Methods：Rat models with expansionary myocardial disease were established by Pituitrin and Furazolidone. Experimental rats were divided into the contrast group, the myocardial scathe group （MS group）, the myocardial scathe and Fufang Dansben pill group （ MS ＋ FD group） and the myocardial scathe and fluvastatin group （ MS ＋ FT group）. The ratio of CD34^＋ cells was examined at the 1^st, 3^nl and 6^th weekend. Index of heart structure and function including LVESD, LVEDD. LYEF, LVEDP and dp/dtmax were evaluated at the 6^th weekend. The HW/BW index was calculated. Results：In the MS group, the index of HW/BW, LVESD, LVEDD and LVEDP were obviously increased （P 〈 0.01 ） and index of dp/ dtmax and LVEF were obviously decreased （P 〈 0.05 ）. The ratio of CD34^＋ cells was significantly improved at the 1^at weekend and then reduced slowly with no difference from that of the contrast group at the 6th weekend. Compared the MS ＋ FD group and the MS ＋ FT group with the MS group, the index of HW/BW, LYESD, LYEDD and LYEDP of were signifi cantly decreased （ P 〈 0.05 ） and index of dp/dtmax and LVEF were increased （P 〈 0.01 ）. The ratio of CD34^＋ cells was significantly higher at the 1^st, 3^nl and 6^th weekend, but had no statistic meaning at 3^nl and 6^th weekend （P 〉 0.05 ）. Conclusion：Pituitrin and Furazolidone can be used to establish rat models with expansionary myocardial disease. There has bone marrow stem mobilization during the early period of myocardial scathe. Fufang Danshen pill has effect on improving bone marrow stem mobilization, lightening the expansionary degree of heart and protecting the heart function.

METHODS: LPS was continuously infused through the jugular artery of male Wistar rats at the dose of 2 mg/kg per hour. Changes in mesenteric microcirculation,such as diameters of arterioles and venules,velocity of RBCs in venules,leukocyte rolling,adhesion and emigration,free radicals released from post-capillary venules,FITC- albumin leakage and mast cell degranulation,were observed through an inverted intravital microscope assisted with CCD camera and SIT camera. Meanwhile,the expression of adhesion molecules CD11b/CD18 and the production of free radical in neutrophils,and the expression of intercellular adhesion molecule 1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) were quantified by flow cytometry (FACS) in vitro. RESULTS: The continuous infusion with LPS resulted in a number of responses in microcirculation,including a significant increase in the positive region of venulestained with Monastral blue B,rolling and adhesion of leukocytes,production of oxygen radical in venular wall,albumin efflux and enhanced mast cell degranulation in vivo,all of which,except for the leukocyte rolling,were attenuated by the treatment with compound Danshen injection. Experiments performed in vitro further revealed that the expression of CD11b/CD18 and the production of oxygen free radical in neutrophils,and the expression of ICAM-1 in HUVECs were increased by exposure to LPS,and they were attenuated by compound Danshen injection. CONCLUSION: These results suggest that compound Danshen injection is an efficient drug with multi-targeting potential for improving the microcirculatory disturbance.展开更多

In the clinical study, we randomly divided 24 subjects with hypercholesterolemia into two groups （the control group and the Danshen-treated group）. At the end of two weeks of treatment, the EPC cellular functions of both groups were tested. The results indicated that, compared to the control group, EPCs in the Danshen-treated group showed significantly better cellular functions, which was manifested in the cloning number, the proliferation capacity, the number of EPC adhesions, and cell migration. In the subsequent in-vitro experiments, EPCs were treated with vehicle, oxidized low-density lipoprotein （Ox-LDL, 100 pg/ml）, or Ox-LDL （100 pg/ml） plus different concentrations of Danshen （Danshensu 2, 10, or 50 pg/ml, respectively） for 24 h. The results showed that Danshen treatments can prevent the detrimental effects of Ox-LDL on EPC cellular functions measured by proliferation capacity （0.24±0.08, 0.37±0.11, 0.30±0.04 vs. 0.13±0.02, P〈0.05, P〈0.01, and P〈0.01, respectively）, and adhesion ability （63.00_±11.60, 70.00±10.80, 85.50±11.41 vs. 40.50±6.85, all P〈0.01）. Compared to the group treated with Ox-LDL alone, Danshen treatment significantly decreased the lipid peroxidation end product malondialdehyde （MDA） [（4.34±0.54）, （3.98±0.47）, （3.46±0.31） vs. （5.57-±0.64） nmol/ml, all P〈0.01], increased the production of superoxide dismutase （SOD） [（29.74±0.71）, （31.09±0.83）, （30.41±0.65） vs. （14.76±3.99） U/ml, all P〈0.01], and lowered the expression of interleukin-6 （IL-6） [（24.62±7.69）, （27.04±3.14）, （33.38±18.86） vs. （230.67±33.53） pg/ml, all P〈0.01] and tumor necrosis factor-α （TNF-α） [（41.72±6.10）, （17.02±6.82）, （3.73±2.26） vs. （228.71±41.53） pg/ml, all P〈0.01] in Ox-LDL treated EPCs. These results suggest that Danshen may exert a protective effect through its antioxidant and anti-inflammatory features.展开更多

