Objective To study the clinical features of penetrating renal trauma. Methods From March 1996 to November 2002,28 patients (male,mean age 31) with penetrating renal trauma were treated,the clinical data of these were studied and reviewed. Results Nonoperative treatment was carried out in 6 patients of grade Ⅱ injuries were reconstructed and the other 2 patients were managed by embolization with an excellent renal salvage rate.In 12 patients with grade Ⅳ injuries,6 underwent embolization successfully,2 were successfully managed reconstruction,4 required nephrectomy.3 patients were of grade Ⅳ injuries,2 of whom underwent nephrectomy and 1 was died. Conclusions The condition of vascular injury should be considered in treatment of penetrating renal trauma.Emblization is a ideal treatment for the grade Ⅲ-Ⅳ penetrating renal trauma.

Objective To study the histopathological features of injured urethra managed by urethral realignment or suprapublic cystotomy and to sum up the experience on its treatment. Methods Urethral realignment or suprapublic cystotomy were carried out for 20 dogs as the instant management;tissue specimens from the two groups were studied using hematoxylin and eosin stain,immunohistochemistry and electron microscopy and the result has been studied. Results Regeneration of urethra was demonstrated in the urethral realignment group at 8 weeks after urethral injured whereas regeneration has been in the suprapublic cystotomy group.The average length of urethral emphraxis was 3.8 cm in the suprapublic cystotomy group whereas that of urethral stricture only 2.5cm in the urethral realignment group at 32 week. Conclusions Urethral realignment might be the treatment of choice for the instant managerment of urethral disruption as compared with suprapublic cystotomy.

Objective To evaluate the application of urine diversion in prostatectomy for hemostasis. Methods In 86 cases underwent suprapubic prostatectomy urine diversion was carried out.The prostatic bed was compressed by the inflated baloon of the urethral catheter.The operation time was recorded and the amount of blood loss both during and after the operation were measured.Postoperative blood hemoglobin and urodynamic parameters were compared with those before operation. Results The average operation time for the 86 patients was 45 min.The average blood loss during the operation was 140 ml and the average postoperative drainage 190 ml.Blood transfusion is not needed in all.The ureteral catheters for urine diversion were maintained for an average of 7.2 days and the urethral catheter for 8.6 days.Normal micturation was noted right after the removal of urethral catheter in all the 86 patients.Postoperative blood routine and biochemical assays were not significantly different from those before operation.The average maximum urine flow rate was 21.5ml/s.2 of the patients have experienced difficulty in micturation.Normal micturation was resumed on endoscopic urethrotostomy.No secondary bleeding or upper urinary tract infection has been noted. Conclusions The application of urine diversion is an effective means of hemostasis in prostatectomy.

Primitive neuroectodermal tumor (PNET) is a small round cell malignancies, normally confined to the chest wall and soft tissues of children and young adults, and reports of this tumor existing in nasal cavity are scarce. We herein present a case of nasal PNET. A 35-year-old male patient presented with a chief complaint of stuffy nose was diagnosed with a primary nasal pPNET by the clinical, microscopic, immunohistochemical features. Since these tumors are highly aggressive and patient prognosis is typically very poor, early diagnosis, immediate surgical resection and re-resection if possible, early radiotherapy and chemotherapy and close follow-up are required. We also review literatures on pPNET.

OBJECTIVETo investigate the functions of human periodontal myofibroblast (MFB) in vitro.

METHODSHuman periodontal fibroblast (hPDLFs) was cultured and induced to MFB by transforming growth factor-β1 (TGF-β1). MFB was denoted as the experimental group, whereas the hPDLFs was the control group. The groups were continuously cultured and harvested at 0, 12, 24, 48, and 72 h. The MFB marker α-smooth muscle actin (α-SMA) was examined by immunocytochemistry. The expression of fibronectin (FN) between MFB was examined by immunocytochemistry to detect the MFB contact relationship. The mRNA expression levels of α-SMA, collagen (Col) I, and Col III were measured by reverse transcription-polymerase chain reaction (RT-PCT) to analyze extracellular matrix secretion. The protein expression levels of α-SMA and Col I were also assessed by Western blot.

RESULTSThe experimental group had significantly higher α-SMA expression than the control group at 0 h (P < 0.001). A positive expression of FN was found between MFB. The experimental group had significantly higher expression levels of Col I and Col III than the control group at 24 h (P < 0.001).

CONCLUSIONHuman periodontal MFB presents a continuous, high expression of α-SMA. MFB could interact through FN. MFB is significantly capable of extracellular matrix secretion.
