Abstract
BACKGROUND Peginterferon induces off-treatment responses in approximately one-third of patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. AIM To develop an easy-to-use baseline prediction score to identify hepatitis B virus (HBV) genotype B-/C-infected HBeAg-positive Asian patients likely to respond to peginterferon alfa-2a. METHODS Generalised additive models, multiple logistic regression (MLR) analysis and internal validation methods were applied to data from 647 HBeAg-positive patients from China, Hong Kong and Taiwan to develop a scoring system to predict response 24 weeks after completing a 48-week course of peginterferon alfa-2a. RESULTS Five baseline factors (age, sex, alanine aminotransferase ratio, hepatitis B surface antigen (HBsAg) level and HBV DNA level) were retained in the final MLR for HBeAg seroconversion and used to develop a scoring system from 0 to 7. Among patients with scores of 0-1, 2-3, 4 or ≥5, HBeAg seroconversion was achieved in 6.4% (6/94), 23.0% (61/265), 36.4% (67/184) and 54.8% (57/104), respectively, and a combined response (HBeAg seroconversion plus HBV DNA <2000 IU/mL) in 5.3% (5/94), 12.8% (34/265), 25.0% (46/184) and 36.5% (38/104), respectively. Among patients with scores of 0-1, 2-3, 4 or ≥5, 57.0% (53/93), 12.3% (31/253), 3.4% (6/178) and 1.0% (1/100) had HBsAg ≥20 000 IU/mL at treatment Week 12; only 3/91 (3.3%) with HBsAg ≥20 000 IU/mL experienced a combined response at 24 weeks post-treatment (negative predictive value = 97% [88/91]). CONCLUSION A pre-treatment scoring system using readily available baseline characteristics identifies HBeAg-positive Asian patients likely to experience sustained HBeAg seroconversion after treatment with peginterferon alfa-2a.

Abstract
OBJECTIVE The aim of the present work was to study the prevention of liver cancer angiogenesis via miR-126. For this purpose, experimentations were conducted. MATERIALS AND METHODS The precursor sequence of miR-126 was amplified in the DNA of human liver cancer cell lines. We, therefore, constructed the overexpression and interference vectors of miR-126 in vitro; which were respectively transferred to liver cancer cells in the logarithmic phase and inoculated under both sides of the back skin of Balb/c-nu nude mice aged 4-6 weeks with 10 mu l (1 x 105) cell suspension. The experiment consisted of non-vector control group, miR-126 overexpression group, and miR-126 inhibition group. Eight weeks later, the mice were sacrified; the tumor volumes and serum ALT, AFP, VEGF levels were compared. VEGF expression, as well as the microvascular density of the liver tissues, was detected via immunohistochemistry. RESULTS Tumors volumes, serum ALT, AFP and VEGF levels and positive rates of VEGF were low in the miR-126 overexpression group and high in the miR-126 inhibition group, the difference being statistically significant (p < 0.05). CONCLUSIONS At the end of this study, we conclude that miR-126 inhibits liver cancer angiogenesis.

Abstract
BACKGROUND There is no consensus on the use of thrombus aspiration (TA) in primary percutaneous coronary intervention (PPCI), and few studies have focused on the performance of tirofiban via TA catheter after PPCI. Our study investigated the clinical outcome of tirofiban injection through TA in acute ST-segment elevation myocardial infarction (STEMI) patients with large thrombus burden undergoing PPCI treatment. PATIENTS AND METHODS The study comprised 122 STEMI patients who underwent TA during PPCI. Participants were randomly divided into two groups. Group A received intravenous tirofiban injection and tirofiban injection via a TA catheter to the infarcted coronary artery after aspiration (n = 61). Group B received intravenous tirofiban injection only (n = 61). Baseline clinical information and follow-up data were collected for both groups. Coronary angiography, electrocardiography, and echocardiography findings as well as major adverse cardiovascular events (MACE) were recorded. RESULTS There were significant differences in postprocedural Thrombolysis in Myocardial Infarction (TIMI) grade 2 and 3 flow between the two groups (p = 0.021, p = 0.006, respectively). The incidence of slow-flow in group A was significantly lower than that of group B (p = 0.011). An increased incidence of no ST-segment resolution was observed in group B (p = 0.011). There were fewer major adverse cardiovascular events in group A than in group B, but the difference was not statistically significant. CONCLUSION Selective tirofiban injection via TA catheter during PPCI may improve myocardial reperfusion in STEMI patients with large thrombus burden.

