Combination of purple sweet potato (Ipomoea batatas L.) leaf extract with metformin on blood glucose and total cholesterol levels of albino rats induced by high-fat diet and streptozotocin

Background: Diabetes mellitus is a metabolic disease characterized by hyperglycemia due to impaired insulin secretion, often accompanied by hypercholesterolemia. Metformin is a first-line antihyperglycemic drug that is often combined with other antihyperglycemic drugs. Purple sweet potato leaves have been widely studied to reduce glucose and cholesterol levels. Methods: This study was an experimental study using rats induced with a high-fat diet and streptozotocin, which were divided into 8 treatment groups, namely groups given CMC Na 0.5%, Metformin 45 mg/kg BW, Purple Sweet Potato Leaf Extract (SPLE) 200 mg/kg BW, SPLE 400 mg/kg BW, SPLE 800 mg/kg BW, SPLE 200 mg/kg BW with metformin 45 mg/kg BW, SPLE 400 mg/kg BW with metformin 45 mg/kg BW, and SPLE 800 mg/kg BW with metformin 45 mg/kg BW. Results: After treatment for 28 days with SPLE doses of 200 mg, 400 mg, and 800 mg/kg BW, both single doses and combinations with metformin showed a decrease in fasting blood glucose levels and total cholesterol, which were statistically significantly different (p<0.05) between treatment groups using the one-way ANOVA. The combination of SPLE 800 mg/kg BW with metformin normalized blood glucose levels of 93.50±4.93 mg/dl. Conclusion: The combination of purple sweet potato leaf extract with metformin is more effective in reducing blood glucose and total cholesterol levels compared to the single administration of metformin and SPLE.

Total cholesterol and triglycerides status in autistic spectrum disorder children: a case-control study on Bangladeshi children

Background: Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by challenges in social interaction, communication, and repetitive behaviors. The association between lipid profiles, particularly total cholesterol and triglycerides, and ASD in children is a growing focus in pediatric health research. This study aimed to assess the total cholesterol and triglycerides status in autistic spectrum disorder children. Methods: This cross-sectional study was conducted in the department of physiology, Bangabandhu Sheikh Mujib Medical University, Dhaka from March 2014 to January 2015 with 100 male children, half in a healthy control group (group A) and the other half diagnosed with autism spectrum disorder (group B). Results: In this study, no significant correlation was found between the groups for age (p=0.94) or BMI (p=0.29). The mean (盨E) serum total cholesterol levels were 146�70 mg/dl in group A and 145.00�77 mg/dl in group B, showing no significant difference between the two groups (p=0.885). But, the mean (盨E) serum triglyceride levels were 86.14�28 mg/dl in group A and 107.74�91 mg/dl in group B, with significantly higher levels compared to group A (p<0.01). Conclusions: Although there is no significant difference in serum total cholesterol levels between healthy children and those with autistic spectrum disorder, there is a significant difference in serum triglyceride levels. Therefore, further studies are needed to provide a clearer understanding of the lipid profile comparison.

Association between the risk of increase in total cholesterol and the risk of cholelithiasis： A bidirectional Mendelian randomization study / 临床肝胆病杂志

ObjectiveTo investigate the association between the risk of increase in total cholesterol （TC） and the risk of cholelithiasis by using bidirectional Mendelian randomization （MR）. MethodsThe open gwas public database was used to obtain the single nucleotide polymorphism data associated with TC and cholelithiasis， and a secondary data analysis was performed for all summary data of genome-wide association studies. The genetic loci closely associated with TC or cholelithiasis were selected as exposure or outcome variables， and the bidirectional MR analysis was performed using the methods such as Egger regression， Weighted median， IVW random effects model， and IVW fixed effects model， with odds ratio （OR） values for evaluating the causal relationship between TC and cholelithiasis. ResultsWith TC as the exposure and cholelithiasis as the outcome， TC-cholelithiasis had an overall OR value of 0.91 （95% confidence interval ［CI］： 0.85‍ ‍—‍ ‍0.97） before elimination of heterogeneity and 0.93 （95%CI： 0.89‍ ‍—‍ ‍0.97） after elimination of heterogeneity. With cholelithiasis as the exposure and TC as the outcome， TC-cholelithiasis had an overall OR value of 0.20 （95%CI： 0.06‍ ‍—‍ ‍0.65） before elimination of heterogeneity and 0.28 （95%CI： 0.10‍ ‍—‍ ‍0.83） after elimination of heterogeneity. There was a bidirectional causal relationship between genetically predicted TC and cholelithiasis. ConclusionThis study confirms the bidirectional causal relationship between TC and cholelithiasis. The risk of cholelithiasis decreases with the increase in alleles associated with the elevation of TC level； on the contrary， the risk of elevated TC level decreases with the increase in alleles associated with the onset of cholelithiasis.

