RESUMEN

Evaluating the consistency of herb injectable formulations could improve their product quality and clinical safety, particularly concerning the composition and content levels of trace ingredients. Panax notoginseng Saponins Injection (PNSI), widely used in China for treating acute cardiovascular diseases, contains low-abundance (10%-25%) and trace saponins in addition to its five main constituents (notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, and ginsenoside Rd). This study aimed to establish a robust analytical method and assess the variability in trace saponin levels within PNSI from different vendors and formulation types. To achieve this, a liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS) method employing multiple ions monitoring (MIM) was developed. A "post-column valve switching" strategy was implemented to eliminate highly abundant peaks (NR1, Rg1, and Re) at 26 min. A total of 51 saponins in PNSI were quantified or relatively quantified using 18 saponin standards, with digoxin as the internal standard. This study evaluated 119 batches of PNSI from seven vendors, revealing significant variability in trace saponin levels among different vendors and formulation types. These findings highlight the importance of consistent content in low-abundance and trace saponins to ensure product control and clinical safety. Standardization of these ingredients is crucial for maintaining the quality and effectiveness of PNSI in treating acute cardiovascular diseases.

RESUMEN

OBJECTIVE To evaluate the efficacy, safety and economical efficiency of Xuesaitong injection in the treatment of stroke by rapid health technology assessment,so as to provide evidence for clinical rational drug use. METHODS Retrieved from Wanfang database, CBM, CNKI,PubMed,Cochrane Library,Embase, INAHTA and HTAI databases or organization websites, health technology assessment (HTA) reports, meta-analysis/systematic reviews and pharmacoeconomic studies related to Xuesaitong injection in the treatment of stroke were summarized and analyzed. RESULTS A total of 29 pieces of literature were included. Among them, 14 studies were conducted on meta-analysis/systematic reviews,15 studies were conducted on pharmacoeconomics, HTA was not obtained. The results of meta-analysis/systematic reviews showed that Xuesaitong injection had certain advantages for stroke in improving the total effective rate, clinical symptoms and related scale scores compared with blank control group and some drug control groups. Safety studies had shown that the adverse reactions of Xuesaitong injection were mainly allergic-like reactions. The results of pharmacoeconomic evaluation are quite different, which may also be related to the long time span among various studies and the adjustment of some drug prices. CONCLUSIONS Xuesaitong injection in the treatment of stroke is helpful to improve the clinical efficacy and evaluation indexes, but there are some serious adverse reactions, and it is not economically superior to some chemical drugs.

RESUMEN

The present study determined five saponins in Xuesaitong Dropping Pills(XDP) by micellar electrokinetic chromatography(MEKC), and evaluated between-batch consistency by MEKC fingerprints and similarity analysis. A background buffer was composed of 20 mmol·L~(-1) sodium tetraborate-20 mmol·L~(-1) boric acid solution(pH 8.5), 55 mmol·L~(-1) sodium dodecyl sulfate(SDS), 23 mmol·L~(-1) β-cyclodextrin, and 13% isopropyl alcohol. All separations were performed at 25 ℃,20 kV and the detection wavelength was set at 203 nm. The separation channel was a fused silica capillary with a dimension of 75 μm I.D. and a total length of 50.2 cm(effective length of 40.0 cm). The contents of notoginsenoside R_1, and ginsenosides Rg_1, Re, Rb_1, Rd were determined with their quality control ranges set. The fingerprints of XDP were established and the between-batch consistency was evaluated by similarity analysis. The contents of five saponins from the 19 batches of XDP were stable in the fixed ranges. Statistical analysis was carried out on the results of multiple batches of samples, and the specific quality control ranges were recommended as follows: notoginsenoside R_1 21.92-34.16 mg·g~(-1), ginsenosides Rg_1 83.54-131.78 mg·g~(-1), ginsenosides Re 13.58-19.82 mg·g~(-1), ginsenosides Rb_1 89.40-129.90 mg·g~(-1), and ginsenosides Rd 22.34-35.67 mg·g~(-1). Eleven characteristic peaks were identified in the fingerprints. Five peaks, notoginsenoside R_1 and ginsenosides Rg_1, Re, Rb_1, Rd, were identified with reference standards. The similarities of the 19 batches of samples were all above 0.988, indicating good between-batch consistency. This method is green and simple, and can be used for the quantitative determination and quality evaluation of XDP. It can also provide references for the quality control of other Chinese medicinal dripping pills.

