Spinal cord injury is a kind of central nervous system injury disease caused by trauma. It was found that the up-regulation of autophagy after spinal cord injury could promote the repair of spinal cord injury. Under the condition of stress, autophagy can reduce the number of misfolded proteins and damaged organelles in cells to maintain the stability of intracellular environment. Chinese medicine with Huoxue Quyu Tongluo (against stasis obstructing meridian) efficacy has attracted much attention in the treatment of spinal cord injury, which may associate with the role of regulation of autophagy.

Objective To observe the effects of penehyclidine hydrochloride(PHC)on lipopo-lysaccharide-induced neonatal cardiomyocyte damage.Methods After the primary cardiomyocytes culture of neonatal rat on postnatal day 1,the myocytes were randomly divided into 4 groups:the control group,the lipopolysaccharide(LPS)group,the low dosage PHC pretreatment group and high dosage PHC pretreatment group.Activities of myocardial enzymes and cardiac troponin and cell survival rate were measured.Expres-sion of NF-Κb(p65)and IκB-α(NF-κB inhibitor)phosphorylation were assessed using Western blot.Re-sults Compared with the control group,activities of myocardial enzymes and cardiac troponin in the LPS group were elevated but the survival rate were down-regulated.All these effects were reversed in the PHC pretreatment group.Results of Western blot showed that phosphorylation of IκB-αand p65 expression were up-regulated in the LPS group.In the PHC pretreatment group,phosphorylation of IκB-αand p65 expres-sion were down-regulated.Conclusion Penehyclidine hydrochloride can inhibit lipopolysaccharide-in-duced neonatal cardiomyocyte damage and the down-regulation of NF-κB activity might be involved.