The cell model was treated with donepezil or compound Danshen tablets after culture for 72 hours. Reverse transcription-PCR showed that the mRNA expression of amyloid protein precursor decreased in all groups following culture for 24 hours, and that there was no significant difference in the amount of decrease between donepezil and compound Danshen tablets. Our results suggest that compound Danshen tablets can reduce expression of the mRNA for amyloid protein precursor in a transgenic cell model of Alzheimer＇s disease, with similar effects to donepezil.展开更多

In the present study, the effect of Danshen on cisplatin-induced renal dysfunction was investigated in a mouse model. Danshen was administered to mice at a dose of 3 g/kg 4 days before and 3 days after cisplatin treatment. A single intraperitoneal injection of 20 mg/kg cisplatin was used to induce nephrotoxicity. The mice were sacrificed 72 h after cisplatin intoxication. Biochemical parameters including serum creatinine and blood urea nitrogen were analyzed. Histopathological changes of kidney tissues were detected using HE staining. Antioxidant enzymes（GSH-Px and SOD） and peroxidative product（MDA） were detected. Protein expressions of Nrf2 and its target genes including HO-1 and NQO1 were measured by Western blotting. The results showed that pretreatment with Danshen significantly reduced serum creatinine and blood urea nitrogen in the cisplatin-treated mice. Histopathological examination showed that Danshen mitigated the renal damage induced by cisplatin. Moreover, Danshen restored the activities of antioxidant enzymes（GSH-Px and SOD） and normalized the MDA contents in renal tissues. Western blotting revealed that Danshen enhanced the expressions of Nrf2 and its target genes in cisplatin-exposed mice. It was suggested that Danshen protects against the cisplatin-induced renal impairment in the mice, which is potentially associated with the upregulation of Nrf2-mediated signaling pathway.展开更多

Data from Ⅰ-Ⅳ clinical drug trials, hospital information systems(HIS), and spontaneous reporting systems(SRS) were also analyzed.RESULTS: The effective components of salvianolic acid salt content reached almost 100%, and the magnesium lithospermate B content reached morethan 80%. The median lethal dose(LD50) calculated by the Bliss method was 1.49 g/kg, with 95%confidence intervals of 1.29-1.72 g/kg. Long-term tests on Beagle dogs indicated that doses of less than 80 mg/kg were safe and doses of 320 mg/kg were toxic. Adverse drug reactions(ADRs) included digestive disorders; drug-induced erythrocyte deformation in lung, liver, spleen, kidney, bone marrow, intestinal mucosa, lymph nodes, and other tissues; megakaryocytes in lung, liver, and spleen resulting from mild hemolysis; and mild hyperplasia in bone marrow hematopoietic tissue. Other studies indicated no irritative effect of the injection on local tissues and blood vessels, and no allergic reactions, erythrocyte coagulation, or hemolysis. SRS data showed that the most common ADRs were headache, head distention, dizziness, facial flushing, skin itching, thrombocytopenia, and the reversibility of elevated Aspartate transaminase. HIS data indicated no damage to renal function from using depside salt injection made from Danshen(Radix Salviae Miltiorrhizae) at a dosage higher than the recommended dose.CONCLUSION: This study analyzes the clinical characteristics of ADRs from depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),and discusses the factors influencing such reactions. It provides scientific reference and recommendations for clinically safe medication of the Danshen injection.展开更多

