The purpose of this study is to explore how consumers process persuasive information from product review videos on social media platforms. We apply the elaboration likelihood model (ELM) to investigate the impacts of the central routes (information quality) and peripheral routes (characteristics of product reviewers and video popularity) on perceived persuasiveness. Additional to this study is examining the consumer involvement as a moderator between central and peripheral routes and perceived persuasiveness. The study sample consisted of 314 respondents from China. The results show that both routes substantially impact consumers' perceptions related to persuasive information and result in intentions of behavior. Moreover, the relationship between video popularity and perceived persuasiveness is positively moderated by consumer involvement. Our findings not only help the scholars understand the persuasive process in product review videos, but also assist the marketers and product reviewers in developing a better product marketing strategy on social media platforms.
A comparative study on Chinese batik of Miao and Buyi in GuiZhouSheng

The purpose of this study is to comparatively examine techniques and expressive characteristics of batik by focusing on the work of DanZhai and that of ZhenNing Buyi. We collected 50 pieces of batik each from Miao and Buyi in Chinese GuiZhouSheng and then analyzed their colors and patterns. The findings show that most of Miao’s batik had deep and soft tones, while that of Buyi most often had blackish tone since the number of dyes in the latter is higher than that in the former. Miao often used patterns expressing animals or animals and plants, while Buyi frequently used geometric ones. An examination of specific motifs demonstrated that butterflies, fish, and flowers were most often used by Miao, while dots, vortexes, lines, and lozenges were frequently utilized by Buyi. For expressive techniques, both Miao and Buyi commonly used simple stylized expression or complex expression combining stylized and geometric techniques. Maio’s motifs were often decoratively expressed with delicate curves, while Buyi’s motifs had simple structures, so pictures were neatly expressed with thick lines and wide and simple planes. For the composition of the motifs, incomplete symmetry between top and bottom and between left and right often appeared in Maio, while in Buyi complete symmetry was frequently shown.
In Vitro and In Vivo Evaluation of Ranitidine Hydrochloride Loaded Hollow Microspheres in Rabbits
Yu-meng Wei,Ling Zhao 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.10
The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery systems with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride (RH) were prepared by a novel solvent diffusion-evaporation method using ethyl cellulose (EC) dissolved in a mixture of ethanol and ether (6:1.0, v/v). The yield and drug loading amount of hollow microspheres were 83.21±0.28% and 20.71±0.32%, respectively. The in vitro release profiles showed that the drug release rate decreased with increasing viscosity of EC and the diameter of hollow microspheres, while increased with the increase of RH/EC weight ratio. Hollow microspheres could prolong drug release time (approximately 24 h) and float over the simulate gastric fluid for more than 24 h. Pharmacokinetic analysis showed that the bioavailability from RH-hollow microspheres alone was about 3.0-times that of common RH gelatin capsules, and it was about 2.8-times that of the solid microspheres. These results demonstrated that RH hollow microspheres were capable of sustained delivery of the drug for longer period with increased bioavailability.
Genetic and phylogenetic analysis of the honey bee sacbrood virus from jiangxi isolates

The high prevalence of honeybee viral diseases poses a severe threat to the health of honeybees and causes substantial economic losses worldwide. Sacbrood virus (SBV) is a single-strand RNA virus that infects honeybees at all life stages. The infection can shorten the lifespan of adult bees and is lethal to larvae. SBV is the major cause of honeybee losses in Asia. Genetic and phylogenetic analyses of SBV isolates from different areas have been previously conducted. However, the impact of Apis mellifera Linnaeus and Apis cerana Fabricius coexistence on the infection and phylogeny of SBV remains unknown. In this study, we collected A. cerana and A. mellifera samples from commercial apiaries, only A. cerana in mountainous region. SBV prevalence was evaluated in three commercial apiaries of Jinxi, Tonggu and Nanchang and two mountainous regions of Zixi and Yifeng. In our sampling location, we found a higher SBV prevalence in the mountainous regions than in commercial apiaries. Partial structural polyprotein coding sequences were sequenced and compared with other GenBank SBV isolates. Phylogenetic tree topologies showed that SBV isolates form two major groups based on their host specificity, and isolates from same country tend to cluster together in subclades, indicating that the host and geographic region has significant effects on SBV strain specificity.

Objective: To investigate the correlation between extracellular matrix protein-1 (ECM1) and the growth, metastasis and angiogenesis of laryngeal carcinoma. Materials and Methods: Forty-five samples with laryngeal benign and malignant tumors confirmed by pathology in Laiwu City People's Hospital from March 2006 to March 2011 were collected, in which there were 29 cases with laryngeal carcinoma and 16 with benign tumors. The expression of ECM1 and factor VIII-related antigens in patients with laryngeal carcinoma and those with benign tumors was respectively detected using immunohistochemical method, and the correlation between ECM1 staining grade and microvessel density (MVD) was analyzed. Results: In laryngeal carcinoma tissue, ECM1 was mainly expressed in cytoplasm, less in cytomembrane or intercellular substance. With abundant expression in the tissue of laryngeal benign tumors (benign mesenchymoma and hemangioma), ECM1 was primarily expressed in the connective tissue, which was different from the expression in laryngeal carcinoma tissue. The proportion of positive ECM1 staining (++) in patients with laryngeal carcinoma was dramatically higher than those with benign tumors (p<0.05), and that of strongly-positive ECM1 staining (+++) slightly higher. The results of Spearman nonparametric correlation analysis revealed that ECM1 staining grade in laryngeal carcinoma tissue had a significantly-positive correlation with MVD (r=0.866, p=0.000). Conclusions: ECM1 expression in laryngeal carcinoma is closely associated with tumor cell growth, metastasis and angiogenesis, which can be considered as an effective predictor in the occurrence and postoperative recurrence of laryngeal carcinoma.
