ABSTRACT
ObjectiveTo observe the clinical efficacy and anti-inflammatory and anti-oxidant effect of modified Guipitang combined with Xuefu Zhuyutang in the treatment of mild cognitive impairment （MCI） after cerebral infarction with syndromes of heart and spleen deficiency and blood stasis blocking collateral. MethodA total of 114 eligible patients were randomly divided into a control group and an observation group，with 57 cases in each group. Patients in the control group were given red deer ginseng tablets （po），4 tablets/time，2 times/day. Patients in the observation group were given modified Guipitang combined with Xuefu Zhuyutang （po，1 dose/day）for continuous 8 weeks. This study compared the scores of montreal cognitive assessment （MoCA） scale，Rivermead behavioral memory test （RBMT），activities of daily living （ADL），trail making test B （TMT-B），neuropsychiatric inventory questionnaire （NPI） and scores of traditional Chinese medcine（TCM） syndrome with syndromes of heart and spleen deficiency and blood stasis blocking collateral before and after treatment. Then we further detected the levels of 8-hydroxydeoxyguanosine （8-OHDG），malondialdehyde （MDA），oxidized low density lipoprotein （ox-LDL），superoxide dismutase （SOD），homocysteine （Hcy），interleukin-8 （IL-8），C-reactive protein （CRP） and fibrinogen （FIB） levels before and after treatment. ResultThe total effective rate for the treatment of cognitive function impairment in the observation group was 92.98% （53/57），which was higher than 78.95% （45/57） in the control group （χ2＝4.653，P<0.05）. The recovery rate of cognitive function in the observation group was 54.39% （31/57），which was higher than 33.33% （19/57） in the control group （χ2＝5.130，P<0.05）. The MoCA，RBMT and ADL scores of the observation group were higher than those of the control group （P<0.01），and the TMT-B time of the former was shorter than that of the latter （P<0.01）. In addition， the observation group showed lower scores of TCM syndrome，NPI-1 and NPI-2 scores than the control group （P<0.01）. The SOD level of the observation group was higher than that of the control group （P<0.01），and the levels of 8-OHDG，ox-LDL，MDA，Hcy，IL-8，CRP and FIB were lower than those of the control group （P<0.01）. ConclusionModified Guipitang combined with Xuefu Zhuyutang can improve cognitive function in MCI patients after cerebral infarction with syndromes of heart and spleen deficiency and blood stasis blocking collateral， with anti-inflammatory and anti-oxidant effect， and yield superior efficacy than red deer ginseng tablets.
ABSTRACT
ObjectiveTo investigate the therapeutic effect of Xuebijing injection （XBJ） on sodium taurocholate （Na-Tc）-induced severe acute pancreatitis （SAP） in rats. MethodForty rats were randomly assigned into 5 groups： sham operation group， SAP model group， and low-， medium-， and high-dose （4， 8， 12 mL·kg·d-1， respectively） XBJ groups. SAP model was established by retrograde injection of Na-Tc （1 mL·kg-1） into the biliary and pancreatic ducts. XBJ was injected intraperitoneally 3 days before and 0.5 h after modeling. The ascitic fluid volume and the pancreas weight-to-body weight ratio were measured. The pathological changes of pancreatic tissue were observed via hematoxylin-eosin （HE） staining. The protein levels of formyl peptide receptor 1 （FPR1） and nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） in pancreatic tissue were detected by immunohistochemistry. Western blot was employed to determine the expression levels of NADH-ubiquinone oxidoreductase chains 1-6 （MT-ND1， MT-ND2， MT-ND3， MT-ND4， MT-ND5， and MT-ND6） in rat plasma. ResultCompared with sham operation group， the SAP model group showcased increased ascitic fluid volume and pancreas weight-to-body weight ratio （P<0.05）， serious lesions in pancreatic tissue， increased total pathological score （P<0.05）， and up-regulated protein levels of FPR1 and NLRP3 in pancreatic tissue （P<0.05）. The model group had lower MT-ND2 level （P<0.05） and higher MT-ND1， MT-ND3， and MT-ND6 levels in plasma （P<0.05） than the sham operation group， while MT-ND4 and MT-ND5 had no significant differences between the two groups. Compared with SAP model group， the XBJ treatment decreased ascitic fluid volume and pancreas weight-to-body weight ratio （P<0.01）， ameliorated pancreatic lesions， and down-regulated the protein levels of FPR1 and NLRP3 in pancreatic tissue （P<0.01）. The treatments， especially high-dose XBJ （P<0.01）， down-regulated the expression of MT-ND1 （P<0.01）， MT-ND3 （P<0.01）， MT-ND6 （P<0.01）， and MT-ND4 and did not change that of MT-ND5. ConclusionXBJ may antagonize partial mitochondrial N-formyl peptides and excessive inflammatory response mediated by FPR1/NLRP3 to treat SAP in rats.
