Abstract
Infectious diseases remain the world's top contributors to death and disability, and, with recent outbreaks of Zika virus infections there has been an urgency for simple, sensitive and easily translatable point-of-care tests. Here we demonstrate a novel point-of-care platform to diagnose infectious diseases from whole blood samples. A microfluidic platform performs minimal sample processing in a user-friendly diagnostics card followed by real-time reverse-transcription loop-mediated isothermal amplification (RT-LAMP) on the same card with pre-dried primers specific to viral targets. Our point-of-care platform uses a commercial smartphone to acquire real-time images of the amplification reaction and displays a visual read-out of the assay. We apply this system to detect closely related Zika, Dengue (types 1 and 3) and Chikungunya virus infections from whole blood on the same pre-printed chip with high specificity and clinically relevant sensitivity. Limit of detection of 1.56e5 PFU/mL of Zika virus from whole blood was achieved through our platform. With the ability to quantitate the target nucleic acid, this platform can also perform point-of-care patient surveillance for pathogen load or select biomarkers in whole blood.

Abstract
A simple and robust technique for directly measuring the loop gain and bandwidth of a phase-locked loop (PLL) is proposed. This technique can be used for the real-time measurement of the real loop gain in a closed PLL without breaking its locking state. The agreement of the measured loop gain and theoretical calculations proves the validity of the proposed measurement technique. This technique with a simple configuration can be easily expanded to other phase-locking systems whose loop gain and bandwidth should be measured precisely.

Abstract
Recently we elucidated that tobacco TTG2 cooperates with ARF8 to regulate the vegetative growth and seed production. Here we show that TTG2 and ARF8 control flower colouring by regulating expression of ANS and DFR genes, which function in anthocyanin biosynthesis. Genetic modifications that substantially altered expression levels of the TTG2 gene and production quantities of TTG2 protein were correlated with flower development and colouring. Degrees of flower colour were increased by TTG2 overexpression but decreased through TTG2 silencing, in coincidence with high and low concentrations of anthocyanins in flowers. Of five genes involved in the anthocyanin biosynthesis pathway, only ANS and DFR were TTG2-regulated and displayed enhancement and diminution of expression with TTG2 overexpression and silencing, respectively. The floral expression of ANS and DFR also needed a functional ARF8 gene, as ANS and DFR expression were attenuated by ARF8 silencing, which concomitantly diminished the role of TTG2 in anthocyanin production. While ARF8 required TTG2 to be expressed by itself and to regulate ANS and DFR expression, the concurrent presence of normally functional TTG2 and ARF8 was critical for floral production of anthocyanins and also for flower colouration. Our data suggest that TTG2 functions concomitantly with ARF8 to control degrees of flower colour by regulating expression of ANS and DFR, which are involved in the anthocyanin biosynthesis pathway. ARF8 depends on TTG2 to regulate floral expression of ANS and DFR with positive effects on anthocyanin production and flower colour.

Abstract
AIMS When a fixed activity of radioiodine is given for differentiated thyroid cancer (DTC), absorbed doses of radioiodine can vary widely and are not usually measured. Leeds Cancer Centre has routinely used a form of lesion-specific dosimetry for radioiodine patients. This study investigated if the results of dosimetry influenced treatment decisions for patients with advanced DTC. MATERIALS AND METHODS Since 2005, patients with regionally advanced/metastatic DTC, who underwent radioiodine treatment together with dosimetry, were included in this study. Patients were excluded if their radioiodine post-treatment scan showed no abnormal uptake. Dosimetry was calculated using images taken 2, 3 and 7 days post-radioiodine. Regions of interest were drawn around lesions that required dosimetry and a time-dose activity curve was created. The total cumulative activity was equal to the area under the curve. Each patient's results were prospectively assessed by their oncologist regarding the usefulness of dosimetry in making management decisions. RESULTS Thirty patients were studied and underwent 102 admissions of radioiodine between them. Dosimetry was carried out during 83 of 102 admissions. An absorbed dose of >20 Gy was taken as significant from dosimetry calculations, following which further radioiodine was considered. In 80% of patients, dosimetry was found to be useful when making treatment decisions. Only on 1/19 admissions did dosimetry calculate a minimum dose above 20 Gy in patients who had a total of four or more admissions for radioiodine. Ten per cent (3/30) had a complete response to radioiodine, both biochemically and radiologically, with a median follow-up of 6.7 months. Thirty-three per cent had a partial response/stable disease to radioiodine. The remainder had progressive disease. The decision to discontinue radioiodine therapy was often based on dosimetry and thyroglobulin results. Dosimetry was very useful for patients with thyroglobulin antibodies. CONCLUSION Only 10% had a complete response. Therefore, a significant number of patients became refractory to radioiodine during a course of repeat admissions for treatment. Dosimetry (often together with thyroglobulin and anatomical scans) helped to identify these patients to avoid further futile radioiodine therapy.

