Objective To compare the clinical efficacy and carry out analysis on pharmacoeconomic cost-effect of three therapeutic schemes in the treatment for stroke. Methods Through a retrospective survey method, 115 stroke patients, based on different treatment methods, were divided into 3 groups:Xuesaitong group (A), carthamin yellow group (B), and Xueshuantong group (C). An analysis on pharmacoeconomic cost-effect was conducted. Results The costs of three therapeutic schemes were 1030.4 yuan, 1876 yuan, and 1545.6 yuan, respectively. The total effective rates of stroke patients in groups A, B and C were 85.37%, 88.57% and 90.04%, respectively. The cost-effect ratios of groups A, B and C were 12.07, 21.18, and 17.17. The added cost-effect ratios of groups B and C compared with group A were 264.25 and 110.32, respectively. Conclusion Xueshuantong Injection has more pharmacoeconomic advantage than Xuesaitong and carthamin yellow Injections in treating stroke.

Objective To demonstrate high mobility group box chromosomal protein 1(HMGBI) expression in synovium and joint,and to identify the role of HMGB1 in the pathogenesis of synovitis and joint destruction in adjuvant-induced arthritis(AA).Methods AA of 15 male rats were induced in SD rats by intradermal injection of 100?l Freud's complete adjuvant in the foot pad of the left hind paw.All rats were killed at the 18th day.Synovium and joints were collected for histopathology studies and determining the expression of HMGB1 by immunohistochemistry,and serum was collected for determining the expression of HMGB1 by western blotting analysis.Results Immunostaining of specimens from normal rats showed that HMGB1 was primarily confined to the nucleus of synoviocytes with occasional cytoplasmic staining.In contrast, inflammatory synovial tissues from AA rats showed a distinctly different HMGB1 staining pattern.Nuclear HMGBI expression was accompanied by a cytoplasmic staining in many mononuclear cells.The cytoplasmic HMGB1 expression in synovium of AA rats is significantly higher than that of normal rats.Additionally,HMGBI was highly expressed in the nuclei and cytoplasm of the subchondral chondrocytes and inflammatory cells in bone erosion in AA rats(P＜0.01),while fewer positive cytoplasmic staining of HMGB1 was found in chondrocytes and fewer positive nuclear staining was found in bone cells in normal rats.HMGB1 concentration was significantly higher in serum of AA rats than that in normal rats(P＜0.001).Conclusion The cytoplasmic HMGBI expression in synovium and joints is greatly upregulated;the level of HMGB1 in serum is increased in AA rats which suggests a patbogenetic role of HMGB1 in synovitis and bone destruction of adjuvant-induced arthritis.

Objective To observe the treatment of ~(99)Te-MDP on typeⅡcollagen induced arthritis (CIA)in rat,and the effect on the expression of synovial MMP-3 and TIMP-1 mRNA.To explore the mech anisms of the ~(99)Te-MDP in the treatment of rheumatoid arthritis.Methods The rats in which C1A(n=24)were divided into three group:the control group(n=8),~(99)Tc-MDP group(n=8)and Methotrexate group(n=8). Arthritis were evaluated by arthritis index and histopathological index and the expressions of MMP-3 and TIMP-1 mRNA in synovium were detected by RT-PCR.Results①The arthritis indexs of the control group, the methotrexate group,the ~(99)Tc-MDP group were increased with time.②The histopathological scnres of the control group were significantly higher than those of methotrexate group and ~(99)Tc-MDP group(P＜0.01).The histopathological scores of cartilage destruction and bone erosion of ~(99)Tc-MDP group were lower than those of methotrexate group(P＜0.05).③The levels of MMP-3 mRNA of the control group,~(99)Tc-MDP group, methotrexate group were notably higher than those of the control group(P＜0.01).The levels of control group was notably higher than that of the ~(99)Tc-MDP group(P＜0.05).There was not significant difference in all groups on the levels of TIMP-1 mRNA(P＞0.05).Conclusions ~(99)Tc-MDP can notably relieve the arthritis symdrome and retard the catilage damage and bone erosion of CIA in rats,and could significantly decrease the MMP-3 mRNA in the synovium.Which may be one of the therapeutic mechanism.~(99)Tc-MDP is better than methotrexate in retarding catilage and bone erosion and decreasing MMP-3 mRNA in CIA rats in a 3-week therapeutic intervention.

Objective To examine the expression of toll-like receptor 2(TLR2)in peripheral blood monocytes and explore its association with disease stages and clinical manifestations and to explore the patho- genesis of rheumatoid arthritis(RA).Methods The expression of toll-like receptor 2 in peripheral blood monocytes from 47 RA patientis(27 in active stage and 20 in stable stage)and 18 normal individuals were de- tected by flowcytometry and RT-PCR.Results The expression of toll-like receptor 2 in peripheral blood monocytes in patients with active disease was significantly increased compared to non-active patients and nor- mal individuals,The expression was found to correlate with the Disease Active Score(DAS),serum C-reactive protein(CRP)level and the erythrocyte sedimentation rate(ESR),but not correlate with rheumatoid factor (RF)and the anti-cyclic citrullinated peptide(CCP)antibody.Conclusion The expression of toll-like recep- tor 2 in peripheral blood monocytes of patients with active RA is significantly increased.And the expression is correlated with disease activity index.The innate immune system is activated in patients with active disease. And the increased expression may promote the activities of monocytes.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by the production of autoantibodies to a broad range of self-antigens. Profiling the autoantibody repertoire using array-based technology has emerged as a powerful tool for the identification of biomarkers in SLE and other autoimmune diseases. Proteomic microarray has the capacity to hold large number of self-antigens on a solid surface and serve as a high-throughput screening method for the determination of autoantibody specificities. The autoantigen arrays carrying a wide variety of self-antigens, such as cell nuclear components (nucleic acids and associated proteins), cytoplas-mic proteins, phospholipid proteins, cell matrix proteins, mucosal/secreted proteins, glomeruli, and other tissue-specific proteins, have been used for screening of autoantibody specificities associated with different manifestations of SLE. Arrays containing synthetic peptides and molecular modified proteins are also being utilized for identification of autoantibodies targeting to special antigenic epi-topes. Different isotypes of autoantibodies, including IgG, IgM, IgA, and IgE, as well as other Ig subtypes, can be detected simultaneously with multi-color labeled secondary antibodies. Serum and plasma are the most common biologic materials for autoantibody detection, but other body fluids such as cerebrospinal fluid, synovial fluid, and saliva can also be a source of autoantibody detection.

OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.
