Abstract
Non-small cell lung cancer (NSCLC) is one of the most common and malignant carcinoma worldwide, and the incidence and mortality are increasing rapidly. Immunotherapy targeting programmed death 1/programmed death ligand 1 (PD-L1) signaling has shown prominent clinical effects in treating NSCLC; however, a poor understanding of the associated regulating molecular mechanisms of PD-L1 has become one of the biggest obstacles for further improving efficacy. Bridging integrator-1 (BIN1) can regulate numerous cancer-related molecules to exert multiple tumor-suppressing effects by either interacting or not interacting with c-MYC. In the present study, we observed that there exists a negative correlation between the expression of PD-L1 and BIN1 in NSCLC tissues. The expression levels of BIN1 and PD-L1 were significantly related to the tumor, lymph node and metastasis grade (TNM) stage, invasion range and lymph node metastasis. Simultaneously, for NSCLC patients, the expression statuses of BIN1 and PD-L1 might be independent prognostic factors. Furthermore, the expression of tumor-infiltrating lymphocytes was positively associated with BIN1 expression and negatively related to PD-L1 expression in NSCLC tissues. Importantly, we showed that PD-L1 was under the control of BIN1. In addition, the overexpression of BIN1 could inhibit the c-MYC and epithelial growth factor receptor (EGFR)-dependent PD-L1 expression and reverse the suppressive immuno-microenvironment in vivo. Taken together, our findings indicated that BIN1 restoration in NSCLC could reverse PD-L1-mediated immune escape by inactivating the c-MYC and EGFR/mitogen-activated protein kinase pathways.

Abstract
Larynx is a complicated organ of significant functions including breathing, voicing, protecting and so on, so it's important for anyone involved in the filed to know more about the multiple structures of the complex. Although there are numerous 2D images of larynx, it's still difficult for the observers to understand the organ well, so it's necessary to establish a real digital modal of larynx. With the development of computer and image processing technologies, medical imaging datasets have been used for the reconstruction of larynx. And the complete of visible human project also provides colorful cross-sectional images for reconstruction. The article reviews the development of the reconstruction of larynx, and predicts the possible developing direction of future 3D reconstruction.

Abstract
Aims To present our experience of using a combination of intra-articular osteotomy and external fixation to treat different deformities of the knee. Patients and Methods A total of six patients with a mean age of 26.5 years (15 to 50) with an abnormal hemi-joint line convergence angle (HJLCA) and mechanical axis deviation (MAD) were included. Elevation of a tibial hemiplateau or femoral condylar advancement was performed and limb lengthening with correction of residual deformity using a circular or monolateral Ilizarov frame. Results At a mean follow-up of 2.8 years (1.5 to 4.1), the mean HJLCA improved from 15.6° (10° to 23°) pre-operatively to 0.4° (0° to 2°). The mean MAD improved from 70.0 mm (20.1 to 118.5) pre-operatively to 9.1 mm (3 to 15). The mean tibiofemoral angle improved from 31.0° (8° to 54°) pre-operatively to 4.9° (2° to 8°). The mean limb-length discrepancy decreased from 6.3 cm (2.9 to 13.6) pre-operatively to 1.1 cm (0 to 5). All osteotomies and distraction zones healed without complications. Conclusion The use of intra-articular corrective osteotomies combined with the Ilizarov technique allowed correction of deformities of the knee joint with satisfactory HJLCA and overall mechanical axis in six patients with a good functional and cosmetic outcome in the short term.

