Objective To investigate the effects of light-at-night exposure on anxiety and depression behaviors in mice and to explore the underlying neural mechanisms.Methods Six-week-old male C57BL/6J mice were randomly assigned to a control(Ctrl)group and a light-at-night exposure(LAN)group.Mice in the LAN group were exposed to 460 nm blue light for 1 h daily during the zeitgeber time(ZT)13-14 while the Ctrl group mice were maintained under a 12-h light/12-h dark cycle.Behavioral tests were conducted at different time points following LAN exposure to evaluate anxiety and depression behaviors in the mice.Immunofluorescence staining was used to observe the effect of LAN on c-fos expressions in the medial prefrontal cortex(mPFC),basal ateral amygdala(BLA),paraventricular nucleus(PVN)and paraventricular thalamus(PVT).ELISA was performed to measure changes in serum corticosterone,adrenocorticotropic hormone(ACTH)and corticotropin-releasing hormone(CRH)levels.Golgi staining was applied to measurethe dendritic spine density and morphology from mPFC and CA1.Western blotting analysis was conducted to detect expression levels of brain-derived neurotrophic factors(BDNFs),phosphorylated tropomyosin receptor kinase B(p-TrkB)/TrkB,postsynaptic density protein 95(PSD95)and synaptophysin(SYP)in the mPFC.Results Mice exhibited anxiety-like behaviors after 14 days of LAN exposure,with depression-like behaviors emerging after 28 days.LAN exposure of 28 days led to a significant increase in the number of c-fos-positive neurons in the mPFC,BLA,PVN and PVT(P＜0.05),resulted in elevated serum corticosterone levels(P＜0.01)and reduced protein expression levels of BDNF and SYP(P＜0.05).Furthermore,there was a marked decrease in synapse numbers and synaptic density in the mPFC(P＜0.01).Conclusion Prolonged exposure to blue light at night enhances neuronal activity in the mPFC and BLA and suppresses the BDNF/TrkB signaling pathway by activating the hypothalamic-pituitary-adrenal axis(HPA),thus leading to synaptic structural and functional damage and inducing anxiety and depression behaviors in mice.

Objective:To explore the effect of knowledge-clinical-sharing (KCS) model in humanistic care training of pediatric nurses.Methods:A total of 182 specialist nurses who were trained in Hunan Children's Hospital from June 2019 to December 2019 were selected as the research objects. Among them, 102 specialist nurses from June 2019 to August 2019 were selected as the control group, and 80 specialist nurses from September 2019 to December 2019 were selected as the intervention group. The Jefferson empathy scale was used to compare the effect of humanistic training before and after the implementation. SPSS 22.0 statistical software was used, measurement data were test by F-test and t-test, and the counting data were analyzed by Chi-square test. Results:After the implementation of humanistic care training based on KCS model, the empathy ability score of the intervention group was higher than that of the control group [(80.23±5.33) vs. (78.14±4.37)], and the difference was statistically significant ( P < 0.01). There was no significant difference between neonatal and pediatric specialist nurses before and after the training. Conclusion:The phased humanistic training based on KCS model can improve the empathy ability of pediatric nurses and enhance their confidence in the clinical implementation of humanistic care. However, the humanistic training mode of pediatric nurses should be improved according to the hospital's own situation, so as to adapt to the development of nursing industry.

