Background During pregnancy, negative emotions such as anxiety and depression may induce cortisol disruption. Cortisol can be transmitted to the fetus through the placental barrier, thereby affecting the neurodevelopment of the offspring. Objective To investigate the relationship between placental cortisol, maternal depression during pregnancy, and neurodevelopment of 3-month-old infants. Methods From September 2022 to September 2023, 171 pregnant women ordered routine prenatal checks at the obstetrics outpatient department of a tertiary hospital in Ningxia were selected using a prospective cohort design. After providing informed consent, these women participated in a questionnaire survey that covered general individual characteristics, prenatal depression, and sleep quality. At birth, placental samples were collected to measure cortisol levels using ELISA kits. Follow-up assessments on the neurodevelopmental of 3-month-old infants were conducted using the Warning Sign for Children Mental and Behavioral Development. LASSO regression analysis was conducted to screen the influencing factors of depression during pregnancy. Huber regression analysis was then applied to assess potential linear relationship between depression during pregnancy and placental cortisol levels. Log-binomial regression was used to analyze the linear relationships between cortisol levels and neurodevelopmental delay in 3-month-old infants. Additionally, a mediation effect model was fitted using R 4.3.3 to assess possible mediating role of cortisol in the association between prenatal depression and neurodevelopmental delay in 3-month-old infants. Results The positive rate of prenatal depression was 33.33%. Nine factors affecting prenatal depression were identified by LASSO regression, including rural residence, high school education or above, extroverted personality characteristics, moderate early pregnancy reactions, baby sex expectation, prenatal anxiety, family dysfunction, exposure to stressful life events during pregnancy, and moderate prenatal sleep quality. The Huber regression model showed a positive linear correlation between prenatal depression and placental cortisol (P<0.05). With or without controlling confounding factors, the results of log-binomial regression modeling showed that cortisol levels were associated with a reduced risk of neurodevelopmental delay in 3-month-old infants (crude model: RR=0.988, 95%CI: 0.9768, 0.9996, P＜0.05; adjusted model: RR=0.988, 95%CI: 0.9764, 0.9993, P＜0.05). A mediating effect of placental cortisol between prenatal depression and the risk of neurodevelopmental delay in 3-month-old offspring was found statistically significant (P=0.045), accounting for 67.0% of the total effect. Conclusion Prenatal depression is associated with elevated placental cortisol levels, and higher cortisol levels are found to be related to a lower risk of neurodevelopmental delay in infants. Placental cortisol mediates the relationship between prenatal depression and infant neurodevelopment.

Background Job burnout and depressive symptoms are prevalent among occupational populations, with a close relationship between them. Sleep quality, as a potential mediating factor, significantly affects the mental health of workers. Objective To explore the relationship between job burnout, sleep quality, and depressive symptoms, and determine whether sleep quality mediates the relationship between job burnout and depressive symptoms. Methods From April 25 to May 1, 2024, this study employed cluster sampling to conduct a questionnaire survey among individuals engaged in various occupations across five cities in the Ningxia Hui Autonomous Region. The questionnaires included socio-demographic information, as well as the Chinese Maslach Burnout Inventory (CMBI), the Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-9 (PHQ-9) for assessing burnout, sleep quality, and depressive symptoms, respectively. Out of the 4106 questionnaires distributed, a total of 3837 questionnaires were valid, and the valid recovery rate was 93.45%. The distribution among demographic variables in burnout, sleep quality and depressive symptoms were statistically analyzed. A binary logistic regression model was used for multifactor correlation analysis; Pearson correlation was used to test the correlation between burnout, sleep quality, and depressed mood. Modelling and mediated effect path mapping were performed using Amos 24.0 software. Results The postive rate of occupational burnout in the workers was 97.49% (3741/3837), the positive rate of poor sleep quality was 66.77% (2526/3837), and the positive rate of depressive symptoms was 75.68% (2904/3837). There were statistically significant differences in depressive symptoms by ages, shift types, working years, marital status, smoking habits, drinking habits, and exercising frequency (P < 0.05). The logistic model indicated that working years, drinking habits, job burnout, and overall sleep quality were significant factors influencing the occurrence of depressive symptoms (P < 0.05). The correlation analysis revealed positive correlations between depressive symptom scores and job burnout scores (r=0.045, P < 0.01), between depressive symptom scores and sleep quality scores (r=0.480, P < 0.01), and between job burnout scores and sleep quality scores (r=0.054, P < 0.01). Furthermore, the indirect effect of job burnout on depressive symptoms through sleep quality was 0.100 (95%CI: 0.204, 0.252; P < 0.01). Conclusion Job burnout and sleep quality are significant factors associated with the occurrence of depressive symptoms among occupational populations, and sleep quality plays a partial mediating role in depressive symptoms associated with job burnout. This finding may provide a scientific basis for developing intervention strategies to control depressive symptoms among workers.

