Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a malignant tumor with poor prognosis and high mortality. Although a large number of studies have explored its potential prognostic markers using traditional RNA sequencing (RNA-Seq) data, they have not achieved good prediction effect. In order to explore the possible prognostic signaling pathways leading to the difference in prognosis, we identified differentially expressed genes from one scRNA-seq cohort and four GEO cohorts, respectively. Then Cox and Lasso regression analysis showed that 12 genes were independent prognostic factors for PDAC. AUC and calibration curve analysis showed that the prognostic model had good discrimination and calibration. Compared with the low-risk group, the high-risk group had a higher proportion of gene mutations than the low-risk group. Immune infiltration analysis revealed differences in macrophages and monocytes between the two groups. Prognosis related genes were mainly distributed in fibroblasts, macrophages and type 2 ducts. The results of cell communication analysis showed that there was a strong communication between cancer-associated fibroblasts (CAF) and type 2 ductal cells, and collagen formation was the main interaction pathway.

Abstract
Multi-regional clinical trial (MRCT) has become an increasing trend for its supporting simultaneous global drug development. After MRCT, consistency assessment needs to be conducted to evaluate regional efficacy. The weighted Z-test approach is a common consistency assessment approach in which the weighting parameter W does not have a good practical significance; the discounting factor approach improved from the weighted Z-test approach by converting the estimation of W in original weighted Z-test approach to the estimation of discounting factor D. However, the discounting factor approach is an approach of frequency statistics, in which D was fixed as a certain value; the variation of D was not considered, which may lead to un-reasonable results. In this paper, we proposed a Bayesian approach based on D to evaluate the treatment effect for the target region in MRCT, in which the variation of D was considered. Specifically, we first took D random instead of fixed as a certain value and specified a beta distribution for it. According to the results of simulation, we further adjusted the Bayesian approach. The application of the proposed approach was illustrated by Markov Chain Monte Carlo simulation.

Abstract
BACKGROUND Patients treated with drug-coated balloons (DCB) have the theoretical advantage of adopting a low-intensity antiplatelet regimen due to the absence of struts and polymers. Nevertheless, the optimal antiplatelet strategy for patients undergoing DCB-only treatment remains a topic of debate and has not been investigated in randomized trials. METHODS The REC-CAGEFREE II is an investigator-initiated, prospective, open-label, multi-center, randomized, non-inferiority trial aimed to enroll 1908 patients from ≥ 40 interventional cardiology centers in China to evaluate the non-inferiority of an antiplatelet regimen consisting of Aspirin plus Ticagrelor for one month, followed by five months Ticagrelor monotherapy, and then Aspirin monotherapy for six months (Experimental group) compared to the conventional treatment of Aspirin plus Ticagrelor for 12 months (Reference group) in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) using paclitaxel-coated balloons (DCB) exclusively. Participants will be randomly assigned to the Experimental or Reference group in a 1:1 ratio. The randomization will be stratified based on the center and the type of lesion being treated (De novo or in-stent restenosis). The primary endpoint is net adverse clinical events (NACE) within 12 months of PCI, which includes the composite of all-cause death, any stroke, any myocardial infarction, any revascularization and Bleeding Academic Research Consortium (BARC) defined type 3 or 5 bleeding. The secondary endpoint, any ischemic and bleeding event, which includes all-cause death, any stroke, MI, BARC-defined type 3 bleeding, any revascularization, and BARC-defined type 2 bleeding events, will be treated as having hierarchical clinical importance in the above order and analyzed using the win ratio method. DISCUSSION The ongoing REC-CAGEFREE II trial aims to assess the efficacy and safety of a low-intensity antiplatelet approach among ACS patients with DCB. If non-inferiority is shown, the novel antiplatelet approach could provide an alternative treatment for ACS patients with DCB. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT04971356.

Abstract
BACKGROUND Myasthenia gravis (MG) is an autoimmune disease that affects neuromuscular junction. The literature suggests the involvement of circulating cytokines (CK), gut microbiota (GM), and serum metabolites (SM) with MG. However, this research is limited to observational trials, and comprehensive causal relationship studies have not been conducted. Based on published datasets, this investigation employed Mendelian Randomization (MR) to analyze the known and suspected risk factors and biomarkers causal association of MG and its subtypes. METHODS This research used two-sample MR and linkage disequilibrium score (LDSC) regression of multiple datasets to aggregate datasets acquired from the genome-wide association studies (GWAS) to assess the association of MG with 41-CK, 221-GM, and 486-SM. For sensitivity analysis and to validate the robustness of the acquired data, six methods were utilized, including MR-Egger regression, inverse variance weighting (IVW), weighted median, and MR-PRESSO. RESULTS The MR method identified 20 factors significantly associated with MG, including 2 CKs, 6 GMs, and 9 SMs. Further analysis of the factors related to the two MG subtypes, early-onset MG (EOMG) and late-onset MG (LOMG), showed that EOMG had a high overlap with MG in the intestinal flora, while LOMG had a greater similarity in CKs and SMs. Furthermore, LDSC regression analysis indicated that Peptococcaceae, oxidized biliverdin, and Kynurenine had significant genetic correlations with general MG, whereas EOMG was highly correlated with Intestinibacter, while LOMG had significant genetic associations with Kynurenine and Glucose. CONCLUSION This research furnishes evidence for the potential causal associations of various risk factors with MG and indicates a heterogeneous relationship between CKs, GMs, and SMs with MG subtypes.

Abstract
BACKGROUND AND AIMS Large spontaneous portosystemic shunt (SPSS) is associated with increased risk of HE in patients undergoing transjugular intrahepatic portosystemic shunt (TIPS). This study aimed to evaluate whether prophylactic embolization of large SPSS at the time of TIPS creation could reduce the incidence of post-TIPS HE in patients with cirrhosis and variceal bleeding. APPROACH AND RESULTS From June 2014 to August 2017, 56 patients with cirrhosis and large SPSS planning to undergo TIPS for the prevention of variceal bleeding were randomly assigned (1:1) to receive TIPS alone (TIPS group, n = 29) or TIPS plus simultaneous SPSS embolization (TIPS+E group, n = 27). The primary endpoint was overt HE. TIPS placement and SPSS embolization was successful in all patients. During a median follow-up of 24 months, the primary endpoint was met in 15 patients (51.7%) in the TIPS group and six patients (22.2%) in the TIPS+E group (p = 0.045). The 2-year cumulative incidence of overt HE was significantly lower in the TIPS+E group compared with the TIPS group (21.2% vs. 48.3%; HR, 0.38; 95% CI, 0.15-0.97; p = 0.043). The 2-year incidence of recurrent bleeding (TIPS+E vs. TIPS, 15.4% vs. 25.1%; p = 0.522), shunt dysfunction (12.3% vs. 18.6%, p = 0.593), death (15.0% vs. 6.9%, p = 0.352), and other adverse events was not significantly different between the two groups. CONCLUSIONS In patients with cirrhosis treated with TIPS for variceal bleeding, concurrent large SPSS embolization reduced the risk for overt HE without increasing other complications. Concurrent large SPSS embolization should therefore be considered for prophylaxis of post-TIPS HE.

Abstract
BACKGROUND The role of variceal embolisation at the time of transjugular intrahepatic portosystemic shunt (TIPS) creation for the prevention of gastro-oesophageal variceal rebleeding remains controversial. This study aimed to evaluate whether adding variceal embolisation to TIPS placement could reduce the incidence of rebleeding after TIPS in patients with cirrhosis. METHODS We did an open-label, randomised controlled trial at one university hospital in China. Eligible patients were aged 18-75 years with cirrhosis and had variceal bleeding in the past 6 weeks, and they were randomly assigned (1:1) to receive TIPS (with a covered stent in both groups) plus variceal embolisation (TIPS plus embolisation group) or TIPS alone (TIPS group) to prevent variceal rebleeding. Randomisation was done using a web-based randomisation system using a Pocock and Simon's minimisation method, stratified by Child-Pugh class (A vs B vs C). Clinicians and patients were not masked to treatment allocation; individuals involved in data analysis were masked to treatment assignment. The primary endpoint was the 2-year cumulative incidence of variceal rebleeding after randomisation, and analysis was by intention to treat. The trial is registered with ClinicalTrials.gov, NCT02119988. FINDINGS Between June 16, 2014, and Feb 3, 2016, 205 patients were screened, of whom 134 were randomly allocated to the TIPS plus embolisation group (n=69) and the TIPS group (n=65). TIPS placement and variceal embolisation was successful in all 134 patients, all were included in the analysis. There was no significant difference in the 2-year cumulative incidence of variceal rebleeding between the two groups (TIPS plus embolisation 11·6% [95% CI 4·0-19·1] vs TIPS 13·8% [5·4-22·2]; hazard ratio 0·82 [95% CI 0·42-1·61]; p=0·566). Adverse events were similar between the two groups; the most common adverse events were peptic ulcer or gastritis (12 [17%] of patients in the TIPS plus embolisation group vs 13 [20%] of patients in the TIPS group), new or worsening ascites (ten [14%] vs six [9%]), and hepatocellular carcinoma (four [6%] vs six [9%]). The numbers of deaths were also similar between groups (24 [35%] vs 25 [38%]) INTERPRETATION: Adding variceal embolisation to TIPS did not significantly reduce the incidence of variceal rebleeding in patients with cirrhosis. Our findings do not support concomitant variceal embolisation during TIPS for the prevention of variceal rebleeding.