A comparative study of serum lipid profile in preeclampsia and normotensive pregnancy in third trimester and their fetomaternal outcome

Background: Preeclampsia is a common medical complication in pregnancy in developing countries. It is one of the most common causes that lead to maternal and fetal morbidity and mortality. Incidence of preeclampsia in world is 3-5%.1 In India preeclampsia complicates 5-15% of pregnancies. As a result of these changes serial alteration in lipid profile, mainly increase in serum triglycerides, cholesterol occurs in pregnant women.Methods: After IEC clearance and taking informed written consent from the patients, present study was conducted at the Department of Obstetrics and Gynaecology in PDZH, RNT Medical College, Udaipur from December 2020 to June 2022.Results: Study result based on 100 pregnant women with pre-eclampsia (BP >140/90 mm of Hg) as cases and 100 normotensive pregnant women (BP <140/90 mm of Hg) as controls. Cases had significantly higher total cholesterol (219.21±63.13 vs. 176.24±31.33, P<.0001), significantly higher triglycerides (mg/dL) (208.35±79.32 vs. 166.41±29.6, P<.0001), significantly higher LDL (mg/dL) (133.7±39.81 vs. 103.96±18.38, P<.0001), and significantly lower HDL (mg/dL) (43.29±7.09 vs. 50.18±8.15, P<.0001) in comparison to control.Conclusions: Women with pre-eclampsia had significantly higher serum Cholesterol, LDL, TG and significantly lower HDL in comparison to healthy pregnant women. There was a significant increase in the serum Cholesterol, LDL, TG in patients from mild to severe pre-eclampsia.

Background: Thyroid diseases are among the most common endocrine disorders worldwide. Thyroid hormones play a key role in regulating the synthesis, metabolism, and mobilization of lipids. Levels of circulating lipids may alter in thyroid dysfunction. Aim and Objectives: The aim of the study was to find out the alterations of lipid levels in thyroid dysfunction. Materials and Methods: The study was designed as cross-sectional observational study and analysis of values was done by significant tests difference in means. 20 patients with hypothyroidism, 20 patients with hyperthyroidism, and 20 normal were participated in the study. Levels of total cholesterol, triglycerides, high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), LDL-C, and LDL/HDL ratio were estimated and compared. Results: In patients with hypothyroidism, there was an increase in total cholesterol, LDL-C, and triglyceride levels and decrease in HDL-C levels. In hyperthyroidism, total cholesterol, triglycerides, LDL-C, VLDL-C, and LDL/HDL ratio were found to be significantly decreased. Conclusion: Altered thyroid function can lead to significant changes in the lipid profile. Hypothyroidism is an important risk factor for heart diseases. Hence, routine screening of thyroid hormones may be of considerable help for early intervention and treatment of thyroid dysfunction-related cardiac disease.

Comparative study on efficacy and safety of atorvastatin in combination with ezetimibe and atorvastatin monotherapy among patients with dyslipidemia – A randomized and double-blind study

Background: Dyslipidemia is defined as the high-density lipoprotein and apolipoprotein A (apo A) levels <10th percentile and/or total cholesterol, triglycerides, low-density lipoprotein (LDL), apolipoprotein B, or Lipoprotein (a) levels more than the 90th percentile. Aim and Objectives: This study aimed to compare the efficacy and safety of the fixed-dose combination of Atorvastatin and Ezetimibe with Atorvastatin monotherapy among patients with dyslipidemia. Materials and Methods: The present study was a randomized, double-blinded, prospective, and parallel-group study. Ninety-two outpatients of age in between 18 and 70 years from the Department of General Medicine who attended the hospital for the treatment of dyslipidemia were selected as study participants. Among 92 patients, 12 patients did not meet the study criteria. The remaining 80 patients were divided into two treatment groups at random and under double-blind conditions (39 in Group A and 41 in Group B). Each patient in both groups was followed for a period of 4 weeks after initiation of therapy. Total cholesterol and LDL-cholesterol levels were recorded at day 1, 2 weeks, and 4 weeks of therapy. Results: In this study, by the end of the study period (4 weeks), tablet Atorvastatin + tablet Ezetimibe combination therapy showed statistical significance difference in reducing mean total cholesterol and mean serum LDL levels in dyslipidemia cases than the group receiving Atorvastatin monotherapy. Conclusion: Atorvastatin in combination with Ezetimibe was more efficacious than Atorvastatin monotherapy in reducing total blood cholesterol and serum LDL levels. Atorvastatin plus Ezetimibe is equally safer as Atorvastatin monotherapy and well tolerated with fewer adverse effects.

