Abstract
167 Background: We have previously shown that consolidation pembrolizumab after chemoradiation is safe in a 93 patient-clinical trial of unresectable stage III NSCLC patients (Durm, ASCO 2016). However 15 patients (16%) developed grade ≥2 pneumonitis. There is limited data on risk factors for developing pneumonitis in this population. We conducted a retrospective review of these patients to identify potential clinical, biologic, radiographic and radiation treatment related risk factors for developing pneumonitis. Methods: We evaluated ECOG PS, age, gender, smoking status, stage, histology, chemo regimen, consolidation chemotherapy, TILs, PDL-1 status, PFTs, PET SUVs, grade of pre-existing ILD, COPD and Radiation dosimetry plans. Logistic regression and fisher’s-exact test were used for the odds ratio and p-values. Results: See Table. [1] [1] Age, histology, stage, chemo, PFTs, SUVs and PDL1 were not significant [2] n = sample size p = pneumonitis [3] Moderate/severe COPD was not seen in any patients with pneumonitis despite 94% of participants being smokers. Conclusions: This preliminary report highlights the utility of a multi-disciplinary approach to develop risk-stratification models for pneumonitis in an at-risk patient population. However larger prospective studies are needed to validate their meaningful use in the clinical setting.[Table: see text]

Abstract
Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS) or sudden death, which typically affects young women. We reported two cases of black Africans patients, aged 56 and 52 years old, who presented to Abidjan Heart Institute for ACS. Coronary angiography showed spontaneous dissection of the right coronary artery in the first case, and dissection of the distal left anterior descending artery in the second. A conservative approach was preferred. Both patients received antiplatelet agents, beta-blockers, angiotensin converting enzyme inhibitors and statins, with a favorable in-hospital course. These cases highlight SCAD as a possible cause of ACS. Implementation of interventional cardiology in Sub-Saharan Africa will help identify this uncommon cause of ACS.

Abstract
The internal structure of nucleons (protons and neutrons) remains one of the greatest outstanding problems in modern nuclear physics. By scattering high-energy electrons off a proton we are able to resolve its fundamental constituents and probe their momenta and positions. Here we investigate the dynamics of quarks and gluons inside nucleons using deeply virtual Compton scattering (DVCS)-a highly virtual photon scatters off the proton, which subsequently radiates a photon. DVCS interferes with the Bethe-Heitler (BH) process, where the photon is emitted by the electron rather than the proton. We report herein the full determination of the BH-DVCS interference by exploiting the distinct energy dependences of the DVCS and BH amplitudes. In the regime where the scattering is expected to occur off a single quark, measurements show an intriguing sensitivity to gluons, the carriers of the strong interaction.

Abstract
The charge and magnetic form factors, F_{C} and F_{M}, respectively, of ^{3}He are extracted in the kinematic range 25 fm^{-2}≤Q^{2}≤61 fm^{-2} from elastic electron scattering by detecting ^{3}He recoil nuclei and scattered electrons in coincidence with the two High Resolution Spectrometers of the Hall A Facility at Jefferson Lab. The measurements find evidence for the existence of a second diffraction minimum for the magnetic form factor at Q^{2}=49.3 fm^{-2} and for the charge form factor at Q^{2}=62.0 fm^{-2}. Both minima are predicted to exist in the Q^{2} range accessible by this Jefferson Lab experiment. The data are in qualitative agreement with theoretical calculations based on realistic interactions and accurate methods to solve the three-body nuclear problem.

Abstract
Pathogenic <em>Escherichia coli</em> (<em>E. coli</em>) is severely threatening the rabbit industry in China, and the concern over antibiotic-resistant bacteria has given rise to an urgent need for antibiotic alternatives. In this study, a member (ZRP1) of the <em>Myoviridae</em> family was isolated from rabbit faeces using a strain of rabbit atypical enteropathogenic <em>E. coli</em> (ZR1) as host. The one-step growth curve indicated that the latent period was around 25 to 30 min and the burst size was 144±31 plaque-forming unit/cell. The rate of phage-resistant mutation was 7×10<sup>–5</sup>±4×10<sup>–5</sup>. When the bacteriophage input at the multiplicity of infection (MOI) was 0.1, 1 or 10, the growth of host <em>E. coli</em> in broth was inhibited for 5 h. A single intravenous injection of ZRP1 at MOI 0.1, 1 or 10 significantly prolonged the survival time of rabbits which simultaneously received a lethal dose of ZR1.