Background To determine the non-inferiority of the seven common serotypes (4, 6B, 9V, 14, 18C, 19F, and 23F) in the 13-valent pneumococcal conjugate vaccine (PCV13) with each serotype conjugated to a tetanus toxoid carrier protein and adsorbed on aluminum phosphate and the superiority of its six additional serotypes (1, 3, 5, 6A, 7F, and 19A) to the serotypes in the PCV7. Methods Participants were evenly randomized in a 1:1 ratio into either the PCV13 or PCV7 groups, to receive three doses of the vaccine at the age of 3, 4, and 5 months, respectively, and a booster dose between 12 and 15 months of age. Serotype-specific antibodies were measured using a standardized enzyme-linked immunosorbent assay (ELISA) and opsonophagocytic activity (OPA) microcolony assay method. Results A total of 1,040 healthy infants were enrolled. All the seven common serotypes in the PCV13 were non-inferior to those in the PCV7 in terms of the serotype-specific IgG production induced; however, non-inferiority was not shown for serotype 6B after the infant series. The proportion of subjects who reached OPA antibody titers ≥ 1:8 in the PCV13 group was 89.25% or higher. Local reactions and systemic events were mild or moderate in severity and similar between the two groups. No new safety signals were observed. Conclusion The newly developed PCV13 was immunogenic for all serotypes and had a comparable safety profile to the marketed PCV7.

Abstract
OBJECTIVES Objective response rate (ORR) under mRECIST criteria after transarterial chemoembolization (TACE) is a well-perceived surrogate endpoint of overall survival (OS). However, its optimal time point remains controversial and may be influenced by tumor burden. We aim to investigate the surrogacy of initial/best ORR in relation to tumor burden. METHODS A total of 1549 eligible treatment-naïve patients with unresectable hepatocellular carcinoma (HCC), Child-Pugh score ≤ 7, and performance status score ≤ 1 undergoing TACE between January 2010 and May 2016 from 17 academic hospitals were retrospectively analyzed. Based on "six-and-twelve" criteria, tumor burden was graded as low, intermediate, and high if the sum of the maximum tumor diameter and tumor number was ≤ 6, > 6 but ≤ 12, and > 12, respectively. RESULTS Both initial and best ORRs interacted with tumor burden. Initial and best ORRs could equivalently predict and correlate with OS in low (adjusted HR, 2.55 and 2.95, respectively, both p < 0.001; R = 0.84, p = 0.035, and R = 0.97, p = 0.002, respectively) and intermediate strata (adjusted HR, 1.81 and 2.22, respectively, both p < 0.001; R = 0.74, p = 0.023, and R = 0.9, p = 0.002, respectively). For high strata, only best ORR exhibited qualified surrogacy (adjusted HR, 2.61, p < 0.001; R = 0.70, p = 0.035), whereas initial ORR was not significant (adjusted HR, 1.08, p = 0.357; R = 0.22, p = 0.54). CONCLUSIONS ORR as surrogacy of OS is associated with tumor burden. For patients with low/intermediate tumor burden, initial ORR should be preferred in its early availability upon similar sensitivity, whereas for patients with high tumor burden, best ORR has optimal sensitivity. Timing of OR assessment should be tailored according to tumor burden. KEY POINTS • This is the first study utilizing individual patient data to comprehensively analyze the surrogacy of ORR with a long follow-up period. • Optimal timing of ORR assessment for predicting survival should be tailored according to tumor burden. • For patients with low and intermediate tumor burden, initial ORR is optimal for its timeliness upon similar sensitivity with best ORR. For patients with high tumor burden, best ORR has optimal sensitivity.

Abstract
INTRODUCTION Lenvatinib is the first-line treatment for advanced hepatocellular carcinoma (HCC). We aimed to compare the clinical outcomes of lenvatinib plus drug-eluting beads transarterial chemoembolization (DEB-TACE) versus lenvatinib alone in real-world practice. METHODS This retrospective analysis included 142 consecutive patients who received lenvatinib plus DEB-TACE and 69 patients who received lenvatinib alone as first-line treatment from 15 Chinese academic centers from November 2018 to November 2019. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) were evaluated by modified Response Evaluation Criteria in Solid Tumors criteria, and safety profiles were compared between the two groups. RESULTS The median OS and PFS were significantly longer in the combined therapy group than in the monotherapy group in whole cohort (median OS, 15.9 vs. 8.6 months, p = 0.0022; median PFS, 8.6 vs. 4.4 months, p < 0.001) and after propensity score matching analysis (median OS, 13.8 vs. 7.8 months, p = 0.03; median PFS, 7.8 vs. 4.5 months, p = 0.009). Moreover, the treatment option was an independent prognostic factor for OS and PFS with adjustment based upon baseline characteristics (adjusted hazard ratio [HR]: 0.53, 95% confidence interval [CI]: 0.36-0.78, p = 0.001, and adjusted HR: 0.42, 95% CI: 0.30-0.60, p < 0.001, respectively) and propensity score (adjusted HR: 0.52, 95% CI: 0.36-0.76, p = 0.001, and adjusted HR: 0.46, 95% CI: 0.33-0.64, p < 0.001, respectively). Moreover, a greater ORR was observed in the combined group (ORR: 46.48% vs. 13.05%, p < 0.001). Furthermore, the most common adverse events (AEs) were elevated aspartate aminotransferase (54.9%) and fatigue (46.4%) in the lenvatinib plus DEB-TACE group and lenvatinib group, respectively. Most AEs were mild-to-moderate and manageable. CONCLUSIONS With well-tolerated safety, lenvatinib plus DEB-TACE was more effective than lenvatinib monotherapy in improving OS, PFS, and ORR. Thus, it may be a promising treatment for advanced HCC. Future prospective studies confirming these findings are warranted.

Abstract
Objective: To examine the efficacy and safety of endothelin receptor antagonists (ERA) combined with phosphodiesterase 5 inhibitors (PDE5i) in the treatment of pulmonary artery hypertension (PAH). Methods: Computer-based retrieval was performed on PubMed, Cochrane Library, CNKI, Wanfang, and VIP database (up to February 12th, 2021). Randomized controlled trials about endothelin receptor antagonists (ERAs) or PDE5i in patients with PAH were collected. The change of 6-minute walking distance (6MWD) in 12-16 weeks was used as primary outcome index. Case fatality rate, worsening clinical events, WHO functional class (FC) improvement, adverse events (AEs), serious adverse events (SAE) were the key secondary outcomes indicators. STATA 16.0 software was used for network meta-analysis, and the pooled estimates of odds ratios (ORs) or weighted mean differences (WMDs) and 95% confidence intervals (CIs) of the results were shown. To help explain ORs and WMDs, we used the surface under the cumulative ranking curve (SUCRA) to calculate the probability of each intervention. Results: We included 29 trials with 5 949 participants. In network meta-analysis, Bosentan combined with Sildenafil (WMD=53.93, 95%CI=6.19-101.66) had shown the greatest improvement in 6MWD compared with placebo, followed by Bosentan combined with Tadalafil (WMD=50.84, 95%CI=7.05-94.62), Ambrisentan combined with Tadalafil (WMD=46.67, 95%CI=15.88-77.45), Bosentan (WMD=29.44, 95%CI=5.86-53.02), Ambrisentan (WMD=23.90, 95%CI=0.31-47.48) and Macitentan (WMD=21.57, 95%CI=2.45-40.69). According to SUCRA, the effects of different intervention measures on improving 6MWD in patients with arterial pulmonary hypertension were as follows: Bosentan+Sildenafil (82.9%)>Bosentan+Tadalafil (78.4%)>Ambrisentan+Tadalafil (77.1%)>Bosentan (49.2%)>Sildenafil (48.5%)>Ambrisentan (40.3%)>Macitentan (37.3%)>Tadalafil (33.0%)>Placebo (3.3%). For the WHO functional class, Sildenafil (OR=2.90, 95%CI=1.04-8.08) was optimal compared with placebo, followed by Bosentan (OR=2.15, 95%CI=1.15-4.04), and there was no significant difference in the rest. For clinical worsening, Bosentan combined with Tadalafil (OR=0.08, 95%CI=0.01-0.49) performed best compared with placebo, followed by Bosentan (OR=0.20, 95%CI=0.11-0.38), Bosentan combined with Sildenafil (OR=0.21, 95%CI=0.09-0.46), Ambrisentan combined with Tadalafil (OR=0.27, 95%CI=0.15-0.50), Sildenafil (OR=0.33, 95%CI=0.17-0.66) and Tadalafil (OR=0.44, 95%CI=0.21-0.90). There was no statistical difference between all interventions and placebo in terms of the incidence of adverse events and serious adverse events. For case fatality rate, Ambrisentan (OR=0.28, 95%CI=0.11-0.74) was statistically superior to placebo and there was no statistics difference in the rest. Conclusions: The combination therapy of ERAs and PDE5i performed well in the short-term improvement of motor function. Furthermore, there was no significant difference with monotherapy in terms of safety. However, it is worth emphasizing that the choice of treatment should be based on the patient's individualized situation and the patient's requirements.

