Effectiveness and safety of Danshen injections in treatment of cardiac failure: a network meta-analysis.

Objective: The purpose of this network meta-analysis (NMA) was to compare the therapeutic effects of various Danshen (Salvia miltiorrhiza Bunge [Lamiaceae; Salviae miltiorrhizae radix et rhizoma]) injections on heart failure to determine the optimal Danshen injection combined with conventional treatment. Methods: 8 databases were searched from the inception of these databases to May 2023 to collect randomized controlled trials (RCTs) on the effectiveness and safety of Danshen injections in the treatment of heart failure. This NMA was performed using Stata 16.0 software and R 4.1.3 software. Results: A total of 24 RCTs involving 2,186 subjects were included. The intervention group received Danshen injections plus conventional treatment, involving the following 7 Danshen injections. The results of the NMA showed that Compound Danshen injection + Common (SUCRA: 79.6%) and Sodium tanshinone ⅡA sulfonate injection + Common (SUCRA: 78.0%) exhibited higher total effective rates. Sodium tanshinone ⅡA sulfonate injection + Common (SUCRA: 94.3%) and Danshen injection + Common (SUCRA: 68.2%) were superior to other traditional Chinese medicines in improving left ventricular ejection fraction (LVEF). Danshen injection + Common (SUCRA: 99.9%) and Shenxiong glucose injection + Common (SUCRA: 77.2%) were the most effective in reducing brain natriuretic peptide (BNP). In addition, compared with conventional treatment, all Danshen injections did not increase the risk of adverse reactions. Conclusion: Current evidence shows that all seven Danshen injections are effective for heart failure. Due to the limited quantity and quality of the included studies, our findings need to be verified by more high-quality studies.

Network Meta-analysis of Chinese medicine injections in treatment of rheumatoid arthritis

This study aims to systematically evaluate the efficacy and safety of Chinese medicine injections in the treatment of rheumatoid arthritis. Specifically, randomized controlled trial(RCT) in the treatment of rheumatoid arthritis with Chinese medicine injections was retrieved from PubMed, EMbase, Cochrane Library, Web of Science, Wanfang, CNKI, VIP, and SinoMed(from inception to February 16, 2022).

The network Meta-analysis showcased the following trends.(1) As for improving total clinical effective rate, the surface under the cumulative ranking curve(SUCRA) followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Gugua Extract Injection > combined with Compound Danshen Injection > combined with Danshen Chuanxiongqin Injection > combined with Honghua Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Lugua Polypeptide Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Dengzhan Xixin Injection.(2) As for improving erythrocyte sedimentation rate(ESR), SUCRA followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Shuxuetong Injection > combined with Honghua Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Gugua Extract Injection > combined with Danhong Injection > combined with Lugua Polypeptide Injection > combined with Dengzhan Xixin Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Danshen Chuanxiongqin Injection > combined with Zhengqing Fengtongning Injection.(3) As for improving rheumatoid factor(RF), SUCRA followed the order of conventional treatment of western medicine combined with Lugua Polypeptide Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Gugua Extract Injection > combined with Danshen Chuanxiongqin Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Dengzhan Xixin Injection.(4) As for improving C-reactive protein(CRP), SUCRA followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Honghua Injection > combined with Danshen Chuanxiongqin Injection > combined with Dengzhan Xixin Injection > combined with Gugua Extract Injection > combined with Lugua Polypeptide Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection.(5) As for alleviating morning stiffness, SUCRA followed the order of conventional treatment of western medicine combined with Shuxuetong Injection > combined with Lugua Polypeptide Injection > combined with Dengzhan Xixin Injection > combined with Xuebijing Injection > combined with Gugua Extract Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Honghua Injection.(6) As for improving disease activity score(DAS28), SUCRA followed the order of conventional treatment of western medicine combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection > combined with Zhengqing Fengtongning Injection > combined with Honghua Injection > combined with Gugua Extract Injection > combined with Dengzhan Xixin Injection. The experimental groups had lower incidence of adverse reactions than the control group. The results of network Meta-analysis suggest that on the combination of conventional treatment of western medicine with Chinese medicine injections can improve the efficacy on rheumatoid arthritis. However, in view of the great differences in the quality and number of studies included for different therapies, the SUCRA of Chinese medicine injections need to be further verified with high-quality multi-center, large-sample, randomized double-blind trials.

