Objective To investigate the effects of macrophage inflammatory protein-1α (MIP-1α) combined with molecule 4-1BB L on the tumorigenicity of hepatocellular carcinoma cells in vivo. Methods Mouse MIP-1α (mMIP-1α) expressed Hepa 1-6 cells were transfected with m4-1BBL recombinant retrovirus, the anti-histidinol cells clones were selected and amplified. The expression of m4-1BB L was confirmed by flow cytometry. The growth curve of Hepa 1-6 cells transfected with mMIP-1α and m4-1BBL alone or together was drawn and compared. C57B/L Mice were randomly divided into 7 groups, 9 mice in each group, injected with mMIP-1α+m4-1BB L Hepa 1-6 cells, m4-1BB L Hepa 1-6 cells, mMIP-1α Hepa 1-6 cells, Hepa 1-6 cells, pLXSHD Hepa 1-6 cells or PBS respectively. The tumorigenicity of hepatocellular carcinoma cells and the mice survival rate were compared between each groups. Results Hepa 1-6 mMIP-1α+m4-1BB L cells which expressed both mMIP-1α and m4-1BB L were successfully established. The expression of mMIP-1α and m4-1BB L alone or together did not affect the growth curve of Hepa 1-6 cells. Observed for 5 weeks, no tumor developed in Hepa 1-6 mMIP-1α+m4-1BB L injected mice. The tumorigenicity of Hepa 1-6 mMIP-1α+m4-1BB L was lower than that of Hepa 1-6 mMIP-1α or Hepa 1-6 m4-1BB L in vivo. The survival rate of Hepa 1-6 mMIP-1α+m4-1BBL injected mice(9/9) was higher than that of Hepa 1-6 m4-1BB L injected mice (6/9)or Hepa 1-6 mMIP-1α injected mice (1/9). Conclusion Chemokine MIP-1α combined with costimulatory 4-1BB L lowered the tumorigenicity of hepatocellular carcinoma cells in vivo, and prolonged the mice survival period.

Background Dry eye syndrome is a frequent postoperative complication of laser in situ keratomileusis (LASIK).Some studies reported that the hinge location of corneal flap has influence on dry eye syndrome following LASIK,but others showed inverse views.Objective This systematic review was to evaluate and compare the effects of a superior-and nasal/temporal-hinge location on dry eye syndrome after LASIK.Methods A systematic literature retrieval was conducted in the Medline,Embase,Cochrane Library and CNKI from 1990 to 2011 according to designed searching strategy and relevant words.Published randomized-controlled clinical trial (RCT) data of the effect of superior-and nasal/temporal-hinge location on dry eye syndrome were extracted by two researchers separately.The outcome parameters,such as tear film breakup time (BUT),Schirmer Ⅰ test and corneal sensation were analyzed 1 week,3 months and 6-12 months postoperatively.The statistical analysis was performed using a RevMan 5.0 software and the quality of included literatures were graded according to the Jadad scale.Fixedeffect model was used for the inhomogeneity multiple studies (P≥0.1,homogeneity test I2 ＜50％),and random-effect model was used for the homogeneity studies.Results Ten pieces RCT papers were searched and 3 of them were rejected because of the lack of outcome data.In 7 included studies,652 eyes of 331 patients were involved in the Meta analysis,with the Jadad scores ≥ 3.BUT assessment was performed in 5 trials (530 eyes),Schirmer Ⅰ test evaluation was in 7 trials (652 eyes) and corneal sensation observation was in 4 trials (320 eyes),without significant homogeneity among the relevant literature(I2＜50％).Meta analysis revealed that BUT in the eyes with superior-hinge group was obvious shorter than that in the eyes nasal/temporal-hinge group at 1 week (WMD =-0.42,95％ CI:-0.79 to-0.06,P=0.020),but there was no signifieant difference in 3 months and 6-12 months duration postoperatively.Better corneal sensation was found at postoperative 3 months (WMD=-0.62,95％CI:-l.09 to-0.19,P=0.005) in the nasal/temporal-hinge group,but there was no difference in 1 week and 6-12 months duration postoperatively.No significant difference was seen between the two groups in Schirmer Ⅰ test during the follow-up period (P＞0.05).Conclusions LASIK with nasal/temporal-hinge corneal flap can improve the corneal sensation and relief the dry eye syndrome after LASIK to some extent.More high-quality evidence-based studies are still needed for the further clinical evaluation.

