OBJECTIVE:
To explore the association of serum level of apolipoprotein M with disease activity in systemic lupus erythematosus (SLE).
METHODS:
A total of 65 patients with SLE, who came to Second Xiangya Hospital for treatment from April to November in 2013 (SLE group) and 120 age-and sex-matched controls (control group) were studied. The SLE group was further divided into three groups according to systemic lupus erythematosus disease activity index (SLEDAI): a mild activity group, a moderate activity group and a severe activity group (n=16, 16, 33, respectively). The control group was also divided into a disease control group (n=60) and a healthy control group (n=60). The serum levels of apo M were measured by enzyme-linked immunosorbent assay (ELISA). Other indicators including TC, TG, HDL, LDL, apo A1, apo B, and anti-dsDNA antibody were detected. The correlation between SLEDAI or anti-dsDNA antibody and apo M was assessed.
RESULTS:
Compared with the healthy control group, the expression levels of apo M and HDL were decreased significantly (both P<0.05), and the expression levels of anti-dsDNA antibody, TG, apo B were increased significantly in the SLE group (all P<0.05). Comparison among the three subgroups, no significant differences in apo M were found (all P>0.05). The serum concentration of apo M was significant negatively correlated with SLEDAI and anti-dsDNA antibody (r=-0.551, -0.562, both P<0.01).
CONCLUSION
Compared with the healthy control group, the serum levels of apo M in patients with SLE are significantly decreased. The apo M is closely correlated with disease activity of SLE and it might be used as an indicator to monitor the disease activity of SLE.

2.Association of Serum Apolipoprotein B with the Increased Risk of Diabetes in Korean Men.
Clinical Nutrition Research 2016;5(3):204-212
This study aimed to investigate the association of Apolipoprotein B (ApoB) with the risk of diabetes in Koreans. Korean men (n = 790, 40-79 years) who had been never diagnosed for diabetes before participating were enrolled. Subjects were categorized into normal fasting glucose (NFG, n = 519), impaired fasting glucose (IFG, n = 188) and newly-onset diabetes (n = 83) according to fasting glucose levels. Age was not significantly different among the subgroups. Mean values of BMI, waist circumference, Blood pressure(BP), triglyceride, non-HDL cholesterol were significantly higher in IFG or newly-onset diabetic subjects compared to NFG subjects. The levels of glucose, insulin, free fatty acid, insulin resistance and ApoB were highest in diabetic patients and lowest in NFG subjects. According to ApoB level, subjects were divided into two groups (high-ApoB group: ≥ 87.0 mg/dL vs. low-ApoB group: < 87.0 mg/dL). The risk of diabetes was higher in the high-ApoB group than the low-ApoB group [OR₀: 2.392, (95% CI: 1.470-3.893), P₀< 0.001]. This association was maintained after adjusted for age and BMI [OR₁: 2.228, (95% CI: 1.362-3.646), P₁ = 0.001] and further adjustment for blood pressure, triglyceride, HDL-cholesterol, LDL-cholesterol, non-HDL-cholesterol, ApoA1 and adiponectin [OR₂: 1.984, (95% CI: 1.001-4.064), P₂ = 0.049]. The association was much greater in subjects with metabolic syndrome (MetS) [OR₁: 2.805 (95% CI: 1.137-5.737), P₁ = 0.005] than in those without [OR₁: 1.917 (95% CI: 0.989-3.718), P₁ = 0.054]. After 3-month, further investigation was randomly performed in subjects with NFG or IFG who agreed to reinvestigation. Multiple stepwise regression analysis revealed that net change of ApoB levels was a main contributor to the net change of glucose levels (standardized b-coefficient: 0.315, p = 0.002). In conclusion, ApoB levels are closely associated with the increased risk of diabetes in Korean men.

PURPOSE: We studied to find out apo-E genotype polymorphism in minimal change nephrotic syndrome(MCNS) and IgA nephropathy(IgAN) and to determine the relationship between apo-E genotype and clinical course of MCNS. MATERIALS AND METHOD: 43 MCNS patients and 15 IgAN patients were examined for apo-E polymorphism. 50 healthy blood donors were examined for apo-E genotype as control. Genomic DNA was prepared from peripheral blood leukocytes according to standard procedures. RESULTS: As compared with control group, e4 allele frequency was significantly increased in MCNS (P<0.01). However, in IgAN e2 allele frequency, however, was 2.6 times higher than normal control (P<0.01). The frequency of e4 allele of frequent relapser group was 4.6 times higher than normal control and was 2 times higher than infrequent relapser group. CONCLUSION: We think that apo-E typing might be one of the parameters, which should be considered to predict the course of MCNS in children. MCNS with risky HLA profile and E4/4 genotype could indicate the need for a longer steroid dministration. And apo-E genotype needs to be considered for the evaluation of therapeutic responses to other drugs.

