Abstract
It is still controversial whether maternal anti-HBV antibodies (anti-HBVs) affect the infants' immune response to hepatitis B virus (HBV) vaccination. This multicentre study aims to address this question. First, we determined whether the transplacental transfer of maternal anti-HBVs occurs by measuring the titres of 90 anti-HBVs-positive pregnant women and their newborns. The anti-HBVs-positive rates of newborns ranged from 89.7% to 100.0%, depending on the maternal anti-HBVs titres. Secondly, we investigated the effects of maternal anti-HBVs on the immune response of infants to HBV vaccination. A total of 1063 mother-and-infant pairs were enrolled and divided into three groups with maternal anti-HBVs titres of <10 IU/L (negative - 37.9%), 10-499 and ≥500 IU/L. The infants' anti-HBVs-positive rate and titres were negatively correlated with maternal anti-HBVs titres: the anti-HBVs-positive rate of infants were 88.9% (360/405), 84.5% (381/451) and 77.3% (160/207) in mothers with low, intermediate and high antibody titres, respectively, P<.0001. Median titres of anti-HBVs (IU/L) among infants were 169.1, 141.0 and 79.4, respectively, P=.020. One hundred and sixty-two infants were negative for anti-HBVs after the standard vaccination, and 120 of 131 of these infants (91.6%) reached anti-HBVs positivity after the first "booster" dose. The maternal anti-HBVs titres did not significantly affect infant response to this booster. In summary, transplacental transfer of anti-HBVs occurs and high titres of maternal anti-HBVs may suppress the immune response of infants to the standard HBV vaccination. The current schedule of the 0, 1 and 6 month may not be the optimal choice of infants with anti-HBVs-positive mothers.

Abstract
Objective: To evaluate the specificity and limitations of sacroiliac joint magnetic resonance imaging (MRI) in the diagnosis of axial spondyloarthritis (SpA)in patients with chronic low back pain. Methods: We retrospectively analyzed clinical data of 390 patients with chronic low back pain in Department of Rheumatology, the PLA General Hospital from January 2013 to December 2015, including clinical manifestations, laboratory examinations and MRI data of sacroiliac joints. Results: There were 238 men and 152 women recruited. A total of 326 cases were diagnosed as axial SpA, including 216 men and 110 women with mean age (27.10±8.64) years and mean duration (7.64±3.50) months. Among these 326 patients, 243 (74.5%) were HLA-B27 positive. The other 64 patients were considered as diagnoses rather than SpA (non-SpA), consisting of 22 men and 42 women with mean age (31.29±7.76) years and mean duration (5.75±2.90)months. Non-SpA group had 10 (15.6%) patients with HLA-B27 positive. There were 68.1% and 65.0% SpA patients showing bone marrow edema and bone erosion of sacroiliac joint in MRI imaging respectively. Although there were 25.0% non-SpA patients with bone marrow edema and 7.8% with bone erosion in MRI of sacroiliac joint, the scores of bone marrow edema 0.00(0.00, 0.75) and bone erosion [0.00(0.00, 0.00)] were significantly lower compared with those in axial SpA group [bone marrow edema scores 2.00(0.00, 4.00), bone erosion scores 1.00(0.00, 3.00); P<0.05]. The scores of fat infiltration [1.00(0.00, 4.25), 1.00(0.00, 4.00)] and bone sclerosis [0.00(0.00, 1.00), 0.00(0.00, 1.75)] were not statistically different between two groups. Diagnostic sensitivity of bone marrow edema and bone erosion for axial SpA were 56.4% and 64.1% respectively, specificity were 93.8% and 92.2% respectively. The positive predictive value of bone marrow edema and bone erosion for axial SpA were 9.09 and 8.21, negative predictive value were 0.46 and 0.38.Diagnositic sensitivity of fatty infiltration and bone sclerosis for axial SpA group were 29.1% and 57.7%, specificity were 64.1% and 46.9%.The positive predictive value of fatty infiltration and bone sclerosis for axial SpA were 0.81 and 1.08, negative predictive value were 1.10 and 0.90. Conclusion: Sacroiliac joint MRI is a valuable method to diagnose axial SpA in patients with chronic low back pain. Yet it still has some limitations. Clinical presentations and spinal MRI would be helpful in some patients.