RESUMEN

With the dropping process of Xuesaitong Dropping Pills(XDP) as the study object, critical factors affecting the quality indicators of pill pass rate, average weight of drop pills and roundness were screened out, so as to deepen the understanding of the dropping process. The critical process units, critical quality attributes and potential critical process influencing factors of XDP were determined by risk analysis and prior knowledge, and then the critical influencing factors were screened out by Plackett-Burman design. First, according to the risk assessment, the critical technique of XDP preparation process was dropping, and then the critical quality attributes of dropping process were pill pass rate, average weight of drop pills and roundness. Then, according to fishbone diagram and failure mode and effects analysis(FMEA), potential critical influencing factors were determined as flow rate, matrix ratio, solid-liquid ratio, feed-liquid temperature, top temperature of condensate, bottom temperature of condensate and dropping distance. Finally, among these seven potential factors, the critical influencing factors were determined as material liquid ratio, dropping distance, top temperature of condensate, bottom temperature of condensate. This study revealed the potential of Plackett-Burman design in screening and understanding the influence of selected factors on XDP dropping process, which could provide a reference for studying the dropping process.

RESUMEN

Aim To explore the feasibility of APTT bioactivity detection for Xuesaitong injection. Methods The APTT values of rabbit plasma of samples/reference were detected by automatic coagulometer, and the data were analyzed by bioassay statistics. Results The results of repeated test of different rabbit plasma, multiple enterprises and various concentrations of Xuesaitong injection were stable. The APTT values of standard ginsenoside Rb1, ginsenoside Rg1, notoginsenoside R1 and Panax notoginseng saponins were compared with that of Xuesaitong injection, and the APTT values of the former three were not correlated with Xuesaitong injection; while the Panax notoginseng saponins were significantly correlated with Xuesaitong injection. The panax notoginseng saponins were used as the reference material, and the results were consistent with those of the physical and chemical analysis. Conclusions The active ingredients in Xuesaitong injection do not represent the effective ingredients, and its medicinal effect is the result of the combined action of various ingredients. Therefore, it is not suitable to simply look for some monomer as the control. This paper suggests using panax notoginseng saponins as the control substance to explore the biological activity study of injections for promoting blood circulation and removing blood stasis.

RESUMEN

Objective: To establish the fingerprint of Xuesaitong Dropping Pills (XDP) using ultra-high pressure liquid chromatography (UPLC), determine the content of its main components and propose a chemometrics method for the systemic, comprehensive and scientific quality evaluation. Methods: The Agilent 1290 UPLC and Acquity UPLC BEH C18 column were used for the establishment of the UPLC fingerprints of 14 batches of XDP with acetonitrile and water as mobile phase for gradient elution, and the content of five kinds of notoginsenosides wsa determined. Then, the further quality assessment of XDP was carried out with similarity evaluation, principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Meanwhile, the Hotelling’s T2 and DModX control ranges were set for the different batches of samples. Results: Among the 14 batches, the content of five kinds of notoginsenosides was relatively stable, and the quality control ranges for notoginsenosides R, ginsenoside Rg1, Re, Rb1, Rd were set at 24.69-30.03 mg/g, 102.60-122.44 mg/g, 12.93-15.45 mg/g, 99.74-112.12 mg/g, and 23.35-31.75 mg/g, respectively. In this research, 15 chromatographic peaks were recognized as common peaks in the fingerprints, five peaks were identified with standard references compounds, which were notoginsenoside R1, ginsenoside Rg1, ginsenoside Re,ginsenoside Rb1 and ginsenoside Rd. The similarity values of the drugs were all above 0.998. In the PCA analysis, 14 batches of samples had no abnormal batch, indicating that the quality was relatively stable, however, the difference of the storage time was reflected in the fingerprint. According to the OPLS-DA result, the quantitative ginsenoside Rb1 and ginsenoside Rd had greater influence on the variables causing the gradual trend in 14 batches of samples. The upper limit of control for Hotelling’s T2 and DModX was 31.17 and 1.82, respectively. Conclusion: The established method was accurate, reliable, and simple. It can be used not only for the quality control of XDP, but also for the comprehensive evaluation of batch consistency. The study also provides a reference for solving the common problem of the consistency evaluation of Chinese materia medica.

