Objective To improve the understanding of progressive pseudorheumatoid dysplasia (PPD). Methods The clinical and roentgeno graphic features of two patients with PPD diagnosed in our department were analysed, and the related literature was reviewed. Results The patients first experienced the osseous swelling in phalangeal joints of both hands in childhood, and progressively almost all joints were involved. The spine was also involved. By analyzing the clinical information of 53 cases, it was found that PPD involved both male and female similarly. The ages at onset of first symptoms, were from 1 to 10 years, and in seventy seven percent of patients the ages were 3 years to 5 years. Clinical features included progressive involvement of the major joints, including small joints of the hands, hips, knees, ankles, wrists and shoulders. Premature osteoarthritis developed in early adult life, and it was the major reason of disability. 38% of patients were short in stature. The roentgenographic features consisted of generalized platyspondyla with irregular delineation of the endplates of the vertebral bodies, varying degrees of epiphyseal involvement with enlargement of the large joints, metacarpal heads and phalanges, secondary degenerative arthritis with periarticular osteoporosis. The symptoms of PPD were similar to those of rheumatoid arthritis (RA), but differed from it by the Absence of synovitis and other inflammatory changes, and radiographically by the Absence of destructive changes and the presence of dysplastic bone changes. There was no specific treatment for cure. Conclusion PPD is a rare autosomal recessive skeletal disorder associated with WISP3 gene mutations. Its clinical features and typical roentgenographic features are helpful to the diagnosis.

BACKGROUND: The repair of periodontal tissue is dependent on the number and proliferation and differentiation abilities of periodontal ligament (PDL) cells. PDL cells have the potentiality of multi-directional differentiation such as cementoblast,osteoblast and fibroblast to fonn cement, alveolar bone and periodontal ligament and finally achieve periodontal tissue regeneration.OBJECTIVE:To observe the effects of Shuanghuangbu extract on the proliferation and differentiation of PDL cells.DESIGN:Observation trail.SETTING:Central Laboratory of Wuxi Third People's Hospital. MATERIALS: Periodontal tissue was provided voluntarily by the healthy young patients with deformity correction, and golden thread,skullcap,and rhizoma drynariae by the National Institute for the Control of Pharmaceutical and Biological Products.METHODS: The experiment was conducted in the Central Laboratory of Wuxi Third People's Hospital from July to October 2003.The crushed golden thread.skullcap,and rhizoma drynariae were mixed with distilled water at ratio of 1:10 (m:V),and refluxed in boiling water for 5 hours.The extract was collected,and after colation,the residue was refluxed in boiling water for another 3 hours. Both extract was blended, rotary evaporated and condensed, finally the liquid extract of 3 kg/L was obtained.There were 8 groups in the study including golden thread group, skullcap group,rhizoma drynariae group,golden thread plus skullcap group,golden thread plus rhizoma drynariae group, skullcap plus rhizoma drynariae group, Shuanghuangbu group and control group. PDL cells were cultured/n vitro assisted with Shuanghuangbu.The proliferation of cells was detected with MTT method and the ratio of collagen content in total protein was evaluated with hydroxyproline (HP).MAIN OUTCOME MEASURES:A value of proliferated PDL cells and the proportion of collagen protein in total protein.RESULTS:①Proliferation of PDL cells:Except golden thread group,all Chinese medicine promoted the proliferation of PDL cells significantly compared with control group (P＜0.05). The A value of Shuanghuangbu group was significantly increased.A value was increased with time and reached the peak on day 5.There were significant differences among each group at different time (P＜0.05).②Ratio of collagen content in total protein:Except golden thread group,the percentage was significantly increased by other Chinese medicines compared with control group (P＜0.05), especially Shuanghuangbu. The percentage was increased with time and reached the peak on day 5. There were significant differences among each group at different time (P＜0.05). CONCLUSION:The findings suggest that as a traditional Chinese herb,Shuanghuangbu can significantly stimulate the proliferation and differentiation of PDL cells.and increase the proportion of collagen content in total protein.It may act as an ideal Chinese medicine helper factor for the regeneration of PDL cells.

Objective To determine whether thalidomide can maintain remission after discontinuing the treatment of etanercept in ankylosing spondylitis (AS). Methods One hundred and five patients with active AS treated with etanercept 50 rag/week for 12 weeks and attained an ASAS20 response at week 12. They were randomly assigned to receive thalidomide 150mg/night, sulfasalazine (SASP) 2.0 g/d, or non-steroidal anti-inflammatory durgs (NSAIDs) only. All patients were followed monthly for BASDAI, BASFI, PGA and spinal pain VAS. A Kaplan-Meier survival analysis was used to calculate the probability of a relapse. Results One hundred patients completed the follow-up. Thirty patients were treated with thalidomide, 33 patients with SASP and 37 patients with NSAIDs only. The mean follow-up time was 5.1 months and the longest time was 12 months. At the end of the follow-up, the percentage of patients who maintained remission in the thalidomide group was 40%, much higher than SASP group (15%) and NSAIDs group 11% (P=0.0265 and 0.0053 respectively). No difference was found between the remission rate of SASP and NSAIDs only group (P=0.5881). Conclusion Thalidomide can successfully maintain remission of AS after discontinue etanercept treatment.

