Abstract
Presented study aims to explore the predictive values of serum microRNA-22 (miR-22) and miR-126 levels for non-small cell lung cancer (NSCLC) development and metastasis.A total of 127 NSCLC patients who were admitted in the First People's Hospital of Yancheng City from May, 2013 to May, 2015 were selected as the case group, including 71 cases of adenocarcinoma and 56 cases of squamous cell carcinoma. There were 112 healthy individuals selected as the control group. The qRT-PCR was performed to testify the serum miR-22 and miR-126 levels. Logistic regression analysis was conducted to analyze independent factors influencing NSCLC metastasis and receiver operating characteristic (ROC) curve was drawn to analyze the sensitivity and specificity of serum miR-22 and miR-126 levels in predicting NSCLC developments and metastasis.The serum miR-22 level was significantly higher in the case group than that in the control group, while the serum miR-126 level was lower in the case group as compared with that in the control group. Compared with squamous cell carcinoma patients, serum miR-22 level significantly increased, while serum miR-126 level decreased in patients with adenocarcinoma. Patients at III + IV stage showed increased serum miR-22 level and relatively decreased serum miR-126 level as compared to patients at I + II stage. Serum miR-22 level elevated in patients with metastasis; in contrast serum miR-126 level reduced in comparison to those without metastasis. In patients with familial inheritance, serum miR-22 level increased but serum miR-126 level decreased as compared to those without familial inheritance. The specificity and sensitivity of serum miR-22 and miR-126 levels in predicting NSCLC development were 99.11%, 84.30%, 82.68% and 96.40%, respectively. The specificity and sensitivity of serum miR-22 and miR-126 levels in predicting NSCLC metastasis were 59.74%, 96.00%, 84.00% and 62.30%, respectively.Results indicated that serum miR-22 and miR-126 levels may be used as the predicative biomarkers for NSCLC development and metastasis.

Abstract
OBJECTIVE To evaluate the etiologic heterogeneity between medial and lateral tibiofemoral radiographic osteoarthritis (ROA). METHODS Knees without medial or lateral tibiofemoral ROA at baseline were followed for 60-month in Multicenter Osteoarthritis Study (MOST) and for 48-month in Osteoarthritis Initiative (OAI). We examined the relation of previously reported risk factors to incident medial and lateral tibiofemoral ROA separately and determined the etiology heterogeneity with a ratio of rate ratios (RRs) (i.e., the RR for medial tibiofemoral ROA divided by the RR for lateral tibiofemoral ROA) using a duplication method for Cox proportional hazard regression. RESULTS Of 2,016 participants in MOST, 436 and 162 knees developed medial or lateral tibiofemoral ROA, respectively. Obesity and varus malalignment were 95% and 466% more strongly associated with incident medial tibiofemoral ROA than with lateral tibiofemoral ROA, respectively (ratios of RRs, 1.95 [95% confidence interval (CI):1.05-3.62] and 5.66 [95% CI:3.20-10.0]). In contrast, the associations of female sex and valgus malalignment with incident medial tibiofemoral ROA were weaker or in an opposite direction compared with lateral tibiofemoral Osteoarthritis (OA) (ratios of RRs, 0.40 [95% CI:0.26-0.63] and 0.20 [95% CI:0.12-0.34], respectively). Older age tended to show a weaker association with incident medial tibiofemoral ROA than with incident lateral tibiofemoral ROA. No heterogeneity was observed for the relation of race, knee injury, or contralateral knee ROA. These findings were closely replicated in OAI. CONCLUSION Risk factor profiles for medial and lateral tibiofemoral ROA are different. These results can provide a framework for the development of targeted prevention and potential treatment strategies for specific knee OA subtypes.

