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).

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.

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.

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.