Abstract
BACKGROUND Ansofaxine (LY03005) extended-release tablet is a potential triple reuptake inhibitor of serotonin, norepinephrine, and dopamine. This study assessed the efficacy, safety, and appropriate dosage of ansofaxine for the treatment of major depressive disorder (MDD). METHODS A multicenter, randomized, double-blind, placebo-controlled, dose-finding, Phase 2 clinical trial was conducted in China. Eligible patients with MDD (18-65 years) were randomly assigned to receive fixed-dose ansofaxine extended-release tablets (40, 80, 120, or 160 mg/d) or placebo for 6 weeks. The primary outcome measure was a change in the total score on the 17-item Hamilton Depression Rating Scale from baseline to week 6. RESULTS A total of 260 patients were recruited from October 2015 to September 2017, and 255 patients received the study drug as follows: 40 mg (n = 52), 80 mg (n = 52), 120 mg (n = 51), and 160 mg (n = 51) ansofaxine and placebo (n = 49). Significant differences were found in mean changes in 17-item Hamilton Depression Rating Scale total scores at week 6 in the 4 ansofaxine groups vs placebo (-12.46; χ2 = -9.71, P = .0447). All doses of ansofaxine were generally well-tolerated. Treatment-related adverse events occurred in 141 patients (303 cases), yielding incidence rates of 51.92%, 65.38%, 56.86%, and 62.75% in the 40-, 80-, 120-, and 160-mg ansofaxine groups and 38.78% in the placebo group. CONCLUSION Active doses (40, 80, 120, and 160 mg/d) of ansofaxine in a controlled setting were safe, tolerated, and effective in improving depression symptoms in MDD patients.

Abstract
Background In follow-up studies, the occurrence of the intermediate event may influence the risk of the outcome of interest. Existing methods estimate the effect of the intermediate event by including a time-varying covariate in the outcome model. However, the insusceptible fraction to the intermediate event in the study population has not been considered in the literature, leading to effect estimation bias due to the inaccurate dataset. Methods In this paper, we propose a new effect estimation method, in which the susceptible subpopulation is identified firstly so that the estimation could be conducted in the right population. Then, the effect is estimated via the extended Cox regression and landmark methods in the identified susceptible subpopulation. For susceptibility identification, patients with observed intermediate event time are classified as susceptible. Based on the mixture cure model fitted the incidence and time of the intermediate event, the susceptibility of the patient with censored intermediate event time is predicted by the residual intermediate event time imputation. The effect estimation performance of the new method was investigated in various scenarios via Monte-Carlo simulations with the performance of existing methods serving as the comparison. The application of the proposed method to mycosis fungoides data has been reported as an example. Results The simulation results show that the estimation bias of the proposed method is smaller than that of the existing methods, especially in the case of a large insusceptible fraction. The results hold for small sample sizes. Besides, the estimation bias of the new method decreases with the increase of the covariates, especially continuous covariates, in the mixture cure model. The heterogeneity of the effect of covariates on the outcome in the insusceptible and susceptible subpopulation, as well as the landmark time, does not affect the estimation performance of the new method. Conclusions Based on the pre-identification of the susceptible, the proposed new method could improve the effect estimation accuracy of the intermediate event on the outcome when there is an insusceptible fraction to the intermediate event in the study population.

Abstract
BACKGROUND Since the declaration of COVID-19 as a global pandemic by the World Health Organization, countries are struggling with a shortage of medical capacities. It would be essential if the risk for preventable comorbidities, such as the common cold, can be reduced or prevented, so that the scarce medical resources and facilities can be focused on COVID-19. PURPOSE To evaluate the effects of two herbal medicines (Jinhaoartemisia antipyretic granules and Huoxiangzhengqi oral liquids) in reducing the risk of the common cold in community-dwelling residents in China during the COVID-19 outbreak. STUDY DESIGN A prospective open-label, parallel-group, cluster-randomized controlled trial (RCT), was conducted in Chengdu, China. METHODS A total of 22,065 participants from 11 communities were recruited during a period of one month. The trial started on 30 January and participants were followed up till 29 February 2020. Participants were randomly assigned to receive either a five-day herbal medicine therapy plus a reference manual or a reference manual only if they were allocated to the control group. The primary endpoint was the occurrence of patient-reported common cold symptoms. The secondary endpoint was the time in days from the receipt of herbal drugs/reference manual and the occurrence of the common cold symptoms. RESULTS Use of herbal medicine reduced the risk of the common cold by 89.6% (95% CI, 52.9% to 97.7%) in all community-dwelling residents, and by 94.0% (95% CI, 52.1% to 99.2%) in residents aged between 16 and 59 years old. Sensitivity analyses showed similar results. CONCLUSION This community-based RCT found that the use of a herbal medicine therapy (Jinhaoartemisia antipyretic granules and Huoxiangzhengqi oral liquids) could significantly reduce the risks of the common cold among community-dwelling residents, suggesting that herbal medicine may be a useful approach for public health intervention to minimize preventable morbidity during COVID-19 outbreak.

Abstract
COVID-19 has become a global pandemic, and an effective vaccine is needed. During the outbreak, the urgency for developing candidate vaccines has brought distinct challenges to clinical development. An efficacy trial, which measures whether the vaccine reduces the incidence of disease, is ordinarily required to fully evaluate vaccine efficacy. However, emergency use may be possible if promising immunogenicity results are observed. A ring vaccination trial, which recruits subjects connected to a known case either socially or geographically, is a solution to evaluate vaccine efficacy and control the spread of the disease simultaneously although its conduct is challenging. Nevertheless, when COVID-19 becomes a recurrent epidemic, an 'individual-level' efficacy trial is preferred. Innovative statistical designs, including seamless design, platform trial, master protocol design, are helpful to accelerate clinical development. A seamless Phase I/II design has been applied in multiple COVID-19 vaccine studies to date. However, Phase II/III design should be done very carefully. The control of type I error, maintaining trial blinding and statistical methods leading to unbiased estimates should be pre-specified in the clinical protocol. A Data Safety Monitoring Board is especially important, given the need to assure an adequate level of safety when society want a safe and effective vaccine.

Abstract
Objective The systemic inflammation index and body mass index (BMI) are easily accessible markers that can predict mortality. However, the prognostic value of the combined use of these two markers remains unclear. The goal of this study was therefore to evaluate the association of these markers with outcomes based on a large cohort of patients with gastric cancer. Methods A total of 2,542 consecutive patients undergoing radical surgery for gastric or gastroesophageal junction adenocarcinoma between 2009 and 2014 were included. Systemic inflammation was quantified by the preoperative neutrophil-to-lymphocyte ratio (NLR). High systemic inflammation was defined as NLR ≥ 3, and underweight was defined as BMI < 18.5 kg/m2. Results Among 2,542 patients, NLR ≥ 3 and underweight were common [627 (25%) and 349 (14%), respectively]. In the entire cohort, NLR ≥ 3 or underweight independently predicted overall survival (OS) [hazard ratio (HR): 1.236, 95% confidence interval (95% CI): 1.069-1.430; and HR: 1.600, 95% CI: 1.350-1.897, respectively] and recurrence-free survival (RFS) (HR: 1.230, 95% CI: 1.054-1.434; and HR: 1.658, 95% CI: 1.389-1.979, respectively). Patients with both NLR ≥ 3 and underweight (vs. neither) had much worse OS (HR: 2.445, 95% CI: 1.853-3.225) and RFS (HR: 2.405, 95% CI: 1.802-3.209). Furthermore, we observed similar results in subgroup analyses according to pathological stage, age, and postoperative chemotherapy. Conclusions Our results showed that preoperative elevated NLR and decreased BMI had a significant negative effect on survival. Underweight combined with severe inflammation could enhance prognostication. Taking active therapeutic measures to reduce inflammation and increase nutrition may help improve outcomes.

Abstract
Background: Hepatitis A vaccine has been used in mass and routine public vaccination programs in China. Long-term follow-up studies are required to determine the duration of protection and the need for booster vaccinations. Methods: A prospective, randomized, open-label clinical trial was performed to compare the geometric mean concentration (GMC) and seroprotection rates of anti-Hepatitis A virus (HAV) antibodies elicited by the inactivated vaccines Healive and Havrix. 400 healthy children were randomly assigned 3:1 ratio to receive two doses of Healive or Havrix at 0 and 6 months. Persistence of anti-HAV antibodies for 5 years post immunization has been reported The current study reports new data at 11 years post immunization for the purpose of showing antibody persistence. Sensitivity analyzes were performed to assess the results. In addition, predictions for long-term antibody persistence were performed using a statistical model. Two different serological assays were used that were shown to be 98.3% concordant for detecting anit-HAV antibody. Results: GMCs were significantly higher following Healive compared to Havrix at 1, 6, 7, 66, 112 and 138 months post-vaccination. In addition, the GMCs obtained using sensitivity analysis were very similar to those obtained using the original models. Prediction analysis indicated that the duration of protection for both vaccines was at least 30 years after immunization, with a lower limit of the 95% confidence interval for GMC of greater than 20mIU/mL. Conclusions: Healive is more immunogenic than Havrix in children at 11 years post full immunization. Prediction analysis indicated at least 30 years of antibody persistence for both vaccines.