Abstract
BACKGROUND In the large randomised NEPTUNE study, peginterferon alfa-2a 180 μg/wk for 48 weeks produced higher hepatitis B e antigen (HBeAg) seroconversion rates 24 weeks post-treatment (36%) than a lower dose (90 μg/wk) and/or shorter duration (24 weeks) (range 14%-26%). AIM To determine seroconversion rates 5 years after completion of treatment in NEPTUNE. METHODS HBeAg-positive patients who completed 24 weeks' follow-up in NEPTUNE (with peginterferon alfa-2a 90 μg/wk × 24 weeks [group 1]; 180 μg/wk × 24 weeks [2]; 90 μg/wk × 48 weeks [3] or 180 μg/wk × 48 weeks [4]) were followed up. RESULTS Three hundred and eighty three of the 544 patients in the original study were enrolled in the long-term follow-up study. Many patients (196 overall; more in groups 1-3 than 4) received nucleos(t)ide analogues or immunomodulators during follow-up, and more patients had missing data at year 5 in groups 2 and 4 (48 weeks, 50/112) than in groups 1 and 3 (24 weeks, 23/103), which confounds the planned per-protocol analysis. HBeAg seroconversion rates in groups 1, 2, 3 and 4 at year 5 were 47.5%, 50.7%, 52.2% and 67.1%, respectively, (odds ratio for group 4 versus 1-3: 2.02; 95% CI 1.21, 3.38), using multiple imputation methods for missing measurements. CONCLUSION Seroconversion rates are durable for up to 5 years after completion of peginterferon alfa-2a therapy and, consistent with NEPTUNE, the results suggest that the licensed regimen (180 μg × 48 weeks) is more efficacious for HBeAg-positive patients than a lower dose and/or shorter treatment duration.

Abstract
Liver biopsy is not routinely performed in treated chronic hepatitis B. Liver stiffness measurement has been validated for noninvasive liver fibrosis assessment in pretreatment chronic hepatitis B but has not been assessed for fibrosis monitoring during antiviral therapy. Liver stiffness was systemically monitored by Fibroscan® every 6 months in a cohort of patients with hepatitis B receiving antiviral therapy and compared with liver biopsies at baseline and week 104. A total of 534 hepatitis B e antigen-positive treatment-naive patients receiving telbivudine-based therapy with qualified liver stiffness measurement at baseline and week 104 were analyzed, 164 of which had adequate paired liver biopsies. Liver stiffness decreased rapidly (-2.2 kPa/24 weeks) in parallel with alanine aminotransferase (ALT) from 8.6 (2.6-49.5) kPa at baseline to 6.1 (2.2-37.4) kPa at week 24. Interestingly, liver stiffness decreased slowly (-0.3 kPa/24 weeks) but continually from week 24 to week 104 (6.1 vs 5.3 kPa, P < .001) while ALT levels remained stable within the normal range. More importantly, liver stiffness declined significantly irrespective of baseline ALT levels and liver necroinflammation grades. From baseline to week 104, the proportion of patients with no or mild fibrosis (Ishak, 0-2) increased from 74.4% (122/164) to 93.9% (154/164). Multivariate analysis revealed that percentage decline of 52-week liver stiffness from baseline was independently associated with 104-week liver fibrosis regression (odds ratio, 3.742; P = .016). Early decline of 52-week liver stiffness from baseline may reflect the remission of both liver inflammation and fibrosis and was predictive of 104-week fibrosis regression in treated patients with chronic hepatitis B.

Abstract
Acute-on-chronic liver failure (ACLF) is a clinical syndrome characterized by acute decompensation of chronic liver disease associating with multiple organ failures and high short- term mortality. Patients with ACLF are highly susceptible to infection due to the pathophysiology features including immune function disorder (overlap of excessive inflammatory reaction and immune dysfunction), gut bacterial overgrowth/dysbiosis and translocation of gut microbiota/products. Appropriate empirical antibiotics plays a pivotal role in the management of ACLF with infection.

Abstract
Objective: To explore the correlation between the parameters of the new generation of Acoustic Cardiography and brain natriuretic peptide (BNP), left ventricular ejection fraction (LVEF) and cardiac function grading in the diagnosis of heart failure. Methods: One hundred and sixty-eight inpatients, who were hospitalized in Department of Cardiology, Haikou People's Hospital from May 2016 to July 2017, were enrolled as heart failure group, including NYHA class Ⅰ(n=29), NYHA class Ⅱ(n=40), NYHA class Ⅲ(n=64), NYHA class Ⅳ (n=35). And eighty-seven patients with normal cardiac function were selected as healthy control group. The data of the two groups were analyzed after the Acoustic Cardiography test, BNP determination and LVEF examination. Results: The differences in QRS duration, electromechanical activation time (EMAT), EMAT%, systolic dysfunction index (SDI), third heart sound (S3) and other indicators among the groups with different levels of cardiac function were statistically significant (P<0.05). The difference in left ventricular systolic time (LVST) between the cardiac function grade Ⅰ and healthy group was not significant (P>0.05), while the differences among the rest groups were significant. There was a positive correlation between QRS duration, EMAT%, SDI, S3 and BNP (t=9.46, 11.38, 12.14, 9.67, respectively, P<0.05); LVST and BNP were negatively correlated (t=-14.27, P<0.05). There was a negative correlation between QRS duration, EMAT%, SDI, S3 and LVEF (t=11.24, -8.764, -2.393, -0.579, respectively, P<0.05). There was a positive correlation between LVST and LVEF (t=23.48, P<0.05). There was a positive correlation between QRS duration, EMAT%, SDI, S3 and cardiac function grading (β=0.003, 0.234, 0.419, 0.352, respectively, P<0.05). There was a negative correlation between LVST and cardiac function grade (β=-0.021, P<0.05). Conclusion: The parameters of the Acoustic Cardiography test (EMAT%, EMAT, SDI, S3 ) are closely related to BNP, LVEF and cardiac function grading, and can be used as assistant indexes for the diagnosis and evaluation of heart failure.

