Results Each pair of thread groups was taken full advantage by achieving twin-network. Conclusion By comparing the two types of transformation methods, a set of practical solution is explored of handy, mobility, non-destructive and reversible.

Objective To study the protective effects of choline on myocardial ischemia rat heart and its potential mecha -nisms .Methods Ischemia hypoxia environment was simulated with low value of pH (pH 6 .8) and lack of oxygen .Calcium currents were recorded by whole cell patch under the voltage clamp configuration .The alternations in[Ca2 + ]induced by KCl was detected by laser scanning confocal microscope in ventricular myocytes ,then disccuss the effects of choline on calcium and calcium store in cells . Results The normalized peak currents of ICa-L in ventricular myocytes were larger in pH 6 .8 group than those in pH 7 .4 group , which can be attenuated by choline .The(Ca2 + )i induced by KCl in ventricular myocytes were significantly increased in pH 6 .8 Ty-rode solution and its increasing can be suppressed by choline .4-DAMP can inhibit the suppressing effect of choline .Conclusion The possible mechanism of M 3 receptor involved in the protection of ischemic myocardium by inhibiting myocardial cells in ICa-L ,in-hibiting intracellular calcium overload .

BACKGROUND: Naked plasmid DNA cannot transfect cells effectively because of negative charge and the degradation of nuclease. Chitosan is a biodegradable natural cationic polysaccharide. It can provide effective protection against DNases and enhance transfection efficiency.OBJECTIVE: To prepare chitosan nanoparticles loaded with pcDNA3.1(-)/MAGE-3-HSP70 by complex coacervation method and to research its characteristics.DESIGN, TIME AND SETTING: A controlled experiment was performed at the Key Laboratory of Nano-biotechnology, National Ministry of Public Health of China from February to August 2009.MATERIALS: pcDNA3.1 (-)/MAGE-3-HSP70 was constructed at the Key Laboratory of Nano-biotechnology, National Ministry of Public Health of China. Chitosan, deacetylation degree > 90.0%, viscosity < 100 cps, batch number 060306, was obtained from Shanghai Bio Life Science & Technology Co., Ltd. B16 cells were presented by the Institute of Oncology, Central South University. METHODS: Chitosan nanoparticles loaded with pcDNA3.1(-)/MAGE-3-HSP70 were prepared by complex coacervation method. Then the naparticles were transfected into B16 cells, and the level of MAGE-3-HSP70 mRNA was tested using reverse transcription-polymerase chain reaction (RT-PCR) technology. The in vitro cytotoxicity of the nanoparticles was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl (MTT) assay.MAIN OUTCOME MEASURES: Particle diameter and Zeta potential were determined by ZetaSizer 1000HSA. Efficiency of the encapsulation was measured with a spectrophotometer. The combination manner was observed by gel retardation test. The ability to protect plasmid DNA from Dnase I degradation was evaluated by DNase Ⅰ protection test. RESULTS: The mean diameter of chitosan plasmid DNA nanoparticles was 223 nm, its zeta potential was 16 mV. The encapsulation efficiency of DNA was 92.3%. The transfection efficiency of chitosan plasmid DNA nanoparticles by B16 cells was about equivalent to that of the Lipofectamine 2000 reagent. Chitosan plasmid DNA nanoparticles were much less cytotoxlc when compared with Lipofectamine 2000-pDNA complexes.CONCLUSION: Chitosan plasmid DNA nanoparticle were nontoxic to cultured cells and plasmid DNA can be efficiently transferred into B16 cells by chitosan nanoparticles.

Objective To summarize the experience of nursing cooperation for immediate breast reconstruction with the latissimus dorsi myocutaneous flap. Methods Twenty breast cancer patients underwent modified radical surgery with intraoperative immediate application of the latissimus dorsi myocutaneous flap in combination with the same period breast prosthesis for breast reconstruction. The nursing measures included preoperative preparation and mental support, intraoperative active cooperation, position care, sustaining of body temperature and strict aseptic and disease-free technology. Results All the breast cancer patients lived through breast cancer modified radical immediate breast reconstruction. No flap necrosis occurred , neither did obvious complications. The operations were satisfactory. Conclusion The key to the breast reconstruction for the breast cancer patients exists in preoperative psychological nursing , intraoperative strict aseptic and disease-free technology , the proper operation position and the correct use of instruments and equipment.

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.

? AIM: To observe the efficacy and safety of the phacoemulsification combined with goniosynechialysis and the phacoemulsification combined with trabeculectomy for angle-closure glaucoma ( ACG ) with different closure conditions accompanied with cataract.?METHODS:A total of 65 patients (70 eyes) with primary ACG accompanied with cataract were selected from those admitted in our hospital and were given phacoemulsification with goniosynechialysis ( group A, 30 patients with 33 eyes ) and the phacoemulsification with trabeculectomy ( group B, 35 patients with 37 eyes ) according to the conditions of the closed anterior angle, respectively. The two groups of patients were observed for preoperative and postoperative intraocular pressure ( IOP ) , vision, anterior chamber depth, and complications, and were followed up for 6. 5mo (6-8mo) on average.?RESULTS: Mean postoperative IOP in either group A or group B at 1mo after operation was of statistically significant difference, compared with mean preoperative IOP (P<0. 05). Postoperative 1-week vision in each group was of statistically significant difference, compared with preoperative vision (P<0. 05). Postoperative 1-month mean anterior chamber depth in each group was of statistically significant difference, compared with preoperative anterior chamber depth (P<0. 05). There were no significant differences between the two groups on postoperative 1-month mean anterior chamber depth ( P>0. 05) and postoperative complications (P>0. 05).?CONCLUSION: Clinical doctors can choose appropriate treatment according to different conditions of the closed anterior angle in patients with primary angle- closure glaucoma.
