Abstract
Pullorum disease caused by Salmonella Pullorum is one of the most important infectious diseases in the poultry industry worldwide, which leads to serious economic losses in many developing countries because of its high mortality rate in young chicks. The traditional slide agglutination test with low cost, fast reaction, and on-site detection has been widely used in the diagnosis of Pullorum disease. However, in practice, the test performance is with the disadvantages of false positive results and unstable detection results. In this paper, we developed self-made agglutination antigens prepared by local isolates in the poultry farm and compare the detection performance with commercial agglutination antigens (China Institute of Veterinary Drug Control) and Group D Salmonella ELISA kit (BioChek UK Ltd). The results of detecting 200 serum samples indicated that the consistency of commercial agglutination antigen detecting in 2 times was only 79.5%. Using the ELISA kit as the reference method, the commercial agglutination antigen detecting results of the Kappa test were only moderately consistent (0.58 ∼ 0.59). Meanwhile, positive and total coincidence rates of the self-made agglutination antigen test with more reliable repeat could reach 97.4 and 88%, respectively, and the result of Kappa test was highly consistent (0.75). The Receiver Operating Characteristic curve analysis clarified that the area under the receiver-operating-characteristic curve values of self-made and commercial agglutination antigen tests could reach 0.861 and 0.804, respectively. These results were coincident when detecting known positive serum from the infected chickens. It's worth mentioning that the visible positive reaction of self-made agglutination antigen test appeared faster and stronger than commercial antigen test. In conclusion, self-made Salmonella Pullorum agglutination antigen developed in this study was much better than commercial agglutination antigen and is expected to be a valuable tool in the diagnosis of the epidemiology of Salmonella Pullorum.

Abstract
A partial-wave analysis is performed for the process e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0} at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of e^{+}e^{-} collisions, collected by the BESIII detector at the BEPCII collider with a total integrated luminosity of 300 pb^{-1}, are analyzed. The total Born cross sections for the process e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0}, as well as the Born cross sections for the subprocesses e^{+}e^{-}→ϕπ^{0}π^{0}, K^{+}(1460)K^{-}, K_{1}^{+}(1400)K^{-}, K_{1}^{+}(1270)K^{-}, and K^{*+}(892)K^{*-}(892), are measured versus the center-of-mass energy. The corresponding results for e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0} and ϕπ^{0}π^{0} are consistent with those of BABAR with better precision. By analyzing the cross sections for the four subprocesses, K^{+}(1460)K^{-}, K_{1}^{+}(1400)K^{-}, K_{1}^{+}(1270)K^{-}, and K^{*+}(892)K^{*-}(892), a structure with mass M=(2126.5±16.8±12.4) MeV/c^{2} and width Γ=(106.9±32.1±28.1) MeV is observed with an overall statistical significance of 6.3σ, although with very limited significance in the subprocesses e^{+}e^{-}→K_{1}^{+}(1270)K^{-} and K^{*+}(892)K^{*-}(892). The resonant parameters of the observed structure suggest it can be identified with the ϕ(2170), thus the results provide valuable input to the internal nature of the ϕ(2170).

Abstract
In this study, we investigated the effect of intergroup contact on processing of own- and other-race faces using functional Magnetic Resonance Imaging (fMRI). Previous studies have shown a neural own-race effect with greater BOLD response to own race compared to other race faces. In our study, white participants completed a social-categorization task and an individuation task while viewing the faces of both black and white strangers after having answered questions about their previous experiences with black people. We found that positive contact modulated BOLD activity in the right fusiform gyrus (rFG) and left inferior occipital gyrus (lIOC), regions associated with face processing. Within these regions, higher positive contact was associated with higher activity when processing black, compared to white faces during the social categorisation task. We also found that in both regions a greater amount of individuating experience with black people was associated with greater activation for black vs. white faces in the individuation task. Quantity of contact, implicit racial bias and negatively valenced contact showed no effects. Our findings suggest that positive contact and individuating experience directly modulate processing of out-group faces in the visual cortex, and illustrate that contact quality rather than mere familiarity is an important factor in reducing the own race face effect.

Abstract
Objective: To evaluate the feasibility and safety percutaneous pulmonary vein intervention in patients with severe pulmonary vein stenosis (PVS) caused by fibrosing mediastinitis(FM). Methods: This retrospective analysis included 5 FM patients (2 male, 3 female, 54-77 years old) confirmed by clinical presentation and chest computed tomography (CT) scan from January to June 2018 who were from Gansu Provincial Hospital and Shanghai Chest Hospital. CT pulmonary angiography (CTPA) further revealed severe PVS caused by fibrotic tissue compression in mediastinum. After selective pulmonary vein angiography, gradually balloon angioplasty was used to expand the pulmonary vein and then stents were implanted in the pre-dilated stenotic pulmonary veins. Evaluation of therapeutic effect was made at 6 months after the procedure. Results: All of 11 serious compression PVS were treated with stent implantation (diameter: 7-10 mm, length: 17-27 mm). After stenting, degree of pulmonary vein stenosis decreased from (83±16)% to (12±4)% (P<0.01). The minimal diameter of the stenotic pulmonary vein was significantly increased from (0.8±0.5)mm to (7.5±0.8)mm (P<0.01). Trans-stenotic gradient decreased from (27.0±15.1)mmHg (1 mmHg=0.133 kPa) to (2.50±0.58)mmHg (P<0.05). Mean pulmonary pressure measured by cardiac catheter decreased from (45.0±9.0)mmHg to (38.7±8.4)mmHg (P<0.05). One patient experienced cardiac arrest due to vagal nerve reflex during big sizing balloon stent dilation and recovered after cardiopulmonary resuscitation. There were no other serious procedure related complications. During the follow-up, severe stenosis at end of proximal stent was evidenced in 1 patient due to fibrotic compression, and another patient developed in-stent thrombosis due to discontinuation of prescribed anticoagulant. Conclusion: Percutaneous intervention for severe pulmonary vein stenosis caused by FM is feasible and safe, and can improve hemodynamic caused by the compression of mediastinal vascular structures in these carefully selected patients.