Abstract
Current treatments for hepatitis C include pegylated interferon-α (Peg-IFNα) and ribavirin (RBV) combination therapy and direct antiviral agents (DAAs). Antiviral treatment can be initiated after 4 to 6 months of clinical observations for patients with acute infections, but should be started as early as possible for those with chronic infections. However, for patients who are ineligible for Peg-IFN and RBV combination therapy and have no unrestricted access to DAAs, it is advised that they wait for the approval of DAAs in China if their medical condition is under control. Though, antiviral therapy should be started immediately if the disease progresses. It has been reported that there are numerous clinical benefits of antiviral treatment for hepatitis C. However, the long-term impact of DAAs treatment including efficacy and safety is limited and remains to be explored.

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
Transient elastography (TE) is accurate in staging fibrosis noninvasively. However, a reliable serum biomarker with comparable accuracy is also important, especially when TE is unreliable/unavailable. Therefore, we aimed to evaluate the diagnostic performance of serum Golgi protein 73 (GP73) for significant fibrosis in patients with chronic HBV infection. A total of 801 patients with chronic liver disease (CLD; 492 chronic HBV infection and 309 non-HBV liver disease) with liver biopsy performance were enrolled. Healthy controls (n = 180) and hepatocellular carcinoma (HCC) patients (n = 85) were included for comparisons. Liver biopsy was used as the reference method for fibrosis staging. Serum GP73 level was measured in duplicate in double-blind fashion. Serum GP73 was highest in HCC but also significantly higher in chronic hepatitis B than in healthy controls. The elevation of serum GP73 in non-HCC patients was significantly associated with the presence of significant fibrosis independently of ALT level, liver stiffness (LS) value, inflammation grade and other confounding factors. The diagnostic performance of serum GP73 was accurate in antiviral-naïve HBV patients (area under the receiver operating curve [AUROC], 0.76 95% CI: 0.72-0.81) but not in patients with ongoing antiviral treatment (AUROC, 0.60). The utility of serum GP73 was also confirmed in non-HBV CLD (AUROC, 0.80 95% CI: 0.75-0.85). Serum GP73 was comparable to LS (AUROC, 0.78 95% CI: 0.73-0.82) and significantly better than AST to platelet ratio index (APRI) (AUROC, 0.67 95% CI: 0.62-0.72) and FIB-4 (AUROC, 0.68 95% CI: 0.63-0.73). In conclusion, serum GP73 is an accurate serum marker for significant fibrosis in chronic HBV infection, with higher accuracy than APRI and FIB-4. Serum GP73 is potentially a complementary tool for TE when evaluating the necessity of antiviral treatment, particularly in patients without definite antiviral indication.

Abstract
Reports on the efficacy and safety of long-term entecavir treatment in chronic hepatitis B (CHB) predominantly genotype B or C are insufficient. This study presents the efficacy and safety of entecavir maleate in Chinese CHB patients. Patients were randomly assigned to receive 48-week treatment with either 0.5 mg/day entecavir (group A) or 0.5 mg/day entecavir maleate (group B), and then all patients received treatment with 0.5 mg/day entecavir maleate from week 49. Two hundred and seventy-five patients with CHB (HBeAg-positive: 218) were analysed, predominantly (98.5%) with genotype B or C. Baseline characteristics were balanced. For the HBeAg-positive CHB patients, the mean HBV DNA level decreased similarly (A: by 6.36 log10 IU/mL vs B: by 6.31 log10 IU/mL) between groups at week 144. The percentages of patients who achieved undetectable HBV DNA were similar (A: 70.59% vs B: 66.67%) between groups. Similar HBeAg loss rates (A: 43.53% vs B: 40.23%; P>.05) and HBeAg seroconversion rates (A: 21.52% vs B: 21.18%) were achieved. For the HBeAg-negative CHB patients, similar reductions in HBV DNA levels from baseline (A: by 6.13 log10 IU/mL vs B: by 5.65 log10 IU/mL) and percentages of patients who achieved undetectable HBV DNA (A: 100% vs B: 100%) were achieved. The overall incidence of adverse events was comparable between groups. In conclusions, 48-week administration of entecavir maleate and entecavir showed similar efficacy and safety in Chinese patients with CHB. Long-term entecavir maleate treatment was effective and safe in CHB patients.

