With the understanding of anti?tumor angiopoiesis, researchers take VEGF and its receptors as targets, continuously exploring the new drug. We summarized the biological characteristics of VEGF, vascular?targeted therapy and the clinical application of drugs.

Using Low Shear-30 rheometer, we studied apparent viscosities at high (51.2-128.5s~(-1)), moderate (11.02-37.6s~(-1)), and Low (0.376-8.11s~(-1)) shear rate, viscoelastic properties of whole blood and hemodynamic parameters in 10 patients with acute myocardiac infarction(AMI), comparing with 10 patients with angina pectoris (AP) and 11 normal subjects(NS). It was demostrated that the apparent viscosities of whole blood at different shear rates mentionned above and viscoelastic properties of whole blood (the dynamic modulus G′, the loss modulus G″, "the viscous ?′ and the elastic component ?″ of complex viscosity) increased distinctly and parameters of cardiac function (EF, CO, LVET, PEP/LVET, HI, SV and CI) were abnormal obviously in AMI, in comparing with AP and NS (P

Relationship between hemorheology and blood gas analysis was studied in 37aged patients with chronic cor pulmonale, including 17 instable and 20 stable. Apparentviscosity (?a) of shear rate of 230.4 (?a(H)) and 5.76/s (?a(L)), TK values, redcell aggregation index(RAI) and PaCO_2 in instable chronic cor pulmonale (AG) were muchhigher than that of stable. patients (BG). Oxygen delivery index (OD) and PaO_2 in AGwere lower than in BG. ?a (H) was negatively correlated with OD and pH (r=-0.58,-0.40, P

BACKGROUND:The existing bone grafting apparatus are al long tubular-shape, antegrade bone grafting; however, the bone grains within the tube were difficult to put through, along with large bone loss. OBJECTIVE:To design a new concept of minimaly invasive bone grafting apparatus, so as to achieve the minimaly invasive bone grafting in vertebral body and intervertebral space. METHODS: On Solidworks 2012 software platform, the 3D three-dimensional solid modeling technology was employed to design a new concept of gun-shape bone grafting device with the characteristics of headend reversely placing at the grafting position and antegrade pushout, against the problems such as antegrade bone grafting, long bone grafting path and difficulty in bone grafting existing in precious percutaneous or/and transpedicular bone graft apparatus. The virtual assembly and simulative bone grafting surgery were performed with the bone grafting apparatus for observation of the instrument matching degree and grafting surgical procedures. RESULTS AND CONCLUSION: A set of minimaly invasive gun-shape bone grafting apparatus was successfuly designed; its length was 20 cm in total; the length of the front semi-closed bone tube was 2.5 cm. There are two kinds of diameter specifications: inner diameter of 3.5 mm/outer diameter of 4 mm, and inner diameter of 5 mm/outer diameter of 6 mm. Virtual assembly revealed that the grafting apparatus were wel matched. Stimulative surgery displayed that the bone grain loading and launch were simple. The gun-shape bone grafting device is reasonable in design, avoiding pushing too long distance, bone pushing difficulties, bone loss and other problems in previous tubular bone grafting apparatus. Percutaneous, endoscopic vertebrae or intervertebral space minimaly invasive bone grafting can be performed with this apparatus.