Abstract
OBJECTIVE To explore the relationship between Type 2 diabetes and primary liver cancer. MATERIALS AND METHODS In the period from December 2008 to December 2014, all blood sugar data of patients in our hospital was collected, and the total number is 18213. Except for repeatedly hospitalized diabetic person, newborn stress status, or venous transfusion blood glucose, gestational diabetes, etc., By retrieving the medical record information of patients in the hospital, and using telephone or letter follow-up the patients, we collected 127 people with type 1 diabetes and found no liver cancer patients; Type 2 diabetes, 10,794 cases of patient information, 59 with primary liver cancer. For data analysis, Stata11.0 ratio was used as the main analysis indicators, using Chi-square test and statistical analysis. RESULTS About 10,794 Type 2 diabetes cases with 59 primary liver cancer, the incidence is 54.66/10,000, men liver cancer incidence (92.78/10,000) than women (27.13/10,000), with significant difference (χ2 = 26.621, P < 0.001). As the growth of the age, the possibility of liver cancer in patients with diabetes increased significantly (χ2 = 19.961, P = 0.001). The rate was highest for 50-60-year-old men, and the women at age 70, and older incidence is highest. Irrespective of men or women with diabetes as the growth of the age, the possibility of liver cancer had significantly increased (P = 0.001, P = 0.002). Hepatitis B or hepatitis C incidence was 2.94%, but diabetes incidence of hepatitis men (3.98%) and women (2.01%) did not find significant differences (χ2 = 0.3361, P = 0.562). Three hundred and seventeen cases of Type 2 diabetes with hepatitis, the incidence of primary liver cancer was 11.67%, the liver cancer incidence of diabetes patients with hepatitis men (17.78%) than women (3.97%), with significant difference (χ2 = 37.429, P < 0.001). With the growth of age, the overall risk of getting liver cancer (χ2 =15.023, P = 0.01) of diabetes and hepatitis patients is significantly increased, and with the growth of age, the risk of getting liver cancer of male patients showed significant (P < 0.05), but not the female patients. Without merge hepatitis, the morbility of primary liver cancer in 10477 cases of type2 diabetes incidence is 0.21%, the liver cancer incidence men (0.34%) than women (0.11%), with significant difference (χ2 = 6.471, P = 0.011).As the growth of age, the overall risk of getting liver cancer of diabetes patients without hepatits is significantly increased (χ2 =15.612, P = 0.008) ,and the risk of getting liver cancer of male patients showed significant (P < 0.05) as the growth of the age, but not the female patients. Diabetic persons according to the illness time can be divided into 0-5 years, 5-10 years, 10-20 years, and over 20 years of four stages, including 5-10 years and 10-20 years is liver cancer patients with diabetes incidence peak, male diabetic hepatitis in patients with liver cancer incidence than women, with significant difference (χ2 = 22.757, P < 0.001). The possibility of liver cancer in patients with diabetes increased significantly (χ2 = 15.023, P = 0.01) for longer duration of illness, but only the male patients with liver cancer incidence showed significant difference with longer duration of illness, women showed no significance. CONCLUSION Diabetes was associated with the primary liver cancer, most likely is one of the causes of primary liver cancer.

Abstract
Recently, theoretical studies show that layered HfTe5 is at the boundary of weak & strong topological insulator (TI) and might crossover to a Dirac semimetal state by changing lattice parameters. The topological properties of 3D stacked HfTe5 are expected hence to be sensitive to pressures tuning. Here, we report pressure induced phase evolution in both electronic & crystal structures for HfTe5 with a culmination of pressure induced superconductivity. Our experiments indicated that the temperature for anomaly resistance peak (Tp) due to Lifshitz transition decreases first before climbs up to a maximum with pressure while the Tp minimum corresponds to the transition from a weak TI to strong TI. The HfTe5 crystal becomes superconductive above ~5.5 GPa where the Tp reaches maximum. The highest superconducting transition temperature (Tc) around 5 K was achieved at 20 GPa. Crystal structure studies indicate that HfTe5 transforms from a Cmcm phase across a monoclinic C2/m phase then to a P-1 phase with increasing pressure. Based on transport, structure studies a comprehensive phase diagram of HfTe5 is constructed as function of pressure. The work provides valuable experimental insights into the evolution on how to proceed from a weak TI precursor across a strong TI to superconductors.

Abstract
OBJECTIVES To determine the interrelationships between baseline Mini-Mental State Examination (MMSE) score and overall long-term risk of cerebrovascular disease (CBVD). MATERIALS & METHODS This was a prospective cohort study of subjects aged 55 years or more who were enrolled in the Beijing Longitudinal Study of Aging (BLSA) and had a baseline MMSE score available. Baseline MMSE score was divided into four categories: ≥28, 26-27, 23-25, and ≤22. Participants were followed for 23 years. Cox regression models were used to examine the association between MMSE score and CBVD. RESULTS A total of 2101 participants were included in this analysis, 335 (15.9%) with an MMSE score ≥28, 365 (17.4%) with a score of 26-27, 579 (27.6%) with a score of 23-25, and 822 (7.4%) with a score ≤22. There were 576 cases of CBVD. The overall risk of CBVD increased with decreasing MMSE score. The impact of MMSE score on the risk of CBVD was much stronger in women than in men. The hazard ratio for CBVD risk was 1.76 (95% confidence interval [CI], 1.29-2.39, P < 0.05) for subjects with an MMSE score ≤22, and 1.21 (95% CI, 0.91-1.61, P < 0.05) for those with an MMSE score of 23-25. Higher MMSE scores were less strongly associated with the risk of CBVD. CONCLUSIONS Elderly people with lower MMSE scores, especially women, are at higher long-term risk of CBVD.