Abstract
Objective: To assess the value of different grading criteria of sacroiliac joint (SIJ) computed tomogrphy (CT) in ankylosing spondylitis (AS). Methods: Patients who had received SIJ CT examinations from June 2012 to December 2015 were enrolled.The CT scans were read by one rheumatologist.The difference between patients with sacroiliitis or without sacroiliitis was compared.The 1984 revision of modified New York (mNY) criteria, the criteria established by Lee (Lee criteria) and the Innsbruck criteria were used to evaluate SIJs on CT in patients with sacroiliitis. Results: Totally 2 714 patients were enrolled in this study.Thereinto 509 patients including 324 male and 185 female were detected with SIJs abnormality.The proportions of SIJs graded 3 or 4 by these three criteria were 79.37%, 82.91% and 76.32%, respectively.The consistency of grading between mNY criteria and Lee criteria was good (k=0.767, P<0.01). The correlation between Innsbruck criteria and other two criteria were satisfactory (r=0.866 and 0.839, respectively). There were more SIJs graded 3 by Lee criteria (64.44%), comparing with mNY criteria (60.90%). Forty five SIJs graded 1-3 by mNY criteria were graded 0 by Lee criteria, indicating that the latter criteria may have a better specificity. When evaluating the severity of SIJs, Innsbruck criteria has a better discrimination capability and the proportions of SIJs graded Ⅱ (A) to Ⅳ (B) were 10.71%, 8.94%, 26.82%, 20.92%, 10.12%, respectively. Conclusions: Lee criteria has a better diagnostic specificity with a reduction of difficulty in assessing procedure, while Innsbruck criteria is a more detailed grading system with a possibility to reflect the development of sacroiliitis.

Abstract
Recently, 5 amino acids were identified and verified as important metabolites highly associated with type 2 diabetes (T2D) development. This report aims to assess the association of tryptophan with the development of T2D and to evaluate its performance with existing amino acid markers. A total of 213 participants selected from a ten-year longitudinal Shanghai Diabetes Study (SHDS) were examined in two ways: 1) 51 subjects who developed diabetes and 162 individuals who remained metabolically healthy in 10 years; 2) the same 51 future diabetes and 23 strictly matched ones selected from the 162 healthy individuals. Baseline fasting serum tryptophan concentrations were quantitatively measured using ultra-performance liquid chromatography triple quadruple mass spectrometry. First, serum tryptophan level was found significantly higher in future T2D and was positively and independently associated with diabetes onset risk. Patients with higher tryptophan level tended to present higher degree of insulin resistance and secretion, triglyceride and blood pressure. Second, the prediction potential of tryptophan is non-inferior to the 5 existing amino acids. The predictive performance of the combined score improved after taking tryptophan into account. Our findings unveiled the potential of tryptophan as a new marker associated with diabetes risk in Chinese populations. The addition of tryptophan provided complementary value to the existing amino acid predictors.

Abstract
The IceCube neutrino telescope at the South Pole has measured the atmospheric muon neutrino spectrum as a function of zenith angle and energy in the approximate 320 GeV to 20 TeV range, to search for the oscillation signatures of light sterile neutrinos. No evidence for anomalous ν_{μ} or ν[over ¯]_{μ} disappearance is observed in either of two independently developed analyses, each using one year of atmospheric neutrino data. New exclusion limits are placed on the parameter space of the 3+1 model, in which muon antineutrinos experience a strong Mikheyev-Smirnov-Wolfenstein-resonant oscillation. The exclusion limits extend to sin^{2}2θ_{24}≤0.02 at Δm^{2}∼0.3 eV^{2} at the 90% confidence level. The allowed region from global analysis of appearance experiments, including LSND and MiniBooNE, is excluded at approximately the 99% confidence level for the global best-fit value of |U_{e4}|^{2}.

Abstract
Base on the clinical characteristics of septic arthritis in a group of systemic lupus erythematosus patients, this study has found out that high systemic lupus erythematosus disease activity index, leucopenia, high cumulative dose of glucocorticoid, methylprednisolone intravenous pulse therapy and joint cavity puncture were closely correlated with septic arthritis. Once septic arthritis is suspected, culture specimens should be collected and appropriate antibiotics are suggested immediately. Also, surgical drainage is a very useful approach.

Abstract
BACKGROUND In addition to obesity, low birth weight (LBW) has been proposed as another independent risk factor associated with cardiovascular disease and type 2 diabetes mellitus. OBJECTIVE This study aimed to evaluate the influence of birth weight on abdominal fat distribution, adipocytokine levels and associated metabolic alterations in obese children. METHODS A cross-sectional study was conducted in 92 children. Children were divided into three groups according to their body mass index and birth weight. Glucose and insulin (0 and 120 min), lipid profile and adipocytokines were measured. Abdominal fat distribution was assessed by magnetic resonance imaging. RESULTS Obese LBW children had higher fasting glucose (P = 0.054) and insulin (P < 0.001), and 120 min glucose (P < 0.001) and insulin levels (P < 0.001), such as increased HOMA-IR (homeostasis model assessment of insulin resistance index) (P < 0.001). Obesity and LBW were associated with lower concentrations of high molecular weight (HMW) adiponectin (-2.38 [IC 95% -4.27; -0.42, P = 0.018]) and higher subcutaneous adipose tissue (SAT) (28.05 [IC 95% 0.40; 55.7, P = 0.047]) compared with NBW obese children, independent of age or sex. CONCLUSIONS LBW in obese children is associated with lower HMW adiponectin, increased insulin resistance and greater SAT.

