Acupuncture is a traditional empirical medicine, and evidence-based medicine(EBM) is a new medical method and development of the empirical medicine. Since 1990s, Chinese acupuncture workers began to absorb and use the methods and principles of EBM to guide acupuncture clinical research and practice. Now more and more domestic acupuncture clinicians use and follow the methods and principles of EBM. On the systemic review of acupuncture-associated articles in Cochrane library, previously effective acupuncture therapy lacks adequate evidences, which may be related to the low quality of randomized controlled trials(RCTs). In the future, only developing specialized team of acupuncture clinical research and clinical research center can radically elevate the levels of acupuncture clinical research and evaluation. Meanwhile, developing China's evidence-based acupuncture should base itself on the characteristics of acupuncture, such as emphasis on original research in ancient books,high-quality single RCTs and systemic review of non-randomized researches.

Objective To assess the influence of PBL formation study effectiveness of TCM students.Methods The controlled studies with the teaching format of both PBL and LBL were included to assess the effectiveness of learning,by searching CBM,CNKI and VIP database.All data was analyzed on Revman 5.1.Results 9 articles were included ; All were low in the quality of their methodology,and the theoretical scores of students in PBL or LBL format shows no statistical difference [SMD=3.76,95% CI ( -0.62,8.15 ) ].PBL format was superior to LBL on students' practical scores [SMD=7.62,95% CI ( 3.92,11.32 ) ]; Compared to LBL format,PBL proved to have a better influence on students' self-assessment for learning ability[OR=3.69,95% CI( 1.88,7.21 )].Conclusion PBL helps to enhance the activeness of students,to improve their practical ability,which is valuable if applied in clinical concerned courses.But the included studies were low in quality; more rigorously randomized controlled teaching trials are expected to verify the conclusion.

Aim TostudytheroleofASIC1aonthe matrix turnover and MAPK expression of the rat articu-lar chondrocytes with extracellular acidosis. Methods ArticularchondrocyteswereisolatedfromSprague-Dawley rats, and their phenotype was determined by toluidine blue and immunocytochemical staining. The GAG content of cell culture supernatant was deter-mined by dimethyl-methylene blue spectrophotometric assay, while Hyp content by chloramine T assay. ELISA assay was used to measure MMP-2 , TIMP-2 content. Furthermore, the ERK1/2, p38 MAPK phos-phorylation protein expression levels were tested by Westernblotassay.Results ASIC1acontributedto the effect of GAG, Hyp and TIMP-2 levels reduction induced by extracellular acidification, while the effect of MMP-2 was weaker. Moreover, ASIC1a could in-crease the ERK1/2 , p38 MAPK phosphorylation pro-teinexpressionlevels.Conclusion ASIC1acould regulate rat articular chondrocytes matrix turnover via ERK1/2 and p38 MAPK signaling pathway, and there-by inhibit the rat articular cartilage damage induced by acidosis.

Objective To study the expression and significance of acid-sensing ion channels(ASICs)in rat articular cartilage with adjuvant arthritis. Methods Complete Freund's adjuvant(CFA) was prepared by suspending heat-killed Bacillus Calmette Guerin(BCG) in liquid paraffin at 10 mg/ml. CFA-induced arthritis was developed by injection of 100 μl CFA emulsion intradermally into the right hind paw. The morphological changes of articular tissues was observed by light microscope; RT-PCR and immunoblotting analyses were used to detect ASICs in rat articular cartilage with adjuvant arthritis. Results RT-PCR and western blot showed that ASIC1a, ASIC2a and ASIC3 were present in the articular cartilage of normal and model group, the ASICs mRNA levels in the model group were higher than in the normal group detected by semiquantitative analysis (P<0.01), ASICs protein levels in model group were higher than those in the normal group (P<0.01) when examined by immunoblotting. Conclusion The results show that the expression of ASICs in AA articular cartilage is enhanced and it may be related with articular cartilage breakdown.