Abstract
The pharmacokinetic characteristics of valnemulin in layer chickens were studied after single intravenous, intramuscular, and oral administration at a dose of 15 mg/kg body weight. Plasma samples at certain time points were collected and the drug concentrations in them by ultra high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS). The concentration-time data for each individual were plotted by noncompartmental analysis for the whole three routes. Following intravenous administration, the plasma concentration showed tiny fluctuation. The elimination half-life (T1/2λz), total body clearance (Cl), and area under the plasma concentration-time curve (AUC) were 1.85 ± 0.43 h, 2.2 ± 0.9 L/h, and 7.52 ± 2.46 μg·h/mL, respectively. Following intramuscular administration, the peak concentration (Cmax , 1.40 ± 0.43 μg/mL) was achieved at the time of 0.34 h. A multiple-peak phenomenon existed after oral administration, and the first peak and secondary peak were at 10 min and during 2-4 h, respectively, while the tertiary peak appeared during 5-15 h. The bioavailability (F %) for intramuscular and oral administration was 68.60% and 52.64%, respectively. In present study, the detailed pharmacokinetic profiles showed that this drug is widely distributed and rapidly eliminated, however has a low bioavailability, indicating that valnemulin is likely to be a favorable choice in the clinical practice.

Abstract
Abstract
Estrogen receptor positive (ER+) breast cancer accounts for 70% of all breast cancers and is primarily treated with endocrine therapy. Approximately 40% of patients on endocrine therapy will become resistant via a number of mechanisms. There is evidence that in many cases ER continues to play a central role, including mutations in ER leading to a constitutively active receptor. Estrogen receptor degraders like fulvestrant are effective in shutting down ER signaling; however, poor pharmaceutical properties limit fulvestrant clinical activity and prevent it from achieving maximum receptor blockade.
We describe the discovery of SAR439859, a novel, orally bioavailable SERD that is a potent antagonist and degrader of ER both in vitro and in vivo. SAR439859 has robust activity in multiple ER+ breast cancer cell lines including cells that are resistant to tamoxifen as well as cell lines harboring ER mutants. Across a large panel of ER+ cells, SAR439859 demonstrated broad and superior ER degradation activity than most SERDs undergoing clinical testing. This leads to a profound inhibition of ER signaling, better inhibition of cell growth and results in improved in vivo efficacy. SAR439859 demonstrated tumor regression in all ER+ BC models including MCF7-ESR1 mutant-Y537S model, as well as patient-derived xenograft model that is resistant to endocrine therapies. Furthermore, SAR439859 displays limited cross-resistance with other class of SERDs.
Taken together, these results suggest that SAR439859 would be of therapeutic benefit in metastatic BC setting for patients harboring wild type or mutant ER. SAR439859 is being advanced toward the clinic.

Abstract
Suberoylanilide hydroxamic acid (SAHA) exerts marked anticancer effects via promotion of apoptosis, cell cycle arrest, and prevention of oncogene expression. In this study, serum metabolomics and artificial intelligence recognition were used to investigate SAHA toxicity. Forty rats (220 ± 20 g) were randomly divided into control and three SAHA groups (low, medium, and high); the experimental groups were treated with 12.3, 24.5, or 49.0 mg kg-1 SAHA once a day via intragastric administration. After 7 days, blood samples from the four groups were collected and analyzed by gas chromatography-mass spectrometry, and pathological changes in the liver were examined using microscopy. The results showed that increased levels of urea, oleic acid, and glutaconic acid were the most significant indicators of toxicity. Octadecanoic acid, pentadecanoic acid, glycerol, propanoic acid, and uric acid levels were lower in the high SAHA group. Microscopic observation revealed no obvious damage to the liver. Based on these data, a support vector machine (SVM) discrimination model was established that recognized the metabolic changes in the three SAHA groups and the control group with 100% accuracy. In conclusion, the main toxicity caused by SAHA was due to excessive metabolism of saturated fatty acids, which could be recognized by an SVM model.

Abstract
OBJECTIVES To explore the attitudes of primary healthcare workers, including township public health workers (TPHWs) and village doctors (ViDs), towards web-based training on basic public health services (BPHS) and to examine the factors influencing their attitudes. STUDY DESIGN Cross-sectional study. METHODS Questionnaires addressing training status, needs, and attitudes towards web-based public health training were administered to 2768 primary healthcare workers from May to September 2013. Multivariate logistic regression models were used to identify the factors that were significantly associated with a positive attitude towards web-based public health training. RESULTS Among the 2768 participants, 90.6% of the TPHWs and 86.9% of the ViDs expressed a positive attitude towards web-based BPHS training. TPHWs who had a positive attitude towards previous public health training (odds ratio [OR] = 2.75, 95% confidence interval [CI] = 1.28-5.93) and better computer skills (OR = 2.59, 95% CI = 1.03-6.48) were more likely to adopt web-based training on BPHS, as were ViDs who had better computer skills (OR = 2.54, 95% CI = 1.58-4.11) and better Internet speeds (neutral: OR = 2.81, 95% CI = 1.58-5.01; satisfied: OR = 2.53, 95% CI = 1.28-5.01). TPHWs who tended to read papers (OR = 0.24, 95% CI = 0.11-0.50) and were aged 50 years or older (OR = 0.34, 95% CI = 0.14-0.87), as were ViDs who tended to read papers (OR = 0.48, 95% CI = 0.29-0.77), expressed a more negative attitude towards web-based BPHS training. CONCLUSIONS The findings indicated that most primary healthcare workers have a positive attitude towards web-based BPHS training. More priority measures, such as conducting computer training, improving Internet quality and integrating mobile technology, are recommended and will further improve the implementation of web-based public health training programs.

