Abstract
BACKGROUND Blocking the interaction between PD-1 and its ligands is a promising treatment strategy for advanced hepatocellular carcinoma. This study aimed to assess the antitumour activity and safety of the anti-PD-1 inhibitor camrelizumab in pretreated patients with advanced hepatocellular carcinoma. METHODS This is a multicentre, open-label, parallel-group, randomised, phase 2 trial done at 13 study sites in China. Eligible patients were aged 18 years and older with a histological or cytological diagnosis of advanced hepatocellular carcinoma, had progressed on or were intolerant to previous systemic treatment, and had an Eastern Cooperative Oncology Group performance score of 0-1. Patients were randomly assigned (1:1) to receive camrelizumab 3 mg/kg intravenously every 2 or 3 weeks, via a centralised interactive web-response system using block randomisation (block size of four). The primary endpoints were objective response (per blinded independent central review) and 6-month overall survival, in all randomly assigned patients who had at least one dose of study treatment. Safety was analysed in all treated patients. This study is registered with ClinicalTrials.gov, number NCT02989922, and follow-up is ongoing, but enrolment is closed. FINDINGS Between Nov 15, 2016, and Nov 16, 2017, 303 patients were screened for eligibility, of whom 220 eligible patients were randomly assigned and among whom 217 received camrelizumab (109 patients were given treatment every 2 weeks and 108 every 3 weeks). Median follow-up was 12·5 months (IQR 5·7-15·5). Objective response was reported in 32 (14·7%; 95% CI 10·3-20·2) of 217 patients. The overall survival probability at 6 months was 74·4% (95% CI 68·0-79·7)]. Grade 3 or 4 treatment-related adverse events occurred in 47 (22%) of 217 patients; the most common were increased aspartate aminotransferase (ten [5%]) and decreased neutrophil count (seven [3%]). Two deaths were judged by the investigators to be potentially treatment-related (one due to liver dysfunction and one due to multiple organ failure). INTERPRETATION Camrelizumab showed antitumour activity in pretreated Chinese patients with advanced hepatocellular carcinoma, with manageable toxicities, and might represent a new treatment option for these patients.

Abstract
Background:
Paclitaxel (PTX) is one of the most important and effective anticancer drugs for
the treatment of human cancer. However, its low solubility and severe adverse effects limited clinical
use. To overcome this limitation, nanotechnology has been used to overcome tumors due to its excellent
antimicrobial activity.
Objective:
This study was to demonstrate the anticancer properties of functionalization silver nanoparticles
loaded with paclitaxel (Ag@PTX) induced A549 cells apoptosis through ROS-mediated signaling
pathways.
Methods:
The Ag@PTX nanoparticles were charged with a zeta potential of about -17 mv and characterized
around 2 nm with a narrow size distribution.
Results:
Ag@PTX significantly decreased the viability of A549 cells and possessed selectivity between
cancer and normal cells. Ag@PTX induced A549 cells apoptosis was confirmed by nuclear condensation,
DNA fragmentation, and activation of caspase-3. Furthermore, Ag@PTX enhanced the anti-cancer
activity of A549 cells through ROS-mediated p53 and AKT signalling pathways. Finally, in a xenograft
nude mice model, Ag@PTX suppressed the growth of tumors.
Conclusion:
Our findings suggest that Ag@PTX may be a candidate as a chemopreventive agent and
could be a highly efficient way to achieve anticancer synergism for human cancers.

Abstract
Near infrared (NIR) fluorescent probes play a crucial role in biological system imaging. A novel NIR fluorescent probe, IR787, was designed in the present study. Compared with indocyanine green (ICG), IR787 showed lower background fluorescent interference and higher fluorescence enhancement. Fluorescence intensities were detected by a Cary Eclipse fluorescence spectrophotometer. The interference of intracellular ions (Cu2+, Ca2+, Mg2+ and Zn2+) on the measurement was negligible, which indicated a good photostability of IR787. MTT assay demonstrated that cell viability of human lung adenocarcinoma epithelial cell line A549 was not significantly affected by the use of the IR787 probe compared with the ICG probe. This result suggested that the IR787 probe was safe for in vitro cell imaging. In vitro NIR optical imaging experiments further revealed cellular uptake and strong intracellular NIR fluorescence of the IR787 probe in A549 cells. The excitation wavelength was 787 nm for IR787. Compared with the previously reported NIR fluorescent probe ICG, the IR787 NIR fluorescent probe had improved prospects for intracellular imaging. IR787 may play a pivotal role in the understanding cell biology, pharmacology and disease diagnosis.

Abstract
Targeted delivery of chemotherapeutics by functionalized nanoparticles exhibits a wonderful prospect for cancer treatment. In this paper, selenium nanoparticles (SeNPs) was linked with hyaluronic acid (HA) to prepare tumor-targeted delivery vehicle HA-SeNPs, and HA-SeNPs was loaded with paclitaxel (PTX) to fabricate functionalized selenium nanoparticles HA-Se@PTX. HA-Se@PTX showed greater uptake in A549 cells in comparison with that in HUVEC, verifying HA-mediated specific uptake of HA-Se@PTX. HA-Se@PTX was capable of entering A549 cells via clathrin-associated endocytosis and showed faster drug release in cancer cell microenvironment in comparison with normal physiological environment. HA-Se@PTX could obviously inhibit the proliferation, migration and invasion of A549 cells and trigger A549 cells apoptosis. Moreover, active targeting functionalized selenium nanoparticles HA-Se@PTX showed greater in vivo antitumor activity compared with free PTX or passive targeting delivery system Se@PTX. In addition, HA-Se@PTX exhibited negligible toxicity on the major organs of mice. In a word, HA-Se@PTX may develop into a valuable nanoscale antitumor drug agent for lung cancer treatment.

Abstract
Liquid biopsies of cancer via single-cell molecular profiling of circulating tumor cells (CTCs) are hampered by the lack of ideal CTC markers. In this study, it is reported that TPN, a bioprobe with aggregation-induced emission (AIE) activity is capable of distinguishing various tumor cells from blood leukocytes based on the difference in cell mitochondria. TPN is a cell-permeant live-cell stain that has little effect on cell viability and integrity, enabling single-cell DNA/RNA analysis with improved efficiency compared with traditional antibody-based methods. Using TPN labeling, CTCs and CTC cluster are detected in the blood from patients with lung or liver cancer. The capability of TPN to identify rare tumor cells in the malignant pleural effusion samples is also demonstrated. Furthermore, RNA sequencing of single lung CTC identified by TPN is successfully performed. The findings presented here provide an antibody-free, low-cost, and nondisruptive approach for detection and genomic characterization of viable tumor cells based on a mitochondria-targeting AIE luminogen. It might serve as a new tool for monitoring of genomics dynamic of tumor and unraveling the mechanisms of tumor metastasis.

Abstract
A Talbot-Lau X-ray Deflectometer (TXD) was implemented in the OMEGA EP laser facility to characterize the evolution of an irradiated foil ablation front by mapping electron densities >1022 cm-3 by means of Moiré deflectometry. The experiment used a short-pulse laser (30-100 J, 10 ps) and a foil copper target as an x-ray backlighter source. In the first experimental tests performed to benchmark the diagnostic platform, grating survival was demonstrated and x-ray backlighter laser parameters that deliver Moiré images were described. The necessary modifications to accurately probe the ablation front through TXD using the EP-TXD diagnostic platform are discussed.

