Dyslipidemia plays an important role in the pathogenesis of diabetic retinopathy (DR).Apreliminary study found that low-density lipoprotein cholesterol, apolipoprotein (Apo)Band ApoB/ Apo A1 ratio were positively correlated with DR, while high-density lipoprotein cholesterol, Apo A1 was negatively correlated with DR and proliferative DR. Reducing the blood fats to be helpful to DR control. However, the mechanism of hyperlipidemia in the pathogenesis of DR, the reason of dyslipidemia in diabetic patients and the interaction between hyperglycemia and hyperlipidemia in DR are not clear yet. Moreover, there is no predictive indicators related to blood lipid for DR. Understanding the relationship between dyslipidemia and DR can provide definite evidence for fat-reducing therapy for DR control.

Methods A total of 192 senile people form May 2008 to October 2009 were investigated. There were 141 patients with diabetes, in whom 68 were with cardiovascular and cor, cerebrovascular diseases, 73 were with diabetes only.There were 51 control subjects. The data of serum cystatin C, hs-CRP, TC, TG, HDL-C and LDL-C were analyzed. Results Serum cystatin C of elderly men was lower than that in elderly women, but no signifcant correlation between them was found (Pgt;0.05). Serum cystatin C, hs-CRP, TC, TG and LDL-C was higher, and HDL-C was lower in male and female diabetes subjects with cardiovascular and cor, cerebrovascullar diseases, than that in control subjects (Plt;0.05). Serum hs-CRP, TC and TG were higher in the elderly with diabetes only, than that in control subjects (Plt;0.05). LDL-C was higher in senile women with diabetes only, than that in female control subjects (Plt;0.05). Serum cystatin C with LDL-C in elderly women with diabetes only, with FPG in female diabetes subjects with cardiovascular and cor, cerebrovascular diseases had position correlation (Plt;0.05). No correlation were observed between serum cystatin C and hs-CRP in male and female diabetes subjects, and lipid in male diabetes subjects. Conclusions We speculate that high serum lipid, high glucose and low level of inflammation may result in increasing of serum cystatin C in senily people with diabetes. The influence of serum lipid on serum cystatin C may be different in male and female senile people.Along with atherosclerotic aggravating, the level of serum cystatin C was increasing.
目的 探討川崎病（Kawasaki disease，KD）患兒血脂代謝與冠狀動脈病變之間的關系。 方法 納入2007年1月-2009年10月住院治療的82例KD患兒，檢測治療前后血總膽固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL-C）、低密度脂蛋白（LDL-C）、極低密度脂蛋白（VLDL-C）、載脂蛋白A1（ApoA1）及載脂蛋白B100（ApoB100）水平。選取50例健康兒童作為對照。KD患兒在治療前行超聲心動圖檢查，根據超聲心動圖顯示將KD組再分為冠狀動脈病變組（CAL組，n=31）和非冠狀動脈病變組（NCAL，n=51）。 結果 治療前，KD患兒TC、ApoA1、HDLC降低，TG、LDL-C升高，與正常兒童相比有統計學意義（Plt;0.05）。KD患兒CAL組較NCAL組變化更明顯，有統計學意義（Plt;0.05）。VLDL-C和ApoB100水平KD患兒與正常兒童比較、NCAL組與CAL組比較變化均不明顯（Pgt;0.05）。治療后與治療前相比，NCAL組TC、TG、HDL-C、LDL-C、ApoA1恢復正常（Plt;0.05）），而CAL組僅TC、LDL-C、ApoA1恢復正常（Plt;0.05）。 結論 KD患兒存在血脂代謝紊亂，TC、TG、HDL-C、LDL-C、ApoA1與冠狀動脈的損害有關，應早期進行干預。
The present study was designed to elucidate the role of apoE polymorphism in the lithogenesis of cholecystolithiasis and to explore the hereditary pathogenesis of the disease. Polymerase Chain Reaction (PRC) was used as researching apoE phenotypes and allele frequencies in patients with gallstones (n=87) and in controls (n=50), and the fasting serum lipids of subjects were also measured. The characteristics of lipid variants were analysed among the patients with different apoE phenotypes. The results showed that the levels of TG (1.43mmol/L), VLDL-C(0.68mmol/L) in E2/3 patients were greatly higher than those in E2/3 controls (1.06mmol/L, Ｐ＜0.05 and 0.48mmol/L, Ｐ＜0.05), and LDL-C (1.41mmol/L) was markably lower in E2/3 patients than that in controls (2.04mmol/L, Ｐ＜0.05). The levels of serum lipids decreased significantly in E3/3 patients with HDL-C (0.89mmol/L), HDL2-C (0.49mmol/L), HDL3-C (0.39mmol/L), and compared with those in E3/3 controls (1.28mmol/L Ｐ＜0.05, 0.73mmol/L Ｐ＜0.001 and 0.55mmol/L Ｐ＜0.001). In E3/4 patients there were only slight changes of VLDL-C, LDL-C level. The results suggest that the average level of serum lipids in the same apoE phenotype patients with gallstones is higher than that in controls, and the different apoE phenotypes patients with gallstones have different characteristics of dyslipidemia. ε2 allele is probably one of the dangerous factor in the lithogenesis of cholecystolithiasis.
ObjectiveTo investigate the prevalence status and characteristics of dyslipidemia and cardiovascular risk factors in urban communities of Chengdu city. MethodsBy cluster sampling, a population of 994 inhabitants were selected from 14 urban communities in Chengdu city between February and October 2010. We investigated patients between 35-70 years old who lived in the area over 2 years, by using questionnaires survey, physical examination, and laboratory tests. According to the age, the respondents were divided into three groups: young group ( ≤ 44 years old), middle-aged group (45-59 years old) and elderly group ( ≥ 60 years old). We further investigated the major cardiovascular risk factors for hyperlipidemic patients. ResultsThe prevalence of dyslipidemia in Chengdu urban area was 28.47% (283/994), and standardized prevalence rate was 24.65% (male, 24.68%; female, 30.91%). The prevalence rate between male and female had significant diTherence (χ2=4.513, P=0.034). Female elderly group and middle-aged group had a significantly higher prevalence than the young group (P<0.05), while the male prevalence had no statistical diTherences among all age groups (P>0.05). Hypertension was most common in patients with dyslipidemia (male, 50.04%; female, 52.41%) followed by diabetes and coronary heart disease. There was no difference between male and female in the prevalence of dyslipidemia accompanied hypertension, history of stoke and coronary heart disease, abdominal obesity,or obesity (P>0.05). Higher prevalence with smoking and drinking was in male patients (P<0.05). ConclusionThe prevalence of dyslipidemia is relatively high in urban communities of Chengdu city. According to the region of hyperlipemia epidemiological characteristics and risk factors, by using comprehensive intervention measures, we can reduce the prevalence of dyslipidemia.