Abstract
We previously demonstrated that fermitin family member 1 (FERMT1) was significantly overexpressed in colon cancer (CC) and associated with poor metastasis-free survival. This study aimed to investigate the precise role of FERMT1 in CC metastasis and the mechanism by which FERMT1 is involved in the epithelial-mesenchymal transition (EMT). Correlations between FERMT1 and EMT markers (E-cadherin, Slug, N-cadherin and β-catenin) were examined via immunohistochemistry in a cohort of CC tissues and adjacent normal colon mucosae. A series of in vitro and in vivo assays were performed to elucidate the function of FERMT1 in CC metastasis and underlying mechanisms. The upregulated expression of FERMT1 in CC tissues correlated positively with that of Slug, N-cadherin and β-catenin, but correlated inversely with E-cadherin expression. Altered FERMT1 expression led to marked changes in the proliferation, migration, invasion and EMT markers of CC cells both in vitro and in vivo. Investigations of underlying mechanisms found that FERMT1 interacted directly with β-catenin and activated the Wnt/β-catenin signaling pathway by decreasing the phosphorylation level of β-catenin, enhancing β-catenin nuclear translocation and increasing the transcriptional activity of β-catenin/TCF/LEF. Activation of the Wnt/β-catenin pathway by CHIR99021 reversed the effect of FERMT1 knockdown, whereas inhibition of the Wnt/β-catenin pathway by XAV939 impaired the effect of FERMT1 overexpression on EMT and cell motility. In conclusion, findings of this study suggest that FERMT1 activates the β-catenin transcriptional activity to promote EMT in CC metastasis.

Abstract
OBJECTIVE To investigate the occlusal force distribution and the characteristics of the occlusion time of patients with All-on-4 rehabilitation at different occlusion position using T-Scan Ⅲ occlusal analysis system. METHODS Thirteen volunteers with All-on-4 rehabilitation were included in this study. T-Scan Ⅲ occlusal analysis system was used to measure the occlusal force distribution and the time character of the patients at intercuspal position, protrusive position, and lateral excursive position. RESULTS Maximum intercuspation: the left and right premolars took most of the occlusal force, namely (17.3±3.1)%, (15.8 ± 4.6)%, (15.5 ± 2.2)% and (15.2 ± 5.5)% (24, 25, 14, 15), the implants areas including the premolar and anterior teeth took (64.0±6.7)%, (19.2±8.0)% of occlusal force. The left and right sides took the respective percentages of (50.5±6.1)%, (49.5±6.1)%, and there was no difference. Protrusion position: the region (11, 12, 21, 22) commitment to take the percentage of (90.4±27.7)%. Occlusion time: 0.18(0.11, 0.26) s, disclusion time: 0.52 (0.35, 1.14) s . At the left and right lateral position, 8 patients were single teeth-supported occlusion, 5 patients were group fuctional occlusion, the average occlusion time was 0.20(0.13, 0.34) s, and DT was 1.07 (0.58, 1.46) s. CONCLUSIONS At maximum intercuspation: the implants areas including the premolar and anterior teeth were the occlusal force centers; the force concentrated in the area (11, 12, 21, 22) at the protrusion position. The lateral occlusal pattern shows multiformity.

Abstract
The dynamical backaction from a periodically driven optical cavity can reduce the damping of a mechanical resonator, leading to parametric instability accompanied by self-sustained oscillations. Here we study experimentally and theoretically new aspects of the backaction and the discrete time-translation symmetry of a driven system using a micromechanical resonator with two nonlinearly coupled vibrational modes with strongly differing frequencies and decay rates. We find self-sustained oscillations in both the low- and high-frequency modes. Their frequencies and amplitudes are determined by the nonlinearity, which also leads to bistability and hysteresis. The phase fluctuations of the two modes show near-perfect anti-correlation, a consequence of the discrete time-translation symmetry. Concurrently, the phase of each mode undergoes anomalous diffusion. The phase variance follows a power law time dependence, with an exponent determined by the 1/f-type resonator frequency noise. Our findings enable compensating for the fluctuations using a feedback scheme to achieve stable frequency downconversion. Dynamical backaction from a periodically driven cavity can reduce the damping of a mechanical resonator causing parametric instability. Here, the authors observe simultaneous self-sustained oscillations in both the mechanical and cavity modes and their correlated phase diffusion.

