ABSTRACT

Objective To evaluate the clinical efficacy of ilioinguinal conjoined perforator flap transplantation pedicled with the superficial circumflex iliac artery,the anterior fourth lumbar artery or the posterior intercostal artery.Methods Between April,2005 to August,2015,6 patients diagnosed as large skin defects in the upper extremity were treated with ilioinguinal conjoined perforator flap transplantation pedicled with the superficial circumflex iliac artery,the anterior fourth lumbar artery or the posterior intercostal artery.The proximal flap blood supply was offered by the superficial circumflex iliac artery,and the distal flap blood supply was provided by the anterior fourth lumbar artery or the posterior intercostal artery.The maximal size of the flap was measured as 35.0 cm×15.0 cm,and the minimal size was 25.0 cm×9.0 cm.The donor sites of the flap were directly sutured.All cases were implemented by postoperative followup visit in hospital for observation of appearance,texture,functions and donor site of flaps.Results Postoperatively,all flaps survived.The follow-up time endured for 6 to 24 months.The flap thickness was appropriate with normal shape and soft texture.Protective sensation and perspiration function of the flap were restored.Linear scars alone were observed in the donor sites of the flap.Conclusion Ilioinguinal conjoined perforator flap transplantation pedicled with the superficial circumflex iliac artery,the anterior fourth lumbar artery or the posterior intercostal artery can extend the excision scope of the flap and provides sufficient blood supply for the flap.The flap texture is soft and can be directly sutured.This technique is an ideal option for repairing of large soft tissue defects of the upper extremity.

ABSTRACT

Objective To explore the efficacy of transplantation of a U-shaped ilioinguinal flap in the re pair of skin and soft tissue defects of the extremity.An axial flap based on the superficial iliac circumflex artery and trimmed to a subdermal vascular network flap was used for the procedures.Methods Seven patients with skin and soft tissue defects treated between June,2009 and May,2014 were studied.The patients were 22-45 years of age (mean,32 years),and included 5 males and 2 females.Four patients had punch-press injuries,1 patient had a hot-crush injury,and the remaining 2 patients were injured in the accidents.The wound sizes were 14.0 cm × 10.0 cm to 6.0 cm × 5.0 cm,with a varying extent of exposed tendons and bones.Repairs were performed using free ilioinguinal flaps,which were 15.0 cm × 11.0 cm to 7.0 cm × 5.0 cm in size.The axial flap was trimmed to a U-shaped subdermal vascular network flap and transplanted to the recipient site with anastomosis of blood vessels.Results All transplanted flaps survived.Four patients were followed for 1-6 months,with a mean duration of follow-up of 4 months.The trimmed flaps showed gradual reddening immediately after surgery,and the capillaries were recovered with a flat surface.Re-examination 3 months after surgery showed that the flaps were thin and flexible and met the aesthetic demand.No obvious pigmentation occurred,and the donor site was sutured directly,leaving only linear scars.Conclusion Repair of skin and soft tissue defects of the extremity using a U-shaped trimmed ilioinguinal flap has the advantages of a hidden donor site,small scar,and conformity to aesthetic requirements.The trimmed flaps are preferred over untrimmed flaps in terms of color and texture.The former flap is thinner,meets the aesthetic demand,and achieves a better efficacy.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of iodine supplementation on infant mortality and growth in Xinjiang.</p><p><b>METHODS</b>Urine iodine, height and head circumference (HC) of children aged 5 years in two townships was measured before and yearly after iodine supplementation of irrigation water. Height and HC were expressed as Z scores (United States children used as the reference group). Neonatal and infant mortality rates were obtained from official records in three counties from 1988 to 1999, and analyzed by a logistic regression model.</p><p><b>RESULTS</b>The odds ratio of infant mortality decreased 56.49% and neonatal mortality 65.71% respectively after iodination; there was no significant difference in the odds ratio of infant or neonatal mortality between experimental and control areas without iodination. In Langru township, the mean height of 5 year-old children increased from 95 cm in 1992 to 106.9 cm in 1998 - 1999, and HC from 48.4 cm to 50.5 cm. Median urine iodine increased from <10 to 176 micro g/L. In Bakechi township, mean height increased from 91 cm in 1993 to 106.5 cm in 1998 - 1999, HC from 48.7 to 49.6 cm, and median urine iodine from 39 to 138 micro g/L.</p><p><b>CONCLUSION</b>In Xinjiang, adequate iodine treatment markedly decreased infant and neonatal mortality, and largely preventing stunting of height and HC in children.</p>

ABSTRACT

Objective: To investigate the action of low level soybean isoflavones (genistin, genistein and daidzein) on the oxidative modification of lipoproteins in serum. Methods: After a system of lipoprotein oxidation mediated by Cu 2+ was established in a dilute serum, the effects of soybean isoflavones on the course and the end of lipoprotein oxidation could be reflected by monitoring the production of conjugated dienes and thiobarbituric acid-reactive substances (TBARS) respectively when isoflavones were added. Results: After 0.5-10 ?mol/L genistein, daidzein, genistin or ?-tocopherol was added into the lipoprotein system respectively before the oxidation initiated by Cu 2+ , the production of conjugated dienes or TBARS in the system was significantly reduced with a dose-dependent relationship. When the lipoprotein oxidation was initiated by Cu 2+ at 37 ℃ for 1 h or 1.5 h, soybean isoflavones also revealed strong inhibition on the oxidation in a weakening way. In comparison with soy isoflavones, ?-tocopherol had smaller inhibition on the production of conjugated dienes, but had promotion on the increase of TBARS. Conclusion: Lipoprotein oxidative modification in serum was weakened by low level soybean isoflavones, and its action after the oxidation initiated was more effective than that of ?-tocopherol.
