Objective To reconstruct skin defects with local flaps after resection of tumors. Methods From October 2006 to December 2009, medial canthal defects in 15 patients were repaired with local flaps in the hospital. The size of the defects varied from 1 cm × 1 cm to 1.8 cm × 2.0 cm. According to the size and location of the defects, different local flaps such as glabellar flaps ,rotation flaps, advancement flaps, nasolabial flaps and combination of these local flaps were selected and designed to repair the skin defects. Results Of the 15 patients, 12 received the reconstruction of skin defects with single flap, the other 3 with two flaps; totally,18 local flaps were designed and applied. All the flaps survived with primary healing postoperatively. A followup in 11 patients for 6 to 12 months showed that the color and texture of flaps were similar to those of surrounding tissues and incision line scar was inconspicuous. Medial canthal contours were restored without distortion of surrounding structures. Satisfactory function and aesthetic outcomes were achieved. Conclusions In the repair of inner canthus skin defects, to maintain and restore the "cosmetic unit" integrity of inner canthus by using suitable local flaps would lead to a satisfying restoration of function and appearance.

ObjectiveTo study the relevant effect of proinflammatory cytokines interelenkin-17(IL-17), -6 and endothelin-1 (ET-1) on statins attenuating no-reflow phenomenon after myocardial ischemia-reperfusion in rats.MethodsEighteen healthy male Wistar rats were randomly divided into 3 groups according to body weight: sham operation, injury, preconditioning groups. The preconditioning group was given atorvastatin 2 mg·kg-1 ·d-1 and the other two groups were given the same volume of saline once. After 7 days, the rats were anesthetized with an intraperitoneal injection of chloral hydrate, and then the thoracic cavity was opened. The coronary artery of injury group and preconditioning group were ligated for 60 minutes, and then opened for 15 minutes, to establish the rat acute myocardial ischemia-reperfusion model. The sham operation group was was treated with a seam through the coronary artery without ligation. Eleetrocardiogram was checked before ligation, and ligation was carried out for 15, 30, 45 minutes and then reperfusion for 15 minutes. After reperfusion for 15 minutes, the thioflavine S and Even's were injected from femoral venous, then the heart and blood were obtained(keeping left ventricular only). Hearts were flushed with saline and sliced transversely into five to seven sections. Finally, observed at 365 nm wave length the existence of non-fluorescent areas, which was no-reflow zone. The level of serum IL-17, IL-6 and ET-1 was detected by ELISA. Results The electrocardiogram confirmed that the sham operation group had no ischemic damage and the model of myocardial ischemia- reperfusion was established in preconditioning group and injury group. The noreflow phenomenon could be observed under 365 nm wave length in preconditioning group and injury group. The ligated area[LA%, (57.34 ± 11.49)%, (53.08 ± 8.66)%] of injury group and preconditioning group was higher than that of sham operation group(0, all P < 0.05); the area of no-reflow[ANF%, (48.96 ± 6.94)%, (21.37 ±3.35)%] of injury group and preconditioning group was higher than that of sham operation group(0, all P < 0.05),and the ANF% of preconditioning group was lower than that of injury group(P < 0.05) ; the level of serum IL-17,IL-6 and ET-1[(151.67 ± 11.19) × 10-9, (167.89 ± 5.13) × 10-9, (322.37 ± 19.08) × 10-9 g/L] of injury group was higher than those of sham group and preconditioning operation group[(49.75 ± 14.06) × 10-9, (59.32 ± 5.26) ×10-9, (109.9 ± 12.12) × 10-9, (90.45 ± 11.63) × 10-9, (112.47 ± 10.40) × 10-9 and(198.91 ± 27.88) × 10-9 g/L,P < 0.05], the level of serum IL-17, IL-6 and ET-1 of preconditioning group was higher than those of sham operation group(P< 0.05). Conclusionsno-reflow phenomenon is related with IL-17 and ET-1 which can promote the expression of IL-6, statins decreases the expression of IL-17 and ET-1, and then decreases the on-reflow phenomenon.
