Objective To explore relationship between Liver and Spleen of Tradicational Chinse Medicine in T cell activation. Methods The expression of IFN-r and IL-4 of T cells in asthenic spleen qi model and hepatic depression model was detected by RT-PCR. Results IFN-r level of T cells in asthenic spleen qi model significantly decreased, in hepatic depression model significantly increased, in asthenic spleen qi model treated with decoction of four mild drugs rose to normal range, and in hepatic depression model treated with powder of bupleuri dispersing stagnated hepatic qi fell to normal range. The IL-4 level of T cells in asthenic spleen qi model significantly increased, in hepatic depression model significantly decreased, in asthenic spleen qi model treated with decoction of four mild drugs fell to normal range, and in hepatic depression model treated with powder of bupleuri dispersing stagnated hepatic qi rose to normal range. Conclusion Liver and spleen are related to the regulation of THO cells functions.

Objective To observe the effect of Ultra-micro-LiuweiDihuang Decoction on the embryo brain development and the influence on brain growth hormone(GH),Somatostatin(SS)in prengnant mice of passive smoking,then to demonstrate the relationship between brain and kidney in TCM.Methods Animals were divided into 5 groups at random:normal group(A),model group(B),traditional Liuwei Dihuang Decoction group(C),1/3 dosage of Ultra-micro-LiuweiDihuang Decoction group(D)and all dosage of Ultra-micro-LiuweiDihuang Decoction group(E).The IUGR model was established by passive smoking.On the 19th day of gestation,all mice were anatomized to scale the body and brain weight of lively embryos,then a part of brain tissue was homogenated.The levels of GH and SS in brain tissues were measured by ELISA.Results Passive smoking could decrease the body and brain weight,influence the level of GH and SS in brain tissues.Compared with A and B groups,the C,D and E groups could increase body and brain weight,regulate the level of GH and SS,improve the brain development of IUGR mice obviously(P

AIM: To determine the HPLC fingerprint of ultramicro decoction piece of Radix paeoniae Alba. METHODS: HPLC was used to analyze the extracts of ultramicro decoction piece of Radix paeomae Alba from 10 different sources. RESULTS: The fingerprint of ultramicro decoction piece of Radix paeoniae Alba was composed of 20 peaks,among which there were 10 characteristic peaks. CONCLUSION: The fingerprmt can be used to control the ultramicro decoction piece of Radix paeoniae Alba qualities.

AIM: To provide a HPLC fingerprint of Fructus aurantii micropowder in order to create a basis for(identification.) METHODS: With the help of computer similarity evaluation,Seventeen kinds of Fructus aruantii sample were pulverized and micronized separately,then were extracted by methanol and compared correlation between both extracts. RESULTS: In methanol extraction,contents of aurantiamarin,hesperidin and neohesperidin in micropowder were more than that in pulverized powders,correlation of both HPLC fingerprint was 0.9~1.0. CONCLUSION: The method established can be used for identifying and evaluating crud drug of Fructus aurantii,and further prove that micronization is beneficial to increasing flavonoid dissolution.

AIM: To provide application and identification basis for methanol-extratis of Fructus aurantii by constructing the HPLC-FP. METHODS: The C_(18) column was used with a mobile phase of(A)(0.095%) phosphoric acid acetonitrile-(B)(0.095%) phosphoric acid gradient elution.The flow rate was(1.0) mL/min.The wavelength of detecter was set at 330 nm.Naringin was reference standard. RESULTS: By cluster analysis,the eighteen kinds of Fructus aurantii samples were classified as four clusters: the superior in producing area,the ordinary in producing area,the ordinary and the inferior.By similarity calculation,the similarity of the superior in producing area and the ordinary in producing area were(0.9)～(1.0),and the ordinary and the inferior were less than(0.9). CONCLUSION: The HPLC-FP of Fructus aurantii has been established.The method can be used to identify and evaluate the quality of Fructus aurantii.

Objective: To provide experiment data for ultra fine prepared mineral drugs Methods: Electron microscope scannin,X ray diffraction were used in identification, atomic emit sectrum was used in determination. Results: The dissolution rate of ca 2+ composition could be high.The ultra fine prepared of minaral drugs could be prepared with powder diameter of K 4。 Conclusion: Ultra fine Prepared fluoritum and gypsum fibrosum may Save clinically dose.

Objective To compare the clinical efficacy of different doses of ultrafine extracted granule preparation (EGP) and traditional herbal decoction (THD) of Li Zhong Tang in treatment of epigastric pain. Methods Sixty cases of epigastric pain patients in accordance with the diagnostic criteria of deficiency and cold pattern of spleen and stomach in TCM were randomly divided into THD group, 1/3 dose group and 1/5 dose group, and were given THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP, respectively. The clinical efficacy of the three groups after one course of medication was comparatively analyzed. Results There were no significant differences in age, course of disease, symptom score before treatment, epigastric pain efficacy and syndrome curative effect among the three groups, the differences had no statistical significance (P>0.05). The severity, frequency and duration of epigastric pain were all reduced in the three groups, with significant differences between before and after treatment (P<0.05). Conclusion There are no significant differences in the clinical efficacy on epigastric pain among THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP. In addition, the effect of 1/3 dose group is very close to the THD group.

OBJECTIVE: To study the pharmacokinetic parameter and the relative bioavailability of ferulic acid in ordinary Guipi pills and ultramicro Guipi pills in rabbit.METHODS: HPLC-MS/MS was used to identify the concentration of ferulic acid in the blood sample.RESULTS: Plasma concentration of ferulic acid in ordinary pills was different from that in ultramicro pills.The main pharmacokinetic parameters of ferulic acid in ordinary pills vs.that in ultramicro pills were as follows:t1/2a:(17.59?2.57) min vs.(23.51?4.49) min;t1/2?:(300.91?38.74) min vs.(167.17?45.66) min;tmax: (9.61?1.69) min vs.(12.33?2.27) min;Cmax:(58.92?8.42) ng?mL-1 vs.(112.35?31.29) ng?mL-1;AUC: (5 851.67?895.49) ng?min-1?mL-1 vs.(8 586.13?1 497.62) ng?min-1?mL-1.There were significant difference in Cmax and AUC between ordinary pills and ultramicro pills.CONCLUSION: The application of super fine crushing technique in the preparation of Guipi pills could improve the bioavailability of Guipi pills.