ABSTRACT Introduction: Dyslipidaemia is the most prevalent metabolic disorder in primary Sjögren s syndrome (PSS) and an association between low HDL cholesterol levels and disease activity has been suggested. Objectives: The purpose of this study is to describe the characteristics of the lipid profile in patients with PSS and explore the correlation between the components of the lipid profile and the activity of the disease. Materials and methods: A descriptive cross-sectional study. We reviewed the medical records of patients over 18 years of age with criteria for PSS who attended the Hospital Universitario Clínica San Rafael during the period between January 2015 to December 2019. We used R-studio software version 4.0.2 for statistical analysis. A descriptive analysis of the clinical-demographic and serological variables was carried out to evaluate the correlation between them. Results: A total of 250 medical records were reviewed, of which 35 met the inclusion criteria. The average age was 53.4 years and 88.3% were women. The median duration of disease was 42 months. The mean values for total cholesterol, HDL, LDL and triglycerides were 191 mg/dL, 42.6 mg/dL, 118.9 mg/dL and 157 mg/dL respectively. A Pearson correlation coefficient of -.43 (95% CI -.67 to -.12) p-value = .008 was found between the ESSDAI activity index and HDL cholesterol. A linear model was performed between the total ESSDAI activity index and HDL cholesterol, finding an estimated coefficient of -.17. A ROC curve was performed with an HDL cholesterol segregation point of 43.5 mg/dL with an area under the curve of .603 (95% CI .40-.80). By excluding patients with high BMI, the area under the curve improved with a segregation point of 38 mg/dL. Conclusions: Patients with low levels of HDL cholesterol showed higher rates of disease activity, with a cut-off point lower than 43 mg/dL being more marked in patients with normal body mass index.

Study of the relationship between serum lipid levels and primary open-angle glaucoma

Purpose: To determine the association between serum lipid levels and primary open?angle glaucoma (POAG). Methods: In this case?control study, 50 patients with POAG documented by clinical tests using standard ophthalmologic equipment and 50 age?matched controls were investigated. Twelve?hour fasting serum lipid profiles, including total cholesterol, serum triglycerides, low?density lipoproteins (LDLs), and high?density lipoproteins (HDLs), were compared between the cases and controls. Results: The mean age of cases and controls was 62.84 ± 9.68 and 60.12 ± 8.65, respectively (P = 0.65). High total cholesterol levels (>200 mg/dl) were found in 23 cases (46%) and 8 controls (16%); high serum triglyceride levels (>150 mg/dl) were found in 24 cases (48%) and 7 controls (14%); high LDL levels (130 mg/dl) were found in 28 cases (56%) and 9 controls (18%); and low HDL levels (<40 mg/dl) were found in 38 cases (76%) and 30 controls (60%). The mean total cholesterol levels were 205.24 ± 36.90 mg/dl in cases and 177.68 ± 22.56 mg/dl in controls (P < 0.001); the mean serum triglyceride levels were 150.42 ± 49.55 mg/dl and 130.84 ± 23.16 mg/dl, respectively (P = 0.013); and the mean LDL levels were 139.50 ± 31.03 mg/dl and 114.96 ± 17.73 mg/dl, respectively (P < 0.001). The mean cholesterol, triglyceride, and LDL levels were significantly higher in cases than in controls (P < 0.05). Conclusion: The present study shows that higher proportion of POAG patients have dyslipidemia compared to age?matched controls. Though these findings need to be replicated by others. This study opens new vistas for further studies, such as lowering dyslipidemia, lowering the intra?ocular pressure and incidence of POAG, and whether the use of statins to reduce dyslipidemia affects the progression of POAG.

