Group of 41 cases and 26 cases of angina pectoris in CHD were treated with allicin tablet and Xiaoxintong respectively for comparison of their effect and changes in the indices of GMP-140, TXB2, 6-K-PGF1?, NO and hemorrheology were also observed. Results showed that the total effective rate of allicin tablet was 85. 4%, similar to Xiaoxintong. Allicin tablet can markedly lower the level of plasmal GMP - 140, TXB2. but increased the level of NO and substantially improve blood rheology, demonstrating that allicin tablet yield satisfactory effect on angina pectoris in CHD. The possible mechanism might lie on the activation of inhibition of platelets, prevention of thrombosis, dilatation of coronary arteries and peripheral vessels, improvement of hemorrheology.

Objective To investigate whether lipids and reagents would interfere the results when serum total bile acid(TBA) was measured by enzymatic cycling assay.Methods The serum TBA was measured by enzymatic cycling assay.The carry-over contaminations of high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),cholesterol(TC),and triglyceride(TG)rea-gents were evaluated.In order to reduce the interference and carry-over contaminations,different washing procedures and detection sequence were set.Results By measuring the levels of TBA in pooled serums with low and high levels of lipids,the results showed that there was statistically significant difference between the groups with and without the addition of cleaning process before and af-ter TBA measurement(P <0.01).Cleaning with water might be more effective on reducing interference than those with acid solu-tion.Moreover,the mean of TBA levels in HDL-C,TC,TG and LDL-C reagents were (476.06 ± 1.88 ),(127.78 ± 1.18 ), (121.05±1.08),and (2.23±0.51)μmol/L,respectively.The stability of TBA level was greatly affected by HDL-C regents,fol-lowing by TC and TG reagents,and was little affected by LDL-C reagent.Setting up proper detection sequence and flushing proce-dures could obviously reduce the interference(P <0.01),but not completely rule out.Conclusion Analysis sequence and flushing procedures of biochemical analyzer as well as exogenous substance from reagents may seriously affect the accuracy of determination results.To ensure the accuracy and reliability of the results,it is necessary not only to set up reasonable irrigation and reaction se-quence,but also to master the instrument operation,to know the principle of test reaction and the components of reagents as well as equipment maintenance.

ObjectiveTo elucidate the clinical characteristics and the outcome of SARS in elderly pat ients. Methods Clinical data of 66 elderly patients(≥60 years) with SARS were analysed and compared with that of 238 younger adult SARS patients(18-59 years) in the sa me period. Results Sixty-six out of 304 patients(21 7%) with SARS were more than 60 years. Th e mortality rate of SARS in elderly patients was 22 7%. Underlying disease,lon ger course of disease,dyspneic respiration,severe type of SARS,and higher mor tality were more prevalent in elderly patients than those in the younger adult S ARS patients(P

Objective To investigate the association of common polymorphism loci of the cystic fibrosis transmembrane conductance regulator (CFTR) gene with the onset of primary intrahepatic lithiasis (PIL) in the Chinese Han population. Methods A total of 104 patients with PIL who attended The 900th Hospital of PLA Joint Logistics Support Force from June to November 2018 were enrolled as PIL group, and 120 healthy controls who underwent physical examination during the same period of time were enrolled as control group. Sanger sequencing was used to detect the alleles and genotypes at the M470V, TG-repeats, and Poly-T loci of the CFTR gene. The two groups were compared in terms of age, sex ratio, age of onset, and allele and genotype frequencies, and the association of the above three polymorphism loci of the CFTR gene with the risk of PIL was analyzed. The K-S test was used to determine the normality of continuous variables. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the chi-square test was used to compare categorical data and allele/genotype frequencies and analyze Hardy-Weinberg equilibrium. A binary logistic regression analysis was used to investigate the association of genotypes and alleles with the risk of the disease. The association of the loci deviating from Hardy-Weinberg equilibrium with the risk of PIL was expressed as adjusted odds ratio ( OR ). Results There were significant differences between the PIL group and the control group in the distribution of alleles ( χ 2 =15.139, P < 0.01) and genotypes ( χ 2 =22.889, P < 0.01) at the M470V locus, while there were no significant differences between the two groups in the distribution of alleles and genotypes at the TG-repeats and Poly-T loci (all P > 0.05). The PIL group had a significantly higher frequency of G allele at the M470V locus than the control group (60.1% vs 41.67%, P < 0.01). Compared with the individuals with AA genotype, the individuals with GG and AG genotypes had a significant increase in the risk of PIL ( OR =4.680 and 2.500, both P < 0.01). As for the TG-repeats locus, the individuals with 12TG/13TG genotype had a significantly higher risk of PIL than those with 11TG/12TG genotype ( OR =11.002, P =0.042), and as for the Poly-T locus, the individuals with 7T/5T genotype had a significantly lower risk of PIL than those with 7T/7T genotype ( OR =0.079, P =0.047). Conclusion The M470V polymorphism of the CFTR gene is independently associated with the risk of PIL in the Chinese Han population, and G allele is a high-risk mutation for the onset of PIL.