Abstract
Precision results on cosmic-ray electrons are presented in the energy range from 0.5 GeV to 1.4 TeV based on 28.1×10^{6} electrons collected by the Alpha Magnetic Spectrometer on the International Space Station. In the entire energy range the electron and positron spectra have distinctly different magnitudes and energy dependences. The electron flux exhibits a significant excess starting from 42.1_{-5.2}^{+5.4} GeV compared to the lower energy trends, but the nature of this excess is different from the positron flux excess above 25.2±1.8 GeV. Contrary to the positron flux, which has an exponential energy cutoff of 810_{-180}^{+310} GeV, at the 5σ level the electron flux does not have an energy cutoff below 1.9 TeV. In the entire energy range the electron flux is well described by the sum of two power law components. The different behavior of the cosmic-ray electrons and positrons measured by the Alpha Magnetic Spectrometer is clear evidence that most high energy electrons originate from different sources than high energy positrons.

Abstract
Abstract
Background: Both the Aphinity and ExteNET trials for anti-HER2 targeted agents were challenged in showing significant benefit of added HER2-targeted treatment. The findings suggested biological heterogeneity in HER2+ cancers, not entirely identified by IHC/FISH, requiring more nuanced biomarkers to clearly identify patient subsets who may derive benefit from new HER2-targeted agents. We have previously shown that BluePrint (80-gene) molecular subtyping reclassifies nearly half of HER2+/ER+ patients to Luminal-type with differential neoadjuvant treatment response (Whitworth, Ann Surg Oncol 2014; Whitworth, ASCO 2018). Here, we evaluated the reclassification rate in the real-world diagnostic setting. Methods: Physicians regularly provide pathology reports to Agendia, Inc for samples which are processed for MammaPrint (70-gene signature) and BluePrint molecular assays as part of routine diagnostic care. For this analysis, 4986 sequentially available pathology reports (submitted between October 2016 to October 2017) were reviewed; HER2 and ER IHC results were captured. The molecular subtype was compared to IHC/FISH status. Results: HER2 IHC/FISH results were available for 1568 samples. Of those, 85% (1330/1568) were HER2-nonamplified, 10% (153/1568) were HER2-equivocal, and 5% (85/1568) were HER2-amplified by IHC/FISH. Of the HER2-nonamplified tumors, BluePrint reclassified 0.1% (2/1330) as HER2-type. Of the HER2-equivocal tumors, none were HER2-type by BluePrint; 91% (139/153) were Luminal-type and 9% (14/153) were Basal-type. Of the HER2-amplified tumors, 15% (13/85) were dominant HER2-type, 79% (67/85) were dominant Luminal-type, and 6% (5/85) were Basal-type. Conclusions: In this set of tumors identified as HER2-amplified by IHC/FISH, BluePrint reclassified 85% of tumors to non-HER2 molecular subtypes, mostly Luminal-type for ER-positive tumors and Basal-type for ER-negative tumors. Moreover, BluePrint gave clarity where IHC/FISH could not, classifying all HER2-equivocal tumors to non-HER2 subtypes. Additional therapeutic options should be explored for HER2+/ER+ BluePrint Luminal-type patients who have observed much lower pCR rates versus BluePrint HER2-type patients (12% vs. 51%, respectively; Lee, AACR 2018).

Abstract
Acute kidney injury (AKI) is an increasing clinical problem that is associated with chronic kidney disease progression. Cannabinoid receptor 2 (CB2) activation has been shown to mitigate some of the deleterious tubular effects due to AKI, but its role on the renal vasculature has not been fully described. In this study, we investigated the effects of our novel CB2 receptor agonist, SMM-295, on renal vasculature by assessing cortical perfusion with laser Doppler flowmetry and changes in luminal diameter with isolated afferent arterioles. In this study, intravenously infused SMM-295 (6 mg/kg) significantly increased cortical renal perfusion (13.8 ± 0.6%; P < 0.0001; n = 7) compared with vehicle (0.1 ± 1.5%; n = 10) normalized to baseline values in anesthetized C57BL/6J mice. This effect was not dependent upon activation of the CB1 receptor (met-anandamide; 6 mg/kg iv) and was predominantly abolished in Cnr2 knockout mice with SMM-295 (6 mg/kg iv). Ablation of the renal afferent nerves with capsaicin blocked the SMM-295-dependent increase in renal cortical perfusion, and the increased renal blood flow was not dependent upon products synthesized by cyclooxygenase or nitric oxide synthase. The increased renal perfusion by CB2 receptor activation is also attributed to a direct vascular effect, since SMM-295 (5 μM) engendered a significant 37 ± 7% increase ( P < 0.0001; n = 4) in luminal diameters of norepinephrine-preconstricted afferent arterioles. These data provide new insight into the potential benefit of SMM-295 by activating vascular and nonvascular CB2 receptors to promote renal vasodilation, and provide a new therapeutic target to treat renal injuries that impact renal blood flow dynamics.