RESUMEN

Objective: To establish an oxygen and glucose deprivation model (OGD) of SH-SY5Y cells, and investigate the effects of Xuesaitong Injection on the cell survival, apoptosis rate of SH-SY5Y cells and the mRNA and protein expressions of Lingo-1. Methods: The model was established using 1640 sugar-free medium and three-gas incubator. The cell survival rate was determined by CCK8 method to determine the optimal time for hypoxia and the optimal concentration of Xuesaitong Injection. The apoptosis rate of SH-SY5Y cells was detected by Annexin V-FITC/PI double staining. The mRNA and protein expressions of Lingo-1 were determined by qRT-PCR and Western blotting, respectively, and the effect of Xuesaitong on Lingo-1 expression was finally determined. Results: In this study, the optimal hypoxia time for the establishment of the OGD model of SH-SY5Y cells was 16 h and the optimum concentration of Xuesaitong Injection was 640 mg/L. The apoptosis rate of SH-SY5Y cells was significantly reduced, and the expression levels of lingo-1 mRNA and protein were decreased in the Xuesaitong group compared with the model group under the condition of this concentration. Conclusion: The apoptosis rate was significantly increased and Lingo-1 was highly expressed when SH-SY5Y cells were damaged by oxygen and glucose deprivation. Xuesaitong can significantly reduce the apoptosis of SH-SY5Y cells induced by oxygen and glucose deprivation, and inhibit the high expression of lingo-1, which has the anti-apoptosis and significant neuroprotective effect.

RESUMEN

Objective To investigate the effect of Xuesaitong injection on acute inflammatory response and preoperative cognitive dysfunction (POCD) in patients after gynecological laparoscopic surgery. Methods From July 2016 to September 2017, there were 246 patients having undergone gynecological laparoscopic surgery in the Department of Obstetrics and Gynecology of Guangyuan Central Hospital. And according to whether Xueseton was used or not preoperatively, they were divided into a control group (n = 118) and an observation group (n =128). The patients in the observation group were given intravenous drip with 400 mg Xuesaitong at 30 minutes before surgery, while the patients in the control group were given intravenous drip with equal amount of 5% glucose solution at 30 minutes before surgery. The enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of interleukin-1 and -6 (IL-1, IL-6) and tumor necrosis factor-α (TNF-α); the neuropsychological tests were used to assess the patients' cognitive function; visual analogue scale (VAS) score was applied to assess the postoperative pain of patients; the intra-operative situation and the postoperative related risk occurrence were recorded in the two groups. Results The comparisons of indicators between the observation group and control group were as follows: the operation time (minutes: 106.2±30.6 vs. 114.6±22.7), anesthesia time (minutes: 126.1±21.2 vs. 122.1±25.3), intra-operative blood loss (mL: 324.4±63.1 vs. 313.6±65.1) and postoperative rash (1 case vs. 2 cases), chest distress (11 cases vs. 8 cases), palpitation (10 cases vs. 8 cases), asthma (5 cases vs. 4 cases), hematuria (2 cases vs. 3 cases), incision bleeding (4 cases vs. 3 cases), lower limb deep venous thrombosis (DVT: 11 cases vs. 14 cases) and VAS score (3.6±0.9 vs. 3.8±0.8), prothrombin time [PT (s): 10.7±2.2 vs. 9.7±1.5], activated partial thromboplastin time [APTT (s): 30.3±3.3 vs. 30.7±4.3], international normalized ratio (INR: 0.9±0.1 vs. 1.1±0.1), all of the above comparisons in indexes between the two groups had no statistical significant differences (all P > 0.05); with prolonged treatment, the IL-1, IL-6 and TNF-α levels were gradually decreased in two groups, reached the lowest levels at 12 hours after surgery, and the changes in the observation group were more significant than those in the control group [IL-1 (pg/L): 3.8±1.0 vs. 6.5±1.2, IL-6 (pg/L): 6.3±1.3 vs. 10.3±1.6, TNF-α (pg/L): 5.6±1.3 vs. 8.4±1.2]; after surgery the scores of MMSE test (score: 25.8±3.1 vs.20.8±3.3) and the word fluency test (14.9±1.8 vs. 12.8±1.8) in the observation group were significantly higher than those in the control group, while the incidence of POCD was significantly lower than that in the control group [18.7% (24/128) vs. 33.8% (40/118), all P < 0.05]. Conclusion The use of Xuesaitong before gynecological laparoscopic surgery can reduce the patients' expression levels of serum IL-1, IL-6 and TNF-α at acute inflammatory stage, reduce the occurrence of POCD and does not increase the related risk after surgery.