Abstract
Renal fibrosis is the common feature of chronic kidney disease and mainly mediated by TGFβ-associated pro-fibrogenic signaling, which causes excessive extracellular matrix accumulation and successive loss of kidney functions. Sinomenine (SIN), an alkaloid derived from medicinal herb extensively used in treatment of rheumatoid arthritis and various inflammatory disorders, displays renal protective properties in experimental animals; however its pharmacological potency against renal fibrosis is not explored. In this study we report that SIN possesses strong anti-renal fibrosis functions in kidney cell and in mouse fibrotic kidney. SIN beneficially modulated the pro-fibrogenic protein expression in TGFβ-treated kidney cells and attenuated the renal fibrotic pathogenesis incurred by unilateral ureteral obstruction (UUO), which correlated with its activation of Nrf2 signaling - the key defender against oxidative stress with anti-fibrotic potentials. Further investigation on its regulation of Nrf2 downstream events revealed that SIN significantly balanced oxidative stress via improving the expression and activity of anti-oxidant and detoxifying enzymes, and interrupted the pro-fibrogenic signaling of TGFβ/Smad and Wnt/β-catenin. Even more impressively SIN achieved its anti-fibrotic activities in an Nrf2-dependent manner, suggesting that SIN regulation of Nrf2-associated anti-fibrotic activities constitutes a critical component of SIN's renoprotective functions. Collectively our studies have demonstrated a novel anti-fibrotic property of SIN and its upstream events and provided a molecular basis for SIN's potential applications in treatment of renal fibrosis-associated kidney disorders.

Abstract
The objective of this study was to determine the effects of fast pH decline during the early postmortem period on calpain activity and the degradation of cytoskeletal proteins in broilers. Eighty broilers were randomly categorized into two groups: physical restraint (PR) and free struggle (FS). M. pectoralis major (PM) was used for determination of calpain activity, shear value, ultrastructure of myofibrils, and the degradation of desmin, titin, nebulin, and troponin-T. The pH (6.05) of FS group is significantly low than PR group (6.38) at 0.3 h postmortem. Fast pH decline during the early postmortem period led to a decrease of μ/m-calpain activities at 0.3 and 3 h postmortem (P < 0.05), but did not affect the ultimate μ/m-calpain activity. An initial fast decrease in pH increased the degradation of desmin, titin, nebulin, and increased the 30 kDa degradation fragments of troponin-T. Therefore, the fast pH decline during the early postmortem period decreased the μ/m-calpain activity and increased the degradation of cytoskeletal proteins in broiler muscle. It is possible that the fast pH decline experienced an earlier activation of calpains that resulted in earlier protein degradation and ultimately lower shear force.

Abstract
Dysregulated bile acids (BAs) are closely associated with liver diseases and attributed to altered gut microbiota. Here, we show that the intrahepatic retention of hydrophobic BAs including deoxycholate (DCA), taurocholate (TCA), taurochenodeoxycholate (TCDCA), and taurolithocholate (TLCA) were substantially increased in a streptozotocin and high fat diet (HFD) induced nonalcoholic steatohepatitis-hepatocellular carcinoma (NASH-HCC) mouse model. Additionally chronic HFD-fed mice spontaneously developed liver tumors with significantly increased hepatic BA levels. Enhancing intestinal excretion of hydrophobic BAs in the NASH-HCC model mice by a 2% cholestyramine feeding significantly prevented HCC development. The gut microbiota alterations were closely correlated with altered BA levels in liver and feces. HFD-induced inflammation inhibited key BA transporters, resulting in sustained increases in intrahepatic BA concentrations. Our study also showed a significantly increased cell proliferation in BA treated normal human hepatic cell lines and a down-regulated expression of tumor suppressor gene CEBPα in TCDCA treated HepG2 cell line, suggesting that several hydrophobic BAs may collaboratively promote liver carcinogenesis.