Abstract
Lipid metabolism is a significant section of energy homeostasis, and it affects the development of various cancers. Previous studies have revealed that berberine has strong anticancer and blood lipid-lowering effects. Here, we further investigated the effects of berberine on cell proliferation and lipogenesis in colon cancer cells and the relationship between the two effects. We found that berberine inhibited cell proliferation by inducing G0/G1 phase cell cycle arrest in colon cancer cells. Moreover, the expressions of key lipogenic enzymes were down-regulated by berberine and led to the suppressed lipid synthesis, which was linked to cell proliferation via Wnt/β-catenin pathway. Importantly, berberine inhibited sterol regulatory element-binding protein-1 (SREBP-1) activation and SREBP cleavage-activating protein (SCAP) expression, resulting in the downregulation of these lipogenic enzymes. Knockdown of SCAP by shRNA could abolish the effect of berberine on SREBP-1 activation. Besides the inhibitory effects in vitro, berberine suppressed the growth and lipogenesis of colon cancer xenograft in a SCAP-dependent manner as well. Together, our results suggest that berberine may serve as a candidate against tumor growth of colon cancer partially through targeting SCAP/SREBP-1 pathway driving lipogenesis.

Abstract
Space reduction after the premature loss of the second primary molars is one of the important factors affecting the occurrence of malocclusion, often increasing the demand for orthodontic treatment. It has great significance to select and apply appropriate appliances to maintainthe space soon after the premature loss of the second primary molars. The space should be maintained until the adjacent teeth and the successors erupt successfully. This review summarizes the selection and clinical application of the space maintainer for the premature loss of the second primary molars in different periods, to improve dentists' awareness of the importance of space maintainers and to provide advises for clinical choices.

Abstract
Infiltrated macrophages are an important constituent of the tumor microenvironment and play roles in tumor initiation and progression by promoting immune evasion. However, the molecular mechanism by which macrophage-derived cytokines foster immune escape of colorectal cancer (CRC) is unclear. Here, we demonstrated that macrophage infiltration induced by lipopolysaccharide (LPS) or a high-cholesterol diet (HCD) significantly promoted CRC growth. Similarly, LPS and poly (I:C) remarkably increased the volume of CT26 cell allograft tumors. C-C motif chemokine ligand 5 (CCL5), which is secreted by macrophages, inhibited T-cell-mediated killing of HT29 cells and promoted immune escape by stabilizing PD-L1 in vitro and in vivo. Mechanistically, CCL5 resulted in formation of nuclear factor kappa-B p65/STAT3 complexes, which bound to the COP9 signalosome 5 (CSN5) promoter, leading to its upregulation. Moreover, CSN5 modulated the deubiquitination and stability of PD-L1. High expression of CSN5 in CRC was associated with significantly shorter survival. Furthermore, compound-15 was identified as an inhibitor of CSN5, and destabilized PD-L1 to alleviate the tumor burden. Our results suggest that the novel CCL5-p65/STAT3-CSN5-PD-L1 signaling axis is significantly activated by LPS or HCD-driven macrophage infiltration in an animal model of CRC, which likely has therapeutic and prognostic implications for human cancers.

Abstract
MicroRNAs (miRNAs) function by negatively regulating their target genes. Aberrant expression of baculoviral IAP repeat containing 5 (BIRC5) is associated with the tumor growth and metastasis, however, the clinical significance of miRNAs/BIRC5 axis in gastric cancer (GC) remains unknown. The association of BIRC5 or miR-195-5p/-218-5p expression levels with the clinicopathological characteristics and prognosis in patients with GC was analysed by using a tissue microarray and TCGA dataset. Pearson correlation analysis was used for analysing the correlation of BIRC5 with miR-195-5p/-218-5p expression in GC tissues. Cox proportional hazard regression model was conducted to assess whether BIRC5 or miR-195-5p/-218-5p was an independent prognostic factor in patients with GC. We found that BIRC5 expression levels were increased in GC tissues as compared with the adjacent normal tissues, and acted as an independent prognostic factor of tumor recurrence in patients with GC. Increased expression of BIRC5 was traceable to the dysregulation of miR-195-5p/-218-5p rather than its genetic and epigenetic alterations in GC tissues. MiR-195-5p/-218-5p displayed a negative correlation with BIRC5 expression, and acted as independent prognostic factors of poor prognosis in patients with GC. In conclusion, dysregulation of miR-195-5p/-218-5p/BIRC5 axis predicts a poor prognosis in patients with gastric cancer.

Abstract
Background and Purpose: The clinical use of tirofiban for patients with acute ischemic stroke (AIS) who underwent mechanical thrombectomy (MT) remains controversial. We aimed to evaluate the safety and efficacy of tirofiban combined with MT in AIS patients. Methods: Patients with AIS who underwent MT from January 2014 to December 2018 were enrolled in three stroke units in China. Subgroup analyses were performed based on stroke etiology which was classified according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria. Safety outcomes were in-hospital intracerebral hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH) and mortality at 3-month. Efficacy outcomes were favorable functional outcome and functional independence at 3-month and neurological improvement at 24 h, 3 d and discharge. Results: In patients with large artery atherosclerosis (LAA) stroke, multivariate analyses revealed that tirofiban significantly decreased the odds of in-hospital ICH (adjusted OR = 0.382, 95% CI 0.180–0.809) and tended to increase the odds of favorable functional outcome at 3-month (adjusted OR = 3.050, 95% CI 0.969–9.598). By contrast, in patients with cardioembolism (CE) stroke, tirofiban was not associated with higher odds of favorable functional outcome at 3-month (adjusted OR = 0.719, 95% CI 0.107–4.807), but significantly decreased the odds of neurological improvement at 24 h and 3d (adjusted OR = 0.185, 95% CI 0.047–0.726; adjusted OR = 0.268, 95% CI 0.087–0.825). Conclusions: Tirofiban combined with MT appears to be safe and effective in LAA patients, but has no beneficial effect on CE patients.

Abstract
Methodological processes for nuclear power plant (NPP) pressure vessels' (PV) neutron fluence rate determination take the form of experimental measurement or theoretical calculations. However, the process of experimental measurement takes longer periods, as it requires the incorporation of surveillance capsules into a PV system undergoing normal NPP operation. Therefore, strong reliance on computation and modeling of radiation-induced degradation is given much attention. In this work, the VENUS-3 benchmark has been analyzed using SuperMC code, with the intention of validating SuperMC for accurate reactor neutronics; dosimetry response calculations for in-core/ex-core structural components, particularly with respect to the VENUS-3 configuration type pressurized water reactors (PWRs). In this work, complete three-dimensional (3D) geometry including the source modeling for VENUS-3 facility has been developed with SuperMC. Neutron transport and calculations of equivalent fission flux for the experimental target quantities, 115In (n, n′), 58Ni (n, p), and 27Al (n, α), are also achieved. The calculation results show good agreement with the experimental measurement. The greater majority of the calculated values (C/E) were within the required accuracy of ±10% for reactor components' dosimetry calculations. Most of the calculated values were contained within 5% deviation from the experimental data. Additional calculations and detailed analysis for fast neutron flux distribution and iron displacement per atom rate (dpa/s), including the characteristic effect of partial length shielded assembly (PLSA) on VENUS-3 core barrel, are also discussed. It is therefore evidenced that the effectiveness of SuperMC code for in-core/ex-core reactor neutronics computations has been convincingly demonstrated through the VENUS-3 benchmark testing.

