Abstract
Objective:To investigate the application value of carbon nanoparticle lymph tracer in Ⅵ lymph node dissection for papillary thyroid cancer.Method:One hundred and forty-eight patients with papillary thyroid cancer from October 2015 to May 2016 were enrolled into the retrospective analysis. Seventy-five cases with carbon nanoparticle injected in operation were divided into observation group, while the other seventy-three cases without lymph tracer were divided into control group. The number of neck Ⅵ lymph nodes and metastatic lymph nodes between the two groups were compared, as well as the incidence of parathyroid injury and postoperative hypocalcemia. Result:There were no significant difference in age, gender, tumor size, pathology or type of operation between the two groups(P>0.05). Parathyroid injury incidence in the observation group significantly lower than the control group (5.33% vs 5.33%, P< 0.05). There was significant difference in the number of neck Ⅵ lymph node dissection between the two groups (observation group: 6.51±4.65, control group: 4.42±3.10, P< 0.05).Conclusion:Carbon nanoparticle injected as a lymph tracer in thyroid surgery is helpful, the characteristics of the parathyroid gland negative imaging can effectively decrease the rate of parathyroid gland injury.

Abstract
OBJECTIVE Hepatic encephalopathy is a common consequence of liver cirrhosis, but diagnosis can be difficult as it is based on clinical criteria alone. We hypothesised that serum prealbumin, cholinesterase and retinol binding protein (RBP) can help support the diagnosis of hepatic encephalopathy. METHODS We enrolled 306 cirrhotic patients (110 with encephalopathy), 100 chronic hepatitis B patients and 50 healthy controls, measuring routine liver function tests (ALT, AST, GGT, ALP, and bilirubin), albumin, prothrombin time, prealbumin, cholinesterase and RBP by routine methods. Logistic regression analysis and areas under the receiver operating characteristic curves (AUCs) were used to find predictive factors for hepatic encephalopathy. RESULTS There were differences in all laboratory indices between the three groups (all p < 0.001). In univariate analysis, albumin, prothrombin time, prealbumin, cholinesterase and RBP were significantly altered in those with encephalopathy (p < 0.01), but only prealbumin, cholinesterase and RBP levels were significant predictors in multivariate analysis, and each was linked to the severity of liver fibrosis defined by the Child-Pugh score (all p < 0.001). The AUCs (95% CI) of prealbumin, cholinesterase and RBP for diagnosing liver cirrhosis with hepatic encephalopathy were comparable at 0.85 (81-90), 0.81 (0.76-0.85) and 0.81 (0.76-0.86), respectively (all p < 0.01). CONCLUSIONS Serum prealbumin, cholinesterase and RBP levels are of potential clinical value in diagnosis of liver cirrhosis complicated by encephalopathy.

Abstract
BACKGROUND Mesenchymal stem cell (MSC) treatment has emerged as an important adjunct therapy for heart failure. However, the use of MSC to treat heart failure has not been well established. We conducted a systematic review and meta-analysis to evaluate the efficacy of MSC treatment for heart failure. METHODS PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched. Randomized controlled trials (RCTs) assessing the influence of MSC treatment on cardiac function in heart failure were included in this analysis. Two investigators independently searched the articles, extracted data, and assessed the quality of the included studies. Meta-analysis was performed using the fixed-effect model or random-effect model when appropriate. RESULTS Six RCTs involving 625 patients were included in the meta-analysis. Compared with control interventions in heart failure patients, MSC treatment had no significant influence on cardiovascular death (RR = 0.76; 95% CI = 0.38-1.52; p = 0.43); however, it was associated with significantly increased left ventricular ejection fraction (LVEF; mean = 9.64; 95% CI = 7.56-11.71; p < 0.00001) and reduced rehospitalization rate (RR = 0.41; 95% CI = 0.23-0.73; p = 0.003). In addition, no significant difference between the two groups was observed for the incidence of myocardial infarction (RR = 0.72; 95% CI = 0.10-5.02; p = 0.74), the recurrence of heart failure (RR = 0.88; 95% CI = 0.28-2.81; p = 0.83), and total death (RR = 0.68; 95% CI = 0.37-1.25; p = 0.21). CONCLUSION Although MSC treatment can significantly improve LVEF and reduce rehospitalization rates, it does not have a significant influence on cardiovascular death, myocardial infarction, heart failure, and total death.

Abstract
Objective: To explore the relationship between job stress, work engagement and depressive symptoms of State Grid workers, and to analyze the mediating effect of work engagement between job stress and depressive symptoms. Methods: A cross-sectional survey was conducted to investigate 845 employees from a State Grid company, using the brief job stress questionnaire, the Patient Health Questionnaire (PHQ-9) and 9-item Utrecht Work Engagement Scale (UWES-9) in March 2017. Results: The average score of work engagement was 4.49±1.42, the mean value of job stress was 1.15±0.33, the average score of depressive symptoms was 6.44±4.30, and the positive rate of depressive symptoms was 66.9%.There was a negative correlation between work engagement with both job stress and depressive symptoms (r=-0.193, -0.397, both P<0.01) , and job stress was positively correlated with depressive symptoms (r=0.260, P<0.01) . The relationship between job stress and depressive symptoms was partly mediated by work engagement, and the mediating effect accounted for 27.2% of the total effect. Conclusion: The work engagement of State Grid staff acts as the mediator between job stress and depressive symptoms, alleviating the depressive symptoms caused by job stress.

