Abstract
Efficient enrichment and transmembrane transport of cytotoxic reagents are considered to be effective strategies to increase the efficiency and selectivity of antitumor drugs targeting solid tumors. In the present study, a recombinant protein ABD‑LDP‑Ec consisting of the albumin‑binding domain (ABD), the apoprotein (LDP) of lidamycin (LDM) and an EGFR‑targeting oligopeptide (Ec) was prepared by DNA recombination and bacterial fermentation, and was integrated with the enediyne chromophore (AE) of lidamycin to generate its enediyne‑integrated analogue ABD‑LDP‑Ec‑AE. ABD‑LDP‑Ec exhibited high binding capacity to both albumin and EGFR‑positive pancreatic cancer cells, and was internalized into the cytoplasm through receptor‑mediated endocytosis and albumin‑driven macropinocytosis of K‑ras mutant cells. In animal experiments, ABD‑LDP‑Ec demonstrated notable selective distribution in pancreatic carcinoma xenografts by passive targeting of albumin captured in the blood and was retained in the tumor for 48 h. ABD‑LDP‑Ec and ABD‑LDP‑Ec‑AE exhibited inhibitory activity in cell proliferation and AsPC‑1 xenograft growth, and ABD‑LDP‑Ec‑AE increased the tumor growth inhibition rate by 20% compared with natural LDM. The results indicated that the introduction of ABD‑based multi‑functional drug delivery may be an effective approach to improve the efficacy of antitumor drugs, especially for K‑ras mutant cancers.

Abstract
The C-X-C Motif Chemokine Receptor 4/C-X-C Motif Chemokine Ligand 12 (CXCR4/CXCL12) axis has been implicated in the pathogenesis of pulmonary fibrosis. However, the mechanisms governing this remain to be determined. The current study demonstrated that human lung fibroblasts (HLFs) exhibit high CXCL12 expression and also exhibit high expression of its corresponding receptor CXCR4. Exogenous CXCL12 was revealed to significantly promote the migration and proliferation of HLFs, and potentiate CXCR4 expression. These effects were demonstrated to be inhibited by AMD3100, which is an antagonist of CXCR4. Lung and bronchoalveolar lavage fluid CXCR4 and CXCL12 expression was upregulated by in vivo bleomycin administration, which was partially inhibited by pre-treatment with AMD3100. AMD3100 also reduced lung collagen content in the bleomycin model. Inhibiting CXCR4 was indicated to ameliorate the lung compliance and resistance of pulmonary fibrosis. In conclusion, the results of the present study suggested that autocrine CXCR4/CXCL12 axis is an important mechanism underlying the pathogenesis of idiopathic pulmonary fibrosis, and may serve as a potential therapeutic target that can be used in the treatment of pulmonary disease.

Abstract
BACKGROUND Natural killer (NK) cells play important roles in immune responses and have been wildly used in immunotherapy. Nevertheless, some limitations remain. It is urgent to explore novel and safe strategies to enhance NK cell activity. PURPOSE The aim of this study was to investigate the immuno-stimulatory effects and to reveal the molecular mechanism of LJ101019C, a derivative of a natural small-molecule compounds cajanine, on NK cells. METHODS Cell proliferation was examined by CCK8 assay, then we used the cytotoxicity detection kit to detect the cytotoxicity of NK cells. The change of cell cycle, intracellular reactive oxygen species (ROS) level and mitochondrial mass were evaluated by FACS and Operetta high-content image analysis, respectively. Furthermore, the IFN-γ secretion of NK cells were measured by ELISA. The Kv1.3 protein expression and function were detected by western blot and patch-clamp technique, respectively. The role of Kv1.3 in AKT/mTOR pathway activation was determined by western blot. RESULTS The results showed that LJ101019C at relatively low concentrations (0.05-0.1 µM) significantly increased the proliferation of NK cells. And 1 µM LJ101019C could elevate the proportion of NK cells in the S-phase of the cell cycle (*p < 0.1). Furthermore, the cytotoxic effects of NK cells targeting MIA PaCa-2 cells were significantly enhanced by 0.1 and 1 µM LJ101019C, and were associated with the enhanced secretion of IFN-γ by NK cells (*p < 0.1; **p < 0.05). 0.1 and 1 µM LJ101019C increased intracellular levels of ROS (**p < 0.05), and 0.1 µM LJ101019C elevated mitochondrial mass (*p < 0.1). Electrophysiological recordings indicated that LJ101019C led to a remarkably increase the Kv1.3 current density. Moreover, western blot results indicated that LJ101019C elevated Kv1.3 protein expression and activated AKT/mTOR signaling via increasing the expression of Kv1.3 in NK cells. CONCLUSION LJ101019C increases the proliferation and the cytotoxicity of NK cells at relatively low concentrations. The mechanism is the activation of AKT/mTOR signaling pathway driven by up-regulation of Kv1.3 in NK cells. These suggest LJ101019C is a promising candidate for improving the efficacy of NK cell-based immunotherapies.

Abstract
Sodium lignosulfonate is a polymer with extensive sources and abundant functional groups. Therefore, it has potential value for research and wide utilization. In this study, the adsorption material was prepared by blending sodium lignosulfonate and chitosan, which could adsorb anionic and cationic dyes and metal ions. The composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermogravimetry (TG). The results showed that the composite was cross-linked mainly by the strong electrostatic interaction between the protonated amino group in chitosan and the sulfonate group in sodium lignosulfonate. Moreover, the effects of initial concentration, adsorption time, initial pH, and mass ratio of chitosan to sodium lignosulfonate on the adsorption performance of the composite were investigated. Meanwhile, the adsorption processes were agreed well with the pseudo-second-order kinetic model and Langmuir isotherm model. The adsorption mechanism was that the electrostatic interaction between the protonated amino and hydroxyl groups of the composite with anionic (SO3 -) and HCrO4 - groups of Congo red and Cr(VI), respectively. In addition, the electrostatic interaction between SO3 - of the composite and positively charged group of Rhodamine B played an important role in the adsorption of Rhodamine B.

Abstract
The present study was aimed to establish a novel TaqMan real-time PCR (RTm-PCR) for detecting and typing bovine viral diarrhea virus (BVDV), and also to develop a diagnostic protocol which simplifies sample collection and processing. Universal primers and TaqMan-MGB probes were designed from the known sequences of conserved 5' - and 3'-untranslated regions (5'UTR, 3'UTR) of the NADL strain of BVDV. Prior to optimizing the assay, cDNAs were transcribed in vitro to make standard curves. The sensitivity, specificity and stability (reproducibility) were evaluated. The RTm-PCR was tested on the 312 feces specimens collected from persistently infected (PI) calves. The results showed the optimum conditions for RTm-PCR were 17.0 μmol/L primer, 7.5 μmol/L probe and 51.4°C annealing temperature. The established TaqMan RTm-PCR assay could specially detect BVDV without detecting any other viruses. Its detection limit was 1.55×100 copies/μL for viral RNA. It was 10000-fold higher than conventional PCR with excellent specificity and reproducibility. 312 samples were tested using this method and universal PCR from six dairy farms, respectively. Positive detections were found in 49 and 44 feces samples, respectively. The occurrence rate was 89.80%. In conclusion, the established TaqMan RTm-PCR could rapidly detect BVDV and effectively identify PI cattle. The detection limit of RTm-PCR was 1.55 copies/μL. It will be beneficial for enhancing diagnosis and therapy efficacy and reduce losses in cattle farms.