Abstract
Abstract
Background
Recent preclinical research has suggested that combined use of radiofrequency-ablation and balloon-dilation (CURB) had the potential to create a stable inter-atrial communication. However, the related clinical data is still absent.
Purpose
This study describes the first-in-man use of CURB in the patients with severe pulmonary arterial hypertension (PAH).
Methods
Under the guidance of fluoroscopy and intra-cardiac echocardiography, CURB was attempted in 3 patients with severe PAH (age: 35.0±12.1 years, one idiopathic PAH and two PAH related to repaired congenital heart disease). With the aid of 3D location system, fossae ovalis was ablated with radiofrequency. Then the graded balloon-dilation was performed after transseptal puncture, and radiofrequency-ablation was repeated around the rim of fenestration created with balloon-dilation. The exercise capacity and fenestration-size were followed up.
Results
CURB was performed successfully in all 3 patients, and pulmonary vascular resistance was 30.3±10.9 Wood units. The fenestration size was 5.0±1.0 mm (range: 4–6 mm), and systemic arterial oxygen saturation decreased by 4.7±0.6% (range: 4–5%). World Health Organization functional class increased by 1.6±0.5 (P<0.001) and cardiac index increased by 0.58±0.34 L/min/m2 (P<0.001). In addition, exercise capacity improved significantly (+63.7 meters, P<0.001). Follow-up (6.0±1.0 months; range: 5–7 months) showed that all fenestrations were stable (P=0.808), and no complication occurred.
Figure 1. The combined use of radiofrequency-ablation and balloon-dilation (CURB) was performed in the patient with severe PAH. Left figures showed the procedure of CURB. Middle figures showed the created fenestration with MSCT, and the morphology and size of fenestration was provided in the right-inferior panel. In addition, the sizes of right atrium and ventricle were alleviated with increase of left atrium. Right figures indicated that the fenestration-size was stable during follow-up (one week, one month and six months, respectively).
Conclusions
In patients with severe PAH, CURB is feasible and effective to create a stable inter-atrial communication. Further research was required to evaluate the long-term result of this novel approach.

Abstract
The precise measurement of the spectrum of protons, the most abundant component of the cosmic radiation, is necessary to understand the source and acceleration of cosmic rays in the Milky Way. This work reports the measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE). This is the first time that an experiment directly measures the cosmic ray protons up to ~100 TeV with high statistics. The measured spectrum confirms the spectral hardening at ~300 GeV found by previous experiments and reveals a softening at ~13.6 TeV, with the spectral index changing from ~2.60 to ~2.85. Our result suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.

Abstract
BACKGROUND Leptin and insulin resistance have been pointed out to play a role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Increasing genes were shown to be associated with the risk of NAFLD. OBJECTIVE The study aimed to investigate the genetic association between two leptin receptor (LEPR) polymorphisms (Q223R and K109R) and the NAFLD risk. METHODS Studies were retrieved and included by using PubMed, Web of Science, the Cochrane Library databases, Chinese National Knowledge Infrastructure (CNKI) and EMBASE database. Genetic associations were assessed with pooled odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Five case-control studies with 1711 NAFLD patients and 1732 healthy controls were included in this meta-analysis. The K109R was significantly associated with NAFLD in allelic model in Southeast Asian subgroup (p=0.01, OR=0.59, 95% CI [0.39- 0.90]), but not in Chinese subgroup (p=0.24, OR=1.10, 95% CI [0.94-1.29]). The Q223R was significantly associated with NAFLD in both allelic and recessive models (allelic model: p<0.001, OR=0.57, 95% CI [0.50-0.65]; recessive model: p=0.001, OR=0.67, 95% CI [0.52-0.85]). However, subgroup analysis showed that the significant association between Q223R and NAFLD in allelic model cannot be found in Southeast Asians subgroup (p=0.07, OR=0.67, 95% CI [0.52-0.85]). CONCLUSION LEPR K109R might be a susceptible factor for NAFLD in Southeast Asian population. And LEPR Q223R might be a susceptible factor for NAFLD in Chinese population.