Abstract
AIM To investigate and compare the effects of two apical canal instrumentation protocols on apical stress distribution at the root apex under vertical compaction of gutta-percha and occlusal loads using finite element analysis. METHODOLOGY Three finite element analysis models of a mandibular first premolar were reconstructed: an original canal model, a size 35, .04 taper apical canal enlargement model and a Lightspeed size 60 apical canal enlargement model. A 15 N compaction force was applied vertically to the gutta-percha 5 mm from the apex. A 175 N occlusal load in two directions (vertical and 45° to the longitudinal axis of the tooth) was simulated. Stresses in the apical 2 mm of the root were calculated and compared among the three models. RESULTS Under vertical compaction, stresses in the apical canal instrumented by Lightspeed size 60 (maximal 3.3 MPa) were higher than that of the size 35, .04 taper model (maximal 1.3 MPa). In the case of the two occlusal forces, the Lightspeed size 60 apical enlargement was associated with the greatest stress distribution in the apical region. The greatest stress and the most obvious stress difference between the models appeared at the tip of the root when occlusal and vertical compaction loads were applied. CONCLUSIONS Apical enlargement caused stress distribution changes in the apical region of roots. The larger apical size led to higher stress concentration at the root apex.

Abstract
Chronic hepatitis B infection (CHB) causes up to 1.0 million deaths annually. Currently, more than 90% of CHB patients worldwide are receiving indefinite nucleos(t)ide analogue (NA) therapy. New strategies for optimizing hepatitis B surface antigen (HBsAg) loss are required for NA-treated patients as the majority are unable to achieve HBsAg loss and may require lifelong therapy. In hepatitis B e antigen (HBeAg)-positive patients, switching from NAs to finite peginterferon (PegIFN) therapy can double HBeAg seroconversion rates. One in five patients who switch to PegIFN can achieve HBsAg loss, whereas patients who continue NA therapy typically do not. In HBeAg-negative NA-treated patients, add-on PegIFN therapy achieves higher, albeit modest, HBsAg loss rates compared with continued NA monotherapy and offers the opportunity for NA-treated patients to achieve the inactive carrier state. In the absence of curative therapies, PegIFN represents a valuable, finite option for NA-treated patients who would otherwise require potentially lifelong therapy.

Abstract
Studies regarding the clinical significance of quantitative hepatitis B core antibody (anti-HBc) in patients with chronic hepatitis B receiving first-line nucleos(t)ide analogues is limited. The aim of this study was to determine the performance of anti-HBc as a predictor for hepatitis B e antigen (HBeAg) seroconversion in HBeAg-positive CHB patients treated with entecavir. This was a retrospective cohort study consisting of 139 Chinese patients enrolled in a multicenter clinical trial treated with entecavir or entecavir maleate for up to 240 weeks. Anti-HBc evaluation was conducted for all the available samples using a newly developed double-sandwich anti-HBc immunoassay. At week 240, 35 (25.2%) patients achieved a serological response (HBeAg seroconversion) and these patients at week 240 had significantly higher levels of anti-HBc (P<.01). We defined 4.65 log10 IU·mL-1 , with a maximum sum of sensitivity and specificity, as the optimal cut-off value of baseline anti-HBc level to predict seroconversion. Patients with baseline anti-HBc ≥4.65 log10 IU·mL-1 had 28.0% (26/93) and 35.5% (33/93) chance of seroconversion at weeks 144 and 240, respectively. The baseline anti-HBc level was the strongest predictor for seroconversion at week 144 (OR: 5.78, 95% confidence interval [CI]: 2.05-16.34, P=.001). The baseline anti-HBc level was a strong predictor for seroconversion at week 240 (OR: 5.36, 95% CI: 2.17-13.25, P<.001). Hence, baseline anti-HBc titre is a useful predictor of long-term entecavir therapy efficacy in HBeAg-positive CHB patients, which could be used to optimize antiviral therapy.

Abstract
OBJECTIVES To explore the species distribution and constituent ratio of diatoms in main sections of urban district rivers where drowning occurs frequently in Chengdu. METHODS Total 39 water samples from the sampling points of 5 rivers (Jinjiang, Jinniu, Qingyang, Wuhou and Chenghua districts) in October 2014 were collected. The diatoms smear were made and the species distribution and constituent ratio of diatoms from the water samples were analyzed using biological microscope and acquisition system of digital microscope. RESULTS Total 21 species of diatoms were detected in main sections of urban district rivers in Chengdu. Significant differences in the dominant diatom species and proportions of the different rivers were observed, and there were different species existed in all sampling points of the upstream, midstream and downstream of the rivers. CONCLUSIONS The database of species map, species distribution and constituent ratio of diatoms in main sections of urban district rivers in Chengdu are preliminarily established, which has special meaning for the analysis and evaluation of falling location inference using diatoms test in case investigation.