Abstract
OBJECTIVE To explore the relationship between the polymorphisms and haplotypes in the CETP gene and dyslipidemia among Xinjiang Kazak and Uygur residents. METHODS A population status survey was performed from 2010 to 2011 in Kashgar Xinjiang Uygur and Kazak residents, stratified cluster sampling method was used to select Uygur, Kazak residents with abnormal blood lipid values (n=367 and 345, respectively) as the dyslipidemia groups, and to select residents with normal lipid values as control group from the same area (n=374 and 390, respectively). SNaPshot technology was applied to detect the DNA of CETP gene rs3764261, rs1800775, rs708272 and rs5882 loci in all selected residents, and linkage disequilibrium analysis and haplotype construction were performed. RESULTS (1) In Uygur residents, the dyslipidemia risk of rs708272 CT (OR=0.64, 95%CI 0.46-0.91, P=0.01) and TT genotype (OR=0.60, 95%CI 0.40-0.91, P=0.02) was significantly lower than CC genotype. Dyslipidemia risk of rs3764261 GT (OR=0.55, 95%CI 0.40-0.74, P=0.00) and TT genotype (OR=0.47, 95%CI 0.28-0.78, P<0.01) was significantly lower than GG genetype. Dyslipidemia risk of the rs1800775 CC genotype was higher than AA genotype (OR=1.79, 95%CI 1.17-2.74, P=0.01). There was no statistical significance in CETP gene of the 4 genotype and allele frequency between the dyslipidemia and normal lipid groups in Kazak residents (all P>0.05). (2) In Uighur residents with dyslipidemia, HDL-C level was significantly higher in rs708272 TT genotype carriers than in CC and CT genotypes (all P<0.05) and in rs3764261 TT genotype carriers than in GG genotype carriers (P=0.008), while was significantly lower in rs1800775 CC genotype carriers with AA genotype carriers (P=0.008). (3) Linkage disequilibrium analysis showed that there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.869, r(2)=0.869), rs1800775 and rs708272 (D'=0.845, r(2)=0.446) in Uighur residents, and there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.963, r(2)=0.963), rs1800775 and rs708272 (D'=0.988, r(2)=0.630) in Kazak residents. (4) Significant differences were observed in frequency distribution of haplotype GACA(OR=0.579, 95%CI 0.388-0.864, P=0.006), GATA (OR=2.183, 95%CI 1.231-3.873, P=0.006), GCCA (OR=0.723, 95%CI 0.549-0.954, P=0.001), TATA (OR=0.723, 95%CI 0.549-0.954, P=0.021) and TATG (OR=0.601, 95%CI 0.429-0.841, P=0.002) in Uighur residents with normal or abnormal lipid profiles, while significant difference was observed in frequency distribution of haplotype GCCG (OR=1.961, 95%CI 1.207-3.188, P=0.005) in Kazak residents with normal or abnormal lipid profiles. CONCLUSION CETP genotype rs708272, rs3764261 and rs1800775 polymorphism is closely related to dyslipidemia and haplotype GACA, TATA and TATG will reduce the risk of dyslipidemia, while haplotype GATA, GCCA will increase the risk of dyslipidemia in Uygur residents. The four CETP polymorphisms are not related to the risk of dyslipidemia, but haplotype GCCG is related to increased risk of dyslipidemia in Kazakhs residents.

Abstract
The pharmacokinetics and bioavailability of butafosfan in piglets were investigated following intravenous and intramuscular administration at a single dose of 10 mg/kg body weight. Plasma concentration-time data and relevant parameters were best described by noncompartmental analysis after intravenous and intramuscular injection. The data were analyzed through WinNolin 6.3 software. After intravenous administration, the mean pharmacokinetic parameters were determined as T1/2λz of 3.30 h, Cl of 0.16 L kg/h, AUC of 64.49 ± 15.07 μg h/mL, Vss of 0.81 ± 0.44/kg, and MRT of 1.51 ± 0.27 h. Following intramuscular administration, the Cmax (28.11 μg/mL) was achieved at Tmax (0.31 h) with an absolute availability of 74.69%. Other major parameters including AUC and MRT were 48.29 ± 21.67 μg h/mL and 1.74 ± 0.29 h, respectively.

Abstract
OBJECTIVE To systematically review the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on two common respiratory system adverse events (RSAE: nasopharyngitis and upper respiratory tract infection) among type 2 diabetes (T2DM). METHODS Medline, Embase, Clinical trials and Cochrane library were searched from inception through May 2015 to identify randomized clinical trials(RCTs) assessed safety of GLP-1RAs versus placebo or other anti-diabetic drugs in T2DM. Network meta-analysis within a Bayesian framework was performed to calculate odds ratios for the incidence of RSAE. RESULTS In the study, 50 RCTs were included, including 13 treatments: 7 GLP-1RAs (exenatide, exenatide-long-release-agent, liraglutide, lixisenatide, taspoglutide, albiglutide and dulaglutide), placebo and 5 traditional anti-diabetic drugs(insulin, metformin, sulfonylureas, sitagliptin and thiazolidinediones ketones). Compared with insulin, taspoglutide significantly decreased the incidence of nasopharyngitis (OR=0.67, 95%CI: 0.46-0.96). Significant lowering effects on upper respiratory tract infection were found when taspoglutide versus placebo (OR=0.57, 95%CI: 0.34-0.99) and insulin (OR=0.39, 95%CI: 0.23-0.73). The result from the network meta-analysis based on Bayesian theory could be used to rank all the treatments included, which showed that taspoglutide ranked last with minimum risk on nasopharyngitis and upper respiratory tract infection. CONCLUSION Taspoglutide was associated with significantly lowering effect on RSAE.

Abstract
The aim of this study was to investigate the potential association between apolipoprotein A1 (APOA1) gene rs670, rs5069, and rs2070665 polymorphisms and dyslipidemia in the Kazakh population of Xinjiang, China. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify APOA1 (rs670, rs5069, and rs2070665) genotypes in 736 subjects (341 dyslipidemia patients and 395 control subjects). The frequencies of the CC genotype for rs1421085 were found to be 7.2% (obese group), 4.4% (overweight group), and 5.6% (control group). Polymorphisms of the three loci of the APOA1 gene in Kazakh subjects met Hardy-Weinberg equilibrium. The frequencies of the A allele for rs670 were found to be 14.3% (dyslipidemia group) and 12.7% (control group). The frequencies of the T allele for rs5069 and rs2070665 were: dyslipidmia group (7.2 and 30.1%, respectively) and control group (7.7 and 32.5%, respectively). Frequency distributions of the 3 types of genotypes and alleles of the three loci showed no statistically significant difference (P > 0.05). Significant differences were observed in lipoprotein (α) [Lp(α)] between patients with the rs2070665 CT + TT and CC genotypes (P < 0.05); however, none of the other relevant indicators differed significantly between the two genotypes. No significant association was identified between rs670 or rs5069 and the lipid-related metabolic indices assessed in the study. These findings indicate that the polymorphisms in the APOA1 gene (rs670, rs5069, and rs2070665) are not associated with dyslipidemia in the Kazakh population assessed in this study.