ABSTRACT
ObjectiveTo explore the radiosensitization and underlying mechanism of Xuefu Zhuyutang on subcutaneous transplanted esophageal carcinoma. MethodThe subcutaneous xenograft model of human esophageal carcinoma ECA-109 in nude mice was induced and the model mice were divided into a model group， an irradiation group， a Xuefu Zhuyutang group， and a combination group， with six nude mice in each group. After the intervention， the transplanted tumors were removed and weighed， and the tumor inhibition rate of each group was calculated according to the formula. The protein expression of hypoxia-inducible factor-1α （HIF-1α） and vascular endothelial growth factor A （VEGFA） was detected by immunohistochemistry （IHC）. The protein expression of mammalian target of rapamycin （mTOR）， HIF-1α， VEGFA， and vascular endothelial growth factor receptor 2 （VEGFR2） in transplanted tumors was detected by Western blot. The mRNA expression of mTOR， HIF-1α， and VEGFA in transplanted tumors was detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the conditions in the model group， the tumor weight decreased in the irradiation group and the Xuefu Zhuyutang group （P<0.05）， as well as the combination group （P<0.01）. Compared with the irradiation group， the combination group showed decreased tumor weight （P<0.05）， with tumor inhibition rate of 57.37%. Compared with the model group， the irradiation group， the Xuefu Zhuyutang group， and the combination group showed decreased protein expression of VEGFR2， p-mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01） and reduced mRNA expression of mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01）. Compared with the irradiation group， the combination group showed down-regulated protein expression of VEGFR2， p-mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01） and reduced mRNA expression of mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01）. ConclusionXuefu Zhuyutang can inhibit the growth of transplanted esophageal carcinoma ECA-109 in nude mice and shows an obvious radiosensitization effect in combination with radiotherapy. The mechanism may be related to the inhibition of the mTOR/HIF-1α/VEGFA signaling pathway to improve the hypoxic state of tumors.
ABSTRACT
Objective:To compare the effect and mechanisms of modified Erchentang and Xuefu Zhuyutang on high-fat diet-induced apolipoprotein-E knockout (ApoE-/-) mice nonalcoholic fatty liver disease (NAFLD). Method:Ten C57/BL6J mice were taken as normal control group and fed with normal feed. Totally 30 ApoE-/- mice were fed with high-fat diet to establish a disease model for 4 weeks. After 4 weeks, the 30 ApoE-/- mice were divided into model group, Xuefu Zhuyutang group (hereinafter referred to as Huoxue group) and modified Erchentang group (hereinafter referred to as Huatan group) by random number table method, with 10 in each group. The normal group and the model group were intragastrically administered with normal saline. The drug-administered group was intragastrically administered at a dosage that was ten times of the adult dose, once a day, for 8 weeks. Serum and liver were collected after the end of the 12-week experiment. The serum lipid and liver function levels of each group were measured, and the liver pathological morphology was observed. Protein and mRNA expressions of liver inflammatory mediators interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), matrix metalloproteinase-9 (MMP-9), monocyte chemotactic factor-1 (MCP-1) were detected by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot. Result:The results of serum lipids and liver function showed that compared with the normal group, serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in the model group were significantly increased, while serum high-density lipoprotein (HDL) was significantly reduced (P<0.01). Compared with the model group, serum TG ，LDL and ALT were significantly decreased, HDL was significantly increased in the Huoxue group (P<0.05). The serum levels of TC, TG， LDL, AST and ALT in the Huatan group were significantly decreased，HDL was significantly increased (P<0.05，P<0.01), and TG was decreased. The mice serum HDL in the Huatan group was higher than that in the Huoxue group. The serum ALT in the Huoxue group was lower than that in the Huatan group. The pathological observation showed that compared with the normal group, hepatocytes in the model group had severe steatosis with many lipid droplet vacuoles, suggesting that the mouse NAFLD model was successful. Compared with the model group, each administration group alleviated hepatocyte steatosis, with no significant difference between the two administration groups. Western blot and Real-time PCR results showed that compared with the normal group, protein and mRNA expression levels of TNF-α, IL-1β, MCP-1, and MMP-9 in the model group were significantly increased (P<0.05，P<0.01). Compared with the model group, the Huoxue group significantly down-regulated the expressions of IL-1β, MCP-1 protein and MCP-1 mRNA(P<0.05，P<0.01). The Huatan group significantly reduced the expressions of IL-1β, TNF-α, MMP-9, MCP-1 protein, TNF-α and MMP-9 mRNA(P<0.05，P<0.01). Conclusion:Modified Erchentang and Xuefu Zhuyutang can alleviate the therapeutic effect of NAFLD mice to a certain extent, modified Erchentang has a better therapeutic effect.
