Objective To investigate the therapeutic effects and mechanisms of emodin(EMO)on dextran sulfate(DSS)-induced ulcerative colitis(UC)in mice.Methods DSS induced UC mouse model,detection of body weight,colon length and histopathological changes.Enzyme-linked immunosorbent assay(ELISA)was used to measure tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-10(IL-10),and myeloperoxidase(MPO)levels.Western blot analysis examined the expression of Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor κB(NF-κB)signaling pathway-related proteins.Flow cytometry assessed the ratio of helper T cells 17(Th17)to regulatory T cells(Treg).Additionally,16S rDNA sequencing was employed to evaluate gut microbiota composition.Results Compared with the normal group,DSS-treated mice exhibited significant weight loss,shortened colon length,and marked histological damage(P<0.001).EMO intervention,particularly at high doses,demonstrated dose-dependent improvements in body weight and colon injury(P<0.05).ELISA analysis showed EMO reduced TNF-α,IL-1β,and IL-6 levels while increasing IL-10(P<0.05).Western blot results indicated EMO inhibited abnormal activation of the TLR4/MyD88/NF-κB pathway and restored IκB.Conclusion EMO effectively mitigates DSS-induced ulcerative colitis(UC)inflammation and intestinal damage by regulating the TLR4/MyD88/NF-κB pathway,restoring Th17/Treg balance,and maintaining microbial homeostasis,providing theoretical support for its potential as a UC therapeutic agent.

Objective To investigate the personal dose level of occupational external exposure among interventional radiology workers in Liaoning Province of China, and to provide a reference for better occupational radiation protection. Methods According to the national standard GBZ 128—2016 Specifications for individual monitoring of occupational external exposure, the thermoluminescence method was used to measure the monitoring dose inside the lead clothes (H_W) and outside the lead clothes (H_N) of interventional radiology workers, and the Mann-Whitney U test and the Kruskal-Wallis H test were used for statistical analysis. Results Dual dosimeter monitoring data were collected from 307 interventional radiology workers in Liaoning Province in 2019, with a mean annual effective dose of 0.81 mSv and a maximum annual effective dose of 7.03 mSv, and 72.96% of the workers monitored had an annual effective dose of less than 1 mSv. The interventional radiology workers in tertiary hospitals had a significantly higher mean annual effective dose than those in secondary hospitals (0.95 mSv vs 0.65 mSv, P < 0.05). There was a significant difference in mean annual effective dose between departments (P < 0.05), and the department of interventional radiology had a significantly higher mean annual effective dose than the other departments (0.92 mSv vs 0.64 mSv), while the department of cardiology had a similar mean annual effective dose to the cerebrovascular department (0.78 mSv vs 0.78 mSv). Conclusion The occupational exposure dose of 307 interventional radiology workers in Liaoning Province meets the requirements in national regulations and standards and is higher than the national level, which suggests that radiation protection supervision and personal training should be further strengthened for interventional radiology.

Objective:Network meta-analyses (NMA) were used to evaluate and compare the effectiveness and acceptability of 20 maintenance treatment strategies for bipolar disorder (BD), such as lithium, imipramine, lithium+imipramine, carbamazepine, lithium+carbamazepine, valproic acid salt, lamotrigine, fluoxetine, olanzapine, aripiprazole, oxcarbazepine, quetiapine, lithium+valproic acid, risperidone long-acting injection, lamotrigine+valproic acid salt, aripiprazole+lamotrigine, paliperidone, ziprasidone, lurasidone, quetiapine sustained release.Methods:The Literatures were systematically searched from PubMed, EMBASE, PsycINFO, China national knowledge infrastructure (CNKI), Wanfang data (Wanfang), China biology medicine disc (CBMdisc) until 11/21/2019. Randomized controlled studies of the maintenance therapy with single or combination drugs for at least 12 weeks were selected. The primary outcome was the proportion of patients who got recurrence in the total number of patients. Efficacy of pharmacological treatments was assessed during the maintenance treatment treatments by using a random-effects network meta-analysis model within a Frequentists framework. Data analysis was performed in Stata 14.0 software.Results:40 studies covering with 10 431 patients were included, and 20 kinds of maintenance treatments for BD were performed. In terms of clinical efficacy, the top 5 treatments were lurasidone,quetiapine, olazanpine, lithium+carbamazepine, aripiprazole+lamotrigine.lithium ( RR:0.78, 95% CI: 0.62-0.97), olanzapine ( RR:0.51, 95% CI: 0.35-0.75), quetiapine ( RR:0.50, 95% CI: 0.33-0.74) and lurasidone ( RR:0.40, 95% CI: 0.19-0.83) were significantly superior to placebo. Conclusions:Lithium, olanzapine, quetiapine and lurasidone may be more effective than placebo,.but the efficaly of other monotherapy and combination therapy strategies need to be proven.
