Objective To investigate the expression of phosphorylation-mammalian target of rapamycin (p-mTOR) in endometrial carcinoma. Methods The expressions of p-mTOR protein in tissues from 45 cases of endometrial adenocarcinoma, 7 endometrial atypical hyperplasia, and 6 normal endometrium were detected by immunohistochemistry SP method. Results The expression of p-mTOR protein maily restricted to cytoplasm. Compared with normal endometrium, the expression of p-mTOR protein in the cases of endometrial atypical hyperplasia and endometrial adenocarcinoma was significantly up-regulation(2.36 ± 0.76vs 6.21 ± 1.19, 15.82 ± 2.64)( F = 11.37, P ＜ 0.05 ). There was significant difference of p-mTOR protein in different histology class in endometrial adenocarcinoma (F = 8.27, P ＜ 0.05), but there was no significant difference of p-mTOR protein in different pathological grade in endometrial adenocarcinoma (P ＞0.05).Conclusion The expression of p-mTOR protein may participate in the occurrence and development of endometrial carcinoma.

OBJECTIVETo explore the effectiveness of absorbable hemostatic fluid gelatin in preventing postoperative cerebrospinal fluid leakage.

METHODSThe clinical data of 17 patients with dura mater tear were retrospectively analyzed from March to September in 2003. There were 16 males and 1 female, aged from 16 to 67 years old with an average of (39.6 ± 15.4) years. The injury site was at cervical vertebrae in 1 case, thoracic vertebrae in 9 cases, thoracolumbar junction in 4 cases, lumbar vertebrae in 3 cases. There were burst fracture in 4 cases and fracture-dislocation in 13 cases. According to ASIA grade, 12 cases were grade A, 2 cases were grade B, 2 cases were grade D, 1 case were grade E. Two cases caused by traffic accident, 10 by high falling, 4 by heavy parts crash, 1 by stairs fell during the earthquake. Absorbable hemostatic fluid gelatins were used to plug the dura mater tear,in order to prevent postoperative cerebrospinal fluid leakage. Postoperative drainage were recorded every day.

RESULTSOf 17 patients, 15 cases did not develop with cerebrospinal fluid leakage. Two cases develop with cerebrospinal fluid leakage after operation and their drainage were removed at 6 to 7 days after operation. In all cases, no complications related with cerebrospinal fluid leakage occurred, such as headache, dizzy, fever,neck resistance, rash, incision disunion, incision infection, hematoma, neurologic symptoms aggravation. No abnormal phenomena was found on incision surrounding at follow-up of 9 months.

CONCLUSIONUsing absorbable hemostatic fluid gelatin to plug the dura mater tear during operation is an effective method in preventing postoperative cerebrospinal fluid leakage.