Abstract
Objective: This study was to understand the current situation of long working hours and identify the association of long working hours and job stress and depression among workers from one district company of state grid. Methods: The project was done with the cross-sectional survey. All questionnaires were completed by self-administered with informed consent. Employees' weekly working hours was reported by themselves; Using the PHQ-9 scale to assess depression, the JDC Model to evaluate job stress, and SPSS software to analyze data, the single factor chi-square test and multivariate Logistic analysis were performed to identify the association between long working hours and job stress, depression. Results: there were 35.3 percent employees with over 44 hours a week. The association between increasing weekly working hours and job stress and depression was statistically significant. Compared to the reference group (≤44 h) , for those who worked more than 44 hours per week, the odds ratio of job stress was 2.02 (95%CI=1.27-3.23) times increased, and the odds ratio of depression was 1.60 (95%CI=1.01-2.55) times increased, especially for those (≥60 h) , the odds ratio was 3.69 (95%CI=1.45-9.41) and 2.76 (95%CI=1.09-7.03) respectively. Conclusion: Long working hours can significantly increase the risk of job stress and depression among workers. When their weekly working hours exceeds 60, long working hours will be the independent risk factor for both job stress and depression.

Abstract
Objective: To discuss the effect and safety of continuous pumping for home enteral nutrition after esophagectomy. Methods: The current study retrospectively analyzed the esophageal cancer patients who underwent transthoracic esophagectomy between January 2017 and November 2017 at First Department of Thoracic Surgery, Peking University Cancer Hospital and Institute. There were totally 108 cases, including 88 males and 20 females, with an average age of 62 years. The patients were divided into pump feeding group (n=56) and traditional tube feeding group (n=52). The postoperative short-term safety, weight maintenance, enteral nutrition tolerance and nutritional support complete rate of the 2 groups were compared by χ(2) test, Fisher exact test and t test, respectively. Results: Compared with traditional tube feeding group, the patient safety in pumping feeding group was significantly better, with complications within 2 months after discharge were 11/52 and 4/56 respectively (χ(2)=2.393, P=0.035); the weight maintenance was significantly better, the weight loss within 4 weeks after discharge were 3.90 kg and 0.13 kg, respectively (t=7.720, P=0.000); the general enteral complications were significantly lower (26/52 vs. 5/56, χ(2)=22.225, P=0.000), the nutritional support complete rate was significantly higher (23/52 vs. 55/56, χ(2)=39.167, P=0.000). Conclusions: Continuous pump feeding enteral nutrition support after discharge postoperatively could help improve patient safety after discharge, which is better for weight maintenance of the patients. Pump feeding could also enhance tolerability of tube feeding and ensure the effective accomplishment of nutritional support.

Abstract
OBJECTIVES To analyze the relationship between the suicide method and the sex, age, education background and cause of suicide to provide reference for the forensic identification of suicide. METHODS After scene investigation, external body examination, autopsy and case investigation, 124 identified suicide cases which happened in recent three years in Wuhua district in Kunming were collected. Analytical methods as chi-square test and descriptive statistics were performed by SPSS 22.0. RESULTS In all the suicide cases, male to female ratio was 1.53∶1. The suicide methods were mainly fatal fall, hanging and drowning. The ratio of local to non-native residents was 1∶1. The suicide rate in the people with primary school or junior middle school education level was highest. The group of >10-50 years tended to choose fatal fall suicide and people over 60 years were more likely to choose hanging. People with different academic background tended to choose fatal fall suicide. The suicide methods as fatal fall and hanging were chosen because of mental and physical diseases and economic problems, while the suicides with emotional problems were more likely to choose fatal fall and poisoning. CONCLUSIONS Suicide belongs to a kind of complex cases. For the cases of suspected suicide, complete exploration and overall consideration should be done to determine the nature of cases based on comprehensive analysis of all the influence factors.

