Objective To explore the relationship between interleukin-8 (IL-8) gene 1633C/T polymorphism and late-onset Alzheimer's disease in order to provide genetic reference data for late-onset Alzheimer's disease.Methods Polymorphism distribution of IL-8 gene 1633C/T in 80 LOAD and 80 normal controls were detected by polymerase chain reaction-restriction fragment length polymorphism(PCRRFLP) analysis.The alleles and gene frequencies type were calculated by the direct counting.Type of gene was proceeded with the Hardy-Weinberg balance estimate.The other statistical analyses were carried out with SPSS13.0 software.The genotype frequencies and allele frequencies were compared with the Chisquare test (x2 test).Results For IL-8 gene1633 C/T,the genotype frequencies (CC,20.0％ ; CT,41.2％ ; TT,38.8％) in the LOAD group were not significantly different from those (CC,11.3％ ; CT,40.0％ ; TT,48.7％) in the control group (P ＞ 0.05).Conclusions IL-8 gene 1633 C/T polymorphism is probably not related to the genetic susceptibility of late-onset Alzheimer's disease.

Objective To study the relation between IL-8 gene-251A/T polymorphism and delayed Alzheimer's disease (AD)in Xinjiang Han people .Methods Eighty delayed AD patients served as a delayed AD group and 80 subjects undergoing physical examination served as a control group in this study .Distribution of IL-8 gene-251A/T polymorphism in two groups was detected by PCR-RFLP .Results The distribution of genotypes and alleles was different in two groups (P=0 .023 , P= 0 .010) .Further stratified analysis showed that the frequency of A allele was significantly higher in delayed AD group than in control group (OR= 1 .851 ,95% CI:1 .159 -2 .957 ,P=0.010) ,indicating that A allele is the risk factor for delayed AD .The frequency of AA genotype was significantly higher in delayed AD group than in control group (OR=3 .370 ,95% CI:1 .143-9.939 ,P=0 .023) ,indicating that the risk of delayed AD was 3 .370-fold higher in subjects with AA genotype than in those with TT genotype .The AT genotype was not related with the risk of delayed AD (OR=1 .944 ,95% CI:0 .994-3 .803 ,P=0 .051) .Conclusion IL-8 gene-251A/T pol-ymorphism is related with the risk of delayed AD .

Objective To observe the effects of creatine phosphate sodium on heart function and B -type natriuretic peptide in patients combination with ischemic cardiomyopathy and intractable heart failure .Methods 70 cases of coronary heart disease combined with ischemic cardiomyopathy and intractable heart failure were randomly ( with the random number table ) divided into the control group ( n=33) and the creatine phosphate sodium treatment group (n=37).The control group treated with conventional therapy (digitalis,diuretics,vasodilator,ACEI,et al) ten days;the treatment group with creatine phosphate sodium treatment on the basis of conventional therapy .The symp-tom,sign of the heart failure patients of the two groups before and after treatment were observed .NYHA cardiac func-tional grading were estimated.Echocardiography was used to detect left ventricular end -systolic diameter(LVESD), left ventricular end diastolic diameter ( LVEDD ) and left ventricular ejection fraction ( LVEF ); amino terminal pro brain natriuretic peptide (NT-proBNP) tested by laboratory of the two groups.Drug treatment for 10 days,the chan-ges of the indicators before and after treatment were observed .Results After treatment , compared with the control group[(50.63 ±4.67) mm,(61.30 ±4.58) mm].LVESD,LVEDD of the creatine phosphate sodium treatment [(47.16 ±4.30)mm,(57.92 ±4.30)mm]significantly decreased(t=5.73,4.96,all P<0.01),LVEF[(40.57 ± 4.51)%,(37.63 ±4.53)%]increased significantly(t =5.53,P<0.01).After ten days of treatment levels of NT-proBNP decreased in both two groups [(1 659.±248.18) pg/mL,1 899.3 ±205.45] than before treatment [2 043.46 ±217.04,(2 105.46 ±239.09)pg/mL](t=3.23,3.64,all P<0.05),and the decrease degree of the creatine phosphate sodium treatment group was more obvious than those of the control group (t=4.11,P<0.05). Conclusion Creatine phosphate sodium can improve the cardiac function and left ventricular ejection fraction of ischemic cardiomyopathy and intractable heart failurepatients ,enhance the clinical symptoms of patients .

