Methods: Cerebral ischemia was established by occluding the middle cerebral artery with an intraluminal suture technique in rats. Neurological deficit score, infarct volume and quantity of NMDA receptors were estimated in all groups and compared. Results: After being treated with XNJ, the score decreased in the initial 6 hours and infarct volume decreased in 24 hours. And within 24 hours, the quantity of NMDA receptors obviously decreased compared with the model group (P<0. 01) It indicated that XNJ could ameliorate neurological behavior of middle cerebral artery occlusion rats and down-regulate the expression of hippocampal NMDA receptors. Conclusion: The neuroprotective effect of XNJ on focal cerebral ischemia is possibly related to down-regulating the expression of NMDA receptors in rats.展开更多

Middle cerebral artery occlusion(MCAO) ...The aim of this study was to explore the neuroprotective effect and mechanism of XingNaoJing injections(XNJ) on cerebral ischemia injury and blood-brain barrier(BBB) disruption. Middle cerebral artery occlusion(MCAO) method was applicated to establish the model of cerebral ischemia/reperfusion(I/R) injury in rats. BBB permeability after I/R injury was assessed with the leaking amount of Evans Blue and the expression of occludin and ZO-1. The expression of NOD-like receptor family, pyrin domain containing(NLRP3) was checked to explore the inhibition of inflammation by XNJ. The results showed that XNJ could significantly increase the survival percent, decrease the infarct area and ameliorate neurological deficits and brain damage after I/R injury. Leaking amount of Evans Blue was reduced by XNJ, and the expression of tight junction protein, occludin and ZO-1 was also up-regulated by XNJ, which showed a role of protection on BBB disruption. The expression of NLRP3 was inhibited after exposure of XNJ, which was associated with inhibition of the inflammatory response. In summary, XNJ could suppress NLRP3 inflammasomes and improve BBB disruption and brain damage in rats after cerebral I/R injury, which provided a beneficial insight to further explore XNJ.展开更多

Methods: An integrated protocol that combines in silico target screen (molecular docking) and database mapping was employed to find the potential inhibitors from XNJI for the sepsis-related targets and to establish the compound-target (C-T) interaction network. The XNJI's bioactive components database was investigated and the sepsis-associated targets were comprehensively constructed; the 3D structure of adenosine receptor A2a and 5-1ipoxygenase proteins were established and evaluated with homology modeling method; system network pharmacology for sepsis treatment was studied between the bioactive ingredients and the sepsis targets using computational biology methods to distinguish inhibitors from non inhibitors for the selected sepsis-related targets and C-T network construction. Results: Multiple bioactive compounds in the XNJI were found to interact with multiple sepsis targets. The 32 bioactive ingredients were generated from XNJI in pharmacological system, and 21 potential targets were predicted to the sepsis disease; the biological activities for some potential inhibitors had been experimentally confirmed, highlighting the reliability of in silico target screen. Further integrated C-T network showed that these bioactive components together probably display synergistic action for sepsis treatment. Conclusions: The uncovered mechanism may offer a superior insight for understanding the theory of the Chinese herbal medicine for combating sepsis. Moreover, the potential inhibitors for the sepsis-related targets may provide a good source to find new lead compounds against sepsis disease.展开更多

文摘Background:Epilepsy is characterized by acute recurrent seizures.The control of seizures is largely hampered by the tolerance to current anti-seizure drugs.Complementary anti-convulsant pharmacotherapies are urgently needed.Objective:Here,we aimed to investigate the anti-convulsant effects of Xingnaojing Injection(XNJ)which is an approved Traditional Chinese Medicine injection on different acute seizure models in mice.Methods:The effects of XNJ were tested on the maximal electroshock(MES),pentylenetetrazol(PTZ)and kainic acid(KA)acute seizure models.Also,whether XNJ can directly inhibit hippocampal neuronal firings were exam-ined by in vitro electrophysiology.Results:XNJ could shorten the durations of generalized tonic-clonic seizures in the MES model.It also significantly prolonged the latencies to generalized myo-clonic seizures in the PTZ model.In the KA model,XNJ showed various efficacies including inhibiting the seizure stages,prolonging the latency to the occurrence of the first seizures or generalized seizures,shortening the seizure durations,decreasing the numbers of generalized seizures.In vitro electrophysiological recordings further verified XNJ directly inhibited both the spontaneous and evoked action potentials of hippocampal pyramidal neurons,but did not influence the excitatory or inhibitory synaptic transmissions.Conclusion:These findings proposed XNJ as an alternative anti-convulsant pharmacotherapy for controlling acute epileptic seizures.

