Abstract
Glycosylation is a common post-translational modification in eukaryotic cells. It is involved in the production of many biologically active glycoproteins and the regulation of protein structure and function. Core fucosylation plays a vital role in the immune response. Most immune system molecules are core fucosylated glycoproteins such as complements, cluster differentiation antigens, immunoglobulins, cytokines, major histocompatibility complex molecules, adhesion molecules, and immune molecule synthesis-related transcription factors. These core fucosylated glycoproteins play important roles in antigen recognition and clearance, cell adhesion, lymphocyte activation, apoptosis, signal transduction, and endocytosis. Core fucosylation is dominated by fucosyltransferase 8 (Fut8), which catalyzes the addition of α-1,6-fucose to the innermost GlcNAc residue of N-glycans. Fut8 is involved in humoral, cellular, and mucosal immunity. Tumor immunology is associated with aberrant core fucosylation. Here, we summarize the roles and potential modulatory mechanisms of Fut8 in various immune processes of the gastrointestinal system.

Abstract
Objective: To investigate the effect of rosiglitazone (RGZ) on the expression of peroxisome proliferator-activated receptor gamma (PPARγ) and heme oxygenase-1 (HO-1) in hepatic stellate cells (HSCs). Methods: In vitro activated hepatic stellate cell-T6 (HSC-T6) as research subjects were divided into blank control group, RGZ intervention group, and RGZ + ZnPP-IX mutual intervention group. MTT colorimetry method was used to measure the condition of cell proliferation. ELISA was used to detect the content of hyaluronic acid (HA) and type III procollagen peptide (PIIIP) in the cell supernatant. Real-time quantative PCR, western blot and immunocytochemistry were used to detect the relative expression levels of PPARγ, HO-1 mRNA and protein. One-way analysis of variance was used to compare the sample mean between multiple groups, and LSD test was used for comparison between two groups. Results: The proliferation activity of HSC-T6 and the expressions of HA and PIIIP in the RGZ intervention group were significantly lower than those in the blank control group (P < 0.01), but the relative expression levels of PPARγ and HO-1 mRNA and protein were significantly increased compared with the blank control group (PPARγ : 2.97 ± 0.22 vs. 1.07 ± 0.05, 0.96 ± 0.08 vs. 0.31 ± 0.03; HO-1: 4.28 ± 0.73 vs. 1.80 ± 0.36, 1.83 ± 0.26 vs. 0.61 ± 0.09), and the difference was statistically significant (P < 0.01). The proliferation activity of HSC-T6 and the expression of HA and PIIIP was higher in RGZ + ZnPP-IX mutual intervention group as compared with RGZ group (P < 0.05). HO-1 mRNA (3.16 ± 0.38 vs. 4.28 ± 0.73) and protein (1.31 ± 0.17 vs. 1.83 ± 0.26) relative expression levels was decreased, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the relative expression of PPARγ mRNA and protein (P > 0.05), however, there was a decreasing trend. HO-1 mRNA (1.80 ± 0.36) and protein (0.61 ± 0.09) relative expression was significantly increased in RGZ + ZnPP-IX group as compared to blank control group (P < 0.05). Immunocytochemical staining had consistency with the above results. Conclusion: The effect of rosiglitazone on inducing increased expression of PPARγ, and then inhibiting HSC proliferation activity and collagen production may be realized by regulating its downstream HO-1 expression.

Abstract
Background Thyroid hormone participates in lipid metabolism regulation. However, the effects on triacyleride or triacylglycerol metabolism are complex and not fully clarified yet. In this study, we try to identify novel thyroid hormone-targeting lipogenic metabolic genes and analyze their molecular regulative mechanism. Method Thirty-five promoters of twenty-nine human lipogenic regulative enzyme genes were constructed into pXP1 luciferase reporter plasmid (PFK2/FBP2-luc) and transfected into HeGP2 cells, respectively. Gene expression induced by triiodothyronine (T3) was detected by luciferase assay. The T3-activated gene promoter was then analyzed by sequence analysis, deletion and mutation, and electrophoretic mobility shift assay (EMSA). Results After 10 nM T3 stimulation for 36 h, phosphogluconate dehydrogenase, malic enzyme, Glycerol-3-phosphate acyltransferase (GPAT) 3, and 1-acylglycerol-3-phosphate O-acyltransferase (AGPAT) 2 were significantly activated, respectively. A AGGTCA-like-direct-repeat-4 consensus thyroid hormone response element (DR4-TRE)-like sequence was found in the GPAT3 promoter, which was then verified to be necessary for T3-induced GPAT3 activation by gene deletion and mutation analysis. EMSA further identified that T3-thyroid receptor (TR) α-retinoid-X receptor (RXR) complex directly bound on the GPAT3 promoter. Conclusion Triiodothyronine could activate the GPAT3 through DR4-TRE-like sequence binding to participate in lipogenic regulation. AGPAT2 may be another thyroid hormone target enzyme.