Abstract
The quantitative study of urban-rural gradients for persistent organic pollutants (POPs) is extremely important to understand the behavior of POPs as well as for ecological risk assessment and management. In this study, a practical urban-rural gradient model (URGM) was developed using atmospheric point source diffusion combined with a fugacity approach to test potential mathematical relationships among urban and rural soils. The mean value of polycyclic aromatic hydrocarbons (PAHs) for urban soils (0-2-km sites) was 570.80 ng/g, and was approximately 3.5 times higher than rural soils (30-50 km sites). Significant linear correlations were found between the amounts of PAHs in the surface soil and the city population and between the soil concentration and artificial surface area. Urban-rural PAH concentrations were simulated by the URGM and calibrated by city population and land-cover data, with average relative errors of 12.84%. The results showed that the URGM was suitable for simulating urban-rural PAH concentrations at a regional scale. The combustion of fossil fuels, biomass, and coal was the main source of soil PAHs in the study area, and the characteristic ratios of PAHs indicated a transition trend from pyrogenic to petrogenic sources along the urban-rural transects. This study thus provides a combined method for quantifying urban-rural gradients of PAHs and can thereby promote quantitative research on coupling among land cover, socio-economic data, and POP concentrations.

Abstract
NEW FINDINGS • What is the central question of this study? The aim was to explore the effects and underlying mechanisms of H2 on bleomycin-induced pulmonary fibrosis. • What are the main findings and its importance? Our results indicate that, in bleomycin-induced pulmonary fibrosis, H2 inhalation attenuated oxidative stress and reversed the pulmonary epithelial-to-mesenchymal transition process by reducing reactive oxygen species production and inhibiting the expression of transforming growth factor-β1, α-smooth muscle actin and collagen I to improve fibrotic injury and exert anti-fibrogenic effects. Thus, H2 inhalation has promising therapeutic potential as a useful adjuvant treatment for patients with idiopathic pulmonary fibrosis, which deserves further study and evaluation. ABSTRACT Hydrogen (H2 ) can protect against tissue damage. The effect of H2 inhalation therapy on the pathogenesis of pulmonary fibrosis remains unknown. This study was designed to explore the effects and underlying mechanisms of H2 inhalation on bleomycin (BLM)-induced pulmonary fibrosis. A rat model of pulmonary fibrosis was established with BLM. Rats were randomly divided into control and H2 inhalation groups. Haematoxylin and Eosin staining and Mason's Trichrome staining were performed to evaluate pulmonary fibrosis injury, inflammatory cell infiltration, structural disorder and collagen deposition. qRT-PCR and western blot assays were used to determine the expression of TNF-α, TGF-β1, α-SMA, E-cadherin, N-cadherin, vimentin, VEGF and collagen type I at both mRNA and protein levels. The contents of reactive oxygen species, TGF-β1, TNF-α, malondialdehyde and hydroxyproline were determined with biochemical test kits or ELISA kits. Bleomycin-stimulated rats exhibited typical symptoms of pulmonary fibrosis, which featured an increase in collagen deposition, alveolitis, fibrosis and parenchymal structural disorder in the lung. However, BLM-induced oxidative stress was attenuated by H2 inhalation therapy, which reduced the contents of reactive oxygen species, malondialdehyde and hydroxyproline, enhanced the activity of glutathione peroxidase and decreased the expression of TGF-β1 and TNF-α. In addition, H2 inhalation also inhibited BLM-induced epithelial-to-mesenchymal transition by inhibiting TGF-β1, increasing the expression level of the epithelial cell marker E-cadherin, and decreasing the expression level of the mesenchymal cell marker vimentin in a time-dependent manner. In addition, H2 inhalation downregulated α-SMA expression and suppressed collagen I generation, exerting anti-fibrogenic effects. Hydrogen inhalation therapy attenuates BLM-induced pulmonary fibrosis by inhibiting TGF-β1, relevant oxidative stress and epithelial-to-mesenchymal transition.

Abstract
BACKGROUND Mindfulness-based interventions may offer a promising approach for promoting psychological and physical health and wellbeing for patients with heart failure. However, the effects of mindfulness-based interventions for this population have not been systematically reviewed. AIMS This review aimed to synthesise available evidence to assess the effects of mindfulness-based interventions on psychological and physical outcomes and health-related quality of life in patients with heart failure. METHODS Seven English and two Chinese electronic databases were searched with keywords from inception to May 2019. Experimental studies that examined mindfulness-based interventions in adults with heart failure were eligible for inclusion. Two reviewers independently performed study selection, data extraction and study quality assessment. The results were then narratively synthesised. RESULTS This review identified five studies involving 467 patients with heart failure. The reviewed studies had weak to moderate quality. There were consistent findings that mindfulness-based interventions could significantly reduce depression (three studies) and anxiety (two studies) and improve health-related quality of life (two studies) after intervention. However, the effects on physical symptoms were inconsistent in three studies. The effects on physical function were only measured in one study, with non-significant changes being reported. CONCLUSIONS This review provides preliminary evidence that mindfulness-based interventions are beneficial for patients with heart failure in reducing depression and anxiety and enhancing health-related quality of life in the short term. These findings should be carefully generalised considering the methodological limitations across studies. More rigorous studies are required to examine further the effects of mindfulness-based interventions in patients with heart failure.

Abstract
Abstract
Introduction
Use of contrast media is necessary for diagnostic imaging and PCI. However, contrast-induced kidney injury has been identified as the most frequent cause of hospital-acquired acute kidney injury and is associated with poor prognosis. Currently, contrast-induced kidney injury cannot be diagnosed on the day of cardiac catheterization or on the following day, when the majority of patients who undergo elective cardiac catheterization are discharged from the hospital in the real-world setting. Recently, proenkephalin (penKid) was introduced as a new glomerular filtration marker, which is capable of identifying normal subjects at high risk of future decline in renal function. The aim of this study was to investigate whether the change in penKid level on the day following cardiac catheterization can predict kidney injury before hospital discharge and thus allows for early detection of affected patients.
Methods
A total of 214 consecutive patients who underwent routine cardiac catherization were recruited, and blood was drawn at three time-points: immediately before catherization, 12–24 hours after catheterization and 4–8 weeks after discharge. Creatinine was measured for endpoint definition, while the markers urea, CRP (C-reactive protein), NGAL (neutrophil gelatinase-associated lipocalin), KIM-1 (kidney injury marker-1), cystatin C, suPAR (soluble urokinase-type plasminogen activator receptor), and penKid were measured as biomarkers of interest. The main outcome measure was sustained kidney injury (SKI), which was defined as an increase above 20% in serum creatinine between time-points 1 and 3. The main test was whether the change in biomarkers between baseline and immediately before discharge (time-points 1 and 2) can predict the development of sustained kidney injury.
Results
While only 5.6% of subjects developed acute kidney injury as defined according to KDIGO guidelines (delta serum creatinine between time-points 1 and 2), sustained kidney injury at mid-term follow-up (4–8 weeks) was found in 28.7% of the subjects. None of the baseline biomarkers, including creatinine, reliably predicted SKI (AUC in ROC analyses between 0.50 and 0.60). In rule-out analyses, stable values of penKid (not increasing from before catherization to discharge next day) reliably ruled out SKI at a specificity of 96.0% (90.1–98.9), while specificity was lower for the other candidate biomarkers [CRP: 63.4% (53.2–72.7); NGAL: 55.3% (44.1–66.1); KIM-1: 63.9% (53.5–73.4); cystatin C: 93.0% (86.1–97.1); suPAR: 52.0% (41.8–62.1)]. Using penKid, only 7 patients were categorized as false-positive, while all other patients would have been discharged safely.
Study Flow PANCAKE-Study
Conclusion
Change in penKid levels between cardiac catheterization and discharge reliably rules out sustained kidney injury after contrast administration. PenKid thereby holds promise as an early biomarker for contrast-induced kidney injury and should be evaluated in pilot interventional trials.

