Correlations of systolic blood pressure with uric acid, blood lipid and blood glucose / 预防医学

Objective@#To analyze the correlations of systolic blood pressure (SBP) with uric acid, blood lipid and blood glucose in adults, so as to provide the evidence for blood pressure management and early prevention of cardiovascular diseases. @*Methods@# Based on the China Health and Nutrition Survey, data of participants in 2004 and 2009 was collected, including demographic characteristics, blood pressure, uric acid, blood lipid and blood glucose. Participants with SBP<140 mmHg both in 2004 and 2009 were divided into the continuously normal group, participants with SBP≥140 mmHg in 2004 and <140 mmHg in 2009 were divided into the reduced group, participants with SBP<140 mmHg in 2004 and ≥140 mmHg in 2009 were divided into the elevated group, and participants with SBP≥140 mmHg both in 2004 and 2009 were divided into the continuously high group. Multivariable logistic regression model was used to analyze the correlations of SBP with uric acid, blood lipid and blood glucose. @*Results@#A total of 5 086 subjects were included in this study with a mean age of (48.0±7.2) years, including 2 374 males (46.67%) and 2 712 women (53.33%). The median (interquartile range) of SBP was 117.00 (13.33) mmHg in the continuously normal group, 146.67 (15.33) mmHg in the reduced group, 122.67 (12.00) mmHg in the elevated group and 150.67 (18.66) mmHg in the continuously high group. Multivariable logistic regression analysis showed that compared with the continuously normal group, the reduced group was correlated with abnormal fasting blood glucose (OR=1.383, 95%CI: 1.008-1.896); the elevated group was correlated with abnormal uric acid (OR=1.495, 95%CI: 1.195-1.869), abnormal low density lipoprotein cholesterol (OR=1.226, 95%CI: 1.030-1.460), abnormal triglyceride (OR=1.446, 95%CI: 1.203-1.739) and abnormal total cholesterol (OR=1.261, 95%CI: 1.057-1.504); the continuously high group was correlated with abnormal uric acid (OR=1.603, 95%CI: 1.188-2.164), abnormal triglyceride (OR=1.619, 95%CI: 1.253-2.093) and abnormal fasting blood glucose (OR=1.565, 95%CI: 1.166-2.100), adjusting for confounding factors (gender, age, marital status, etc.).@*Conclusion@# The increase of SBP in adults were correlated with uric acid, blood lipid and blood glucose.

Relationship between atherogenic index of plasma and childhood asthma / 中国当代儿科杂志

OBJECTIVES@#To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma.@*METHODS@#This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis.@*RESULTS@#The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686).@*CONCLUSIONS@#AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

Correlation between serum cystatin C and lipid level in patients with chronic heart failure / 中南大学学报(医学版)

OBJECTIVES@#Serum cystatin C (Cys C) and blood lipid levels are related to the occurrence and development of chronic heart failure (CHF). However, there are few reports on the correlation between blood lipid level and serum Cys C level in patients with CHF. The aim of this study is to explore the correlation between serum Cys C level and blood lipid level in patients with CHF, and to provide valuable reference for clinical diagnosis and treatment of CHF.@*METHODS@#A total of 336 CHF patients who were hospitalized in the Department of Cardiovascular Medicine of Shaanxi Provincial People's Hospital from October 2017 to July 2018 were included and they were divided into a Cys C normal group (n=180) and a Cys C abnormal group (n=156) according to serum Cys C level of the patients. The general data, laboratory indicators, and cardiac ultrasound results were compared between the 2 groups. Pearson correlation analysis was used to detect the correlation between serum Cys C level and blood lipid level and other factors, and the data related to Cys C were further analyzed by multivariate logistic regression.@*RESULTS@#Compared with the Cys C normal group, patients in the Cys C abnormal group had lower left ventricular ejection fraction (LVEF) (P<0.001), older age (P=0.030), higher incidence rate of diabetes and smoking index (P=0.002 and P=0.003, respectively). The levels of serum creatinine (SCr), blood urea nitrogen (BUN), and total bilirubin (TBIL) were higher (all P<0.001), while the levels of high density lipoprotein (HDL), apolipoprotein (Apo) A, and albumin (ALB) were lower (P<0.001, P=0.001, and P=0.003, respectively) in the Cys C abnormal group. Pearson correlation analysis showed that serum Cys C level was negatively correlated with platelet count, HDL, Apo A, ALB, and LVEF. It was positively correlated with smoking index, mean platelet volume, neutrophil ratio, BUN, and TBIL (all P<0.05). The results of multivariate logistic regression analysis showed that the decreased HDL level was a risk factor for the abnormality of serum Cys C in patients with CHF (OR=0.119, P=0.003), while Apo A was not a risk factor for its abnormality (P=0.337).@*CONCLUSIONS@#HDL might be the only blood lipid index associated with abnormal serum Cys C in patients with CHF.

