OBJECTIVETo investigate the expression of microRNA-10a-5p (miR-10a) in laryngeal epithelial premalignant lesions (LEPL) and to analyze the correlations of its dysregulation with clinicopathologic parameters of LEPL.

METHODSAccording to the WHO classification (2005), 94 cases of LEPL were grouped into mild dysplasia (MID), moderate dysplasia (MOD), severe dysplasia (SD) and carcinoma in situ ( CIS). The expression of miR-10a in 94 cases of LEPL was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and correlated with the clinical and follow-up data of all LEPL patients.

RESULTSmiR-10a was down-regulated in LEPL with increasing grade of dysplasia. There was significantly statistical difference between low-risk ( MID + MOD) and high-risk ( SD + CIS) lesion groups (P = 0.03). The linear regression analysis showed that miR-10a was correlated with grade and gender of LEPL (P < 0.05).

CONCLUSIONSDown regulation of miR-10a may be a useful molecular marker for grading of LEPL and diagnosis of early laryngeal cancer.

We isolated 30 Trichomonas vaginalis for the PCR detection from the gynecological outpatients in the Affiliated Hospital of Zhengzhou University using the specific 16s rDNA primers of Mycoplasma hominis. The results showed that there were 25 cases of Mycoplasma hominis infection, with the infection rate of 83.33%. This gave a clew that the symbiosis of Trichomonas vaginalis with Mycoplasma hominis may be of certain generality in China. We sequenced the ferredoxin gene of 10 Trichomonas vaginalis where 5 Mycoplasma hominis were positive and five negative, and found that the ferredoxin (Fd) gene of the 10 Trichomonas vaginalis were exactly the same. But compared to the genes in the GenBank, a comparative analysis of the gene revealed that there were 3 more ctg bases at the 200th position of encoding leucine, but this did not lead to changes in reading frame. The gene homology was 99%.

Objective To evaluate effects of acitretin and interferon?α(INF?α)alone or in combination on the proliferative activity of and interleukin?15 expression in human cutaneous T?cell lymphoma Hut78 cells. Methods Cultured Hut78 cells were divided into several groups, including blank control group, negative control group, dimethyl sulphoxide (DMSO) group and experimental groups. Cells in experimental groups were additionally classified into several subgroups to be treated with acitretin(0.1-10μmol/L, acitretin groups)or INF?α(5 000-20 000 IU/ml, INF?αgroups) alone, or the combination of 1.0 μmol/L acitretin and IFN?α at concentrations of 5 000- 20 000 IU/ml (combination groups), for 24, 48 and 72 hours. Subsequently, cell counting kit 8(CCK8)assay was performed to assess the proliferative activity of Hut78 cells, and enzyme?linked immunosorbent assay(ELISA)to measure the expression of IL?15 in these cells. Results The proliferative activity of and IL?15 expression in Hut78 cells were both obviously suppressed in the acitretin groups and combination groups compared with the DMSO group, as well as in the INF?αgroups compared with the negative control group, and the inhibitory effects gradually increased with the increase in acitretin or INF?αconcentrations and treatment durations. As repeated measures analysis of variance revealed, there was a significant difference in both proliferation inhibition rates and IL?15 expression among different treatment durations and among different concentrations of acitretin or INF?α(all P<0.05), and there was an interaction effect between treatment durations and drug concentrations(all P<0.05). A significant difference was observed in both proliferation inhibition rates and IL?15 expression at 24, 48 and 72 hours when the 1.0?μmol/L acitretin+ 10 000/20 000?IU/ml IFN?αgroup was compared with the 1.0?μmol/L acitretin group and 10 000/20 000 IU/ml IFN?αgroup(all P<0.05). There was also a significant difference in IL?15 expression at 24, 48 and 72 hours between the 1.0?μmol/L acitretin+50 000?IU/ml IFN?αgroup and 5 000?IU/ml IFN?αgroup(all P<0.05). Conclusions Acitretin and IFN?αboth can inhibit the proliferation of and IL?15 expression in Hut78 cells, the inhibitory effects are enhanced with the increase in drug concentrations and treatment durations, and the combination of acitretin and IFN?α appears to have stronger inhibitory effects than acitretin or IFN?αalone.
