Results The median onset age of the 4 patients(2 females and 2 males)was 34 years old.Typical clinical manifestations included joint symptoms,flu-like malaise and erythematous rash.Anti-Bl9 IgM antibodies were all positive in 4 patients.B19 DNA was detected in blood samples of 3.Other types of arthritis were excluded. No relapses were noticed after followed-up of 1～3 years.Conclusion The Anti-B19 lgM and B19 DNA should be detected in patients suffer from arthritis with unknown origin.

Objective To evaluate the diagnostic specificity and sensitivity of anti-p68 antibody in rheumatoid arthritis (RA), and to analyze the relationship between anti-p68 antibody and the activity of RA . Methods Anti-p68 antibody was tested in the serum of 183 RA patients and 195 controls by indirect immunofluorescence (IIF). The clinical characteristics of RA between anti-p68 positive group and negative group were compared. Results ① The positive rate of anti-p68 antibody was 67.8% (124/183) in RA, 14.9% (17/114) in other rheumatic diseases and none in normal controls (0/81). Anti-p68 antibody was different from other auto-antibodies found in RA. ② Its sensitivity was 67.8% and specificity was 91.3% for RA, positive prediction rate was 87.9% and negative prediction rate was 75.1%. ③ There was statistic difference between the positive group and negative group in disease duration, RF and degree of X-ray changes. Conclusion ① Anti-p68 antibody is a new and specific serum maker for diagnosis of RA. ② The antibody is correlated with disease duration, RF and X-ray changes.

Objective To examine the role of synthetic cyclic citrullinated peptide (CCP) in T cell autoreactivity in rheumatoid arthritis (RA) by detecting T cell proliferation. Methods Twenty-nine RA, 8 primary Sjo gren syndrome (pSS) and 16 osteoarthritis (OA) patients were included in this study. Proliferation of T cells was measured by methyltetiazolium incorporation following incubation with CCP. Results T cell response to CCP was more common in RA patients than in controls. The response rate to CCP was higher in late RA than in early RA. However, the response wasn′t associated with disease activity. A strong association between T cell proliferation and RF, anti-CCP antibody was observed. Conclusions T cell proliferation in response to CCP was found in the majority of RA patients, even in early RA, suggesting that the citrullinated peptide play an important role in the pathogenesis of RA.

Objective:To evaluate the significance of the combination of rheumatoid factor (RF) and anti-filaggrin antibodies (AFAs) in the diagnosis of rheumatoid arthritis (RA). Methods:Sera from 266 RA patients and 186 controls were studied. RF and some kinds of AFAs (including antikeratin antibodies, anti-perinuclear factor and anticyclic citrullinated peptide antibodies) were detected using immunofluorescence and ELISA respectively. The distributions of these antibodies were compared to determine the significance of the combination of RF and AFAs. Results:The sensitivity and secificity of RF for the diagnosis of RA were 65.8% and 81.8% respectively, as compared with those of anti-CCP or RF positive were 86.5% and 80.6% respectively. Only a slight change was found in the secificity and negative predictive value between them. RF could not be detected in 91 patients while 64.8% of them could be found to have at least one kind of AFAs. Conclusion:AFAs, particular anticyclic citrullinated peptide antibodies, could be helpful for the diagnosis of RA especially in RF-negative patients.

Objective To evaluate the clinical results of surgical treatment of isolated fractures of the sustentaculum tali of calcaneus via medial approach.Methods The data of 23 patients with isolated fractures of the sustentaculum tali of calcaneus was retrospectively analyzed who were treated with open reduction and internal fixation with cannulated screw or Kirschner wire via medial approach from September 2006 to March 2011.There were 19 males and 4 females,with an average age of 26.3 years (range,17-41 years).Associated injuries included 4 cases of talus fracture,4 of metatarsal fracture,and 3 of cuboid fracture.The functions of hiudfoot were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores pre-operation and post-operation respectively.Results Fifteen patients got followed up with an average 20.5 months (10-56 months).Thirteen patients were rated as good,2 as excellent,and the excellent and good rate was 100％(15/15).All the fractures were stabilized reliably,and got clinical union with no obvious complications occurred.Time of fracture union was 8-10 weeks,with an average of 8.5 weeks.Three patients felt mild transient pain during the recovery of walking,but their pain disappeared quickly after physical therapy.No patients developed wound infection,nonunion and other complications.Conclusion For isolated fractures of the sustentaculum tali of caleaneus with articular surface displaced greater than 1 mm or involving the articular surface of middle subtalar joint,open reduction and internal fixation operation via medial approach under direct visualization is recommendable.

