Consumer financial education and risky financial asset holding in China
Risky financial asset holding is arguably a desirable financial behaviour that contributes to consumer financial well‐being. However, studies about associations between consumer financial education and risky financial asset holding in China remain limited. To fill this gap, using data from the 2015 China Household Finance Survey, this study examined the association between financial education and risky financial asset holdings and explored its mediators. Results from Probit regressions showed that financial education was positively associated with the household risky financial asset holding. Further analyses based on the mediating model found that financial literacy, economic and financial information search and risk tolerance were mediating factors in the association between financial education and risky financial asset holding. The results have policy implications for improving consumer financial education and financial market participation
Ecological model to predict potential habitats of Oncomelania hupensis, the intermediate host of Schistosoma japonicum in the mountainous regions, China
Schistosomiasis japonica is a parasitic disease that remains endemic in seven provinces in the People's Republic of China (P.R. China). One of the most important measures in the process of schistosomiasis elimination in P.R. China is control of Oncomelania hupensis, the unique intermediate host snail of Schistosoma japonicum. Compared with plains/swamp and lake regions, the hilly/mountainous regions of schistosomiasis endemic areas are more complicated, which makes the snail survey difficult to conduct precisely and efficiently. There is a pressing call to identify the snail habitats of mountainous regions in an efficient and cost-effective manner.; Twelve out of 56 administrative villages distributed with O. hupensis in Eryuan, Yunnan Province, were randomly selected to set up the ecological model. Thirty out of the rest of 78 villages (villages selected for building model were excluded from the villages for validation) in Eryuan and 30 out of 89 villages in Midu, Yunnan Province were selected via a chessboard method for model validation, respectively. Nine-year-average Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) as well as Digital Elevation Model (DEM) covering Eryuan and Midu were extracted from MODIS and ASTER satellite images, respectively. Slope, elevation and the distance from every village to its nearest stream were derived from DEM. Suitable survival environment conditions for snails were defined by comparing historical snail presence data and remote sensing derived images. According to the suitable conditions for snails, environment factors, i.e. NDVI, LST, elevation, slope and the distance from every village to its nearest stream, were integrated into an ecological niche model to predict O. hupensis potential habitats in Eryuan and Midu. The evaluation of the model was assessed by comparing the model prediction and field investigation. Then, the consistency rate of model validation was calculated in Eryuan and Midu Counties, respectively. The final ecological niche model for potential O. hupensis habitats prediction comprised the following environmental factors, namely: NDVI (≥ 0.446), LST (≥ 22.70°C), elevation (≤ 2,300 m), slope (≤ 11°) and the distance to nearest stream (≤ 1,000 m). The potential O. hupensis habitats in Eryuan distributed in the Lancang River basin and O. hupensis in Midu shows a trend of clustering in the north and spotty distribution in the south. The consistency rates of the ecological niche model in Eryuan and Midu were 76.67% and 83.33%, respectively.; The ecological niche model integrated with NDVI, LST, elevation, slope and distance from every village to its nearest stream adequately predicted the snail habitats in the mountainous regions
Mental disorder or conscious disturbance in epidermal growth factor receptor-tyrosine kinase inhibitor treatment of advanced lung adenocarcinoma
