Objective To study the relationship between the concentration of oxidized low density lipoprotein(Ox-LDL)and ca-rotid intima-media thickness(IMT)in acute cerebral infarction(ACI group).Methods 44 ACI patients(ACI group)and 30 healthy individuals(control group)were enrolled in the study,whose serum concentrations of Ox-LDL were determined by using enzyme-linked immunosorbent assay(ELISA),and carotid IMT of ACI patients were measured by using ultrasound,then the relationship between Ox-LDL and carotid IMT of ACI patients was analysed.Results The serum concentration of Ox-LDL in ACI group was significantly higher than that in control group(P <0.01).In ACI group,the serum concentration of Ox-LDL was positively correla-ted with carotid IMT(r =0.493,P <0.05 ).In ACI group,the serum Ox-LDL concentrations of patients whose IMT≥1.0 were higher than patients whose IMT<1.0 mm(P <0.05).Ox-LDL concentrations of ACI patients were positively correlated with the carotid IMT(r =0.493,P <0.05 ).Conclusion The serum concentration of Ox-LDL increased significantly in ACI patients,and was closely related to carotid atherosclerosis.

Objective To study the relationship of Helicobacter pylori(Hp)infection degree with serum pepsinogen(PG)and the tumor markers related with gastric cancer .Methods Totally 342 cases of health physical check‐up in our hospital from January to June 2015 were selected .13 C‐UBT was performed to evaluate the Hp infection and infection severitys .The level of serum PG was detected by ELSIA and the levels of tumor markers were detected by luminescence immunoassay .Then the results were statistically analyzed with the SPSS statistical software .Results The positive rate of Hp in 342 research subjects was 49 .42% ,and there was no difference between the male and the female groups(P>0 .05) .The level of serum pepsinogen Ⅰ (PGⅠ )and pepsinogen Ⅱ (PGⅡ)in the Hp(+ + )and Hp(+ + + )groups was significantly higher than that in the Hp negative group ,while the PGⅠ /PGⅡ lev‐el was significantly lower than that in the negative group (P<0 .05) .The level of carbohydrate antigen 724(CA724)and carcino‐em‐bryonic antigen(CEA)had the statistical difference between the Hp(+ + + ) group and the Hp negative group(P= 0 .040 ,P=0 .010) .The Pearson correlation analysis displayed that Hp infection was related with PG Ⅰ ,PGⅡ ,PGⅠ /PGⅡ ,CA724 and CEA . There was a positive correlation between PG Ⅱ and CA50)(r=0 .116 ,P=0 .032);there was a negative correlation between PG Ⅰ /PGⅡ and CA50(r= -0 .193 ,P=0 .000) .Conclusion The combined detection of Hp ,PG and tumor markers could be used as one of methods for screening benign and malignant gastric diseases in the healthy physical check‐up population ,which has an important value for the prevention and intervention of related disease occurrence and development .
