METHODS In the study, 114 SLE patients who complained of arthralgia or arthritis from May 2014 to August 2017 and 15 Rhupus syndrome patients were recruited for ultrasound evaluation. Ultrasound scans of the symptomatic joint areas were completed. The correlation between ultrasonographic changes and clinical characteristics was analyzed. Additionally, ultrasound changes of bilateral wrists and hands of the SLE patients were compared with those of the Rhupus syndrome patients. RESULTS In a total of the 114 SLE patients with 1 866 joints scanned, synovial hyperplasia, tenosynovitis, erosion, and osteophytes were all observed. Synovial hyperplasia was more often obia and erosion were more common in the Rhupus syndrome patients (73.3% vs. 36.2%, P=0.08; 66.7% vs. 14.5%, P=0.03) with significantly higher grey scale scores (7.4±6.4 vs. 1.6±4.1, P=0.04) than in the SLE patients. CONCLUSION Variety of changes could be observed by ultrasound in different joint areas of SLE patients. The ultrasonographic changes and clinical manifestations did not always correspond to each other. selleck Synovial hyperplasia and erosion was more common in Rhupus syndrome patients.OBJECTIVE To explore the prognosis factors that influence the postoperative survival rate in patients with malignant solitary pulmonary nodules and to provide a reference for the prognosis risk stratification of early lung cancer patients. METHODS In this study, we retrospectively reviewed 172 patients who were admitted to Peking University First Hospital from April 2006 to December 2013. All cases were radiologically defined as solitary pulmonary nodule and were pathologically confirmed to be stage Ia non-small cell lung cancer after surgical procedure. The patients' clinical and follow-up data were summarized and analyzed. The relevance between survival time and factors that may affect patients' prognosis was evaluated, which included gender, age, clinical symptoms, smoking history, comorbidity index, tumor biomarkers, nodule type, type of surgery, nodule location, nodule histopathological type, nodule size, histopathological differentiation grade, proliferating cell nuclear antigen Ki-67 expression level a007-1.035). CONCLUSION For patients with malignant solitary pulmonary nodules, with pathological defined as stage Ia non-small cell lung cancer, age, gender and Ki-67 expression levels might be important prognostic factors. Comprehensive consideration of Ki-67 proliferation index and clinical pathological features may help to stratify the prognosis more accurately and guide the selection of appropriate therapeutic strategies, which needs to be verified by multi-center studies.OBJECTIVE To evaluate the effects of cardiopulmonary fitness on arteriosclerotic cardiovascular disease (ASCVD) events in patients with different risks of ASCVD. METHODS This study enrolled 544 non ASCVD patients who underwent cardiopulmonary exercise testing in Peking University Third Hospital from September 2016 to April 2018. ASCVD overall risk assessment was conducted according to "Chinese Guidelines for the Prevention and Treatment of Adult Dyslipidemia". Peak oxygen uptake (VO2peak), the classic indicator of cardiopulmonary fitness, was accurately determined by cardiopulmonary exercise testing in all the patients. All of the patients were followed up clinically. RESULTS In the study, 506 patients completed the follow-up (250 lowrisk patients, 93 moderaterisk patients and 163 highrisk patients). The median follow-up period was 19 months (9-28 months), and 51 patients developed ASCVD events during the follow-up period, of whom, 33 cases developed myocardial infarction, unstable angina or coronary revasSCVD respectively. In the patients with highrisk of ASCVD, the results suggested that the incidence of ASCVD events was significantly decreased in the patients with moderate VO2 peak [OR 0.210 (95%CI 0.054-0.814), P=0.024] and high VO2 peak [OR 0.146 (95%CI0.025-0.870), P=0.035], but no significant effect of VO2 peak elevation on the incidence of ASCVD events was found in the low/moderate-risk ASCVD patients. CONCLUSION High cardiopulmonary fitness can significantly reduce the occurrence of ASCVD events in patients with high-risk of ASCVD.OBJECTIVE To analyze the distribution and area of occlusal contacts of clinical dental model using three kinds of digital analysis methods, to compare the results of these methods and traditional occlusal analysis method, and to further analyze the characteristics of each digital analysis method. METHODS A set of plaster models of normal subjects was selected. The models were scanned by lab scanner 3shape E4 and the files were exported in a stereolithography file format. In 3D analysis software Geomagic Studio 2013 and Geomagic Qualify 2013, the corresponding results of 3D occlusal contact distribution and occlusal contact area were obtained through three digital analysis methods "3D color difference map method", "point cloud analysis method", and "virtual articulating paper method". The occlusal contact distribution and occlusal contact area were also obtained by two traditional occlusal analysis methods "silicone interocclusal recording material method" and "scanned articulating paper mark method". A threshea of dental model. The results obtained by these methods can serve as references for the digital occlusal surface design of dental prosthesis and clinical occlusal analysis.OBJECTIVE To evaluate the three-dimensional (3D) reconstruction accuracy of the intercuspal occlusion (ICO) of the dental casts, by the dental articulator position method, and provide a reference for clinical application. METHODS The standard dental casts in ICO were mounted on average values articulator, and five pairs of milling resin cylinders were respectively attached to the base of both the casts. 100 μm articulating paper and occlusal record silicone rubber were used to detect the occlusal contact number between the posterior teeth of casts mounted on articulator in ICO. The occlusal contact numbers NA detected by the two methods were calculated simultaneously, as the reference. After the upper and lower casts were scanned separately, and the buccal data of casts in ICO were scanned with the aid of the dental articulator position, registration was carried out utilizing the registration software. Then the digital casts mounted in ICO as well as the buccal occlusal data were saved in standard tessellation language (STL) format.
