The aim of this study was to investigate the expression of macrophage migration inhibitory factor （MMIF）, hypoxia-inducible factor- 1 α（HIF- 1α ）and vascular endothelial growth factor （VEGF） in the serum and endometrial tissues of patients with endometriosis （EM） and the clinical significance. Eighty EM patients [American Reproductive Association stage Ⅰ （n=20）, stage Ⅱ （n=22）, stage Ⅲ （n=21） and stage Ⅳ （n=17）] were enrolled and divided into mild （10- 14 points, n=28）, moderate （16-24 points, n=27） and severe （26-30 points, n=25） dysmenorrhea groups. The control group included 40 healthy women of childbearing age who underwent routine healthcare examinations in the enrolment period. The expression of MMIF, HIF- 1α and VEGF in the serum and endometrial tissues was measured by enzyme-linked immunosorbent assay and Western blotting, respectively. Meanwhile, the sensitivity and specificity of serum MMIF, HIF-1α, and VEGF when separately used as single indexes or jointly used as one index were examined as well. The results showed that serum concentrations of MMIF, HIF-1α, and VEGF were significantly higher in EM patients than in controls （P〈0.05）. The expression of all three proteins in both serum and endometrial tissues increased significantly with the R-AFS stage （P〈0.05） and with dysmenorrheal severity （P〈0.05）. The sensitivity and specificity of the combined detection of serum MMIF, HIF-1α, and VEGF levels were significantly higher than those of single index detection （P〈0.05）. In conclusion, the expression of MMIF, HIF-1α, and VEGF in the serum and endometrial tissues may be used to assess the stage of EM and the severity of dysmenorrhea. Combined evaluation of MMIF, HIF-1α, and VEGF significantly improves the diagnostic sensitivity and specificity.

AZD1775 synergizes with SLC7A11 inhibition to promote ferroptosis

Tumor suppressor p53-mediated cell cycle arrest and DNA damage repair may exert cytoprotective effects against cancer therapies, including WEE1 inhibition. Considering that p53 activation can also lead to multiple types of cell death, the role of this tumor suppressor in WEE1 inhibitor-based therapies remains disputed. In this study, we reported that nucleolar stress-mediated p53 activation enhanced the WEE1 inhibitor AZD1775-induced ferroptosis to suppress lung cancer growth. Our findings showed that AZD1775 promoted ferroptosis by blocking cystine uptake, an action similar to that of Erastin. Meanwhile, inhibition of WEE1 by the WEE1 inhibitors or si RNAs induced compensatory upregulation of SLC7A11, which conferred resistance to ferroptosis. Mechanistically, AZD1775 prevented the enrichment of H3K9me3, a histone marker of transcriptional repression, on the SLC7A11 promoter by repressing the expression of the histone methyltransferase SETDB1, thereby enhancing NRF2-mediated SLC7A11 transcription. This finding was also validated using the H3K9me3 inhibitor BRD4770. Remarkably, we found that the nucleolar stress-inducing agent Actinomycin D(Act. D) inhibited SLC7A11 expression by activating p53, thus augmenting AZD1775-induced ferroptosis. Moreover, the combination of AZD1775 and Act. D synergistically suppressed wild-type p53-harboring lung cancer cell growth both in vitro and in vivo. Altogether, our study demonstrates that AZD1775 promotes ferroptosis by targeting cystine uptake but also mediates the adaptive activation of SLC7A11 through the WEE1-SETDB1 cascade and NRF2-induced transcription, and inhibition of SLC7A11 by Act. D boosts the anti-tumor efficacy of AZD1775 by enhancing ferroptosis in cancers with wild-type p53.

[ Objective] The aim of this study was to determine and analyze the pathogen and the reasons of duck viral hepatitis which is prevalent recently and difficult to control. [Method] Viruses were isolated from livers and spleens of ducks with typical clinical symptoms in Linyi, Weifang, Binzhou and other regions of Shandong Province. The pathogenic characteristics were observed by inoculation in chicken or duck embryo, RT- PCR, serological test, and duck regression. [ Result] Four duck hepatitis virus （DHV） strains were isolated, and the 5th passage allantoic fluid contained 10^3.41 -10^5.20 ELD50/mI. The serum cross protection rate was 20% -80% between the DHV stains and DHV type I. The mortalities of 4- day-old healthy ducks challenged by these four stains were 50% -100%. All challenged ducks had typical lesions of duck viral hepatitis, and the death peak appeared after 24-48 h. [Conclusion] The virulence of different DHV isolates has regional difference.

【目的】了解骨髓间充质干细胞在以异基因脾细胞输注致敏小鼠体内的归巢情况。【方法】正常同种异基因小鼠骨髓间充质干细胞的体外培养及鉴定后,体外予羧基荧光素二醋酸盐琥珀酰亚胺酯荧光染料标志,经尾静脉注射到致敏组和非致敏组小鼠体内(每组10只),在6 h、24 h和48 h处死动物,分别应用冰冻切片和流式检测方法了解骨髓间充质干细胞在各个脏器的分布情况。【结果】冰冻切片和流式检测结果均表明骨髓间充质干细胞在致敏小鼠体内迅速和持久在脾、肝脏聚集,而非致敏动物却没有明显聚集到肝脾等脏器,而是最终归巢到了骨髓。其中流式细胞仪定量结果表明:6 h时致敏小鼠脾脏荧光阳性细胞为(3.78±0.66)%,与同期正常小鼠脾脏结果比较P<0.05,有统计学意义;而在48 h时致敏小鼠骨髓荧光阳性细胞为(0.43±0.35)%,同期正常小鼠骨髓为(5.40±1.58)%,两者比较P<0.05,有统计学意义。【结论】应用异基因脾细胞致敏的小鼠体内肝脾等免疫脏器明显受到致敏影响,其对骨髓间充质干细胞体内归巢的定位具有很高的趋化吸附作用,中止了骨髓间充质干细胞正常状态下向骨髓的归巢。
