The quadrant system, although helpful in determining screw placement in hips with a normal center of rotation, can be misleading and of less value in guiding screw insertion to augment acetabular shells for hips with a high dislocation. We believe that a safe zone specific to hips with a high dislocation should be used to guide transacetabular screw fixation.

Despite great advances in cancer therapy, drug resistance is a difficult hurdle to overcome that requires development of anticancer agents with novel and effective modes of action. In a number of studies, lytic peptides have shown remarkable ability to eliminate cancer cells through a different way from traditional treatments. Lytic peptides are positively charged, amphiphilic, and are efficient at binding and disrupting the negatively charged cell membrane of cancer cells. In this study, we described the anticancer properties of a lytic peptide that was developed on the basis of the alignment of amphiphilic BH3 peptides. Our results demonstrated that the positive charge and conformation constraint were favourable for efficient cancer cell elimination. Artificial BCL-2 homology 3 peptides (ABH3) exhibited effective anticancer effects against a series of cancer cell lines in vitro and in HeLa human cervical tumour xenografts in vivo. ABH3 induced cell death in an apoptosis-independent manner through the lytic properties of the peptide that caused disruption of cell membrane. Our results showed that charge tuning and conformation constraining in a lytic peptide could be applied to optimise the anticancer activity of lytic peptides. These results also suggest that ABH3 may be a promising beginning for the development of additional lytic peptides as anticancer reagents.

Antiphospholipid syndrome (APS) is characterized by arterial and venous thrombosis and/or morbid pregnancy, accompanied by persistent antiphospholipid antibody (aPL) positivity. However, due to the complex pathogenesis of APS and the large individual differences in the expression of aPL profiles of patients, the problem of APS diagnosis, prognosis judgment, and risk assessment may not be solved only from the antibody level. It is necessary to use new technologies and multiple dimensions to explore novel APS biomarkers. The application of next-generation sequencing (NGS) technology in diseases with a high incidence of somatic mutations, such as genetic diseases and tumors, has been very mature. Thus, we try to know the research and application progress of APS by NGS technology from genome, transcriptome, epigenome and other aspects. This review will describe the related research of NGS technology in APS and provide more reference for the deep understanding of APS-related screening markers and disease pathogenesis.
