Abstract
BACKGROUND Autophagy is a lysosomal degradation pathway that is essential for cell survival, differentiation, and homeostasis. This study aimed to investigate the contribution of autophagy to the pathogenesis of CRS with nasal polyps (CRSwNP). METHODS The expression of autophagic proteins [microtubule-associated protein 1 light chain 3B (LC3B)-II, autophagy-related proteins (Atg), and Beclin 1], substrate proteins (p62 and ubiquitinated proteins), and apoptotic signaling molecules [cysteine-aspartic protease-3 and cysteine-aspartic protease-8, and poly-ADP-ribose polymerase] in the sinonasal mucosa and nasal epithelial cells (NECs) was detected by immunohistochemistry and Western blotting. Autophagic vacuoles were observed with transmission electron microscopy. BEAS-2B cells and NECs were treated with rapamycin, bafilomycin A1, or various cytokines. In some experiments, cultured NECs were transfected with small interfering RNA targeting p62 (sip62) or Atg5 (siAtg5). Cultured cells were analyzed with Western blotting and flow cytometry. RESULTS Although autophagic protein expression and autophagic vacuole formation were increased in both eosinophilic and noneosinophilic CRSwNP, particularly in NECs, there was also an up-regulation of substrate proteins and apoptotic signaling molecules. IFN-γ, but not IL-4, IL-13, or IL-17A, simultaneously enhanced LC3B-II and p62 levels as well as cell apoptosis in BEAS-2B cells and/or normal NECs. Bafilomycin A1 up-regulated the levels of LC3B-II and p62 in polyp NECs and IFN-γ-treated normal NECs. IFN-γ-induced apoptosis of normal NECs was exaggerated by bafilomycin A1 and siAtg5. Sip62 suppressed apoptosis of polyp NECs and IFN-γ-treated NECs. IFN-γ protein levels were increased in both eosinophilic and noneosinophilic CRSwNP. CONCLUSIONS IFN-γ induces activated but insufficient autophagy and thus contributes to a degree to p62-dependent apoptosis of NECs in CRSwNP.

Abstract
OBJECTIVE To investigated the influence of hyperthermal perfusion chemotherapy combined with immunologic therapy on the immunologic function and levels of circulating tumor cells of the advanced colorectal cancer patients with liver metastasis. PATIENTS AND METHODS We enrolled 98 advanced colorectal cancer patients with liver metastasis that were admitted to this hospital for treatment and were randomly divided into two groups, the observation group (n = 49) and the control group (n = 49). We administered systemic vein chemotherapy for patients in the control group, and hyperthermal perfusion chemotherapy for the patients in the observation group in order to compare the subgroup levels of T lymphocytes, NK cells and immunoglobulin (IgG, IgA, and IgM) in the immune system of patients in both groups. We also assayed the circulating tumor cells (CTC) in the peripheral blood of patients in both groups using the cell search method, and compared the efficacy using response evaluation criteria in solid tumors and the survival rates of patients in both groups using the Kaplan-Meier method. RESULTS After two treatment courses, the levels of CD3+, CD4+ and CD4+/CD8+ of the patients in the observation group were significantly higher than those of the control group, but the levels of CD8+ of patients in the observation group was lower than that in the control group (p< 0.05). The levels of immunoglobulins (IgG, IgA, and IgM) in the observation group were higher than the control group (p < 0.05). The levels of NK cell cells were significantly lower than the control group (p < 0.05). The objective response rate, as well as the disease control rate of the observation group, were remarkably higher than those of the control group (p < 0.05). Compared to the control group, the observation group enjoyed a prolonged survival time, higher survival rate and significantly lower positive rate of CTC (p < 0.05). CONCLUSIONS Better efficacy and tolerance, fewer toxic and side effects, improvement in the immunologic functions of patients for the indirect anti-tumor effect, a significant decrease in CTC of patients, and a higher long-term survival rate have been achieved in the treatment with hyperthermal perfusion chemotherapy combined with immunologic therapy for the advanced colorectal cancer patients with liver metastasis. Thus, it can serve as the preferable drug for the treatment of advanced colorectal cancer with liver metastasis.