Abstract
In this research, we report the regioselective synthesis of methylene-bridged naphthalene oligomers from 2,6-dialkoxyl naphthanene and paraformaldehyde by using p-TsOH as the catalyst and CH2Cl2 as the solvent. The structures were characterized by NMR spectroscopy and X-ray crystallography. Their host-guest chemistry with organic cations was studied, and optimal naphthalene numbers in the oligomers were revealed for different guests. In addition, the reason for the unsuccessful synthesis of methylene-bridged naphthalene macrocycles was discussed.

Abstract
Whether enteral nutrition (EN) is superior to parenteral nutrition (PN) in critically ill patients with severe acute pancreatitis remains unknown. The objective of this meta-analysis was to assess the effects of EN versus PN on clinical outcomes in a subgroup of pancreatitis patients. Relevant randomized controlled trials (RCTs) were searched in Scopus, PubMed and Web of Science from inception to August 2016. Ultimately, five RCTs including 348 patients were enrolled in this analysis. Compared with PN, EN was associated with a significant reduction in overall mortality (risk ratio (RR)=0.36, 95% confidence interval (CI) 0.20-0.65, P=0.001) and the rate of multiple organ failure (RR=0.39, 95% CI 0.21-0.73, P=0.003). EN should be recommended as the preferred route of nutrition for critically ill patients with severe acute pancreatitis.

Abstract
OBJECTIVE This study aimed to analyze the hereditary spastic paraplegia (HSP)/spastic paraplegia 3A (SPG3A) genomic structure as well as the polymorphisms in SPG3G genomic structure by comparing with the normal subjects. METHODS A total of 66 sporadic cases with HSP were collected from April 2014 to September 2016. Genomic DNA extraction was performed, and all coding exons and junction region in the SPG3A gene were sequenced. Genetic mutations were identified and DNA sequence alignment was performed against 80 normal subjects without blood relationship. The polymorphism in SPG3A gene was analyzed. RESULTS The coding sequence of the SPG3A gene consisted of 14 exons and two polymorphisms were detected at exons 2 and 3 compared with the normal subjects; one polymorphism was detected at exons 3, 4 and 6, respectively. CONCLUSION The two coding exons in the SPG3A gene in normal subjects were polymorphic and highly conservative. The intron consisted of 3 polymorphic coding sequences. Understanding the polymorphism and genetic mutations in the SPG3A gene will contribute to the diagnosis and treatment of HSP.

Abstract
OBJECTIVE The present study was planned to explore the role of 8-isomeric-prostaglandinF2α (8-iso-PGF2α) levels at the multiple sites of cerebrospinal fluid in children with intracranial hemorrhage. PATIENTS AND METHODS 90 children with intracranial hemorrhage were admitted to Surgery Intensive Care Unit (SICU) of our hospital from January to December 2013 and were selected as study subjects. They were divided into group A (n=30), group B (n=30) and group C (n=30). The group A was given conventional treatment, the group B was treated with minimally invasive puncture and the group C was treated with cerebrospinal fluid decompression. After 1 d, 2 d, 3 d, and 7 d of hospitalization, enzyme-linked immunosorbent assay (ELISA) was used to detect the 8-iso-PGF2α levels in peripheral blood of children in all groups. On the day of admission and 10 d after treatment, 3 groups of children were implemented with brain nuclear magnetic resonance spectroscopy for metabolite analyses. RESULTS On the day of admission there were no significant differences in the 8-iso-PGF2α levels among group A, B and C. Further, after 1 d, 3 d, 7 d of hospital stay, the 8-iso-PGF2α levels in peripheral blood showed a gradual downward trend, and decline range of the group C was greater than that of group A and B (p < 0.05). After 10 days of treatment, there were significant differences in the bilateral temporal lobe and hippocampal NAA/Creatinine (Cr), Cho/Cr, mI/Cr and NAA/mI among group A, B, and C. The survival rate of group C was higher than that of group A and B (p < 0.05). On the other hand, the prevalence of sequelae was significantly lower than that of group A and B (p < 0.05). The amount of blood loss in children with intracranial hemorrhage was positively correlated with the levels of 8-iso-PGF2α in peripheral blood (r = 0.546, p < 0.05) as observed by Spearman correlation analysis. CONCLUSIONS 8-iso-PGF2α plays an important role in the pathogenesis of intracranial hemorrhage, and could be utilized as a biomarker of oxidative stress in children with intracranial hemorrhage. Further, cerebrospinal fluid decompression is a better method of treatment for intracranial hemorrhage.

