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.

The present paper intends to discuss the antioxidant and tyrosinase inhibition effect of solanesol from three aspects of ultraviolet radiation and free radical scavenging. The paper makes a survey on diurnal variation rule of the minimum ultraviolet transmittance and ultraviolet transmittance of solanesol, hydroxyl (OH) free radical scavenging method of Smirnoff reaction system model, superoxide anion O2- free radical scavenging method of pyrogallol autoxidation, and the inhibitory effect of solanesol on tyrosinase activity by enzyme kinetic method. The experiment results showed that solanesol could effectively scavenge lipid radicals to block lipid peroxidation, and inhibit effects on tyrosinase. Solanesol is a natural extract which could be used to prevent senile atrophy of human skin and senile plaque.

AIM: To investigate the effect of ischemic preconditioning (IP) on myocardial Bcl-2 expression and mitochondrial structure during heart valve replacement surgery under cardiopulmonary bypass. METHODS: Fifty-four patients were prospectively randomized to receive or not ischemic preconditioning (IP) before cold cardioplegic arrest. Ischemic preconditioning in the IP patients (n=22) was induced by a single 2-min ischemia followed by 3-min reperfusion just before aortic clamping and cold crystalloid cardioplegia for myocardial protection. The control group (n=32) received no ischemic preconditioning before cold cardioplegic arrest. The levels of ejection fraction (EF), fractional shortening(FS) and stroke volume (SV) in both groups were measured and compared. troponin T (c-TnT) level, Bcl-2 protein expression and microscopic changes of myocardial mitochondrial structure were recorded for each group before and after surgery. RESULTS: The level of EF, FS and SV in IP group was higher than those in control group (P<0.05). No significant difference in preoperative c-TnT levels between two groups was observed. The level of c-TnT in IP group was lower than that in control group and with a declining trend over time of 6 h, 24 h, 48 h, 72 h and 5 d after surgery, respectively. The preoperative positive unit of Bcl-2 expression between two groups showed no statistical difference (P> 0.05). Postoperatively, the positive unit of Bcl-2 expression in IP group was 19.85±5.88, significantly increased as compared to the preoperative value (P<0.05). In control group, the positive unit of Bcl-2 expression was 14.17±3.39, showed no statistically significant difference to the preoperative value (P>0.05). Postoperative Bcl-2 expression between two groups showed a significant difference (P<0.05). In the control group, microscopic observation revealed swollen mitochondrion, with a hardly visible or disrupted membrane for some mitochondrion;mitochondrial crista were obviously dissolved and loose with a large number of vacuoles formation. However in IP group, myocardial mitochondrion appeared with intact membrane, concentrated mitochondrial cristae with high electron density and no vacuoles formation was observed. CONCLUSION: IP may up-regulate the expression of myocardial anti-apoptotic protein Bcl-2 to protect the mitochondrion, thus protecting cardiocytes and cardiac functions.