Abstract
Andrias davidianus is widely recognized in traditional medicine as a cure-all to treat a plethora of ailments. In a previous study, a novel antibacterial peptide named andricin B was isolated from A. davidianus blood. In this study, we investigated andricin B structure and its mode of action. Circular dichroism spectra suggested that andricin B adopts a random coil state in aqueous solution and a more rigid conformation in the presence of bacteria. Moreover propidium iodide/fluorescein diacetate double staining indicated that bacteria treated with andricin B were not immediately eliminated. Rather, there is a gradual bacterial death, followed by a sublethal stage. Scanning electronic microscope imaging indicates that andricin B might form pores on cell membranes, leading to the release of cytoplasmic contents. These results were consistent with flow cytometry analysis. Furthermore, Fourier transform infrared spectroscopy suggests that andricin B induces changes in the chemical properties in the areas surrounding these "pores" on the cell membranes. SIGNIFICANCE AND IMPACT OF THE STUDY: The results of this study suggested the new perspectives about the mode of action of antimicrobial peptide (AMP) active against sensitive bacteria. The AMP was able to be in a random coiled state in aqueous solution but to change to a more rigid one in the presence of sensitive bacteria. Exposure to AMP might not lead to immediate death of treated bacteria, rather bacteria concentration decreased gradually flattening at a sublethal stage. These findings will help people to understand better how the AMPs activate against sensitive bacteria.

Abstract
Innovations in nanofabrication have expedited advances in hollow-structured nanomaterials with increasing complexity, which, at the same time, set challenges for the precise determination of their intriguing and complicated 3D configurations. Conventional transmission electron microscopy (TEM) analysis typically yields 2D projections of 3D objects, which in some cases is insufficient to reflect the genuine architectures of these 3D nano-objects, providing misleading information. Advanced analytical approaches such as focused ion beam (FIB) and ultramicrotomy enable the real slicing of nanomaterials, realizing the direct observation of inner structures but with limited spatial discrimination. Electron tomography (ET) is a technique that retrieves spatial information from a series of 2D electron projections at different tilt angles. As a unique and powerful tool kit, this technique has experienced great advances in its application in materials science, resolving the intricate 3D nanostructures. Here, the exceptional capability of the ET technique in the structural, chemical, and quantitative analysis of hollow-structured nanomaterials is discussed in detail. The distinct information derived from ET analysis is highlighted and compared with conventional analysis methods. Along with the advances in microscopy technologies, the state-of-the-art ET technique offers great opportunities and promise in the development of hollow nanomaterials.

Abstract
A novel and eco-friendly one-step approach has been developed to fabricate magnetic lignosulfonate (MLS) with high performance in wastewater treatment. The obtained MLS was characterized by FTIR, XRD, SEM, TEM, VSM. The results showed that MLS had a good magnetic behavior in an applied magnetic field and its saturation magnetization intensity was up to 43.98 emu/g. Moreover, MLS exhibited excellent adsorption properties for Cr(Ⅵ) (57.14 mg/g) and Rhodamine B (22.47 mg/g). Simultaneously, the adsorption kinetics and adsorption isotherm experiments indicated that the data was agreed well with the pseudo-second-order and Langmuir model, respectively. After five regeneration cycles, the desorption efficiencies of Cr(Ⅵ) and Rhodamine B could reach more than 70% and 85%, respectively. Hence, the magnetic lignosulfonate is a promising material as a highly adsorptive and recyclable adsorbent for removing metal ions and cationic pollutants in wastewater.

Abstract
Background Pancreatic cancer stem cells (CSCs), a special population of cells, renew themselves infinitely and resist to various treatment. Gramicidin A (GrA), an ionophore antibiotic derived from microorganism, can form channels across the cell membrane and disrupt cellular ionic homeostasis, leading to cell dysfunction and death. As reported, the ionophore antibiotic salinomycin (Sal) has been proved to kill CSCs effectively. Whether GrA owns the potential as a therapeutic drug for CSCs still remains unknown. This study investigated the effect of GrA on pancreatic CSCs and the mechanism. Methods Tumorsphere formation assay was performed to assess pancreatic CSCs self-renewal potential. In vitro hemolysis assay was determined to test the borderline concentration of GrA. CCK-8 assay was used to detect pancreatic cancer cell proliferation capability. Flow cytometry was performed to detect cell apoptosis and mitochondrial membrane potential. Scanning and transmission electron microscopy was used to observe ultrastructural morphological changes on cell membrane surface and mitochondria, respectively. Western blot analysis was used to determine relative protein expression levels. Immunofluorescence staining was performed to observe CD47 re-distribution. Results GrA at 0.05 μM caused tumorspheres disintegration and decrease in number of pancreatic cancer BxPC-3 and MIA PaCa-2 cells. GrA and Sal both inhibited cancer cell proliferation. The IC50 values of GrA and Sal for BxPC-3 cells were 0.025 μM and 0.363 μM; while for MIA PaCa-2 cells were 0.032 μM and 0.163 μM, respectively. Compared on equal concentrations, the efficacy of GrA was stronger than that of Sal. GrA at 0.1 μM or lower did not cause hemolysis. GrA induced ultrastructural changes, such as the decrease of microvilli-like protrusions on cell surface membrane and the swelling of mitochondria. GrA down-regulated the expression levels of CD133, CD44, and CD47; in addition, CD47 re-distribution was observed on cell surface. Moreover, GrA showed synergism with gemcitabine in suppressing cancer cell proliferation. Conclusions The study found that GrA was highly active against pancreatic CSCs. It indicates that GrA exerts inhibitory effects against pancreatic CSCs associated with CD47 down-regulation, implying that GrA might play a positive role in modulating the interaction between macrophages and tumor cells.