Cord Blood Lipid Profile of Term and Preterm Newborns in a Tertiary Hospital in South East Nigeria: Relationship with Gestational Age and Birth Weight

Background: Early-onset atherosclerosis is a marker of future cardiovascular diseases. However, indicators of early dyslipidemia for primary prevention are generally lacking in sub-Saharan Africa. This study aimed at describing the cord blood lipid profile among apparently healthy newborns in a tertiary hospital in Southeast Nigeria, and its relationship with gestational age and birth weight.Methods: Cross-sectional study of 167 consecutively recruited apparently well newborns in a tertiary hospital whose cord blood lipid profile parameters (total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL ­C), low-density lipoprotein cholesterol (LDL ­C) and very low-density lipoprotein cholesterol (VLDL ­C)) were assessed using an autoanalyzer (BiOLis 24i). Lipid variables were presented with descriptive statistics whereas their relationship with gestational age and birth weight was highlighted using Spearman's rank correlation analysis. Dunnett's T3 Post Hoc analysis was used for pairwise comparisons.Results: The 167 newborns recruited included 15 (9%) moderate preterm, 46 (27.5%) late preterm and 106 (63.5%) term babies of which 79 (47.3%) were males and 88 (52.7%) were females. The number of recruited SGA, AGA and LGA were respectively 13 (7.8%), 142 (85%), 12 (7.2%). Mode of delivery was majorly vaginal delivery (69.5%) while the rest (30.5%) was by caesarean section. The median values (in mg/dL) of TC, TG, HDL ­C, LDL ­C and VLDL ­C were 60.0, 30.5, 29.0, 25.8 and 6.1 respectively, all within the normal international ranges. Triglycerides and VLDL-C had a moderate positive correlation with gestational age (rs = 0.4;p < 0.001) and were significantly higher in small-for-gestational-age newborns. Total cholesterol, HDL ­C, and LDL-C had a weak negative correlation with gestational age and birth weight (spearman rs˂-0.3). Birth weight, gestational age, and paternal age were the common predictors of lipid profile variability.Conclusion: The finding of a significant relationship between lipid variables with gestational age and birth weight underscores the need to clinically interpret these given the relationship. The relationship with paternal age is another interesting finding which needs to be replicated and the mechanism(s) elucidated.

Factors affecting blood lipid control among residents at a high risk of atherosclerotic cardiovascular disease / 预防医学

Objective@#To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD.@*Methods@#Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model.@*Results@#A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD. @*Conclusions @#Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.

Effects of iodine excess on antioxidant capacity and blood lipid level in adult / 中华地方病学杂志

Objective:To study the effect of iodine excess on antioxidant capacity and blood lipid in adult.Methods:A survey was conducted in areas with different iodine nutrition levels in Shandong and Shanxi provinces to collect fasting morning urine and venous blood samples of adults. Urinary iodine, serum levels of superoxide dismutase(SOD), malondialdehyde (MDA), total cholesterol (TCHO), triglyceride (TG), apolipoprotein A1 (apoA1) and apolipoprotein B (apoB), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were determined. According to the median urinary iodine of the population in the investigated village, they were divided into appropriate iodine group (100-299 μg/L) and iodine excess group (≥300 μg/L) . Multiple linear regression was used to analyze the effects of iodine nutrition and other factors on oxidative stress indexes and blood lipids. Partial correlation analysis was used to analyze the relationship between iodine nutrition and oxidative stress indexes and blood lipids.Results:A total of 1 049 subjects were included, including 471 in the appropriate iodine group and 578 in the iodine excess group. The median (quartile) urinary iodine of the appropriate iodine group and the iodine excess group was 228.70 (157.02, 341.49) and 558.73 (298.06, 985.06) μg/L, respectively. The serum SOD level of the appropriate iodine group and the iodine excess group was 12.60 (10.83, 14.10) and 11.29 (9.18, 13.10) U/ml, respectively, and the difference between the groups was statistically significant ( U = 92 697.50, P < 0.001). There were statistically significant differences in serum TG, HDL-C and apoB levels between the appropriate iodine group and the iodine excess group ( U = 108 879.50, 96 613.50, 99 050.50, P < 0.05). The results of multiple linear regression showed that after excluding age, gender and body mass index (BMI), there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [standard regression coefficient ( β) = - 0.196, - 0.294, P < 0.001]. Partial correlation analysis showed that there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [correlation coefficient ( r) = - 0.16, - 0.09, P < 0.05]. Conclusion:Excessive iodine intake affects oxidative stress and lipid metabolism in human body.