Abstract
NRAGE, a neurotrophin receptor-interacting melanoma antigen-encoding gene homolog, is significantly increased in the nucleus of radioresistant esophageal tumor cell lines and is highly upregulated to promote cell proliferation in esophageal carcinomas (ECs). However, whether the overexpressed NRAGE promotes cell growth by participating in DNA-damage response (DDR) is still unclear. Here we show that NRAGE is required for efficient double-strand breaks (DSBs) repair via homologous recombination repair (HRR) and downregulation of NRAGE greatly sensitizes EC cells to DNA-damaging agents both in vitro and in vivo. Moreover, NRAGE not only regulates the stability of DDR factors, RNF8 and BARD1, in a ubiquitin-proteolytic pathway, but also chaperons the interaction between BARD1 and RNF8 via their RING domains to form a novel ternary complex. Additionally, the expression of NRAGE is closely correlated with RNF8 and BARD1 in esophageal tumor tissues. In summary, our findings reveal a novel function of NRAGE that will help to guide personalized esophageal cancer treatments by targeting NRAGE to increase cell sensitivity to DNA-damaging therapeutics in the long run.

Abstract
We report the time-resolved excited state ultrafast dynamics of single unit cell (1 UC) thick FeSe films on SrTiO_{3} (STO), with FeTe capping layers. By measuring the photoexcited quasiparticles' density and lifetime, we unambiguously identify a superconducting (SC) phase transition, with a transition temperature T_{c} of 68 (-5/+2) K and a SC gap of Δ(0)=20.2±1.5 meV. The obtained electron-phonon coupling strength λ is as large as 0.48, demonstrating the likely crucial role of electron-phonon coupling in the high temperature superconductivity of the 1 UC FeSe on STO systems. We further find a 0.05 THz coherent acoustic phonon branch in the capping layer, which provides an additional decay channel to the gluing bosons.

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
AIMS The study aimed to perform a systematic investigation of the effects of quercetin on biofilm formation and virulence factors in Pseudomonas aeruginosa. METHODS AND RESULTS The Ps. aeruginosa strain PAO1 was selected as the test strain. The results indicated that quercetin did not impact the growth of PAO1 as determined by MIC and growth curve analysis. However, this compound significantly inhibited (P < 0·05) biofilm formation and production of virulence factors including pyocyanin, protease and elastase at a lower concentration than those for most previously reported plant extracts and substances. Considering the central role of quorum sensing (QS) in the regulation of biofilm and virulence factor, we further detected the transcriptional changes associated with QS and found that the expression levels of lasI, lasR, rhlI and rhlR were significantly reduced (P < 0·05) by 34, 68, 57 and 50%, respectively, in response to 16 μg ml(-1) quercetin. CONCLUSIONS This study indicated that quercetin is an effective inhibitor of biofilm formation and virulence factors in Ps. aeruginosa. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study to demonstrate that quercetin is an effective inhibitor of QS, biofilm formation and virulence factors in Ps. aeruginosa. Furthermore, quercetin might have potential in fighting biofilm-related infections.

Abstract
OBJECTIVE To analyze methodological bias and variation of systematic reviews on diagnostic test accuracy (DTA). METHODS Meta-analyses on DTA were identified through an electronic search through databases as Medline, Embase and Cochrane between 1 January 2008 and 31 December 2012. Results from Meta-analyses on 10 primary studies were included. Pairs of reviewers worked independently to extract the related data of interest, together with those original data of the primary studies. Mixed linear model was used to investigate the direction and strength of the association among the 14 studies, featuring on estimates of the diagnostic accuracy. RESULTS A total of 23 papers on Meta-analyses with 550 primary studies were included. Results from mixed linear model showed that significant low estimates of diagnostic accuracy in studies unsatisfying " the reference standard would likely to correctly classify the target condition" [relative diagnostic odds ration (RDOR) =0.018 6, 95% CI: 0.001 0-0.358 5]. Studies whose reference standard were not independent of the index test produced significantly higher estimates of diagnostic accuracy (RDOR= 2.396 6, 95% CI:1.242 8-4.622 7). CONCLUSION Messages as " Is the reference standard likely to correctly classify the target condition?" and " Was the reference standard independent of the index test", were the origin of the methodological bias and variation of systematic reviews on diagnostic test accuracy.

Abstract
The present study screened potential genes related to lung adenocarcinoma, with the
aim of further understanding disease pathogenesis. The GSE2514 dataset including 20
lung adenocarcinoma and 19 adjacent normal tissue samples from 10 patients with lung
adenocarcinoma aged 45-73 years was downloaded from Gene Expression Omnibus.
Differentially expressed genes (DEGs) between the two groups were screened using the
t-test. Potential gene functions were predicted using functional
and pathway enrichment analysis, and protein-protein interaction (PPI) networks
obtained from the STRING database were constructed with Cytoscape. Module analysis of
PPI networks was performed through MCODE in Cytoscape. In total, 535 upregulated and
465 downregulated DEGs were identified. These included ATP5D,
UQCRC2, UQCR11 and genes encoding nicotinamide
adenine dinucleotide (NADH), which are mainly associated with mitochondrial ATP
synthesis coupled electron transport, and which were enriched in the oxidative
phosphorylation pathway. Other DEGs were associated with DNA replication
(PRIM1, MCM3, and RNASEH2A),
cell surface receptor-linked signal transduction and the enzyme-linked receptor
protein signaling pathway (MAPK1, STAT3,
RAF1, and JAK1), and regulation of the
cytoskeleton and phosphatidylinositol signaling system (PIP5K1B,
PIP5K1C, and PIP4K2B). Our findings suggest that
DEGs encoding subunits of NADH, PRIM1, MCM3, MAPK1, STAT3, RAF1, and JAK1 might be
associated with the development of lung adenocarcinoma.

