Objective:To detect the expression of microchromosome maintenance protein 4 (MCM4) in pancreatic ductal adenocarcinoma, and to explore the clinical prognosis of MCM4 and pancreatic ductal adenocarcinoma. To explore the possibility of MCM4 as a potential biomarker for pancreatic ductal adenocarcinoma.Methods:The mRNA level of MCM4 in pancreatic ductal adenocarcinoma and normal tissues adjacent to the cancer was analyzed by bioinformatics methods, and the relationship between its expression and the survival rate of patients with pancreatic ductal adenocarcinoma was analyzed. The clinicopathological data of 76 patients with pancreatic ductal adenocarcinoma who underwent surgical treatment were retrospectively analyzed. Immunohistochemical method was used to detect the expression level of MCM4 protein in pancreatic ductal adenocarcinoma tissue and normal tissues adjacent to the cancer, and to analyze its relationship with clinicopathological characteristics of patients with pancreatic ductal adenocarcinoma.Results:The results of bioinformatics analysis showed that MCM4 mRNA was significantly highly expressed in pancreatic ductal adenocarcinoma tissue, and was significantly correlated with the overall survival rate and disease-free survival rate of patients (all P<0.05). Immunohistochemical results showed that the expression of MCM4 in pancreatic ductal adenocarcinoma tissue was significantly higher than that in normal tissues adjacent to the cancer. The high expression of MCM4 in pancreatic ductal adenocarcinoma tissue was related to tumor size ( P=0.038), but not related to age, gender, and tumor grade (all P>0.05). Conclusions:MCM4 is highly expressed in pancreatic ductal adenocarcinoma tissues and indicates a poor prognosis, and its expression level is related to the tumor stage of pancreatic ductal adenocarcinoma. MCM4 may serve as a new potential biomarker for pancreatic ductal adenocarcinoma.

Objective To observe the influence of recombinant human brain natriuretic peptide(rhBNP)on serum HMGB1 levels in canines'acute renal injury induced by endotoxin and explore its protective role of rhBNP in protecting canines'kidney against acute renal injury.Methods A total of 20 healthy dogs were randomly divided into four groups:blank group,sepsis shock group,low-dose intervention group and high dose intervention group, and there were 5 rats in each group.After establishing the model of canines'sepsis shock induced by endotoxin,15 canines (besides blank group)were randomly divided into 3 groups.As follows,5 μg/kg rhBNP was given to the low-dose intervention group,10μg/kg rhBNP was given to the high-dose intervention group.But nothing was given to control group.Systemic vascular resistance index(SVRI)at 0 h,2 h,4 h,8 h,12 h were observed by PICCO instrument.High mobility group box 1 protein (HMGB-1)and creatinine(CR)in blood samples at each time point were detected.After 12 hours,kidney samples were taken for histological examination.Results The results revealed that some renal tubulars epithelial cell were swelled,some epithelial cells were atrophy and interstitial cells swelled in control group under the light microscope.Kidney pathology score was 2-3.But these changes were improved in low-and high-dose intervention groups,and there were no significant difference in the latter two groups,kidney of both groups pathology score were 1-2.Compared with control group at the same point,CR of blood serum were significantly decreased in low-dose intervention group at 8 h,12 h(P<0.01), and high-dose intervention group significantly decreased at 4 h,8 h,12 h(P<0.01).Compared with low-dose intervention group at the same point,CR of blood serum in high-dose intervention group were significantly decreased at 4 h,8 h,12 h (P<0.05).Compared with control group at the same point, systemic vascular resistance index(SVRI)were significantly decreased in low-dose intervention group at 2 h (P<0.01 ),but significantly decreased in high-dose intervention group at 2 h and 4 h (P<0.01).Compared with low-dose intervention group at the same point,SVRI in high-dose intervention group were significantly decreased at 4 h (P<0.05 ).Compared with control group at the same point,the expressions of high mobility group box 1 protein (HMGB-1)in blood serum in low- and high-dose intervention groups were significantly decreased(P<0.01);Compared with low-dose intervention group at the same point,the expressions of HMGB-1 in blood serum in high-dose intervention group were significantly decreased (P<0.05).Conclusion rhBNP can effectively reduce canine kidney tissue injury mediated by endotoxin and improve kidney function,reduce SVRI,and its therapeutic effect of rhBNP was in a dose-response relationship.rhBNP can effectively reduce HMGB-1 levels in blood serum of sepsis shock canines,which may be associated with the decrease of late inflammatory factor HMGB1.

Objective To observe the effect of healthy side limb training on stroke patients with hemiplegia.Methods 160 stroke patients with hemiplegia were divided into the observation group and control group.All patients in both groups were given routine rehabilitation,but the patients in the observation group were given the healthy side limb training.All patients were evaluated with Brunnstrom grades,Bathel Index(BI),Hamilton Depression Scale(HAMD)and the function of healthy side hand before and 5 months after treatment.Results After treatment,the function of trouble side limb of patients in both groups increased significantly compared with those before treatment.The scores of Brunnstrom grades,BI,HAMD and the function of healthy side hand of patients in the observation group increased significantly compared with those in the control group(P<0.01).Conclusion The healthy side limb training may improve the function of trouble side limb,activities of daily living and depression of stroke patients with hemiplegia.