文摘The aim of this study was to explore the neuroprotective effect and mechanism of XingNaoJing injections(XNJ) on cerebral ischemia injury and blood-brain barrier(BBB) disruption. Middle cerebral artery occlusion(MCAO) method was applicated to establish the model of cerebral ischemia/reperfusion(I/R) injury in rats. BBB permeability after I/R injury was assessed with the leaking amount of Evans Blue and the expression of occludin and ZO-1. The expression of NOD-like receptor family, pyrin domain containing(NLRP3) was checked to explore the inhibition of inflammation by XNJ. The results showed that XNJ could significantly increase the survival percent, decrease the infarct area and ameliorate neurological deficits and brain damage after I/R injury. Leaking amount of Evans Blue was reduced by XNJ, and the expression of tight junction protein, occludin and ZO-1 was also up-regulated by XNJ, which showed a role of protection on BBB disruption. The expression of NLRP3 was inhibited after exposure of XNJ, which was associated with inhibition of the inflammatory response. In summary, XNJ could suppress NLRP3 inflammasomes and improve BBB disruption and brain damage in rats after cerebral I/R injury, which provided a beneficial insight to further explore XNJ.

文摘Objectives:To investigate the effectiveness and safety of Xingnaojing Injection(XNJ,醒脑静注射液)compared with naloxone for the treatment of acute alcohol intoxication(AAI),and provide the latest evidence through evidence-based approach.Methods:Seven electro-databases including Pub Med,EMBASE,Cochrane Central Register of Controlled Trials,Chinese National Knowledge Infrastructure Databases,Chinese Biomedical Literature Database,Chinese Science and Technology Periodical Database(VIP)and Wanfang Database were searched from the inception to January 2018.Randomized controlled trials(RCTs)comparing XNJ with naloxone for patients with AAI and reporting at least one of the below outcomes were included:patients’conscious recovery time,stay length in emergency department,disappearance time of the ataxia symptom,the severity of the symptoms,the blood alcohol content as wel as the adverse events.Methodological quality of included trials was assessed using the risk of bias tool which recommended by the Cochrane Col aboration.Meta-analysis was conducted by Review Manager 5.3 software.Results:Total y 141 trials with 13,901 patients were included in this review,al of them were assessed as unclear or high risk of bias.Results showed that on the basis of routine therapy,standard dose XNJ(10–20 m L)may have similar results with naloxone on the recovery time of consciousness(MD 12 min,95%CI 7.2–17.4 min)and disappearance time of symptoms(MD 6 min,95%CI–13.8–25.8 min)for patients with AAI.Larger dose of XNJ Injection(21–40 m L)may speed up the time(almost 1 h earlier).Combination of XNJ and naloxone seemed superior to the naloxone alone for al the relevant outcomes.The average difference of time in consciousness recovery was 2 h and the number of AAI patients whose consciousness recovery within 1 h was above 50%the combination group than in the control group(RR 1.42,95%CI 1.29 to 1.56).No severe adverse events or adverse reactions of XNJ were reported in the included trials.Conclusions:Low quality of evidence showed XNJ may have equal effect as naloxone and may achieve better effect as add-on intervention with naloxone for patients with AAI.We failed to evaluate the safety of XNJ Injection due to the insufficient evidence in this review.

文摘Objective: To elucidate the action mechanism of Xingnaojing Injection (醒脑静注射液, XNJI) for sepsis, and to target screen the potential bioactive ingredients. Methods: An integrated protocol that combines in silico target screen (molecular docking) and database mapping was employed to find the potential inhibitors from XNJI for the sepsis-related targets and to establish the compound-target (C-T) interaction network. The XNJI's bioactive components database was investigated and the sepsis-associated targets were comprehensively constructed; the 3D structure of adenosine receptor A2a and 5-1ipoxygenase proteins were established and evaluated with homology modeling method; system network pharmacology for sepsis treatment was studied between the bioactive ingredients and the sepsis targets using computational biology methods to distinguish inhibitors from non inhibitors for the selected sepsis-related targets and C-T network construction. Results: Multiple bioactive compounds in the XNJI were found to interact with multiple sepsis targets. The 32 bioactive ingredients were generated from XNJI in pharmacological system, and 21 potential targets were predicted to the sepsis disease; the biological activities for some potential inhibitors had been experimentally confirmed, highlighting the reliability of in silico target screen. Further integrated C-T network showed that these bioactive components together probably display synergistic action for sepsis treatment. Conclusions: The uncovered mechanism may offer a superior insight for understanding the theory of the Chinese herbal medicine for combating sepsis. Moreover, the potential inhibitors for the sepsis-related targets may provide a good source to find new lead compounds against sepsis disease.
