RESUMO
Objective@#To discuss the surgical method and clinical effect of applying the facial artery perforator-based nasolabial para-nasal advanced flap to repair the medial canthus and inner lower eyelid skin defects.@*Methods@#The advance nasolabial para-nasal perforator flap supplied by facial artery, was used to repair the medial canthus and inner lower eyelid skin defects, caused by dermatoma excision.@*Results@#All 18 flaps completely survived. The detects in the medial canthus andinner lower eyelid, and the donor sites in the nasolabial fold were primary healed.The medial canthus and inner lower eyelid were recovery satisfactorily.The flaps were not bloated, and the contour and texture of flaps were similar to adjacent tissue, with no need of secondary repair.The donor site was successfully hidden in the nasolabial dermatoglyph.@*Conclusions@#Nasolabial para-nasal perforator flap is easily obtained, reliable in blood supply, and flexible in transfer. It has a wide range of movement and is easy to advance, so as to repair medial canthus andinner lower eyelid defect. With above advantages, this flap is worthy towidely popularize.
RESUMO
A nutrition survey, covering a total of 4801 preschool children in 6 provinces, autonomous regions and municipalities, has been carried out. The objective was to determine the effects of various dietary patterns on the blood hemoglobin, free erythrocyte proporphyrin, and serum ferritin values. The results indicated a high prevalence of iron deficiency (average 51.9%). Iron deficiency anemia was detected in 16.4% of the children examined and the incidence rate was particularly high among infants at the age group of 6 months and one year, which was 28.7% and 22.9% respectively. The dietary patterns were different in the above geographic areas. The results of dietary survey revealed that a low incidence of iron deficiency was found in those children who consumed more animal food and protein.
