Objective To compare the difference of the left ventricular structure and diastolic func-tion in normotensive offspring with or without a family history of hypertension. Methods One hundred nor-motensive offspring were assessed. Fifty had a family history of hypertension (experimental group) and 50 had no family hi.history of hypertension (control group). By eehocardiography and Doppler tissue imaging, the following parameters of left ventricular structure and diastolic function were examined: interventricular septal thickness (IVST), left ventrieular posterior wall thickness (LVPWT), left ventricular internal dimension (LVIDed), left ventrieular mass index(LVMI) and E/A. Results Compared with control group, experimen-tal group had higher IVST, LVPWT and LVMI, lower peak velocity of the early diastolic wave (e) of mitral annulus, and lower e/a (P<0.05). No differences in LVIDed, left atrial diameter (LA),aortic dimension(AOD), E,A and E/A were found between the two groups. Conclusion The results indicate that genetic factor of parental hypertension influence left ventrieular structure and diastolic function in normotensive offspring, which may precede the elevation of blood pressure.

Objective To investigate the expression level and clinical significance of WT1 gene in acute luekemia (AL) patients.Methods WT1 gene level was detected by real time quantitative-polymerase chain reaction in acute myelogenous leukemia (AML) and in acute lymphocytic leukemia (ALL) patients.Then the expression levels of WT1 gene in different subtypes of AML were compared,and the correlation between gene expression and disease courses and prognosis were observed.Moreover,the relationship between disease courses and WT1 expression in patiens after receiving haemopoietic stem cell transplantation were analyzed.Results Among 66 cases,WT1 expression positive rate was 87.5 ％ (14/16) in AML and 76.0 ％ (38/50) in ALL.In AML,the expression level in M3 showed the lowest than that in any other subtypes (compared with M1,M2,M4,M5,P value was 0.040,0.007,0.006 and 0.01,respectively).The expression level of WT1 was closely correlated with leukemia disease courses.The expression level in complete remission (CR) group showed a significant lower expression level than that in non-remission group (P =0.018) and relapse group (P =0.003),and the re-increase of WT1 expression level could predict relapse as early as 1.5 months.Moreover,WT1 expression also showed an close relationship with prognosis of patients receiving haemopoietic stem cell transplantation.Patients whose WT1 was undetectable had a better prognosis than those with persistent expression,and increase again after becoming undetectable.Conclusion WT1 has a high expression level in AL,which can represent minimal residual disease.The expression level in M3 was lowest than that in different AML subtypes,and its expression level has a close correlation with clinical disease course and prognosis of AL.

OBJECTIVETo analysis the genotypes of wild type hepatitis A virus circulated in Xinjiang Hetian of China in 2006.

METHODSThe Vp1-2A region of HAV genome was amplified and sequenced from serum samples collected in Xinjiang Hetian of China in 2006, and subjected to phylogenetic analysis by Neighbor Joining (NJ) method.

RESULTSThe nucleotide sequence differences in the VP1-2A region among Xinjiang Hetian HAV strains ranged from 0%-3.9%, all belonged to sub-genotype 1A. Genetically similar strains were identified among Xinjiang Hetian 2006 and Xinjiang Yili 2005 of China isolates. Only 0-2 amino acid differences were found among the Xinjiang Hetian HAV isolates in the VP1-2A region.

CONCLUSIONThere were different HAV strains existing in the investigated areas, these strains may have different transmission pathways for the spread of the disease. The results indicate the usefulness of molecular epidemiological methods in studying changes in the circulating HAV strains and in tracing transmission routes, and also for effectively control measures to prevent the spread of the disease.