Background Prenatal chronic psychological stress may increase the risk of allergic diseases in children, and eczema is the most common allergic disease in children, the pathogenesis of which is not yet fully understood. Objective To preliminarily clarify the changes in offspring intestinal flora after chronic stress exposure during pregnancy in rats that increases offspring immune imbalance and eczema susceptibility. Methods Thirty SPF-grade adult female SD rats were selected and randomly divided into a model group and a control group (n=15). Sixteen male rats were randomly divided into a model mating group and a control mating group (n=8). A 28-day chronic unpredictable mild stress (CUMS) model during pregnancy was established. On the 7th day of stress, male and female rats were caged in a ratio of 3:1. Blood samples were collected from female rats in each group via angular vein on the 1st day before stress, and on the 7th, 14th, 21st, and 28th days after stress. The content of plasma corticosterone during pregnancy was determined by enzyme-linked immunosorbent assay (ELISA). For the offspring rats, an eczema model was constructed using 2,4-dinitrochlorobenzene (DNCB). The number of scratching times of the offspring rats within 5 min was recorded. The offspring rats were divided into 4 groups: DNCB-CUMS group (MM), DNCB-control group (MC), solvent control-CUMS group (CM), and blank control group (CC), with 8 rats in each group. The eczema was induced once every 3 days, and the induction period was 12 d. The expression level of immunoglobulin E (IgE) in the serum of offspring rats after the eczema induction experiment were determined by ELISA. The concentrations of tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-2 (IL-2), interleukin-4 (IL-4), and interleukin-13 (IL-13) in the serum were quantified by multi-parameter flow cytometry. The composition and abundance of intestinal microbiota in the feces of offspring rats were detected by 16S rRNA high-throughput sequencing technology. Results The plasma corticosterone concentrations in the model group were higher than those in the control group on the 7th and 21st days of stress (P<0.05). On the 14th and 21st days of stress, the 1% sucrose preference percentages of female rats in the model group were lower than that in the control group. On the 7th, 14th, and 21st days of stress, the horizontal movement scores of female rats in the model group and the vertical movement scores on the 7th and 14th days were lower than those in the control group (P<0.05). After 6, 9, and 12 d of model building, the scratching frequencies in the MC group and MM group were significantly higher than those in the CC group and CM group (P<0.05). Moreover, there were differences in the contents of cytokines including IFN-γ, IL-2, TNF-α, IL-4, IL-13, and IgE among the offspring rat groups (P<0.05). The CM group and MM group led to an increase in the contents of TNF-α, IL-4, IL-13, and IgE cytokines (P<0.05), while the MM group caused a decrease in the contents of IFN-γ and IL-2 (P<0.05). After the eczema induction experiment, the α-diversity analysis showed that the Simpson index and Shannon index in the CM were higher than those in the CC (P<0.05), indicating that CUMS during the pregnancy of female rats could increase the species abundance of their offspring. The abundances of Prevotella and Lactobacillus in the CM group decreased (P<0.05). Conclusion Intestinal dysbiosis in offspring due to chronic prenatal psychological stress, which may be one of the mechanisms linking maternal stress to immune imbalance and increased susceptibility to eczema in offspring.