Abstract
INTRODUCTION The benefits of combining transarterial chemoembolization (TACE) and sorafenib (TACE-S) over TACE alone for treatment of unresectable hepatocellular carcinoma (HCC) remain controversial. Yet, such populations are heterogeneous in terms of baseline characteristics. OBJECTIVE To investigate the predictors of survival benefits from added sorafenib and identify the potential candidates for TACE-S. METHODS This multicenter observational study was conducted in 17 Chinese tertiary hospitals for patients with unresectable, liver-confined HCC. Eligible patients with performance status score of ≤1 and Child-Pugh score of ≤7 were treated with TACE or TACE-S. Interactions between treatment and baseline variables were evaluated to find indicators for survival benefits, based on which the patients were stratified. Multivariate models adjusted for baseline characteristics or propensity score were used to compare overall survival (OS) and time to tumor progression (TTP). RESULTS From January 2009 to December 2015, 1,719 consecutive patients received TACE (n = 1,406) or TACE-S (n = 313). Although TACE-S compared with TACE improved TTP (adjusted hazard ratio [HR] 0.75, p = 0.008), no difference in OS was observed (adjusted HR 0.87, p = 0.090). Nevertheless, the tumor burden (sum of maximum diameter of largest tumor [cm] and tumor number) and albumin-bilirubin (ALBI) score independently predicted the survival benefits from added sorafenib (interaction p< 0.001). For patients with either moderate tumor burden (7-13) or low ALBI score (no more than -2.8) defined as candidates, TACE-S prolonged OS (adjusted HR 0.73, p = 0.003) and TTP (adjusted HR 0.72, p = 0.014) compared to TACE alone, whereas its superiority disappeared in non-candidates. CONCLUSIONS Not all unresectable HCC patients but those with moderate tumor burden or low ALBI score achieve survival benefits from TACE-S compared with TACE alone. Future randomized controlled trials focusing on the subset are warranted.

Abstract
In survival trials with fixed trial length, the patient accrual rate has a significant impact on the sample size estimation or equivalently, on the power of trials. A larger sample size is required for the staggered patient entry. During enrollment, the patient accrual rate changes with the recruitment publicity effect, disease incidence and many other factors and fluctuations of the accrual rate occur frequently. However, the existing accrual models are either over-simplified for the constant rate assumption or complicated in calculation for the subdivision of the accrual period. A more flexible accrual model is required to represent the fluctuant patient accrual rate for accurate sample size estimation. In this paper, inspired by the flexibility of the Gaussian mixture distribution in approximating continuous densities, we propose the truncated Gaussian mixture distribution accrual model to represent different variations of accrual rate by different parameter configurations. The sample size calculation formula and the parameter setting of the proposed accrual model are discussed further.

Abstract
Background The prognosis of female breast cancer (BC) patients is determined by many clinicopathological factors. In this study, we aimed to identify prognostic factors for BC and develop reliable nomograms to predict the 1-, 3-, and 5-year overall survival (OS) and breast cancer-specific survival (BCSS). Methods The Surveillance, Epidemiology, and End Results (SEER) database was used to screen 227,989 eligible patients as the study cohort. The whole cohort was randomly divided into a training cohort (n=113,996) and a testing cohort (n=113,993). The log-rank test and Cox proportional hazards analysis were applied to select variables and build nomogram models based on the training cohort. Internal and external validation were performed to evaluate the performance of the models by calculating the C-index and generating calibration plots in the training cohort and testing cohort. Results The following factors were included in both the OS and BCSS nomograms: subtypes of BC, metastasis (bone, liver, lung, and brain), age at diagnosis, race, tumor size, grade, number of positive lymph nodes, and marital status. The calibration plots presented excellent consistency between the actual and nomogram-predicted survival probabilities in both the training cohort and testing cohort. The C-index values of the nomograms were 0.796 and 0.793 for OS and 0.856 and 0.853 for BCSS in the training and testing cohorts, respectively. Conclusions The established nomograms provide a visualization of the risk of each prognostic factor and can assist clinicians in predicting the 1-, 3-, and 5-year OS and BCSS for all 4 subtypes of BC.

Abstract
BACKGROUND Angioplasty recanalisation is recommended as the first-line interventional procedure for Budd-Chiari syndrome, but subsequent restenosis is common. We aimed to test whether use of routine, non-selective stenting in angioplasty could improve patency and treatment efficacy with adequate safety in Budd-Chiari syndrome. METHODS We did a randomised controlled trial, for which patients aged 18-75 years with Budd-Chiari syndrome with membranous obstruction or short-length stenosis (≤4 cm), and a Child-Pugh score of less than 13 were considered eligible. Patients were excluded if they had obstruction not amenable to angioplasty, were recommended to be treated with transjugular intrahepatic portosystemic shunt or liver transplantation, or had contraindications for angioplasty. Eligible patients were randomly assigned (1:1) to an angioplasty-only group or an angioplasty plus routine stenting group, with use of a web-based allocation system (Pocock and Simon's minimisation method, stratified by obstruction features and Child-Pugh score). Recanalisation procedures were done within 24 h of randomisation. The statistician and investigators responsible for data collection data and endpoint assessment were masked to group allocation. The primary outcome was the proportion of patients free of restenosis, analysed in the intention-to-treat population. The study is registered on ClinicalTrials.gov (NCT02201485) and is completed. FINDINGS Between July 28, 2014, and Sept 29, 2017, 88 (59%) of 150 screened patients were enrolled and assigned either the angioplasty-only group (n=45) or the angioplasty plus routine stenting group (n=43). During a median follow-up period of 27 months (IQR 19-41), the angioplasty plus routine stenting group had significantly higher proportion of patients free of restenosis (42 [98%] of 43 patients) than did the angioplasty-only group (27 [60%] of 45 patients; p<0·0001). In the survival analysis, 3-year restenosis-free survival was 96·0% (95% CI 88·6-100·0) in the routine stenting group versus 60·4% (46·4-78·7) in the angioplasty-only group (log-rank p<0·0001). The hazard ratio for restenosis was 0·04 (95% CI 0·01-0·31) in favour of routine stenting, with an absolute risk reduction of 35·6% (95% CI 24·2-55·0). Two (5%) patients in the angioplasty plus routine stenting group and one (2%) patient in the angioplasty-only group died during follow-up. One (2%) patient from the angioplasty plus routine stenting group had puncture site haematoma, which was not related to stenting. No stent fracture or migration occurred. Anticoagulation-related adverse events occurred in five (11%) patients from angioplasty alone group and five (12%) patients from angioplasty plus routine stenting group. INTERPRETATION Routine stenting with angioplasty is superior to angioplasty alone for preventing restenosis in patients with Budd-Chiari syndrome with short-length stenosis and is safe to use as part of first-line invasive treatment. Further validation is needed in similar settings and other regions in which different characteristics of Budd-Chiari syndrome are more prevalent.

Abstract
The effect of reference treatment over placebo, known as M1, is essential in the development of non-inferiority margin. We proposed a M1 adjustment approach to reduce the selection bias for collected data of historical trials. A quantitative illustration of selection bias of historical data is also defined. Simulation study shows that the proposed approaches would significantly reduce the bias when the proportion of positive studies in historical data is noticeably larger than the power of studies include in historical data. When historical data are constituted by only positive studies, the performance of the proposed method is also appreciable. However, when the proportion of positive studies is close to the power of studies included or the number of studies included is too small, the performance of the proposed approach may not be reliable. A real-data application is also presented. The proposed bias-adjustment approach is a reasonable method to reduce the over-estimate of effect size in the specification of non-inferiority margin. It could also be applied in most non-inferiority margin specification methods or be cooperate used with other bias-adjustment approaches.

Abstract
BACKGROUND The survival benefit of early placement of transjugular intrahepatic portosystemic shunts (TIPS) in patients with cirrhosis and acute variceal bleeding is controversial. We aimed to assess whether early TIPS improves survival in patients with advanced cirrhosis and acute variceal bleeding. METHODS We did an investigator-initiated, open-label, randomised controlled trial at an academic hospital in China. Consecutive patients with advanced cirrhosis (Child-Pugh class B or C) and acute variceal bleeding who had been treated with vasoactive drugs plus endoscopic therapy were randomly assigned (2:1) to receive either early TIPS (done within 72 h after initial endoscopy [early TIPS group]) or standard treatment (vasoactive drugs continued to day 5, followed by propranolol plus endoscopic band ligation for the prevention of rebleeding, with TIPS as rescue therapy when needed [control group]). Randomisation was done by web-based randomisation system using a Pocock and Simon's minimisation method with Child-Pugh class (B vs C) and presence or absence of active bleeding as adjustment factors. The primary outcome was transplantation-free survival, analysed in the intention-to-treat population, excluding individuals subsequently found to be ineligible for enrolment. This study is registered with ClinicalTrials.gov, number NCT01370161, and is completed. FINDINGS From June 26, 2011, to Sept 30, 2017, 373 patients were screened and 132 patients were randomly assigned to the early TIPS group (n=86) or to the control group (n=46). After exclusion of three individuals subsequently found to be ineligible for enrolment (two patients in the early TIPS group with non-cirrhotic portal hypertension or hepatocellular carcinoma, and one patient in the control group due to non-cirrhotic portal hypertension), 84 patients in the early TIPS group and 45 patients in the control group were included in the intention-to-treat population. 15 (18%) patients in the early TIPS group and 15 (33%) in the control group died; two (2%) patients in the early TIPS group and one (2%) in the control group underwent liver transplantation. Transplantation-free survival was higher in the early TIPS group than in the control group (hazard ratio 0·50, 95% CI 0·25-0·98; p=0·04). Transplantation-free survival at 6 weeks was 99% (95% CI 97-100) in the early TIPS group compared with 84% (75-96; absolute risk difference 15% [95% CI 5-48]; p=0·02) and at 1 year was 86% (79-94) in the early TIPS group versus 73% (62-88) in the control group (absolute risk difference 13% [95% CI 2-28]; p=0·046). There were no significant differences between the two groups in the incidence of hepatic hydrothorax (two [2%] of 84 patients in the early TIPS group vs one [2%] of 45 in the control group; p=0·96), spontaneous bacterial peritonitis (one [1%] vs three [7%]; p=0·12), hepatic encephalopathy (29 [35%] vs 16 [36%]; p=1·00), hepatorenal syndrome (four [5%] vs six [13%]; p=0·10), and hepatocellular carcinoma (four [5%] vs one [2%]; p=0·68). There was no significant difference in the number of patients who experienced other serious adverse events (ten [12%] vs 11 [24%]; p=0·07) or non-serious adverse events (21 [25%] vs 19 [42%]; p=0·05) between groups. INTERPRETATION Early TIPS with covered stents improved transplantation-free survival in selected patients with advanced cirrhosis and acute variceal bleeding and should therefore be preferred to the current standard of care.

