Objective To observe the traditional Chinese medicine (TCM) and umbilical treatment on diarrhea-predominant irritable bowel syndrome(IBS-D)with mental disorders. Methods Thirty-seven cases with IBS-D were randomized into a treatment group(33 cases) and a control group(31 cases). The treatment group was given Shugan-Jianpi TCM decoction and pepper umbilical dressing. The control group was given Pinaverium Bromide Tablets and Flupentixol and Melitracen tablets. After having been treated for 4 weeks, Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), IBS Symptom Severity Scale(IBS-SSS), IBS quality of life questionnaire (IBS-QOL) were determined. Results After the treatment, HAMD, HAMA, IBS-SSS in the treatment group and the control group all significantly decreased (the treatment group t=14.280, 13.530, 18.847,the control group t=11.514, 9.424, 13.829, P<0.01), and IBS-QOL increased markedly(t=-16.848, -11.712, P<0.01). Compared with HAMA, IBS-SSS and IBS-QOL in treatment group, the control group showed statistical difference(t=-3.183, -2.549, 3.904, P<0.01 or 0.05). The total effective rate of the treatment group was 94%higher than 75%of the control group(χ2=4.727, P<0.05). Conclusion Shugan-Jianpi TCM decoction and pepper umbilical dressing can improve the clinical symptoms and psychological symptoms and improve the quality of life of IBS-D patients.

Objective:To investigate changes in mRNA and protein expression of interleukin-27(IL-27)in glomerular podocyte injury caused by Puromycinonucleoside(PAN), and to explore the mechanism of the protective effect of Tacrolimus(FK506)on glomerular podocyte injury.Methods:Glomerular foot cells from mice were cultured in vitro and divided into 3 groups, which were the control group, PAN group and FK506 group.The morphology of 3 groups of foot cells was observed under a microscope after 8 h, 24 h, and 48 h treatment.The changes in IL-27 concentrations were detected by analyzing the enzyme-linked immunosorbent assay(ELISA)method.The cultured foot cells were then collected.The changes of IL-27 mRNA expression were measured by real-time fluorescence quantitative PCR(qPCR), and the changes of IL-27 protein expression were detected by Western blot. Results:(1)At each time point(8 h, 24 h, 48 h), the cells of the PAN group had smaller volume and different morphology than the cells of the control group, and the cells of the FK506 group was larger and fuller than the cells of the PAN group.(2)The concentrations of IL-27 in the PAN group [(110.00±3.52) ng/L, (302.00±6.23) ng/L, (397.00±8.92) ng/L] were significantly higher than those in the control group [(90.00±5.12) ng/L, (85.00±4.21) ng/L, (88.00±4.20) ng/L] and those in the FK506 group [(96.00±4.17) ng/L, (107.00±4.86) ng/L, (112.00±6.24) ng/L] at 8 h, 24 h and 48 h(all P<0.05). (3)At each time point(8 h, 24 h, 48 h), the IL-27 mRNA expression of the PAN group(1.25±0.11, 1.57±0.08, 1.73±0.13)was significantly higher than that of the control group(1.02±0.02, 1.10±0.04, 0.96±0.02)(all P<0.05). Compared with the control group, the IL-27 mRNA expression of the FK506 group did not significantly increase at 8 h (1.10±0.06), and showed a slight increase at 24 h and 48 h(1.21±0.04, 1.30±0.09). Compared with PAN group, HC506 group were all lower (all P<0.05). (4)At each time point(8 h, 24 h, 48 h), the expression of IL-27 protein in the PAN group(0.94±0.04, 1.56±0.07, 1.63±0.04) was significantly higher than that in the control group(0.83±0.04, 0.85±0.03, 0.83±0.05), there was significant difference(all P<0.05). Compared with the PAN group, the expression of IL-27 protein in the FK506 group(0.84±0.05, 0.89±0.04, 0.91±0.06)was not significantly different at 8 h, but decreased significantly at 24 h and 48 h, there was significant difference ( P<0.05). Conclusions:IL-27 is involved in the pathogenesis of kidney diseases.FK506 can prevent the glomerular podocyte injury by reducing the expression of IL-27.This study provides experimental basis for clinical application of FK506 in the treatment of kidney diseases.