However, litt...Danshen, the dried root of Salvia miltiorrhiza Bunge（Lamiaceae）, is one of the traditional Chinese medicines（TCMs） most commonly used for the treatment of cardiovascular and cerebrovascular diseases. However, little is known about the chemical and metabolic profiles of danshen in vitro or in vivo. In particular, more information is needed in relation to the 50% ethanol extracts usually used in danshen formulations such as Fufang Xueshuantong Capsules and Fufang Danshen tablets. High-performance liquid chromatography coupled with a linear ion trapOrbitrap mass spectrometer（HPLC-LTQ-Orbitrap） provides a sensitive and accurate method for analyzing the composition of samples. This method was used to determine the in vitro and in vivo chemical and metabolic profiles of danshen. Sixty-nine components of danshen extract and 118 components of danshen in rat plasma, urine, feces, and bile were unambiguously or tentatively identified. These results not only revealed the material composition of danshen, but also provided a comprehensive research approach for the identification of multi-constituents in TCMs.展开更多

Methods： 30 Wister rats were randomly divided into control group, asthma group and Danshen Injection treated group. Bronchoalveolar lavage fluids （BALF） were collected, and cytology studies were conducted. Lung tissues were obtained and pathologic analyses were done with hematoxylin and eosin stain （HE）. Flow cytometry was used to detect the CD4^＋CD25^＋ Tr ratio in peripheral blood mononuclear cells （PBMCs）. Results： Total cell, the percentage of lymphocytes, neutrophils and eosinophils （Eos） in BALF of Danshen Injection-treated group were lower than that in asthma group （P〈0.05, P〈0.01）. Compared with asthma group, less infiltration of inflammatory cells in lung tissues was observed in Danshen Injection-treated group. CD4^＋CD25^＋ Tr of asthma group was lower than that of control and Danshen Injection treated group （P〈0.05）. Conclusion： Danshen Injection can suppress airway inflammation of asthmatic rats, probably by increasing the number of CD4^＋CD25^＋ Tr.展开更多

Methods: Adult male SD rats were randomly divided into 3 groups: sham (group A), I/R (group B), and I/R plus CDDP (group C). Retinal ischemia/reperfusion injury (RIRI) was introduced by increasing the intraocular pressure (IOP) to 110 mmHg for 60 min via cannulation into the anterior chamber. Right after the insult, CDDP was administered intragastrically (450 mg/kg/d) for 7 days. The levels of malondialdehyde (MDA), the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in the retinal tissues were determined on d1 and d7 after the ischemic insult. Results: Following ischemia, the MDA levels in group B and group C were significantly higher than those in group A (p < 0.01). CDDP significantly lowered MDA levels in group C when compared with group B (p < 0.01). The activities of SOD, GSH-Px and CAT were higher in group A than in group B and group C (p < 0.01). CDDP could increase the activities of SOD, GSH-Px and CAT remarkably in group C when compared with group B (p < 0.01). Conclusion: CDDP can protect the retina from I/R injury through reducing oxidative stress, and thus may be a promising method for the treatment of ischemic retinal disorders.展开更多

文摘Danshen, the dried root or rhizome of Salvia miltiorrhiza Bge., is a traditional and folk medicine in Asian countries, especially in China and Japan. In this review, we summarized the recent researches of Danshen in traditional uses and preparations, chemical constituents, pharmacological activities and side effects. A total of 201 compounds from Danshen have been reported, including lipophilic diterpenoids, water-soluble phenolic acids, and other constituents, which have showed various pharmacological activities, such as anti-inflammation, anti-oxidation, anti-tumor, anti-atherogenesis, and anti-diabetes. This article intends to provide novel insight information for further development of Danshen, which could be of great value to its improvement of utilization.
文摘AIM: To investigate the effect of compound Danshen injection on lipopolysaccharide (LPS)-induced rat mesenteric microcirculatory dysfunctions and the underlying possible mechanism by an inverted intravital microscope and high-speed video camera system. METHODS: LPS was continuously infused through the jugular artery of male Wistar rats at the dose of 2 mg/kg per hour. Changes in mesenteric microcirculation,such as diameters of arterioles and venules,velocity of RBCs in venules,leukocyte rolling,adhesion and emigration,free radicals released from post-capillary venules,FITC- albumin leakage and mast cell degranulation,were observed through an inverted intravital microscope assisted with CCD camera and SIT camera. Meanwhile,the expression of adhesion molecules CD11b/CD18 and the production of free radical in neutrophils,and the expression of intercellular adhesion molecule 1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) were quantified by flow cytometry (FACS) in vitro. RESULTS: The continuous infusion with LPS resulted in a number of responses in microcirculation,including a significant increase in the positive region of venulestained with Monastral blue B,rolling and adhesion of leukocytes,production of oxygen radical in venular wall,albumin efflux and enhanced mast cell degranulation in vivo,all of which,except for the leukocyte rolling,were attenuated by the treatment with compound Danshen injection. Experiments performed in vitro further revealed that the expression of CD11b/CD18 and the production of oxygen free radical in neutrophils,and the expression of ICAM-1 in HUVECs were increased by exposure to LPS,and they were attenuated by compound Danshen injection. CONCLUSION: These results suggest that compound Danshen injection is an efficient drug with multi-targeting potential for improving the microcirculatory disturbance.