Abstract
Numerous studies confirmed that aberrant miRNAs expression contributes to multiple myeloma (MM) development and progression. However, the roles of specific miRNAs in MM remain to be investigated. In present study, we demonstrated that miR-410 expression was increased in MM newly diagnosed and relapsed tissues and cell lines. Clinical analysis revealed that miR-410 was positively correlated with advanced ISS stage. Moreover, high miR-410 expression in MM patients showed an obvious shorter overall survival and progression-free survival. Gain- and loss-of function experiments indicated that miR-410 promoted cell proliferation, cell cycle progression and apoptosis inhibition both in vitro and in vivo. Moreover, KLF10 was identified as a direct downstream target of miR-410 in MM cells, and mediated the functional influence of miR-410 in MM, resulting in PTEN/AKT activation. In clinical samples of MM, miR-410 inversely correlated with KLF10. Alteration of KLF10 expression or AKT inhibitor at least partially abolished the biological effects of miR-410 on MM cells. Furthermore, downregulated expression of lncRNA OIP5-AS1 was inversely correlated with miR-410 expression in MM tissues. LncRNA OIP5-AS1 could modulate the miR-410 expression and regulate its target KLF10/PTEN/AKT-mediated cellular behaviors. Taken together, this research supports the first evidence that lncRNA OIP5-AS1 loss-induced miR-410 accumulation facilitates cell proliferation, cycle progression and apoptosis inhibition by targeting KLF10 via activating PTEN/PI3K/AKT pathway in MM.

Abstract
There is no consensus as to whether drainage tube should be used and how long it should remain in use after primary total knee arthroplasty (TKA). As fast-track (FT) program has been implemented in TKA, whether drainage tube could be removed early, and the ideal timing for removal after FT primary TKA has been a new topic. The purpose of this prospective cohort study was to evaluate the safety and feasibility of early removal of drainage tube when FT program was implemented in primary TKA. A total of 101 patients undergoing FT primary TKA were prospectively allocated into three groups. Patients in group A (31 patients) indwelled wound drainage tube for 6 hours after surgery while group B (34 patients) for 12 hours and group C (36 patients) for 18 hours. The knee circumference, resting and moving visual analogue score (VAS), hemoglobin (Hb), hematocrit, white blood count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), interleukin-6 (IL-6), the volume of blood loss and drainage, and postoperative length of stay (LOS) among three groups were recorded and compared. There was no statistically significant difference in the volume of total and hidden blood loss among three groups (p > 0.05), but as the time of drainage prolonged, total volume of drainage and dominant blood loss increased gradually (p < 0.01). The knee circumference, the mean of resting and moving VAS, Hb, WBC, ESR, CRP, and IL-6 of three groups were similar preoperatively and on postoperative day 1 and 3 (p > 0.05), the decrease of Hb in the perioperative period and postoperative LOS as well. Early removal of wound drainage tube could drain the hematocele and reduce the risk of infection, and it doesn't increase the sense of pain, inflammatory reaction, limb swelling, and total blood loss. It's safe and feasible to remove the drainage tube within 6 to 12 hours after FT primary TKA.

MATERIALS AND METHODS Confined compression tests characterized mechanical TMJ disc properties, which were incorporated into a biphasic finite element model (FEM). The FEM was established to investigate load carriage within the extracellular matrix (ECM) and the ploughing mechanism during tractional force formation by simulating previous in vitro plough experiments. RESULTS Biphasic mechanical properties were determined in five TMJ disc regions (average±standard deviation for aggregate modulus: 0.077±0.040 MPa; hydraulic permeability: 0.88±0.37×10-3 mm4 /Ns). FE simulation results demonstrated that interstitial fluid pressurization is a dominant loading support mechanism in the TMJ disc. Increased contact load and duration led to increased solid ECM strain and stress within, and increased ploughing force on the surface of the disc. CONCLUSION Sustained mechanical loading may play a role in load carriage within the ECM and ploughing force formation during stress-field translation at the condyle-disc interface. This study further elucidated the mechanism of ploughing on tractional force formation and provided a baseline for future analysis of TMJ mechanics, cartilage fatigue and early TMJ degeneration.

