Because of the relationship between the quality and the processing technology of Chinese herbal pieces was very close, we proposed concerning the problems of Chinese herbal pieces characters and processing experi-ence. Then, we made use of intelligent sensory technique to objectively express the characters of Chinese Herbal pieces, and explored to set the methods and models about evaluating the quality of Chinese herbal pieces of appear-ance characters and internal quality. To realize the expression of experience terms such as huoli and huohou in the process of Chinese herbal pieces objectively, we adopted on-line infrared temperature measurement and biologi-cal evaluation technologies, and established new technologies and methods of Chinese herbal pieces process quality control in the process.We established a workable monitoring technology, which could not only achieve the controlla-bility and stability of processing quality, also ensured the safety and effectiveness of Chinese herbal pieces.

Objective To construct the genes expression profile database of experimental autoimmune encephalomyelitis (EAE) mice model and to screen the high candidate genes with microarray analysis. Methods Polymerase chain reaction (PCR) products on behalf of 4 096 genes from mixed mice tissue library were assembled on the modified Oako glass slide. The general RNA from 6 EAE mice model and 6 normal mice head was transcripted into cDNA by RT-PCR and labelled with cy-3 and cy-5.6 groups each consist one EAE mice and a control. These two probes were mixed and hybridized with the above mentioned gene chips. Scan array 4000 was used for scanning the hybridizing signals and GenePixPro 3.0 for date analysis. Results Of the total 4 096 genes monitored, 43 genes in group one showed changes in expression level of the ratio outside 0.5 and 2, 30 genes differed in group two, 176 genes changed in group three, 76 in group four, 294 in group five and 129 in group six. Conclusions The results showed the consistent different genes expression throughout the EAE mice model. The genes related to immune, cell structure, cell cycle, ion channel, signal transduction, protein synthesis and metabolism are involved in EAE pathogenesis. The results provide deeper insights into the mechanism of EAE and multiple sclerosis.

Traditional Chinese medicine placebo has been put more and more attention to. However, there is no ac-cepted quality evaluation method for TCM placebo. How to evaluate TCM placebo objectively and quantitatively is a common problem in the industry of Chinese medicine. New technologies such as the Intelligent Sensory Technique have been used to establish the placebo evaluation methods which are suitable for TCM characteristics. This article provided the basis for establishing scientific, rational and objective evaluation guiding principles for TCM.

Objective To establish a HPLC method for the determination of gastrodine in Tianma Formula Granule.Methods A HPLC was performed on Shim-pack VP-ODS(4.6mm? 150mm,5? m).The mobile phase consisted of acetonitrile and 0.1 % H3PO4(3∶ 97).Detected wavelength was at 220 nm,the flow r ate was 0.5 mL? min-1,column temperature was at 25 ℃,and the injection volume was 5 ? L.Results The linearity was good in the range of 0.1020～0. 6120 ? g for gastrodine(r=0.9999).The average recovery rate was 100.5 %, and RSD was 1.01 %(n=5).Conclusion The established HPLC method is simple,accurate,and suitable for the determination of gastrodine in Tianma Formula Granule.

Objective To assess the association of tag single nucleotide polymorphisms ( tag SNPs) of SH2B adap-tor protein 3 ( SH2 B3 ) gene with essential hypertension ( EH ) in Han population .Methods Six tag SNPs ( rs7309325 , rs11065898 , rs10849947 , rs2239196 , rs2238154 and rs739496 ) were genotyped in 510 patients with EH and 510 healthy controls using polymerase chain reaction-restriction fragment length polymorphism method ( PCR-RFLP) .Results Compared to CC genotype , the T allele carriers of rs2239196 were more likely to be hy-pertensive ( OR=2.59 ,95%CI 1.36-4.96 ,Bonferroni correction P<0.05 ) .Conclusions The rs2239196 T al-lele is potential a risk factor of EH in Han population .

Background Streptozotocin (STZ)-induced type 1 diabetic model is an acceptable model and is often used to the study of diabetic retinopathy (DR).However,the model is often established using retinal digest preparation in vitro in albino rats,and therefore it is difficult to evaluate the change of retinal vessels by fundus fluorescein angiography (FFA) in vivo.Recently,pigmented rats are being used as the DR model.But the study on the comparison between albino rat model and pigmented rat model is seldom.Objective This study was to observe and compare the manifestations of FFA and retinal digest preparation in early diabetic pigmented diabetic rat and albino diabetic rat,and to select the right model of DR using FFA.Methods Type 1 diabetic models were induced in 15 six-week-old health male BN rats and 15 six-week-old health male SD rats by the injection of STZ (55 mg/kg) via tail vein.The models were thought to be successful in the rats with the blood glucose level ≥ 16.7 mmol/L.The right eyes of the rats were extracted 6 weeks after injection of STZ.Lens were examined by slit lamp microscope.Retinal vascular changes were examined by fundus photography,FFA and periodic acid Schiff staining of retinal digest preparation.The manifestations of FFA and retinal digest preparation were contrasted between BN rats and SD rats.The number of eyes with lens opacification was compared by Chi-square test and the ratio of vascular endothelial cells and perithelial cells (E/P) was compared between BN rats and SD rats.The use and care of experimental animals complied the Statement of Ethic Committee of Tianjin Medicine University.Results Six weeks after injection of STZ,11 BN rats and 10SD rats were included in this study.The blood levels were (24.73±2.98) mmol/L and (22.36±3.65) mmol/L in BN rats and SD rats,respectively,without significant difference between the 2 types of rats (t =7.873,P＞0.05).Lens opacification occurred in 6 BN rats and in 5 SD rats (P=0.717).FFA showed the clear retinal vascular under the brown background.Evident vessel disorder and fluorescence leakage like background stage of DR were seen in 9 eyes.However,in the SD rats,retinal vessel abnormality could not exhibited owing to the interference of choroid fluorescent light from choroidal vessels and vortex vein.Retinal digest preparation exhibited that unevenness of vessel diameter,decrease of perithelial cells and increase of endothelial cells in both types of rats.The E/P values were 11.50±3.68in the BN rats and 12.86±3.94 in the SD rats,without significant difference between them (t=9.785,P＞0.05).Conclusions The abnormality of fundus vascular morphology can be better displayed in pigmented diabetic rats than albino rats by FFA in vivo.
