Objective To explore the relationship between embryo damage and anxiety,depression and life events during pregnancy. Methods A case control study was carried out. 192 women diagnosed with embryo damage were selected as the case group,and 192 normal pregnant women or normal parturition within 7 days were selected as the control group from March to June,2014.All cases were from two 3-A-grade general hospitals of Jining. Self-rating anxiety scale ( SAS ) , center for epidemiological survey, depression scale( CES-D) and life events scale for pregnant women( LESPW) were used to evaluate the anxiety,depres-sion and life events of the two groups,so as to analyze the association between these factors and embryo dam-age. Results Multiple non-conditional logistic regression analysis showed that anxiety ( β=0. 409, OR=1.050,95%CI =1.003-1.009) ,depression( β=0.085, OR=1.088,95%CI =1.035-1.145) ,life events dur-ing pregnancy( β=0.003, OR=1.003,95%CI =1.001-1.005) were the risk factors of embryo damage,while education ( β=-0.749, OR=0.452,95%CI=0.298-0.685) ,pre pregnancy health status ( β=-1.366, OR=0.255,95%CI =0.098-0.655) and taking the initiative to acquire knowledge of eugenics ( β=-0.884, OR=0.413,95%CI =0.203-0.840) were the protective factors of embryo damage. Conclusion Anxiety,depres-sion and life events during pregnancy are related to the occurrence of embryo damage. High degree of educa-tion,pre pregnancy in good health and taking the initiative to acquire eugenics knowledge can reduce the oc-currence of embryo damage.

Objective To explore the effect of robotic training under position limitation on upper limb of patients with shoulder sub-luxation after stroke. Methods From March to December,2023,sixty patients with shoulder subluxation after stroke in the First Affiliated Hospital of Bengbu Medical University were randomized into conventional group(n = 20),robot group(n = 20)and position-limited group(n = 20).All the groups accepted conventional rehabilitation,while the robot group underwent robot training and the position-limited group underwent robot training under position limitation,for four weeks.Before and after treatment,Fugl-Meyer Assessment-Upper Extremities(FMA-UE)and modified Bar-thel Index(MBI)were used for evaluation,surface electromyography(sEMG)was used to measure the average electromyography(AEMG)and root mean square(RMS)of posterior deltoid fasciculus and supraspinatus during contraction,and musculoskeletal ultrasonography was used to determine the distance of acromion-greater tuber-osity(AGT)of the affected side. Results After treatment,FMA-UE score,MBI score,AEMG,RMS and the distance of AGT improved in all the groups(|t|>10.850,P<0.001),and all the indexes were optimal in the position-limited group(F>42.031,P<0.001). Conclusion Robotic training for upper limb under postural limitation can further improve upper limb function and sub-luxation status,activities of daily living,and peri-shoulder muscle in patients with shoulder subluxation after stroke.

The existing mazes are mainly used to study the learning and memory of animals. However, there is still a lack of corresponding maze and method in the aspect of the observation and test of aquatic animal robots. For this purpose, the authors have developed a three-dimensional water maze combined with bilayer multi-channel which equips with stratified lines and tick marks. This device is a rectangular structure composed of one square bottom and four rectangular side walls, and the channels of every side wall are composed of one upper channel and two lower channels. The center of the upper channels is in the vertical center line of every side wall, and the two uper channels of adjacent side walls are at 90° degrees with each other, and the two lower channels of adjacent side walls are at 45° degrees with each other. There are stratified lines and tick marks on the side wall to test the spatial location and movement trajectories of aquatic animals. The carp robot was put into the water maze for the underwater experimental detection. The success rates of left and right steering at 135, 90 and 45 degrees as well as forward motion of the carp robots ( = 10) were over 60%. This study showed that the device could be used to observe and test the motion of the carp robot.

To solve the problem of precise positioning of carp brain tissue coordinates, it is proposed in this paper for a method for transforming the coordinates of magnetic resonance imaging of carp brain tissue into the coordinates of electrode implantation using a brain stereotaxic apparatus. In this study, the 3.0T magnetic resonance imaging instrument was used to scan the carp brain. We independently established the three-dimensional positioning coordinate system of the brain, the three-dimensional coordinate assistance system of skull surface and the three-dimensional coordinate assistance system in brain tissue. After two coordinate transformations, the magnetic resonance image coordinates of the brain electrodes implantation sites were converted into the three-dimensional stereotactic coordinate system to guide the electrodes implantation. The experimental groups were divided into two groups, A and B. Group A was the group of magnetic resonance imaging apparatus combining with the brain stereotaxic apparatus, and group B was the group of brain atlas combining with the brain stereotaxic apparatus. Each group had 20 tails of carps ( = 20). This two methods were used to implant the electrodes into the cerebellar motor area. The underwater experiments of the carp robots were carried out to test the two methods. The results showed that the accuracy of the implanted electrodes were 90% in group A and 60% in group B. The success rate of group A was significantly higher than that of group B ( < 0.05). Therefore, the new method in this paper can accurately determine the coordinates of carp brain tissue.
