Clinical Value of Hospital-Community-Family Integrated Nursing Model in the Treatment of Patients with Hyperlipidemia Pancreatitis.

Objective: This study aimed to observe the impact of the hospital-community-family integrated nursing paradigm on the compliance, psychological state, and blood lipid levels in patients with hyperlipidemia pancreatitis (HLP). Methods: Totally 66 HLP patients treated in our institution between June 2018 and June 2021 were randomized to Exp group and Con group. The Exp group received the hospital-community-family integrated nursing mode, whereas Con group adopted conventional nursing. Outcome measures included patient compliance, mental state, and blood cholesterol levels. Results: Patients with integrated nursing exhibited markedly higher compliance than those with conventional nursing, as evinced by higher scores of compliance behavior, compliance awareness, medication attitude, and treatment attitude (P < 0.05). Integrated nursing offered more potent mitigation of negative emotions of patients than conventional nursing (P < 0.05). Integrated nursing resulted in better enhanced quality of life of patients versus conventional nursing (P < 0.05). Superior blood lipid amelioration was observed in patients after integration nursing versus those after conventional nursing, demonstrated by a higher serum high-density lipoprotein (HDL) level, and lower levels of triglycerides (TG), cholesterol (TC), and low-density lipoprotein (LDL) (P < 0.05). Patients were more satisfied with integrated nursing (96.97%) than conventional nursing (72.73%), suggesting a high patient acceptance of the nursing mode (P < 0.05). Conclusion: The hospital-community-family integrated nursing model provides a viable alternative to enhance HLP patients' compliance and optimize their psychological state and blood lipid levels, demonstrating good potential for clinical promotion.

Retrospective analysis and preliminary laboratory validation of treatment efficacy and blood lipid levels in patients with rheumatoid arthritis.

OBJECTIVE: Rheumatoid arthritis is a systemic disease characterized by progressive chronic inflammation resulting in destruction of synovial joints. In addition to joint involvement, abnormal blood lipid indexes have also been found in RA patients. The correlation between various blood lipid indexes and the treatment effects were assessed in patients with rheumatoid arthritis, for the purposes to find a better medication strategy for RA. METHODS: One hundred nineteen rheumatoid arthritis patients were recruited and divided into two groups, 45 patients with significant drug treatment effect and 45 patients with insignificant drug treatment effect through the nearest neighbor matching method in propensity score. The correlation between various blood lipid indexes and drug treatment effect of rheumatoid arthritis patients was analyzed. A mouse model of rheumatoid arthritis was constructed in the laboratory; methotrexate was treated as a positive drug. We observe and record the onset of rheumatoid arthritis in mice, as well as the proportion of immune cells, the expression of inflammatory factors, and the changes in blood lipid profiles was done. RESULTS: The levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), and erythrocyte sedimentation rate (ESR) in rheumatoid arthritis patients were significantly different between the two groups (P < 0.05). There was no significant difference in other indexes between the two groups (P > 0.05). Methotrexate had a good therapeutic effect on CIA model mice, and the levels of TC and HDL-C in the treatment group were higher than those in the model group. CONCLUSION: There is a high correlation between the levels of TC and HDL-C in rheumatoid arthritis patients and the effect of drug treatment. In the clinical treatment of rheumatoid arthritis, we should focus on improving the blood lipid indexes such as TC and HDL-C, and explore more targeted individualized administration, so as to achieve better and faster treatment effect in patients with rheumatoid arthritis. Key Points • In this research, we found that the TC and HDL-C level in RA patients' blood is highly related with the therapeutic effect, and a lower level of TC and HDL-C is better for therapeutic effect of RA.

Synergistic effect of blood lipids and uric acid on periodontitis in patients with type 2 diabetes.