Abstract
Objective:The aim of this study is to investigate the voice function change in patients who underwent total thyroidectomy between preoperative and the third day postoperative, Taking the result data to explore methods for voice protection and be valuable for clinical diagnose and treatment. Method:Three hundred and fifth-three patients with thyroid papillary carcinoma without preoperative vocal dysfunction were treated with total thyroidectomy and single or bilateral central cervical lymph node dissection. At preoperative and the third day postoperative, videostroboscopic, acoustic analysis, voice handicap index 10(VHI-10)are measured. Result: At the third day postoperative, 294 (83.29%)patients have voice symptoms,the most common voice disorder is hoarseness in 105 cases (35.71%),phonasthenia in 78 cases(26.53%),unable speak louderly in 53 cases (18.03%), unable speak high-pitch in 24 cases (8.16%), unable speak low-pitch in 29 cases (9.86%), pronunciation leakage in 5 cases (1.70%). Videostroboscopic examinations are normal in all patients at the third day postoperative. The total score of VHI-10, Physiology(P), Emotion(E) dimensions in VHI-10 between preoperative and the third day postoperative are statistically significant (P<0.05). For male patients, the acoustic analysis (fundamental frequency, Harmonicto Noise Ratio, Shimmer and Maximum phonation time) are statistically significant between preoperative and the third day postoperative (P<0.05). For female patients, acoustic analysis (fundamental frequency, Harmonicto Noise Ratio, Shimmer, Jitter and Maximum phonation time) are statistically significant between preoperative and the third day postoperative (P<0.05). Conclusion:These patients who underwent total thyroidectomy with bilateral or unilateral central partment lymph node dissection may develop voice complications even their recurrent laryngealnerve be undamaged during the surgery. Changes in surgery and voice may cause changes in the patient's psychology, suggesting that clinicians need to have adequate communication between doctors and patients before surgery, pay attention to the patient's voice quality and psychological changes, and give positive intervention.

Abstract
PURPOSE Pyrotinib, an irreversible pan-ErbB inhibitor, showed promising antitumor activity and acceptable tolerability in a phase I trial. We assessed the efficacy and tolerability of pyrotinib versus lapatinib, both in combination with capecitabine, in women with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in an open-label, multicenter, randomized phase II study. PATIENTS AND METHODS Chinese patients with HER2-positive relapsed or metastatic breast cancer previously treated with taxanes, anthracyclines, and/or trastuzumab were assigned (1:1) to receive 400 mg pyrotinib or lapatinib 1,250 mg orally once per day for 21-day cycles in combination with capecitabine (1,000 mg/m2 orally twice per day on days 1 to 14). The primary end point was investigator-assessed overall response rate per Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. RESULTS Between May 29, 2015, and March 15, 2016, 128 eligible patients were randomly assigned to the pyrotinib (n = 65) or lapatinib (n = 63) treatment groups. The overall response rate was 78.5% (95% CI, 68.5% to 88.5%) with pyrotinib and 57.1% (95% CI, 44.9% to 69.4%) with lapatinib (treatment difference, 21.3%; 95% CI, 4.0% to 38.7%; P = .01). The median progression-free survival was 18.1 months (95% CI, 13.9 months to not reached) with pyrotinib and 7.0 months (95% CI, 5.6 to 9.8 months) with lapatinib (adjusted hazard ratio, 0.36; 95% CI, 0.23 to 0.58; P < .001). The most frequent grade 3 to 4 adverse events were hand-foot syndrome in 16 of 65 patients (24.6%) in the pyrotinib group versus 13 of 63 (20.6%) in the lapatinib group; diarrhea in 10 patients (15.4%) versus three patients (4.8%), respectively; and decreased neutrophil count in six patients (9.2%) versus two patients (3.2%), respectively. CONCLUSION In women with HER2-positive metastatic breast cancer previously treated with taxanes, anthracyclines, and/or trastuzumab, pyrotinib plus capecitabine yielded statistically significant better overall response rate and progression-free survival than lapatinib plus capecitabine in this randomized phase II trial.

Abstract
PURPOSE This phase I study assessed the safety, tolerability, MTD, pharmacokinetics, antitumor activity, and predictive biomarkers of pyrotinib, an irreversible pan-ErbB inhibitor, in combination with capecitabine in patients with HER2-positive metastatic breast cancer (MBC). PATIENTS AND METHODS Patients received oral pyrotinib 160 mg, 240 mg, 320 mg, or 400 mg once daily continually plus capecitabine 1,000 mg/m2 twice daily on days 1 to 14 of a 21-day cycle. Pharmacokinetic blood samples were collected on days 1 and 14. Next-generation sequencing was performed on circulating tumor DNA to probe for predictive biomarkers. RESULTS A total of 28 patients were enrolled, 22 patients were treated at the two top-level doses. Among 17 (60.7%) trastuzumab-pretreated patients, 11 received trastuzumab for metastatic disease and 6 received adjuvant trastuzumab. No dose-limited toxicity was observed. Grade 3 treatment-related adverse events (AE) occurred in 12 (42.9%) patients; anemia (14.3%) and diarrhea (10.7%) were the most common grade 3 AEs. The overall response rate (ORR) was 78.6% [95% confidence interval (CI): 59.0%-91.7%], and the clinical benefit rate was 85.7% (95% CI: 67.3%-96.0%). The median progression-free survival (PFS) was 22.1 months (95% CI: 9.0-26.2 months). ORR was 70.6% (12/17) in trastuzumab-pretreated patients and 90.9% (10/11) in trastuzumab-naïve patients. Analysis of all genetic alterations in HER2-related signaling network in baseline blood samples suggested that multiple genetic alterations were significantly associated with poorer PFS compared with none or one genetic alteration (median, 16.8 vs. 29.9 months, P = 0.006). CONCLUSIONS In a population largely naïve to HER2-targeted therapy, pyrotinib in combination with capecitabine was well-tolerated and demonstrates promising antitumor activity in patients with HER2-positive MBC.

Abstract
9089 Background: HER2 exon 20 mutation is a well-known oncogenic driver in non-small cell lung cancer (NSCLC) and its testing is recommended by NCCN guidelines for NSCLC patients. However, up to now, there has been no approved targeted therapy for this patient population. Pyrotinib is an oral, irreversible pan-Her tyrosine kinase inhibitor (TKI) against HER1, HER2 and HER4, which, combined with chemotherapy, has recently been approved in China for HER2 positive advanced breast cancer. Methods: Stage IIIB or IV NSCLC patients with HER2 exon 20 mutation (confirmed in a central lab) and previously treated with at least one platinum-based chemotherapy were enrolled in this open-label, multi-center, single-arm phase II study. Patients with active brain metastases or prior use of HER2 TKI agents were excluded. Eligible patients received pyrotinib 400 mg once daily until disease progression, intolerable toxicity or withdrawal of consent. The primary endpoint was objective response rate (ORR) according to RECIST 1.1. Secondary endpoints included safety, progression-free survival (PFS), time to disease progression (TTP), duration of response (DOR) and overall survival (OS). This trial is registered on ClinicalTrials.gov (NCT02834936). Results: Between October 20, 2016 and December 10, 2018, 60 patients (33 female, 27 male) were enrolled. The median age was 57 years (range: 40, 72). A majority were stage IV patients (95%). Over 58% of patients have been treated with two or more prior chemotherapy regimens. As of Jan 21, 2019, the ORR as evaluated by investigators was 31.7% (95% CI 20.3%, 45.0%). Median DOR was 7.0 months (95% CI 5.5, 11.0) and median PFS was 6.8 months (95% CI 4.1, 8.3). 26.7% patients reported treatment-related grade 3 AEs. Diarrhea (20.0%) was the only treatment-related grade 3 AE that occurred in ≥ 2 patients. Treatment-related grade 4 AE was reported in 1 subject (elevated gamma-glutamyl transferase). The anti-tumor activities of pyrotinib was shown in various mutation types. Conclusions: Pyrotinib as a single agent demonstrated promising anti-tumor activity and acceptable safety profile in heavily pretreated HER2 mutant NSCLC patients. Clinical trial information: NCT02834936.