OBJECTIVE: Associations of vascular risk/disease or apolipoprotein E epsilon4(APOE4) with geriatric depression has been unclear at a population level. This study aimed to evaluate whether there would be interactions of vascular risk/disease and APOE4 on depression in a Korean elderly population. METHODS: 732 community residents aged 65 or over were assessed for depression(GMS), information on vascular risk/disease(reported stroke, transient ishemic attack, heart disease, hypertension, diabetes, smoking), examinations for vascular risk/disease(blood pressure, blood tests for glucose and lipid profiles, body size), APOE genotypes, demographic characteristics(age, gender, education), physical health, and cognitive function(MMSE). RESULTS: Previous stroke and lower level of high density lipoprotein(HDL) cholesterol were significantly associated with geriatric depression independent of demographic characteristics, physical illnesses, and cognitive function. These associations were statistically significant only in those with APOE4, although the interaction terms didn't reach to statistical significance. CONCLUSION: Associations between vascular risk/disease and geriatric depression might be more prominent in those with APOE4. However further research would be needed to clarify this issue.

OBJECTIVETo study the effects of local vibration on blood-lipids and whole blood viscosity.
METHODSThe total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), whole blood viscosity, apolipoprotein (Apo-), red blood cell (RBC), platelet (PLT), mean corpuscular volume (MCV), serum-protein, postprandial blood sugar (PBS), and serum-protein of experimental and control workers were detected. The difference of the means and abnormal rates of two groups were compared.
RESULTSThe means of TG, TC, HDL in exposed group [(1.01 +/- 0.85), (3.25 +/- 0.61), (1.14 +/- 0.20) mmol/L respectively] were significantly lower than that of control group [(1.89 +/- 1.47), (3.87 +/- 0.82), (1.22 +/- 0.26) mmol/L, respectively, P < 0.01 or P < 0.05]. Apo-A was also decreased [(1.13 +/- 0.29) g/L vs (1.23 +/- 0.16) g/L, P < 0.01]. The mean of whole blood viscosity were significantly increased in exposed group [(2.76 +/- 0.42) mPa.s vs (2.54 +/- 0.33) mPa.s, P < 0.01]. The abnormal rate of Apo-A was significantly higher in exposed group (23.30%) than that in control (4.50%, P < 0.01).
CONCLUSIONLocal vibration may induce decrease in blood lipids, increase in blood viscosity and changes in some other blood parameters.

Chinese Journal of Applied Physiology 2003;19(3):295-297
AIMTo investigate the effects of serum testosterone level on plasms lipid and apolipoprotein spectrum in orchiectomized rabbits.
METHODS40 male New Zealand rabbits were divided randomly into five groups (n = 8): control group, sham (castration), castration group (castration), hypotestosteronemia group (castration plus low dose testosterone replacement), physiological level group (castration plus moderate testosterone replacement), and hypertestosteronemia group (castration plus large dose testosterone replacement). The rabbits in hypotestosteronemia, physiological level and hypertestosteronemia group were injected testosterone undecanoate 3 mg/kg, 6 mg/kg, and 12 mg/kg, respectively and the remaining control, and castration rabbits, vehicle only. 8 weeks after initiation of the experiment, blood was collected for determination of serum levels of total testosterone (TT), estradiol (E2), lipids, lipoproteins, apolipoproteins.
RESULTSAfter castration, the serum level of TT decreased significantly to the lowest level, and TU replacement increased serum TT level depending on dose. The low dose of TU increased serum TT level slightly and produced a hypotestosteronemia model, the moderate dose of TU increased serum TT level near to normal level and produced a physiological model, the large dose of TU increased serum TT level significantly to the highest level and produced a hypertestosteronemia model. The tatol cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB) were significantly increased in hypotestosteronemia and hypertestosteronemia rabbits and significantly decreased in physiological serum testosterone rabbits.
CONCLUSIONTestosterone, at physiological level has good effect on the serum lipids, lipoproteins, apolipoproteins in the castration rabbits, and the hypotestosteronemia and hypertestosteronemia has bad effect.