Abstract
Episcleritis and scleritis are relatively rare ocular diseases, which are commonly associated with rheumatic diseases including systemic lupus erythematosus (SLE). To investigate clinical and laboratory features of SLE-associated episcleritis and scleritis, we now report 4 cases of inpatients who were diagnosed with episcleritis or scleritis secondary to SLE from September 2005 to July 2016 in the Department of Rheumatology and Immunology in Peking University People's Hospital. Demographic, clinical and laboratory characteristics were summarized together with the treatment regimen and the prognosis; the literature was reviewed. There were 3 female and 1 male patients. The average age was (49.0±23.8) years and the mean duration of SLE at the onset of episcleritis or scleritis was (2.1±1.4) years. In addition to the eye involvement, the patients had mucocutaneous manifestations, serositis, lupus nephritis and interstitial pneumonia simultaneously; in the past, 1 patient experienced arthritis, 2 presented Raynaud's phenomenon, and 2 had hematologic involvement. All the patients had antinuclear antibody (ANA) of high titer. The anti double-stranded DNA (ds-DNA) antibody titers were increased in 2 patients. Three patients had positive anti-nucleosome antibody (ANuA) while the other 1 patient did not test it. The complement levels were decreased in 3 patients. The systemic lupus erythematosus disease activity index (SLEDAI) scores were more than 4 points in all the patients (ranging from 7-16), suggesting active disease. Ocular symptoms included pain, redness of the eye and tears. Ophthalmic examinations revealed 3 cases of episcleritis and 1 case of scleritis. Among the 4 patients, 2 patients experienced ocular complications including decrease in vision and uveitis. All the patients were treated with systemic corticosteroids combined with hydroxycloroquine; 3 patients were treated with immunosuppressants (cyclophosphamide in 2 patients and leflunomide in 1 patient). All of the 4 patients received topical steroid and 1 patient received periocular injection of triamcinolone acetonide; 1 patient received topical nonsteroidal anti-inflammatory drug (NSAID).No recurrence of episcleritis or scleritis was observed during the follow-ups. As a conclusion, scleritis and episcleritis, although uncommon, may occur in patients with autoimmune rheumatic diseases including SLE. The occurrence of episcleritis and scleritis may suggest active disease of SLE. Ocular complications need to be aware of in the patients. Prompt diagnosis and treatment was associated with good visual outcomes in the follow-ups.

Abstract
BACKGROUND Signaling through histamine receptors on dendritic cells (DCs) may be involved in the effector phase of peanut-induced intestinal anaphylaxis. OBJECTIVES The objective of this study was to determine the role of histamine H1 (H1R) and H4 receptors (H4R) in intestinal allergic responses in a model of peanut allergy. METHODS Balb/c mice were sensitized and challenged with peanut. During the challenge phase, mice were treated orally with the H1R antagonist, loratadine, and/or the H4R antagonist, JNJ7777120. Bone marrow-derived DCs (BMDCs) were adoptively transferred to nonsensitized WT mice. Symptoms, intestinal inflammation, and mesenteric lymph node and intestine mucosal DCs were assessed. Effects of the drugs on DC chemotaxis, calcium mobilization, and antigen-presenting cell function were measured. RESULTS Treatment with loratadine or JNJ7777120 individually partially suppressed the development of diarrhea and intestinal inflammation and decreased the numbers of DCs in the mesenteric lymph nodes and lamina propria. Combined treatment with both drugs prevented the development of diarrhea and intestinal inflammation. In vitro, the combination suppressed DC antigen-presenting cell function to T helper cells and DC calcium mobilization and chemotaxis to histamine. CONCLUSION Blockade of both H1R and H4R in the challenge phase had additive effects in preventing the intestinal consequences of peanut sensitization and challenge. These effects were mediated through the limitation of mesenteric lymph node and intestinal DC accumulation and function. Identification of this histamine H1R/H4R-DC-CD4+ T-cell axis provides new insights into the development of peanut-induced intestinal allergic responses and for prevention and treatment of peanut allergy.

Abstract
Two-dimensional heterostructures with strong spin-orbit coupling have direct relevance to topological quantum materials and potential applications in spin-orbitronics. In this work, we report on novel quantum phenomena in [Pb2BiS3][AuTe2], a new 2D strong spin-orbit coupling heterostructure system. Transport measurements reveal the spin-related carrier scattering is at odds with the Abrikosov-Gorkov model due to strong spin-orbit coupling. This is consistent with our band structure calculations which reveal a large spin-orbit coupling gap of εso = 0.21 eV. The band structure is also characterized by helical-like spin textures which are mainly induced by strong spin-orbit coupling and the inversion symmetry breaking in the heterostructure system.

Abstract
Laryngeal carcinoma is a common malignant tumor in the head and neck, and the squamous cell carcinoma of the larynx is the most prevelance. In view of the importance of laryngeal function and its survival, the choice of the best therapeutic regimen of laryngeal carcinoma must consider the potential survival rate and the change of postoperative function. The margin of laryngeal carcinoma is an important index of preoperative imaging evaluation of laryngeal carcinoma. The accurate determination of the cutting edge determines the operation mode, the success rate, the survival rate and prognosis of the patients with laryngeal carcinoma.In recent years, the method of preoperative evaluation of laryngeal tumors is diverse, including molecular, imaging and endoscopy, among which preoperative imaging is the most common method. The purpose of this study was to summarize the evaluation of different imaging techniques in the assessment of local invasion and recurrence of submucosal tumors in laryngeal carcinoma.