Abstract
Objective: To investigate the expression of programmed death 1(PD-1) and programmed death ligand 1 (PD-L1) on T lymphocyte and monocyte from peripheral blood of advanced non-small-cell lung cancer (NSCLC) patients and its potential role in immune escape of NSCLC. Methods: Forty-eight patients with advanced NSCLC (Lung Cancer Group) were included from the Department of Respiratory Diseases in The Second Affiliated Hospital of Soochow University from June 2014 to June 2015. Thirty-six healthy volunteers who received health examination at the same time, matching in sex, age were also enrolled as controls. The expression of PD-1 on peripheral blood CD4(+)T cells and CD8(+)T cells and PD-L1 on monocytes were detected by flow cytometry. Patients who received chemotherapy alone for 2-4 cycles and received sequential sampling were assessed with Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). Seven cases of patients with significant response to treatment were selected as partial response (PR) group and ten patients with poor response to treatment were treated as progression disease(PD) group. The differences in the expression of PD-1 on the surface of CD4(+)T cells, CD8(+)T cells, and PD-L1 on the surface of monocyte before and after treatment were analyzed. Results: Compared with healthy control group, PD-1 expression level on both CD4(+) T and CD8(+) T cells from peripheral blood in lung cancer group were significantly increased [(25.9±7.4)% vs (20.6±6.2)%, (19.9±9.8)% vs (14.0±5.6)%, both P<0.05]. A higher level of PD-L1 expression on monocyte in lung cancer group was also found compared with the control group [(33.1±15.1)% vs (13.6±5.3)%, P<0.001]. The expression level of PD-1 on CD4(+)T and CD8(+)T cells and PD-L1 on monocytes in lung cancer group with good response to treatment was relatively lower than the baseline level of before treatment [(22.8±8.5)% vs (25.9±7.8)%, (17.1±8.4)% vs (20.4±8.6)%, (18.1±6.9)% vs (31.3±13.2)%, all P<0.05], but in lung cancer group with poor response to treatment, it was higher than the baseline level of before treatment [(33.5±6.5)% vs (23.9±4.2)%, (25.2±9.1)% vs (19.1±8.8)%, (43.1±18.3)% vs (29.7±10.6)%, all P<0.05]. Conclusion: Abnormal expression of PD-1 and PD-L1 exists in T cells and monocytes respectively, prompting PD-1/PD-L1 pathway may inhibit T cell proliferation during the interaction of T cell and monocyte, which may lead to non-small cell lung cancer immune escape.

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 study the influence of the ear canal and middle ear cavity on air conduction and bone conduction. Method:A finite element model of the human middle ear was established. By establishing the external ear canal and the middle ear cavity, we evaluated the effects of the external canal and the middle ear cavity on air conduction and bone conduction. Result:In air conduction, the external canal improved the stapes response at the frequency range of 0.5 kHz to 6 kHz, and the maximum increase was 11 dB at 3 kHz. The middle ear cavity mainly reduced the response of stapes at mid-low frequency, with the drops of 2-4 dB under 2 kHz; in bone conduction, ear canal slightly reduced the low-frequency response, but increased the response of the stapes at the mid-high frequency, with a maximum increase of 1.9 dB at 1.5 kHz. The middle ear cavity mainly increased the stapes response at mid-frequency near 1.5 kHz, with a maximum increase of 2.5 dB. Conclusion:Our results show that, in air conduction, the ear canal significantly increases the middle-frequency response, while the middle ear cavity decreases the low-mid frequency response. Whereas, the ear canal and the middle ear cavity have slightly effect on bone conduction.

Abstract
Abstract
Background: Leukemia inhibitory factor (LIF) and its receptor LIFR are over-expressed in multiple solid tumors and play a key role in tumor growth, progression, and resistance to standard anti-cancer treatments. Triple-negative breast cancer (TNBC) lacks targeted therapies and represents a disproportional share of breast cancer (BCa) mortality. TNBC exhibits autocrine stimulation of the LIF/LIFR axis and overexpression of LIF is associated with poorer relapse-free survival in BCa patients. LIF signaling also promotes maintenance of stem cells. Therefore, targeting the LIF/LIFR axis may have therapeutic utility in TNBC.
Methods: We rationally designed a small organic molecule (EC359) that emulates the LIF/LIFR binding site and functions as a LIFR inhibitor from a library of compounds. In silico docking studies were used to identify the putative interaction of the EC359 and LIF/LIFR complex. Direct binding of EC359 to LIFR was confirmed using surface plasmon resonance (SPR) and microscale thermophoresis technique (MST) assays. In vitro activity was tested using Cell-Titer Glo, MTT, invasion, and apoptosis assays. Mechanistic studies were conducted using Western blot, reporter gene assays, and RNA-seq analysis. Xenograft, patient-derived xenograft (PDX), and patient-derived explant (PDEX) models were used for preclinical evaluation and toxicity.
Results: Molecular docking studies showed that EC359 interacts at the LIF/LIFR binding interface. SPR and MST studies confirmed direct interaction of EC359 to LIFR. EC359 reduced the growth of TNBC cells with high potency (IC50 50-100nM) and promoted apoptosis. Further, EC359 treatment reduced invasion and stemness of TNBC cells. EC359 activity is dependent on the expression levels of LIFR and showed little or no activity on TNBC cells that have low levels of LIFR or ER+ve BCa cells. Further, EC359 significantly reduced the viability of cisplatin and taxane-resistant TNBC cells and enhanced the efficacy of HDAC inhibitors. Mechanistic and biochemical studies showed that EC359 interacts with LIFR and effectively blocking LIF/LIFR interactions. EC359 also blocked LIFR interactions with other LIFR ligands such as oncostatin M, ciliary neurotrophic factor, and cardiotrophin-1. EC359 treatment attenuated the activation of LIF/LIFR driven pathways including STAT3, mTOR, AKT, and MAPK. RNA-seq analysis identified regulation of apoptosis as one of the important pathway modulated by EC359. In TNBC xenograft and PDX assays, EC359 significantly reduced tumor progression. Further, using human primary BCa PDEX cultures, we demonstrated that EC359 has the potential to substantially reduce the proliferation of human BCa. Pharmacologically, EC359 exhibited high oral bioavailability and long half-life with a wide therapeutic window.
Conclusions: EC359 is a novel targeted therapeutic agent that inhibits LIF/LIFR oncogenic signaling in TNBC via a unique mechanism of action. EC359 has the distinct pharmacologic advantages of oral bioavailability, in vivo stability, and is associated with minimal systemic side effects. (DOD BCRP grant #BC170312)

