Objective: To study the factors affecting the content of magnolol which is one of the main active components in Magnolia Bark Three Agents Decoction. Methods: The contents of magnolol in extracts of Magnalia Bark Three Agents Decoction (medicinal materids were decocted alone, together or in different compatibleness, and residuals) were determined by HPLC. The effects of use amount of Radix et Rhizoma Rhei and Fructus Aurantii Immaturus, decoction time, and extraction times on magnolol content were studied by orthogonal design.Results: The content of magnolol in Magnolia Bark Three Agents Decoction of which medicinal materials were decocted together was over double that of which they were decocted alone. The dissolution sate of magnolol increased with the increasing of the use amount of Fructus Aurantii Immaturus and extraction times. Conclusion: Fructus Aurantii Immaturuns and extraction times are the main factors affecting magnolol content in Magnolia Bark Three Agents Decoction.

AIM: To evaluate its pharmacodynamic effects of zhi-chuan-ling (ZCL) oral liquor, a traditional Chinese medicinal prescription, on asthma. METHODS: Asthma models of guinea pigs were established by aerosol inhalation of mixed solution of histamine and acetylcholine for the observation of effects of ZCL on the latent period of asthma attack. Some other indices were also investigated including the contraction of smooth muscle strips isolated from the trachea or intestinum ileum, and variations of the tracheal volume and the bronchotracheal perfusion in guinea pigs. RESULTS: ZCL elongated the latent period of asthma attack induced by areol inhalation of mixed solution of histamine and acetylcholine, antagonized activities against the contraction of the trachea and intestinum ileum induced by histamine or acetlcholine, and increased the tracheal volume and the bronchotracheal perfusion in ginea pigs in vitro. CONCLUTION: ZCL can reduce airway hyperresponsibility, relax bronchospasm, remit ventilation disturbance, and improve ventilatory function by its biologic activities against acetlcholin and histamine.

This study was aimed to establish a fast determination method of main components in honey. Honey samples from difference production bases were used as study objects. Transmission and reflection spectra of different honey samples were collected with the Fourier transform near infrared spectrometer. The main components in honey (moisture content, fructose content, glucose content and reducing sugar content) were detected by the near infrared quantitative analysis technique. The near infrared quantitative analysis models of moisture content, fructose content, glucose content and reducing sugar content in honey were established by the partial least squares (PLS). The results showed that the correlation coefficient (r) of the moisture content, fructose content, glucose content and reducing sugar content in honey were 0.997 25, 0.973 90, 0.927 94 and 0.952 68, respectively. The root mean square error of prediction (RMSEP) were 0.165 (%), 0.564 (%), 1.300 (%) and 1.270 (%), respectively. It was concluded that determination of main components in honey by the near-infrared spectroscopy technology was a fast and nondestructive determination method with high accuracy, which can be used in the quantitative detection of main components in honey.

Objective: To investigate the effects of different processing methods (steeping, boiling) and different adjuvants (alum, ginger, bile) on toxicity and adverse effect of Arisaema Amurense Maxim. Methods: The determinations of toxicity and adverse effect were performed by tasting of hot and tingle, test of stimulating rabbit eyes and acute toxicity test. Results: The product processed by alum is better than that by ginger in eliminating hot and tingle taste. The product processed by heating is better than that without heating. The test result of stimulating rabbit eyes is similar to that of hot and tingle taste. The result of acute toxicity test indicates that the toxicity of Arisaema Amurense Maxim is low. Conclusions: It is scientific that Arisaema Amurense Maxim. is mostly processed by alum and heat. The clinical application of Arisaema Amurense Maxim. has a certain safety.

Objective To determine the association between weight gain induced by atypical antipsychotic and the polymorphisms of MC4R gene rs12970134.Methods 62 patients who had weight gain more than 7% of their pre -drug body weight were selected as study group,and 62 patients who had weight gain less than 7% of their pre -drug body weight were selected as control group.The polymorphism of MC4R gene rs12970134 was analyzed by using polymerase chain reaction and directly sequencing technology.Results There were no significant differences in the frequency of MC4R gene rs12970134 genotypes and alleles between the two groups(χ2 =0.648,P =0.723;χ2 =0.679,P =0.410).While after the treatment with atypical antipsychotic,the weight gain degree in patients with GG genotypes was less than patients with GA /AA genotypes[(22.18 ±0.33)kg/m2 vs.(23.53 ±0.58)kg/m2 ](t =-2.167,P =0.032).Conclusion The polymorphisms of MC4R gene rs12970134 maybe affect the weight gain degree in patients after treatment with antipsychotic.

Objective:To investigate the anti-myeloma cells specific immune activity induced by myeloma protein-pusled dendritic cells(DCs).Methods: DCs were obtained from peripheral blood(PB) of multiple myeloma(MM) patients after co-culture with GM-CSF,IL-4 and TNF-?.The phenotype of DCs was examined by flow cytometry.Host lymphocytes were stimulated with DCs pulsed with myeloma protein acquired from serum of MM patients on DEAE-celluose;lymphocytes treated with unpulsed-DC served as control.[~(3)H]-thymidine incorporation and 4 h ~(51)Cr-release assay were used to detect the proliferation and cytotoxicity against different targets(auto-myeloma cells,U266 cells) by T lymphocytes.Results: In vitro proliferation and cytotoxicity of T lymphocytes activated by myeloma protein pulsed-DCs were greater than those of T lymphocytes in the control group(P