Aim To observe the anti-fibros is effect and mechanism of total flavones of Bidens bipinnata L(TFB) on immunological liver fibrosis in rats.Methods The pig serum was injected into abdominal cavity(0.5 ml,twice a week) for 12 weeks so as to induce hepatic fibrosis,and then the rats were treated with TFB daily for 10 weeks and killed at the 22 nd week.The HA,LN,PCⅢ and CⅣ in serum were assessed by ELISA.Liver samples collected after experiment were stained with hematoxylin-eosin(HE) staining,Masson staining and scored.The expression of ?-smooth muscle actin(?-SMA) in liver was analyzed by immunohistochemistry.The gene expression of TGF-?1 was detected by RT-PCR.Results Compared with model group,TFB treatment significantly reduced HA,LN,PCⅢ,CⅣ content in serum.Liver histology in the TFB treated rats was also improved.Moreover TFB could decrease the expression of protein ?-SMA and TGF-?1 mRNA.Conclusions TFB significantly reduced pig serum-induced liver fibrosis in rats,probably by decreasing the expression of TGF-?1 mRNA and then inhibiting the proliferation of HSC.

Aim To explore the therapeutic effect of total flavones of Bidens Bipinnata L (TFB) on liver fibrosis in rats and its mechanism. Methods The model of rat liver fibrosis was adopted which was induced by CCl4 injection. The effects of TFB were observed on the levels of serum HA,PCⅢ,CIV and Hyp in rats liver fibrosis,and on liver histopathological changes as well as collagen hyperplasia formation in liver tissue. The apoptosis of HSC were detected by double-staining of ?-smooth muscle actin (?-SMA) and TUNEL. The study in vitro was carried out on the culture of isolated hepatic stellate cells. Cell proliferation was detected with MTT assay. Cell apoptosis was detected by electron microscopy and flow cytometry. Results TFB can significantly reduce serum HA,PCⅢ,CⅣ and Hyp contents in liver fibrosis of rats,improve the liver pathologic injury,reduce collagen hyperplasia in liver of liver fibrosis rats,inhibit the activation and proliferation of HSC,and promote the apoptosis of HSC. In addition TFB could significantly inhibit the proliferation and increased the apoptosis of isolated and cultured HSC compared with the control group. Conclusions TFB has a significant therapeutic effect on the liver fibrosis rats,probably its inhibition of proliferation and stimulation of activated HSC apoptosis may be an important mechanism of its therapeutical effect against liver fibrosis.

Aim To explore the effect of 4-amino-2-trifluoromethyl-phenyl retinate(ATPR)on proliferation,differentiation activity in K562 cell line,and to research the mechanisms.Methods Cell proliferation was assessed by MTT assay.Cell differentiation index was analyzed by NBT reduction test.Morphologic changes were observed by Wright's staining in the light microscope. Cell cycle was determined by FCM.The mRNA expression of Cyclin D1,Cyclin E,CDK2,CDK4,CDK6,P21cip1,P27kip1,P57kip2,PCNA mRNA were detected by RT-PCR.While the protein expression of cyclin D1 and CDK4 was detected by Western blot.Results The growth of K562 cells was inhibited in a dose-dependent manner.NBT reduction test indicated that the ATPR could induce differentiation of K562 cells and increase the positive cell ratio.Morphologic changes were observed after Wright's staining using inverted phase contrast microscope.The proportion of cells in G0/G1 phase increased while S phase cells decreased.Cell cycle progression was blocked in the G1 phase.The expression of Cyclin E,cyclin D1,CDK2,CDK4,CDK6 mRNA decreased,while PCNA,P21 cip1,P27 kip1 change was not obvious,but P57 (kip2) mRNA expression was increased.Cyclin D1 and CDK4 protein expressions were reduced as well.Conclusions ATPR inhibits the growth of K562 cells and induces differentiation.P57 kip2 plays a key role in differentiation.Moreover,high level of P57kip2 is regulated via inhibiting its degradation through reducing proteasome-dependent proteolysis,and ATPR plays a role in cell cycle arrest.