Objective To investigate the effect of parent-child alienation on depression in surface ship officers and soldiers based on the theory of"diathesis-stress",and the mediating role of resilience between parent-child alienation and depression in them.Methods A cross-sectional study was conducted on 599 officers and soldiers from a surface ship unit.The participants were surveyed with inventory of alienation toward parents,connor-davidson resilience scale and patient health questionnaire-9 to obtain and analyze their demographic-military characteristics of their depression scores.The participants with depression scores ≥5 were recruited as the subjects,and Spearman correlation analysis was used to explore the correlation among parent-child alienation,resilience and depression.On the basis of hierarchical regression analysis,AMOS software was used to establish a structural equation modelling of intermediary effects.Results The depression score was 1(0,4)in the participants,and the depression scores of those with service length ≥11 years were comparatively higher than those with shorter length.Our results indicated that parent-child alienation was positive correlated with depression(r=0.451,P＜0.001),while resilience was negatively correlated with depression and parent-child alienation(r=-0.412,-0.407,P＜0.001).Regression analysis revealed that parent-child alienation had a direct positive predictive value for depression(β=0.574,P＜0.001),and resilience showed a negative predictive value for depression(β=-0.211,P＜0.01).Model analysis displayed that resilience had a significant mediating role in the effect of parent-child alienation on depression among these surface ship officers and soldiers,with an effect value of 0.088,and accounting for 15.86％of the total effect.Conclusion Parent-child alienation has a significant influence on depression among surface ship officers and soldiers,with resilience playing a partial mediating role.

Objective To investigate the influence of stress on insomnia among plateau soldiers,and explore the mediating role of parent-child alienation and the moderating role of emotion regulation strategies in this relationship.Methods A cross-sectional study design was adopted in this study.Our Self-designed General Information Questionnaire,Plateau Soldiers Stressor Scale,Insomnia Severity Index,Inventory of Alienation towards Parents,and Emotion Regulation Scale were employed to survey 2 065 plateau soldiers at an average altitude of 4 200 m.With aid of SPSS 26.0 statistics,descriptive analysis,correlation analysis and regression analysis were applied to analyze stress status,parent-child alienation,insomnia and emotion regulation in the participants,and then a structural equation model was established.Results ① The scores of stress,parent-child alienation and insomnia were significantly higher in the participants who were older,well educated(P＜0.01)and were or had been in a marital relationship(married,divorced,or widowed)(P＜0.001)than those without above conditions.② Significant pairwise positive correlations were observed among stress,parent-child alienation,insomnia,cognitive reappraisal,and expressive suppression(r=0.08～0.61,P＜0.001).③ Stress and expressive suppression could positively predict parent-child alienation(β=0.14～0.43,P＜0.001),and stress,parent-child alienation and expressive suppression could positively predict insomnia(β=0.04～0.25,P＜0.01).Cognitive reappraisal could not significantly predict parent-child alienation or insomnia.④ Parent-child alienation towards parents partially mediated the relationship between stress and insomnia,with a mediation effect accounting for 7.29％of the total effect.⑤ Expressive suppression moderated the impact of stress on insomnia(β=-0.01,P＜0.001),and the higher expressive suppression level mitigated the adverse effect of stress on insomnia when compared with the lower expressive suppression level.Conclusion For plateau soldiers,stress significantly predicts insomnia,with parent-child alienation playing a mediating role.Furthermore,a higher level of expressive suppression can effectively buffer the influence of stress on insomnia.

Objective To explore the current status of post-traumatic stress disorder(PTSD)symptoms among military officers at high altitude,determine the effects of childhood trauma experiences on the symptoms,and investigate the role of parent-child alienation in the process.Methods A cross-section study was conducted on 238 male military officers at high altitude subjected with cluster sampling.All of them were surveyed with childhood trauma question(CTQ),inventor of alienation toward parents(IAP),and Post-traumatic Stress Disorder Checklist(PCL-C)in October 2021.Then the mediating effect of parent-child alienation on childhood trauma and PTSD symptoms was investigated.Results ①The prevalence of PTSD-positive symptoms was 8.5％among the military officers at high altitude.②The prevalence of PTSD-positive symptoms was 15.6％for the military officers with childhood trauma,which was significantly higher than that of those without childhood trauma(5.1％,Chi-square=7.27,P＜0.01).③ PTSD symptoms,childhood trauma experiences and parent-child alienation were significantly positively correlated with each other(r=0.35～0.76,P＜0.01).④ Both childhood physical abuse(β=1.05,P＜0.001)and parent-child alienation(β=0.39,P＜0.01)could positively predict the severity of PTSD symptoms for them.⑤Parent-child alienation played a partial mediating role in the association between physical abuse and PTSD symptoms(β=1.16,95％CI:0.54～1.75).Conclusion Military officers at high altitude with childhood trauma have a higher prevalence of PTSD-positive symptoms and more severe symptoms.Childhood physical abuse can not only directly affect PTSD symptoms,but also indirectly affect its severity through parent-child alienation.