文摘In this study, we examined the protective effects of Danshen both on endothelial progenitor cells （EPCs） in patients with hypercholesterolemia and on in-vitro EPCs of healthy volunteers. In the clinical study, we randomly divided 24 subjects with hypercholesterolemia into two groups （the control group and the Danshen-treated group）. At the end of two weeks of treatment, the EPC cellular functions of both groups were tested. The results indicated that, compared to the control group, EPCs in the Danshen-treated group showed significantly better cellular functions, which was manifested in the cloning number, the proliferation capacity, the number of EPC adhesions, and cell migration. In the subsequent in-vitro experiments, EPCs were treated with vehicle, oxidized low-density lipoprotein （Ox-LDL, 100 pg/ml）, or Ox-LDL （100 pg/ml） plus different concentrations of Danshen （Danshensu 2, 10, or 50 pg/ml, respectively） for 24 h. The results showed that Danshen treatments can prevent the detrimental effects of Ox-LDL on EPC cellular functions measured by proliferation capacity （0.24±0.08, 0.37±0.11, 0.30±0.04 vs. 0.13±0.02, P〈0.05, P〈0.01, and P〈0.01, respectively）, and adhesion ability （63.00_±11.60, 70.00±10.80, 85.50±11.41 vs. 40.50±6.85, all P〈0.01）. Compared to the group treated with Ox-LDL alone, Danshen treatment significantly decreased the lipid peroxidation end product malondialdehyde （MDA） [（4.34±0.54）, （3.98±0.47）, （3.46±0.31） vs. （5.57-±0.64） nmol/ml, all P〈0.01], increased the production of superoxide dismutase （SOD） [（29.74±0.71）, （31.09±0.83）, （30.41±0.65） vs. （14.76±3.99） U/ml, all P〈0.01], and lowered the expression of interleukin-6 （IL-6） [（24.62±7.69）, （27.04±3.14）, （33.38±18.86） vs. （230.67±33.53） pg/ml, all P〈0.01] and tumor necrosis factor-α （TNF-α） [（41.72±6.10）, （17.02±6.82）, （3.73±2.26） vs. （228.71±41.53） pg/ml, all P〈0.01] in Ox-LDL treated EPCs. These results suggest that Danshen may exert a protective effect through its antioxidant and anti-inflammatory features.

文摘After gene mutation, the pcDNA3.1/APP595/596 plasmid was transfected into HEK293 cells to establish a cell model of Alzheimer＇s disease. The cell model was treated with donepezil or compound Danshen tablets after culture for 72 hours. Reverse transcription-PCR showed that the mRNA expression of amyloid protein precursor decreased in all groups following culture for 24 hours, and that there was no significant difference in the amount of decrease between donepezil and compound Danshen tablets. Our results suggest that compound Danshen tablets can reduce expression of the mRNA for amyloid protein precursor in a transgenic cell model of Alzheimer＇s disease, with similar effects to donepezil.

