Objective To investigate the relationship between dyslipidemia and diabetic retinopathy in non-insulin-dependent diabetes mellitus（NIDDM） patients． Methods In 55 health controls，60 NIDDM patients with DR and 75 NIDDM patients without DR，the plasma total cholesterol（TC），triglycerides（TG），high-density lipoprotein（HDL）and HDL subfractions，fasting plasma glucose（FPG），fasting plasma insulin（FINS）and glycosylated hemogolbin（HbA 1C）were measured，and the plasma lowdensity lipoprotein （LDL） and very lowdensity lipoprotein（VLDL）were caculated． Results In NIDDM patients with DR，the TC，LDL，FPG，HbA 1C and duration of NIDDM were higher or longer than those in NIDDM patients without DR．Moreover，the TC，LDL，FPG、FINS、HbA 1C and dutation of NIDDM were increased or lengthened in NIDDM patients with proliferative DR as compared with those with backgroud DR．The correlation analysis showed the severity of DR was positively correlated with TC，LDL，HbA 1C and duration of NIDDM． Conclusion Dyslipidemia may play some role in the onset and development of DR． (Chin J Ocul Fundus Dis,1998,14:21-23)
ObjectiveTo investigate the role of apelin, glycosylated hemoglobin (HbA1c), cholesterol (TC), triglyceride (TG), High density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC) in the development and progress of diabetic retinopathy (DR). MethodsThe serum concentration of apelin, HbA1c, TC, TG, HDLC and LDLC were measured in 30 normal control subjects and 90 patients with type 2 diabetic mellitus, including 30 cases without DR (NDR), 30 with non-proliferative DR (NPDR), 30 with proliferative DR (PDR). These data were analyzed by SPSS for windows 13.0. ResultsThe serum concentration of apelin, HbA1c, TC, HDLC, LDLC were significantly higher in NDR, NPDR, PDR group than those in control group (F=403.06, 5.45, 4.27, 201.56, 4.90;P < 0.05). The serum concentration of TG has no significantly difference (F=2.19, P > 0.05). The serum concentration of apelin, HbA1c, TC, LDLC were significantly higher in NDR, NPDR, PDR group than those in control group (t=0.30, 0.58, 0.79;P < 0.05), the serum concentration of HDLC were significantly lower than those in control group(t=0.79, P < 0.01). There were significantly positive correlation between the progression of DR and the serum concentration of apelin, HbA1c, TC, LDLC(r=0.962, 0.562, 0.935;P < 0.05). There were significantly negative correlation between the progression of DR and the serum concentration of HDLC(r=-0.753, P < 0.01). There were correlation between apelin and HbA1c, LDLC and HDLC(r=0.956, 0.741, -0.691;P < 0.01). ConclusionOur data demonstrated that serum apelin levels increased significantly in patients with diabetic retinopathy, and are closely related to blood sugar, blood lipid metabolic abnormalities.
Objective To analyze the prevalence and influencing factors of dyslipidemia among permanent residents in Longquanyi district of Chengdu for prevention and control of dyslipidemia. Methods Permanent residents in Longquanyi district were selected as research objects by convenient sampling method between November 2021 and February 2022. The dyslipidemia rate in the population was analyzed, and the influencing factors of dyslipidemia were analyzed by univariate and multivariate logistic regression. Results A total of 11 408 permanent residents were included. Among them, 3650 people had dyslipidemia, with a prevalence rate of 32.00% (3650/11408). The prevalence rates of high total cholesterol, high triglyceride, high low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol were 19.30% (2 202/11 408), 13.38% (1 526/11 408), 5.05% (576/11 408) and 0.73% (83/11 408), respectively. Multivariate logistic regression analysis showed that female, age≥30 years old, drinking, overweight / obesity, hypertension, diabetes and hyperuricemia were independent risk factors of dyslipidemia among permanent residents (P<0.05). Conclusions The prevalence of dyslipidemia in Longquanyi district is high, mainly with high total cholesterol and high triglyceride. Gender, age, drinking, body mass index, and the levels of blood pressure, blood glucose and blood uric acid are the factors affecting the incidence of dyslipidemia among permanent residents. Early intervention for high-risk groups with dyslipidemia should be adopted to effectively reduce the risk and burden of dyslipidemia.
