This study aims to evaluate the clinical effectiveness and safety of suction tubes with markings in mechanically ventilated pediatric patients. Materials and Methods: A randomized assignment was carried out on a cohort of 52 pediatric patients who underwent mechanical ventilation in the Pediatric Intensive Care Unit at the Third Affiliated Hospital of Sun Yat-sen University, covering the period from January 2022 to December 2022. These patients were divided into two groups: an improved group (n = 26) utilizing marked suction tubes, and a regular group (n = 26) employing conventional suction tubes. The objective of our study was to evaluate the clinical effectiveness of marked suction tubes. Results: The effects of the improved group on the vital signs of children undergoing mechanical ventilation were small and statistically significant compared with the regular group (p < 0.05). Additionally, the improved group exhibited a reduced frequency of sputum suction, shorter mechanical ventilation duration, and fewer days of hospitalization in the PICU compared to the regular group during the ventilation period. Notably, the difference in the duration of PICU hospitalization was statistically significant (p < 0.05). Moreover, the incidence of adverse reactions in the improved group was notably lower, with statistically significant differences observed in airway mucous membrane damage and irritating cough when compared to the regular group (p < 0.05). Conclusion: The utilization of marked suction tubes provides clinical nurses with clear guidance for performing suctioning with ease, efficiency and safety. Consequently, advocating for the widespread implementation of marked suction tubes in clinical practice is a commendable pursuit.展开更多

Unmarked item, compared with marked item,is more natural, more neutral, more fundamental, and has higher using frequency and wider distribution. From the perspective of markedness theory, the study, collecting 86 English passives and 85 Chinese passives(including 35 notional passives and 50 Beisentences), contrastively analyzes the unmarkedness of English and Chinese passives from the aspects of patient animacy, emotional color, and tense through example-illustration and description. The analysis shows that the unmarkedness of English and Chinese passives has different expressions in the three aspects. Inanimate patient has stronger unmarkedness in both English and Chinese passives, for it is more frequently-used than animate patient. According to people's cognition and language using habits, the emotional color of English passives and Chinese notional passives is neutral in most cases, so the neutral emotional color is unmarked.But in Chinese Bei-sentences, negative emotional color has stronger unmarkedness. As for the tense expression, English passives have wider distributions in time span and simpler structure than Chinese passives. Thus, English passives possess stronger unmarkedness in the light of tense. According to the analysis, the study proposes feasible advice for second language acquisition and translation.展开更多

The translation of tourist materials thus weighs a lot in the economic development and cross-cultural communication. But the condition is not satisfactory, there are still existing some problems in the translation of tourist publicity materials. Therefor the readers can't receive the equal information that the original text expressed. Based on this fact,the paper attempts to analyze what pragmatic failures there are in the translation of tourist materials and to analyze how the Pragmaticmarkedness Equivalence Principle(PMEP) approach can be applied to the translation of tourist publicity materials to achieve the translation equivalence.展开更多

Few researches have combined the Markedness Theory with literature theories and even no research has been done to study the Feminism Theory from the perspective of the Markedness Theory. This paper discusses markedness theory with regard to two basic issues: Why it is ok to say"历史"in Chinese, but the equivalent in English is"history", not"*herstory". Why the meaning of"governor"and"governess"is distinctively different? No research concerning the issues from the perspective of markedness has been conducted yet. This paper gives a brief review of the studies concerning the Markedness Theory, on the basis of which the question is aroused.展开更多