Abstract
4031 Background: Capecitabine plus oxaliplatin (CAPOX) is one of the standard first-line treatments for advanced or metastatic gastric cancer. Camrelizumab (SHR-1210, an anti–PD-1 antibody) shows promising anti-tumor activity in patients (pts) with advanced or metastatic gastric or gastroesophageal junction (G/GEJ) cancer. Camrelizumab combined with CAPOX for untreated G/GEJ cancer was assessed as a part of an ongoing multicenter, open-label phase 2 trial (cohort 1), and encouraging preliminary results were reported. Here, we present the updated safety and efficacy data. Methods: In this cohort, systemic treatment naïve pts with HER2– advanced or metastatic G/GEJ adenocarcinoma were given camrelizumab 200 mg on Day 1, capecitabine 1000 mg/m2 bid on Days 1–14 and oxaliplatin 130 mg/m2 on Day 1 of each 21-day-cycle for 4 to 6 cycles followed by camrelizumab 200 mg every 3 weeks plus apatinib 375 mg qd until disease progression or intolerable toxicity. The primary endpoint was objective response rate. Results: At data cutoff (Jan 20, 2019), 43 of the 48 enrolled pts were evaluable. Partial response was observed in 28 pts (65%), and 19 (44%) were confirmed. Stable disease in 14 pts and progressive disease in 10 pts were reported. Median estimates for duration of response and progression-free survival were not reached. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 9 pts (21%), included neutropenia, diarrhea, rash and elevated ALT, whereas none of the TRAEs was fatal. Ten pts without progression after 4–6 cycles of camrelizumab and CAPOX combination therapy all received camrelizumab plus apatinib as sequential therapy, and no new safety signals were observed. Conclusions: The updated results confirmed that camrelizumab plus CAPOX followed by camrelizumab plus apatinib was well tolerated with noteworthy responses as first-line therapy in advanced or metastatic G/GEJ cancer pts. Expansion of this cohort in a phase 3 study are under way. Clinical trial information: NCT03472365.

Abstract
1001 Background: Pyrotinib, an irreversible pan-ErbB receptor tyrosine kinase inhibitor, showed promising anti-tumour activity and acceptable tolerability in patients with HER2+ metastatic breast cancer (MBC) in phase 1/2 trials. Methods: This double-blinded, multicentre, randomised phase 3 trial was conducted in Chinese patients with HER2+ MBC previously treated with taxanes and trastuzumab. Patients were randomly assigned (2:1) to receive 400 mg pyrotinib or placebo orally once daily for 21-day cycles in combination with capecitabine (1000 mg/m2 orally twice daily on days 1–14). The primary endpoint (IRC-assessed progression free survival [PFS]) was assessed in patients who received ≥1 dose of study treatment. Patients whose disease progressed on placebo plus capecitabine received subsequent single agent pyrotinib. Results: Between July, 2016 and November, 2017, 279 patients were randomised to pyrotinib plus capecitabine (n = 185) or placebo plus capecitabine (n = 94) arms. The median PFS was 11.1 months (95% CI 9.66, 16.53) in the pyrotinib plus capecitabine arm and 4.1 months (95% CI 2.79, 4.17) in the placebo plus capecitabine arm. seventy-one patients in placebo plus capecitabine arm received subsequent pyrotinib, showing single-agent response rate of 38.0% (95%CI 26.7%, 49.3%) and median PFS of 5.5 months (95% CI 4.07, 6.90). The most frequent (≥5%) treatment-related ≥ grade 3 adverse events were diarrhoea (30.8% vs 12.8% ) and hand-foot syndrome (15.7% vs 5.3%). Conclusions: In women with HER2+ MBC previously treated with taxanes and trastuzumab, pyrotinib plus capecitabine yield statistically significant better PFS. Pyrotinib monotherapy showed anti-tumour activity. Clinical trial information: NCT02973737. [Table: see text]

Abstract
4074 Background: Advanced hepatocellular carcinoma (HCC) and biliary tract cancer (BTC) patients (pts) have very limited treatment options. Considering the immunogenic effects of oxaliplatin, combination of camrelizumab with oxaliplatin-based chemotherapy might bring a better clinical benefit. Methods: That was an ongoing single-arm, multicenter phase 2 trial. Advanced HCC or BTC pts naive to systemic treatment were given camrelizumab (3 mg/kg i.v., every 2 weeks) plus typical FOLFOX4 (infusional fluorouracil, leucovorin and oxaliplatin) or GEMOX (gemcitabine and oxaliplatin) regimen. Primary endpoints were confirmed objective response rate (ORR) per RECIST v1.1 and safety per CTC AE 4.03. Results: From Apr 27, 2017 to Oct 31, 2018, 34 Chinese HCC and 47 BTC pts were treated, in which 27 (79.4%) HCC and 17 (36.2%) BTC pts were HBV-infected. In the 34 evaluable HCC pts, confirmed ORR was 26.5% and disease control rate (DCR) was 79.4%. Median time to response (TTR) was 2.0 mo (range 1.5–5.7). Six of the 9 responses were still ongoing, and median duration of response (DoR) was not reached (range 3.3–11.5+ mo). Median progression-free survival (PFS) was 5.5 mo. At data cutoff, 61.7% BTC pts were still receiving study drug. In the 43 evaluable BTC pts, with a median duration of exposure of 2.9 mo, confirmed ORR was 7.0% and DCR was 67.4%. Median TTR was 1.9 mo (range 1.8–2.1). Median DoR was 5.3 mo (range 3.7–7.0). Median PFS was not reached yet. Median estimates for overall survival in both HCC and BTC were also not reached. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 85.3% of HCC and 57.4% of BTC pts, most commonly neutrophil count decreased (HCC: 55.9%; BTC: 29.8%), white blood cell decreased (HCC: 38.2%; BTC: 21.3%), platelet count decreased (HCC: 17.6%; BTC: 12.8%), and anaphylaxis (BTC: 19.1%). Only one BTC pt stopped treatment due to a TRAE (recurrent Grade 2 anemia related to FOLFOX4). Grade ≥3 immune-related AEs occurred only in 5.9% of HCC (lipase increased) and 3.8% of BTC pts (anaphylaxis). Conclusions: Camrelizumab plus FOLFOX4 or GEMOX chemotherapy was tolerable and might offer a new promising choice for advanced HCC and BTC pts. Clinical trial information: NCT03092895.

Abstract
The aim of this study was to assess the effectiveness of low-level laser therapy (LLLT) for pain management after root canal treatment or retreatment. An electronic search for randomized controlled trials was conducted prior to November 2018, through PubMed, EMBASE, the Cochrane library (CENTRAL), and Web of Science. After filtering, seven articles were included, five related to root canal therapy (RCT) and two related to root canal retreatment (RCR). Six of the included studies presented a moderate risk of bias and a one low risk of bias, based on the Cochrane tool of risk of bias evaluation. The laser treatment included diode laser and indium-gallium-aluminum laser. LLLT was compared with placebo, blank, and ibuprofen treatment. Clinical outcome variables included the prevalence of pain, pain intensity, and need for analgesics after treatment. Three studies showed LLLT could reduce the prevalence of pain significantly after RCT or RCR. Although the effect of LLLT on pain intensity varied at different observation time points and among different studies, most of them found patients had lower pain intensity in the LLLT group. Of the three studies that assessed the need for analgesics after treatment, two studies showed significant benefits. Based on the current evidence, the use of LLLT for pain control in postendodontic therapy may be promising. However, solid conclusions should not be drawn definitely, given that more high-quality randomized controlled trials are required to further evaluate the efficacy of LLLT for pain management after RCT and RCR.

