AIM:To compare the difference between Shuxiong Tablet(Radix et Rhizoma notoginseng,Flos Carthami,Rhizoma Chuanxiong)(SXT) and its effective compounds group(SECG) in anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.METHODS:We adopted experiments of carrageenan-induced paw edema,hot water shrink trail,clotting time in mice,and thrombus in arteriovenous shut,and pituitrin induced acute myocardial ischemia in rats.RESULTS:Both of SXT and SECG could inhibit the tumefaction,decrease PGE_2 and SOD in inflammatory tissue;enhance the pain threshhold of mice;extend clotting time;inhibit the thrombosis;inhibit myocardial ischemia,significantly decrease CK,LDH,MDA and increase SOD in myocardial tissue.CONCLUSION:SXT and SECG have the same effects on anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.Further more,their dose-response relationship curves were similar,suggesting that SECG having the main effective components of SXT,could take place of SXT in clinical research.

ObjectiveThe purpose of this study is to discuss the diagnostic accuracy of nornalized liver ADC using the spleen and renal cortex as reference organs for the diagnosis of liver fibrosis.Methods Forty three patients with liver disease (chronic liver disease group) at compensated stage and 10 healthy volunteers (control group) were retrospectively assessed with diffusion-weighted imaging at a 3.0 T MR unit.Liver ADC,spleen ADC,renal ADC and normalized ADC (defined as the ratio of liver ADC to spleen ADC or renal cortex ADC,S-ADC and R-ADC for short) were measured in patients stratified by fibrosis stage.Spearman analysis was used to see the correlation between fibrosis stages and ADC,one-way ANOVA was used to compare the ADCs in different fibrosis stages.Logistic regression analysis was used to determine the performance of ADC for prediction of liver fibrosis,and show the area under the curve ( AUC),sensitivity and specificity choosing the optimal cutoff value that maximized the Youden index.ResultsTen volunteers belonged to SO stage.From SO to S4 stage,there were 2,5,9,12 and 15 patients,correspondingly,liver ADCwere (1.37±0.13) ×10-3,(1.33±0.16) ×10 -3,(1.17±0.16) ×10-3,(1.23±0.14) ×10-3and ( 1.12 ±0.11 ) × 10-3mm2/s,S-ADC were 1.86 ±0.18,1.68 ±0.12,1.34 ±0.14,1.48 ±0.15 and 1.34±0.10,R-ADC were 0.71 ±0.08,0.68 ±0.12,0.61 ±0.09,0.64 ±0.11 and 0.60 ±0.08respectively,and the differences among them were significant ( F =6.48,18.70 and 3.04,P ＜0.05 ).The correlation between fibrosis stage and S-ADC was stronger than between fibrosis stage and liver ADC,R-ADC (r =- 0.71,- 0.51,- 0.41 ;P ＜ 0.01 ).S-ADC was superior to liver ADC and R-ADC for detection of S2,S3 and S4 fibrosis stage (Youden index:0.91,0.58,and 0.59).ConclusionSpleen normalized liver ADC improves diagnostic accuracy for detection of liver fibrosis than liver ADC and renal normalized liver ADC.

A descriptive study to investigate the situation of cross-cultural adaptation and health status among medical international students was carried out using cluster sampling method and self-designed questionnaire in Dalian Medical University.148 international students come from 24 countries.There are 5 religions belief among these students.Islam,Catholic,Hindu,Buddhism and Sikhism.The main obstacles of cross-cultural adaptation are language,accommodation and diet.Economic status and stress of interpersonal relationship are also the main causes affecting the physical and mental health of medical international students.

BACKGROUND: Endothelial cell structural and functional integrity is importnat decisive fatcor for ischemic time-window and hemorragic transformation follwing brain ischemic injury.OBJECTIVE: To investiagte the endotheliocyt endurance to various course of ischemic injury basing on dynamical observation of morphological and ultrastructural changes of endotheliocyte during IR injury.DESIGN: Randomized controlled experiment.SETTING:Neurological Internal Department of the Second Affiliated Hospital of Jinan University.MATERIALS: This experiment was carried out in the Animal Experimental Laboratory of the Second Affiliated Hospital of Jinan University from March 1998 to March 1999. Totally 53 SD rats were randomly dihours of 6 rats.METHODS: Thread-bolt occlusion method was used to establish focal brain ischemia model on rats. Brain tissue was evenly cut into five coronary segments: namely A, B, C, D and E, segments C underwent TTC staining for marginal region location. segments D was taken for routine dehydration, transparency, envelop, slice and HE staining,optical microscopic observation. Ischemic surrounding area and central brain tissues was obtained from slice B, fixed and enveloped before cutting into ultrathin slices that was observed under transmission electron microscope.the occurring time of hemorrhagic infarction at different ischemic time cell vacuolization degree in foot process layer at different ischemic time points.RESULTS: Totally 53 rats were enrolled in this experiment and all data was entered into results analysis. Under optical microscope: Neuropil loose and small vascular surrounding edema was observed at ischemia 3 hours.Small arterial broken and hemorrhage occurred at ischemia 12 hours reperfusion 3 hours. Under electron microscope: Capillary endothelial nuclear swelling was observed at ischemia 3 hours, with cytoplasmic pinocytosi increasing and vacuolization in foot process layer appearing+; At ischemia 3 hours reperfusion 3 hours, the foot process layer vacuolization in center area was (++) and (+++) in marginal area; while at ischemia 6 hours reperfusion 3 hours, endothelia tight junction opened and vacuolization in foot process layer was (+++); pinocytosis was found obviously reduced after ischemia 12 hours reperfusion 3 hours, mitochondrial swelling was seldom observed, but tight junction increasingly opened and vacuolization in foot process layer appeared (+++) - (++++).CONCLUSION: Obvious structural changes of endotheliocyte appeared in post-ischemia 3 hours, endotheliocyte tight junction openning was observed at ischemia 6 hours, and hemorrage transformation occurred after ischemia 12 hours, mainly at the post-reperfusional ischemia center.

Objective To investigate the feasibility and safety*with the low dose fentanyl for valve replacement fast track cardiac anesthesia. Methods 40 cases with cardiac valve replacement were divided into two groups,group Ⅰ :20 cases with fast track anesthesia,group Ⅱ :20 cases with large dose fentanyl anesthesia. The blood presure, HR, SpO2, CVP,Temperature, airway pressure were observed at different time points. The postoperative extubation time,ICU stay,hospital stay,postoperative pulmonary complications were recorded. Results The fentanyl(μg/kg) of group Ⅰ (23. 25 ± 1.32) was less than that of group Ⅱ ( 35.75 ± 6. 84) ( P < 0. 05 ); Extubation time (hours), ICU stay ( hours),length of stay (days) were ( 7.92 ± 3. 16), (25. 12 ± 7.50), ( 28.50 ± 8. 94 ) in group Ⅰ , and that were (13.70±5.63) ,(37.53 ±13. 19) ,(38.00 ± 12. 90) in group Ⅱ. The group Ⅰ were shorter than the group Ⅱ ,P<0. 05; There were four cases of lung infection in group Ⅱ, no one in group Ⅰ ( P < 0. 05 ); There were significant differences between the two groups. There were no significant differences in the remaining observations. Conclusion The low dose fentanyl anesthesia for fast track anesthesia in heart valve replacement surgery was reliable and safe;It could help to reduce postoperative extubation time, ICU stay time and hospital stay time and reduce postoperative pulmonary complications and hospital costs.
