To evaluate efficacy of microwave ablation in a primary clinical study, sixty patients (44 men, 16 women; mean age 53 years) with 96, 1-8 cm (mean $3.20{\pm}0.17$ cm) liver cancers were treated with 2,450-MHz internally cooled-shaft antenna. Complete ablation (CA) and local tumor progression (LTP) rates as well as complications were determined. CA rates in small (< 3.0 cm), intermediate (3.1-5.0 cm) and large (5.1-8.0 cm) liver cancers were 96.4% (54/56), 92.3% (24/26) and 78.6% (11/14), respectively. During a mean follow-up period of $17.17{\pm}6.52$ months, LTP occurred in five (5.21%) treated cases. There was no significant difference in the CA and LTP rates between the HCC and liver metastasis patient subgroups (P<0.05). Microwave ablation provides a reliable, efficient, and safe technique to perform hepatic tumor ablation.

Radiation-induced Cochlea Hair Cell Death: Mechanisms and Protection
Tan, Pei-Xin,Du, Sha-Sha,Ren, Chen,Yao, Qi-Wei,Yuan, Ya-Wei Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10
Cochlea hair cell death is regarded to be responsible for the radiation-induced sensorineural hearing loss (SNHL), which is one of the principal complications of radiotherapy (RT) for head and neck cancers. In this mini-review, we focus on the current progresses trying to unravel mechanisms of radiation-induced hair cell death and find out possible protection. P53, reactive oxygen species (ROS) and c-Jun N-terminal kinase (JNK) pathways have been proposed as pivotal in the processes leading to radiation hair cell death. Potential protectants, such as amifostine, N-acetylcysteine (NAC) and epicatechin (EC), are claimed to be effective at reducing radiation-inducedhair cell death. The RT dosage, selection and application of concurrent chemotherapy should be pre-examined in order to minimize the damage to cochlea hair cells.

To investigate the anti-obesity and hypolipidemic effects of Alpinia officinarum ethanolic extract (AOE) for the first time, anti-obesity models in vivo were used. Ten male Sprague-Dawley rats were fed normal control diet (NC); other groups of rats were fed a high-fat diet (HFD) with or without different proportions of AOE (AOE-1, 3%; AOE-2, 5%) for 6 weeks to examine feed intake, body and adipose tissue weight, serum total cholesterol (Total-C), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and leptin levels, alanine aminotransferase (ALT) and aspartate aminotranferase activities, hepatic Total-C and TG levels, and the pathological changes in liver and epididymal adipose tissues. Interestingly, feed intakes among the experimental groups were not significantly different. Body weight gains were significantly lowered in the AOE-1 and AOE-2 groups compared with the HFD group (P<.05) and near to the level of the NC group. AOE also improved the lipid profile in serum and the pathological changes in liver and adipose tissue and decreased the relative weights of epididymal and perirenal white adipose tissues. They improved lipid profile by lowering serum Total-C, TG, and LDL-C concentrations, leptin content, and the atherogenic index compared with the HFD group. The HDL-C concentration and the ratio of HDL-C/Total-C significantly increased compared with those of the HFD group. The serum ALT activity of the AOE-2 group was notably lower than that of the HFD group. Our data suggest that AOE can be considered as an anti-obesity agent that is effective for suppressing body weight gain and decreasing lipid profile.