Abstract
Abstract
Objectives: Upper extremity dysfunction (UED) is a known side effect of breast cancer treatment. It is unclear, however, to what degree radiation contributes to this morbidity. We aimed to characterize the level of UED using patient-reported outcomes (PROs) prior to, during, and after treatment with radiation for breast cancer. Our secondary aims were to evaluate the association of UED with pain scores.
Methods: This is a single-institution, prospective, longitudinal cohort study of patients treated with radiation for breast cancer. The validated patient-reported outcome measure, Quick Disabilities of the Arm, Shoulder and Hand (QD) was used to capture UED prior to radiation, at the end of radiation, and 1 month following the completion of radiation. Pain scores were also collected at these intervals using the numeric pain reporting scale (NPRS) from 0 (no pain) to 10 (worst pain).
Results: Forty-four patients were enrolled on this study and 43 (97.7%) had completed radiation at the time of analysis. Thirteen patients (29.5%) were treated with mastectomy, axillary lymph node dissection and regional nodal irradiation in the supine position. The other 31 (70.5%) patients underwent lumpectomy and sentinel lymph node biopsy. Of these patients, 26 (83.9%) were treated in the prone position and 30 (96.8%) received whole breast irradiation. Median time from surgery to radiation was 69 days (range 35 – 212 days), 76 days for mastectomy and 68 days for lumpectomy. Median time from start to end of radiation was 38 days for mastectomy and 28 days for lumpectomy. Pre-treatment median QD score prior to radiation was 12.5 (11.4 for lumpectomy, 15.9 for mastectomy), 9.1 at the end of radiation (9.1 for lumpectomy, 18.2 for mastectomy), and 2.4 at 1 month after radiation (2.3 for lumpectomy, 2.5 for mastectomy). Median NPRS scores at pre-treatment, post-treatment and 1 month follow-up were 1, 1, and 1 for lumpectomy and 0, 1, 0 for mastectomy patients, respectively.
Conclusion: In this initial pilot study with 1 month of follow up, patient-reported UED as demonstrated by QD scores were higher pre-radiation and decreased by one month after. This likely reflects recuperation after surgical procedure. Median average pain scores were low at all time points. Further evaluation of UED over time to characterize the long-term effect of radiation and correlation with quality of life and other clinical factors is planned.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE Retrospective comparison of radiographic and clinical outcomes between anterior spinal fusion (ASF) and posterior spinal fusion (PSF) in surgical treatment of Lenke 5 curves. SUMMARY OF BACKGROUND DATA ASF and PSF are used for treatment of Lenke 5 curves in patients with adolescent idiopathic scoliosis (AIS). Currently, no consensus exists for optimal surgical treatment of Lenke 5 curves. METHODS Patients with Lenke 5 curves treated with either ASF or PSF were prospectively enrolled in a multicenter database and then retrospectively reviewed. Demographic data, perioperative measures, radiographic data, and SRS-22R scores were collected and compared for statistical significance. RESULTS A total of 149 patients were included in the study; 51 underwent PSF and 98 underwent ASF. There was no difference in demographics between groups. The PSF group was fused one level longer than the ASF group (5.9 levels PSF, 4.6 levels ASF, p < .0001). The PSF group had shorter operative times (223 minutes PSF, 297 minutes ASF; p < .0001) and a higher proportion of patients who received a postoperative blood transfusion (45% vs. 5%, p < .0001). PSF patients had longer hospital stays (6.1d PSF vs. 5d ASF, p = .031). The ASF group had larger preoperative major curve (48.2° ASF, 44.2° PSF; p < .01). Coronal balance, thoracolumbar/lumbar Cobb angle, shoulder height, trunk shift, and overall sagittal balance were not different between groups at two-year follow-up. Curve correction at two-year follow-up was similar between groups (66% ASF vs. 62% PSF). There were no significant differences in clinical outcomes or complication rates between groups. CONCLUSION There is no difference in radiographic or clinical outcomes in patients treated with ASF or PSF for Lenke 5 curves. ASF may save a fusion level, but has longer operative time than PSF. Ultimately, the risks and benefits of each approach merit consideration by surgeon and patient. LEVEL OF EVIDENCE Level II.