Impact of yoga on lipid parameters in different age groups

Background: Cardiovascular diseases (CVDs) rise first among the causes of death occurring due to non-communicable diseases in the world. The majority of cardiovascular deaths are due to ischemic heart disease and cerebrovascular disease. Among the major risk factors, dyslipidemia is an important risk factor. Hence, the prevention of dyslipidemia results in the prevention of ischemic heart disease. Dyslipidemia can be corrected by drugs but more importantly, it can be prevented by lifestyle modification. Aim and Objectives: Our aim is to observe the impact of yoga on lipid parameters in different age groups. Materials and Methods: We included 54 subjects between the age group of 30 and 60 years for this study. They were categorized into two groups: Group I having ages between 30 and 45 years (n = 23) and Group II having ages between more than 45 years and <60 years (n = 31). The lipid parameters were measured afore of yoga training, at the end of 2 months and after 6 months of yogic practices. Statistical analysis was done using the SPSS version of 20.0. A P value of less than 0.05 is considered as statistically significant. Results: Our study revealed that yoga induces a decrease in total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very LDL cholesterol and an increase in high-density lipoprotein cholesterol in both Group I and Group II subjects which were statistically significant. Conclusion: Yoga tends to improve dyslipidemia, a major risk factor for CVDs. A yoga lifestyle can be considered a preventive measure for CVDs.

Plasma lipid levels in relation to disease severity in sickle cell anaemia in Abakaliki, Southeast Nigeria

Dyslipidaemia has been implicated in the pathophysiology of sickle cell disease (SCD) complications; hence its role requires further elucidation. Objectives: To investigate the relationship between disease severity and plasma lipid levels of patients with sickle cell anaemia. Methods: A cross-sectional study design was used for the survey. A total of 50 patients with sickle cell anaemia and 50 controls without SCD were recruited for the study. The clinical data and plasma lipid levels of lipids and haemoglobin parameters were analysed. Results: The majority of the participants were aged 18-25 years. Total plasma cholesterol and HDL-C were significantly lower in individuals with SCA compared with the controls (3.3±1.2 vs 4.2±1.2; p<0.001) and (1.3±0.5 vs 1.5±0.4; p = 0.038) respectively. Most patients with SCA had moderate disease severity (24; 48%). There was no statistically significant difference in the plasma levels of total cholesterol and HDL-C across the disease severity groups of SCA (p = 0.694 and 0.262). There was also no significant correlation between total cholesterol, HDL-C, and markers ofhaemolysis, haemoglobin F, and haemoglobin S levels. Conclusion: SCA is characterised by lower mean plasma TC and HDL than controls. However, no relationship was found between TC, HDL levels and SCD disease severity, markers of haemolysis, HbF and HbS levels. Further studies are required to ascertain the implications of plasma lipid levels in SCD

Association between non-high density lipoprotein-cholesterol fractions and presence of allostatic load among industrial workers

Objectives: Non-high density lipoprotein-cholesterol (non-HDL-C) fraction is the total cholesterol (TC) minus HDL-C. It is not a routinely reported component of lipid profile and is used in lipoprotein lowering therapy and prediction of coronary artery disease, target organ damage and atherosclerosis. Allostatic load (AL) is an imbalance between repetitive chronic exposure to stress and adaptive response. The present study investigates the association between non-HDL-C and its fractions (non-HDL-C/HDL-C, non-HDL-C/TC, non-HDL-C/ triglyceride [TG] and non-HDL-C/low-density lipoprotein-cholesterol [LDL-C]) and the presence of AL to determine, which fractions of non-HDL-C predict the diagnostic accuracy and optimal cut points. Materials and Methods: The study design is cross-sectional and data were collected from 169 male industrial workers. AL was measured using neuroendocrine (cortisol and dehydroepiandrosterone sulphate), cardiovascular (systolic blood pressure, diastolic blood pressure and heart rate), metabolic (TC, TG, HDL-C and LDL-C) and anthropometric (waist-hip ratio and body mass index) factors. The fractions of non-HDL-C/HDL-C, nonHDL-C/TC, non-HDL-C/TG and non-HDL-C/LDL-C were calculated using non-HDL-C, HDL-C, TC, TG and LDL-C values. Results: About 43.2% and 56.8% of workers had low and high AL, respectively. The non-HDL-C and its fractions such as non-HDL-C/HDL-C, non-HDL-C/TC and non-HDL-C/LDL-C were significantly increased in the high AL group. Stepwise regression analysis was used to examine the association between non-HDL-C fractions and AL. The fractions of non-HDL-C (? = 0.785, P = 0.001), non-HDL-C/TC (? = ?0.336, P = 0.001) and nonHDL-C/LDL-C (? = 0.295, P = 0.001) influenced AL by 38.6%. The AUC with 95% CI in the high AL group was as follows: non-HDL-C 0.766 (0.696–0.837, P = 0.001); non-HDL-C/HDL-C 0.638 (0.555–0.721, P = 0.002); nonHDL-C/TC 0.635 (0.552–0.712, P = 0.003) and non-HDL-C/LDL-C 0.520 (0.433–0.607, P = 0.657). Non-HDL-C and its fractions were more precisely predicted in the high AL category of workers than in the low AL category. Non-HDL-C predicted the most precisely, followed by non-HDL-C/HDL-C, non-HDL-C/TC, non-HDL-C/ LDL-C and non-HDL-C/TG. Conclusion: According to the present study, non-HDL-C and its fractions such as non-HDL-C/HDL-C, nonHDL-C/TC and non-HDL-C/LDL-C should be considered regular lipid profiles and could be used as biomarkers to reduce the risk of AL.