Effects of Compound Danshen Injection Combined with Magnesium Sulfate on Pregnancy-Induced Hypertension Syndrome under the Guidance of Empirical Mode Decomposition Algorithm-Based Ultrasound Image.

Objective The study focused on the separation effects of ultrasound blood flow signal detection, based on empirical mode decomposition (EMD) algorithm, and the clinical efficacy of Compound Danshen injection and magnesium sulfate in the treatment of pregnancy-induced hypertension (PIH) syndrome. Methods The empirical mode decomposition (EMD) algorithm was optimized first and compared with other algorithms for the accuracy and stability in separation of blood flow signals. 80 patients with PIH syndrome undergoing ultrasound examination were selected as the research subjects and randomly divided into control group and observation group according to the actual treatment methods. 40 cases in the observation group were treated with Compound Danshen injection + magnesium sulfate, and 40 cases in the control group were treated with magnesium sulfate. After the treatment, the clinical indicators of the two groups of patients were analyzed. Results The accuracy and stability in separating blood flow signal of the optimized EMD algorithm were better than those of other algorithms. After treatment, the total effective rate and blood pressure control of the observation group were significantly better than those of the control group, and the incidence of adverse maternal and infant outcomes was significantly lower than that of the control group. After treatment, the endothelin-1 (ET-1), C-reactive protein (CRP), and homocysteine (Hcy) indexes of the two groups of patients decreased significantly, and the decrease level of the observation group was significantly greater than that of the control group (P < 0.05). The prothrombin time (PT), fibrinogen (FIB), activated partial thromboplastin time (APTT), and plasma thrombin time (TT) levels of the two groups after treatment were better than those before treatment, and the observation group was better than the control group (P < 0.05). Conclusion The optimized EMD algorithm is of great value for the separation of ultrasound blood flow signals. For patients with PIH syndrome, Compound Danshen injection combined with magnesium sulfate can be used as a treatment plan, which can improve maternal and infant outcomes; control blood pressure; reduce 24 h urine protein and serum ET-1, Hcy, and CRP levels; and improve coagulation function. It is worthy of promotion.

Systematic review of efficacy and safety of Compound Danshen Injection combined with Western medicine in treatment of vascular dementia

To evaluate the efficacy and safety of Compound Danshen Injection combined with Western medicine in the treatment of vascular dementia. Databases of Cochrane Library, PubMed, EMbase, CNKI, SinoMed, VIP, Wanfang Data were electronically retrieved for collecting randomized controlled trial(RCT)about vascular dementia treated with Western medicine alone or combined with Compound Danshen Injection from the year of database establishment to January 2020. Two researchers independently screened out li-teratures, extracted data, and evaluated the risk of bias for inclusion in the study. Meta-analysis was conducted using RevMan 5.3 software. A total of 5 RCTs were included, involving 588 patients, with 299 in treatment group and 289 in control group. Meta-analysis results showed that compared with Western medicine alone, Compound Danshen Injection combined with Western medicine was better in the effective rate(RR=1.23,95%CI[1.14,1.33],P&lt;0.000 01), MMSE score(MD=3.54,95%CI[3.01,4.06],P&lt;0.000 01), ADL score(MD=11.49,95%CI[8.05,14.93],P&lt;0.000 01), the level of CRP(MD=-0.72,95%CI[-1.25,-0.20],P=0.007) and the level of IL-6(MD=-7.64,95%CI[-9.65,-5.63],P&lt;0.000 01). Adverse reactions mainly included rash and skin prick, which did not affect the treatment effect. Based on the findings, the combination of Compound Danshen Injection in the treatment of vascular dementia could improve the effective rates, relieve the mental state damage and improve the daily living ability, with mild adverse reactions and a low incidence. However, due to the low quality of the included literatures, high-quality and large-scale randomized controlled trials are needed for further verification.

