Objective To discuss the MSCT performances of appendix mucinous cystadenoma in order to improve the preoperative diagnosis.Methods MSCT plain and enhanced findings of mucinous appendix mucinous cystadenoma proved by pathology in 6 pa-tients were analyzed retrospectively.Results CT showed cystic dilatation of the appendix in 2 patients with heterogeneous density, and cystic mass in the right iliac fossa in 4.As for the cystic wall,uniform thin wall was seen in 4,curvilinear mural calcification in 3 and septation in 2.Dynamic enhanced CT showed the ring mural enhancement in 4.In addition,the blurred surrounding fatty tis-sues were seen in 2.Conclusion MSCT findings of mucinous appendiceal cystadenoma appeared as cystic dilatation or cystic mass in the right iliac fossa,curvilinear mural calcification and enhanced wall.

Object To analyze the rDNA ITS sequences between wi ld plants and cultivars of Trapa L. and study the utility in p hylogenesis and identification of these two groups. Methods The ITS gene fragments were PCR amplified and sequenced. The rDNA ITS regions w ere analyzed by means of the software of Clustal and Mega 2.0. Result s The rDNA sequences of 234-236 bp ITS1, 220-221 bp ITS2 gene fragment , and 5.8 S rDNA for 164 bp evenly were obtained from ten populations of Trapa L. The intraspecific substitution varies from 0.22% to 2. 94%. The variable sites are 16 while informative sites are six. The phylogenet ic tree based on ITS data was set up by NJ method. Conclusion ITS sequence is a pretty good molecular marker which can identify wild plants of Trapa L. from their cultivars. Diversity of ITS in differen t populations is less at intraspecific level. It is infered that the plants of Trapa L. may be derived from the same population of one species .

Purpose To investigate effect of valsartan on expression of Notch pathway and production of extracellular matrix. Methods Urine protein and production of extracellular matrix were measured after diabetic mice were treated with valsartan. The levels of Jag-ged1, Notch1, Notch intracellular domain 1 (NICD1), transforming growth factor-β1 (TGF-β1), TypeⅣcollagen and Laminin were determinated by immunohistochemistry, Western blot and real-time PCR. Results Valsartan suppressed urine protein and production of extracellular matrix in diabetic mice (P<0. 05). Valsartan also inhibits overexpression of Jagged1, Notch1, NICD1, TGF-β1, Type Ⅳ collagen and Laminin in glomerular tissues of diabetic mice (P<0. 05 or P<0. 01). Conclusion Valsartan inhibits activa-tion of Notch pathway in glomerular tissues of diabetic mice, inhibits production of extracellular matrix in glomerulus and delays glomer-ulosclerosis.

Objective Improve the level of education of medical information to promote faster and better development of medical information.Methods According to the disciplinary development lag,weak teachers' drawbacks of medical education and medical information technology status quo,research talent development solutions.Results Departure from the practice of medical information is proposed to establish and improve the incentive mechanism,curriculum system and teaching content changes,the establishment of hospital information system simulation laboratory recommendations.Conclusion For the development and maturation of the education of medical information,to promote the cultivation of medical information,certain referential significance.

AIM: To explore the effect of hypertonic sugar eyes drops with local to the oxygen therapy for severe corneal edema after cataract surgery.METHODS: Totally 68 patients (68 eyes) with severe corneal edema after phacoemulsification were selected from January 2014 to December 2015 in our hospital, who were aged 53-80(64.45±4.24), including 30 males and 38 females.According to different treatment, they were divided into treatment group (34 cases) given conventional therapy + hypertonic sugar eyes drops with local to the oxygen therapy, the control group (34 cases) given conventional treatment + hypertonic sugar eyes drops.Visual acuity and corneal situation were observed during the treatment.RESULTS: Corneal edema fade time of treatment group was 11.62+0.53d, that of control group was 15.23±0.62d, the difference between the two groups was significant (P<0.05).Preoperative best corrected visual acuity (BCVA) and corneal endothelial cell count had no significantly difference between the two groups while the corneal endothelial cell count were significantly different compared with postoperative of the two groups (P<0.05).At 7d after treatment, the BCVA and corneal endothelial cell count had significantly difference between the two groups (P<0.05), which did not have significant difference at 1mo after treatment (P>0.05).The effective rates of the two groups was significantly different (P<0.05).CONCLUSION: Hypertonic sugar eyes drops with local to the oxygen therapy is effective for severe corneal edema after cataract surgery.

OBJECTIVEPolyethylene glycol/bone morphogenetic protein-2 (PEG/BMP-2) nanoparticles were transfected into Rabbit bone mesenchymal stem cells (rBMSCs) and the expression of BMP-2 was detected.

METHODSDissociated rBMSCs were primarily cultured in vitro and BMP-2 gene was transfected into rBMSCs by PEG/BMP-2 nanoparticals and lipofectamine, respectively. The efficiency of transfection was detected by flow cytometry and the expression of BMP-2 was detected by Western Blot and real time RT-PCR.

RESULTSPEG/BMP-2 nanoparticals were successfully synthesized and transfected into rBMSCs. Compared with the lipofectamine transfection group, PEG/BMP-2 transfection group had higher efficiency and higher BMP-2 expression.

CONCLUSIONPEG/BMP-2 nanoparticals transfected rBMSCs highly expressed BMP-2,which provided novel strategies for the treatment of bone defect.
