Objective To investigate the relationship between essential hypertension and serum C-reactive protein and plasma lipids.Methods Detecting fasting serum CRP and plasma lipid in each group of hypertensive patients to investigate the relationship between hypertension and fasting serum CRP and plasma lipids.Results CRP,TC,TG,HDL-C and LDL-C level of A,B and C group had significant differences with that of D group(t =4.03, 4.23, 4.61, 3.12, 3.41, 2.76,2.98,2.56,2.64,2.57,3.05,3.68,2.54,3.16,4.28,all P＜0.05).CRP,TC,TG,HDL-C and LDL-C levels between A,B and C group had significant differences(F = 4.68,4.05,3.29,3.59,4.11,all P＜0.05).There was significant correlation between serum CRP level and TC,TG,HDL-C,LDL-C level in 186 hypertension patients(r =0.274,0.356,0.327,0.302,all P＜0.05).Conclusion CRP,TC,TG and LDL-C levels showed significant linear correlation in patients with hypertension.

In order to investigate the distribution of Yersinia enterocolitica in Citellus dauricus plague focuses in Inner Mongolia,three different ecological environ/ments were chosen as the sampling area.Feces,tongue roots throat swabs,and intestinal contents of rodent,livestock,and poultry were separately collected,and different Y.enterocolitica strains were isolated,and identified.PCR analysis was conducted to detect the toxicity genes of Y.enterocolitica.Statiscal analysis was performed by chisquare test.Of the 3 260 samples,65 Y.enterocolitica strains were isolated and the overall detection rate was 1.99％.To include O ∶ 3/3,O ∶ 5/1A,O ∶ 4/4 serum biological type,the pathogenic strain of serotype O ∶ 3 and biological typt 3 carryinq toxicity genes ail,ystA,VirF yadA and rfbc was isolated from pigs in Citellus dauricus plague focuses,Inner Mongolia are the major carrier of pathogenic Y.enterocolitica distributed in three different ecological environment,and distributed mainly in agricultural area.
