Objective To understand the incidence and trend of malaria in Xuzhou City so as to provide the evidence for formulating the malaria control measures. Methods The information of network reported malaria cases and epidemiological da-ta were collected and analyzed statistically in Xuzhou City from 2010-2013. Results A total of 109 malaria cases were reported by the special report systems and the network report system in Xuzhou City from 2010 to 2013 in which there were 44 cases 40.37% of vivax malaria 62 cases 56.88% of falciparum malaria 2 cases 1.83% of quartan malaria 1 case 0.92% of ovale malaria. The latter three were all imported from other countries. Totally 93 cases 85.32% were confirmed by laboratory and other 16 cases 14.68% were diagnosed clinically. There was the incidence throughout the year and there were no obvious seasonal characteristics. The positive rate of blood test in the floating population was significantly higher than that of the local res-idents χ2 868.23 P<0.01 . Conclusion The malaria endemic situation is in the steady decline period in Xuzhou City. The local infections decrease significantly but the imported falciparum malaria cases increase year by year. Therefore the manage-ment for floating population and fever patients should be strengthened.

Objective To elucidate the influences of epitope competition on the frequency and average intensity of specific T cell response.Methods C57BL/6 mice were immunized with either single epitope DNA vaccines (pSV-gag92 or pSV-env203) or fusion gene DNA vaccine (pSV-gag/env).Gag92and Env203 epitope-specific CD8 T cell responses were analyzed by intracellular cytokine staining assay.Results Gag92-specific IFN-γ+CD8 T cells that were induced by pSV-gag92 accounted for 0.415 00% ±0.045 88% of the total CD8 T cells,which was much more than that induced by pSV-gag/env of 0.058 67% + 0.019 64%.Moreover,the mean fluorescence intensity of Gag92-specific TNF-α-IFN-γ+CD8 T cells (296.70+14.08) elicited by pSV-gag/env was significantly lower than that of Env203-specific TNF-α-IFN-γ+CD8 T cells (818.00+49.34).Conclusion Epitope competition could significantly decrease both the frequency and the average intensity of specific T cell response to subdominant epitopes.

Objective To investigate whether apolipoprotein E (ApoE) genotypes is associated with postoperative delirium in aged noncardiac surgical patients. Methods Two hundreds and twelve inpatients over 65y, undergoing selective noncardiac surgeries were enrolled in the study. The patients were frequently interviewed and evaluated prospectively for delirium with the Confusion Assessment Method (CAM) during the first three postoperative days. APOE genotype was determined using multiplex amplification refractory mutation system pelymerase chain reaction (multi-ARMS PCR) technique. Results Delirium occurred in 45 patients during the first three postoperative days. Of the 212 patients, 18 (8.5%) possessed one or two ApoE 84 allele. There was no significant difference between delirious patients and non-delirious patients(6.7% : 9.0%, P >0.05) in the presence of ApoE ε4 allele. In all four ApoE ε4/4 homozygote patients, one female patient presented a transient delirium status three days be-fore surgery, another male patient presented serious fluctuated delirium symptoms from the second to 17th days after operation. Conclusion The presence of ApoE ε4 allele seems not a predictator of postoperative delirium. ApoE ε4/4 homozygote patients may be more indulgent to delirium than others.

The correlation of single nucleotide polymorphism (SNP) rs10569304 on the second expressed region of hole gene and congenital heart disease (CHD) of human being, and the effect of hole gene on CHD were investigated. 179 patients with CHD as CHD group and 183 healthy people as control group were selected in the case-control study. DNA was abstracted from the peripheral blood by phenol-chloroform method. Primer was designed for the flanking sequence of SNP rs10569304 on the second expressed region of hole gene. The genotype was identified by PCR degenerative acrylamide electrophoresis with amplification products. Then the three amplification products received sequencing. By chi-square test, the genotype frequency and allele frequency in CHD group and control group were analyzed. There was insertion-deletion (GCC/-) of SNP rs10569304 which corresponded to alleles of A and B in Southern Chinese people. The genotype frequency and allele frequency in control group and CHD group were met the Hardy-Weinberg equilibrium. By chi-square test, in control group and CHD group, the genotype frequency of AA (insertion homozygous), AB (insertion-deletion heterozygous) and BB (deletion homozygous) was 21.31%, 54.09%, 24.59% and 16.75%, 46.36%, 36.87%, respectively. The distributional difference of genotype frequency had statistical significance (chi (2)=6.51, P<0.05); The allele frequency of A and B was 48.36% and 51.64% in control group, 39.94% and 60.06% in CHD group, respectively. The distributional difference of allele frequency had statistical significance (chi (2)=5.20, P<0.05). Meanwhile, by contrast with the control group, the BB genotype frequency and B allele frequency in CHD group was higher, but the AA and AB frequency was lower. There was higher risk to suffer from CHD involving B allele. BB genotype had 1.907-fold increased risk of developing CHD according to AA genotype (P<0.05). It is concluded that there is insertion-deletion (GCC/-) of SNP rs10569304 in the Southern Chinese people, and the people whose hole gene involving BB genotype have higher risk to suffering from CHD.

The correlation of single nucleotide polymorphism (SNP) rs 10569304 on the second ex-pressed region of hole gene and congenital heart disease (CHD) of human being, and the effect of hole gene on CHD were investigated. 179 patients with CHD as CHD group and 183 healthy people as control group were selected in the case-control study. DNA was abstracted from the peripheral blood by phenol-chloroform method. Primer was designed for the flanking sequence of SNP rs10569304 on the second expressed region of hole gene. The genotype was identified by PCR de-generative acrylamide electrophoresis with amplification products. Then the three amplification products received sequencing. By chi-square test, the genotype frequency and allele frequency in CHD group and control group were analyzed. There was insertion-deletion (GCC/-) of SNP rs10569304 which corresponded to alleles of A and B in Southern Chinese people. The genotype fre-quency and allele frequency in control group and CHD group were met the Hardy-Weinberg equilib-rium. By chi-square test, in control group and CHD group, the genotype frequency of AA (insertion homozygous), AB (insertion-deletion heterozygous) and BB (deletion homozygous) was 21.31%, 54.09%, 24.59% and 16.75%, 46.36%, 36.87%, respectively. The distributional difference of geno-type frequency bad statistical significance (χ2=6.51, P<0.05);The allele frequency of A and B was 48.36% and 51.64% in control group, 39.94% and 60.06% in CHD group, respectively. The distribu-tional difference of allele frequency had statistical significance (χ2=5.20, P<0.05). Meanwhile, by contrast with the control group, the BB genotype frequency and B allele frequency in CHD group was higher, but the AA and AB frequency was lower. There was higher risk to suffer from CHD in-volving B allele. BB genotype had 1.907-fold increased risk of developing CHD according to AA genotype (P<0.05). It is concluded that there is insertion-deletion (GCC/-) of SNP rs10569304 in the Southern Chinese people, and the people whose hole gene involving BB genotype have higher risk to suffering from CHD.
