In contrast to private interest litigation,public interest litigation provides a more potent solution to personal information infringements marked by extensive scope,unspecified victims,and limited individual loss.However,com⁃pensatory damages remain a contentious issue,both in theory and in practice,within the legal framework of personal in⁃formation public interest litigation.Through an empirical study conducted within China's judicial practice,this paper reveals that the pending issue concerning the nature and function of compensatory damages has caused highly contra⁃dictory verdicts regarding their calculation and allocation,as well as their relationship with other forms of pecuniary li⁃abilities.Only by acknowledging the role of compensatory damages imposed in personal information public interest liti⁃gation as"Skimming off Excess Profits",and affirming their function as deterrence rather than compensation can they truly achieve the broader objective of safeguarding personal information security and promoting public welfare,as well as avoid disrupting the harmony of the existing legal landscape. 展开更多

Hofstede and Triands for a long time, seldom receives challenge on its very nature. The authors, however, found at least three critical mistakes in Hofstede's work, and raised their argument that Chinese culture is not a collectivistic one, but a "shi" culture which relies heavily on context. The split of mind is the fundamental cause of this "shi" culture. 展开更多

In the past decade there has been a profusion of studies highlighting covariation between individual differences in stress physiology and behavioural profiles, here called personalities. Such individual differences in ways of coping with stress are relevant both in biomedicine, since different personalities may experience a different stress and disease vulnerability, and in behavioural ecology, since their adaptive value and evolutionary maintenance are the subject of debate. However, the precise way in which individual stress differences and personalities are linked is unclear. Here we provide an updated overview of this covariation across different species and taxa, consider its functional significance and present working hypotheses for how behavioural and physiological responses to stress might be causally linked, affecting life-history traits such as dispersal and life-span [Current Zoology 56 (6): 728-740, 2010]. 展开更多

Cytokines are indispensable signals of the mucosaassociated immune system for maintaining normal gut homeostasis.An imbalance of their profile in favour of inflammation initiation may lead to disease states,such as that is observed in inflammatory bowel diseases(IBD).Although Crohn's disease(CD) is often described as a prototype of T-helper 1-type diseases,and ulcerative colitis(UC) is traditionally viewed as a T-helper 2-mediated condition,the classic paradigm,which categorises cytokines into pro-and anti-inflammatory groups,has recently been changed.The inflammation regulatory pathways may not be mutually exclusive as individual cytokines can have diverse and even opposing functions in various clinical and immunological settings.None the less there are many common immunological responses in IBD that are mediated by cytokines.Although they regulate and influence the development,course and recurrence of the inflammatory process,the concrete pathogenic role of these small signaling molecules is sometimes not unambiguous in the subtypes of the disease.Our aim is to review the current information about pro-and anti-inflammatory effects of traditionally studied and recently discovered cytokines in the pathogenesis of UC and CD.The better understanding of their production and functional activity may lead to the development of new therapeutic modalities. 展开更多

AIM:To clarify the efficiency of the criterion of metabolic syndrome to detecting non-alcoholic fatty liver disease(NAFLD).METHODS:Authors performed a cross-sectional study involving participants of a medical health checkup program including abdominal ultrasonography.This study involved 11 714 apparently healthy Japanese men and women,18 to 83 years of age.NAFLD was defined by abdominal ultrasonography without an alcohol intake of more than 20 g/d,known liver disease,or current use of medication.The revised criteria of the National Cholesterol Education Program Adult Treatment PanelⅢ were used to characterize the metabolic syndrome.RESULTS:NAFLD was detected in 32.2%(95%CI:31.0%-33.5%)of men(n=1874 of 5811)and in 8.7%(95%CI:8.0%-9.5%)of women(n=514 of 5903).Among obese people,the prevalence of NAFLD was as high as 67.3%(95%CI:64.8%-69.7%)in men and 45.8%(95%CI:41.7%-50.0%)in women.Although NAFLD was thought of as being the liver phenotype of metabolic syndrome,the prevalence of the metabolic syndrome among subjects with NAFLD was low both in men and women.66.8%of men and 70.4%of women with NAFLD were not diagnosed with the metabolic syndrome.48.2%of men with NAFLD and 49.8%of women with NAFLD weren't overweight[body mass index(BMI)≥25 kg/m2].In the same way,68.6%of men with NAFLD and 37.9%of women with NAFLD weren't satisfied with abdominal classification(≥90 cm for men and≥80 cm for women).Next,authors defined it as positive at screening for NAFLD when participants satisfied at least one criterion of metabolic syndrome.The sensitivity of the definition"at least 1 criterion"was as good as 84.8%in men and 86.6%in women.Separating subjects by BMI,the sensitivity was higher in obese men and women than in non-obese men and women(92.3%vs 76.8%in men,96.1%vs 77.0%in women,respectively).CONCLUSION:Authors could determine NAFLD effectively in epidemiological study by modifying the usage of the criteria for metabolic syndrome. 展开更多

