OBJECTIVETo investigate the differences in the onset age and pathology of prostate cancer between Uygurs and Hans in Xinjiang.

METHODSWe enrolled in this study 518 patients (138 Uygurs and 380 Hans) with prostate cancer confirmed between January 2002 and December 2011. We conducted comparative analyses on their ages, years of diagnosis and Gleason scores.

RESULTSThe incidence of prostate cancer increased year by year in both Uygur and Han people, but no statistically significant differences were found in the years of diagnosis between the two groups (chi2 = 1.063, P = 0.900). The median and mode ages of the Uygur patients were 70 and 63 years, and those of the Hans 73 and 71 years. The predilection age of prostate cancer was 70 -79 years in both the two groups. The Uygurs showed a significantly higher incidence of prostate cancer in the 50-59 yr and 60-69 yr groups than the Hans, but the results were just the opposite in the 80-89 yr group (chi2 = 40.375, P = 0.01). The median and mode of Gleason scores were 7 and 6 in the Uygurs, and 8 and 8 in the Hans, respectively, with no significant difference between the two groups (chi2 = 0.991, P = 0.01).

CONCLUSIONThe Uygurs differed from the Hans in the age of prostate cancer onset, but there were no significant differences in the annually increased incidence and pathological stage of prostate cancer between the Uygurs and Hans in Xinjiang.

OBJECTIVETo quantify human cytomegalovirus (HCMV) DNA in the blood and urine of infants of different ages with suspected HCMV infection, and in the breast milk of their mothers, and to evaluate the significance of HCMV DNA detection in the three specimen types in the diagnosis of HCMV infection among infants of different ages.

METHODSA total of 170 infants with suspected HCMV infection were divided into groups A (<28 days; n=43) and B (28 days to 5 months; n=127) according to their ages. Blood and urine were collected from the infants, and breast milk was collected from their mothers. The specimens were examined by fluorescence quantitative PCR for detection of HCMV DNA.

RESULTSIn group A, HCMV DNA detection rates in blood, urine and breast milk were 65.1%, 18.6% and 93.0% respectively. In group B, HCMV DNA detection rates in blood, urine and breast milk were 64.6%, 92.9% and 72.4% respectively. HCMV DNA detection rate in urine in group B was significantly higher than in group A (P<0.01), however, HCMV DNA detection rate in mothers' breast milk in group B was significantly lower than in group A (P<0.01). Among the 82 infants with positive results for blood and urine, the copy number of HCMV DNA in urine was significantly higher than that in blood.

CONCLUSIONSHCMV DNA detection rates in urine and breast milk are different among infants of different ages, so use of suitable specimens according to age is of great significance for improving detection rate.

Twenty Newcastle disease virus (NDV) strains were isolated from chickens and geese in the field outbreaks during 2005 and 2006 in some regions of Jiangsu and Guangxi province. Assessment of the virulence by MDT and ICPI, RT-PCR and sequence analysis of fusion protein gene were used to compare the properties of NDV isolates. The results indicated that MDT and ICPI of the isolates were 45.3h - 58.2h and 1.61 - 2.00 respectively, which confirmed that the all NDV isolates were highly virulent. And their hemagglutinin were not resistant to heat and belonged to fast pattern of elution. The results of nucleotide sequencing and phylogentic analysis of fusion protein gene showed that the twenty strains shared homology from 79.7% to 100% among themselves, from 78.1% to 83.4% and from 80.2% to 90.1% with NDV LaSota, F48E8, respectively. The putative amino acid sequences of fusion protein at the cleavage sites of all the isolates were 112R-R-Q-R/K-R-F117, with the motif characteristics of the virulent NDV strain, which was in accordant with the results of assessment of the pathogenicity. The phylogentic tree based on sequences of fusion protein gene variable regions (47-420nt) revealed that the 18 strains belonged to sub-genotype VIId and the others belonged to an old genotype III of NDV, revealing that subgenotype VIId virus was responsible for the NDV outbreaks in some regions of Jiangsu and Guangxi promince recently.