Abstract
Objective: To evaluate the value of (18)F-FDG PET/CT in predicting long-term survival of esophageal squamous cell carcinoma(ESCC) before initial treatment. Methods: A total of 167 ESCC patients were retrospectively analyzed who underwent surgery between January 2010 and December 2014 in prospective database of Peking University Cancer Hospital Thoracic Surgery Department One, all cases were included according to inclusion and exclusion criteria.The relationship between SUVmax of the primary tumor and patients' age, gender, tumor location, tumor differentiation, tumor regression grade as well as long term survival were compared. Results: The median follow-up time of the 167 cases was 46.9 months(ranging from 30.5 to 86.2 months), with 1 year and 3 years postoperatively being 95.1% and 68.4%, respectively.The SUVmax of the tumor was positively correlated with cT(P<0.01), cN(P=0.033), cTNM(P=0.002) and pTNM(P=0.003)of the tumor.Patients with SUVmax ≤6 obtained a survival significantly better compared with patients with SUVmax>6, the 3 years OS were 83.4 % vs 65.6% (P=0.02) , and DFS were 82.4% vs 55.4%(P=0.006), respectively.The multivariate regression analysis demonstrated that the SUVmax>6 before treatment was the independent prognostic factor for OS (HR=3, 95%CI 1.050-8.568) and DFS (HR=3.971, 95% CI 1.408-11.200) of the ESCC patients. Conclusions: The higher the (18)F-FDG PET/CT SUVmax of the ESCC primary tumor, the poorer survival of the patients. Therefore, SUVmax could be used as an indicator to predict long term survival of the ESCC patients before treatment.

Abstract
A series of trifluoromethyl pyridine derivatives containing 1,3,4-oxadiazole moiety was designed, synthesized and bio-assayed for their insecticidal activity. The result of bio-assays indicated the synthesized compounds exhibited good insecticidal activity against Mythimna separata and Plutella xylostella, most of the title compounds show 100% insecticidal activity at 500 mg L−1 and >80% activity at 250 mg L−1 against the two pests. Compounds E18 and E27 showed LC50 values of 38.5 and 30.8 mg L−1 against Mythimna separata, respectively, which were close to that of avermectin (29.6 mg L−1); compounds E5, E6, E9, E10, E15, E25, E26, and E27 showed 100% activity at 250 mg L−1, which were better than chlorpyrifos (87%). CoMFA and CoMSIA models with good predictability were proposed, which revealed the electron-withdrawing groups with an appropriate bulk at 2- and 4-positions of benzene ring could enhance insecticidal activity. Novel trifluoromethyl pyridine derivatives bearing 1,3,4-oxadiazole whereas synthesized, their which showed good insecticidal activity; a 3D-QSAR model with good predictability was is proposed.![]()

Abstract
PRAS40 has been shown to have a crucial role in the repression of mammalian target of rapamycin (mTOR). Nonetheless, PRAS40 appears to have an oncogenic function in cancer cells. Whether PRAS40 mediates signaling independent of mTOR inhibition in cancer cells remains elusive. Here PRAS40 overexpression in lung adenocarcinoma and cutaneous melanoma was significantly correlated to worse prognosis. And we identified an unexpected role for PRAS40 in the regulation of nuclear factor (NF)-κB signaling. P65, a subunit of the NF-κB transcription factor complex, was confirmed to associate with PRAS40 by glutathione S-transferase co-precipitation. Importantly, we found that PRAS40 can enhance NF-κB transcriptional activity in a manner dependent upon PRAS40–P65 association. Furthermore, we found that a small p65-derived peptide can disrupt the PRAS40–P65 association and significantly decrease NF-κB transcriptional activity. These findings may help elucidate the pleiotropic functions of PRAS40 in cells and suggest a novel therapeutic strategy in cancer patients with high expression of PRAS40 and NF-κB.

Abstract
RNA interference (RNAi) is a powerful tool to silence or minimize gene expression, and palate culture in vitro is an important technique for study of the palate development. Our previous study demonstrated that the gene expression of glucose-regulated protein-78 (Grp78) was downregulation in the all-trans retinoic acid-induced mouse models of cleft palate (CP) during embryogenesis. To find the role of Grp78, the small interfering RNA (siRNA) of this gene carried by fluorescent vector was injected with a microinjector, through which about 30 pmol siRNA was injected into the Institute of Cancer Research (ICR) mouse palate explants. After 6, 12, 24, 48, and 72 h, these palate explants were removed from culture to observe their fluorescent and Alcian blue-staining phenotypes, and the expression of the unfolded protein response (UPR) key members (Grp78, Inositol-responsive enzyme 1, protein kinase RNA-like endoplasmic reticulum kinase, activating transcription factor-6 and X-box binding protein-1) was measured. After cultured for 72 h, the partially or completely fused bilateral palates were observed in the control siRNA group, while CPs were found in the Grp78 siRNA group. In the Grp78 siRNA group, the relatively mRNA abundance of the key genes belonged to UPR at each time point was lower than that of the control siRNA group, and their protein expression also displayed the same change. By the system of RNAi strategies with mouse palate culture, we found the siRNA of Grp78 disturbed the fusion of mouse palate cultured in vitro.

