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.

BACKGROUND: Taohong Siwu Tang is made up of Taoren, Honghua,Danggui, Chishao and Chuangxiong. Paeoniflorin is one of the major effective components in Radix Paeoniae Rubra Extracts and Taohong Siwu Tang, and it can promote blood circulation and remove blood stasis and has the effect of anti-acute myocardial ischemia.OBJECTIVE: To compare the serum concentration of paeoniflorin in mice after intragastric administration (i.g.) of Radix Paeoniae Rubra extracts and Taohong Siwu Tang.DESIGE: Rndomized controlled observation.SETTING: Department of Pharmacy and Department of Basic Medicine,Hebei North University.MATERIALS: The trial was performed in the first laboratory of Department of Pharmacy, Hebei North University during February to June 2005.Eighty involved Kunming mice of either gender and of clean grade, with body mass of 18 to 22 g, were purchased from Experimental Animal Center, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences. Taoren, Honghua, Danggui, Chishao, Shengdi and Chuanxiong 6 Chinese herbs were all purchased from Zhangjiakou Institute of Traditional Chinese Medicine.METHODS: ①Blank serum was isolated from eight mice which were fasted for 12 hours. Control sample solution of paeoniflorin was added into blank serum. Acetonitrile was used to deposit protein, the solution was centrifugated and isolated ,and 20μL supernatant was taken to obtain regression equation. ② Seventy-two Kunming mice were randomized into Radix Paeoniae Rubra extracts group and Taohong Siwu Tang group, with 36 mice in each. After being fasted for 12 hours, the mice in each group were intragastric administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang, respectively and the concentration of paeoniflorin was 300 mg/kg.1 mL blood was taken respectively at 15, 30, 60, 90, 120 and 180 minutes after intragastric administration and prepared into serum sample (6 mice at each time point in each group). The time to peak and difference in peak concentration of serum paeoniflorin were compared between intragastric administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang.The concentration of paeoniflorin was measured with high-performance liquid chromatography (HPLC). Chromatographic condition: chromatographic column YWG-C18 (250×4.6 mm,10 μm). The mobile phase was methanolKH2PO4 (0.05 mol/L) (38∶62) at a flow rate of 1.0 mL/min. The detective wavelength was set at 230 nm. The column temperature was 25 ℃.MAIN OUTCOME MEASURES: Serum concentration of paeoniflorin after administration of Radix Paeoniae Rubra extracts and Taohong Siwu Tang in mice.RESULTS: Seventy-two mice were used for Radix Paeoniae Rubra extr acts and Taohong Siwu Tang tests, and all of them entered the stage of result analysis without deletion. ① Chromatographic isolation results: Paeoniflorin could be well isolated from other components. The linear range for detection of paeoniflorin was 5.40-646.0 μg/mL. The mean recovery rate was 93.6% and the limit of detection was determined as 1.08 mg/L. ②Comparison of concentration of serum paeoniflorin of mice between two groups: The concentration of serum paeoniflorin in the Radix Paeoniae Rubra extracts group and Taohong Siwu Tang group reached the peak at 30 and 60 minutes after intragastric administration, respectively. The peak concentration of paeoniflorin of Taohong Siwu Tang group was lower than that of Radix Paeoniae Rubraextracts group [(36.27±5.72) mg/L vs.(46.82±5.29) mg/L, P ＜ 0.01 )].CONCLUSION: The concentration of serum paeoniflorin is significantly decreased after intragastric administration. It was further confirmed the decreased concentration of the crude paeonifiorin in the mice sera might result from promotion of its metabolic conversion by other chemical components in the complex prescription. This result needs further investigation.