Abstract
Objective: To investigate the clinical features and viral load of persons infected with HCV and the risk factors for severe outcomes. Methods: Medical testing and questionnaire survey were conducted on 465 cases who were infected with HCV, 20-30 years back. HCV RNA, alanine transaminase (ALT), aspartate transaminase (AST), albumin, globulin and bilirubin were tested for these subjects. Factors as demography, tobacco and alcohol consumption, SNP of rs7453920 and rs2856718 on HLA-DQ gene of subjects with HCV RNA, were analyzed by multiple logistic regression method to explore the risk factors for severe outcomes among the patients. Result: Totally, 465 subjects had symptoms as hypodynamic (15.70%, 73/465), digestive system (17.63%, 82/465), and arthrodynia (10.32%, 48/465). HCV RNA was positive in 68.60% (319/465) of the subjects with median viral load as 76.01×10(4) copies/ml (min-max: 592 copies/ml -1.08×10(10) copies/ml). Totally, 11.83% (55/465) of the cases appeared having liver inflammation by routine ultrasound exams. ALT and AST was seen higher than 80 (IU/L) in 12.70% (59/465) and 11.18% (52/465) of the subjects, separately. Factors as being male (OR =2.298, 95%CI: 1.247-4.238), GA genotype compared with AA type in rs2856718 (OR=1.716, 95%CI: 1.070-2.752), alcohol intake ≥7 times per-week (OR=2.966, 95% CI: 0.979-8.988) etc., were independently related to HCV RNA sustained positivity. Factors as: being male (OR=1.694, 95%CI: 0.975-2.942), in 50-59 years age group (OR=2.414, 95%CI: 1.156-5.042), having other liver diseases (OR=2.592, 95% CI: 1.105-6.079) and carrying positive HCV RNA (OR=3.479, 95% CI: 1.648-7.343) etc. were independent risk factors for abnormal liver function. Conclusion: High rates of carrying sustained positive HCV RNA and abnormal liver function appeared in subjects who got the HCV infection 20-30 years ago. Factors as being male, in old age, being frequent alcohol taker, GA genotype in rs2856718 and with other liver diseases etc. were related to higher risk for developing severe outcomes.

Abstract
Systemic anaplastic large cell lymphomas (sALCLs) comprise a heterogeneous group of relatively rare T-cell non-Hodgkin lymphomas that are characterized by CD30 expression. Anaplastic lymphoma kinase (ALK)-positive ALCL is a type of sALCL that commonly involves lymph nodes and extranodal sites. Skin involvement usually presents as tumours, nodules and ulcers. We describe an unusual case of ALK-positive ALCL in an 11-year-old Chinese boy, who initially presented with skin eruption with rapid progression and poor prognosis. This case emphasizes the value of clinical factors to predict the prognosis of ALK-positive sALCL, and we recommend close collaboration between dermatologists, pathologists and haematologists/oncologists to assure the correct diagnosis and treatment.

Abstract
L-Tryptophan (Trp) and some of its metabolites regulate the circadian rhythm in mammals. We aimed to investigate the effects of short-term supplementation of Trp in isocaloric meals on growth performance using the parameters of multiple blood biomarkers and free amino acids in growing pigs. A total of 32 Landrace × Yorkshire barrows with a mean body weight of 8.64 (±1.13) kg were randomly assigned to four groups and then fed with various concentrations of Trp diets daily. Our results showed that sequential supplementation of different concentrations of Trp in isocaloric meals decreased the feed:gain (F:G) ratio (P = 0.079) and plasma urea and albumin (P = 0.019), whereas the level of total protein did not. Among the essential and conditionally essential amino acids, the concentrations of histidine, isoleucine, proline, threonine, arginine, and valine in the plasma decreased (P < 0.05), whereas the concentrations of Trp, glycine, serine, and methionine increased (P < 0.01). In addition, concentrations of branched chain amino acids also significantly decreased (P = 0.004), while the rate of conversion of Trp to branched chain amino acids increased (P < 0.001). Taken together, we show that administration of a high concentration of Trp in breakfast with decreasing concentrations of Trp in lunch and dinner positively affected feed utilization and improved feed efficiency, at least in part, through the optimization of amino acid interconversions and nitrogen utilization.

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.

Abstract
AIMS To analyse whether some indoleacetic acid (IAA)-secreting plant growth-promoting bacteria can alleviate cadmium (Cd) stress, the role of an Ochrobactrum sp. MGJ11 from rhizosphere of soybean in promoting plant growth, and to evaluate the counteracting Cd effects on soybean. METHODS AND RESULTS Ochrobactrum sp. MGJ11 produced 121·2 mg l-1 of IAA. MGJ11 increased soybean root length, shoot length and biomass by 30·1, 30·8 and 13·4% respectively. In liquid medium, no IAA production was detected in Cd concentration of 100 mg l-1 . In soil with 20-80 mg kg-1 Cd, MGJ11 promoted soybean root elongation (29·4-161·4%) and increased the shoot length (up to 52·7%) and biomass (up to 87·2%). After growing for 38 days, Cd concentrations in the roots of inoculated soybean were lower than in those of noninoculated plants. Only a little Cd (2·6-16·9 μg g-1 ) was translocated from the root to shoot. CONCLUSIONS Ochrobactrum sp. MGJ11 secretes IAA and shows tolerance against Cd. MGJ11 inoculation improves the root length, shoot length and biomass of soybean in both vermiculite and Cd vermiculite, and decreases Cd concentration of soybean root. The characteristics of MGJ11 suggest that it could be used for promoting soybean growth and lowering bioavailability of soil Cd for soybean root. SIGNIFICANCE AND IMPACT OF THE STUDY In this study, we isolated a plant growth-promoting Ochrobactrum with the activity of mitigating Cd toxicity to plant roots. The Ochrobactrum can be considered as a potential bioaugmentation agent that promotes plant growth, especially in some agricultural systems, or that helps in the phytoremediation of Cd-contaminated soil.

