Objective To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.Methods From July 2014 to July 2016,selected 12 patients (3-10 years old,mean 7.2 years old) with concealed penis were surgically treated with the modified Brisson technique in the Second Affiliated Hospital of Nanjing Medical University.Their clinical manifestations included the penis buried below the surface of prepubic skin which can be palpated and visualized through pushing the skin around the penis to the pubis and the short foreskin which was not attached to the penile corpus cavernosum.Patients with other conditions such as obesity and penial agenesis that caused buried penis were excluded from the study.The modified Brisson technique consisted of 4 steps.Ventral incision was used to gradually slit the narrow ring of the prepuce and to expose the glans followed by circumfe-rential inner foreskin incision made below the coronary sulcus of penis then the foreskin stripping released the corpus cavernosum.Finally the skin coverage was accomplished by posthioplasty.The operation time,blood loss,complications,postoperative treatments and followed-ups were retrospectively analyzed.Results For all the 12 patients,the operations were successful,lasting 40 to 60 minutes.The bleeding was about 5 to 10 mL and there was no operation-related complications like bleeding and infection of incision.Satisfactory cosmetic outcomes were obtained without retraction and the scars were similar to those of circumcision.All patients had penile lymphedema postoperatively which disappeared within 6 months after operation.Follow-up ranged from 6 months to 1 year,and there were no complications like skin necrosis and contracture or voiding difficulty.Conclusions The modified Brisson technique for concealed penis repair is technically easy and safe.In addition,it provides a good cosmetic appearance,functional outcomes and excellent postoperative satisfaction grades.

Objective To evaluate the clinical effect of ligation of the descending branch of uterine artery and compression sutures at the lower uterine segment in managing postpartum bleeding due to pernicious placenta previa. Methods Clinical data of 227 patients with pernicious placenta previa, admitted to Shenzhen Maternity and Child Healthcare Hospital between June 2010 and June 2013, were retrospectively analyzed. Eight-two women,who were admitted between June,2010 to December,2011, receiving B-Lynch sutures combined with uterine lower segment packing after delivering the baby and placenta during cesarean section were assigned as the control group. Another 145 cases, who were admitted between January 2012 to June 2013, receiving ligation of the descending branch of uterine artery and compression sutures at the lower uterine segment, were defined as the observational group. Several indicators during and after the operation were compared between the two groups. T-test or Chi-square test were applied for statistics. Results The duration of operation in the observational group was shorter than in the control [(92±26) vs (106±32) min, t=3.579, P<0.01]. The estimated blood loss during the operation, the total blood loss during the first 24 h after delivery and the blood loss during the operation for placenta percreta in the observational group were all lower than in the control [(1 230±481) vs (1 858±632) ml, (1 475±236) vs (2 482±364) ml, and (2 131±515) vs (2 587±498) ml, t=8.413, 25.295 and 6.484, all P<0.01]. The adjusted postoperative hemoglobin values of the observational group were significantly higher than that of control [(82±21) vs (69±19) g/L, t= - 4.634, P<0.01]. Besides, significant differences were found between the observational and control group on the rates of hysterectomy, blood transfusion, and uterine artery embolization [1%(2/145) vs 7%(6/82), 40%(58/145) vs 66%(54/82), 2%(3/145) vs 12%(10/82), χ2=5.408, 13.945 and 9.904, P < 0.05 or 0.01]. The dosage of Carboprost Tromethamine required was smaller in the observational group [(573±104) vs (729±128) μg, t=9.971, P<0.01]. Conclusions Ligation of descending branch of uterine artery and compression sutures in the lower uterine segment during cesarean section in women with pernicious placenta previa is an effective and simple method to control bleeding resulting reduction of blood loss and the hysterectomy rate.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.
