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.

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.

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.

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.

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.

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.

Effect of Five Huoxue Huayu Prescriptions on Blood Lipid Metabolism， Liver Tissue and ABCA1 and PPARγ Expression in New Zealand Rabbits with Blood Stasis Syndrome / 中国实验方剂学杂志

ObjectiveTo observe the effects of five Huoxue Huayu prescriptions on blood lipid metabolism， liver tissue and adenosine triphosphate binding cassette transporter A1 （ABCA1） and peroxisome proliferator-activated receptor γ（PPARγ） expression in New Zealand rabbits with blood stasis syndrome， and to compare their differences in order to provide laboratory evidence for clinical selection of prescriptions and drugs. 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.

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.

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.

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.

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.

Impact of pre-pregnancy body mass index, weight gain and blood lipid level during pregnancy on pregnancy outcome in patients with gestational diabetes mellitus / 浙江大学学报·医学版

To explore the effects of pre-pregnancy body mass index (BMI), weight gain and blood lipid level during pregnancy on pregnancy outcome in patients with and without gestational diabetes mellitus(GDM). A total of 12 650 singleton pregnant women without history of hypertension and diabetes who were admitted at Women's Hospital, Zhejiang University School of Medicine for delivery from January 2018 to April 2019 were enrolled in the study. There were 2381 cases complicated with gestational diabetes (GDM group) and 10 269 cases without GDM (non-GDM group). The pre-pregnancy BMI and weight gain during pregnancy were documented in two groups. The factors related to perinatal outcome were analyzed. In both GDM and non-GDM pregnant women, pre-pregnancy overweight and excessive weight gain during pregnancy were independent factors of large for gestational age infant (LGA), small for gestational age infant (SGA) and first cesarean section (<0.01 or <0.05). Excessive weight gain during pregnancy was also an independent risk factor of preeclampsia (<0.05). Triglyceride levels in the second trimester were independently associated with multiple adverse pregnancy outcomes, such as LGA, preeclampsia, initial cesarean delivery, premature delivery. Controlling excessive or insufficient weight gain during pregnancy can significantly reduce the incidence of LGA and SGA. And controlling BMI before pregnancy can effectively reduce the incidence of LGA, preeclampsia and the first cesarean section. For non-GDM pregnant women, abnormal blood lipid levels in the second trimester may be closely related to multiple adverse pregnancy outcomes, and active dietary guidance or treatment is also required.

Impact of family history of diabetes on blood glucose, lipid levels and perinatal outcomes in pregnant women with gestational diabetes mellitus / 浙江大学学报·医学版

To investigate the impact of family history of diabetes (FHD) on blood glucose, lipid levels and perinatal outcomes in pregnant women with gestational diabetes mellitus (GDM). A total of 1265 GDM women who gave childbirth in Women's Hospital, Zhejiang University School of Medicine during January to December 2019 were enrolled in the study, including 253 women with FHD and 1012 women without FHD. The -test or test were used to compare the blood lipid, blood glucose levels and perinatal outcomes including large for gestational age infant, small for gestational age infant, macrosomia, cesarean delivery, preeclampsia, preterm labor, postpartum hemorrhage, fetal distress. The correlation between FHD and perinatal outcomes were estimated by Logistic regression analysis. The high density lipoprotein level at third-trimester was significantly lower in GDM women with FHD (<0.05); and the women with FHD also had higher fasting blood glucose oral glucose tolerance test (OGTT)1 h, OGTT 2 h and glycosylated hemoglobin level (all <0.01). In GDM women, FHD was an independent risk factor for preeclampsia (=3.27, 95%: 1.39-7.68). GDM women with FHD have lower high density lipoprotein and higher glucose levels. FHD is an independent risk factor for preeclampsia in GDM women.

Mechanism of Astragali Radix-Coptis Rhizoma pair in treating type 2 diabetes mellitus based on network pharmacology / 中国中药杂志

