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 evaluate the treatment method and time for congenital dacryocystitis.Methods The data about the treat ment massage of Congenital dacryocystitis was analyzed.Results 117 eyes of congenital dacryocystitis in 76 patients were given therapy,of which 5 eyes(5%)were cured by dacryocystitis massage,13 eyes(11%)were cured by dacryosolen lavage,99 eyes were cured by dacryorhinocystotomy,with the cure rate of 85%.Conclusion Dacryorhinocystotomy was an effective and important method to treat congenital dacryocystitis.The age from 2 months to 6 months old are available for treatment of Congenital dacryocystitis.

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.

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 evaluate the reporting quality of Meta-analyses published on Chinese journals of geriatrics.Methods Papers of Meta-analyses on geriatrics published in nine major Chinese journals of geriatrics before November 21,2013 were retrieved,their basic information were abstracted and evaluated through system assessment and preferred reporting items for systematic reviews and Meta-analyses (PRISMA) statement.Statistical analyses were performed with the SPSS17.0 software.Results Among the 71 internalized papers,1 was from 《Geriatrics & Health Care》,1 from 《Practical Geriatrics》,10 from 《Chinese Journal of Geriatric Care》,45 from 《Chinese Journal of Gerontology》,3 from 《Chinese Journal of Multiple Organ Diseases in the Elderly》,1 from 《Chinese Journal of Geriatric Dentistry》,5 from 《Chinese Journal of Geriatric Heart Brain and Vessel Diseases》,5 from 《Chinese Journal of Geriatrics》.55 papers (77.5%) were published in recent 3 years.The mean overall PRISMA score was(16.75±3.04)ranged from 4 to 24.The main influencing factor for the quality of Meta-analyses was the year of publication (adjusted β=-0.342,P=0.003).Conclusions The quantity and quality of Meta-analyses published on Chinese journals of geriatrics are increased and improved in recent years,but there are still some problems on the writing norms.We should promote PRISMA statement and standardize reporting format to improve the quality of Meta-analyses in the field of geriatric medicine.

Objective To investigate the different distribution and expression of mammalian target of rapamycin complex (mTORC) in the kidney of diabetic nephropathy (DN) mice.Methods Fourteen eight-week-old male C57BL/6 mice were assigned to 2 groups: the control group ( n=7 ) and the streptozotocin ( STZ )-induced DN group ( n=7 ) . Blood and urinary variables including glucose , albumin, creatinine and albumin/creatinine ratio were assessed 2 weeks after STZ injection.Hematoxylin-eosin staining was performed for renal pathological analyses .The distributions of mTOR , phosph-ser2448-mTOR(p-mTOR), mTORC1(Raptor), mTORC2(Rictor) and phosph-ser240/244-S6K1 (p-S6K1) were determined by immunofluorescence.The expression levels of mTOR, p-mTOR, mTORC1(Raptor), mTORC2(Rictor), S6K1 and p-S6K1 were detected by Western blotting .Results Two weeks after STZ injection , the diabetic mice developed albuminuria (P<0.01) and renal hypertrophy (P<0.05).The immunofluorescence positive staining for mTOR , Raptor, and Rictor was distributed in the epithelial cells of proximal tubules , glomerular mesangium and capillary loops as well as the medullary collecting ducts of the control mouse kidney .These positive signals increased in the DN mouse kidney ( P<0.05).However, pS6K1 was not detected in the inner medulla of control mouse and p-mTOR was not found in the glomeruli of both control and DN mice .Conclusion mTORC is widely expessed in the mouse kidney and participates in the development of DN , whereas the 2448 serine phosphorylation of mTOR may be not implicated in the hyperglycemia mediated glomerular injury .
