Methods Using Foley catheter ballon as a pulling and fixing device in Badenoch pull through procedure to treat 23 cases of posterior urethral stricture. Results Success has been achieved in 21 cases with good voiding during 6～12 months of follow up.2 cases failed,in one of which the segment of stricture being too long and the postoperative tension on urethra too great.18 cases under went urodynamic test after operation,Qmax being 19 ml/s(15～23 ml/s). Conclusions The use of a Foley catheter for traction in Badenoch pull through operation is simple,effective,nontraumatic and with less occurrence of complication.

Objective To explore the molecular mechanism of hypophrenia induced by Down syndrome (DS).Methods Ts65Dn mice were used as DS animal model.Three female mice and three male mice of three to twelve weeks old were mated.Among the 17 first-generation mice alive,five mice remained Ts65Dn trisomy and 12 mice were normal.Five Ts65Dn mice and five normal mice were selected randomly as Ts65Dn group and control group,and bred till 16 to 18 weeks old for experiments.Differential proteins in hippocampus of mice were tested by isobaric tags for relative and absolute quantitation (iTRAQ).Expressions of the differential proteins in Ts65Dn group were detected compared with those in control group.Results A total of 2805 proteins were identified in hippocampus of Ts65Dn group and control group,and significant differences were observed in the expressions of 374 proteins.Compared with those in control group,expressions of 195 proteins increased and 179 reduced in Ts65Dn group.Sorted by P value from low to high,the seven proteins with the lowest P value were uncharacterized protein C2orf47 homolog,isoform 2 of filamin A-interacting protein 1-like,zinc finger protein,isoform 1 of pericentriolar material 1 protein,SEC23 interacting protein,BAG family molecular chaperone regulator 3 and serpin H1.Conclusions Differential proteins are observed in hippocampus of Ts65Dn mice,perhaps closely correlating to neurological defects.The new technology of iTRAQ helps to screen and identify differential proteins in hippocampus.

Objective: To study the immunologic protection of selenium on gastric mucosal lesions of BALB/C mice infected by Helicobacter pylori (HP). Method:The model was built by ig HP in BALB/C mice and then effects of selenium on gastric mucosal lesions and the CD4、CD8 cells were observed.HP was examined by both of bacterial culture and rapid usease test (RUT). Results:1.0 ?g/g bw selenium could effectively prevent gastric mucosal damages induced by HP. HP could decreased the ratio of CD4 to CD8,but selenium could enhance the activity of CD4 cell and increase the ratio. Conclusion: Se can effectively prevent the gastric mucosal damages of mice infected by HP. One of the mechanisms is that Se can enhance the CD4 activity and increase CD4 /CD8.

Objective To provide valuable references for ultrasonic diagnosis of pelvic organ prolapsed (POP) by finding an eas ily detecting referential line based on MRI.Methods Data of 107 patients who underwent pelvic MRI were retrospectively analyzed.All the patients were divided into 6 groups according to age:Group 1 (20 29 years old),group 2 (30-39 years old),group 3 (40-49 years old),group 4 (50-59 years old),group 5 (60-69 years old) and group 6 (≥70 years old group).Four reference lines were set basing on the median sagittal view of T2WI:PS-PS line (the line connecting the two endpoint of the pubic symphysis),PIAS line (the line connecting the inferior margin of pubic symphysis and the bottom of sphincter internal anal sphincter),PPC line (the line connecting of the inferior margin of pubic symphysis and the point of the pubococcygeous attached on the rectum) and PM line (the line connecting of the inferior margin of pubic symphysis and the M point [the midpoint of the line from the crosspoint of PPC line and the front wall of the rectum mucosa to the bottom of sphincter internal anal sphincter]).The angles between the horizontal line and PS-PS line,PIAS line,PM line,PPC line (angle 1,angle 2,angle 3,angle 4) were measured,respectively.The differences of the angle among various age-groups were compared.The consistency between the two observes were evaluated.Results PM line was the closest line to the horizontal line.There was no statistical differences of angle 1,angle 2 and angle 3 among the 6 groups (all P＞0.05).The difference of angle 4 among the 6 groups were significant (F=3.42,P=0.01).Intergroup pairwise comparisons showed that significant differences were found between group 1 and group 4,group 5,group 6,between group 2 and group 4,group 5,group 6,between group 3 and group 4,group 5,group 6,respectively (all P＜0.05).And no significant difference was found in the other comparisons.The consistency of the two observers in meaning angle 1,angle 3 and angle 4 were good,but the consistency of angle 2 was poor.Conclusion Of all the referential lines,PM is the closest to the horizontal line and is less influenced by the patient's age.However,the feasibility of using PM lines as the ultrasound referential line is still unclear.

There are many factors which affect the effects of acetabular fracture treatment. According to the literature, they can be concluded as follows: First,factors before the injury, such as quality of bone, age, other diseases of the patient and the expectation of the patient for functional recovery; Secondly, injury related factors, such as type of fracture, presence or absence of complicated nerve injury, dislocation of the femoral head, soft tissue damage and other complications, and the degree of cartilage damage of the femoral head; Thirdly, operational factors, such as the time gap between trauma and surgery, accuracy of reduction, stability of the coxa after the operation, experience of the surgeon, selection of operative approach, conditions of the hospital and operative complications.

Objective To evaluate the repair of the immense abdominal wall defect after resection of malignant tumours occurred primarily in the abdominal wall or that invaded the abdominal wall secondarily. Methods Among the 20 eases, 12 eases were of malignant tumours within abdominal wall (9 eases of rhabdomyosareoma, 3 eases of malignant fibrous histocytoma), 8 eases with the invasion of abdominal wall from malignant turnouts were of retroperitoneal or intraabdominal malignant tumors (3 eases with retroperitoneal malignant tumours, 1 ease of transverse eolon carcinoma, 3 eases with local reeurrenee in abdominal wall of ascending colon carcinoma undergoing fight hemieoleetomy 2～3 years ago, 1 ease with abdominal wall implantation metastasis of renal carcinoma after resection 5 years ago ). Abdominal wall defects left over by resection were repaired with polypropylene and expanded polytetrafluoroethylene (PPePTFE) mesh. The postoperative eomplieation and healing rate were observed. Results Wounds healed by primary intension, with no subeutaneous hydrops, no incision infeetion, dehiscence and hernia, no intestinal adhesion in all eases. The rate of successful repairing for the abdominal defect was 100%. All patients were followed up, the meshes with no rejection, inflammation and incision hernia, no reeurrenee of tumour in the repaired abdominal wall. Conclusion The PP-ePTFE mesh is a favourable repairing material for the abdominal defect after tumour resection, with the advantages of strong tensility, good bioeompatibility.