Correlation analysis of hepatic steatosis, blood lipids and uric acid metabolism in elderly patients with chronic hepatitis B / 公共卫生与预防医学

Objective To analyze the correlation of hepatic steatosis with blood lipids and uric acid metabolism in elderly patients with chronic hepatitis B (CHB). Methods The clinical data of 120 patients with CHB admitted to the hospital from January to December 2021 were retrospectively analyzed. According to the presence or absence of hepatic steatosis, the patients were divided into steatosis group (n=35) and non-steatosis group (n=85). The general clinical data, serological indicators of hepatitis B virus, blood lipid and uric acid levels were compared between the two groups. The correlation of hepatic steatosis grading with blood lipids and uric acid metabolism was analyzed. Results The inflammation and fibrosis degree of liver tissues were significantly different in the two groups (P0.05). Pearson correlation analysis found that the grade of hepatic steatosis in patients with CHB was negatively correlated with liver tissue inflammation, fibrosis degree and HDL-C level (P<0.05), and positively correlated with TG and TC levels (P<0.05). Conclusion Elderly patients with CHB and hepatic steatosis have abnormal blood lipid metabolism. Hepatic steatosis will exacerbate abnormal blood lipid metabolism but not liver tissue inflammation or fibrosis degree. Clinically, attention should be paid to blood lipid monitoring of elderly patients with CHB.

Prognostic value of PCSK9 and blood lipid in patients with sepsis / 中华危重病急救医学

Objective:To investigate the prognostic value of proprotein convertase subtilisin/kexin type 9 (PCSK9) and blood lipid indexes in patients with sepsis.Methods:Patients with sepsis or septic shock who were ≥ 18 years old and met the Sepsis-3.0 diagnostic criteria admitted to the department of critical care medicine of Binzhou Medical University Hospital from January to October 2021 were enrolled. Healthy adults at the same period were selected as healthy control group. Baseline characteristics, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) score were recorded. Venous blood samples were collected within 24 hours after diagnosis, and serum PCSK9 was determined by enzyme-linked immunosorbent assay (ELISA) at 1, 3 days and 5 days. Meanwhile, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG) and lipoprotein A were detected. The differences of each index between sepsis group (28-day death group and survival group) and healthy control group were compared. Meanwhile, the indexes of patients with different severity and 28-day prognosis in sepsis group were compared. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of PCSK9 and blood lipid for the prognosis of sepsis. Multivariate Logistic regression was used to analyze the influencing factors for the prognosis of sepsis, and the Kaplan-Meier survival curve at 28th day was drawn.Results:There were 50 patients in sepsis group (including 19 patients with sepsis, 31 patients with septic shock) and 27 patients in healthy control group. In the sepsis group, 19 patients died and 31 patients survived within 28 days. The serum PCSK9 in the sepsis group was significantly higher than that in the healthy control group [μg/L: 223.09 (198.47, 250.82) vs. 188.00 (165.27, 214.90), P < 0.01], and HDL-C, LDL-C, TC and lipoprotein A were significantly lower than those in the healthy control group [HDL-C (mmol/L): 0.82±0.35 vs. 1.45±0.24, LDL-C (mmol/L): 1.53 (1.14, 2.47) vs. 2.89 (2.55, 3.19), TC (mmol/L): 2.03 (1.39, 2.84) vs. 4.24 (3.90, 4.71), lipoprotein A (g/L): 8.80 (5.66, 17.56) vs. 27.03 (14.79, 27.03), all P < 0.01]. PCSK9 in the sepsis death group was higher than that in the survival group [μg/L: 249.58 (214.90, 315.77) vs. 207.01 (181.50, 244.95), P < 0.01], and the HDL-C, LDL-C and TC were lower than those in the survival group [HDL-C (mmol/L): 0.64±0.35 vs. 0.93±0.30, LDL-C (mmol/L): 1.32±0.64 vs. 2.08±0.94, TC (mmol/L): 1.39 (1.01, 2.23) vs. 2.69 (1.72, 3.81), all P < 0.01]. With the progression of the disease, the PCSK9 in the sepsis death group and the survival group was significantly lower than that within 1 day of diagnosis (all P < 0.05). ROC curve analysis showed that PCSK9 had higher predictive value of 28-day death than HDL-C, LDL-C, TC [area under ROC curve (AUC) and 95% confidence interval (95% CI): 0.748 (0.611-0.885) vs. 0.710 (0.552-0.868), 0.721 (0.575-0.867), 0.702 (0.550-0.854)]. Multivariate Logistic regression analysis showed that PCSK9 was an independent risk factor affecting the 28-day prognosis of sepsis (β value was 1.014, P = 0.020). Kaplan-Meier survival curve analysis showed that when PCSK9 ≥ 208.97 μg/L, with the increase of PCSK9, the 28-day survival rate of sepsis patients decreased significantly. Conclusions:PCSK9, HDL-C, LDL-C and TC can all predict the 28-day prognosis of patients with sepsis. The prognostic value of PCSK9 is the highest. PCSK9 is an independent risk factor affecting the prognosis of sepsis. In the early stage of the disease, PCSK9 may have a good predictive value for the prognosis of sepsis. When PCSK9 ≥ 208.97 μg/L, the 28-day survival rate decreased significantly.

