ABSTRACT
This study aims to perform a survey of genetic variation in neuraminidase (NA) gene of influenza A/H3N2 virus, as well as related resistance to NA inhibitors, in Qinghai Province of China, 2010 to 2012. Strains of influenza A/H3N2 isolated during an influenza survey from 2010 to 2012 in Qinghai were enrolled by random sampling. Viral RNA was extracted and amplified by RT-PCR. Purified PCR products were sequenced thereafter. Genetic analysis of nucleic acid and the derived amino acid sequences was performed by MEGA 4.0. Phylogenetic trees were also constructed. Strains isolated during 2010-2011 in this study clustered closely with World Health Organization (WHO) 2010-2012 reference vaccine strain A/Perth/16/2009 and 2008-2010 reference vaccine strain A/Brisbane/10/2007 on the phylogenetic tree, while the 2012 isolates were located on another branch. In analysis of derived amino acid sequences, the 2010 isolates mutated at K81T, the 2011 isolates mutated at I26V and D127N, while the 2012 isolates mutated at E41K, P46A, I58V, T71N, L81P, D93G, D127N, D151N, and I307M. The D151N mutation added a glycosylation site to the activity center of NA. No significant variation was discovered in H3N2 NA gene of 2010-2011 isolates in Qinghai, China. Isolates of 2012 were found with significant mutation, which has the potential of inducing minor resistance to NA inhibitors like zanamivir and oseltamivir.

<p><b>OBJECTIVE</b>To investigate the effects of occupational exposure to formaldehyde on the micronuclei frequencies in peripheral blood lymphocytes of workers.</p><p><b>METHODS</b>Two hundred thirty six plywood workers were divided into 3 exposure groups (low, middle and high) according to internal exposure biomarker (formaldehyde human serum albumin conjugate, FA-HSA), which was detected by ELISA. The concentrations of formaldehyde (FA) in air of two workshops were measure using the high performance liquid chromatography. Cytokinesis-block micronucleus (CBMN) test was used to detect the micronuclei frequencies of peripheral blood lymphocyte in 236 workers.</p><p><b>RESULTS</b>The average concentrations of FA in the low and high exposure workshops were 0.58 +/- 0.20 and 1.48 +/- 0.61 mg/m3, respectively, there was significant difference (P < 0.01). The average concentrations of serum FA-HAS of workers in two workshops were 69.22 +/- 15.37 and 136.29 +/- 89.49 pg/ml, respectively, there was significant difference (P < 0.01). The results of CBMN test showed that the micronucleus frequencies in low, middle and high exposure groups were 1.94 +/- 1.72, 2.10 +/- 1.92 and 2.10 +/- 1.70 per thousand, respectively, there were no significant differences between groups. However, the micronucleus frequencies in accumulative low, middle and high exposure groups were 1.36 +/- 1.36, 2.31 +/- 1.81 and 2.49 +/- 1.92 per thousand, respectively, there were significant differences between different accumulative exposure groups (P < 0.01). The results of correlation analysis indicated that there was a positive correlation between accumulative exposure levels and micronucleus frequencies (r(s) = 0.321, P < 0.01). The accumulative exposure doses may be a risk factor for high micronucleus frequencies in workers exposed to FA (P(trend) = 0.002).</p><p><b>CONCLUSION</b>FA-HSA levels can serve as an internal exposure biomarker for assessing the exposure level of workers exposed to FA. Accumulative formaldehyde exposure resulted in an increase of micronuclei frequencies of peripheral blood lymphocyte in plywood workers.</p>

The study was aimed to explore the NF-kappaB continual activity and the expression of WT1 and MDR1 in acute non-lymphocytic leukemia (ANLL) patients, and to investigate if the three factors affect the curative effect of ANLL together as to provide some theoretical basis for finding new measures to improve the curative effect of refractory ANLL. The bone marrow samples of 45 ANLL patients was collected. 45 patients including 20 primary ANLL patients (A group) and 25 refractory ANLL patients. Refractory ANLL patients were divided into 2 sub-groups (B, C groups). The primary patients who was no effect after more than two courses of treatment were taken as group B, and the patients with more than two relapses were taken as group C. At the same time, 15 patients with simple iron deficiency anemia were collected as negative control. The NF-kappaB continual activity was measured by using electrophoretic mobility shift assay (EMSA) and the expressions of WT1, MDR1 were detected by reverse transcriptase polymerase chain reaction (RT-PCR). The results showed that the activity of NF-kappaB and the expressions of WT1, MDR1 were not detected in 15 samples of simply iron deficiency anemia subjects. The NF-kappaB continual activity, the expression levels of WT1 and MDR1 in the refractory group were significantly higher than that in primary group (P<0.001). But the NF-kappaB continual activity, the expression of WT1 gene and MDR1 gene were not significantly different between group B and group C (P>0.05). By assaying the relativity between the them the NF-kappaB continual activity and the expression of WT1 or MDR1 had positive correlation in ANLL patients. It is concluded that the NF-kappaB continual activity, the overexpression of WT1 and MDR1 may be one of the reasons causing poor curative effect in acute non-lymphocytic leukemia. The NF-kappaB continual activity and the expression of WT1, MDR1, all show positive correlation in ANLL patients.

Renin-angiotensin system (RAS) has been shown to be involved in the growth, production, proliferation and differentiation of the bone marrow (BM) hematopoietic cells, while aplastic anemia (AA) is a disease in which proliferation ability of the BM hematopoietic cells is damaged with defective hematopoietic microenvironment. To investigated the pathogenesis of AA, the rennin activity, angiotensin I (Ang I) and angiotensin II (Ang II) concentration in peripheral blood and BM of 22 AA patients were detected by radioimmunoassay, 16 nonhematological disease patients with normal blood counts and BM picture were used as control, and the difference between two groups was compared. The results showed that BM Ang II concentration in the AA patients was significantly lower than that in the control (P < 0.01). In nonhematological disease patients, Ang II concentration in BM was significantly higher than that in peripheral blood, the renin activities and Ang I concentrations were not significantly different in the two groups (P > 0.05). In conclusion, the decreased BM Ang II concentration in AA patients may be involved to the pathogenesis of AA.

To investigate the chemosensitizing effect of pyrroledithiocarbomate (PDTC) on daunorubicin in drug-resistant leukemic cells in vitro, MTT method was used to observe the changes of the proliferation of intractable leukemia MNC treated with daunorubicin (30 microg/ml) combined with PDTC (25, 50 or 100 micromol/L). The results showed that inhibiting rate of daunorubicin combined with PDTC(25, 50 or 100 micromol/L) on drug-resistant leukemic cells was significantly higher than that of daunorubicin alone (P < 0.05). Among the three different doses of PDTC, the concentration of 50 micromol/L of PDTC inhibited the proliferation of drug-resistant leukemic cells significantly. In conclusion, PDTC can sensitize anti-tumor effect of daunorubicin in vitro. The concentration of 50 micromol/L of PDTC has stronger chemosensitizing effect on daunorubicin than that of the other concentrations of PDTC (25 micromol/L or 100 micromol/L) in vitro.