Abstract
Objective: To explore a model that workplace social capital is associated with intention to stay (ITS) in the nursing profession and that this association is partially mediated by organizational commitment, job satisfaction, and job stress among Chinese nurses. Methods: A cross-sectional, observationalstudy was conducted in Shanghai, China between September and December 2014. Two thousandforty-two nurses from 23 healthcare organizations were recruited for the current study using a two-stage sampling process.Intention to stay, workplace social capital, job satisfaction, organizational commitment, and job stress was measured by validated scale. Measured variable path analysis (MVPA) was used to test their hypothesized relationships. Results: There were significant positive direct effects from workplace social capital (β=0.11, P<0.01) , organizational commitment (β=0.81, P<0.01) and job satisfaction (β=0.03, P<0.01) to ITS, and a negative direct effects from job strain to ITS (β=-0.03, P<0.01) . The model explained 84% of the variability in ITS. Additionally, workplace social capital had significant positive direct effects on organizational commitment (β=0.65, P<0.01) , job satisfaction (β=0.44, P<0.01) and negative direct effects on job strain (β=-0.35, P<0.01) . The indirect effect of social capital to ITS was 0.55. Job satisfaction was positively associated with organizational commitment (r=0.47, P<0.01) , and negtively associated with job stress (r=-0.12, P<0.01) . Job stress was negtively associated with organizational commitment (r=-0.20, P<0.01) . Conclusion: This study suggests that greater workplace social capital may lead to higher ITS in nursing primarily by increasing commitment to the nursing occupation and their job satisfaction and by reducing their sense of job stress.

Abstract
Mucopolysaccharidosis type III is a group of four autosomal recessive enzyme deficiencies leading to tissue accumulation of heparan sulfate. Central nervous system disease is prominent, with initial normal development followed by neurocognitive decline leading to death. In order to define outcome measures suitable for gene transfer trials, we prospectively assessed disease progression in MPS IIIA and IIIB subjects >2years old at three time points over one year (baseline, 6 and 12months). Fifteen IIIA (9 male, 6 female; age 5.0±1.9years) and ten IIIB subjects (8 male, 2 female; age 8.6±3years) were enrolled, and twenty subjects completed assessments at all time points. Cognitive function as assessed by Mullen Scales maximized at the 2.5 to 3year old developmental level, and showed a significant age-related decline over a 6month interval in three of five subdomains. Leiter nonverbal IQ (NVIQ) standard scores declined toward the test floor in the cohort by 6 to 8years of age, but showed significant mean declines over a 6month interval in those <7years old (p=0.0029) and in those with NVIQ score≥45 (p=0.0313). Parental report of adaptive behavior as assessed by the Vineland-II composite score inversely correlated with age and showed a significant mean decline over 6month intervals (p=0.0004). Abdominal MRI demonstrated increased volumes in liver (mean 2.2 times normal) and spleen (mean 1.9 times normal) without significant change over one year; brain MRI showed ventriculomegaly and loss of cortical volume in all subjects. Biochemical measures included urine glycosaminoglycan (GAG) levels, which although elevated showed a decline correlating with age (p<0.0001) and approached normal values in older subjects. CSF protein levels were elevated in 32% at enrollment, and elevations of AST and ALT were frequent. CSF enzyme activity levels for either SGSH (in MPS IIIA subjects) or NAGLU (in MPS IIIB) significantly differed from normal controls. Several other behavioral or functional measures were found to be uninformative in this population, including timed functional motor tests. Our results suggest that cognitive development as assessed by the Mullen and Leiter-R and adaptive behavior assessment by the Vineland parent interview are suitable functional outcomes for interventional trials in MPS IIIA or IIIB, and that CSF enzyme assay may be a useful biomarker to assess central nervous system transgene expression in gene transfer trials.

Abstract
Total hip arthroplasty is effective in reducing pain and improving functional outcome for a variety of hip pathologies. Approximately 27% patients, however, complain of pain at 6 months' follow-up following surgery. The pain may worsen over time and can become severe and chronic in around 4% of patients who ultimately require revision surgery. Therefore, it is important for clinicians to comprehensively assess patients undergoing total hip arthroplasty in order to identify the underlying pathology of a painful hip and then offer prompt treatment. Causes of hip pain after total hip arthroplasty are analysed in this article, as well as the systematic approach to evaluation and appropriate diagnostic investigations.

Abstract
Objective: To investigate understand the current status of the sense of coherence and occupational stress in modern service workers, and to analyze the association between occupational stress and the sense of coherence. Methods: From March to April, 2016, 834 modern service workers from 3 companies in Shanghai, China (in air transportation industry, marketing industry, and travel industry) were surveyed by non-ran-dom sampling. The self-completion questionnaires were filled out anonymously given the informed consent of the workers. The occupational stress questionnaire was used to evaluate occupational stress, and the Chinese version of the Sense of Coherence Scale (SOC-13) was used to assess the mental health. Results: The mean score for the sense of coherence of the respondents was 61.54±10.46, and 50.1% of them were self-rated as having occupational stress. There were significant differences in SOC score between groups with different ages, marital status, positions, lengths of service, family per capita monthly income, and weekly work hours (P<0.05). The occupational stress score differed significantly across groups with different marital status, lengths of service, and weekly work hours (P<0.05). The scores for working autonomy, social support, and occupational stress differed significantly between groups with different SOC levels (P<0.05). There were significant differences in SOC score and the distribution of low-SOC respondents between groups with different levels of working autonomy, social support, and occupational stress. High SOC is a protective factor for occupational stress (OR=0.39, 95%CI 0.26~ 0.59). Conclusion: Modern service workers in Shanghai have high SOC and moderate occupational stress. Therefore, improving SOC may reduce occupational stress.

