1.Interleukin-2 and its receptor abnormalities in Ankylosing Spondylitis and Rheumatoid Arthritis
Chinese Journal of Immunology 1985;0(03):-
The production of IL-2 by peripheral blood lymphocytes from patients with Ankylosing Spondylitis (AS)and Rheumatoid Arthritis (RA) was compared with that of healthy controls. Patients with AS and RA showed a significant overproduction of IL-2.Membrane-bound IL-2 receptor was recognized by monoclonal anti-Tac antibody by using a flow cytometry. There was a marked increase of IL-2 receptor in patients with RA, while the level of IL-2 receptor in patients with AS was comparable to that of normal controls. The results suggested that there was obvious abnormalities of membrane-bound IL-2 receptor expressing and production of IL-2 in patients with AS and.RA which may contribute to the pathogenesis of these diseases.

Chinese Journal of Rheumatology 2001;5(2):113-116
Objective To better understand the clinical characters of juvenile onset spondyloarthropa-thies (JSpA).Methods The clinical and laboratory data of 190 in-patients with JSpA were analyzed and the diagnosis,classification and differentiation of juvenile onset arthritis were discussed.Results Among these 190 patients,163 were male,with a male to female ratio 6∶1.Of them 92.1% had the disease after the age of 8.Peak of age at onset was 12 to 15 years;157(82.6%) patients had peripheral arthritis and only 23(12.1%) patients felt low back pain at onset.During the disease course, peripheral arthritis was found in 187(98.4%) patients and the history of low back pain or buttock pain was recorded in 123(64.7%).The interval between peripheral arthritis and low back pain was from 0 to 20 years,with an average of (3.2±4.5)years.Extra-articular features including enthesitis in 67(35.3%)patients,dactylitis in 20(10.5%),iritis in 9(4.7%) were observed.HLA-B27 was positive in 87.9%(160/182) patients.Sacroiliitis on X-ray was observed in 76.0%(136/179) patients,and 106(55.8%) patients were diagnosed juvenile ankylosing spondylitis (JAS) according to 1984 New York modified criteria.The average disease course in JAS was (6.3±6.2) years,longer than that in JSpA (P<0.01).Conclusion The concept of JSpA is helpful to early diagnosis and treatment of juvenile onset arthritis.The JSpA are characterized by asymmetric lower limb predominant oligoarthritis,a wide spectrum of extra-articular features,presence of HLA-B27 and familial history of SpA or psoriasis.It will take an average of 6.3 years for JSpA patients to fulfill the diagnostic criteria of adult AS.
5.Detection and significance of urokinase-type plasminogen activator and its receptor in synovial fluid and plasma in rheumatoid arthritis
Chinese Journal of Rheumatology 2001;5(3):148-151
Objective To measure the levels of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) in synovial fluid and plasma of patients with RA and investigate its clinical significance.Methods By using ELISA sandwich method,the levels of uPA and uPAR in plasma from 46 patients with RA and 8 with osteoarthritis (OA) were measured.Those in synovial fluid (SF) from 14 patients with RA,and plasma from 12 healthy subjects were measured as controls.Results The concentration of uPA and uPAR in SF from patients was significant higher than that in their plasma (P<0.001,P<0.01),and the concentration of uPA and uPAR in plasma of RA was also much higher than that in plasma of OA patients (P<0.05,P<0.000 1) and healthy subjects (P<0.000 1,P<0.001).There was no significance between plasma levels of RF+ and RF- in RA patients.The concentration of uPA and uPAR of plasma in RA correlated positively with CRP,RF and the number of swelling joints.Conclusion The levels of uPA and uPAR in SF and plasma are useful parameters for monitoring disease activity of RA.These findings suggest that the uPA and uPAR genes may play an important role via proteolytic damage of the extracellular matrix during the development of RA.

9.Expression and regulation of Bim protein in chronic myelogenous leukemia
Journal of China Pharmaceutical University 2009;40(6):571-575
Aim: To investigate the expression and the regulation of Bim protein in leukemic cell of patient with chronic myelognous leukemia(CML). Methods: The primary leukemic cells from the peripheral blood or bone marrow of patients with CML were isolated and cultured. The expression of Bim in the present or absence of ima-tinib(BCR/ABL inhibitor) was detected by the Western blotting, immunohistochemical analysis and real-time quantitative PCR. Results: Bim was consecutively expressed in normal bone marrow, but significantly decreased in the bone marrow of patients with CML( P < 0. 05). Imatinib significantly enhanced Bim mRNA transcription and expression in the manner of time- and dose-dependence. Moreover, there was reverse correlation between Bim protein level and the percent of leukemic cell in bone marrow( r =0. 849 1, P <0. 05). Conclusion: Bim is the Bcl-2 family pro-apoptitic factor. The decreased expression of Bim could be vital in the CML, Bim protein up-expression following the suppression of BCR/ABL might be of importance in investigation of the Bim-induced ap-optosis for potential clinical therapy.
