Abstract
OBJECTIVES Lung cancer is one of the most common malignant tumors, but the etiology is not yet clear. Our study aims to deepen the understandings about the mechanisms of lung cancer via screening relevant key genes and functional pathways. MATERIALS AND METHODS Microarray data set was collected and differentially expressed genes (DEGs) were selected out. KEGG pathway analysis and Gene Ontology (GO) enrichment analysis were performed for the DEGs. Interaction networks were constructed for the lung cancer-related DEGs with information from Human Protein Reference Database (HRPD) to screen out potential biomarkers. RESULTS Functional annotation revealed that cell cycle, DNA replication, immune system, and signal molecules and interactions were significantly over-represented in all the DEGs, suggesting their close involvement in the development of lung cancer. 40 genes with high degree, betweenness and clustering coefficient were identified from the interaction network. 26 out of them are known cancer genes according to the database F-census. Besides, 4 biomarkers were revealed through analyzing their interactions with oncogenes. CONCLUSIONS Our study not only advances the understandings about the molecular mechanisms of lung cancer, but also provides several potential biomarkers for clinical use.

Abstract
BACKGROUND It is not clear whether the progressive changes in brain microstructural deficits documented in previous longitudinal magnetic resonance imaging (MRI) studies might be due to the disease process or to other factors such as medication. It is important to explore the longitudinal alterations in white-matter (WM) microstructure in antipsychotic-naive patients with first-episode schizophrenia during the very early phase of treatment when relatively 'free' from chronicity. METHOD Thirty-five patients with first-episode schizophrenia and 22 healthy volunteers were recruited. High-resolution diffusion tensor imaging (DTI) was obtained from participants at baseline and after 6 weeks of treatment. A 'difference map' for each individual was calculated from the 6-week follow-up fractional anisotropy (FA) of DTI minus the baseline FA. Differences in Positive and Negative Syndrome Scale (PANSS) scores and Global Assessment of Functioning (GAF) scores between baseline and 6 weeks were also evaluated and expressed as a 6-week/baseline ratio. RESULTS Compared to healthy controls, there was a significant decrease in absolute FA of WM around the bilateral anterior cingulate gyrus and the right anterior corona radiata of the frontal lobe in first-episode drug-naive patients with schizophrenia following 6 weeks of treatment. Clinical symptoms improved during this period but the change in FA did not correlate with the changes in clinical symptoms or the dose of antipsychotic medication. CONCLUSIONS During the early phase of treatment, there is an acute reduction in WM FA that may be due to the effects of antipsychotic medications. However, it is not possible to entirely exclude the effects of underlying progression of illness.

Abstract
Previous evidence has shown that Parkinson disease (PD) has a heritable component, but only a small proportion of the total genetic contribution to PD has been identified. Genetic heterogeneity complicates the verification of proposed PD genes and the identification of new PD susceptibility genes. Our approach to overcome the problem of heterogeneity is to study a population isolate, the mid-western Amish communities of Indiana and Ohio. We performed genome-wide association and linkage analyses on 798 individuals (31 with PD), who are part of a 4,998 member pedigree. Through these analyses, we identified a region on chromosome 5q31.3 that shows evidence of association (p value < 1 × 10(-4)) and linkage (multipoint HLOD = 3.77). We also found further evidence of linkage on chromosomes 6 and 10 (multipoint HLOD 4.02 and 4.35 respectively). These data suggest that locus heterogeneity, even within the Amish, may be more extensive than previously appreciated.

Cross sections of 45Sc(n, 2n)44m,g Sc reactions and their isomeric cross section ratios σ
m
/σ
g have been measured at three neutron energies between 13.5 and 14.8 MeV using the activation technique. The pure cross section of the groundstate was then obtained by utilizing the absolute cross section of the metastable state and analysis methods of residual nuclear decay. The monoenergetic neutron beam was produced via the 3H(d, n)4He reaction. The cross sections were also estimated with the TALYS-1.2 nuclear model code using different level density options, at neutron energies varying from the reaction threshold to 20 MeV. Results are also discussed and compared with some corresponding values found in the literature.

Abstract
Efforts to define the genetic architecture underlying variable statin response have met with limited success, possibly because previous studies were limited to effect based on a single dose. We leveraged electronic medical records (EMRs) to extract potency (ED50) and efficacy (Emax) of statin dose-response curves and tested them for association with 144 preselected variants. Two large biobanks were used to construct dose-response curves for 2,026 and 2,252 subjects on simvastatin and atorvastatin, respectively. Atorvastatin was more efficacious, was more potent, and demonstrated less interindividual variability than simvastatin. A pharmacodynamic variant emerging from randomized trials (PRDM16) was associated with Emax for both. For atorvastatin, Emax was 51.7 mg/dl in subjects homozygous for the minor allele vs. 75.0 mg/dl for those homozygous for the major allele. We also identified several loci associated with ED50. The extraction of rigorously defined traits from EMRs for pharmacogenetic studies represents a promising approach to further understand the genetic factors contributing to drug response.