Abstract
The potential of Fourier transform infrared (FT-IR) transmission spectroscopy for determination of lead chrome green in green tea was investigated based on chemometric methods. Firstly, the qualitative analysis of lead chrome green in tea was performed based on partial least squares discriminant analysis (PLS-DA), and the correct rate of classification was 100%. And then, a hybrid method of interval partial least squares (iPLS) regression and successive projections algorithm (SPA) was proposed to select characteristic wavenumbers for the quantitative analysis of lead chrome green in green tea, and 19 wavenumbers were obtained finally. Among these wavenumbers, 1384 (C = C), 1456, 1438, 1419(C = N), and 1506 (CNH) cm-1 were the characteristic wavenumbers of lead chrome green. Then, these 19 wavenumbers were used to build determination models. The best model was achieved by least squares support vector machine (LS-SVM)algorithm with high coefficient of determination and low root-mean square error of prediction set (R2p = 0.864 and RMSEP = 0.291). All these results indicated the feasibility of IR spectra for detecting lead chrome green in green tea.

Abstract
Empirical evidence has suggested that social support from family can help patients take their medicines correctly. This study aims to evaluate the role of a family member-based supervision package in the management of hypertension using a cluster randomized trial in rural China. We recruited patients with hypertension from four villages in Yangzhong and randomly allocated them to the control group (n=288) and the intervention group (n=266). A family member-based supervision package was applied to the intervention group, while the usual service was applied to the controls. Patients were followed for 12 months and completed face-to-face interviews at the end of 6 and 12 months. The primary outcomes were patients' medication adherence and frequency of blood pressure measurement. Secondary outcomes included changes in blood pressure, altered risk behaviours and occurrence of hypertension-related complications. To control for the effects of cluster randomization, multilevel mixed-effects regression models were used to compare group changes. We observed that the intervention improved patients' blood pressure measurement frequency (OR: 9.00, 95% CI: 4.52-17.91) and adherence to antihypertensive treatment (OR: 1.74, 95% CI: 0.91-3.32). Its effect on the blood pressure control rate was significant at the mid-term investigation (OR: 0.67, 95% CI: 0.40-0.93), but the long-term effect was not significant (OR: 0.89, 95% CI: 0.64-1.26). After 6 months of intervention, either systolic or diastolic blood pressure was significantly decreased in the intervention group. However, this difference was not significant at the final investigation. Findings from this study revealed that the family member-based supervised therapy may have positive effects on patients' adherence to blood monitoring and hypertensive medications.

Abstract
OBJECTIVE Using data from a cohort of World Trade Center (WTC) rescue and recovery workers with asthma, we assessed whether meeting criteria for post-traumatic stress disorder (PTSD), sub-threshold PTSD, and for specific PTSD symptom dimensions are associated with increased asthma morbidity. METHODS Participants underwent a Structured Clinical Interview for Diagnostic and Statistical Manual to assess the presence of PTSD following DSM-IV criteria during in-person interviews between December 2013 and April 2015. We defined sub-threshold PTSD as meeting criteria for two of three symptom dimensions: re-experiencing, avoidance, or hyper-arousal. Asthma control, acute asthma-related healthcare utilization, and asthma-related quality of life data were collected using validated scales. Unadjusted and multiple regression analyses were performed to assess the relationship between sub-threshold PTSD and PTSD symptom domains with asthma morbidity measures. RESULTS Of the 181 WTC workers with asthma recruited into the study, 28% had PTSD and 25% had sub-threshold PTSD. Patients with PTSD showed worse asthma control, higher rates of inpatient healthcare utilization, and poorer asthma quality of life than those with sub-threshold or no PTSD. After adjusting for potential confounders, among patients not meeting the criteria for full PTSD, those presenting symptoms of re-experiencing exhibited poorer quality of life (p = 0.003). Avoidance was associated with increased acute healthcare use (p = 0.05). Sub-threshold PTSD was not associated with asthma morbidity (p > 0.05 for all comparisons). CONCLUSIONS There may be benefit in assessing asthma control in patients with sub-threshold PTSD symptoms as well as those with full PTSD to more effectively identify ongoing asthma symptoms and target management strategies.

Abstract
BACKGROUND China may have the largest number of Budd-Chiari syndrome (BCS) cases in the world (at least 1914 original papers were published, and at least 20 191 BCS patients were reported). Considering the discrepancy in the clinical profiles and preferred treatment selection of primary BCS between the West and China, understanding its aetiology in these two different regions is very important. AIM To review the data from large cohort studies and meta-analyses to illustrate the epidemiology of risk factors for BCS in the West and China. METHODS Relevant papers were identified by major English- and Chinese-language databases, conference abstracts, and by manual search. RESULTS Risk factors reviewed include myeloproliferative neoplasms (MPNs) and their related gene mutations, anti-phospholipid syndrome, paroxysmal nocturnal haemoglobinuria (PNH), hyperhomocysteinaemia and 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T mutation, factor V Leiden (FVL) and prothrombin G20210A mutations, inherited anti-thrombin, protein C and protein S deficiencies, pregnancy and puerperium, poverty, and family history. CONCLUSIONS We examined the differences in the aetiological distribution of BCS between the West and China. Several recommendations should be considered in Chinese BCS patients: (i) screening for hyperhomocysteinaemia and MTHFR mutation should be regularly performed; (ii) screening for MPNs, PNH, and anti-phospholipid syndrome should be selectively performed; (iii) inherited anti-thrombin, protein C, and protein S deficiencies should be actively explored; (iv) screening for FVL and prothrombin G20210A mutations may be unnecessary; and (v) the clinical significance of pregnancy and puerperium, poverty with bacterial infections and unsanitary environments, and family history as possible risk factors should never be neglected.