PURPOSE: This study was designed to evaluate the incidence of complication in severely obese children and to determine whether the difference of Lp (a) between severely obese children and normal control group exists. METHODS: Body weight, height and obesity index were measured in 5885 (M:F= 3089:2796) elementary school children. Eight eight (M:F=63:25) were selected as severely obese children. Of the 88 children, 74 agreed to venous puncture for the measurement of serum glucose, total cholesterol, AST, ALT, HDL-cholesterol, apo A1, apo B and Lp (a). Blood pressure and atherogenic index were also checked. Twenty nine children were selected for the control group. RESULTS: The prevalence of severe obesity in elementary school children was 1.5%. Of 74 severely obese children, serum total cholesterol was over 200mg/dl in 16.2%, and HDL cholesterol below 40mg/dl in 47.3%. Atherogenic index was over 3 in 60.8%. The incidence of hypertension and fatty liver was 6.8% and 13.5%, respectively. DM was not found. The levels of total cholesterol, ALT, HDL cholesterol and atherogenic index in severely obese group differed significantly from those of control group. There were no significant differences in apolipoprotein levels between severely obese and control group. CONCLUSIONS: The incidence of complication in severely obese children is considerably high. We need systemic program about obesity prevention and management, and individualized approaches to prevention have to be applied. It seems that severe obesity doesn't directly influence on the levels of Lp (a) and apolipoproteins.

PURPOSE: We investigated how serum low-density lipoprotein (LDL) level is related to various isoforms of apolipoprotein (ApoE) polymorphism in association with obesity and metabolic syndrome. MATERIALS AND METHODS: We gathered total 332 sample of postmenopausal Korean women and analyzed ApoE isoforms, serum lipid level including LDL, blood pressure, fasting glucose, and anthropometry. The relationship between ApoE isoforms and serum lipid level, metabolic syndrome, and obesity was investigated. RESULTS: Six ApoE isoforms were found, ApoE2 [E2/2 (n=1), E2/3 (n=54), E2/4 (n=14)], ApoE3 (E3/3, n=200), ApoE4 [E3/4 (n=55), and E4/4 (n=8)]. The prevalence of metabolic syndrome and obesity showed higher ApoE3 isoform than that of other isoforms. In additon, ApoE3 isoform was related to higher serum LDL and total cholesterol level than to ApoE2 isoform. The odds ratio of having the highest LDL cholesterol quartile in ApoE3 with obesity, compared to ApoE2 without obesity, was 3.46 [95% confidence interval (CI); 1.07-11.14, p=0.037], and odds ratio of ApoE3 with metabolic syndrome compared to ApoE2 without metabolic syndrome was 5.06 (95% CI; 1.14-22.29, p=0.037). Serum LDL cholesterol was positively associated with obesity or metabolic syndrome in ApoE3 isoform. CONCLUSION: This study suggests that obesity or metabolic syndrome risk should be effectively managed in ApoE3 isomform groups to reduce serum LDL in postmenopausal Korean women.

OBJECTIVETo explore the relationship between serum apolipoprotein A5 (ApoA5) and lipid profile or high sensitive C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS).
METHODSSerum apoA5 and hs-CRP levels were measured by ELISA and immunoturbidimetry in control subjects (n = 232), patients with stable angina (SA, n = 127), unstable angina (UA, n = 116) and acute myocardial infarction (AMI, n = 112). Triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were also measured.
RESULTSCompared with controls [(108.7 +/- 23.2) microg/L] and SA patients [(78.3 +/- 20.2) microg/L], serum ApoA5 level was significantly increased in UA [(340.6 +/- 63.5) microg/L] and AMI patients [(373.2 +/- 73.8) microg/L] (all P < 0.05). ApoA5 was positively correlated with TG (r = 0.63 and 0.67, respectively, all P < 0.05) and hs-CRP (r = 0.57 and 0.55, respectively, all P < 0.05) in UA and AMI patients but there were no significant correlations between ApoA5 and TC, HDL-C and LDL-C in ACS patients (all P > 0.05).
CONCLUSIONIncreased serum apoA5 level and the positive correlation between ApoA5 and serum TG and hs-CRP in ACS patients might reflect increased inflammation responses in ACS patients.

OBJECTIVETo study the association of ORMDL3 single nucleotide polymorphisms (SNP) with lysophosphatidylcholine (LysoPC) and apolipoprotein B (apoB) levels.
METHODSA total of 300 children diagnosed with bronchial asthma between January 2010 and December 2012 were selected for the asthma group, and 298 children diagnosed with upper respiratory tract infection in the same period were selected for the control group. Serum LysoPC and apoB levels were measured using enzyme-linked immunosorbent assay. Genotype analysis was performed using the TaqMan probe.
RESULTSLysoPC and apoB levels were significantly higher in the asthma group than in the control group (P<0.01). Among children with various genotypes of ORMDL3 gene at locus rs12603332, the asthma group had significantly higher LysoPC and apoB levels than the control group (P<0.01). Among the children with asthma, those with CC genotype had significantly higher LysoPC and apoB levels than those with CT and TT genotypes (P<0.01).
CONCLUSIONSLysoPC and apoB may intervene in the pathological process of asthma. Pro-inflammatory gene ORMDL3 SNP rs12603332 may be associated with high LysoPC and apoB levels, which leads to the occurrence of childhood asthma.
