Objective To investigate the impulsive traits and their influencing factors in different types of male inmates. Methods A total of 1 206 male inmates in Jiangsu province were assessed by a self-designed questionnaire of detailed criminal records,demographic data,history of substance use and Barratt Impulsiveness Scale (BIS-11).Results ①Significant differences were found between the distribution of age (F＝30.092),educational level(χ2＝84.479),marital status(χ2＝54.386),household registration(χ2＝34.959),smoking history (χ2＝19.047)and drug use history( χ2＝563.144) of male inmates( all P＜0.01).②Difference of impulsivity was found between different types of male inmates,and scores of the impulsivity of the property inmates (total impulsivity (55.92±8.39),attentional impulsiveness (12.70±2.35),motor im-pulsiveness (18.50± 3.88),non-planning impulsivity ( 24.72 ± 4.91)) were significantly lower than other crime types (P＜0.05).③Drug use history had a positive predictive effect on impulsivity of male violent in-mates (B＝4.317,P＜0.01),and educational level(B＝－3.280,P＜0.001),age(B＝－0.094,P＜0.05)and drug use history ( B＝ 3.491, P＜ 0.05 ) had a predictive effect on impulsivity of male property inmates. Conclusion The impulsivity of male property inmates is significantly lower than others and the influence factors of impulsivity among male inmates are age,educational level and drug use history.

Microalgae are a group of photosynthetic microorganisms, which have the general characteristics of plants such as photosynthesis, and some species have the ability of movement which resembles animals. Recently, it was reported that microalgae cells can be engineered to precisely deliver medicine-particles and other goods in microfluidic chips. These studies showed great application potential in biomedical treatment and pharmacodynamic analysis, which have become one of the current research hotspots. However, these developments have been rarely reviewed. Here, we summarized the advances in manageable movement exemplified by a model microalgae Chlamydomonas reinhardtii based on its characteristics of chemotaxis, phototaxis, and magnetotaxis. The bottlenecks and prospects in the application of microalgae-based tactic movement were also discussed. This review might be useful for rational design and modification of microalgal manageable movement to achieve targeted transport in medical and other fields.