Effectiveness and safety of Compound Danshen injection as treatment for pregnancy-induced hypertension: A metaanalysis

Purpose: To systematically evaluate the effectiveness and safety of Compound Danshen injection in patients with pregnancy-induced hypertension (PIH).Methods: PubMed, Embase, Cochrane Library, Chinese biomedical literature database (CBM), VIP (xiAn), China National Knowledge Infrastructure (CNKI) and Wan Fang databases were searched up to March 20, 2018, for all randomized controlled trials (RCTs) on the use of Compound Danshen injection in patients with PIH. Data were extracted from included studies after assessing the quality of literature. Revman 5.3 software was used for statistical analysis．Results: A total of 18 RCTs involving 1735 patients were included. The results of meta-analysis indicated that the study group was superior to the control group in clinical effectiveness (RR = 1.15, 95 % CI: 1.02 - 1.30); intrauterine fetal distress (RR = 0.26, 95 % CI: 0.09 - 0.70); cesarean section (RR = 0.72, 95 % CI: 0.58 - 0.90), and neonatal asphyxia (RR = 0.23, 95 % CI: 0.11 - 0.48). There were no statistical differences in fetal heart rate abnormalities (RR = 0.58, 95 %, CI: 0.33 - 1.02, p &gt; 0.05) and postpartum hemorrhage (RR = 0.86, 95 % CI: 0.53 - 1.42) between the two groups.Conclusion: Treatment of PIH with Compound Danshen injection (alone or in combination) is superior to the use of conventional western medical treatment in safety and effectiveness. However, higher quality clinical studies are needed to confirm these results because most trials included in this study were of low quality.Keywords: Pregnancy-induced hypertension (PIH), Compound Danshen injection, Meta-analysis

Effects of compound Danshen injection combined with magnesium sulfate on serum MPO and hs-CRP in patients with severe preeclampsia.

Effects of compound Danshen injection combined with magnesium sulfate on serum myeloperoxidase (MPO) and hypersensitive C-reactive protein (hs-CRP) in patients with severe preeclampsia (PE) were investigated. Five hundred patients with severe PE were randomly divided into early-onset observation, early-onset control, late-onset observation and late-onset control groups. Control group was treated with magnesium sulfate, while patients in observation group were treated with magnesium sulfate combined with compound Danshen injection. Serum levels of MPO and hs-CRP were measured by enzyme-linked immunosorbent assay (ELISA) and turbidimetric assay. The effects of compound Danshen injection combined with magnesium sulfate on the above indexes were observed. Serum levels of MPO and hs-CRP significantly decreased in early-onset observation, late-onset observation, early-onset control and late-onset control groups after treatment (p<0.05). After treatment, levels of MPO and hs-CRP were significantly lower in early-onset observation group than in early-onset control group (p<0.05), and levels of MPO and hs-CRP were also significantly lower in late-onset observation group than in late-onset control group (p<0.05). Total effective rate of early-onset observation group and late-onset observation group were higher than that of early-onset control group and late-onset control group. Compound Danshen injection combined with magnesium sulfate achieved better treatment outcomes in the treatment of severe PE than magnesium sulfate alone. The combined treatment can effectively reduce the serum levels of MPO and hs-CRP.

Different network pharmacology mechanisms of Danshen-based Fangjis in the treatment of stable angina.

