Superficialization of dilated radial artery for vascular access: A case report.

Successful hemodialysis treatment need a well functioning vascular access (VA) allowing two cannulation sites with enough blood flow have minimum adverse events. The expectations, age of the HD population are rising as well as the lack of conventional methods due to central venous exhaustion, we have to choose some complex access, including complex or tertiary vascular access mentioned in 2018 Clinical Practice Guidelines of the European Society for Vascular Surgery (ESVS) and the option to abandon the venous circuit in instead of arterial system, including arterial-arterial graft and arterial superficialization. This article report a complicated case of AVF dysfunction, central venous stenosis due to central venous catheter and aortic dissection stent as well as lower extremity arteriosclerosis occlusion, using the simple method of superficialization of enlarged radial artery to maintain hemodialysis.

Qici Sanling decoction suppresses bladder cancer growth by inhibiting the Wnt/Β-catenin pathway.

Context: Bladder cancer, which has high recurrence, is one of the most deadly cancers in the world. Astragalus propinquus Schischkin (Fabaceae) and Sagittaria sagittifolia L. (Alismataceae) are important herbs reported to be effective in cancer therapy. Objective: The efficacy of QCSL (Qici Sanling decoction) in bladder cancer treatment was examined. Materials and methods: T24 cells were injected into the flanks of nude mice and the mice were randomly divided into five groups: control; 20 mg/kg XAV-939 (an inhibitor of the WNT/ß-catenin pathway); QCSL (100, 200, or 400 mg/kg). After 7 weeks, the mice were anaesthetised using isoflurane and the xenografts were excised to perform further experiments. Results: Both XAV-939 (tumour volume: 379.67 ± 159.92 mm3) and QCSL (796.18 ± 101.6 mm3) dramatically suppressed tumour growth comparing with control group (3612.12 ± 575.03 mm3). XAV-939 and QCSL treatments decreased cell proliferation from 56.3 ± 0.05% to 29.02 ± 0.07% and 37.51 ± 0.04%, respectively. In agreement, more infiltration of immune cells and pyknotic cells upon XAV-939 (apoptosis rates: 43.92 ± 0.03%) and QCSL (34.57 ± 0.04%) treatment comparing with control group (15.59 ± 0.03%) were observed. Furthermore, TUNEL staining of xenograft tumours illustrated more apoptotic cells upon XAV-939 and QCSL treatment. Mechanistically, XAV-939 and QCSL treatments significantly inhibited WNT/ß-catenin pathway in T24 xenograft tumours. Discussion and conclusions: Our findings give new insights into the role of QCSL in bladder cancer and explore potential mechanisms contributing to the therapeutic effects of QCSL in bladder cancer.