Abstract
Feminization-1 homolog b (Fem1b) is one of the genes essential for male development and play central roles in sex determination of Caenorhabditis elegans. In this study, we cloned and characterized the full-length Fem1b cDNA from the freshwater prawn Macrobrachium nipponense (MnFem1b) in different tissues and at different developmental stages. Real-time quantitative reverse polymerase chain reaction (RT-qPCR) showed that the MnFem1b gene was expressed in all investigated tissues, with the highest expression level found in the testes. The results revealed that the MnFem1b gene might play roles in aspects of development of the male prawn phenotype. The RT-qPCR also revealed that MnFem1b mRNA expression was significantly increased at 10 days after metamorphosis. The expression levels in all investigated tissues showed a certain degree of sexually dimorphism, the expression levels in males were significantly higher than those in females (P < 0.05). Notably, the highest expression of MnFem1b was found in the testes. The expression of MnFem1b in different tissues indicates that it plays multiple biological functions in M. nipponense.

Abstract
BACKGROUND Glucagon-like peptide-1 (GLP-1) receptor agonists are an established treatment for people with type 2 diabetes (T2D). We aimed to indirectly compare two GLP-1 receptor agonists, once weekly dulaglutide 1.5 mg and once daily liraglutide 1.8 mg, as a part of clinical trial planning. METHODS Studies for inclusion in the network meta-analysis (NMA) included all available dulaglutide and liraglutide data as of November 2011 as well as results from the exenatide once weekly registration programme. Change from baseline in haemoglobin A1c (A1c) was the primary endpoint, and a 26-week treatment effect was estimated. RESULTS Data for 7135 people with T2D from 15 randomised controlled trials (RCTs) followed for 12-52 weeks were included in the quantitative analysis. Observed results from the NMA predicted an A1c change from baseline of -15.1 mmol/mol (-1.38%) in the dulaglutide 1.5 mg group and -14.7 mmol/mol (-1.34%) in the liraglutide 1.8 mg group, with a predicted treatment difference (dulaglutide-liraglutide) of -0.4 mmol/mol (-0.04%) [95% credible interval: -2.4 to 1.5 mmol/mol (-0.22% to 0.14%)]. CONCLUSIONS The subsequent RCT primary result of a -0.7 mmol/mol (-0.06%) treatment difference (dulaglutide-liraglutide) in A1c demonstrated that once weekly dulaglutide 1.5 mg and once daily liraglutide 1.8 mg resulted in similar glycaemic control, which was consistent with the NMA-predicted treatment difference. NMA is a useful tool and should be considered during clinical trial planning.

Abstract
This study aimed to explore the influence of umbilical cord mesenchymal stem cells (UMSC) on stem cell homing and glomerular mesangial cell (GMC) after intravenous injection performed on mice tails with IgA nephropathy (IgAN) and its possible mechanism, which provide a new way and theoretical basis for the application of stem cell transplantation (SCT) in kidney disease treatment. Specific pathogen free (SPF) male Kunming mice were randomly divided into groups. A complex method applying bovine serum albumin (BSA) gavage, hypodermic injection of CCl4 and lipopolysaccharide (LPS) was used for building IgAN mice model. In addition, vascular endothelial growth factor (VEGF), connective tissue growth factor (CTGF) and cluster of differentiation (CD) 44 were observed by Masson staining and detected with immunohistochemistry (IHC) to confirm homing and location of mesenchymal stem cells (MSCs). Moreover, Western Blot was used for detecting VEGF and CTGF so as to explore the possible mechanism of applying UMSC in treating IgAN. Masson staining indicated that fibrosis degree of MSCs in treatment group was significantly lower than in negative control group after stem cell treatment. Routine urine test explained that proteinuria in treatment group were (7.15±0.31), (4.87±0.22), (2.95±0.16) g/24 h and (12.00±1.38) g/24 h in model group (P less than 0.05). MSCs were observed to be located in glomerulus and renal interstitium by IHC detection of CD44 and IHC qualitative observation of VEGF and CTGF had different positive expressions in three groups. Furthermore, different expressions of VEGF and CTGF were observed quantitatively by Western Blot. Fibrosis degree of renal tissue relieves, hematuresis and proteinuria eases and IgAN symptoms obviously improve after UMSC treatment, which hints that the treatment of HUMSC has protective effect on IgAN mice model.