Abstract
Objective: To compare the efficacies of the two techniques of "micro-hemostasis and micro-cutting" with straight bipolar electrocoagulation forceps and traditional clamp-ligation for hemostasia in thyroid surgery. Methods: A total of 228 patients who underwent surgical treatment for thyroid neoplasms in our hospital between January 2015 and December 2018 were retrospectively analyzed, including 50 males and 178 females, aged 23-68 years old. Of those, 150 cases as electric knife group received traditional thyroid surgery between January 2015 and December 2018 and 78 cases as bipolar electrocoagulation group received thyroid surgery by using the technique of bipolar electrocoagulation with meticulous anatomy between January 2018 and December 2018. The total operation time, single operation time, intraoperative hemorrhage, postoperative drainage volume on the first day, postoperative hoarseness and hypocalcemia were compared between the two groups. SPSS 16.0 was used to analyze the data. Results: The total operation time and intraoperative hemorrhage in the bipolar electrocoagulation group were significantly lower than those in the electric knife group ((59.33±18.29)min vs (77.21±25.39)min, (14.83±9.22)ml vs (36.86±11.80)ml, all P<0.01). The single operation time of the bipolar electrocoagulation group was shorter than that of the electric knife group((10.25±6.16) min vs (20.34±7.24)min, (16.25±7.15)min vs (35.68±8.25)min, (12.12±5.25)min vs (20.68±7.26)min, t value was 3.948,16.262,8.238, all P<0.01).There was no significant difference between the two groups in postoperative drainage volume on the first day (P>0.05) and the incidence of postoperative hoarseness (P>0.05), while the incidence of hypocalcemia in the bipolar electrocoagulation group(10.26%) was lower than that in the electric knife group(21.33%,χ(2)=4.353, P<0.05). Conclusions: The fine dissection for thyroid operation can be achieved by using straight bipolar electrocoagulation tweezers. The use of "micro-hemostasis" and "micro-cutting" technique with bipolar electrocoagulation tweezers can greatly reduce intraoperative bleeding, operation time and postoperative complication.

Abstract
Purpose This study investigated the clinical outcomes and safety of apatinib mesylate in the treatment of advanced non-squamous non-small cell lung cancer (NSCLC) in patients who progressed after standard therapy, and analyzed the kinase insert domain receptor (KDR) gene polymorphism. Methods A total of 135 patients with advanced non-squamous NSCLC who received apatinib mesylate were included. Objective response rates were evaluated. Subsequently, progression-free survival (PFS) and overall survival (OS) were assessed and safety data were recorded. Additionally, peripheral blood and biopsy cancer tissue specimens were collected from the patients with NSCLC for the genotyping of the genetic polymorphism and mRNA expression of the KDR gene, respectively. Analysis on the association between genotypes and prognosis was conducted. Results The objective response rate of the 135 patients with NSCLC was 18.52%, disease control rate was 65.19%, median PFS was 3.95 months, and median OS was 10.05 months. Regarding the KDR gene polymorphism analysis, the distribution of the 4397T>C polymorphism genotypes was in accordance with the Hardy–Weinberg Equilibrium (P=0.868). Moreover, the prognosis analysis indicated that the median PFS of patients with the CC/TC and TT genotypes was 2.80 and 4.80 months, respectively (P=0.002). Furthermore, the median OS of patients with the two genotypes was 9.10 and 10.56 months, respectively (P=0.041). The multivariate Cox regression analysis showed that the TC/CC genotypes were an independent factor for PFS (odds ratio: 1.72, P=0.009). There was no correlation between the polymorphism and adverse reactions. Additionally, the mRNA expression analysis suggested that the mRNA levels of KDR in cancer tissues were significantly different between the TT and TC/CC genotypes (P<0.001). Conclusion The clinical outcomes of treatment with apatinib mesylate for advanced non-squamous NSCLC in patients who progressed after standard therapy may be influenced by the KDR 4397T>C polymorphism through mediation of the mRNA expression of KDR.

Abstract
Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion: In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.

