With the development of the cross-correlation technique in surgery, the transplantation and vi-cariousness have become more and more important in repair surgery and reconstructive surgery. A nice bio-material could replace the related tissue or organ of human body, support the homologous function of organ-ism,and accelerate the process of self recovery and autotherapy. This review is about the status of research and application of biomaterial in surgery.

A nice biomaterial,which could replace the correlated tissue or organic of human body,supports the homologous function of organism,and accelerates the process of self recovery and autotherapy in the same time.The application of biomaterial in clinic,not only have the chemical characters and function of vitodynamics to match,but also be with nice biocompatibility and practical safety.Some development of biomaterial and the biocompatibility of it in this paper was reviewed,and the application status in the cardiothoracic surgery in recent years.

Objective:To discuss the quality control method of injection pump and analyze the factors that affect the quality control of injection pump.Methods: Flow error and blocking alarm error were tested by the INFUTEST 2000E dual-channel infusion pump analyzer according to the national calibration specifications.Results: The syringe specifications, injection speed and injection solvent could influence the test for accuracy of injection pump. The lower injection speed set, the bigger flow test error was, while the smaller the blocking alarm test error was. On the other hand, the higher the injection speed set, the smaller the flow test error was and the bigger the blocking alarm test error was. Besides, the higher qualified rate of flow test was, the lower the qualified rate of blocking alarm test was.Conclusion: The quality control of injection pump should abide by the principle of controllable risk, and should not pursuit too much accuracy.

After the problems in digitalizing ancient books on traditional Chinese medicine were analyzed, the principles that should be followed in their digitalization were pointed out according to its theories and practice.The platform for digitalizing them was constructed with《Collective Notes to Canon of Materia Medica》as an example, and its design ideas, framework, development model and functional modules were described.

Objective To study the diagnostic value of spiral CT pulmonary angiography(SCTPA) for pulmonary embolism(PE).Methods SCTPA scans were performed in 25 patients with PE,the contrast-enhanced SCT scans of the pulmonary arteries were performed,MPR,MIP and SSD were performed simultaneously.Results The 29 SCTPA scans were performed in 25 patients, including the central type in 23 cases(92%) and the peripheral type in 2 cases(8%).The rates of the main,the sinistral and dextral,the middle lobular,the lobular and the lingular pulmonary artery displayed were 100%,the rates of the segmental pulmonary artery displayed were 97.77% and the rates of the subsegmental pulmonary artery displayed were 68.00%.The lobular and segmental pulmonary artery were mainly embolized,the rates of PE were between 46.58% and 75.00%.Conclusion SCTPA has great value in earlier and clear and definite diagnosis of PE.

ObjectiveTo explore the cytogenetic characteristics of multiple myeloma (MM) patients,to evaluate the effect of a long-term culture stimulated by cytokines on cytogenetic study of MM,and to investigate the clinical detection value of RB1 and P53 deletion in interphase plasma cells by using fluorescence in situ hybridization (FISH).MethodsKaryotype analysis was performed in 81 MM patients by using the short-term culture of bone marrow cell and G-banding technique.Among the 81 MM patients,28 patients used two culture methods:one was the short-term culture and the other was to culture cells for 6 days with recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) (40 μg/L) and IL-6 (10 μg/L).RB1 and P53 deletion were detected on interphase plasma cells by using FISH in 31 patients.ResultsAmong the 81 patients,75 had enough metaphases for analysis.Among the 75 patients,31 (41.3％)had clonal karyotypic abnormalities including 4 numeric abnormalities,11structural abnormalities and 16 both abnormalities.Among the 28 patients using two culture methods,the clonal karyotypic abnormalities were detected in 6 patients(25.0％ ) in the group of cultured for 24 hours,and 14 patients (51.9％) in 6-day culture group with a significant difference (P =0.026).RB1 deletion and P53 deletion were detected in 10 patients (32.3％ ) and 11 patients(35.5％ ),respectively,with both RB1 and P53 deletions be detected in 5 patients ( 16.1％ ).ConclusionsMore than half of the tested MM patients have both numeric and structural chromosome abnormalities.The karyotype analysis using banding technique is basic cytogenetic study.Extended culture in the presence of IL-6 and GM-CSF could improve the efficiency of cytogenetic analysis to MM.Interphase FISH is a sensitive method of clinical application significance to detect the gene deletion of MM.

BACKGROUND:A series of pathological changes were found in atlas, including atlas dislocation, atlanto-occipital junction instability and vertebral fractures. Atlantoaxial pedicle screw, nail and rod fixation or nail plate fixation is a novel repair method recently proposed, and has certain advantages. OBJECTIVE:To compare the repair effects of atlas pedicle screw on different types of atlas lesions. METHODS:A total of 42 fresh vertebrae were obtained from Department of Human Anatomy, Basic Medical School, Inner Mongolia Medical University. In accordance with bone thickness of sagittal vertebral artery groove bottom, vertebrae were divided into three types:type I (common type), type II (light variation), and type III (severe variation). Al samples were subjected to atlas pedicle screw fixation. RESULTS AND CONCLUSION:The screw pul out force in different bone densities of vertebrae was not the same. Vertebrae with great thickness and great bone density had big screw pul out force (P<0.05). However, the screw in different cortical bone of vertebrae had the same function. No compression on blood vessels or phenomenon affecting vertebral activity was visible. These results indicated that atlas pedicle screw implantation showed good safety, no side effects, did not affect the normal work and life of patients.
