Objective To investigate the effect of local delivery of paclitaxel on bile duct scar formation and biliary stricture in guinea pig.Methods Models of end-to-end anastomosis of the common bile duct were established in 42 guinea pigs.The animals were randomly divided into paclitaxel and control groups.In the paclitaxel group,the drug solution(1000 ?mol/L,0.05 ml) was smeared onto the anastomotic wound before closing the abdomen.The animals were killed in 3 days,2 weeks,and 1 month after the operation(7 in each group at each time point).The sepcimens of the common bile duct were obtained for histological examination.Transmission electron microscopy was employed to observe the ultrastructure of paclitaxel-induced apoptotic cells.Results Histological examination showed inflammatory reaction and hyperplasia of the bile duct wall.The bile duct wall of the paclitaxel group was significantly thiner than that of the control group in 3 days and 1 month after the operation [3 days:(574.41?24.53)?m vs(802.98?24.42) ?m,t=-6.604,P=0.000;1 month:(1383.36?36.64) ?m vs(1518.56?34.89)?m,t=-2.672,P=0.020].Paclitaxel-induced cell apoptosis and injured cell organs were found by transmission electron microscopy.Conclusion Single local delivery of paclitaxel can inhibit biliary stricture in one month.

Objective: Our purpose was to observe the effect of epithelial scrape injury on corneal morphology. Methods: Twenty 4-week-old white rabbits were used. We scraped the corneal epithelia of the left eye of each rabbit (0.2 mm near the limbus of corneal were left in 10 eyes, in the remaining rabbits within 8 mm in the center). The right eyes were control group. We observed the healing of corneal protrusion with slit-lamp microscope, examined the corneal form with corneal topography, and measured the depth of anterior chamber and the corneal thickness with A-ultrasound. Results: The extensive epithelial scrape significantly increased the healing time. The corneal protrusion of experimental group and the depth of anterior chamber increased. The corneal thickness became thinner. Conclusion: The extensive epithelial injury can make cornea thinner, which results in the changes of corneal protrusion.

Objective To investigate clinical and pathological features of lupus erythematosus profundus (LEP)of the scalp in children.Methods A retrospective study was carried out on 5 children with LEP.The clinical and histopathological features,treatment and prognosis of LEP were analyzed.Results The 5 children with LEP included 2 boys and 3 girls with a median age at onset of 5 months (range,2-38 months) and a median clinical course of 15 months (range,4-72 months).Clinically,the patients presented with arc-shaped or circular purple atrophic plaques on the scalp complicated by alopecia.The occipitalia and tempora were the most commonly involved sites.Antinuclear antibodies (ANA) and extractable nuclear antigens (ENAs) were negative in all the patients.Main histopathological changes were hyaline degeneration of the fat,mucin deposition and local aggregation of lymphocytes in fat lobules.Of the 5 patients,2 were treated with oral prednisone (1.5-2 mg/kg/day),1 with oral hydroxychloroquine (5 mg/kg/day),1 with oral prednisone (1.5 mg/kg/day) combined with hydroxychloroquine (5 mg/kg/day),and another 1 with topical halometasone cream and 0.03％ tacrolimus ointment.Lesions were remissed after 2-3 months of treatment,and subsided with growth of new hairs after 6 months.No recurrence was observed during a 1.5-year follow-up.Conclusion Prednisone and hydroxychloroquine are markedly effective for LEP,and pediatric patients with LEP may be treated by topical highpotency glucocorticoids and calcineurin inhibitors.

Objective: To establish a risk prediction model and scoring system in patients with side branch (SB) occlusion during coronary bifurcation intervention. Methods: A total of 7007 consecutive patients who received percutanenous coronary intervention (PCI) in our hospital from 2012-02 to 2012-07 were recruited and 1545 patients (with 1601 bifurcation lesions) treated by single stent technique or main vessel stenting ifrst strategy were selected for our study. According to weather SB occlusion occurred during operation, the lesions were divided into 2 groups: Non-SB occlusion group,n=1431 and SB occlusion group,n=114. The data set of the ifrst 1200/1601 lesions by time sequence, was used for establishing the risk model and scoring system, the data set of rest 401 lesions was used for model validation. Results: The modeling data set presented that the relationship between pre-operative main vessel plaque and the position of branch vessel, the main blood vessel pre-stenting TIMI grade, the stenosis degree of pre-operative bifurcation nucleus, the angle of pre-operative bifurcation and the ratio of pre-senting stenosis degree of branch diameter and pre-operative main vessel to branch vessel diameter were the independent risk factors for branch occlusion. The risk model ROC=0.80, 95% CI 0.75-0.85, Hosmer-Lemeshow HLP=1.00; the scoring system ROC=0.76, 95% CI 0.71-0.82, HLP=0.12. The validation data set ROC=0.81, 95% CI 0.73-0.89, HLP=0.77; the scoring system ROC=0.77, 95% CI 0.69-0.86, HLP=0.58. The quartile integration of both data sets indicated that the patients with the integration score ≥ 10 had the higher risk for SB occlusion than those with integration score < 10 during the operation,P<0.001. Conclusion: Our research developed a simple and user-friendly system, it may distinguish the patients with high risk of SB occlusion during bifurcation intervention by quantitative stratiifcation of coronary angiographic imaging.

Objective To explore the effect of tumor necrosis factor-alpha(TNF-α) blockade therapy on circulating Th17 cell percentage and serum interleukin (IL)-17 level in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Methods Twenty-seven RA and 22 AS patients were recruited, of which 14 cases from both diseases received 40 weeks TNF blockade therapy. Twenty-four healthy blood donors were used as controls. The frequencies of circulating Th17 cells were determined by flowcytometry, and serum IL-17 level were measured by enzyme linked immunosorbent assay(ELISA). Results Significantly higher baseline circulating Th17 cells were observed in active RA and AS patients compared with the healthy controls[RA 1.03%(0.66%,1.78%) vs controls 0.50%(0.43%,0.67%), Z=-3.236, P<0.01; AS(1.16±0.09)%vs controls (0.59 ±0.061)% , t =5.226, P <0.01]. Similarly, serum IL-17 level were significantly elevated in patients with both diseases compared with controls[RA(32.3±2.5) pg/ml vs controls(14.3±2.5) pg/ml, t=5.070, P<0.01; AS 28.98(23.84,36.14) pg/ml vs controls 11.84(5.33,22.12) pg/ml, Z=-4.103, P<0.01]. After TNF-α blockade therapy, serum IL-17 was significantly decreased in both diseases groups[RA △(-13.5± 5.0) pg/ml and AS △(-16.0±1.9) pg/ml]. In contrast, no significant differences were found in the frequencies of circulating Th17 cells[RA △(0.104 5±0.212 6)% and AS △(0.002 5±0.183 8)%]. Conclusion Th17 cells and IL-17 have been implicated in the pathogenesis of RA and AS. TNF-α blockade can partially inhibit the function of Th17 cells. However, it is unable to reduce the frequencies of these cells in the circulation after 40 weeks therapy, which may explain the reasons for the relapse.