RESUMEN

OBJECTIVE: To investigate the effects of Xuesaitong for injection on microembolic signal (MES) and blood lipid of patients with middle cerebral artery (MCA) atherosclerotic stenosis complicated with MES positive transient ischemic attack (TIA). METHODS: A total of 98 patients with MCA atherosclerotic stenosis complicated with MES positive TIA in the Affiliated Hospital of Chengdu University of TCM during May 2015-May 2016 were divided into routine group and Xuesaitong group according to random numble table, with 49 cases in each group. Routine group received routine treatment. Xuesaitong group was additionally given Xuesaitong for injection (lyophilized) 400 mg intravenously, once a day, for consecutive 15 d, on the basis of routine treatment. The distribution of MES classification and the number of MES were observed in 2 groups before treatment, 15 d after treatment and 3rd and 6th month after treatment. The levels of TG, TC, LDL were observed before treatment and 15 d after treatment. The occurrence of ischemia event and ADR were recorded. RESULTS: Fifteen days after treatment, the distribution of MES classification in 2 groups was significantly better than before treatment; Xuesaitong group was significantly better than routine group, with statistical significance (P<0. 05). At 3rd and 6th month after treatment, the distribution of MES classification in Xuesaitong group was significantly better than routine group; 6th month after treatment was significantly better than 3rd month after treatment, with statistical significance (P<0. 05). Fifteen days and the 3rd, 6th month after treatment, the number of MES in 2 groups were significantly lower than before treatment and decreased as time; Xuesaitong group was significantly lower than routine group, with statistical significance (P<0. 05). Fifteen days after treatment, TG and TC levels of 2 groups were significantly lower than before treatment; Xuesaitong group was significantly lower than routine group, with statistical significance (P<0. 05); there was no statistical significance in the level of LDL before and after treatment (P>0. 05). The incidence of ischemic events in routine group at 6th month after treatment was significantly higher than 3rd month after treatment, and the incidence of ischemic events in Xuesaitong group at 3rd and 6th month after treatment was significantly lower than routine group, with statistical significance (P<0. 05). At 6th month after treatment, the incidence of ADR in 2 groups was significantly lower than 3rd month, with statistical significance (P<0. 05). CONCLUSIONS: Based on routine treatment, Xuesaitong for injection can reduce the number of MES, reduce the incidence of ischemia events and further improve the level of blood lipid in patients with MCA atherosclerotic stenosis complicated with MES positive TIA without increasing the occurrence of ADR.