Abstract
Duck Tembusu virus (DTMUV) is an infectious pathogen that can cause epidemics in egg-laying ducks. Here, we isolated and characterized a DTMUV, designated GDLH01, thought to be responsible for the noticeable egg drop in Muscovy duck flocks in South China since 2011. The genome sequence of GDLH01 shared 97-99% homology with other avian-origin Tembusu viruses, and 99.5% homology with the mosquito-borne strain SDMS recently reported in China. Phylogenetic analysis based on the nucleotide sequence of the entire open reading frame confirmed that the isolate was of avian origin and closely related to a mosquito-borne strain. Our findings characterize a novel Tembusu virus circulating in Muscovy ducks in South China and emphasize the importance of reinforcing biosecurity measures and developing vaccines to prevent the spread of this viral pathogen.

Abstract
It is unknown whether peginterferon (PEG-IFN) add-on to entecavir (ETV) leads to more HBsAg decline compared to PEG-IFN monotherapy or combination therapy, and whether ETV therapy may prevent HBsAg increase after PEG-IFN cessation. We performed a post hoc analysis of 396 HBeAg-positive patients treated for 72 weeks with ETV + 24 weeks PEG-IFN add-on from week 24 to 48 (add-on, n = 85), 72 weeks with ETV monotherapy (n = 90), 52 weeks with PEG-IFN monotherapy (n = 111) and 52 weeks PEG-IFN + lamivudine (combination, n = 110) within 2 randomized trials. HBsAg decline was assessed at the end of PEG-IFN (EOP) and 6 months after PEG-IFN (EOF) discontinuation. Differences in baseline characteristics were accounted for using inversed probability of treatment weights. At EOP, a HBsAg reduction of ≥1log10 IU/mL was more frequently achieved for patients in the add-on or combination therapy arms (both 36%), compared to PEG-IFN mono (20%) or ETV (8%) (add-on vs PEG-IFN mono P = 0.050). At EOF, the HBsAg reduction ≥1log10 IU/mL was only sustained in patients treated with ETV consolidation (add-on vs combination and PEG-IFN mono: 40% vs 23% and 18%, P = 0.029 and P = 0.003, respectively). For add-on, combination, PEG-IFN mono and ETV, the mean HBsAg-level change at EOF was -0.84, -0.81, -0.68 and -0.33 log10 IU/mL, respectively (P > 0.05 for PEG-IFN arms). HBeAg loss at EOF was 36%, 31%, 33% and 20%, respectively (P > 0.05). PEG-IFN add-on for 24 weeks results in more on-treatment HBsAg decline than does 52 weeks of PEG-IFN monotherapy. ETV therapy may maintain the HBsAg reduction achieved with PEG-IFN.

Abstract
To ward off a wide variety of pathogens, the human adaptive immune system harbors a vast array of T-cell receptors (TCRs) and B-cell receptors (BCRs), collectively referred to as the immune repertoire. High-throughput sequencing (HTS) of TCR/BCR genes allows in-depth molecular analysis of T/B-cell clones, providing an unprecedented level of detail when examining the T/B-cell repertoire of individuals. It can evaluate TCR/BCR complementarity-determining region 3 (CDR3) diversity and assess the clonal composition, including the size of the repertoire; similarities between repertoires; V(D)J segment use; nucleotide insertions and deletions; CDR3 lengths; and amino acid distributions along the CDR3s at sequence-level resolution. Deep sequencing of B-cell and T-cell repertoires offers the potential for a quantitative understanding of the adaptive immune system in healthy and disease states. Recently, paired sequencing strategies have also been developed, which can provide information about the identity of immune receptor pairs encoded by individual T or B lymphocytes. HTS technology provides a previously unimaginable amount of sequence data, accompanied, however, by numerous challenges associated with error correction and interpretation that remain to be solved. The review details some of the technologies and some of the recent achievements in this field.

Abstract
OBJECTIVE To observe the efficacy and safety of bivalirudin use in Chinese patients with coronary heart disease (CHD) during the peri-percutaneous coronary intervention(PCI) period. METHODS A total of 3 271 patients who underwent PCI and received periprocedural bivalirudin treatment between July 2013 and October 2015 from 88 centers of China were involved in this study. The primary outcome was 30-day net adverse clinical events (NACE a composite of major adverse cardiac or cerebral events (MACE, all-cause death, reinfarction, urgent target vessel revascularization, or stroke) or bleeding), the secondary outcome was stent thrombosis at 30 days. RESULTS The mean age of enrolled patients was (65.12±12.44) years old, 27.4%(889/3 244) of them were female. Percent of stable coronary disease (SCD), non-ST segment elevation acute coronary syndrome (NSTE-ACS) and ST elevation myocardial infarction (STEMI) was 5.0%(162/3 248), 44.6%(1 450/3 248) and 50.4%(1 636/3 248) respectively. Radial access was performed in 89.5% (2 879/3 271) patients, and 9.7% (316/3 271) and 34.1% (1 115/3 271) patients also received ticagrelor and tirofiban medication. 69.3% (2 266/3 271) patients received post-procedural bivalirudin infusion, in which 46.3% (1 050/2 266) was treated at PCI-does, with a median duration of 2.5(1.0, 4.0) h. During the 30-day follow-up, NACE occurred in 3.45% (103/2 988) patients, the incidence of MACE, death was 2.17% (65/2 994) and 1.03% (31/3 017), respectively and bleeding events were recorded in 1.37% (41/2 996) patients. Four cases (0.13%) of stent thrombosis (3 acute stent thrombosis) were recorded. CONCLUSION Peri-PCI Bivalirudin use is safe and related with low bleeding risk in Chinese CHD patients.

