prognosis of patients with acute upper gastrointestinal bleeding (AUGIB). Methods A total of 130 patients with AUGIB in our hospital were enrolled in this study from August 2014 to August 2016 . Three kinds of scoring systems including Rockall, Blatchford and AIMS65 were used to evaluate the risk classification of the patients. Patients were followed up for 2 months. The incidence rates of re-bleeding and death within 2 months after admission were observed. Data of prognosis in patients with AUGIB were compared between the three scoring systems in the prognosis of patients with AUGIB, including the risk classification and the prediction accuracy of re-bleeding and death. Results There were no significant differences in the re-bleeding rate and fatality rate between the groups divided by Rockall and Blatchford scoring systems ( P>0.05). According to the grouping results of AIMS65 scoring system, the re-bleeding rate of low-risk group was lower than that in high risk group (1.45%vs. 13.11%, P=0.01), but there was no significant difference in fatality rate between the two groups (P>0.05). The values of area under the curve (AUC) of predicting re-bleeding rates by using Rockall, Blatchford and AIMS65 scoring systems were 0.6258, 0.6910, and 0.7241, and the values of AUC of predicting fatality rates were 0.7031, 0.7969, and 0.7031 by using receiver operating characteristic curve (ROC) analysis. There were no significant differences between them (P>0.05). The values of AUC of predicting re-bleeding rates by using the risk grading calculation by Rockall, Blatchford and AIMS65 scoring systems were 0.6189, 0.6139 and 0.7254 (P>0.05). But the values of AUC of predicting fatality rates were 0.6211, 0.6641 and 0.7695 (P<0.01). Conclusion The operation method of AIMS65 scoring system is simple and convenient, which is applicable to a wide range of patients with AUGIB. In the prediction of re-bleeding and mortality, AIMS65 scoring system has high accuracy and stability, which is worthy of promoting in clinical application.

Objective:To study the influence of morphine on the expression of nestin in the ependymal epithelia,central gray and hippocampal formations in mice.Methods:Twenty health mice were evenly randomized into control group and experiment group.Mice in the control group were injected with normal saline(0.1 ml daily)and those in the experimental group were injected with morphine (0.1 ml,1 mg daily).Thirty days later,the mice brain samples were harvested and made into paraffin sections.Immumohistochemical ABC technique was used to observe the expression of nestin under light microscope.The images were analyzed with the image analytical system.Results:In the control group,the ependymal epithelia,the central gray,the periventricular gray substances and the hippocampal formations had weak expression of the nestin,with a mean gray scale of 150.98?13.31;there were 5 kinds of nestin-positive cells:(1) the basal cells of ependymal epithelium,(2)cells distributed in the periventricular gray substance and the deep lamella of central gray, (3)cells distributed in the superficial lamella of central gray,the subiculum,the parahippocampal gyrus and the cortex inⅡ,Ⅲlayers of the entorhinal area,(4)cells frequently seen in the rectum of midbrain and the subiculum,and(5)cells distributed in the tectum of midhrain,the hippocampus,gyrus dentatus,parahippocampal gyrus and the cortex in V layer of the entorhinal area;the density of nestin in the subiculum and entorhinal area was(7.20?1.23)mm~2.In the experiment group,the ependymal epithelia,the central gray,the periventricular gray substances and the hippocampal formations had positive expression of the nestin,with the mean gray scale being 133.03?22.28;the density of the above-mentioned 5 kinds of cells increased;the density of nestin in the subiculum and entorhinal area was(10.50?1.43)mm~2.The mean value of gray scale and nestin-positive neurons were significantly different between the 2 groups (P

AIM: To observe the expression of β-catenin in patients with chronic myeloid leukemia (CML) at different disease phases, and to analyze the relationship between BCR-ABL and cytogenetic response to imatinib mesylate. METHODS: RT-PCR and Western blotting were used to detect β-catenin mRNA and protein expression in bone marrow mononuclear cells (BMMNCs) from 99 patients with CML. The association with BCR-ABL and BCR-ABL fusion was determined by FISH in 94 patients after one year treatment with imatinib mesylate, and the relationship between β-catenin and cytogenetic response to imatinib mesylate was analyzed. RESULTS: The expression of β-catenin was increased significantly in patients with blast crisis and accelerated phase (P<0.01), while the expression of β-catenin between normal person and chronic phase of CML patients was not statistically different (P>0.05). No significant relation between β-catenin and BCR-ABL expression (r=0.314, P>0.05) was observed. The expression of β-catenin was increased significantly in the patients who did not reach main cytogenetic remission (P<0.01). CONCLUSION: The patients in progression phases of CML over-express β-catenin. The expression of β-catenin is not significantly related to BCR-ABL expression, but related to the therapeutic response of imatinib. Beta-catenin may be involved in the mechanism of CML progression and could be used as a new therapeutic target.

In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.

BACKGROUND:Gastric cancer stem cels involved in the neoadjuvant chemotherapy and conventional treatment are closely associated with relapse of gastric cancer. However, this conclusion has not yet been confirmed.
OBJECTIVE:To investigate the effects of gastric cancer stem cels in tumor invasion and metastasis and its effect on angiogenesis ability.
METHODS:We prepared nude mouse models of gastric cancer to isolate and culture gastric cancer stem cels. Harvested gastric cancer stem cels were detected in cel scratch test, ring test, inhibition rate test, cel migration test and tumorigenicity test.
RESULTS AND CONCLUSION:After 7 days of culture, the cels exhibited adherent growth but a lack of regularity that most cels were in a tadpole shape. In the cel scratch test, the scratch width was significantly different at 0 and 24 hours (P < 0.05). Under an inverted microscope, the cels were found to form a ring in the ring test. The 50% inhibiting concentration of gastric cancer stem cels induced by oxaliplatin was significantly lower than that induced by 5-fluorouracil (P < 0.05). The number of cels passing through the basilar membrane was significantly increased after cel migration (P < 0.05). After implantation of gastric cancer stem cels, the gastric tissue quality was significantly higher than that in normal nude mice of gastric cancer (P < 0.05). These findings indicate that gastric cancer stem cels responsible for tumor invasion and migration have stronger angiogenesis ability.