Abstract
Objective: To investigate the value of low-dose multi-slice CT (MSCT) chest scan in the diagnosis of coal workers' pneumoconiosis. Methods: A total of 90 patients with a confirmed diagnosis of coal workers' pneumoconiosis were enrolled, and under the conditions of fixed tube voltage, pitch, and slice thickness, they underwent CT scan with a normal dose (150 mA) and a low dose (30-50 mA). The quality of images obtained from two scans was compared, and the imaging findings, opacity profusion, stage, and radiation doses were also compared. Results: Compared with the normal-dose scan, low-dose scan increased the image noise, and the images obtained from scans with doses of 30, 40, and 50 mA did not show significant reductions in signal-to-noise ratio or contrast-to-noise ratio (P>0.05). There was no significant difference in the percentage of image quality between low-dose and normal-dose scans (P>0.05). There were no significant differences in the percentage of various imaging findings, opacity profusion, or percentage of different stages between low-dose (30, 40, and 50 mA) and normal-dose (150 mA) scans (P>0.05). Conclusion: There are no significant differences between low-dose MSCT chest scan and normal-dose CT in image quality, imaging findings of coal workers' pneumoconiosis, opacity profusion, and stage. Meanwhile, low-dose MSCT chest scan greatly reduces the radiation dose and can be used to assist the diagnosis and follow-up reexamination of coal workers' pneumoconiosis and cover the shortage of high-kilovoltage chest X-ray.

Abstract
Anyons are exotic quasiparticles obeying fractional statistics, whose behavior can be emulated in artificially designed spin systems. Here we present an experimental emulation of creating anyonic excitations in a superconducting circuit that consists of four qubits, achieved by dynamically generating the ground and excited states of the toric code model, i.e., four-qubit Greenberger-Horne-Zeilinger states. The anyonic braiding is implemented via single-qubit rotations: a phase shift of π related to braiding, the hallmark of Abelian 1/2 anyons, has been observed through a Ramsey-type interference measurement.

Abstract
OBJECTIVE To preliminarily explore the application value of two-dimensional image technology and three-dimensional visualization technology in hepatocellular carcinoma(HCC) treated by associating liver partition and portal vein ligation for staged hepatectomy(ALPPS). METHODS Clinical data of nineteen HCC patients treated by ALPPS were retrospectively analyzed in Sun-Yat-Sen Memorial Hospital of Sun Yat-Sen University from August 2013 to May 2015.Preoperative assessment, surgical planning and intraoperative guidance were assisted by traditional two-dimensional imaging technology(group 2D) in 15 cases, and the rest 4 cases were assisted by three-dimensional visualization technology(group 3D). RESULTS Three-dimensional visualization technology offered precise, visual, and distinct images, calculated the liver volume precisely, achieved virtual simulation operations, and assisted the formulation of intraoperative decisions.The mean operation time of the first stage were(331.3±61.7)minutes and (261.3±21.4)minutes in group 2D and group 3D, and the mean volume of intraoperative bleedings were (360.7±51.9)ml and (300.0±40.8)ml, respectively.The mean operation time of the second stage were (199.3±41.0)minutes and (170.0±29.4)minutes in group 2D and group 3D, and the mean volume of intraoperative bleedings were (285.3±132.6)ml and (257.5±99.5)ml, respectively.The mean interval time between two stages of operations were (15.3±6.5)d and (13.8±5.1)d in group 2D and group 3D, and the mean hospital stays were (39.3±5.8)d and (31.5±7.5)d, respectively.There were 4 cases and 12 cases who accepted the second stage operation in group 2D and group 3D respectively.There were 7 cases(4 with grade A, 2 with grade B, 1 with grade C) and 2 cases(1 with grade A, 1 with grade B) with post-hepatectomy liver failure and 9 cases(4 with grade Ⅰ, 2 with grade Ⅱ, 1 with grade Ⅲ, 2 with grade Ⅳ) and 3 cases (1 with grade Ⅰ, 1 with grade Ⅱ, 1 with grade Ⅲ)with postoperative complications in group 2D and group 3D respectively.There were 2 cases and 0 case died after operation in group 2D and group 3D respectively.There were 3 cases and 1 case who were recurrent and 4 cases and 1 case died 6 months after surgery in group 2D and group 3D respectively. CONCLUSION Three-dimensional visualization technology assisted the formulation of preoperative assessments and surgical planning individually and precisely, which displayed potential application value in HCC treated by ALPPS.