Abstract
BACKGROUND Transient elastography is a non-invasive method for staging liver fibrosis. The meta-analysis using the hierarchical models to evaluate the diagnostic accuracy of transient elastography for the staging of liver fibrosis in patients with chronic hepatitis B was rarely reported. AIM A meta-analysis using the hierarchical models was performed to assess transient elastography for diagnosing and stage liver fibrosis in patients with chronic hepatitis B. METHODS Electronic databases were searched and studies were identified to assess the diagnostic accuracy of transient elastography in CHB patients for staging fibrosis F ≥ 2, F ≥ 3 and F = 4 with liver biopsy as a reference standard. The hierarchical summary receiver operating characteristic curve and the bivariate models were performed to evaluate the diagnostic accuracy of transient elastography, and meta-regression analyses were performed to explore the heterogeneity. The quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess the quality of studies. RESULTS Twenty-seven studies with a total of 4386 patients were included in the meta-analysis. The summary sensitivity of transient elastography for staging fibrosis F ≥ 2, F ≥ 3 and F = 4 was 0.806 (95% CI, 0.756-0.847), 0.819 (95% CI, 0.748-0.874) and 0.863 (95% CI, 0.818-0.898), respectively, and the summary specificity was 0.824 (95% CI, 0.761-0.873), 0.866 (95% CI, 0.824-0.899) and 0.875 (95% CI, 0.840-0.903), respectively. The corresponding area under the summary receiver operating characteristic curve was 0.88 (95% CI, 0.85-0.91), 0.91 (95% CI, 0.88-0.93) and 0.93 (95% CI, 0.91-0.95), respectively. Meta-regression showed that patient age contributed to heterogeneity. CONCLUSIONS Transient elastography performs well to diagnose liver fibrosis in patients with chronic hepatitis B, which may reduce the use of liver biopsy.

Abstract
The aim of this study was to assess the association between three FTO polymorphisms (rs9939609, rs8057044, and rs1421085) and metabolic syndrome (MS)-related outcomes in the low-income, rural, nomadic minority Khazakh population in far western China. A total of 489 subjects (245 MS patients, 244 controls) were included in the study and DNA samples were genotyped for the three polymorphisms by matrix-assisted laser desorption/ionization time of flight mass spectrometry. The frequencies of the rs1421085 and rs9939609 genotypes and alleles did not differ significantly between MS patients and control, while the frequencies of rs8057044 G alleles and GG genotypes were higher in MS patients (P < 0.05) than in control subjects (G: 61.16 vs 53.53%, GG: 39.07 vs 29.05%) and the frequencies of rs8057044 A genotypes and alleles were lower (P < 0.05) in MS patients compared with controls (AA: 17.36 vs 21.99%, A: 38.84 vs 46.47%). Risk analysis of the rs8057044 polymorphism revealed individuals with GA and GG genotypes to have 1.112 and 1.731 times higher risks of developing MS than those with the AA genotype, respectively, while the G allele was found to be associated with a 1.367 times higher risk of developing MS compared with the A allele. These apparent correlations, however, did not hold true when adjusted for BMI. Weight, WC, HC, and BMI differed significantly between rs8057044 GG and AA+GA genotypes (P < 0.05).

Abstract
Long non-coding RNAs (lncRNAs), which are extensively transcribed from the genome, have been proposed to be key regulators of diverse biological processes. However, little is known about the role of lncRNAs in regulating spermatogenesis in human males. Here, using microarray technology, we show altered expression of lncRNAs in the testes of infertile men with maturation arrest (MA) or hypospermatogenesis (Hypo), with 757 and 2370 differentially down-regulated and 475 and 163 up-regulated lncRNAs in MA and Hypo, respectively. These findings were confirmed by quantitative real-time PCR (qRT-PCR) assays on select lncRNAs, including HOTTIP, imsrna320, imsrna292 and NLC1-C (narcolepsy candidate-region 1 genes). Interestingly, NLC1-C, also known as long intergenic non-protein-coding RNA162 (LINC00162), was down-regulated in the cytoplasm and accumulated in the nucleus of spermatogonia and primary spermatocytes in the testes of infertile men with mixed patterns of MA compared with normal control. The accumulation of NLC1-C in the nucleus repressed miR-320a and miR-383 transcript and promoted testicular embryonal carcinoma cell proliferation by binding to Nucleolin. Here, we define a novel mechanism by which lncRNAs modulate miRNA expression at the transcriptional level by binding to RNA-binding proteins to regulate human spermatogenesis.

Abstract
Urinary neutrophil gelatinase-associated lipocalin (uNGAL) is relatively specific in lupus nephritis (LN) patients. However, its diagnostic value has not been evaluated. The aim of this review was to determine the value of uNGAL for diagnosis and estimating activity in LN. A comprehensive search was performed on PubMed, EMBASE, Web of Knowledge, Cochrane electronic databases through December 2014. Meta-analysis of sensitivity and specificity was performed with a random-effects model. Additionally, summary receiver operating characteristic (SROC) curves and area under the curve (AUC) values were calculated. Fourteen studies were selected for this review. With respect to diagnosing LN, the pooled sensitivity and specificity were 73.6% (95% confidence interval (CI), 61.9–83.3) and 78.1% (95% CI, 69.0–85.6), respectively. The SROC-AUC value was 0.8632. Regarding estimating LN activity, the pooled sensitivity and specificity were 66.2% (95% CI, 60.4–71.7) and 62.1% (95% CI, 57.9–66.3), respectively. The SROC-AUC value was 0.7583. In predicting renal flares, the pooled sensitivity and specificity were 77.5% (95% CI, 68.1–85.1) and 65.3% (95% CI, 60.0–70.3), respectively. The SROC-AUC value was 0.7756. In conclusion, this meta-analysis indicates that uNGAL has relatively fair sensitivity and specificity in diagnosing LN, estimating LN activity and predicting renal flares, suggesting that uNGAL is a potential biomarker in diagnosing LN and monitoring LN activity.