Abstract
PURPOSE Although a series of serious adverse events have continually raised concerns about the potential toxicity of traditional Chinese medicine injections (TCM injections), studies on this subject are still sparse. We conducted a descriptive analysis of a spontaneous reporting system in China to describe the safety profile of TCM injections. METHODS The safety profile of TCM injections is described by descriptive analysis of 559 066 adverse reports collected from Guangdong Provincial Center for adverse drug reaction (ADR) Monitoring in China during 2003 to 2017. RESULTS The percentage of new or serious ADRs of TCM injections is much higher than average percentage of China's spontaneous reporting system (SRS) as a whole (48.70% vs <25%). Compared with conventional injections, TCM injections have a slightly lower percentage of serious ADRs (6.02% vs 6.72%) and much higher percentage of unknown (new) ADRs (46.74% vs 24.13%). The gender and age distribution for TCM injections are similar to conventional injections. The reporting rates of ADRs increased with age. Anaphylactic shock and anaphylactoid reaction are high-risk ADRs for TCM injections and, anaphylactic shock is ranked number 1 in causing deaths (50.00%). CONCLUSIONS There are some differences and similarities on the safety profile between TCM injections and conventional injections. TCM injections have higher risk of adverse effects than any other dosage forms of TCM medications and higher percentage of new or serious adverse effects than conventional injections. A lot of work need to be done to clarify the huge amount of potential unknown adverse effects related to TCM injections.

Abstract
BACKGROUND To validate the robust predictive values of tumor vascularity and hand-foot-skin reaction (HFSR) in combination treatment of transarterial chemoembolization (TACE) and sorafenib for patients with intermediate hepatocellular carcinoma (HCC), and then select the potential candidates who would survive best from such treatment. METHODS A total of 132 treatment-naive patients with intermediate HCC undergoing combination therapy of TACE and sorafenib were recruited between January 2010 and December 2014. The tumor vascularity was defined according to digital subtraction angiography (DSA) and HFSR was assessed by the national cancer institute common terminology criteria for adverse events (NCI-CTCAE). The Mann-Whitney U test was used to assess the correlation between vascularity and radiologic response; time to radiologic progression (TTP) and overall survival (OS) were evaluated using Kaplan-Meier techniques and compared by log-rank test; factors associated with them were evaluated using multivariate Cox regression analysis. RESULTS During a median follow up of 17.3 months, it was revealed that hypervascularity and development of ≥2 grade of HFSR within 60 days after sorafenib initiation were favorable predictors for TTP (HR 0.378, p < 0.001; HR 0.627, p = 0.018) and OS (HR 0.499, p = 0.002; HR 0.555, p = 0.004). The median TTP and OS for patients with both were 12.2 and 29.1 months, which were better than patients with either of them (6.0 months, HR 1.74, p = 0.012; 16.5 months, HR 1.73, p = 0.021), as well as those with neither (2.9 months, HR 3.74, p < 0.001; 11.9 months, HR 3.17, p < 0.001). CONCLUSIONS Tumor hypervascularity and development of ≥2 grade of HFSR within 60 days were favorable predictive factors for the combination treatment of TACE and sorafenib, with both of which the patients survived longest and might be the potential candidates.

Abstract
This study was inspired by the need to estimate pointwise confidence intervals (CIs) for a nonlinear dose-response model from a dose-finding clinical trial. Profile likelihood based CI for a nonlinear dose response model is often recommended. However, it is still not commonly used in dose-finding studies because it cannot generally be calculated explicitly. Most previous research has mainly focused on the performance of the profile likelihood based CI method compared with other common approaches. However, there are still no reports on computing profile likelihood based pointwise CIs for an entire dose-response curve. Based on a previous dose-finding trial with binary-response data, this present study proposed to calculate profile likelihood based pointwise CIs by using the bisection method with proper calculation order for doses in the curve plus crude search when the expected response is close to a boundary. The convergence could be improved by applying appropriate starting values for the optimization procedure with straightforward programming techniques. The algorithm worked well in most cases based on the simulation study and it can be applied more generally to other dose-response models, and other type of data like normally distributed response. It would indeed be great to be able to use profile likelihood approaches more routinely when constructing pointwise CIs for nonlinear dose-response models.

Abstract
Analytical similarity assessment of critical quality attributes (CQAs) serves as a foundation for the development of biosimilar products and facilitates an abbreviated subsequent clinical evaluation. In this study, we establish a statistical evaluation roadmap with statistical approaches for some selected CQAs from Tier 1, because they are most relevant to clinical outcomes and require the most rigorous statistical methods. In the roadmap, we incorporate 3 methods-ranking and tier assignment of quality attributes, the equivalence test, and the Mann-Whitney test for equivalence-that are important to determine analytical similarity between the reference and biosimilar products. For the equivalence test, we develop a power calculation formula based on the two one-sided tests procedure. Exact sample sizes can be numerically calculated. Then, we propose a flexible idea for selecting the number of reference lots (nR) and the number of biosimilar lots (nT) to adjust for serious unbalanced sample sizes. From results of extensive simulations under various parameter settings, we obtain a workable strategy to determine the optimum sample size combination (nT, nR) for the equivalence test of CQAs from Tier 1. R codes are provided to facilitate implementation of the roadmap and corresponding methods in practice.

Abstract
OBJECTIVE Limited data are available on the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis (PVT). This study aimed to compare transjugular intrahepatic portosystemic shunt (TIPS) with covered stents versus endoscopic band ligation (EBL) plus propranolol for the prevention of variceal rebleeding among patients with cirrhosis and PVT. DESIGN Consecutive cirrhotic patients (94% Child-Pugh class A or B) with PVT who had variceal bleeding in the past 6 weeks were randomly assigned to TIPS group (n=24) or EBL plus propranolol group (EBL+drug, n=25), respectively. Primary endpoint was variceal rebleeding. Secondary endpoints included survival, overt hepatic encephalopathy (OHE), portal vein recanalisation and rethrombosis, other complications of portal hypertension and adverse events. RESULTS During a median follow-up of 30 months in both groups, variceal rebleeding was significantly less frequent in the TIPS group (15% vs 45% at 1 year and 25% vs 50% at 2 years, respectively; HR=0.28, 95% CI 0.10 to 0.76, p=0.008), with a significantly higher portal vein recanalisation rate (95% vs 70%; p=0.03) and a relatively lower rethrombosis rate (5% vs 33%; p=0.06) compared with the EBL+drug group. There were no statistically significant differences in survival (67% vs 84%; p=0.152), OHE (25% vs 16%; p=0.440), other complications of portal hypertension and adverse events between groups. CONCLUSION Covered TIPS placement in patients with PVT and moderately decompensated cirrhosis was more effective than EBL combined with propranolol for the prevention of rebleeding, with a higher probability of PVT resolution without increasing the risk of OHE and adverse effects, but this benefit did not translate into improved survival.

Abstract
To evaluate the safety and immunogenicity of a newly 23-valent pneumococcal polysaccharide vaccine (PPV23), a phase Ⅲ clinical trial was conducted in population aged ≥ 2 years. We conducted a randomized, double-blinded, active controlled trial, in which 1760 participants were randomly assigned in a 1:1 ratio to receive one dose of either the test vaccine or the control commercial vaccine. The surveillance period was 28 days. The 2-fold increase rate of anti-pneumococcal for 23 serotypes varied from 49.71% to 90.96% in the treatment group and from 44.52% to 88.24% in the control group. According to -10% non-inferiority margin and 95% confidence intervals of rate difference, all the 23 serotypes of the treatment group were non-inferiority to the control group. The 2-fold increase rate of anti-pneumococcal antibody were significantly higher in the treatment group for 11 serotypes including 1, 2, 3, 4, 10A, 11A, 14, 18C, 20, 22F, and 23F. Serious adverse events occurred in 2 in 879 (0.23%) participants in the treatment group and 2 in 880 (0.23%) participants in the control group, and all the adverse events were unrelated to the vaccination. The overall adverse reaction frequency showed no difference between the treatment (51.19%) and control group (47.95%), and most adverse reactions were mild or moderate in intensity. The newly PPV23 is immunologically non-inferior to the control commercial vaccine and well tolerated in healthy Chinese population aged ≥ 2 years. Trial registration: ClinicalTrial.gov identifier: NCT02451969.

