Background:
Ferroptosis is a newly discovered form of iron-dependent oxidative cell death
characterized by lethal accumulation of lipid-based reactive oxygen species (ROS). It is distinct from
other forms of cell death including apoptosis, necrosis, and autophagy in terms of morphology, biochemistry
and genetics.
Discussion:
Ferroptosis can be induced by system xc- inhibitors or glutathione peroxidase 4 (GPx4)
inhibitors, as well as drugs such as sorafenib, sulfasalazine (SAS), and artesunate (ART). Ferroptosis
has been recently shown to be critical in regulating growth of tumors, such as hepatocellular carcinoma
(HCC), renal cell carcinoma (RCC), non-small cell lung cancer (NSCLC), ovarian cancer, pancreatic
carcinoma, and diffuse large B cell lymphoma (DLBCL). Ferroptosis is also associated with
resistance to chemotherapeutic drugs and the anti-tumor efficacy of immunotherapy.
Conclusion:
This review summarizes the mechanism of ferroptosis and its relationship with different
types of tumors, to advance our understanding of cell death and to find a novel approach for clinical
cancer management.
The results of this study suggest that bimaxillary surgery promotes less decrease on the upper airway than mandibular setback surgery alone for the correction of the skeletal class III malocclusion.
The aim of this study was to assess the quality of life (QOL) of Chinese home-based advanced-stage cancer patients and to evaluate the association between the disclosure of cancer diagnosis and QOL. An interview-based survey was conducted from December 2009 to June 2010 in the home-based hospice of the First Affiliated Hospital of Chongqing Medical University, China. The principal finding of this study demonstrated that patients who did not have knowledge of their diagnosis exhibited better physical and emotional QOL compared with those who had knowledge of their diagnosis.
The aim of this study was to investigate the prevalence and predictive factors for poor sleep quality among migraineurs in a tertiary hospital headache clinic in southwest China. In this study, we used a visual analog scale (VAS), the Pittsburgh Sleep Quality Index (PSQI), and the Hospital Anxiety and Depression Scale (HADS) to assess headache intensity, sleep quality as well as anxiety and depression symptoms. In 211 subjects who were assessed continuously, we found that the average PSQI score was 8.03 ± 4.71, and 130 (61.61 %) migraineurs exhibited poor sleep quality (PSQI >5). Poor sleep quality was largely expressed as experiencing an extended sleep latency period, daytime dysfunction, poor subjective sleep quality, and short sleep duration. The primary factors that predicted poor sleep quality included the migraine history and comorbidity with anxiety and/or depression. Moreover, we found that most migraineurs did not adopt treatment for their poor sleep quality. Only 17 (8.06 %) patients used sleeping medication to improve their poor sleep quality; however, this medication was not effective in 16 (94.12 %) patients. Therefore, it is highly important to resolve poor sleep quality in migraineurs.
This study aimed to investigate the prevalence and risk factors for anxiety and depression symptoms in outpatient migraineurs in mainland China. In addition, we evaluated whether the Hospital Anxiety and Depression Scale (HADS) provided sufficient validity to screen depression and anxiety. A cross-sectional study was conducted consecutively at our headache clinic. Migraine was diagnosed according to International Classification of Headache Disorders, 2nd edition (ICHD-II). Demographic characteristics and clinical features were collected by headache questionnaire. Anxiety and depression symptoms about migraineurs were assessed using HADS. Several questionnaires were simultaneously used to evaluate patients with depressive disorder including the Hamilton Depression Rating Scale-17 (HAMD), Hamilton Anxiety Rating Scale (HAMA) and HADS. Pearson correlation analysis was applied to test the validity of HADS. 176 outpatients with migraine (81.8 % female) were included. Overall, 17.6 and 38.1 % participants had depression and anxiety, respectively. Possible risk factors for depression in migraineurs included headache intensity of first onset of migraine, migraine with presymptom, migraine with family history and migraine disability. The possible risk factors for anxiety included fixed attack time of headache in one day and poor sleeping, and age represented a protective factor for anxiety. The correlation coefficient of HADS-A and HADS-D with HAMA and HAMD was 0.666 and 0.508, respectively (P < 0.01). This study demonstrates that depression and anxiety comorbidity in our mainland Chinese migraineurs are also common, and several risk factors were identified that may provide predictive value. These findings can help clinicians to identify and treat anxiety and depression in order to improve migraine management.