Abstract
Objective:To investigate CPC-nanoparticles of low concentrations in treatment of staphylococcus aureus and pseudomonas aeruginosa biofilms in vitro. Method: We established specific biofilms of staphylococcus aureus ATCC 25923 and pseudomonas aeruginosa ATCC 15692, and prepared CPC-nanoparticles and CPC micelle solutions of low concentrations(0.010%, 0.025% and 0.050%). AlamarBlue was used to test the viability of both planktonic staphylococcus aureus and pseudomonas aeruginosa and their biofilms after treatment for 5 minutes and 2 hours respectively in the bactericidal efficacy study.The interaction between CPC-nanoparticles and staphylococcus aureus and pseudomonas aeruginosa biofilms was observed by confocal laser scanning microscope(CLSM). Result: 0.010%, 0.025% and 0.050% CPC-nanoparticles and CPC-micelle solutions had significant bactericidal effect on planktonic staphylococcus aureus and pseudomonas aeruginosa after fiveminute exposure(P<0.05), and staphylococcus aureus and pseudomonas aeruginosa biofilms after both five-minute and two-hour treatments(P<0.05). In CLSM study, the size of staphylococcus aureus biofilms decreased, while dead bacteria of pseudomonas aeruginosa biofilms increased after two-hour treatment. Conclusion: CPC-nanoparticles had significant bactericidal effects on staphylococcus aureus and pseudomonas aeruginosa biofilms, which could be used in treatment of CRS.

Abstract
Multi-turn response selection is essential to retrieval-based chatbots. The task requires multi-turn response selection model to match a response candidate with a conversation context. Existing methods may lose relationship features in the context. In this article, we propose an improved method that extends the learning granularity of the multi-turn response selection model to enhance the model’s ability to learn relationship features of utterances in the context, which is a key to understand a conversation context for multi-turn response selection in retrieval-based chatbots. The experimental results show that our proposed method significantly improves sequential matching network for multi-turn response selection in retrieval-based chatbots.

Abstract
The external factors that modulate Hippo signaling remain elusive. Here, we report that FGF15 activates Hippo signaling to suppress bile acid metabolism, liver overgrowth, and tumorigenesis. FGF15 is induced by FXR in ileal enterocytes in response to increased amounts of intestinal bile. We found that circulating enterohepatic FGF15 stimulates hepatic receptor FGFR4 to recruit and phosphorylate NF2, which relieves the inhibitory effect of Raf on the Hippo kinases Mst1/2, thereby switching FGFR4's role from pro-oncogenic to anti-tumor signaling. The activated Mst1/2 subsequently phosphorylates and stabilizes SHP to downregulate the key bile acid-synthesis enzyme Cyp7a1 expression, thereby limiting bile acid synthesis. In contrast, Mst1/2 deficiency impairs bile acid metabolism and remarkably increases Cyp7a1 expression and bile acid production. Importantly, pharmacological depletion of intestinal bile abrogates Mst1/2-mutant-driven liver overgrowth and oncogenesis. Therefore, FGF15-Hippo signaling along the gut-liver axis acts as a sensor of bile acid availability to restrain liver size and tumorigenesis.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy with high mortality. Lack of effective treatment makes novel therapeutic discovery an urgent demand in PDAC research. By screening an epigenetic-related compound library, we identified THZ1, a covalent inhibitor of CDK7, as a promising candidate. Multiple long-established and patient-derived PDAC cell lines (PDC) were used to validate the efficacy of THZ1 in vitro. In addition, patient-derived xenograft (PDX) models and animal models of PDAC were utilized for examining THZ1 efficacy in vivo. Furthermore, RNA-Seq analyse was performed to reveal the molecular mechanism of THZ1 treatment. Finally, PDAC cell lines with primary or acquired resistance to THZ1 were investigated to explore the potential mechanism of THZ1 susceptibility. CDK7 inhibition was identified as a selective and potent therapeutic strategy for PDAC progression in multiple preclinical models. Mechanistic analyses revealed that CDK7 inhibition led to a pronounced downregulation of gene transcription, with a preferential repression of mitotic cell cycle and NF-κB signaling-related transcripts. MYC transcriptional was found to be involved in susceptibility of PDAC cells to CDK7 inhibition. In conclusion, Identification of CDK7-dependent transcriptional addiction in PDACs provides a potent therapeutic strategy that targets highly aggressive pancreatic cancer.

Abstract
The aim of this study was to investigate the role of lncRNA NEAT1 (nuclear enriched abundant transcript 1) in regulating Th2 cell differentiation. The overexpression vectors of NEAT1 and ITCH, and siRNA targeting NEAT1, EZH2 (enhancer of zeste homolog 2) and STAT6 (signal transducer and activator of transcription 6) were transfected into CD4+T cells. The mRNA expressions of ITCH and STAT6 were analyzed by qRT-PCR and western blotting. The levels of Th2 cytokines were detected by ELISA assay. RIP and ChIP assays were performed to analyze the association between NEAT1 and EZH2 as well as EZH2 and STAT6, respectively. Results showed that NEAT1 significantly repressed ITCH expression and increased STAT6 expression as well as the levels of IL-4, IL-5 and IL-13 in CD4+T cells. RIP and ChIP assays revealed that NEAT1 bound to EZH2 and EZH2 was recruited to the promoter region of ITCH in CD4+T cells. Silencing EZH2 significantly promoted STAT6 for ubiquitination. Furthermore, NEAT targeted STAT6 for ubiquitination and elevated levels of Th2 cytokines by regulating EZH2/ITCH axis. In conclusion, our data indicated that NEAT1 promotes Th2 cell differentiation through the EZH2/ITCH/STAT6 axis.

Abstract
The search for an economical electrocatalyst for oxygen reduction reaction (ORR) is a worldwide issue for fuel cells and metal–air batteries. Herein, we used cheap and available high-sulfur inferior coal as the single precursor to synthesize an N, S dual-doped carbon (NSC) metal-free electrocatalyst for the ORR. The N, S dual-doped carbon (NSC), prepared at 800 °C (NSC800), possessed a large specific surface area of 942 m2 g−1, with an amorphous carbon structure and more defects than the others. Furthermore, it contains 1.06 at% N and 2.24 at% S, where N is resolved into pyridinic-N, pyrrolic-N, and graphitic-N. For the electrochemical behavior, NSC800 displayed a good ORR electrocatalytic activity, with the ORR peak potential at −0.245 V (vs. SCE) and half-wave potential (E1/2) at −0.28 V (vs. SCE) in an alkaline solution. This study not only gives an original and facile method to prepare an economical ORR electrocatalyst but also provides a novel clean-use of high-sulfur inferior coal. The search for an economical electrocatalyst for oxygen reduction reaction (ORR) is a worldwide issue for fuel cells and metal–air batteries.![]()

Abstract
BACKGROUND Previous studies suggest that dexmedetomidine has a protective effect against local anaesthetic-induced nerve injury in regional nerve blocks. Whether this potentially protective effect exists in the context of diabetes mellitus is unknown. METHODS A diabetic state was established in adult male Sprague-Dawley rats with intraperitoneal injection of streptozotocin. Injections of ropivacaine 0.5%, dexmedetomidine 20 μg kg-1 (alone and in combination), or normal saline (all in 0.2 ml) were made around the sciatic nerve in control and diabetic rats (n=8 per group). The duration of sensory and motor nerve block and the motor nerve conduction velocity (MNCV) were determined. Sciatic nerves were harvested at post-injection day 7 and assessed with light and electron microscopy or used for pro-inflammatory cytokine measurements. RESULTS Ropivacaine and dexmedetomidine alone or in combination did not produce nerve fibre damage in control non-diabetic rats. In diabetic rats, ropivacaine induced significant nerve fibre damage, which was enhanced by dexmedetomidine. This manifested with slowed MNCV, decreased axon density, and decreased ratio of inner to outer diameter of the myelin sheath (G ratio). Demyelination, axon disappearance, and empty vacuoles were also found using electron microscopy. An associated increase in nerve interleukin-1β and tumour necrosis factor-α was also seen. CONCLUSIONS Ropivacaine 0.5% causes significant sciatic nerve injury in diabetic rats that is greatly potentiated by high-dose dexmedetomidine. Although the dose of dexmedetomidine used in this study is considerably higher than that used in clinical practice, our data suggest that further studies to assess ropivacaine (alone and in combination with dexmedetomidine) use for peripheral nerve blockade in diabetic patients are warranted.

