ObjectiveThe study aims to investigate the intervention effect of modified Xiangsha Liujunzitang （M-XSLJZ） on intestinal-derived lipopolysaccharide （LPS）-activated Kupffer cell inflammation in rats with hyperlipidemia spleen deficiency syndrome. MethodsSeventy male SD rats were randomly divided into seven groups （n=10）： blank control （CON）， high-fat diet without spleen deficiency （HFD）， high-fat diet with spleen deficiency （SD-HFD）， M-XSLJZ low-， medium-， and high-dose groups （XS-L， XS-M， XS-H）， and western medicine control （R）. Spleen deficiency was induced in SD-HFD， XS-L， XS-M， XS-H， and R groups via irregular diet combined with exhaustive swimming for 15 days. The CON group received a standard diet， while other groups were fed a high-fat diet for 10 weeks to establish the hyperlipidemia model. After successful modeling， rats were treated for 8 weeks： M-XSLJZ was administered at 3.51， 7.02， 14.04 g·kg^-1 in XS-L， XS-M， and XS-H groups， respectively. The R group received 9×10^-4 g·kg^-1 of a reference drug. D-xylose excretion rate was measured by the phloroglucinol method. Blood lipids were assessed using an automated biochemical analyzer. Hematoxylin-eosin （HE） staining was used to evaluate the pathological conditions of the liver， and oil red O staining was used to observe the lipid deposition in the liver. The levels of LPS， portal vein serum LPS， LPS-binding protein （LBP）， serum interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence was used to evaluate CD86 expression and CD68/TLR4 co-localization in the liver. Protein levels of TLR4， MyD88， NF-κB p65， and p-NF-κB p65 in Kupffer cells were analyzed via Western blot automated protein analysis. Hepatic IL-6， TNF-α， and IL-1β mRNA and protein levels were measured using Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared with the CON group， the SD-HFD group showed a decrease in D-xylose excretion （P<0.01）. TC， TG， HDL-C， and LDL-C increased （P<0.05， P<0.01）. A large number of hepatic lipid vacuoles and orange-red lipid droplet deposition appeared in the liver. Ileal LPS， portal LPS， and LBP increased （P<0.05， P<0.01）. The levels of serum IL-6， TNF-α， and IL-1β increased （P<0.01）. The expression of CD86 was upregulated （P<0.01）， and the co-expression of CD68 and TLR4 was enhanced. The protein levels of TLR4， MyD88， and p-p65 in Kupffer cells increased （P<0.01）. The mRNA and protein levels of IL-6， TNF-α， and IL-1β increased （P<0.05， P<0.01）. Compared with the HFD group， the SD-HFD group exhibited decreased D-xylose excretion （P<0.01）， higher HDL-C， LDL-C （P<0.05）， increased portal LBP and LPS （P<0.05）， increased serum IL-6 and TNF-α （P<0.01）， upregulated CD86 （P<0.01）， enhanced CD68/TLR4 co-expression， and higher TNF-α mRNA/protein （P<0.05）. Compared with the SD-HFD group， all M-XSLJZ treatment groups showed reduced TC， TG， and LDL-C （P<0.05， P<0.01）. XS-H and R groups displayed improved hepatic lipid deposition. XS-H and R groups had lower ileal LPS， portal LPS， and LBP levels （P<0.05， P<0.01）. All M-XSLJZ treatment groups exhibited reduced serum IL-6， IL-1β， and TNF-α （P<0.01）. The XS-H group showed downregulated CD86 （P<0.01） and weakened CD68/TLR4 co-expression. The XS-H group had reduced TLR4， MyD88， and p-NF-κB p65 in Kupffer cells （P<0.01）. XS-H and R groups showed lower IL-6， TNF-α， and IL-1β mRNA/protein （P<0.05， P<0.01）. ConclusionM-XSLJZ may exert its lipid-lowering effects by inhibiting intestinal-derived LPS and alleviating Kupffer cell inflammation in the liver.

The key pathogenesis of coronary heart disease （CHD） is spleen deficiency and phlegm stasis， and dysfunctional high-density lipoprotein （dys-HDL） may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein （HDL）， it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL； and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways， namely， mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells， thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency， and spleen deficiency makes foundation for the production of dys-HDL； dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen， resolving phlegm， and dispelling stasis， is proposed as an important principle in the treatment of CHD by traditional Chinese medicine， which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL， thus revealing the scientific connotation of this method， and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.