Objective @#To examine the effect of moderate aerobic exercise on the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) in patients with hypercholesterolemia, so as to provide insights into ASCVD prevention.@*Methods @#The patients with hypercholesterolemia admitted to the Affiliated Hospital of Hebei University from September 2019 to September 2020 were recruited and randomly assigned into the intervention group and the control group using a random number table. Participants in both groups received routine lipid-lowering therapy and health education, and participants in the intervention group were given additional interventions of moderate aerobic exercise. Serum lipid levels were measured before and after 12 weeks of interventions. The 10-year risk of developing ASCVD was evaluated in both groups following interventions.@*Results @#There were 50 participants with hypercholesterolemia in each of the intervention and control groups. The mean age was ( 38.80±1.42 ) years in the intervention group and ( 37.14±1.23 ) years in the control group, and males were accounted for 46.00% and 40.00%, respectively. The increase in high-density lipoprotein cholesterol ( HDL-C ), the reduction in total cholesterol ( TC ), triglyceride ( TG ), low-density lipoprotein cholesterol ( LDL-C ) and the 10-year risk of ASCVD were all significantly greater in the intervention group than those in the control group before and after the interventions ( P<0.05 ).@*Conclusion @#Moderate aerobic exercise may reduce the 10-year risk of ASCVD through regulating blood lipid levels.

The relationship between the lipid profiles and inflammation in patients with sepsis / 中华危重病急救医学

Objective:To explore the relationship between the changes in the lipid profiles and the intensity of inflammatory response and disease severity in patients with sepsis, in order to find a biomarker that can quickly evaluate the condition and prognosis of sepsis.Methods:A retrospective analysis was performed on 449 patients with sepsis admitted to department of critical care medicine of the First Affiliated Hospital of Zhengzhou University from October 2019 to May 2021, and 355 patients without sepsis hospitalized in the same period served as the control. The general demographic data, blood lipid and other clinical indicators within 24 hours after admission were collected and compared between the two groups. Bivariate correlation study was used to analyze the relationship between blood lipid levels and inflammation indicators and severity of illness in patients with sepsis. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of each blood lipid component on the 28-day mortality of patients with sepsis. According to the results of ROC curve analysis, the blood lipids were divided into two groups with different levels, and the Kaplan-Meier survival curve was used to compare the cumulative survival rates of the two groups without end-point event (the 28-day mortality was the end-point event).Results:Compared with non-septic patients, the levels of plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were significantly lower in patients with sepsis [TC (mmol/L): 2.93±1.33 vs. 4.01±1.14, HDL-C (mmol/L): 0.78±0.47 vs. 1.16±0.40, LDL-C (mmol/L): 1.53±1.00 vs. 2.71±0.98, all P < 0.05]. In patients with sepsis, plasma cholesterol levels were correlated with the degree of inflammation and severity of the disease to varying degrees, but the HDL-C had the strongest correlation with interleukin-6 (IL-6; r = -0.551, P = 0.000), procalcitonin (PCT, r = -0.598, P = 0.000), sequential organ failure assessment (SOFA; r = -0.285, P = 0.000). The ROC curve analysis showed that among all blood lipid components, HDL-C had the highest predictive value for 28-day mortality of sepsis patients, and the area under the ROC curve (AUC) was 0.718, when the best cut-off value was 0.69 mmol/L, the sensitivity and specificity were 67.3% and 65.2% respectively, and the positive predictive value and negative predictive value were 60.6% and 71.5% respectively. According to Kaplan-Meier survival curve analysis, the mortality of sepsis patients with HDL-C ≤ 0.69 mmol/L was significantly higher than the patients with HDL-C > 0.69 mmol/L, and the difference was statistically significant ( P < 0.000 1). In addition, the 28-day mortality [59.73% (135/226) vs. 28.70% (64/223)], the incidence of multiple organ dysfunction [41.15% (93/226) vs. 31.84% (71/223)], the probability of requiring mechanical ventilation and vasoactive drugs [mechanical ventilation: 56.64% (128/226) vs. 46.18% (103/223); vasoactive drugs: 54.42% (123/226) vs. 38.57% (86/223)], the positive rate of microbial culture [45.58% (103/226) vs. 35.43% (79/223)], and the probability of drug-resistant bacteria [19.91% (45/226) vs. 10.31% (23/223)] in the low HDL-C group of sepsis patients were all higher than the high HDL-C group, the differences were statistically significant (all P < 0.05). Conclusions:Plasma cholesterol levels, especially the HDL-C levels, can well reflect the intensity of inflammation and the severity of the disease in patients with sepsis. And the HDL-C levels can be used as a good biomarker for predicting the short-term prognosis of sepsis.