Abstract
Over the past three decades, both Shanghai and New York City (NYC), have experienced dramatic rises in childhood obesity rates. Given the role that obesity plays in the aetiology of chronic diseases such as diabetes and heart disease, the elevated rates are a major concern. Despite differences in governance systems and cultures, Shanghai and NYC have experienced rapid industrialization, a growing population and a rise in income inequality. The prevalence of childhood obesity in Shanghai and NYC is greater than their respective national rate. However, the trajectory and development of this epidemic has differed between the cities. The distribution of obesity by race and ethnicity, socio-economic status, sex, and age differs markedly between the two cities. To reduce prevalence and inequities within this complex epidemic requires an understanding of the dynamic changes in living conditions among social groups in each city and the behaviours that are influenced by such changes. By comparing changes in the influences on dietary behaviours, such as food distribution, pricing, gender values, and media and marketing, this highlights opportunities for Shanghai, NYC, and other world cities with high or rising rates of childhood obesity to inform future program and policy initiatives. It reiterates the importance of a comprehensive and multilevel approach that includes action at the individual, family, community, municipal, national, and global levels.

Abstract
AIM To describe the clinical effects of single and multiple doses of a potent, selective, orally administered, small-molecule antagonist of the human glucagon receptor, LY2409021, in healthy subjects and in patients with type 2 diabetes. METHODS LY2409021 was administered in dose-escalation studies to healthy subjects (n = 23) and patients with type 2 diabetes (n = 9) as single doses (Study 1) and daily to patients with type 2 diabetes (n = 47) for 28 days (Study 2). Safety, tolerability, pharmacokinetic (PK) and pharmacodynamic (PD) assessments were made after single doses and in patients receiving once-daily doses of LY2409021 (5, 30, 60 or 90 mg) for 28 days. RESULTS LY2409021 was well tolerated at all dose levels in both studies. Fasting and postprandial glucose were reduced and glucagon levels increased after single and multiple dosing, with reductions in fasting serum glucose of up to ∼1.25 mmol/l on day 28. Serum aminotransferases increased in a dose-dependent manner with multiple dosing and reversed after cessation of dosing. Significant glucose-lowering was observed with LY2409021 at dose levels associated with only minor aminotransferase increases. CONCLUSION Blockade of glucagon signalling in patients with type 2 diabetes is well tolerated and results in substantial reduction of fasting and postprandial glucose with minimal hypoglycaemia, but with reversible increases in aminotransferases. Inhibition of glucagon signalling by LY2409021 is a promising potential treatment for patients with type 2 diabetes and should be evaluated in longer clinical trials to better evaluate benefits and risks.

Abstract
AIM We aim to assess the effects of recombinant human thyrotropin (rhTSH) versus thyroid hormone withdrawal (THW), and rhTSH-aided low doses (1.11 GBq and 1.85 GBq) versus high dose (3.7 GBq) of radioiodine in the residual ablation for differentiated thyroid cancer (DTC). METHODS Studies were obtained from computerized searches of MEDLINE, EMBASE, the Cochrane Library (all until September 2012). Randomized controlled trials were included. RESULTS Altogether 1325 patients with DTC participated in seven trials for residual ablation. Overall, studies had a low risk of bias. We found no statistically significant differences between rhTSH and THW treatment in terms of successful ablation rate (OR 0.87, 95% CI 0.56 to 1.37, P=0.56) but significant benefits in health-related quality of life (mean difference 3.59, 95% CI 2.81 to 4.37, P<0.00001), adverse events during and after ablation (OR 0.57, 95% CI 0.44 to 0.73, P<0.00001), radiation exposure to blood and bone marrow (mean difference -0.01, 95% CI -0.02 to -0.01, P<0.00001). In addition, no significant difference was found in the successful ablation rate between the low dose (1.11 GBq and 1.85 GBq) and high dose (3.7 GBq) of radioiodine aided by rhTSH (OR 0.85, 95% CI 0.49 to 1.47, P=0.56). There were no deaths and no serious adverse effects in DTC patients treated with either rhTSH or THW, maximum follow-up was 12 months. None of the included trials investigated secondary malignancies or economic outcomes. CONCLUSION rhTSH is as effective as THW on radioiodine thyroid remnant ablation with significant benefits on health-related quality of life, adverse effects during and after ablation, decreased whole body radiation exposure. The lower radioiodine doses are as effective as high doses for remnant ablation under rhTSH stimulation.

