ABSTRACT

Objective:To investigate the level and the influencing factors of blood uric acid in monks and nuns in Wutai Mountain area, and to explore the relationship between blood uric acid level and BMI and blood lipids levels.Methods:Physical examinations and laboratory tests were performed on monks and nuns in Wutai Mountain area. There were 207 males and 261 females. Physical examination includes height, weight, blood pressure, blood uric acid, blood lipid, blood glucose and other indicators. The blood uric acid level was measured using the uricase method. Chi-square test for trend, and t test were utilized for statistical analysis. Results:The average blood uric acid level of the monk and the nun was (372±6) μmol/L and (290±4) μmol/L, respectively. Obviously, the average blood uric acid level of the monk was significantly higher than it in the nun ( t=11.636, P<0.01). The total incidence rate of hyperuricemia, which was diagnosed when the blood uric acid level was higher than 420 μmol/L in males and the blood uric acid level was higher than 360 μmol/L in females. In particular, the incidence rate of hyperuricemia was much higher in the monk (24.3%, 50/207) than in the nuns (13.4%, 35/261) ( χ2=8.966, P<0.01) . Analysis by age, the prevalence of hyperuricemia in men was 20.3%(42/207) before the age of 50, which was higher than that after the age of 50 (3.9%, 8/207) ( χ2=26.3, P< 0.01); The prevalence of hyperuricemia in women before the age of 50 was 2.7%(7/261), which was lower than that after the age of 50 (10.7%, 28/261) ( χ2=13.51, P<0.01). The uric acid level of men and women between 50-60 years old, showed the opposite trend. The level of uric acid in men decreased and increased in women. In addition, the prevalence of triglyceride abnormalities and overweight was more significantly in monks and nuns with high uric acid than those with the normal uric acid level [71.8%(61/85) vs 45.2%(173/383), χ2=19.68, P<0.01; 54.1%(46/85) vs 19.8%(76/383), χ2=42.4, P<0.01]; while no significant difference of total cholesterol and blood glucose levels was observed between these two groups. Conclusion:There are differences in blood uric acid levels among Wutai Mountain area monks and nuns of different ages and genders. The level of blood uric acid in male is significantly higher than that in female. Lipid metabolism and over weight are closely related to elevated level of the uric acid, which might be the risk factors of uric acid abnormality in Wutai Mountain population.

ABSTRACT

Objective To evaluate the clinical significance of serum thrombospondin-1 (TSP-1) in systemic lupus erythematosus (SLE), and explore its possible involvement in SLE pathogenesis. Methods One hundred and thirty-eight patients diagnosed with SLE, including 124 cases of females and 14 males, as well as 60 healthy controls were recruited into this study. Enzyme-linked immunosorbent assay (ELISA) was used to determine serum TSP-1 expression level between the two groups. Spearman correlation analysis method was used to analyze the correlation between TSP-1 level of complement 3, complement 4, anti-double-stranded DNA, Rheumatoid factor and systemic lupus erythematosus disease activity index (SLEDAI). Results TSP-1 level in healthy control group was much higher than that in SLE patients. TSP-1 serum levels in SLE patients was positively correlated with complement 3 (r=0.386, P<0.01), complement 4 (r=0.301, P<0.01), and negatively correlated with anti-double-stranded DNA (r=-0.221, P=0.009), RF (r=-0.186, P=0.029) and SLEDAI (r=-0.273, P=0.001). Conclusion TSP-1 may play an immune-regulatory role in the development of SLE by inhibiting inflammation and autoantibody production. It could become a potential therapeutic target for the treatment of SLE.

ABSTRACT

Objective To investigate the clinical and immunological features of rapid progressive interstitial lung disease (ILD) in patients with idiopathic inflammatory myopathy (ⅡM).Methods The medical records of 146 adult ⅡM patients associated with ILD in Peking University People's Hospital from February 1996 to February 2015 were retrospectively analyzed.They were divided into three subgroups:the classic DM,PM and the clinical amyopathic dermatomyositis (CADM),and were further stratified based on with or without rapid progressive ILD (RP-ILD).Chi-squared test was used for group comparisons of categorical data and independent-sample t test for numerical data.Results ① Among 146 patients,62 (42.5%) developed RP-ILD.The prevalence of RP-ILD in CADM was signifcantly higher than dermatomyositis (DM) and polymyositis (PM).② ILD occurred after or at the same time with ⅡM in more than 90% of patients.ILD arising before or simultaneously with DM (named early-onset ILD) tended to progress rapidly.③ For the DM group,mechanic's hands,fever,lymphopenia,hypoxemia,hypoalbuminemia,and the elevation of globulin α1 were associated with RP-ILD.CADM-ILD with weakness of swallow muscles,increasing C-reactive protein (CRP) and globulin α2,decreased vital capacity and the relatively high level of segmented granulocytes in bronchoalveolar lavage fluid tended to undergo a rapid progressive clinical course.Additionally,the decreased free triiodothyronine (FT3) and the elevation of tumor markers including carcino-embryonic antigen (CEA),neuron specific enolase (NSE),cytokerantin-19-fragment (CYFRA211) and ferritin were significantly more frequent both in DM and CADM with RP-ILD (P<0.05) patients.④ According to multivariate analysis,mechanic's hands [HR =31.747,95%CI (2.367,425.817),P=0.009] and the elevation of CEA [HR =57.047,95%CI (1.140,2 854.885),P=0.043] and CRP [HR=31.568,95%CI (1.818,548.093),P=0.018] were potential predictive factors for RP-ILD in DM and CADM patients,respectively.Conclusion The prevalence of RP-ILD in CADM is higher than DM and PM.ILD usually occurs after or simultaneously with ⅡM,early-onset ILD in DM patients tends to progressive rapidly.Increased tumor markers and decreased FT3 indicate the deterioration of disease.Mechanic's hands and the elevation of CEA and CRP are potential predictive factors for RP-ILD in DM and CADM patients,respectively.

