Berberine targeting TRIM25 induced cervical cancer HeLa cell apoptosis / 中国药理学通报

Aim To study the mechanism and target of apoptosis induced by berberine ( BBR) in cervical cancer HeLa cells. Methods Drug affinity responsive target stability (DARTS) and mass spectrometry (MS) were used to identify the potential binding proteins of berberine. The binding affinity between berberine and candidate target protein was detected by microscale thermophoresis technique (MST) , and cellular thermal shift assay (CETSA) was used to detect the binding of berberine to candidate target proteins in living cells. CRISPR/Cas9 gene editing technique was used to establish candidate target protein TRIM25-deficient tumor cell lines. CCK-8 assay and Annexin V/propidium iodide combined with flow cytometry were used to detect the inhibitory and apoptotic effects of berberine on wild-type and TRIM25-KO cells. Western blot was used to detect the effect of berberine on TRIM25 and its substrate protein levels.Results DARTS found that after berberine treatment, the sensitivity of TRIM25 to pronase proteolysis showed the most significant change. MST and CETSA assays showed that berberine directly bound to TRIM25 at molecular and cellular levels, and its dissociation constant was 4.02 μmol • L

Abdominal splenosis: CT and MRI features of 2 cases / 中华创伤杂志(英文版)

Splenosis is ectopic autotransplantation of splenic tissue after splenic trauma or surgery.(1) The most frequent locations are the surface of visceral peritoneum and parietal peritoneum. Liver and retroperitoneum are rarely involved.(1,2) We present here 2 cases of splenosis involving the liver and retroperitoneum with clinical information, imaging findings, and literature review.

IHE technical framework and its application / 中国医疗器械杂志

Firstly, IHE technical framework is introduced in this paper, and the sub-framework of Schedule Workflow is also described. Secondly, the development of IHE in Japan and the formation of IHE-J are presented, and in combination with IDS system's practice in IHE-J, some ideas about developing IHE in China and the relative methods of implementation are discussed.
