Objective To explore the replantation method of upper limb's biplane mutilation in conjunction with soft tissue defect.Methods From January 2003 to January 2013,29 patients with upper limb's biplane mutilation in conjunction with soft tissue defect were treated.There were 21 males and 8 females with the average age of 28.6 years.The youngest one was 1 year old and the oldest one was 70 years old.All the cases underwent different replantation order and transplantation by using vascular and nerve and flap according to the lesion they suffered,including the defected plane and soft tissue.Results All replantation limbs were survived besides 2 cases with infection and 3 cases of delaying healed due to the part of tissue necrosis.Among all 29 cases,9 cases got excellent recovery,14 cases were in good condition,4 cases were poor and 2 cases were bad.The totally excellent and good rate of upper limb function was 79.3％ according to the limb reattachment function evaluation criteria of Hand Surgery of the Chinese Medical Association.Conclusion It can obtain higher survival rate due to our different replantations and method of tissue replantation to cure double plane mutilation in conjunction with soft tissue defect of upper limb.

Objective To explore the efficacy and safety of low-dose heparin in the treament of children with primary nephrotic syndrome (PNS). Methods It was an open and comparative trial. Eightyeight children with PNS in the hypercoagulable state,on the basis of administrating with glucocorticosteroid,were administrated with low-dose heparin that infused by micro pump oriented to time ( group A). Eighty patients only treated with glucocorticosteroid were chosen as control (group B). Results Serum-albumin and activated partial thromboplastin time (APTT) increased,but fibrinogen (Fib) decreased after therapy in the group A,and they all showed significant differences (P ＜ 0. 01 ). Serum-albumin increased after therapy in the group B and there was significant difference (P＜0. 01 ). However,APTT and Fib in the group B showed no significant difference( P ＞ 0. 05 ) between post-treatment and pretherapy. Post-treatment serum-albumin and APTT in the group A were significantly higher than those in group B, and Fib was significantly lower than that in group B ( P ＜ 0. 01 ). The rate of urine protein remission in group A (82/88) was significantly higher than that in group B (63/80). Urine protein remission time and edema disappearance time were significantly shorter in group A than group B ( P ＜ 0. 01 ). APTT of group A at the peak concentration of heparin after therapy was significantly higher than that of pretherapy ( P ＜ 0. 01 ), and the ratio was 2. 38. However, there was no significant difference in APTT at the valley concentration of heparin between post-treatment and pretherapy ( P ＞ 0.05 ). Conclusion Low dose-heparin infused by micro pump oriented to time in the treatment of children with PNS has an obvious anticoagulative effect. It can improve the rate of urine protein remission and shorten edema disappearance time. Meanwhile it is safety ,requires no laboratory monitor and has few drug side effects,thus it deserves further clinical application.

Objective To explore the efficacy and safety of low dose dopamine combined with phentolamine in the treatment of primary nephrotic syndrome (PNS) with edema. Methods Retrospective control studies were performed in 155 patients of PNS with edema, who received comprehensive treatment with small dose dopamine combined with phentolamine (group A). Patients treated with furosemide infusion were recruited as control (group B). Results The urinary output, urinary sodium increased after therapy in group A, showing significant differences (P ＜ 0. 01). But urinary potassium excretion, serum sodium and potassium showed no significant difference after therapy in group A. The urinary output, urinary sodium and potassium excretion increased and the serum sodium and potassium decreased after therapy in group B, all showing significant differences between before and after treatment (P ＜0. 01). The edema relief rate,urinary output, urinary sodium excretion, serum sodium and potassium in group A was significantly higher whereas urinary potassium excretion were significantly lower than those of group B(P ＜0. 01). The rate of drug adverse reaction in group A was significantly lower than that of group B. Conclusion Low dose dopamine combined with phentolamine in PNS with edema is safe and effective,which may be a substitute of diuretic like furosemide in the treatment of edema of patients with different blood volume.
