OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

A flavivirus, Culex flavivirus, was first isolated from Chinese mosquitoes with high sequences similarities to those of flaviviruses found in America and Japan. In this study, a total of 48 pools of field-collected mosquitoes were sampled from Dandong of Liaoning Province, China during July to September of 2011. Six isolated viruses showing cytopathic effect (CPE) in C6/C36 cells were tested by reverse transcription polymerase chain reaction(RT-PCR)using Flavivirus genus--specific primers and Culex flavivirus-specific primers and the positive PCR-product was sequenced and compared with the sequences of 10 isolates from GenBank. Phylogenetic tree of NS5 and enevelop genes of flavivirus were constructed. The GenBank accession numbers of NS5 gene were JQ409188, JQ409186, JQ409187, JQ409191, JQ409189 and JQ409190. The GenBank accession numbers of envelope gene were JQ065883, JQ065882, JQ065881, JQ065879,JQ065877 and JQ065878.

Objective To observe the levels of alanine aminotransferase(ALT), total bilirubin(TBIL), hyaluronic acid (HA), procollagen type Ⅲ aminoterminal peptide (P Ⅲ NP) and larninin (LN) in the sera of rats infected with Clonorchis sinensis (C. sinensis) after treatment of albendazole combined with milkvetch root. Methods Thirty-two healthy adult Wistar rats were randomly divided into four groups with 8 in each based on body mass: control group, non-treatment group, Albendazole group(ALB group) and albendazole combined with milkvetch root group(ALB+MR group). The rats in non-treatmen, ALB and ALB+MR groups were infected orally with metacercariae of C. sinensis 50 per rat. The rats in control group were mock-infected with saline. The rats in ALB group were treated to each rat with 50 mg/kg alhendazole for 5 days, and ALB+MR groups were given to same treat with albendazole, meanwhile each rat injected with 800 mg/kg milkvetch root intraperitoneally for 30 days. All rats were killed after infestation 14 weeks and their sera samples were collected to detect ALT, TBIL, HA, PⅢNP, LN. Results There were statistically significant differences in the levels of ALT and LN in the sera of rats between groups(F=31.40,11.82, P<0.01). Compared with control[ (47.88±4.88)U/L, (51.20±4.12)μg/L], the levels of ALT and LN in rats in non-treatment group [(85.50±9.65)U/L, (64.20±4.18) μg/L] and ALB group [(65.29± 7.78) U/L, (58.23±2.55) μg/L] were significantly increased (P<0.05). Compared with non-treatment group, the levels of ALT and LN in rats in ALB group and ALB+MR groups[(50.25±9.29)U/L, (53.68±5.63)μg/L] were significantly decreased(P<0.05), and they decreased more obviously in ALB+MR group (P<0.05). There were statistically significant differences in the levels of TBIL, PⅢNP and HA in the sera of rats between groups (χ2=15.309,21.418,19.759, P<0.01). Compared with control[(0.700±0.350)μmol/L, (26.085±4.075)μg/L, (81.935±42.550)μg/L], the levels of TBIL, PⅢNP and HA in rats in non-treatment group(2.400 μmol/L, 46.220 μg/L,310.885 μg/L) and ALT group(1.200 μmol/L,36.540 μg/L, 178.010 μg/L) were significantly increased(P<0.05). Compared with non-treatment group, the level of TBIL in ALT+MR group(0.750 μmol/L), the levels of pⅢNP and HA in ALT and ALT+MR group(30.470,100.240 μg/L) were significantly decreased(P< 0.05). The levels of TBIL, PⅢNP and HA decreased more obviously in ALB+MR group(P<0.05). Conclusions The liver function in rats infected with C. sinensis is abnormal. The liver function and fibrosis are improved after treatment with albendazole or albendazole combined with milkvetch root. The treatment of albendazole combined with milkvetch root is more effective.

OBJECTIVETo evaluate the role of RNA interference (RNAi) in silencing the enhanced green fluorescent protein (eGFP) expression in 293T and Mel cells.

METHODSNested-PCR was used to amplify H1 promoter from human 293T cells for driving RNAi synthesis. RNAi vectors (TR1) for silencing the eGFP expression was constructed. The eGFP vector and RNAi vector (TR1) were then co-transfected into the 293T and Mel cells, in which the silencing effect on eGFP expression was investigated by fluorescence microscopy, reverse transcription-PCR(RT-PCR), fluorescence-assited cell sorting(FACS) analysis and real-time RT-PCR.

RESULTSRNAi could effectively reduce more than 50 percent of eGFP expression in 293T cells as well as in Mel cells.

CONCLUSIONThe RNAi vector constructed in this way paper can effectively inhibit eGFP expression in cells.

BACKGROUNDParkinson's disease (PD) is an autosomally inherited neurodegenerative disease in elderly people. The etiology of PD has long been thought to be associated with both genetic and environmental factors. To explore potential genetic risk factors for PD in the northern Han Chinese population, we investigated three single nucleotide polymorphisms (SNPs) (rs4538475, rs11107 and rs12564040) in the BST1, PARK15 and PARK9 genes.

