Objective To assess the relationship between fractional esterification rate of high density lipoprotein cholesterol (FERHDL) and coronary artery disease .Methods The patients were underwent coronary angiography in this hospital in the last three years were collected ,according to the results of coronary angiography ,286 patients were divided into CHD group(n=196) and non-CHD group(control group ,n=90) .And according to the number of pathological coronary artery ,the patients with coronary heart disease were divided into single-vessel subgroup(n=73) ,double vessel lesion subgroup(n=72) ,three branch lesions subgroup (n=51) .The relationship between FERHDL and coronary artery disease were analyzed .Results The FERHDL of CHD group was significantly higher than that in the control group ,the difference was statistically significant (P<0 .05) .It was a tendency that the FERHDL increased with coronary lesions increasing (P<0 .05) .The FERHDL was significant independent correlated with the low density lipoprotein cholesterol b-C(LDLb-C) ,triglycerides(TG) ,high density lipoprotein cholesterol 2-C(HDL2-C) ,high density lipoprotein cholesterol C(HDL-C) .FERHDL was positively correlated with LDLb-C(r=8 .473 ,P=0 .000) ,TG(r=0 .714 ,P=0 .002) and negatively correlated with HDL2-C(r= -0 .692 ,P=0 .024)、HDL-C(r= -0 .829 ,P=0 .008) .Conclusion The value of FERHDL was significantly increased in CHD patients and correlated with the aggravation severity of the CHD .The change of FERHDL was significant correlated with particle size of HDL and LDL particle size .

Objective To study the clinical characteristics and the related factors of elderly arrhythmia.Methods 658 elderly patients with cardiac arrhythmia who were confirmed by the conventional ECG or Holter were chosen.Their arrhythmia type and related factors were analyzed.Results Among 658 cases of elderly patients,atrial fibrillation accounted for the highest rate(19.0％,241/1 266),followed by ventricular contraction of 17.0％ (215/ 1 266).The detection rate of sinus arrhythmia,ventricular arrhythmia was significantly different between ≥ 80 age group and ＜ 80 years old group of elderly patients (P ＜ 0.05).The 658 elderly patients had a total of 976 kinds of underlying disease,every elderly patient had one or more than one underlying disease.The top five underlying diseases were hypertension 18.6％ (182/976),coronary heart disease 16.9％ (165/976),chronic obstructive pulmonary disease 15.1％ (147/976),diabetes 14.3％ (140/976),malignant tumors 11.1％ (108/976),other underlying disease 24.0％ (234/976).In ≥ 80-years-old group,50.8％ (123/242) patients complicated with a variety of underlying diseases,which was significantly higher than that of ＜ 80-years-old group 24.5％ (102/416) (P ＜ 0.05).Conchluion Elderly patients due to the presence of different levels of underlying diseases and function degradation,prone to a variety of different types of arrhythmias,which should attract enough attention in clinical diagnosis and treatment,early detection and early intervention,in order to improve the quality of life of elderly patients.

Objective To investigate the possible influence of Lewis B expression in Helicobacter pylori (H.pylori) on bacterial adhesion property, and determine the relationship between babA 2 gene in H.pylori and peptic ulcer. Methods The bacterial adhesion property in a total of 78 H.pylori strains was performed using adherence assay in vitro, and the frequency of babA 2 gene was determined by polymerase chain reaction (PCR). Results Among 47 H.pylori strains isolated from peptic ulcer patients, 18 (38.3%) were positive for babA 2 gene, while babA 2 was positive in 14 (45.2%) of 31 strains isolated from non ulcer dyspepsia patients ( P =0.427). Among 31 H.pylori strains expressing Lewis B, 24 (77.4%) were positive for adherence assay, compared with 38 (80.9%) of 47 H.pylori strains without expression of Lewis B ( P =0.463). Conclusions (1) There is no association between babA 2 status in H.pylori strain and peptic ulcer in our population; (2) The expression of Lewis B in H.pylori does not interfere with bacterial adhesion property, and thus supports that the gastric epithelium is the receptor for Lewis B of H.pylori.

In order to study the significance of CD276 and CD133 in the development and progression of colorectal cancer (CRC),the expression of CD276 and CD133 was detected by immunohistochemistry in CRC and precancerous lesions.The results showed that the intensity of CD276 and CD133 in CRC samples was higher than that in adenoma group and non-adenoma group.CD276 and CD133 single and double positive expression were significantly correlated with CRC lymph node metastasis,distant metastasis and survival.CD276 and CD133 are significantly correlated to the development and progression of CRC and associated with poor prognosis.
