BackgroundThere are a lot of studies about the wound healing charateristics of cornea after SBK with femtosecond laser.In our study,mechanical microkeratome was preferred for corneal flap.We observed the proliferation of keratocytes by investigating the myofibroblast ( MF) activity.Objective The study was to compare the morphologic and histological changes in the cornea after sub-Bowmans keratomileusis ( SBK) with photorefractive keratectomy ( PRK) and laser in situ keratomileusis ( LASIK)by investigating the express of transforming growth factor-β( TGF-β)and α-smooth muscle actin( α-SMA)and to investigate the wound healing characteristiCs of cornea after SBK.MethodsTwenty-seven adult New Zealand white rabbits were randomly assigned into group A,B and C.SBK waa performed on the right eyes of each rabbit in group A,LASIK for group B and PRK for group C.All the left eyes were used as the normal control group.Histological examinations by light microscopy were performed on day 7,1 months,3 months after surgery.The expression of α-SMA and TGF-β and the number of activated MF were assessed by immunohistochemiatry.ResultsIn SBK group,corneal epithelium cells proliferation around the wound was seen and the numbers of active fibroblasts were increased after surgery.The expression of α-SMA or TGF-β around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed t3mnh.TFβep( SBK:t=2.226,2.158,2.330,P＜0.05;PRK:t=4.745,6.524,6.293,P＜O.05).The numbersof activ( SBK:t=2.226,2.158,2.330,P＜O.05;PRK:t=4.745,6.524,6.293,P＜0.05).The numbersof activatedMFs were different fromLASIKstatisticallytoobetweenSBKgroupandPRKgroup ( SBK:t =4.439.5.692,4.175,P＜0.05 ; PRK:t=6.330,6.723,5.267,P＜0.05 ).Theα-SMAand TCF-βexpressionsin SBKgroupwerelessthan PRK group but more thanLASIKgroup( TCF-β:t =4.691,5.527,t =4.399,P＜0.05 ; α-SMA:t =9.637.10.282,8.197,P＜0.05).The numhers of MFs in SBK group was less than PRK group before 3 months and were same at 3 months ( t =5.188,4.529,P＜0.05 ).Conclusions ComparedwithconventionalLASIK,SBKcanup-regulatethe expression of α-SMA.TGF-β,activated MFs in the corneal flap.which enhance corneal biomechanics and promote healing.However,most of the disadvantages caused by wound healing in SBK still remain compared to PRK.

Objective To explore the relationship between obesity and the various parameters of physical fitness and provide the basis of physical fitness management for people.Methods A total of 725 male college students recruited from a University in Yangzhou.Height,weight,waist circumference and physical fitness of the subjects were measured.According to Obesity criteria (BMI and/or WC) ,the college students were divided into the following 4 groups(BMI obesity group(BOG),WC obesity group(WOG),BMI and WC obesity group(BWOG) and normal group(NG)).Logistic regression analysis was used to explore the relationship between obesity and physical fitness.Results (1) Significantly,1500m (P<0.01) of BWOG,BOG and WOG,push-ups (P<0.01) and standing time on one foot with closed eyes (P<0.01) of BOG and WOG and whole body reaction time(P<0.01) of BOG were lower than that of NG.(2) Vital capacity of BWOG and WOG (P<0.01),and grip strength (P<0.01) and back strength of BWOG and BOG (P<0.05) were higher than that of NG.(3) Multiple logistic regression showed that the odds ratios of WOG(βBOG=-1.002,OR=0.367,95%CI=0.191-0.702,P<0.01) and BOG(βWOG=-1.785,OR=0.169,95%CI=0.038-0.772,P<0.05) for low 1500m subjects were higher,of BWOG(βBWOG=1.776,OR=5.901,95%CI=1.298-26.828,P<0.05) and BOG(βWOG=1.681,OR=5.365,95%CI=1.667~24.670,P<0.05) for high vital capacity subjects were higher, of BOG for subjects of low Push-ups(βBOG=-0.658,OR=0.518,95%CI=0.280-0.960,P<0.05) and whole body reaction time(βBOG=-0.902,OR=0.405,95%CI=0.213-0.775,P=0.005) were higher,of WOG for high back strength(βWOG=-1.583,OR=0.207,95%CI=0.045-0.946,P<0.05) were higher while of BWOG and BOG for high grip strength subjects (βBWOG=1.786,OR=5.974,95%CI=1.315-27.155,P<0.05;βBOG=0.712,OR=2.036,95%CI=1.088-3.806,P<0.05) were higher,as compared to the NG.Conclusions ubjects of BWOG,BOG and WOG show reduced cardiorespiratory,BOG and WOG show lower upper arm muscular endurance and balance.The subjects of BOG show lower agility,BWOG and WOG show increased muscular strength and vital capacity while the subjects of BWOG have higher vital capacity,upper arm muscular and back strength.