Objective To explore the diagnostic value of anti-cyclic citrullinated peptide (CCP) 3.1 IgG/IgA antibody detected by enzyme-linked immunosorbent assay (ELISA) in patients with rheumatoid arthritis (RA).Methods The ELISA was used to measure the anti-CCP3.1 antibody in the serum of 169 RA patients,100 patients with other rheumatic diseases (including systemic lupus erythematosus,Sjogren's syndrome and osteoarthritis) and 72 healthy controls.The diagnostic value of CCP3.1 was assessed and compared with the second generation of anti-CCP IgG (CCP2) antibody,the correlations between anti-CCP3.1 antibody and the clinical and laboratory parameters were analyzed.Two-independent samples t test,chi-square test and Spearman's correlation were adopted for statistical analysis.Results ① The average cut-off concentration of anti-CCP3.1 antibody was (1122±1429) U/ml in RA,(13±14) U/ml in other rheumatic diseases and (6±5) U/ml in healthy controls.② The area under curve of ROC for anti-CCP3.1 antibody and anti-CCP2 antibody were 0.923 and 0.936 respectively.There was no difference between the sensitivity (82％ vs 79％)and specificity (97％ vs 99％) of anti-CCP3.1 antibody and anti-CCP2 antibody.The Kappa values between anti-CCP3.1 antibody and anti-CCP2 antibody was 0.763.③ We also found that anti-CCP3.1 antibody was positive in 20％(7/35) of anti-CCP2 antibody negative,43％(18/42) of RF negative,62％(47/76) of AKA negative,71％(49/69) of APF negative and 13％ of autoantibodies negative patients,indicated that antiCCP3.1 antibody had a potential value in the diagnosis of serum negative patients with RA.④ The presence of anti-CCP3.1 antibody was correlated with RF,HRF-IgG,APF,AKA,GPI and IgA (P＜0.05),except disease activity.Conclusion The sensitivity of anti-CCP3.1 antibody is slightly higher than anti-CCP2 antibody.The Anti-CCP3.1 antibody is a very valuable parameter for the diagnosis of RA,especially in serum negative patients.

Objective To investigate the effects of low molecular heparin(LWMH)on cytokines(TNF-?,IL-1? and IL-10)in blood plasma and bronchoalveolar lavage fluid of invasive pulmonary aspergillosis(IPA)mice.Methods The neutropenic IPA mouse models were established by administration of cyclophosphamide for immunologic function inhibition and intranasally challenge with Aspergillus fumigatus conidia(1?106 conidia/mouse).One hundred and twenty mice were randomly divided into 4 groups:normal control,IPA model,normal saline+LWMH and IPA+LWMH group.Normal saline+LWMH group and IPA+LWMH group received LWMH(subcutaneous injection,1 000 IU/kg,qd?2 d).Normal control and IPA model group received normal saline instedad of LWMH.At 4,8,12,24 and 48 h after inoculation,six mice were randomly taken from each group to be sacrificed.ELISA method was used to determine the concentrations of TNF-?,IL-1? and IL-10 in blood plasma and BALF.Results TNF-?,IL-1? and IL-10 in blood plasma and BALF increased significantly several hours after inoculation of conidia in IPA model and IPA+LWMH group.There were significant higher concentrations of TNF-? and IL-1? in blood plasma and BALF in IPA+LWMH group than in IPA model group(P

Background Corneal contact lens have been widely used in vitrectomy.The corneal ring accompanying with the contact lens therefore is also much concerned.We designed a sutureless silicone corneal ring to renew a suturing?ring,but its detection of physicochemical properties and hiocompatihility is necessary for clinical application. Objective This study was to investigate the physicochemical properties and biocompatibility of the newly designed sutureless silicone corneal ring. Methods The Shore hardness,tensile stress-strain tests,tear strength,transmittance and the haze of the novel silicone ring were tested.The bioeompatibility of sutureless silicone corneal ring to corneal epithelial cells was evaluated by determining cytotoxieity.The ring was implanted into the counjunctival soc of 6 Japanese white rabbits for 4 hours to determine its stimulation response by measuring the area of corneal fluorescence staining,and then the ring was placed on the skin surface of 6 SD rats for 4 hours to assess the presence of allergic reaction by calculating the swelling area of skin. Results The new sutureless silicone corneal ring showed good physiological features with a Shore hardness of 63.4 degree,tensile strength more than 5.86 MPa,elongation＞100%and tear strength 34 kN/m.The transmittance of 3 legs in the ring was more than 93%;however,the haze was less than 0.1%.Cytotoxicity of the ring was 3.1 1×10-6%.No obvious corneal fluorescence staining was seen at any time point in all the rabbit eyes in the stimulating test.Furthermore,there was not any skin swelling in various time points in all the SD rats in the allergy test. Conclusion The physicochemical properties of the silastic used in our newly designed sutureless silicone cornea ring can meet the demands of the ring.The biological evaluation complies with the ISO i0993-1 international standards and meets the demands of the organism.Thus,it is all ideal material to use in constructing the corneal ring.