Objective:To investigate the effectiveness of early levothyroxine intervention in pregnancy complicated with hypothyroidism.Methods:A retrospective analysis was performed on 132 pregnant patients with hypothyroidism admitted to the Department of Endocrinology, Anyang People’s Hospital from Nov. 2018 to Sep. 2021. Among them, 68 cases with levothyroxine sodium early intervention were included in the intervention group, and 64 cases without intervention were included in the non-intervention group. The differences in vascular endothelial function indexes, thyroid function indexes, and blood lipid indexes before and after treatment in the intervention group were compared with those in the non-intervention group. The incidence of obstetric complications such as preeclampsia, fetal growth restriction, and adverse pregnancy outcomes of abortion and neonatal asphyxia were compared between the two groups. SPSS 21.0 software was used to process data, measurement data were subjected to t test, and enumeration data were subjected to χ 2 test. Results:After treatment, the endothelium-dependent brachial artery blood flow-mediated vasodilation index (FMD) index, nitric oxide (NO) , and endothelin-1 (ET-1) levels in the intervention group were significantly better than those in the non-intervention group [ (10.37%) ±1.54%) vs (7.25% ± 1.09%) , (60.85 ± 7.03) umol/L vs (39.11 ± 4.31) umol/L, (112.96 ± 13.58) umol/L vs (238.85 ± 26.05) umol/L]. After treatment, the serum thyroid stimulating hormone (TSH) in the intervention group was significantly lower than that in the non-intervention group [ (2.25±0.26) mU/L vs (8.79±1.60) mU/L] ( P<0.001) . After treatment, the levels of total cholesterol (TC) , triacylglycerol (TG) and low-density lipoprotein cholesterol (LDL-C) in the intervention group were significantly lower than those in the non-intervention group [ (3.52±0.91) mmol/L vs (6.51±1.31) mmol/L L, (1.30±0.31) mmol/L vs (1.44±0.36) mmol/L, (2.29±0.31) mmol/L vs (3.32±0.44) mmol/L] ( P<0.001, P=0.036, P<0.001) . The incidence of obstetric complications such as preeclampsia, fetal growth restriction, premature rupture of membranes, and abnormal amniotic fluid volume in the intervention group were significantly lower than those in the non-intervention group (5.88% vs 17.19%, 1.47% vs 9.38%, 10.29% vs. 23.44%, 2.94% vs 12.50%) ( P=0.041, 0.043, 0.043, 0.038) ; the incidence of miscarriage, premature birth, neonatal asphyxia, cesarean section and other adverse pregnancy outcomes in the intervention group were significantly lower than those in the non-intervention group (1.47% vs 9.38%, 4.69% vs 15.36%, 2.94% vs 10.94%, 57.35% vs 75.00%) ( P=0.043, 0.031, 0.038, 0.033) . Conclusion:Early intervention with levothyroxine in pregnancy complicated with hypothyroidism is beneficial to improve thyroid function, reduce blood lipid level, protect vascular endothelial function, reduce related obstetric complications, and reduce the incidence of adverse pregnancy outcomes for mothers and infants.

MethodSeventy New Zealand rabbits were randomly divided into normal group （n=10） and model group （n=60）. The blood stasis syndrome was modeled by the method of starvation+high-fat feed+adrenaline. After the models were successfully established， they were randomly divided into Xuefu Zhuyutang（3.55 g·kg-1·d-1） group， Danshenyin（1.962 g·kg-1·d-1） group， Shixiaosan（0.56 g·kg-1·d-1） group， Huoluo Xiaolingdan（2.80 g·kg-1·d-1） group， and Taohong Siwutang（2.66 g·kg-1·d-1） group， and were given corresponding compound prescriptions by gavage. The normal group and model group were given the same dose of distilled water. After the treatment of 30 consecutive days， blood was taken from the abdominal aorta to detect the content of total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol（LDL-C） and apolipoprotein A1 （ApoA1）. Hematoxylin-eosin（HE） staining was used to observe the changes in liver tissue. Real-time polymerase chain reaction （Real-time PCR） and Western blot were used to detect the mRNA and protein expression of ABCA1 and PPARγ in liver tissue， respectively. ResultCompared with the conditions in the normal group， increased mRNA and protein levels of HDL-C， LDL-C， TG， TC， and PPARγ （P<0.01）， decreased ApoA1 level （P<0.05） and decreased mRNA and protein levels of ABCA1 （P<0.01） were found in the model group. Compared with the conditions in the model group， the HDL-C level in the five Huoxue Huayu prescriptions was lowered （P<0.05）， and lowered TG level in Xuefu Zhuyutang group and Shixiaosan group （P<0.05）， decreased LDL-C and TC levels in Shixiaosan group （P<0.05）， and increased ApoA1 level in the Huoluo Xiaolingdan group （P<0.01） and Taohong Siwutang group （P<0.05） were observed. Furthermore， the mRNA and protein levels of ABCA1 in Xuefu Zhuyutang group， Shixiaosan group， Huoluo Xiaolingdan group and Taohong Siwutang group were elevated （P<0.05， P<0.01）， and the elevated levels were higher than that of Danshenyin group （P<0.05）. The mRNA level of PPARγ in the five Huoxue Huayu prescriptions was reduced （P<0.01）， and its protein level was also decreased in Xuefu Zhuyutang group， Shixiaosan group， Huoluo Xiaolingdan group and Taohong Siwutang group （P<0.01）. ConclusionThe five Huoxue Huayu prescriptions had a certain therapeutic effect on dyslipidemia，which might be achieved by up-regulating the expression of ApoA1 and ABCA1 to promote the production of HDL-C and strengthen the excretion of dysfunctional HDL-C. And Xuefu Zhuyutang had the optimal effect in lowering lipid.