Background Pregnancy-related anxiety has a negative impact on the physical and mental health of pregnant women and the normal growth and development of the fetus. Establishing prediction models for pregnancy-related anxiety to screen associated predictive factors may provide important opportunities for prenatal intervention. Objective To establish a prediction model of pregnancy-related anxiety risk of pregnant women. Methods From January to July 2021, a questionnaire survey on pregnancy-related anxiety and predictors was conducted among pregnant women having routine prenatal check-ups provided by an obstetrics clinic of a tertiary grade A hospital in Ningxia. The socio-demographic characteristics of the subjects were collected, and the pregnant women were evaluated by the Life Event Scale (LES), Perceived Social Support Scale (PSSS), Family APGAR Index (APGAR), and Pregnancy-related Anxiety Questionnaire (PAQ). R 4.2.0 software was used to fit all selected variables by least absolute shrinkage and selection operator (LASSO) regression to identify predictors of pregnancy-related anxiety in the second and third trimesters. On the basis of logistic regression analysis, prediction models of pregnancy-related anxiety in the second and third trimesters were constructed, and the model nomogram and receiver operating characteristic curve (ROC) were drawn. The prediction effect of the model was evaluated by area under the curve (AUC). A calibration chart was drawn to evaluate the calibration of the model. Results A total of 1500 questionnaires were distributed, and 1448 valid questionnaires were recovered, with an effective rate of 96.53%. Among the 1448 pregnant women, the overall positive rate of pregnancy-related anxiety was 28.80% (417/1448), and the positive rates in the second and third trimesters were 29.21% (276/935) and 27.49% (141/513), respectively. The predictors entering the the second trimester model were age of marriage, family care, social support, family expectations for the fetus, physical condition during pregnancy, and whether experiencing life stressful events during pregnancy. The predictors entering the the third trimester model were pregnancy intention, physical discomfort, and whether experiencing life stress during pregnancy. A risk prediction model of pregnancy-related anxiety for the second trimester was established: risk of pregnancy-related anxiety=−0.07× marriage age +0.12× family care −0.03× social support −0.65× family expectation of fetal sex +0.42× physical condition during pregnancy +0.47× whether experiencing life stressful events during pregnancy. A risk prediction model of pregnancy-related anxiety for the third trimester was established: risk of pregnancy-related anxiety=−5.69+0.82× pregnancy intention +1.06× physical discomfort +0.94× whether experiencing life stressful events during pregnancy. The ROC curves of the two models were drawn. The AUC of the second trimester model was 0.71, and the AUC of related validation model was 0.68. The AUC of the third trimester model was 0.72, and the AUC of related validation model was 0.66. Conclusion The risk prediction models of pregnancy-related anxiety constructed based on LASSO regression and logistic regression have good prediction ability, and they suggest that pregnant women in the second trimester with short marriage age, high family care, low social support, family expectations for fetal sex, average physical condition, and experiencing life stress during pregnancy, and pregnant women in the third trimester with spontaneous pregnant intention, unintended pregnancy, physical discomfort, and experiencing life stress during pregnancy are high-risk groups for pregnancy-related anxiety.

Objective To investigate the clinical effects and influencing factors of remote ischemic post-conditioning RIPostC in the patients with post stroke fatigue(PSF).Methods Eighty patients with PSF were ran-domly divided into experimental group(n = 40)and control group(n = 40).Patients in both groups received routine drug therapy and rehabilitation training for stroke.The experimental group were additionally given RIPostC for four weeks.They were evaluated with National Institute of Health Stroke Scale(NIHSS),Barthel Index(BI),Mini-mental State Examination(MMSE),fatigue severity scale(FSS),Hamilton Anxiety Scale(HAMA),and Hamilton Depression Scale(HAMD).Results The score of NIHSS,FSS,HAMA and HAMD in the both groups were decreased,while the score of BI and MMSE were increased(P<0.01).The difference in the score of NIHSS,BI,MMSE,FSS,HAMA and HAMD between the two groups before and after treatment showed statistical significance(P<0.01)and the difference in the score was more significant in the experimental group.The risk factors of FSS were MMSE and HAMA.Conclusion RIPostC can effectively improve the neurological deficits,daily activity ability and cog-nitive function,alleviate fatigue,anxiety and depression in the patients of PSF.The influencing factors of PSF are cognitive function and anxiety.