Objective To study the clinical application of the complete audiologic evaluation battery consisting of ABR,ASSR and behavioral audiometry in sound field for the identification of sensorineural losses in children.Methods In the study 48 children were divided as group PTA of the children assessed by pure tone audiometry and ABR and ASSR test,and group BA of the children unable to perform on behavioral evaluations.Results The analysis of the audiometric results of group PTA showed significant correlation between the ASSR thresholds and pure tone thresholds(P＜0.01) at various frequencies.The correlation coefficients were 0.75,0.76,0.76,and 0.83 at different frequencies.The ASSR-PTA linear regression was utilized.The comparison of the ABR and ASSR results of group BA indicated that 23 ears responded in ASSR but without responses in ABR.Those without ASSR responses also had no ABR There were 116 tests in total four frequencies for the 29 ears.83 responses were obtained from ASSR,89 responses from behavior audiometry and 96 from the use of the both tests.Conclusion The comprehensive audiologic evaluation battery could be used to test younger children with severe heating loss children as compared to the pure tone audiometry alone.More detailed data can be obtained thus from children to assist in rehabilitation in a more effective mariner.

A benzyl functionalized ionic liquid, 1-benzyl-3-methylimidazolium bis [( trifluoromethyl ) sulfonyl]imide ([BeMIM][Tf2 N]), was synthesized and characterized as an extraction solvent of dispersive liquid-liquid microextraction ( DLLME) for enrichment and determination of 5 organophosphorus pesticides (phoxim, fenitrothion, chlorpyrifos, phorate and parathion) and 2 aromatic compounds (chloronaphthalene and anthracene) from environmental water samples by high-performance liquid chromatography ( HPLC). [BeMIM] [ Tf2 N] had higher extraction efficiency than 1-octyl-3-methylimidazolium bis [( trifluoromethyl) sulfonyl]imide and common organic solvents such as CCl4 and C2 Cl4 . The extraction was performed using 40 μL of [BeMIM][Tf2N] and 1 mL of methanol as extraction solvent and dispersive solvent respectively with centrifugal time of 5 min. Under the optimal conditions, the method proposed here provided a good linearity for all analytes with correlation coefficients between 0. 9994 and 0. 9998. The repeatability values, described as intra-day and inter-day relative standard deviations (RSDs) of five replicate experiments at three different concentrations of 10, 40 and 100 μg / L, were 1. 1% -4. 3% and 0. 8% -4. 8% , respectively. The limits of detection (LOD) were 0. 01 μg / L-1. 0 μg / L at a signal-to-noise ratio (S / N) of 3. This developed method was convenient and speedy, and could be employed to detect the analytes in three real environmental water samples with satisfactory relative recovery of 82. 7% -118. 3% and RSD of 0. 7% -5. 6% . Introduction of benzyl group into the imidazolium could obviously enhance the extraction efficiecny for analytes due to the π-πinteraction between [BeMIM] [ Tf2 N] and analytes. [ BeMIM] [ Tf2 N] was a satisfactory extraction solvent with a high enrichment factor of 339 and extraction efficiency of 81. 4% . Partition coefficients of all analytes in [BeMIM][Tf2 N]-DLLME system were determined and the extraction mechanism was discussed.

OBJECTIVE:To study pharmacokinetics of domestic and imported Phenazopyridine hydrochloride tables and bioavailability of domestic tablets, and to evaluate the bioequivalence of two kinds of tablets. METHODS: A randomized crossover design was performed in 18 healthy male volunteers. They received a single oral dose of domestic or imported tablets 200 mg. Plasma concentration of phenazopyridine hydrochloride was measured by HPLC. The pharmacokinetic parameters were calculated by 3p97 software and relative bioavailability was evaluated. RESULTS: The plasma concentration-time curves of domestic and imported tablets conformed to one-compartment model. Main pharmacokinetic parameters of domestic tablets vs. imported tablets were as follows: t1/2Ke(3.52?2.03) h vs. (3.18?1.85)h; tmax(0.76?0.33) h vs. (0.79?0.43)h; Cmax(76.41?70.15) ng?mL-1 vs. (75.49?70.37) ng?mL-1; AUC0～8(159.10?116.32) ng?h?mL-1 vs. (164.65?129.89) ng?h?mL-1; AUC0～∞(237.12?115.06) ng?h?mL-1 vs. (262.69?155.05) ng?h?mL-1. The relative bioavailability of domestic tablets was (96.63?14.05)% compared with imported tablet. There was no significant difference between the pharmacokinetic parameters of two formulations by variance analysis, t-test and 1-2? confidence interval method. CONCLUSION: The domestic and imported tablets are bioequivalent.