Aim To assess the effects of Trillium Tschonoskii Maxim ( TTM ) decoction on Tau protein phosphorylation and synaptic development in AD model rats induced by high activity GSK-3β. Methods The SD rats were divided into five groups of ten animals, named sham-operated group ( blank group) , AD model group, TTM group (0. 5, 0. 25, 0. 125 g·kg-1 · d-1 ) . Treatment group received gavage once a day for seven days with TTM decoction, while other groups by gavage once a day for seven days with drinking water. On 2nd day by gavage, Morris water maze test was used to assess the spatial learning and memory ability of the rats. After five days' training, rats in the treat-ment groups and AD model group were injected wort-mannin ( WT, PI3K specific inhibitor ) and GF-109203X (GFX, PKC specific inhibitor) (100 μmol ·L-1 of each, total volume of 10 μL) into the right lateral ventricle. Western blot was used to detect the levels of phosphorylation Tau protein at multiple sites and the expression level of PI3K, Akt, PKC, GSK-3β(S9, T216) and synapse-associated proteins. Immu-nohistochemical method was used to detect the hyper-phosphorylation of Tau protein in hippocampus of rats. Golgi staining was applied to detect the number and morphological changes of synaptic development and dendritic spines. Nissl' s staining was employed to ob-serve the development of neonatal neurons in hippo-campus and cortex. Results Western blot showed that the phosphorylation level of Tau in hippocampus increased in model group, and the activity of GSK-3βwas up-regulated. Among them, however, in middle dose TTM group, the phosphorylation level of Tau in hippocampus decreased and the activity of GSK-3βde-creased. The expression levels of p-PKC and p-Akt in low and middle dose treatment group were higher than those in model group, thus increasing the activity of PKC and Akt to inhibit the activity of GSK-3β kinase. Immunohistochemistry also indicated that TTM could decrease the biological effects of Tau phosphorylation in hippocampus of AD rats. Western blot showed that TTM could increase the expression levels of synapsin-1 , syn-aptophysin and GluR-1 in hippocampus of AD rats. Nissl staining showed that the number of Nissl bodies in hippocampal neurons of AD model group were signif-icantly fewer than those of sham operation group, which could be increased by TTM middle and high dose group, and the complexity and dendritic spine density of hippocampal neurons in AD rats could be en-hanced as well. Conclusion TTM can effectively im-prove the cognitive function of AD rats induced by the increase of GSK-3β activity, and its possible mecha-nism may be via down-regulating the activity of GSK-3β and inhibiting the phosphorylation of tau protein and promoting the development of neurons.

Aim To investigate the effects of Evodiamine (EVO) on proliferation and apoptosis of human leukemia cell line K562 and its potential mechanisms. Methods K562 cells were treated with EVO at different concentrations (0, 1, 2, 4, 8, 16, 32, 64 jxmol • L

Objective To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165C in children with enterovirus 71 (EV71) infection in hand foot and mouth disease (HFMD). Methods The polymerase chain reaction (PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay (ELISA). Results The plasma norepinephrine level of severe group was significantly higher than the mild group in children with EV71 infection in HFMD (P < 0.05); however, the levels of plasma adrenaline in two groups had no statistical differences (P > 0.05); There was no significant difference in the distribution of β1 adrenergic receptor G1165C genotype and allele between EV71 infection group and healthy control group (P > 0.05). Further analysis of EV71 infection group by dividing it into mild and severe groups showed that there was no significant difference in the distribution of genotype and allele between these two groups as well (P > 0.05). There was no significant difference in the levels of epinephrine and norepinephrine in different genotypes of EV71 infection group (P > 0.05), and in the levels of plasma epinephrine and norepinephrine in the mild and severe groups (P > 0.05). Conclusions As the disease gets worse, the plasma norepinephrine level has a rising trend in children with EV71 infection in HFMD, which is an important indicator to evaluate the progress of the disease. However, the gene polymorphism of β1 adrenergic receptor G1165C have no significant correlation, not only with the susceptibility and severity of EV71 infection in hand, foot and mouth disease, but also with the levels of catecholamine.
