Objective To compare the short term outcome of PPH with Milligan Morgan hameorrhoidectomy. MethodsNinety cases of Ⅲ ? Ⅳ ?degree hemorrhoids admitted for surgical treatment were randomly assigned to PPH ( n =45) or Milligan Morgan( n =45).ResultsThe difference was statistically significant between the two groups in terms of pain index ?operative time?length of hospital stay? time required for returning to normal activity and hospital fee. The above factors were found more favourable in PPH group, with no severe complications developed in neither of the two groups.The symptom improvement rate was 88% in PPH group and 81% in Milligan group.ConclusionPPH is a safe and effective procedure for Ⅲ ? Ⅳ ?hemorrhoids and its shorter term outcome is better than Milligan Morgan procedure.

Objective To study the relationship between level of plasma glucose and cognitive function in patients with Parkinson's disease.Methods Two hundred PD patients were assessed cognitive function using Mini-Mental State Examination (MMSE),Montreal Cognitive Assessment (MoCA),Wechsler Intelligence Scale and Wechsler Memory Scale.The patients were divided into cognitive normal group (n=91) and cognitive impairment group (n=109).One hundred twenty-six normal subjects were enrolled as control group (n=126).The levels of fasting plasma glucose (FPG),postprandial plasma glucose (2hPPG),glycosylated hemoglobin (HbAlc) and the prevalence of diabetes mellitus were compared among the groups.The effect of blood glucose level on the cognitive function of PD patients was analyzed by Binary Logistic Regression.Results The levels of FPG,HbAlc and the prevalence of diabetes mellitus [5.19 (0.72),5.7％ (0.5％),14％] were significantly higher than those in the normal control group [4.85(0.79),5.6％ (0.5％),6％] (P＜0.05).The levels of FPG in PD patients with cognitive impairment [5.21 (1.32)] was significantly higher than that in PD patients with cognitive normal group [4.81 (0.95)] (P＜0.05).Although 2hPPG and HbAlc increased slightly in PD patients with cognitive impairment,the difference did not reach an significant level (P＞0.05).Binary Logistic Regression analysis showed that FPG(OR:1.764;95％ CI:0.06-3.244;P=0.068) was not associated with the impaired cognitive function in PD patients.Conclusion The present study has not revealed an association between the incidence of cognitive impairment in patients with PD and plasma glucose level although high plasma glucose may be a high risk factor for PD patients.

Objective     To explore the role of versican (VCAN) in ESCC prognosis based on bioinformatics data. Methods    First, three RNA microarray datasets of ESCC were downloaded from GEO database, which were then integrated and used to explore differentially expressed genes (DEGs). The subsequent analysis was conducted based on the results of these DEGs: (1) The STRING database was used to construct a protein-protein interaction (PPI) network;(2) molecular complex detection software was used to analyze the modules of the PPI network, of which the most significant modules were chosen, and hub genes were the genes included in the chosen modules; (3) high-throughput RNA sequencing data from TCGA and GTEx databases were used to verify the expression of these hub genes to confirm whether they were differentially expressed; (4) the survival curve analysis of confirmed DEGs was conducted to select genes that had significant influence on the survival of ESCC; (5) TIMER database was used to analyze the relationship between the gene expression of VCAN and the abundance of tumor-infiltrating immune cells (TIICs) and gene markers in these cells; (6) Targetscan and miRDB software were used to predict the miRNAs that could regulate VCAN, and Cytoscape software was used to construct the regulatory network. Results    A total of 630 DEGs and 32 hub genes were found, of which VCAN was an up-regulated DEG, and high expression of VCAN was significantly associated with poor prognosis of ESCC. Moreover, VCAN could also play a role in the immune microenvironment of ESCC, which was mainly manifested by a significant positive correlation between the abundance of VCAN and the abundance of M2 macrophages gene markers, some of which had been reported to be associated with poor prognosis of ESCC. Finally, we also found that VCAN could be regulated by 15 miRNAs in ESCC, some of which had been reported to be associated with ESCC prognosis. Conclusion    This study provides direct and indirect comprehensive evidence for the role of VCAN in ESCC prognosis. The direct evidence is that the survival curve shows that highly expressed VCAN is significantly associated with the poor prognosis of ESCC, and the indirect evidence is that VCAN is positively related to some markers which indicate poor prognosis in the ESCC immune microenvironment, and VCAN can be regulated by some prognostic miRNAs in ESCC.