ObjectiveTo observe the effect of Kinesio taping on salivation after stroke. MethodsFrom October, 2019 to January, 2021, 40 patients with salivation after stroke were randomly divided into control group (n = 20) and experimental group (n = 20). Both groups received routine medicine, routine rehabilitation for dysphagia and rehabilitation nursing, while the experimental group received Kinesio taping in addition, for three weeks. They were assessed with Functional Oral Intake Scale (FOIS), Water Swallow Test (WST) and Teacher Drooling Scale (TDS) before and after treatment. ResultsOne case dropped in the experimental group. The scores of FOIS, TDS and WST improved in both groups after treatment (|Z| > 2.000, P < 0.05), and improved more in the experimental group than in the control group (|Z| > 3.045, P < 0.01). ConclusionKinesio taping may relieve the salivation of patients with dysphagia after stroke.

Objective:To investigate the effects of chronic stress during pregnancy on depressive behavior and DNA methylation of insulin-like growth factor-2 ( IGF-2 )/long non-coding RNA ( lncRNA ) H19 in hippocampus of female offspring rats.Methods:A total of 32 SPF female SD rats were divided into model group and control group according to the random number table. The rats in the model group were treated with chronic unpredictable mild stress (CUMS) to establish the depression model, and the rats in the control group were fed normally.On the 7th day of stress stimulation, all female rats mated with male rats. One day before stress stimulation and 1, 7, 14, 21, 28 days after stress stimulation, blood samples were collected from the inner canthus vein of the rats to determine the plasma corticosterone concentration. Eight female pups were randomly selected from each group on postnatal day 28(PND28) and postnatal day 42 (PND42). Plasma corticosterone concentration was measured after angular vein blood collection. At PND42, the depression-like behavior of female pups in the two groups was measured by sucrose preference test, tail suspension test and forced swimming test. The expression of IGF-2/H19 and related transferases in hippocampus of offspring rats was detected by RT-PCR and Western blot. Methyl target technology was used to capture and sequence 19 CpG sites of IGF-2 differentially methylated region(DMR) fragment 2, 8 CpG sites in H19 imprinting control region (ICR) fragment 1 and 15 CpG sites in H19-ICR fragment 2, and calculate the methylation level of each CpG site. SPSS 26.0 was used for statistical analysis of relevant data by repeated measurement ANOVA, t test and non-parametric test. Results:(1) The data of plasma corticosterone content of the two groups of female rats at different times were analyzed by repeated measurement variance.The results showed that the the interaction effect between time and group was not significant ( F=2.997, P=0.066), and the main effect of time was significant ( F=4.44, P=0.010). The main effect of group was significant ( F=41.40, P=0.001). According to the independent effect analysis of factors between groups, on the 14th, 21st, and 28th days of stress, the plasma corticosterone concentration of the model group was higher than that of the control group (all P<0.001). (2) In the sucrose preference test, the total liquid consumption (11.10(10.38, 11.58) mL, 13.55(12.00, 15.77) mL, Z=-3.055, P=0.002), 1% sucrose water consumption ((5.50±1.30) mL, (8.56±2.04) mL, t=-3.582, P=0.003) and 1% sucrose preference percentage ( (51.35±8.69) %, (62.11±8.05) %, t=-2.576, P=0.022) of female pups in the model group were significantly lower than those in the control group. (3) The duration of immobility in tail suspension test ((126.95±39.89) s, (54.30±25.00) s, t=4.375, P=0.001) and forced swimming test ((7.97±6.66) s, (1.85±2.12) s, t=2.478, P=0.037) of female offspring in the model group were longer than those in the control group. (4) The expression of IGF-2 mRNA ((0.46±0.24), (1.00±0.00), t=3.821, P=0.019) and H19 mRNA ((0.60±0.25), (1.00±0.00), t=3.574, P=0.007) in hippocampus of female pups in the model group were lower