Interaction between Abnormal Prepregnancy Body Mass Index and Hyperlipidemia during Pregnancy on the Risk of Gestational Diabetes Mellitus / 中国医学科学院学报

Objective To explore the interaction between abnormal prepregnancy body mass index(pBMI)and high blood lipid level during pregnancy on the risk of gestational diabetes mellitus(GDM). Methods A total of 235 patients with GDM and no blood lipid-related diseases before pregnancy were selected from Hangzhou Women's Hospital during March 2017 to July 2018 as the GDM group.At a ratio of 1∶3,a total of 705 individual age-matched pregnant women with normal glucose metabolism during prenatal examination from the same hospital were selected as the control group.The generalized multifactor dimension reduction(GMDR)method was employed to characterize the possible interaction between pBMI-blood lipid and GDM.The cross-validation consistency,equilibrium test accuracy,and P value were calculated to evaluate the interaction of each model. Results GMDR model analysis showed that the second-order model including pBMI and gestational blood lipid level had the best performance(P=0.001),with the cross-validation consistency of 10/10 and the equilibrium test accuracy of 64.48%,suggesting that there was a potential interaction between pBMI and gestational high blood lipid level.After adjustment of confounding factors,the model demonstrated that overweight/obesity patients with high triglyceride(TG) level had the highest risk of developing GDM(OR=14.349,95%CI=6.449-31.924,P<0.001).Stratified analysis showed that overweight/obesity patients under high TG level group had a higher risk of developing GDM than normal weight individuals(OR=2.243,95%CI=1.173-4.290,P=0.015). Conclusions Abnormal pBMI and high blood lipid level during pregnancy are the risk factors of GDM and have an interaction between each other.Overweight/obese pregnant women with high TG levels are more likely to develop GDM.

Objective@#To investigate the prevalence of dyslipidemia among adult professional athletes in Guangdong Province, so as to provide insights into dyslipidemia screening and health management among professional athletes.@*Methods@#In 2019, active athletes at ages of 18 to 30 years were recruited from 12 provincial sports teams in Guangdong Province using a cluster sampling method. A self-designed questionnaire survey was conducted to collect gender, age and sport items, and the levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were detected. The non-HDL-C level was calculated, and the gender- and sport item-specific prevalence of dyslipidemia was estimated.@*Results@#Totally 460 athletes were investigated, including 245 males (53.26%) and 215 females (46.74%), with a mean age of (21.91±2.77) years. The overall detection of dyslipidemia was 25.87%, and the detection rates of high TG, high TC, high LDL-C, low-HDL-C and high non-HDL-C were 20.22%, 5.87%, 13.04%, 3.26% and 9.57%, respectively. The detection rates of high TG (9.39% vs. 1.86%; χ2=11.743, P<0.05), low HDL-C (5.31% vs. 0.93%; χ2=6.951, P<0.05) and high non-HDL-C (12.24% vs. 6.51%; χ2=4.351, P<0.05) were significantly greater in men than in women, and the detection of high TC was lower in men than in women (17.96% vs. 22.79%; χ2=8.627, P<0.05). There was a significant difference in the detection of dyslipidemia among athletes engaging in different sport items (χ2=47.552, P<0.05), and a high detection rate of dyslipidemia was seen in baseball athletes (34.29%), softball athletes (37.04%), shooting/archery athletes (52.73%).@*Conclusion@#The prevalence of dyslipidemia was 25.87% among adult professional athletes in Guangdong Province, and high TC in combination with high LDL-C were the predominant type of dyslipidemia. The management of blood lipids should be given a high priority to male athletes and baseball, softball and shooting/archery athletes.

