Abstract Background To retrospectively evaluate the effectiveness and safety of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) with a multi‐pin bipolar system. Methods Between August 2005 and December 2006, 18 patients with 30 HCCs (3.40 ± 1.24 cm, range 1.30–6.0 cm; median number of treated lesions is two per patient, range, 1–3) underwent percutaneous RFA with a multi‐pin bipolar system under ultrasound guidance. The primary end‐point were treatment efficacy, major and minor complications, and the secondary end‐point were overall survival and tumor‐free survival. Results Complete ablation with conformed shape to the index tumor was achieved in 16 of 18 patients, and 28 of the 30 tumors were completely ablated. On follow‐up, local and distant intrahepatic tumor progression rates were 12.5% (2 of 16 patients) and 62.5% (10 of 16 patients). There was no patient who developed extrahepatic metastasis. There were no major complications. The 1‐, 2‐year overall survival rates for all patients were 83.3%, 55.6%, respectively, and the corresponding tumor‐free survivals were 50.0%, 22.2%, respectively. Conclusion RFA with a multi‐pin bipolar system was effective and safe for HCC. A large ablation volume could be achieved which conformed to the shape of the index tumor. J. Surg.

Organic Moiety‐Regulated Photocatalytic Performance of Phosphomolybdate Hybrids for Hexavalent Chromium Reduction

Chemistry - An Asian Journal (2021)

Abstract Visible‐light‐driven photocatalytic Cr(VI) reduction is a promising pathway to moderate environmental pollution, in which the development of photocatalysts is pivotal. Herein, three hourglass‐type phosphomolybdate‐based hybrids with the formula of: (H 2 bpe) 3 [Zn(H 2 PO 4 )][Zn(bpe)(H 2 O) 2 ]H{Zn[P 4 Mo 6 O 31 H 6 ] 2 } ⋅ 6H 2 O ( 1 ) Na 6 [H 2 bz] 2 [ZnNa 4 (H 2 O) 5 ]{Zn [P 4 Mo 6 O 31 H 3 ] 2 } ⋅ 2H 2 O ( 2 ) and (H 2 mbpy) {[Zn(mbpy)(H 2 O)] 2 [Zn(H 2 O)] 2 }{Zn[P 4 Mo 6 O 31 H 6 ] 2 } ⋅ 10H 2 O ( 3 ) (bpe=trans‐1,2‐bi(4‐pyridyl)‐ethylene; bz=4,4′‐diaminobiphenyl; mbpy=4,4’‐dimethyl‐2,2’bipyridine) were synthesized under the guidance of the functional organic moiety modification strategy. Structural analysis showed that hybrids 1 – 3 have similar 2D layer‐like spatial arrangements constructed by {Zn[P 4 Mo 6 ] 2 } clusters and organic components with different conjugated degree. With excellent redox properties and wide visible‐light absorption capacities, hybrids 1 – 3 display favourable photocatalytic activity for Cr(VI) reduction with 79%, 70% and 64% reduction rates, which are superior to that of only inorganic {Zn[P 4 Mo 6 ] 2 } itself (21%). The investigation of organic components on photocatalytic performance of hybrids 1 – 3 suggested that the organic counter cations (bpe, bz and mbpy) can effectively affect the visible‐light absorption, as well as the recombination of photogenerated carriers stemmed from {Zn[P 4 Mo 6 ] 2 } clusters, further promoting their photocatalytic performances towards Cr(VI) reduction. This work provides an experimental basis for the design of functionalized photocatalysts via the modification of organic species.