Abstract
AIMS To evaluate whether decoloured cell-free supernatant of Lysobacter enzymogenes C3 can decrease paper bioreceptivity to fungal attack. METHODS AND RESULTS To prepare colourless C3 supernatant, single-factor design and uniform design were applied. The optimum conditions with high decolouration degree and low antifungal activity loss were achieved as follows: carbon granule content 1·6% (M/V), temperature 27°C, decolouring time 1·2 h and pH 8·0. An agar plate bioassay was used to assess the antifungal activity of the decoloured supernatant against the fungal isolates obtained from contaminated books, and strong suppression was observed. Small-sacle laboratory test was further introduced, in which common book papers were artificially inoculated with the fungal isolates, and then sprayed uniformly with decoloured supernatant or water. The results showed that, after treatment, the paper showed a significantly low extent of fungal colonization and high tensile strength, and maintained the same colour before and after treatment. CONCLUSION These results suggest that the decoloured C3 supernatant inhibits fungal growth on types of paper commonly used in books. SIGNIFICANCE AND IMPACT OF THE STUDY Decoloured C3 supernatant could be used as a preventive agent to protect books and other paper-based items against fungal growth.

Abstract
NLRP3 inflammasome has been reported to be associated with inflammatory bowel disease including colitis due to its potential ability to induce IL-1β secretion. Emerging studies have demonstrated that Genistein, a major isoflavone, has potential anti-inflammatory effects in murine model colitis. However, its anti-inflammatory mechanism remains unclear. The effects of Genistein in dextran sulfate sodium (DSS)-induced murine colitis via targeting NLRP3 inflammasome was investigated in this study. Also, the mechanisms of protective action of Genistein in DSS-induced colitis may relate to TGR5 signaling. Genistein treatment not only remarkably attenuated loss of body weight and shortening of colon length but also significantly reduced inflammatory cells infiltration and pro-inflammatory mediator production in serum and colon. Moreover, Genistein treatment down-regulated production of caspase-1 and IL-1β and increased intracellular cAMP level, which were similar to the treatment for INT-777, a semi-synthetic TGR5 agonist, in phorbol myristate acetate (PMA)-differentiated monocytic THP-1 cells and U937 cells. These protective effects of Genistein might be attributed by ubiquination of NLRP3 which was induced due to interaction of cAMP with NLRP3. Furthermore, the effects of Genistein on NLRP3 inflammasome disappeared in TGR5-silenced U937 cells. In conclusion, our study unveils that Genistein was able to inhibit NLRP3 inflammasome via TGR5-cAMP signaling in macrophages. It therefore might be a potential effective drug for inflammatory bowel diseases.

Abstract
BACKGROUND AND PURPOSE Tirofiban is used off-label in clinical practice for acute ischaemic stroke (AIS). However, it is unknown whether tirofiban increases the bleeding risk or improves the outcome of endovascular treatment (EVT) in AIS. This study evaluated the efficacy and safety of tirofiban in combination with EVT for AIS. METHODS Consecutive patients with AIS receiving EVT were included in the prospective stroke registry from 2015 to 2018. The efficacy outcomes were modified Rankin Scale (mRS) score at 3 months and National Institutes of Health Stroke Scale (NIHSS) score at 24 h. The safety outcomes were symptomatic intracerebral hemorrhage (sICH), any in-hospital intracerebral hemorrhage, in-hospital death and 3-month death. RESULTS Of 211 patients, 82 (38.9%) received tirofiban. A total of 39 (48.1%) with tirofiban and 44 (36.1%) without tirofiban had mRS score 0-2 [adjusted odds ratio (OR), 2.41; 95% confidence interval (CI), 1.11-5.23, P = 0.026]. NIHSS score at 24 h was lower in the tirofiban group (9.5 vs. 12.0, adjusted P = 0.032). Five (6.1%) patients with tirofiban and 16 (12.4%) without tirofiban had sICH (adjusted OR, 0.54; 95% CI, 0.16-1.83, P = 0.32). In-hospital intracerebral hemorrhage occurred in 10 (12.2%) patients with tirofiban and 41 (31.8%) without tirofiban (adjusted OR, 0.32; 95% CI, 0.13-0.76, P = 0.01). In-hospital death occurred in 7 (8.5%) patients with tirofiban and 16 (12.4%) without tirofiban (adjusted OR, 0.69; 95% CI, 0.22-2.13, P = 0.52). A total of 13 (15.9%) patients with tirofiban and 22 (17.1%) without tirofiban were dead at 3 months (adjusted OR, 0.98; 95% CI, 0.40-2.40, P = 0.96). CONCLUSIONS Tirofiban in combination with EVT was associated with a lower mRS score at 3 months and NIHSS score at 24 h. It was not associated with a higher rate of sICH, in-hospital death and death at 3 months.

Abstract
Objective: To optimize delivery of gadolinium-diethylenetriamine pentaacetic acid(Gd-DTPA) at the posterior upper point on tympanic medial wall and heavily T2-weighted 3-dimensional fluid-attenuated inversion recovery (hT2W-3D-FLAIR) sequence, and to implement the technique of detecting endolymphatic hydrops using gadolinium-enhancement MRI. Methods: Thirteen patients with periphery vertigo, who visited Department of Otorhinolaryngology Head and Neck Surgery, Shanghai Changhai Hospital during June and December of 2017, were enrolled in the study.0.10-0.20 ml of Gd-DTPA in various dilutions (10, 20, and 40-fold) were delivered at the posterior upper point on tympanic medial wall using a soft-tipped tympanic suction and drug-spraying needle through an artificially perforated tympanic membrane. Inner ear MRI was performed at 8, 24 h after Gd-DTPA administration using a 3T MR machine in combination with a 20-channel Tim 4G head/neck coil and the sequence of hT2W-3D-FLAIR to detect the gadolinium-enhancement signal within the inner ear and possible endolymphatic hydrops. The scanning time was either 8 min 35 s or 15 min 11 s. Results: Efficient inner ear uptake of Gd-DTPA was detected and induced high signal to noise ratio of MRI in patients receiving targeted delivery of 0.15-0.20 ml of 10-fold diluted contrast agent at the posterior upper point on tympanic medial wall. At 8 h after delivery, significant uptake was detected in the scala tympani and vestibuli of hook region and basal turn of the cochlea, and perilymhatic compartment of the vestibule. At 24 h after delivery, the distribution of Gd-DTPA became homogenous in each turn of the cochlea and perilymphatic compartment of the vestibule. However, obvious individual variance existed in the inner ear uptake when 0.10 ml of 40-fold diluted Gd-DTPA was delivered. Efficient inner ear uptake and high quality images that generated in patients receiving 0.10, 0.15, and 0.20 ml of 20-fold Gd-DTPA demonstrated endolymphatic hydrops with minor individual variance. There was insignificant difference in the enhancement signal of inner ear between 0.15 and 0.10 ml groups when Gd-DTPA was diluted at 20-fold except for the signal of semicircular canal of 0.15 ml group (190.00±53.95 vs 165.50±42.13, t=2.61, P<0.05). There was insignificant difference in the image quality between 8 min 35 s and 15 min 11 s canning time. Various degrees of endolymphatic hydrops were detected in 7 cochleae and 11 vestibule, and both simultaneous cochlear and vestibular endolymphatic hydrops were detected in 4 ears. Cochlear endolymphatic hydrops was detected in all the 3 patients with definite Meniere's disease, and 2 of them had combined cochlear and vestibular endolymphatic hydrops. Endolymphatic hydrops was not detected in patients with possible Meniere's disease nor with symptoms of superior semicircular canal dehiscence. Conclusion: Targeted delivery of 0.10 ml with 20-fold diluted Gd-DTPA (total dosage of 5 μmol) at the posterior upper point on tympanic medial wall in combination with 8 min 35 s scanning time hT2W-3D-FLAIR sequence for inner ear MRI in a 3T MR machine is a clinically practical method to detect endolymphatic hydrops, and reduce the requirement for MRI hardware.