METHODSGenomic DNA from 215 PD patients and 212 matched controls was amplified in two independent PCR systems and subsequently genotyped by digestion with the endonuclease PstI. Genetic parameter and association studies were carried out with SPSS 13.0 and PLINK 1.07 software.

RESULTSWe could accurately detect all genotypes in the three loci with the PCR-RFLP or mismatched PCR-RFLP techniques. The observed heterozygosities of the rs4538475 and rs11107 loci in PD and control groups ranged from 0.460 - 0.481 and 0.410 - 0.441, in BST1, PARK15 respectively, while we detected no heterozygosity at the rs12564040 locus in PARK9. The similar distributions of genotypic frequency between both groups suggest that the three SNPs investigated in this study are unlikely to play roles as common risk factors or pathogenic mutations for PD in northern Han Chinese.

CONCLUSIONThe SNPs investigated in the BST1, PARK15 and PARK9 genes associated with PD susceptibility are not associated with PD in the northern Han Chinese population.

OBJECTIVETo investigate the effect of ERCC1 gene on the repair capability of damaged DNA in lung cancer A549 cells induced by benzo[a]pyrene.

METHODSRecombinant plasmid expressing ERCC1 antisense RNA was constructed and transfected into A549 cells by Lipofectin reagent. The stable-transfected cell colonies were selected by hygromycin. Cell viability was determined by the MTT assay. The level of ERCC1 mRNA was measured by Northern Blot analysis. Single cell gel electrophoresis assay was applied to determine the cellular DNA damage and fifty cells for each group were counted.

RESULTSSeven positive colonies expressing ERCC1 antisense RNA were screened. There was no growth rate difference between the antisense-transfected cells and the parental cells. The endogenous mRNA level in transfected colonies decreased in varied degrees, i.e. 12% approximately 86% of that of the parental cells in Northern Blot assay. After 24 h treatment of 10 micro mol/l benzo[a]pyrene, the repair capability for DNA damage in transfected colonies was reduced to 29% approximately 71% of that of the parental cells. Also, a statistically significant correlation was observed between expression of ERCC1 mRNA and repair capability (r = 0.84).

CONCLUSIONAntisense ERCC1 RNA decreased the repair capability for damaged DNA in lung cancer cells induced by benzo[a]pyrene.

OBJECTIVETo investigate the effects of autologous bone mesenchymal stem cells (MSC) transplantation on malignant arrhythmia induced by electrophysiological (EP) stimulation and cardiomyocyte ion channels remodeling in a mini-swine model of acute myocardial infarction (AMI).

METHODSImmediately after AMI (LAD occluded for 120 min), MSC (10 x 10(7), labeled by colloidal gold and co-cultivated with 5-azacytidine, 5-aza, n = 12) or equal volume saline (n = 10) were injected through over-the-wire (OTW) balloon in LAD at distal over D(1). EP stimulation is performed after 2 hours and 4 weeks in both groups to induce arrhythmia. The variance of heterogeneity of sodium currents (I(Na)) and I(Na) steady-state inactivation curves in different zones of infracted wall were investigated by patch clamp technology and the relationship between ionic channel and ventricular arrhythmia is analyzed.

RESULTSEP induced malignant ventricular arrhythmia (VT) rate was similar (MSC 75% vs. saline 90%, P = 0.455) at 2 hours post AMI and was significantly lower in MSC group (25% vs. 80%, P = 0.012) at 4 weeks post AMI. The Peak I(Na) current densities of the Endo, Media and Epi were significantly lower in MSC group [(-14.04 +/- 3.82) pA/pF, (-29.26 +/- 5.70) pA/pF, (-12.43 +/- 3.04) pA/pF] compared those in saline group [(-9.71 +/- 3.38) pA/pF, (-18.98 +/- 4.05) pA/pF, (-8.47 +/- 3.34) pA/pF, all P < 0.05]. The I(Na) steady-state inactivation curves of the Epi, Endo and Media in mini-swine with VT in MSC group [(-126.2 +/- 10.9) mV, (-106.7 +/- 11.9) mV, (-105.4 +/- 11.0) mV] were similar as those in saline group with VT [(-129.1 +/- 10.9) mV, (-112.2 +/- 9.9) mV, (-109.7 +/- 9.2) mV, all P > 0.05] while significantly lower compared to MSC group without VT [(-93.1 +/- 13.8) mV, (-95.2 +/- 15.5) mV, (-103.4 +/- 8.7) mV, all P < 0.05]. The multiple logistic regression analysis showed that I(Na) current density (RR = 1.449, 95% CI 1.276 - 2.079, P = 0.029) and I(Na) steady-state inactivation curves (RR = 1.092, 95% CI 1.008 - 1.917, P = 0.012) were the independent factors for reduced VT.

CONCLUSIONSAutologous MSC attenuated malignant ventricular arrhythmia induced by EP at 4 weeks in mini-swine with AMI which might due to altered cardiomyocyte ion channels remodeling induced by MSC.