Abstract
Hepatitis B core-related antigen (HBcrAg), a new serum marker, may be useful in monitoring chronic hepatitis B infection. HBcrAg was measured in 175 hepatitis B e antigen-positive patients treated with entecavir (ETV) with or without peginterferon (PEG-IFN) add-on therapy. Decline in HBcrAg was stronger in patients with vs. without combined response (ETV: -3.22 vs. -1.71 log U/mL, p <0.001; PEG-IFN add-on: -3.16 vs. -1.83 IU/mL, p <0.001) and in patients with vs. without hepatitis B surface antigen (HBsAg) response (ETV: -2.60 vs. -1.74 log U/mL, p <0.001; PEG-IFN add-on: -2.38 vs. -2.15 log U/mL, p = 0.31). HBcrAg was associated with combined response (adjusted odds ratio 0.3, 95% confidence interval 0.2-0.5, p <0.001), but was not superior to quantitative HBsAg (qHBsAg).

Abstract
AIMS To screen and identify safe micro-organisms used during Douchi fermentation, and verify the feasibility of producing high-quality Douchi using these identified micro-organisms. METHODS AND RESULTS PCR-denaturing gradient gel electrophoresis (DGGE) and automatic amino-acid analyser were used to investigate the microbial diversity and free amino acids (FAAs) content of 10 commercial Douchi samples. The correlations between microbial communities and FAAs were analysed by statistical analysis. Ten strains with significant positive correlation were identified. Then an experiment on Douchi fermentation by identified strains was carried out, and the nutritional composition in Douchi was analysed. Results showed that FAAs and relative content of isoflavone aglycones in verification Douchi samples were generally higher than those in commercial Douchi samples. CONCLUSIONS Our study indicated that fungi, yeasts, Bacillus and lactic acid bacteria were the key players in Douchi fermentation, and with identified probiotic micro-organisms participating in fermentation, a higher quality Douchi product was produced. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report to analyse and confirm the key micro-organisms during Douchi fermentation by statistical analysis. This work proves fermentation micro-organisms to be the key influencing factor of Douchi quality, and demonstrates the feasibility of fermenting Douchi using identified starter micro-organisms.

Abstract
The objective of this study was to evaluate the effects of different levels of flavones of sea buckthorn fruits (FSBF) on growth performance, carcass quality, fat deposition, and lipometabolism for broilers. 240 one-day-old Arbor Acres male broilers were randomly allotted to 4 dietary treatments (0, 0.05%, 0.10%, and 0.15% FSBF) with 6 replicates of 10 birds. Broilers were reared for 42 d. Results showed FSBF quadratically improved average daily feed intake (ADFI), average daily gain (ADG), and final body weight (BW) (P = 0.002, P = 0.019 and P = 0.018, respectively). The abdominal fat percentage in 0.05%, 0.10%, and 0.15% FSBF supplementation groups was decreased by 21.08%, 19.12%, and 19.61% with respect to the control group, respectively (P < 0.05). The intramuscular fat (IMF) content in the breast muscle of the broilers was increased by 7.21%, 23.42% and 6.30% in 0.05%, 0.10% and 0.15% FSBF groups, and that in the thigh meat was raised by 4.43%, 24.63% and 12.32%, compared with the control group, respectively (P < 0.05). FSBF had a quadratic effect on the abdominal fat percentage and IMF in the breast muscle (P < 0.05). Dietary FSBF also modified fatty acids of muscular tissues, resulting in a higher ratio of unsaturated to saturated fatty acids (P < 0.05). Supplementing FSBF in the diet greatly decreased the levels of triglyceride, cholesterol, and low-density lipoprotein cholesterol (P < 0.05). Moreover, the quadratic responses were also observed in the levels of insulin and adiponectin in serum (P = 0.020 and P = 0.037, respectively). Abdominal fat percentage was correlated negatively with insulin and positively with adiponectin (P < 0.05). IMF content in the breast and thigh muscles were correlated positively with insulin, and negatively with adiponectin (P < 0.05). A positive correlation existed between breast muscle, IMF, and leptin (P < 0.05). In conclusion, adding FSBF into the diets affected growth performance and fat deposition of broilers by regulating lipometabolism. Fat deposition and distribution of broilers were closely associated with concentrations of insulin and adiponectin. The optimal level of FSBF supplemented in diet was 0.05 to 0.10% in this study.

