Objective To investigate the expression and biological significance of microRNA-126 in colon cancer tissue.Methods The expression of microRNA-126 in colon cancer tissues and adjacent tissues of colon cancer patients was detected by real-time quantitative polymerase chain reaction (RT-PCR) in 104 patients with colon cancer surgery (total of 104 pairs).The lentiviral vector was used to construct microRNA-126 cell line,and the effects of microRNA-126 on proliferation,migration and invasion of colon cancer cells were further studied in vitro.Results The relative expression of microRNA-126 in colon cancer tissues (0.63±0.11) was significantly lower than that in adjacent tissues (1.08±0.15),the difference was statistically significant(t=14.561,P＜0.01).The positive rate of microRNA-126 expression in colon cancer tissues (61.5％) was significantly lower than that in adjacent cancer tissues (86.5 ％) the difference was statistically significant(x2=16.908,P＜0.05).The expression of microRNA-126 was significantly correlated with Dukes stage,depth of invasion,lymph node metastasis and distant metastasis (P＜0.05).In the Transwell experiment with matrix glue,the number of cell migration in transfection group (11.26±4.85) was significantly lower than that in blank control group (264.37±32.15),the difference was statistically significant (t=23.418,P＜0.01).In the Transwell experiment without matrix glue,the number of cell migration in transfection group (83.75 ± 13.74) was significantly lower than that in blank control group (339.64 ± 26.38),the difference was statistically significant(t=12.682,P＜0.01).MicroRNA-126 could inhibit the proliferation and invasion of SW480 cells.Conclusion MicroRNA-126 can significantly inhibit the development of colon cancer cells and affect the biological behavior of colon cancer cells.

Objective To explore the treatment of hemangioma associated with thrombopenia(Kasabach-Merritte syndrome,KMS) in infant.Methods The clinical manifestation and the therapy of 14 cases patients with KMS in hospital from 2003 to 2006 were collected ang analyzed,the 400 g/L urea(manufactured by ourself)combined with methylprednisolone local injection were used and followed 0.5 to 1.0 year.Results Two in 14 cases were emergency exairesis,7 cases were recurred for several times,12 cases were cured,1 case was improved,1 case was loss the connection.Conclusions It is an ideal therapy method to use the urea combined with glucocorticoid to treat infancy KMS,little trauma,definite effective,low side effect,high cure rate.

SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

Objective The aim of this trial is to compare the efficacy and safety between national-made and imported ablation catheters for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT). Method A total of 1342 patients with AVNRV or AVRT were randomly treated with national-mode ablation catheter (Group 1, n = 672) or imported ablation catheter (Group 2, n=670). Results The immediate ablation success rate was similar in Group 1 and Group 2 (97.9% vs. 99.1%, P > 0.05). There were also no significant differences in the procedure time [(68±36) min vs. (67±34 ) min], the fluoroscopic time [(14±14) min vs. (10±11) min], the number of energy delivery [(4.5±4.5) beats vs. (4.6±3.9) beats], the ablation time [(260±218) s vs. (257±207) s] and the score of ablation catheter performance evaluation[(4.4±0.5) vs. (4.5±0.4)] between the two groups (all P > 0.05). Three patients developed pericardial effusion (1 in Croup 1 and 2 in Group 2, P>0.05). Incidence of recurrence of tachycardia during the 3 months follow up was similar between the 2 groups (14 in Group1 vs. 16 in Group 2, P > 0.05). Conclusion National-made and imported radiofrequency ablation catheters have similar efficacy and safety for treatment of AVNRT and AVRT.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.

Adipose-derived stem cells (ASCs) induce therapeutic angiogenesis due to pro-angiogenic cytokines secretion.Superparamagnetic iron oxide (SPIO) nanoparticles are critical for magnetic resonance (MR) tracking of implanted cells.Hypoxia is a powerful stimulus for angiogenic activity of ASCs.In this study,we investigated whether therapeutic potency could be enhanced by implantation of hypoxia-preconditioned SPIO-labeled ASCs (SPIOASCs) into the infarcted myocardium.ASCs and SPIOASCs were cultured under 2％ O2 (hypoxia) or 95％ air (normoxia).Cells were intramyocardially injected into the infarcted myocardium after 48-h culture.We found that hypoxia culture increased the mRNA expression of hypoxia-inducible factor-1 alpha (HIF-lαt) and vascular endothelial growth factor (VEGF) in ASCs and SPIOASCs.The VEGF protein in the conditioned medium was significantly higher in hypoxic ASCs and SPIOASCs than in normoxic ASCs and SPIOASCs.The capillary density and left ventricular contractile function in the infarcted myocardium were significantly higher 4 weeks after implantation with hypoxic ASCs and SPIOASCs than with normoxic ASCs and SPIOASCs.Improvement in the capillary density and left ventricle function didn't differ between hypoxic ASCs-transplanted rats and hypoxic SPIOASCs-transplanted rats.Hypoxic culture enhanced the angiogenic efficiency of ASCs.It was concluded that implantation of hypoxic ASCs or SPIOASCs promotes therapeutic angiogenesis and cardiac function recovery in the infarcted myocardium.SPIO labeling does not impact the beneficial effect of hypoxic ASCs.

Objective To investigate the influence of anti-depression therapy on cardiac function and short-term prognosis in elderly patients with congestive heart failure (CHF) and the safety and effectiveness of fluoxetine in these patients.Methods Ninety six elderly hospitalized patients with CHF accompanied with depressive disorder were randomly divided into two groups:fluoxetine (20mg once daily)and placebo treated groups based on the routine cardiac drug therapy for 3 months. Results The prevalence rate of depressive disorder in elderly patients with CHF was 31.1%.The length of stay of fluoxetine group was shorter than that of placebo group.The post-treatment depressive exponents of self-rating depression scale(SDS)in fluoxetine group (51.39%?8.63)was lower than those in pretreatment and in placebo group.The improvement of cardiac function in fluoxetine group(53.4%?4.5%) was much better than that of placebo group (P