Abstract
The present study evaluated the diagnostic value of contrast-enhanced ultrasound (CEUS) in endometrial carcinoma (EC). Articles published until 31 January 2017 were retrieved from PubMed, EMBASE, Elsevier, Springer and Google scholar, with the following inclusion criteria: i) The accuracy (sensitivity and specificity) of CEUS in the diagnosis of EC was evaluated; ii) a gold standard was adopted to treat and confirm EC, including surgery, histopathology and appropriate follow-up (as included in the meta-analysis); iii) the data allowed for construction of a 2×2 table of positives, false-positives, negatives and false-negatives. Pooled estimates of sensitivity, specificity, risk ratios and diagnostic odds ratios (DOR) were calculated in the present meta-analysis of the accuracy of CEUS in diagnosing EC. The summary receiver-operating characteristics (sROC) curve was also constructed. Among the 93 relevant articles, 7 studies were finally selected according to the inclusion criteria with a sample size of n=275. The pooled sensitivity of CEUS in the diagnosis of EC was 84% [95% confidence interval (CI), 0.78-0.88], while the pooled specificity was 90% (95% CI, 0.86-0.92). The positive likelihood ratio (+LR) of CEUS was 8.0 (95% CI, 5.9-10.8) and the negative likelihood ratio (-LR) was 0.18 (95% CI, 0.13-0.25). The DOR was 44 (95% CI, 26-77). The area under the sROC curve was 0.93 with specificity of 0.90 (0.86-0.92) and sensitivity of 0.84 (0.78-0.88) for the summary operating point. Moderate heterogeneity was observed for sensitivity, specificity and DOR with I2 values of 32.56, 34.68 and 41.2%, respectively. No significant publication bias was observed for the DOR of CEUS. In conclusion, the present meta-analysis indicates that CEUS is valuable in the diagnosis of EC. Additional clinical data and studies are still required to confirm these results and to further develop the diagnostic application of CEUS in EC.

Abstract
BACKGROUND Higenamine (HG) is an active compound derived from Aconiti root with a cardiotonic effect. It has been approved by the Chinese SFDA for clinical trials due to its effect as a potent inotropic and chronotropic agent in the heart. However, the direct mode of action of HG on cardiac electrophysiology is unclear. METHODS The experiments were performed at both cell levels and the isolated organ. The major cardiac ion currents and the action potential duration (APD) were measured using patch-clamps in single guinea-pig left ventricular myocytes. ECG was recorded in isolated guinea pig hearts. RESULTS In the left ventricular myocytes, HG increased ICa-L and IKs in concentration- and voltage-dependent manners in the left ventricular myocytes. It potentiated the ICa-L and IKs simultaneously for synchronization. The EC50 values were 0.27 μM and 0.64 μM for the ICa-L and IKs, respectively. HG (0.1 μM, 0.5 μM and 1 μM) had no effect on the IKr and INa. HG slightly prolonged APD at lower concentrations, and shortened the APD at higher concentrations. HG can induce the delayed after depolarization (DAD), which showed some pro-arrhythmic effect. In the isolated perfused heart, HG increased the heart rate via an action on the sinoatrial node cells, but did not induce cardiac arrhythmias, even at high concentrations. The EC50 value for the sinoatrial node that controls the heart rate was 0.13 μM. The sinoatrial node cells appeared to be more sensitive than ventricular myocytes to HG. The effects of HG on ventricular cells and sinoatrial node cells were both mediated through stimulation of β1-AR. CONCLUSION We show for the first time that HG produced a predominant action on the sinoatrial node. HG appears to control the cardiac electrophysiology through its predominant effect on the sinoarial node cells, without induction of the ectopic activity that causes cardiac arrhythmias. Thus, HG might be useful for the treatment of bradycardia.

Abstract
Objective: To investigate the risk factors of ventricular arrhythmias in patients with Brugada syndrome. Methods: Clinical data of 60 Brugada syndrome patients admitted in the department of cardiology of the First Affiliated Hospital of Nanjing Medical University from March 2003 to December 2016 were collected and retrospectively analyzed. The age at diagnosis was (43.2±13.1) years (0.6-83.0 years), 98.3% were males (n=59), and the patients were followed up to (92±41) months (12-169 months). The 12-lead surface electrocardiogram (ECG) recorded at the time of diagnosis and showing the highest type 1 ST elevation, either spontaneously or after provocative drug test, was used for the analysis. Patients were divided into ventricular arrhythmia (VA, n=12) group and non-ventricular arrhythmia (non-VA, n=48) group depending on the presence or absence of clinical VA event. The demographic data and ECG data of the 2 groups were compared, and the independent risk factors of VA events were analyzed by stepwise logistic regression. Results: Incidence of family history of sudden death (7/12 vs. 22.9% (11/48)) and percentage of type 1 ST elevation in the peripheral ECG leads (6/12 vs. 16.67% (8/48)) were significantly higher in VA group than in non-VA group (both P<0.05). Max Tpeak-Tend (Max-Tpe) interval ((144±53)ms vs. (110±16)ms) and dispersion of Tpe ((74±50)ms vs. (43±17)ms) were significantly higher in VA group than in non-VA group (both P<0.05). The area under receiver operating characteristic (ROC) curves for the Max-Tpe interval was 0.693 and Max-Tpe interval ≥140 ms was determined as an optimized cutoff point with increased risk of VA event, which had a sensitivity of 50.0%, a specificity of 98.0%, a positive predictive value of 85.7%, and a negative predictive value of 88.7% for predicting VA event. The ROC curves for the dispersion of Tpe was 0.775 and dispersion of Tpe ≥45 ms was determined as an optimized cutoff point for predicting VA event, which had a sensitivity of 91.7%, a specificity of 64.6%, a positive predictive value of 39.3%, and a negative predictive value of 96.9% for predicting VA event. In multivariate analysis, Max-Tpe interval ≥140 ms (OR=27.53, 95%CI 1.07-706.77, P=0.045) and family history of sudden death (OR=24.63, 95%CI 2.05-295.38, P=0.011) were found to be the independent risk factors of arrhythmic events. Conclusions: Max-Tpe interval ≥140 ms and family history of sudden death are risk factors of VA event in included patients with Brugada syndrome.