Abstract
OBJECTIVE To evaluate our early experience with endovascular revascularization in patients with acute thromboembolic occlusion of the superior mesenteric artery (SMA). METHODS A retrospective review was conducted of all patients who underwent endovascular revascularization for acute thromboembolic SMA occlusion from May 2005 to May 2012. Endovascular revascularization was performed using aspiration, intra-arterial thrombolysis, and adjunctive stent-placement techniques. Laparotomy was performed if the patient developed clinical signs of advanced bowel ischemia after endovascular procedure. RESULTS Twenty-one patients underwent endovascular revascularization for acute thromboembolic SMA occlusion. All presented with acute-onset abdominal pain. Three patients had rebound tenderness before the procedure. Computed tomography angiography revealed complete occlusion in seven cases and incomplete occlusion in 14 cases, with no evidence of free gas or bowel necrosis. The median duration from onset of symptoms to revascularization was 8.7 ± 4.1 hours (range, 2-18 hours). Completely successful endovascular revascularization occurred in six cases (aspiration alone, 3 cases; combined aspiration and urokinase, 3 cases); partial success was achieved in 15 cases (aspiration alone, 4 cases; combined aspiration and urokinase, 10 cases; and combined aspiration, urokinase, and stent placement, 1 case). Laparotomy was required in five patients, all of whom had SMA main trunk complete occlusion and required small bowel resection. The 30-day mortality for all patients was 9.5%. During a median follow-up of 26 months, 15 patients remained asymptomatic, three patients reported occasional abdominal pain, and one patient had temporary short-bowel syndrome. CONCLUSIONS Percutaneous revascularization is a promising alternative to surgery for acute SMA occlusion in selected patients who have no signs of advanced bowel ischemia. Early diagnosis followed by prompt endovascular intervention with close postprocedural monitoring is key. Laparotomy is indicated in patients who develop new or worsening signs of peritonism after endovascular procedure, particularly in those who had complete occlusion of the main trunk of the SMA.

Abstract
BACKGROUND Evidence shows that cognitive deficits and white matter (WM) dysconnectivity can independently be associated with clinical manifestations in schizophrenia. It is important to explore this triadic relationship in order to investigate whether the triplet could serve as potential extended endophenotypes of schizophrenia. METHOD Diffusion tensor images and clinical performances were evaluated in 122 individuals with first-episode schizophrenia and 122 age- and gender-matched controls. In addition, 65 of 122 of the patient group and 40 of 122 controls were measured using intelligence quotient (IQ) testing. RESULTS The schizophrenia group showed lower fractional anisotropy (FA) values than controls in the right cerebral frontal lobar sub-gyral (RFSG) WM. The schizophrenia group also showed a significant positive correlation between FA in the RFSG and performance IQ (PIQ) ; in turn, their PIQ score showed a significant negative correlation with negative syndromes. CONCLUSIONS Overall, these findings support the hypothesis that WM deficits may be a core deficit that contributes to cognitive deficits as well as to negative symptoms.

Abstract
Capsular block syndrome (CBS) has been known to occur as a rare complication of cataract surgery with continuous curvilinear capsulorhexis and a posterior-chamber lens implant. Typically, it presents with reduced vision in the early postoperative period and is characterised by a forward displacement of the posterior-chamber intra-ocular lens and an accumulation of intra-capsular opaque material. Management of CBS is usually by Nd:YAG laser capsulotomy. In this report, we describe a unique case of very-delayed-onset CBS with good visual acuity, occurring 8 years after surgery. It was treated successfully with surgical removal of the opaque material.

Abstract
BACKGROUND Previous studies have shown that complement activation is required for intestinal ischemia-reperfusion (IIR)-induced tissue damage. Cobra venom factor (CVF), a structural and functional homolog to the activated form of C3 (the central component of the complement system), can cause exhaustive activation of the alternative pathway and deplete the complement components. AIM This study aims to investigate the effect of CVF pretreatment on acute lung injury induced by IIR in rats. MATERIALS AND METHODS Lung injury was induced by clamping superior mesenteric artery (SMA) for 60 min followed by 4 h of reperfusion. CVF was given via the tail vein 24 h before the operation. RESULTS Histological results as well as lung edema determination and permeability assay showed the severe damages were induced in the lungs of rats in the IIR group, accompanying with the increases in the levels of pulmonary malondialdehyde (MDA), myeloperoxidase (MPO) activity, intercellular adhesion molecule-1 (ICAM-1), interleukin (IL)-8. Remarkably, CVF pretreatment significantly attenuated the morphological lung injury, lung edema and lung permeability, reduced the increase of the levels of MDA, MPO, ICAM-1 and IL-8 induced by IIR. In addition, the severe damage of intestinal and elevation of plasma diamine oxidase activity in the IIR rats were significantly alleviated by CVF pretreatment. CONCLUSIONS CVF pretreatment could significantly reduce the acute lung injury induced by IIR. The mechanism might include, at least in part, the inhibition of oxidant generation, infiltration of neutrophils, ICAM-1 expression and IL-8 release. CVF might be an efficient reagent for preventing the IIR injuries in clinical condition.