Abstract
The presence of whale sharks Rhincodon typus were recorded around Shib Habil, a small, coastal reef off the Red Sea coast of Saudi Arabia, from 2010 to 2015. A total of 267 suitable photographs resulting in the identification of 136 individuals, were documented from 305 encounters. Sharks were divided evenly between the sexes with no evidence of temporal or spatial segregation. All individuals were immature based on size estimates and, for males, juvenile clasper morphology. Scars were reported for 57% of R. typus with 15% showing evidence of propeller trauma. Estimates of population size and patterns of residency were calculated by modelling the lagged identification rate. Multiple models were run simultaneously and compared using the Akaike information criterion. An open population model was found to best represent the data and estimates a daily abundance between 15 and 34 R. typus during the aggregation season, with local residence times ranging from 4 to 44 days. Residence times away from Shib Habil range from 15 to 156 days with a permanent emigration-death rate between 0·07 and 0·58 individuals year(-1) . These results are broadly similar to those from other aggregations of R. typus, although the observed sexual parity and integration found at this site is unique for the species and needs further study.

Abstract
In this study polyhydroxybutyrate (PHB), produced by a methanol-utilizing bacteria, was used to prepare microspheres in the 120-200 μm size range for embolization. A solvent evaporation technique was utilized to obtain microspheres in which methylene chloride, distilled water and polyvinyl alcohol were used as the solvent, precipitation medium and emulsifier, respectively. Dogs were the test animals. Renal angiograms obtained before and after embolization and also the histopathological observations showed the feasibility of using these microspheres as an alternative embolization/chemoembolization agent.

Abstract
Dendritic cells (DCs) are critical in linking the innate and adaptive immune responses, which have been implicated in the pathogenesis of many immune and inflammatory diseases as well as the development of tumours. The role of DCs in the pathophysiology of lung diseases has been widely studied. However, the phenotype, subset and function of DCs in upper airways under physiological or pathological conditions remain largely undefined. Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are two important upper airway diseases with a high worldwide prevalence. Aberrant innate and adaptive immune responses have been considered to play an important role in the pathogenesis of AR and CRS. To this end, understanding the function of DCs in shaping the immune responses in sinonasal mucosa is critical in exploring the pathogenic mechanisms underlying AR and CRS as well as in developing novel therapeutic strategies. This review summarizes the phenotype, subset, function and regulation of DCs in sinonasal mucosa, particularly in the setting of AR and CRS. Furthermore, this review discusses the perspectives for future research and potential clinical utility focusing on DC pathways in the context of AR and CRS.

Abstract
Id1 is a helix-loop-helix transcriptional modulator that increases the aggressiveness of malignant glial neoplasms. Since most glioblastomas (GBMs) show increased phosphatidylinositol-3 kinase (PI-3K) signaling, we sought to determine whether this pathway regulates Id1 expression. Higher basal Id1 expression correlates with dysregulated PI-3K signaling in multiple established GBM cell lines. Further characterization of PI-3K-dependent Id1 regulation reveals that chemical or genetic inhibition of PI-3K signaling reduces Id1 protein but not mRNA expression. Overall, PI-3K signaling appears to enhance Id1 translation with no significant effect on its stability. PI-3K signaling is known to regulate protein translation through mTORC1-dependent phosphorylation of 4E-BP1, which reduces its association with and inhibition of the translation initiation factor eIF4E. Interestingly, while inhibition of PI-3K and AKT lowers 4E-BP1 phosphorylation and expression of Id1 in all cases, inhibition of TORC1 with rapamycin does not consistently have a similar effect suggesting an alternative mechanism for PI-3K-dependent regulation of Id1 translation. We now identify a potential role for the serine-threonine phosphatase PPM1G in translational regulation of Id1 protein expression. PPM1G knockdown by siRNA increase both 4E-BP1 phosphorylation and Id1 expression and PPM1G and 4E-BP1 co-associates in GBM cells. Furthermore, PPM1G is a phosphoprotein and this phosphorylation appears to be regulated by PI-3K activity. Finally, PI-3K inhibition increases PPM1G activity when assessed by an in vitro phosphatase assay. Our findings provide the first evidence that the PI-3K/AKT signaling pathway modulates PPM1G activity resulting in a shift in the balance between hyper- and hypo-phosphorylated 4E-BP1 and translational regulation of Id1 expression.

Abstract
A number of treatment strategies for complex coronary lesions have been utilized in varying clinical settings over the last decade. However, cardiologists still encounter some difficult scenarios such as variant coronary artery origins, severely calcified and highly tortuous lesions. We report four cases in which the stents failed to cross lesions using the conventional percutaneous coronary intervention techniques, but all the target lesions were successfully stented finally using a new combined technique of anchor balloon assisted deep intubation of 5F "child-in-mother" catheter.