Abstract
Traditional Chinese herbal injection, frequently referred to as TCM injection, has evolved over 70 years as a treatment modality that parallels injections of pharmaceutical products. As the market reach has not been analyzed systematically in the past literature this article performed a descriptive analysis of various aspects of TCM injections based on the following data sources: (1) information retrieved from website of drug registration system of China, and (2) regulatory documents, annual reports and ADR Information Bulletins issued by drug regulatory authority. As of December 31, 2017, 134 generic names of TCM injections from 224 manufacturers were approved for sale. Only 5 of the 134 TCM injections are documented in the present version of Ch.P (2015). Most TCM injections are documented in drug standards other than Ch.P. The formulation, ingredients and routes of administration of TCM injections are more complex than conventional chemical injections. Ten TCM injections are covered by national lists of essential medicine and 58 are covered by China's basic insurance program (2017). ADR reports related to TCM injections accounts for >50% of all ADR reports related to TCMs and the percentages have been rising annually. Making traditional medicine injectable might be a promising way to develop traditional medicines. However, many practical challenges need to be overcome by further development before a brighter future for injectable traditional medicines can reasonably be expected.

Abstract
Background & Aims Sorafenib-related adverse events have been reported as clinical surrogates for treatment response in hepatocellular carcinoma (HCC); however, no consensus has been reached regarding the definition of responders. We evaluated the predictive abilities of different definitions for sorafenib response based on treatment-emergent adverse events, aiming to identify the most discriminatory one as a clinical marker. Methods From January 2010 to December 2014, 435 consecutive HCC patients treated with sorafenib were enrolled. Considering the type, severity and timing of adverse events, twelve different categories of sorafenib response were defined. By comparing their discriminatory abilities for survival, an indicative criterion was defined, the prognostic value of which was evaluated by time-dependent multivariate analysis, validated in various subsets and confirmed by landmark analysis. Results Using concordance (C)-index analysis and time-dependent receiver operating characteristic curves, the development of a hand-foot-skin reaction ≥ grade 2 within 60 days of sorafenib initiation (2HFSR60) showed the highest discriminating value. Based on this criterion, 161 (37.0%) sorafenib responders achieved decreased risk of death by 47% (adjusted HR 0.53, 95%CI 0.43-0.67, P < 0.001) and likelihood of progression by 26% (adjusted HR 0.74, 95%CI 0.58-0.96, P = 0.020) compared with non-responders. Notably, 2HFSR60 remained an effective discriminator among most subgroups and had superior predictive ability to previous definitions, even according to the landmark analysis. Conclusions Our study demonstrated that 2HFSR60, with the best discriminatory ability compared to currently available definitions of sorafenib-related adverse events, could be the optimal clinical marker to identify sorafenib responders with decreased risk of death by half.

Abstract
BACKGROUND Biostatistics is a key but challenging subject in medical curricula that is usually delivered via a didactic approach in China. However, whether it is the best teaching approach to improve the learner's competency, especially for medical postgraduates is yet to be proved. Therefore, a block curriculum design was initially developed to provide selective education to the postgraduates towards the professional career of their interest. A questionnaire was designed to assess the students' perceptions toward biostatistics as these affective factors might impact the learning process. Thus, the present study aimed to detect whether the new block curriculum design could promote the students' positive perceptions and further improve the course achievement. METHODS This cohort study investigated and assessed the perceptions toward biostatistics of the first-year postgraduates undergoing traditional teaching and block teaching, respectively. Structural equation modeling was applied to explore the association between perception and course achievement in the block teaching group. RESULTS With a response rate of 97.84 and 96.67% from the two cohorts respectively, 499 block teaching postgraduates had more positive perceptions as compared to 465 traditionally teaching postgraduates with Likert 5-point agreement response mean of 3.50 vs. 3.31 for course value, 3.66 vs. 2.97 for course comment, and 4.29 vs. 4.10 for expectation. Moreover, block teaching students presented superior confidence about academic statistical knowledge, and therefore, 77.96% of them approved of the new teaching approach. Age, specialty, research experience, logical thinking capacity, mathematical basics, and computer basics might influence the postgraduates' self-assessment ability (all P < 0.05). Structural equation modeling confirmed a positive correlation between perceptions and the course achievements with a reasonable fit. CONCLUSIONS The block curriculum design in the biostatistics course improved the postgraduates' positive perception and may have had a positive role in improving postgraduates' achievement in learning biostatistics.

Abstract
Objective: To evaluate the efficacy and safety of a domestic human plasma derived coagulation Factor Ⅸ concentrate (pd-FⅨ) in patients with hemophilia B. Methods: The study was a multicenter, open-label and single-arm study. The efficacy of pd-F Ⅸ was evaluated by objective performance criteria. The doses of pd-FⅨ were calculated according to the bleeding symptom and disease severity. The infusion efficiency of pd-FⅨ and improvement of bleeding symptoms were measured at 30 minutes and (24±4) h after the first infusion, respectively. Adverse events were recorded. Viral infection and FⅨ inhibitor were detected 90 d after the first infusion. Results: All 36 subjects with hemophilia B were enrolled in the study. The median age of these patients was 31 years old and the median injection doses were 4 (1-17) times. The hemostatic effect of 27/36 (75.00%) and 9/36 (25.00%) acute bleeding events were rated as "excellent" and "better" , respectively. The recovery rate was 111.92% (65.55%-194.28%) at 30 minutes after infusion of FⅨ. There was no adverse event related to FⅨ. No reactivation of HBV, HCV or HIV and FⅨ inhibitor was detected at 90-104 d after the first FⅨ infusion. Conclusion: This domestically made human plasma derived FⅨ concentrate is safe and effective in the treatment of acute bleeding in patients with hemophilia B.

Abstract
BACKGROUND The effectiveness of active pharmacovigilance depends on the specific methods adopted and the work patterns put into place. Over the past few years, much attention has been paid to the importance of implementing such systems in China. However, less has been done to evaluate the state of implementation and future needs of such systems. METHODS This paper reviews China's recent approaches to active pharmacovigilance by examining: (1) information collected from scientific articles and the websites of the China Food and Drug Administration and the China National Center for Adverse Drug Reaction Monitoring, (2) information available on China's spontaneous reporting systems (SRS) and active pharmacovigilance system, and (3) annual reports and internal reports on this subject. RESULTS Areas that improved most meaningfully for China's active pharmacovigilance in recent years appear to include: (1) quicker reporting and more intelligent scanning methods for adverse drug reactions (ADRs), (2) the use of pharmacovigilance approaches to mine electronic hospital records, and (3) the development of integrated systems including the China Hospital Pharmacovigilance System and China Sentinel Hospital Alliance Program. CONCLUSION Not only has the national online SRS system provided a platform for passive pharmacovigilance, it has also become an important platform for various explorations of active pharmacovigilance in China. Quick reporting and intelligent scanning of ADRs, facilitated by automated ADR detection based on electronic hospital records, have accelerated to capabilities for active pharmacovigilance. The outcomes of the programs, such as the China Hospital Pharmacovigilance System and China Sentinel Hospital Alliance Program, usher in a new era for China's active pharmacovigilance. These are particularly important to bridge the information system of sentinel hospitals and ADR research centers, but gaps remain. Thus, much work needs to be done before a high-level active pharmacovigilance system is sufficiently mature to ensure drug safety in the country.

Abstract
AIM AND BACKGROUND Proton pump inhibitors (PPIs) are the main drugs for the treatment of reflux esophagitis. Phase II clinical trials showed that, compared with Esomeprazole, the new PPI Ilaparazole is great in terms of efficacy for reflux symptoms relief and curling for esophagitis. The aim of this study was to confirm suitable dose of Ilaparazole in the treatment of reflux esophagitis. METHODS This study used a randomized, double-blind, parallel positive drug control, multi-center design. A total of 537patients diagnosed as reflux esophagitis by gastroscopy were randomly divided into Ilaparazole group (n = 322, Ilaparazole 10 mg QD) and esomeprazole group (n = 215, Esomeprazole 40 mg QD). The patients in the two groups were treated for 8 weeks. Heartburn and reflux symptoms prior to treatment, and 2, 4 and 8 weeks after the treatment were assessed. Gastroscopy was performed after 4 weeks of treatment. Unhealed patients within 4 weeks underwent gastroscopy again at the end of 8 weeks. RESULTS A total of 471 cases completed the treatment. In Esomeprazole and Ilaparazole groups. After 8 weeks treatment, the healing rate in Esomeprazole group and Ilaparazole group were 82.79% (94.94%) and 83.54% (92.50%), respectively. The corresponding rate difference [Ilaparazole-esomeprazole] was 0.75% (-2.44%) and the two-sided 95% CI was -5.72 to 7.22 (-6.90 to 2.01). The symptom disappearance rates for FAS (PPS) were 75.81% (82.02%) and 76.71% (80.36%) P = 0.8223 (0.7742). Adverse reactions related to the drugs were: 10.70% and 11.80%, (P = 0.7817). CONCLUSIONS The efficacy and safety of Ilaparazole (10 mg/day) in treating reflux esophagitis was similar to esomeprazole (40 mg/day). Ilaparazole (10 mg/day) can be used in the treatment of esophagitis. The clinical trial registration number of the study is NCT 02860624.

