Objective To explore a new methodology with bilateral rhomboid dermal flaps for surgical treatment of inverted nipple. Methods 36 cases with 64 inverted nipples were involved in this study. Among these cases, 8 of them were evaluated as mild degree, while 19 moderate and 9 severe. In this procedure, the bilateral rhomboid incisions were designed. The rhomboid skin was deepithelialized and two dermal flaps were created. Then these two dermal flaps were filled crosswise through the tunnel beneath the nipple and fixed as supporting. After the operation, the continuous traction of the nipple lasted for one week, and sutured out 10 days later. Results None of these 36 cases appeared nipple blood circulation disorder after operation. Postoperative follow-up for 6 months-3 years showed that the appearance of the nipple was satisfactory. There were no recurrence and sensory disturbance. Conclusions The method introduced in this study is simple, the appearance of nipple is natural and no complication has been found. The incision is larvaceous while the scar is invisible. Meanwhile this method is also benefit for reserving the function of breast-feeding. It is proved to be an ideal method for correcting the inverted nipple.

BACKGROUND: Previously, more researches are about the pathological changesinskeleton, nerveandmuscularofcongenitalclubfoot(CCF). Researches are exploring the changes in the surrounding soft tissues of the deformed feet.OBJECTIVE: To investigate the relationships between the pathogeny,pathology and pathogenesis of CCF and extracellular matrix (ECM).DESIGN: A completely randomized controlled trial.SETTING: Institute of Orthopeadics of the Fourth Military Medical University.PARTICIPANTS: The study was conducted in the Institute of Orthopeadics of the Fourth Military Medical University from November 1997 to August 2003. The deep fascia of study group was obtained from 15 CCF patients who received operative corrections including 11 males and 4 females with an average of 9 months. Five infant corpses who died from non-neural muscular diseases and non-collagen diseases aged between 4 and 21 months with an average age of 11 months were selected in the control group.METHODS: Immunohistochemical investigation was used for the assay of both study and control group. Slices were quantitatively analyzed by Letica Q,570c color image analysis and management system.MAIN OUTCOME MEASURES: Positive expressions of collagen Ⅰ, Ⅱ and Ⅲ, and the relative contents in the deep fascia of both groups.RESULTS: The grey values for relative contents of collagen Ⅰ, Ⅱ and Ⅲ in the interior foot were 116. 43 ± 11. 80, 132. 91 ± 8. 88, and 184. 40 ± 11.82respectively in the study group, and 169.28 ± 8.17, 176. 33 ± 9.47, and 194. 38 ±5.87 in the control group. The contents of collagen Ⅰ, Ⅱ and Ⅲincreased in the contractured tissues of CCF group with the most significant increase in collagen Ⅰ, followed by collagen Ⅲ and the increase of collagen Ⅱwas least. Additionally, collagen Ⅰ was negatively correlated with collagen Ⅲ. The positive expression of collagen Ⅱ might be an accompanying phenomenon, which had no correlation with collagen Ⅰ and Ⅲ.CONCLUSION: ECM changes in CCF are accorded with fibrosis in tissues and organs and general fibroelastosis. Therefore, CCF might be caused by the fibrosis of interior foot.

Objectives To review the clinical features in children with methylmalonic academia (MMA) having the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment. Methods The clinical data of 4 children diagnosed of MMA with the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment were retrospectively analyzed from August 2013 to present. Results In the four children (two boys and two girls) with the age from nine months to three years seven mouths, two children were diagnosed with MMA combined with homocysteine, and 2 children were diagnosed with MMA, but there was no homocysteine testing. All four children showed moderate to severe anemia, proteinuria, hematuria, and hypertension. One child had abnormal renal function and thrombocytopenia, and manifested as hemolytic uremic syndrome. Renal biopsy was performed in 2 children and they had glomerular sclerosis lesions with renal tubular necrosis and mesangial proliferative glomerulonephritis respectively. All children were treated with vitamin B12, and the indexes of microangiopathic hemolytic anemia and renal impairment were improved signiifcantly. Conclusions MMA may be combined with microangiopathic hemolytic anemia, renal impairment and even hemolytic uremic syndrome, and the early diagnosis and treatment is required.

Objective To summarize the application experiences and curative efficacies of single lung transplantation assisted by extracorporeal circulation with coated lung ,centrifugal pump and coated pipe .Methods Retrospective analysis was conducted for clinical data of 6 adult patients with respiratory insufficiency undergoing single lung transplantation .The changes of hemodynamics and oxygenation before and after adjuvant treatment were observed ,the effects of adjuvant evaluated and the experiences of application summarized .Results The hemodynamic parameters post-assistance significantly improved as compared with that pre-assistance and pulmonary arterial pressure dropped from (56 ± 15 ) to (45 ± 13 ) mmHg with statistically significant differences . Arterial blood gas parameters significantly improved .PO2 spiked from (47 ± 12) to (68 ± 9) mmHg and PCO2 declined from (65 ± 14) to (55 ± 12)mmHg .And there were statistically significant differences .All patients were discharged successfully .Conclusions The simple extracorporeal membrane oxygenation system of coated lung , centrifugal pump and coated pipe during routine extracorporeal circulation may guarantee the operative safety of single lung transplantation and provide a new therapeutic option .