OBJECTIVE: This study investigated the interaction of dyslipidemia and hyperuricemia on periodontitis in patients with type 2 diabetes mellitus (T2DM). METHODS: The clinical data of 220 patients with T2DM (diabetes group) treated in Tianjin Baodi Hospital from January 2019 to December 2021 were retrospectively analyzed. Another 200 healthy subjects in the same period were selected as the control group. The correlation of hyperuricemia and hyperlipidemia with diabetes was tested by the spearman correlation coefficient. Multivariate logistic regression was used to analyze the multiplicative interaction and additive interaction of dyslipidemia and hyperuricemia on periodontitis. RESULTS: Diabetes was positively correlated with hyperuricemia and hyperlipidemia (P<0.05). Patients with dyslipidemia (OR = 8.107, 95% CI: 2.687-24.457) and hyperuricemia (OR = 2.940, 95% CI: 0.970-8.909) had a higher risk of periodontitis, but there was no multiplicative interaction effect of dyslipidemia and hyperuricemia on periodontitis (OR = 1.864, 95% CI: 0.256-13.545, P>0.05). The risk of developing diabetes was higher in individuals with dyslipidemia and hypertension than in those without (OR = 2.887, 95% CI: 1.478-4.855). The evaluation indexes of the combined interaction effect relative excess risk due to interaction, interaction attribution percentage and synergy index were 0.902 (95% CI: 0.379-1.496), 0.273 (95% CI: 0.106-0.458) and 1.485 (95% CI: 0.978-2.165), respectively. CONCLUSION: Dyslipidemia and hyperuricemia may have a synergistic effect on periodontitis in people with T2DM. Improving blood lipids and controlling blood uric acid may synergistically prevent periodontitis.

[Interaction between Abnormal Prepregnancy Body Mass Index and Hyperlipidemia during Pregnancy on the Risk of Gestational Diabetes Mellitus].

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.

A study on the nutritional and biochemical analysis of Selaginella tamariscina powder.

This study reports the various nutritional components of Selaginella tamariscina, which is traditionally used in folk or Chinese medicine. The iron nutrient content in S. tamariscina powder was 0.94 ± 0.06 mg/100 g powder, whereas selenium was present in a small amount, which showed strong antioxidant power. The total phenolic content of S. tamariscina powder was 8.65-11.61 mg gallic acid equivalents/g. S. tamariscina showed antioxidant activity in 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The ferric reducing antioxidant power of S. tamariscina powder was higher in the ethanol extract. Additionally, the ethanol extract demonstrated antimicrobial activity against Bacillus subtilis KCTC 2189. The level of high-density lipoprotein-cholesterol in the blood of ICR mice was significantly higher in the HF 20% + S. tamariscina 20% group than in the other groups (p < 0.05). The present study demonstrates that S. tamariscina, an abundantly existing plant, possesses antimicrobial, antioxidant, and anticytotoxic activities. S. tamariscina powder has potential as a functional food.

An Eight Year Experience of Autologous Oocyte Vitrification for Infertile Patients Owing to Unavailability of Sperm on Oocyte Retrieval Day.

Objective: The objective of this study was to provide a descriptive analysis of the clinical outcomes achieved in oocyte vitrification in cases where sperm was unavailable on oocyte retrieval day, and to identify predictors of oocyte survival. Methods: This retrospective cohort study used data from a university-affiliated reproductive medical center. There were 321 cycles in which some of, or all oocytes were vitrified owing to the unavailability of sperm between March 2009 and October 2017. A descriptive analysis of the clinical outcomes including both fresh embryo transfers and cryopreserved embryo transfers was provided. The ability of an individual parameter to forecast oocyte survival per thawing cycle was assessed by binary logistic regression analysis. The cumulative probability of live birth (CPLB) was estimated by using the Kaplan-Meier method according to the total number of oocytes thawed in consecutive procedures. Results: The average survival rate was 83.13%. High-quality embryo rate and blastocyst rate decreased significantly decreased significantly in vitrification oocyte group compared to fresh control oocytes. The comparison of sibling oocytes in part-oocyte-vitrified cycles shows fewer high-quality embryos developed in the vitrified group. The live birth rate per warmed-oocyte was 4.3%. Reasons for lack of sperm availability on oocyte retrieval day and serum cholesterol levels were found to be associated with oocyte survival rate in the present study. Kaplan-Meier analysis showed no significant difference in CPLB between patients ≤35 vs. >35 years. Conclusions: Oocyte vitrification is an indispensable and effective alternative when sperm are not available on oocyte retrieval day. The present study provided evidence that oocytes from infertile couples were more likely to suffer oocyte/embryo vitrification injury. Clinicians need to take this into account when advising patients in similar situations. Further studies will be necessary to clarify the correlation between serum metabolism parameters and human oocyte survival after vitrification.

