Correlation between critical thinking disposition and mental self-supporting among nursing undergraduates / 中华行为医学与脑科学杂志

Objective To explore the relationship between critical thinking disposition and mental self-supporting and provide reference for educators in an attempt to improve undergraduate nursing students' positive psychological qualities and critical thinking disposition.Methods A total of 406 nursing undergraduates were investigated by using the California Critical Thinking Disposition Inventory-Chinese Version (CCTDI-CV) and Mental Self-supporting Questionnaire of University students.Results Undergraduate nursing students scored (280.91± 28.43) points averagely in critical thinking disposition,and the dimensions of analyticity (42.17±5.31) and truth seeking(37.56±6.42) got the highest and lowest score respectively.The total score of mental self-supporting was 76.40±8.47 points; among the seven subscales,opening and containing(11.90± 1.72) scored the highest and self-conviction(8.87±2.28) scored the lowest.A positive association was found between critical thinking disposition and mental self-supporting(r=0.583,P＜0.01).The regression analysis showed that students' self-decision,self-cognition,self-confidence and self-charge played a significant role in students' critical thinking disposition (R2=0.435,P＜0.01).Conclusion Undergraduate nursing students' disposition of critical thinking and mental self-supporting were on medium level.The subscales of self-decision,self-cognition,self-confidence and self-charge have huge influence on critical thinking disposition.Nursing educators should make an effort in the above 4 aspects so as to improve undergraduate nursing students' critical thinking disposition.

Phylogeny of Qinghai Plateau Echinococcus g ranulosus isolates inferred by cytochrome oxidase Ⅰ gene sequences / 中国人兽共患病学报

Cystic echinococcosis is one of the most widespread and severe zoonotic helminthic diseases .To understand the phylogeny and genetic polymorphism Echinococcus granulosus (E .granulosus) prevailed in south region of Qinghai Prov-ince ,partial fragment of cytochrome oxidase Ⅰ (COX Ⅰ ) gene sequences were used to infer the phylogenetic relationship of 59 collected samples of E .granulosus in Qinghai Province .Total 72 sequences (13 sequences from GenBank) were aligned using CLUSTAL X ,and then ,Bayesian analyses were performed in Mrbayes-3 .1 .2 .The results revealed that Echinococcus spp .isolates did not form a monophyletic group .The most samples clustered with E . granulosus strain (G1) (AB297617) , but showed high genetic polymorphism .Another three samples clustered with E .multilocularis (AB018440) ,while they showed complex phylogenetic relationships among them ,further indicating that Echinococcus spp .isolates from Qinghai Prov-ince may has a more complex evolutionary history than expected .
