Abstract
OBJECTIVE As a kind of malignant tumor in the male genitourinary system, prostate cancer exhibits significantly increased occurrence. Prostate-specific antigen (PSA) expression can be seen in the prostate cancer, prostatitis, and other diseases, therefore, lack of diagnostic specificity. The miR-155 expression is abnormally increased in the tumors. Therefore, this study aims to explore the clinical significance of PSA combined miR-155 detection in the early diagnosis of prostate cancer. PATIENTS AND METHODS A total of 86 patients diagnosed with prostate cancer were enrolled in this study. PSA and miR-155 gene expression in tumor tissue were detected by using Real-time PCR. The serum levels of PSA were measured by using enzyme-linked immunosorbent assay (ELISA). The correlation of PSA and miR-155 expression with age, body mass index (BMI), tumor volume, tumor-node-metastasis (TNM) stage, lymph node metastasis (LNM), and other clinicopathological features were analyzed, respectively. RESULTS Serum PSA expression and PSA gene in tumor tissue were significantly higher compared to that in adjacent tissues (p<0.05). PSA gene and protein increased significantly with the clinical stage of TNM and decreased following the increase of grade (p<0.05). The miR-155 level was significantly elevated in the tumor tissue compared with para-carcinoma tissue (p<0.05). PSA and miR-155 expressions were positively correlated with TNM stage, tumor volume, and LNM, and negatively correlated with grade (p<0.05). CONCLUSIONS PSA and miR-155 were closely related to the clinicopathological features of prostate cancer. Combined detection is helpful for the early diagnosis of prostate cancer.

Abstract
In countries with low and moderate incidence of tuberculosis (TB), the disease tends to concentrate in specific high-risk populations such as people with diabetes mellitus (DM). We review the updated evidence on the association between 1) DM and active TB, and 2) DM and latent tuberculous infection (LTBI), and 3) we summarize the findings on the population-level impact of DM on TB epidemiology, with particular focus on low- and moderate-incidence settings. We conducted an updated review of studies on DM and active TB, and found 11 more cohort studies published after the previous systematic review from 2008. The updated pooled relative risk (RR) (2.03, 95%CI 1.62-2.55) of all the studies was substantially lower than the three-fold risk increase in the previous review. Substantial heterogeneity of RR across studies was found. Possible reasons for such heterogeneity include different levels of residual confounding, the effect of modification by age, and different levels of glycemic control in the population. In a recently published systematic review on DM and LTBI, one cohort study and 12 cross-sectional studies were identified. The results from cross-sectional studies suggest a significant but modestly increased risk of LTBI among patients with DM (pooled odds ratio 1.18, 95%CI 1.06-1.30). We reviewed evidence on the population-level impact of DM on TB epidemiology in studies using population-attributable fraction analysis and infectious disease modelling. Those studies revealed that DM accounted for a substantial TB burden in low- and moderate-incidence countries. Finally, we discussed the complex association of obesity, DM and TB risk and the impact of the global obesity pandemic on TB epidemiology.

Abstract
While vorticity defined as the curl of the velocity has been broadly used in fluid and plasma physics, this quantity has been underutilized in space physics due to low time resolution observations. We report Magnetospheric Multiscale (MMS) observations of enhanced electron vorticity in the vicinity of the electron diffusion region of magnetic reconnection. On 11 July 2017 MMS traversed the magnetotail current sheet, observing tailward-to-earthward outflow reversal, current-carrying electron jets in the direction along the electron meandering motion or out-of-plane direction, agyrotropic electron distribution functions, and dissipative signatures. At the edge of the electron jets, the electron vorticity increased with magnitudes greater than the electron gyrofrequency. The out-of-plane velocity shear along distance from the current sheet leads to the enhanced vorticity. This, in turn, contributes to the magnetic field perturbations observed by MMS. These observations indicate that electron vorticity can act as a proxy for delineating the electron diffusion region of magnetic reconnection.