Abstract
Objective: To observe the therapeutic effects and related mechanism of hemin on the progression of hepatic fibrosis in rats. Methods: Sixty male Wistar rats were randomly divided into normal control group, 4-week model group, 6-week model group, hemin inhibitor zinc protoporphyrin-IX (ZnPP-IX) intervention group and hemin intervention group. Hemin intervention group in complex liver fibrosis model was intraperitonealy administered ZnPP-IX or hemin every other day for 2 weeks from the fourth week. The mRNA expression of HO-1, α-smooth muscle actin (α-SMA) and nuclear factor-κB (NF-κB) in the liver tissue was detected by real-time polymerase chain reaction. Immunohistochemistry was used to detect HO-1 and localization of α-SMA expression. Serum hyaluronic acid, propeptide of type III collagen and hepatic transforming growth factor beta (TGFβ), and interleukin 6 (IL-6) expressions were detected by enzyme-linked immunosorbent assay. The content of hydroxyproline in hepatic tissues was measured by alkaline hydrolysis method. One-way ANOVA was used to compare the mean of each group. The difference between the two groups was compared by independent samples t- test. P-values < 0.05 was considered statistically significant. Results: Compared with model groups and ZnPP-IX intervention group, Hemin's intervention significantly increased the expression of HO-1 mRNA (P < 0.01) and protein distribution in liver tissues, while the expression of alpha-SMA mRNA was significantly decreased (P < 0.05) in portal space and areas around the fibrotic septum, and hepatic sinus. Hyp content and serum hyaluronic acid and propeptide of type III collagen decreased significantly (P < 0.05). Meanwhile, NF-κB p65 mRNA expression and the downstream production of TGFβ and IL-6 in Hemin intervention group were also inhibited (P < 0.05). Conclusion: Hemin can significantly inhibit the progression of hepatic fibrosis in rats by up-regulating HO-1 expression, and the inhibiting activity of NF-κB p65 leads to downstream of the inflammatory factors.

Abstract
Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion: In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Abstract
The aim of this study was to evaluate the effects of plant roots (Typha angustifolia roots) on the hydraulic performance during the clogging process from the perspective of time and space distributions in mesocosm vertical flow-constructed wetlands with coarse sand matrix. For this purpose, a pair of lab-scale experiments was conducted to compare planted and unplanted systems by measuring the effective porosity and hydraulic conductivity of the substrate within different operation periods. Furthermore, the flow pattern of the clogging process in the planted and unplanted wetland systems were evaluated by their hydraulic performance (e.g., mean residence time, short circuiting, volumetric efficiency, number of continuously stirred tank reactors, and hydraulic efficiency factor) in salt tracer experiments. The results showed that the flow conditions would change in different clogging stages, which indicated that plants played different roles related to time and space. In the early clogging stages, plant roots restricted the flow of water, while in the middle and later clogging stages, especially the later stage, growing roots opened new pore spaces in the substrate. The roots played an important role in affecting the hydraulic performance in the upper layer (0-30 cm) where the sand matrix had a larger root volume fraction. Finally, the causes of the controversy over plant roots' effects on clogging were discussed. The results helped further understand the effects of plant roots on hydraulic performance during the clogging process.

Abstract
Oxygen is known to be released from plant roots, but has seldom been quantified for wetland plants. Our study aims to quantify oxygen release from the roots of one wetland species in China, and use this knowledge as a basis for future modeling. We measured diurnal fluctuations in oxygen release from the roots of Acorus calamus Linn in a modeled constructed wetland (CW) using a titanium ([image omitted]) citrate buffer. Oxygen release was monitored every two hours. Maximum oxygen release was recorded in the range of 215.2-750.8 μmolg(-1)h(-1) and occurred around 15:00. The maximum value of photosynthetically active radiation (PAR) was in the range of 1281.8-1712.0 mmolm(-2)s(-1) and occurred around 13:00. Both the oxygen release rate and PAR were found to approach zero at night. Our results indicate that oxygen release depends largely on light intensity and exhibits a diurnal periodicity with release occurring only during daytime. Rate of root oxygen release varied during the daytime and this temporal variation was well described by the Gaussian function. While further validation is needed, we suggest that the Gaussian function may be used as the basis for modeling root oxygen release in natural and constructed wetlands.

Abstract
Substrate clogging caused by the accumulation of the particulate solids is the worst operational problem for vertical-flow constructed wetlands (VFCW). In this paper, the effects of particulate solids distribution and their accumulation in the substrate with different gravel sizes were investigated. The results demonstrated that the clogging layer can be considered as two parts: one is the blanket-like deposition layer, and the other is the upper substrate clogging layer. Furthermore, the clogging process shall be partitioned as three stages of puncture phase for the pollutants; the formation of the blanket-like deposition layer; and the formation and compaction phase to the whole clogging layer. With reference to the clogging mechanism, it is believed that the particulate solids (< 100 microm) were absorbed firstly by electrostatic forces and van der Waals' forces. This is followed by the "bridging" made by the accumulated solids which act as a "sieve", thus further restricting larger particulate solids to flow through.

Abstract
Liuwei Dihuang Decoction is a representative classic prescription for nourishing Yin in Traditional Chinese Medicine. Experimental and clinical studies showed that the recipe could 1. inhibit carcinogenesis of anterior stomach by N-nitrososarcosine ethyl ester in mice; 2. inhibit the formation of lung tumors induced by Urethan in mice; 3. decrease spontaneous tumorigenesis in LACA strain; 4. inhibit the mutagenic activity of Endoxan in micronuclear test. Patients with epithelial dysplasia of esophagus, a preneoplastic lesion, were treated by using this recipe. The canceration rate within 1 year was 2.2% in the treated and 12.4% in an untreated group. Within 5 years these rates were 9% and 26% respectively (p less than 0.025).
