ABSTRACT
Objective To study the effect of Shenlingbaizhu Pills on hyperlipidemia and gut microbiota in guinea pigs, providing data support for the treatment of hyperlipidemia from the " spleen" . Methods Guinea pigs were randomly divided into control group, model group, ezetimibe group, Shenlingbaizhu Pills high and low dose groups, with 12 guinea pigs for each group. Guinea pig models of hyperlipidemia were established with high fat diet for 8 weeks. Oral administration of the drug began at the fifth week and continued for 4 weeks. The serum lipid levels of guinea pigs were determined after final administration. The pathological changes of liver tissue were observed by HE staining. The mRNA expression levels of ATP binding cassette ( ABC ) A1 in liver, Niemann Pick C1 like 1 ( NPC1L1) and ABCG5/8 in small intestine were detected by realtime PCR. 16S rDNA sequencing was used to detect changes of gut microbiotas in guinea pigs. Results Shenlingbaizhu Pills significantly reduced the serum triglyceride, total cholesterol, and low density lipoprotein-cholesterol levels in guinea pigs with hyperlipidemia ( P＜0. 01 or P＜0.05). The pathological degree of fatty liver was improved obviously by Shenlingbaizhu Pills. Shenlingbaizhu Pills could reduce the mRNA expression level of NPC1L1 of small intestine and increase the level of liver ABCA1 and small intestine ABCG5/8 (P＜0.01 or P＜0.05). At the phylum level, Shenlingbaizhu Pills could reduce the proportion of verrucomicrobia of guinea pigs in model group (P＜0.01); At the genus level, Shenlingbaizhu Pills could increase the proportions of erysipelotrichaceae＿unclassified, ruminococcus＿1, and ileibacterium of guinea pigs in model group (P＜0. 01 or P＜0. 05 ), reduce the proportion of akkermansia and eubacterium＿coprostanoligenes＿group ( P＜0.01). Conclusion Shenlingbaizhu Pills had significantly therapeutic effect on hyperlipidemia, and its specific mechanism was related to the regulation of cholesterol transport and intestinal flora.
ABSTRACT
OBJECTIVE: To observe the clinical effect of Shengxueling Granule (SXLG) in treating idiopathic thrombocytopenic purpura (ITP), and to study its possible mechanism. METHODS: Eighty-six cases of ITP were divided into two groups randomly. Fifty-six cases in the treatment group were treated with SXLG, a traditional Chinese medicine, and 30 cases administered with Western medicine (prednisone) were taken as control. Patients in each group took drugs for three months and were under follow-up observation. RESULTS: In SXLG-treated group, the total effective rate in 3 months was 85.71%, similar to 83.33% in prednisone-treated group (P>0.05), while the total effective rate in 6 months in the SXLG-treated group was 91.07%, higher than 53.33% of the prednisone-treated group (P<0.01), and no obvious side-effects were observed. The patients' bleeding was alleviated or stopped, and their general condition was improved. And the blood platelet count (BPC) was increased, the platelet associated immunoglobulin (PAIg) and interleukin-4 (IL-4) were markedly dropped, the level of natural killer cells activity (NKCA) increased, and the rate of T lymphocyte subsets gradually returned to normal level. Megakaryocytes tended toward maturation on bone marrow smear after SXLG treatment. All differences above were statistically significant. CONCLUSION: SXLG is an effective and safe medicine for ITP. It can regulate the cellular immunity, inhibit the platelet antibody to reduce the destruction of the platelet and to increase the number of platelet, promote the differentiation and maturation of megakaryocyte, facilitate the production and release of platelet, lower the fragility of capillary, and prevent the hemorrhagic tendency.