文摘Danshen, an efficacious agent for cardiovascular diseases, has been found to play an essential role in kidney injury. In the present study, the effect of Danshen on cisplatin-induced renal dysfunction was investigated in a mouse model. Danshen was administered to mice at a dose of 3 g/kg 4 days before and 3 days after cisplatin treatment. A single intraperitoneal injection of 20 mg/kg cisplatin was used to induce nephrotoxicity. The mice were sacrificed 72 h after cisplatin intoxication. Biochemical parameters including serum creatinine and blood urea nitrogen were analyzed. Histopathological changes of kidney tissues were detected using HE staining. Antioxidant enzymes（GSH-Px and SOD） and peroxidative product（MDA） were detected. Protein expressions of Nrf2 and its target genes including HO-1 and NQO1 were measured by Western blotting. The results showed that pretreatment with Danshen significantly reduced serum creatinine and blood urea nitrogen in the cisplatin-treated mice. Histopathological examination showed that Danshen mitigated the renal damage induced by cisplatin. Moreover, Danshen restored the activities of antioxidant enzymes（GSH-Px and SOD） and normalized the MDA contents in renal tissues. Western blotting revealed that Danshen enhanced the expressions of Nrf2 and its target genes in cisplatin-exposed mice. It was suggested that Danshen protects against the cisplatin-induced renal impairment in the mice, which is potentially associated with the upregulation of Nrf2-mediated signaling pathway.

Data from Ⅰ-Ⅳ clinical drug trials, hospital information systems(HIS), and spontaneous reporting systems(SRS) were also analyzed.RESULTS: The effective components of salvianolic acid salt content reached almost 100%, and the magnesium lithospermate B content reached morethan 80%. The median lethal dose(LD50) calculated by the Bliss method was 1.49 g/kg, with 95%confidence intervals of 1.29-1.72 g/kg. Long-term tests on Beagle dogs indicated that doses of less than 80 mg/kg were safe and doses of 320 mg/kg were toxic. Adverse drug reactions(ADRs) included digestive disorders; drug-induced erythrocyte deformation in lung, liver, spleen, kidney, bone marrow, intestinal mucosa, lymph nodes, and other tissues; megakaryocytes in lung, liver, and spleen resulting from mild hemolysis; and mild hyperplasia in bone marrow hematopoietic tissue. Other studies indicated no irritative effect of the injection on local tissues and blood vessels, and no allergic reactions, erythrocyte coagulation, or hemolysis. SRS data showed that the most common ADRs were headache, head distention, dizziness, facial flushing, skin itching, thrombocytopenia, and the reversibility of elevated Aspartate transaminase. HIS data indicated no damage to renal function from using depside salt injection made from Danshen(Radix Salviae Miltiorrhizae) at a dosage higher than the recommended dose.CONCLUSION: This study analyzes the clinical characteristics of ADRs from depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),and discusses the factors influencing such reactions. It provides scientific reference and recommendations for clinically safe medication of the Danshen injection.

文摘Danshen, the dried root of Salvia miltiorrhiza Bunge（Lamiaceae）, is one of the traditional Chinese medicines（TCMs） most commonly used for the treatment of cardiovascular and cerebrovascular diseases. However, little is known about the chemical and metabolic profiles of danshen in vitro or in vivo. In particular, more information is needed in relation to the 50% ethanol extracts usually used in danshen formulations such as Fufang Xueshuantong Capsules and Fufang Danshen tablets. High-performance liquid chromatography coupled with a linear ion trapOrbitrap mass spectrometer（HPLC-LTQ-Orbitrap） provides a sensitive and accurate method for analyzing the composition of samples. This method was used to determine the in vitro and in vivo chemical and metabolic profiles of danshen. Sixty-nine components of danshen extract and 118 components of danshen in rat plasma, urine, feces, and bile were unambiguously or tentatively identified. These results not only revealed the material composition of danshen, but also provided a comprehensive research approach for the identification of multi-constituents in TCMs.

文摘Objective: To investigate the effect of Compound Danshen Dripping Pills (CDDP) on oxidative stress after ischemia/reperfusion (I/R) injury in the rat retina. Methods: Adult male SD rats were randomly divided into 3 groups: sham (group A), I/R (group B), and I/R plus CDDP (group C). Retinal ischemia/reperfusion injury (RIRI) was introduced by increasing the intraocular pressure (IOP) to 110 mmHg for 60 min via cannulation into the anterior chamber. Right after the insult, CDDP was administered intragastrically (450 mg/kg/d) for 7 days. The levels of malondialdehyde (MDA), the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in the retinal tissues were determined on d1 and d7 after the ischemic insult. Results: Following ischemia, the MDA levels in group B and group C were significantly higher than those in group A (p < 0.01). CDDP significantly lowered MDA levels in group C when compared with group B (p < 0.01). The activities of SOD, GSH-Px and CAT were higher in group A than in group B and group C (p < 0.01). CDDP could increase the activities of SOD, GSH-Px and CAT remarkably in group C when compared with group B (p < 0.01).