The effect of art therapy on reoccurring smoking among youths.

OBJECTIVE: To evaluate the effect of art therapy on reoccurring smoking among youths. METHODS: A total of 114 smokers admitted to the smoking cessation clinic of our hospital were enrolled and randomly divided into the control group (n=61) and the study group (n=53). The control group was given health education intervention, and the study group was given art therapy intervention. The blood lipid level, symptom checklist score, lung function, and high-density lipoprotein cholesterol (HDL-C) and serum total cholesterol (TC) levels of different length of smoking were compared between the two groups. RESULTS: The levels of low-density lipoprotein cholesterol (LDL-C), TC, triglycerides (TG), HDL-C were significantly reduced in both groups, but compared with the control group, the LDL-C, TC, TG, and HDL-C levels of the study group were decreased more significantly, and the difference was statistically significant (P<0.05). The symptom checklist scores were significantly reduced in both groups, but compared with the control group, the study group decreased more significantly, and the difference was statistically significant (P<0.05). There were significant differences in HDL-C levels among young smokers who had different length of smoking (P<0.05), and with the continuous increase in smoking years, HDL-C levels were significantly reduced. After intervention, lung function was significantly improved, and the levels of vital capacity (VC%) and forced expiratory volume in the first second (FEV1%) were significantly increased (P<0.05). After intervention, the smoking reduction rate and the success rate of time-point smoking cessation were significantly reduced (P<0.05). CONCLUSION: Art therapy intervention had an ideal effect on young smokers, which could improve blood lipid levels and lung function, reduce the rate of reoccurring smoking, and significantly increase patients' symptom checklist score.

Effects of Copper Supplementation on Blood Lipid Level: a Systematic Review and a Meta-Analysis on Randomized Clinical Trials.

Studies have evaluated the effect of copper (Cu) supplementation on blood lipid level. We therefore investigated whether the supplement of Cu on blood lipid level will have an impact in a meta-analysis on randomized controlled trials (RCTs). Literature search was conducted in Scopus, PubMed, Web of Science, and Cochrane Library (from database to January 2020). Randomized controlled trials of Cu supplementation on blood lipid level were retrieved according to the requirements of systematic review, and the quality of the included research was evaluated. Then the meta-analysis was performed. Data from 5 trials representing 176 participants were examined. Pooled mean net change in total cholesterol (TC) (standard mean difference(SMD) [95% CI] = - 0.05 [- 0.52, 0.43]), low density lipoprotein cholesterol (LDL-C) (SMD [95% CI] = 0.22 [- 0.46, 0.89]), and high density lipoprotein cholesterol (HDL-C) (SMD [95% CI] = 0.18 [- 0.14, 0.49]) for those treated with Cu supplementation had no significant difference when compared with control. Cu supplementation has not affected blood lipids in the result of meta-analysis. More research is needed to determine if this pattern will apply broadly.

