Background:Gastric cancer is a common gastrointestinal malignancy. The detection rate of early gastric cancer is still low in China,and some gastric cancer patients visit the hospital due to acute disease,such as gastric perforation. Aims:To investigate the influence of acute disease on long-term prognosis in gastric cancer patients. Methods:A total of 318 patients with gastric cancer from Jan. 2009 to Jan. 2015 at Shaoxing People’s Hospital were enrolled,and were divided into acute disease group and non-acute disease group. Clinicopathological characteristics were analyzed. Patients were followed up,and survival rate was compared between the two groups. Results:Fifty-three(16. 7% )patients had acute disease,and the remaining 265(83. 3% )patients were without acute disease. Compared with non-acute disease group, percentage of TNM Ⅳ stage was significantly increased(P < 0. 05),and percentage of radical surgery was significantly decreased in acute disease group(P < 0. 05). Kaplan-Meier assay showed that survival rate in acute disease group was significantly decreased when compared with non-acute disease group( P < 0. 05). After adjusting the TNM stage and surgical treatment,no significant difference in survival rate was found between the two groups. Conclusions:Gastric cancer patients with acute disease have lower survival rate. Acute disease may be not an independent prognostic factor, higher TNM stage and lower proportion of radical surgery are the main reasons for poor prognosis in gastric cancer patients with acute disease.

Pancreatic acinar cell death modality is a significant factor which determines the course and prognosis of acute pancreatitis (AP).The severity of AP is positively correlated with acinar necrosis,while negatively correlated with acinar apoptosis.Adenosine triphosphate (ATP) level is the key to control the manner of death,and acts as a switch during the conversion of necrosis and apoptosis in a variety of pathophysiological settings:low levels of ATP can accelerate cell necrosis and high levels of ATP might promote apoptosis.Hypoxia inducible factor 1 (HIF-1) is a highly expressed transcription factor in anoxic conditions which can effectively regulate cell energy metabolism and play an important role in regulating cell death and inflammatory injury.Therefore,this review aimed to provide a reference about better understanding of the pathogenesis and new therapeutic targets of HIF-1 in AP.

Recurrent pancreatitis ( RP) can be further divided into two items , including recurrent acute pancreatitis ( RAP ) and recurrent chronic pancreatitis ( RCP ) .In recent years, with the rising incidence of pancreatitis , the incidence of RP has also been increased .During the development of pancre-atic diseases, RP may serve as a transitional disease .Thus, this article reviewed the latest research progress on RP in order to discuss its role in the development of the related pancreatic di-seases and the effects on clinical prognosis , and provide a refe-rence for preventing and treating RP and even cancer .

OBJECTIVETo study the expressions of Notch1-4 gene in human keloid-derived mesenchymal-like stem cells, and to explore the Notch signaling pathway's role in the formation of keloid.

METHODSKeloid samples were collected to harvest human keloid-derived mesenchymal-like stem cells through two-step enzymatic dissociation method. By flow cytometry, cell phenotype of primary and P3 generation were analyzed. By immunocytochemistry, the expressions of Oct4, vimentin and CK19 were examined. Keloid-derived mesenchymal-like stem cells were induced into osteoblasts in vitro and calcium deposition was detected by Alizarin red S stain. Realtime polymerase chain reaction (RT-PCR) was used to detect the expressions of Notch1-4 mRNA in keloid-derived mesenchymal-like stem cells.

RESULTSFlow cytometry showed that keloid-derived mesenchymal-like stem cells of primary and P3 generation highly expressed CD29, CD44, CD90 from the typical MSC phenotype marker, but they failed to express HSC phenotype markers, such as CD34 and CD45. The results of immunocytochemistry showed that Oct4 from pluripotent stem cell markers and vimentin from mesenchymal cell markers was positive and CK19 from epithelial cell markers was negative. After induced differentiation into osteoblasts in vitro after 21 day, calcium nodules could be seen clearly; Notch1-4 gene were expressed in keloid-derived mesenchymal-like stem cells through RT-PCR. The relative quantitative of Notch2, Notch3 gene were higher than Notch1, Notch4 gene (P < 0.05).

CONCLUSIONSThe expression difference of different subtypes from Notch gene in human keloid-derived mesenchymal-like stem ceils may be related to self-renewal, proliferation, differentiation, and participate in the formation of keloid.