Abstract
Precision measurements of cosmic ray positrons are presented up to 1 TeV based on 1.9 million positrons collected by the Alpha Magnetic Spectrometer on the International Space Station. The positron flux exhibits complex energy dependence. Its distinctive properties are (a) a significant excess starting from 25.2±1.8 GeV compared to the lower-energy, power-law trend, (b) a sharp dropoff above 284_{-64}^{+91} GeV, (c) in the entire energy range the positron flux is well described by the sum of a term associated with the positrons produced in the collision of cosmic rays, which dominates at low energies, and a new source term of positrons, which dominates at high energies, and (d) a finite energy cutoff of the source term of E_{s}=810_{-180}^{+310} GeV is established with a significance of more than 4σ. These experimental data on cosmic ray positrons show that, at high energies, they predominantly originate either from dark matter annihilation or from other astrophysical sources.

Abstract
OBJECTIVE Our aim was to evaluate the general applicability, feasibility, and safety of robot-assisted radical prostatectomy (RARP) in Chinese renal allograft patients for prostate cancer removal. PATIENTS AND METHODS A 62-year-old patient diagnosed as having biopsy-proven localized prostate cancer in March 2016 who had undergone renal transplant 12 years ago was studied. The preoperative prostate-specific antigen value was determined to be 11.82 ng/mL and the Gleason score was determined to be 3 + 3. The RARP was carried out using a transperitoneal and posterior approach with 5 ports in May 2016. The most important technique was ensuring that the transplanted kidney and ureter remained untouched during the surgery. Only the right obturator lymph nodes were dissected because the renal allograft was overlying the iliac vessels. RESULTS The RARP was successfully concluded following 230 minutes with an estimated blood loss of 200 mL. There were no postoperative complications. Final pathology was T2cN0M0, Gleason 3 + 3. Following catheter removal, the patient was completely continent and was discharged with no change in serum creatinine or glomerular filtration rate levels. During a 21-month follow-up, unobstructed urination, no incontinence, no biochemical recurrence, and normal kidney function were observed. CONCLUSION RARP in Chinese renal allograft patients is a feasible method that can be accomplished with no injuries to the transplanted kidney or ureter and is achieved with favorable oncological and functional outcomes. In addition, post-kidney transplant male patients are recommended to have routine prostate-specific antigen screening for the early detection of prostate cancer.

Abstract
Alloy design based on single–principal-element systems has approached its limit for performance enhancements. A substantial increase in strength up to gigapascal levels typically causes the premature failure of materials with reduced ductility. Here, we report a strategy to break this trade-off by controllably introducing high-density ductile multicomponent intermetallic nanoparticles (MCINPs) in complex alloy systems. Distinct from the intermetallic-induced embrittlement under conventional wisdom, such MCINP-strengthened alloys exhibit superior strengths of 1.5 gigapascals and ductility as high as 50% in tension at ambient temperature. The plastic instability, a major concern for high-strength materials, can be completely eliminated by generating a distinctive multistage work-hardening behavior, resulting from pronounced dislocation activities and deformation-induced microbands. This MCINP strategy offers a paradigm to develop next-generation materials for structural applications.