Abstract
OBJECTIVE To evaluate the clinical value of low-dose semicoronal computerized tomography (CT) of sacroiliac joints (SIJ) in the early diagnosis of ankylosing spondylitis (AS). METHODS Patients who were diagnosed with AS and had received axial CT examination of SIJs over the past 2 years were recruited. All of them simultaneously underwent a low-dose semicoronal CT of SIJs. The clinical data were recorded. Radiation dose was compared between low-dose CT and the previous conventional axial CT. Image quality of low-dose CT was assessed and correlation between image quality and weight or body mass index (BMI) was analyzed. CT images of the two groups were graded by modified New York criteria, the Lee criteria and the Innsbruck criteria. The kappa coefficient was used to assess the consistency of grading between the two groups. RESULTS Thirty-three patients were enrolled in this study. The effective dose (ED) of semicoronal SIJ CT was 3.37 mSv which was 49% lower than conventional axial CT (6.56 mSv). Lower dose had the potential protection of gonads. The quality of images in male patients with BMI<25 kg/m(2) and all female patients were good or excellent. There was a significant negative correlation between image quality and BMI (r=-0.746, P=0.000; r=-0.784, P=0.000; respectively). All patients were diagnosed as sacroiliitis by modified New York criteria and the grading of two groups was consistent. The consistency of grading between two groups was satisfactory no matter which classification criteria was used. (k=0.897 with Lee criteria; k=0.814 with Innsbruck criteria; P>0.05). CONCLUSIONS The radiation dose of semicoronal SIJ CT is significantly lower than that of the conventional axial CT with comparable efficacy of diagnosis.

Abstract
AIMS To assess the safety and pharmacokinetic and pharmacodynamic characteristics of BI 135585, a selective 11β-hydroxysteroid dehydrogenase-1 (11β-HSD1) inhibitor, after single- and repeated-dose administration. METHODS The single-dose study included open-label administration of 200 mg BI 135585 in healthy volunteers, while in the multiple-dose study, we carried out randomized, double-blind administration of 5-200 mg BI 135585 or placebo once daily over 14 days in patients with type 2 diabetes (T2DM). Assessments included 11β-HSD1 inhibition in the liver (urinary tetrahydrocortisol (THF)/tetrahydrocotisone (THE) ratio) and in subcutaneous adipose tissue (AT) ex vivo and determination of hypothalamus-pituitary-adrenal (HPA) axis hormone levels. RESULTS No major safety issues occurred with BI 135585 administration. The HPA axis was mildly activated with slightly increased, but still normal adrenocorticotropic hormone levels, increased total urinary corticoid excretion but unchanged plasma cortisol levels. After multiple doses of 5-200 mg BI 135585, exposure (area under the curve) increased dose-proportionally and half-life was 55-65 h. The urinary THF/THE ratio decreased, indicating liver 11β-HSD1 inhibition. Median 11β-HSD1 enzyme inhibition in the AT reached 90% after a single dose of BI 135585, but was low (31% or lower) after 14 days of continuous treatment. CONCLUSIONS BI 135585 was safe and well tolerated over 14 days and can be dosed once daily. Future studies are required to clarify the therapeutic potential of BI 135585 in view of its effects on 11β-HSD1 inhibition in AT after single and multiple doses. Enzyme inhibition in the AT was not adequately predicted by the urinary THF/THE ratio.

Abstract
Lung cancer, especially adenocarcinoma, is one of the leading causes of death in the world. Carcinoembryonic antigen (CEA), a superb non-small-cell lung cancer marker candidate, showed a beneficial effect in cancer therapy with oncolytic adenovirus in recent studies. Cancer-targeting dual gene-virotherapy delivers two therapeutic genes, linked by a connexon, in the replication-deficient vector instead of one gene so that they can work in common. In this study, we constructed a tumor-specific oncolytic adenovirus, CD55-TRAIL-IETD-MnSOD. The virus has the fusion protein complementary DNAs for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and for manganese superoxide dismutase (MnSOD) complementary DNA linked through a 4-amino acid caspase-8 cleavage site (IETD), and uses a CEA promoter to control virus E1A express. This is the first work to use a CEA promoter-regulated oncolytic adenovirus carrying two therapeutic genes for cancer research. Its targeting and anticancer capacity was evaluated by in vitro and in vivo experiments. The results indicated that CD55-TRAIL-IETD-MnSOD caused more cell apoptosis than CD55-TRAIL or CD55-MnSOD alone, or their combination in vitro, with low cytotoxicity of normal cells. In the A549 tumor xenograft model in nude mice, data showed that CD55-TRAIL-IETD-MnSOD could effectively suppress tumor growth than single gene groups, with no histological damage in liver, spleen or kidney tissues. Thus, the CEA-regulated dual-gene oncolytic virus CD55-TRAIL-IETD-MnSOD may be a novel potential therapy for lung cancer.

Abstract
Comprehensive and accurate characterization of brain metabolome is fundamental to brain science, but has been hindered by technical limitations. We profiled the brain metabolome in male Wistar rats at different ages (day 1 to week 111) using high-sensitivity and high-resolution mass spectrometry. Totally 380 metabolites were identified and 232 of them were quantitated. Compared with anatomical regions, age had a greater effect on variations in the brain metabolome. Lipids, fatty acids and amino acids accounted for the largest proportions of the brain metabolome, and their concentrations varied across the lifespan. The levels of polyunsaturated fatty acids were higher in infancy (week 1 to week 3) compared with later ages, and the ratio of omega-6 to omega-3 fatty acids increased in the aged brain (week 56 to week 111). Importantly, a panel of 20 bile acids were quantitatively measured, most of which have not previously been documented in the brain metabolome. This study extends the breadth of the mammalian brain metabolome as well as our knowledge of functional brain development, both of which are critically important to move the brain science forward.

