Objective To investigate the clinical value of MRI in treatment choice of anterior disc displacement with reduction. Methods 1.5 T superconducting MR was used to scan bilateral temporomandibular joints in 72 consecutive patients who were diagnosed by MRI as unilateral(66 patients)/bilateral(6 patients) anterior disc displacement with reduction at closed and open mouth. MRI sequences included oblique sagittal T2 weighted image and proton density weighted image, and 78 joints' images were acquired. According to the severity of clinical symptoms, all joints were divided into severe symptom group (45 joints) and mild symptom group (33 joints). Treatment was performed in severe symptom group , while follow up was conducted in mild symptom group. Disk position(angle between posterior margin of the disc and the condyle vertical line), disk morphology(biconcave, biplanar, biconvex, rounded, folded, thick posterior band), and joint effusion (none effusion, mild effusion, moderate effusion, marked effusion) were evaluated by two radiologists. The observer agreement for image evaluation was calculated using Kappa statistics. Group difference in disk position was compared using t-test and Chi-square test was used to compare group difference in disk morphology and joint effusion. Results The Kappa value between two radiologists were 0.816 and 0.832 (P<0.01) on evaluation of disk morphology and joint effusion. Statistical results indicated that the angles between posterior margin of the disc and the condyle vertical line in severe symptom group (54.2 ± 10.9)° were larger than those in mild symptom group (46.4 ± 9.0)° (t=3.37, P<0.05). There was no significant difference in disc deformation incidence between the two groups (χ2=1.18,P=0.277). The common deformation in sever symptom group was thick posterior band (χ2=5.65, P<0.05), and in mild symptom group was biplanar (χ2=5.67, P<0.05). No statistical difference in joint effusion incidence was observed(χ2=1.02,P=0.312). Moderate and marked effusion were more common in sever symptom group than that in mild symptom group (χ2=6.55,P<0.05). Conclusions MRI is a useful tool for making treatment choice in anterior disc displacement with reduction. Treatment should be given when the following occurred on MRI:moderate anterior disc displacement, disc deformation (excepting for biplanar), moderate or marked joint effusion.

Background and purpose:In order to look for the new biomarker with higher specificity and sensitivity, we investigated the relationship between expression of MGB-2 and chemotherapy response, and tried to find out whether MGB-2 may sever as a prognostic factor for the patients with ovarian carcinoma. Methods:The expression of MGB-2 was detected by flow-cytometry technology in ovarian carcinoma tissue. We analyzed the correlations among MGB-2 expression and clinical pathological factors, therapeutic effect and prognosis of the patients with ovarian carcinoma.Results:Positive detection of MGB-2 was 78%.(66/885). For the patients whose serum CA125 level did not drop to normal level after two courses of chemotherapy, the MGB-2 positive rate was significantly higher than in those whose serum CA125 level decreased markedly ( 85% vs. 62%, P=0.018). The positive rate was also higher in patients with recurrent disease than in those without recurrence (83% vs. 67%, P=0.097). In univariate survival analysis, the expression of MGB-2 was significantly associated with median survival time (P=0.021).Conclusions:MGB-2 expression is correlated with chemotherapy response and poor prognostic for the patients with ovarian carcinoma.

Objective The aim of this study was to investigate the clinical value of human serum Kallikrein 6 for the diagnosis and monitor of pithelial ovarian cancer. Methods Serum levels of KLK6 were analyzed with ELISA in 30 cases of epithelial ovarian carcinoma, 20 cases of benign ovarian tumor and 30 cases of healthy women. In the meantime, serum CAi25 was determined with chemiluminescence. Furthermore, serum levels of KLK6 and CA125 were also detected in 12 case of epithelial ovarian carcinoma with the same methods one week and the 3rd month postoperation of follow-up. Results Serum levels of KLK6 in epithelial ovarian carcinoma was higher than that in benign ovarian tumor and healthy women (P < 0.05). KLK6 also showed positive correlation with clinical stage, cytological grade, pelvic lymph node metastasis, recurrent or dead disease (P < 0. 05). On the contrary, KLK6 showed no significant correlation with pathological types (P >0. 05). After surgery of follow-up, KLK6 and CA125 were significantly decreased in 12 case of epithelial ovarian carcinoma (P < 0. 05). Furthermore, the total sensitivity and specificity of KLK6 in the diagnosis of epithelial ovarian carcinoma was 73.3% and 85.0% respectively, followed by the sensitivity to be 50. 0% and 88. 9% for the diagnosis of stage Ⅰ-Ⅱand Ⅲ-Ⅳ disease. Conclusion Our resuits showed KLK6 may be one of the reliable indexes for the diagnosis and monitor of ovarian cancer.
