Objective To investigate the treatment of inverted nipple by continual extension with S tractors made of Kirschner wires on the base of preliminary clinical obervation.Methods Under local anesthesia,with the inverted nipples being dragged out by a presutured thread or a pair of towel clips,a Kirschner wire of 10 cm long and 0.5-1.0 mm in diameter was transversly penetrated through the base of inverted nipple.Then the Kirschner wire was bended at both points of 1.5 cm distantly from the nipple center in clockwise cemicircularly.Two cemicircular Kirschner wires were folded downward hingelikely and the center axis was supported by two cemicircles.This folded S tractor pushed and supported the inverted nipple forwardly and constantly.The hinge angle was adjusted during the treatment according to the traction requirment.It was nessessary for wearing these S tractors for at least 6 months before the Kirschner wires were being taken out.During referrals,the hinge angle was revised for mentaining the extension efforts.Results We treated 32 cases of inverted nipple,total 58 moderate and severe lesions,with this method effectively.No infection was observed during the treatment.The nipple form was naturally and stably outstanding after Kirschner wires taken out.No relapses were observed during a mean 6 monthe following up.Conclusions This procedure is simple and convenient without the need of complicated surgical procedures or perplexed equipments.The nipple shaps are observed natural and stable after Kirschner wire is removed.No recurrences are observed.There are no damages to breastfeeding function.The obvious drawback of this method is its reqairing of long continuously wearing and its inconvenience.

Objective To investigate the association between serum ferritin(SF) level at early and mid trimester of pregnancy and gestational diabetes mellitus (GDM) and insulin resistance (IR).Methods A total of 192 cases of women who were accepted antenatal examination from the first trimester of pregnancy at Yueqing People Hospital from July,2012 to October,2013 was prospectively analyzed and followed up.All cases were divided into two groups:96 cases of GDM pregnant women who were diagnosed as GDM at mid trimester of pregnancy as GDM group,and 96 cases of pregnant women with normal glucose tolerance at the same time as the control,normal glucose tolerance (NGT group).The differences in clinical data were compared between two groups.The relationship between SF level and fasting plasma glucose (FPG),fasting insulin (FINS),homeostasis model assessment insulin resistance (HOMA-IR),and C-peptide was investigated with Spearman rank correlation analysis.The predictive values of SF and relative variables to GDM were calculated by receiver operating characteristic curve (ROC) or Logistic regression analysis.Results (1) There was statistically significant difference in body weight and body mass index (BMI) at prepregnancy and mid trimester of pregnancy,Hb,FPG,FINS,SF,and C-peptide at the first trimester of pregnancy,SF level and FPG and HOMA-IR and C-peptide at mid trimester of pregnancy between two groups (P ＜ 0.01 or P ＜ 0.05).(2) As showed by Spearman rank correlation analysis,there was statistical correlation between SF at mid trimester of pregnancy,and FPG,FINS,HOMA-IR and C-peptide (P ＜0.01 or P ＜ 0.05);while no statistical correlation was found between SF at the first trimester of pregnancy and the same factors above (P ＞ 0.05).(3) The area under the ROC curve of SF at mid trimester of pregnancy for GDM was 0.653.The sensitivity and specificity were 68.8％ and 59.4％ in predicting GDM at the cut-off value of 16.61 ng/ml.As showed by Logistic regression analysis,high level of SF at mid trimester of pregnancy was a independent risk factor for GDM.Odds ratio (OR) was 1.032 (95％ CI:1.008 ～ 1.058,P ＜ 0.01).Conclusions The relationship between SF at different trimester of pregnancy and GDM is variant.There is relationship between high level SF of mid trimester of pregnancy in GDM pregnant women and IR.The level of SF might predict the occurrence of GDM.

Objective To evaluate the cosmetic outcomes of nasal aesthetic sub-unit principle. Methods From May 2007 to March 2015,19 patients with traumatic soft tissue defects of nose had a Single-stage reconstruction with suitable reconstructive method. Full-thick-ness skin transplantation was performed in 1 case,forehead nasal flap in 1 case,bilobed flaps in 2 cases,nasolabial flaps in 9 cases,a folded nasolabial flap in 2 cases,free auricular composite flap in 1 case,the temporal flap pedicled with the orbicular oculi muscle in 3 cases. All pa-tients were followed up for 5~27 months,evaluation items were recorded and analyzed. Results Skin transplantation and local flap were all survived. But 1 case with nasolabial flap infected was healing by second intention,the rest were primary healing,free auricular composite flap was gloomy,and it became normal 5 months after operation. The radian and the curve of the folded nasolabial flap to repair the nasal alar area were slightly poor. Condusion Good aesthetic effets come from nasal aesthetic sub-unit principle in Single-stage soft tissue reconstruction of a traumatic nasal defects.
