OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

A three-dimensional (3D) graphic model of a single-chain Fv (scFv) which was derived from an anti-human placental acidic isoferritin (PAF) monoclonal antibody (Mab) was constructed by a homologous protein-predicting computer algorithm on Silicon graphic computer station.The structure, surface static electricity and hydrophobicity of scFv were investigated. Computer graphic modelling indicated that all regions of scFv including the linker, variable regions of the heavy (VH) and light (VL) chains were suitable. The VH region and the VL region were involved in composing the "hydrophobic pocket". The linker was drifted away VH and VL regions. The complementarity determining regions (CDRs) of VH and VL regions surrounded the "hydrophobic pocket". This study provides a theory basis for improving antibody affinity, investigating antibody structure and analyzing the functions of VH and VL regions in antibody activity.

To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated. Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all <0.001).In the ultra-early stage after surgery,HCR was significantly higher in the KAES group(<0.001),whereas in the early and sub-early stage,HCR showed no significant differences(all >0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all >0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all >0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(=0.413). Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

OBJECTIVETo evaluate in vivo pharmacokinetics of Ophiopogonis Radix polysaccharide MDG-1 oily suspension injection prepared with different prescriptions in rats, and explore the feasibility of the long-acting drug delivery of MDG-1 Injection by using the oily suspension drug release system.

METHODMDG-1 microparticles were prepared by the anti-solvent precipitation method. Their size and size distribution were characterized. Castor oil with a high viscosity or aluminum stearate were added into soybean oil with a low viscosity, in order to prepare oily media with different viscosities, detect their rheological properties and screen out superior prescriptions for in vivo evaluation.

RESULTThe average size of microparticles was 21.81 microm, and the span between them was 2.63. The in vivo evaluation was conducted for prescriptions of mixed oil (soybean oil/castor oil, 2: 3) and soybean oils gelled by 2% and 4% aluminium stearate. Among them, the prescription of soybean gelled by 4% aluminium stearate could significantly reduce C(max) and prolong the apparent t1/2, with the MDG-1 release time of several days.

CONCLUSIONIt is feasible to achieve the long-acting MDG-1 drug delivery by using oily media with a high viscosity.

The ideal treatment and recovery of osteoarticular injury remain to be resolved. Small intestinal submucosa (SIS), a naturally-occurring decellularized extracellular matrix, has been recognized as an ideal scaffold for tissue engineering and widely used in repairing various tissues and organs. Nowadays its application has also been gradually increased in the field of orthopedics. We reviewed laboratorial studies and clinical trails about the application of SIS in bone and joint repair, aiming to evaluate its effects on the repair of bone, cartilage, meniscus, ligament and tendon. SIS has showed promising results in repairing bone, meniscus, ligament or tendon. However, additional studies will be required to further evaluate its effects on articular cartilage and tendon-bone healing. How to optimize SIS material,is also a focused problem concerned with making SIS a potential therapeutic option with high value for orthopedic tissue repair.

Objective:To investigate the possibility of using radioiodine labeled framework region(FR)antisense oligonucleotides(ASONs)as an imaging agent or antisense therapeutic radiopharmaceu-tical in lymphoma.Methods:A 18-mer partial phosphorothioate oligonucleotide sequence was synthe-sized and grafted in 5'with a tyramine group which was further radioiodinated.Radioiodination of the tyra-mine derivatized oligonucleotides was performed using the chloramine T method.(1)Normal CD-1 micewere injected via a tail vein with 148 kBq (125)~I-FR-ASON(2-3?g).Animals were sacrificed at the endof 1,2,4 and 24h,and tissue samples were studied.(2)Liposome-mediated 3.33 MBq (131)I-FR-ASON(7-9?g)were injected intralumorally into tumor-bearing BALB/c mice(6 weeks after innculation of10~7 Namalwa cells)meanwhile liposome-mediated (131)~I labeled sense oligonucleotides served as controls.Biodistribution was monitored by sequential scintigraphy and organ radioactivity measurement 24h afterinjection.Percentage of the injected dose per gram of tumor and tumor/non-tumor tissue ratios(T/NT)were calculated tot each group of mice and the difference between two groups was assessed.Results:The5′tyramine group allowed specific and stable radinlabeling of the ASON with radioiodine.The radioactivi-ty reached its peak 1h after injection,and then decreased rapidly in normal mice after intravenous ad-ministration of (125)~I-FR-ASON.The liver,stomach and intestine played an important role in biodistributionand radioactivity counts were low in bone,brain and blood.When (131)I-FR-ASON was injected intratumor-ally into mice grafted with Namalwa cell line,images showed the tracer accumulated in the tumor,Imme-diately after intratumoral administration,only the tumor was visible.Scintiscans performed at the end of 1and 2h showed elimination of the tracer from the tumor to the abdomen and at the end of 24h the tumorwas clearly seen.Percentage of the injected dose per gram of tumor and T/NT ratios for the sense group(control)were significantly lower than those of the antisense group.Conclusion:Radiolabeled Ig FRASON showed high specificity in V1 family B-cell lymphoma,which should be further investigated for nu-clear medicine imaging application and radionuclide antisense therapy.