Distribution of ApoE polymorphism and its correlation with blood lipid level and type of coronary heart disease in Shaanxi / 西安交通大学学报(医学版)

【Objective】 To explore the distribution of ApoE polymorphism in Shaanxi province and its correlation with lipid level and coronary heart disease type. 【Methods】 ApoE genotypes in the whole blood of 11 533 patients with cardiovascular diseases admitted to The First Affiliated Hospital of Xi’an Jiaotong University from January 2019 to December 2019 were detected by PCR-fluorescent probe method. Then 3 884 patients with coronary heart disease were selected to detect the lipid level and classified for the analysis of ApoE polymorphism. 【Results】 The proportion of E2/E2, E2/E3, E3/E3, E2/E4, E4/E4 and E3/E4 was 0.69%, 11.66%, 70.31%, 1.17%, 0.83% and 15.34%, respectively. E3 genotype was the highest (71.48%), followed by E4 (16.17%), and E2 was the least (12.35%). There was no statistical difference in the distribution of ApoE polymorphism in patients with cardiovascular disease accompanied with or without coronary heart disease. Compared with those of E2, the total cholesterol (TC) and low-density lipoprotein (LDL-C) levels of E3 and E4 increased significantly (P0.008 3). 【Conclusion】 The polymorphism of ApoE in Shaanxi is mainly E3 type, and there is no statistical difference in the distribution of coronary heart disease and other cardiovascular diseases. ApoE gene polymorphism is correlated with blood lipid level and coronary heart disease, but the relationship with different types of coronary heart disease needs to be further determined.

[Lipid-lowering effect and mechanism of Danhong Injection on hyperlipidemia rats based on lipid metabolism disorder].

The animal model of hyperlipidemia in rats was established to investigate the lipid-lowering effect and mechanism of Danhong Injection on hyperlipidemic rats. SD rats were selected as the research object. The rats in normal group were fed with basic diet, and the rats in other groups were fed with high-fat diet to establish hyperlipidemia model. The successfully modeled rats were randomly divided into model group, Danhong Injection low, medium, high dose(1.0, 2.0, 4.0 mL·kg~(-1)) groups, and simvastatin(2.0 mg·kg~(-1)) group. Danhong Injection groups received intraperitoneal administration, and simvastatin group received intragastrical administration, once a day for 4 weeks. At the first, second, third, and fourth weekends after administration, blood was collected from the orbital vein to detect the levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-C), and high-density lipoprotein cholesterol(HDL-C), and then the atherosclerosis index(AI) was calculated. After 4 weeks of administration, the animals were sacrificed, and their heart, liver, spleen, lung, kidney and adipose tissue were extracted and weighed respectively to calculate the organ index of each group. The expressions of acyl-coaoxidase 1(Acox1), adenosine 5'-monophosphate(AMP)-activated protein kinase alpha(AMPK-α), bile salt export pump(BSEP), peroxisome proliferator-activated receptor gamma(PPAR-γ), catalase(CAT) and superoxide dismutase(SOD) mRNA in liver tissues were detected by fluorescence quantitative PCR; the content of cholesteryl ester transfer protein(CETP) and lecithin cholesterol acyltransferase(LCAT) in serum was detected by ELISA. The results showed that as compared with the normal group, the levels of serum TC, TG and LDL-C in the model group were significantly increased, and the level of HDL-C was significantly decreased, indicating that the hyperlipidemia rat model was successfully constructed. As compared with the model group, Danhong Injection could decrease the contents of TC, TG, LDL-C and increase the content of HDL-C in hyperlipidemia rats; reduce the body weight of hyperlipidemia rats, and reduce the liver weight, liver index, fat weight and fat index; it had no significant effect on the main organ indexes such as heart, spleen, lung and kidney; but it could increase the expressions of Acox1, AMPK-α, BSEP, PPAR-γ, CAT and SOD mRNA in liver tissues of rats; it could also reduce the level of CETP and increase the level of LCAT in serum; and the regulatory effect of Danhong Injection groups all showed a dose-dependent effect. It can be concluded that Danhong Injection can regulate the blood lipid contents, reduce the blood lipid levels and alleviate the accumulation of body fat in rats with hyperlipidemia. The mechanism may be related to inhibiting lipid metabolism disorder and oxidative stress induced by high-fat diet feeding, and improving the imbalance of lipid transport system.