Abstract
PURPOSE Flap endonuclease 1 (FEN1) is up-regulated by estrogen (17β-estradiol, E2) and related to cisplatin resistance of human breast cancer cells. Letrozole, an aromatase inhibitor, suppresses the change of testosterone into estrogen and is frequently used to treat breast cancer. However, the effects of letrozole on FEN1 expression and cisplatin sensitivity in breast cancer cells overexpressing aromatase have not been revealed. METHODS The expression of FEN1 and the proteins in ERK/Elk-1 signaling were evaluated by RT-PCR and Western blot. Cisplatin sensitivity was explored through CCK-8 and flow cytometry analysis, respectively. FEN1 siRNAs and FEN1 expression plasmid were transfected into cells to down-regulate or up-regulate FEN1 expression. The promotor activity of FEN1 was detected using luciferase reporter assay. RESULTS FEN1 down-regulation improved cisplatin sensitivity of breast cancer cells overexpressing aromatase. Letrozole down-regulated FEN1 expression and increased cisplatin sensitivity. The sensitizing effect of letrozole to cisplatin was dependent on FEN1 down-regulation. FEN1 overexpression could block the sensitizing effect of letrozole to cisplatin. Testosterone up-regulated the promotor activity, protein expression of FEN1, and phosphorylation of ERK/Elk-1, which could be eliminated by both letrozole and MEK1/2 inhibitor U0126. Letrozole down-regulated FEN1 expression in an ERK/Elk-1-dependent manner. CONCLUSIONS Our findings clearly demonstrate that letrozole improves cisplatin sensitivity of breast cancer cells overexpressing aromatase via down-regulation of FEN1 and suggest that a combined use of letrozole and cisplatin may be a potential treatment protocol for relieving cisplatin resistance in human breast cancer.

Abstract
Esophageal stricture is a major problem for patients with large superficial esophageal squamous cell neoplasms (SESCNs) after endoscopic submucosal dissection (ESD). Although many measures could be used as prophylaxis for post-ESD strictures, a well-accepted method has not yet been established. We propose using a triamcinolone-soaked polyglycolic acid sheet plus fully covered metal stent (TS-PGA+FCMS) as a novel method to prevent stricture formation after large esophageal ESD. From June 2016 to May 2017, nine patients with SESCNs (≥3/4 of the esophageal circumference) who underwent TS-PGA+FCMS placement immediately after ESD and did not require additional surgical resection were enrolled in this case series. All stents were removed 4-6 weeks post-ESD. The sizes of mucosal defects in 9 patients were 3/4 (n = 1), 4/5 (n = 2), 1/1 (n = 6). The average size of resection was 90.0 mm (range: 60-140 mm). The incidence of stricture was 33.3% (3/9) of patients. No stricture occurred in 3 patients with noncircumferential resection, while stricture occurred in 50% (3/6) patients with circumferential resection. The median number of EBD sessions was 4 (range: 3-4 sessions). No adverse events or recurrences were observed during the median follow-up period of 15.2 months (range: 12-22 months). The TS-PGA+FCMS method is safe and may decrease the incidence of esophageal stricture and the number of EBD sessions after large esophageal ESD.

Abstract
Distributed ditches and ponds in agricultural landscapes can retain agricultural pollutants (such as nutrients and pesticides) like wetlands while facilitating crop field drainage. Their complex hydraulic conditions affect pollutant transport and degradation processes, but the existing lump-sum method for estimating pollutant removal treats the total area simply as one unit without considering their specific hydraulic conditions (HCs). In this paper we proposed an analytical method for evaluating pollutant removal efficiencies of distributed ditches and ponds by considering their different HCs explicitly. A realization factor (RF) was used to compare pollutant removal rates with and without considering specific HCs. Application of the method was demonstrated with a case study based on field investigations in an intensively farmed area in southeastern China. The total area of ditches and ponds accounts for 15% of drained crop fields; and the calculated RFs were 0.70-0.84% for various removal rate constants. The difference was mainly caused by the uneven distribution of ditches and ponds along different drainage paths. For pollutants with small values of removal rate constants, the calculated concentration reductions along different flow paths were proportional to their wetland sizes, making the pollutant removal as area limited. For pollutants with larger values of removal rate constant, however, the calculated pollutant removal became concentration limited when the wetland to farmland area ratio was high. Large ponds and ditches were major contributors (85-94%) of pollutant removal in the whole system, while the field ditches contributed to less than 10% of the total removal due to their small dimension and shallow water depth. The distributed nature of ditches and ponds poses some inherent limitations to their water quality functions due to variable hydraulic conditions; understanding such underlying constraints may help guide proper evaluation and conservation of the existing ditches and ponds in agricultural landscapes.

Abstract
Background The role of systemic inflammation-based markers remains uncertain in advanced or metastatic neuroendocrine tumours (nets). Methods Systemic inflammatory factors, such as levels of circulating white blood cells and other blood components, were combined to yield inflammation-based prognostic scores [high-sensitivity inflammation-based Glasgow prognostic score (hsgps), neutrophil:lymphocyte ratio (nlr), platelet:lymphocyte ratio (plr), high-sensitivity inflammation-based prognostic index (hspi), and prognostic nutritional index (pni)], whose individual values as prognostic markers were retrospectively determined. Univariate and multivariate analyses were used to examine the association of inflammatory markers with overall survival (os). Results The study included 135 patients. Univariate analysis revealed that elevated white blood cell count, elevated neutrophil count, low serum albumin, elevated high-sensitivity C-reactive protein, and elevated hspi, hsgps, and nlr scores were significantly associated with worse os. Multivariate analyses demonstrated that, apart from pathology grade and original site of the tumour, elevated hspi (p = 0.004) was an independent prognostic factor for worse os. Conclusions In the present study, elevated pretreatment hspi was observed to be an independent predictor of shorter os in patients with inoperable advanced or metastatic net. The hspi might thus provide additional guidance for therapeutic decision-making in such patients.

Abstract
Multidetector computed tomography has been the benchmark for visualizing bony changes of the ear, but has recently been challenged by cone-beam computed tomography. In both methods, all inner ear bony structures can be visualized satisfactorily with 2D or 3D imaging. Both methods produce ionizing radiation and induce adverse health effects, especially among children. In 3T magnetic resonance imaging, the soft tissue can be imaged accurately. Use of gadolinium chelate (GdC) as a contrast agent allows the partition of fluid spaces to be visualized, such as the bulging of basilar and Reissner's membranes. Both intravenous and intratympanic administration of GdC has been used. The development of positive endolymph imaging method, which visualizes endolymph as a bright signal, and the use of image subtraction seems to allow more easily interpretable images. This long-awaited possibility of diagnosing endolymphatic hydrops in living human subjects has enabled the definition of Hydropic Ear Disease, encompassing typical Meniere's disease as well as its monosymptomatic variants and secondary conditions of endolymphatic hydrops. The next challenge in imaging of the temporal bone is to perform imaging at the cellular and molecular levels. This chapter provides an overview of current temporal bone imaging methods and a review of emerging concepts in temporal bone imaging technology.

Abstract
There are two production clusters co-existed in the Institute of High Energy Physics (IHEP). One is a High Throughput Computing (HTC) cluster with HTCondor as the workload manager, the other is a High Performance Computing (HPC) cluster with Slurm as the workload manager. The resources of the HTCondor cluster are funded by multiple experiments, and the resource utilization reached more than 90% by adopting a dynamic resource share mechanism. Nevertheless, there is a bottleneck if more resources are requested by multiple experiments at the same moment. On the other hand, parallel jobs running on the Slurm cluster reflect some specific attributes, such as high degree of parallelism, low quantity and long wall time. Such attributes make it easy to generate free resource slots which are suitable for jobs from the HTCondor cluster. As a result, if there is a mechanism to schedule jobs from the HTCon-dor cluster to the Slurm cluster transparently, it would improve the resource utilization of the Slurm cluster, and reduce job queue time for the HTCondor cluster. In this proceeding, we present three methods to migrate HTCondor jobs to the Slurm cluster, and concluded that HTCondor-C is more preferred. Furthermore, because design philosophy and application scenes are di↵erent between HTCondor and Slurm, some issues and possible solutions related with job scheduling are presented.