AIM: To compare the results and complications of early pre-cutting technique with standard technique. METHODS: From January 2003 to December 2004, a total of 426 consecutive therapeutic biliary ERCP procedures were performed by one endoscopist (T.A.). Data were retrospectively collected according to procedure indication and results. Of these, 293 procedures (70.4%) were done with standard technique (group A) and 223 procedures (29.6%) with early pre-cutting technique in case of difficult cannulation (group B). The results and complications of ERCP were compared. RESULTS: Success rate of first attempt cannulation was 98.0% in group A and 87.8% in group 13. The overall incidence of post-ERCP pancreatitis, hemorrhage, perforation and cholangitis was 0%, 0.2%, 0.5% and 0.5%, respectively. Morbidity rate was not significantly different. No procedure-related mortality was occurred. CONCLUSION: For an experienced hand, the early pre-cutting technique for biliary cannulation is safe and effective as standard technique. 展开更多

AIM:To investigate the expression profile of miRNA in esophageal squamous cell carcinoma(ESCC).METHODS:The expression profile of miRNA in ESCC tissues was analyzed by miRNA microarray.The expression levels of miR-143 and miR-145 in 86 ESCC patients were determined by real-time polymerase chain reaction(PCR) using TaqMan assay.The mobility effect was estimated by wound-healing using esophageal carcinoma cells transfected with miRNA expression plasmids.RESULTS:A set of miRNAs was found to be deregulated in the ESCC tissues,and the expression levels of miR-143 and-145 were significantly decreased in most of the ESCC tissues examined.Both miR-143 and miR-145 expression correlated with tumor invasion depth.The transfection of human esophageal carcinoma cells with miR-143 and miR-145 expression plasmids resulted in a greater inhibition of cell mobility,however,the protein level of the previously reported target of miR-145,FSCN1,did not show any significant downregulation.CONCLUSION:These findings suggest that the deregulation of miRNAs plays an important role in the progression of ESCC.Both miR-143 and miR-145 might act as anti-oncomirs common to ESCC. 展开更多

Reasonable income distribution and eradication of rural poverty are vital for building a moderately prosperous society in all respects in China.This paper primarily examines the income distribution and poverty reduction effects of social security spending.Market income and redistribution policies are two determinants of income gaps.Based on CHIP2018 household survey data,we find that inadequate income redistribution policies have contributed to yawning income gaps,and that social security spending is more redistributive than personal income tax and social security contributions.After estimating the redistribution effects of social security spending and itemized incomes,we find that pension payments have contributed the most to household income gaps,and that subsistence protection and rural pension payments help improve income distribution.With respect to the poverty reduction effects of social security spending,we have estimated China’s current poverty incidence and the poverty reduction effects of pension payments,healthcare,and educational allowances with CHIP2018 data,and discover that an increase in social security spending may effectively reduce rural poverty.In building a moderately prosperous society in all respects,China should increase social security spending,focusing on specific target groups,and promote the role of social security spending in regulating income distribution and offering social protection to rural residents. 展开更多

To understand the dynamic characteristics of rockfalls is a prerequisite for disaster prevention and assessment. Models for rockfalls in different forms are established based on the theory of rigid body motion. The equivalent velocity considering the rotational effect is determined by the energy ratio. Besides, considering plastic deformation and nonlinear hardening, the maximum impact force is estimated based on the Hertz contact theory. Then, a case study is carried out to illustrate the applicability of the model and sensitive analyses on some affecting parameters are also made. Calculation results show that the maximum impact force increases with the increasing of incident velocity, angle and slope gradient reflected by the changing of energy ratio. Moreover, the model for the estimation of maximum impact force is validated by two different scales of experiments and compared with other theoretical models. Simulated maximum impact forces agree well with the experiments. 展开更多

