Tetramethylpyrazine and paeoniflorin combination(TMP-PF)alleviates atherosclerosis progress by reducing hyperlipemia and inhibiting plaque angiogenesis via the NR4A1/VEGFR2 pathway

Atherosclerosis remains a great threat to human health worldwide.Previous studies found that tetramethylpyrazine(TMP)and paeonifl orin(PF)combination(TMP-PF)exerts anti-atherosclerotic effects in vitro.However,whether TMP-PF improves atherosclerosis in vivo needs further exploration.The present study aims to assess the anti-atherosclerotic properties of TMP-PF in ApoE^(-/-)mice and explore the related molecule mechanisms.Results showed that TMP and high-dose TMP-PF decreased serum triglyceride and low-density lipoprotein cholesterol levels,suppressed vascular endothelial growth factor receptor 2(VEGFR2)and nuclear receptor subfamily 4 group A member 1(NR4A1)expression in aortic tissues,inhibited plaque angiogenesis,reduced plaque areas,and alleviated atherosclerosis in ApoE^(-/-)mice.Also,TMP-PF exhibited a better modulation effect than TMP or PF alone.However,NR4A1 agonist abolished the anti-atherosclerotic effects of TMP-PF.In conclusion,TMP-PF was first found to alleviate atherosclerosis progression by reducing hyperlipemia and inhibiting plaque angiogenesis via the NR4A1/VEGFR2 pathway,indicating that TMP-PF had a positive effect on reducing hyperlipemia and attenuating atherosclerosis development.

CLINICAL ANALYSIS ON TREATMENT OF 40 CASES OF HYPERLIPEMIA WITH POINT-INJECTION OF RADIX SALVIAE MILTIORRZHIZAE INJECTION

In the present paper, the effect of point-injection of Radix Salviae Miltiorrhizae injectio on blood-lipid was observed in 65 cases of hyperlipemia. The 65 patients were divided into point-injection group (40 cases who were treated with point-injection of Radix Salviae Miltiorrhizae injectio and oral administration of Shujiangzhi) and control group (25 cases who were treated with oral administration of Shujiangzhi only). Results showed that the total effective rate of the point-injection group was significantly higher than that of the control group (P<0. 05); point-injection of Radix Salviae Miltiorrhizae injectio could effectively raise the level of HDL-C, decrease lower LDL-C and regulate estrogen level of women. The slow releasing action of red sage root solution in the topical acupoint region prolonged and enhanced its effect in lowering blood-lipid. There was a significant difference between the two groups in the effect of lowering blood-fat (P< 0. 01).

EXPERIMENTAL STUDY ON THE PREVENTION AND TREATMENT EFFECT OF WARMING-REINFORCING METHOD ON RABBIT'S HYPERLIPEMIA

In this experiment, the contents of serum total cholesterol (TC), triglyceride(TG),low-density lipoprotein(LDL), high-density lipoprotein(HDL) were used as indexes to observe the effects of warming-reinforcing method on rabbit’s lipide, liopoprotein. The results indicated that in the warming-reinforcing group, TC decreased markedly and HDL increased obviously with significant difference as compared with the twirling-reinforcing group:TC and LDL also decreased, but no significant differencte as compared with the twirling-reinforcing group. Warming-reinforcing method can decrease lipids more effectively than twirling-reinforcing method.

Severe hyperlipemia-induced pseudoerythrocytosis - Implication for misdiagnosis and blood transfusion: A case report and literature review

BACKGROUND Severe hyperlipemia(SHLE)has an impact on the results of many kinds of laboratory tests.Complete blood count(CBC)examination by automated blood cell counter(ABCC)is a quick and convenient measurement for screening abnormalities of blood cells that are triggered by various pathogenic insults in disease diagnosis and for monitoring changes in the treatment of existing hematological conditions.However,CBC results are frequently affected by many intrinsic and extrinsic factors from blood samples,such as in the setting of hypergammaglobulinemia and certain anticoagulants.SHLE could also affect CBC results.CASE SUMMARY A 33-year-old Chinese male presented with painful foot numbness and abdominal pain.He was initially misdiagnosed as having a myeloproliferative neoplasm(MPN)because of the marked abnormalities in CBC examination by the ABCC.Morphological evaluation of the bone marrow smears and biopsy showed no evidence of MPN.Gene mutations in Breakpoint cluster regions-Abelson murine leukemia viral oncogene homologue 1(BCR-ABL1),Janus kinase 2(JAK2),calreticulin(CALR),myeloproliferative leukemia virus(MPL),and colony-stimulating factor 3 receptor(CSF3R)were negative.Having noticed the thick chylomicron layer on blood samples and the dramatically fluctuating CBC results,we speculated that the fat droplets formed by shaking the blood samples in the setting of SHLE were mistakenly identified as blood cells due to the limited parameters of ABCC.Therefore,we removed a large part of the chylomicron layer and then reexamined the CBC,and the CBC results,as we expected,differed significantly from that of the sample before the chylomicron layer was removed.These significant differences had been validated by the subsequently repeated laboratory tests by measuring dual blood samples that the chylomicron layer was removed in one sample and was not in another,and comparing the CBC results.Computerized tomography reexamination of the upper abdomen revealed an exudative lesion surrounding his pancreas.After intensive consultation,definitive diagnosis was made as recurrent pancreatitis,hyperlipemia and pseudoerythrocytosis.CONCLUSION SHLE may become a potential cause of misdiagnosis of hyperlipemia-related diseases as MPNs and the resultant mistreatment.It may also lead to the misinterpretation of transfusion indications in patients with hematological disorders who critically need blood transfusion for supportive treatment.