Abstract
Recent metabonomic studies have identified an important role of bile acids in patients with liver cirrhosis. Serum bile acids, such as glycocholate (GCA), glycochenodeoxycholate (GCDCA), taurocholate (TCA), and taurochenodeoxycholate (TCDCA), increased significantly in liver cirrhosis patients. Our recently published urinary metabonomic study showed that glycocholate 3-glucuronide, taurohyocholate, TCA, glycolithocholate 3-sulfate, and glycoursodeoxycholate (GUDCA) were markedly increased in hepatitis B-induced cirrhotic patients (n = 63) compared with healthy controls (n = 31). The urinary levels of GUDCA were able to differentiate among three stages of cirrhotic patients with Child-Pugh (CP) score A, B, and C. In this study, we recruited two new cohorts of patients with hepatitis-B-induced cirrhosis and healthy control subjects and quantitatively profiled their serum bile acids using ultra-performance liquid chromatography triple quadrupole mass spectrometry. Serum bile acid profile and corresponding differential bile acids were characterized, in addition to the blood routine, liver, and renal function tests. The alterations of bile acids contributing to the intergroup variation between healthy controls and cirrhotic patients and among pathological stages of CP grade A, B and C were also investigated. Five bile acids, GCA, GCDCA, TCA, TCDCA, and GUDCA, were significantly altered among different stages of liver cirrhosis (n = 85), which was validated with an independent cohort of cirrhotic patients (n = 53). Our results show that dynamic alteration of serum bile acids is indicative of an exacerbated liver function, highlighting their potential as biomarkers for staging the liver cirrhosis and monitoring its progression.

Abstract
OBJECTIVE To evaluate the clinical value of Short Form-36 (SF-36) questionnaire and the most commonly used clinical measures in a prospective cohort study of ankylosing spondylitis (AS) patients. METHODS A total of 517 AS patients were collected from the Department of Rheumatology, Chinese PLA General Hospital from August 2013 to September 2015. The Quality of Life (QoL) was assessed by SF-36 questionnaire and compared with the general population. The correlations between QoL and clinical measures of AS, including the Bath AS disease activity index (BASDAI), Bath AS functional index (BASFI), Bath AS metrology index (BASMI) et al, were analyzed. RESULTS BASDAI and BASFI were significantly correlated with SF-36 scores (r>0.3, P<0.01). Logistic multiple regression analysis showed that BASDAI, BASFI, BASMI and education had close correlation with the baseline global QoL, physical and mental health. Among these clinical measures, BASDAI variation showed the most important influence on the change of global QoL, physical health and mental health (OR=0.235, 0.209, 0.125; P<0.01). CONCLUSIONS SF-36 can objectively reflect the QoL of patients with AS. Clinical measures such as BASDAI and BASFI show great application value in this prospective cohort study of AS patients.

Abstract
Sinomenine is originally derived from medicinal herb and used preferentially in treatment of rheumatoid diseases in Far East regions. SIN has strong anti-inflammatory and immune-regulatory properties, acting mainly through inhibiting NF-kB signaling. Although the upstream target through which SIN affects NF-kB activity is unknown, evidence suggests that SIN might regulate inflammation through Nrf2 signaling. In this study we explored the role of Nrf2 in mediating SIN's anti-inflammation and kidney protection in a mouse model of obstructive nephropathy. We found that SIN is an activator of Nrf2 signaling. It markedly increased Nrf2 protein level, Nrf2 nuclear translocation, Nef2 transcription capacity, and the downstream protein expression. We further demonstrated that SIN activation of Nrf2 is likely due to its repression of the Nrf2 inhibitor Keap1 since it drastically reduced Keap1 protein through the PKC-sensitive ubiquitination-proteasomal degradation. SIN treatment of nephropathy mice effectively reduced the kidney damage and inflammatory responses, balanced renal oxidative stress, and improved the pathological protein expression in an Nrf2 dependent manner. In addition, SIN also Nrf2-dependently modulated macrophage M1/M2 polarization and inhibited the IkBα phosphorylation and NF-kB nuclear translocation, hence revealing an important upstream event that contributed to its anti-inflammation and tissue protection. Taken together our study has identified a novel pathway through which SIN exerts its anti-inflammation and renal protective functions, and provided a molecular basis for SIN potential applications in the treatment of kidney and other inflammatory disorders.

