OBJECTIVE To study the effect of qingxin kaiqiao formula and saponin on the learning and memory ability and the expression of the apoptosis signal transducers Abeta and betaAPP in AD rat brain. METHOD The comparative observation method was adopted for the animal test. Forty male SD rats were randomly divided into five groups, namely the normal group, the model group, the aricept group, the qingxin kaiqiao formula group and the saponin group, with eight rats in each group. Abeta(25-35) (10 g x L(-1)) was injected into their bilateral amygdala to establish the AD rat model. Since the next day, they were intragastrically administered with Aricept (1.67 mg x kg(-1)), Qingxin Kaiqiao decoction (12.67 mL x kg(-1)), saponin (6.30 mg x kg(-1)) and double distilled water filling for 2 weeks to observe their spatial memory ability in a Morris water maze and study the expression of Caspase-3, Abeta and betaAPP in brain tissues by immunohistochemistry. RESULT Each traditional Chinese medicine groups showed significant improvement in the learning and memory ability of AD rats and notable differences (P < 0.05, P < 0.01) compared with the control group. The qingxin kaiqiao formula group and the saponin group showed a decrease in the expressions of Caspase-3, Abeta and betaAPP in cerebral cortex and hippocampus area, displaying notable differences (P < 0.01, P < 0.05) compared with the control group. CONCLUSION qingxin kaiqiao formula and saponin can obviously improve the learning and memory ability of AD rats with by decreasing the expression of Caspase-3, Abeta and betaAPP in cortex and hippocampus.

OBJECTIVE: To establish the drug release method of multi-drug delivery system of tongmai pellets. METHOD: The drug releasing characteristics were researched by HPLC and UV spectrophotometric method. The drug releasing characteristics of the multi-drug delivery system of tongmai pellets between single unit and multiple drug delivery system were evaluated by HPLC. RESULT: The four pellets release unit isoflavones pellets, tanshinone pellets, Sal pellets, chuanxiong acid by ultraviolet spectrophotometry and HPLC method of dissolution obtained similar curves, and the similarity factor f2 were 63.31, 81.59, 70.93, 68.08. The release unit after the formation of multiple drug delivery system had no influence on single unit.

OBJECTIVE: Plant metabolomics combined with GC-MS was used to investigate metabolic fingerprinting of Tussilago farfara at different growth stages. METHOD: Dried Samples were extracted by two-phase solvent system to obtain polar and nonpolar parts, which were subjected to GC-MS analysis. Metabolites were identified by NIST data base search and comparison with the authentic standards. The data were introduced into SIMCA-P 11.0 software package for multivariate analysis after pretreatment. RESULT: Fifty-four metabolites were identified, including 35 polar metabolites and 19 nonpolar compounds. The score plot for PCA showed clear separation of the different development stages of flower buds of T. farfara, showing a trend of gradual change. Samples of October, November, December were in close proximity on the plot, indicating that the metabolome of these three periods was similar, samples from September (early development) and March (after flowering) were far away, showing big chemical differences. Content comparison results of some representative metabolites reveals that, the content of proline, lysine and linoleic acid increased gradually to the highest in the medium term, but sharply decreased to the lowest after flowering; the content of malic acid and citric acid were the lowest in the medium term; sucrose content decreased gradually, and then reached the lowest level after blooming. CONCLUSION: It is obvious that metabolites of the early development and flowering stage were quite different with those of the traditional harvest time, suggesting that they can not be used as traditional medicine. This study will provide a research basis for harvest time determination and bioactive compounds of T. farfara.

: The development of traditional Chinese medicine lies in its significant clinical efficacy which is closely related to the bioavailability of drugs. The nature of the material foundation of compounds of traditional Chinese medicine is reflected in multi-component. As for the nature of components themselves, the level of their bioavailability depends on the biopharmaceutical properties, namely solubility and permeability, to a great extent. Therefore, under the guidance of the theory of traditional Chinese medicine and in the combination with modern preparation techniques, this essay reveals key techniques capable of improving the biopharmaceutical properties of components, in the hope of enhancing the clinical efficacy of components of traditional Chinese medicine.

OBJECTIVE: To study the effect of sophoridine and TLR4/MD-2 blocking agent on pathway of LPS-induced RAW264. 7 macrophage TLR4-NF-kappaB-TNF-alpha in and its pharmacological mechanism of antiendotoxin. METHOD: RAW264. 7 macrophages were cultured and divided into 5 groups, namely the blank control group, the LPS model group, the sophoridine + LPS group, the TLR4/MD-2 blocking agent + LPS group and the anti-TLR4/MD-2 + sophoridine + LPS group. Cells and cell culture fluids were collected at 120 min after the each group was processed. The expression of TLR4 protein was measured by western blot, the distribution and expression of NF-kappaB protein were measured by immunocytochemistry, and the expression of NF-kappaB and TNF-alpha mRNA were measured by western blot and reverse transcriptase polymerase chain reaction (RT-PCR). The content of TNF-alpha in the cell supernatant was detected by using radioimmunoassay. RESULT: Compared with the LPS group, the expression of TLR4 protein, NF-kappaB mRNA, the rate of NF-kappaB entry the nucleus, TNF-alpha mRNA and TNF-alpha content in the cell supernatant were significantly decreased in the sophoridine + LPS group (P < 0.01). The rate of NF-kappaB entry the nucleus and TNF-alpha in the TLR4/MD-2 blocking agent + LPS group and the TLR4/MD-2 blocking agent + sophoridine + LPS group were notablly lower than that of the LPS model group (P < 0.01), close to that of the blank control group. However, there was no statistical significance between the two groups. CONCLUSION: TLR4/MD-2 may be one of sophoridine's targets. Sophordine's inhibitory effect on pathway activity of TLR4-NF-kappaB-TNF-alpha may be one of its antiendotoxin mechanisms.
