Objective To investigate the pharmacokinetic profiles of baicalin and wogonoside in diabe-tic rats in vivo,which are two major constituents in Huanglian-Jiedu Decoction(HJD).Methods The diabetic rats were induced by ip administration of streptozotocin(STZ).After the establishment of the method and the set-up of diabetic rats,the pharmacokinetic profiles of baicalin and wogonoside were investigated.Diabetic and normal rats were ig HJD extract,and then the blood samples were collected at the given time points.Contents of baicalin and wogonoside in diabetic and normal rat plasma were assayed by HPLC-UV method.The pharmacokinetic parameters(except Cmax and tmax) were analyzed by noncompartmental method.The area under the serum concentration-time curve(AUC0-t) was calculated using trapezoidal rule to the last point.Moreover,the presystemic metabolism of baicalin was investigated and compared to explore the pharmacokinetic difference by fermentation of baicalin in feces suspensions of normal and diabetic rats,respectively.Results The pharmacokinetic parameters of baicalin in normal and diabe-tic rats were:(4.50?1.92) and(7.5?1.0) h for tmax 2;(2.83?0.25) and(9.54?2.87) ?g/mL for Cmax1,(2.56?0.63) and(6.58?1.15) ?g/mL for Cmax2;(37.58?7.57) and(92.75?24.62) ?g?h/mL for AUC(0～24),(6.6?2.4) and(12.64?3.35) h for t1/2,respectively.And the pharmacokinetic parameters of wogonoside in normal and diabetic rats were:(5.5?1.0) and(8.00?1.63) h for tmax 2;(1.36?0.17) and(6.16?1.40) ?g/mL for Cmax1;(1.58?0.17) and(4.11?0.76) ?g/mL for Cmax2;(27.02?3.72) and(58.16?16.43) ?g?h/mL for AUC(0～24);(9.72?2.24) and(7.89?1.63) h for t1/2,respectively.The results indicated that Cmax1,Cmax2,AUC(0～24) of baicalin and wogonoside were significantly enhanced and t1/2 of baicalin was remarkably extended when compared with the normal rats.And the results also revealed that baicalin contained in HJD hydrolyzed more rapidly when incubated in the feces suspension of diabetic rats than in that of normal rats.Conclusion The results indicate that the pharmacokinetic difference of baicalin between diabetic and normal rats may result from the presystemic metabolism of baicalin.

METHODS: HPLC with ZORBAX SB-C 18 column was used, the mobile phase was a linear gradient of methanol containing 1% acetic acid and water containing 1% acetic acid in 40min, the detection wavelength at 312nm. RESULTS: 12 marker peaks were separated. The methodological evaluation showed that the method had a good repeatability, and the marker peak area ratio of different samples were different. CONCLUSION: This method is simple and accurate with good reproducibility and can be used for a quality control for Crocus sativus L.

Objective To observe the effects of different doses of human recombinant tissue factor pathway inhibitor-1 (TFPI-1) on no-reflow (NR) phenomenon in rabbit.Methods Fifty-two New Zealand white rabbits were subjected to coronary artery occlusion for 120 min and followed by reperfusion for 60 min,and then were randomly (random number) assigned into four groups:control group,large,moderate and low doses TFPI-1 groups ( 1000 ng/kg,100 ng/kg,10 ng/kg bolus and thenl0 ng/kg,1 ng/kg and 0.1 ng/kg per minute infusion for maintenance,each group n =13).The no-reflow area (NA) and ischemic area (IA) was measured by thioflavin S and Evan's blue.The NR severity was expressed by NA/IA.The difference in NR severity was compared between groups.The thrombi and myocardial injury were observed under light microscope.The infarction and NR severity in different groups were compared by using one-way ANOVA followed by LSD procedure.Results There were no significant differences in IA and body weight among four groups (P＞0.05).NR severity in the large,moderate,low doses TFPI-1 groups and control group were (0.210 ±0.061 ),(0.389 +0.110),(0.478 ±0.077) and (0.536 ±0.061 ),respectively.NR severity in the large dose TFPI-1 group was slightest among the four groups (P ＜0.01 ).NR severity in the moderate dose TFPI-1 group was significantly decreased than that in control group ( P ＜ 0.01 ) and in low dose TFPI-1 group (P ＜0.05 ).There was no significant difference in NR severity between the low dose TFPI-1 group and control group ( P ＞ 0.05 ).There was less thrombus formation and lower grade myocardial injury found in the large dose TFPI-1 group. Conclusion Human rTFPI-1 might lessen NR severity in rabbit in dose-dependent,suggesting the option on human rTFPI-1 for treatment of NR phenomenon.

AIM：To analyse sequences of p62dok amino acid and cDNA and to investigate p62dok tyrosine phosphorylation and its relation with p21ras GAP. METHODS：The purified p62dok was extracted from CHO/IR cells. The peptide sequence of p62dok was carried out on a high performance analyzer. PCR was performed with the primers designed from the sequence of p62dok amino acid. Western blot and immunoprecipitation were used to identify tyrosine phosphorylation of p62dok and the binding of p62dok with p21ras GAP. RESULTS：The p62dok cDNA is a 1863 bp sequence and code 481 amino acid with 15 tyrosine residues and a putative pleckstrin homology domain. The p62dok protein is rich in PxxP motif. The tyrosine-phosphorylated p62dok can bind p21ras GAP. CONCLUSION：Perhaps p62dok is a new signaling molecule and play an important role in insulin signaling networks through RAS/MAPK pathway.

Objective To survey the current living situation, protection condition, suggestions and demands of protective items and inheritors of TCM intangible cultural heritage;To analyze existing problems and solutions of protection;To lay the foundation for further protection. Methods Survey was carried out through table investigation and meeting and convention from the aspects of item overview, situation of inheriting community, protection status, and demands and suggestions. Results TCM intangible cultural heritage is inherited through traditional teaching and learning between masters and apprentices, and family inheriting. Some inheriting communities are too small, and some inheritors are too old, which make the inheriting prospect quite gloomy. Protective levels of items of TCM intangible cultural heritage vary. Most items are protected by protective institutions, protective personnel, and learning-teaching sites. Some items are supported by protective fund;archive data about the items are filing;researches and work about propaganda and education are also carried out. Conclusion Protection of TCM intangible cultural heritage has made certain achievements. However, some problems about funds, inheriting, filing, training, and propagandizing should be solved.

Objective To probe into the feasibility and efficacy of damage control surgery (DCS) in treating severe pelvic fracture combined with abdominal organ injuries.Methods A retrospective analysis was done on the clinical data of 39 patients with severe pelvic fractures combined with abdominal organ injuries treated by DCS from 1995 to 2010.Results Devascularization of internal iliac arteries was performed to treat massive hemorrhage in the 39 patients with severe pelvic fractures combined with abdominal organ injuries,including ligation of bilateral internal iliac arteries in 31 palients and angioembolization of bilateral internal iliac arteries in eight.Meanwhile,early pelvic external fixators were used in 31 patients.All patients received discriminating internal fixation after resuscitation in ICU.The overall mortality rate was 21％ (8/39),with average ISS of 41.6 points and with hemorrhagic shock and combined injury for the main causes of death.Complications occurred in seven patients including combined acute respiratory distress syndrome (ARDS) in three patients,thrombosis of right common iliac artery in one,subphernic abscesses in two,and deep infection of lower extremity in one,but all the complications were cured.Conclusions Reasonable and timely use of DCS can enhance the rescue survival rate of patients with severe pelvic fraclure combined with abdominal organ injuries.