Abstract
Canine diffuse large B-cell lymphoma (DLBCL), the most common hematologic malignancy of dogs, is associated with poor overall survival. The lack of conventional chemotherapies with sustainable efficacy warrants investigation of novel therapies. Pevonedistat (MLN4924) is a potent and selective small molecule NEDD8-activating enzyme inhibitor. In human activated B-cell-like (ABC) diffuse large B-cell lymphoma, pevonedistat induces lymphoma cell apoptosis, DNA damage and G1 cell cycle arrest by inhibiting the nuclear factor-κB (NF-κB) pathway. Genomic and transcriptomic studies showed that the NF-κB pathway is deregulated in canine DLBCL. Our results showed that pevonedistat treatment significantly reduces the viability of canine DLBCL cells by inducing G1 cell cycle arrest and apoptosis. Pevonedistat treatment inhibits NF-κB pathway activation and downregulates NF-κB target genes in canine DLBCL. Moreover, administration of pevonedistat to mice bearing canine DLBCL xenograft tumours resulted in tumour regression. Our in vivo and in vitro studies provide justification for future clinical application of pevonedistat as a potential new anti-cancer therapy that may benefit both canine and human species.

Abstract
Objective: To analyze the expression of soluble programmed death ligand 1 (sPD-L1) in the serum of patients with advanced epidermal growth factor receptor (EGFR) mutated lung adenocarcinoma and to explore its clinical implications. Methods: Seventy-two patients with EGFR mutated advanced lung adenocarcinoma (EGFR mutation group) were included from the Department of Respiratory Diseases in The Second Affiliated Hospital of Soochow University from May 2015 to July 2016. Thirty-one patients with advanced EGFR wild type (WT) lung adenocarcinoma [EGFR WT group, diagnosed via mini specimens from bronchoscopy or transthoracic needle aspiration biopsy (TNAB), matching in sex, age and tumor stage with EGFR mutation group] were also enrolled as controls. The sPD-L1 protein expression in serum was determined by enzyme-linked immunosorbent assay (ELISA) kit. According to the clinical response of two-month EGFR-tyrosine kinase inhibitor (TKI) treatment, all patients were divided into two groups: 36 cases in disease progression groups (PD group) and 36 cases in disease control group (DC group). The sPD-L1 level in peripheral blood between the two groups was analyzed. In EGFR mutation group, the relationship of serum sPD-L1 with TNM staging was analyzed. At the same time, the value of serum sPD-L1 and cancer embryo antigen (CEA) in clinical evaluation of advanced EGFR mutated lung adenocarcinoma was evaluated by analyzing the receiver operating characteristic (ROC) curve. Results: A lower level of sPD-L1 level in EGFR mutation group [0.75(0.15-2.78) μg/L] was found compared with the control group [1.56(0.85-3.29) μg/L] (P<0.001). The expression of sPD-L1 in PD group was significantly higher than that in DC group [1.175(0.62-2.78) μg/L vs 0.625(0.15-2.27) μg/L, P<0.001]. High expression of sPD-L1 in the serum of patients with advanced EGFR mutated lung adenocarcinoma was closely correlated to lymph node metastasis and distant metastasis (χ2=10.985, 4.662; both P<0.05). The area under ROC curve of serum sPD-L1 and CEA was 0.893 (95%CI: 0.830-0.956) and 0.745(95%CI: 0.652-0.839) respectively. Youden index was the maximum when the cutoff value of sPD-L1 was set to 0.815 μg/L, and the sensitivity and specificity were 77.8% and 91.4%, respectively. Conclusions: After EGFR-TKI treatment, the level of sPD-L1 in the serum of patients with advanced EGFR mutated lung adenocarcinoma is lower, which suggests that sPD-L1 expression may depend on the regulation of EGFR signaling pathway. The level of sPD-L1 can reflect the clinical response of EGFR mutated lung adenocarcinoma to EGFR-TKI.

Abstract
RUNX1 is absolutely required for definitive hematopoiesis, but the function of RUNX1b/c, two isoforms of human RUNX1, is unclear. We established inducible RUNX1b/c-overexpressing human embryonic stem cell (hESC) lines, in which RUNX1b/c overexpression prevented the emergence of CD34+ cells from early stage, thereby drastically reducing the production of hematopoietic stem/progenitor cells. Simultaneously, the expression of hematopoiesis-related factors was downregulated. However, such blockage effect disappeared from day 6 in hESC/AGM-S3 cell co-cultures, proving that the blockage occurred before the generation of hemogenic endothelial cells. This blockage was partially rescued by RepSox, an inhibitor of the transforming growth factor (TGF)-β signaling pathway, indicating a close relationship between RUNX1b/c and TGF-β pathway. Our results suggest a unique inhibitory function of RUNX1b/c in the development of early hematopoiesis and may aid further understanding of its biological function in normal and diseased models.

Abstract
Osteoporosis is a systemic skeletal disorder characterized by reduced bone mass and deterioration of bone microarchitecture, which results in increased bone fragility and fracture risk. Casein kinase 2-interacting protein-1 (CKIP-1) is a protein that plays an important role in regulation of bone formation. The effect of CKIP-1 on bone formation is mainly mediated through negative regulation of the bone morphogenetic protein pathway. In addition, CKIP-1 has an important role in the progression of osteoporosis. This review provides a summary of the recent studies on the role of CKIP-1 in osteoporosis development and treatment.