The Alimentary Therapy for Hyperlipemia Complicated with NIDDM

Hyperlipemia is a complication commonly seen in non-insulin-dependent diabetes(NIDDM).This complication can causeischemic heart disease,cerebro-vascular disease and even lifethreatening.In order to prevent this complication and to reduce mortality of NIDDM,60patients with NIDDMand hyperlipemia were investigated.Alimentary therapy consisting of the following items was given:(1)routine control of total calorie consumption:(2)carbohydrates,lipids,proteins,vitamins and minerals taken in proportional amounts;(3)fish proteins were the main proteins in the diet;(4)dried mushroom(3g/day);(5)little tea after meal;(6)corn meal or millet gruel(5-10g./day).With this dietary regime,majority of the NIDDMpatiens with serum total lipid returned to normal or near normal.

Objective: To observe the effect of herb-medicine-cake-separated moxibustion on serum lipoprotein in hyperlipemia rabbits. Methods: 55 New-Zealand rabbits were randomly divided into control group (n=13), model group (n=14), direct moxibustion group (n=14) and herb-medicine-cake-separated moxibustion (indirect moxibustion) group (n=14). Hyperlipemia model was established by feeding the animals with specialized forage (15% vitellus powder, 5% lard, 0.5% cholesterol and common forage) for 6 weeks. Moxibustion was applied to “Juque”(CV 14), “Tianshu”(ST 25), “Fenglong”(ST 40), etc., 4 moxa-cones for every acupoint, once daily and continuously for 40 days. Serum high density lipoprotein-cholesterol (HDL-Ch), low density lipoprotein-cholesterol (LDL-Ch) and total cholesterol (TCh) contents were assayed with colorimetric method. Results: Compared with control group, serum LDL-Ch content, HDL-Ch/LDL-Ch and HDL-Ch/TCh of model group were significantly higher (P<0.05～0.01), while compared with model group, LDL-Ch contents of two moxibustion groups were strikingly lower (P<0.01). No significant differences were found between two moxibustion groups in all the 4 indexes. Conclusion: Both direct and indirect moxibustion can effectively lower serum LDL-Ch, raise HDL-Ch, HDL-Ch/LDL-Ch and HDL-Ch/TCh, and regulate lipoprotein metabolism in hyperlipemia rabbits.

EFFECT OF HERB-MEDICINE-CAKE-SEPARATED MOXIBUSTION ON SERUM LIPOPROTEIN CONTENTS IN HYPERLIPEMIA RABBITS

Objective: To study the effect of medicinal herb-cake-separated moxibustion on serum lipoprotein levels in hyperlipemia rabbits. Methods: A total of 55 New-Zealand rabbits were randomly divided into control group (n=13), model group (n=14), direct moxibustion group (n=14) and medicinal herb-cake-separated moxibustion (indirect moxibustion) group (n=14). Hyperlipemia model was established by feeding the animals with specialized forage (15% vitellus powder, 5% lard, 0.5% cholesterol and common forage) for 6 weeks. Moxibustion was applied to “Juque”(CV 14), “Tianshu”(ST 25), “Fenglong”(ST 40), etc., 4 moxa-cones for every acupoint, once daily and continuously for 40 days. Serum triglyceride (TG) and total cholesterol (TCh) contents were assayed with colorimentric method. Results: Compared with control group, TCh and TG levels of model group increased significantly (P< 0.01). TCh and TG contents of direct moxibustion and indirect moxibustion groups were significantly lower than those of model group (P<0.01). Comparison between two moxibustion groups showed that serum TCh level of indirect moxibustion group was strikingly lower than that of direct moxibustion group (P<0.01). It indicated that both direct and indirect moxibustion could effectively lower hyperlipemia and the therapeutic effect of indirect moxibustion was significantly superior to that of direct moxibustion in lowering serum TCh level. Conclusion: Both direct and indirect moxibustion can regulate lipid metabolism and the therapeutic effect of medicinal herb-cake-separated moxibustion is superior to that of direction moxibustion in hyperlipemia rabbits.
