OBJECTIVE: To observe the correlated serum inflammatory factor and cytokine changes in patients with coronary stent implantation, and to explore the significance of these changes.METHODS: Chinese Journal Full-Text Database was retrieved with search terms of coronary artery disease, percutaneous coronary interventions, inflammation, intimal hyperplasia, apoptosis and platelet-derived growth factor from 1995 to 2008. The language was restrained Chinese. A total of 17 literatures were collected, which concerns the changes of correlated inflammatory factor and cytokine levels and its significance. The literatures were sorted according to research object, experimental grouping,sample collection, assay method, experimental result, as well as experimental conclusion. Simultaneously, the patients received coronary stent implantation was analyzed to explore the significance of inflammatory factor and cytokine changes.RESULTS: The dynamic changed serum inflammatory factor and cytokine in patients with coronary stent implantation may be associated with the following mechanisms:①Endothelial cells were easily damaged in the balloon dilatation or stent implantation,therefore, inflammatory mediators or inflammatory factors were exposed to blood circulation, which stimulating neutrophilic granulocytes and up-regulating leukocyte adhesion molecule CD11b expression. ②Many stimulus could arise nuclear factor induced inflammatory reaction, produce interleukin 6, and stimulate C-reactive protein generation. ③The level of angiotensin Ⅱ increased at several days following stent implantation, and heightened with time prolonged, the proliferation of angiotensin Ⅱ was regulated by platelet-derived growth factor. By increasing the expression of endothelin, the synthesis of endothelin was accelerated, the proliferation and migration of vascular smooth muscle cells was promoted, which ultimately resulted in atherogenesis, balloon damage also involved in this process, which may be one of the mechanisms of restenosis.CONCLUSION: The changes of correlated inflammatory factor and cytokine can be served as inflammatory reaction indexes;moreover, soluble CD40 ligand, C-reactive protein and matrix metalloproteinase 9 may be associated with in-stent restenosis.

OBJECTIVE：To comp are cytotoxicity and anti-inflammatory effects of raw Aconitium kusnezoffii and A. kusnezoffii processed with Terminalia chebula . METHODS ：Using H 9c2 cardiomyocytes isolated from rat as subjects ，CCK-8 assay was used to detect the effects of 0.5，1，2，4，6，8，10 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on cell inhibition rate after cultured for 4，8，12，24 h. Hoechst 33258 staining was used to observe the effects on cell morphology characteristics after treated with 2，4，6 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula . Using macrophages RAW264.7 cells as subjects ，CCK-8 assay was used to detect the effects of 0.05，0.1，0.25，0.5，0.75，1，1.5，2 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on cell survival rate after cultured for 24 h. ELISA assay was used to detect the effects of 0.05，0.1，0.25，0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on the release of NO ， TNF-α and IL-6 in RAW 264.7 inflammation cells induced by LPS. RESULTS ：When the mass concentration was 0.5，1 mg/mL， neither raw A. kusnezoffii and A. kusnezoffii processed with T. chebula had no inhibitory effect on H 9c2 cells. When the mass concentration was 2 mg/mL，the inhibitory effects of A. kusnezoffii processed with T. chebula on H 9c2 cells was higher than that of raw A. kusnezoffii （P＜0.05 or P＜0.01）；fluorescence intensity of cells treated for 24 h was stronger than that of raw A. kusnezoffii，but its nucleus was intact. When the mass concentration was 4-10 mg/mL，the inhibitory rate of A. kusnezoffii processed with T. chebula on H 9c2 cells at different time points （except for 24 h culture of 8，10 mg/mL）was significantly lower than raw A. kusnezoffii （P＜0.05 or P＜0.01）. The characteristics of cell morphology also showed that the fluorescence intensity of raw A. kusnezoffii group at 4，6 mg/mL was stronger than that of A. kusnezoffii processed with T. chebula group，and the cell nucleus fragmentation was more serious in the raw A. kusnezoffii group. 0.05-0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula had no toxicity to RAW264.7 cells. 0.25，0.5 mg/mL raw A. kusnezoffii and 0.1，0.25，0.5 mg/mL A. kusnezoffii processed with T. chebula showed significant inhibitory effect on the release of NO ，0.05，0.1，0.25，0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula showed significant inhibitory effect on the release of TNF-α and IL-6 in RAW 264.7 cell（P＜0.05 or P＜ 0.01）. The inhibitory effects of A. kusnezoffii processed with T. chebula at the same concentration on the release of NO was better than that of raw A. kusnezoffii ，but poorer than raw A. kusnezoffii in the inhibitory effects on the release of TNF-α and IL-6. CONCLUSIONS：The toxicity of A. kusnezoffii can be reduced after processed with T. chebula ，especially the toxicity of it in medium or high concentration and short-term use is lower than that of raw A. kusnezoffii . At the same time ，the anti-inflammatory effect of A. kusnezoffii processed with T. chebula is comparable to that of raw A. kusnezoffii at the same concentration.

The antigenic characterizations and serological reactions of human liver flukes, Clonorchis sinensis and Opisthorchis viverrini, were analyzed by immunoblot. The antigenic profiles of the crude extract of Clonorchis contained major proteins of 8, 26-28, 34-37, 43, and 70 kDa, and those of Opisthorchis 34-37, 43, 70, and 100 kDa. Of these, the 8, 26-28 and 34-37 kDa bands of Clonorchis and the 100 kDa of Opisthorchis were major components of each excretory-secretory antigen. The 8 and 26-28 kDa bands were specific to Clonorchis but the 100 kDa of Opisthorchis cross-reacted with the sera of clonorchiasis, and the 34-37, 70 and 100 kDa bands cross-reacted with sera of other helminthiases. The frequency and intensity of the immunoblot reactions were positively correlated with the intensity of the liver fluke infection.

