RESUMO
Objective To evaluate the relationship between long non-coding RNAs (LncRNA) in tumor tissues and clinico-pathological features of hepatocllular carcinoma (HCC).Methods Using hepatocellular carcinoma gene database GSE36376,we conducted a study on eight LncRNAs which are associated with liver diseases and analyzed the correlation between these LncRNAs and HCC clinico-pathological characteristics.We also evaluated the potential effect of LncRNAs on HCC development.Results H19 was overexpressed in non-tumorous tissues of HCC (P < 0.05),while MEG3,HOXA13,KCNQ1OT1 were all upregulated in tumorous tissues (all P < 0.05).HULC level in HCC tumorous tissues was negatively correlated with AJCC staging,BCLC staging and tumor size (all P < 0.05).UCA1 was positively correlated with BCLC staging (r =0.135,P < 0.05).Univariate analysis and multivariate logistic analyses showed that UCA1 was a risk factor of intrahepatic metastasis of HCC (OR =6.054,95% CI =1.429 ~ 25.642,P < 0.05); in contrast,HULC overexpression in tumorous tissues played a positive role in HCC tumor size (OR=0.805,95%CI=0.678 ~0.956,P<0.05).Conclusion HULC in tumorous tissues suppressed HCC proliferation,while UCA1 was a risk factor of HCC aggressiveness.
RESUMO
Objective To observe the protective effect of Xiaohuangdecotion against liver damage inα-naphthylisothiocyanate (ANIT)- induced cholestasis in rats and probe the potential mechanisms.Methods Male Wistar rats (40) were randomly divided into a normal group, a model group, aXiaohuangdecotion treatment group, and a UDCA control group (10 for each). Except for rats in the normal group, ANIT solution (6 ml/kg) was administered in other rats by gavages for cholestasis model. After ANIT treated 48 h, rats inXiaohuangdecotion group and UDCA group were treated withXiaohuangdecotion (1.73 g/kg) and UDCA (10 mg/kg) respectively for 1 week. And, rats in the normal group and the model group were given an equal volume of saline. At the end of the experiment, liver function rats were examined. Liver histology was examined by HE staining, and CD68 factor was tested by immunohistochemistry and Western blot.Results Compared with the model group, the content of ALT (164.6 ± 53.4 U/Lvs. 208.4 ± 28.5 U/L), AST (247.6 ± 76.1 U/Lvs. 341.8 ± 32.8 U/L), ALP (601.0 ± 101.1 U/Lvs. 720.6 ± 123.3 U/L), TBiL (96.5 ± 18.1μmol/Lvs. 149.6 ± 30.2μmol/L), DBiL (73.7 ± 16.6μmol/Lvs. 140.3 ± 28.6μmol/L) and TBA (93.4 ± 13.0μmol/Lvs. 146.5 ± 38.9μmol/L) were significantly reduced in the treatment group (P<0.01 orP<0.05). Compared with the model group, CD68 level (7.08 ± 0.19 vs. 17.42 ± 0.48)were significantly reduced by intervention ofXiaohuangdecotion (P<0.01).ConclusionsXiaohuangdecotion could improve liver functions and reduce CD68 expression, leading to a good hepatoprotective and jaundice-relieving effects.
RESUMO
Objective To evaluate the effects of pegylated interferon plus ribavirin on naive and retreated chronic hepatitis C (CHC) patients.Methods A total of 67 CHC patients were divided into naive group (n =35) and retreat group (n =32) based on their treatment history.And their virological responses [rapid virological response (RVR),early virological response (EVR),virological response to etravirine (ETR) and sustained virological response (SVR)] and risk factors were analyzed.Results ①RVR and EVR of naive group were 60% (n =21) and 77% (n =27),respectively,and the retreat group were 28% (n =9),53% (n =17).The differences between the two groups were significant (both P < 0.05).On the contrary,CHC patients in both groups might achieve similar ETR and SVR rates (P > 0.05) ; ② The relapse rate in the retreat group was higher than that in the naive group (22% vs.10%).But the differences had no statistical significance (P > 0.05) ; ③ CHC patients in the retreat group could achieve similar responses,including RVR,EVR,ETR and SVR (P > 0.05) whether treated previously with standard interferon or pegylated interferon; ④ According to muhivariable logistic regression analysis,the retreated genotype 1 CHC patients has a lower SVR rate compared with naive genotype non-1 counterparts (OR =0.29 and 0.26,all P < 0.05).Conclusions CHC patients in the naive group could achieve higher virological responses and a lower relapse rate compared to those in the retreat group.The previous treatment regimeu has no significant effect on virological responses of CHC patients retreated with Peg-IFN plus ribavirin.Genotype 1 and retreatment are both risk factors of achieving SVR.
RESUMO
Objective To identify a suspected Klebsiella variicola strain isolated from a patient with severe septic shock. Methods Sequences of rpoB, gyrA, mdh, infB, phoE and nifH genes were obtained from the clinical isolated suspected Klebsiella variicola strain, and used for constructing phylogenectic trees. Characteristics of phylogenetic trees were used to distinguish Klebsiella variicola from Klebsiella pneumoniae. Results All target gene sequences from this clinical isolated strain constantly formed a cluster with their counterparts from other Klebsiella variicola strains. These clusters were readily differentiated from Klebsiella pneumoniae clusters. Conclusions The clinical isolated strain belongs to Klebsiella variicola class and can cause septic shock. From genetic perspective, Klebsiella variicola is distinctly different from Klebsiella pneumoniae, most of which can be isolated from normal healthy people.
