ABSTRACT

Objective To analyze the frequency of interleukin (IL)-22+CD161+CD4+ T cells in the peripheral blood mononuclear cells (PBMCs) in rheumatoid arthritis (RA) patients compared with healthy control subjects and investigate the relationship of IL-22+CD4+CD161+ T lymphocyte frequency changes with RA disease activity.In addition to explore the pathogenesis of RA,and to look for new treatment targets for RA.Methods Twenty-one RA cases were included in the Department of Rheumatology of Tangshan Gongren Hospital from 2017 to 2018.Fourteen patients were female and 7 were male with the age ranged from 36 to 74 years old.The average age of this group of patients was (55±10) years,the average disease course was (60±50) months.All patients fulfilled the classification criteria of American College of Rheumatology [American College of Rheumatology (ACR)].Twenty-one subjects were enrolled as the control group,all of them came to Tangshan Gongren Hospital for regular health check-up.Fifteen subjects in the control group were female and 6 were male.Their age ranged between 40-78 years old with the average age of (55±9) years.IL-22+CD4+CD161+ T cells in PBMCs were detected by flow cytometry.The frequency variation of different CD4+CD161 + T was compared between case and control groups.The correlation was studied between the frequency and RA disease activity score (DAS28),tender joints number,swollen joints number,red blood cell sedimentation rate,high sensitive C reactive protein and white blood cell counts,red blood cell counts,platelet counts,IgG,IgA,IgM,complement C3 level,complement C4 level.T-test or Mann-Whitney U test were used for single-factor analysis,Pearson's test was used for correlation analysis.Results The percentage of RA group secreted CD4+ T cells (0.33± 0.20)% of INF-γand IL-22,CD4+ T cells (0.51±0.29)% of IL-22,and CD4+CD161+ T cells of IL-22 simultaneously.The number (0.55 ±0.28)% was.significantly higher than that of the healtby control group [(0.22±0.14)%,(0.25±0.18)%,(0.36±0.24)%],and the differences were statistically significant [P=0.002,P=-0.0.45,P=0.026].Conclusion The percentage of IL-22+CD4+CD161+ T lymphocytes in the peripheral blood monocytes in RA patients is significantly higher than that in the healthy controls.The results of this study suggest that IL-22+CD4+CD161+ T lymphocytes in RA patients maybe related to RA disease activity and joint lesions.

ABSTRACT

Objective To study the theraputic effect of cyclophosphamide,glucocorticoid combined with sildenafil on pulmonary hypertension in systemic lupus erythematosus(SLE?PAH) patients,and to analyze the prognosis adverse factors. Methods Forty?six cases patients with SLE?PAH from Tangshan Gongren Hospital from January 2009 to January 2015 were selected as research subjects. All patients were treated with prednisone, cyclophosphamide and sildenafil,and the course of treatment was 24 weeks. The treatment effect was observed, the systemic lupus erythematosus disease activity score(SLEDAI),6 minutes walk distance and heart function before and after the treatment were compared. The effective and uneffective patients'clinical and test information were compared,and the prognosis adverse factors were analyzed. Results After 24 weeks treatment,the total ef?fective rate was 78. 3%(36/46). Pulmonary artery systolic pressure(PASP) dropped from (59±16) mmHg be?fore treatment to (45±15) mmHg after treatment,there was significant statistical difference(t=-4. 539,P<0. 01). SLEDAI dropped from (6. 6±2. 3) points to (2. 4±0. 8) points,,there was significant statistical differ?ence(t =11. 680,P<0. 01). The 6 minutes walk distance rose form (402±96) minutes to (465±97) minutes, there was significant statistical difference( t=-3. 137,P<0. 01) . Cardiac function improved significantly,there was significant statistical difference( P<0. 01) . There were 10 cases uneffective and deterirated patients,with the age of (42±6) years,36 cases effective patients with the age of (33±4) years,the difference was statistically significant( t=-5. 423, P<0. 01 ) . Uneffective and deterirated patients' anti?RNP antibody positive rate was 90. 9%( 9/10 ) , significantly higher than the effective patients ( 52. 8%( 19/36 ) ,χ2 = 4. 552, P<0. 01 ) . Conclusion Cyclophosphamide, glucocorticoid combined with sildenafil has obvious effect on patients with SLE?PAH. PASP,heart function and 6 minutes walk distance are the important indicators of prognosis. Anti?RNP antibody and age are the adverse prognostic factors.

ABSTRACT

BACKGROUND:The non-specific immune suppression method is generaly used for treatment of systemic lupus erythematosus, but poor prognosis, such as infection and high recurrence rate, exists. OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem cel transplantation on systemic lupus erythematosus in mice. METHODS:Sixteen mice with systemic lupus erythematosus were equivalently randomized into control and experimental groups, or then subjected to passage 3 bone marrow mesenchymal stem cel transplantation or the equal volume of normal saline via the tail vein, respectively. Mouse urine samples were colected to detect urine protein levels by Bradford method. Blood samples from the tip of the mouse tail were extracted to detect serum anti-ds-DNS antibody concentration by radioimmunoassay. Mouse kidney tissues were taken and observed pathohistologicaly through hematoxylin-eosin staining and immunohistochemistry staining under microscope. Flow cytometry was used to detect the expression of CD4+CD25+T cels in the inner canthus blood, fresh spleen and thymus. RESULTS AND CONCLUSION:Within 10 weeks after cel transplantation, the urine protein levels in the two groups were gradualy increased, and the rising velocity was higher in the control group than in the experimental group. From the 4th to 10th week, the urine protein levels in the experimental group were significantly lower than those in the control group (P 0.05). The serum anti-ds-DNA antibody concentration in the experimental group was significantly lower than that in the control group (P < 0.05). Taken together, bone marrow mesenchymal stem cel transplantation can improve the pathological damage in systemic lupus erythematosus mice, and has a certain therapeutic effect on systemic lupus erythematosus.

ABSTRACT

Objective To investigate the clinical and laboratory characteristics of anticentromere antibody (ACA)and anti-SSA antibody expressions in patients with Primary Sj(o)gren's Syndrome (PSS). Methods Twelve PSS patients with ACA positive but SSA negative(ACA PSS)and 19 PSS patients with SSA positive but ACA negative(SSA PSS)were enrolled into the study and classified into two groups. We compared the age,laboratory data,occurrence of Raynaud's phenomenon(RP),and histological changes in minor labial salivary glands biopsies of the patients from two group. Results The mean age of the ACA PSS group(68.4 ± 7.9)years was significantly higher than that of the SSA PSS(54. 6 ± 16. 2)years group(P < 0. 05). Serum IgG level of ACA PSS group(17. 89 ±4. 08)g/L was close to the normal range,which was significantly lower than that of SSA PSS(27.90 ±6. 72)(P <0. 01). Leukocytopenia was less frequently observed in ACA PSS than in SSA PSS(P < 0. 05),the difference between two groups was statistically significant. We also found more frequent RP in the ACA PSS group than SSA PSS group(P < 0. 05). Conclusions Our data confirm that ACA positive PSS differs from SSA positive PSS at several clinical respects and laboratorial examinations.