[Meta-analysis of Zhibitai Capsules combined with statin in reducing blood lipid levels in patients with coronary heart disease].

To systematically review the efficacy and safety of Zhibitai Capsules combined with chemical drugs versus chemical drugs alone in regulating blood lipid of patients of coronary heart disease, so as to provide evidence-based reference for clinical treatment. In this study, PubMed, EMbase, Cochrane Library, China Knowledge Network Database(CNKI), Technology Journal Database(VIP) and WanFang Database(WanFang) were retrieved to find the randomized controlled trials(RCT) about therapeutic efficacy of Zhibitai Capsules combined with statins(experimental group)versus statins alone(control group)in the treatment of regulating blood lipid of patients with coronary heart disease. The retrieval time was restricted to be from the inception to October 2019. The data were extracted from the randomized controlled trials. Meta-analysis was conducted by RevMan 5.3 statistical software after quality evaluation by Cochrane 5.1.0 quality evaluation tool(blood lipid level, inflammation indicators, traditional Chinese medicine syndrome score and adverse reactions). A total of 11 RCT were included, involving 1 538 patients. The results of Meta-analysis showed that in terms of decrease of total cholesterol(MD=-0.15,95%CI[-0.25,-0.05],P=0.004), decrease of triglycerides improvement(MD=-0.16,95%CI[-0.23,-0.10],P<0.000 01), decrease of low-density lipoprotein(MD=-0.08,95%CI[-0.15,-0.01],P=0.03), and increase of high-density lipoprotein(MD=0.06,95%CI[0.03,0.10],P=0.000 2), experimental group was better than control group. At the same time, the incidence of adverse reactions were low in the experimental group(OR=0.40,95%CI[0.18,0.85],P=0.02). As a result, in treatment of coronary heart disease, the therapeutic efficacy of Zhibitai Capsules combined with statins is better than statins alone in lowering total cholesterol level, triglyceride level, low-density lipoprotein level, and increasing high-density lipoprotein level. Patients in the experimental group had a low incidence of adverse events, but the heterogeneity was slightly higher, and the result had a poor stability. However, due to the small sample size of studies included, some experimental designs were not perfect, which reduces the recommendation level and evidence intensity of this system evaluation. Therefore, high-quality multi-center, large-sample, randomized, double-blind randomized controlled trials are needed for providing more reliable basis.

Short-term exposure to air pollution and its interaction effects with two ABO SNPs on blood lipid levels in northern China: A family-based study.

We examined the main effects of ambient particulate matters, as well as whether single-nucleotide polymorphisms (SNPs), located within ABO gene would modify the relationship. Data were collected from a family-based study conducted in Northern China. A generalized additive model with a Gaussian link and with each family as a stratum was applied to estimate the percentage change in blood lipid levels following a 10 µg/m3 increase in ambient particulate matter concentrations. Interaction analyses were conducted by including a cross-product term of PM2.5 or PM10 by SNP. Results showed that a 10 µg/m3 increase in Particulate matter with aerodynamic diameter <2.5 µm (PM2.5) concentrations corresponded to the highest 0.010% (95% CI: 0.002%-0.018%), 0.018% (95% CI: 0.006%-0.029%), 0.019% (95% CI: 0.010%-0.029%) increase in total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), respectively and 0.005% (95% CI: 0.002%-0.008%) decrease in high density lipoprotein cholesterol (HDL-C)-to-LDL-C ratio. As for the PM10, similar results were observed. Furthermore, our finding showed an interaction effect of PM10 and rs505922/rs579459 C allele on TG. Specifically, individuals carrying the rs505922 and rs579459 T allele have higher TG concentrations following PM10 exposure, with a 10 µg/m3 increase in PM10 concentrations corresponding to the highest 0.028% and 0.034% increase in TG, respectively. In conclusion, short-term exposures to ambient particulate matters are associated with a higher blood lipid level, which can be modified by ABO polymorphism. The findings may be useful in identifying vulnerable population according to genetic background.

