ABSTRACT
Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.
ABSTRACT
Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.
ABSTRACT
Objective:To assess the efficacy and safety of cinepazide maleate injection in the treatment of patients with acute ischemic stroke.Methods:A multicenter, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial, led by Peking Union Medical College Hospital, was conducted in 65 Hospitals in China. The efficacy of cinepazide maleate injection in patients with acute anterior circulation cerebral infarction with onset time of ≤48 hours, 7≤National Institute of Health stroke scale (NIHSS) score ≤25 was assessed from August 2016 to February 2019, using the proportion of modified Rankin scale (mRS) score≤1 and Barthel index (BI) score≤95 on day 14 as efficacy endpoint. The patients were divided into treatment group who were treated with cinepazide maleate injection and control group who were treated with placebo.Results:A total 937 patients were involved in the final efficacy analysis (466 in treatment group and 471 in control group). The proportion of subjects with mRS score≤1 on day 14 after treatment were higher in the treatment group than that in the control group (102/466(21.89%) vs76/471(16.14%)). Logistic regression analysis showed that patients treated with cinepazide maleate were significantly more likely to have a favorable outcome (mRS score≤1) than patients treated with placebo on day 14 ( OR=0.677, 95% CI 0.484-0.948 , P=0.023), and patients treated with cinepazide maleate were more likely to reach independence in activities of daily living (Barthel Index ≥95) than those treated with placebo on day 14 (125/466(26.82%) vs 91/471(19.32%); OR=0.632, 95% CI0.459-0.869, P=0.005). The rate of adverse events was similar between the treatment and control groups. Conclusion:The 14-day treatment with cinepazide maleate injection could reduce the degree of disability whereas did not increase the risk of adverse events.

ABSTRACT
OBJECTIVE To study the anti-tumor activity and molecular mechanism of natural diter-pene derivative JD20 in vitro. METHODS Screening the sensitive of gastric carcinoma cell lines to JD20 by cytotoxicity test for 24 h.Cell morphology was evaluated by using DAPI.After staining of can-cer cells with PI or annexin V-FITC/PI respectively,the cell cycle and apoptosis induced by JD20 were detectded by flow cytometry. The change in cell membrane potential was detected by JC-1 test kit. Western blot method was used to detect the apoptosis-related protein. RESULTS The novel natural kaurane diterpene derivative JD20 had a significant inhibitory effect on tumor cells and was particularly active on gastric cancer cell lines HGC-27 (IC50=4.72 ± 1.37 μmol·L- 1) and MGC-803 (IC50=7.36 ± 0.86 μmol·L-1).Further studies found that JD20 resulted in thecell cycle arrest in the G2/M phase,and induced a significant apoptosis in HGC-27. In addition, JD20 also caused the drop of mitochondrial membrane potential of HGC-27 within a short time (3 h). Furthermore, the Western blotting analysis showed that JD20 could induce the up-regulation of p53,Bax and Bim protein expression in gastric can-cer cells,and the releasing of cytochrome c from the mitochondria into the cytoplasm,as well as the ac-tivation of casepase-9/3.CONCLUSION The natural kaurane diterpene derivative JD20 can inhibit the proliferation of various human cancer cells by blocking the cell cycle and inducing apoptosis, and its mechanism of inducing apoptosis may be related to the mitochondria-mediated apoptosis pathway.
ABSTRACT
OBJECTIVE To probe into the anti-esophagus cancer activity and mechanisms of DN3, a novel natural diterpenoid derivative. METHODS The anti-tumor activity in vitro of DN3 was evaluated by MTT, and by using human esophageal carcinoma cells xenografted into athymic mice model in vivo. The specific mechanisms of DN3, as a dual inhibitor of glycolysis and oxidative phos-phorylation(OXPHOS)were explored through cell and molecular biology techniques.For instance,the manner of cancer cell death induced by DN3 was characterized by hoechst33342, FITC-Annexin V/PI staining and flow cytometric analysis,then these changes of glucose consumption,glucose uptake and lactate production in glycolysis, as well as oxygen consumption rate (OCR) and ATP content in OXPHOS caused by DN3 were performed separately through related kits and SeahorseBioscience XF24 Extra-cellular Flux Analyzer.Furthermore,in order to obtain a clear understanding of the inhibition of DN3 to glycolysis and OXPHOS, these regulatory factors were investigated by Western blot, such as PI3K/AKT, c-Myc and p53 of glycolysis, Bax and HK2 of mitochondrial function. RESULTS DN3 inhibited the growth of esophagus cancer cell EC9706, EC109 and EC1 cells in a dose and time dependent manner,but showed no significant effects on human esophageal epithelial cells(HEECs).DN3 caused significant G2/M arrest of esophagus cancer cell lines and induced apoptosis of these cell lines, which indicated DN3 inhibited the growth of esophagus cancer cell through blocking cell cycle and inducing apoptosis in a dose and time-dependent manner. Importantly, 8 μM DN3 decreased the extracellular acidification rate (ECAR) by 45% in EC109, which indicated glycolysis was inhibited by DN3. Mean-while, DN3 decreased the oxygen consumption rate (OCR) and the OCR linked to intracellular ATP production in EC109 cells,but that was not obvious in HEECs,so which indicated that DN3 could selec-tively block OXPHOS of cancer cells. In addition, the accumulation of reactive oxygen species (ROS) and the drop of mitochondrial membrane potential (MMP) were also observed in EC109 incubated by DN3,which suggested mitochondrial biological function was disturbed.Furthermore,the expression of PI3K/AKT, c-Myc and HK2 related to glycolysis were down-regulated by DN3, but the p53 and Bax were up-regulated in esophageal carcinoma cells. The changes of these enzymes accounted for the decreased glycolysisand OXPHOS in esophageal carcinoma cells treated by DN3. CONCLUSION The new compound DN3 has a strong anti-esophageal carcinoma activity,and it is tolerable that DN3 is seen as a dual inhibitor of glycolysis and oxidative phosphorylation.
