In recent years, remote ischemic preconditioning is found as a novel way to protect the brain, which may be achieved through nerve pathways, humoral factors or nerve-humoral interaction. The molecular mechanisms for the protection might be related to mitochondria ATP-sensitive potassium channel, mitogen-activated protection kinase, mammalian target of rapamycin, including nitric oxide synthase and cannabinoid receptors. The aim of this review is to explain the mechanism of action of remote ischemic preconditioning on brain protection, as well as the possible direction of clinical application.

Diabetic peripheral neuropathy is a common complication of diabetes mellitus,can occur in some patients with painful diabetic peripheral neuropathy.The occurrence of PDPN is related to many factors,such as long term severe hyperglycemia and metabolic disorders,deficiency of neurotrophic factors, disorder of microcirculation,increase of oxygen free radicals in oxidative stress and disorder of immune func-tion.Mitogen activated protein kinase (MAPK)is a kind of serine /tyrosine protein kinase ,which can widely expressed in cell,and can be involved in the pathophysiological process of stress,inflammation,cell cycle and apoptosis through increased nuclear transcription factors.P38MAPK signaling pathway is an im-portant branch of the MAPK,this overview focuses on the research progress of p38MAPK signaling pathway in the pathogenesis of PDPN.

Objective To evaluate the effect of oral health instructions in nursing of marsupialized jaw cysts. Methods 46 patients with cysts of jaw were divided randomly into two groups (education group and control), 23 in each. In addition of normal nursing processes in both groups, patients in education group were offered more oral health instructions, such as pathogenesis of jaw cysts, mechanism of marsupialization, wear and clean of a cyst plug, and oral hygiene maintenance. 12 months later, compliance, satisfaction, treatment effect and oral hygiene condition of the patients in the two groups were studied and compared. Results 100%of patients in the education group could return to clinical visits on time and 96%of patients did cyst rinsing after every meal, which were significantly higher (χ2=6.9, P<0.05) than in the control (74% and 70% respectively). Patients′satisfaction in the two groups were also significantly different (χ2=9.109,P<0.05). Patients in the education group were much more satisfied with the treatment procedures than control. The treatment effect of the cyst in the education group [good (83%), moderate (17%), not so good (0%)] was significantly (χ2=7.793, P<0.05) better than control (good (43%), moderate (52%), not so good (5%)]. The secondary infection rates in the two groups were similar (χ2=1.022, P>0.05). Oral hygiene condition of patients in the education group was better than control in Debris Index (χ2=9.576, P < 0.05) and Plaque Index (χ2=8.212, P < 0.05). Conclusions Oral health instructions played positive role in improving patients′ compliance, degree of satisfaction, treatment effect and oral hygiene condition in patients with jaw cysts.

Objective Previous study found TGF-βpathway might be the molecular pathway influencing the prognosis of colo-rectal cancer, while it was uncertain whether Chinese population is associated with the disease.The article was to evaluate the genetic factors associated with prognosis in colorectal cancer. Methods 52 cases patients with colorectal cancer were followed-up for 36 months in our hospitals from January 2013 to August 2014.Their DNAs were extracted and stored and gene typing were carried out in 5 candidate genes to detect the association between SNPs and the prognosis in colorectal cancer. Results The results showed that within the TGF-βsignaling pathway, after adjusting for Bonferroni multiple testing, allele A of SNP rs10749971 located in gene POU2AF1 was associated with the recurrence of patients with stage III disease under additive and recessive genetic models ( HR =1.968, P=0.004;HR=2.174, P=0.010).Allele C of SNP rs961253 in the gene BMP2 could increase the recurrence risk (HR=1.992, P=0.005) and the death risk (HR=3.161, P=0.007) of patients with stage III disease under recessive genetic models.Allele A of SNP rs4464148 in SMAD7 gene could significantly decrease the death risk of patients with stage II and III colorectal cancer under dominant genetic model (HR=0.382, P=0.017;HR=0.230, P=0.006).In addition, accumulated effects of several adverse genes showed gene high risk group could increase the risk of death for patients with stage III colorectal cancer significantly ( HR=15.512, P=0.036;95%CI:1.611-149.360). Conclusion In different genetic models, SNP locus mutation within gene POU2AF1, BMP2 and SMAD7 on TGF-βpathway was associated with the prognosis of patients with colorectal cancer.With the increase of the number of unfavorable genes, the death risk increases accordingly.
