Objective To design and research of clinical medicine training visual simulation system based on Multigen/Vega. Methods Using MultiGen Creator modeling human organs, the three -dimensional objects were described by geometry, hierarchical structure and attributes description, and were in OpenFligh format storage. The virtual training situation required special effects can be generated by Vega on the model-driven. Results The simulation is divided into a virtual operating system and virtual scenes of real-time display. Conclusion The system is economic, safe, controllable, and is of great significance for improving skills of training in medical staff.

OBJECTIVE: To study the endosomatic pharmacokinetics and bioequiavailability of kushenin tablets in health adults. METHODS: The blood concentrations of the blood samples taken from 22 healthy volunteers were determined by HPLC-MS after a single oral 0.3g kushenin (either tablet or capsule) dose and pretreatment with the internal standard (cimetidine) with m/z 265 (kushenin) taken as the detection ions and m/z 253 as the internal standard. RESULTS: The main pharmacokinetic parameters of the tablet and capsule of kushenin were as follows: t1/2 stood at (2.30?1.09)h and (1.90?0.58) h, respectively; tmax stood at (1.86?0.74)h and (1.68?0.55) h, respectively; Cmax stood at (525.09?208.94)ng/ml and (530.32?202.04) ng/ml, respectively; AUC0～11 stood at(2 048.5?749.4)(ng?h)/ml and (2 042.0?743.0)(ng?h)/ml, respectively;AUC0～∞ stood at(2 163.2?783.1)(ng?h)/ml and (2 136.4?792.1)(ng?h)/ml, respectively. The relative bioavailability of the kushenin tablet stood at (101.06?9.41) %. CONCLUSION:The tablet and capsule of kushenin were bioequiva_lent.

Diffuse large B-cell lymphoma (DLBCL) is the most common malignant lymphoma in China,which mostly starting from the lymph nodes.The studies find that the expression of NLRC5,member of nucleotide-binding oligomerization domain-like receptor (NLR) family,is evident in the lymphoid cells,which is likely to be an important basis for lymphocyte tumorigenesis.NLRC5 can block the nuclear factor-κB (NF-κB),a core component of signal transduction pathway,and affect the development of tumor.While continuing activation of NF-κB is a necessary condition for DLBCL cell survival.Therefore,NLRC5 is likely to inhibit excessive inflammation,thereby inhibiting the function of DLBCL,which promises to be a new target for immunotherapy treatment of DLBCL.

Objective To observe the expression of pancreatic K_(ATP) channels (Kir6.2/SUR1) in rats with chronic pancreatitis and explore the intervention of nateglinide on the changes.Methods Wistar rats were induced to suffer from chronic pancreatitis and then randomized into model group, nateglinide group and control group.Then OGTT of them were observed.RT-PCR was used to detect the expression of Kir6.2 and SUR1 mRNA, and western blot to detect the expression of Kir6.2 and SUR1 proteins.Results Model rats displayed impaired glucose tolerance (IGT).The expression of Kir6.2 and SUR1 in model group decreased significantly(P＜0.05), and nateglinide displayed up-reg-ulation to the expression in some degree.Conclusion The expression of pancreatic K_(ATP) channels in rats with chronic pancreatitis diminished, which might be the important mechanism of the development of pancreatogenic diabetes.Nateglinide can up-regulate the expression in some degree, which indicates that it may have latent effect of ameliorating the prognosis of patients with chronic pancreatitis.

Objective To evaluat physical exercise's effct on left ventricle diastolic function.Methods 12 college athletes and 12 students' transmital flow volume in peace state were measured and analysed. Results College athletes' MV VTI is bigger, MEAD GRAD and A are smaller.Conclusion Physical exercise can improve the brimming and unhindering abilities of left ventricle and increase the area of mitral valve.

120 casea of bronchogenic carcinoma treated 286 times by BAI revealed several types of bronchial arterial variations in 12 cases and multiple feeding arteries in 56 cases by way of selective Bronchial arteriography.The article emphasizes the significance of the existence bronchial arterial anomalies and multiple feeding arteries in BAI.And also we ex plored the selective catheterization technique in the bronchial arteriography.

Objective To study the effect of a distal protection device (Pereusurge GuardWire: GW) on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention. Method Acute STEMI patients treated with primary PCI were eligible to be studied. Inclusion criteria were: (1) within 12 hours from the onset of chest pain;(2) culprit leision with diameter stenosis≥70% and TIMI flow grade≤2. Exclusion criteria were:(1) patients undergoing thrombolytic therapy before PCI; (2) a culprit lesion in the left main coronary artery;(3)reference vessel diameter

Refresher training is the most important ways of continuing medical education. This paper introduces the training situation of refresher doctors of Children's Hospital of Fudan University by distribution of professional title, education departments and experience in training. We have sum-marized the management mode of refresher doctors from such aspects as the entrance management, pre-job training, authorization to work, strengthening clinical practice to expand knowledge, clinical research training, self-learning ability improvement, strengthening emotional communication, humani-zation management, emotional bonds establishment and creation of a follow-up development environment.