Abstract
Considerable epidemiological and laboratory data have suggested that caffeine, a nonselective adenosine receptor antagonist, may protect against the underlying neurodegeneration of parkinson's disease (PD). Although both caffeine and more specific antagonists of the A2A subtype of adenosine receptor (A2AR) have been found to confer protection in animal models of PD, the dependence of caffeine's neuroprotective effects on the A2AR is not known. To definitively determine its A2AR dependence, the effect of caffeine on 1-methyl-4-phenyl-1,2,3,6 tetra-hydropyridine (MPTP) neurotoxicity was compared in wild-type (WT) and A2AR gene global knockout (A2A KO) mice, as well as in central nervous system (CNS) cell type-specific (conditional) A2AR knockout (cKO) mice that lack the receptor either in postnatal forebrain neurons or in astrocytes. In WT and in heterozygous A2AR KO mice caffeine pretreatment (25mg/kgip) significantly attenuated MPTP-induced depletion of striatal dopamine. By contrast in homozygous A2AR global KO mice caffeine had no effect on MPTP toxicity. In forebrain neuron A2AR cKO mice, caffeine lost its locomotor stimulant effect, whereas its neuroprotective effect was mostly preserved. In astrocytic A2AR cKO mice, both caffeine's locomotor stimulant and protective properties were undiminished. Taken together, these results indicate that neuroprotection by caffeine in the MPTP model of PD relies on the A2AR, although the specific cellular localization of these receptors remains to be determined.

Abstract
Abstract
Objectives: The nuclear enzyme PARP-1 plays a central role in sensing DNA damage and facilitating repair. Tumors with BRCA1/2 mutations are highly dependent on PARP-1 as an alternative mechanism for DNA repair, and PARP inhibitors generate synthetic lethality in tumors with BRCA mutations, resulting in cell cycle arrest and apoptosis. Zhou et al. recently synthesized an 18F-labeled PARP-1 inhibitor (18F-FluorThanatrace) for PET, and demonstrated high specific tracer uptake in a xenograft model of breast cancer (Zhou, Bioorg Med Chem, 22:1700, 2014). The current study seeks to quantify the relationship between 18F-FluorThanatrace binding (both in vitro and on PET imaging of human tumor xenografts) and the level of constitutively active PARP-1, using multiple human breast cancer cell lines, including a BRCA1 defective line.
Methods: BRCA1 defective HCC1937, triple negative MDA-MB-231, and luminal A MCF-7 human breast cancer lines were assessed for constitutive PARP-1 activity via a chemiluminescent ELISA assay for PAR and by Western blot. The same cell lines were incubated with 18F-FluorThanatrace over various time increments, and tracer uptake was assayed via a gamma counter. Specificity of tracer binding was verified via co-incubation with competitive inhibitor Olaparib, and specific tracer uptake was calculated as the difference between uptake with and without Olaparib. Specific tracer uptake was compared to levels of constitutive PARP-1 activity in all cell lines. In addition, HCC1937 and MDA-MB-231 xenograft tumor models were imaged via 18F-FluorThanatrace-PET/CT, and PET uptake was correlated with PARP-1 activity.
Results: BRCA1-defective HCC1937 had higher constitutive PARP-1 activity than cell lines with intact BRCA1. In vitro levels of 18F-FluorThanatrace uptake correlated with constitutive PARP-1 activity across cell lines. In addition, 18F-FluorThanatrace measured by PET in xenograft breast cancer tumor models correlated with constitutive PARP-1 activity.
Conclusions: Tumor uptake of 18F-FluorThanatrace, both in vitro and on PET imaging of xenograft tumor models, quantitatively reflects differences in PARP-1 activity across different breast cancer cell lines, including BRCA1 defective. This motivates further studies of 18F-FluorThanatrace as an in vivo measure of PARP-1 activity and possibly as a predictive marker for PARP-1 therapy in patients, including those with BRCA1/2 mutations.

Abstract
New tetraarylazadipyrromethene metal complexes with four coordinate metals (cobalt(ii), nickel(ii), copper(ii) and zinc(ii)) and with three moieties (4-methylphenyl,4-methoxyphenyl and 1-naphthyl) were designed and synthesized targeting applications utilizing two photon absorption. The effects of metals with filled or unfilled d orbitals and substituents with various electron donor properties on the charge transfer mechanism and two photon absorption properties of tetraarylazadipyrromethene compounds were investigated by ultrafast pump-probe spectroscopy and open aperture Z-scan experiments as well as density functional theory (DFT) calculations. Ultrafast transient absorption spectra provide evidence of an efficient photoinduced intramolecular charge transfer between the ligand and metals which is independent of filled or unfilled d orbitals of metals. Although zinc has filled d orbitals, its complexes possess an absorption maximum including a shoulder which is attributed to partial ligand to metal L(π) → M(d*) charge transfer character (LMCT). Due to the charge transfer mechanism, metal complexes of tetraarylazadipyrromethene compounds exhibited two photon absorption properties in the femtosecond regime at 800 nm wavelength. The greatest two photon absorption cross section value was measured as 2690 GM for Zn(L(2))2 and 2374 GM for Co(L(3))2 complexes.

Abstract
We suggest and demonstrate a protocol which suppresses the low-frequency dephasing by qubit motion, i.e., transfer of the logical qubit of information in a system of n≥2 physical qubits. The protocol requires only the nearest-neighbor coupling and is applicable to different qubit structures. Our analysis of its effectiveness against noises with arbitrary correlations, together with experiments using up to three superconducting qubits, shows that for the realistic uncorrelated noises, qubit motion increases the dephasing time of the logical qubit as √n. In general, the protocol provides a diagnostic tool for measurements of the noise correlations.