CircRNAs exert gene regulatory effects by sequestering target microRNAs (miRNAs) and play a vital role in the onset and development of disease. Until recently, little has been known about the expression, regulation and biological function of circRNAs in both health and chronic hepatitis B (CHB).To identify hepatic circRNAs associated with CHB, we performed RNA sequencing using liver biopsies from untreated CHB patients and controls. We then established a bioinformatics pipeline for identification of CHB-associated circRNAs and in silico analysis of the circRNA-miRNA-mRNA pathways. We used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to confirm these results. The profiles of hepatic circRNA expression were significantly different in CHB compared with controls, with a total of 99 dysregulated circRNAs identified to be correlated with CHB. Computational analysis of the circRNA-miRNA-mRNA pathways revealed a large number of miRNAs (665), which were putatively targeted by the differentially expressed hepatic circRNAs. Interestingly, four of the predicted CHB-related circRNA-miRNA-mRNA pathways were found to be involved in the pathogenesis of HBV infection and progression of HBV-associated liver disease. Among these pathways, regression analysis of gene expression revealed a strong positive correlation between hsa_circ_0000650 and TGFβ2 and a negative correlation between hsa_circ_0000650 and miR-6873-3p, which hinted that hsa_circ_0000650 interacted with TGFβ2 mediated by miR-6873-3p. This study firstly demonstrates that patients with CHB present different profiles of hepatic circRNAs and circRNA/miRNA interactions. Thus, circRNAs have promise as novel mechanisms underlying the pathogenesis and progression of CHB.

Abstract
Hepatitis B e antigen (HBeAg) seroconversion is considered to have significantly favourable clinical outcomes for patients with chronic hepatitis B (CHB). However, inconsistent study results suggest that hepatocellular carcinoma (HCC) still occurs in patients with HBeAg seroconversion. We performed a systematic review and meta-analysis to determine the incidence of HCC in patients with CHB after HBeAg seroconversion. Web of Science, PubMed and Embase databases were searched through January 2017. The incidence of HCC in CHB patients after HBeAg seroconversion was pooled using a random-effects model or fix-effects model. Sixteen studies were finally included, involving 4910 patients with HBeAg seroconversion. The overall pooled proportion suggested that 3.33% (95% confidence interval (CI): 2.28%-4.58%) of patients with CHB develop HCC despite HBeAg seroconversion. In patients with HBeAg seroconversion without cirrhosis, the pooled proportion of HCC development was 0.94% (95% CI: 0.15%-2.4%). Moreover, patients with cirrhosis, active hepatitis, or aged greater than 40 years at the time of HBeAg seroconversion were at significantly higher risk for HCC development. HBeAg seroconversion was significantly associated with a reduced risk of HCC compared with persistently positive HBeAg (RR = 0.58, 95% CI: 0.35-0.97, P = .04). Despite the reduced risk with HBeAg seroconversion, HCC can still occur in a proportion of patients with CHB after HBeAg seroconversion. Long-term monitoring is needed for patients with established cirrhosis, active hepatitis or those older than 40 years at the time of HBeAg seroconversion.

Abstract
Selecting functional genes is essential for analyzing microarray data. Among many available feature (gene) selection approaches, the ones on the basis of the large margin nearest neighbor receive more attention due to their low computational costs and high accuracies in analyzing the high-dimensional data. Yet, there still exist some problems that hamper the existing approaches in sifting real target genes, including selecting erroneous nearest neighbors, high sensitivity to irrelevant genes, and inappropriate evaluation criteria. Previous pioneer works have partly addressed some of the problems, but none of them are capable of solving these problems simultaneously. In this paper, we propose a new local-nearest-neighbors-based feature weighting approach to alleviate the above problems. The proposed approach is based on the trick of locally minimizing the within-class distances and maximizing the between-class distances with the nearest neighbors rule. We further define a feature weight vector, and construct it by minimizing the cost function with a regularization term. The proposed approach can be applied naturally to the multi-class problems and does not require extra modification. Experimental results on the UCI and the open microarray data sets validate the effectiveness and efficiency of the new approach.

