Objective: Osteoarthritic lesions of Temporomandibular joint(TMJ) were assessed by dental cone beam computed tomography(CBCT),and compared with conventional radiographic technology. Methods: The study was conducted retrospectively on 511 joints of 350 patients, who had undergone dental CBCT ,panoramic radiography,transcranial projection and transpharygeal projection of TMJ . The results were compared and the accuracy with CBCT was assessed. The types of osseous condylar abnormalities were observed.Results: (1) The occurrence of osteoarthritis in male and female were 59.04% and 69.66%, respectively, with no significant difference. (2) Compared with CBCT, panoramic radiography,transpharygeal projection examination showed no significant difference, with the accuracy being 90.64% and 94.10%,respectively;However, transcranial projection indicated a significant difference in comparison with CBCT and the accuracy was 86.97%. (3) A higher occurrence of osteoarthritic lesions of the condyle was sclerosis (39.86%). Bony proliferation or osteophyte (28.18%) and ill-defined cortical bone (18.90%) were followed. Conclusion: Cone beam CT, which reproduces multiple images including axial, coronal and sagittal planes of the joint, provides a complete radiographic investigation of the bony components of the TMJ. It is one of the best choices of imaging diagnosis of TMJ osteoarthritis. Panoramic radiography and transpharygeal projection examination are also good choices for showing osseous condylar abnormalities in the clinic, but transcranial projection examination is inferior.

Objective:To compare the wear resistance between dentin and dental restoration material in vitro.Methods:The friction and wear behaviors of natural tooth dentin respectively against highly polished polymer ceramic,glass ceramic and zirconia were investigated in an artificial saliva test environment by UMT-2 friction and wear testing machine.Worn surface morphology was observed by scanning electron microscopy(SEM),roughness was measured by roughness instrument,the rigidity value was weighed by electronic balance.Results:The roughness of the 3 materials was similar to that of dentin(P ＞ 0.05),the rigidity of dentin was less than that of the 3 materials (P ＜ 0.05).After friction and wear test,the abrasion quantity of dentin respectively against the 3 materials was less than that of the materials (P ＜ 0.05).There was positive correlation between the wear loss and the hardness of the 3 materials and dentin(r =0.846).The mass loss of the dentin against Poly Ceramic after grinding abrasion was the closest among the 3 materials.Conclusion:Different materials have varying degrees abrasion against dentine.The Polymer Ceramic has closer abrasion performancez with dentin than the other 2 materials.

Objective To explore the value of Swansea criteria on diagnosis and severity evaluation of acute fatty liver of pregnancy (AFLP).Methods Fifty-two AFLP patients were admitted to Shandong Provincial Hospital Affiliated to Shandong University between January 1,2000 and December 31,2011.All these cases were retrospectively reassessed by Swansea criteria.According to the severity,prognosis and whether continuous blood purification treatment was needed,these cases were classified as mild and severe cases.Differences between groups were detected by x2 or t test.Bivariate correlation analysis was used for Swansea criteria compliance and postnatal hemorrhage and days in hospital.Results After reassessing by Swansea criteria,31 cases could be diagnosed as AFLP (20 cases met seven or more criteria,11 cases met six criteria)and the other 21 cases could not (16 cases met five criteria,three cases met four,and two cases met three).For the 16 cases that met five Swansea criteria,they were confirmed as AFLP based on postnatal follow-up.The five cases that met four or three criteria were confirmed as AFLP because no other disease could explain their status.Among the patients who met seven or more Swansea criteria,the incidence of intrauterine fetal death was 40％ (8/20),and 65％ (13/20) needed continuous blood purification.These were higher than in patients who met six or fewer Swansea criteria [9％ (3/32) and 28％ (9/32),x2=6.921 and 6.857,P=0.014 and 0.011].Postpartum hemorrhage was positively correlated with Swansea criteria compliance (r2=0.286,P=0.040).Conclusion Patients who meet five Swansea criteria can be diagnosed as AFLP.Swansea criteria can be applied to the severity evaluation of AFLP.

Objective To assess the value of fiberobronchoscopy in the diagnosis of endobronchial tuberculosis. Methods A total of 67 children suspected of endobronchial tuberculosis in our ward from March 2010 to December 2012 had been tested by chest CT and ifberobronchoscopy, mycobacteria culture, liquid-based interlayer vessel technique and FQ-PCR from bronchoalveolar lavage fluid and biopsy. Results 50 patients were clinically diagnosed as endobronchial tuberculosis. The positive rate of FQ-PCR (60%) and liquid-based interlayer vessel technique (42%) are higher than that of mycobacteria culture (20%), which showed no signiifcant difference with biopsy. The positive rate of the combined detection (FQ-PCR and liquid-based interlayer vessel technique) is significantly higher than that of mycobacteria culture and biopsy. Conclusions Fiberobronchoscopy is effective for the diagnosis of endobronchial tuberculosis.
