Three new Stenus species of the cirrus group collected from Guizhou Province, southwest China, are described: S. dashaheensissp. n., S. zhangyuqingisp. n., and S. liuyixiaoisp. n. The diagnostic characters of the new species are illustrated, and a key to species of the group from Guizhou Province is provided.

Adhesion molecule CD146 and its soluble form correlate well with carotid atherosclerosis and plaque instability.

AIMS: Intraplaque neovascularization and foam cell infiltration contribute to the development of unstable plaque, leading to thromboembolism and stroke. Cell adhesion molecules (CAMs) have been reported to be involved in the progression of atherosclerosis and plaque vulnerability. The aim of this study was to assess the association of adhesion molecule CD146 with carotid plaque instability. METHODS: We collected forty atherosclerotic plaques from 40 patients undergoing carotid endarterectomy. The clinical information of each patient was obtained, and the plaque morphology and characteristics were examined by the ultrasound. The CD146 expressions of the plaques were graded by using semiquantitative scales. The serum level of soluble form of CD146 was detected by enzyme-linked immunosorbent assay (ELISA). RESULTS: CD146 expression was mainly on the intraplaque blood vessels and infiltrated macrophages. The CD146 expression was strongly correlated with the matrix metalloproteinase-9(MMP-9)expressions (P < 0.001) in the plaques. Soluble CD146 (sCD146) was also elevated in patients with atherosclerotic plaques. There was significant correlation between the increased CD146 expression and sCD146 level (P = 0.0057). sCD146 correlated well with serum MMP-9 (P < 0.0044), IL-6 (P = 0.0044) and high sensitivity C-reactive protein (hsCRP) (P = 0.005). CONCLUSIONS: Adhesion molecules CD146 and its soluble form strongly correlated with the development of inflammation of atherosclerosis and plaque instability. CD146 may be a promising biomarker for monitoring the development and instability of atherosclerotic plaque in patients with carotid diseases.

[The ultrastructure of compound eye in the Portunus tritubereulatus under different wavelength lights adaptation].

The fine structure of compound eye in Portunus tritubereulatus under different wavelength lights adaptation was studied with electron microscopy. The Portunus tritubereulatus were trained in a darkroom for 30 minutes and they were given the lights of different wavelength (red 750 nm, yellow 580 nm, green 560 nm, blue 400 nm). The result showed that fine structures varied with different wavelength lights. Under red light, the diameter of rhabdom was biggest, the microsvilli was orderly. There were more endoplasmic reticulum and mitochondria in the cell. The pigment granules were distributed everywhere in the cytoplasm. The dimension of perirhabdomal vacuoles was small. Under blue light, the diameter of rhabdom was smallest, the microsvilli was messy. There were more lamellar bodies, lysosomes and perirhabdomal vacuoles in the cell. The pigment granules were distributed around nucleolus.
