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.

To analyze the compatibility regularity of compound traditional Chinese medicine (TCM) patents for treating dyslipidemia, and provide basis for the clinical development and research of new TCM for treating dyslipidemia. Totally 243 compound traditional Chinese medicine patents for treating dyslipidemia were collected from the national patent database from September 1985 to March 2014 and analyzed by using drug frequency, association rules, complex network and entropy method of Traditional Chinese Medicine Inheritance System (V1.1). The commonest single medicine in the treatment of dyslipidemia is Crataegi Fructus 109 (44.86%). The commonest pair medicine is Crataegi Fructus-Salviae Miltiorrhizae Radix et Rhizoma 53 (21.81%). The commonest corner drug is Crataegi Fructus-Cassiae Semen-Polygoni Multiflori Radix 25 (10.29%). The common prescriptions on basis of association rules are Prunellae Spica-->Salviae Miltiorrhizae Radix et Rhizoma (0.833), Rhei Radix et Rhizoma, Alismatis Rhizoma-->Polygoni Multiflori Radix (1.00), Salviae Miltiorrhizae Radix et Rhizoma, Cassiae Semen, Alismatis Rhizoma-->Polygoni Multiflori Radix (0.929). The core drugs based on complex networks are Salviae Miltiorrhizae Radix et Rhizoma and Crataegi Fructus. The new prescriptions extracted by entropy method are Atractylodis Macrocephalae Rhizoma-Glycyrrhizae Radix et Rhizoma-Platycladi Semen-Stephaniae Tetrandrae Radix; Citri Reticulatae Pericarpium-Poria-Coicis Semen-Pinelliae Rhizoma.

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.

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.