ABSTRACT

Objective To explore the effects of different doses of 5,2′,4′-trihydroxy-6,7,5′-trimethoxyflavone nanoparticles (TTF1-NP)on the apoptosis of human hepatoma cells and human normal hepatocytes,and to explore their mechanisms through endoplasmic reticulum stress (ERS)-meditated apoptosis pathway. Methods The human hepatoma cell lines (HepG2,Hep3B and PLC/PRF/5)and human hepatocytes (Chang Liver)were used as cell model, and divided into vehicle, 5-Fu and TTF1-NP treated groups with the concentrations of 50, 100 and 200 μmol·L-1 respectively. The inhibitory effects of TTF1-NP on the cell growth were assessed using MTT assay and the best inhibitory one (HepG-2)was selected as the main research cell lines.Flow cytometry was used to detect the TTF1-NP-induced apoptosis;Western blotting and immunocytochemistry were used to determine the expressions of ERS key proteins.Finally,the expressions of key proteins were detected by Western blotting after using the ERS inhibitor 4-PBA.Results Compared with vehicle group,the inhibitory rates of growth of 4 kinds of human hepatoma cells in different concentrations of TTF1-NP groups were increased (P <0.05 or P <0.01);moreover,the inhibitory effects of TTF1-NP were in a time-and dose-dependent manner.Compared with vehicle group,the apoptotic rates of the cells in TTF1-NP groups were increased in a dose-dependent manner (P <0.05 or P < 0.01 );the expression levels of ERS key proteins GRP78 and caspase-4 were increased with the increasing of the concentration of TTF1-NP (P < 0.05 or P < 0.01).The expression levels of ERS key proteins GRP78 and caspase-4 induced by TTF1-NP were inhibited by ERS inhibitor 4-PBA (P < 0.05 or P < 0.01 ). Conclusion TTF1-NP can induce the apoptosis of HepG2 cells;ERS pathway plays a central role in TTF1-NP-induced apoptosis of HepG-2 cells.

ABSTRACT

Objective To evaluate the efficacy of double filtration plasmapheresis (DFPP) combined with immunosuppressive agents (leflunomide plus methotrexate) on synovitis in magnetic resonance imaging (MRI) in patients with high active rheumatoid arthritis (RA). Methods Fifty eight patients with RA (disease duration 6 months to 12 years) were randomly divided. Thirty-one were randomized to the treatment group and 27 were randomized to the control group. All patients received leflunomide 10 mg, two times daily; plus methotrexate 15 mg orally once weekly. DFPP was performed in the treatment group once 1-2 weeks for 3-4 sessions. Control patients did not receive DFPP. All patients underwent contrast-enhanced MRI of the right wrist at the baseline and 6 months, 1 month in the treatment group. The signs including synovitis pannus, bone marrow edema and effusion were observed on MRI. The scoring of synovial hypertrophy, pannus, bone marrow edema were measured according to the outcome measures in RA MRI scoring system. Comparisons between groups were performed with paired-samples t test and independent-sample t test. Results The MRI synovitis score, MRI pannus score and MRI bone marrow edema in the treatment group was (1.4±1.6), (0.13± 0.35) and (5±4) respectively,so was significantly lower than that of the control group [respectively for (7.9± 1.3), (2.76±0.43), (16±12),P<0.01]. 53% of the treatment group satisfied both the disease activity score 28-joint assessment and MRI synovitis assessment (no enhancement of synovium or pannus, no effusion), but none in the control group (P<0.01). Significant changes at 1 month was observed in DAS28 and HAQ scores (P<0.01), but not in the MRI synovitis score, MRI pannus score, MRI bone marrow edema score and effusion in the treatment group (P>0.05). Conclusion DFPP combined with immunosuppressive agents can significantly improve synovitis in MRI in patients with high active RA. Improvement of the signs of MRI is later than that in the clinic. So imaging assessment may be necessary for accurate evaluation of disease status and selection of therapy.

ABSTRACT

Objective To investigate clinical characteristic of primary Sjogren's syndrome(pSS) with initial manifestations in the extra-gland organs. Methods Clinical data, including symptoms, laboratory parameters and complications of 85 pSS patients with initial manifestations of extra-gland organs hospitalized at the People's Hospital of Peking University during 2003 to 2006 were collected and analyzed retrospectively, as compared to those of pSS with xerophthalmia or xerostomia as initial ones. Results Mean time interval from onset to diagnosis in these patients with initial manifestations involved in the extra-gland organs was 94.5 months, higher than that in those with xerophthalmia or xerostomia as initial ones. Arthritis was manifested initially in 38 of the 85 patients (44.7 percent), peripheral leukopenia in 16 (18.8 percent), thrombocytopenia in nine (10.6 percent) and abnormal liver function in 13 (15.3 percent), respectively. Percentage of serum positive autoantibedies was higher in the patients with initial manifestation of the extra-gland organs than that in those with xerophthalmia or xerostomia as initial ones. Conclusions Initial manifestation of primary Sjogren's syndrome varies, and some patients can be initially involved in their extra-gland organs, with more proportion of arthritis than of other symptoms, and xerophthalmia or xerestomia could appear in them during the course of disease. And, xerophthalmia or xerostomia would not appear even as pSS was diagnosed in some other pSS patients. More attention should be paid to these clinical characteristics mentioned above in practice to avoid misdiagnosis.
