RESUMEN
The known Chinese fauna of the genus Sathytes Westwood (Pselaphinae: Batrisini) is comprised of 15 species. Here we describe five more species from eastern China: S. communis Shen Yin, sp. nov. (from Anhui, Zhejiang and Jiangxi), S. fenghuang Shen Yin, sp. nov. (from Zhejiang), S. jinggang Shen Yin, sp. nov. (from Jiangxi), S. obliquus Shen Yin, sp. nov. (from Zhejiang), and S. similis Shen Yin, sp. nov. (from Zhejiang and Jiangxi). Moreover, Sathytes larinus Yin Li, originally known from Fujian, is newly recorded from Zhejiang.

The pselaphine genus Sathytes Westwood is represented in Borneo by a single species. In this paper we describe four new species: S. borneoensis sp. nov., S. liuyei sp. nov., S. larifuga sp. nov., and S. shihongliangi sp. nov. All new species were collected by light traps in Sabah, and show unique combinations of male sexual characters that lead to ready species discriminations. A key to Sathytes species from Borneo is appended.

Fructose-1,6-bisphosphatase 1 (FBP1) is a rate-limiting enzyme in gluconeogenesis. Recently, the catalytic activity-independent function of FBP1, hypoxia-induced factor (HIF) repression in the nucleus, was identified. The aim of the present study was to investigate the association between FBP1 and hypoxia-related gene expression in clear cell renal cell carcinoma (ccRCC). The protein expression levels of FBP1, HIF-1α, HIF-2α, erythropoietin (EPO) and carbonic anhydrase IX (CA9) were assessed by immunohistochemical staining of ccRCC paraffin blocks from 123 patients using the tissue microarray technique. The expression level of FBP1 was then correlated with various clinicopathological factors, and the protein expression levels of HIF-1α, HIF-2α, EPO and CA9. Clinicopathological factors, including age, gender, T stage and Fuhrman grade, were not significantly different between patients with low and high FBP1 expression in ccRCC (P>0.05). FBP1 protein expression level was significantly correlated with the expression levels of HIF-1α (P=0.005) and EPO (P=0.010), but not significantly correlated with the expression levels of HIF-2α (P=0.123) and CA9 (P=0.513) in ccRCC tissues. The current findings confirm the association between FBP1 and hypoxia-related gene expression, and may facilitate understanding of the mechanisms of ccRCC tumorigenesis.