Abstract
AIM To explore the role of computed tomography (CT) texture analysis in predicting pathologic stage of gastric cancers. MATERIALS AND METHODS Preoperative enhanced CT images of 153 patients (112 men, 41 women) with gastric cancers were reviewed retrospectively. Regions of interest (ROIs) were manually drawn along the margin of the lesion on the section where it appeared largest on the arterial and venous CT images, which yielded texture parameters, including mean, maximum frequency, mode, skewness, kurtosis, and entropy. Correlations between texture parameters and pathological stage were analysed with Spearman's correlation test. The diagnostic performance of CT texture parameters in differentiating different stages was evaluated using receiver operating characteristic (ROC) analysis. RESULTS Maximum frequency in the arterial phase and mean, maximum frequency, mode in the venous phase correlated positively with T stage, N stage, and overall stage (all p<0.05) of gastric cancer. Entropy in the venous phase also correlated positively with N stage (p=0.009) and overall stage (p=0.032). Skewness in the arterial phase had the highest area under the ROC curve (AUC) of 0.822 in identifying early from advanced gastric cancers. Multivariate analysis identified four parameters, including maximum frequency, skewness, entropy in the venous phase, and differentiation degree from biopsy, for predicting lymph node metastasis of gastric cancer. The multivariate model could distinguish gastric cancers with and without lymph node metastasis with an AUC of 0.892. CONCLUSION Multiple CT texture parameters, especially those in the venous phase, correlated well with pathological stage and hold great potential in predicting lymph node metastasis of gastric cancers.

Abstract
BACKGROUND The subgroup of young patients with non-small-cell lung cancer (NSCLC) is poorly understood. We retrospectively studied the clinical characteristics, gene mutations, and outcomes of patients with NSCLC (aged ≤ 40 years). RESULTS Of the 7494 patients with lung cancer diagnosed from February 2001 to October 2016, 252 aged ≤ 40 years showed NSCLC. We divided their cases into non-squamous cell carcinoma and squamous cell carcinoma groups according to their histology results. Of the 252 young NSCLC patients, 173 (69%) patients had stage IIIB or IV, and 196 (78%) had never smoked. The four most common metastases were intrapulmonary lesions, pleura, bone, and brain. Among patients with adenocarcinoma, 29 (40%, n = 73) harbored epidermal growth factor receptor (EGFR) mutations, 25 (34%, n = 74) harbored anaplastic lymphoma kinase (ALK) translations, and 1 (14%, n = 7) harbored ROS proto-oncogene 1 receptor tyrosine kinase (ROS1) translations. The median progression-free survival (PFS) and overall survival (OS) were 3.3 and 27.6 months for patients receiving chemotherapy (n = 65), and 12.1 and 33.6 months for patients receiving EGFR tyrosine kinase inhibitors (TKIs) (n = 13), respectively. Patients receiving crizotinib had a median PFS time of 21.9 months (n = 8). CONCLUSIONS Young patients are associated with an increased likelihood of gene mutations and can receive a better prognosis when patients harboring gene mutations are treated with EGFR-TKIs or ALK inhibitors.

Abstract
Abstract
Background: Many breast cancer (BC) patients, particularly those who receive chemotherapy (chemo), experience affective symptoms and cognitive changes that can negatively impact their quality of life. Causal links between inflammatory mediators and the development of depressive-like behavior and cognitive defects, have been established in mouse models, including studies by our group showing increased microglial activation following chemo (A.C DeVries et al). Microglia are resident immune cells of the brain, which release proinflammatory cytokines when activated. Doxorubicin (DOX) induces microglial activation in the brain. Minocycline, a second generation tetracycline, has been shown to suppress inflammation by inhibiting microglial activation in CNS disease models. We hypothesize that (1) chemo activates microglia in the brains of women being treated for BC, which can precipitate or exacerbate depression, anxiety and cognitive deficits and (2) Minocycline administration during neoadjuvant or adjuvant chemo will prevent chemo-induced microglial activation and will reduce affective and cognitive symptom burden. Trial Design: This is a single center, Phase II, double blinded randomized study of minocycline (100 mg twice a day) vs placebo twice a day in women with BC receiving DOX-based or other chemo for BC. Pts will be randomized to either oral minocycline or placebo for up to a 1 week loading period plus chemo treatment period and an optional subsequent 2 week period. Eligibility Criteria: Women diagnosed with BC stages I-III initiating first line adjuvant or neoadjuvant chemo. Aims: (1) to evaluate symptoms related to anxiety and depression and cognitive changes during and after chemo completion (2) to evaluate markers of neuro inflammation as assessed by blood based inflammatory cytokines and central markers of inflammation and microglia activation using 1 F-Fludeoxyglucose and 11C-PK11195 positron emission tomography. Primary endpoints are changes in Center for Epidemiological Studies Depression Scale (CES-D) and State Trait Anxiety Index (STAI) from baseline to end of study after minocycline vs placebo intervention. Secondary endpoints are changes in cognitive function during chemo using validated cognitive testing including N-Back Test, Behavioural Rating Inventory of Executive Function (BRIEF) and the Multifactorial Memory Questionnaire Ability Scale (MMQ). Statistical Methods: Primary analysis for efficacy will be intention-to-treat. The main objective is to preliminarily evaluate the effect of minocycline on chemo-induced depressive symptoms in terms of changes in CES-D and STAI scores. Mixed models will be used to evaluate cognitive function changes. A sample size of 23 per group, will give 80% power to detect an effect size of 0.74 standard deviation (SD) difference between the 2 groups at significance level of 0.10 based on a 2 sided two-sample t-test. From our experience, attrition of less than 20% is expected for studies in this patient population in our center, and to account for this, we plan to recruit up to 60 patients. 16 of 46 evaluable pts have been accrued to date. Accrual started in January 2016. Funded by Pelotonia grant from The OSUCCC. Contact: Study PI: Maryam.lustberg@osumc.edu