Danshen (Salvia miltiorrhiza) preparations such as Danhong injection, Danshen injection, Salvianolate injection, compound Danshen injection and Sodium Tanshinone IIA Sulfonate (STS) injection are widely used in China to treat stable angina (angina pectoris) caused by coronary heart disease. In this study we compared the network pharmacological mechanisms of the 5 Danshen preparations. Following a literature search performed in PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) database, China Biology Medicine (CBM) database, China Conference Paper Database, Wanfang Database, VIP Database and Conference Proceedings Citation Index (through January 2015), 444 randomized controlled trial publications detailing the use of the 5 Danshen-based injections for treating stable angina were identified, and their combined data were analyzed using a network meta-analysis. All of the 5 Danshen-based preparations were effective in treating stable angina with clinical improvement rates of 72.4%-91.6% and electrocardiogram (ECG) improvement rates of 54.5%-71.6%. According to both clinical improvement and ECG improvement, the 5 Danshen-based preparations were ranked as follows: Danhong injection > Salvianolate injection > STS injection > compound Danshen injection > Danshen injection. There were no significant differences among the safety profiles of the 5 Danshen preparations. The meta-analysis results were further examined using a network pharmacology approach and functional enrichment analysis, which revealed that Danshen and Danhong injections affected 4 and 15 signaling pathways, respectively, and that the 4 signaling pathways affected by Danshen were a subset of those influenced by Danhong. Therefore, Danhong injection affected some unique signaling pathways that might regulate lipoprotein metabolism, oxidation, and inflammation, and protect vascular endothelia, reflecting the multi-component and multi-target characteristics of this traditional formula and its strengths in treating complex diseases.

Observation of the efficacy of Toutongning capsule combined with nimodipine in the treatment of 76 patients with primary vascular headache

Objective To explore the clinical efficacy of Toutongning capsule combined with nimodipine in the treatment of 76 patients with primary vascular headache. Methods 76 patients with primary vascular headache were selected as the research subjects.According to the different surgery, the patients were randomly divided into control group(n=38) and observation group(n=38). The control group was given compound Danshen injection, while the observation group was given Toutongning capsule combined with nimodipine.The efficacy, the peak systolic velocity(Vs) and pulsatility index(PI) of each vessel, the time of stopping pain, recurrence rate and adverse reaction were compared between the two groups. Results The total effective rate of the observation group was 94.74%, which was higher than 84.21% of the control group, the difference was statistically significant (χ2=4.785, P<0.05). The MCA, ACA, BA, VA value of Vs and PI, the time of stopping pain and recurrence rate in the observation group were better than those in the control group(t=5.385, 6.834, 7.407, 6.651, 4.032, 5.716, 6.203, 5.016, 4.785, χ2=5.473, all P<0.05). There were no significant differences between the two groups in PCA value of Vs and PI and adverse reaction(t=0.283, 0.037, χ2=0.314, all P<0.05). Conclusion Toutongning capsule combined with nimodipine in the treatment of primary vascular headache has high application value and significant effect, and it can promote cerebral circulation, blood flow, time of stopping pain and recurrence rate, so it is worthy of clinical popularization and application.

Efficacy and safety of smiltiorrhizadepsidesal combined with conventional western medicine treatment for stable angina pectoris

In recent years, Chinese patent medicines such as smiltiorrhizadepsidesal(SMDS) injection are combined with western medicine to achieve good clinical efficacy for stable angina pectoris(SAP). SMDS is prepared by the water-soluble active ingredients extracted from Salvia miltiorrhiza, with the functions of promoting blood circulation, removing blood stasis and activating blood vessels, and it is used to treat type ⅠSAP and type ⅡSAP. The efficacy and safety of SMDS combined with simple routine western medicine for SAP were investigated by searching PubMed, EMbase, the Cochrane Library, CNKI, VIP, WanFang Data and CBM Database. SMDS combined with conventional western medicine treatment showed better efficacy for SAP as compared with western medicine alone, and better than other traditional Chinese medicines(such as Danshen injection and compound Danshen injection) combined with conventional western medicine. It was found that SMDS had a positive role in reducing blood viscosity, atherosclerosis, and improving microcirculation. The reported adverse drug reactions (ADRs) of SMDS combined with conventional western medicine therapy in clinical research were basically the same with ADRs reported by spontaneous reporting system(SRS) warning signals. Overall, SMDS combined with conventional western medicine had low incidence of ADR and no serious ADR occurred for SAP treatment in clinical trials. Currently, some drugs related to cardiovascular diseases such as ascinepazidemaleate injection, sodium succinate, propafenone hydrochloride and papaverine hydrochloride injection combined with SMDS have incompatibility, which should be highly emphasized in clinical use.

