Objective:To investigate the mechanism by which curcumin activates the PINK1/Parkin pathway to enhance mitophagy and ameliorate endothelial cell damage induced by oxygen-glucose deprivation/reperfusion(OGD/R).Methods:An OGD/R injury model was established in mouse brain microvascular endothelial cells(BMECs).En-dothelial cells were treated with different concentrations of curcumin.The effects of curcumin on mitophagy in BMECs were assessed using immunofluorescence and transmission electron microscopy.Cell proliferation,injury,and barrier integrity were evaluated using a Cell Counting Kit-8(CCK-8),lactate dehydrogenase(LDH)assay,and transendothe-lial electrical resistance(TEER)measurement,respectively.Western Blot was used to detect the effects of curcumin on the expression of PINK1/Parkin pathway proteins(LC-3 Ⅱ/Ⅰ,PINK1,Parkin and p62).Additionally,cells were co-treated with Mdivi-1 to further confirm the role of mitophagy in curcumin's protective effects against OGD/R injury.Results:Curcumin treatment significantly promoted mitophagy,increased the expression of LC-3 Ⅱ/Ⅰ,PINK1,and Par-kin proteins(P＜0.001),and decreased the expression of p62 protein(P＜0.001).In the OGD/R model,curcumin significantly enhanced cell proliferation rates(P＜0.001),reduced LDH release(P＜0.001),and improved TEER values(P＜0.001).However,these protective effects of curcumin were reversed by the mitophagy inhibitor Mdivi-1.Conclusion:Curcumin effectively alleviates cell damage in BMECs under OGD/R conditions by enhancing mitophagy through the activation of the PINK1/Parkin pathway.

Objective To explore effect of rehabilitation training on deglutition disorders of children with cerebral palsy . Methods Twenty-seven children patients from January to June in 2013 were set as control group and thirty-one patients from July 2013 to January 2014 as experiment group. The children in the control group were treated with tube-feeding combined with spoon feeding and bottle-feeding by professional nurse. Children in the experiment group were treated with oral rehabilitation training by professional therapists and nurses apart from the same feeding as in the control group. The two groups were compared in terms of effect of deglutition within 4 weeks, time and rate of removing the stomach tube. Results The recovery of deglutition function in the experiment group was much better than that in the control group , the total effective rate and rate of removing the stomach tube within 3 months were higher and the intubation duration was significantly lower as compared with those of the control group (P < 0.01). Conclusion Rehabilitation training can improve the recovery of deglutition disorders, improve active feeding ability of children with cerebral palsy, shorten time of tube feeding and improve their life quality.

Objective To observe the efficacy of vitamin B2 combined with smecta in the treatment of infant diaper rash. Methods Fifty-nine infants were divided into the treatment group with 32 infants and the control group with 27 infants. The treatment group was given vitamin B2 combined with smecta treatment and the control group was given zinc oxide treatment. The efficacy was observed after 7 days of treatment. Results The remarkably effective rate of the treatment group was 87.5% and the total effective rate was 96.9%. The remarkably effective rate of the control group was 22.2% and the total effective rate was 66.7%. Statistical analysis showed that the two groups were significantly dif-ferent in the efficacy (P<0.01). Conclusion Vitamin B2 combined with smecta is a safe and reliable treatment scheme for infant diaper rash.