Abstract
BACKGROUND & AIMS Currently, there are no recommendations in guidelines concerning the preferred diameter of stents for transjugular intrahepatic portosystemic shunt (TIPS), owing to the lack of adequate evidence. We therefore compared 8mm stents with 10mm stents, to evaluate whether 8mm stents would achieve similar shunt function, with less hepatic encephalopathy (HE) and better liver function. METHODS Cirrhotic patients were randomly assigned to receive TIPS with an 8mm or 10mm covered stent to prevent variceal rebleeding. The primary endpoint was shunt dysfunction. All-cause rebleeding, orthotopic liver transplantation (OLT)-free survival, their composite endpoint, overt HE (overall and spontaneous) and liver function were designated as the secondary endpoints. RESULTS From July 2012 to January 2014, 64 and 63 patients were allocated to the 8mm and 10mm groups, respectively. During a median follow-up of 27months in both arms, dysfunction rates (16% vs. 16% at two years, p=0.62), two-year rebleeding (16% vs. 17%, p=0.65), OLT-free survival (95% vs. 86%, p=0.37), and the composite endpoint (p=0.62) were not statistically different between the groups. Despite a marginal decrease in overall overt HE, there were significantly fewer spontaneous overt HE incidents in the 8mm group within two years (27% vs. 43%, p=0.03), with a risk reduction of 47%. Notably, patients receiving 8mm stents also developed less hepatic impairment. CONCLUSIONS TIPS with 8mm covered stents showed similar shunt function to TIPS with 10mm stents, but halved the risk of spontaneous overt HE and reduced hepatic impairment. Therefore, 8mm TIPS stents should be preferred for the prevention of variceal rebleeding in cirrhotic patients. Lay summary: The optimal diameter for transjugular intrahepatic portosystemic shunt (TIPS) remained uncertain. This study showed that TIPS with 8mm covered stents did not compromise shunt patency, or influence the efficacy of variceal rebleeding prevention compared to TIPS with 10mm stents, but reduced the risk of spontaneous overt hepatic encephalopathy and the incidence of severe encephalopathy. Moreover, liver function reserve was also better in the 8mm stents group, suggesting that 8mm TIPS stents should be preferred for the prevention of variceal rebleeding in cirrhotic patients.

Abstract
PURPOSE To investigate treatment outcome, prognostic factors for overall survival, and appropriate candidates for transarterial chemoembolization among patients with hepatocellular carcinoma (HCC) and extrahepatic spread (EHS). MATERIALS AND METHODS From January 2010 to June 2014, 111 consecutive patients with HCC and EHS treated by transarterial chemoembolization alone were evaluated. Factors associated with overall survival were evaluated using Cox regression analysis, and a scoring equation was established to subgroup patients with EHS. RESULTS Median follow-up was 3.8 months, and median overall survival was 3.8 months (95% confidence interval [CI], 2.9-4.7 months). Multivariate analysis demonstrated maximum tumor size ≥ 10 cm (hazard ratio [HR] 1.58; 95% CI, 1.02-2.46; P = .041), multifocal intrahepatic tumors (HR 1.55; 95% CI, 1.03-2.33; P = .037), and portal vein tumor thrombosis (PVTT) (HR 1.81; 95% CI, 1.12-2.91; P = .015) as significant predictors of overall survival. Based on these factors, a scoring equation was developed to predict treatment outcome of transarterial chemoembolization, with an area under the receiver operating characteristic curve of 0.76 in predicting 6-month survival. Using a cutoff score of 5.5, patients with HCC and EHS were divided into 2 groups with significantly different overall survival (8.1 months for EHS1 and 2.4 months for EHS2; P < .001). The described method of subgrouping remained discriminatory regardless of baseline characteristics. CONCLUSIONS Maximum tumor size, intrahepatic tumor distribution, and presence of PVTT were significant determinants of overall survival for patients with HCC and EHS. Transarterial chemoembolization may be appropriate for patients with EHS but lower intrahepatic tumor burden.

Abstract
The primary objective of a multiregional clinical trial (MRCT) is to assess the efficacy of all participating regions and evaluate the probability of applying the overall results to a specific region. The consistency assessment of the target region with the overall results is the most common way of evaluating the efficacy in a specific region. Recently, Huang et al. (2012) proposed an additional trial in the target region to an MRCT to evaluate the efficacy in the target ethnic (TE) population under the framework of simultaneous global drug development program (SGDDP). However, the operating characteristics of this statistical framework were not well considered. Therefore, a nested group sequential program for regional efficacy evaluation is proposed in this paper. It is an extension of Huang's SGDDP framework and allows interim analysis after MRCT and in the course of local clinical trial (LCT) phase. It is able to well control the family-wise type I error in the program level and enhances the flexibility of the program. In LCT sample size estimation, we introduce virtual trial, which is transformed from the original program by using discounting factor, and an iteration method is employed to calculate the sample size and stopping boundaries of interim analyses. The proposed sample size estimation method is validated in the simulations and the effect of varied weight, effect size of TE population, and design setting is explored. Examples with normal end point, binary end point, and survival end point are shown to illustrate the application of the proposed nested group sequential program.

Abstract
BACKGROUND The type 2 component of the oral poliovirus vaccine is targeted for global withdrawal through a switch from the trivalent oral poliovirus vaccine (tOPV) to a bivalent oral poliovirus vaccine (bOPV). The switch is intended to prevent paralytic polio caused by circulating vaccine-derived poliovirus type 2. We aimed to assess the immunogenicity and safety profile of 6 vaccination schedules with different sequential doses of inactivated poliovirus vaccine (IPV), tOPV, or bOPV. METHODS A randomized controlled trial was conducted in China in 2015. Healthy newborn babies randomly received one of the following 6 vaccination schedules: cIPV-bOPV-bOPV(I-B-B), cIPV-tOPV-tOPV(I-T-T), cIPV-cIPV-bOPV(I-I-B), cIPV-cIPV-tOPV(I-I-T), cIPV-cIPV-cIPV(I-I-I), or tOPV-tOPV-tOPV(T-T-T). Doses were administered sequentially at 4-6 week intervals after collecting baseline blood samples. Patients were proactively followed up for observation of adverse events after the first dose and 30 days after all doses. The primary study objective was to investigate the immunogenicity and safety profile of different vaccine schedules, evaluated by seroconversion, seroprotection and antibody titer against poliovirus types 1, 2, and 3 in the per-protocol population. RESULTS Of 600 newborn babies enrolled, 504 (84.0%) were included in the per-protocol population. For type 1 poliovirus, the differences in the seroconversion were 1.17% (95% CI = -2.74%, 5.08%) between I-B-B and I-T-T and 0.00% (95% CI: -6.99%, 6.99%) between I-I-B and I-I-T; for type 3 poliovirus, differences in the seroconversion were 3.49% (95% CI: -1.50%, 8.48%) between I-B-B and I-T-T and -2.32% (95% CI: -5.51%, 0.86%) between I-I-B and I-I-T. The non-inferiority conclusion was achieved in both poliovirus type 1 and 3 with the margin of -10%. Of 24 serious adverse events reported, no one was vaccine-related. CONCLUSIONS The vaccination schedules with bOPV followed by one or 2 doses of IPV were recommended to substitute for vaccinations involving tOPV without compromising the immunogenicity and safety in the Chinese population. The findings will be essential for policy formulation by national and global authorities to facilitate polio elimination.

Abstract
A biosimilar refers to a follow-on biologic intended to be approved for marketing based on biosimilarity to an existing patented biological product (i.e., the reference product). To develop a biosimilar product, it is essential to demonstrate biosimilarity between the follow-on biologic and the reference product, typically through two-arm randomization trials. We propose a Bayesian adaptive design for trials to evaluate biosimilar products. To take advantage of the abundant historical data on the efficacy of the reference product that is typically available at the time a biosimilar product is developed, we propose the calibrated power prior, which allows our design to adaptively borrow information from the historical data according to the congruence between the historical data and the new data collected from the current trial. We propose a new measure, the Bayesian biosimilarity index, to measure the similarity between the biosimilar and the reference product. During the trial, we evaluate the Bayesian biosimilarity index in a group sequential fashion based on the accumulating interim data, and stop the trial early once there is enough information to conclude or reject the similarity. Extensive simulation studies show that the proposed design has higher power than traditional designs. We applied the proposed design to a biosimilar trial for treating rheumatoid arthritis.

Abstract
The mRECIST and dermatologic adverse events (AEs) can be used to assess the patient response to transarterial chemoembolization (TACE) and/or sorafenib for hepatocellular carcinoma (HCC). Here, we aimed to combine the two criteria to stratify the prognosis in patients with unresectable HCC receiving TACE plus sorafenib (TACE-S). In total, 176 consecutive HCC patients treated with TACE-S were enrolled. CT scans and laboratory tests were conducted pretreatment (at baseline, 5-7 days before the TACE-S) and post-treatment (at 1, 2 and 3 months). The radiological response was assessed according to mRECIST. Sorafenib-related AEs were recorded every 2 weeks after oral administration, and patients with dermatologic AEs of Grade 2 or more were defined as dermatologic responders. The earliest time at which mRECIST and dermatologic responses correlated with survival was 2 months after therapy. The mRECIST-dermatologic AE combination assessment stratified patients into three different prognoses; responders on both assessments exhibited the longest median overall survival (OS), followed by responders on one assessment and non-responders on both assessments (30.5, 17.4 and 8.3 months, respectively; p < 0.001). Achieving the highest C-index, the mRECIST-dermatologic AE combination showed better performance in predicting survival than either mRECIST or dermatologic AEs alone. Furthermore, the mRECIST-dermatologic AE combination remained a significant predictor of OS, even when the patients were stratified according to the BCLC stage, ECOG score or alpha-fetoprotein (AFP) value. This study showed that the combination of mRECIST response and dermatologic AEs is superior to either criterion used alone for predicting the survival of HCC patients treated with TACE-S.

