Wnt/β-catenin signaling pathway is highly conserved in evolution,which involves in the regulation of a variety of biological processes such as embryonic growth,development,energy metabolism and stem cells maintenance.Aberrant activation of Wnt/β-catenin signaling pathway has a closely relationship with tumorigenesis.Investigating the role of Wnt/β-catenin signaling in glioma cell proliferation,invasion,apoptosis and tumor angiogenesis will provide novel therapeutic targets and intervening measures for glioma treatment.

The practices of military hospital medical equipment operation training were introduced, and the problems were pointed out in training content, organization and support. Some suggestions were put forward from the aspects of field medical equipment development, training plan, post-based training and etc so as to enhance the supportability of field medical equipment.

Many factors can result in X ray film overthick and overthin in medical X-ray radiation.In order to ensure the correctness of diagnosis and the focus can be presented at the proper time,it is very im- portant for the overthick and overthin film to be processed and corrected.It has been proved through the test that the satisfied result can be reached through the proper regulating measure such as making a copy of a film.

Objective To evaluate the effects of probucol combined with atorvastatin medication on blood levels of oxidized low-density lipoprotein (ox-LDL), lipoprotein-associated phospholipase A2 (Lp-PLA2), and the correlation of their changes in patients with acute coronary syndrome (ACS) undergoing percutaneous poronary intervention (PCI). Methods A total of 97 patients with ACS and undergoing PCI were randomly divided into two groups according to the date of admission:single medication group (n=42),the patients were taken atorvastatin 20 mg/d; and combined medication group (n=55),the patients were taken atorvastatin 20 mg/d with probucol 500 mg/d. The plasma levels of ox-LDL and Lp-PLA2 were measured in both groups before and 6-8 weeks after the medication. Then the results were compared and analyzed between two groups. Results (1) Before treatment there were no significant differences in levels of ox-LDL and Lp-PLA2 between two groups (P>0.05). After the treatment, the ox-LDL level was significantly decreased in combined medication group (P<0.01). After the treatment, the levels of Lp-PLA2 were significantly decreased than those before treatment in both groups (P<0.01). Compared with single medication group, levels of ox-LDL and Lp-PLA2 were significantly lower in combined medication group (P < 0.01). (2) After treatment, the absolute value of Lp-PLA2 decline (ΔLp-PLA2) was positively correlated with the absolute value of ox-LDL decline (Δox-LDL) in combined medication group (r=0.314, P=0.020). Conclusion Probucol combined with statin therapy can reduce ox-LDL and Lp-PLA2 levels, and with a positive correlation between them. Probucol can further decrease the level of Lp-PLA2 by inhibiting ox-LDL production, which may be one of the mechanisms of its anti-atherosclerosis.

Objective To analyze relationship between dual-source MDCT and pathology in renal cell carcinoma.Methods 129 patients with pathology were proved renal cell in our hospital from 2009 to 2012.According to the latest 2004 WHO pathological classification,CT features of renal carcinoma were compared with surgical and pathological results.Results The enhancement de-gree of lesions on contrast CT was correlated to the modal of renal malignant cells’ranking.There was no certain correlation be-tween integrity on the edge of the tumor in CT and pathological tumor capsular.The short-hair sign surrounding the margin of tumor strongly indicated renal capsule invasion (P <0.01).Agreement between CT-Robson staging and surgical-pathologic staging was good(Kappa=0.75).Conclusion The CT finding of renal cell carcinoma is correlated with tumor cell characteristic and inter-nal structure.Dual-source MDCT has important clinical value in the diagnosis of renal cell carcinoma.

OBJECTIVE To investigate the expression and significance of Fas, FasL and FADD in laryngeal carcinoma. METHODS Immunohistochemical method was used to examine the expression of Fas, FasL and FADD in laryngeal carcinoma specimen and adjacent normal tissues. RESULTS The positive rates of Fas and FADD in laryngeal carcinoma tissue were significantly lower than that in adjacent normal tissue, while FasL in laryngeal carcinoma tissue was higher than that in adjacent normal tissue(P

AIM: To study the synergistic protective effect of picrosideII and NGF for the oxidative stress on PC12 cells induced by hydrogen peroxide (H2O2). METHODS: The fluorescent probe 6-carboxy-2',7'-dichlorodihydrofluorescein (CDCFH) was used to assess the intracellular reactiveoxygen species (ROS) level, and MTT assay, morphological observation as well aslactate dehydrogenase (LDH) leakage were conducted to measure cellular injury. RESULTS: The H2O2-induced cytotoxicity was significantly attenuated in the presence of picroside II (25 μg/mL) and NGF (2 ng/mL). Cultures with this combined treatment possessed decreased level of ROS while increased cell survival, as compared to that of picroside II or NGF alone-treated cells. Accordingly, it was concluded that their synergistic protective activities against oxidative stress in vitro were demonstrated in various aspects including reversing morphological changes, enhancingthe ability of cell proliferation and ROS scavenging. CONCLUSION: Such action supports the therapeutic potential of picroside II and NGF in treating nervous disorders based on their synergistic effect.

Background:C-MET is expressed in a variety of tumor,and its expression may help to predict the prognosis of patients with gastric cancer. Aims:To explore the association of C-MET protein expression with survival in patients with stage Ⅲ gastric cancer. Methods:A total of 178 consecutive initially treated patients with stage Ⅲ gastric cancer from April 2010 to April 2014 at Beijing Pinggu Hospital were enrolled in this study. The expression of C-MET protein was determined by immunohistochemistry. Kaplan-Meier method was used to analyze the survival in patients with high C-MET protein expression and low C-MET protein expression,COX proportional hazards model was used to analyze the influence of various factors on prognosis. Results:C-MET protein was low expressed in 139 patients(78. 1%),and high expressed in 39 patients(21. 9%). Median survival(25. 1 months vs. 45. 0 months),1-year survival rate(69. 2% vs. 91. 4%),2-year survival rate(41. 0% vs. 84. 0%)were significantly decreased in high C-MET protein expression group than in low C-MET protein expression group(P all <0. 05). C-MET protein expression,N staging,and age were the influencing factor for prognosis of gastric cancer(P all <0. 05),however,gender and tumor differentiation were not related with prognosis(P>0. 05). Conclusions:C-MET protein expression rate is 21. 9% in patients with stageⅢgastric cancer,C-MET expression is significantly associated with survival;1-year survival rate is lower in patients with high C-MET protein expression.

OBJECTIVE To probe the pathogen′s distribution of ventilator-associated pneumonia(VAP),in order to offer the evidence of clinical therapy,prevent the onset of VAP and apply the antibiotics reasonably.METHODS We applied the methods of etiology,microscopic identification,bacteria culturing etc on 74 mechanical ventilation patients,and analyzed the etiology of early-onset and late-onset VAP in contrast.RESULTS Totally 121 pathogens were cultivated altogether in all 74 VAP patients.In the 36 pathogens which were cultivated from 29 early-onset VAP patients,there were 66.67% of simple culture(24 patients,24 strains) and 33.33% of co-culture(5 patients,12 strains),and in the 85 pathogens which were cultivated from 45 late-onset VAP patients there were 17.64% of simple culture(15 patients,15 strains) and 82.35% of co-culture(30 patients,70 strains).The proportion of co-culture in the late-onset VAP patients was prominantly higher than that in the early-onset ones(?2=27.821,P
