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 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.

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 observe effect of Huoluojiangu capsule (HJC) on analgesic experiments. Methods The 3 kinds of analgesic experiments of whirling body, electric irritation and hot board were respectively adopted in mice. 60 mice were randomly divided into 6 groups in every analgesic experiment:A group(blank control), normal saline 0.25 mL/10 g. B group (positive control), diclofenac sodium 3.5 mg/kg;C group (positive control), pethidine 15 mg/kg, D,E and F group were respectively as low,mid and high dose of HJC groups (HJC 14, 21, 28 g/kg). Afterward, effects of HJC on ache induced by chemistry, electricity and heat were respectively observed at different time after pretreatments. Results Low, mid and high dose of HJC groups can all inhibit reaction of whirling body by chemical irritation. Compared with blank control group, low dose of group had evidently effect, P 0.05), but it had stronger analgesic effect than positive groups (B and C groups) at 180 min, P

Objective To study the effects and possible mechanism of Huoluo Jiangu Capsule (HJC) on adjuvant arthritis rats. Methods The arthritic model of rats induced by Freund’s complete adjuvant was used in experiment. The effect of HJC on swelling degree of feet, weight of thymuse and spleen of AA rats were observed. The serum activity of SOD, GSH-Px and content of NO, MDA were determined. Results HJC can relieve swelling degree of feet and weight of spleen of AA rats, increase serum SOD, GSH-Px and decrease serum NO, MDA of AA rats. Conclusion HJC has good effet of cleaning up the oxygen free radicals and anti-inflammatory.

Objective To study the characteristic of in-vivo nasal mucosa absorption of tetramethylpyrazine phosphate(TMPP) liposome in rats. Methods Nasal circulatory perfusion method in rats was used to study the effects of different circulatory rates and TMPP concentrations on nasal mucosa absorption of TMPP liposome. Nasal mucosa absorption rate constants of TMPP liposomes and TMPP solutions at the same concentration were also compared. Results The absorption rate constant of TMPP liposomes was increased with the increase of circulatory rates at the range of 1.2～2.4 mL/min and with the increase of TMPP concentrations at the range of 0.245～0.98 mg/mL. Both the absorption rate constant and absorbed amount of TMPP for TMPP liposomes were higher than those for TMPP solutions at the same concentration. Conclusion The nasal mucosa absorption of TMPP liposome was complete as compared with that of TMPP solution.
