Objective:To establish a SPME-HPLC method for the determination of strychnine and brucine in Stryehnos nux-vomiea Linn. Methods:A novel capillary microtube monolithic column coupled with HPLC was prepared for the selective solid-phase microextraction of strychnine and brucine in Stryehnos nux-vomiea Linn. A Hypersil ODS column(150 mm × 4. 6 mm, 5 μm)was used and the mobile phase was acetonitrile- 0. 01 mol·L -1 sodium heptanesulfonate mixed with the same quantity of 0. 02 mol · L -1 potassium dihydrogen phosphate(adjusting pH to 2. 8 with 10% phosphoric acid)(21 ∶79). The detection wavelength was 260 nm,the sample size was 20 μl,and the column temperature was 25℃ . Results:The linear range of strychnine was 1. 2-90. 0μg·ml -1(r = 0. 999 8)and that of brucine was 1. 0-75. 0μg·ml -1(r = 0. 999 6). The average recovery was 100. 05%(RSD = 0. 58% ,n = 6)for strychnine and 99. 98%(RSD = 0. 27% ,n = 6)for brucine. Conclusion:The method is accurate and highly efficient,which can be used for the determination of strychnine and brucine in Stryehnos nux-vomiea Linn.

Objective To investigate whether the long non-coding RNA (lncRNA) metastasis associated lung adenocarcinoma transcript 1 (MALAT1) can act as a competitive endogenous RNA (ceRNA) to promote the migration of hepatocellular carcinoma (HCC) cells.Methods Transient transfection of small interfering RNA (siRNA) against MALAT1 was used to knockdown MALAT1 in HepG2 cells.Transwell assays were employed to assess the migration capabilities of HepG2 cells upon MALAT1 knockdown.RNA pull-down assays were performed to validate the direct binding between MALAT1 and miR-126*.Quantitative reverse transcription PCR (qRT-PCR) and Western blotting assays were used to detect the mRNA and protein levels of the miR-126* target genes.The dysregulation and prognostic significance of MALAT1 and miR-126* were analyzed in the public dataset of The Cancer Genome Atlas (TCGA).Results Compared with the control group, MALAT1 knockdown significantly inhibited the migration of HCC cells.MALAT1, with three miR-126* response elements, directly sponged miR-126* in a sequence-specific manner.The mRNA and protein levels of CXCL12, which was the miR-126* target gene, were significantly down-regulated upon MALAT1 knockdown.The TCGA database showed that MALAT1 was significantly up-regulated in HCC and high expression levels of MALAT1 were significantly associated with poor disease-free survival, whereas an opposite pattern of miR-126* was observed.Conclusion This study suggests that MALAT1 directly sponges miR-126* and upregulates the expression of CXCL12, which in turn promotes the migration of HCC cells.

It has been demonstrated that astrocyte elevated gene 1 ( AEG-1 ) can promote tumor initia-tion and progression .Over expression of AEG -1 is correlated with tumor angiogenesis ,metastasis and chemother-apy resistance of tumor cells of different origins .The present article is a review on the mechanism of AEG -1 me-diated drug resistance .Studies have shown that AEG -1 participates in carcinogenesis through Ha -ras,myc,NF-κB and PI3K/Akt signalling pathways .AEG-1 can also promote autophagy through activating AMP Kinase . Other researchers demonstrate that AEG -1 promotes MDR1 protein translation by up-regulating MDR1 mRNA expression ,and thus increases polyribosome .It is testified that AEG-1 can influence drug susceptibility and ex-pression of MDR gene as a RNA binding protein .Multiple functions of AEG -1 in drug resistance in multiple cancers demonstrate that AEG -1 can be used as a novel target for antitumor drugs .

AIM: To investigate the effect of a Chinese medicime, Dan-Shao-Hua-Xian capsule, on liver fibrosis induced by CCl_4 by observation of apoptosis and cell cycle variation in the liver cells. METHODS: Animal models were produced through eight-week treatment of the rats with CCl_4, alcohol and diet of high fat/low proteins, and then administration of Dan-Shao-Hua-Xian to the rats (1 g/kg) via stomach-tube-pouring for eight weeks was performed. Liver index, serum hyaluronic acid (HA) and glutamate pyruvate transaminase (ALT) were measured and hydroxyproline (Hyp) content in urine were determined. The extent of the liver fibrosis was observed under light microscope and apoptosis and cell cycle were also examined by cytometry between the two groups. RESULTS: Compared to the liver fibrosis group, the liver index, serum HA, ALT in the treatment group decreased, the development of liver fibrosis delayed, the urine Hyp and the number of apoptosed cells and the ratio of G_0/G_1 cells increased, as well as the S phase cells decreased, yet unable to return to normal. All those changes detected were statistically significant. CONCLUSIONS: The Dan-Shao-Hua-Xian is effective in treating the CCl_4-induced liver fibrosis in rats partly by virtue of inhibition of the growth of hepatic stellate cells and induction of apoptosis.
