RESUMEN
Objective:To discuss the influence of Tongfengning Capsule(TFN)in the rats with acute gouty arthritis,and to clarify the curative effect and mechanism of TFN in the acute gouty arthritis rats.Methods:The rat model of acute gouty arthritis was induced by injection of microcrystal sodium urate solution into articular cavity of the ankle joint.A total of 48 mice were divided into blank control group,model group,low(100 mg·kg-1),middle(200 mg·kg-1)and high(550 mg·kg-1)doses of TFN groups,colchicine(0.63 mg·kg-1)positive drug control group;8 rats in each group.The degrees of joint swelling of the rats were monitored at different time after modeling.The number of white blood cells(WBC),lymphocytes and neutrophils in the whole blood of the rats in various groups were detected,and the nitric oxide(NO)levels in the serum and homogenate as well as serum uricacid(UA)were detected.The levels of IL-1βand TNF-αin the soft tissue and synovial fluid around the ankle joint of the rats in various groups were measured.Results:Compared with model group,the swelling degrees of ankle joint of the rats in positive drug control group and high dose of TFN group were significantly decreased in 0-8 h(P<0.05 or P<0.01),especially in 4 h(P<0.01);but there were no significant differences in low and medium doses of TFN groups(P> 0.05).Compared with model group,the levels of WBC, lymphocytes and neutrophils in the blood of the rats in positive drug control group and TFN groups were decreased, especially in high dose of TFN group(P<0.05).The UA levels in serum of the rats in positive drug control group and high dose of TFN group were significantly lower than that in model group(P<0.05 or P<0.01),and the levels of serum NO was increased(P<0.05);but there were no significant differences in low and medium doses of TFN groups(P<0.05).The levels of NO,IL-1βand TNF-αin soft tissue and synovial fluid of the rats in positive drug control group and high dose of TFN group were significantly lower than those in model group(P<0.05 or P< 0.01);but there were no significant differences in low and medium doses of TFN groups(P<0.05). Conclusion:TFN has a remarkable effect in the treatment of gouty arthritis,and this effect may be associated with inhibiting the inflammatory reactions.
RESUMEN
A target molecule affinity-ultrafiltration liquid chromatography-electrospray ionization tandem mass spectrometric (LC-ESI-MSn) method was established for rapid screening acetylcholinesterase (AChE) inhibitors from total alkaloids of fibraurea recisa Pierre.A total of 12 potential inhibitors were screened from Fibraurea recisa Pierre.and 6 compounds were identified including palmatine,berberine,jatrorrhizine,palmatrubine,7,8-dihydro-8-hydroxyberberine and groenlandicine.The AChE inhibitory activity of these 6 compounds was validated in vitro.Palmatine showed the strongest inhibitory activity for AChE,which was stronger than that of donepezil hydrochloride,demonstrating the potential of palmatine as anti-Alzheimer's drug.This method is simple,rapid,and accurate for directly screening active ingredients which can inhibit AChE from complex extract of traditional Chinese medicines.

RESUMEN
AIM: To investigate the apoptosis and molecular mechanism of human hepatocellular carcinoma HepG2 cells induced by ginsenoside Rh4.METHODS: Human hepatocellular carcinoma HepG2 cells were treated with ginsenoside Rh4 at doses of 10, 20 and 40 μmol/L, and the inhibitory effect of ginsenoside Rh4 on HepG2 cell viability was measured by MTT assay.The apoptotic rate of HepG2 cells was analyzed by flow cytometry.The morphological changes of the HepG2 cells were observed by Hoechst 33258 and TUNEL staining.The expression of apoptosis-related proteins Bax, Bcl-2, caspase-3 and caspase-9 was determined by Western blot.RESULTS: Ginsenoside Rh4 promoted apoptosis of HepG2 cells in a dose-dependent manner.TUNEL and Hoechst 33258 staining showed that the cells appeared obvious shrinking, swelling and rupture after treated with ginsenoside Rh4 for 24 h.The results of Western blot showed that with the increasing concentrations of ginsenoside Rh4, the expression of pro-apoptotic proteins Bax, cleaved caspase-3 and caspase-9 increased, while anti-apoptotic protein Bcl-2 decreased gradually.CONCLUSION: Ginsenoside Rh4 induces apoptosis of human hepatocellular carcinoma HepG2 cells, and the main mechanism may be related to down-regulation of Bcl-2 and up-regulation of Bax, cleaved caspase-3, and caspase-9.
RESUMEN
objective:To investigate the relationship between magnetic resonance spectroscopy (MRS) metabolism and Ki-67 expres-sion in high-(HGG) and low-grade gliomas (LGG) by analyzing Ki-67 expression and HGG and LGG metabolites. Methods:We consid-ered 56 pathologically confirmed glioma cases in our hospital. The Ki-67 expression and the MRS metabolism parameters in the tu-mors were analyzed simultaneously. Results:The tumor solid value of Cho was positively correlated with the Ki-67 expression level (rs=0.714, P<0.05). By contrast, the Ki-67 expression level was negatively correlated with the tumor solid value of NAA (rs=?0.708, P<0.05) in 35 cases of the LGG group. The tumor solid value of Cho was also positively correlated with the Ki-67 expression level (rs=0.624, P<0.05). By comparison, the Ki-67 expression level was negatively correlated with the tumor solid value of NAA in the HGG group (rs=?0.769, P<0.05). Conclusion:The MRS metabolism was correlated with the Ki-67 expression in high-and low-grade gliomas.
RESUMEN
Objective:To investigate the correlation of the relative cerebral blood flow (rCBF) of three dimensional arterial spin labeling (3D ASL) with vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) in glioma. Methods:Fifty-three glio-ma patients confirmed by pathology were subjected to conventional, enhanced MR and 3D ASL imaging before operation to deter-mine VEGF expression and MVD levels in each patient. The correlations of rCBF with VEGF expression and MVD in glioma were evaluat-ed, respectively. Results:rCBF was noted to be positively correlated to VEGF expression and MVD in glioma. The rs were 0.728 (VEGF) and 0.620 (MVD), respectively (P<0.05). Conclusion:The positive correlation of rCBF with VEGF expression and MVD in glioma implied that 3D ASL is beneficial for evaluating microvessel angiogenesis in glioma prior to surgery. This finding is significant for developing clin-ical treatment plans and for assessing patient prognoses.
RESUMEN
Both ginseng and American ginseng can not be replanted on the same soil consecutively. The article reviews the development and progress of studies on the replant failure of ginseng and American ginseng with a special focus on allelopathy in recent years. The allelopathy effect in ginseng and American ginseng is reviewed from following aspects: collecting and extracting allelochemicals, effects of such allelochemicals on seeds germination, seedlings growth, antioxidant enzyme activities in ginseng roots, growth of ginseng pathogens and ginseng callus, and more. It is presumed that inhibitory allelopathy is one of the many possible factors contributing to the replant failure of ginseng and American ginseng. Based on that, the paper points out problems in current researches on the allelopathic effect of ginseng and American ginseng: the allelochemicals are consist of a mixture, which one plays the specific role is not clear; concentrating on a single allelochemical while ignoring the interaction among allelochemicals. It is suggested that further study for this area should be focused on the interactions among allelochemicals and interactions between allelochemicals and environmental impact factors. Another area of needed research is that of the migration and transformation of allelochemicals in soil and microbial involvement in allelopathy on the growth of ginseng and American ginseng.