Abstract
This study analysed spatial-temporal dynamics of carbon emissions and carbon sinks in Guangdong Province, South China. The methodology was based on land use/land cover data interpreted from continuous high-resolution satellite images and energy consumption statistics, using carbon emission/sink factor method. The results indicated that: (1) From 2005 to 2013, different land use/land cover types in Guangdong experienced varying degrees of change in area, primarily the expansion of built-up land and shrinkage of forest land and grassland; (2) Total carbon emissions increased sharply, from 76.11 to 140.19 TgC yr−1 at the provincial level, with an average annual growth rate of 10.52%, while vegetation carbon sinks declined slightly, from 54.52 to 53.20 TgC yr−1. Both factors showed significant regional differences, with Pearl River Delta and North Guangdong contributing over 50% to provincial carbon emissions and carbon sinks, respectively; (3) Correlation analysis showed social-economic factors (GDP per capita and permanent resident population) have significant positive impacts on carbon emissions at the provincial and city levels; (4) The relationship between economic growth and carbon emission intensity suggests that carbon emission efficiency in Guangdong improves with economic growth. This study provides new insight for Guangdong to achieve carbon reduction goals and realize low-carbon development.

Abstract
OBJECTIVES It is necessary to assess disease-related knowledge in patients with coronary artery disease (CAD) for tailored patient education; however there is a lack of a well-validated measurement in China. The objective of this study was to translate and validate a Chinese version of the Coronary Artery Disease Education Questionnaire-II (CADEQ-II). METHODS The Chinese version of CADEQ-II was translated and culturally adapted. Then, it was tested for psychometric properties through a convenient sampling. Content validity was examined based on a panel of five experts. The item difficulty index and item discrimination index were calculated to assess the item difficulty and item discrimination. Internal consistency reliability was measured with the Cronbach's alpha coefficient. Criterion-related validity was established through comparing scores in patients with different education levels. Construct validity was assessed through confirmatory factor analysis (CFA). RESULTS The Chinese version of the CADEQ-II was finalized after deleting three items and modifying two items from the original version. Three hundred and sixteen participants completed the whole questionnaire. Content validity index of the whole questionnaire was 0.87. The Cronbach's alpha coefficient of the overall questionnaire was 0.907. The significant difference of the knowledge scores among patients with different education levels supported criterion-related validity. CFA confirmed the proposed four-factorial structure of the questionnaire. CONCLUSION The Chinese version of CADEQ-II had an acceptable reliability and validity among Chinese patients with CAD. It could be used to develop individualized health education for Chinese patients with CAD. Also, it could serve as a suitable outcome measurement to evaluate the effectiveness of education interventions related to CAD.

Abstract
OBJECTIVE This study was designed to evaluate the significance of transperineal two-dimensional ultrasound in the diagnosis and classification of female stress urinary incontinence (SUI). METHODS A total of 87 preoperative SUI patients (group A) from the Department of Gynecology of Peking University People's Hospital were included into this study. These patients were further divided into two groups (groups A1 and A2) according to the severity of their disease. In addition, during the same period, 72 age-matched women without SUI were enrolled into this study and assigned as the control group (group B). Through transperineal two-dimensional ultrasound technique, detrusor wall thickness (DWT) was measured in the resting state, the bladder neck descent (BND) was measured under the maximal valsalva maneuver, the proximal urethral rotation angle (α angle) and posterior vesicourethral angle (β angle) were measured, and the formation of the funnel-shaped urethra was observed. RESULTS Under the resting state, differences in DWT between groups A and B, as well as between groups A1 and A2, were not statistically significant (P> 0.05). The BND, α and β angles were significantly larger in group A than in group B under the maximal Valsalva maneuver; and the differences were statistically significant (P< 0.05). The formation rate of the funnel-shaped urethra was significantly higher in group A (94%) than in group B (3%), and the difference was statistically significant; while the difference between groups A1 and A2 was not statistically significant (P> 0.05). CONCLUSION Transperineal two-dimensional ultrasound can play an assistant role in the diagnosis of female SUI. However, its role in the assessment of the severity of SUI remains to be studied.

Abstract
Chronic inflammation is a feature of pancreatic cancer, but little is known about how immune cells or immune cell-related signals affect pancreatic cancer stemness and development. Our previous work showed that IL22/IL22RA1 plays a vital role in acute and chronic pancreatitis progression by mediating cross-talk between immune cells and acinar cells or stellate cells, respectively. Here, we find IL22RA1 is highly but heterogeneously expressed in pancreatic cancer cells, with high expression associated with poor prognosis of patients with pancreatic cancer. The IL22RA1hi population from pancreatic cancer harbored higher stemness potential and tumorigenicity. Notably, IL22 promoted pancreatic cancer stemness via IL22RA1/STAT3 signaling, establishing the mechanism of regulation of cancer stemness by microenvironmental factors. Moreover, STAT3 was indispensable for the maintenance of IL22RA1hi cells. Overall, these findings provide a therapeutic strategy for patients with PDAC with high expression of IL22RA1.Significance: IL22RA1/STAT3 signaling enhances stemness and tumorigenicity in pancreatic cancer.

Abstract
The present study was designed to determine the role of PKD in vascular remodeling (VR) in Spontaneously hypertensive rats (SHRs). Increased SBP, VR and PKD activation were prominent in SHRs. The SBP has a positive correlation with the activation of PKD in SHRs. The ratio of media to lumen (MT/LD), volume fraction of collagen (VFC), hydroxyproline, IL-6, TNF-α and nitrotyrosine content were significantly related to the activated PKD. It may be concluded that PKD plays a central role in VR, and the mechanism may be related to its regulation of hypertrophy, fibrosis, inflammation and oxidative stress.

Abstract
Congenital scoliosis, a commonly seen disease occurring in children, can not only affect the growth, but also can uglify the individual which can severely affect the health and quality of life of children. To investigate the efficacy of posterior hemivertebra resection in combination with screw rod internal fixation in the treatment of congenital hemivertebra scoliosis, 115 patients were randomly divided into an observation group and a control group. Patients in the observation group were treated by posterior hemivertebra resection in combination with screw rod internal fixation, while patients in the control group were treated by posterior hemivertebra resection only. The surgical evaluation indicators, postoperative improvement of scoliosis and incidence of complications were recorded. The results demonstrated that the observation group had longer average operation time and less average blood loss compared to the control group, and the differences had statistical significance (P less than0.05); the correction efficacy of the observation group was superior to that of the control group (P less than 0.05); the incidence of postoperative complications in the two groups had no significant difference, but the incidence of correction loss of the observation group was much lower than that of the control group (P less than 0.05). In conclusion, posterior hemivertebra resection in combination with screw rod internal fixation is a highly efficient and safe treatment which can significantly relieve the clinical symptoms and cause few complications.