Abstract
The objective of this study was to investigate the prognostic value of peripheral blood monocytes in esophageal squamous cell carcinoma (ESCC) patients who underwent esophagectomy. Records from 218 consecutive patients with histologically diagnosed ESCC who underwent esophagectomy at Qilu Hospital of Shandong University from January 2007 to December 2008 were retrospectively reviewed. The median disease-free survival (DFS) of this cohort was 29.0 months, and the 5-year DFS rate was 34.4%. The median overall survival (OS) was 35.0 months, and the 5-year OS rate was 37.6%. The cut-off value of 0.42 × 109 /L for the absolute monocyte count (AMC) was chosen as optimal to discriminate between survival and death by applying receiver operating curve analysis. There were 131 patients (60.1%) who had high AMC (≥0.42 × 109 /L) preoperatively. We found that AMC was significantly associated with gender, tumor location, and platelet count. Kaplan-Meier survival analysis of patients with high preoperative AMC had a significant worse prognosis for DFS (high vs. low: 27.5% vs. 39.0%, P = 0.015) and OS (high vs. low: 31.1% vs. 44.8%, P = 0.009) than those with low preoperative AMC. In a multivariate analysis, preoperative AMC was an independent prognostic factor for DFS (P = 0.025, hazard ratio [HR]: 1.469, 95% confidence interval [CI]: 1.050-2.054) and OS (P = 0.015, HR: 1.547, 95% CI: 1.088-2.200). In addition, among 140 patients without both preoperative and postoperative therapy, significantly worse OS (P = 0.012) and marginally reduced DFS (P = 0.079) were found in the high AMC cohort versus the low AMC cohort. A higher preoperative absolute peripheral monocyte count can be considered as a useful prognostic marker of ESCC patients who underwent esophagectomy.

Abstract
Aged beef cows (≥ 8 yr of age) produce calves with lower birth and weaning weights. In mammals, aging is associated with reduced hepatic expression of glutamine synthetase (GS) and alanine transaminase (ALT), thus impaired hepatic Gln-Glu cycle function. To determine if the relative protein content of GS, ALT, aspartate transaminase (AST), glutamate transporters (EAAC1, GLT-1), and their regulating protein (GTRAP3-18) differed in biopsied liver tissue of (a) aged vs. young (3 to 4 yr old) nonlactating, nongestating Angus cows (Exp. 1 and 2) and (b) aged mixed-breed cows with and without COMPUDOSE (17β-estradiol) ear implants (Exp. 3), Western blot analyses were performed. In Exp. 1, 12 young (3.62 ± 0.01 yr) and 13 aged (10.08 ± 0.42 yr) cows grazed the same mixed forage for 42 d (August-October). In Exp. 2, 12 young (3.36 ± 0.01 yr) and 12 aged (10.38 ± 0.47 yr) cows were individually fed (1.03% of BW) a corn-silage-based diet to maintain BW for 20 d. For both Exp. 1 and 2, the effect of cow age was assessed by ANOVA using the MIXED procedure of SAS. Cow BW did not change ( ≥ 0.17). Hepatic ALT (78% and 61%) and GS (52% and 71%) protein content (Exp. 1 and 2, respectively) was decreased ( ≤ 0.01), whereas GTRAP3-18 (an inhibitor of EAAC1 activity) increased ( ≤ 0.01; 170% and 136%) and AST, GLT-1, and EAAC1 contents did not differ ( ≥ 0.17) in aged vs. young cows. In Exp. 2, free concentrations (nmol/g) of Glu, Ala, Gln, Arg, and Orn in liver homogenates were determined. Aged cows tended to have less ( = 0.10) free Gln (15.0%) than young cows, whereas other AA concentrations did not differ ( 0.26). In Exp. 3, 14 aged (> 10 yr) cows were randomly allotted ( = 7) to sham or COMPUDOSE (25.7 mg of 17β-estradiol) implant treatment (TRT), and had ad libitum access to alfalfa hay for 28 d. Blood and liver biopsies were collected 14 and 28 d after implant treatment. Treatment, time after implant (DAY), and TRT × DAY effects were assessed by ANOVA using the MIXED procedure of SAS. Cow BW was not affected ( ≥ 0.96). Implant increased ( ≤ 0.02) total plasma estradiol by 220% (5.07 vs. 1.58 pg/mL) and GS protein by 300%, whereas the relative content of other proteins was not altered ( ≥ 0.16). We conclude that hepatic expression of ALT and GS are reduced in aged vs. young cows, and administration of 17β-estradiol to aged cows increases plasma estradiol and hepatic GS, but not that of other proteins that support hepatic Glu metabolism.
