World Journal of Gastroenterology 2014年第43期20卷 16377-16380页

作者： Cheng-En Wang Cheng-Jian Sun Shuai Huang Yan-Hua Wang ling-ling xie Department of Interventional Radiology Affiliated Hospital of Qingdao University

Calcification of the portal venous system is a rare entity that can be incidentally discovered during computed tomography (CT). We describe a case of extensive calcifications in the portal venous system in a middle-aged male patient with hepatocellular carcinoma (HCC). This patient presented with epigastric pain that had no obvious origin prior to admission. Laboratory examinations were positive for hepatitis B surface antigen and α-fetoprotein, and severe esophageal and gastric varices were detected during gastroscopy. Abdominal X-ray plain film showed well-defined linear and track-like calcification, with irregular margins directed along the course of the portal venous system. CT revealed extensive calcifications along the course of the portal, splenic, superior mesenteric and gastroesophageal veins. He underwent splenectomy 22 years ago due to splenomegaly and partial hepatectomy seven months before because of HCC of low-grade differentiation, confirmed by pathology. Finally, the patient was diagnosed with postoperative recurrent HCC and extensive portal venous system calcification after selective hepatic angiography under digital subtraction angiography.

Background: Occult invasive cervical cancer discovered after simple hysterectomy is not common, radical parame?trectomy(RP) is a preferred option for young women. However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early?stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid ***: A total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early?stage cervical cancer were ***: Of the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41 years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10–30 mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9 mm; only one patient had more than 50% stromal invasion, and four patients had lymph?vascular space invasion(LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico?vaginal istula, and ileus(1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced ***: Perioperative complications following RP were common, whereas the incidence of parametrial involve?ment was very low among selected e

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.

Investigation of the Mechanism of Tangent Bifurcation in Current Mode Controlled Boost Converter

引用

Circuits and Systems 2011年第1期2卷 38-44页

作者： ling-ling xie Ren-xi Gong Kuang Wang Hao-ze Zhuo 不详

Tangent bifurcation is a special bifurcation in nonlinear dynamic systems. The investigation of the mechanism of the tangent bifurcation in current mode controlled boost converters operating in continuous conduction mode (CCM) is performed. The one-dimensional discrete iterative map of the boost converter is derived. Based on the tangent bifurcation theorem, the conditions of producing the tangent bifurcation in CCM boost converters are deduced mathematically. The mechanism of the tangent bifurcation in CCM boost is exposed from the viewpoint of nonlinear dynamic systems. The tangent bifurcation in the boost converter is verified by numerical simulations such as discrete iterative maps, bifurcation map and Lyapunov exponent. The simulation results are in agreement with the theoretical analysis, thus validating the correctness of the theory.