Impact of Toxoplasma gondii human infections on blood lipid levels / 中国血吸虫病防治杂志

Objective To evaluate the impact of Toxoplasma gondii human infections on blood lipid levels. Methods A total of 1 000 healthy volunteers that were randomly sampled from a tertiary hospital during the period from December 2017 through December 2019 were enrolled, and assigned into the infection group and the control group according to the detection of serum anti-T. gondii antibody using enzyme-linked immunosorbent assay (ELISA). The serum levels of total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglyceride (TG) were detected and compared between the two groups. Results The seroprevalence of anti-T. gondii antibody was 8.40% in the study subjects, and there were no significant differences between the infection and control groups in terms of gender (χ2 = 1.29, P > 0.05) or age (χ2 = 1.41, P > 0.05). The mean serum LDL (t = 3.89, P < 0.05) and TC levels (t = 3.81, P < 0.05) were significantly higher in the infection group than in the control group, while no significant differences were seen between the two groups in terms of mean serum TG (t = 0.97, P > 0.05) or HDL levels (t = 0.75, P > 0.05). In addition, the proportions of abnormal LDL (χ2 = 9.69, P < 0.01) and TC levels (χ2 = 10.39, P < 0.01) were significantly greater in the infection group than in the control group, while no significant differences were found in the proportion of abnormal TG (χ2 = 0.02, P > 0.05) or HDL level (χ2 = 0.11, P > 0.05) between the two groups. Conclusion T. gondii human infections affect blood lipid levels, and the individuals sero-positive for anti-T. gondii antibody have higher mean serum LDL and TC, as well as higher proportions of abnormal TC and LDL than sero-negative individuals.

Evaluation on the application of light scattering method to detect hemoglobin in lipoblood samples / 中华检验医学杂志

Objective:To evaluate the ability of light dispersive colorimetry to detect hemoglobin (Hb) in lipid blood samples and its feasibility as an alternative to plasmapheresis commonly used in the laboratory.Methods:Routine blood samples of 276 inpatients in Fujian Provincial Hospital from July 2020 to July 2021 were collected. Routine blood samples of 276 inpatients were collected. There were 169 males and 107 females, aged from 16 to 97 years. 183 non-lipid blood samples and 93 lipid blood samples were collected.(1) One case each of low, medium and high Hb value in non-lipid blood and lipid blood samples were collected, and the precision and the linearity of light scattering method was detected.(2)Non-lipid blood samples divided into Hb low-value group, median-value group and high-value group, which were measured by light scattering method and colorimetric method to compare Hb values. (3)Non-lipid blood samples were divided into Hb low-value group, median-value group and high-value group. Plasma exchange was carried out with different concentrations of fat emulsion. The bias and linearity of Hbc2 and Hbc1, Hbo2 and Hbc1 were analyzed by MedCalc19.1 software. The Hbc2 and Hbc1 bias ( CV%) and Hbo2 and Hbc1 bias ( CV%) were calculated. T test was used to analyze the influence of different concentrations of triglyceride on Hb bias.(4)Blood samples were divided into Hb low-value group, median-group and high-value group. The Hb of light scattering method was compared with the colorimetric method after plasma exchange. Results:(1)The intrabatch precision of light scattering method for non-lipid blood and lipid blood specimens was within the allowable range ( CV<1.5%), and the good linearity ( R2=1.000).(2)The bias of Hb measured by light scattering method and colorimetric method in the three groups was below 3.5%(-0.58±2.34,0.16±1.52,1.15±1.56), within the allowable total error range. The two methods have the equivalence and good linear relationship ( r=0.999).(3)The concentrations of Hbo2 in the low (except 4.1 mmol/L), medium and high Hbo2 groups were equivalent to those in the non-lipid blood colorimetry (Hbc1), and the two methods were well correlated. The results of light scattering method have nothing to do with the concentration of lipid blood.(4)There was no significant difference of the Hb between the light scattering method and plasma exchange method in three groups ( P>0.05), Both of them have equivalence and good correlation ( R2=0.968,0.948,0.870). Conclusion:Light scattering method can effectively reduce the effect of lipid blood on hemoglobin determination, and can replace the traditional plasma exchange method, which has high clinical application value.

