Reconstructing the three-dimensional finite element model of compression fracture of T_(12) based on the 210-layer consecutive CT DICOM format images from one patient of compression fracture of T_(12) to simulate the hyperextending. Bound the lower of T_(12), a vertical traction at the top of T_(11)and a 3.0 cm-displacement toward the vertebra by three steps at the top of spinous process of T_(11), T_(12) and L_1 was provided. The procedure began computing to reed the results about dynamic biomechanical characteristics of anterior longitudinal ligament. A realistic appearance and full biomechanical properties 3D finite element model of thoracolumbar spine compression fracture was established. The anterior longitudinal ligament was changed from relaxation to tension after hyperextending. The stresses of anterior longitudinal ligament were different when the hyperextending fulcrum was different. The treatment effect of thoracalumbar spine compression fracture by hyperextending is exact. The anterior longitudinal ligament plays an important role in the treatment. Finite element analysis of mechanism of traditional practices has many advantages, such as reliable experimental results, direct displaying results, saving resources and accurate simulation.

The county health service planning is a very important link in county health reform, the planning process involves many professional problems, such as the setting of total bed number and proportional allocation. To solve these problems, it is needed to find a feasible method. Methods:Using operational research theory and method of linear programming to estimate whether the resource amount could satisfy the needs, and further explore the problem of the health resources in county-township-village. Results:(1) Operational research method could be used to judge whether the total bed amount and rate in county and township are suitable;(2) but linear programming to allocate capital budget model still exist some defects. The blind expansion and the pursuit of institution beds scale expansion are the phenomenon at present stage, the linear programming method could effectively help to determine whether these resources is really insufficient or excess. The method could be expanded to urban areas so as to supervision whether health resources are over expanded.

Objective To study the roles of protein kinase C (PKC) in the signal transduction pathway of LPS induced nuclear transcription factor (NF) ?B activation of alveolar macrophages(AMs). Methods NF ?B level in nuclear protein extraction of AMs was detected by sandwich ELISA. Intranuclear translocation of NF ?B was observed by immunocytochemical staining. Results LPS could induce NF ?B activation of AMs in time and dose dependent manners. Immunohistochemical staining revealed intranuclear translocation following LPS induction. Specific calphostin C (Cal C) and pyrrolidine dithiocarbamate (PDTC) could inhibit LPS induced NF ?B activation. Conclusion PKC, as a up stream messenger, is involved in the signal transduction pathway of LPS induced NF ?B activation.

AIM: To observe the effect of nonpenetrating trabeculectomy with implantation of amniotic membrane on the treatment of open-angle glaucoma.METHODS: Sixty-six cases (87 eyes) were randomly paired into 3 groups, treated with nonpenetrating trabeculectomy with implantation of amniotic membrane (22 cases, 29 eyes),compound trabeculectomy (22 cases, 29 eyes) and nonpenetrating trabeculectomy with implantation of SKGel (22 cases, 29 eyes), respectively.RESULTS: Compared with the other 2 groups, the group of nonpenetrating trabeculectomy with implantation of amniotic membrane got a better postoperative visual acuity (P＜0.01),satisfactively-controlled intraocular pressure (IOP) (P＜0.01)and fewer complications (P＜0.01).CONCLUSION: Nonpenetrating trabeculectomy with implantation of amniotic membrane is an effective method for the treatment of open-angle glaucoma.

Pharmacokinetic-pharmacodynamic(PK/PD)modeling,as an available tool accounting for the interrelated dynamic connection between the dosage and efficiency of drugs,plays an important role in the field of studying the mechanism and optimizing the clinical administration of traditional Chinese medicine(TCM).Based on the general illustration on the foregoing application of PK/PD modeling,the present work investigates the involving challenges in the field,such as the selection of the target chemical composition and effect mark.In accordance with the unique properties of TCM,further,the related suggestions,mainly focusing on determining the substances based on the effect and establishing the multi-index appraise system,are put forward as reference for the following research work.

Barrett's esophagus is known the only precancerous lesions of esophageal adenocarcinoma.Besides conventional endoscopy and pathologic biopsy,drugs and surgical treatment of the Barrett's esophagus,in recent years,some new endoscopic diagnosis and treatment technology were obtained.The progress of endoscopic diagnosis and therapy technique in Barrett's esophagus are reviewed in this paper.

AIM: Studies reveal that, cytokines play an important role in the process of various inflammatory reaction, wound repair and cell mutation, also, cytokines are expected to be a novel indicator of ratiocinating wound time. This study was designed to explore the changes in gene expression of interlukin-1? (IL-1?) and interlukin-1? (IL-1?) during the skin wound healing process in mice at different phases. METHODS: The experiment was carried out in the laboratory of Forensic Medicine Department of China Criminal Police University from March 2006 to December 2007. ①Thirty-five BALB/c inbred male white mice of cleaning grade, aged 25-27 g, were used in this study. ②Skin wound model was induced by injuries in the area of 1.0 cm away from two sides of spinal column, without affection on muscles. Three pairs of injuries were established in each mouse. Five animals were decapitated under anesthesia at 0, 3, 6, 12 hours and 1, 3, 6 days, respectively, whereas those at 0 hour were taken as controls. ③The white blood cells at different phases were observed under microscope after immunochemical staining. Real-time quantitative polymerase chain reaction method was applied to detect gene expression of IL-1? and IL-1?. RESULTS: Thirty-five BALB-c inbred male white mice were all involved in the result analysis. ①Skin wound was weakly positive during 0-5 hours after injury; the positive reaction was attenuated during 6-24 hours, and positive cells increased, of which macrophages were dominant. Infiltration of massive leucocyte neutrophils and a small quantity of mononuclear cells were detectable at 1 day; mononuclear cells increased during 2-4 days, and reached a peak at 3 days. In control group, the epidermis, folliculus pili, glandulae sebaceae and coil gland were all weakly positive. ②IL-1? and IL-1? were expressed at early phase after injury, and two expressing peaks were found at 6 and 72 hours, then decreased to normalized levels at 6 days after injury. CONCLUSION: Genet expression of IL-1? and IL-1? in damaged tissues has a regularity with wound time, and can be used for reference to estimate early injury age in forensic cases.
