Reactivation of hepatitis B virus is a common complication of patients with malignant tumor chemotherapy, and gets more attention in clinicians. But the mechanism of reactivation of hepatitis B virus is not completely understood. There is not a unified definition and the prevention and cure of reactivation of HBV at home and abroad. In this paper, the relevant content of HBV reactivation in recent years is reviewed.

Ischemic stroke is a kind of common and frequently-occurring disease in clinic. It has high morbidity and high mortality and high morbidity characteristics. It was treated may also use a variety of Chinese and western medicine in the acute phase in the large general hospital in clinical practice. According to the "modularity theory" from biology, different patients using different drugs, and with combination of drugs for the treatment of this disease may have a variety of topological structure characteristics. This study proposed in the national 15 large general hospital electronic medical records of database, the complex network constructed by acute ischemic stroke disease using drugs, adopting to the complex network analysis and data mining methods to build for different ischemic stroke patients who are many of Chinese and western medicine group modules. These modules can be explained structure and function characteristics, and to explore the appropriate crowd and evaluate drug group module efficacy and safety in use in clinic. It provide direction to optimize the clinical treatment for ischemic stroke, provide new method for the research on combination, also provide the basis for drug combination of Chinese and western solution into the guide.

With the frequent culture communication between china and Japan, YanQi theory of TCM spread to Japan and exerted an influence on Japanese medicine. From the volume of"YunQi" in "The literature investigation of TCM", we can tell YunQi theory occupied a major position in the Japanese medical literatures which spread from china. The primary books of YunQi edited by Japanese scholars reveal Japanese doctors are apt to use this theory to promote their clinical practice. The accordant cognition of Chinese and Japanese scholars is that Japanese doctors accept the value of YunQi theory and beware of it's deficiency in clinic.

BACKGROUND: Microsurgical operation might fail due to trauma-induced hypercoagulability.OBJECTIVE: To observe the changes of polymerization of fibrin monomer after the treatment of trauma so as to explore an effective means for assisting the prediction of post-traumatic hypercoagulability and thrombosis.DESIGN: Case-control observation and self-control study.SETTING: Institute of Thrombus and Hemostasis, the Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.PARTICIPANTS: Totally 34 traumatic patients were included from those who were admitted to the Union Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology, between May 2001 and January 2002. There were 18 males and 16 females aged 8-65 years old. Another 96 healthy people, 50 males and 46 females aged 21-68 years old, who came for routine physical examination were enrolled as normal controls. The history of coagulation impairment, and general and coagulation-related diseases were excluded in all the subjects.METHODS: Polymerization of plasmic fibrin monomer was detected. Fibrinogen would transform into fibrin monomers and display polymerization induced by acutobin. The accompanied changes of the turbidity were dynamically monitored using spectrophotometer at 340 nm; the obtained electrical signals were then input into the computer for statistical analysis. Venous blood samples were collected from traumatic patients immediately after hospitalization and on the 3rd day after the treatment with clinical debridement, surgery, sutures, liquid supplement and administration of antibiotics to determine polymerization of fibrin monomer. MAIN OUTCOME MEASURES: ① The rate of polymerization of fibrin monomer (taken as the comprehensive predictor for the concentration and function of plasmic fibrinogens). ② Maximum absorbency (reflecting the amount of coagulable plasmic fibrinogen in blood specimen). ③ The ratio between the rate of polymerization of fibrin monomer and maximum ab sorbency (reflecting the polymerization of plasmic fibrinogen molecules). RESULTS: All participants completed the corresponding examinations and were brought into data analysis. ① In traumatic group, the rate of fibrin monomer polymerization, the content of fibrinogen, the ratio of polymerization rate to maximum absorbency were all significantly higher than those in normal control group [traumatic group: 0.87±0.31, (5.81±3.22) g/L,4.61±0.97; normal control group: 0.61±0.15, (3.36±1.02) g/L, 3.93±0.68,P ＜ 0.01]. ② At treatment of 3 days, although the rate of polymerization and the content of fibrinogen were found slightly declined, they were still higher than those in normal group [3.93±0.68, (4.21±1.93) g/L]; however,the ratio of polymerization rate to maximum absorbency did not change after treatment (4.68± 1.19).CONCLUSION: The content and function of fibrinogen would increase in traumatic patients. Traumatic patients display hypercoagulability characteristics and have thrombosis tendency. Determining the polymerization of fibrin monomer can be taken as an effective means for assisting the prediction of posttraumatic hypercoagulability and thrombosis.

OBJECTIVE: To evaluate the features and application of tissue engineered biomaterials in repairing femur defects, and to search an optimal femur substitution.METHODS: Papers published between January 1993 and October 2009 were searched using computer with key words of "tissue engineering, femur defect, mesenchymal stem cells, cytokines and materials" both in English and Chinese. Documents addressing biomaterials and tissue engineered bone in repairing femur defects were included. Repetitive research or Meta analysis was excluded. After that, 21 literatures were selected to discuss the features and application of tissue engineered biomaterials in repairing femur defects.RESULTS: Stem cells technology is obtaining seed cells from myeloid tissues, amplifying in vitro, combining with scaffold material, and in vitro constructing tissue engineered bones. The cultured cells could maintain osteoblast biological characteristics and fully fused with bone tissues at recipient sites, simultaneously, avoid immunological rejection. The combination of materials or modify the material surface could promote cells adhere to materials and increase the cellular biological activity. When transfecting seed cells to bone defect areas using certain carriers, the transplanted calls could form new bones and secret bone growth factor, induce determined osteogenic precursor cells differentiated into inducible ostegenic precursor cells, thereby, fasten the bone healing. The composite materials prepared by three-dimensional virtual surgical simulation and computer numerical control exhibited advantages of composite materials and histological anatomy conjunction, which had perfect appearance.CONCLUSION: Currently, there is no material can fully meet the requirement of bone tissue engineering. Thus, promoting adhesion between cells and materials, increasing cellular biological activity, and maintaining biological functions by combing materials or modifying material surface are the research focuses.
