OBJECTIVETo study anti-atherosclerotic mechanisms of divided functional recipes of Dahuang Zhechong pill (DHZCP) in rabbits.
METHODThe atherosclerotic rabbit model was established by high fat feeding combined with immune endothelial injury. Male New Zealand rabbits were divided into 9 groups: normal control group, model control group, Danshen positive control group, and 6 DHZCP-divided groups including divided functional recipes No. 1, 2, 3 with low and high doses for each divided recipe. After intragastric administration for 60 days, blood lipids and serum MDA and NO levels and SOD activity and plasma ET concentration, and contents of hydroxyproline and proteins in the vascular wall were determined.
RESULTCompared with the model group, the level of blood lipids did not significantly change, serum MDA and ET levels, and the contents of hydroxyproline and proteins in the vascular wall significantly decreased (P < 0.05), and SOD activity and NO level increased in the divided functional recipes (all P < 0.05).
CONCLUSIONThe divided functional recipes of DHZCP can inhibit development of atherosclerosis via a non-lowering lipid mechanisms, including anti-peroxidation of lipids, protection of endothelial function, and decrease of formation of extracellular matrix by reducing synthesis of collage and protein on the vascular wall. Among them, the divided functional recipe No. 1 exhibits the most obvious effect.

BACKGROUNDConnective tissue growth factor (CTGF) is a secreted protein containing several domains that mediate interactions with growth factors, integrins and extracellular matrix components. CTGF plays an important role in extracellular matrix production by its ability to mediate collagen deposition during wound healing. CTGF also induces neovascularization in vitro, suggesting a role in angiogenesis in vivo. We herein evaluated whether CTGF was required for extracellular matrix synthesis of meniscal fibrochondrocytes and/or angiogenesis during the repair of meniscal tears.
METHODSMeniscal fibrochondrocytes were isolated from the inner-1/2 of rabbit meniscus by trypsin collagenase treatment and further treated with 100 ng/ml CTGF in vitro. Characterization of fibrochondrocytes was identified by flow cytometry analyzing CD31, CD44, CD45 and CD105, and was further tested by type II collagen immunocytochemistry. Changes in gene expression of meniscal fibrochondrocytes were monitored by quantitative real-time polymerase chain reaction. Histological sections prepared from a 3-mm portion of a longitudinal tearing defect in the middle of the rabbit meniscus were subjected to fluorescence-immunohistochemistry analysis at 1, 4 and 10 weeks following surgical treatment with 1.5 µg of CTGF/fibrin-glue composites.
RESULTSQuantitative RT-PCR assay showed that types I and II collagen and vascular endothelial growth factor mRNA expression in the 100 ng/ml CTGF group were remarkably enhanced as compared to levels in the no-dose group at 14 days ((2.38 ± 0.63) fold, (2.96 ± 0.87) fold, (2.14 ± 0.56) fold, respectively). Likewise, fluorescence-immunohistochemical analysis revealed that in the group implanted with CTGF-fibrin glue, types I and II collagen, as well as the capillaries, completely filled the defect by 10 weeks, postoperatively. In contrast, only soft tissue repair occurred when PBS-fibrin glue was implanted.
CONCLUSIONSThese findings suggest that CTGF can significantly promote extracellular matrix deposition (types I and II collagen) within the meniscal avascular zone; CTGF can greatly heighten the expression of vascular endothelial growth factor activity simultaneously in vivo, further enhancing the repair of meniscal tears in the avascular zone.

OBJECTIVETo investigate the role and mechanism of Astragalus (AS) and saponins of Panax notoginseng (PNS) in treating type 2 diabetic macroangiopathy.
METHOD94 patients with type 2 diabetic macroangiopathy were divided into two groups randomly: group treated with Simvastatin and group treated with AS and PNS, compared with 40 healthy control subjects. Serum level of MMP-9 and lipid in patients and healthy subjects were measured before and after treatment.
RESULTThe serum levels of MMP-9, TG, TC, LDL-C, VLDL-C in patients with type 2 diabetic macroangiopathy were improved, while the levels of HDL-C were decreased. Like Simvastatin AS and PNS had the function of reducing MMP-9 and accommodating lipid metabolism.
CONCLUSIONBesides accommodating lipid metabolism, AS and PNS can also reduce the level of serum MMP-9 soas to treat type 2 diabetic macroangiopathy.