Abstract
WHAT IS KNOWN AND OBJECTIVE Research on genetic factors associated with antitubercular drug-induced liver injuries (ATLI) has been reported. However, most of the research has focused on genetic polymorphisms of genes encoding metabolic enzymes, including NAT2, GST and CYP450. It is probable that the immune system also contributes to the onset of drug adverse effects. A few small studies have explored the possible association of HLA genes with drug-induced liver injuries (DILI), but more supportive evidence from larger studies or prospective cohort designs is needed. We aim to explore the possible association of HLA-DQB1 gene polymorphisms with ATLI in a case-control study. METHODS A case-control study design was used. ATLI was recorded in a prospectively followed-up cohort of patients receiving antituberculosis treatment. Identified cases were matched with control tuberculosis patients within the same cohort but with no adverse effects in 1 : 1 ratio. We used the sequence-based typing method to determine the HLA-DQB1 genotypes. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using conditional logistic regression. RESULTS AND DISCUSSION Eighty-nine cases were included in this case-control study. HLA-DQB1 typing was successful for 177 subjects. No association between frequency of HLA-DQB1 genotypes and ATLI was statistically significant in univariate analyses. Multivariate analysis using the conditional logistic regression model revealed that the individuals with two DQB1*05 alleles were at higher risk of ATLI than control subjects. The OR was 5.28 adjusted for use of liver protective drugs and weight (10/88 VS 2/88, 95% CI: 1.134-24.615, P = 0.034). Analysis according to the liver injury type showed that both mixed liver injury patients and cholestatic/mixed liver injury patients had higher proportions of DQB1*05 : 02 alleles (P values were 0.028 and 0.005, respectively). WHAT IS NEW AND CONCLUSION This study suggests that ATLI was more likely in subjects of HLA-DQB1*05/*05 genotype. Further studies are needed to verify this association.

Abstract
AIM To compare the effects of additional educational material on treatment satisfaction of overactive bladder (OAB) patients treated with a muscarinic receptor antagonist. METHODS In an observational study of OAB patients being treated by their physician with fesoterodine for 4 months (FAKTEN study), sites were randomised to providing standard treatment or additional educational material including the SAGA tool. Patient satisfaction was assessed by three validated patient-reported outcomes including the Treatment Satisfaction Question. Because of premature discontinuation of the study, descriptive statistical analysis was performed. RESULTS A total of 431 and 342 patients received standard treatment or additional educational material, respectively. At study end, 76.1% [95% CI = 71.3, 80.4] of patients with standard care and 79.6% [95% CI = 74.4, 84.1] with additional SAGA tool were satisfied with treatment (primary end-point). Comparable outcomes with and without the additional educational material were also found in various patient subgroups, at the 1-month time point, and for the other patient-reported outcomes. A notable exception was the subgroup of treatment-naïve patients in which the percentage of satisfied patients was 77.2% vs. 89.5% with standard treatment and additional SAGA tool, respectively (post hoc analysis). DISCUSSION AND CONCLUSIONS In an observational study, most overactive bladder patients were satisfied with fesoterodine treatment. Because of the small sample size, the study does not support or refute the hypothesis that adding the SAGA tool will improve patient satisfaction with treatment. The potential effect of additional educational material in treatment-naïve patients warrants further dedicated studies.

Abstract
This study aims to evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer after neoadjuvant chemotherapy (NAC). Articles were searched in Medline, Pubmed, Cochrane Database of Systemic Reviews, Google scholar, and EMBASE. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios (LR), and diagnostic odds ratio (DOR). Pooling was conducted using either fixed-effects model or random-effects model depending on the heterogeneity across studies. Sixteen studies (n = 724) were included in this analysis. The pooled sensitivity and specificity of EUS to diagnose T1 stage tumor was 23% (95% confidence interval [CI] 16-32%) and 95% (95%CI 93-97%), respectively. For T2 stage, EUS had a pooled sensitivity and specificity of 29% (95%CI 19-41%) and 84% (95%CI 77-88%). The pooled sensitivity and specificity of EUS were 81% (95%CI 72-88%) and 42% (95%CI 33-52%) in determining T3 stage tumor. To diagnose T4 stage tumor, EUS had a pooled sensitivity of 43% (95%CI 31-56%) and specificity of 96% (95%CI 94-97%), respectively. In determining N stage, the pooled sensitivity and specificity of EUS were 69% (95%CI 58-79%) and 52% (95%CI 42-62%). EUS is a moderately accurate technique in staging esophageal cancer after NAC. Its sensitivity is relatively high in T3 while specificity is high in other T stages (T1, T2, and T4). Tumors restaged by EUS as T4 should not be assigned to surgery because it is very likely to be inoperable. EUS is not reliable for N staging with its poor sensitivity and specificity. Subgroup analysis shows that staging accuracy did not improve with time.