Background Nowadays,keratoplasty is widely used in the treatment of keratoconus.Deep lamellar keratoplasty(DLKP)is one of the research hotspots.However,its effacacy and safety are still concerned.Objective This paper was to evaluate and compare the therapeutic outcomes between DLKP and penetrating keratoplasty(PKP) for keratoconus.Methods The peer-reviewed and published literature was searched from PubMed database,Cochrane Library,EMBase and CNKI to identify relevant trails comparing DLKP with PKP for keratoconus.Methodological quality and Meta-analysis were carried out according to the principle of evidence-based medicine.The statistical analysis was performed using Review Manager 5.0 software.Results Eleven studies with 2950 eyes were identified that compared the results of DLKP and PKP procedures for keratoconus directly.Of those studies reporting vision and refractive data,less patients underwent DLKP achieved a best corrected visual acuity (BCVA)of≥0.5 than DLKP(RR=0.91,95％ CI:0.84-0.99,P=0.030) ;patients with DALK had severer myopia that those with PKP(RR =-0.60,95％ CI:-1.43-0.23,P =0.150),but the astigmatism was comparative (WMD =0.21,95％ CI:-0.48-0.91,P =0.550).Endothelial cell density values were higher in the DLKP group and the differences were significant.Endothelial immune graft rejection did not occur after DALK,and PKP had a higher overall graft rejection rate than DLKP(RR=0.06,95％ CI:0.01-0.31,P=0.001).Conclusions According to the available data,PKP can imporve the BCVA and refractive results,but DLKP can avoid the risk of endothelial rejection and reduce the risk of late endothelial failure for keratconus.

Background and purpose: Lysine specific demethylase 1(LSD1) is an important chromatin modifier. It epigenetically regulates gene expression pattern through chromatin modification and participates in maintenance of tumor malignant properties, such as oncogenesis, development, invasion, migration and metabolic transformation. SIRT3 (sirtuin 3) is a mitochondria localized tumor suppressor and regulates tumor metabolic transformation and oxidative stress. The correlation between LSD1 and SIRT3 has never been reported before. This study aimed to elucidate the correlation between LSD1 and SIRT3 with gene transcriptional regulation methods. Methods: RNA interference technique, co-immunoprecipitation assay(CoIP), chromatin immune-precipitation assay(ChIP) and ifrelfy luciferase activity assay were employed to elucidate the correlation between LSD1 and SIRT3 in pancreatic cancer. Results:mRNA and protein levels of SIRT3 were signiifcantly elevated in LSD1 knock-down PANC-1 cells. LSD1 interacts with PGC-1α, an important regulator of SIRT3 gene expression. LSD1 and PGC-1αoccupied the same region in SIRT3 promoter region through ChIP analysis. Luciferase activity assay validated LSD1 as a negative regulator of PGC-1αin SIRT3 gene transcriptional regulation. Conclusion:LSD1, as an important tumor promoter, negatively regulates the expression of tumor suppressor gene SIRT3, these results provide important clues for the role that LSD1 plays in aberrant metabolism and oxidative stress.

The objective of this study was to investigate the relationship between the expressions of breast cancer resistance protein (BCRP) gene and drug resistance as well as prognosis in adult patients with acute lymphocytic leukemia (ALL). Semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression of BCRP gene in 97 adult patients with acute lymphocytic leukemia (ALL) and 30 normal subjects. Beta(2) microglobulin (beta(2)-MG) was used as an internal reference. BCRP/beta(2)-MG ratio >or= 0.48 was defined as BCRP positive. The results showed that the positive ratio of BCRP gene expression in untreated group was 28.7%, in contrast that in refractory and relapsed patients was 51.2%. The first complete remission rates in patients with negative and positive expression were 71.7% and 29.7% respectively. In ALL subtypes BCRP gene expression of L3 type was distinctly higher than that of L(1), L(2) types. In immune types the BCRP gene expression of B-ALL was higher than that of T cell type, especially in mature B cell type with obviously statistical significance (p<0.01). It is concluded that the high expression of BCRP gene may induce clinical drug resistance, and may be an unfavorable factor for prognosis in adult patients with acute lymphocytic leukemia.
