ABSTRACT

Objective:To explore the clinical teaching effect of case-based learning combined with diagnosis and treatment guidelines in standardized residency training in the department of rheumatology and immunology.Methods:Forty standardized trainees were randomized into two groups. One was the observation group, which adopted case-based learning combined with diagnosis and treatment guidelines. The other one was the control group, which performed the traditional clinical teaching mode. After 4 weeks, the assessment and satisfaction evaluation were carried out among the two groups. SPSS 19.0 was used for t test and Mann-Whitney test. Results:Students in observation group showed significantly better ability of physical examination and case analysis than those in the control group. The satisfaction degree of the students in the observation group was significantly higher in terms of diagnosis and treatment standard, clinical thinking, problem solving ability, self-learning ability and personal profession benefits than that in the control group.Conclusion:Case-based learning with diagnosis and treatment guidelines is an ideal teaching method combining theory with practice perfectly, which can significantly improve the effect of clinical teaching of standardized residency training in the department of rheumatology and immunology.

ABSTRACT

ObjectiveTo investigate the expression and significance of CD28- cells, CD4+ and CD8+T lymphocytes in the peripheral blood and synovial fluid in patients with rheumatoid arthritis ( RA ). Methods The expression of CD28, CD4+, CD8+ T lymphocytes and inducible co-stimulator(ICOS) in the peripheral blood and synovial fluid in 45 patients with RA were detected by three-color flow cytometry. Independent sample's t test was used for statistical analysis between the two groups. ResultsSynovial fluid CD4+CD28+ICOS+, CD4+CD28- ICOS+ , CD8 + CD28 + , CD8 + CD28 + 1COS+ T lymphocytes were significantly increased than the peripheral blood in RA patients[(36±19)% vs (15±8)%, t=-4.234, P<0.01; (2.1±2.2)% vs (0.6±1.4)%, t=-3.143, P<0.01; (62±15)% vs (47±18)%, t=-2.885, P<0.01; (9±9)% vs (3±3)%,t=-2.131, P<0.05], Synovial fluid CD8+CD28-T lymphoc-ytes were significantly reduced than the peripheral blood[(38±15)% vs (54±18)%, t=2.975, P<0.01], Synovial fluid CD8+ CD28-ICOS+, CD4+CD28+and CD4+ CD28- T lymphocytes had no significant difference than the peripheral blood (P>0.05). Compared with peripheral blood in the same patients with RA, CD4+CD28+ ICOS+, CD8+ CD28+ T lymphocyteswere significantly increased[(38±18)% vs (16±10)%, t=-4.065, P<0.01 ; (61±16)% vs (41±21)%, t=-4.065,P<0.01], CD8+CD28-T was significantly reduced[(39±16)% vs (59±21)%, t=2.949, P<0.01]. The level of CD4+ CD28-, CD8+ CD28-, CD28-ICOS+ T lymphocytes in the active and remission patients with RA was not significantly different (P>0.05). ConclusionSynovial fluid CD28T lymphocyte subsets disturbance and the abnormal expression of ICOS in patients with RA may play important roles in the mechanism of joint damage.

ABSTRACT

Background: The side effects of glucocorticoid in treatment of systemic lupus erythematosus (SLE) have been the focus of debate, and our preliminary study indicates that ginsenosides can enhance the efficacy of dexamethasone. Objective: To observe the effects of ginsenosides combined with prednisone in SLE patients. Design, setting, participants and interventions: A total of 60 SLE patients from Department of Rheumatology and Immunology, Changhai Hospital, Second Military Medical University, were randomly divided into treatment group and control group, with 30 patients in each group. Patients in the treatment group were given routine treatment with prednisone plus ginsenosides, while those in the control group were given routine treatment with prednisone plus placebo. They were all treated for 3 months. Main outcome measures: After three-month treatment, syndrome score in traditional Chinese medicine (TCM), total response rate and symptom improvement rate were measured and evaluated. Results: Twenty-eight cases in treatment group and twenty-seven cases in control group were included in analysis. The total response rates in the treatment group and control group were 89.28% and 66.67% respectively, and there was a significant difference between the two groups (P<0.05). After treatment, the TCM syndrome scores in the two groups were lower than those before treatment (P<0.01), and prednisone plus ginsenosides was better in decreasing the TCM syndrome score than prednisone plus placebo (P<0.05). The symptoms were improved in the treatment group as compared with the control group (P<0.05). Conclusion: Prednisone combined with ginsenosides can increase the clinical effective rate and improve the clinical symptoms of SLE patients.