Abstract
Background The inhibitor of apoptosis, B-cell lymphoma 2 (Bcl-2), is encoded by the BCL2 gene. Previous studies have shown that microRNAs are downregulated in prostate cancer. This study aimed to investigate the role of microRNA-205 and microRNA-338-3p and cell apoptosis in prostate carcinoma tissue and the LNCaP human prostate adenocarcinoma cell line by directly targeting the BCL2 gene and Bcl-2 protein expression. Material/Methods Bioinformatics methods predicted the target genes of miR-205 and miR-338-3p, which were validated by a luciferase assay. Immunohistochemistry was used to detect Bcl-2 protein expression in 30 samples of prostate carcinoma tissue and 30 matched samples of normal prostate. The normal prostate epithelial cell line, RWPE-1, and LNCaP human prostate adenocarcinoma cells studied in vitro. BCL2 mRNA expression and Bcl-2 protein expression were determined by quantitative polymerase chain reaction (q-PCR) and Western blot, respectively. Cell apoptosis was measured by flow cytometry using annexin V, fluorescein isothiocyanate, and phycoerythrin (annexin V-FITC/PE). Results TargetScan Human 7.2 predicted that the structures of miR-205 and miR-338-3p had a binding site on the proto-oncogene, BCL2, which was verified by a luciferase assay. The expression of miR-205 and miR-338-3p were significantly downregulated in prostate carcinoma tissues and LNCaP cells when compared with normal controls. BCL2 expression was significantly inhibited by overexpression of miR-205 and miR-338-3p in LNCaP cells. Conclusions The results of this study showed that miR-205 and miR-338-3p downregulated the expression of the BCL2 gene and decreased apoptosis in prostate carcinoma.

Abstract
OBJECTIVES To examine the association of FVI and frailty in Chinese elders. DESIGN A sectional study was conducted in three cities (Shanghai, Zhengzhou, and Baoji) in China from June 2017 to June 2018. PARTICIPANTS A total of 5699 participants from 49 districts were included in the current study by two-stage sampling methods. MEASUREMENTS Frailty was measured by a validated Chinese version of the FRAIL scale. FVI per day was measured by two single questions. RESULTS The sample proportion with sufficient fruit intake was 36.7%, and 44.7% reported sufficient vegetable intake. The sample proportions that were robust, pre-frail, and frail were 43.6%, 38.3%, and 18.1%, respectively. Compared with low FVI, after including covariates, the odds ratio (OR) of frailty was 0.84 (95% CI: 0.73-0.97) for moderate fruit intake and 0.81 (95% CI: 0.70-0.94) for enough fruit intake; the OR of frailty was 0.83 (95% CI: 0.68-0.91) for moderate vegetable intake and 0.77 (95% CI: 0.64-0.93) for enough vegetable intake. CONCLUSION High FVI was negatively associated with the OR of frailty in Chinese elders. This finding implies it is important to promote FVI among adults to prevent frailty.

Responses of leaf C:N:P stoichiometry to water supply in the desert shrub Zygophyllum xanthoxylum. PLANT BIOLOGY (STUTTGART, GERMANY) 2019; 21:82-88.

Abstract
Based on the elemental composition of major biochemical molecules associated with different biological functions, the 'growth rate hypothesis' proposed that organisms with a higher growth rate would be coupled to lower C:N, especially lower C:P and N:P ratios. However, the applicability of the growth rate hypothesis for plants is unclear, especially for shrubs growing under different water supply. We performed an experiment with eight soil moisture levels (soil water content: 4%, 6%, 8%, 13%, 18%, 23%, 26% and 28%) to evaluate the effects of water availability on leaf C:N:P stoichiometry in the shrub Zygophyllum xanthoxylum. We found that leaves grew slowly and favored accumulation of P over C and N under both high and low water supply. Thus, leaf C:P and N:P ratios were unimodally related to soil water content, in parallel with individual leaf area and mass. As a result, there were significant positive correlations between leaf C:P and N:P with leaf growth (u). Our result that slower-growing leaves had lower C:P and N:P ratios does not support the growth rate hypothesis, which predicted a negative association of N:P ratio with growth rate, but it is consistent with recent theoretical derivations of growth-stoichiometry relations in plants, where N:P ratio is predicted to increase with increasing growth for very low growth rates, suggesting leaf growth limitation by C and N rather than P for drought and water saturation.