Abstract
Gαq, the alpha subunit of Gq, a member of the Gq/11 sub-family, was reported to inhibit phosphatidylinositol-3-Kinase (PI3K) activation and prevent the activation of Akt. Previous studies demonstrated that mice losing Gαq in their immune system could spontaneously develop inflammatory arthritis. In this study, we showed that the Gαq expressions at mRNA and protein levels in the peripheral blood lymphocytes (PBLs) from patients with rheumatoid arthritis (RA) were significantly decreased in comparison of which in healthy individuals. The expression levels of Gαq mRNA in PBLs from patients with RA were correlated with RA disease activity (DAS28), anti-cyclic citrullinated protein antibodies, C-reactive protein and rheumatoid factor. We also demonstrated that Gαq controlled the apoptosis of RA PBLs through regulating the activity of Mcl-1 and caspase-3. These data suggested that Gαq might be involved in the pathogenesis of RA by regulating PBLs apoptosis.

Abstract
Calcineurin inhibitor cyclosporine is widely used as an immunosuppressant in clinic. However, mounting evidence has shown that cyclosporine hinders tolerance induction by dampening Tregs. Therefore, it is of paramount importance to overcome this pitfall. Kaempferol was reported to inhibit DC function. Here, we found that kaempferol delayed islet allograft rejection. Combination of kaempferol and low-dose, but not high-dose, of cyclosporine induced allograft tolerance in majority of recipient mice. Although kaempferol plus either dose of cyclosporine largely abrogated proliferation of graft-infiltrating T cells and their CTL activity, both proliferation and CTL activity in mice treated with kaempferol plus low-dose, but not high-dose, cyclosporine reemerged rapidly upon treatment withdrawal. Kaempferol increased CD4+FoxP3+ Tregs both in transplanted mice and in vitro, likely by suppressing DC maturation and their IL-6 expression. Reduction in Tregs by low dose of cyclosporine was reversed by kaempferol. Kaempferol-induced Tregs exhibited both allospecific and non-allospecific suppression. Administering IL-6 abrogated allograft tolerance induced by kaempferol and cyclosporine via diminishing CD4+FoxP3+ Tregs. Thus, for the first time, we demonstrated that kaempferol promotes transplant tolerance in the presence of low dose of cyclosporine, which allows for sufficient Treg generation while minimizing side effects, resulting in much-needed synergy between kaempferol and cyclosporine.

Abstract
Sex-determining region Y box 6 (SOX6) has been described as a tumor-suppressor gene in several cancers. Our previous work has suggested that SOX6 upregulated p21Waf1/Cip1(p21) expression in a p53-dependent manner; however, the underlying mechanism has remained elusive. In this study, we confirmed that SOX6 can suppress cell proliferation in vitro and in vivo by stabilizing p53 protein and subsequently upregulating p21. Co-immunoprecipitation and immunocytofluorescence assays demonstrated that SOX6 can promote formation of the p14ARF-HDM2-p53 ternary complex by promoting translocation of p14ARF (p14 alternate reading frame tumor suppressor) to the nucleoplasm, thereby inhibiting HDM2-mediated p53 nuclear export and degradation. Chromatin immunoprecipitation combined with PCR assay proved that SOX6 can bind to a potential binding site in the regulatory region of the c-Myc gene. Furthermore, we confirmed that SOX6 can downregulate the expression of c-Myc, as well as its direct target gene nucleophosmin 1 (NPM1), and that the SOX6-induced downregulation of NPM1 is linked to translocation of p14ARF to the nucleoplasm. Finally, we showed that the highly conserved high-mobility group (HMG) domain of SOX6 is required for SOX6-mediated p53 stabilization and tumor inhibitory activity. Collectively, these results reveal a new mechanism of SOX6-mediated tumor suppression involving p21 upregulation via the p14ARF-HDM2-p53 axis in an HMG domain-dependent manner.

Abstract
The taxonomic status of Pinus henryi, a rare species endemic to China, is still ambiguous. In this study, the genetic relationships among P. henryi and its congeners (P. tabulaeformis, P. tabulaeformis var. mukdensis, and P. massoniana) were revealed using multiplexed microsatellite markers, including chloroplast microsatellites, nuclear microsatellites, and expressed sequence tag microsatellites. The results refute the hypothesis that P. henryi is a subspecies of P. tabulaeformis or P. massoniana and support the suggestion that it may be a distinct species closely related to P. tabulaeformis.

Abstract
Pinus tabulaeformis f. shekanensis is a rare taxon endemic in the Ziwuling Loess Plateau, of which only one population is known. Inter-simple sequence repeat molecular markers were employed to compare the taxon's genetic diversity with its 4 nearest wild relatives (P. tabulaeformis, P. tabulaeformis var. mukdensis, P. massoniana, and P. henryi) to assess the taxonomic status of P. tabulaeformis f. shekanensis. Inter-simple sequence repeat marker data revealed higher genetic diversity in the P. tabulaeformis f. shekanensis population than in the other populations. Population genetic analysis (neighbor-joining cluster analysis, principal coordinate analysis, and structure clustering) revealed that P. tabulaeformis f. shekanensis and P. tabulaeformis are likely conspecific (the former may be a variety of the latter). Strategies are also proposed for the conservation of P. tabulaeformis f. shekanensis.

