Objective To explore the immunophenotype of chronic lymphocytic leukemia (CLL). Methods The immunophenotypes of 31 patients with CLL were determined by immunocytometry. Results Among 31 cases with CLL, the positive expression rates of CD19,HLA-DR, CD5, CD23, CD20, CD22, CD38, FMC7 and CD10 were 100%, 96.8%, 90.3%,90.3%, 83.9%, 54.8%, 32.3%, 6.5% and 0.0%, respectively. Conclusions The imrnunophenotype analysis is very important for diagnosing CLL and it can early detect monoclonal B-cell lymphocytosis of CLL, which is the early phase of CLL, and provide early warning for patients.

BACKGROUND: Osteochondral lesion of the talus is a common disease of foot and ankle surgery, which has the characteristics of high morbidity, high misdiagnosis rate and difficulty in curing. OBJECTIVE: To summarize the etiology, clinical manifestations, diagnostic methods, clinical grading, treatment methods, and new therapies such as cell therapy and tissue engineering for osteochondral lesion of the talus.METHODS: The first author retrieved PubMed databases for relevant articles. The keywords were "talus, cartilage". Initially, 535 articles were retrieved, and finally 70 articles were included in result analysis. RESULTS AND CONCLUSION: Trauma is still considered to be the main pathogenic factor of talus cartilage injury. According to the imaging findings, the clinical scope of talar cartilage injury can be accurately determined. The clinically applied therapies have certain shortcomings and limitations. Tissue engineering-based therapies are currently the most likely to cure osteochondral lesion of the talus.