Objective To construct a luciferase gene expression vector containing full-length 3' untranslated region(3'UTR)of mouse vascular endothelial growth factor-C(VEGF-C)gene,and to observe the effects of VEGF-C 3'UTR on luciferase gene expression by a double-fluorescence report system.Methods Polymerase chain reaction(PCR)was used to amplify VEGF-C 3'UTR and a 312bp VEGF-C coding region(CR)fragment from full-length VEGF-C cDNA in mouse Lewis lung cancer cells.The luciferase expression vectors containing VEGF-C 3'UTR or VEGF-C CR were constructed by subcloning the PCR products to luciferase reporter vector pGL3-Promoter using gene engineering technology,and then they were transfected to mouse Lewis lung carcinoma cells by LipofectamineTM 2000.The activities and mRNA expression of luciferase were detected by Dual-Luciferase Reporter System and quantitative RT-PCR,respectively.Results Mouse VEGF-C 3'UTR(429bp)and VEGF-C CR(312bp)were successfully amplified by PCR.The VEGF-C 3'UTR and VEGF-C CR fragments were successfully inserted into pTA2 vector,and then subcloned to pGL3-Promoter vector at Xba Ⅰ site by using restriction endonucleases analysis.The DNA sequences and insertion orientation of PCR products were all correct by sequencing analysis.The resulted luciferase expression plasmids were named pGL3-VEGF-C 3'UTR and pGL3-VEGF-C CR,respectively.Dual-Luciferase Reporter System detection and quantitative RT-PCR showed that in Lewis lung carcinoma cells,the activities of luciferase and expression of luciferase mRNA in the pGL3-Promoter group were higher than that in the pGL3-VEGF-C 3'UTR group,and there was no significant difference between pGL3-VEGF-C CR group and pGL3-Promoter group.Conclusion VEGF-C 3'UTR can inhibit luciferase gene expression.

Objective To observe the protective effect of probiotics VSL # 3 on the rats of trinitrobenzene sulphonic acid (TNBS) induced acute colitis, and the effect on the expression of tight junction proteins claudins (claudinl, 2, and 3) in colon mucosa. Methods Rat of colitis model was induced by TNBS one time enema. Since the second day after the model established, 2ml 0.9％ sodium chloride was intragastric administrated into 8 rats each day (TNBS group), 8 rats with 100 mg VSL # 3 (VSL # 3 group ), another 8 rats with 5-aminosalicylic acid (5-ASA) intragastric administration (5-ASA group), and 0.9％ sodium chloride was intragastric administrated daily into 5 no modeling rats as control group. All were treated for 7 days and then sacrificed. Fecal samples were collected for bacterial culturing and detecting the changes of colon bacteria colonies. Disease activity index (DAI was calculated according to diarrhea, hemafecia and weight. The colon tissue was taken for HE staining and the pathological changes were observed under microscope.The changes of myeloperoxidase (MPO) level in colon tissue were examined by enzyme-linked immunosorbent assay (ELISA). The expression and distribution of claudins 1, 2, and 3 in colon tissue was detected by a novel quantum dots immunofluorescence labeling technique. Results Compared with TNBS group,both VSL # 3 and 5-ASA treatment could improve colitis, as well as decreas DAI and colonic MPO level, and lower the inflammatory score of colitis. Compared with control group, the bacteria counting in the colon of colitis rats changed, the expression of Claudins 1, 2, and 3 expression was significantly increased (average density: 66.200±5.737, 71.780±6.670 and 61.300±5. 199,t＝17.237, 27.909and 21.788, all P＜0.01). Compared with TNBS group or 5-ASA group, VSL# 3 could adjust the balance of intestinal bacteria and increase the expression of Claudin 1 and 3 (Claudin 1 : 75. 550 ±8.717, 66.200±5.737 and 67.080±5.401;t＝9.348, 8. 469; all P＜0.05; Claudin-3: 68. 820±7.443, 61.300±5. 199 and 59. 830±5. 930;t＝7. 519, 8. 988, all P＜0.05), however claudin 2 expression was down-regulated (58. 740±6. 457, 71. 780±6. 670 and 66. 870±5. 791; t＝ 13. 033,P＜0.01, t＝8. 123, P＜0. 05). Conclusion Probiotics VSL# 3 may enhance the intestinal mucosal barrier function through changing the claudins expression, and play a role in the relief of inflammatory reaction in acute colitis.
