Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Majority of type 2 diabetes mellitus (T2DM) patients are highly susceptible to several forms of cognitive impairments, particularly dementia. However, the underlying neural mechanism of these cognitive impairments remains unclear. We aimed to investigate the correlation between whole brain resting state functional connections (RSFCs) and the cognitive status in 95 patients with T2DM. We constructed an elastic net model to estimate the Montreal Cognitive Assessment (MoCA) scores, which served as an index of the cognitive status of the patients, and to select the RSFCs for further prediction. Subsequently, we utilized a machine learning technique to evaluate the discriminative ability of the connectivity pattern associated with the selected RSFCs. The estimated and chronological MoCA scores were significantly correlated with R= 0.81 and the mean absolute error (MAE) =1.20. Additionally, cognitive impairments of patients with T2DM can be identified using the RSFC pattern with classification accuracy of 90.54% and the area under the receiver operating characteristic (ROC) curve (AUC) of 0.9737. This connectivity pattern not only included the connections between regions within the default mode network (DMN), but also the functional connectivity between the task-positive networks and the DMN, as well as those within the task-positive networks. The results suggest that an RSFC pattern could be regarded as a potential biomarker to identify the cognitive status of patients with T2DM.

In addition to observing a 20-min multimedia video of non-invasive positive pressure ventilation nursing, the control group received traditional teaching and 30-min exercises, while the observation group received 30-min VR-based interactive teaching and 30-min targeted exercises. Standardized patients were applied for student assessment, and the scores of the two groups on days 1, 8, 15, and 29 were compared. At the same time, the students' self-efficacy and self-satisfaction were evaluated, and the number of skill training repetitions and time investment of the teachers from day 15 to 28 were recorded. SPSS 20.0 was used to perform the chi-square test and t-test. Results:The standardized patient assessment scores on days 1, 8, 15, and 29 were (69.14±7.02), (75.22±7.42), (79.14±7.99), and (90.14±8.94) in the observation group, respectively, and were (65.25±6.77), (70.14±6.95), (74.36±7.14), and (82.69±8.85) in the control group, respectively, which were all significantly different between the two groups ( P<0.05). The observation group also showed a significantly higher total General Self-Efficacy score [(24.60±3.68) vs. (20.47±3.25), P<0.05] and a significantly higher self-satisfaction score [(6.12±0.70) vs. (5.57±0.65), P<0.05] than the control group. For the teachers, the observation group had a significantly fewer number of training repetitions [(8.14±0.98) vs. (10.25±1.16), P<0.05] and significantly less time invested [(10.28±1.17) vs. (12.14±1.35) h, P<0.05] compared with the control group. Conclusions:VR technology can improve the teaching performance, self-efficacy level, and self-satisfaction level for clinical nursing internships, and reduce skill training repetitions and time investment for teachers.