Objective:To compare and analyze the clinical curative effect and safety of chemoembolization with drug-loaded microspheres of different particle sizes (D-TACE) for the treatment of hepatocellular carcinoma.Methods:Clinical data of 281 cases with hepatocellular carcinoma treated with drug-loaded microspheres-transarterial chemoembolization (TACE) were retrospectively analyzed. According to the different particle sizes of drug-loaded microspheres, they were divided into 100~300 μm (small particle size) and 300~500 μm (large particle size) group. Tumor response rate and complication conditions at 1, 3, and 6 months after chemoembolization were compared. The overall survival time of the two groups were analyzed. Quantitative data conformed to normal distribution and homogeneity of variance were compared using t-test, while other with Wilcoxon signed rank-sum test. Qualitative data were compared using χ2 test. Kaplan-Meier method was used for survival analysis, and the differences in survival were analyzed using Log-rank test. P＜0.05 was considered as statistically significant. Survival curves and histograms were drawn using GraphPad Prism9.1 software. Results:The complete remission rates at 1, 3 and 6 months after surgery in the small and large particle size groups were 31.25%, 30.15%, and 42.45% and 18.25%, 15.79% and 24.74%, respectively, and the differences were statistically significant between groups (P 1 month=0.012, P 3 month=0.009, P 6 month=0.008, P＜0.05). The objective remission rates at 1, 3 and 6 months after surgery in the small and large particle size groups were 88.19%, 76.99%, and 70.75% and 81.02%, 72.81% and 53.60%, respectively. Six months after surgery, the small particle size group (objective response rate = 70.75%) was significantly higher than the large particle size group (objective response rate=53.6%, P=0.012). The disease control rates of the small particle size group were 95.14%, 83.33%, and 74.53%, while large particle size group were 91.24%, 81.58%, and 64.95%, respectively, with no statistically significant difference between the two groups. However, the incidence of postoperative biliary tumors (6.20%) was significantly higher in the small-size than large-size group (0.70%), and the difference was statistically significant ( P＜0.05, P=0.03). There were no statistically significant differences between other adverse events such as post-embolization syndrome, liver abscess, and myelosuppression. The median survival time of the small and large particle size groups was 31.8 months and 20.5 months, respectively, but the difference was not statistically significant ( P=0.182). Conclusions:In the treatment of hepatocellular carcinoma with D-TACE, the short-term curative effect of the small particle size group was better than large particle size group, but the incidence of biliary tumors was high, and D-TACE of different particle sizes had no significant effect on long-term survival.

Tuberculosis(TB) caused by the Mycobacterium tuberculosis(Mtb) is a worldwide public health threat.Microbiota in body affects human health and is involved in human diseases, and its clinical importance is begi-nning to be understood.In this review, studies on the relationship between the establishment of Mtb infection and microbiota as well as the development and antibiotic treatment of Mtb infection were discussed.Studies have shown that: (1) microbiota influences the establishment of Mtb infection; (2) co-infection of Helicobacter pylori alters susceptibility to Mtb infection and progression of active TB; (3) microbiota influences the progression of TB by regulating the nutritio-nal, metabolic and immune status of the host; (4) susceptibility to reinfection increases in TB patients treated with antibiotics, possibly due to T-cell epitope depletion of common intestinal non-Mtb Mycobacterium, the effects of antibio-tics are long-term in patients; (5) the occurrence of childhood TB is age-related and many factors such as co-infection and vaccine inoculation increase risk.An in-depth study of the relationship between the microbiota and TB will provide a new perspective on the prevention of TB.

Objective To compare the difference of the self-concept and self-esteem between the common and sub-orphan children,and explore the correlation of the self-concept and self-esteem.It can provide objective basis for appropriate psychological intervention.Methods Across-sectional survey,185 sub-orphan children of a sub-orphan charity school and 167 common children were investigated,Children's Self-concept Scale(PHCSS) and Children 's Self-esteem scale (CSES) were used to measure the self-concept and self-esteem.Results (1) There was no significant difference on total score of PHCSS between two children groups ((53.30± 13.34) vs (50.83± 11.53),t=1.86,P=0.06),but the score of intelligence and the situation in schools,appearance and properties,gregarious in sub-orphan children was significantly higher than that of common children,respectively((10.64±3.45) vs (9.23±3.47);(7.05±3.19) vs (6.31±2.73);(8.30±2.43) vs (7.72±1.86),P＜0.05).(2) There was no significant difference on total score of CSES between two children groups(P＞0.05),but the score of the sports and achievement of CSES in sub-orphan children was significantly less than that of common children,respectively (P＜ 0.05).(3) There was significant correlation between self-concept and self-esteem in sub-orphan children (P＜0.05).Conclusion There are some psychological problems in sub-orphan children and need to implement appropriate psychological intervention.
