1.The Peroxiredoxins protein family and related disease
Journal of Medical Postgraduates 2015;(1):98-101
Peroxiredoxins(Prxs) are a family of antioxidant protein that have been identified in prokaryotes and eukaryotes. As antioxidants, Prxs protein contains an active site cysteine that is sensitive to oxidation by H 2 O2, eliminate active oxygen that exist in normal tissues and cells, protect cells from oxidative damage induced by reactive oxygen species ( ROS). Prxs protein is a known free radical scavenger, and has been shown to play a role in several diseases. In this review, recent advances on the study of Prxs protein family and tumor related diseases are reviewed, which is expected to provide new ideas for the diagnosis and treatment of the related clinical diseases.

Objective:To investigate the third molar horizontal and vertical drift automatically after the second molar extraction.Methods: 26 patients,aged 11~18 years old, with the indications of second morlar extraction were divided into two groups:15 cases in experimental group with the extraction of the second molar and 11 in control group without the extraction. A cephalometric radiograph of each patient was traced on before and 9 months after treatment. Vertical and horizontal drift and mesio- angulation of the third molar were measured.Results:The third molar vertical mesio-movement (mm)in experimental and control groups was 7.08?2.04 and 2.09?0.47(P

Objective To observe the hemodynamic change of small artery in patients with type 2 diabetes. Methods We measured peak systolic velocity (PSV), end-diastolic velocity (EDV), pulse index (PI), resistance index (RI) of ocular artery (OA), central retinal artery (CRA), finger artery, dorsal pedis artery and interlobar artery of patients with early-stage type 2 diabetes. Results The decrease in PSV and EDV values occurred early in CRA of type 2 diabetics while RI and PI values increased. Conclusion The hemodynamic change of CRA occurs earliest among general small arteries of type 2 diabetic patients.

AIMTo study the protective effect of sodium oxybate (SO) against focal cerebral ischemia-reperfusion injury in rats, and the relationship between the effects of SO and ?-aminobutyric acid (GABA). METHODSThe reversible middle cerebral artery occlusion (MCAO)model in rats was established to investigate the role of SO. The scores of neurological deficits was detected by Longa EZ method in MCAO rats. The extracellular levels of glutamate (Glu) and GABA in CSF were measured by high performance liquid chromatography-fluorometer (HPLC-FR) method, and the weight of cerebral infraction was detected. RESULTSThe scores of neurological deficits and the weight of cerebral infraction markedly decreased by SO while the ratio of GABA/Glu obviously increased administered SO in MCAO rats. CONCLUSIONSSO could prevent MCAO rats from ischemia-reperfusion injury, the protective effect is related to SO keeping dynamic balance of excition-inhibition, and persisting inhibition-depended effect.

Objective To evaluate the effect of exogenous nitric oxide (NO) on Schistosoma japonicum in mice. Methods The emulsion of nitric oxide was performed by the reversal emulsifying method and beeswax was used as an agent absorbing NO. Each mice on the day 22 post-infection with cercariae was orally administracted with exogenous NO emulsion 0.5 ml once a day for five days. The worms of Schistosoma japonicum were collected by perfusion and counted to observe the effect of exogenous NO on Schistosoma japonicum. Results The concentration of exogenous NO was 536.2 ?mol/L. Exogenous NO could reach certain therapy efficacy with the worm reduction rate of 45.0% and the egg reduction rate of 42.7%. Conclusion Exogenous NO may be considered as a novel medicament of schistosomiasis japonica.

Objective To study the anti-cancer constituents from Tripterygium wilfordii. Methods Chemical constituents were isolated by repeated column chromatography (silica gel, Toyopearl HW-40 C and preparative HPLC), their structures were elucidated on the basis of spectroscopic methods, and the anti-cancer activity was screened by MTT method. Results Five diterpenes, 3-epi-triptobenzene B (Ⅰ), 3?, 14-dihydroxy-abieta-8, 11, 13-triene (triptobenzene B,Ⅱ), wilforol E (Ⅲ), triptohairic acid (Ⅳ), and 11-hydroxy-14-methoxy-18(4→3)-abeo-abietan-3, 8, 11, 13-tetraen-18-oic-acid (hypoglic acid, Ⅴ) were isolated from T. wilfordii. Conclusion Compound Ⅰ is a new compound named as triptobenzene L, compound Ⅳ is isolated for the first time. The compounds Ⅰ-Ⅴ show the positive anti-cancer effects on HeLa and L929 cell lines.