Abstract
Objective: To explore the changes of helper T lymphocytes 17 (Th17) and regulatory T lymphocytes (Tregs) in peripheral blood of patients with extensive burn at early stage in August 2nd aluminum dust explosion accident in Kunshan factory (hereinafter referred to as Kunshan explosion accident) and the significance. Methods: Twenty patients with extensive burn in Kunshan explosion accident admitted to our department of burns and plastic surgery were enrolled in burn group, and 10 healthy adult volunteers with no history of smoking were enrolled in healthy control group. Five mL of peripheral venous blood samples were collected from patients in burn group at admission (≤post injury hour 6, PIH 6) and PIH 24, and on post injury day (PID) 7, and from volunteers in healthy control group respectively. The percentages of CD64(+) T lymphocytes, human leukocyte antigen-DR positive (HLA-DR(+) ) T lymphocytes, CD3(+) CD8(-) Th17, and CD4(+) CD25(+) Tregs in peripheral blood T lymphocytes were determined by flow cytometer. Results: (1) The percentages of CD64(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(2.35±0.32)% and (4.02±0.15)%] were higher than (0.67±0.11)% of healthy volunteers in healthy control group. The percentage of CD64(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group on PID 7 [(0.39±0.25)% ] was lower than that of healthy volunteers in healthy control group. The percentages of HLA-DR(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(54±18)% and (72±17)%] were higher than (38±14)% of healthy volunteers in healthy control group. The percentage of HLA-DR(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group on PID 7 [(28±15)% ] was lower than that of healthy volunteers in healthy control group. (2) The percentages of CD3(+) CD8(-)Th17 in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(4.21±0.46)% and (7.38±0.39)%] were higher than (0.98±0.09)% of healthy volunteers in healthy control group. The percentage of CD3(+) CD8(-)Th17 in peripheral blood T lymphocytes of patients in burn group on PID 7 [(0.81±0.05)% ] was lower than that of healthy volunteers in healthy control group. (3) The percentages of CD4(+) CD25(+) Tregs in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24, and on PID 7 [(1.78±0.26)%, (1.26±0.37)%, and (0.38±0.03)%] were lower than (3.24±0.52)% of healthy volunteers in healthy control group. Conclusions: The percentage of Th17 in peripheral blood T lymphocytes of patients with extensive burn at early stage in Kunshan explosion accident increased at first and then decreased compared with that of healthy volunteers, indicating that the patients' immune function increased first and then weakened. The percentages of Tregs in peripheral blood T lymphocytes at each time point were lower than the percentage of healthy volunteers, indicating that the patients' immunomodulation gradually weakened after extensive burns.

Abstract
Objective:Anti-reflux medications or botulinum toxin A injections are the main current therapies for the definite vocal process granuloma. This studies is focusing on comparing the effects of proton pump inhibitors plus prokinetic agents with botulinum toxin A injections on vocal process granuloma. Method:Adult patients in our outpatient department (from December 2014 to June 2016) complaining of trachyphonia and/or abnormal pharyngeal sensations who were found to have contact granulomas (38 cases) were included. Patients were divided into two groups according to the treatment selected by themselves: esomeprazole with mosapride citrate (n=28) or botulinum toxin A injection (n=20). The reflux symptom index and reflux finding score determined by electronic fibrolaryngoscopy were utilized to assess efficacy. Result:There was no statistical difference on age, sex and reflux symptom index and reflux finding score before treatment between the two groups. Total effective rate in the esomeprazole with mosapride citrate group and the botulinum toxin A group were 96.43% and 45.00%, separately. The recorded symptoms after therapy resolved with a statistically significant improvement in the esomeprazole with mosapride citrate group. Conclusion:Combined proton pump inhibitor plus prokinetic drug therapy plays a significant role in the treatment of vocal process granulomas.

Abstract
PURPOSE This study assessed the safety and efficacy of SHR-1210 (anti-PD-1 antibody) and apatinib (VEGFR2 inhibitor) as combination therapy in patients with advanced hepatocellular carcinoma (HCC), gastric, or esophagogastric junction cancer (GC/EGJC). PATIENTS AND METHODS This was an open-label, dose-escalation (phase Ia) and expansion study (phase Ib). In phase Ia, patients (n = 15) received SHR-1210 200 mg every 2 weeks and apatinib 125-500 mg once daily until unacceptable toxicity or disease progression. In phase Ib, patients (n = 28) received apatinib at the phase Ia-identified recommended phase II dose (RP2D) plus SHR-1210. The primary objectives were safety and tolerability and RP2D determination. RESULTS At data cutoff, 43 patients were enrolled. In phase Ia, four dose-limiting toxicity events were observed (26.7%): one grade 3 lipase elevation (6.7%) in the apatinib 250 mg cohort and three grade 3 pneumonitis events (20%) in the apatinib 500 mg cohort. The maximum tolerated RP2D for apatinib was 250 mg. Of the 33 patients treated with the R2PD combination, 20 (60.6%) experienced a grade ≥3 treatment-related adverse event; adverse events in ≥10% of patients were hypertension (15.2%) and increased aspartate aminotransferase (15.2%). The objective response rate in 39 evaluable patients was 30.8% (95% CI: 17.0%-47.6%). Eight of 16 evaluable HCC patients achieved a partial response (50.0%, 95% CI: 24.7%-75.4%). CONCLUSIONS SHR-1210 and apatinib combination therapy demonstrated manageable toxicity in patients with HCC and GC/EGJC at recommended single-agent doses of both drugs. The RP2D for apatinib as combination therapy was 250 mg, which showed encouraging clinical activity in patients with advanced HCC.

Abstract
Increased knowledge of the immune response of the intestine, a physiologically critical organ involved in absorption, secretion and homeostasis in a non-sterile environment, is needed to better understand the mechanisms involved in the induction of long-lasting immunity and, subsequently, the development of efficacious gastrointestinal immunization approaches. To this end, analysis of isolated gut cells will give an insight into the cell types present and their immune capability. Hence, in this study we first optimised a method for salmonid gut leucocyte isolation and characterised the cells on the basis of their expression of a range of selected cell markers associated with T & B cells and dendritic cells. The GALT leucocytes were then stimulated with a variety of PAMPs, recombinant cytokines and PHA, as a means to help characterise the diversity of the immune repertoire present in such cells. The stimulants tested were designed to examine the nature of the antibacterial, antiviral and T cell type responses in the cells (at the transcript level) using a panel of genes relevant to innate and adaptive immunity. The results showed distinct responses to the stimulants, with a clear delineation seen between the stimulant used (eg viral or bacterial PAMP) and the pathway elicited. The changes in the expression patterns of the immune genes in these cells indicates that the salmonid intestine contains a good repertoire of competent immune cells able to respond to different pathogen types. Such information may aid the development of efficient priming by oral vaccination in salmonids.

Abstract
Previous studies reported that Ginsenoside Rd (Rd) had anti-inflammatory and anti-cancer effects. However, the molecular mechanism underlying the inhibition effect of Rd on colitis in mice hasn't been clarified clearly. Here, in our study, we detected the effects of Rd on dextran sulfate sodium (DSS)-induced murine colitis, and found that oral administration of Rd dose-dependently alleviated DSS-induced body weight loss, colon length shortening and colonic pathological damage with lower myeloperoxidase (MPO) and inducible nitric oxide synthase (iNOS) activities and higher glutathione level. In addition, the production of pro-inflammatory cytokines (IL-1β, TNF-a and IL-6) in both serum and colonic tissues were significantly down-regulated by Rd administration. The activation of NLRP3 inflammasome was also suppressed in Rd-treated group, resulting in reduced caspase-1 production and IL-1β secretion. In vitro, Rd remarkably inhibited NLRP3 inflammasome activation which was mostly dependent on the mitochondrial translocation of p62 and mitophagy. Importantly, Rd-driven inhibition of the NLRP3 inflammasome was significantly blocked by various autophagy inhibitors. Furthermore, upregulation of AMPK/ULK1 signaling pathway accounted for Rd-induced autophagy, which was also seen in vivo. In conclusion, our results demonstrated the function of Rd on the inhibition NLRP3 inflammasome and its potential application for the treatment of NLRP3-associated diseases.

