Objective: The Fourier transform infrared spectroscopy (FT-IR) and two-dimension IR correlation infrared spectroscopy (2D-IR) were used for the identification of Paeoniae Radix Alba and Paeoniae Radix Rubraand their alcohol extracts. Methods: The FT-IR spectra method and 2D-IR correlation spectra method were used. Results: The structural information of samples indicated that Paeoniae Radix Alba and Paeoniae Radix Rubra contained a large amount of calcium oxalate and starch, since some characteristic absorption peaks of the calcium oxalate could be observed; And some characteristic absorption peaks in the range of 950-1 200 cm-1 of the starch can be observed, but their shape and location revealed minor differences. In the secondary derivative infrared spectra (SD-IR), both Paeoniae Radix Alba and Paeoniae Radix Rubra can be observed with the characteristic absorption peaks which in 518/517, 989 cm-1 and so on. Besides, these peaks at 989, 1 015, 1 052, 1 078, 1 105, and 1 161 cm-1 of Paeoniae Radix Rubra, almost of them which are single peak, were stronger than Paeoniae Radix Alba's and the same peaks in Paeoniae Radix Alba were jagged peaks, showing that the difference were related to the contents and structure of starch in Paeoniae Radix Alba and Paeoniae Radix Rubra. The characteristic absorption peaks of the peoniflorin which arouse at 1 716, 1 451, 1 347, 1 277, and 714 cm-1 in the FT-IR spectra of their alcohol extracts can be found. Moreover, the shape and intensity of the peaks were more distinct in the secondary derivative IR spectra of the different parts. For example, in the range of 900-980 cm-1, Paeoniae Radix Alba presented two groups of peaks: 935, 919 cm-1 (strong) and 962, 949 cm-1 (weak), while Paeoniae Radix Rubraonly presented one group of peaks: 941, 920 cm-1 (middle), showing that the difference was related to the content and structure of glucoside in Paeoniae Radix Alba and Paeoniae Radix Rubra. In the 2D-IR spectra, both had five auto-peaks at 887, 968, 1 008, 1 190, and 1 305 cm-1, which were the auto-peaks of glucoside, but the strongest auto-peak of Paeoniae Radix Alba was at 1 190 cm-1 and that of Paeoniae Radix Rubra's was at 968 cm-1. The spectra testified the glucoside compounds in Paeoniae Radix Alba and Paeoniae Radix Rubra were different. Conclusion: A lot of information of Paeoniae Radix Alba and Paeoniae Radix Rubra can be provided by FT-IR spectra method and 2D-IR correlation spectra method which can testify that the content and structure of substance in Paeoniae Radix Alba and Paeoniae Radix Rubra were different and can be used to analyze and distinguish Paeoniae Radix Alba and Paeoniae Radix Rubrapreliminarily which can make a good foundation for further research.

Caco-2 cell monolayer model is widely utilized in drug absorption study and 12-well transwellTM plates were commonly used to study the absorption of different kinds of natural products. To establish a stable method for the study of traditional Chinese medicine prescription, 6-well plates were chosen because of the larger well volumes than 12-well plates. To study the impacts of collagen kinds, coating density as well as coating time on the cell culture, the transepithelial electrical resistance of Caco-2 cell monolayers grown on different collagen coating transwells was determined, and the permeations of propranolol and atenolol as standard markers were detected with HPLC. The results showed that the kinds of collagen, the different coating densities and coating time of rat tail collagen had no significant influences on the Caco-2 cell monolayer integrality and absorption capacity. 6-well plates coated with 2 micro g Scm-2 rat tail collagen for 1 hour were enough reliable and suitable for the study of traditional Chinese medicine prescription in vitro.

Objective To evaluate the relationship of myocardial MR contrast delay-enhancement and nuclear perfusion-metabolism pattern in patients with idiopathic dilated cardiomyopathy (IDCM).Methods Forty-two consecutive patients (29 men and 13 women,age:(53 ±12) years) diagnosed clinically with IDCM were enrolled.All patients underwent 99Tcm-MIBI SPECT,18F-FDG PET imaging and MR contrast delay-enhancement imaging within 3-7 d.The myocardial perfusion-metabolism segment analysis was performed using a 17-segment model.Segmental 99Tcm-MIBI and 18F-FDG uptakes were scored visually using a 4-grade scoring system (0 =normal uptake,1 =mildly reduced uptake,2 =moderately reduced uptake,3 =severely reduced uptake).Patterns of perfusiorn/metabolism were classified as normal,mismatch,mild-to-moderate match and severe match.Myocardial MR contrast delay-enhancement was classified into 3 categories (non,mid-wall and transmural delay-enhancement).x2 test was used to analyze the differences of perfusion/metabolism patterns among non,mid-wall and transmural delay-enhancement groups and the myocardial MR contrast delay-enhancement incidence among four perfusion/metabolism groups.Resuits Among the 42 patients,myocardial delay-enhancement was present in 18 patients,of which 94.4％ (17/18) showed abnormal myocardial perfusion/metabolism patterns and only 33.3 ％ (8/24) patients without abnormal myocardial delay-enhancement had abnormal myocardial perfusion/metabolism patterns (x2 =15.944,P ＜ 0.001).Perfusion/metabolism patterns varied in three different categories of non,mid-wall and transmural delay-enhancement (x2 =14.276,P ＜ 0.001).The normal peffusion/metabolism pattern proportions in the non,mid-wall and transmural delay-enhancement groups were 86.2％ (526/610),71.0％ (44/62) and 28.6％ (12/42),respectively.The incidence of transmural delay-enhancement (44.4％ (12/27)) was significantly higher in segments with severe match than that in the other 3 groups (normal:2.1％ (12/582) ; mismatch:18.1％ (15/83) ; mild-to-moderate match:13.6％ (3/22) ; x2 =112.530,P ＜ 0.001).Conclusions MR contrast delay-enhancement is much more sensitive in detecting moderate fibrosis,while nuclear perfusion-metabolism imaging can detect more impaired but viable myocardium.Combining the two imaging modalities is useful for providing comprehensive evaluations of myocardial injury in patients with IDCM.

ObjectiveTo investigate the effect of intrathecal (IT) Ro25-6981 (a selective NR2B receptor antagonist) on focal cerebral ischemia-reperfusion (I/R) injury in rats.MethodsSixty healthy male SD rats weighing 280-320 g in which IT catheter was successfully implanted without complication were randomly divided into 4 groups ( n ＝ 15 each):group sham operation (group S) ; group focal cerebral I/R(group I/R) ; group I/R + Ro25-6981 (group Ro) and group I/R+ normal saline (group NS).The right middle cerebral artery was occluded for 2 h with a nylon thread with rounded tip which was inserted into right internal carotid artery and advanced cranially until resistance was met in groups I/R,Ro and NS.In group Ro Ro25-6981 100 μg/10 μl was injected IT at 0,2,23 h of reperfusion,while in group NS NS was injected IT instead of Ro25-6981.Neurological dificit was assessed and scored (0 ＝ no deficit,3 ＝ severe deficit) at 24 h of reperfusion.The infarct size was determined by 2,3,5-triphenyl tetrazolium chloride staining.ResultsIT administration of Ro25-6981 significantly reduced cerebral I/R-induced infarct sized and neurological deficit score in group Ro as compared with groups I/R and NS.ConclusionRo25-6981 injected IT can protect the brain against local cerebral I/R injury.
