Objective To study the application of Polypropylene-Prolene Hernia System ( PHS) in tension-free herniorrhaphy of femoral hernia. Methods A total of 36 patients with femoral hernia were randomly divided into 2 groups to receive respectively PHS or Plug repair procedure. Data collected included; operative time, hospital stay, postoperative complications and recurrence rate. Results In PHS and Plug groups, the operative time were (42?7) min and (41?4) min respectively, the hospital stay was (4. 1?1. 0) d and (4.4?1. 2) d respectively. During the follow up period from 6 to 30 months,there was no recurrence, one case of scrotal hydrocele in PHS group, and there were two cases of recurrence and one case of ecchymoma in Plug group. Five patients complained of foreign body feeling in Plug group, and no patient in PHS group ( P

OBJECTIVE:To investigate the effects and safety of erythropoietin on nerve function and brainstem auditory evoked potential in the preterm children with brain damage. METHODS:46 preterm children with brain damage were randomly di-vided into treatment group and control group,with 23 cases in each group. Control group received conventional symptomatic treat-ment as respiratory support,nutritional support,vitamin K supplement and ganglioside. Treatment group was additionally given rhE-PO for injection (CHO cell) 500 IU/kg hypodermically,3 times a week,on the basis of control group. Both group received 3-4 weeks of treatment continuously. MDI,PDI,the content of serum nerve injury factor(NSE,S-100β),latent period and peak inter-val of brainstem auditory evoked potential were compared between 2 groups before and after treatment,and the occurrence of ADR was observed in 2 groups. RESULTS:There was no statistical significance in MDI,PDI,the content of serum nerve injury mole-cule,latent period and peak interval of brainstem auditory evoked potential between 2 groups before treatment (P>0.05). After treatment,MDI and PDI of 2 groups increased significantly,while the content of serum nerve injury factor,latent period and peak interval of brainstem auditory evoked potential decreased significantly;the treatment group was better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Erythropoietin can significantly im-prove intelligence development,protect the damaged nerve cells and auditory nerve pathways with good safety.