Abstract
We report on a clear solar-cycle variation of the Sun’s shadow in the 10 TeV cosmic-ray flux observed by the Tibet air shower array during a full solar cycle from 1996 to 2009. In order to clarify the physical implications of the observed solar cycle variation, we develop numerical simulations of the Sun’s shadow, using the potential field source surface model and the current sheet source surface (CSSS) model for the coronal magnetic field. We find that the intensity deficit in the simulated Sun’s shadow is very sensitive to the coronal magnetic field structure, and the observed variation of the Sun’s shadow is better reproduced by the CSSS model. This is the first successful attempt to evaluate the coronal magnetic field models by using the Sun’s shadow observed in the TeV cosmic-ray flux.

Abstract
A single-step solid-state synthetic approach was developed for the synthesis of silicon-coated carbon nanotube (CNT) core/shell structures. This was achieved through laser-induced melting and evaporation of CNT-deposited Si substrates using a continuous wavelength CO2 laser. The synthesis location of the CNT/Si structures was defined by the laser-irradiated spots. The thickness of the coating was controlled by tuning the laser power and synthesis time during the coating process. This laser-based synthetic technique provides a convenient approach for solid-state, controllable, gas-free, simple and cost-effective fabrication of CNT/Si core/shell structures.

Abstract
AIM To determine whether the cisplatin plus etoposide (EP) combination was more efficacious and less toxic than other platinum-based regimens for patients with extensive-stage small-cell lung cancer. METHODS We performed an extensive literature search (from their inception to July 2010). Two reviewers independently assessed search results and methodological quality of included studies. Pooled hazard ratios (HRs) and relative risks (RRs) were calculated according to a random-effects model. RESULTS Twelve randomised, controlled trials involving seven different platinum-based chemotherapy regimens were included into this meta-analysis. The meta-analysis showed that compared with EP regimen, irinotecan plus cisplatin (IP) might decrease the risk of death (HR = 0.87, 95% confidence interval (CI) 0.78-0.97, P = 0.01) (five trials), unlike the sensitivity analysis (HR = 0.91, 95% CI 0.81-1.02, P = 0.12), progression-free survival (HR = 0.95, 95% CI 0.86-1.05, P = 0.28) and overall response rate (RR 1.08, 95% CI 0.93-1.24) that were not superior for IP. IP regimen produced more non-haematological toxicities and less haematological toxicities. One trial found that etoposide + cisplatin + epirubicin + cyclophosphamide and cisplatin + etoposide + ifosfamide regimen might prolong the overall survival respectively. Etoposide + cisplatin + epirubicin + cyclophosphamide regimen also might improve progression-free survival but with high rate of haematological toxicities. None of the other trials included in the study demonstrated a significant improvement in survival. CONCLUSIONS There is no strong evidence that any clinical advantage for extensive small-cell lung carcinoma patients requiring chemotherapy when comparing EP with other platin-based regimens, with exception of IP that might prolong overall survival. The decision to prescribe which chemotherapy should take into consideration both cost and treatment preference.

Abstract
We prospectively followed 171 patients who underwent bilateral unicompartmental knee replacement (UKR) over a period of two years. Of these, 124 (72.5%) underwent a simultaneous bilateral procedure and 47 (27.5%) underwent a staged procedure. The mean cumulative operating time and length of hospital stay were both shorter in the simultaneous group, by 22.5 minutes (p < 0.001) and three days (p < 0.001), respectively. The mean reduction in haemoglobin level post-operatively was greater by 0.15 g/dl in the simultaneous group (p = 0.023), but this did not translate into a significant increase in the number of patients requiring blood transfusion (p = 1.000). The mean hospital cost was lower by $8892 in the simultaneous group (p < 0.001). There was no significant difference in the rate of complications between the groups, and at two-year follow-up there was no difference in the outcomes between the two groups. We conclude that simultaneous bilateral UKR can be recommended as an appropriate treatment for patients with bilateral medial compartment osteoarthritis of the knee.
