTT and apoptosis. Real-time reverse-transcription polymerase chain reaction (RT-PCR) was used to examine miR-21 and phosphatase and tensin homolog (PTEN) and Sprouty2 expression in GC cell lines. The antitumor effects of AMO-21/5-Fu NPs were compared with other groups in xenograft gastric cancer mice. RESULTS The antibody conjugates significantly enhanced the cellular uptake of NPs. The AMO-21/5-Fu NPs effectively suppressed the target miRNA expression in GC cells, which further up-regulated PTEN and Sprouty2. As a result, the sensitivity of HER2-expressing gastric cancer to trastuzumab and 5-Fu were enhanced both in vitro and in vivo. The approach enhanced the targeting by trastuzumab as well as antibody-dependent cellular cytotoxicity (ADCC) of immune effector cells Conclusions: Taken together, the results provide insight into the biological and clinical potential of targeted AMO-21 and 5-Fu co-delivery using modified trastuzumab for GC treatment.

Abstract
We study the topological feature of gapless states in the fermionic Kitaev model on a square lattice. There are two types of gapless states which are topologically trivial and nontrivial. We show that the topological gapless phase lives in a wide two-dimensional parameter region and are characterized by two vertices of an auxiliary vector field de-fined in the two-dimensional momentum space, with opposite winding numbers. The isolated band touching points, as the topological defects of the field, move, emerge, and disappear as the parameters vary. The band gap starts to open only at the merg-ing points, associated with topologically trivial gapless states. The symmetry protect-ing the topological gapless phase and the robustness under perturbations are also discussed.

Abstract
BACKGROUND Studies from high-income countries report moderate-to-strong positive associations between alcohol use disorder (AUD) and other mental disorders, but there is little evidence about the comorbidity of AUD from low-and-middle-income countries. METHODS A sample of 74 752 adults from five provinces that account for >12% of China's adult population was screened using the General Health Questionnaire, and the Structured Clinical Interview for DSM-IV was administered by psychiatrists to a subsample of 9619 males. The associations between AUD and other mental disorders at each site and the characteristics of men with AUD with and without comorbid mental disorders were estimated using logistic regression and summarized across sites using meta-analysis. Generalized estimation equations estimated the associations between the clinical features of alcohol dependence and comorbidity. RESULTS Robust inverse associations were found between current AUD and any mood disorder (adjusted OR = 0.6, 95% CI = 0.4-0.8) and any anxiety disorder (OR = 0.5, 95% CI = 0.3-1.0). Compared with men without AUD, men with AUD without comorbid disorders were more likely to be middle-aged, to be currently married, and to have higher family incomes. Men with comorbid AUD and other disorders were more likely to have the clinical features of alcohol dependence than men with AUD without comorbid disorders. CONCLUSIONS Inverse associations between AUD and other mental disorders and the higher social status of men with AUD than men without AUD found in this large, representative sample of community-dwelling Chinese males highlight the importance of considering the local substance-use culture when designing clinical or preventive interventions for addictive conditions.