Mechanism of Action of Trichosanthis Fructus-Allii Macrostemonis Bulbus Herb Pairs Against Hyperlipidemia Based on Network Pharmacology / 中国实验方剂学杂志

Objective:Based on the hyperlipidemia rat model and network pharmacology technology, the mechanism of action of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia was analyzed. Method:The levels of blood lipids and inflammatory factors were measured through prophylactic administration of low, medium and high-dose Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs in hyperlipidemia rats. The active ingredients of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs were screened out through Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP) and text mining. The targets of active ingredients screened through the Swiss Target Prediction, Similarity ensemble approach (SEA), DrugBank database. The disease targets were collected through Therapeutic Target Database (TTD), Online Mendelian Inheritance in Man (OMIM), DrugBank, DisGeNET database. The targets of active ingredients and disease target were integrated, and screened through topological parameters to gain the main candidate targets of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and the gene ontology (GO) functional enrichment analysis were conducted through ClueGO and Database for Annotation, Visualization and Integrated Discovery (DAVID), respectively. The traditional Chinese medicine-chemical ingredient-target network model, and the target-pathway network model were constructed through Cytoscape, and their crosstalk target and signal pathway were analyzed. Result:Animal experiments showed that the prophylactic administration of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs significantly reduced the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) in serum of rats with hyperlipidemia, increased high-density lipoprotein (HDL-C) levels, and inhibited the expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). According to the findings, 27 active ingredients, such as mandenol, diosmetin and α-spinasterol, might be the main active ingredients of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs, 16 crosstalk targets and 10 signal pathways might be the main therapeutic targets and pathways, main targeting apolipoprotein A1 (APOA1), apolipoprotein A2 (APOA2), apolipoprotein C3 (APOC3), lipoprotein lipase (LPL), low-density lipoprotein receptor (LDLR) and other crosstalk targets affected cholesterol metabolism, bile secretion, peroxisome proliferator activated receptor (PPAR) signaling pathway in regulating the lipid level, targeting tumor necrosis factor (TNF), IL-6, interleukin-1β (IL-1β), mitogen-activated protein kinase 1 (MAPK1), C-C motif chemokine 2 (CCL2) and other crosstalk targets affected tumor necrosis factor (TNF) signaling pathway, Toll-like receptor signaling pathway, interleukin-17 (IL-17) signaling pathway, and hypoxia inducible factor (HIF) signaling pathway in regulating the inflammatory factor level. The DAVID database for GO enrichment analysis showed that the hyperlipidemia was treated mainly through biological processes, such as inflammation, lipid localization, storage and lipid metabolism. Conclusion:These findings can predict the mechanism of action of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia, and provide a theoretical basis for the material basis and clinical application of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs.

The results of Meta-analysis showed that in terms of decrease of total cholesterol(MD=-0.15,95%CI[-0.25,-0.05],P=0.004), decrease of triglycerides improvement(MD=-0.16,95%CI[-0.23,-0.10],P<0.000 01), decrease of low-density lipoprotein(MD=-0.08,95%CI[-0.15,-0.01],P=0.03), and increase of high-density lipoprotein(MD=0.06,95%CI[0.03,0.10],P=0.000 2), experimental group was better than control group. At the same time, the incidence of adverse reactions were low in the experimental group(OR=0.40,95%CI[0.18,0.85],P=0.02). As a result, in treatment of coronary heart disease, the therapeutic efficacy of Zhibitai Capsules combined with statins is better than statins alone in lowering total cholesterol level, triglyceride level, low-density lipoprotein level, and increasing high-density lipoprotein level. Patients in the experimental group had a low incidence of adverse events, but the heterogeneity was slightly higher, and the result had a poor stability. However, due to the small sample size of studies included, some experimental designs were not perfect, which reduces the recommendation level and evidence intensity of this system evaluation. Therefore, high-quality multi-center, large-sample, randomized, double-blind randomized controlled trials are needed for providing more reliable basis.