This study aims to explore the main mechanism of Astragali Radix-Coptis Rhizoma pair(hereinafter referred to as the pair) in the treatment of type 2 diabetes mellitus(T2 DM) based on network pharmacology and animal experiment. The main Chinese medicine compound prescriptions for T2 DM were retrieved from CNKI database and the medicinals with high frequency among these prescriptions were screened. The active components in the above medicinals were searched from TCMSP, TCMID, and previous research, targets of the components from SwissTargetPrediction and SEA, and targets for the treatment of T2 DM from DISGENET, TTD, and DrugBank. Thereby, the medicinal-component-disease-target network was constructed with Cytoscape. The targets were input in String database to yield the related proteins and the protein-protein interaction(PPI) network was constructed by Cytoscape. The biological functions of proteins in the PPI network were analyzed by Cluego. Then, high-fat high-sugar diet and 30 mg·kg~(-1) streptozotocin(STZ, intraperitoneal injection, once) were employed to induce T2 DM in rats and the T2 DM rats were classified into the control group, model group, positive drug(metformin) group, and pair group. After one month of administration, the changes of blood glucose and blood lipids [triglyceride(TG), cholesterol(CHO), low density lipoprotein(LDL), high density lipoprotein(HDL)] were detected with biochemical methods and pathological changes of islet and collagen deposition in pancreatic tissue by HE staining and Masson staining, respectively. The result showed that pair can be used for T2 DM treatment. ras-related C3 botulinum toxin substrate 1(RAC1), paraoxonase 1(PON1), beta-galactoside alpha 2,6-sialyltransferase 1(ST6 GAL1), insulin receptor(INSR), sex hormone-binding globulin(SHBG), ileal sodium/bile acid cotransporter(SLC10 A2), endothelin-1 receptor A(EDNRA), peroxisome proliferator-activated receptor A(PPARA), endothelin receptor B(EDNRB), and 5-hydroxytryptamine receptor 2 A(HTR2 A) were the targets of the pair for the treatment of T2 DM. The main biological functions of the pair were regulating the metabolism of blood glucose and li-pids and protecting the cardiovascular system. The fasting blood glucose, and serum TG, CHO, and LDL were higher(P<0.01) and the HDL was lower(P<0.05) in the model group than in the control group on the 7 th, 14 th, and 28 th days. The fas-ting blood glucose and the serum TG, CHO, and LDL decreased(P<0.05) and the serum HDL increased(P<0.05) in the metformin group and the pair group as compared with those in the model group on the 14 th and 28 th days. There were no significant differences in blood glucose, TG, CHO, LDL, and HDL between the metformin group and the pair group. Rats in the model group demonstrated damaged structures of islets and pancreas, obviously increased deposition of collagen in islets and pancreas, and blurred cell boundaries. Metformin and the pair significantly alleviated the damaged structures and collagen deposition. The pair can effectively regulate the disorders of blood glucose and lipid metabolism in T2 DM and protect the structure and functions of pancreas and islets by controlling cardiovascular system, which is worthy of clinical application and can be used for drug development.

Analysis of the relationship between BMI and blood lipids, blood glucose and blood uric acid in 3 860 employees in a university / 公共卫生与预防医学

Objective To investigate the relationship between BMI and blood lipids, blood glucose and blood uric acid. Methods A total of 3 860 employees from a university who underwent physical examination in 2018 were selected and divided into obesity group, fat group, normal group and lean group according to their body mass index. The levels of blood lipids, fasting blood glucose and blood uric acid among different groups were analyzed and compared. Results There were a total of 1,889 people in the obesity group and fat group, accounting for 48.94% of the total. The weight difference among the different groups was statistically significant (P＜0.05), while there was no statistical significance in age difference among different groups. The height in the obese group and fat group was significantly different compared with the normal group. There were significant differences in the levels of triglyceride (TG), high-density lipoprotein (HDL-C) and blood uric acid (UA) in the different groups (P<0.05). The fasting blood glucose level (GLU) in both the obesity group and fat group was significantly different compared with the normal group (P<0.05). With the increase in body weight index, the proportion of high blood fat, fatty liver, hyperglycemia and high blood uric acid all increased significantly as compared with the normal group or the lean group, and the differences were statistically significant (P<0.05). The proportion of fatty liver and hyperuricemia in the male was higher than that in the female. Conclusion The risk of high blood fat, fatty liver, hyperglycemia and hyperuricemia in college faculty and staff was significantly increased with the increase of BMI. It is suggested that the college employees should have a balanced diet, increase exercise, and control BMI within a reasonable range.

Research progress on ATP citrate lyase (ACLY) inhibitors for decreasing blood lipids / 药学学报

Cardiovascular disease is a principal cause of morbidity and death in the world. Although drug therapy has made great progress in the past few decades, there are still many deficiencies in the prevention and treatment of cardiovascular disease. Dyslipidemia is still a common risk feature and is not sufficiently controlled. A growing body of evidence suggests that the occurrence and development of cardiovascular disease is associated with many associated risk factors, such as higher low-density lipoprotein levels, lower high-density lipoprotein levels and high triglyceride levels. A number of clinical trials in patients with dyslipidemia have shown that actively decreasing low density lipoprotein cholesterol can significantly decrease cardiovascular events. ATP citrate lyase (ACLY) is a cytoplasmic homo-tetrameric enzyme. In the presence of adenosine triphosphate (ATP), ACLY catalyzes the conversion of citric acid and coenzyme A to acetyl-CoA and oxalyl acetate. ACLY is the main enzyme for the production of cytoplasmic acetyl-CoA, and cytoplasmic acetyl-CoA is the precursor required for de novo synthesis of cholesterol and fatty acids. Therefore, it is possible to reduce the production of acetyl-CoA and reduce the levels of cholesterol and triglycerides by inhibiting ACLY. ACLY can be used as a molecular target for reducing blood lipids, and there are an increasing number of studies on ACLY inhibitors. In this paper, the structure and mechanism of ACLY and its relationship with lipid metabolism are briefly introduced, and we review some current ACLY inhibitors.