Objective:To analyze the correlation between simple thyroid nodule and blood lipid and glucose metabolism and iodine nutrition level.Methods:A cross-sectional study was conducted by collecting data of the population undergoing epidemiological investigation in Jinshan District, Shanghai from July to December 2015, to calculate the prevalence of thyroid nodules and analyze relevant functional indicators.Results:Simple thyroid nodules were detected in 603 subjects, with a prevalence of 22.6% (603/2 669). There were 358 female patients with simple thyroid nodules, with a prevalence rate of 26.9%, and 245 male patients with simple thyroid nodules, with a prevalence rate of 18.3%. The prevalence of simple thyroid nodule in female was higher than that in male, and the difference was statistically significant (χ 2=27.686, P<0.001). In addition, the prevalence of simple thyroid nodules increased with age (13.1% (92/704) and 20.2% (104/514) and 25.1% (145/578) and 24.4% (107/439) and 36.3% (98/270) and 34.8% (57/164), χ 2=83.872,P<0.001). In the ≤30 years group (8.0% (30/704) vs. 18.8% (62/331), χ 2=35.716, P<0.001), >30 to ≤40 years old group (14.1% (37/263) vs. 26.7% (67/251), χ 2=12.683, P<0.001), >60 to ≤70 years old group (26.2% (33/126) vs. 45.1% (65/144), χ 2=10.435, P<0.001), and the 70-year-old group (24.4% (21/86) vs. 46.2% (36/78), χ 2=8.521, P<0.001). The prevalence of simple thyroid nodules in males was lower than that in females. In the simple positive thyroid nodule group, Fasting blood glucose (5.12 (4.80, 5.69) and 5.02 (4.72, 5.48)), total cholesterol (1.24 (0.85, 1.86) and 1.13 (0.77, 1.76)), triglyceride (4.77 (4.09, 5.48) and 4.49 (3.92, 5.16)), low density lipoprotein((2.79 (2.26, 3.36) and 2.63 (2.19, 3.16)), and high density lipoprotein cholesterol (1.41 (1.18, 1.66) and 1.35 (1.13, 1.61)) were higher than those in the negative group ( U values were 554 818, 578 468, 535 622, 556 067 and 567 960, respectively, all P<0.01). The BMI index grade distribution of thyroid nodule positive group was higher than that of negative group, and the difference was statistically significant (3.7% (77/2 066), 50.1% (1 034/2 066), 32.4% (669/2 066), 13.8% (286/2 066), 3.2% (19/603), 43.6% (263/603), 38.1% (230/603), 15.1% (91/603), χ2=9.5201, P=0.023). The prevalence of simple thyroid nodules was significantly lower in the iodized salt group than in the non-iodized salt group (20.7% (436/2 102) vs. 29.5% (167/567), χ 2=19.376, P<0.001). The urinary iodine level in the positive thyroid nodule group was significantly lower than that in the negative group (148.4(100.2, 213.7) vs. 169.5(115.4, 241.75), U=545 129.5, P<0.001). After Logistic regression screening, age ( OR=1.57, 95% CI: 1.292-1.908, P<0.001), gender ( OR=1.278, 95% CI: 1.193-1.368, P<0.001), BMI grade ( OR=1.166, 95% CI: 1.022-1.330, P=0.022), total cholesterol ( OR=1.105, 95% CI: 1.005-1.214, P=0.040), iodized salt ( OR=0.689, 95% CI: 0.556-0.854, P=0.001) were independent influencing factors of thyroid nodule. Conclusion:The prevalence of simple thyroid nodules in Shanghai is relatively low. Age, sex, BMI level, total cholesterol and iodized salt are independent factors causing thyroid nodules. In addition, blood glucose level may also be related to the prevalence of thyroid nodules.

Clinical study on non-fasting blood lipids in patients with type 2 diabetes / 中华内分泌外科杂志

Objective:To study the feasibility of non-fasting blood lipid detection in patients with type 2 diabetes mellitus (T2DM) .Methods:A total of 426 diabetic patients hospitalized in the Second Hospital of Tianjin Medical University from Oct. 2018 to Apr. 2019 were selected to collect blood samples from the fasting and non-fasting state of the patients respectively. The levels of plasma three acylglycerol (TG) , total cholesterol (TC) , high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were measured at the same time, and self-control method was used. The results of two tests were compared with the wilcoxon signed-rank test.Results:Compared with the fasting results, non-fasting TG increased by 0.25 mmol/L (11.2%) , with statistical significance ( P<0.05) ; TC increased by 0.17 mmol/L (4.5%) , HDL-C increased by 0.08 mmol/L (5.7%) , and LDL-C decreased by 0.05 mmol/L (5.9%) , without significant differenc ( P>0.05) . Conclusion:Except for TG, non-fasting TC, HDL-C, LDL-C has little change compared with those in fasting state, which can replace fasting blood lipid detection as a method for detecting blood lipid profile in patients with T2DM.

Objective:To study the effects of Empagliflozin on left ventricular function and the level of blood glucose and lipid in type 2 diabetes mellitus (T2DM) patients.Methods:A total of 120 patients with T2DM complicated with cardiac function impairment were selected from Chu Hsien-I Memorial Hospital, Tianjin Medical University from December 2020 to May 2021. The diabetic patients were randomly divided into the observation group (60 cases) and control group (60 cases) by random number table method. Patients in the observation group were treated with Empagliflozin, while the control group underwent original hypoglycemic treatment. After the treatment, 6 cases were eliminated and 114 cases were completed, with 57 cases in each group. The changes of echocardiographic left ventricular function related indexes such as E/ e', left atrial volume index (LAVI), tricuspid regurgitation speed, left ventricular ejection fraction (LVEF) and laboratory indexes in the two groups were observed before and after treatment. The laboratory indexes checked include fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL) and how density lipoprotein (HDL). Results:The E/ e', LAVI of the observation groups was significantly lower than that of the control group, and the differences were statistically significant (all P<0.05). There were no significant changes in tricuspid regurgitation speed, LVEF, TG, TC, LDL and HDL levels between the two groups after the treatment (all P>0.05). After the treatment, the levels of FBG and HbA1c in the two groups decreased, but there was no significant difference between the two groups (all P>0.05). Conclusions:Empagliflozin can effectively control the E/ e', LAVI of T2DM patients, and can early significant improvement of left ventricula diastolic function, which is very favorable for the patients. Along with good safety, Empagliflozin is suitable for clinical recommendation.
