Description of personality traits by Chinese adjectives: A trial on university students

Studies on personality-related Chinese adjectives suggest either a five-factor or seven-factor structure. In the current investigation, we selected a bigger adjective pool of personality-related adjectives, and tested them on the university students in Northern, Southern, Western and Eastern China. In Study 1, we administered the the self-rating scales of the 650 adjectives in 610 subjects. Five factors emerged clearly, and named as "Intelligent", "Emotional", Conscientious", "Unsocial" and "Agreeable". We then selected 20 adjectives with highest target loadings for each factor to develop a short version of the self-report rating scales, the Chinese Adjective Descriptors of Personality (CADP). In study 2, we administered the 100-adjective CADP to 720 university students in the four areas of China. Again, five-factor structures were confirmed. Loadings of the individual adjectives on the target factor were satisfactory, and the internal alphas for each personality scale were high. Most CADP scales were intercorrelated. There were, however, no significant gender differences in regard to CADP scales. The five-factor structures found in our report were comparable to the Openness to Experiences (or Intellect), Neuroticism, Conscientiousness, Extraversion and Agreeableness found in other cultures. The normative data of the CADP is presented.

Abstract

Hepatocellular carcinoma (HCC) is the sixth most common malignancy worldwide and the third most common cause of death from cancer, after lung and stomach cancer. Hepatitis B virus (HBV) infection is closely related to HCC and is a major cause of HCC. HBV is a lysogenic virus of the hepadnavirus family. Its genome presents a slack, ring-like, double-chain structure, containing four open reading frames. The X region encodes the product HBV X protein (HBx), which is a multifunctional regulatory protein that plays an important role in intracellular signal transduction, viral genome replication and transcription, cell proliferation and apoptosis, cell cycle progression, protein degradation, and genetic stability of hepatocytes. This article summarizes the recent research on the mechanism of promotion of initiation and progression of HCC by HBx protein.

Abstract

The adjacency matrix of a graph is a matrix which represents adjacent relation between the vertices of the graph. Its minimum eigenvalue is defined as the least eigenvalue of the graph. Let Gn be the set of the graphs of order n, whose complements are connected and have pendent paths. This paper investigates the least eigenvalue of the graphs and characterizes the unique graph which has the minimum least eigenvalue in Gn.

Males of D. vorticipennis Puthz, 2005 and D. depressifrons Puthz, 2016 and the female of D. rimosipennis Puthz, 2005 are discovered for the first time. New distributional records are reported for D. cruentatus L. Benick, 1942 and D. depressifrons Puthz, 2016. A key to species of the Dianous luteoguttatus complex is provided.

Abstract

Objective To study the mutual relationship between anti-HBx and IL-10, IL-12 or soluble Fas (sFas) in sera of patients with chronic HBV infection and to explore the importance of anti-HBx detection as well as its role in the development of chronic HBV infection.

Methods Total of 90 cases with chronic HBV infection were randomly selected, including 10 of asymptomatic carriers (ASC), 28 of chronic hepatitis B (CHB), 26 of liver cirrhosis (LC) and 26 patients of hepatocellular carcinoma (HCC). Their clinical data and blood samples were collected, and serum was prepared and stored at -73℃. Anti-HBx was detected with an indirect ELISA established in our earlier research, and levels of IL-10, IL-12 and Fas were determined with commercial double-antibody sandwich ELISA kits. The mutual relationship between anti-HBx and IL-10, IL-12 or sFas in serum were analyzed with the software SPSS 20.0.

Results All levels of IL-10, IL-12 and sFas in peripheral blood showed a rising trend with development of chronic HBV infection. The levels of IL-10 in ASC, CHB, LC and HCC groups were 13.93 ± 14.40 ng/L, 39.38 ± 20.77 ng/L, 69.06 ± 46.37 ng/L and 62.82 ± 23.42 ng/L, respectively, levels of IL-12 in the 4 groups were 15.64 ± 23.04 ng/L, 68.50 ± 23.14 ng/L, 76.83 ± 12.82 ng/L and 83.74 ± 24.88 ng/L, respectively, and levels of sFas were 58.17 ± 77.42 ng/L, 179.88 ± 104.36 ng/L, 249.22 ± 107.80 ng/L and 252.98 ± 87.65 ng/L, respectively. Twenty-seven out of 90 patients showed a positive result for anti-HBx detection, including 1 in ASC, 4 in CHB, 12 in LC and 10 in HCC group. The levels of IL-10, IL-12 and sFas were higher in anti-HBx positive group than in negative group. Statistical analysis demonstrated significant differences of IL-10 and IL-12 between the two groups (P < 0.05), but the differences of sFas had no statistical significance (P = 0.094).

