RESUMO
The pathogenesis of hepatocellular carcinoma is complex and has not been fully clarified. KLF4, also known as gut-enriched Kruppel-like factor (GKLF), plays the dual regulatory role of tumor suppressor and tumor promoter. KLF4 plays an anti-cancer role in liver cancer. This article introduces the biological function and regulatory mechanism of KLF4 in the progression of liver cancer, and research on the mechanism of action of KLF4 in liver cancer is expected to provide new ideas for targeted therapy and prognosis monitoring of liver cancer.

RESUMO
Objective@#To investigate the expressions of serum miRNA-126 (miR-126) and miRNA-30c (miR-30c) in patients with pancreatic cancer, and to analyze the relationship with the occurrence of pancreatic cancer as well as the diagnostic value.@*Methods@#A total of 110 patients with pancreatic cancer diagnosed at the 928th Hospital of the Joint Service Support Force of PLA from January 2014 to December 2018 were selected, and 110 healthy people were also selected as the control group. The expression levels of serum miR-126 and miR-30c of 110 patients and the healthy controls were detected by using real-time quantitative polymerase chain reaction (qRT-PCR), and their relationship with clinicopathological features of pancreatic cancer was analyzed.@*Results@#The levels of serum miR-126 and miR-30c in pancreatic cancer group were lower than those in the healthy control group (0.43±0.12 vs. 1.02±0.27, t = 19.394, P < 0.01; 0.52±0.17 vs. 1.04±0.31, t = 15.426, P < 0.01). There was a positive correlation between levels of serum miR-126 and miR-30c in patients with pancreatic cancer (r = 0.399, P < 0.01). Expression levels of serum miR-126 and miR-30c were not correlated with age, gender and body mass index (BMI) of pancreatic cancer patients (all P > 0.05), but related with tumor size, differentiation degree, TNM stage and lymph node metastasis (all P < 0.05). High expression levels of serum miR-126 and miR-30c were protective factors for pancreatic cancer (all P < 0.05), while smoking, drinking and gallstones were risk factors for pancreatic cancer (all P < 0.05). The area under the curve of combined detection of serum miR-126 and miR-30c for diagnosis of pancreatic cancer was 0.906, the sensitivity was 90.80%, and the specificity was 82.20%.@*Conclusions@#The expression levels of serum miR-126 and miR-30c in patients with pancreatic cancer are low. Both of them may be involved in the occurrence and development of pancreatic cancer, and may be used as early diagnostic markers of pancreatic cancer.
RESUMO
Objective To compare the prognosis of ST elevation acute myocardial infarction(STEMI) of delayed emergency per‐cutaneous coronary intervention(PCI) and elective PCI following the thrombolysis with reteplase ,and to investigate the clinic value of the former solution .Methods One hundred and twenty STEMI patients were reviewed retrospectively and were divided into 2 groups according to PCI .Eighty two cases were divided into emergency group :thrombolysis with reteplase offered within 6h was followed by elective PCI;38 cases were divided into delayed group:PCI was done after 12-24 h after ATEMI′occurring .The clini‐cal features and CTG changes were recorded ,TIMI class of IRA was conducted before and after PCI ,and their prognosis were com‐pared .Results There was no statistical differences in the class of thrombolysis of myocardial infarction(Class 0 -1 ,2 -3) of in‐farction relative artery (IRA)(4 .88% ,95 .12% vs .5 .26% ,94 .74% ) after PCI(P>0 .05) .There was no statistical difference in LVEF ,LVEDVI and LVESVI 3 months after attack between two groups(P>0 .05) .There was statistical difference in the severe cardiac failure and malignancy arrhythmia between two groups(P0 .05) .Conclusion Delayed emergency PCI to remove the ob‐struction in the coronary artery has no significant difference with elective PCI following thrombolysis in the incidence of composite end point events in STEMI .
RESUMO
Objective To investigate the subjective life quality of hospitalized children and analyze its influencing factors for improving their life quality.Methods 48 hospitalized children who were admitted between May to August 2011 were investigated in convenience using inventory of subjective life quality (ISLQ).Results Patients investigated had a higher score than the national norm on Family Life Dimension.The satisfaction level of 20％ ～ 30％ children were below the average on Family Life and other eight dimensions,the cognitive components of 16 cases (33.3％) and emotional component of 11 cases (22.9％) were below the average.15 cases (31.3％) were not satisfied with their subjective quality of life.Female patients had higher scores than male patients on peer exchanges,body feelings and subjective quality of life satisfaction; the satisfaction level of experience depression for rural children was lower than urban children.Conclusions The subjective life quality of vast majority of hospitalized children is about the general level,but some patients still experience serious anxiety,depression and other negative psychological emotion.Nurses should guide the patients positively and specially,considering the influence of their gender and living places while providing caring.Based on the health education of patients and their family,we promote them to face the disease.