Objective To evaluate the protective effect of pterostilbene against ultraviolet B (UVB)-induced acute damage in HaCaT cells,and to explore related mechanisms.Methods The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazo1ium (MTS) assay and flow cytometry were performed to estimate the proliferative activity and the apoptosis and necrosis rate of HaCaT cells treated with different concentrations of pterostilbene respectively,so as to screen the non-toxic concentration of pterostilbene.HaCaT cells were randomly divided into several groups:normal control group receiving no treatment,UVB group irradiated with 57 mJ/cm2 UVB,3 pterostilbene groups treated with 2.44,4.88 and 9.75 μmol/L pterostilbene respectively for 24 hours,3 pterostilbene + UVB groups treated with 2.44,4.88 and 9.75 μmol/L pterostilbene respectively for 24 hours followed by UVB radiation.Western blot analysis was conducted to detect changes of the transcription factor NF-E2-related factor 2 (Nrf2) expression in cell nuclei and cytoplasm before and after the treatment with pterostilbene and UVB,quantitative PCR to determine the mRNA expression of catalase and superoxide dismutase in the HaCaT cells,and enzyme-linked immunosorbent assay (ELISA) to evaluate the activity of catalase and superoxide dismutase.Results MTS assay and flow cytometry showed that 2.44,4.88 and 9.75 μmol/L pterostilbene had non-toxic effect on HaCaT cells.The protein expression of Nrf2 in the nuclei and cytoplasm in the normal control group was 1.03 ± 0.08 and 1.04 ± 0.11 respectively.Compared with the normal control group,the protein expression of Nrf2 in the nuclei and cytoplasm experienced no significant changes in the 2.44-,4.88-and 9.75-μmol/L pterostilbene groups,and the UVB group showed similar protein expression of Nrf2 in the cytoplasm,but significantly increased protein expression of Nrf2 in the nuclei (1.77 ± 0.08,q =17.24,P ＜ 0.01).Compared with the normal control group and UVB group,the 2.44-,4.88-and 9.75-μmol/L pterostilbene + UVB groups all showed significantly lower protein expression of Nrf2 in the cytoplasm (0.86 ± 0.10,0.87 ± 0.11 and 0.46 ± 0.11 respectively,all P ＜ 0.05),but significantly higher protein expression of Nrf2 in the nuclei (2.38 ± 0.11,2.57 ± 0.11 and 2.07 ± 0.13,all P ＜ 0.01).As qPCR showed,UVB radiation could significantly inhibit the mRNA expression of CAT (P ＜ 0.05),but had no obvious effect on the mRNA expression of SOD (P ＞ 0.05).The mRNA expression of CAT and SOD experienced no significant changes in the 2.44-,4.88-and 9.75-μmol/L pterostilbene groups compared with the normal control group (P ＞ 0.05).However,2.44,4.88 and 9.75 μmol/L pterostilbene could significantly reduce the inhibitory effect of UVB radiation on the mRNA expression of CAT (P ＜ 0.05) and up-regulate the mRNA expression of SOD in the pterostilbene + UVB groups (P ＜ 0.05).ELISA revealed that UVB radiation could inhibit the activity of CAT and SOD in the HaCaT cells (both P ＜ 0.001),while 2.44,4.88 and 9.75 μmol/L pterostilbene could reduce the inhibitory effect of UVB radiation on the activity of CAT and SOD (all P ＜ 0.05).However,the activity of CAT and SOD were still lower in the 2.44-,4.88-and 9.75-μmol/L pterostilbene + UVB groups than in the normal control group (P ＜ 0.05).Conclusion Pterostilbene can prevent UVB-induced acute damage in HaCaT cells by activating the Nrf2 pathway and up-regulating the expression of the downstream antioxidant enzymes CAT and SOD.

Objective To assess the association between killer cell immunoglobulin-like receptor (KIR) gene polymorphisms and the risk of hypertension in autoimmune mechanism.Methods We conducted a case-control study including 205 hypertensives and 205 controls matched with sex and age,from a community-based population.KIR genes of all subjects were genotyped by polymerase chain reaction with sequence-specific primers (PCR-SSP).Conditional logistic regression model and generalized multifactor dimensionality reduction (GMDR) method were used to estimate the association among KIR gene polymorphisms and the risk of hypertension.Results The genotypic frequencies of KIRs were not significantly different between the hypertensives and the control groups (P＞0.05).Among all the models of GMDR concerning the association between interactions of KIR genes and essential hypertension,the testing accuracy of the interaction between K/R2DS2 and KIR2DS3 was the highest (55.13％),with cross-validation consistency as 10/10 (P=0.054).Results from the conditional logistic regression showed that individuals with KIR2DS2 +:KIR2DS3-were significantly associated with an increased risk on hypertension (OR=2.555,95％CI:1.203-5.429,P=0.015).However,individuals with KIR2DS2 +:KIR2DS3 + were significantly associated with a reduced risk of hypertension (0R=0.268,95％ CI:0.088-0.815,P=0.020).Individuals with KIR2DS2-KIR2DS3 + did not seem to be associated with the risk of hypertension (0R=1.602,95％ C I:0.785-3.266,P=0.195),when compared to the KIR2DS2-KIR2DS3-group.Interactions between KIR2DS2 and KIR2DS3 were significantly associated with the risk of hypertension,after adjusted for BMI,smoking,drinking and family history of hypertension (OR=0.065,95％CI:0.013-0.317,P=0.001).Conclusion Individuals with KIR2DS2 and no KIR2DS3 were associated with the increased risk of hypertension.KIR2DS2 that coexisted with KIR2DS3 were associated with the reduced risk of hypertension.Antagonism between KIR2DS2 and KIR2DS3 might serve as a protect factor for hypertension.

Mild hypothermia, as a common means of intraoperative nerve protection, has been used in clinical practice. Compared with the traditional methods such as freezing helmet and nasopharyngeal cooling, hypothermic blood perfusion is considered to be a promising treatment for mild hypothermia, but it lacks experimental and theoretical verification of its cooling effect. In this study, the commercial finite element simulation software COMSOL combined the Pennes equation with the cerebrovascular network model to construct a new simplified human brain model, which was further used to simulate the cooling process of cerebral hypothermic blood perfusion. When the hypothermic blood perfusion was 33 ℃, the human brain could enter the mild hypothermic state within 4 minutes. By comparing with helmet cooling, the feasibility and efficiency of the blood perfusion scheme were verified. By comparing with the calculation results based on Pennes equation, the rationality of the model constructed in this study were verified. This model can non-intrusively predict the changes of brain temperature during surgery, and provide a reference for the setting of treatment parameters such as blood temperature, so as to provide personalized realization of safer and more effective mild hypothermia neuro protection.
