Objective To explore the effect of preservation of inclined fractured permanent molars by transverse fixation with screw post,and provide a practical method for reserving the inclined fractured permanent molars.Methods Clinical data of 50 patients with inclined fractured permanent molars by transverse fixation with screw post in the Department of Stomatology of Tianjin First Central Hospital between January 2010 to December 2011 were reviewed retrospectively.After fixing the crown with steel-wire binding and root canal treatment,the molars were drilled a hole buccolingually and placed screw post.The flowable light-curing composite resin was used to seal the crack and bond screw post to prevent the relative movement.All treated molars were restored with full crown.All patients were followed up for 10-60 months.The therapeutic effects were observed.Results After 5 year-follow-up,41 cases were cured completely,6 cases were cured clinically,and 3 cases failed treatment.Conclusion The transverse fixation with screw post and bonding technique can preserve the inclined fractured molars to gain chewing function and avoid or reduce the extraction of affected teeth,which provides a better restoration effect.

Objective To investigate the relationship between neurokinin B (NKB), endothelin-1 (ET-1) and the pathogenesis of hypertensive disorder complicating pregnancy (HDCP). Methods 22 HDCP, who received antenatal examination in the Department of Obstetrics and Gynecology of Union Hospital of Tongji Medical College in Huazhong University of Science and Technology from March to July in 2005, were selected for the study, including 12 gestational hypertension (gestational hypertension group) and 10 preeclampsia (preeclamptic group); 22 normal pregnant women in the same period were served as control. At different gestational weeks, maternal plasma levels of NKB and ET-1 in three groups were detected by enzyme-linked immunoassay technique, the expression and location of NKB in placenta were examined by immunohistochemical SP, and mRNA expressions of NKB and ET-1 in placenta were measured with RT-PCR method. Results (1) At 10 - 14, 20 - 24, and 30 - 34 gestational weeks, the plasma levels of NKB and ET-1 in preeclamptic group were ( 35. 6±5.2), ( 17. 9±4. 3), (39. 5±4. 3 ), (22. 7± 3.6), (47. 1±3. 3) and (27.5±3.5) μg/L, respectively; in the control group they were (22. 9±3. 3), (10.7±5.3), (30.2±3.4), (13.2±4.1), (34.6±4.3) and (16.6±4.8) μg/L, respectively. There was a significant difference between preeclamptic group and control group ( P < 0. 05), while there was no significant difference between gestational hypertension group and control group (P>0.05).(2) Immunohistochemical staining for NKB protein was observed in all groups and was located in the villous syncytintrophoblast and villous vascular endothelial cells as well as cytoplasm of stromal cells, mostly located in villous syncytiotrophoblast. The expressions of NKB in placenta of preeclamptic group (0.244±0.020) was significantly higher than that in control group (0. 160±0. 012), with a significant difference between the two groups (P<0.05 ). However, there was no significant difference between gestational hypertension group (0.162±0.019) and control group (P>0.05). (3) The transcription levels of the NKB mRNA (0. 97±0. 36) and ET-1 mRNA (0. 90±0. 36) in preeclamptic placentas were both significantly higher than those in control groups (0. 78±0. 54, 0. 65±0. 47, respectively ), with a significant difference between the two groups( P <0. 05 ). But there was no significant difference between gestational hypertension group (0. 80±0. 40, 0. 70±0. 32, respectively) and control group (P >0. 05). (4) There was an evident positive correlation between plasma NKB and ET-1 levels in preeclampsia ( r =0. 79, P < 0. 05 ). Conclusions The significantly increased maternal plasma levels of NKB and ET-1 of patients with preeclampsia occur at early pregnancy (10 -14 gestational weeks) before the onset of clinical symptoms. The change of maternal plasma levels of NKB and ET-1 is closely related to pathogenesis of HDCP.

BACKGROUNDMediastinoscopy has experienced a renaissance due to the introduction of neoadjuvant treatment protocols and recognition of the limitations of noninvasive mediastinal staging of lung cancer by CT and PET. The aim of this study is to determine the value of video-mediastinoscopy in mediastinal staging of lung cancer.

METHODSA total of 60 patients who underwent video-mediastinoscopy for known or suspected lung cancer were retrospectively reviewed. There were 52 cervical mediastinoscopies, 2 parasternal mediastinoscopies and 6 combined procedures. All the patients were found to have enlarged mediastinal lymph nodes on radiographic examination of the chest (more than 1.0cm on its shortest axis).

RESULTSOf the 60 patients, 42 patients were found with N2 or N3 disease on video-mediastinoscopy and then were confirmed pathologically. The other 18 mediastinoscopy-negative patients underwent thoracotomy for pulmonary resection and mediastinal lymph node dissection in the same operative session, in which thoracotomy-proven N0 was found in 17 patients, and N2 in 1 patient (false-negative result by video-mediastinoscopy). The sensitivity, specificity, and accuracy of video-mediastinoscopy for mediastinal staging of lung cancer were 97.7%, 100% and 98.3%, respectively. In the entire group of 60 patients, there was 1 complication (1.7%) , and no perioperative death.

CONCLUSIONSVideo-mediastinoscopy is a highly effective and safe procedure. It can be used routinely in mediastinal staging of lung cancer.