ABSTRACT
OBJECTIVE Gastric cancer is one of the most common malignant tumors,and the inci-dence rate is the highest in all kinds of tumors in China. However,it remains unclear that how signifi-cantly gastric cells are dependent on glycolysis,and which type of gastric cells are sensitive to glycolysis inhibition. In this study, several kind of gastric cancer cell lines were used as the research object, and the metabolic characteristics of different cell lines were systematically analyzed to provide theoretical support for the accurate treatment of gastric cancer. METHODS We examined the energy metabolism of four gastric cancer cell lines(MGC-803,SGC-7901,HGC-27 and BGC-823)by using glycolysis inhibitor, 2-deoxy-D-glucose(2-DG)and inhibitor of oxidative phosphorylation,oligomycin.Oxygen consumption rates(OCR)and L-lactate were also measured with an XF96 Analyzer(Seahorse Biosciences)to deter-mine the significance of metabolism of oxidative phosphorylation and aerobic glycolysisin gastric cells. In addition, western blot was used to detect the contribution of AMP-activated protein kinase (AMPK), and anti-apoptotic proteins(Bcl-2 and survivin)to clarify the mechanism of death or survival of gastric cancer cells treated by 2-DG or oligomycin. RESULTS In this study, it was shown that the growth of gastric cell lines were suppressed by 2-DG.However,the sensitivity to 2-DG was quite different among cell lines:IC 50 of 2-DG was from 3.28 mmol·L-1(MGC-803)to 15.57 mmol·L-1(BGC-823).MGC-803 was relatively sensitive to 2-DG (IC 50:3.28 mmol·L-1), consumed more glucose and produced more lactate (waste product of glycolysis) than the three other cell lines. Consequently, MGC-803 could be more dependent on glycolysis than other cell lines, which was further confirmed by the fact that glucose (+)FCS(-)medium showed more growth and survival than glucose(-)FCS(+)medium.Alternatively, BGC-823, most resistant to 2-DG (IC50: 15.57 mmol·L- 1), was most sensitive to oligomycin, and showed more growth and survival in glucose(-)FCS(+)medium than in glucose(+)FCS(-)medium. Thus,we had reasons to think BGC-823 cells depended on oxidative phosphorylation for energy production. In BGC-823,AMPK,which is activated when ATP becomes limiting,was rapidly phosphorylated by 2-DG, and expression of Bcl-2 was augmented,which might result in resistance to 2-DG.Interestingly,AMPK phosphorylation and augmentation of Bcl-2 expression by 2-DG were not observed in MGC-803,which is 2-DG sensitive. CONCLUSION There is a large metabolic difference between gastric cancer cell lines,which will facilitate the future gastric cancer therapy by targeting metabolic pathways.
ABSTRACT
Objective To investigate the effects of monosodium tetrahexose ganglioside sodium (GM-1) combined with edaravone in the treatment of acute cerebral infarction (ACI) in patients with serum homocysteine (Hcy), high sensitivity C-reactive protein (Hs-CRP). Methods 66 patients with ACI were randomly divided into observation group and control group, 33 cases were treated with conventional neurology. The control group was treated with edaravone. The observation group was treated with edaravone and GM-1. (NIHSS) score, serum hs-CRP and Hcy levels were compared between the two groups. Results The total effective rate of the observation group was 90.91%, which was significantly higher than that of the control group (P<0.05). After 21 days of treatment, the NIHSS score, serum Hcy and hs-CRP in the observation group were significantly lower than those in the control group (P<0.05 ). Conclusion GM-1 combined with edaravone is effective in the treatment of ACI, which can promote the rehabilitation of neurological function and living activity. Its mechanism may be related to its anti-inflammatory response, reduced Hcy level and protection of brain cell injury.
ABSTRACT
As a kind of nervous system disease,migraine is more common in female,and has the clinical characteristics of repeated attacks,it is of great significance with standardized treatment in the control of the attacks.Yong female patients with migraine during pregnancy and lactation stage will face lots of special problems because they must first consider the impact of treatment on the mother and fetus.Generally,non-drug therapy is recommended as a first-line treatment,if it is not sufficiently effective,paracetamol is recommended during the pregnancy or sporadic use of sumatriptan,NSAIDs is not recommended during the first or third trimester of pregnancy.Preventive therapy should only be considered in the most severe cases.This review summarized recent documents of the safety of the most used antimigraine medications during pregnancy and breastfeeding,in order to provide treatment recommendations in clinical practice.