OBJECTIVE: To investigate the effect of Chinese herbal formula Ermiao Powder (, EMP) on the expression of cholinergic anti-inflammatory pathway in rats with rheumatoid arthritis (RA). METHODS: Seventy-two rats were randomly divided into 6 groups according to body weight, including normal control group, collageninduced arthritis (CIA) group, three doses EMP groups, and methotrexate (MTX) group (n=12 per group). All of the rats except for those in the normal control group were given multipoint subcutaneous injection of bovine type II collagen to establish a CIA model. Three EMP groups received a high- (4.5 g/kg), medium- (3.0 g/kg), and low- (1.5 g/kg) doses of EMP by intragavage, respectively. MTX group was injected intraperitoneally MTX at 0.9 mg/kg once a week as the positive control. The administration was 3 consecutive weeks. Joint swelling, arthritis index, and body weight changes in different experimental groups of rats were tested. The joint damage was evaluated by masson staining. Quantitative real-time polymerase chain reaction, Western blot, and immunohistochemistry (IHC) were performed to evaluate the expression of CHRNA7, encoding α7 nicotinic acetylcholine receptor in the cholinergic anti-inflammatory pathway, in different tissues and their localization in the spleen and joints. RESULTS: CHRNA7 expression levels were significantly higher in the joints and spleens of CIA group than those in normal control group (both P<0.05). Moreover, the CHRNA7 mRNA and protein levels in the spleen and joints of MTX and three doses of EMP groups were significantly lower than CIA group (all P<0.05). Compared with the MTX group, treatment with low-dose EMP resulted in significant reduction of CHRNA7 mRNA and protein expression levels (P<0.05 or P<0.01). IHC showed positive signals of CHRNA7 in the white pulp and red pulp of the spleens of rats; CHRNA7 was expressed on fibroblast-like synoviocytes, macrophages, and endothelial cells in the joints of rats, and the expression in the joints of low-dose EMP group was significantly lower than that in the CIA group (P<0.01). CONCLUSIONS Cholinergic anti-inflammatory pathway was involved in the generation of the inflammatory reaction in CIA rats, and EMP exerted therapeutic effect on RA through cholinergic anti-inflammatory pathway.

PURPOSE: To introduce the history and principle mechanism of electrochemical treatment (EChT) with animal study and report two cases successfully treated breast cancer and hemangioma by EChT. METHODS: In animal study, the breast cancer tumor in nude mouse treated with EChT (100 Coulomb/cm3) were reviewed for histologic changes. In the case studies, we reported method of EChT and clinical results after EChT. Case 1: 74 yr old female with locally advanced breast cancer received 3 times EChT with 1,000 Coulomb/time, 8 Volt. Case 2: 51 yr old female with breast hemagioma received one time EChT with 80 Coulomb, 8 Volt. RESULTS: In animal study, There were destructive change including vaculated cell fragment and extensive coagulative necrosis. Case 1 showed no local recurrence during 18 monthes after EChT. Case 2 also showed no evidence of recurrence of hemangioma. CONCLUSION: The EChT is easy to use. It is effective, safe, less traumatic and makes patients recover quickly. This is a new and effective method to treat patients with tumours that are inoperable and can not receive chemotherapy or radiotherapy.

OBJECTIVE： To compare low-polarity volatile constituents in supercritical CO2 extract from the roots and stem of Ilex asprella and its effects on the proliferation of IEC-6 in vitro， and to provide reference for making full use of wild resources of I. asprella and expanding its medicinal parts. METHODS： The low-polarity volatile constituents were extracted from the root and stem of I. asprella with supercritical fluid CO2 extraction（SFE-CO2）. The chemical constituents were analyzed by GC-MS. IEC-6 cells were treated with different concentrations of supercritical CO2 extracts （0， 1， 5， 10， 20， 40， 60， 80， 100 μg/mL） from roots or stems of I. asprella. MTT assay was used to detect the relative viability， and cell proliferation curve was drawn and EC50 of each extract were calculated. RESULTS： Sixty-two and forty-six low-polarity volatile constituents were identified from supercritical CO2 extract in the roots and stem of I. asprella with GC-MS； there were 24 common constituents totally， mainly including pelargonic acid（14.18％ and 6.14％），octanoic acid（10.59％ and 4.35％），hexanoic acid（8.63％ and 10.86％），paeonol（7.79％ and 6.00％），2-methyl-3-phenyl-propanal（6.3％ and 0.58％），acetic acid（1.72％ and 33.77％） in root and stem， respectively. The results of cell culture in vitro showed that when the concentration of supercritical CO2 extract from the roots and stems of I. asprella was lower （≤60 μg/mL）， it could significantly promote the proliferation of IEC-6 cells and their EC50 were 16.35， 20.20 μg/mL， respectively； when the concentration of the extract was higher （≥80 μg/mL）， it showed cytotoxicity and inhibited the proliferation of IEC-6 cells. CONCLUSIONS： There are similar species of volatile constituents in roots and stems of I. asprella and similar in vitro bioactivity of the supercritical CO2 extracts to IEC-6 cells. The short-chain fatty acids may be the active ingredient to promote cell proliferation， while paeonol may be the cytotoxic active ingredient.