Abstract
BACKGROUND AND AIMS Recent studies suggested that circulating fibroblast growth factor (FGF) 19 levels might be associated with the fat content and distribution, and varied with different glucose tolerance status. This study aimed to investigate the association of serum FGF19 levels with obesity and visceral fat accumulation in a Chinese population with differing glucose tolerance status. METHODS AND RESULTS The 2383 participants were divided into subgroups of glucose tolerance status: normal glucose tolerance (NGT, n = 1754), impaired glucose regulation (IGR, n = 499), and newly diagnosed diabetes mellitus (DM, n = 130). They were further stratified into quartiles of serum FGF19 levels (Q1-Q4). Visceral fat area (VFA) and subcutaneous fat area were measured using magnetic resonance imaging. FGF19 were detected via quantitative sandwich enzyme-linked immunosorbent assay. Serum FGF19 levels showed a downtrend across the NGT, IGR, and DM groups (P for trend = 0.016). VFA was an independent and negative factor of serum FGF19 levels (standardized β = -0.108, P = 0.001). After adjustment for glucose tolerance status, VFA differed significantly among FGF19 quartiles (P < 0.001), showing a downtrend from Q1-Q4. The associations of serum FGF19 levels and glucose tolerance status with VFA were independent of each other. After adjustment for insulin resistance and secretory function separately, VFA still decreased significantly from Q1-Q4 (all P < 0.001). CONCLUSION Serum FGF19 levels were related to visceral fat accumulation. Independent of glucose tolerance status, serum FGF19 levels were inversely associated with VFA.

Abstract
In transplantation medicine, the embryo complementation method has been introduced as a possible means to produce an organ derived from the desired cells. Previously, our laboratory demonstrated that the transcription factor Ets variant 2 (Etv2) regulates hematoendothelial lineage differentiation. In this study, ETV2-null pig fibroblasts were generated using the CRISPR/Cas9 system, and these cells were utilised as donor cells for porcine somatic cell nuclear transfer (SCNT) to produce mutant embryos. After transplantation of these mutant embryos into 4 surrogate gilts, 12 fetuses were found in 2 gilts at E-18. Eight of those embryos lacked hematoendothelial lineages, were nonviable, and lacked ETV2 by PCR analysis. To rescue the hematoendotheilal phenotypes, the blastomeres were collected from green fluorescent protein (GFP)-expressing embryos, which were generated by SCNT with the pig GFP-fibroblasts. Then, the GFP-blastomeres were injected into the ETV2-null SCNT embryos (4 GFP-blastomeres per a complementation on average) at the morula stage. These complemented embryos were transferred into 4 surrogate gilts. Two surrogate gilts were not pregnant, but 2 pregnant gilts harbored complemented fetuses. Complemented fetuses were evaluated at E26 and had intact and fully complemented hematoendothelial lineages, which were confirmed by CFU-assays, fluorescence-activated cell sorting (FACS), qPCR, and immunohistochemistry. Importantly, the hematoendotheilal lineages completely expressed GFP. In the complemented fetuses, the GFP-positive cells were observed throughout the body at more than 70%. These studies provide a platform for the in vivo production of functional hematoendothelial tissues from pluripotent stem cells (such as human pluripotent cells) using the embryo complementation technique.

Abstract
Objective: To evaluate the feasibility of susceptibility weighted imaging (SWI) to reflect the progression of renal fibrosis (RF) induced by unilateral ureteral obstruction (UUO) in rabbits. Methods: Total of 32 New Zealand white rabbits (aged 4-5 months) were used to establish the UUO model (RF group) and were divided into 4 subgroups (including RF-2W group, RF-4W group , RF-6W group and RF-8W group) according to the duration of obstruction(2, 4, 6 and 8 weeks). Another 8 rabbits, underwent sham operation, were used as the control group (Sham group). T2 weighted imaging (T(2)WI) and SWI sequences were performed on the rabbits at 2, 4, 6 and 8 weeks after UUO, respectively. Rabbits were sacrificed and specimens were obtained after MR examination, then hematoxylin&eosin staining and Masson staining were performed to explore the renal tubular injury and interstitial fibrosis. The relationship between the relative signal-to-noise ratio(rSNR)measured on the SWI fusion maps and the degree of renal fibrosis was analyzed. Analysis of variance was used to compare the difference of rSNRs among 5 groups. Results: The rSNRs of the inner medulla gradually decreased over time, the rSNRs of Sham group, RF-2W group, RF-4W group, RF-6W group and RF-8W group was 2.29±0.18, 1.73±0.30, 1.67±0.08, 1.42±0.28, 1.12±0.15, respectively (F=25.876, P<0.01). In RF-2W group, the rSNRs of the outer medulla and cortex increased when compared with those in the Sham group, then they decreased gradually over time in the other groups (F=5.230, 7.621, both P<0.05). The pathological results demonstrated that the morphology of renal tubules in Sham group was normal and no apoptosis or necrosis was seen in the tubular epithelial cells. In the RF-2W group, the main pathological manifestations included renal tubules dilatation, tubular epithelial cell degeneration or necrosis and the infiltration of inflammatory cell. In Masson staining, lots of blue areas were present in the interstitial. As the obstruction time prolonged, the renal tubular collapse, inflammatory cells and fibroblasts increased significantly. Meanwhile blue area also increased significantly in Masson staining. Conclusion: SWI can be used as a noninvasive method to evaluate the pathological progression of fibrosis in the rabbit UUO model.