than those of control group. The relative expression of IGF-2 protein in female offspring of model group was lower than that in control group ((0.77±0.04), (1.00±0.00), t=9.876, P=0.01). The relative expression of CCTC-binding factor (CTCF) mRNA ((1.29±0.12), (1.00±0.00), t=-4.850, P=0.003) and protein ((1.90±0.28), (1.00±0.00), t=-5.513, P=0.005) were higher than those in the control group. (5) The methylation levels of three CpG sites in the IGF-2 DMR region of female offspring in the model group were lower than those in the control group ( t=-3.21, -3.00, -3.34, all P<0.05), located at chr1215831028, chr1215831055 and chr1215831205, respectively. The methylation level of IGF-2 DMR fragment was lower than that of the control group ( t=-3.453, P=0.048). The relative expression levels of DNMT3A mRNA ( t=5.102, P=0.002), DNMT3A ( t=10.213, P<0.001) and DNMT3B ( t=4.169, P=0.014) in female offspring of the model group were lower than those in the control group. Conclusion:Chronic stress during pregnancy causes depression and despair in female offspring mice, and the mechanism may be related to the decrease of methylation level of imprinted gene IGF-2 DMR caused by the decrease of methyltransferase expression.

Objective To perform APACHEⅡand SOFA in assessmentof EICU patients with sepsis ,and analyze the risk factors. Methods A retrospective analysis from January 2014 to October 2015 in EICU of our hos-pital ,a total of 83 patients suffered from sepsis ,including sepsis group(30 cases)and septic shock(53 cases). PCT,PT,APTT,lactic acid,mechanical ventilation time and APACHE Ⅱ and SOFA score were collected, through the receiver-operating characteristic curve(ROC)index to predict the prognosis of patients with sepsis.Re-sults The mortality of the patients in the septic shock group,PT,APTT,APACHEⅡ,SOFA score,mechanical ventilation time and PCT were significantly higher than thosein the sepsis group(P<0.001). APTT,APACHEⅡ, SOFA score and mechanical ventilation time had significant difference (P ≤ 0.001) between survival and dead. The lactic acid level of the dead group was significantly higher than that in the survival group(P=0.038). The ar-ea under curve(AUC=0.806)of APACHEⅡscore was better than the SOFA score(AUC=0.765).The outcome of sepsis had correlation with APACHEⅡ,SOFA score,lactic acid,and mechanical ventilation time(P<0.05). Conclusion APACHE II and SOFA scores can accurately predict mortalityoutcome in emergency intensive care units patients with sepsis,especially the APACHEⅡscore.We can measure blood coagulation function,APACHEⅡ,SOFA score,PCT,lactic acid and mechanical ventilation time to assess the severity of patients with sepsis.

Objective To explore the effect of early virtual reality training in the rehabilitation of stroke patients with hemiplegia.Methods From June 2015 to May 2016, 60 cases of stroke patients from the Department of Rehabilitation of the First Affiliated Hospital of Wenzhou Medical University were randomly divided into observation group and control group, 30 cases in each group. The patients of control group received routine rehabilitation training program, and patients of the observation group received routine rehabilitation and virtual reality training. The two groups were trained for 6 weeks. The walking function, activities of daily living and mental status of the patient before and after training were evaluated by functional ambulation category scale (FAC), modified Barthel index (MBI), hospital anxiety and depression scale (HAD).Results Before training, FAC, MBI and HAD scores had no significant difference between patients of two groups (P>0.05). After 6 weeks of training, the scores of FAC, MBI and HAD in the two groups were better than those before training (P<0.05); After training, except for HAD (D), the indexes in the observation group were better than those in the control group (P<0.05).Conclusions Early virtual reality training can effectively improve the walking function and activities of daily living in stroke patients with hemiplegia, and relieve the patients' unhealthy psychological emotion.