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are currently recommended by international guidelines as first-line treatment in patients with advanced EGFR-mutant non-small-cell lung cancer. With the availability of drugs, more and more patients choose EGFR-TKI treatment. However, pharmaceutical drugs used in clinical practice have side effects, such as diarrhea, paronychia, and hepatotoxicity. Mental or conscious disturbance has never been reported before. In our clinical center, we found that several patients with advanced lung adenocarcinoma developed a mental disorder or conscious disturbance after EGFR-TKI treatment. This situation has not previously been reported. We conducted a retrospective study of patients with advanced lung adenocarcinoma treated with EGFR-TKI who showed a mental disorder or conscious disturbance. We reported five cases of lung adenocarcinoma who developed a mental disorder or conscious disturbance after treatment with EGFR-TKI. The main clinical symptoms of these patients were sluggishness, memory deterioration, cognitive disorder, and even hallucination. Brain magnetic resonance imaging showed increased ischemic foci and lacunar infarction, worse encephalatrophy, and demyelination after EGFR-TKI therapy. These psychiatric symptoms did not improve but worsened after taking antipsychotic drugs, suggesting that they were irreversible. The neuropsychiatric symptoms in EGFR-TKI treatment must be considered, and the underlying reason warrants further study
Synthesis and structure of the inclusion complex {NdQ[5]K@Q[10](H₂O)4}·4NO₃·20H₂O
Heating a mixture of Nd(NO₃)₃·6H₂O, KCl, Q[10] and Q[5] in HCl for 10 min affords the inclusion complex {NdQ[5]K@Q[10](H₂O)₄}·4NO₃·20H₂O. The structure of the inclusion complex has been investigated by single crystal X-ray diffraction and by X-ray Photoelectron spectroscopy (XPS)
Non-classical non-Gaussian state of a mechanical resonator via selectively incoherent damping in three-mode optomechanical systems
We theoretically propose a scheme for the generation of a non-classical
single-mode motional state of a mechanical resonator (MR) in the three-mode
optomechanical systems, in which two optical modes of the cavities are linearly
coupled to each other and one mechanical mode of the MR is optomechanically
coupled to the two optical modes with the same coupling strength
simultaneously. One cavity is driven by a coherent laser light. By properly
tuning the frequency of the weak driving field, we obtain engineered
Liouvillian superoperator via engineering the selective interaction Hamiltonian
confined to the Fock subspaces. In this case, the motional state of the MR can
be prepared into a non-Gaussian state, which possesses the sub-Poisson
statistics although its Wigner function is positive.Comment: 6 pages, 5 figure
Anti-TNF-α Therapies in Systemic Lupus Erythematosus
Tumor necrosis factor (TNF)-α is not just a proinflammatory cytokine. It has also been proposed to be an immunoregulatory molecule that can alter the balance of T regulatory cells. Anti-TNF-α therapies have been provided clinical benefit to many patients and introduced for treating moderate to severe rheumatoid arthritis, Crohn's disease, and other chronic inflammatory disorders. However, their use also is accompanied by new or aggravated forms of autoimmunity, such as formation of autoantibodies, including antinuclear antibodies (ANAs), antidouble-stranded DNA (dsDNA) antibodies, and anticardiolipin antibodies (ACL). Systemic lupus erythematosus (SLE) is a disease with autoimmune disturbance and inflammatory damage. The role of TNF-α in human SLE is controversial. Here we review the role of TNF-α in the pathophysiological processes of SLE and the likely effects of blocking TNF-α in treatment of SLE
Associations of Polymorphisms in the Apolipoprotein APOA1-C3-A5 Gene Cluster with Acute Coronary Syndrome
Background. Acute coronary syndromes (ACSs) are clinically cardiovascular events associated with dyslipidemia in common. Single nucleotide polymorphisms (SNPs) and haplotypes in the APOA1/C3/A5 gene cluster are associated with diabetes and familial combined hyperlipidaemia (FCH). Little is known about whether the polymorphisms in these genes affect lipid homeostasis in patients with ACSs. The present paper aimed to examine these associations with 4 SNPs in the APOA1 −75G > A, the APOC3 −455T > C, and APOA5 −1131T > C, c.553G > T variant to ACSs in Chinese Han. Methods. Chinese Han of 229 patients with ACSs and 254 unrelated controls were analyzed. Four SNPs in APOA1/C3/A5 cluster were genotyped and lipid was determined. Results. Our data show that minor allelic frequencies of APOC3 −455T > C, APOA5 −1131T > C, and c.553G > T polymorphisms in patients with ACSs were significantly higher than control group (P < 0.05). Furthermore, the 3 polymorphic sites were strongly of linkage disequilibrium, and minor alleles of 3 SNP sites had higher TG level than wild alleles (P < 0.05), APOC3 −455C and APOA5 c.553T allele carriers also had lower level of HDL-C.
Conclusions. The minor alleles of APOC3 −455T > C, APOA5 −1131T > C, and c.553G > T polymorphisms are closely associated with ACSs