Abstract
We studied four Chinese families with pure hereditary spastic paraplegia (HSP) to investigate the clinical features and associated genetic mutations. Linkage analysis was performed for all families to map the disease locus onto autosomal chromosomes, and related loci involved in HSP on the X chromosome were also examined. Polymerase chain reaction (PCR) sequencing was used to detect gene mutations. To confirm the influence of a splice-site mutation on mRNA, we used reverse transcription-PCR and direct sequencing. Linkage analysis and ATL1 gene sequencing of amniocytes were performed for prenatal genetic diagnosis. One missense variant (c.1517T>A) and a splice-site mutation (c.1245+1G>A) in SPAST, and two missense variants (c.715C>T, c.1204T>G) in ATL1 were identified. The c.1245+1G>A mutation caused a deletion of exon 9 in the SPAST gene. Prenatal genetic diagnosis showed that fetus did not carry the ALT1 c.1204T>G mutation. Follow-up was maintained for 5 years, and the negative result was confirmed by evidence of a healthy growing boy. We identified two novel mutations and two previously reported mutations in SPAST and ATL1, respectively. The family with the ATL1 c.1204T>G mutation exhibited male-lethality, female infancy-onset, and pseudo- X-linked dominant transmission, which had never been previously reported for HSP. Characteristic facial features were also noticed. The boy on whom prenatal gene diagnosis was performed is healthy and without unusual facies, suggesting that the c.1204T>G mutation might be related to these features. The results extend the genetic spectrum of HSP and suggest that linkage analysis remains a powerful tool in gene discovery studies.

Abstract
The aim of this study was to observe the influence of gap junction (GJ) functional changes on the hepatotoxicity of TNF-α. Three different methods were employed to study functional effects of the GJ inhibition: 1) pretreatment with a GJ inhibitor; 2) inoculation of cells at high and low densities; and 3) inhibition of the expression of connexin 32 (Cx32) by small inhibitory RNA transfection. We then observed the influence of these treatments on hepatotoxicity following treatment with different concentrations of TNF-α for various duration. The hepatotoxicity of TNF-α was observed to occur in a dose- and time-dependent manner; after pretreatment inhibition, the hepatotoxicity of TNF-α was significantly reduced (P < 0.01). The hepatotoxicity of TNF-α was also found to be remarkably lower in cells that had been inoculated at low density (as measured by the amount of GJ formation among cells) than in those inoculated at density (P < 0.01). In addition, following Cx32 inhibition, the hepatotoxicity of TNF-α was significantly decreased (P < 0.01) as well. Together, these results suggest that inhibition of GJ function or of its component Cx32 significantly decreases the hepatotoxicity of TNF-α, and that the expression of Cx32 plays an important role in the hepatotoxicity of TNF-α.

Abstract
Results from the IceCube Neutrino Observatory have recently provided compelling evidence for the existence of a high energy astrophysical neutrino flux utilizing a dominantly Southern Hemisphere data set consisting primarily of ν(e) and ν(τ) charged-current and neutral-current (cascade) neutrino interactions. In the analysis presented here, a data sample of approximately 35,000 muon neutrinos from the Northern sky is extracted from data taken during 659.5 days of live time recorded between May 2010 and May 2012. While this sample is composed primarily of neutrinos produced by cosmic ray interactions in Earth's atmosphere, the highest energy events are inconsistent with a hypothesis of solely terrestrial origin at 3.7σ significance. These neutrinos can, however, be explained by an astrophysical flux per neutrino flavor at a level of Φ(E(ν))=9.9(-3.4)(+3.9)×10(-19) GeV(-1) cm(-2) sr(-1) s(-1)(E(ν)/100 TeV(-2), consistent with IceCube's Southern-Hemisphere-dominated result. Additionally, a fit for an astrophysical flux with an arbitrary spectral index is performed. We find a spectral index of 2.2(-0.2)(+0.2), which is also in good agreement with the Southern Hemisphere result.

Abstract
The origin of rhabdomyosarcoma (RMS) remains controversial. However, specific microRNAs (miRNAs) are downregulated in RMS and it is possible that re-expression of these miRNAs may lead to differentiation. Transforming growth factor-β1 (TGF-β1) is known to block differentiation of RMS. We therefore analyzed miRNA microarrays of RMS cell lines with or without TGF-β1 knockdown and identified a novel anti-oncogene miR-411-5p. Re-expression of miR-411-5p inhibited RMS cell proliferation in vitro and tumorigenicity in vivo. Using a luciferase reporting system and sequence analysis, the potential target of miR-411-5p was identified as sprouty homolog 4 (SPRY4), which inhibits protein kinase Cα-mediated activation of mitogen-activated protein kinases (MAPKs), especially p38MAPK phosphorylation. These results revealed an inverse correlation between TGF-β1/SPRY4 and miR-411-5p levels. SPRY4 small interfering RNA and miR-411-5p both activated p38MAPK phosphorylation and also promoted apoptosis and myogenic differentiation, indicated by increased caspase-3, myosin heavy chain, and myosin expression. SPRY4 and miR-411 mRNA levels correlated with TGF-β1 expression levels in RMS tissues, which was confirmed by immunohistochemical staining for TGF-β1, SPRY4, and phosphorylated p38MAPK proteins. Overall, these results indicate that miR-411-5p acts as an RMS differentiation-inducing miRNA prompting p38MAPK activation via directly downregulating SPRY4. These results establish an autoregulatory loop between TGF-β1/miR-411-5p/SPRY4 and MAPK in RMS, which governs the switch between proliferation and differentiation.

