We used near-infrared spectroscopy technology to monitor and assess the treatment effect of dehydrating agent in injured rat brain in real time style. We employed the brain edema model in rats resulting from Feeney' s freefall damage, then treated with different doses of mannitol, and collected reduced scattering coefficient (p',) and intracranial pressure (ICP) values after the injury and during the treatment. The results showed that brain edema happened 1 h after the injury in rats' brain tissue, peaked around 72 h after injury, and then began to decrease gradually. The reduced scattering coefficient and ICP values of the treatment group injected with mannitol all decreased after administration. Compared with the effect of low-dose mannitol treatment, that of high-dose mannitol treatment was much better. The duration of the plateau was longer and most experiments results declined significantly. From this we conclude that the reduced scattering coefficient and ICP are consistent with the trend changes, and the reduced scattering coefficient could be used as an indicator for monitoring cerebral edema.

Objective To investigate the causes of visual disability and to evaluate the curative effect of visual disability aids test paired for improving the visual function in the patients with visual disability.Methods By adopting the visual acuity disability rating standards in the 2006 second national disabled sampling survey,100 patients with visual disability undergoing fitting visual aids in the ophthalmology department of the Second Affiliated Hospital of Chongqing Medical University were selected.The causes of visual disability were identified by means of ophthalmological examinatiom at the same time wearing far or near low vision aids observed the improvement degree of eyesight.Results The first cause of visual disability was retinal disease(25.00％).In wearing the distant visual aids,the off-blindness rate was 94.59 ％ and the off-disability rate was 82.43 ％;after wearing the near visual aids,the cases of near visual acuity≥0.50 accounted for 92.31％.Conclusion Retinopathy is a leading cause of adult vision disability;the aids for visual disability in the patients with visual rehabilitation have remarkable curative effect,and can improve the quality of life in the patients with visual disability.

Objective To analyze the influence of mode of delivery on post-neonatal gut microbiota using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technology.Methods From April to August in 2013,thirty healthy urban full-term neonates in Nanjing City were enrolled in the study,including fifteen exclusive breastfed ones (seven born of caesarean section and eight born vaginally) and fifteen mixed feeding ones (eight born of cesarean section and seven born vaginally).Stool specimens were collected on the 28th day after birth and bacterial genomic DNA was extracted and examined by PCR on 16S rDNA V3 variable region.Bacterial community profiles were obtained by DGGE.Diversity and similarity differences of the gut microbial community structures were analyzed.Two independent sample t test or Chi-square tests were used for stastistical analysis.Results (1)Diversity analysis showed that among exclusive breastfeeding infants,the Strip number and Shannon-Weaver Diversity Index of gut microbiota in infants born abdominally were significantly lower than those born vaginally [9.71 ±4.27 vs 15.12±4.19,2.13±0.39 vs 2.61±0.32,both P＜0.05],but the Simpson index of gut microbiota was significantly higher [0.13 ± 0.04 vs 0.08± 0.03,P＜0.05],and no significant difference was shown in Pielou Index (P＞0.05).In the mixed feeding group,the Strip number and Shannon-Weaver Diversity Index of gut microbiota in infants born abdominally were significantly lower than those born vaginally [10.88±3.23 vs 16.29±5.38,2.26±0.37 vs 2.66±0.31,both P＜0.05],the Simpson index was higher,but together with the Pielou Index,neither showed significant difference (both P＞0.05).(2) Similarity analysis found that gut microbiota from neonates born of same mode of delivery mostly gathered together and had much more similar structures.Conclusions In the post-neonatal period,the species and numbers of gut microbiota in infants born abdominally are all behind of those born vaginally.The predominant microbiota in babies born of cesarean section are more prominent,and gut microbiota in vaginal delivered babies are more uniformly distributed.

Objective To detect the change of CD47 on T-lymphocyte subsets marked by CD3 + CD4+ and CD3+ CD8+ in the acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore its clinical significance.Methods The peripheral blood of 30 patients was collected before and every two weeks from hematopoietic reconstitution after allo-HSCT.The expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was detected by flow cytometry,and the relationship between their expression and the occurrence of aGVHD was analyzed.Results The percentage of CD3+ CD4+-and CD3+ CD8+-marked T-lymphocyte subsets showed no statistically significant difference between aGVHD group and non-aGVHDgroup [(38.95 ± 6.18)％ vs.(37.38 ± 4.6)％,and (22.35 ± 3.32)％ vs.(20.34 ±4.56) ％,respectively] (P＞0.05).The expression levels of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was obviously increased in aGVHD group when compared to before transplantation and non-aGVHD group after transplantation,and that had no changes in non-aGVHD group when compared to before conditioning regimen after transplantation.Mean fluorescence intensity of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ [(93.70 ± 14.88) and (70.09 ± 12.51)] in aGVHD group significantly increased as compared with non-aGVHD group [(71.27-± 11.32) and (53.93 ± 8.35)] (P＜0.05).There was no significant difference in the expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ before and after transplantation in non-aGVHD group (P＞0.05).Moreover the expression of CD47 on T-lymphocyte subsets marked by CD3 + CD4 + and CD3 + CD8 + changed correspondingly with the outcome of aGVHD in aGVHD group.Conclusion The change of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ andCD3+ CD8+ is valuable to monitor the aGVHD after allo-HSCT,which may provide a new means for the early detection of aGVHD.

Objective To evaluate the clinical effect of different oral care solution.Methods Literature data were collected by computer retrieval covering China National Knowledge Infrastructure (CNKI),China Biology Medicine (CBI) and Wanfang database,and Note Express and Addis software were used to evaluate the randomized controlled trials of literature.Results 19 separate randomized controlled trials were included in the research hterature;Network Meta analysis results showed that in the prevention of ventilator-associated pneumonia,the electrolyzed oxidizing water,compound chlothexidine,hydrogen peroxide,sodium bicarbonate,distilled water and 0.9％ saline had statistically significant difference (OR=0.25,95％CI=0.02-0.72),and the effect of sodium bicarbonate was better than the other oral care solutions;in the prevention of oral odor,the oral care solution had no significant difference (OR=0.86,95％CI=0.34-1.74),and sodium bicarbonate of the total ranked the best preventive effect;in the prevention of oral infection,the oral care solution had no significant difference (OR=0.62,95％CI=0.09-1.60).Conclusions Based on the meta analysis results,with 0.9％ saline for common interventions,sodium bicarbonate oral nursing liquid is superior to other oral nursing liquid in the prevention of ventilator-associated pneumonia,oral smell and infection.

Objective To discuss the impact of an iterative reconstruction algorithm (True X) implemented with point spread function (PSF) on image quality and SUV in 18F-FDG PET, and compare with other reconstruction algorithms.Methods A total of 79 hypermetabolic lesions from 37 cancer patients (23 males, 14 females, age (63.38±15.25) years) were retrospectively studied.The PET images were reconstructed using the following six reconstruction algorithms, including FBP, FBP+TOF, iteration, iteration+TOF, True X, True X+TOF.Paired t test was used for statistical analysis.Results All six reconstruction algorithms showed significant difference in lesion SUVmax.The adoption of PSF increased SUVmax by 15%-16%, and decreased the dispersion of SUV in the liver parenchyma remarkably.Conclusions Lesion SUVmax calculated from different reconstruction algorithms has significant differences.Caution should be taken in using PSF, as it can improve image quality but may also increase lesion SUVmax.