Abstract
Background Differentially expressed genes (DEGs) of IBC were selected from the Gene Expression Omnibus (GEO) chip data: GSE21422 and GSE21974. Network analysis of the DEGs and IBC-related genes was performed in STRING database to find the core gene. Thus, this study aimed to determine the role of NUSAP1 in invasive breast cancer (IBC) and to investigate its effect on drug susceptibility to epirubicin (E-ADM). Material/Methods The mRNA expression of NUSAP1 was determined by quantitative polymerase chain reaction (q-PCR). The protein expression was detected by Western blotting. Cell growth and growth cycle were detected by MTT assay and flow cytometry, respectively. Cell migration and invasion were tested by Transwell assay. Results Through use of gene network analysis, we found that NUSAP1 interacts with IBC-related genes. NUSAP1 presented high expression in IBC tissue samples and MCF-7 cells. NUSAP1 overexpression promoted the growth, migration, and invasion of MCF-7 cells. While NUSAP1 gene silencing downregulated the expression of genes associated with cell cycle progression in G2/M phase, cyclin D kinase (CDK1) and DLGAP5 arrested cells in G2/M phase and significantly inhibited the growth, migration, and invasion of MCF-7 cells. si-NUSAP1 increased the susceptibility of MCF-7 cells to E-ADM-induced apoptosis. Conclusions Our study provides evidence that downregulation of NUSAP1 can inhibit the proliferation, migration, and invasion of IBC cells by regulating CDK1 and DLGAP5 expression and enhances the drug susceptibility to E-ADM.

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: 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
PURPOSE OF REVIEW The extrinsic risk factors for postoperative cognitive disturbance have been a source of concern during the perioperative period, and these risk factors remain the subject of controversy. This review of recent studies focuses on the effect of these factors on postoperative cognitive disturbance during the perioperative period. RECENT FINDINGS Impairment of cerebral autoregulation may predispose patients to intraoperative cerebral malperfusion, which may subsequently induce postoperative cognitive disturbance. The neurotoxicity of several volatile anesthetics may contribute to cognitive functional decline, and the impact of intravenous anesthesia on cognitive function requires further exploration. Multimodal analgesia may not outperform traditional postoperative analgesia in preventing postoperative delirium. Furthermore, acute pain and chronic pain may exacerbate the cognitive functional decline of patients with preexisting cognitive impairment. The nuclear factor-kappa beta pathway is an important node in the neuroinflammatory network. SUMMARY Several intraoperative factors are associated with postoperative cognitive disturbance. However, if these factors are optimized in perioperative management, postoperative cognitive disturbance will improve.

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
BACKGROUND AND AIMS Dysfunction of GABAergic inhibitory controls contributes to the development of neuropathic pain. We examined our hypotheses that (1) chronic constriction injury (CCI)-induced neuropathic pain is associated with increased spinal GABAergic neuron apoptosis, and (2) hyperbaric oxygen therapy (HBO) alleviates CCI-induced neuropathic pain by inhibiting GABAergic neuron apoptosis. METHODS Male rats were randomized into 3 groups: CCI, CCI+HBO and the control group (SHAM). Mechanical allodynia was tested daily following CCI procedure. HBO rats were treated at 2.4 atmospheres absolute (ATA) for 60min once per day. The rats were euthanized and the spinal cord harvested on day 8 and 14 post-CCI. Detection of GABAergic cells and apoptosis was performed. The percentages of double positive stained cells (NeuN/GABA), cleaved caspase-3 or Cytochrome C in total GABAergic cells or in total NeuN positive cells were calculated. RESULTS HBO significantly alleviated mechanical allodynia. CCI-induced neuropathic pain was associated with significantly increased spinal apoptotic GABA-positive neurons. HBO considerably decreased these spinal apoptotic cells. Cytochrome-C-positive neurons and cleaved caspase-3-positive neurons were also significantly higher in CCI rats. HBO significantly decreased these positive cells. Caspase-3 mRNA was also significantly higher in CCI rats. HBO reduced mRNA expression of caspase-3. CONCLUSIONS CCI-induced neuropathic pain was associated with increased apoptotic GABAergic neurons induced by activation of key proteins of mitochondrial apoptotic pathways in the dorsal horn of the spinal cord. HBO alleviated CCI-induced neuropathic pain and reduced GABAergic neuron apoptosis. The beneficial effect of HBO may be via its inhibitory role in CCI-induced GABAergic neuron apoptosis by suppressing mitochondrial apoptotic pathways in the spinal cord. IMPLICATIONS Increased apoptotic GABAergic neurons induced by activation of key proteins of mitochondrial apoptotic pathways in the dorsal horn of the spinal cord is critical in CCI-induced neuropathic pain. The inhibitory role of HBO in GABAergic neuron apoptosis suppresses ongoing neuropathic pain.