Abstract
Diabetes and hypertension have been associated with cardiovascular diseases and stroke. Some reports have related the coexistence of hypertension and diabetes with increase in the risk of developing vascular complications. Recently some studies have shown results suggesting that in the early stages of diabetes and hypertension exist a reduced functional response to vasopressor agents like angiotensin II (Ang II), which plays an important role in blood pressure regulation mechanism through the activation of its AT1 and AT2 receptors. For that reason, the aim of this work was to study the gene and protein expression of AT1 and AT2 receptors in aorta of diabetic SHR and WKY rats. Diabetes was induced by the administration of streptozotocin (60 mg/kg i.p.). After 4 weeks of the onset of diabetes, the protein expression was obtained by western blot and the mRNA expression by RT-PCR. Our results showed that the hypertensive rats have a higher mRNA and protein expression of AT1 receptors than normotensive rats while the AT2 expression remained unchanged. On the other hand, the combination of diabetes and hypertension increased the mRNA and protein expression of AT1 and AT2 receptors significantly. In conclusion, our results suggest that diabetes with hypertension modifies the mRNA and protein expression of AT1 and AT2 receptors. However, the overexpression of AT2 could be associated with the reduction in the response to Ang II in the early stage of diabetes.

Abstract
Rabies remains an enigmatic and widely discussed global infectious disease and causes an increasing number of deaths. The currently used highly effective prophylactic and post exposure (p.e.) vaccination depends solely upon inexpensive, effective and safe vaccines to counteract the spread of the disease. In this study, the potential of an attenuated Chinese rabies vaccine (SRV9) strain in prophylactic and p.e. vaccination against the street strain of rabies virus (RV) was evaluated in mice. Prophylactic vaccination consisting of one intramuscular (i.m.) dose of SRV9 protected 100% of mice from intracerebral (i.c.) challenge with a lethal dose of the street virus. The latter was detected in the brain of mice at day 6 post challenge by RT-PCR. Post exposure vaccination was performed at days 1, 2, 3, 4, 5 and 6 post infection (p.i.) with either SRV9 or inactivated rabies vaccine. The survival rates after i.m. inoculation of SRV9 at the indicated days were 70%, 50%, 30%, 20%, 10%, and 0%, respectively; the corresponding survival rates for the inactivated rabies vaccine were 30%, 20%, 10%, 0%, 0%, and 0%, respectively. However, 100%, 90%, 70%, 50%, 20%, 10%, and 10% of mice survived after i.c. inoculation of SRV9 at the indicated days. The increased permeability of the blood-brain barrier and the infiltration of CD19+ B cells into the central nervous system after i.c. inoculation of SRV9 are regarded as prerequisites for the clearance of the street virus. The obtained data suggest that SRV9 is a promising candidate for prophylactic and p.e. vaccination against rabies infection and that it exhibits a potential for the control of rabies in China.

Abstract
BACKGROUND MicroRNAs (miRNAs) have emerged as epigenetic regulators of metabolism and energy homeostasis. There is a growing body of evidence pointing to miRNAs that have important regulatory roles in insulin sensitivity. OBJECTIVE The aim of this work was to explore the expression and mechanism of action of miR-26b in obesity-related insulin resistance (IR) in adipocytes. METHODS Quantitative real-time PCR was performed to determine miR-26b expression in obese rodent models, human obesity subjects and insulin-resistant adipocytes. We analysed the roles of miR-26b overexpression and inhibition on glucose uptake in adipocytes. Western blotting was used to detect the levels of protein molecules involved in the phosphoinositide-3-kinase (PI3K) pathway. Bioinformatics and the Dual Luciferase Assay were used to identify the target gene of miR-26b. We assessed the regulatory roles of miR-26b on the phosphatase and tensin homologue (PTEN)/PI3K/AKT pathway and the relationship between miR-26b and the metabolism of human obese subjects. RESULTS Levels of miR-26b are reduced in visceral adipose tissue (VAT) in obese rodent models, human obesity and insulin-resistant adipocytes. MiR-26b promotes insulin-stimulated glucose uptake and increases insulin-stimulated glucose transporter type 4 translocation to the plasma membrane in human mature adipocytes. MiR-26b modulates insulin-stimulated AKT activation via inhibition of its target gene, PTEN, and significantly increases insulin sensitivity via the PTEN/PI3K/AKT pathway. The expression level of miR-26b negatively correlates with increasing body mass index and homeostasis model assessment for IR in human obese subjects. CONCLUSION Decreased miR-26b expression in VAT may be involved in obesity-related IR by interrupting the PTEN/PI3K/AKT pathway.

