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.

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 investigate the effect of different concentrations of heparin in the cold preservation solution on blood coagulation after reperfusion during orthotopic liver transplantation ( OLT) . Methods Forty ASA Ⅱ or Ⅲ patients with end-stage liver disease (31 males, 9 females) weighing 51-82 kg undergoing OLT were randomly divided into 3 groups according to the concentrations of heparin in the liver preservation solution: group Ⅰ 2 000 U?L-1( n = 14); group Ⅱ 8000 U?L-1(n= 12) and group Ⅲ 20 000 U?L-1(n = 12) .Anesthesia was induced with propofol, fentanyl and rocuronium and maintained with isoflurane inhalation and intermittent i.v. boluses of fentanyl. Body temperature was maintained at 35.5-37.5℃ and Hct at 22%-35% . Blood samples were taken from central vein at 15 min before reperfusion (T0,baseline) and 5, 30, 60, 120 and 180 min of reperfusion (T1-5) for determination of ACT, CR and platelet function (PF) using Sonoclot platelet function and coagulation analyzer (U.S.A.). Blood concentration of heparin was determined in 3-4 patients in each group at T0-5 ( HPLC) . Results The 3 groups were comparable with respect to age, body weight, ASA physical status and Child classification. The glass ball activated coagulation time (gbACT) was significantly prolonged at T1-4 in group Ⅲ and at T1,2 in group Ⅱ as compared to the baseline values at T0 ( P

Objective To accurately detect ECG P wave,a P wave detection algorithm based on fitting function in the optimal interval is proposed and evaluated in this paper,for resolving very difficult problems.Such as differences of positions and figures in ECG P wave as well as easily suffered diversified interferences.Methods In this algorithm the quadratic function to fit the P wave with least square method in every interval was used,which was shifted in local range.Then the optimal fitting interval of P wave was found by comparing the error of fitting.Finally,the characteristic points of P wave were obtained with the fitting function to fit P wave in the optimal interval.Results The performance of this algorithm tested with the records of the MIT-BIH database was effective and accurate.Conclusion This algorithm on the wide range of heart rate variation and small P wave of ECG P wave detection has good effect.Also it has some capabilities of anti-interference and quite low dismissal probability in particular.

Objective To explore the effectiveness and significance of neuronavigation in transsphenoidal approach microneurosurgical treatment of pituitary adenoma.Methods A total of 12 patients with pituitary adenomas underwent transsphenoidal surgery.Before the surgery a continuous CT or MRI scanning was adopted,and then the data were inputted into the neuronavigation system for 3-D reconstruction and registration.During the surgery,real-time positioning of the anatomic midline,the anterior wall of the sphenoidal sinus,and the floor of the sella turcica was employed by using the neuronavigation system,as well as the identification of the cavernous sinus and the internal carotid artery to avoid unexpected injury.The extent of tumor resection was assessed postoperatively.Results The mean fiducial error was 2.13?0.94 mm,and the accuracy of targets was

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
