ObjectiveTo investigate the therapeutic effects and difference in the effects of Arisaematis Rhizoma （AR） before and after processing （i.e.， Arisaematis Rhizoma Preparatum， ARP） with Zingiberis Rhizoma Recens-Alumen on allergic asthma in rats and to provide a basis for the theory of processing improving the efficacy. MethodA rat model of allergic asthma was established in 70 SD rats by intraperitoneal injection of ovalbumin （OVA）-aluminum hydroxide. The rats were administrated with the aqueous extracts of AR （1.2， 0.3 g∙kg^-1） and ARP （1.2， 0.3 g∙kg^-1） aqueous extracts by gavage， and montelukast sodium （0.001 g∙kg^-1） was used as the positive drug. The T helper cell type 1/type 2 （Th1/Th2） ratio in the serum and bronchoalveolar lavage fluid （BALF） and percentages of inflammatory cells in BALF were determined. Polymerase chain reaction （PCR） was employed to determine the mRNA level of mucin 5AC （MUC5AC） in the lung tissue. The pathological changes in the lung tissue were observed by hematoxylin-eosin （HE） staining and PAS staining. Immunohistochemical assay was employed to measure the expression of c-Jun amino-terminal kinase （JNK）， extracellular signal regulated protein kinase （ERK）， and p38 mitogen-activated protein kinase （p38 MAPK） in rat lung tissue. Western blot was employed to determine the protein levels of ERK， p-ERK， JNK， p-JNK， p38， p-p38 in the lung tissue. The effects of AR and ARP were compared based on overall desirability. ResultCompared with the blank group， the levels of interleukin-12 （IL-12） and γ interferon （IFN-γ） in serum and BALF of rats in the model group were significantly lower （P<0.05， P<0.01）， and the levels of interleukin-4 （IL-4）， interleukin-5 （IL-5） and interleukin-13 （IL-13） were significantly higher （P<0.05， P<0.01）. Compared with the model group， the serum and BALF contents of IL-12 and IFN-γ in rats in the montelukast sodium group， high-dose AR group and high-dose ARP group were significantly higher （P<0.05， P<0.01）， and the contents of IL-4， IL-5 and IL-13 were significantly lower （P<0.05， P<0.01）， and the serum contents of IFN-γ in rats in the low-dose AR group and low-dose ARP group were in BALF was significantly higher （P<0.05） and IL-4 and IL-13 were significantly lower （P<0.05， P<0.01）， the percentages of macrophages， lymphocytes， neutrophils， and eosinophils were reduced in BALF， and the expression of JNK/ERK/p38 MAPK signaling pathway and MUC5AC protein was inhibited in lung tissues. Overall assessment of the normalized analysis revealed that the ARP group was slightly more potent than the AR group after administration of the same dose. ConclusionAR and ARP can effectively treat allergic asthma by inhibiting JNK/ERK/p38 MAPK signaling pathway， and the effect is better after concoction， which can provide data support for its "concoction efficiency".

Objective: To compare the anti-inflammatory effect of Fraxini Cortex pieces between integrated production process and traditional processing method. Methods: The model of rat paw swelling induced by carrageenan was used to study the anti-inflammatory and swelling reliving effects of water extracts of Cortex Fraxini with different methods. The main chemical components of the 2 kinds of Cortex Fraxini herbal pieces were determined by high performance liquid phase. Results: Compared with the blank group, the water extracts of the 2 kinds of Cortex Fraxini could reduce the swelling of the rats and improve the various indicators of inflammation. However, the anti-inflammatory and swelling reliving effects of the integrated processing of Cortex Fraxini were more significant. The contents of 4 main active ingredients of esculine, fraxin, aesculetin and fraxetin in the integrated processing of Cortex Fraxini were higher than that of the traditionally processed Cortex Fraxini. The total amount of 4 kinds of coumarins in the integrated Cortex Fraxini was about 1.5 times that of the traditionally processed water extract of Cortex Fraxini. Conclusion: The integrated processing and traditional processing of Cortex Fraxini have similar effects on anti-inflammatory effects, and have the superiority of reducing the loss of active ingredients, which is worthy of popularization and application.

Objective: To observe the effect of warm needling therapy plus acupuncture on third lumbar vertebra transverse process syndrome.
Methods: Sixty cases of third lumbar vertebra transverseprocess syndrome were randomly divided into a warm needling groupor an acupuncture group, 30 cases in each group. Cases in the acupuncture group were treated by routine points and needle sticking manipulation, while those in the warm needling group were treated by moxibustion plus needling as same as the acupuncture group. Japanese orthopedic association scores (JOA) in the two groups were observed and compared after 2 treatment courses.
Results: After treatment, the JOA score in the warm needling group was higher than that in the acupuncture group (P<0.01); subjective symptom, clinical syndromes, activity of daily living (ADL) in the warm needling group were all higher than those in the acupuncture group (allP<0.05); the score of pain in the warm needling group was significantly lower than that in the acupuncture group (P<0.01); the total effective rate in the warm needling group was 76.7%, versus 70.0% in the acupuncture group, showing a statistically significant difference (P<0.05).
Conclusion: Warm needling therapy is more effective thannormal acupuncture in treating third lumbar vertebra transverseprocess syndrome.

BACKGROUND:A novel biodegradable Mg-Zn alloy has been designed,in which the density and the Young's modulus are proximal to human bone,at the same time,it depletes the toxicity of aluminium and rare earth element in commercial magnesium alloys.OBJECTIVE:To evaluate the cytocompatibility of biodegradable Mg-Zn alloy.DESIGN,TIME AND SETTING:Contrast study was performed in the central laboratory of the Sixth People's Hospital of Shanghai Jiao Tong University between November 2007 and March 2008.MATERIALS:The Mg-6wt%Zn was prepared by School of Materials Science and Engineering of Shanghai Jiao Tong University,with the density was 1.82 g/cm3 and the Young's modulus was 44 GPa.L-929 cells for cytocompatibility test were provided by Chinese Academy of Science Type Culture Collection.Ten male New Zealand rabbits were employed in the hemolysis test.METHODS:The Mg-Zn alloy extraction medium was prepared by serial dilutions with fresh medium to 10%,50% and 100%.The experiments were carried out in a 96-well tissue-culture plate.Simple DMEM culture solution was taken as negative controls,while DMEM culture solution supplemented with 0.64% phenol served as positive controls.MAIN OUTCOME MEASURES:Relative proliferation rate of L-929 cells was determined at 2,4 and 7 days with MTT assay.The cytotoxicity of Mg-Zn alloy was evaluated according to ISO 10993-5:1999.The L-929 cell morphology and growth at 2,4 and 7 days were determined under inverted microscope.Based on ISO 10993-4:2002,hemolysis in vitro was evaluated through measuring erythrocyte lysis and ferrohemoglobin freeing degree with indirect contact method.RESULTS:The number of L-929 cells increased significantly and the morphology was not changed.The growth and morphology of cells in different Mg-Zn extraction medium had no difference from negative control group.Cytotoxicity test showed that biodegradable Mg-Zn alloy did not have obvious toxicity on L-929 cells,and the cytotoxicity of these extracts was in grade 0-1.Hemolysis test suggested that the Mg-Zn alloys did not have obvious hemolysis reaction,and the hemolysis index was 3.4%,which was less than the national standard (5%).CONCLUSION:The Mg-Zn alloys do not have obvious cytotoxicity and hemolysis reaction,which demonstrate that Mg-Zn alloys have good cytocompatibility.
