Objective To explore the relationship between visuospatial abilities of the students ma-jor in air traffic management and their performances,and then provide theories of their vocational classified. Methods 104 healthy male college students were tested by the cognitive laterality battery (CLB),which included visuospatial tests and verbal-sequential tests.At the same time,their performances assessed by air traffic management stimulators.Results Subjects with higher scores achieved by operating on air traffic management stimulators have higher visuospatial abilities,which was confirmed by the visual spatial scores (A) ((0.183±0.094) vs (0.060±0.338), t=41.57, P=0.000) and cognitive laterality quotient (CLQ) ((0.087±0.108) vs (-0.096±0.101), t=43.14, P=0.000)).However,compared with others in lower scores group,their scores on the phonological tests (P) reduced ((0.096±0.081) vs (0.157±0.092), t=6.81, P=0.012) ) .Moreover,there were the significant positive correlation between their performance on air traffic management stimulators and A ( r=0.749, P<0.01) ,CLQ ( r=0.663, P<0.01) ,cognitive performance quotient (CPQ) ( r=0.394, P<0.01).Conclusion For air traffic management occupation,the higher visual spatial abilities were the base of having the higher performance.Thus the visuospatial abilities may be as a good index of selecting and vocational classified for air traffic management students.

Objective: To design and make a mind map of enterostomy health education and provide a reference for health education of patients with enterostomy. Methods: The mental map group was set up, and the contents of health education for patients with enterostomy were initially established by referring to the literature and combining with the clinical practice. The first draft of mental health education mentality of enterostomy was made by drawing software. After consulting and verifying by experts finalized. Results: The formed intestinal orifice health education mind map consisted of 4 parts of admission education, preoperative education, postoperative education, discharge guidance and small modules contained in each part. Conclusions The mind map is comprehensive and can be used for health education of patients with enterostoma.

Apomixis has been widely concerned because of its great potential in heterosis fixation. Artificial apomixis is an important direction of current apomixis research. Mitosis instead of Meiosis (MIME) produces diploid gametes that is identical with the maternal genetic composition and is a key step in the artificial creation of apomixes. This paper reviews the occurrence of MIME and its application in crop apomixis and the problems encountered, in an aim to provide reference for expanding the application of MIME in crop apomixis.

Transcranial magneto-acoustic electrical stimulation (TMAES) is a novel method of brain nerve regulation and research, which uses induction current generated by the coupling of ultrasound and magnetic field to regulate neural electrical activity in different brain regions. As the second special envoy of nerve signal, calcium plays a key role in nerve signal transmission. In order to investigate the effect of TMAES on prefrontal cortex electrical activity, 15 mice were divided into control group, ultrasound stimulation (TUS) group and TMAES group. The TMAES group received 2.6 W/cm ² and 0.3 T of magnetic induction intensity, the TUS group received only ultrasound stimulation, and the control group received no ultrasound and magnetic field for one week. The calcium ion concentration in the prefrontal cortex of mice was recorded in real time by optical fiber photometric detection technology. The new object recognition experiment was conducted to compare the behavioral differences and the time-frequency distribution of calcium signal in each group. The results showed that the mean value of calcium transient signal in the TMAES group was (4.84 ± 0.11)% within 10 s after the stimulation, which was higher than that in the TUS group (4.40 ± 0.10)% and the control group (4.22 ± 0.08)%, and the waveform of calcium transient signal was slower, suggesting that calcium metabolism was faster. The main energy band of the TMAES group was 0-20 Hz, that of the TUS group was 0-12 Hz and that of the control group was 0-8 Hz. The cognitive index was 0.71 in the TMAES group, 0.63 in the TUS group, and 0.58 in the control group, indicating that both ultrasonic and magneto-acoustic stimulation could improve the cognitive ability of mice, but the effect of the TMAES group was better than that of the TUS group. These results suggest that TMAES can change the calcium homeostasis of prefrontal cortex nerve clusters, regulate the discharge activity of prefrontal nerve clusters, and promote cognitive function. The results of this study provide data support and reference for further exploration of the deep neural mechanism of TMAES.