Objective To study the imaging features of sacroiliac joints(SIJ) in patients who were misdiagnosed as spondyloarthritis(SpA).Methods A total of 34 patients with chief complaint of back pain and misdiagnosed as SpA from January 2007 to April 2013 in Department of Rheumatology Chinese PLA General Hospital were enrolled.The imaging,clinical manifestations,laboratory examinations data were analyzed.Result The main reason for misdiagnosis as SpA was because of sacroiliitis presenting on imaging.The final diagnoses included 24 patients as SIJ infection,4 patients as neoplastic diseases,2 patients as metabolic bone diseases,2 patients as sacroiliac joint degeneration,1 patient as gout of sacroiliac joint,1 patient as diffuse idiopathic bone hypertrophy.For patients with infection,there were 10 patients receiving X-ray and 22 patients receiving CT of SIJ.However,5 and 7 patients had negative results respectively.These patients with infection had abnormalities in MRI including all with bone marrow edema,21 patients with erosion of bone and joint,22 patients with muscle involved.As to the patients with malignancies,SIJ CT scan appeared normal.Bone marrow edema and erosion in MRI were found in all neoplasm patients expect one as ependymoma.Adjacent muscles were involved in the patient with Ewing's sarcoma.Either X-ray or CT in other patients demonstrated obvious abnormalities,but only mild erosion of bone was found in MRI.Conclusion Bone marrow edema of SIJ in MRI represented not only in patients with SpA.Rheumatologists should analyze the clinical manifestations and laboratory examinations comprehensively in order to avoid the misdiagnoses.

ObjectiveTo explore the diagnostic and differential diagnostic points in a patient with rheumatoid arthritis (RA) complicated with fever and pulmonary diseases. MethodsFull clinical analysis was performed for a 55-year old patient with arthritis, fever, and wheeze. ResultsThe clinical pictures of the patient were consistent with those of RA. Computed tomography(CT) revealed interstitial lung diseases and intrapulmonary cavities. Antifungal agents were given experimentally, and the intrapulmonary cavities disappeared finally, thus the patient was diagnosed as RA, concurrently complicated with interstitial lung disease and pulmonary fungal infection. ConclusionThe possibility of pulmonary fungal infection should be considered in RA patients who presented with fever and intrapulmonary cavities.

Objective To understand the features of immunoglobulin G4-related diseases and to improve its diagnosis and treatment.Methods The clinical data of 20 cases discharged from our hospital were analyzed retrospectively.Results Twenty cases with IgG4 related diseases were reviewed retrospectively.IgG4-related diseasesis more prevalent in male than in female (14∶6),and the mean age was 58 years.Pancreas and bile ducts were the most commonly affected organs,2 and more than 2 organs were involved in 17 patients.All patients had significantly elevated serum immunoglobulin G4.Histopathological findings included diffuse tissue fibrosis with extensive lymphoplasmacytes infiltration.On immunohistochemical staining,the ratio of IgG4-positive plasma cells to IgG-positive plasma cells was higher than 40％.One patient deceased and one patient was left untreated,other patients responded well to the treatment.Conclusion There is no characteristic clinical symptoms for IgG4-related diseases,and serum immunoglobulin G4 is the essential diagnostic method in suspected cases.IgG4-related diseases can be well controlled with prompt use of glucocorticosteroid.

In this report, we utilized N-Acetylmuraminidase (AcmA) to develop a whole-cell catalyst of endo-beta-1, 3-1, 4-glucanase in Lactococcus lactis. The PCR-amplified full-length acmA gene from L. lactis MB191 was fused with the green fluorescent gene (gfp), followed by ligating the chimeric acmA-gfp into the Escherichia coli-L. lactis shuttle expression vector pMG36k, yielding the recombinant plasmid pMB137. SDS-PAGE analysis showed that the constitutive expression of AcmA-GFP fusion protein in the L. lactis AS1.2829 construct harboring pMB137 (named MB137), with the predicted Mr of 74 kD. Western blotting, GFP specific fluorescence intensity assays and flow cytometry analysis confirmed that AcmA-GFP was immobilized on the outer membrane, which constituted approx. 35% of the total intracellular fusion protein. Furthermore, acmA was fused with a PCR-amplified encoding fragment of the endo-beta-1, 3-1, 4-glucanase gene (gls) from Bacillus sublitis BF7658, resulting in the recombinant plasmid pMB138. By transferring pMB138 into L. lactis AS1.2829, the derived L. lactis MB138 expressing the AcmA-GLS fusion enzyme exhibited a distinct whole-cell glucanase activity (by 12 U/mL) compared to the control strain, indicating AcmA had served as a functional anchoring motif to immobilize the heterologous enzyme on the cell surface of L. lactis.
