The pathogenicity of a field isolate of Marek's disease virus (MDV) named GXY2 integrated with retroviral long terminal repeat (LTR) sequence from a chicken with MD tumors was evaluated. Experimental chickens were divided into group A, B, C, D and E. The later four groups were vaccinated on one-day-old with CVI988/Rispens for group B and D, with HVT for group C and E, while group A was taken as no-vaccinated control. On 8-day-old, group A, B and C were challenged with GXY2 by intra-abdominal injection, group D and E were kept as un-challenged control. All the birds were raised routinely until 82 days post-challenge (PC), died birds during the experiment and the slaughtered birds at the end of the experiment were necropsied and examined for gross lesions of MD and further confirmed by a developed polymerase chain reaction (PCR) based differential diagnosis technique for avian neoplastic diseases. The results showed that time of onset of MD death of group A, B and C were PC 25, 77 and 29 days with the incidences of visible MD visceral tumors. On PC 82 days, tumor incidences and mortalities of group A, B and C were 72%, 34.8% and 50%, 84%, 21.7% and 20%, respectively. The vaccination protection of CVI988/Rispense and HVT were 51.67% and 30.56% respectively. Among all the visceral organs, heart had the highest tumor incidences (23.5%), and then followed by liver (14.7%) and gizzard (10.3%). The weight-gain of unvaccinated birds was significantly depressed and severe dystrophy of thymus and bursa of Fabricius were also found. The results of the study demonstrated that isolate GXY2 possessed the ability of causing acute tumors and overcoming the protection of the vaccinations of either CVI988/Rispense or HVT.

OBJECTIVETo analyze the toxicity of high-frequency electromagnetic field (HF-EMF) on the reproductive and endocrine functions of female workers.

METHODS180 female workers exposed to HF-EMF for more than one year were selected as the exposure group, and 349 female workers in the marketplace were selected as the control group. Their menstrual status and pregnancy outcomes were evaluated with historical cohort study. Meanwhile, the serum levels of reproductive hormones including follicle stimulation hormone (FSH), luteinizing hormone (LH), estradiol (E(2)) and progesterone (P(4)) from 30 workers respectively in the exposure group and the control group selected randomly (in periovulatory period) were detected with the radio immunoassays.

RESULTSWith the increase of residue of HF-EMF, the incidence of menstrual disorder was increased (33.8% and 26.8% in the exposure group compared with 12.0% in the control group) (P < 0.01) and the incidence of menorrhagia in the exposure I group (16.9%) was significantly higher than that in the control group (8.0%) (P < 0.01). However, serum P(4) was significantly lower in the exposure group [(2.10 +/- 1.57) and (2.39 +/- 1.35) mg/L] than in the control group [(3.80 +/- 2.67) mg/L] (P < 0.01). There was no significant difference in serum E(2), LH and FSH between the exposure and the control groups.

CONCLUSIONIncrease of the incidence of menstrual disorder as well as that of menorrhagia, and decrease of levels of some reproductive hormones are closely associated with HF-EMF (25 approximately 30 MHz).

In order to enhance the anticoagulant properties of decellularized biological materials as scaffolds for tissue engineering research via heparinized process, the decellularized porcine liver scaffolds were respectively immobilized with heparin through layer-by-layer self-assembly technique (LBL), multi-point attachment (MPA) or end-point attachment (EPA). The effects of heparinization and anticoagulant ability were tested. The results showed that the three different scaffolds had different contents of heparin. All the three kinds of heparinized scaffolds gained better performance of anticoagulant than that of the control scaffold. The thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (APTT) of EPA scaffold group were longest in all the groups, and all the three times exceeded the measurement limit of the instrument. In addition, EPA scaffolds group showed the shortest prepared time, the slowest speed for heparin release and the longest recalcification time among all the groups. The decellularized biological materials for tissue engineering acquire the best effect of anticoagulant ability in vitro via EPA heparinized technique.

Recent work indicates that an Aurora kinase inhibitor MK-0457 (VX-680), a small-molecule inhibitor of Aurora kinases A, B, C and BCR-ABL, FLT-3, JAK-2, can block the progression of cell growth cycle, causing apoptosis in a range of human tumors. MK-0457 has the activity against expressions of wild-type and mutated bcr-abl gene, including the T315I mutant, and can inhibit the activity of FLT-3, JAK-2 and their mutated types as well. Clinical applications suggest that the MK-0457 has therapeutic effect on the highly refractory CML and CML with poor prognosis, Ph(+) ALL with T315I mutant, relapse refractory AML and JAK-2 positive myeloproliferative diseases (MPD). The intensive preclinical studies and the on-going phase II clinical trials will open up a new vista of therapy for some hematological malignancies. This review focuses on the pharmacologic action of MK-0457 and its clinical trial as well as combined application.

OBJECTIVETo compare the concentrations of IgA, lactate dehydrogenase, lysozyme and alkaline phosphatase (ALP) in unstimulated (UWS) and stimulated (SWS) whole saliva between children with severe early childhood caries (S-ECC) and children without caries.

METHODSOne hundred and ninety-two children aged from 42 to 54 months were recruited from 11 urban kindergartens in Beijing. The S-ECC group contained 98 children with more than 5 decayed teeth, and the control group contained 94 caries-free children. The age and sex were matched in the two groups. Two milliliter UWS and 2 ml SWS was collected between 9 and 11 a.m. The salivary IgA was measured by immunoturbidimetric technique. The concentrations of lactate dehydrogenase and ALP were measured by continuous monitoring method, while lysozyme was detected by turbidimetric technique. All results for paired observations between unstimulated and stimulated whole saliva were analysed by paired-samples t test.

RESULTSIn both UWS and SWS, the concentrations of IgA, lactate dehydrogenase and lysozyme in S-ECC children were higher than those in caries-free children (P < 0.01), but the concentration of ALP showed no significant difference in SWS between S-ECC children and caries-free children (P > 0.05).

CONCLUSIONSThe presence of early childhood caries may be associated with an increase of IgA, lactate dehydrogenase and lysozyme in unstimulated and stimulated whole saliva.