PRAS40 promotes NF-κB transcriptional activity through association with p65. Oncogenesis 2017; 6:e381.

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
Breast cancer is the most common cancer in women worldwide. Local invasion, metastasis, and chemotherapy resistance are the obstacles for treatment of breast cancer. In this study, we aim to investigate the role of miR-144 in breast cancer. We demonstrate that the expression of miR-144 is downregulated in breast cancer and cell lines, and lower miR-144 expression is associated with poor differentiation, higher clinical stage, and lymph node metastasis in patients with breast cancer. The rescue of miR-144 expression is able to inhibit the cell proliferation and the ability of cell migration and invasion. In addition, we show that miR-144 can directly target at 3′-untranslation region of zinc finger E-box-binding homeobox 1 and 2, that is, ZEB1 and ZEB2, and regulate their expression at transcriptional and translational levels. Moreover, we also demonstrate that ectopic expression of miR-144 can inhibit the process of epithelial mesenchymal transition in MCF-7 and MDA-MB-231 cells. Thus, we here demonstrate that miR-144 functions as a tumor suppressor in breast cancer at least partly through inhibiting ZEB1/2-mediated epithelial mesenchymal transition process. Our findings indicate that the miR-144-ZEB1/2 signaling could represent a promising therapeutic target for breast cancer treatment.

Abstract
Prosthetic knee joint (PKJ) is an important apparatus for trans-femoral amputees to regain walking ability. This study has two objectives: (1) to design a high performance and low-cost passive PKJ and (2) to evaluate the performance of the PKJ. In the proposed PKJ design, a four-bar linkage was employed as the mechanical structure, and parallel spring and damper were used as the two connecting rods of the four-bar linkage. With the parallel spring, the length of the connecting rod is variable and a buffer flexion angle can be generated, which was consistent with that of the human knee joint. The damper was used to regulate the swing speed of the shank. Through theoretical analysis, modeling, and simulation, key parameters of the mechanical structure were optimized. Finally, experimental studies were conducted to test the performance of the PKJ, including fatigue test and gait analysis. The results showed that the designed PKJ is reliable and the gait of PKJ is close to the healthy subject. Moreover, it is comfortable and showed no adverse effects on the amputee during the walking experiment.

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.

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.

Short-term administration of the glucagon receptor antagonist LY2409021 lowers blood glucose in healthy people and in those with type 2 diabetes. Diabetes Obes Metab 2015; 17:414-22. [PMID: 25656305 DOI: 10.1111/dom.12446] [Citation(s) in RCA: 78] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2014] [Revised: 01/29/2015] [Accepted: 01/31/2015] [Indexed: 11/30/2022]
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
Astrocyte activation plays a pivotal role in neuroinflammation, which contributes to neuronal damage, so the inhibition of astrocyte activation may alleviate the progression of neurodegeneration. Recent studies have proved that urinary trypsin inhibitor ulinastatin could inhibit NF-kB activation. In our study, the inhibitory effects of ulinastatin on the production of pro-inflammatory mediators were investigated in lipopolysaccharide (LPS)-reduced primary astrocyte. Our results showed that ulinastatin significantly inhibited LPS-induced astrogliosis, which is measured by MTT and BrdU. Ulinastatin decreased the production of pro-inflammatory cytokines, such as TNF-α, IL-6, IL-1β, it significantly decreased both the mRNA and the protein levels of these pro-inflammatory cytokines and also increased the protein levels of IκB-α binded to NF-κB, which blocked NF-κB translocation to the nucleus and prevented its activity. Our results suggest that ulinastatin is able to inhibit neuroinflammation by interfering with NF-κB signaling. The study provides direct evidence of potential therapy methods of ulinastatin for the treatment of neuroinflammatory diseases.