Abstract
Pulmonary fibrosis (PF) associated with chronic sarcoidosis remains poorly understood, and no experimental model is currently available for this condition. Previous studies have shown that Propionibacterium acnes (PA) was associated with sarcoidosis and induced granuloma formation in mice. Here, we investigated whether repeated challenge with PA induces persistent inflammation leading to sarcoidosis followed by PF in mice. Specifically, C57BL/6 mice were inoculated intraperitoneally and subjected to intratracheal challenge with PA, and then were booster-challenged with either PA or phosphate-buffered saline on day 28. Inflammation, granulomata, and features of fibrosis were evaluated every 7 days until day 70. Complete remission of lung granulomata was apparent on day 42 in the sarcoid-remission group. However, granulomata was present from days 21 to 70 in mice that received PA boosting. Inflammatory cell counts and Th1 cytokine levels in lung lavage fluids were elevated up to day 70. Furthermore, fibrotic changes in the lungs were observed around granulomatous and peribronchovascular regions after PA boosting. Taken together, these findings suggest that development of PF following sarcoidosis may result from continuous PA infection and inflammation. Repeated boosting with PA to induce PF might be a useful model for future studies of sarcoidosis-associated PF.

Abstract
Background: We investigated the association between serum levels of glial fibrillary acidic protein (GFAP) and stroke functional outcomes in a cohort of 286 patients with acute ischemic stroke (AIS). Methods: We prospectively studied 286 patients with AIS who were admitted within 24 h after the onset of symptoms. Serum levels of GFAP and National Institutes of Health Stroke Scale (NIHSS) were measured at admission. The primary end point was stroke functional outcome among 1-year after stroke onset. We used logistic regression models to assess the relationship between GFAP levels and stroke outcomes. Results: The GFAP level was obtained with a median value of 0.18 (interquartile ranges (IQRs): 0.09–0.28) ng/ml. In multivariable models adjusted for age, gender, and other risk factors, GFAP levels were associated with an increased risk of a NIHSS>6 (odds ratio (OR) = 1.55; 95% confidence interval (CI): 1.16–1.89; p = 0.012). The poor outcome distribution across the GFAP quartiles ranged between 12.7% (first quartile) and 70.4% (fourth quartile). After adjusting for other established risk factors, in multivariate models comparing the Q3 and Q 4 quartiles against the Q1 of the GFAP, the levels of GFAP were associated with poor outcome, and the adjusted risk of poor outcome increased by 211% (3.11[1.80–5.05], p < 0.001) and 522% (6.22[2.98–11.83], p < 0.001), respectively. Interestingly, GFAP improved the ability of NIHSS score to diagnose poor outcomes (area under the curve [AUC] of the combined model 0.82; 95% CI: 0.77–0.88; p = 0.02). Conclusion: GFAP levels are a novel and complementary biomarker to predict functional outcome 1 year after AIS

Abstract
In this study, hybrid BHJ – bulk heterojunction polymer solar cells were fabricated by incorporating CdS quantum dots (QDs) in a blend of P3HT (donor) and PCBM (acceptor) using dichlorobenzene and chlorobenzene as solvents. CdS QDs at various ratios were mixed in a fixed amount of the P3HT and PCBM blend. The prepared samples have been characterized by a variety of techniques such as I–V and EQE measurements, atomic force microscopy (AFM), scanning electron microscopy (SEM) and ultraviolet-visible (UV-vis) spectroscopy. The mixing of QDs in the polymer blends improved the PCE – power conversion efficiency of the solar cells under standard light conditions. The improved PCE from 2.95 to 4.41% is mostly due to the increase in the fill factor (FF) and short-circuit current (Jsc) of the devices with an optimum amount of CdS in the P3HT:PCBM blend. The increase in Jsc possibly originated from the formation of a percolation network of CdS. The conjugation of QDs has increased the absorption of the active layers in the visible region. These results well matched as reported, conjugation of CdS in the perovskite active layer increased the absorption and PCE of the devices relative to those of the perovskite films. This increment in parameters is attributed to the decrease in charge recombinations that improved the performance of the doped device. In this study, hybrid BHJ – bulk heterojunction polymer solar cells were fabricated by incorporating CdS quantum dots (QDs) in a blend of P3HT (donor) and PCBM (acceptor) using dichlorobenzene and chlorobenzene as solvents.![]()

Abstract
Tissue repair and regenerative medicine address the important medical needs to replace damaged tissue with functional tissue. Most regenerative medicine strategies have focused on delivering biomaterials and cells, yet there is the untapped potential for drug-induced regeneration with good specificity and safety profiles. The Hippo pathway is a key regulator of organ size and regeneration by inhibiting cell proliferation and promoting apoptosis. Kinases MST1 and MST2 (MST1/2), the mammalian Hippo orthologs, are central components of this pathway and are, therefore, strong target candidates for pharmacologically induced tissue regeneration. We report the discovery of a reversible and selective MST1/2 inhibitor, 4-((5,10-dimethyl-6-oxo-6,10-dihydro-5H-pyrimido[5,4-b]thieno[3,2-e][1,4]diazepin-2-yl)amino)benzenesulfonamide (XMU-MP-1), using an enzyme-linked immunosorbent assay-based high-throughput biochemical assay. The cocrystal structure and the structure-activity relationship confirmed that XMU-MP-1 is on-target to MST1/2. XMU-MP-1 blocked MST1/2 kinase activities, thereby activating the downstream effector Yes-associated protein and promoting cell growth. XMU-MP-1 displayed excellent in vivo pharmacokinetics and was able to augment mouse intestinal repair, as well as liver repair and regeneration, in both acute and chronic liver injury mouse models at a dose of 1 to 3 mg/kg via intraperitoneal injection. XMU-MP-1 treatment exhibited substantially greater repopulation rate of human hepatocytes in the Fah-deficient mouse model than in the vehicle-treated control, indicating that XMU-MP-1 treatment might facilitate human liver regeneration. Thus, the pharmacological modulation of MST1/2 kinase activities provides a novel approach to potentiate tissue repair and regeneration, with XMU-MP-1 as the first lead for the development of targeted regenerative therapeutics.

Abstract
OBJECTIVE To investigate the incidence and risk factors of lung cancer in patients with idiopathic pulmonary fibrosis (IPF), and to learn the clinical, imaging and pathological features and of lung cancer in IPF. METHODS The study population included consecutive 268 IPF patients. Of them, 46 patients had pathologically or cytologically proven lung cancer. The demographic, clinical, HRCT and pathological features in patients with IPF and lung cancer were analysed and compared with the patients with IPF alone. RESULTS Of 268 IPF patients, 46 patients were diagnosed as IPF with lung cancer, accounted for 17.16%. 45.65% were adenocarcinoma. Lung cancer located mostly in the peripheral area and lower lobes of lungs consistent with IPF affected area. Old age and heavy smoking were risk factors of lung cancer developing in IPF. Chest pain and haemoptysis were more frequent in IPF patients with lung cancer than without lung cancer (P = .000). Nodular or mass shadows were found only in IPF patients with lung cancer (P = .000). The levels of CEA and CA125 in IPF patients were much higher in IPF patients with lung cancer (P ≤ .001). The median survival time was 36.2 ± 22.7 months in IPF patients, longer than 6.9 ± 3.3 months in IPF patients with lung cancer (P < .001). CONCLUSIONS Lung cancer frequently develops in patients with IPF, which is mainly adenocarcinoma, located in IPF affected area. Chest pain and haemoptysis are potential indicative of lung cancer developing in patients with IPF as atypical nodes or masses located in the peripheral areas and lower lobes on chest HRCT.