Abstract
Tenofovir disoproxil fumarate (TDF) has demonstrated long-term efficacy and a high barrier to resistance in multiple chronic hepatitis B (CHB) populations outside of China. This study aimed to evaluate the efficacy and safety of TDF compared with adefovir dipivoxil (ADV) in Chinese patients with CHB during 48 weeks of treatment (ClinicalTrial.gov number, NCT01300234). A Phase 3, multicentred, randomized, double-blind, controlled trial compared the efficacy and safety of TDF with ADV in Chinese patients with CHB. The primary endpoint was the proportion of patients with HBV DNA <400 copies/mL in each treatment group at Week 48, using an unpooled Z-test for superiority. Secondary endpoints included viral suppression, serologic response, histological improvement, normalization of alanine aminotransferase (ALT) levels and the emergence of resistance mutations. A total of 509 patients, 202 hepatitis B e antigen (HBeAg)-positive and 307 HBeAg-negative, with HBV DNA ≥10(5) copies/mL received either TDF 300 mg od or ADV 10 mg od. At Week 48, TDF demonstrated superior viral suppression compared with ADV in both HBeAg-positive (76.7% vs 18.2%, P < 0.0001) and HBeAg-negative (96.8% vs 71.2%, P < 0.0001) patients. The majority of patients in both treatment arms achieved ALT normalization (>85%). No resistance to TDF was observed. The frequency of adverse events was comparable between treatment arms (TDF 3.9% vs ADV 4.8%). In this double-blind, randomized, clinical trial, TDF demonstrated superiority over ADV with respect to viral suppression in Chinese patients with CHB at 48 weeks of treatment and without the development of resistance.

Abstract
BACKGROUND The use of extra-levator abdominoperineal resection (ELAPE) procedure for lower rectal cancer is controversial. It is unclear whether the ELAPE procedure could improve surgical safety and lead to better oncological outcomes. METHODS Sixty-nine lower rectal cancer patients who underwent ELAPE (36 cases) or conventional abdominoperineal resection (APE; 33 cases) between June 2011 and February 2013 were prospectively investigated. Clinicopathological variables including blood loss, intraoperative perforation (IOP) rate, circumferential resection margin (CRM) involvement, lymph node harvest, the postoperative complications, urinary and sexual function, quality of life (QOL), local recurrence rate and survival were recorded and compared. RESULTS Blood loss (P = 0.021), perineal wound complication (P = 0.039), IOP rate (P = 0.028), local recurrence (P = 0.034) were significantly less frequent in the ELAPE group. There was greater CRM involvement in the conventional APE group but no statistical difference between the two groups. Urinary function, sexual function and QOL were not significantly different between the two groups. Overall survival and progression-free survival were not significantly different between two groups, even when survival was analyzed according to TNM stage, T stage, N stage, and with or without neoadjuvant chemoradiotherapy. In patients who underwent ELAPE there was no statistical difference in postoperative complications between younger and elderly patients (age ≥60). CONCLUSIONS ELAPE procedure with definitive anatomic landmarks demonstrated surgical safety and decreased local recurrence for lower rectal cancer patients including the elderly, but there were no survival improvements in compared to conventional APE procedure.

Abstract
PURPOSE Transcription factor 21 (TCF21) has been identified as a candidate tumor suppressor at 6q23-q24 that is epigenetically inactivated in many types of human cancers. This study aimed to determine the expression of TCF21 mRNA and protein in gastric cancer cell lines and tissue specimens and then investigate the prognostic impact of TCF21 expression in gastric cancer and analyze the relationship between TCF21 expression and methylation level. METHODS We used real-time PCR and immunohistochemical staining to detect the expression of TCF21 and used methylation-specific-PCR to determine the methylation status of TCF21 in gastric cancer samples and gastric cancer cell lines. RESULTS The results showed that TCF21 expression level in gastric cancer samples was significantly lower than in normal adjacent tissue samples. The Kaplan-Meier survival analysis demonstrated that TCF21 was a significant prognosticator of cancer-specific survival (p = 0.001). Furthermore, the methylation level of TCF21 in gastric cancer samples was much higher than the samples in normal adjacent tissue. Treatment with the DNA methyltransferase inhibitor 5-Aza-2'-deoxy-cytidine can upregulate the expression of TCF21 in gastric cancer cells. CONCLUSIONS These results suggest that the low expression of TCF21 was an independent prognostic factor for poor survival in patients with gastric cancer. Aberrant methylation was an important reason for the downregulation of TCF21 and may be associated with tumorigenesis in gastric cancer.