Abstract
Regulators of the histone H3-trimethyl lysine-4 (H3K4me3) mark are significantly associated with the genetic risk architecture of common neurodevelopmental disease, including schizophrenia and autism. Typical H3K4me3 is primarily localized in the form of sharp peaks, extending in neuronal chromatin on average only across 500-1500 base pairs mostly in close proximity to annotated transcription start sites. Here, through integrative computational analysis of epigenomic and transcriptomic data based on next-generation sequencing, we investigated H3K4me3 landscapes of sorted neuronal and non-neuronal nuclei in human postmortem, non-human primate and mouse prefrontal cortex (PFC), and blood. To explore whether H3K4me3 peak signals could also extend across much broader domains, we examined broadest domain cell-type-specific H3K4me3 peaks in an unbiased manner with an innovative approach on 41+12 ChIP-seq and RNA-seq data sets. In PFC neurons, broadest H3K4me3 distribution ranged from 3.9 to 12 kb, with extremely broad peaks (~10 kb or broader) related to synaptic function and GABAergic signaling (DLX1, ELFN1, GAD1, IGSF9B and LINC00966). Broadest neuronal peaks showed distinct motif signatures and were centrally positioned in prefrontal gene-regulatory Bayesian networks and sensitive to defective neurodevelopment. Approximately 120 of the broadest H3K4me3 peaks in human PFC neurons, including many genes related to glutamatergic and dopaminergic signaling, were fully conserved in chimpanzee, macaque and mouse cortical neurons. Exploration of spread and breadth of lysine methylation markings could provide novel insights into epigenetic mechanism involved in neuropsychiatric disease and neuronal genome evolution.

Abstract
OBJECTIVE To evaluate the informativeness of magnetic resonance venography (MRV) in the diagnosis of different types of inferior vena cava (IVC) obstruction. PATIENTS AND METHODS 56 patients with IVC obstruction underwent MRV scans. These scans were evaluated for morphology of the obstruction and compared with digital subtraction angiography (DSA) images. RESULTS Using DSA, we determined that 47 patients had complete obstruction and 9 had partial obstruction. MRV scans revealed 6 cases of partial obstruction. Using MRV, we determined the morphology of the proximal and distal ends of the complete obstructions in the IVC. We classified our observations into cone, plateau, and irregular subtypes. Both DSA and MRV scans were compared to assess the consistency between two methods. MRV demonstrated high sensitivity (100%) for diagnosing a complete obstruction of the IVC, and its specificity was 66.7%. The positive and negative predictive values of MRV were 94% and 100%, respectively. CONCLUSIONS MRV imaging is a valuable alternative to DSA for detection of obstructions in the IVC in Budd-Chiari syndrome, particularly in the distal end, which could expedite the decision making for interventional treatment programmes. However, MRV imaging is less suitable for observing the morphology of the proximal ends of obstructions due to the limitations of the scanning plane and the influence of pseudo shadows.

Abstract
OBJECTIVE The aim of this study was to improve the understanding of FBA in children and to decrease the rate of misdiagnosis, missed diagnosis and morbidity. PATIENTS AND METHODS We analyzed the clinical features and the three-dimensional reconstructed CT images of 590 children with foreign body aspiration (FBA) in the Xuzhou area of the Jiangsu province. RESULTS CT imaging revealed common complications of FBA including emphysema (n = 379), pneumonia (n = 174), and atelectasis (n = 26). The remaining 120 patients had no visible complications on the three-dimensional reconstructed CT images. Serious complications including pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumatorrhachis could also be observed. The types of foreign bodies were diverse: the most common were peanuts and sunflower seeds. The diagnostic accuracy of the three-dimensional CT imaging was high, with a sensitivity and specificity of 99.83% and 99.89%, respectively. CONCLUSIONS 3D CT imaging is an accurate, non-invasive technique to evaluate children with suspected FBA that can help decrease the rate of misdiagnosis and eliminate a delay in treatment for this potentially life-threatening condition.

Abstract
OBJECTIVE Despite growing popularity of ketamine misuse in Asia, there is a lack of a validated instrument to measure the severity of ketamine dependence. Psychometric properties of Chinese Severity of Dependence Scale for ketamine (C-SDS-K) were examined in a sample of treatment-seeking ketamine users in Hong Kong. METHODS A total of 80 treatment-seeking ketamine users were recruited from 3 treatment centres. The C-SDS-K was administered to assess their severity of dependence on ketamine in the previous month. The diagnosis of their ketamine misuse as per the DSM-IV criteria, and the count of dependence criteria fulfilled in the previous month were determined by the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). RESULTS The C-SDS-K showed high internal consistency (α = 0.74) and test-retest reliability (intraclass correlation coefficient = 0.95). Total score of C-SDS-K correlated positively with frequency (rs = 0.73, p < 0.001) and dose (rs = 0.89, p < 0.001) of ketamine use per week in the previous month, duration of regular ketamine use (rs = 0.28, p = 0.01), and the count of DSM-IV ketamine dependence criteria met in the previous month (rs = 0.84, p < 0.001). All items loaded strongly on a single factor (factor loading ≥ 0.60) in principal component analysis. CONCLUSION The findings support SDS as a reliable and valid tool for measuring the severity of dependence in the treatment-seeking population of Chinese ketamine users.

