Objective To investigate the effects of resistin on mesangial cells proliferation induced by high glucose and subsequent change of p38MAPK signal pathway. Methods Human macrophrages were cultured and treated with adenovirus encoding for resistin (Ad-resistin) for 48 h and were then co-cultured with human mesangial cells stimulated by high glucose for another 48 h. Mesangial ceils were harvested and their proliferation was measured by 3H-TdR. Activator protein 1 (AP-1) was examined by immunocytochemistry and laminin of excellular matrix was observed with immuofluorescence. Protein levels of p38MAPK and TGF-β1 were measured by Western blot. Smad2 phosphatase activity was aslo detected by Western blot. Results The mRNA and protein levels of resistin were significantly higher in Ad-resistin treated macrophages than those in Ad treated cells (P<0.01). Over-expression of resistin up-regulated p38MAPK protein levels of human mesangial cells(P<0.05). Resistin also promoted the proliferation of mesangial cells (P<0.01) and the synthesis of laminin stimulated by high glucose. The expression of TGF-β1 and phosphorylation of Smad2 were up-regulated in the mesangial cells (P< 0.05). Conclusion Macrophage cytokine resistin may promote mesangial cells proliferation and abnormal accumulation of excellular matrix stimulated by high glucose via activating p38MAPK signal passway.

Background Measurement of ciliary sulcus distance is important for phakic intraocular lens implantation.Suowei panoramic 50-MHz digital ultrasound biomicroscopy makes it possible for the direct measurement of ciliary sulcus distance.Objective The aim of this study was to investigate the correlation between anterior chamber(AC)angle diameter and ciliary sulcus distance in different AC depth population and offer a clinical guide.Methods The anterior chamber angle diameter and ciliary sulcus distance were measured in 30 right eyes with shallow anterior chamber caused by suspect glaucoma and 30 right eyes with deep anterior chamber dut to the high myopia with Suowei panoramic 50-MHz digital ultrasound biomicroscopy.Three horizontal B-scans with the focal plane approximately at a depth corresponding to the iris plane were acquired for each eye.The differences of the anterior chamber angle diameter and ciliary sulcus distance were calculated and compared between the two groups.The correlation of the anterior chamber angle diameter and ciliary sulcus distance were evaluated in respective group.Results In shallow AC group,the mean angle diameter was(11.49+0.75)mm,the mean ciliary sulcus distance was (10.97±0.86)mm with the mean standard deviation of the difference of(-5.14± 0.55)mm,showing a statistically significant difference(t =-5.092,P =0.000).In shallow AC group,linear regression analysis showed a statistically significant correlation between ciliary sulcus distance and angle diameter(R2=0.593,P=0.000)and the Pearson's correlation coefficient was 0.767.In deep AC group,the angle diameter was(12.69±0.67)mm;while ciliary sulcus distance was(12.31 ± 0.61)mm with the mean slandard deviation(-0.38 ± 0.17)mm,which was statistically significantly different(t=-5.531,P=0.000).The ciliary sulcus distance was found to be linear correlation with the angle diameter(R2 =0.699,P=0.000)and Pearson' s correlation coefficient of 0.836.Conclusions Panoramic ultrasound biomicroscopy is an useful tool to the measurement of ciliary sulcus distance.This study exhibited that the ciliary sulcus distance is significant associated with the anterior chamber angle diameter,which may offer a guide for phakic intraocular lens implantation.

OBJECTIVE: To analyze the general and forensic pathological characteristics of death due to fat embolism syndrome (FES) and to provide reference data for forensic identification. METHODS: Twenty autopsy cases due to FES were selected from the forensic center of a medical college from 1999 to 2012. The general and forensic pathological characteristics such as the ways and types of injuries, clinical manifestation and the pathological changes were summarized. RESULTS: Fat embolism mainly occurred after long bone fracture or a large area of soft tissue injury with the majority of cases being fat embolism of lung and occasional cases being combined embolisms of lung and brain as well. The onset of symptoms appeared shortly after the injury or surgery. Lipid droplets could be observed within small pulmonary vessels and verified by special staining. CONCLUSION There are particular characteristics in death due to FES in concern with types of injuries, onset of symptoms and pathological findings. In order to find out the direct evidence of FES, special staining (oil red O staining) can be used in the forensic identification.