Lipid-lowering effect and mechanism of Danhong Injection on hyperlipidemia rats based on lipid metabolism disorder / 中国中药杂志

The animal model of hyperlipidemia in rats was established to investigate the lipid-lowering effect and mechanism of Danhong Injection on hyperlipidemic rats. SD rats were selected as the research object. The rats in normal group were fed with basic diet, and the rats in other groups were fed with high-fat diet to establish hyperlipidemia model. The successfully modeled rats were randomly divided into model group, Danhong Injection low, medium, high dose(1.0, 2.0, 4.0 mL·kg~(-1)) groups, and simvastatin(2.0 mg·kg~(-1)) group. Danhong Injection groups received intraperitoneal administration, and simvastatin group received intragastrical administration, once a day for 4 weeks. At the first, second, third, and fourth weekends after administration, blood was collected from the orbital vein to detect the levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-C), and high-density lipoprotein cholesterol(HDL-C), and then the atherosclerosis index(AI) was calculated. After 4 weeks of administration, the animals were sacrificed, and their heart, liver, spleen, lung, kidney and adipose tissue were extracted and weighed respectively to calculate the organ index of each group. The expressions of acyl-coaoxidase 1(Acox1), adenosine 5'-monophosphate(AMP)-activated protein kinase alpha(AMPK-α), bile salt export pump(BSEP), peroxisome proliferator-activated receptor gamma(PPAR-γ), catalase(CAT) and superoxide dismutase(SOD) mRNA in liver tissues were detected by fluorescence quantitative PCR; the content of cholesteryl ester transfer protein(CETP) and lecithin cholesterol acyltransferase(LCAT) in serum was detected by ELISA. The results showed that as compared with the normal group, the levels of serum TC, TG and LDL-C in the model group were significantly increased, and the level of HDL-C was significantly decreased, indicating that the hyperlipidemia rat model was successfully constructed. As compared with the model group, Danhong Injection could decrease the contents of TC, TG, LDL-C and increase the content of HDL-C in hyperlipidemia rats; reduce the body weight of hyperlipidemia rats, and reduce the liver weight, liver index, fat weight and fat index; it had no significant effect on the main organ indexes such as heart, spleen, lung and kidney; but it could increase the expressions of Acox1, AMPK-α, BSEP, PPAR-γ, CAT and SOD mRNA in liver tissues of rats; it could also reduce the level of CETP and increase the level of LCAT in serum; and the regulatory effect of Danhong Injection groups all showed a dose-dependent effect. It can be concluded that Danhong Injection can regulate the blood lipid contents, reduce the blood lipid levels and alleviate the accumulation of body fat in rats with hyperlipidemia. The mechanism may be related to inhibiting lipid metabolism disorder and oxidative stress induced by high-fat diet feeding, and improving the imbalance of lipid transport system.

Effect of ophiopogonin D on serum lipids and intestinal flora in ApoE-/- mice with high-fat diet / 中草药

Objective: To investigate the effect of ophiopogonin D (OP-D) on blood lipids and intestinal flora in ApoE-/- mice fed with high-fat diet (HFD). Methods: A total of 24 male ApoE-/- mice, aged six weeks old, were randomly divided into control group, model group, OP-D group [0.5 mg/(kg∙d)] and simvastatin group [5 mg/(kg∙d)]. Another six male C57BL/6 mice were in blank group. After 12 weeks of HFD, the drugs were given by intragastric administration for 12 weeks. After the end of administration, fresh feces of mice were collected to detect intestinal flora. Serum of mice was separated to detect blood lipid. Liver section staining was prepared to observe the damage. Results: OP-D could reduce the weight gain of mice caused by HFD, inhibit the increase of total cholesterol and triglyceride, improve hepatic steatosis, and regulate intestinal flora imbalance. Conclusion: OP-D may regulate blood lipids and hepatic steatosis by improving intestinal flora imbalance induced by HFD in ApoE-/- mice.

