Object To develop a resonance scattering spectral(RSS) method for the determination of total flavone in Shuxuening Tablet, and study the cause of RSS enhancement. Methods The BSA Mo (Ⅵ) qucercetin (Qu) system was investigated by RSS method. Results There were two resonance sacttering peaks at 470 and 525 nm. The Qu concentration in the range of 0-2 4 mg/L is linear to the resonance scattering intensity I 470 nm , with a detection limit of 0 3 mg/L. Conclusion This method is simple, sensitive and suitable for the determination of total flavone in Shuxuening Tablet. The spectral results demonstrate that the formation of [BSA Mo Qu] n associated particle and the interface between the particle solid phase and water phase results to its enhanced RSS.

ObjectiveTo study the effect of behavior training on the expression of neural growth factor(NGF) in the dentate gyrus(DG) in rats with left lateral hippocampal infarction.Methods102 SD rats were randomized into fore-training,3 d,7 d,14 d,21 d,28 d,35 d,42 d,49 d training groups,fore-immobilization, 3 d、7 d,14 d,21 d,28 d,35 d,42 d,49 d immobilization groups and control group.Behavior training and immobilization were performed at 1st day after the infarction.Immunohistochemistry was used to detect the expression of NGF in the DG at different points of time.ResultsThe expression of NGF is certain in the normal DG of rats.The expression of NGF increased after infarction.However,the expression of NGF had obviously increased in fore-training groups compared with that in fore-immobilization groups.ConclusionBehavior training can accelerate the expression of NGF in the DG of rats with left hippocampal infarction.

Objective. To study the role of endogenous carbon monoxide (CO) in endotoxin shock. Methods. The changes of CO levels and the effects of zinc protoporphyrin IX (ZnPP),an inhibitor of heme-oxygenase (HO), in endotoxin shock and the efficacy of hemin,an inducer of HO were investigated.Results. The plasma CO levels were found to be significantly increased during the course of endotoxin shock. Injection of ZnPP was shown to abrogate the endotoxin-induced hypotension and metabolic derangements markedly. Administration of hemin to healthy rabbits revealed the hypotension and metabolic derangements similar to the animals given endotoxin.Conclusion.CO is a newly found endogenously produced mediator which may play an important role in the pathogenesis of endotoxin shock.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

Near-infrared (NIR) diffuse reflectance spectroscopy was used to analyze the impact of multi-class particle size of Chinese material medica (CMM) based on the spectral characteristics in overtone and combination region. Several types of CMM (60, 80, 100,120 mesh) were subjected to NIR spectra analysis. Spectral reproducibility was examined after sample repackage. The result showed that the effects of particle size on the NIR spectra were different according to different bands, in the combination region and first combination-overtone region. Spectroscopy intensity was proportional to the particle size and influence of particle size was greater as the wavelength increased. While in the second combination-overtone region, it was inversely proportional to particle size. To the sampling loading error, the result indicated that when the mesh number was larger than 60 mesh, the error was small. The appropriate particle size was clarified to guarantee the accuracy and reliability of NIR diffuse reflectance spectroscopy in CMM.

Objective To investigate the instant clinical efficacy of intra-arterial infusion of fasudil combined with routine anti-vasospasm for symptomatic cerebral vasospasm (SCVS). Methods The clinical data of 21 patients with subarachnoid hemorrhage (SAH) due to ruptured aneurysm, who were admitted to authors' hospital during the period from May 2010 and February 2014, were retrospectively analyzed. The lesions included Fisher gradeⅡ(n=2), gradeⅢ (n=16) and gradeⅣ (n=3). Endovascular embolization of the aneurysm was carried out within 48 hours after the confirmation of the diagnosis with total cerebral DSA;no bleeding occurred during the operation and routine anti-vasospasm therapy was given. Within 4-9 days after the onset of the disease, all 21 patients presented SCVS. Half dose systemic heparinization, superselective intra-arterial infusion of fasudil (30 mg fasudil+250 ml saline, lasting for 30 min) were adopted. Reexamination of angiography performed at 15 min after fasudil infusion was employed, and the results were evaluated with NIHSS score by comparing the preoperative findings. Results Imaging examination performed after the treatment showed that significant improvement was obtained in 15 patients and no obvious changes in 6 patients. Clinical symptoms were remarkably improved in 11 patients, partially improved in 4 patients and remained unchanged in 6 patients. The mean NIHSS score was improved from preoperative 28.6 to postoperative 21.2. Conclusion For the treatment of symptomatic cerebral vasospasm, superselective intra-arterial infusion of fasudil is effective and safe, and it has good clinical application value.

Objective To quantitatively study right ventricular function in the normal second and third trimester fetuses by M-mode tricuspid annular displacement(TAD).Methods TAD was measured using conventional M-mode echocardiography on 161 normal second and third trimester fetuses with gestation age (GA) between 19-38 weeks,meanwhile multiple parameters for evaluating right ventricular function were obtained using pulsed Doppler echocardiography (PW) and myocardial Dopple tissue imaging (DTI).The correlation between TAD and other parameters were analyzed using SPSS 17.0.Results In normal second and third trimester fetuses,the TAD was (9.38 ± 1.71)mm with a range of 5.79-13.90 mm,and was increased with the growth of GA.TAD was correlated with GA,E,A,Em,Am and Sm significantly (r =0.759,0.547,0.320,0.497,0.483 and 0.598 respectively,all P ＜0.001).TAD was not correlated with HR(P ＞0.05).TAD showed differences between the second trimester fetuses and the third trimester fetuses (P ＜ 0.05).Conclusions In normal second and third trimester fetuses,the TAD is increased with the growth of GA,and has good correlation with GA,E,A,Em,Am and Sm respectively,and may become a new promising modality to evaluate function of RV simply and accurately.The technique will be propitious to use in hospitals (without DTI) because of simplicity of operator and lower requirement on the technology and equipment precision.