Abstract
Temporomandibular disorder (TMD) incidences are believed to be related to parafunctional behaviours like teeth clenching. This pilot study aimed to (i) develop an automated clench-detection algorithm, and (ii) apply the algorithm to test for differences in nocturnal clenching in women with and without TMD. Subjects gave informed consent to participate. Adult women were categorised using Diagnostic Criteria for TMD according to presence/absence (+/-) of both TM joint disc placement (DD) and chronic pain (P) into two groups (+DD+P, -DD-P) with 12 subjects each. Surface temporalis electromyography was recorded during oral tasks performed by subjects at two laboratory sessions. The data were used to characterise muscle activity per N of bite force (μV/N) for each subject, develop the clench-detection algorithm and test its accuracy. Ambulatory surface temporalis electromyography was self-recorded by each subject over three nights and analysed using the algorithm and bite force (N) versus muscle activity μV/N calibrations. Bonferroni-adjusted homoscedastic t-tests assessed for significant between-group differences in clenching (P < 0·05). Sensitivity, specificity and accuracy of algorithm-detected laboratory clenches were all ≥96%. During self-recordings 95% of clenches had durations of <4 s and peak forces of <10 N in both groups. Mean clench durations were significantly longer (P = 0·042) in +DD+P (1·9 ± 0·8 s) than -DD-P subjects (1·4 ± 0·4 s). Mean temporalis duty factors (%clench time/total recording time) were significantly larger (P = 0·041) in +DD+P (0·47 ± 0·34%) than -DD-P (0·26 ±0·22%) subjects. Nocturnal temporalis muscle activities detected by a validated algorithm were longer per clench and recording time in +DD+P compared to -DD-P women.

Abstract
BACKGROUND Acute renal injury (AKI) is a common renal complication after cardiac surgery. The aim of this study was to determine the effect of perioperative statin therapy (PST) on postoperative renal outcome in patients undergoing cardiac procedures. METHODS We searched for the reports that evaluating the effect of PST on renal outcomes after cardiac surgery between March 1983 and June 2016 in the electronic database Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE/PubMed, and EMBASE/OVID. RESULTS Nine randomized controlled trials (RCTs) enrolling 2832 patients, with 1419 in the PST group and 1413 in the control group, were included in this meta-analysis. Our results suggested that PST increased the incidence of postoperative renal complication (relative risk [RR] 1.18, 95% confidence interval [CI] 1.01-1.36, P = .03) with low heterogeneity (I = 30%, P = .18). Six studies with 3116 patients detected no significant difference in severe renal complication between PST and control groups (RR 1.23, 95%CI 0.84-1.79, P = .28). Postoperative serum creatinine (sCr) at 48 hours was shown to be higher in the PST group (mean difference [MD] 0.03, 95% CI 0.03-0.03; P < .01). The length of hospital stay was decreased slightly by 0.59 day in the PST group (95% CI -0.85 to -0.33; P < .01). CONCLUSIONS Perioperative statin therapy seems to jeopardize short-term renal outcome in patients undergoing cardiac surgery, but the occurrence of severe renal complication was not affected.

Abstract
BACKGROUND Bone marrow micro-environment changes during hematopoietic stem cell transplantation (HSCT) with subsequent alteration of genes expression. Quantitative polymerase chain reaction (q-PCR) is a reliable and reproducible technique for the analysis of gene expression. To obtain more accurate results, it is essential to find a reference during HSCT. However, which gene is suitable during HSCT remains unclear. This study aimed to identify suitable reference genes for mRNA studies in bone marrow after HSCT. METHODS C57BL/6 mice were treated with either total body irradiation (group T) or busulfan/cyclophosphamide (BU/CY) (group B) followed by infusion of bone marrow cells. Normal mice without treatments were served as a control. All samples (group T + group B + control) were defined as group G. On days 7, 14, and 21 after transplantation, transcription levels of 7 candidate genes, ACTB, B2M, GAPDH, HMBS, HPRT, SDHA, and YWHAZ, in bone marrow cells were measured by use of real-time quantitative PCR. The expression stability of these 7 candidate reference genes were analyzed by 2 statistical software programs, GeNorm and NormFinder. RESULTS Our results showed that ACTB displayed the highest expression in group G, with lowest expression of PSDHA in group T and HPRT in groups B and G. Analysis of expression stability by use of GeNorm or NormFinder demonstrated that expression of B2M in bone marrow were much more stable during HSCT, compared with other candidate genes including commonly used reference genes GAPDH and ACTB. CONCLUSIONS ACTB could be used as a suitable reference gene for mRNA studies in bone marrow after HSCT.