Conclusions Anti-HBx antibody is not protective, and is closely related to IL-10, IL-12 and sFas. It may be an important serum indicator for aggravation from chronic hepatitis B to liver cirrhosis or hepatocellular carcinoma in patients with chronic HBV infection.

Abstract

We report a case of a 78-year-old male was admitted for 2 years of blood CA19-9 >1000 kU/L found at physical examination. Abdominal computed tomography, barium meal and gastrointestinal endoscopy did not find any malignancy. Position emission tomography indicated interstitial pulmonary fibrosis (IPF) (severe) accompanied with reactive hyperplasia of mediastinal lymph node and bilateral pleural thickening. The patient also claimed to have rheumatoid arthritis (RA) for more than 40 years. Then final diagnosis was RA with IPF. The patient’s blood CA19-9 was improved after 5-day treatment of hormone inhalation.

Abstract

A novel zinc porphyrin (5,10,15-tri-dodecoxyphenyl-20-(4-hydroxyphenyl-azo-benzenyl)-porphyrinatozinc (tdhab-ZnP)) with benzenyl-azo-phenolic group, able to adsorb on the nanocrystalline-TiO2 film, has been synthesized. We constructed a dye-sensitized solar cell based on the nanocrystalline-TiO2 hierarchical structure film, with a power conversion efficiency of 4.15 % and a high current density of 14 mA/cm2 under AM 1.5 irradiation. UV-Vis absorption spectra measurements indicated that the tdhab-ZnP molecules formed a charge transfer complex with TiO2 nanoparticles (NPs) through the phenolic group. Cyclic voltammetry measurement showed that the charge separation resulting from the tdhab-ZnP excited singlet state to the conduction band (CB) of TiO2 and charge shifting from the I−/I3− couple to the porphyrin radical cation were thermodynamically feasible.

Abstract

Background

Changes in head and neck anatomy during radiation therapy (RT) produce setup uncertainties of nasopharyngeal cancer (NPC) irradiation. We retrospectively analyzed image guidance data to identify clinical predictors of setup errors.

Patients and methods

The data of 217 NPC patients undergoing definitive RT on a helical tomotherapy (HT) unit were analyzed. Factors including tumor stage, body mass index, weight loss, and planning target volume (PTV) were assessed as predictors of daily megavoltage computed tomography (MVCT) setup displacements, which were automatically registered using software.

Results

Mean daily setup displacements (in mm) were 1.2 ± 0.6, 1.8 ± 0.8, 3.4 ± 1.4 in the medial-lateral (ML), superior-inferior (SI), and anterior-posterior (AP) directions, respectively. Mean weight loss was 4.6 ± 3.3 kg (6.8 ± 4.9%). Patients with weight loss > 5% had significantly larger setup displacements in the AP (3.6 ± 1.5 vs. 2.9 ± 1.1 mm, p < 0.001) and SI (1.6 ± 0.7 vs. 1.9 ± 0.9 mm, p = 0.01) direction, but not in the ML direction (p = 0.279). The AP setup error increased 0.06 mm (y = 0.055x + 2.927, x: percentage of weight loss/PTV, y: AP displacement) per one percent increase in weight loss normalized to PTV.

Conclusions

Patients with weight loss > 5% and smaller PTVs, possibly because of small body frame or neck girth, were more likely to have increased setup errors in the AP direction.

Abstract

The morphology of nanospheres is crucial for designing the nanofabrication in the nanosphere lithography. Here, by plasma etching, the controllable tailoring of the nanosphere is realized and its morphology dependence on the initial shape, microscopic roughness, and the etching conditions is investigated quantitatively. The results show that the shape evolution strongly depends on the etching gas, power, and process duration. Particularly, the aspect ratio (diameter/height) significantly increases with violent etching, turning the spherical shape into tiny ellipsoidal nanoparticles. The findings are practical to the protocol of non-uniform etching of nanoobjects and provide the useful design tool for the device fabrication at nanoscale.
