Comparison of the value of LDL-C and non-HDL-C in differential diagnosis of familial hypertriglyceridemia and familial combined hyperlipidemia / 西安交通大学学报(医学版)

Objective To evaluate the value of low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) in differential diagnosis of familial hypertriglyceridemia (FHTG) and familial combined hyperlipidemia (FCHL).Methods We recruited 9 FHTG pedigrees (94 subjects) and 24 FCHL pedigrees (94 subjects) and then divided them into affected groups and non-affected groups according to lipid abnormality.Another 10 normal control pedigrees (57 subjects) served as controls.We compared the routine lipid levels such as triglyceride (TAG),total cholesterol (TC),HDL-C and LDL-C and non-HDL-C between the groups.After stratification based on TAG level,we observed the relationship between LDL-C and non-HDL-C.Last we confirmed and analyzed the cut-off value of differential diagnosis between FHTG and FCHL with receiver operating characteristic (ROC) curve.Results The levels of TAG,TC,and non-HDL-C were significantly higher in the affected group of FHTG than in the non-affected group of FHTG and the normal group (P＜0.01 or P＜0.05).The levels of TAG,TC,HDL-C,LDL-C and non-tHDL-C wcrc significantly higher in the affected group of FCHL than in the non-affected group of FCHL and the normal group (P＜0.01 or P＜0.05).The levels of TAG were significantly higher (P＜0.01) while TC,HDL-C,LDL-C and non-HDL-C levels were significantly lower (P＜ 0.01 or P＜0.05) in the affected group of FHTG than in the affected group of FCHL.The association between LDL-C and non-HDL-C was positive both in FHTG and FCHL,but the relationship became weaker as TAG level increased.The cut-off value of LDL-C and non-HDL-C was 3.575 mmol/L and 4.525 mmol/L,respectively.Conclusion In addition to the routinely used lipid indexes,non-HDL-C may be a new index for differential diagnosis of FHTG and FCHL,and may be superior to LDL-C in this regard.

The relationship of tumor marker and CD4+T cells before and after radiotherapy on patients / 国际检验医学杂志

Objective The study is aimed to research into the effect of CD4+ T cells on patients with severe advanced breast cancer under radiotherapy that cannot be treated with surgery ,by observing the variation of CEA ,AFP ,CA125 and CA15‐3 before and after the radiotherapy applied .Methods We identified the CEA ,AFP ,CA125 and CA15‐3 densities in blood serum for a group of 38 patients with advanced breast cancer and a group of 30 normal people with chemiluminescence immune assay ,and we deter‐mined the CD3+ ,CD4+ ,CD8+ T percentage in peripheral blood and the ratio of CD4+ /CD8+ with flow cytometry .Results The group with normal CD4+ T percentage went through a decreased in CEA ,AFP ,CA125 ,CA15‐3 densities after the radiotherapy ,and the variation was significant(P<0 .05) .The group of people with abnormal CD4+ T percentage go through CEA ,CA15‐3 densities decrease after the radiotherapy ,and the variation was statistically significant(P< 0 .05) .Conclusion For those with advanced breast cancer and cannot be treated with surgery ,the influence of radiotherapy on CEA ,AFP ,CA125 ,CA15‐3 densities is significant in the group of patients with CD4+ T percentage ,adn has better therapeutic effect .

Clinical analysis on pregnant outcomes of gravidas with positive urine glucose / 国际检验医学杂志

Objective To study the effects of positive urine glucose on maternal pregnancy.Methods A total of 1 338 pregnant women were tested urine glucose.On the basis of their urine-glucose level,two groups were devided:experimental,68 cases of posi-tive urine-glucose gravidas,control group,199 cases of negative urine-glucose gravidas.Analyze on the outcome of pregnancy of the two groups.Results Compared between positive group and control group,the incidence of died(abnormal)fetus,gestational hyper-tension,abnormal amniotic fluid,fetal distress,and fetal macrosomia were not statistically different(P >0.05),but the incidence of premature rupture of membranes was statistically different (P <0.05 ).Conclusion Positive glucose urine of gravidas might in-crease the risk of premature rupture of membranes,positive urine glucose detected during pregnancy should be highly valued.

The epidemiology and risk factor of dyslipidemia for people in multiple physical examination center in Lanzhou / 国际检验医学杂志

Objective To explore the status and risk factors of the dyslipidemia among health examination population of Lanzhou for providing the intervention measures .Methods According to the stratified cluster random sampling method ,4 505 health exami-nation individuals were recruited for the study from 5 hospitals in the Lanzhou region through questionnaire ,biochemical analysis . Results Prevalence of dyslipidemia of the population was 45 .79% ,high TG was the main type .The level of serum TC ,TG ,HDL-C and LDL-C were (5 .27 ± 1 .08) ,(1 .74 ± 1 .38) ,(1 .41 ± 0 .43) and (2 .83 ± 0 .82)mmol/L .The prevalence was 53 .49% in male , and 34 .93% in female .The prevalence was higher among the group of 35- <45 years old for male and 55- <65 years old for fe-male .The level of HDL-C was low among young people .There was aggregation of risk factors among the participants with dyslipi-demia .Non-conditional logistic regression analysis showed that the risk factors were age (OR=1 .701) ,overweight (OR=5 .560) , abdominal obesity(OR=2 .398) ,smoking(OR=0 .545) ,intake of greasy diet(OR=5 .313) ,sleep quality(OR=2 .005) and diastolic blood pressure(OR=3 .061) .Conclusion Lipid disorders becomes a serious problem in the health examination population ,measures such as rational diet ,weight control ,sleep improvement ,pressure control and quiting smoking must be taken .

Objective The study aimed to assess the relationship between the plasma resistin,obesity and insulin resistance and nonalcoholic fatty liver disease(NAFLD).Methods We measured fasting plasma resistin in 60 NAFLD patients and 28 matched normal control subjects from Oct.2005 to Feb.2006.The level of plasma resistin was measured by ELISA method.Insulin resistance by homeostasis model(HOMA),height,weight,waist circumstance,hip girth,waist to hip ratio(WHR),body mass index(BMI),blood pressure,blood glucose,total cholesterol,triglyceride,HDL-cholesterol,LDL-cholesterol,aspartate aminotransferase(AST),alanine aminotransferase(ALT)and fasting insulin were measured as well.Results Plasma resistin levels were higher in NAFLD patients as compared to controls(8.56?2.5 vs 6.39?2.81,P

Experimental and clinical study on diagnosis of acute intestinal ischemia in early stage / 中国普通外科杂志

ObjectiveTo study the diagnostic value of alteration of serum enzyme in acute intestinal ischemia(AII). MethodsChanges of serum levels of CPK, CKMB, LDH, LA, CRP and CO2CP of venous blood of 40 rabbits and 53 patients in different ischemia conditions at different time before and after operation were measured to determine the relationship between the changes and ischemia degree of intestine. ResultsThe serum levels of CPK, CKMB, LDH, LA and CRP increased gradually with the severity of AII and decreased with the improvement of AII, but CO2CP was the reverse.The 6 assay values mentioned above in animals of AII compared with the control group, and in patients in pretreatment compared with the control group, and in reversible intestinal necrosis compared with irreversible intestinal necrosis, and in nonoperation group 1 h after hospitalization compared with reversible intestinal necrosis group 2 h before operation(except CO2CP)all had remarkable difference(P