Meta-analysis on effect of compound Danshen injection in treating neonatal hypoxic-ischemic encephalopathy

To systematically evaluate the clinical efficacy and safety of compound Danshen injection in treating hypoxic-ischemic encephalopathy (HIE) of newborns. Computer retrievals were made in PubMed, Embase, Cochrane Library, CBM, CNKI, VIP and China info (before May 2014) and relevant literature references, and manual retrievals were made for journals and conference papers, in order to collect randomized or semi-randomized controlled trials concerning compound Danshen injection in the treatment of neonatal HIE. The quality of included references was evaluated according to literatures recommended by Cochrane Handbook. RevMan 5. 3 software was applied in the statistical treatment. Finally, a total of 13 randomized controlled trials were included, covering 1,211 patients (including 639 patients in the compound Danshen injection-treated group and 572 patients in the control group). Meta-analysis results showed that the routine treatment combined with compound Danshen injection can improve the treatment efficiency of neonatal HIE [RR = 1.28; 95% CI (1.21-1.36)], reduce the mortality rate [RR = 0.42; 95% CI (0.23-0.75)] and the incidence of long-term neurological sequelae [RR = 0.48; 95% CI (0.35-0.65)], with statistical differences. No fatal side effect was observed in all of included trials. So far, limited evidences in this study proved that the application of compound Danshen injection in the treatment of neonatal HIE can enhance the clinical efficiency. However, because of the low quality of the included trials, more well-designed and large-scale multi-center randomized controlled trials shall be made in the future.

Influence of compound Danshen injection on expressions of nitric oxide, B-cell lymphoma-2 and S100 in septic shock rats with brain injury

Objective To explore the influence of compound Danshen injection on the expressions of nitric oxide(NO), B-cell lymphoma-2(bcl-2)protein and S100 in the septic shock rats with brain injury. Methods Forty 2-week-old healthy Wistar rats were randomly divided into 4 groups, 10 cases in every group.Septic shock group 1(6 h)and septic shock group 2(12 h): the rats were injected with lipopolysaccharide (5 mg/kg) via the tail vein to make the septic shock models; and the treatment group: rats were intraperitoneally injected with compound Danshen injection (5 mg/kg) immediately when shock signs appeared; Normal control group: the rats were given the same amount of 9 g/L saline while the other groups received drugs; The septic shock group 2 were drawn 12 h after the successful mode-ling, while the remaining 3 groups were harvested at 6 h after the success of the modeling.The content of NO in the brain tissue was detected with nitrate reduction way, and the expression of bcl-2 in hippocampus was examined with immunohistochemistry technique, meanwhile the concentration of serum S100 was measured by enzyme linked immunosorbent assay. Results Compared with the normal control group, the contents of NO, bcl-2 and S100 in the septic shock 1 group increased significantly(F=25.64, 3 027.17, 632.04, all P<0.05); however in treatment group, the contents of NO and S100 were less than those in the septic shock groups, while the level of bcl-2 was more than that in the septic shock groups, and there were significant differences(F=25.64, 632.04, 3 027.17, all P<0.05); compared with the septic shock group 1, the contents of NO and S100 in the septic shock group 2 increased drastically, but the level of bcl-2 in the septic shock 2 group was decreased, and there were significant differences(t=-12.34, -4.89, 6.88, all P<0.05). NO and bcl-2 had significant negative correlation(r=-0.928, P<0.05); NO had significant positive correlation with S100(r=0.877, P<0.05). Conclusions NO participates in brain injury of septic shock rats, through inhi-biting bcl-2 expression and up-regulating S100 expression.Compound Danshen injection has a protective effect on the brain tissues of rats during septic shock, through reducing the contents of NO as well as S100 and elevating the expression of bcl-2. Key words: Compound Danshen injection; Septic shock; Nitric oxide; B-cell lymphoma-2 protein; S100

Protective function of compound Danshen injection on stress-induced gastric mucosal damage of rats