Background The Janus Kinase (JAK) and Signal Transducer and Activator of Transcription (STAT) pathways play important roles in the pathogenesis of diffuse large B cell lymphoma (DLBCL) in humans, and up‐regulated STAT3 expression and activity are associated with worse clinical outcome in humans. No studies have evaluated the JAK‐STAT signaling pathway in DLBCL of dogs. Hypothesis STAT3 pathway is deregulated in DLBCL in dogs. We aim to assess the expression, activation, and cellular localization of STAT3 and mitogen‐activated protein kinase ERK1/2 in DLBCL of dogs. Animals Forty‐three client‐owned dogs diagnosed with DLBCL by histopathology Methods Retrospective analysis of DLBCL in dogs, including patient characteristics and treatment, immunohistochemistry, and protein expressions by Western blot. Results A higher percentage of STAT3 and p‐STAT3 immunolabelled cells were observed in DLBCL of dogs when compared to normal canine lymph nodes. In STAT3 immunolabelled cells, STAT3 has higher nuclear expression in lymphoma samples than in normal or reactive lymph nodes. In addition to up‐regulated STAT3 expression and activation, mitogen‐activated kinase ERK1/2 activation is up‐regulated in DLBCL of dogs. Conclusion and Clinical Importance Compared with the normal canine lymph node, DLBCL of dogs has up‐regulated STAT3 pathway. Our results support future investigation of JAK inhibitors in the treatment of DLBCL in dogs.

Clin Radiol 2017; 73:266-274. [PMID: 28969853 DOI: 10.1016/j.crad.2017.09.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2017] [Revised: 07/27/2017] [Accepted: 09/04/2017] [Indexed: 12/14/2022]
Abstract
AIM To explore the role of texture analysis of computed tomography (CT) images in predicting the malignancy risk of gastrointestinal stromal tumours (GISTs). MATERIALS AND METHODS Seventy-eight patients with histopathologically confirmed GISTs underwent preoperative CT. Texture analysis was performed on unenhanced and contrast-enhanced CT images, respectively. Fourteen CT texture parameters were obtained and compared among GISTs at different malignancy risks with one-way analysis of variance or independent-samples Kruskal-Wallis test. Correlations between CT texture parameters and malignancy risk were analysed with Spearman's correlation test. Diagnostic performance of CT texture parameters in differentiating GISTs at low/very low malignancy risk was tested with receiver operating characteristic (ROC) analysis. RESULTS Three parameters on unenhanced images (r=-0.268-0.506), four parameters on arterial phase (r=-0.365-0.508), and six parameters on venous phase (r=-0.343-0.481) imaging correlated significantly with malignancy risk of GISTs, respectively (all p<0.05). For identifying GISTs at low/very low malignancy risk, three parameters on unenhanced images (area under ROC curve [AUC], 0.676-0.802), four parameters on arterial phase (AUC, 0.637-0.811), and six parameters on venous phase (AUC, 0.636-0.791) imaging showed significant diagnostic performance, respectively (all p<0.05), especially maximum frequency on both unenhanced and contrast-enhanced images (AUC, 0.791-0.811). CONCLUSION Texture analysis of CT images holds great potential to predict the malignancy risk of GISTs preoperatively.

Abstract
Background Canine diffuse large B‐cell lymphoma (DLBCL) is a common and aggressive hematologic malignancy. The lack of conventional therapies with sustainable efficacy warrants further investigation of novel therapeutics. The Janus kinase (JAK) and signal transducer and activator of transcription (STAT) pathways play important roles in the pathogenesis of hematologic malignancies in humans including DLBCLs. AZD1480 and CYT387 are novel JAK1/2 inhibitors that have been used in clinical trials for treating various hematologic cancers in humans. No studies have characterized the antitumor effects of JAK inhibitors on DLBCL in dogs. Hypothesis/Objectives We hypothesize that JAK1/2 inhibitors AZD1480 and CYT387 can effectively inhibit growth of canine DLBCL in vitro. We aim to assess the antitumor activity of AZD1480 and CYT387 in canine DLBCL and to determine the underlying mechanisms of action. Methods In vitro study of canine lymphoma cell growth, proliferation, and apoptosis by viability, proliferation and apoptosis assays. Results A significant decrease in viable canine lymphoma cells was observed after AZD1480 and CYT387 treatments. In addition, AZD1480 and CYT387 treatment resulted in decreased lymphoma cell proliferation and increased early apoptosis. Conclusion and Clinical Importance AZD1480 and CYT387 inhibit canine lymphoma cell growth in a dose‐dependent manner. Our findings justify further phase I/II clinical investigations of the safety and efficacy of JAK1/2 inhibitors in canine DLBCL and suggest new opportunities for novel anticancer therapies.