Abstract
BACKGROUND The Braunwald classification and TIMI (Thrombolysis In Myocardial Infarction) risk score are used to stratify cardiovascular risk in patients with unstable angina (UA). However, these scores have a limited capacity in the practice of cardiology. OBJECTIVES This study sought to develop a new score, based on blood biomarkers and coronary computed tomographic angiography (CCTA) characteristics, for patients with UA. PATIENTS AND METHODS The study group consisted of 201 patients with confirmed UA. Follow-up time was 1 year; major adverse cardiac events (MACEs) included cardiovascular death, recurrent acute coronary syndrome (ACS), and re-admission to hospital. Blood biomarkers including high-sensitivity cardiac troponin T (Hs-cTnT), high-sensitivity C-reactive protein (Hs-CRP), myeloperoxidase (MPO) N-terminal pro-B-type natriuretic peptide (NT-proBNP), and ischemia-modified albumin (IMA) were measured. CCTA characteristics such as stenosis, plaque, epicardial fat volume (EFV), and calcification were evaluated. After analysis of relationships, the novel risk BETTER (BiomarkErs and compuTed Tomography scorE on Risk stratification) score was assessed in 201 patients. RESULTS In all, 25 MACEs (12.44 %) occurred: 2 cardiac deaths (1.00 %), 13 non-fatal myocardial infarctions (6.47 %), 10 recurrent ACS and re-admission in hospital (4.96 %). Serum levels of MPO, NT-proBNP, Hs-TnT, Hs-CRP, and IMA were correlated with MACEs (r = 0.20, r = 0.40, r = 0.18, r = 0.24, p < 0.01, respectively; r = 0.12, p > 0.05). CCTA characteristics of stenosis, plaque, EFV, and calcification were significantly correlated with MACEs (r = 0.53, r = 0.57, r = 0.42, and r = 0.52, all p < 0.01 respectively) and were significantly higher in the MACEs group than in the non-MACEs group. Thus, a new risk score was created combining biomarkers and CCTA statistics into a Cox multivariable for risk prediction of 1-year MACEs: BETTER risk score = MPO•0.1 + Hs-TnT•50 + Hs-CRP•0.4 + stenosis•9 + plaque•13 + EFV•0.2. The areas under the curve (AUC) for the prediction by Hs-cTnT, Hs-CRP, and MPO were 0.536 (95 % CI 0.409-0.662), 0.745 (95 % CI 0.641-0.850), and 0.650 (95 % CI 0.541-0.760), respectively. The AUC for the prediction of CCTA characteristics of stenosis, plaque, and EFV were 0.905 (95 % CI 0.860-0.950), 0.912 (95 % CI 0.867-0.957), and 0.835 (95 % CI 0.752-0.917), respectively. In addition, the AUC was 0.621 (95 % CI 0.492-0.750) for the Braunwald classification and 0.680 (95 % CI 0.559-0.801) for the TIMI score. The AUC for the BETTER risk score was 0.937 (95 % CI 0.902-0.972). CONCLUSION The BETTER risk score is new tool specifically developed for patients with UA. The score displays higher prediction accuracy in terms of discrimination and calibration than other currently available scores for risk stratification.

Abstract
Here, 248 endophytic bacterial strains were isolated to assess the distribution and population diversity of endophytic bacteria in ginger plants. A total of 10.4 x 10(4) to 20.2 x 10(4) CFU/g fresh weight endophytic bacteria of different growth stages were isolated. Maximum bacterium numbers were obtained at the seedling stage. A total of 107 functional strains were screened, including 17 antibacterial strains and 90 indole acetic acid-producing strains. Based on 16S rDNA sequence restriction fragment length polymorphism and 16S rDNA sequences, these 107 strains were mapped and grouped into 16 genera. Bacillus and Pseudomonas were the dominant genera; however, the bacteria belonged to a tremendous range of genera, with the highest species richness being observed at the seedling stage. Sixteen strains exhibited antimicrobial activity against Pythium myriotylum Drechsler, while 7 strains exhibited antimicrobial activity against Phyllosticta zingiberi Hori. Bacillus was the dominant antibacterial strain. Pseudomonas fluorescens, B. megaterium, and Enterobacter ludwigii produced remarkably high levels of IAA. Only a few endophytic bacterial strains were inhibited in fresh ginger juice. Most of these strains were present during seedling stage, including Roseateles depolymerans, Chryseobacterium taiwanense, E. ludwigii, Agrobacterium larrymoorei, P. fluorescens, and Bacillus amyloliquefaciens. This study indicates that the community of endophytic bacteria in ginger changes with the synthesis of antibacterial substances.