BACKGROUND: The application of polymerized 2-hydroxyethyl methacryate (PHEMA) in many organs of living body shows good biocompatibility.OBJECTIVE: To observe the biocompatibility and fibrovascular condition of methl-methacrylate (MMA) modified PHEMA hydrogel orbital implant.DESIGN: Single sample observation.SETTING: Department of Ophthalmology, the General Hospital of Chinese PLA; Institute of Polymer Science,Department of Chemical Engineering, Tinghua university.MATERIALS: Twenty-five New Zealand rabbits of either gender and clean grade, weighing 2.0 to 2.5 kg, were provided by the Animal Experimental Center, General Hospital of Chinese PLA. The animals were observed at postoperative 2, 4,8, 12 and 24 weeks, 5 at each time point. The experiment was permitted by ethics committee. MMA modified PHEMA hydrogel orbital implant was provided by Institute of Polymer Research, Department of Chemical Engineering, Tinghua University. The experiment was permitted by ethics committee.METHODS: This experiment was carried out in the laboratory of Department of Ophthalmology, the General Hospital of Chinese PLA from March to October 2003. The right eye served as operation eye. When the rabbits were anesthetized,their eyelids were open with eyelid retractor. Bulbar conjunctiva was open along the edge of limbus of cornea for isolating fascia. Oculorotatory muscle was isolated and pre-set suture line was made, then muscle was cut off. When optical nerve was cut off, eyeball was completely excised. A MMA modified PHEMA hydrogel orbital implant with the diameter of 14 mm was implanted into the fossa orbitalis of rabbits. Single photon emission computed tomography (SPECT) was performed at postoperative 2, 4, 8, 12 and 24 weeks. The hydrogel orbital implant was taken out at postoperative 2, 4, 8,12 and 24 weeks for light microscope, immunohistochemical and electron microscope examinations.MAIN OUTCOME MEASURES: Vascularization of hydrogel orbital implant was observed in vivo by isotope tracing observation at different time points. Vascularization of hydrogel orbital implant was observed ex vivo by light microscope,immunohistochemical and electron microscope observations.RESULTS: All 25 New Zealand rabbits were involved in the final analysis. ①SPECT examination showed that isotope increased around the implants at week 2, and extended gradually at weeks 4 and 8. The radiotracer accumulated evenly in the implants from surrounding to the center at week 12. ②Light microscopic examination of the prostheses revealed fiber vessels grew from the surrounding to the center. At week 2,fibrovascular tissue grew in the hole of implant. Long or round cells with deeply dyed nucleuses were found in the hole, being fibroblasts. The vascular structure in the hole of the implant was clear, and vascular wall and blood cells were found. The inflammatory cells were mainly neutrophils and lymphocytes, and occasionally large macrophages. ③Scanning electron microscope showed that fibrovascular tissue grew in the hole of the implant, and was dense and intercrossed at week 12. ④ Conjunctiva split appeared postoperatively in 1 of 25 cases, and healed well after two times of operation. Conjunctival congestion lessened and conjunctiva healed within postoperative 7 days in the remaining 24 animals.CONCLUSION: MMA modified PHEMA hydrogel orbital implant has good histocompatibility and fast vascularization process, and is easy to be operated with fewer complications. So, it is a safe and practicable new type orbital implant.

Objective To explore the complications of augmentation mammoplasty by polyacrylamide hydrogel (PAHG) injection and their management.Methods Preoperatively,174 patients underwent breast ultrasound image,and some patients received magnetic resonance imaging (MRI) to ascertain the distribution of injected PAHG.We used the periareolar incision and dissection extended to the subcutaneous tissue,mammary gland,and subgland space.We were able to suck most of the gel by the negative pressure machine and remove the abnormal breast tissue.The secondary breast deformity was repaired with subpectoral placement of silicone mammary implants (48 cases immediately,39 cases secondarily after 3-6 months) according to the individual situation.Results Following-up for 3 to 6 months,most of their symptoms were relieved after removal of the polyacrylamide hydrogel.In the patients who were performed with the implants augmentation mammoplasty,77 cases gained satisfactory results on the shape and texture of the breast (44.3％),and 10 cases were not satisfied with texture of the breast (5.7％).79 cases appeared breast atrophy or flat chest (45.4％).The severe breast deformities occurred in 8 cases (4.6％).Conclusions PAHG should be removed with surgical operation as soon as possible.The open operative technique via periareolar incisions may be a better method for the patients.The breast reconstruction is performed with implants prosthesis for those who are suitable and willing after removal of PAHG.

BACKGROUND:The form and structure of antigen-extracted xenogeneic cancel ous bone through series of physical and chemical treatment are similar to human tissue. OBJECTIVE:To detect the biocompatibility of antigen-extracted xenogeneic cancel ous bone matrix prepared by three different ways. METHODS:The antigen-extracted xenogeneic cancel ous bone scaffold materials which were prepared through physical, chemical and physical-chemical combined methods and hydroxy apatite biological ceramic materials were implanted into the dorsum subcutaneous tissue. Histological observation was done at 4, 8 and 12 weeks after surgery. The antigen-extracted xenogeneic cancel ous bone scaffold materials which were prepared through physical, chemical and physical-chemical combined methods respectively was used to culture sheep bone marrow mesenchymal stem cells for 7 days. Cel adhesion, growth, proliferation and stroma secretion were observed. RESULTS AND CONCLUSION:At 4 weeks after surgery, a strong inflammatory reaction was detected around materials in four groups. At 12 weeks, the xenogeneic bone materials prepared through physical and physical-chemical combined methods and hydroxy apatite biological ceramic materials internal pore and surrounding tissue inflammation disappeared basical y, with the presence of thimbleful inflammation cells. The material degradation was more than at 8 weeks. The xenogeneic bone materials prepared through chemical methods material internal pore and surrounding tissue inflammation stil existed, suggesting that the xenogeneic bone materials prepared through physical and physical-chemical combined methods exhibited good histocompatibility. A smal amount of orderly osteoblasts existed around hydroxy apatite biological ceramic materials and physical-chemical prepared materials, with a smal amount of bone. These suggested that there was a tendency for ectopic bone formation. The xenogeneic cancel ous bone materials prepared through physical or physical-chemical combined methods have better cytocompatibility. However, scaffold materials prepared through chemical method have poor cytocompatibility and they are not qualified for the safety standards of biological materials.
