Objective To investigate the expression of microRNA-224 in HepG2 cells and analyze its target genes to reveal its role in the carcinogenesis of hepatoma. Methods The genes with differential expression in HepG2 cells and LO2 cells were obtained by gene expression microarray analysis. The up-regulated target genes of microRNA-224 were predicted by bioinformatics method, and their functions were analyzed. Results Compared with LO2 cells, microRNA-224 was highly expressed in HepG2 cells. A total of 264 target genes of microRNA-224 were predicted, including genes involved in cell cycle, signal transduction, cell differentiation, proliferation and apoptosis. Conclusions MicroRNA-224 is highly expressed in HepG2 cells. MicroRNA-224 plays an important role in the carcinogenesis of hepatoma via regulating the expression of its target genes directly or indirectly.

0.05).The 2 -year and 3-year survival rates were 91.7 %,89.2 % and 85.8%,86.1% in all patients for either gr oup. The 2 -year and 3-year survival rates were 84.2%,81.8% and 72.9%,77.1% in p atients with positive axillary lymph nodes for the two groups, with the differen ces insignificant (Logrank test P=0.663, P=0.9 19).There were no differences in the 2-year and 3-year survivals for patients with stage Ⅲ and over receiving ch est wall irradiation or not and patients who received different doses of chest w all irradiation (Logrank test P=0.449, P=0.764 ). Conclusions Locoregional recu rrence is not reduced and survival rate is not improved by chest wall irradiatio n in this study. The prognostic impact of chest wall irradiation and the optimal target of radiotherapy remains to be substantiated by more randomized trials.

The 1H-NMR fingerprints of three different species tibetan medicine sea buckthorn were established by 1H-HMR metabolomics to find out different motablism which could provide a new method for the quality evaluation of sea buckthorn. The obtained free induction decay (FID) signal will be imported into MestReNova software and into divide segments. The data will be normalized and processed by principal component analysis and.partial least squares discriminant analysis to perform pattern recognition. The results showed that 25 metabolites belonging to different chemical types were detected from sea buckthorn,including flavonoids, triterpenoids, amino acids, carbohydrates, fatty acids, etc. PCA and PLS-DA analysis showed three different varietiest of sea buckthorn that can be clearly separated by the content of L-quebrachitol, malic acid and some unidentified sugars, which can be used as the differences metabolites of three species of sea buckthorn. 1H-NMR-based metabonomies method had a holistic characteristic with sample preparation and handling. The results of this study can offer an important reference for the species identification and quality control of sea buckthorn.

This study performed phylogenic analysis on a dengue strain isolated from an outbreak of dengue fever in 2009 at Yiwu City of Zhejiang Province,China,and further to analyze the immunogenicity of E protein of this viral isolate.Firstly,the viral genome was amplified by RT-PCR and phylogenetic trees were constructed by MEGA 4 based on both nucleotide and amino acid sequences of E and NS1 proteins.The phylogenetic analysis showed that the similarity of Yiwu strain with the Guangzhou GZ1D3 strain and the India GWL-25 strain was over 99％.Secondly,the expression plasmid of E protein was constructed and transfected into 293T cells.The secreted E protein were then purified by sucrose density gradient centrifugation and used to inoculate BALB/c mice.The humoral immunity was evaluated by ELISA and neutralizing antibody analysis.Resuits showed that the E protein of Yiwu strain could induce dengue specific IgG antibodies and neutralizing antibodies.Therefore,the study found that the Yiwu strain was classified into the subtype Ⅲ of dengue virus type 3 (DENV-3),and the E protein of this strain had strong immunogenicity

Objective To develop a candidate reference method for the measurement of progesterone in human serum.Methods The serum sample is mixed with the internal standard [3,4-~(13)C_2] progesterone.After extraction with n-hexane and purified by a aqueous solution of 2-Hydroxypropyl-?- cyclodextrin (HP-?-CD),the serum progesterone and labeled progesterone are converted to the 3-enol heptafluorobutyrate and analyzed by gas chromatography mass spectrometry (GC/MS) with selected ion monitoring.The concentration of serum progesterone is calculated by bracketing method.Results The results gave coefficients of variation (CVs) of 0.69% to 2.12%.The analytical recoveries ranged from 98.3% to 100.1%.The results of measuring certified reference materials of serum progesterone are agree with the target value.Conclusion The procedure for measuring progesterone in serum is a highly accurate and precise method and may be used as a candidate reference method for serum progesterone assays.

Objective Application of the second metatarpophalangeal joint by traction prolong trans- plant repair the defects in the metacarpophalangeal joint,reconstruct the function of it.Methods By means of the apparatus to prolong finger in advance,then transplant the second metatarpophalangeal joint to recon- struct metacarpophalangeal joint for seven cases of obsolete defects in the metacarpophalangeal joint.Results The average of finger prolong was 2.6 cm,consultation from 1 to 4 years.average 2.5 years,thai the trans- plant joints have all survived and osteal concrescence.Through the criterion Chinese Medical Association,good rate was 85.7%. Conclusion It' s a good method to repair obsolete defects in the metacarpophalangeal joint by transplant traction prolong of the second metatarpophalangeal joint.

Objective To investigate and compare the different effects of soluble adult wornl antigen(SWA)and soluble egg antigen(SEA)of Schistosoma japonicum on the apoptosis and cell-cycle of routine CD4~+T cells.Methods Purified CD4~+T ceUs from normal C57BL/6 mice were cultured with CFSE labeled antigen presenting clls in the presence of different stimuli for 36 h.Flow cytometry(FCM)was used to detect the apoptosis of CD4~+T cells by fluorescence conjugated caspase-3 antibodie staining.The flow cytometry was used to analyze the cell-cycle of CD4~+T cells cultured as described above for 96 h by propidium iodide staining.Results Compared with the apoptosis percentage of CD4~+T cells[(1.24±0.29)%]in the SEA stimulated group,that in the SWA stimulated group[(1.52±0.38)%]did not show statistically significant difference(P>0.05).Compared with the cell percentages in G1 phase[(78.91±2.98)%],S phase[(7.39±0.85)%]and G2/M phase[(10.69±1.05)%] in the SWA stimulated group,that of the G1 phase[(59.42±1.32)%]was significantly lower,but those in the S phase[(21.07±O.88)%] and G2/M phase[(18.88±1.21)%]were significantly increased in the SEA stimulated group(P<0.01).Conclusions There is no statistically significant difference between the apoptosis levels of CD4~+T ceHs stimulated by SWA and SEA.However,SEA significantly promotes the progression of the cell-cycle of CD4~+T cells compared with SWA.
