Pyrotinib in the Treatment of Women With HER2-Positive Advanced Breast Cancer: A Multicenter, Prospective, Real-World Study.

Background: HER2-positive breast cancer was aggressive, resulting in a poorer prognosis. This multicenter study analyzed the real-world data of women treated with pyrotinib-based therapy, aiming to describe their characteristics, treatment regimens, and to investigate the clinical outcomes.

Methods: A total of 141 patients with HER2-positive breast cancer were enrolled from February 2019 to April 2020.

Characterization of breast lesions using diffusion kurtosis model-based imaging: An initial experience.

Objective: To investigate the characterization of breast lesions using diffusion kurtosis model-based imaging.

Methods: This prospective study included 120 consecutive patients underwent preoperative DCE-MRI examinations and multi-b-value diffusion-weighted imaging (DWI). Among them, 88 malignant lesions and 44 benign lesions were detected, 56 normal fibroglandular breast tissue were selected as normal control.

Programmed Cell Death Protein-1 Predicts the Recurrence of Breast Cancer in Patients Subjected to Radiotherapy After Breast-Preserving Surgery.

Radiotherapy is the most important component of the comprehensive treatment of breast cancer, and immunocompromised patients respond with lower response rate. However, the role of programmed cell death protein-1, a critical immune molecule, in recurrence of breast cancer subjected to radiotherapy is unknown. A retrospective analysis was designed to explore the relevance.

Extensive diversity of Rickettsiales bacteria in two species of ticks from China and the evolution of the Rickettsiales.

Background: Bacteria of the order Rickettsiales (Alphaproteobacteria) are obligate intracellular parasites that infect species from virtually every major eukaryotic lineage. Several rickettsial genera harbor species that are significant emerging and re-emerging pathogens of humans. As species of Rickettsiales are associated with an extremely diverse host range, a better understanding of the historical associations between these bacteria and their hosts will provide important information on their evolutionary trajectories and, particularly, their potential emergence as pathogens.

The inhibitory role of Mir-29 in growth of breast cancer cells.

Mir-29 microRNA families are involved in regulation of various types of cancers. Although Mir-29 was shown to play an inhibitory role in tumorigenesis, the role of Mir-29 in breast cancer still remains obscure. In this study, we showed that Mir-29a is the dominant isoform in its family in mammary cells and expression of Mir-29a was down-regulated in different types of breast cancers.

Association of a LSP1 gene rs3817198T>C polymorphism with breast cancer risk: evidence from 33,920 cases and 35,671 controls.

Published data on the association between lymphocyte-specific protein 1 (LSP1) rs3817198T>C polymorphism and breast cancer risk are inconclusive. Hence, we conducted a meta-analysis of the LSP1 gene and risk of breast cancer to obtain the most reliable estimate of the association. PubMed, Embase and Web of Science databases were searched.

[Meta-analysis of association of tumor necrosis factor alpha-308 gene promoter polymorphism with gastric cancer].

Objective: To assess the association between tumor necrosis factor-alpha (TNF-alpha) gene promoter region -308 gene polymorphisms and gastric cancer (GC) susceptibility.

Methods: Published work about TNF-alpha-308 and GC from PubMed, EMBASE, Cochrane library in English and from Wanfang, CBM in Chinese were searched for relevant articles published by the end of July, 2009. Thirty-nine relevant articles were selected and 26 of them met the criteria.