In vitro studies on the interactions of blood lipid level-related biological molecules with gallic acid and tannic acid.

BACKGROUND: To provide the scientific evidence for a possible new mechanism of hypolipidemic effects of gallic acid (GA) and tannic acid (TA), the binding capacity of GA and TA with blood lipid level-related biological molecules, including fat, cholesterol and cholates, were investigated in vitro. Additionally, we attempted to study the interactions of cholates with GA and TA by spectroscopic methods, high-performance liquid chromatography electrospray-ionization mass spectrometry (HPLC-ESI-MS) analysis and molecular modeling studies. RESULTS: Our results demonstrated that both GA and TA were capable of binding with the blood lipid level-related biological molecules in vitro. The fat-binding capacity of TA was 122.1% that of GA when the addition of polyphenol was 90 mg. The inhibitory effects of GA and TA on the cholesterol solubility in mixed micelles and liquid egg yolk exhibited a dose-dependent relationship (0.5-2.0 mg mL-1 ). In cholate-binding tests, TA showed higher affinity for sodium cholate than GA at a concentration of 2.0 mg mL-1 , while no significant difference in the affinity for sodium deoxycholate was found between GA and TA. Moreover, the data of spectroscopic methods, HPLC-ESI-MS analysis and molecular modeling studies indicated that GA and TA might precipitate cholates through hydrophobic interactions and intermolecular hydrogen bonds rather than covalent bonds. CONCLUSION: The findings of the present study suggested that the binding capacity of GA and TA with blood lipid level-related biological molecules might play a crucial role in their hypolipidemic effects in animals. © 2019 Society of Chemical Industry.

Biological Activities of Lactose-Based Prebiotics and Symbiosis with Probiotics on Controlling Osteoporosis, Blood-Lipid and Glucose Levels.

Lactose-based prebiotics are synthesized by enzymatic- or microbial- biotransformation of lactose and have unique functional values. In this comprehensive review article, the biochemical mechanisms of controlling osteoporosis, blood-lipid, and glucose levels by lactose-based prebiotics and symbiosis with probiotics are reported along with the results of clinical investigations. Interaction between lactose-based prebiotics and probiotics reduces osteoporosis by (a) transforming insoluble inorganic salts to soluble and increasing their absorption to gut wall; (b) maintaining and protecting mineral absorption surface in the intestine; (c) increasing the expression of calcium-binding proteins in the gut wall; (d) remodeling osteoclasts and osteoblasts formation; (e) releasing bone modulating factors; and (f) degrading mineral complexing phytic acid. Lactose-based prebiotics with probiotics control lipid level in the bloodstream and tissue by (a) suppressing the expressions of lipogenic- genes and enzymes; (b) oxidizing fatty acids in muscle, liver, and adipose tissue; (c) binding cholesterol with cell membrane of probiotics and subsequent assimilation by probiotics; (d) enzymatic-transformations of bile acids; and (e) converting cholesterol to coprostanol and its defecation. Symbiosis of lactose-based prebiotics with probiotics affect plasma glucose level by (a) increasing the synthesis of gut hormones plasma peptide-YY, glucagon-like peptide-1 and glucagon-like peptide-2 from entero-endocrine L-cells; (b) altering glucose assimilation and metabolism; (c) suppressing systematic inflammation; (d) reducing oxidative stress; and (e) producing amino acids. Clinical investigations show that lactose-based prebiotic galacto-oligosaccharide improves mineral absorption and reduces hyperlipidemia. Another lactose-based prebiotic, lactulose, improves mineral absorption, and reduces hyperlipidemia and hyperglycemia. It is expected that this review article will be of benefit to food technologists and medical practitioners.
