ABSTRACT
Objective To formulate the evaluation criteria for micro-appraisal of comprehensive talents and macro-evaluation of projects.Methods A total of 425 articles were included in the meta-analysis of literature review;Delphi's panel that involved 20 experts,2 rounds of questionnaire surveys were conducted to construct indicators for comprehensive evaluation of talent construction projects;AHP was used to calculate the index weight coefficients for each category of indicators.Results The talent construction project evaluation system includes two sub-systems:micro-evaluation of talents and macro-evaluation of projects.Among them,the talent micro-evaluation system,which includes 12 evaluation indicators,carries out assessments in terms of basic qualities,academic accomplishments,and research achievements.the macro-evaluation system of the project,include a total of 15 evaluation indicators,is mainly assessed from the macro level of project operations-project structure,project process,project results.Conclusions From the perspective of the combination of micro (human resources) and macro (projects),to build a universal index for comprehensive evaluation of talent construction projects,both for the evaluation of the project,but also to conduct a comprehensive evaluation of the training object.
ABSTRACT
Objective To determine the characteristics of paresteal lipomas with hypemstosis (esteochondromas or osseous protuberances)on CT images and to improve the knowledge of diagnosis and differential diagnosis of the disease.Methods CT images and clinical history of 6 patients with pathologically confirmed parosteal lipemas with hyperostosis were retrospectively reviewed.All of the 6 patients underwent plain CT scans.Results CT images clearly show lipomas and osseous projections or osteochondroma in the 6 cases.Parosteal lipomas were found with osteochondronms in 2 cages(1 at the isehium.and the other 1 at the femoral trochanter)and willl osseous protuberances in 4 cases(2 at the diaphysis offemurs.1 at the diaphysis oftibia and the other 1 at the sternum).These osteochondromas and ossous protuberances were surrounded by the adipose component of the neoplasm and had a firm attachment oftlle neoplasm to the underlying bone.The size ofthe osseous projections varied from 0.3 cm x1.2 cm to 6.0 cm x 4.0 cm.The shape of the osgeous projections was various.Osteochondromas found in 2 cases showed cortical continuity with the adjacent bone together with marrow continuity with tlle adjacent bone marrow.In the 4 cages of parosteal lipama with osseous protuberances,2 to 4 osseous protuberances were found in 2 case8 and solitary osseous protuberance were found in the other 2 cases.The lipomatoas companent showed typical features of adipose tissue on all images.The size of the lipomas varied from 3.0 cm ×2.0 cm to 11.0 cm×10.0 cm with clear border.Fibrous septa of different thickness were found within the adipose tissue.There was essification and (or) calcification in 1 case and muscle atrophy in 2 espies.Conclusions CT scan is useful in the presurgical evaluation of parosteal lipomas witll osteochondromas or osseous protuberances became it can demonstrates the morphology,location and extent of the lesions.and it can show their relationship to the surrounding structures. It is important for differential diagnosis and preoperative assessment of the lesion.
ABSTRACT
Objective To explore the clinical and MRI features of spontaneous osteonecrosis of the knee(SONK).Methods 15 patients with SONK diagnosed by clinic and imaging were collected.All of cases were examined by MRI,of them 5 cases underwent CT scan and 3 cases underwent radiographic examinations.Results The subchondral lesions were seen in all cases on MRI and the lesions located in the femoral condyle weight-bearing zone in 14 cases.The subchondral "fracture cleft"sign was found in 2 cases;the subchondral long T1 and short T2 linear abnormal signal intensity surrounding with bone marrow edema were shown by MRI in 3 cases of them.The subchondral focal lesions were slight long T1 and long T2 signal intensity in 10 cases.The subchondral lesion were showed clearly only in 2 cases of 5 cases with CT scan,and only 1 case of 3 cases with plain X-ray examinations.Conclusion MRI is more sensitive than CT and radiography in showing the lesions of SONK.The SONK can be diagnosed based on the clinical and MRI features.