ObjectiveTo investigate the relationship between thyroid stimulating hormone (TSH) and the blood lipid level in patients with subclinical hypothyroidism (SCH). MethodsWe carried out a retrospective analysis on the clinical data of 264 patients with their first diagnosis of subclinical hypothyroidism without treatment from 2010 January to 2014 January. A total of 288 healthy controls were chosen from communities. The patients were groups based on TSH≥10.0 mU/L and 3.6 mU/L≤ TSH< 10.0 mU/L. We investigated the relationship between TSH and the level of blood lipids by analyzing liver and renal function, blood lipids, thyroid function, and thyroid peroxidase antibody (TPO-Ab) in the patients. ResultsTriglyceride (TG) and high density lipoprotein cholesterol levels were not significantly different among the three groups (P>0.05). Total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels of the group with TSH≥10 mU/L were respectively (5.93±1.12) and (3.82±1.11) mmol/L, which were significantly higher than those in the controls[(4.43±1.12) and (2.66±0.43) mmol/L] (P<0.05). TC, TG and LDL-C levels of the group with 3.6 mU/L≤ TSH< 10.0 mU/L were higher than the controls, but the differences were not significant (P>0.05). After thyroid hormone replacement therapy within 12 weeks, TG, LDL-C, and TC levels of TPO-Ab positive patients with subclinical hypothyroidism (n=112) were respectively (4.62±1.03), (2.97±0.52), and (1.17±0.62) mmol/L, which were significantly lower than those levels before treatment[(5.43±1.18), (3.62±0.58), and (2.03±0.71) mmol/L] (P<0.05). ConclusionThe disorder of lipid metabolism exists in patients with subclinical hypothyroidism. Especially, the level of TSH greater than or equal to 10 mU/L is a high risk factor for dyslipidemia. In TPO-Ab positive patients, therapy of thyroid hormone replacement can effectively improve the blood lipid abnormalities in patients with subclinical hypothyroidism, and it may be an effective measure to improve the disorder of lipid metabolism economically and effectively.
Objective To probe into disorder of plasma lipids and apolipoproteins in patients with gallstone,and their position and function in formation of gallstone. MethodsConcentration of plasma lipids and apolipoproteins in 94 healthy subjects and 161 patients with gallstones was investigated. ResultsThe gallstone group had a higher serum mean concentration of TG,Apo CⅡ,Apo CⅢ, and had a lower serum mean concentration of TC，HDLc，HDL2c，HDL3c and LDLc as compared with the control group (P＜0.01 or P＜0.05). Conclusion Higher serum mean concentration of TG，Apo CⅡ，Apo CⅢ, and lower serum mean concentration of TC, HDLc, HDL2c, HDL3c and LDLc, are characteristic of lipids metabolism and important cause of formation of gallstone.

Objective To observe the serum lipid level of patients with branch retinal vein occlusion (BRVO). Methods A total of 71 BRVO patients (BRVO group) were enrolled in this study. The patients included 31 males and 40 females, with an average age of (52.75plusmn;10.2) years. All the patients were examined for visual acuity, slit lamp ophthalmoscopy combine with preset lens, fundus color photography and fundus fluorescein angiography (FFA) examination. Seventy-two age and sex matched normal subjects were enrolled in this study as control group. The subjects included 32 males and 40 females, with an average age of (53.10plusmn;9.5) years. The BRVO and control group were divided into four subgroup which including age with ＜40 years, 40-49 years, 50-59 years and ge;60 years. The plasma cholesterol and triglyceride level of BRVO group, control group, and age subgroups of BRVO and control group were comparatively analyzed. Results The average plasma cholesterol levels were (4.529plusmn;0.100) and (4.274plusmn;0.106) mmol/L in BRVO and control group, respectively. There was no difference between two groups (t=-1.738，P＞0.05). The average triglyceride levels were (1.500plusmn;0.129) and (1.319plusmn;0.095) mmol/L in BRVO and control group, respectively. There was no difference between two groups (t=-1.135，P＞0.05). There was no difference of average plasma cholesterol (t=-1.755, 1.850, -1.892, -0.507) and triglyceride (t=0.846, -0.074, -1.288, -1.887) level in age subgroups of BRVO and control subgroup (P＞0.05). Conclusion There is no significant difference of serum lipid level between BRVO patients and controls.
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.
Objective To analyze the effects of hyperuricemia (HUA) on the prevalence of dyslipidemia in the elderly. MethodsA total of 5 990 elderly people with complete and important variables from the China Health and Retirement Longitudinal Study (CHARLS) public database in 2015 were extracted. Their blood lipids, related physiological and biochemical indices, and basic demographic information were collected. The effects of HUA on the prevalence of dyslipidemia in the elderly were analyzed using the probit model, and empirical analysis was performed using the propensity score matching method (PSM). Results Among the 5 990 subjects, 13.6% of the elderly had HUA and the prevalence of dyslipidemia was 37.5%. After correcting the endogeneity among variables, the probability of dyslipidemia in elderly patients with HUA increased by 9.5%-11.7% (P<0.01), in which the probability of high triglyceridemia (TG), high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), and low high-density lipoprotein cholesterol (HDL-C) increased by 10.4%-11.5% (P<0.01), 2.7%-3.8% (P<0.01), 1.7%-2.3% (P<0.05), and 4.3%-4.9% (P<0.05), respectively. Conclusion HUA is associated with various types of dyslipidemia, among which its relationship with high TG and low HDL-C is strong. Targeted interventions should be taken for elderly HUA patients, aiming to reduce the rate of dyslipidemia and promote the goal of "healthy ageing" in China.