RESUMEN

Objective: To investigate the protective effects of the combination of Xuesaitong (XST) and aspirin on cerebral ischemia and reperfusion injury (CIRI) in rats, and further explore the underlying mechanisms. Methods: A total of 150 male Sprague-Dawley (SD) rats were randomly divided into five groups with 30 rats in each group: sham group, middle cerebral artery occlusion/reperfusion (MCAO/R) model group, XST group, aspirin group, and XST + aspirin group. Rats were pretreated with XST, aspirin, or XST + aspirin for 7 d. One hour after the last administration, a model of CIRI was induced by MCAO/R. Neurological deficits were assessed using Longa's five-point scale. Cerebral edema was detected by the measurement of brain water content. The volume of cerebral infarction was determined by 2,3,5-triphenyltetrazolium chloride (TTC) staining. The activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), as well as levels of malonaldehyde (MDA) were detected by commercial kits. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of interleukin-1 (IL-1β), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein 1 (MCP-1), and kynurenine in serum, cerebral cortex, and hippocampus of MCAO/R rats. The protein expression of nuclear factor erythroid 2-related factor (Nrf2), heme oxygenase-1 (HO-1), I-kappa B alpha (IκBα), and nuclear factor kappa B (NF-κB)/p65 in the cortex were analyzed by western blotting. Results: Treatment of XST, aspirin, and XST + aspirin significantly alleviated the neurological deficits, cerebral edema, and cerebral infarct volume induced by MCAO/R. Treatment of XST, aspirin, and XST + aspirin also reduced MDA, IL-1β IL-6,TNF-α MCP-1, and kynurenine levels, and increased SOD, CAT, GSH-Px, IL-4, and IL-10 levels in serum, cerebral cortex, and hippocampus of MCAO/R rats. Furthermore, treatment of XST, aspirin, and XST + aspirin decreased the expression of nuclear NF-κB/p65 and increased the expression of IκBα nuclear Nrf2, and HO-1. Importantly, the combination of XST and aspirin enhanced the protective effects of XST or aspirin treatment alone on CIRI in rats. Conclusion: The combination of XST and aspirin significantly inhibited oxidative stress and inflammation in serum, cerebral cortex, and hippocampus of MCAO/R rats. The combination of XST and aspirin exerted more protective effects than XST or aspirin treatment alone. The combination of XST and aspirin might provide the synergistic therapeutic effects on CIRI, and deserve further clinical investigation.

RESUMEN

OBJECTIVE:To explore the effects of Xuesaitong injection on related indexes of patients with acute ST segment el-evation myocardial infarction(STEMI)before percutaneous coronary intervention(PCI). METHODS:112 STEMI patients under-went PCI were analyzed retrospectively and divided into control group (48 cases) and observation group (64 cases) according to different treatment methods. Control group was given Clopidogrel sulfate tablets 300 mg and Aspirin enteric-coated tablets 300 mg orally before PCI;given conventional treatment according to patients'condition after surgery. Observation group additionally re-ceived intravenous push of Xuesaitong injection 8 mL before surgery,and Xuesaitong injection 8 mL added into Sodium chloride 250 mL intravenously,once a day after surgery,on the basis of control group. Treatment course of 2 groups lasted for 14 d. TIMI level,MPG level,the serum levels of cTnT,CKMB were observed in 2 groups before surgery,24 h after surgery;serum level of PTX-3,hs-CRP were observed before surgery,one week after surgery;LVEF,LVEDD,serum level of BNP were observed before surgery and one month after surgery;the occurrence of ADR was observed to. RESULTS:Before surgery,there was no statistical significance in TIMI level,MPG level,the serum levels of cTnT,CKMB,PTX-3 and hs-CRP,LVEF,LVEDD,serum level of BNP between 2 groups (P>0.05). 24 h after surgery,TIMI level and MPG level of 2 groups were significantly higher than be-fore,and the observation group was significantly higher than the control group;the serum levels of cTnT and CKMB in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical sig-nificance(P0.05). CONCLUSIONS:Based on convention-al treatment,Xuesaitong injection can effectively improve myocardial blood supply before PCI,decrease the level of inflammatory factor,relieve myocardial injury,improve cardiac function without increasing the incidence of ADR.

RESUMEN

The present study aims to investigate the effects of Xuesaitong (XST)injection on inflammation induced by OGD/reoxygenation in BV2 microglia cell and explore the underlying mechanisms.The effects of XST injection were evaluated in terms of cell viability, secretion of TNF-α, IL-1β, IL-6 and IL-10 into culture media, protein expression of p-ERK1/2, p-JNK and p-p38, and nuclear translocation of NF-κB p65. The results showed that XST injection significantly increased cell viability, suppressed release of TNF-α, IL-1β, IL-6 and IL-10 and down-regulated p-JNK1/2 and p-p38 MAPK expression in BV2 microglia cells induced by OGD/R injury, whereas it had no effect on p-ERK1/2 expression. Furthermore, XST injection suppressed nuclear translocation of NF-κB p65 in BV2 microglia after OGD/R injury. These data indicate that the neuroprotective effects of XST injection on OGD/R injury are associated with its inhibition of pro-inflammatory mediator production, down-regulation of JNK1/2 and p38 MAPK activation, and suppression of NF-κB p65 nuclear translocation in BV2 microglia cells.