Under the planned economy,China’s distribution relations were relations among the state,state-run enterprises,employees and the collective economy;relations between heavy industry and light industry;and relations between cities and the countryside.After China’s transition to a market-oriented economy,the distribution relations among the state,state-run enterprises and employees evolved into distribution relations between the government,enterprises and households;the distribution relations between heavy industry and light industry evolved into distribution relations between the state sector and the private sector;and the distribution relations between cities and the countryside evolved into distribution relations between original urban dwellers and migrant populations.Wage system reform was carried out throughout the transition of these three types of distribution relations.Income distribution contradictions in China,which are a problem left over from history and intrinsic to the market-based economy,eased over the years.Some people and regions achieved prosperity,and urban-rural and interregional income gaps narrowed.However,widening household income gaps pose barriers to China’s economic sustainability and vision of building a moderately prosperous society in all respects.Mechanisms to promote common prosperity are incomplete and inadequate.The disequilibrium of functional distribution is an important cause of these income inequalities.The overall wage level of ordinary workers is low.In the future,China'should give full play to the decisive role of the market in primary distribution to ensure proper return to all types of factors,and enhance redistribution to achieve common prosperity for all its people. 展开更多

With the rapid growth of information and communication technology (ICT), the violation of information privacy has increased in recent years. The privacy concerns now re-emerge right because people perceives a threat from new ICT that are equipped with enhanced capabilities for surveillance, storage, retrieval, and diffusion of personal information. With the trend in the prevalence and the easy use of ICT, it is of necessary to pay much attention to the issue how the ICT can threaten the privacy of individuals on the Internet. While the Email and P2P (Peer-to-Peer) tools are the most popular ICT, this paper aims at understanding their respectively dissemination patterns in spreading of personal private information. To this purpose, this paper using dynamic model technique to simulate the pattern of sensitive or personal private information propagating situation. In this study, an Email propagation model and a Susceptible-lnfected-Removed (SIR) model are proposed to simulate the propagation patterns of Email and P2P network respectively. Knowing their dissemination patterns would be helpful for system designers, ICT manager, corporate IT personnel, educators, policy makers, and legislators to incorporate consciousness of social and ethical information issues into the protection of information privacy. 展开更多

Among pharmaceuticals and personal care products released into the aquatic environment, antibiotics are of particular concern, because of their ubiquity and health effects. Although scientists have recently paid more attention to the threat of antibiotics to coastal ecosystems, researchers have often focused on relatively few antibiotics, because of the absence of suitable analytical methods. We have therefore developed a method for the rapid detection of 36 antibiotic residues in coastal waters, including tetracyclines (TCs), sulfanilamides (SAs), and quinolones (QLs). The method consists of solid-phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis, using electrospray ionization (ESI) in positive mode. The SPE was performed with Oasis HLB and Oasis MCX cartridges. Chromatographic separation on a Cr8 column was achieved using a binary eluent containing methanol and water with 0.1% formic acid. Typical recoveries of the analytes ranged from 67.4% to 109.3% at a fortification level of 100 ng/L. The precision of the method, calculated as relative standard deviation (RSD), was below 14.6% for all the compounds. The limits of detection (LODs) varied from 0.45 pg to 7.97 pg. The method was applied to detemaine the target analytes in coastal waters of the Yellow Sea in Liaoning, China. Among the tested antibiotics, 31 were found in coastal 'waters, with their concentrations between the LOD and 212.5 ng/L. These data indicate that this method is valid for analysis of antibiotics in coastal waters. The study first reports such a large number of antibiotics along the Yellow Sea coast of Liaoning, and should facilitate future comprehensive evaluation of antibiotics in coastal ecosystems 展开更多

AIM:To correlate cyclooxygenase-2(COX-2)expression profile with clinical and pathological variables to assess their prognostic/predictive value in colorectal carcinoma(CRC).METHODS:Archival tumor samples were analyzed using immunohistochemistry for COX-2 expression in 94 patients with CRC.Patients were diagnosed and treatedat the Departments of Surgery and Oncology,King Abdulaziz University Hospital,Saudi Arabia.RESULTS:Fifty-six percent of the tumors showed positive cytoplasmic COX-2 expression,whereas 44%of cases were completely COX-2-negative.There were no significant correlations between COX-2 expression and sex,age,grade or tumor location.However,COX-2 expression revealed a significant correlation with tumor stage(P=0.01)and distant metastasis(P=0.02),and a borderline association with lymph node involvement(P =0.07).Tumors with high COX-2 expression showed a higher recurrence rate than tumors with no expression(P<0.009).In univariate Kaplan-Meier survival analysis,there was a significant(P=0.026)difference in disease-free survival between COX-2-positive and negative tumors in favor of the latter.COX-2 expression did not significantly predict disease-specific survival,which was much shorter for COX-2-positive tumors.In multivariate(COX)models,COX-2 did not appear among the independent predictors of disease-free survival or disease-specific survival.CONCLUSION:COX-2 expression seems to provide useful prognostic information in CRC,while predicting the patients at high risk for recurrent disease. 展开更多