Abstract
The Ribosomal Protein (RP)-HDM2-p53 pathway has been shown to play key roles in oncogene-induced apoptosis and senescence, but the mechanism regulating this pathway remains elusive. The Proline-Rich Akt Substrate of 40 kDA (PRAS40) has recently been identified as a binding partner and inhibitor of the mechanistic Target of Rapamycin Complex 1 (mTORC1). Although other inhibitors of mTORC1 are known tumor suppressors, PRAS40 promotes cell survival and tumorigenesis. Here we demonstrate that Akt- and mTORC1-mediated phosphorylation of PRAS40 at T246 and S221, respectively, promotes nuclear-specific association of PRAS40 with Ribosomal Protein L11 (RPL11). Importantly, silencing of PRAS40 induces upregulation of p53 in a manner dependent upon RPL11. This effect is rescued by wild type PRAS40, but not by the RPL11 binding-null PRAS40 T246A mutant. We find that PRAS40 negatively regulates the RPL11-HDM2-p53 nucleolar stress response pathway and suppresses induction of p53-mediated cellular senescence. This work identifies nuclear PRAS40 as a dual-input signaling checkpoint that links cell growth and proliferation to inhibition of cellular senescence. These findings may help to explain the pro-tumorigenic effect of PRAS40 and identify the PRAS40-RPL11 complex as a promising target for p53-restorative anti-cancer drug discovery.

Abstract
A novel non-contact measurement technique had been developed for the mechanical properties of materials in Split Hopkinson Pressure Bars (SHPB). Instead of the traditional strain gages mounted on the surfaces of bars, two shutters were mounted on the end of bars to directly measure interfacial velocity using Fiber Micro-Displacement Interferometer System for Any Reflector. Using the new technique, the integrated stress-strain responses could be determined. The experimental technique was validated by SHPB test simulation. The technique had been used to investigate the dynamic response of a brittle explosive material. The results showed that the new experimental technique could be applied to the dynamic behavior in SHPB test.

Abstract
OBJECTIVE Tacrolimus is a potent immunosuppressive agent mainly used for allogeneic solid organ transplantation. Although usage of tacrolimus led to a significant increase in short-term allograft survival, the long-term morbidity remains high. Endothelin-1 (ET-1) is reported to be associated with increased vascular resistance, CNI-induced nephrotoxicity and chronic rejection. MATERIALS AND METHODS In the present study, we first detected the serum and renal ET-1 level of rats treated by tacrolimus and found strong positive correlations were existed between the ET-1 level and the tacrolimus dosage and treated time. Furthermore, we studied the protective effect of ambrisentan in liver transplantation rats when co-administrated with tacrolimus. Healthy inbred male Wistar and Sprague-Dawley (SD) rats were used in this study. The post-operative general condition, transplantation survival time, hepatic aminotransferase, serum IFN-γ and level kidney injury biochemical index were recorded and compared to evaluate the immune response and outcomes in the recipient rats after liver transplantation. RESULTS Our results indicate that ambrisentan prevents the changes of ET-1 content in rats of non-operative treatment group and reduced the nephrotoxicity in the rats with liver transplantation. Rats from ambrisentan co-administration group exhibited good postoperative condition and prolonged survival. CONCLUSIONS Ambrisentan reverted some effects induced by tacrolimus in the kidney and indicated a positive potential for therapeutic benefit.

Abstract
We investigated the effects of follicle-stimulating hormone (FSH) on atresia of the dominant follicle and changes in relevant apoptosis genes in granulosa cells of dominant follicles regulated by FSH in vivo. Four-week-old mice were administered FSH by intraperitoneal injection to induce follicular maturation. Granulosa cells of dominant follicles were collected at 48, 72, and 96 h after the first FSH injection. Phosphate-buffered saline was injected as a control. The mRNA levels of relevant granulosa cell apoptosis genes were examined by real-time quantitative polymerase chain reaction, and apoptosis of granulosa cells in dominant ovarian follicles was determined by the terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay. Apoptosis in granulosa cells of dominant follicles was almost TUNEL-negative at 48, 72-66, 72, and 96-90 h after the first FSH injection, but granulosa cell apoptosis in dominant follicles was clearly detected at 96, 102, and 102-96 h by TUNEL. The BIM, caspase-3, and caspase-9 mRNA expression levels were significantly lower after FSH treatment at 72-66 and 96-90 h, compared with that at 72 and 96 h (P < 0.05). Caspase-8 and FasL mRNA expressions did not respond to FSH. FSH rescued granulosa cells from apoptosis when the relevant apoptosis genes were upregulated in early atretic follicles. FSH did not rescue granulosa cells from apoptosis if the DNA was cut into fragments by endonucleases. Thus, the rescue by FSH of granulosa cells from apoptosis and dominant follicle atresia may be accomplished by inhibition of apoptosis in mitochondria.

Abstract
OBJECTIVES There has been increasing interest in mesenchymal stem cells (MSCs) because of their potential use for regenerative therapy; however, there is no well-defined protocol for MSCs culture. This study compares techniques of conventional plate and microcarrier culturing of MSCs. METHODS AND RESULTS Here, different conditions for isolation and expansion of rat MSCs have been examined and it was found that plating density and plating time in primary culture played important roles for culture of these rat MSCs. When plated at 10(8) /cm(2) density for 72 h, in primary culture, recycling stem cells (RS cells) predominated, and characteristics of rat MSCs (including morphology, growth rate, phenotype and differentiation potentials) remained stable during expansion until passage 14. For subculture of the cells, it was found that their growth rate when incubated at 33 °C was higher than those incubated at 37 °C, and maximal increase was 10- and 6-fold respectively. When cultured using microcarriers, at a density of 1 × 10(5) /mg beads, growth kinetics, phenotype and differentiation potentials also remained constant for cells between passage 2nd and 14th; their maximal number increased 16-fold. CONCLUSIONS Compared to conventional plate culture, culture using gelatine porous microcarrier Cultispher-S was superior for large-scale production of rat MSCs.