Abstract
Type I interferons (IFN) play an important role in anti-viral responses. In teleost fish multiple genes exist, that are classified by group/subgroup. That multiple subgroups are present in Acanthopterygian fish has only become apparent recently, and 3 subgroups are now known to be expressed, including a new subgroup termed IFNh. However, the potential to express multiple IFN subgroups and their interplay is not well defined. Hence this study aims to clarify the situation and undertook the first in-depth analysis into the nature and expression of IFNc, IFNd and IFNh in the perciform fish, meagre. Constitutive expression was analysed initially during larval development and in adult tissues (gills, mid-gut, head kidney, spleen). During early ontogeny IFNc was the highest expressed IFN, and this was also the case in adult tissues with the exception of gills where IFNd was highest. However, comparison between tissues for individual isoforms showed that spleen had high transcript levels of all three IFNs, IFNd/IFNh were also highly expressed in gills. The expression of each sub-group was increased significantly in the four tissues following injection of poly I:C, however, this increase was only seen in the mid-gut for IFNh. Following in vitro stimulation with poly I:C again all three isoforms were upregulated, although with differences in kinetics and the cell source used. For example, early induction was seen for IFNc/IFNh in gill cells, IFNd/IFNh in splenocytes and all three isoforms in head kidney cells. Induction was sustained in splenocytes and head kidney cells, but in gut cells only a late induction was seen. These results demonstrate a complex pattern of regulation between the different IFN isoforms present in meagre and highlights potential sub-functionalisation of these IFN subgroups during perciform anti-viral responses.

Abstract
A case of Crouzon syndrome coupled with OSAHS and congenital heart disease in our hospital was reported. The patient who was a 2 years and 7 months old boy, was admitted in our hospital for repetitive sore throat, snoring with mouth breathing during sleep for more than 2 years and been found with some typical defect of Crouzon syndrome during physical examination. Half a year ago the boy underwent ventricular septal defect closure surgery. PSG shows severe apnea hypopnea and low ventilation existed. Under general anesthesia, the patient accepted bilateral tonsillectomy and adenoidectomy but dyspnea occurred after post-operative extubation till 2 days later the boy can breathe by himself. The follow-up at 6 months and 1 year revealed that the patient did not have snoring or mouth breathing during sleep. For this kind of case, we should assess detailed pre-operation and observe carefully post-operation so as to reduce the perioperative period risks.

Abstract
Objective: To investigate the clinicopathological characteristics and prognostic factors of neuroendocrine carcinoma (NEC) of the cervix. Methods: Eight-two patients diagnosed as NEC of cervix from 2008 to 2016 at West China Second University Hospital were analyzed retrospectively including HE slide review, immunohistochemistry and HPV genotyping. Survival analysis was performed using Kaplan-Meier and Cox regression model. Results: The age of the patients ranged from 16 to 75 years with mean age of 43 years. According to International Federation of Gynecology and Obstetrics (FIGO) clinical stage, 52 cases were in stageⅠ, 10 cases in stageⅡ, 14 cases in stage Ⅲ and 6 cases in stage Ⅳ. The tumor size ranged from 0.5 to 6.5 cm, with an average of 3.6 cm. Upon histopathologic review, 74 tumors were classified as small cell carcinoma; 7 tumors as large cell NEC, and 1 as atypical carcinoid. Further evaluation showed 52 cases (63.4%) with deep stromal invasion, 73 cases (89.0%) with lymph-vascular invasion, and 28 cases (34.2%) with pelvic and (or) para-aortic lymph nodes involvement. Immunohistochemical staining showed neuroendocrine markers Syn, CD56, NSE, S-100 protein and CgA were positive in 93.9%, 84.2%, 74.4%, 64.6% and 51.2% of cases, respectively. The results of HPV-DNA detection were positive in 72 cases, high-risk HPV types were 70 cases and 49 cases were HPV18 positive. The median follow-up time was 37 months (range, 6-101 months). Twenty-nine cases were found recurrence or metastasis, including 23 cases of death. The univariate analysis demonstrated that the tumor size, lymph node metastasis, infiltration depth, FIGO stage and whether the lesion confined to the uterus were significant prognostic factors(P<0.05). Cox multivariate analysis showed that lymph node metastasis and FIGO stage were independent prognostic factors of NEC(P<0.05). Conclusions: NEC of the cervix is a highly aggressive malignancy with poor prognosis. The tumor is associated with HPV infection, especially type 18. Small cell NEC is the most common type of cervical NEC. Diagnosis is based on histological and immunohistochemical examination. Lymph node metastasis and FIGO stage are the independent factors affecting prognosis.

Abstract
Lysophosphatidic acid (LPA), which is one of the intermediate products of membrane phospholipid metabolism, is a bioactive phospholipid that possesses diverse activities. In the present study, the effects of LPA on neointimal formation following vascular injury were investigated. A carotid artery balloon injury model was employed in the present study, and following vascular injury, rats received an intraperitoneal injection of 1 mg/kg LPA. Subsequently, histopathological alterations were assessed by hematoxylin and eosin staining, the expression levels of proliferating cell nuclear antigen (PCNA) were detected by immunohistochemistry, apoptosis was assessed via a terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay, and the expression levels of apoptosis-associated and autophagy-associated proteins were detected by western blotting. In addition, inflammatory and oxidative stress-associated factors were assessed by reverse transcription-quantitative polymerase chain reaction or corresponding kits. The results of the present study demonstrated that LPA enhanced vascular injury-induced neointimal hyperplasia. LPA further elevated the expression levels of PCNA in the injured carotid artery tissues. LPA exhibited no effect on apoptosis in carotid artery tissues, whereas it modulated autophagy in the injured carotid artery tissues. Furthermore, LPA enhanced vascular injury-induced inflammation and oxidative stress. The present study demonstrated that LPA may enhance neointimal hyperplasia following vascular injury by modulating proliferation, autophagy, inflammation and oxidative stress, but not apoptosis. Furthermore LPA may contribute to the pathology of atherosclerosis and may be considered a promising therapeutic target for the treatment of atherosclerosis.

Abstract
Streptococcus mutans and Candida albicans are frequently co-isolated from dental plaque of children with early childhood caries (ECC) and are only rarely found in children without ECC, suggesting that these species interact in a manner that contributes to the pathogenesis of ECC. Previous studies have demonstrated that glucans produced by S. mutans are crucial for promoting the formation of biofilm and cariogenicity with C. albicans; however, it is unclear how non-glucan S. mutans biofilm factors contribute to increased biofilm formation in the presence of C. albicans. In this study we examined the role of S. mutans antigen I/II in two-species biofilms with C. albicans, and determined that antigen I/II is important for the incorporation of C. albicans into the two-species biofilm and is also required for increased acid production. The interaction is independent of the proteins Als1 and Als3, which are known streptococcal receptors of C. albicans. Moreover, antigen I/II is required for the colonization of both S. mutans and C. albicans during co-infection of Drosophila melanogaster in vivo. Taken together, these results demonstrate that antigen I/II mediates the increase of C. albicans numbers and acid production in the two-species biofilm, representing new activities associated with this known S. mutans adhesin.