Abstract
A precision measurement of the nitrogen flux with rigidity (momentum per unit charge) from 2.2 GV to 3.3 TV based on 2.2×10^{6} events is presented. The detailed rigidity dependence of the nitrogen flux spectral index is presented for the first time. The spectral index rapidly hardens at high rigidities and becomes identical to the spectral indices of primary He, C, and O cosmic rays above ∼700 GV. We observed that the nitrogen flux Φ_{N} can be presented as the sum of its primary component Φ_{N}^{P} and secondary component Φ_{N}^{S}, Φ_{N}=Φ_{N}^{P}+Φ_{N}^{S}, and we found Φ_{N} is well described by the weighted sum of the oxygen flux Φ_{O} (primary cosmic rays) and the boron flux Φ_{B} (secondary cosmic rays), with Φ_{N}^{P}=(0.090±0.002)×Φ_{O} and Φ_{N}^{S}=(0.62±0.02)×Φ_{B} over the entire rigidity range. This corresponds to a change of the contribution of the secondary cosmic ray component in the nitrogen flux from 70% at a few GV to <30% above 1 TV.

Abstract
Objective: To compare the cannulated screw internal fixation (IF) and hemiarthroplasty (HA) for displaced femoral neck fracture with cost-utility analysis (CUA). Methods: From January 2014 to August 2015, a total of 87 patients above 60 years old with displaced femoral neck fracture were admitted into the study and divided into 2 groups according to surgery type. There were 41 cases in IF group and 46 cases in HA group. During 1 year follow-up we collected the total cost due to fracture and applied EQ-5D index to evaluate the clinical effects. The value of EQ-5D index will be transformed to quality adjusted life year (QALY). Eventually the data including cost and QALY were used to calculate the cost utility ratio (CUR) for patients in each group. Results: All the patients completed the operation successfully. The total cost of IF and HA was 45 796 yuan and 56 657 yuan (P<0.05), while the QALY was 0.79 and 0.83 respectively (P>0.05). The CUR showed that patients in IF and HA group spent 57 970 yuan and 68 261 yuan for each QALY which means patients in HA group spent more 10 292 yuan for each QALY than that in IF group. Conclusions: Both IF and HA can provide satisfactory clinical outcome in 1 year follow-up, however the total cost of IF was obviously less than HA. Therefore IF may be more cost-effective for the treatment of displaced femoral neck fracture in terms of health economics.

Abstract
AIM To study the prognostic factors of gastric cancer (GC) patients who were classified with stage III disease according to the newest TNM classification. METHODS This study retrospectively enrolled 279 patients who underwent radical gastrectomy from January 2012 to December 2014 at our hospital and who were diagnosed with stage III GC according to the new 8th edition of the TNM classification. The patient data that were collected included age, sex, pathological parameters, survival, lymph node ratio, neo-adjuvant chemotherapy with oxaliplatin and S-1, and operation type. The characteristics, survival, and prognostic factors of the patients were analyzed by univariate and multivariate analyses. RESULTS The median OS of the patients after curative surgery was 19 months, and the 3-year survival rate (3-YSR) was 25.3%. A univariate analysis showed that tumor location (P = 0.01), neo-adjuvant chemotherapy (P = 0.005), pathological T stage (P = 0.002), pathological N stage (P < 0.001), lymph node ratio (LNR) (P < 0.001), and operation type (P = 0.032) were significantly associated with overall survival. A multivariate analysis revealed that neo-adjuvant chemotherapy (P = 0.009), pathological T stage (P = 0.012), and LNR (P < 0.001) were independent prognostic factors. CONCLUSIONS Neo-adjuvant chemotherapy, pathological T stage, and LNR were independent prognostic factors for the overall survival of patients with stage III GC. The neo-adjuvant chemotherapy with oxaliplatin and S-1 can be used for the patients to improve their survival.