Abstract
Although imatinib has demonstrated a potent effect on advanced gastrointestinal stromal tumors (GISTs) and has improved the survival of GIST patients, with its prolonged use imatinib resistance is becoming an increasing clinical problem. Mechanisms of secondary resistance are still under investigation. Our study aimed to determine the mechanism of acquired resistance to imatinib in GISTs. Using bidirectional PCR DNA sequencing, we sequenced exons 9, 11, 13 and 17 of the KIT gene and exons 12 and 18 of the PDGFRA gene in secondary resistant lesions obtained from 18 GIST patients after treatment with imatinib. Fourteen of 18 cases carried activating mutations in the KIT gene, with a mutation encoding the juxtamembrane domain present in exon 11 in 12 cases, in exon 13 in 1 case, and in exon 9 in 1 case. In 4 of 10 imatinib-resistant patients, an identical novel missense mutation (T2467G) was found in exon 17, resulting in a substitution of tyrosine by aspartic acid at codon 823 (Y823D). In conclusion, the exon 17 missense mutation T2467G in the tyrosine kinase domain of the KIT gene is correlated with imatinib resistance.

Abstract
Glucagon-like peptide 1 (GLP1) receptor plays a critical role in mediating the biological actions of GLP1 in mammals and fish; however, the gene structure, expression, and functionality of GLP1 receptor (GLP1R) remain largely unknown in birds. In this study, the full-length cDNA of chicken GLP1R (cGLP1R) was first cloned from brain tissue by reverse transcription PCR. The putative cGLP1R is 459 amino acids in length and shares high amino acid sequence identity with that of human (79%), rat (80%), and Xenopus (75%). Using a pGL3-CRE luciferase reporter system, we found that cGLP1R expressed in Chinese hamster ovary cells could be potently activated by cGLP1 (EC(50), 0.11 nM) but not by other structurally related peptides, indicating that cGLP1R is a functional receptor specific to cGLP1. Interestingly, in addition to identification of the transcript encoding cGLP1R of 459 amino acids, eight transcript variants, which were generated by alternative mRNA splicing and predicted to encode either C-terminally or N-terminally truncated cGLP1Rs, were also identified from chicken brain or testis. In line with this finding, multiple cGLP1R transcripts were detected to be expressed in most chicken tissues examined, including pancreas, gastrointestinal tract, and various brain regions by reverse transcription PCR. Using the dual-luciferase reporter assay system, we further found that the 5'-flanking region of cGLP1R gene displays promoter activities in cultured HepG2 and HEK293 cells, suggesting that it may control cGLP1R gene transcription in chicken tissues, including nonpancreatic tissues. Taken together, the results from the present study establish a molecular basis to investigate the roles of GLP1 in chickens.

Abstract
The autoimmune regulator (Aire) is a key mediator of the central tolerance for peripheral tissue self-antigen (PTAs) and is involved in the transcriptional control of many antigens in thymic medullary epithelial cells (mTECs). However, the function of Aire in peripheral lymphoid tissues and haematopoietic cells, particularly in monocytes and macrophages, remains poorly understood. We previously found that the expression of Toll-like receptor (TLR) 1, TLR3 and TLR8 was notably upregulated in pEGFPC1/Aire stably transfected RAW264.7 (GFP-Aire/RAW) cells, while the expressions of other TLRs were not significantly changed. The mechanism by which Aire affects TLR1, TLR3 and TLR8 expression is not clear. Interactions with other proteins, such as DNA-dependent protein kinase (DNA-PK), are crucial for regulating the transcriptional activity of Aire. In this study, we found that Aire and DNA-PK catalytic subunit (DNA-PKcs) were co-located in the nucleus of GFP-Aire/RAW cells, and they interact with each other. Small interfering RNA knock-down of DNA-PKcs in these cells decreased the expression of TLR1, TLR3 and TLR8, but no change was observed in pEGFPC1 stably transfected RAW264.7 (GFP/RAW) cells. We did not observe any change in the expressions of other TLRs after DNA-PKcs knock-down in GFP-Aire/RAW or GFP/RAW cells. A similar observation has been made in pEGFPC1/Aire or pEGFPC1 transiently transfected primary peritoneal macrophages. Using a luciferase activity assay, we found the that the transcriptional activity of TLR1, TLR3 and TLR8 promoters was also decreased after knock-down of DNA-PKcs in GFP-Aire/RAW cells. In conclusion, our results suggest that DNA-PKcs may interact with Aire to promote the expression of TLRs in RAW264.7 cells.
