Using a set of panel data of 11,324 firms in China from 1996 to 1999, the paper finds that positive technology spillovers from FIEs to domestic firms occur through tangible assets rather than intangible assets, through domestically consumed products rather than exported products, through ‘traditional’ products rather than new products, and through FIEs employing unskilled workers rather than FIEs employing skilled workers. FIEs are found to generate negative spillovers through exports and through employment of skilled workers.

ObjectiveTo define potential factors that could predict concomitant neoplastic diseases in patients diagnosed with PM/DM, which could inform screening decisions.MethodsTwo researchers independently reviewed articles from Pubmed (MEDLINE), EMBASE, Cochrane Plus Library and ISI Web of Knowledge with no restrictions on study design or language. Given that some of the studies combined PM and DM patients as research subjects while others included only DM patients, data were subjected to meta-analyses for all combined PM/DM studies and studies that included only DM patients to obtain informative results.ResultsFor PM/DM patients, the following factors are all associated with an increased risk of malignancy: older age, age greater than 45, male sex, dysphagia, cutaneous necrosis, cutaneous vasculitis, rapid onset of myostis (<4 weeks), elevated CK, higher ESR, higher CRP levels. Several factors were associated with lower-than-average risk, including the presence of ILD, arthritis/arthralgia, Raynaud's syndrome, or anti-Jo-1 antibody. For DM patients, results indicated an increased risk of malignancy with older age, male sex, the presence of cutaneous necrosis, elevated ESR (>35 mm/hr), higher CRP levels, or anti-p155 antibody. In addition, the presence of anti-ENA antibodies seem to be related to reduced risk of malignancy.ConclusionAwareness and implementation of early-stage cancer screening in PM/DM patients who have these identified factors – such as being older than 45, male sex, cutaneous necrosis, cutaneous vasculitis – are of crucial importance from public health and clinical perspectives and provide insight into the etiopathogenesis of CAM.

Objective The abnormal formation and insufficient clearance of neutrophil extracellular traps (NETs) has been reported to be involved in the pathogenesis of lupus nephritis (LN). The abnormal regulation of NETs may contribute to increases in the levels of circulating cell-free DNA (cfDNA). The present study tested the hypothesis that elevated plasma cfDNA levels are related to LN. Methods Fifty-four systemic lupus erythematosus (SLE) patients and 43 control subjects were included in this study. The cfDNA concentrations were measured using the Picogreen Kit, the low-density granulocyte (LDG) percentage in peripheral blood mononuclear cells (PBMCs) was tested using a flow cytometer and the DNase I activity was measured according to the radial enzyme-diffusion method. Results The mean cfDNA concentration in the SLE group was 236.66±40.09 ng/mL, which was significantly higher than that observed in the healthy control group (187.96±40.55 ng/mL, p<0.0001). Meanwhile, the mean cfDNA concentration in the patients with LN was significantly higher than that observed in the patients without LN (247.27±46.79 ng/mL vs. 213.56±31.34 ng/mL, p=0.0094), and the mean cfDNA concentration in the patients with active LN was significantly higher than that observed in the patients with inactive LN (254.22±50.16 ng/mL vs. 215.93±29.10 ng/mL, p=0.0349). In the SLE group, the cfDNA concentration was to positively correlate with the quantitative 24-hour urinary protein (r=0.350, p=0.013), LDG (r=0.6361, p=0.0019) and neutrophil (r=0.5990, p<0.0001) levels and inversely correlate with the albumin level (r= -0.500, p<0.0001) and endogenous creatinine clearance rate (r=-0.354, p=0.044). Compared to that observed in the control group, the SLE group exhibited a significantly increased percentage of LDGs in PBMCs and a significantly decreased DNase I activity. Conclusion Our data indicate that elevated plasma cfDNA concentrations may be associated with active LN and partially attributed to the abnormal regulation of NETs in SLE patients, thus suggesting that NETs constitute an intrinsic link between cfDNA and active LN.

SummaryDermatomyositis (DM) and polymyosits (PM) are systemic autoimmune diseases whose pathogeneses remain unclear. Neutrophil extracellular traps (NETs) are reputed to play an important role in the pathogenesis of autoimmune diseases. This study tests the hypothesis that NETs may be pathogenic in DM/PM. Plasma samples from 97 DM/PM patients (72 DM, 25 PM) and 54 healthy controls were tested for the capacities to induce and degrade NETs. Plasma DNase I activity was tested to further explore possible reasons for the incomplete degradation of NETs. Results from 35 DM patients and seven PM patients with interstitial lung disease (ILD) were compared with results from DM/PM patients without ILD. Compared with control subjects, DM/PM patients exhibited a significantly enhanced capacity for inducing NETs, which was supported by elevated levels of plasma LL-37 and circulating cell-free DNA (cfDNA) in DM/PM. NETs degradation and DNase I activity were also decreased significantly in DM/PM patients and were correlated positively. Moreover, DM/PM patients with ILD exhibited the lowest NETs degradation in vitro due to the decrease in DNase I activity. DNase I activity in patients with anti-Jo-1 antibodies was significantly lower than in patients without. Glucocorticoid therapy seems to improve DNase I activity. Our findings demonstrate that excessively formed NETs cannot be degraded completely because of decreased DNase I activity in DM/PM patients, especially in patients with ILD, suggesting that abnormal regulation of NETs may be involved in the pathogenesis of DM/PM and could be one of the factors that initiate and aggravate ILD.

Faced with intensified global education competition, universities and other Higher Education institutions are implementing Total Quality Management (TQM) to keep rivals at bay. Meanwhile, research interest in TQM in Higher Education is growing. This paper reviews the achievements and limitations of extant research on TQM in Higher Education, and discusses directions for future research. The paper finds that extant research focuses on (1) teaching and learning but neglects research and industry engagement; (2) an isolated factor (e.g., teacher) but neglects other factors (e.g., facilities); (3) the Higher Education sector in advanced countries but neglects the Higher Education sector in developing countries; and (4) TQM as a phenomenon but neglects theory development and integration. Future research needs to address these limitations, adopt a more holistic perspective, and take a more inclusive and comprehensive approach to TQM in the Higher Education sector.