Objective To investigate the effects of compound Danshen injection on stress-induced gastric mucosal damage and its mechanism.Methods Sprague Dawley rats were used to establish immersion restraint cold stress model.50 SD rats were randomly divided into five groups(n=10 per group):① the normal control group; ② the stress model group; ③ the group treated with low dose of compound Danshen injection(50 mg/kg) ; ④ the group treated with medial dose of compound Danshen injection(100 mg/kg) ; ⑤the group treated with high dose of compound Danshen injection (200 mg/kg).The gastric mucosal ulcer index (UI),the level of malondialdehyde (MDA) in gastric mucosa,the activity of superoxide dismutase (SOD),and plasma intedeukin-1beta (IL-1β)content were detected.Results Compared with the normal control group [(0.7± 0.4) mm,(0.25 ± 0.03)nmol/mg,and (246.5 ± 45.4)Nu/mg],the stress model group exhibited a markedly increase in gastric mucosal UI[(28.4±4.5)mm](P＜0.01) and MDA level [(0.60±0.08)nmol/mg](P＜0.01) and a decrease in the activity of gastric mucosal SOD [(122.5 ±14.2) Nu/mg] (P＜0.01).In addition,an elevated level of plasma IL-1β[(31.6±8.4) pg/ml vs (8.5±3.1) pg/ml] (P＜0.01) was observed in the stress model group.Pretreatment with compound Danshen injection dose-dependently attenuated the gastric mucosal damage,characterized by a markedly decrease in gastric mucosal UI [(22.8 ± 3.7)mm、(12.2 ±3.5)mm,(6.2 ± 1.6)mm] and MDA level [(0.52 ± 0.07)nmol/mg,(0.32 ± 0.06)nmol/mg,(0.28 ±0.03)nmol/mg] and an increase in the activity of gastric mucosal SOD[(135.2± 13.6)Nu/mg,(220.7±33.5)Nu/mg,(251.2±23.7)Nu/mg] (P＜0.01).Meanwhile,compound Danshen injection reduced the content of plasma IL-1β[(27.2±7.5)pg/ml,(13.5±5.3)pg/ml,(9.3±4.4)pg/ml] (P＜0.01).Conclusion Compound Danshen injection exhibits preventive protection on the stress-induced gastric mucosal damage by water immersion restraint cold stress in SD rats,the mechanism of which might be linked to its inhibition of gastric mucosal oxidation stress and the reduced release of inflammatory mediator IL-1β.

The stability investigation of compound Danshen injection (a traditional medicine) with a new high-performance liquid chromatography method

Background:Compound Danshen injection (CDSI, a traditional medicine) is an effective drug for the treatment of cardiovascular and cerebrovascular diseases. However, the research about its stability is absent.Objective:A new high-performance liquid chromatography method was developed to assay its main effective constituents, i.e., propanoid acid (PA), protocatechuic aldehyde (PHA), salvianolic acid B (SAB), salvianolic acid A (SAA), and rosmarinic acid (RA). Through the newly found method, the stability of CDSI was to be investigated.Materials and Methods:The analysis was performed by a reverse-phase gradient elution using an aqueous mobile phase (containing 0.1% acetic acid) modified by acetonitrile, and detection was made simultaneously at 280 nm and 325 nm. The method was validated for accuracy, precision and limits of detection. The effects of some environmental storage conditions (light and temperature) on the stability of CDSI were investigated.Results:This method is precise, simple, and convenient. The result showed that illumination and temperature had an obvious effect on CDSI's stability. SAA is the most unstable one among the five components. In the condition of common light, it decomposed rapidly to almost 50% after only 4 h, and 100% after 8 h. PA, RA, and PHA might come from Danshen, was also the transformed products from other components in store process.Conclusion:The result indicated that the main active constituents in CDSI suffered from the illumination and temperature greatly. CDSI should be stored at low temperature and kept away from light.

Compound Danshen injection improves endotoxin-induced microcirculatory disturbance in rat mesentery

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. 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. The continuous infusion with LPS resulted in a number of responses in microcirculation, including a significant increase in the positive region of venule stained 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. These results suggest that compound Danshen injection is an efficient drug with multi-targeting potential for improving the microcirculatory disturbance.