Abstract
BACKGROUND Inactivated vaccines for hepatitis A virus (HAV) infection are widely used in China. Mass vaccination programs drive the need for data on long-term persistence of vaccine-induced protection. METHODS A prospective, randomized, open-label clinical trial was conducted to compare geometric mean concentrations (GMCs) and seroconversion rates (SRs) of anti-HAV antibody elicited by the inactivated vaccines Healive and Havrix for 5 y post immunization, in which 400 healthy children were randomly assigned in a 3:1 ratio to receive 2 doses of Healive or Havrix at 0 and 6 month. Anti-HAV antibody concentration was detected by microparticle enzyme immunoassay (MEIA) during the study. Furthermore, an attempt was made to predict persistence of protective immunogenicity by using a suitable statistical model. RESULTS The GMCs were significantly higher after vaccination with Healive than after Havrix as comparator vaccine at 1, 6, 7, 18, 30, 42, 54 and 66 month (P < 0.01) with the peak point at 7 month (3427.2 mIU/ml for Healive and 1441.9 mIU/ml for Comparator). Similarly significant differences of SRs were found between the 2 groups at 1 and 6 month (P < 0.01). Afterwards, the SRs of both groups reached 100% at 7 month and did not decline until 66 month(99.1% for Healive and 97.5% for Comparator). A linear mixed model with a change point at 18 month(Model 3) was found to be suitable to predict persistence of protective immunogenicity induced by vaccines. It was estimated that the duration of protection for Healive was at least 20 y with a lower limit of GMC 95% confidence interval (CI) no less than 20 mIU/mL. CONCLUSIONS Compared with Havrix, the new preservative-free inactivated hepatitis A vaccine (Healive) in 2 doses showed better persistence of antibody concentrations for 5 y after full-course immunization among children and the persistence of protective immunogenicity was estimated for at least 20 y.

Abstract
Streptococcus pneumoniae is an important pathogen causing invasive diseases such as sepsis, meningitis, and pneumonia. Vaccines have become the most effective way to prevent pneumococcal infections. This phase III trial was designed to evaluate the immunogenicity and safety of a 23-valent pneumococcal polysaccharide vaccine in Chinese healthy population aged >2 years. We conducted a randomized, double-blinded, active-controlled, multicenter trial in which 1660 healthy population (>2 years of age) were randomly assigned in a 1 : 1 ratio to receive 2 intramuscular doses of either the treatment vaccine or the active control vaccine, PNEUMOVAX 23. The surveillance period was 30 days. The primary end point was the 2-fold increase rate of anti-pneumococcal antibody for all 23 included serotypes in each group. In the intention-to-treat cohort, the 2-fold increase rate of anti-pneumococcal antibody for 23 included serotypes varied from 62.47% to 97.01% in the treatment group, and from 51.49% to 95.77% in the control group. According to -10% non-inferiority margin and 95% confidence intervals of rate difference, almost all included serotypes of the treatment group reached non-inferiority to control group except for serotype 6B, the lower limit of rate difference of which was -10.00%, equal to the non-inferiority margin. The 2-fold increase rates of anti-pneumococcal antibody were significantly higher in the treatment group for serotype 2, 3, 4, 10A, 11A and 20. Furthermore, for all 23 serotypes, IgG geometric mean concentrations (GMCs) at day 30 were significantly higher in treatment group for serotype 2, 3, 4, 9 V, 10A, 11A, 15 B, 18C, 19 A, 22 F and 33 F. Higher geometric mean fold increase (GMFI) were also observed in the treatment group correspondingly. Serious adverse events occurred in 3 of 830 participants in the treatment group (0.36%) and 2 of 830 participants in the control group (0.24%). No death occurred during the trial. The frequencies of both solicited and unsolicited adverse events (AEs) were small lower in the treatment group (34.34% vs 35.66% for solicited AEs, 4.34% vs 5.42% for unsolicited AEs). Both vaccines were well tolerated and most AEs were mild or moderate in intensity. The newly vaccine was well tolerated and immunologically non-inferior to the active control vaccine PNEUMOVAX 23 for all 23 vaccine serotypes in the Chinese population (>2 years of age).

Abstract
Human enterovirus 71 (EV71) is a causative agent of hand, foot, and mouth disease (HFMD). In a previous phase III trial in children, a human diploid cell-based inactivated EV71 vaccine elicited EV71 specific immune responses and protection against EV71 associated HFMD. This study aimed to assess the factors influencing the severity of adverse events observed in this previous trial. This was a randomized, double-blinded, placebo-controlled, phase III clinical trial of a human diploid vaccine carried out in 12,000 children in Guangxi Zhuang Autonomous Region, China (ClinicalTrials.gov: NCT01569581). Solicited events were recorded for 7 days and unsolicited events were reported for 28 days after each injection. Age trend analysis of adverse reaction was conducted in each treatment group. Multiple logistic regression models were built to identify factors influencing the severity of adverse reactions. Fewer solicited adverse reactions were observed in older participants within the first 7 days after vaccination (P < 0.0001), except local pain and pruritus. More severe adverse reactions were observed after the initial injection than after the booster injection. Serious cold or respiratory tract infections (RTI) were observed more often in children aged 6-36 months than in older children. Only the severity of local swelling was associated with body mass index. Children with throat discomfort before injection had a higher risk of serious cold or RTI. These results indicated that the human diploid cell-based vaccine achieved a satisfactory safety profile.

Abstract
This retrospective cohort study aimed to evaluate the prognostic value of the alpha-fetoprotein (AFP) response in advanced-stage hepatocellular carcinoma (HCC) patients treated with sorafenib combined with transarterial chemoembolization. From May 2008 to July 2012, 118 HCC patients with baseline AFP levels >20 ng/ml treated with combination therapy were enrolled. A receiver operating characteristic curve was used to generate a cutoff point for AFP changes for predicting survival. The AFP response was defined as an AFP decrease rate [ΔAFP(%)] greater than the cutoff point. The ΔAFP(%) was defined as the percentage of changes between the baseline and the nadir values within 2 months after therapy. The median follow-up time was 8.8 months (range 1.2-66.9). A level of 46% was chosen as the threshold value for ΔAFP (sensitivity = 53.7%, specificity = 83.3%). The median overall survival was significantly longer in the AFP response group than in the AFP non-response group (12.8 vs. 6.4 months, P = 0.001). Multivariate analysis showed that ECOG ≥ 1 (HR = 1.95; 95% CI 1.24-3.1, P = 0.004) and AFP nonresponse (HR = 1.71; 95% CI 1.15-2.55, P = 0.009) were associated with increased risk of death. In conclusion, AFP response could predict the survival of patients with advanced-stage HCC at an early time point after combination therapy.

Abstract
BACKGROUND Mecapegfilgrastim (code name HHPG-19K) is a biosimilar to pegylated recombinant human granulocyte-colony stimulating factor (PEG-rhG-CSF). The efficacy and safety of mecapegfilgrastim, using a regimen of once-per-cycle injection of 100-μg/kg or a fixed 6-mg dose, were evaluated for the prophylactic therapy for neutropenia in patients with advanced non-small-cell lung cancer (NSCLC) who were treated with myelosuppressive chemotherapy. MATERIALS AND METHODS Patients were randomized (1:1:1) blindly to 3 treatment arms to receive a single injection of mecapegfilgrastim 100 μg/kg, a 6-mg fixed dose of mecapegfilgrastim, or saline (control) in cycle 1. In cycles 2 to 4 following unblinding at the end of cycle 1, patients in the control arm received daily injections of short-acting rhG-CSF at a dose of 5 μg/kg, whereas patients in the 2 mecapegfilgrastim arms continued the same treatment as in cycle 1. All patients received 4 chemotherapy cycles of docetaxel combined with cisplatin or carboplatin every 21 days. The primary endpoint was the incidence of grade ≥ 3 neutropenia in cycle 1. RESULTS A single dose of 100 μg/kg or a fixed 6-mg dose of mecapegfilgrastim per cycle effectively reduced chemotherapy-induced neutropenia and was comparable to daily rhG-CSF with regard to all efficacy endpoints, including incidence of grade ≥ 3 neutropenia, incidence of febrile neutropenia, duration of grade ≥ 3 neutropenia, and time to neutrophil recovery. No difference in efficacy parameters was observed between the 2-dose regimens of mecapegfilgrastim across all cycles. Mecapegfilgrastim was well-tolerated and was as safe as daily rhG-CSF. CONCLUSION Once-per-cycle injection of mecapegfilgrastim is as effective and safe as daily rhG-CSF for prophylaxis of chemotherapy-induced neutropenia in patients with NSCLC. Mecapegfilgrastim (fixed 6-mg dose) is recommended in clinical practice for its convenient dose management.
