The lymphatic metastasis affects prognosis and survival of colorectal cancer seriously,and lymphangiogenesis plays an important role in the lymphatic metastasis. Many factors such as COX-2 and MMP-7 which are found in many researches recently can promote the expression of VEGF-C which can promote the lym-phangiogenesis by connecting with its receptor and activating the relevant signal pathway. At present,as these related factors of lymphangiogenesis are found in colorectal cancer,the process of lymphangiogenesis in colorec-tal cancer becomes more clear,but the exact mechanism of these factors needs to be researched in future.

Bone-modifying agents (BMA) is a series drugs to alleviate the pain,pathological fractures,spinal cord compression,hypercalcemia,bone-related events which induced by bone metastases.Bisphosphonate drugs and denosumab are two dominant kinds of BMA at present.It has been proved that BMA is used in bone metastases patients with bone destruction,as adjuvant therapy for chemotherapy and radiotherapy,which can significantly improve the efficacy and prolong the survival of patients.In addition,some traditional Chinese medcine can effectively relieve a series of related symptoms caused by bone metastases and improve prognosis.Choosing right medication in clinical work can maximize the reduction of pain caused by bonerelated events and improve the quality of life of patients.

Objective: To observe the effects of Danggui Shaoyao powder (DSP) on hepatic lipid metabolism and further explore its mechanism of action by peroxisome proliferator-activated receptor (PPARγ)-liver X receptor (LXRα)-adenosine triphosphate (ATP)-binding cassette transporter A1 (ABCA1) pathway regulation. Methods: Eight C57BL/6J male mice were selected as the control group, and 24 ApoE−/− male mice were randomly divided into the atherosclerosis model (AS) group, atorvastatin calcium (AC) group, and DSP group (n = 8 each group). To establish an AS model, ApoE−/− mice were fed a high-fat diet for 16 weeks. Pathologic changes in the aortic vasculature and liver were identified using Oil Red O staining. Triglyceride (TG), cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were determined in the livers using a single-reagent GPO-PAP method. Fluorescence quantitative polymerase chain reaction and western blot were used to observe and evaluate the mRNA and protein expression of the PPARγ-LXRα-ABCA1 intermediates in the liver. Results: After 16 weeks of a high-fat diet, ApoE−/− mice showed more Oil Red O staining in the aorta and liver compared to the CONT group. Compared to the AS group, the DSP and AC treatment reduced aortic plaque and hepatic lipid deposition to varying degrees. Furthermore, DSP significantly reduced the hepatic lipid area in ApoE−/− mice (P < .001) and decreased the levels of TG, TC, and LDL-C in liver (P < .001, P = .027, P < .001, respectively). DSP also significantly increased the levels of PPARγ, LXRα, ABCA1, and ABCG1 mRNA expression, as well as the PPARγ, LXRα, ABCA1, and ABCG1 protein expression in liver. Conclusion DSP improved hepatic lipid metabolism via PPARγ-LXRα-ABCA1 pathway modulation for AS treatment.
