实体肿瘤物理和化学微环境异常阻碍了肿瘤与外界进行物质交换,降低了药物渗入肿瘤组织,是肿瘤对放化疗抵抗的重要原因。目前,已有多种针对肿瘤微环境各个组分的治疗方法,如使血管正常化、降低肿瘤间质液压、降解细胞外基质等,以达到增强药物等的渗出,从而增强肿瘤治疗效果。声学调控是改变肿瘤理化微环境的一种有效方法,本文对声学调控其中几个主要的机制和研究进展进行综述,以期为临床肿瘤治疗提供新思路。

Objective To investigate the current status of nurses' knowledge, attitude and behavior to new coronavirus pneumonia, to provide the basis for formulating relevant training strategies. Methods In March 2020, 1 007 clinical nurses in our hospital were selected as the research object. The general information and questionnaire about the new coronavirus pneumonia were investigated in these nurses. Results Scores of 1 007 nurses answered the knowledge, attitude and behavior to new coronavirus pneumonia were(28.82±9.22),(52.04±5.52), and(55.38±7.93), respectively. The total score of knowledge, attitude, and behavior to the new coronavirus pneumonia was(136.24±14.52). The differences of scores of knowledge about new coronavirus pneumonia between different ages, job titles, duties, working years, and when they participated in the training and evaluation of wearing and taking off protective clothing were statistically significant (P<0.05). There was a statistically significant difference in the attitude scores of the new coronavirus pneumonia between different working years and when they participated in training and evaluation of wearing protective clothing (P<0.05). There were statistically significant differences in the behavior scores to new coronavirus pneumonia between whether and when they have participated in the training and evaluation of wearing and taking off protective clothing, and whether they had participated in the training and evaluation of pharyngeal swab collection (P<0.05). Conclusion Nurses' knowledge scores for new coronavirus pneumonia are at a low level, but their attitude and behavior scores are higher. It is recommended that new coronavirus pneumonia knowledge and related training should be strengthened for nurses to improve nurses' knowledge and skills.

Objective To analyze the changes in the use of psychotropic drugs by inpatients in a psychiatric hospital in Guangzhou, and to provide reference for the control, rational application and scientific management of the drugs. Methods The sales amount, frequency of use, and daily use of psychotropic drugs from July 15, 2015 to July 14, 2019 were counted and analyzed. Results There were a total of 40 kinds of psychotropic drugs of 4 types in this hospital. In the past 4 years, the sales of antipsychotic drugs increased first and then decreased, and DDDs increased slightly. The sales amount of atypical antipsychotic drugs accounted for more than 97% of the total drug cost, and DDDs accounted for more than 87%. The sales amount of antidepressants DDDs were increasing year by year, and new generation antidepressants account for more than 99% of the antidepressants. The sales of anti-anxiety drugs increased first and then decreased. The sales of mood stabilizer increased first and then decreased, and DDDs decreased slightly. 65% of psychotropic drug's rank closes to 1. DDDc in 62% of the psychotropic drugs decreased; after abolishing additional cost of drugs, the total sales amount decreased, but the total DDDs increased. Conclusion Abolishing additional cost of drugs had a greater impact on antipsychotic drugs, but little effect for antidepressants, anxiolytics, and mood stabilizers, which may greatly reduces patient's drug cost and promote rational use of drugs.