ALDH1A3 + INS + cells in non-diabetic subjects and risk for type 2 diabetes: Analysis of cross-sectional data / 中华内分泌代谢杂志

Objective:To investigate the correlations of β cell dedifferentiation in non-diabetic subjects with risk factors for type 2 diabetes mellitus(T2DM).Methods:Immunofluorescence staining with insulin and β cell dedifferentiated marker ALDH1A3 was used to evaluate the β cell dedifferentiation levels in 38 non-diabetic and 23 T2DM. Correlation analyses were performed between β cell dedifferentiation levels and available clinical parameters including age, body mass index, HbA 1C level, triglycerides, and cholesterol levels in non-diabetic subjects. Results:β cell dedifferentiation level defined by the positive expression of ALDH1A3 in β cells(ALDH1A3 + INS + cell proportion) was significantly elevated in T2DM subjects( P<0.001). In PreD subjects, ALDH1A3 + INS + cells proportion were decreased( P=0.050) and negatively correlated with HbA 1C( r=-0.44, P=0.006), but not with age and body mass index. The analysis of correlation with lipidemic parameters showed that ALDH1A3 + INS + cells proportion was positively correlated with plasma total cholesterol level( r=0.39, P=0.045), but not plasma total triglyceride. Conclusion:ALDH1A3 + INS + cells were found to be decreased in prediabetes, suggesting that there may be enhanced β-cell identity in prediabetes to compensate for insulin secretion requirements; ALDH1A3 + INS + cells were elevated in people with high plasma total cholesterol levels, suggesting that total cholesterol may be one of the factors that induce β-cell dedifferentiation.

Effects of pre- and post-diagnosis of malignant neoplasms total cholesterol difference on all-cause death in the Kailuan study population / 肿瘤研究与临床

Objective:To explore the effects of pre- and post-diagnosis of malignant neoplasms total cholesterol difference on all-cause death in the Kailuan study population.Methods:A prospective cohort study method was used to observe on the job and retired workers who were diagnosed with malignant neoplasms during the healthy physical examination and had the complete data of total cholesterol pre- and post-diagnosis of malignant neoplasms at Kailuan (Group) Limited Liability Corporation from June 2006 to December 2015. Medical insurance system and medical records case management system of Kailuan General Hospital were used to retrieve the confirmed diagnosis time of participants with malignant neoplasms. SAS 9.4 software was used to extract the physical examination data of participants diagnosed as malignant neoplasms before and after 2 years. The whole participants were divided into 4 groups according to the quartile of the total cholesterol difference pre- and post-diagnosis of cancer. The first quartile group: the total cholesterol difference <-0.93 mmol/L (823 cases), the second quartile group: the total cholesterol difference≥-0.93 mmol/L and <-0.21 mmol/L (811 cases), the third quartile group: the total cholesterol difference≥-0.21 mmol/L and <0.49 mmol/L (832 cases), the forth quartile group: the total cholesterol difference≥0.49 mmol/L (833 cases). The incidence density was used to calculate the mortality of different total cholesterol difference quartile groups, and the Cox proportional hazards model was used to analyze the influencing factors of all-cause death of all quartile groups.Results:Totally, 1 564 cases had all-cause death during median 2.46 years of follow-up time. There were 481, 440, 333, 310 death cases respectively of 4 quartile groups. The death rates of all quartile groups were 230.10/1 000 person-years, 163.90/1 000 person-years, 115.34/1 000 person-years, and 83.44/1 000 person-years respectively ( χ2 = 604.62, P < 0.001). After adjusting for confounding factors, the Cox proportional hazards model analysis showed that compared with the first quartile group, the hazard ratio with the 95% confidence interval of all-cause death in the second, third, and fourth quartile groups was 0.86 (0.76-0.98), 0.62(0.54-0.72) and 0.58 (0.50-0.67) respectively (all Ptrend < 0.001). After adjusting for confounding factors of patients with cancer in different location, the forth quartile group except for cancer in thyroid, breast, prostate, testis and urinary system, all Ptrend was less than 0.05 compared with that of the first quartile group. Conclusion:Among Kailuan study population, the smaller decline or even rise in total cholesterol level of post-diagnosis compared with that of pre-diagnosis is a protective factor of all-cause death.

