Objective To investigate the role of soluble cytotoxic T-lymphocyte associated antigen-4 (sCTLA-4) in the pathogenesis of myasthenia gravis (MG) in Fujian province.Methods A total of 80 patients with MG and 80 sex-and age-matched healthy controls were enrolled in the study .MG patients were divided into non-glucocorticoid treatment group and glucocorticoid treatment group , and the latter was further divided into immunosuppressive therapy group and thymusectomy group .Concentrations of sCTLA-4 in ser-ums from above mentioned groups were measured by enzyme-linked immunosorbent assay (ELISA).Results The concentrations of sCTLA-4 in both non-glucocorticoid treatment group and glucocorticoid treatment group were significantly higher than those in the healthy control group (6.03 ng/ml±3.58 ng/ml, 3.44 ng/ml± 2.36 ng/ml vs.0.49 ng/ml±0.95 ng/ml) (χ2=100.67, P<0.001), but sCTLA-4 concentrations in glu-cocorticoid treatment group were lower than those in non-glucocorticoid treatment group (Z=-3.37,P=0.001).With the treatment of glucocorticoid, the sCTLA-4 concentrations were reduced (6.03 ng/ml± 3.58 ng/ml vs.4.56 ng/ml±2.08 ng/ml;t=3.10, P=0.005), and the concentrations of sCTLA-4 were also decreased after thymusectomy therapy (3.86 ng/ml±2.53 ng/ml vs.2.59 ng/ml±2.37 ng/ml; Z=-2.21, P=0.04).However, there was no significant difference in the concentrations of sCTLA-4 before and after immunosuppressive drugs treatment (Z=-1.26,P=0.21).Conclusion The concentration of sCTLA-4 was increased in patients with MG , but with the treatment of glucocorticoid or thymusectomy it could be reduced .

Objective To research the relationship between anaemia and inflammatory in patients with heart failure .Methods 284 cases of patients with heart failure were enrolled and divided into 2 groups (anaemia group and non‐anaemia group) .The serum levels of of brain natriuretic peptide (BNP) ,high‐sensitivity C‐reactive protein (hs‐CRP) ,blood urine nitrogen (BUN) and creati‐nine (Crea) were measured ,and the results were analyzed .Results The levels of BNP ,hs‐CRP and Crea of anaemia group were sig‐nificantly higher than those of non‐anaemic group (P<0 .01) .The results of logistic regression demonstrated that hs‐CRP was in‐dependently associated with anaemia (P=0 .021) .Conclusion The occurrence and development of inflammation are independently associated with anaemia in the patients with heart failure .

OBJECTIVE To comprehend the changes in the spectrum of clinically isolated pathogenic bacteria and their drug resistance,and to analyze their tendency.METHODS Totally 5746 pathogenic bacteria isolated from clinical samples of the inpatients in our hospital during 1997-2004 and their drug resistance was statistically(analyzed).RESULTS Most of clinically isolated pathogenic bacteria were Gram-negative.The detected rate of Gram-positive bacteria tended to rise,while the detected rate of fungi obviously increased year after year.Gram-positive cocci and Gram-negative bacilli were resistant to commonly used antibacterials in different degrees,(especially) to ampicillin.The sensitive rate of Gram-positive bacteria was high to vancomycin,while the sensitive rates of Escherichia coli and Klebsiella pneumoniae to imipenem were high.CONCLUSIONS The structure of(nosocomial) infection(pathogens) and their drug resistance patterns are changing continuously.It should be(emphasized) to inspect(bacterial) tolerance in order to select antibacterial reasonably.

Objective To establish the rheumatoid arthritis (RA) mouse model induced by glucose-6-phosphate isomerase (GPI),and explore the mechanism of GPI in RA.Methods Totally 36 DBA/1 mice were randomly divided into three groups:test group (injection GPI),positive group (injection of bovine collagen Ⅱ),and negative group (saline).The rates and changes of weight were observed.The score of the arthritis,the ankle histopathological changes and serum GPI content were detected.Results Toes swollen slightly,joint swelling,deformity and accompanied by block were appeared at 35th day in the test group.Compared to the control group,the rates and changes of weight in test group showed a significant difference (P ＜ 0.05).The score of arthritis was showed by x ± s.Compared to the negative group,the test group and positive group were showed significant difference (P ＜ 0.05).A lot of lower synovial lining exudate macrophages,fibroblasts,and other inflammatory cells were increased in the test group.The GPI content in the test group [(0.39 ±0.11)μg/ml] was significantly higher than the negative group [(0.10± 0.06) μg/ml,P ＜ 0.05].Conclusions GPI could induce rheumatoid arthritis in mice.It provides the experimental basis to diagnose RA.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

Eight cases of hypothyroid myopthy admitted in Zhanshan Hospital Xiamen University from 1995 to 2011 were retrospectivrely analyzed.The main clinical features were proximal muscle weakness,susceptibility to fatigue,and elevation of muscle enzymes.Electromyography revealed no specific findings.All patients obtained clinical recovery after thyoid hormone replacement.Hypothyroid myopathy should be considered in cases of muscle weakness and elevation of muscle enzymes.

Objective The aim of this study was to investigate which inflammatory markers allow an accurate differentiation of septic and gouty arthritis.Methods In 2013 January to 2014 January 33 patients with septic arthritis and 29 patients with gouty arthritis.Detected white blood cells,C-reactive protein and uric acid of inflammatory markers in plasma and tested lac-tate,glucose,uric acid,lactate dehydrogenase and white blood cell count inflammatory markers in the synovial fluid.MedCalc 13.0 software were used for statistical analysis.Results There were no significantly different between serum C-reaction protein and WBC counts with two groups.Synovial lactate showed the greatest diagnostic potential (AUC=0.898,sensitivi-ty=96.9%,specificity=72.4%)followed by serum uric acid (AUC=0.818)and synovial uric acid (AUC=0.808).Con-clusion Lactate in the synovial fluid has excellent diagnostic potential to differ septic arthritis from gouty arthritis.Synovial lactate levers above 1.7 mmol/L almost proofed septic arthritis.

Objective To explore the impact of different specific body positions on blood pressure and heart rate.Methods The blood pressure and heart rate of 178 healthy teachers and students was tested with BIOLIGHT M69 in different body positions.Results ①Blood pressure and heart rate were significantly higher in squatting position than in other three specific positions(sitting position, supine position, and standing position) (P<0.01). ②The blood pressure and heart rate were going up from standing position, and standing position with right arm lifting, to standing position with arm weight lifting positions (P<0.01). Conclusion The change of special body positions resulted in change of blood pressure and heart rate.
