BACKGROUND:Total knee arthroplasty for knee osteoarthritis accompanied with extra-articular deformity is stil chal enging. An individual replacement plan should be designed to obtain good mechanical axis and to recover suitable soft-tissue balance. OBJECTIVE:To observe the safety and feasibility of individual y designed one-stage total knee arthroplasty for knee osteoarthritis combined with ipsilateral femoral extra-articular deformity. METHODS:A total of eight patients with knee osteoarthritis combined with ipsilateral femoral extra-articular deformity were enrol ed in this study. According to preoperative plan, five patients underwent intra-articular compensatory osteotomy, and the remaining three received extra-articular corrective osteotomy. Multi-planar deformities as wel as soft-tissue conditions were recorded. Main outcome measures included the hospital for special surgery score, Western Ontario and McMaster Universities Arthritis Index score and alignments deviation. RESULTS AND CONCLUSION:The patients were averagely fol owed up for 29 months. The hospital for special surgery score changed from preoperative 32.5 points to postoperative 87.5 points. The Western Ontario and McMaster Universities Arthritis Index score was increased from preoperative 37.1 points to postoperative 88.8 points (P<0.05). Mean mechanical axis deviation (either varus or valgus) changed from preoperative 17.1° to postoperative 1.4° (P<0.05). Al cases with extra-articular corrective osteotomy healed within 3 months, and none had postoperative infection, loosening or venous thromboembolic events. One patient was with 5° residual knee anti-sheets. Results verified that one-stage total knee arthroplasty procedures are effective in the treatment of knee osteoarthritis accompanied with ipsilateral femoral extra-articular deformity in accordance with individual preoperative plan.

Objective To explore the typing,precaution and treatment of the bone cement leakage caused by percutaneous vertebroplasty(PVP).Methods PVP was performed in 38 cases(11 men and 27 women) with vertebral angioma and vertebral body compression fracture with osteoporosis chosen from November 2002.Results All the patients were followed up for 8 to 16 months and the effects were evaluated by the standards carried out by World Health Organization(WHO).The rate of complete response(CR) plus partial response(PR) was 100 percent.The patients with bone cement leakage by PVP were divided into 3 groups which underwent different remedial methods respectively.Conclusion The bone cement leakage could be prevented through the preoperative preparation,choosing the anaesthesia and scouting the whole operation.The patients with TypeⅠ,Ⅱ and Ⅲ_a needn't treatment,but those with type Ⅲ_b must accept open-operation.Vertebral eggshell technology with open vertebroplasty was effective on the treatment of the bone cement leakage with type Ⅲ_b caused by PVP.

BACKGROUND:Now the filling material which is used for the treatment of osteoporotic compression fractures is mainly polymethacrylic acid (PMMA),but the PMMA as a permanent foreign body cannot promote bone regeneration,and has a downward extension of the possibility of mechanical properties with time prolonging,so a new type of filling material used to substitute PMMA is looking.OBJECTIVE:To investigate the effect and image characteristics of different filling materials on percutaneous vertebroplasty performing on a goat model of osteoporotic compression fracture.METHODS:Three vertebral fracture models were established on osteoporosis goats by using an appropriate mechanical stress.Under the G-arm X-ray machine,the fractured vertebrae was performed with percutaneous vertebroplasty and then filled with polymethyl methacrylate (PMMA),self-setting calcium phosphate cement (CPC) and recombinant human bone morphogenetic protein-2(rhBMP-2)/self-calcium phosphate cement.RESULTS AND CONCLUSION:① A total of 36 vertebral bodies of 12 goats were successfully performed with percutaneous vertebroplasty,and there was no significant difference in filling quantity among three materials (3.5±1.8) mL (P>0.05).Bolus resistance of PMMA was strong,but operative time was short,and the image was great;the bolus resistance of self-CPC and rhBMP-2/self-CPC was weak,operative time was long,but there was no leakage placeholde.②CT scanning results on the 2~(nd) day after surgery demonstrated that the three materials were disorderly distributed in the vertebral body,showing high-density patching shaping.Six out of 36 vertebral bodies were leakage,which was induced by PMMA (n=4),self-CPC (n=1),and rhBMP-2/self-CPC (n=1).③ Scanning electron microscope indicated that all materials in the PMMA group were not able to closely bind with host bone,but self-CPC and rhBMP-2/self-CPC were able to closely bind with host bone.The results suggested that rhBMP-2/self-CPC is characterized by long-term operation,short time of bone substitute,and stabilization of reconstructed spine.

Objective:To clarify the mechanism of crisis serum' mediated gametocyte infectivity to the mosquito vector Methods:Observing the effects of mouse serum , which was obtained 5 days after P yoelii infection (D5 serum) on gametocyte infectivity by IFA and mosquito live feeds, and the production of IFN ??TNF ??IL 4 and NO - 2 in the hosts in vivo and in vitro by ELISA and Griess reaction And to investigate the ability of malaria parasitized red blood cell extract (PRBC extract) to induce NO Results:The development of the gametocytes from mice 5 days postinfection into ookinetes were completely inhibited D5 serum was not immediate to inhibit gametocyte development, which was injected intravenously into the mice 3 days after P yoelii infection But 4 h later after injection D5 serum stimulated the increasing IFN ? and NO production and inhibited gametocyte infectivity Moreover, PRBC extract showed the ability to induce NO Conclusion:Infected host serum blocks transmission of P yoelii via a nitric oxide dependent mechanism

Objective:To investigate the expression of antigens in Plasmodium yoelii sexual stage and transmission blocking effects of monoclonal antibodies(McAbs).Methods:Observing the effects of anti Pys25 McAb4 and anti Pys21 McAb10 on developmental course of parasites in mosquitoes by direct mosquito feeds on passively immunized P.yoelii infected mice and the expression of Pys21 and Pys25 from gametocytes to ookinetes in indicated culture times by IFA and Western blotting.Results:The transmission blocking activity of the anti Pys25 McAb4 was complete and more potent than that of the anti Pys21 McAb10.Both Pys25 and Pys21 were presented in whole developmental course from gametocytes to ookinetes.Furthermore,the expression of Pys25 appeared to be earlier than that of Pys21 on zygote surfact.Conclusion:Pys25 and Pys21 are target antigens of transmission blocking immunity and that anti Pys25 McAb4 has more significantly transmission blocking activity is related with the early stage expression of Pys25 on zygote surface.

Cisplatin, an efficient anticancer agent, can trigger multiple apoptotic pathways in cancer cell. However, the signal transduction pathways in response to cisplatin-based chemotherapy are complicated, and the mechanism is not fully understood. Using fluorescence resonance energy transfer (FRET) technique, the molecular mechanism of cisplatin-induced apoptosis in living human lung adenocarcinoma cells (ASTC-a-1) were investigated. After cisplatin treatment, the recombinant pFRET-Bid and pSCAT-3 probes were used to determine the kinetics of Bid cleavage and Caspase-3 activation, respectively. The fluorescence probes Bid-CFP and DsRed-Mit were also used to detect the spatial and temporal changes of Bid in real-time in sub-cell level. The results showed that a cleavage of the Bid-FRET probe occurring at about 4～5 h after treated with 20 ?mol/L cisplatin. Cleavage of the Bid-FRET probe coincided with a translocation of tBid from the cytosolic to the mitochondria, and the translocation lasted about 1.5 h. At the anaphase of cell apoptosis, Caspase-3 was activated obviously as detected by FRET and Western blotting techniques. Using real-time single-cell analysis, it was observed the kinetics of Bid and Caspase-3 activation for the first time in living cells during cisplatin-induced apoptosis.