Abstract
Human facial expressions are key ingredient to convert an individual's innate emotion in communication. However, the variation of facial expressions affects the reliable identification of human emotions. In this paper, we present a cloud model to extract facial features for representing human emotion. First, the uncertainties in facial expression are analyzed in the context of cloud model. The feature extraction and representation algorithm is established under cloud generators. With forward cloud generator, facial expression images can be re-generated as many as we like for visually representing the extracted three features, and each feature shows different roles. The effectiveness of the computing model is tested on Japanese Female Facial Expression database. Three common features are extracted from seven facial expression images. Finally, the paper is concluded and remarked.

Abstract
Ovarian cancer is one of the most common gynecologic cancers and the leading cause of mortality in women worldwide. HER2/neu is overexpressed in various types of cancers and is most commonly associated with decreased survival. Trastuzumab is a humanized anti-HER2 monoclonal antibody for the treatment of HER2-positive breast cancers. However, primary and/or acquired resistance occurs in up to 62% patients during the first year of treatment. Vascular endothelial growth factor (VEGF) is a well‑known angiogenesis factor involved in many physiological and pathological processes. Its significance has been implicated in promoting tumor growth and metastasis via angiogenesis. In the present study, we demonstrated that the upregulation of SP1 enhanced expression of VEGF promoting the angiogenesis and migration of trastuzumab-resistant ovarian cancer cell line SKOV3-T. Our in vitro and in vivo results both gave evidence that the SP1-VEGF axis was responsible for the enhanced malignancy, angiogenesis and migration in the acquired trastuzumab-resistant ovarian cancer cell model.

Abstract
The Hippo signaling pathway, first identified in Drosophila, has emerged as a critical regulator for controlling the size of organs. Activation of the Hippo signaling pathway negatively regulates the Yorkie ortholog YAP in multiple organs, important in the regulation of cell proliferation, differentiation, and apoptosis during development. The Serine/Threonine protein kinases MST1 and MST2, mammalian homologs of the Drosophila Hippo kinase, play central roles in the Hippo signaling pathway in mammals. Recent studies reveal that non-canonical Hippo signaling pathways are also involved in the regulation of various other biological processes, particularly the important roles of MST1 and MST2 kinases in immune cell activation, adhesion, migration, growth, and apoptosis. In this review, we summarize the recent advances in understanding the roles of MST1 and MST2 kinases in the regulation of the functions of T lymphocytes and innate immune cells.

Abstract
Objective: To verify whether preprocedural ultrasound of the lumbar spine could improve first-attempt success rate (defined as a successful neuraxial anesthesia with only one skin puncture) of neuraxial block in elderly patients. Methods: From septemble 2015 to February 2016, 200 elderly patients undergoing lower-limb surgery with neuraxial block at the Peking Universty Third Hospital were enrolled in this study.RandA 1.0 software was used to randomize patients into two groups: conventional surface landmark-guided group (group LM) and ultrasound-assisted group (group US). Ultrasound scanning of the lumbar spine was performed to determine the suitable insertion point of US group, using a low-frequency (2-5 MHz) curved-array probe in both paramedian sagittal oblique plane and transverse median plane.Spinal anesthesia was done via the paramedian approach.The primary outcome was the rate of successful access to subarchnoid space on the first needle insertion attempt.Secondary outcomes included the following: number of needle insertion attempts, number of needle redirection times, actual epidural needle insertion depth, time taken to eastablish landmarks, time taken to perform the spinal anesthesia (the duration between local infiltration and bupivacaine injection), procedure time (the duration from sterilizing the back to converting into supine position), total time (the sum of the time to establish landmarks and the procedure time), adverse events during the procedure and anesthesia related complications. Results: A total of 191 patients successfully received combined spinal-epidural anesthesia by resident anesthesiologists, 9 patients (7 patients in group LM vs 2 patients in group US) failed.The first-attempt success rate in group LM was 37.6%, while the first-attempt success rate in group US was 68.4%, the difference between the two groups was significant (χ2=18.112, P<0.01). In group LM, the number of needle insertion attempts and needle redirection attempts were 2(1, 3) and 5(3, 10), respectively. In group US, the number of needle insertion attempts and needle redirection attempts were 1(1, 2) and 3(0, 5), respectively.The differences in the number of needle insertion attempts and needle redirection attempts between the two groups were significant (Z=-4.132, -4.077, all P<0.01). In group US, the time spent on determining the insertion point, on puncture, on finishing the procedure and the total time were as the following: 2.8(2.6, 3.1), 2.5(1.8, 4.1), 7.8(6.5, 8.9), 10.6(9.5, 11.9) min.In contrast, in group LM, those indices were as the following: 0.4(0.3, 0.4), 4.1(2.2, 6.3), 8.8(7.5, 11.4), 9.2(7.8, 11.9) min.There were significant differences in the above factors between the two groups (Z=-11.931, -4.025, -3.550, -3.290, all P<0.01). The paramedian sagittal oblique scanning image was superior to that of the transverse median plane. Conclusions: For elderly patients, ultrasound imaging before neuraxial block increases first-attempt success rate, decreases puncture time.The strengths of prepuncture ultrasound scanning outweighs its longer total time.

Abstract
Objective: To investigate the feasibility and diagnostic value of preoperative transthoracic echocardiography guided three dimensional printing model (TTE Guided 3DPM) on the assessment of structural heart disease (SHD). Methods: From February 2016 to October 2016, 44 patients underwent cardiac surgery in Tianjin Chest Hospital, forty-four patients were assessed preoperatively using TTE Guided 3DPM, including 25 males and 19 females, aged 3-75 years, with an average of (44±22) years. compared to conventional three dimensional transthoracic echocardiography (3D-TTE), and took direct intraoperative findings as "Golden Standard" simultaneously. There are twelve patients with SHD, including four cases with mitral prolapse, two cases with partial endocardial cushion defect, two cases with secondary atrial septal defect, two cases with rheumatic mitral stenosis, one case with tetralogy of Fallot, one case with ventricular septal defect (VSD), thirty-two patients without SHD were designed as negative control. Results: The sensitivity and specificity of TTE Guided 3DPM were greater than or equal to 3D-TTE, P value of McNemar test of 3D-TTE was greater than 0.05, the difference was not statistically significant, kappa=0.745, P<0.01, indicated that the results of 3DTTE and the gold standard were generally consistent.P value of McNemar test of TTE Guided 3DPM was greater than 0.05, the difference was not statistically significant, kappa=0.955, P<0.01, indicated that the results of TTE Guided 3DPM and gold standards were consistent. Compared with 3D-TTE and TTE Guided 3DPM, P value was greater than 0.05, the difference was not statistically significant, kappa=0.879, P<0.01, indicated that the results of 3D-TTE and TTE Guided 3DPM were consistent. TTE Guided 3DPM displayed the three-dimensional structure of SHD cardiac lesions clearly, which were consistent with intraoperative findings. Conclusion: TTE Guided 3DPM provides essential information for the preoperative evaluation and decision of SHD.