Cholesterolemia and triglyceridemia changes in adult with malaria in a hypo-endemic malaria region, Butembo-DR Congo

changes occur commonly among patients affected with malaria. This study aimed to assess lipid changes in blood among patients with malaria in Butembo, a hypoendemic region. Methods: This cross-sectional study, conducted in the Departments of Internal and Parasitology of Matanda Hospital, located in Butembo, from July 1st, 2020, to November 2, 2020; involved 100 patients diagnosed with malaria. Biochemical analyses carried out by three lab technicians were performed among patients who had positive malaria using positive thick film. Plasmodial species, the parasite density, the triglycerides, the total cholesterol, the HDL-cholesterol, the LDL-cholesterol were assessed. Results: Cholesteroleamia and HDLemia demonstrated a low level in 93% and in 61% of participants respectively; whereas 73% of cases showed an increased level of triglycerides in the blood. Lipidemia profile was independently associated with parasite density among patients with malaria. Conclusion: Although the lipid changes in the blood are not specific in the diagnosis of malaria, this study highlighted their status among patients with malaria. Further researches should be conducted to determine their impact on malaria outcomes. Therefore, dyslipidemia could be used in malaria screening.

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.

Ameliorative effect of hot spring bathing on the elevation of blood lipid in population / 上海预防医学

Objective To explore the effect of typical hot spring bathing of Guizhou Province on dyslipidemia, which could provide scientific basis for clarifying the physiotherapy effect of hot springs. Methods The typical hot spring sites of three main types(hydrothermal hot spring, warm mineral hot spring and metasilicate hot spring)in Guizhou Province were selected as investigation sites. 189 residents with hyperlipidemia near the investigation sites were selected as subjects and were treated with hot spring baths for 4 weeks, once a day, 5 times a week and 40-50 minutes each time. The age and gender distribution of the subjects were obtained by a questionnaire. The levels of TC, TG, LDL-C and HDL-C in serum were measured by automatic biochemical analyzer at baseline and at the end of hot spring baths. The differences of the three kinds of hot spring baths on improvement rate of dyslipidemia, the changes of abnormal blood lipid indexes and their improvement rates were compared. Results After baths of hydrothermal hot springs, warm mineral hot springs and metasilicate hot springs, the improvement rates of abnormally elevated lipids were 15.6%, 40.4% and 47.9%, respectively. The improvement rates of abnormally elevated lipids after baths of warm mineral hot springs and metasilicate hot springs were significantly higher than that after hydrothermal spring baths(all P < 0.05). Compared with before hot spring bathing, the levels of TC, TG, LDL-C and non-HDL-C in serum significantly decreased in all three kinds of hot springs. Moreover, the degree of decrease of TG in serum and the improvement rate of abnormal TG after baths of warm mineral spring and metasilicate hot spring were significantly higher than that after hydrothermal spring baths. The degree of decrease of LDL-C in serum and the improvement rate of abnormal LDL-C after baths of metasilicate hot spring were significantly higher than that after baths of hydrothermal spring and warm mineral spring(all P < 0.05). Conclusion The three types of typical hot spring baths in Guizhou Province can mitigate the elevation of blood lipid. Compared with hydrothermal spring, warm mineral spring and metasilicate hot spring may have better improvement effect on blood lipid elevation due to their more significant improvement effect on abnormal elevation of TG and LDL-C in serum.
