Objective To observe the effect of rehabilitation nursing on activities of daily living (ADL) of patients with stroke in Midway-training Course. Methods 51 stroke patients were divided into control group (n=26) and supervision group (n=25). The control group received routine rehabilitation service, and the supervision group received rehabilitation nursing supervisor in addition. They were assessed with Barthel Index (BI) before and after the course. Results The BI increased after course in both groups (P<0.05), and increased in the supervision group (P<0.05) after 30 d, but not in the control group (P>0.05). Conclusion Rehabilitation nursing during Midway- training Course can improve recovery of the ADL of patients with stroke.

Objective:To evaluate the placental micro-vascular circulation by microvascular flowing imaging (MVFI) method, and to explore the clinical value of microvascular index (MVI) for the diagnosis of fetal growth restriction (FGR).Methods:A total of 21 fetuses at 24-34 weeks of gestation at the Peking Union Medical College Hospital from October to November 2019 were enrolled in this study, including 7 fetal growth restriction (FGR) fetuses, and 14 normal fetuses as control group. The fetuses of the two groups were matched according to the gestational weeks at the ratio of 1∶2. Fetal biometry parameters were measured and the placenta was observed by two-dimensional ultrasound.Uterine artery pulse index (UtA-PI), middle cerebral artery pulse index (MCA-PI), and umbilical artery S/D ratio were evaluated by color and pulse-wave Doppler. The placenta mico-circulation was displayed by the MVFI method and MVI was measured.Results:The study included 14 normal fetuses and 7 FGR fetuses. Compared with the control group, more placenta in the FGR group manifested as thickened and heterogeneous with decreased MVI and increased UtA-PI. There was statistically significant difference in placental mean MVI between two groups ( P=0.044). Besides, a trend towards significant negative correlation was observed between MVI and placenta thickness, although this was not statistically significant ( rs=-0.35, P=0.065). MVI had a higher specificity (100%) in the prediction of FGR. Conclusions:MVFI can display the micro-circulation of the placenta, and provide a direct and quantitative assessment method for placental perfusion.

When facing a sudden danger or aversive condition while engaged in on-going forward motion, animals transiently slow down and make a turn to escape. The neural mechanisms underlying stimulation-induced deceleration in avoidance behavior are largely unknown. Here, we report that in Drosophila larvae, light-induced deceleration was commanded by a continuous neural pathway that included prothoracicotropic hormone neurons, eclosion hormone neurons, and tyrosine decarboxylase 2 motor neurons (the PET pathway). Inhibiting neurons in the PET pathway led to defects in light-avoidance due to insufficient deceleration and head casting. On the other hand, activation of PET pathway neurons specifically caused immediate deceleration in larval locomotion. Our findings reveal a neural substrate for the emergent deceleration response and provide a new understanding of the relationship between behavioral modules in animal avoidance responses.