Abstract
We examined the expression of peripheral blood natural killer T (NKT) cells in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients and predicted its efficacy after pegylated interferon α-2a (Peg-INFα-2a) therapy. Sixty-three cases of HbeAg-positive CHB inpatients and outpatients, treated in the Third Xiangya Hospital of Central South University from January to December 2010, were administrated Peg-INFα-2a 18 myriad international unit intramuscularly once per week for 48 weeks. The number of peripheral NKT cells, 5 quantitative indicators of hepatitis B, and hepatitis B virus DNA capacity were detected at each time point. Forty-eight weeks after Peg-INFα-2a treatment, 26 HBeAg-positive CHB patients exhibited significant effects, 21 cases exhibited effects, and 16 cases showed no effects. The ratio of peripheral blood NKT cells in T lymphocytes before and 4, 8, and 12 weeks after treatment in the significant effect group was significantly increased compared to the effect group and no effect group (P < 0.01); at the 48th week of treatment and 24 weeks after the drug was withdrawn, NKT cell expression in the significant effect group was significantly higher than that in the effect group (t = 32.0, P < 0.01; t = 27.6, P < 0.01, respectively). A total of 27 patients showed HBeAg seroconversion until the 24th week after drug withdrawal. During treatment with Peg-INFα-2a in HBeAg-positive CHB patients, expression of peripheral blood NKT cells could be used to predict efficacy.

Abstract
A diffuse flux of astrophysical neutrinos above 100 TeV has been observed at the IceCube Neutrino Observatory. Here we extend this analysis to probe the astrophysical flux down to 35 TeV and analyze its flavor composition by classifying events as showers or tracks. Taking advantage of lower atmospheric backgrounds for showerlike events, we obtain a shower-biased sample containing 129 showers and 8 tracks collected in three years from 2010 to 2013. We demonstrate consistency with the (fe:fμ:fτ)⊕≈(1:1:1)⊕ flavor ratio at Earth commonly expected from the averaged oscillations of neutrinos produced by pion decay in distant astrophysical sources. Limits are placed on nonstandard flavor compositions that cannot be produced by averaged neutrino oscillations but could arise in exotic physics scenarios. A maximally tracklike composition of (0:1:0)⊕ is excluded at 3.3σ, and a purely showerlike composition of (1:0:0)⊕ is excluded at 2.3σ.

Abstract
Genome-wide gene expression measurements have enabled comprehensive studies that integrate the changes of gene expression and phenotypic information to uncover their novel associations. Here we reported the association analysis between psychophysical phenotypes and genome-wide gene expression changes in human adaptation to one of the most extreme climates on Earth, the Antarctic Dome Argus. Dome A is the highest ice feature in Antarctica, and may be the coldest, driest and windiest location on earth. It is considered unapproachable due to its hostile environment. In 2007, a Chinese team of 17 male explorers made the expedition to Dome A for scientific investigation. Overall, 133 psychophysical phenotypes were recorded, and genome-wide gene expression profiles from the blood samples of the explorers were measured before their departure and upon their arrival at Dome A. We found that mood disturbances, including tension (anxiety), depression, anger and fatigue, had a strong, positive, linear relationship with the level of a male sex hormone, testosterone, using the Pearson correlation coefficient (PCC) analysis. We also demonstrated that significantly lowest-level Gene Ontology groups in changes of gene expression in blood cells with erythrocyte removal were consistent with the adaptation of the psychophysical characteristics. Interestingly, we discovered a list of genes that were strongly related to significant phenotypes using phenotype and gene expression PCC analysis. Importantly, among the 70 genes that were identified, most were significantly related to mood disturbances, where 42 genes have been reported in the literature mining, suggesting that the other 28 genes were likely novel genes involved in the mood disturbance mechanism. Taken together, our association analysis provides a reliable method to uncover novel genes and mechanisms related to phenotypes, although further studies are needed.

Abstract
Propofol is a short-acting intravenous anaesthetic agent and widely used not only in operating rooms but also in the intensive care unit (ICU). Apart from its multiple anaesthetic advantages, the neuroprotective effect of propofol has been demonstrated in diverse models of neuronal injury. The effect of propofol results from activation of gamma-aminobutyric acid (GABA) receptor, modulation excitatory amino acid transmitter system and protecting brain cells against oxidative stress. Moreover, propofol is able to supress apoptosis and inflammation and to regulate neuroprotection-associated proteins or ion homeostasis to act its neuroprotective effects. This review focuses on the research progress of the neuroprotective effects of propofol and its mechanisms of action to date. The implications for possible use for the clinical setting are also discussed.
